    [0001] The present invention relates to the displacement of belt conveyors of the type comprising a set of independent support stations, adapted to rest on the conveyor belt, a mobile conveyor installation comprising such a carriage, and associated moving method. sol and arranged successively along the length of the conveyor, and a conveyor belt carried by said support stations. Open-pit ore operations in which ore is collected over a large area require the implementation of means of transporting the ore to a point of storage or loading in vehicles.
    [0002] It is known to provide on the operating site an ore conveying facility. This commonly includes a first conveyor, called collector, disposed along an edge of the operating area. This first conveyor is fixed for the entire period of operation of the zone. A second conveyor is disposed transversely to the first conveyor. This second conveyor crosses completely through the exploited area. This conveyor is adapted to transfer the materials collected in the soil to the first conveyor, above which opens its release end. In order to allow exploitation of the entire area to be exploited, the second conveyor is movable, along the length of the first conveyor, to be in the current operating region. This second conveyor is generally displaced transversely to its conveying direction. It is known that the second conveyor comprises a succession of support stations distributed along the length of the conveyor belt of the conveyor. These support stations are independent and provide support for the conveyor belt.
    [0003] In order to allow the second conveyor to move a few meters transversely along its conveying direction, the support stations are most often connected to each other by an elongated link arranged along the length of the second conveyor. To ensure the displacement of each station successively along the length of the second conveyor, a machine requesting the link transversely to its direction of elongation is moved along the length of the second conveyor. This machine, consisting for example of a crawler construction machine, comprises a receiving member of the link rigidly connected to the machine. This organ encloses the link. It is moved along the length of the link by forcing the link to move gradually a few meters perpendicularly to the conveying direction of the second conveyor.
    [0004] A conveyor installation of this type is known for example from FR-A2 834 501. However, such conveyor systems are not entirely satisfactory. Indeed, with each movement of the machine, the second conveyor is moved transversely only a few meters, which requires having to circulate the machine many times from one end to the other of the second conveyor when the conveyor must be moved a significant distance. This results in the unavailability of the conveyor over a long period, which can have a negative effect on the production of the ore exploitation.
    [0005] An object of the invention is to facilitate the movement of the conveyor, and in particular to make it less time consuming and less tedious to move the conveyor over long distances. To this end, the subject of the invention is a carriage for transporting a belt conveyor of the aforementioned type, comprising a loading station for the support stations on the carriage, a station for unloading the support stations from the carriage, a guiding structure for guiding the support stations from the loading station to the unloading station, and means for moving the carriage in a direction of movement forming an angle with an axis connecting the loading and unloading stations.
    [0006] Such a carriage is particularly advantageous insofar as it does not merely solicit the stations transversely to the conveying direction by pulling on a link linked to said stations, as in the state of the art, but makes it possible to take advantage of charge the stations themselves and guide them to their destination. It is thus possible to move the stations, for each passage of the carriage along the conveyor, a distance greater than in the state of the art. According to particular embodiments of the invention, the carriage also has one or more of the following characteristics, taken alone or in any combination (s) technically possible (s): - the loading station comprises a rectilinear guide for guiding the support stations from an entrance of the loading station to the guide structure, said guide being adapted to be oriented substantially parallel to the direction of movement during the movement of the carriage in the direction of travel; the unloading station comprises a rectilinear guide for guiding the support stations from the guiding structure to an outlet of the unloading station, said guide being adapted to be oriented substantially parallel to the direction of displacement during the movement of the following trolley the direction of movement; the guide of the loading station and / or the guide of the unloading station comprises two guide rails spaced transversely from each other with respect to the guiding direction of the guide, said rails defining between them a window opening into a underside of the loading station, respectively the unloading station; - The guide structure comprises two guide rails spaced transversely from one another with respect to the guide direction of said structure, said rails defining between them a window opening into a lower face of the guide structure; the displacement means comprise a set of wheels together defining a contact surface of the carriage with the ground, each wheel being pivotally mounted on a chassis of the carriage so that its orientation relative to the chassis can be changed, the wheels being adapted to be oriented parallel to each other in the same direction, said direction constituting the direction of movement of the carriage; - A first pair of wheels is disposed at the interface between the loading station and the guide structure, and a second pair of wheels is disposed at the interface between the unloading station and the guide structure; - The wheels of each pair are mechanically linked to each other so as to be maintained substantially parallel to one another. The invention also relates to a mobile conveyor installation, comprising: a belt conveyor comprising a set of independent support stations, adapted to rest on the ground and arranged successively along the length of the conveyor, and a conveyor belt carried by said support stations, and a transport carriage as defined above, for transporting said belt conveyor. According to particular embodiments of the invention, the installation also has one or more of the following features, taken ( s) in isolation or in any technically possible combination (s): - the conveyor belt has a filiform flexible strand to which the support stations are connected; each support station comprises a frame defining a bearing surface of the station on the ground and, at a distance from said bearing surface, a member for cooperation with the carriage for loading the station onto the carriage and guiding from the station by the trolley; the cooperation member comprises at least two rods spaced apart from one another in a direction of elongation of the conveyor belt, each rod being oriented transversely to said elongation direction; the distance from each cooperation member to the bearing surface is less than the distance from the guiding structure to a contact surface of the trolley with the ground. The invention also relates to a method of moving a mobile conveyor installation as defined above, comprising the following steps: moving the carriage parallel to a direction of elongation of the conveyor belt, in a first direction, the loading station being offset transversely of a first side of the unloading station with respect to the direction of elongation of the conveyor belt, contacting a conveyor support station with an entrance of the loading station, loading of the support station on the carriage, the support station being guided from the entrance of the loading station to the guide structure, guiding the support station from the loading station to the unloading station by the structure for guiding and unloading the support station from the carriage, the support station being guided from the guide structure to an exit of the station unloading. According to a particular embodiment of the invention, the method also comprises the following steps: moving the loading station in a direction transverse to the direction of elongation of the conveyor belt, the unloading station remaining substantially stationary, up to the loading station is shifted transversely of a second side of the unloading station with respect to the direction of elongation of the conveyor belt, movement of the carriage parallel to the direction of elongation of the conveyor belt, in a second direction opposite the first direction, contacting a conveyor support station with the exit of the unloading station, - loading the support station onto the truck, the support station being guided from the exit of the unloading station to the to the guiding structure, - guiding the support station from the unloading station to the loading station by the guide structure, and - unloading the support station from the carriage, the support station being guided from the guide structure to the entrance of the loading station. Other characteristics and advantages of the invention will appear on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which: FIG. 1 is a partial view, of 2 is a partial view, from the side, of a belt conveyor belonging to the conveyor installation of FIG. 1; FIG. 3 is a view of a conveyor system according to the invention; Figure 4 is a rear perspective view of the support station of Figure 3, Figure 5 is a rear perspective view of a support station of the conveyor belt of Figure 2; is a perspective view, three-quarter rear, of a transport carriage belonging to the conveyor installation of Figure 1, - Figure 6 is an elevational view, from the side, of the carriage of Figure 5, and FIGS. 7 to 13 are diagrammatic views, from above, of the conveyor installation of Figure 1, during various stages of a method of moving the plant according to the invention. FIG. 1 shows a mobile conveyor installation 1. This installation comprises a belt conveyor 2 and a transport carriage 4 adapted to move the conveyor 2 transversely as it moves along the length of the conveyor 2.
    [0007] The conveyor 2 comprises a set of independent support stations 6 arranged successively one after the other, and a conveyor belt 8 supported by these stations 6. The strip 8 is shown in phantom in FIGS. 1 and 2 for more than clarity. The conveyor belt 8 is folded at its longitudinal ends (not shown) to form a loop. This loop is held at each end by return rollers (not shown) carried by end support stations (not shown) called foot and conveyor head. One of the return cylinders is rotated by a motor (not shown) for setting the band on itself. The band 8 defines, as illustrated in Figure 2, an upper strand 8A for the transport of products and a lower strand 8B allowing the return of the strip in the opposite direction to the conveying direction of the products. Each support station 6 has a length measured in the direction of circulation of the band between 1 m and 2 m. Depending on the length of the conveyor, the support stations 6 are distributed regularly and these are spaced apart, for example from 1 to 2 m. Referring to Figures 3 and 4, each support station 6 comprises a frame 12 adapted to rest on the ground, two cradles 14 for guiding the upper strand 8A of the strip and a cradle 16 for guiding the lower strand 8B of the strip. The frame 12 consists of a filiform frame. It comprises two support sections 22 on the ground. These two sections 22 together define a bearing surface of the station 6 on the ground. They are extended at their respective ends by legs 24 substantially vertical. The two legs 24 arranged on the same side of the strip 8 are connected to each other by a substantially horizontal longitudinal beam 26 supporting the upper guide cradles 14. These beams 26 each extend substantially parallel to the direction The support sections 22 of each support station 6 extend substantially parallel to each other. They are symmetrical to each other with respect to a median plane extending transversely to the direction of elongation of the strip 8. The support sections 22 and associated legs 24 delimit between them an angle slightly less than 900, this angle being for example equal to about 80 °. The angle formed between the legs 24 and the longitudinal beam 26 is slightly greater than 90 ° and is for example equal to 95 °. The legs 24 are generally converging towards each other each from their lower end connected to a bearing section 22 to their upper end connected to a beam 26. The upper cradles 14 for guiding the strip 8 are at number of two for each support station 6. They each extend transversely to the direction of circulation of the strip 8 and are arranged in the vicinity of the ends of the frame 12. Each guide cradle 14 rests only on the two longitudinal beams 26. It is immobilized with respect to these.
    [0008] More specifically, the upper guide cradles 14 each comprise a frame 30 consisting of a folded sheet extending transversely to the direction of elongation of the strip 8, a longitudinal beam 26 to the other. The frame 30 supports, on its upper surface, lugs 32 carrying three rotary rollers 34 arranged along the width of the frame 30. The rollers 34 define a hollow bearing surface for the band 8. The lower cradle 16 is made of a tubular support frame 40 carrying three rotary rollers 42 supported by tabs 44. The ends of the support frame 40 are connected to the legs 24, substantially in the middle part of these legs 24. As a variant, only certain support stations 6 comprise a guide cradle 16 of the lower strand 8B of the band 8. In particular, a support station 6 out of two is equipped with such a cradle 16. According to the invention, each support station 6 also comprises, at a distance of the support surface of the station 6 on the ground, a member 50 for cooperation with the carriage 4 for the loading of the station 6 on the carriage 4 and the guidance of the station 6 by the truck 4. This cooperating organ ration 50 comprises two rods 52 spaced from each other in the direction of elongation of the strip 8, each rod 52 being oriented transversely to said elongation direction. Said rods 52 are in particular interposed between the upper cradles 14. Each rod 52 is connected to the frame 12, in particular to the two longitudinal beams 26. Each rod 52 comprises a central section 54, extending from a longitudinal beam 26 to the longitudinal beam 26. another, and two end sections 56, each extending from a longitudinal beam 26 outwardly of the station 6. The central section 54 is bent, with a concavity oriented away from the bearing surface on the ground, so as not to hinder the passage of the upper strand 8A of the band 8 between the upper cradles 14.
    [0009] Each end section 56 is rectilinear and extends substantially parallel to the bearing surface of the station 6 on the ground. Returning to Figure 1, the conveyor 2 is also equipped with an elongate link 60 arranged in the direction of elongation of the conveyor belt 8. This elongated link 60 is connected to each support station 6. It is particularly attached in the middle of each rod 52 of the cooperation member 50 of each station 6.
    [0010] This slender link 60 consists of a filiform flexible strand formed for example of a wire rope or a chain. The expression "filiform flexible strand" designates any strand capable of being easily deformed and which has a low rigidity, so that it can be for example wound on itself.
    [0011] Preferably, this filiform flexible strand consists of a cable. This cable 60 is anchored at each of its ends so that they are immobilized relative to the ground. For this purpose, the ends of the cable are secured to dead bodies 10A, 10B (Figures 7 to 13) resting on the ground or piles driven into the ground.
    [0012] In addition, the cable 60 is held under tension by being retained at both ends. This voltage is such that the cable extends along a path having at each point a large radius of curvature and which is devoid of loosening zone of the cable. In particular, the cable is held generally tensioned between the successive support stations 6. To ensure its tension, the cable 60 is advantageously equipped with drawers. With reference to FIGS. 5 and 6, the carriage 4 comprises a rigid frame 61, a station 62 for loading the support stations 6 on the carriage 4, a station 64 for unloading the support stations 6 out of the carriage 4, a structure for guide 66 for guiding the support stations 6 sliding from the loading station 62 to the unloading station 64, and means 68 for moving the carriage 4 in a direction of movement DD 'forming an angle with an axis AA' connecting the loading stations 62 and unloading 64. The frame 61 is elongate in a longitudinal direction parallel to the axis A-A '. It comprises two end cross members 70 and, between said cross members 70, a frame 72. Each cross member 70 is formed by a tubular beam of rectangular section. Each cross member 70 is disposed at the interface between the guide structure 66 and one of the loading stations 62 and unloading 64. The armature 72 has a generally parallelepiped shape. It comprises four longitudinal members 74 defining four parallel longitudinal edges of the parallelepiped. It also includes uprights 76 connecting to each other the longitudinal members 74 aligned vertically with each other. It further comprises a plurality of intermeshed upper beams 78 connecting the upper members 74 to one another, and a plurality of interspersed lower beams 80 connecting the lower beams 74 to each other. The armature 72 finally comprises diagonals 82 extending from the intersection point of a post 76 with a spar 74 greater than the point of intersection of a post 76 adjacent the lower spar 74 vertically aligned with said upper spar. Each upright 76 extends downward beyond the lower spar 74. As a variant, only certain amounts 76 extend downward beyond the lower spar 74. The armature 72 is integral at its longitudinal ends with the crosspieces 70. Each cross-member 70 projects transversely on either side with respect to the armature 72. The displacement means 68 comprise a plurality of wheels 84, four in the example shown, arranged at the end angles of the frame 61. These wheels 84 together define a contact surface of the carriage 4 with the ground. The wheels 84 are adapted to be oriented parallel to each other in the same direction, said direction constituting the direction of displacement D-D '. Note that the orientation of each wheel 84 is defined as the direction of the intersection of the plane perpendicular to the axis of the wheel 84 with the contact surface of the carriage 4 with the ground. Each wheel 84 is orientable relative to the frame 61; in other words, each wheel 84 can be pivoted about an axis substantially perpendicular to the axis of the wheel 84 so as to change the orientation of said wheel 84. For this purpose, each wheel 84 is pivotally mounted on the chassis 61 by means of a yoke 86 flanking the axis (not shown) of articulation of the wheel 84, and said yoke 86 is pivotally mounted about a vertical axis, substantially perpendicular to the axis of articulation of the wheel 84, at a transverse end of one of the cross members 70. The wheels 84 comprise a first pair of wheels 84, positioned at the ends of the cross member 70 disposed at the interface of the guide structure 66 and the station 62, and a second pair of wheels 84, positioned at the ends of the crossbar 70 disposed at the interface of the guide structure 66 and the unloading station 64. The wheels 84 of each pair are mechanically linked to each other. the other so to be may parallel to each other. This mechanical connection is, in the example shown, constituted by an angle return chain 88, alternatively an angle return belt, connecting pulleys 89 each secured to a respective yoke 86 flanking the axis of the yoke. one of said wheels 84. The loading station 62 comprises a first end 90 forming an inlet, a second end 92, opposite the first end 90, forming a connecting end to the guide structure 66, and between said ends 90 , 92, a rectilinear guide 94 for guiding stations 6 sliding from the inlet 90 to the connecting end 92. The guide 94 is inclined upwards from the inlet 90 towards the connecting end 92. In particular the lower end 96 of the guide 94, at the inlet 90, is at a distance from the ground engaging surface less than the distance from the end sections 56 of the rods 52 of the cooperating member 50 of each support station 6 at the support surface of said station 6 on the ground, and the upper end 98 of the guide 94, at the connecting end 92, is at a distance from the ground contact surface substantially equal to the distance of the guide structure 66 to said contact surface. The guide 94 comprises two guide rails 100, 102 substantially parallel to each other and spaced transversely from one another relative to the guiding direction of the guide 94. The distance between these rails 100, 102 is greater than the distance separating the longitudinal beams 26 of each station 6 from each other, while being smaller than the distance between the transverse ends of the cooperation member 50. Each rail 100, 102 thus defines, for each support station 6 received in the guide 94, a support surface of one of the end sections 56 of each rod 52 of the cooperation member 50 of said station 6. The rails 100, 102 delimit between them a window 104 opening into a lower face of the loading station 62; in other words, no element of the loading station 62 extends between the rails 100, 102, and the space between the window 104 and the contact surface of the carriage 4 on the ground is left free. The window 104 also opens into the first and second ends 90, 92 of the loading station 62. Thus, the window 104 forms a passage for the support stations 6 between the inlet 90 and the connecting end 92 of the loading station. 62. The guide 94 is adapted to be oriented substantially parallel to the direction of movement DD 'during the displacement of the carriage 4 in said direction D-D'. For this purpose, the guide 94 is pivotally mounted on the frame 61 so as to be selectively oriented parallel to the axis A-A 'or in a direction forming an angle with said axis A-A'. In particular, hinges 106 are mounted transversely on either side of the connecting end 92, so as to allow the pivoting of each rail 100, 102 relative to the frame 61 about a vertical axis, and a rod 108, oriented substantially parallel to a connecting direction of the hinges 106, is articulated to the rails 100, 102 away from the hinges 106, so as to maintain the rails 100, 102 substantially parallel to each other.
    [0013] The unloading station 64 comprises a first end 110 forming an outlet, a second end 112, opposite the first end 110, forming a connecting end to the guide structure 66, and, between said ends 110, 112, a rectilinear guide 114 to guide the stations 6 sliding from the connecting end 112 to the outlet 110. The axis AA 'connecting the loading stations 62 and unloading 64 to each other is defined as being the axis connecting the middle of the connecting end 92 in the middle of the connecting end 112. The guide 114 is inclined downwards from the connecting end 112 to the outlet 110. In particular, the lower end 116 of the guide 114 at the outlet 110 is at a distance from the ground engaging surface less than the distance from the end sections 56 of the rods 52 of each support station 6 to the support surface of said station 6 on the floor, and the upper end 118 of the guide 114, at the connecting end 112, is at a distance from the ground engaging surface substantially equal to the distance from the guide structure 66 to said contact surface. The guide 114 comprises two guide rails 120, 122 substantially parallel to each other and spaced transversely from one another relative to the guide direction of the guide 114. The distance between these rails 120, 122 is greater than the distance separating the longitudinal beams 26 of each station 6 from each other, while being smaller than the distance between the transverse ends of the cooperation member 50. Each rail 120, 122 thus defines, for each support station 6 received in the guide 114, a support surface of one of the end sections 56 of each rod 52 of the cooperation member 50 of said station 6.
    [0014] The rails 120, 122 delimit between them a window 124 opening into a lower face of the unloading station 64; in other words, no element of the unloading station 64 extends between the rails 120, 122, and the space between the window 124 and the contact surface of the carriage 4 on the floor is left free. The window 124 also opens into the first and second ends 110, 112 of the unloading station 64. Thus, the window 124 forms a passage for the support stations 6 between the connecting end 112 and the outlet 110 of the unloading station 64 The guide 114 is adapted to be oriented substantially parallel to the direction of displacement DD 'during the displacement of the carriage 4 in said direction D-D'. For this purpose, the guide 114 is pivotally mounted on the frame 61 so as to be selectively oriented parallel to the axis A-A 'or in a direction forming an angle with said axis A-A'. In particular, hinges 126 are mounted transversely on either side of the connecting end 112, so as to allow the pivoting of each rail 120, 122 relative to the frame 61 about a vertical axis, and a rod 128, oriented substantially parallel to a connecting direction of the hinges 126, is articulated to the rails 120, 122 away from the hinges 126, so as to maintain the rails 120, 122 substantially parallel to each other. The guide structure 66 is positioned below the frame 61. It is integral with the frame 61 and is fixed relative thereto. The guide structure 66 is at a distance from the ground contact surface greater than the distance of the cooperation member 50 from each support station 6 to the support surface of said station 6 on the ground, in particular greater than the distance of the end sections 56 of the rods 52 of the cooperation member 50 to the bearing surface of said station 6 on the ground. The guiding structure 66 is rectilinear and is oriented substantially parallel to the axis A-A '. It extends from the loading station 62 to the unloading station 64. The guide structure 66 comprises two guide rails 130, 132 substantially parallel to one another and spaced transversely from one another relative to the guide direction of the guide structure 66. The distance between these rails 130, 132 is greater than the distance separating the longitudinal beams 26 of each station 6 from each other, while being less than distance between the transverse ends of the cooperation member 50. Each rail 130, 132 thus defines, for each support station 6 received in the guide structure 66, a support surface of one of the end sections 56 of each rod 52 of the cooperation member 50 of said station 6.
    [0015] Each rail 130, 132 is in particular vertically aligned with two longitudinal members 74 of the frame 61, and is fixed to the lower end of the uprights 76 connecting said two longitudinal members 74 to one another. The rails 130, 132 delimit between them a window 134 opening into a lower face of the guide structure 66; in other words, no element of the guide structure 66 extends between the rails 130, 132, and the space between the window 134 and the contact surface of the carriage 4 on the ground is left free. The window 134 also opens at the longitudinal ends of the guide structure. Thus, the window 134 forms a passage for the support stations 6 between the connecting end 92 of the loading station 62 and the connecting end 112 of the unloading station 64.
    [0016] A method of moving the mobile installation 1 will now be described, with reference to Figures 7 to 13. In a first step, shown in Figure 7, the carriage 4 is positioned on the conveyor 2. For this purpose , the carriage 4 is placed next to the foot of the conveyor 2, aligned with the direction of elongation of the band 8, the guides 94, 114 of the loading and unloading stations 62 being oriented substantially parallel to the axis AA ' and the wheels 84 being oriented so that the direction of displacement DD 'is substantially coincident with the axis A-A'. Then the carriage 4 is moved towards the head of the conveyor 2, parallel to the direction of elongation of the strip 8. In doing so, the support stations 6, starting with the head of the conveyor 2, successively come into contact with the 90 of the loading station 62. More specifically, it is the end sections 56 of the rods 52 of the cooperation member 50 of each station 6 which come into contact with the lower end 96 of the guide 94.
    [0017] The displacement of the stations 6 in the direction of elongation of the band 8 being prevented by the slender link 60, and the carriage 4 moving in said direction, each station 6 is thus found to slide along the guide 94 of the loading station 62, to the connecting end 92. The upper end 98 of the guide 94 being at a distance from the ground engaging surface greater than the distance from the end sections 56 of the rods 52 of the cooperation 50 of each support station 6 to the support surface of said station 6 on the ground, the support surface of the station 6 is carried away from the ground during the sliding station 6 along the guide 94 Once at the connecting end 92, the support station 6 continues to slide along the guide structure 66 to the unloading station 64. The guide structure 66 is at a distance from the contact surface with the ground sup greater than the distance from the end sections 56 of the rods 52 of each support station 6 to the support surface of said station 6 on the ground, the support station 6 does not touch the ground when it is sliding along the guide structure 66, so that this sliding takes place with a minimum of friction.
    [0018] Arriving at the connecting end 112, the support station 6 begins to slide along the guide 114 of the unloading station 64, from the connecting end 112 to the outlet 110. The lower end 116 of the guide 114 being at a distance from the ground engaging surface less than the distance from the end sections 56 of the rods 52 of the cooperating member 50 of each support station 6 to the bearing surface of said station 6 on the In the ground, the support station 6 returns to contact with the ground during its sliding along the guide 114.
    [0019] The carriage 4 is thus moved until it has passed the dead body 10B disposed as close as possible to the foot of the conveyor 2, as represented in FIG. 8. As soon as the carriage 4 arrives in this position, its displacement in the direction of elongation of the band 8 is stopped. The wheels 84 disposed at the interface between the guide structure 66 and the unloading station 64 are then pivoted so as to be oriented substantially perpendicular to the direction of elongation of the strip 8, then the unloading station 64 is moved transversely at the direction of elongation of the band 8, the loading station 62 remaining substantially stationary. The dead body 10B is simultaneously moved to the unloading station 64. At the same time, the guides 94 and 114 are each pivoted so as to remain parallel to the direction of elongation of the strip 8. Once the unloading station 64 is shifted transversely to the direction of elongation of the strip 8 by a predetermined offset, as shown in FIG. 9, the displacement of the unloading station 64 is stopped. The loading station 62 is then shifted transversely of a first side of the unloading station 64 relative to the direction of elongation of the conveyor belt 8. The wheels 84 are then all pivoted so as to be reoriented substantially parallel to the direction 8. Then the displacement of the carriage 4 parallel to the direction of elongation of the band 8 resumes, still towards the head of the conveyor 2. In doing so, the support stations 6 which retouch the ground after slid along the carriage 4 are shifted transversely, relative to their original position, by an offset equal to the predetermined offset applied to the unloading station 64. The carriage 4 is thus moved until the conveyor head 2 is engaged in the loading station 62, as shown in Figure 10. As soon as the carriage 4 arrives in this position, its displacement parallel to the said Elongation of band 8 is stopped. The wheels 84 disposed at the interface between the guide structure 66 and the loading station 62 are then pivoted so as to be oriented substantially perpendicular to the elongation direction of the strip 8. Then, while the unloading station 64 remains substantially stationary, the loading station 62 is moved transversely to the direction of elongation of the strip 8, in the same direction as the previous direction of movement of the unloading station 64. The dead body 10A located closer to the head of the conveyor 2 is simultaneously moved to the loading station 62. At the same time, the guides 94 and 114 are each pivoted so as to remain parallel to the direction of elongation of the band 8.
    [0020] Once the loading station 62 has shifted transversely from twice the predetermined offset previously applied to the unloading station, as shown in FIG. 11, the movement of the loading station 62 is stopped. The loading station 62 is then shifted transversely from a second side of the unloading station 64 relative to the direction of elongation of the conveyor belt 8. The wheels 84 are then all pivoted so as to be reoriented substantially parallel to the direction 8. Then the carriage 4 is moved parallel to the elongation direction of the band 8, but this time towards the foot of the conveyor 2, that is to say in the direction opposite to the direction of movement previously applied. In doing so, the support stations 6 are found to slide on the carriage 4 either from the entrance 90 of the loading station 62 to the exit 110 of the unloading station 64, but from the exit 110 to the In particular, the support stations 6 are loaded onto the carriage 4 at the unloading station 64, before being guided by the guiding structure 66 to the loading station 62, and then unloaded at 62. The support stations 6 which then retouch the ground after sliding along the carriage 4 are offset transversely, with respect to their original position, by an offset equal to twice the predetermined offset applied to the position of the loading station 62. unloading station 64.
    [0021] The carriage 4 is thus displaced until the foot of the conveyor 2 is engaged in the unloading station 64, as shown in FIG. 12. As soon as the carriage 4 arrives in this position, its displacement parallel to the direction of elongation of the band 8 is stopped. The wheels 84 disposed at the interface between the guide structure 66 and the unloading station 64 are then pivoted so as to be oriented substantially perpendicular to the direction of elongation of the strip 8. Then, while the loading station 62 remains substantially stationary, the unloading station 64 is moved transversely to the direction of elongation of the strip 8, in the same direction as the previous direction of movement. The dead body 10B is simultaneously moved to the unloading station 64. At the same time, the guides 94 and 114 are each pivoted so as to remain parallel to the direction of elongation of the strip 8. Once the unloading station 64 is shifted transversely of the same predetermined offset as before, as shown in Figure 13, the displacement of the unloading station 64 is stopped. The support stations 6 are then all aligned with each other.
    [0022] The wheels 84 are then all pivoted so as to be reoriented substantially parallel to the direction of elongation of the band 8, then the carriage 4 is moved in the direction of elongation of the band 8, so as to be clear of the conveyor 2 For this purpose, the carriage 2 is moved away from the head of the conveyor 2, until all the support stations 6 are unloaded from the carriage 4 and rest on the ground. The displacement of the installation 1 is then completed. Thanks to the invention described above, the movement of the mobile installation 1 operates very easily. It is possible to offset the support stations 6 by a large transverse shift with each movement of the carriage 4 parallel to the direction of elongation of the band 8, which allows the conveyor 2 to be shifted by the desired distance with a minimum number The mobile installation 1 can thus be moved faster than the existing mobile installations. In addition, the moving of the mobile installation 1 is carried out with a minimum of friction, since the stations 6 do not touch the ground during their movement, and they are in contact with the carriage 4 that along the road. a reduced surface, in this case the end sections 56 of the rods 52. The traction of the carriage 4 can therefore be performed with a machine of reduced power.
