    The invention relates to devices for the development of steeply dipping deposits, in particular coal seams, and can be used in the extraction of minerals by the underground method using mechanized: complexes.
    A device that develops coal-bearing coal seams is known, which consists of a lava extending along the entire length and containing, a link of a ladder-like supporting and guiding frame, the longitudinal beam of which, from the clearing side, forms a guide for the coal plow, and the longitudinal beam from the laying side carries back-up wall. Both longitudinal beams are connected by cross-beams, which are formed by BaHbJ retaining frames, having racks 1 unstressed between the roof and the soil.
    However, this device is heavy and cumbersome, during development, the individual support frames at the foot of the drift are removed, and at the head drift they must be mounted again.
    The closest to the proposed one is a mechanized complex for steep seams containing a ladder-shaped frame of longitudinal and transverse beams, between which are placed hydraulic support sections, having a base, floor and hydraulic racks associated with, transverse beams, a guide for excavation machine mounted on the downhole side of the longitudinal beam, with PG single beams made of links and interconnected pivotally in the plane of the reservoir, while the support section is pivotally connected displacement cylinders mounted in transverse beams, the rods of which are pivotally connected to transverse beams 2.
    However, this device is also cumbersome, installing it into steeply falling lava requires considerable time and labor.
    The aim of the invention is to simplify the design, while increasing efficiency and facilitating assembly and disassembly.
    The goal is achieved by the fact that in a mechanized complex for steep seams containing a ladder-shaped frame of longitudinal
    transverse beams, between which hydraulic support sections are located, which have a base, an overlap, and hydraulic legs associated with
    transverse beams, a guide for the excavation machine, mounted on the longitudinal beam located on the downhole side, the longitudinal beams are made of links and are interconnected pivotally in the plane of the formation, and the support sections are hinged. associated with cylinders of displacement hydraulic jacks installed in transverse beams, the rods of which are connected with transverse beams, the frame is made of separate U-shaped frames. each of which contains a transverse and two links of the longitudinal beams, while the transverse beams are connected to the longitudinal by means of vertical hinges.
    The link of the longitudinal beams can be made telescopic.
    Sections can be provided with connected traction plate springs, by means of which the legs are joined at the base and overlapped.
    In addition, the transverse beams can be provided with pivotal pivots mounted on them in the base plane, by means of which the transverse beams are connected to displacement hydraulic jacks.

    Between the drifts 1 there is a concurrent steeply dipping clearing lava 2, limited by coal face, 3 and a laying space 4. In a steeply dipping lava 2, a mechanized complex 5 is installed, containing a hinge supporting and guiding frame 6, which runs along the entire length of the lava, K it is attached and guided by separate sections 7 of the hydraulic support. The supporting and guiding frame 6 consists of two parallel longitudinal beams 8 and 9 connected to each other by means of transverse beams 10 into a ladder-shaped frame. Sections 7 are located between two adjacent transverse beams Yu. A longitudinal guide 11 is installed on the longitudinal beam 9 on the side of the mining machine, for example, coal plow 12. Instead of coal plow 12, other cutting machines, machines and other mining equipment can also be used. Both longitudinal beams 8 and 9 consist of links, which at the ends through the typhus hinges 13- with the hinge axes extending in the direction of development, are connected to each other movably in the reservoir surface. Each longitudinal beam 8 and 9 thus consists of flexible beams which can be adjusted to the course and unevenness of the soil 14 of the formation. The lengths of the longitudinal beams B and 9 may have protrusions in the form of sliding skis 15 on the underside, with the help of which a length of the beam near it rests on the soil of the formation. The link of the longitudinal beams 8 and 9 is connected by means of cross-shaped cross beams 10, which, in turn , are hinged to the longitudinal beams (Fig. 5) by means of connecting hinges 16, which consist of pin joints with perpendicular bases of the hinges. Due to such articulations, installation movements of the ladder-like carrier and guide frame 6 are possible, when adapted to the respective operating conditions, while the ladder-like carrier and guide frame 6 allows installation on a slightly overturned clearing face 3. In this case, the floor between the cross-sectional transverse beams 10 of the ladder-shaped supporting and guiding frame 6 are not rectangular, but rhomb-shaped. Taking into account the mentioned installation movements, the links of the longitudinal beams can be made telescopic with the possibility of changing their length. A hydraulic cylinder 17 pivotally attached can be installed between the parts of the beam. The entire ladder-shaped supporting and guiding frame 6 is made in the form of a double lamellar chain, the lamellar chains of which, formed by longitudinal beams 8 and 9, are interconnected by means of pivotally attached cross-sections of cross-shaped transverse beams 10. Lining between transverse heads 10 of the lining section 7 are attached only (to the upper sloping transverse beams. The sections 7 of the support comprise four hydraulic posts 18 arranged along a rectangle, connected in pairs by tops 19. The legs 18 are interconnected through a square astine springs 20, which also bind their supports 21, with both joints from the leaf springs 20 of both pairs of struts, in turn, in the middle zone are connected via a plate-spring connection 22. Thus, an H-shaped plate-spring system is created, which makes it possible to independently set up the height of the uprights 18 to fit the unevenness of the recumbent side of the field. At some distance from this plate-spring system, the upper ends of the cylinders of the uprights 18 are connected through a corresponding H-shaped plate dinner | hydrochloric system which is formed plas .tinchatymi springs 23 and 24 (fig.Z, | 5 and 7J. The suspension of sections 7 is supported on the corresponding upper transverse bags 10 through feed devices having a hydraulic cylinder 25 POD2.CHU double action with a piston rod 26 (Fig. 3, 4 and b). Section 7 is connected to cylinder 25 via a traction element consisting of a lower pair of earrings 27 and a separate upper earring 28. Earrings 27 and 28 at one end through hinges 29 and 30, the axes of which are located in the direction of development, are attached to the connecting node 31 fixed on the corresponding cylinder 25. Both parallel earrings 27 are at other ends through hinges 32 with axes located in the direction of development, connected to the connecting elements 33, which are attached in the middle of the spring connection 22. The upper link through the ball 34 is connected to the connecting element 35, which is placed in the middle of the upper spring connection on the lower side. Godard communication section 7 to the stepping cylinder 25 can be installed in a large dia pazone adjustment fastener for adaptation to irregularities in the footwall deposit, while rack sections 18 7 simultaneously retained by the oblique installation and tipping of drop formation. Since the cylinder 25 can rotate around the piston, at the same time it is possible to rotate section 7 relative to the transverse beam 10. Sections 7 are connected in the feed direction with varying angle with transverse beams 10. For this, U-shaped turn bars are placed on the cross beams 10 36, which are connected to transverse beams through the hinge 37 by the front ends. The hinge 37 also includes the ends of the piston rod 26 of the corresponding stepper cylinder 25 on the turn bar. The hinge connection 37 is made in such a way that the turn plate 36, together with the stepper cylinder 25, rotates in a parallel plane lying on the side of the field relative to the transverse beam 10, while the corresponding turning position can be fixed. The crossbeam 10 at the end of the tab has a plate 38 which is blocked by a counterplate 39 fixed at the opposite end of the turn bar 36 (FIGS. 3 and 6). Both plates 38 and 39 are moved relative to each other through the arcuate slot 40 and fixed through the pin connection 41 in the corresponding rotational position. Thus, the swivel bar 36 with the stepper cylinder 25 can be rotated by an angle: Sotno the transverse beam 10 from the middle position to both sides by a certain amount, for example 3, and can be fixed in the corresponding rotation position with the help of the insertion pin. As a result, the lining sections 7 can be guided in such a way that at each step in the direction of development they are slightly shifted up the slope of the formation, due to which offset by the dip of the formation is compensated or it is possible to install the entire ladder-shaped bearing and guiding frame 6 on the clearing face, set at an angle to the dip. The guide 11 for the mining machine also consists of separate guide links. Dp of installation of the plow 12 or another mining machine, the guide 11 together with the links of the longitudinal beam 9 rotates slightly around the longitudinally clearing shaft of the axis up and down. For this purpose, the hinges 16 are made with the possibility of rotation around the hinge axis that passes along the clearing eye (Fig. 5). Between the beams 10 and the longitudinal beams 9 at a certain distance from each other, the hinge bar (installed hydraulic mounting cylinders 42, with which the angular installation of the guide 1I for the mining machine can be made along the arrow P in Fig. 5. On the longitudinal beam 8, facing the tab, is installed, along the height by means of a hydraulic cylinder 43, a tab guard 44, which separates the lava space along the entire height from the tab space 4. On the longitudinal beam 9 facing the lava there is a mouth The hydraulic barrier 45, which is height-adjustable using the hydraulic cylinder 45, separates the development space from the lava space at full height. The hinges 13, which connect the links of the beams to each other, are designed as quick-release pin joints. The ladder-shaped supporting and guiding frame 6 therefore consists of a plurality of segments arranged in a row one after another, each of which includes a cladding-shaped transverse beam 10 and the links of the longitudinal beams 8 and 9 connected to it by the hinges 16 in a U-shaped frame. The areas formed by the U-shaped frames create together with the sections 7 of the lining, joined by the transverse beams 10 through (Feed mechanism, the transport unit, which from the drift I can be inserted into 2, after which the transport unit by means of the pin joint 13 is driven by a lengthwise longitudinal section of the supporting and guiding frame in the lava 6. Figs. 8 and 9 show a device for inserting the transport unit, In the main drift 1, the rails 48 are directed along the rails 47 in the direction of development, connection data through a single double acting stepper cylinder 49 with the second sled 50, which can have a drive 51 for the mining machine and also rest on rails 47. It is advisable to fix the rails 47 by means of anchors in the drift G. On the bands 48 in the hinges 52, a tilting table 53 is installed, which protrudes from the head drift 1 into steeply dipping lava 2 and here rests on a flat notch 54 of the recumbent side of the field. On the table is mounted a feed slider 55, which by means of a hydraulic feed cylinder 56 from the raised position (Fig. 8 may be lowered down to the entrance to the lava. The feed cylinder 56 is located in the table and is connected by a piston rod 57 in the hinges 58 to the feed slide 55. The assembly is carried out as follows. Three sections of complex 5 with sections of 7 supports (Fig. 8) are placed in the lava. Sections of complex 5 are interconnected through pin-joint articulated joints 13 to form longitudinal beams 8 and 9. Each section of the mechanized comlex 5 has a U-shaped frame formed by a cross-section-like transverse beam 10 and two links of beams 8 and 9, supported by section 7 of the Scotror section 7 connected to the transport unit. The sections of mechanized m; mounted in lava; Omshlex 5 are prevented from creeping over the dip of the formation by the fact that the upper section itself is fixed on the plate 53, for example. by means of pins 59, which are fixed on the table 53 and enter into the pin holes of the links baloz 11 8 8 and 9 of the corresponding section of complex 5. The pins 59 can be moved using a special starting device, such as a hydraulic starting cylinder. The next section of the mechanized complex 5, which also includes the cross beam 10 formed by the cross beam 10 and the links of the beams 8 and the 9П-shaped frame with the cross section 7, is placed on the uplifted feed slider 55. Installing it on the feed slider 55 may occur, for example, by means of a waist 60, which is attached to the fastener 61 drift. Section The complex 5 is attached to the feed slider 55 by means of pins 62, which can also be moved by means of a hydraulic cylinder or other device. After that, the feed slider 55 is lowered by moving the feed cylinder 56 until the ends of the links of the beams 8 and 9 are motirated and j) aHee of the installed section of the mechanized complex 5, forming a swivel 13. Next, the pins 59 are clamped and assembled the area is lowered into the lava by further lowering the feed slide 55, while the mounted section of the complex 5 is positioned before the previously installed section of the complex 5. Thereafter, the pins 59 and the feed slide 55 are set again after o freeing the pins 62, the R upper position rises (Fig. 8). The following sections are mounted in the same way. As soon as the entire mechanized complex 5 is introduced into lava 2 from bare drift 1, the hydraulic pillars of 18 sections 7 of the support and fur of the fixed PXejji complex in inclined lava are moved apart. At the same time, in the complex, the weft is installed, the link of the guide 11 for the mining machine, and the cut-off fence 44 of the bookmark and the fence 46. After mounting the entire mechanized complex 5, the tilting table 53 with the feed slider 55 is released} 1 hinge connection D1: 1 Note 52 is removed from the slide 48. The slide 48 (FIG. 10) is connected to the last section of complex 5, for example, via a barbell or chain drive 63, so that the entire mechanized complex is additionally kept from slipping. In some cases, you can refuse extra mount. During mining, the support section 7 is fed in the direction of development of a relatively ladder-shaped bearing and direction of the ice carcass 6, after which, by the opposite load of the stepping cylinders 25, the bearing and guide frame 6 is shifted in one step or gradually. The slides 48 and 50 using the stepper cylinder 49 are likewise supplied in the direction of development along the rails 47. Figures 4 and 11 show an embodiment of a device for inserting and lowering the development device. Such a device in the region of the upper end of lava 2 has on both sides of a mechanized complex one hydraulic cylinder 64 each, supported via anchor 65 by anchor 66, which is clamped between the soil and the roof by means of a hydraulic anchor rod 67. Both anchors 66 carry skis 68 on which longitudinal beams 8 and 9 are supported. On skis 68, latch bolts 70 inserted by means of a hydraulic cylinder 69 are placed, by means of which a piece of a development device inserted into the lava can be secured against sliding down the seam Both anchors 66 through intermediate beams 71 are connected to anchors 72, each of which is also attached to the lava by means of a hydraulic anchor rack 73. The stem of the hydraulic cylinder 64 is connected through the hinge 74 to the ski 75. which supports and guides the corresponding longitudinal beam 8 (9}. The following crossbar pin 76 is inserted on the ski bearing parts, which is activated by means of a hydraulic connecting cylinder 77 and by means of which The section of the mechanized complex 5 introduced into the lava can be locked by the piston rod of the hydraulic cylinder 64. The lowering device works as follows: Four sections of complex 5 are inserted into the lava 2, which are connected to each other through pin pivots s 13 (Fig. 1 l |. To enter the next section of complex 5, its head O1 track 1 is connected to the last of the installed sections of complex 5 through the hinge joints 13. The extended hydraulic cylinders 64 engage with beater pins 76 with links of beams 8 and 9 the last mounted section of complex 5. After releasing the pins 70 by moving the hydraulic cylinder 64, the entire chain of sections of complex 5 is lowered into lava 2, while the last section of complex 5 is pulled out of head drift 1 into lava 2. After that, pins 70 again are set, and sti you 76 are released to push the cylinder 64 and the lower section of the following in the lava. As soon as the entire mechanized complex is introduced into lava 2, the described lowering device can be removed from the lava. In order for sections 7 of the supports to move with a sufficiently large pitch, it is recommended to establish the distance between the longitudinal beams 8 and 9 so that it approximately corresponds to the double step of movement of sections of the support 7. During the delivery of the section 7, the supports are guided by cross-section transverse beams in a suspended state, with the possibility of height adjustment. Due to the swivel of the transverse beams with the longitudinal beams, it is possible to displace the longitudinal beams in the form of a parallelogram so that you can work with the overturned clearing face or set the tilting angle of the clearing face. In described. In one embodiment, the ladder-shaped supporting and guiding frame 6 is formed from separate U-shaped frames, which are articulated through hinges. Instead, you can separate the links of the carrier | and guide frame 6 to form from 1-shaped frames, in addition, cross-section-like transverse beams are located in the middle zone between the two links of beams 8 and 9. The dismounting of the development device from the lava is carried out in the reverse order using the described lowering device. The proposed mechanized complex has a fairly simple design, the mobility of its individual units provides adaptability to the corresponding conditions of operation, movement direction during installation and deposit.
