    DESCRIPTION
    Object of the invention
    The present invention, as expressed in the statement of this specification, refers to a mobile platform for work between two parallel supports; where the mobile platform has four vertical wheels that rest on upper surfaces of the two parallel supports, so that the mobile platform travels in a controlled manner along said parallel supports. For this, at least one operator is located on a support floor of the mobile platform to be able to control at all times the mobility and blockage of the advance of the mobile platform when necessary. Thus, with the mobile platform of the invention, all the risks that are not controlled by the placement and manipulation of the safety nets and other elements associated with said nets that are currently being used as security means are eliminated.
    Technical problem to solve and background of the invention
    At present, the technological evolution of construction systems has experienced a great boom in recent years. The regulations on collective protections are limited against the current needs of the work, particularly the Safety Networks norm, since numerous systems not currently contemplated in the mentioned norm are currently being used.
    These systems with safety nets have been designed thanks to the advantage of this textile element due to its adaptability and versatile character, which facilitates the use especially in works of difficult execution, such as bridges, industrial buildings or, buildings with numerous setbacks, outgoing, etc. However, the guarantee of these systems depends on the complete set (network, supports, accessories), their correct assembly and their use.
    In Spain, the Occupational Risk Prevention Law (LPRL) establishes in its chapter III the rights and obligations derived from the basic right of workers to their protection. It also establishes (art.15) a series of general principles to follow, such as the adoption of measures that put collective protection before the individual, taking into account

    the evolution of technology counts, etc.
    The RD 1627/1997 of construction works establishes in its annex IV, part C, point 3, regarding the minimum health and safety provisions to be applied to the works, the use of safety nets as a collective protection device.
    However, there is concern about the evident deficiencies in preventive matters that involve the placement of networks in the construction of bridges including, as it could not be otherwise, the placement and maintenance of the networks under the strictest control according to current regulations . Even so, the assembly of these networks and their auxiliary means in structures for the execution of bridges entails risks for the health of the workers and for the physical integrity of these, which cannot be minimized, even more so there are residual risks of difficult control.
    These risks are those derived from the placement of the system components, where workers have to make use of individual protections with the risks that this entails, for the placement of supports, articulated arms, vertical and horizontal positioning of the assembly, networks and others. Useful that make up the system.

    Description of an example of realization of the invention
    Considering the numbering adopted in the figures, the mobile platform 1 for the placement of pieces between two parallel supports 2 comprises an extensible structure formed by a base 3 that is constituted by two complementary parts: one anterior 3a and another posterior 3b; linked by a telescopic coupling that includes two parallel male elements 4 fixed to one of the two parts of the base 3, while the other even part of the base 3 has female elements 5, in whose interior space the two elements are telescopically male 4. In one embodiment the parallel supports 2 are two beams.
    The male elements 4 and the female elements 5 are arranged in transverse directions that are perpendicular to longitudinal directions where the two parallel supports 2 meet.
    The base 3 of the mobile platform 1 has four vertical wheels: two tractors 6, and another two 6 ’that have a crazy turn. The four vertical wheels 6, 6 ’are arranged in corner areas of said base 3; where mobile platform 1 supports through its

    30
    35
    four vertical wheels 6, 6 ’on upper surfaces 2a of the parallel supports 2.
    The two parts of the base 3 of the mobile platform 1 comprise frame-shaped structures that include longitudinal sections 7 and transverse sections in accordance with the male elements 4 and female elements 5 which are continuation of the transverse sections of one of the parts of the base 3. On the longitudinal sections 7 of the base 3, opposing grid plates 8 are fixed which constitute a support floor where the operators step on.
    Said opposing plates 8 have opposite end sections that are linked to each other by means of a telescopic coupling that allows varying the width of the mobile platform 1 according to the distance between the pairs of parallel supports 2 ensuring the maintenance of the ground without generating gaps between the opposing plates 8 when the width of the mobile platform 1 is varied, thus avoiding accidents.
    For this, the telescopic coupling of the opposite end sections of the two opposing plates 8 is a tongue and groove coupling consisting of groups of fins 8a and groups of recesses 8b into which the fins 8a are fitted; where the fins 8a and the recesses 8b are located in directions parallel to the relative displacement between the two opposing plates 8. It is a tongue and groove coupling like two combs where some spikes (fins 8a) of one of the combs are located in recesses 8b of the other even comb and vice versa.
    The mobile platform 1 includes a regulation device 43 to adapt its width to the distance between the parallel supports 2. Said regulation device 43 comprises two lateral spindles 9 that associate the two parts 3a, 3b of the base 3, where said lateral spindles 9 rotate by means of the transmission of a central axis 10 coupled to the front part 3a of the base 3. On one end portion of the central axis 10 a double pin 11 is embedded while on the other extreme portion of the central axis 10 a first conical pin 12 that meshes with a second conical pin 13 connected to a lower crank 14 so that the width of the mobile platform 1 can vary with its rotation according to the distance between the two parallel supports 2 on which the mobile platform 1 rests.

    The two axially immobilized lateral spindles 9 are coupled in through holes of two longitudinal sections 7 of the front part 3a of the base 3 and are also coupled to nuts 15 fixed to one of the longitudinal sections 7 of the rear part 3b of the base 3, at the same time that in said lateral spindles 9 end pins 16 linked to the double pin 11 are fixed by two opposing chains 17.
    When the regulation device 43 is actuated by manually turning the lower crank 14, its movement is transmitted to the two lateral spindles 9 arranged in parallel, where their turns cause a relative displacement in opposition to the two parts 3a, 3b of the base 3 of the mobile platform 1 to adapt its width to the distance between the two parallel supports 2. The tension of the two chains 17 is maintained by means of crazy pinions coupled in integral axes to the front part 3a of the base 3.
    The mobile platform 1 includes a transmission device 44 that transmits mobility to the two vertical drive wheels 6 to be able to move said mobile platform 1 along the two parallel supports 2, where said transmission device comprises two telescopic axes 18 in opposition which converge at some ends in a gearbox 19 from which an upper crank 20 starts, whose rotation transmits the rotating movement to the vertical drive wheels 6 to mobilize the mobile platform 1 along the parallel supports 2. The gearbox gears 19 is located on top of a vertical extension 21 of the front part 3a of the base 3.
    Thus, end sections of the two telescopic axes 18 are coupled in holes in the gearbox 19, while other end sections of said telescopic axes 18 are coupled in other through holes of two corner extensions 22 in which they are coupled. the vertical drive wheels 6; also incorporating two other corner extensions 22 to couple the other two vertical wheels 6 ’pairs. The rear part 3b of the base 3 includes an additional vertical extension 23 integral with the rear part 3b of the base 3, where said additional vertical extension 23 has another through hole that constitutes an additional support for one of the two telescopic axes 18.

    The four corner extensions 22 are in solidarity with the cross sections of the two parts 3a, 3b of the base 3, where the four vertical wheels 6, 6 'protrude outward and also said vertical wheels 6, 6' are located above said base 3.
    The transmission device 44 is complemented by a locking device 45 which must be previously manipulated each time the mobile platform 1 is to be moved along the two parallel parallel supports 2, so it is necessary to manually maintain the unlocking during the movement of the mobile platform 1.
    Said locking device 45 comprises an annular body 24 integral with one of the telescopic axes 18 located next to the additional vertical extension 23, wherein said annular body 24 has radial perforations 24a associated with a coupling rod 25 located and guided in a housing. 25 'integral to the additional vertical extension 23. Within said housing 25' a spring 27 is also located tending to move the coupling rod 25 towards an anchoring position in which said coupling rod 25 is inserted into one of the holes radial 24a of the annular body 24 to block the transmission device and therefore maintain in a static position the assembly of the mobile platform 1, although the parallel supports 2 are placed in an inclined plane.
    Thus, in order to move the mobile platform 1 with the manipulation of the transmission device 44, it is first necessary to release the locking device 45. For this purpose, it is necessary to step on a pedal 26 of the blocking device 45 against the resistance of the spring 27 while keeping the tread on the pedal 26. In this situation, when the pedal is stopped on said pedal 26, the locking device 45 recovers its resting position in which the coupling rod 25 is inserted into one of the radial holes 24a of the annular body 24 by the action of the spring 27.
    The mobile platform 1 includes anchoring devices 46 that ensures its connection to the parallel supports 2 during use. Said anchoring devices 46 comprise angular claws 28 that articulate in upper appendages 29 integral with the four corner extensions 22, where said claws have first vertical branches 28a with ends through which they articulate in the aforementioned upper appendages 29 and second ones. horizontal branches 28b with end sections facing upper collateral ribs 2b of the parallel supports that

    They have some steps to prevent the extraction of the mobile platform 1 upwards.
    The anchoring device 46 is complemented by tilting bolts 30 which ensure an active anchoring position of the angle claws 28. Said tilting bolts 30 articulate at the front ends at lower appendages 31 integral with the base 3 below the corner extensions. 22, while other rear ends opposite the previous ones are faced with the vertical branches 28a of the angular claws 28.
    When the angular claws 28 are in the anchoring position, said angular claws 28 are supported against the rear ends of the tilting bolts 30 located in a horizontal position resting on fixed stops 32.
    On the other hand, when the angular claws 28 are in an inactive position, the tilting bolts 30 are not in contact with the angular claws 28, but said tilting bolts 30 are folded in a position away from the angular claws 28. In this situation, the The weight of the angular claws 28 causes these to swing downwards, passively placing themselves in an unlocked position where the assembly / disassembly of the mobile platform 1 is possible.
    The mobile platform 1 of the invention includes stability devices 47 that prevent the pitching of the mobile platform 1 during use and are located in correspondence with the four corner extensions 22. Said stability devices 47 comprise adjustable axial dampers 33 including horizontal wheels 34 that contact the lateral supports with internal lateral faces 2. In the invention shown in the figures, they are internal lateral faces of the collateral ribs 2b of the parallel supports 2.
    Said axial dampers 33 comprise rods with end heads 35 in which the horizontal wheels 34 are coupled, wherein said rods are associated with springs housed within housings.
    The mobile platform 1 of the invention includes a fencing structure 48 that is fixed to the perimeter of the base 3 and also to the four corner extensions 22 that are part

For this, two opposing sides of the fence structure 48 comprise telescopic couplings between horizontal tubes of said fence structure 48.
    On one side of the fencing structure 48 there is a first access hole for the operators that can be closed by means of two facing sliding doors 36 that are coupled, by means of a telescopic connection, to collateral parts 37 of the fencing structure 48 fixed to two corner extensions 22 located on the same side. Said coupling is carried out by means of pairs of horizontal tubes that are part of the two sliding doors 36, where said horizontal tubes are inserted and glided into other horizontal tubes of the collateral parts 37. The anchoring of these two facing sliding doors 36 is secured by a folding bolt that fits into a complementary hole.
    The side where the two sliding doors 36 are opposite is the side where the two telescopic axes 18 transmit the rotating movement to the two vertical tractor wheels 6; where on this side of the telescopic axes 18, the fencing structure 48 includes a vertical tubular bar 38, inside which an extension of the upper crank 20 hovering above the fencing structure 48 is housed.
    The fencing structure 48 includes a hinged door 39 located on the side where the lower crank 14 is used to regulate the width of the mobile platform 1. The anchor of this hinged door 39 is also secured by a hinged bolt that is It fits in a complementary hole. Said swing door 39 articulates in one of the corner extensions 22 of the base.
