The technology used to drill the corridor workings requires manual execution of a series of works at height in the immediate vicinity. two faces of the excavation. These works are performed from demountable platforms placed on the pit spag. It is known from the CSM patent description. No. 121 098 working platform suspended on the arches of the excavation hatch. The disadvantage of this prop is the great laboriousness of its assembly and the difficulty of simultaneously carrying out other works from the pit of the excavation, because the sled bridge interferes with the passage of loaders, mine carts and other unzaidzen. Suspension of the platform on the support frames reduces the load-bearing capacity of the support, which is additionally loaded with the initial support near the front face, which in case of bad geological conditions poses a threat to the safe performance of mining works. The purpose of the invention is to enable safe execution of works at height by creating The construction of such a working platform that would eliminate the hitherto difficulties in assembly and, at the same time, would allow it to be adapted to the different heights of the excavations, as well as increase the strength of the final lining near the face of a pitted mine excavation. A further object of the invention is such a construction The construction of a platform which, having the above advantages, at the same time will not constitute an obstacle to the passage of loaders, mine carts and the movement of people employed in the vicinity. This aim has been achieved by means of the bridge which is the subject of the present invention. The essence of the invention consists in the fact that the bridge structure is a known stand that supports the canopy of the final support with any force, and the platform is mounted on the stand by means of rotating sleeves and joints, which has three degrees of freedom to change its position with respect to the stand. The subject of the invention is shown in an example of its implementation in the drawing, in which Fig. 1 shows a cross-section of the face of the excavation with an exemplary location of the working bridge in its various positions in a side view, figure, 2 view from above, showing the possibility of changing the position of the platform. As shown in the figure, the working platform consists of a telescopic stand 1 stretched between the pit floor and the canopy of the final support. Coaxially on the stand 1, rotating sleeves 2 and 3 are slidably supported, supported by ring stops 4 and 5, equipped with interlocking devices 6 for locking them against the stand 1. The platform 8 is connected to the rotating sleeve 2 by means of a joint 7. The platform 8 is equipped with articulations 9, which connect it to the pliers 10, articulated joints 11 with a rotating sleeve 3 based on a ring-shaped resistance 5. Rotary sleeves 2 and 3 mounted in rotation and slide on the stand 1 have retaining elements 12 protecting against undesirable rotation platform 8 relative to the stand 1. The above-described working platform can, for example, be used as shown below. In order to facilitate the description of the operation, the individual positions of the platform are marked with Roman numerals in the figures. Figures 1 and 2 show the position I with thick lines, in which the poist 8 'occupies the working position, from which a man can twist the casing locks and work related to the casing of this part of the pit. FIG. 2 shows the landing 8 in position II, formed by turning it through an angle of 90 °. From this position, work can be carried out on roof trimming, erecting a temporary cladding and drilling blast holes. the dashed lines in the figures 1 and 2 mark the position III, created by the further rotation of the platform 8, from which the works related to erecting the lining in the upper memories of the excavation are carried out. The broken lines in figure 2 are marked. position. IV of the platform 8, from which the works related to the repair of the casing, the suspension of the gill and pipelines are carried out. The dotted lines in Fig. 1 indicate the position V, in which by loosening the locking device 6 the resistance ring 5 has been moved along with rotating sleeve 3 to the upper position, as a result of which the platform 8 is turned with respect to the articulation 7 and the rod 10 in the articulated joints 9 and 11 is rotated in a vertical position and enables the passage of mining devices. Regardless of the above-mentioned positions of the platform 8, by loosening the locking devices 6 can be moved ring-shaped stops 4 and 5 with rotating sleeves 2 and 3 in relation to the stand 1 15 up or down and by re-jamming the locking devices 6 ', the platform 8 is set at any preset height with respect to the spag of the excavation. Any other position of the platform 8 20 is obtained by combining the possibility of its rotation and axial displacement in relation to the stand 1.
