A MECHANIZED STRIP WITH APPLICATION, containing overlapping and ///.//// upper tops of the outer and inner sections, hydraulic racks and soil stripping mechanisms, characterized in that, in order to increase the reliability of the lining in operation by preventing it from sinking For the influence of shtyb, the mechanisms for stripping the soil are made in the form of semirings spanning the hydraulics, connected with bolts and eyes, to which the hinges are attached at one end of the flap, connected with each other by a force element, and the stripping mechanisms chvy mounted for movement along a hydraulic legs. /. u g 20

Description

The invention relates to mining and can be used in mechanized crepe mating in coal mining. The purpose of the invention is to increase the reliability of the lining in operation by preventing its sagging and shifting back due to the influence of the tip. FIG. 1 shows the lining, side view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B (rotated 90 °) in FIG. one; in fig. 4-node in FIG. one; in fig. 5 shows a section B-B in FIG. four; in fig. 6 - position of the loaded section before thrusting the hydrostalk; in fig. 7 - introduction to the piece cushion; in fig. 8 - soil stripping; in fig. 9 - lining in development, general view. The mechanized lining of the mating contains overlaps 1, hydraulic legs with support shoes 3, mechanisms 4 of soil stripping fixed on hydraulic legs 2. The covering is made of external 5 and internal 6 sections having top 7 and transverse beams 8 with glasses 9 in which are installed hydraulics 2. The support bolts are moved by means of hydraulic cylinders 10. The soil stripping mechanism 4 is made in the form of a slider 11, which encloses the hydraulic column 2 with the ability to move along a stand, two rock 12, interconnected by springs 13 and Hydraulic pillars 3 are mounted on supporting shoes 3. Slider 11 consists of two half-rings 14 interconnected by bolts 15. Semi-rings 14 have openings 16 for each of the axles 17 for swiveling the flaps 12 with the slide 11. There are elastic between the half-rings 1 of the slider 11 elements 18. Mechanism 4 has an end 19, and glass 9 an end 20. The support works as follows. When moving the supports, the hydraulic legs of the inner section are unloaded until the top 7 is lowered onto the crossbeams 8 and the supporting towers of the three hydraulic legs. stripping mechanisms 4 ochvy not otorvuts from the soil. In this case, the hydraulics of the outer section are under thrust. By switching on the hydraulic cylinders 10, the inner section is shifted. Then, the inner section is spread. After that, in the same way, the hydraulics of the outer section are unloaded, pulled up to the inner section, and expanded. At the same time, at first, the hydraulics using the soil clearing mechanisms 4 with folded doors 12 are folded into the bayonet pad, then they are cleared by pushing the shutter 12 apart with the support shoe 3 of the descending pillars. The insertion force of mechanisms 4 is adjusted by means of elastic elements 18, which allow to calibrate the pressing of half-rings 14 of the slide 11 in order first to introduce mechanism 4 into the bayonet until the moment 4 touches the solid soil mechanisms 4, and then under the continued lowering of hydro-racks 2 to open the valves 12 mechanism 4 lowering support shoes 3. Simultaneously with lowering the shoes 3 shutters 12, the bayonet cushion extends under each hydraulic rack. In this case, the mechanisms 4, having overcome the force of the springs, 18, climb up the hydraulic legs 2 until the support shoes 3 gain solid ground and complete lining of the support sections is completed. When moving the mating, it is necessary to raise the hydraulic legs of one of the lining sections. In the process of lifting, the hydraulic rails 4 together with the hydraulic rails 2 rise up to the stop with the ends of 20 cups 9 at the ends of the 19 meanism 4, while the movement of the mechanisms 4 stops and the cylinders of the pillars 2 with support shoes 3 continue to move upward inside the sliders 11 until the shutters 12 of the mechanism 4 under the action of the springs 13 are folded, retracted. The control of the support is carried out from the control panel located in the safe zone.
