Abstract

The invention relates to the mining industry and improves the adaptability of the lining to the curvature of the contour of the workings. For this, the outer section base 31 is provided with windows 32 located between the hydro-resistant (HS) 20 outer sections, in which the inner 33 HS is installed. sections. In this case, the HS .20 is made with upper and lower cylinders. The overlap of the outer section is connected to HS 20 by clamps. The upper ones are made with longitudinal guides and fixed to the rods of the HS 20. The lower clamps are fixed to the upper cylinders. The overlaps are connected with expansion levers, which are fixed at one end in the lower clamps and - beams - in the upper clamps. The overlaps are made with longitudinal grooves 39 in which power elements are placed with the possibility of reciprocating movement — slides 40. On them are fixed the end portions of the leaf springs 41, the outermost of which are fixed at the ends of the overlaps. The springs carry support tops 42, interacting with top Kami 43 ground rails. The thrust force of the inner section and the elastic force of the springs 41 are automatically distributed between the tops 43 and 42 evenly due to different degrees of deflection of the springs 41. As a result, the sliders 40 adapt to the curvatures of the production contour and drift lines. 5 il. c (L 7 // L V% //// 7/36 31 ////// / X / /// / L //. // L / 32 Thebes 1 7 / /// / L 1 about 32 th J7

The invention relates to the mining industry, predominantly angular, and can be used in fasteners designed to fasten the roof and maintain elements of the drift in the areas of interface of the lavas with adjacent workings of arched and trapezoidal sections.

The purpose of the invention is to improve the adaptability to the curvature of the contour of workings.

FIG. Figure 1 shows the mating support, general view, frontal projection; in fig. 2 - the same, horizontal projection; FIG. 3 is a view A of FIG. one; in fig. The 4th version of the support mating for the arch of the arched section j in FIG. 5 - diagram of the hydraulic rack with the upper and lower cylinders.

The mating support includes a berm 1 and two drift sections - an outer 2 and an inner 3. A top 4 overlaps the berm section; Lena on traverses 5 and interact with interconnected traverses themselves 6, upper kam 7 overlapping the end section 8 of the lining support. The tops 4 and the traverse 5 are pushed into the roof by hydraulic posts 9, and the tops 7 and Traverses 6 by the hydraulic legs of the end section of the front support (not shown). The berm section 1 is moved by a hydraulic jack 10, which is fixed on the base 11. If necessary, it moves together with the mounting table 12 of the drive head 13 of the front conveyor 14. The barrier plate 15 is installed on the cross-pieces 5 of the berm section 1, which is spread into the roof rock by a system of expansion arms 16. Breeds of undermining soil are kept from collapsing flap 17 ..

The screw sections of the mating are represented by the outer section 2 and the inner section 3, while the overlap 18 of the outer section is made of two beams, and the inner section is made of a single beam 19. The hydraulic legs 20 of the outer section are made with the upper 21 and lower 22 cylinders, in which The pistons 23 and 24 are mounted on a common rod 25. The overlap 18 of the outer section 2 is connected to the spacer arms 26, which are fixed at one end in the lower collars 27 and beams in the upper collars 28. The upper collars 28 are provided with longitudinal guides 29 and installed on

the rods 25 are hydraulically mounted 20, and the lower clamps 30 are connected to the upper cylinders 21 of these hydraulics and can be moved up and down the stem 25. The base 31 of the outer section 2 is provided with windows 32 located between the hydraulics 20 of the outer section, in which the hydraulics 33 of the inner section 3 are installed, the shield 34 is hingedly hinged in the supports 35 of the upper clamps 28 and the eyes 36 of the base 31 of the outer section 2. Sliding sections 2 and 3 implementation with hydraulic jacks 37 and 38, us-. On the base 31 and on the overlap 19, respectively. In the longitudinal grooves 39 of the overlaps 18 and 19 are placed with the possibility of reciprocating movement. Power elements - slides 40, on which are attached the end parts of the sheet springs 41, the outermost of which are fixed at the ends of the overlaps 18 and 19 Sheet prues 7}; yin carry support tops 42, which interact with the top cdmi 43 of the lintel and are connected to each other and with the ends of the overlaps by the hinge links 44.

The support works as follows.

The support is spread into the roof .and the soil. The working fluid from the pressure line enters the cavities P and N of the hydraulic rails 20 "For shifting the lining unloads the inner section 3. At the same time, the overlap 19 of this section rests on the longitudinal guides 29. The racks 33 are reduced. The hydraulic jack 38 expands and moves the section in the direction of advance of the bottom step of the advance. The overlap 19 is guided by the longitudinal guides 29 in a predetermined direction, and the hydraulics 33 by the side walls of the windows 32. After the movement, section 3 is spread to the roof and the ground. During the thrust, the support heads 42 come into contact with the tops 43 of the lintel alternately and as a result of the increasing effort of the thrust, the tops of the tops that came in contact with the heads of the drift supports, unclench the leaf springs interacting with them, which remove the leaf-springs of adjacent support tops, which did not come into contact with the roofing supports, for example, by the value of h before their contact. Further, the expansion of the section and the elastic forces of the leaf springs are automatically distributed evenly between all support tops and top liner due to the varying degree of deflection of the leaf springs, as a result of which the power elements are adapted to the curvature of the output contour and the lintel. After thrusting into the roof and soil of the inner section 3, they move the head 13 of the lateral conveyor 14, then unload and move the berm section 1 with the hydraulic jack 10, carrying the upper 4, resting on the tie rods 6 of the end section 8 of the lining support, bounding

the contour of the excavation and upper deck roof lining 43 occurs similarly to the described process of laying into the roof and soil of the inner section 3.

Further, the work cycle of the support mating is repeated.
