Abstract
The utility model relates to the technical field of hydraulic supports, in particular to a four-post-supported double pendulum rod hydraulic support. A pushing device (8) is arranged on a base (7); the base (7) is connected with a top beam (1) through four upright posts (3); a top beam side protecting plate (2) is arranged on the top beam (1); a slant pulling jack (6) is arranged on the middle part of the base (7); an upper pendulum rod (4) and a lower pendulum rod (5) which are connected with the tail end of the top beam (1) and the upper end of the base (7) respectively are arranged on the middle upper part of the back side upright post (3); and a rock baffling plate (9) is arranged at the tail end of the top beam (1). The four-post-supported double pendulum rod hydraulic support has the characteristics of simple structure, light weight, high stability, low requirements on a top plate and a bottom plate, convenience in transportation and installation, flexible operation, low cost and the like.
Description
Technical field:
The utility model relates to the hydraulic support technical field, is specifically related to a kind of four post brace type double pendulum bar hydraulic supports.
Background technology:
Existing hydraulic support all things considered mainly comprises two big types: suspension moving hydraulic support, comprehensive mining hydraulic bracket.
Suspended type hydraulic support has advantages such as volume is little, in light weight, easy transportation and installation, flexible movements, but owing to is connected the overall operation face through joist between back timber and the back timber and fuses, has promptly increased the complexity of structure, and top board is required height, poor stability; Because column directly acts on base plate, base plate is required height again, be prone to prick at the end, pushing and sliding move the frame inconvenience;
Fully mechanized mining supporter has overcome the above-mentioned shortcoming of integral top beam combined suspension moving support, but have that volume is big, weight is big, the transportation difficult installation, to defectives such as mine laneway requirement height, cost height.Therefore in the actual use of mine, particularly in medium and small colliery and old mine, press for a kind of novel support apparatus that has above-mentioned two kinds of hydraulic support advantages simultaneously.
The utility model content:
The purpose of the utility model provides four post brace type double pendulum bar hydraulic supports, and it is simple in structure, in light weight, good stability, roof and floor is required characteristics such as low, easy transportation and installation, flexible movements, cost are low.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises back timber 1, back timber side guard board 2, column 3, upper pendulum bar 4, draft link 5, tiltedly draws jack 6, base 7, push unit 8 and waste rock board 9; Base 7 is provided with push unit 8; Be connected with back timber 1 through four root posts 3 on the base 7; Back timber 1 is provided with back timber side guard board 2; Base 7 middle parts are provided with and tiltedly draw jack 6, and rear side column 3 middle and upper parts are provided with and the back timber 1 terminal upper pendulum bar 4 and draft link 5 that is connected respectively with base 7 upper ends, and the end of back timber 1 is provided with waste rock board 9.
The utility model is got its chief, is gone its shortage to cantilever support and fully mechanized mining supporter pluses and minuses separately, has characteristics such as simple in structure, in light weight, good stability,, easy transportation and installation low to the roof and floor requirement, flexible movements, cost are low.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
Referring to Fig. 1-2, this specific embodiment is to adopt following technical scheme: it comprises back timber 1, back timber side guard board 2, column 3, upper pendulum bar 4, draft link 5, tiltedly draws jack 6, base 7, push unit 8 and waste rock board 9; Base 7 is provided with push unit 8; Be connected with back timber 1 through four root posts 3 on the base 7; Back timber 1 is provided with back timber side guard board 2; Base 7 middle parts are provided with and tiltedly draw jack 6, and rear side column 3 middle and upper parts are provided with and the back timber 1 terminal upper pendulum bar 4 and draft link 5 that is connected respectively with base 7 upper ends, and the end of back timber 1 is provided with waste rock board 9.
Described back timber 1 is a case structure respectively with base 7, is the main pressure-containing member of support, and back timber 1 bears the pressure from top board.The middle upright supports of leaning on, power is delivered on the base 7 the most at last.Column 3 stretches out and drives back timber 1 and move upward during work, and upper pendulum bar 4, draft link 5 rotate along hinge separately, thereby adjustment tiltedly draws jack 6 to guarantee the tram of back timbers 1, if be necessary to adjust back timber side guard board 2, makes keeping parallelism between each support.When back timber 1 with after top board contacts, column 3 pressurizes, support reaches setting load.This moment column 3 and tiltedly draw jack 6 acting in conjunction roof supportings; Its working resistance sum is greater than four post working resistances; The double-lever mechanism that upper pendulum bar 4, draft link 5 are formed overcomes the lateral force and the torsion of top board and base generation; Make support keep stable, waste rock board 9 prevents that the rear portion spoil from scurrying in the support.After coal-winning machine was adopted a step pitch, thrust gear 8 work promoted work plane conveyer 1 reach among Fig. 2; After step pitch of work plane conveyer 1 reach; Column 3 is regained, and adjustment tiltedly draws jack 6 to make back timber break away from top board, and the passing jack of thrust gear is regained; Step pitch of pulling support reach is accomplished an operation cycle.So repeatedly, at a high speed, efficiently, the completion coal mining task of safety.
This specific embodiment is got its chief, is gone its shortage to cantilever support and fully mechanized mining supporter pluses and minuses separately, has characteristics such as simple in structure, in light weight, good stability,, easy transportation and installation low to the roof and floor requirement, flexible movements, cost are low.
