Description
Technical field
The utility model belongs to underground coal mine support apparatus, particularly a kind of spring rod-pulling type hydraulic support anti-impact device.
Background technology
In pit mining process, bump is very large, and presses to force direction changeable at top, tunnel; under the protection of hydraulic support; the destruction of bump to tunnel can be alleviated, although hydraulic support all with safety valve as overvoltage protection, hydraulic support is due to directly stressed; and Impact direction and stress point alter a great deal; after there is bump suddenly, safety valve protective capability is limited, generally after a work period; badly broken, brings about great losses to safety and economy.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, and provide a kind of structure simple, supporting intensity is large, safe and reliable spring rod-pulling type hydraulic support anti-impact device.
The technical scheme that the utility model technical solution problem adopts is: spring rod-pulling type hydraulic support anti-impact device comprises base, hydraulic vertical prop, column control valve, back timber, be characterized in the base inside two hydraulic vertical props being fixedly equipped with respectively two pull bar housing mount pads, pull bar Connection Block is fixedly equipped with respectively in the inner side of two hydraulic vertical props, pull bar housing mount pad is hinged the hinge axis hole of pull bar housing engaging lug with bearing pin, pull bar housing engaging lug is fixedly connected with pull bar housing, pull bar housing upper end is fixed welding case lid is housed, in pull bar housing, spring is equipped with respectively in below, above spring, pull bar is equipped with in activity respectively, pull bar movable upper end is through case lid, pull bar upper end is provided with pull bar engaging lug, be hinged with bearing pin between pull bar engaging lug and pull bar Connection Block.
The beneficial effects of the utility model are: spring rod-pulling type hydraulic support anti-impact device structure is simple, safe and reliable, simple and easy to do, economical and practical, supporting intensity is large, time saving and energy saving, be specially adapted to bump frequent operation district, down-hole, the effective reaction time is provided to operating personnel.
Accompanying drawing explanation
Illustrate with embodiment below in conjunction with accompanying drawing.
Fig. 1 is spring rod-pulling type hydraulic support anti-impact device and hydraulic vertical prop installation form figure.
Fig. 2 is spring rod-pulling type hydraulic support anti-impact device structure chart in Fig. 1.
In figure, 1-back timber; 2-hydraulic vertical prop; 2-1-pull bar Connection Block; 3-column control valve; 4-base; 5-pull bar housing; 5-1-pull bar engaging lug; 5-2-pull bar; 5-3-pull bar housing engaging lug; 5-4-spring; 5-5-case lid; 6-pull bar housing mount pad; 7-bearing pin.
Detailed description of the invention
Embodiment, with reference to accompanying drawing 1,2, the arranged on left and right sides above of the base 4 of spring rod-pulling type hydraulic support anti-impact device is fixedly equipped with a hydraulic vertical prop 2 respectively, the lateral surface of two hydraulic vertical props 2 is fixedly equipped with respectively between column control valve 3, two hydraulic vertical prop 2 upper ends and is fixedly connected with a back timber 1.Base 4 inside two hydraulic vertical props 2 is fixedly equipped with respectively two pull bar housing mount pads 6, the hinge axis hole of pull bar housing engaging lug 5-3 that pull bar housing mount pad 6 is articulated and connected with bearing pin 7, pull bar housing engaging lug 5-3 is fixedly connected with pull bar housing 5.Pull bar housing 5 upper end is fixed welding case lid 5-5 is housed, in pull bar housing 5, below is equipped with spring 5-4 respectively, above spring 5-4, pull bar 5-2 is equipped with in activity respectively, pull bar 5-2 movable upper end is through case lid 5-5, pull bar 5-2 upper end is provided with pull bar engaging lug 5-1, is hinged between pull bar engaging lug 5-1 and pull bar Connection Block 2-1 with bearing pin 7.
The operation principle of spring rod-pulling type hydraulic support anti-impact device is: pull bar housing mount pad 6 is placed on the base 4 inside hydraulic vertical prop 2 respectively, pull bar Connection Block 2-1 is separately fixed on the medial surface of hydraulic vertical prop 2, is all hinged with bearing pin 7 between pull bar engaging lug 5-1 and pull bar Connection Block 2-1, between pull bar housing mount pad 6 and pull bar housing engaging lug 5-3.When bump arrives out of the blue, make hydraulic vertical prop 2 can have the swing of a stride degree within the scope of spring 5-4 predetermined elastic force, when bump comes, spring rod-pulling type hydraulic support anti-impact device can make hydraulic support tilt to release the pressure by spring 5-4 and pull bar 5-2 instantaneously after stressed, the equipment extent of damage of making reaches minimum, boosted by hydraulic vertical prop 2 after pressure and the stable back timber 1 that connects, simultaneously due to flexible release pressure, provided to operating personnel the effective reaction time.
