Abstract
The utility model discloses an energy-absorption self-moving hydraulic support which comprises a metal hinge beam, a plurality of single hydraulic support bodies, a movable base, a dual-direction jack and a scrapper. The metal hinge beam is formed by a plurality of sections of movable transverse beams in a head-to-tail connection mode, the single hydraulic support bodies are fixedly connected with the metal hinge beam through clamping sleeves, energy-absorption bases are arranged at the bottoms of the single hydraulic support bodies and fixed on the movable base, the back end of the dual-direction jack is fixed to the movable base through a hinge base, and the front end of the dual-direction jack is connected with the scrapper. The energy-absorption self-moving hydraulic support is simple in structure and high in repeated using performance, the energy-absorption self-moving hydraulic support can be directly and wholly pushed forwards under the effect force of the dual-direction jack without manual disassembling after one working face is exploited, time and labor can be saved, the working efficiency and the coal production can be improved, the energy-absorption bases can have the good buffer effect and the good energy-absorption effect, impulse loads can be effectively reduced, the rock burst destroy degree can be weakened, and safety of mines and workers can be effectively guaranteed.
Description
Technical field
The utility model relates to a kind of hydraulic support, and specifically a kind of energy-absorbing is from mobile hydraulic support.
Background technology
Monomer hydraulic bracket is widely applied in the seam mining scope of operation of coal mine roadway as emerging passive protecting mode, continuous exploitation due to coal seam, hydraulic support also will move thereupon, traditional hydraulic support volume is large, quality weight, in dismounting, installation process, a large amount of manpowers and time have been wasted, larger to Influence of production, the hydraulic support of light material cannot well complete support work again, under percussion, discharge rate is slow, deflection is little, opposing shock loading ability, very easily cause support tilt, destruction, security performance can not get ensureing.
Summary of the invention
The purpose of this utility model be to provide a kind of can automatic moving, reusability is strong, the energy-absorbing that can effectively reduce shock loading is from mobile hydraulic support, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of energy-absorbing is from mobile hydraulic support, comprise metal hinge beam, a plurality of monomer hydraulic brackets, movable base, two-way jack and scrapper conveyor, described metal hinge beam is formed by connecting from beginning to end by the crossbeam of multi-segment activity, described monomer hydraulic bracket is fixedly connected with metal hinge beam by cutting ferrule, the bottom of described monomer hydraulic bracket is provided with energy-absorbing base, described energy-absorbing base comprises base box, foam buffer board and aluminium sheet, the upper and lower both sides of described aluminium sheet all arrange foam buffer board, described foam buffer board and aluminium sheet are arranged in base box, described base box both sides external arranges connector, described energy-absorbing base is fixed on movable base, the rear end of described two-way jack is fixed on movable base by hinge seat, the front end of described two-way jack is connected with scrapper conveyor.
As the utility model scheme further: described monomer hydraulic bracket is connected with energy-absorbing base by rivet.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, and reusability is strong, can be after completing the exploitation of a work plane, without artificial handling, utilize the active force of two-way jack, directly integral body is pushed ahead, time saving and energy saving, improved working efficiency and output of coal, energy-absorbing base has good buffering and energy-absorbing function, effectively reduces shock loading, weaken bump destructiveness, effectively guarantee mine and workman's safety.
