Abstract
The utility model belongs to underground coal mining devices for coal mines, and particularly relates to a demising buffering and power-absorbing single hydraulic bracket device. The device comprises two single hydraulic brackets (2), wherein a channel steel upper bracket (1) is fixedly connected with the upper ends of the two single hydraulic brackets (2), demising power-absorbing bases (4) are connected with the lower surfaces of the two single hydraulic brackets (2) through rivets (3), the lower surfaces of the demising power-absorbing bases (4) are fixedly welded on the upper surface of a base plate (6), each demising power-absorbing base (4) is formed in such a manner that foam plates (4-1) are mounted on the upper and the lower surfaces of an aluminum base (4-2) in the middle of the interior of a base box (7), and a connecting body (5) is arranged at the periphery in the middle of each demising buffering base box (7). The demising buffering and power-absorbing single hydraulic bracket device has the advantages of simple structure, convenience in assembly and disassembly, high reusability, and favorable buffering and power-absorbing functions, and can effectively reduce the impact load, weaken the destructiveness of rock burst, and effectively guarantee the safety of mines and workers.
Description
Technical field
The utility model belongs to the colliery down-hole coal excavation apparatus, particularly a kind of buffering energy-absorbing monomer hydraulic pressure holder device of stepping down.
Background technology
The China's coal-mine resource exploitation turns to the deep gradually, and the bump frequency and the extent of injury sharply increase, and the tunnel of causing caves in, supporting and protection structure is destroyed and personnel casualty accidents is on the rise.In the last few years, the laneway support method of formation mainly comprised active support and passive protecting, and the monomer hydraulic support is applied to coal mine roadway as emerging passive protecting mode and has obtained better development, has also obtained good supporting effect.Though monomer hydraulic support support strength height allows certain distortion under the action of static load,, discharge rate is slow under percussion, deflection is little, and opposing shock loading ability very easily causes support tilt, destruction.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, a kind of dress is provided, tears open conveniently, and reusability is strong, can effectively reduce the buffering energy-absorbing monomer hydraulic pressure holder device of stepping down of shock loading.
The technical scheme that the utility model technical solution problem adopts is: the buffering energy-absorbing monomer hydraulic pressure holder device of stepping down comprises the monomer hydraulic support, be characterized in fixedly connected channel-section steel upper bracket in the upper end of two monomer hydraulic supports, below two monomer hydraulic supports, connect the energy-absorbing base of stepping down with rivet, step down and be weldingly fixed on above the backing plate below the energy-absorbing base, the energy-absorbing base of stepping down is the aluminium base cystosepiment of adorning up and down middle in the base box, allows place, the middle outer of bit buffering base box establish connector.
The beneficial effects of the utility model are: the buffering energy-absorbing monomer hydraulic pressure holder device of stepping down is simple in structure, adorns, tears open conveniently, and reusability is strong, have good buffering and energy-absorbing function, can effectively reduce shock loading, weaken the bump destructiveness, effectively guarantee mine and workman's safety.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is the buffering energy-absorbing monomer hydraulic pressure holder device structure chart of stepping down.
Among the figure, 1-channel-section steel upper bracket; 2-monomer hydraulic support; The 3-rivet; The 4-energy-absorbing base of stepping down; The 4-1-cystosepiment; 4-2-is aluminium base; The 5-connector; The 6-backing plate; 7-base box;
The specific embodiment
With reference to accompanying drawing 1, the buffering energy-absorbing monomer hydraulic pressure holder device of stepping down is applied to coal mine rock burst mine laneway and ahead work face supporting, is that upper end at two monomer hydraulic supports 2 is 1 fixedly connected and closely be connected with coal and rock on channel-section steel.The lower end of monomer hydraulic support 2 fixes on the energy-absorbing base 4 of stepping down with rivet 3 usefulness, the energy-absorbing base 4 lower ends welding of stepping down be fastened on backing plate 6 above, wholely form a suspension device, can effectively reduce bump, weaken the bump destructiveness.The energy-absorbing base 4 of stepping down is that aluminium base 4-2 is established in the centre in base box 7, and upper and lower is cystosepiment 4-1, establishes connector 5 on the base box 7 outside upper and lower cystosepiment 4-1, makes it carrying ground and presses impact energy.
Claims (1)
1. buffering energy-absorbing monomer hydraulic pressure holder device of stepping down, comprise monomer hydraulic support (2), it is characterized in that at the fixedly connected channel-section steel upper bracket in the upper end of two monomer hydraulic supports (2) (1), below two monomer hydraulic supports (2), connect the energy-absorbing base (4) of stepping down with rivet (3), step down and be weldingly fixed on above the backing plate (6) below the energy-absorbing base (4), the energy-absorbing base (4) of stepping down is that aluminium base (4-2) middle in base box (7) adorns cystosepiment (4-1) up and down, allows place, the middle outer of bit buffering base box (7) establish connector (5).
