Description
Technical field
This utility model belongs to coal mine production safety suspension device, more particularly to a kind of high-bearing capacity and anti-shock loading
Energy absorption device.
Background technology
With being gradually increased for mine resources mining depth, bump supporting roadway surrounding rock stably becomes urgent need to resolve
A difficult problem, Chinese scholars have studied some support method for different rock properties, and conventional supporting includes：Anchor pole, anchor net,
The support pattern such as anchor cable, U-shaped steel and hydraulic prop and comprehensive mining hydraulic bracket.Above support pattern is improving country rock and is propping up
Watch box intensity aspect plays a good role, and can preferably delay bump to occur, but impact but can not subtract after occurring
Light or reduction dynamic impact problem disaster, most probably causes bigger disaster to occur.
Existing R-F-R supporting construction with certain energy-absorbing, shock-absorbing function, but due to porous metals material itself
The characteristics of, the destruction for energy-absorbing material shape occur is easy in installation process, cause when impacting next, energy-absorbing material can not be inhaled
Receive enough shock loadings, it is impossible to realize expected energy-absorbing effect, jeopardize tunnel safety.
The content of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, there is provided a kind of simple structure, it is easy for installation, safety can
The high-bearing capacity for leaning on and the energy absorption device of anti-shock loading.
The present invention solves the technical scheme of technical problem employing：The energy absorption device of high-bearing capacity and anti-shock loading includes
Gray iron, is characterized in being provided with screw boss on circular cylinder base wall, sets in cylinder base wall and screw boss
There is hydraulic medium inlet, the threaded connection protection nut in screw boss, and sealed with sealing member two, in the outer of protection nut
Inside and outside correspondence sets a triangle weakness annular groove on end face, in cylinder body built with porous or the energy-absorbing material of reductus shape, in cylinder
In vivo hydraulically full medium, fills cylinder cap above energy-absorbing material and liquid medium, is sealed with sealing member one between cylinder cap and cylinder body,
Air bleeding valve installing hole is provided with the center of cylinder cap, the threaded connection in air bleeding valve installing hole is mounted in air bleeding valve, and air bleeding valve is installed
The connection of hole lower end is provided with steam vent, and in the center of air bleeding valve valve air vent one is provided with, and sets the lower section of valve air vent one is oblique
There are several valve air vents two, valve air vent two is connected with air bleeding valve installing hole, and the cone angle below air bleeding valve is inserted in steam vent,
Screwed holes and cylinder body energy-absorbing are installed away from being respectively provided with four cylinder cap energy absorption devices on the lower surface of the upper surface of cylinder cap and cylinder body
Device installs screwed hole.
The beneficial effects of the utility model are：The energy absorption device of high-bearing capacity and anti-shock loading may be mounted at supporting dress
At the top board put or at base plate, when no impact load or less impact load, there is very little in the hydraulic medium in cylinder body
Decrement can just provide sufficiently large support force, play support action, when there is impact load, the protection nut on cylinder body
Brittle fracture can occur at weak annular groove, the hydraulic medium in cylinder body is pressurized to be unloaded from liquid medium inlet to outside cylinder body
Go out, absorb substantial amounts of energy, while cylinder cap can be descending along cylinder body under substantial load effect and compresses energy-absorbing material, make energy-absorbing material
Material is deformed, and dissipate big energy, after impact, can disassemble energy-absorbing material, is reinstalled energy-absorbing material, repeats
Use, supporting effect is good, protect mine support device, save support cost.
