Description
Technical field
The invention belongs to the mine safety support apparatus, particularly a kind of fast wave eliminating/energy dissipating/cushioning device for mining.
Background technology
Bump is one of main dynamic disaster of mining engineering, the increase that day by day becomes along with the mining mineral resource degree of depth, the bump generation frequency and destructiveness are also further strong, the a large amount of impact energy of abrupt release when occuring to impact, cause tunnel wall caving, roof fall and collapse, the whole unstability of supporting and protection structure, plant equipment is tumbled, is destroyed, even the accident such as casualties, have a strong impact on mineral resources safe working and staff's life security.
Mining support equipment commonly used has timbering, steel bracket, U-shaped steel bracket, hydraulic prop and hydraulic support etc., and all take rigid protection as main, safety factor is very high under the action of static load, substantially can guarantee the safety requirements of support system in the mine.But, in a single day bump happens suddenly in the ore deposit, flexibly pressure energy moment of country rock body inner accumulated, the form with shock wave discharged, be in rigid protection body under the stable state with violent percussion to former, cause support apparatus generation sudden destroying, such as, hydraulic support can cause hydraulic valve to be washed out owing to release is untimely, and hydraulic support is killed.
Existing snubber is divided into fluid pressure buffering and elastic buffer two kinds basically, shock-absorbing capacity and effect are relatively good, but it is not very good using in mine support, bump is same often with the high speed deformation failure of rock mass what discharge a large amount of impact energys, it is fast that this requires snubber to have reaction speed, the strong characteristics of ability of the large and impact-absorbing energy of deflection, and elastic buffer is that the elastic potential energy that impact energy is converted into self can't be laid down energy, oil buffer is facing under the high speed impact and can because release damages not as good as causing, both can not effectively solve the serious problems that bump brings.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, providing a kind of can subdue shock wave fast, absorbs the fast wave eliminating/energy dissipating/cushioning device for mining of a large amount of bumps energy.
The technical scheme that technical solution problem of the present invention adopts is: fast wave eliminating/energy dissipating/cushioning device for mining comprises the top rigid sleeve, the bottom rigid sleeve, be characterized in being connected and fixed an outside bottom in the bottom thread of bottom rigid sleeve, externally in the bottom rigid sleeve above the bottom columniform compressibility energy-absorbing material is housed, be provided with the gap between energy-absorbing material and the bottom rigid sleeve inwall, dress internal rigid bottom on energy-absorbing material, a top rigid sleeve is threaded above the internal rigid bottom, top rigid sleeve outer wall in upper end thickening place of corresponding bottom rigid sleeve is provided with trapezoidal groove, at corresponding top rigid sleeve outer wall upper trapezoid groove, clamp four with the pin card of shape at the bottom rigid sleeve, pin card is less than 90 degree annulars, the medial surface of annulus is provided with trapezoid boss, in the trapezoidal groove on the rigid sleeve outer wall of trapezoid boss embedding top, the annulus both ends of the surface are equipped with the adpting flange boss, establish screw hole on the adpting flange boss, every adjacent two adpting flange boss all are connected with wing nut with screw rod, at the screw jacket shock mount.
The invention has the beneficial effects as follows: fast wave eliminating/energy dissipating/cushioning device for mining is when occuring for bump; the characteristics that large energy discharges and rock mass is out of shape at a high speed; utilize the larger plastic compression deformation of foamed alloy material based on the flexing principle; the characteristics of higher compressive strength and good good impact toughness; in addition organic cooperation of rigid material; the function of fast wave-damping power consumption under effective performance of the rigid protection ability under the realization action of static load and the percussion; reaching the buffer protection function to the miscellaneous equipment in the support system, thereby farthest avoid machinery production device damage and staff's casualty accident to occur.
