Description
Technical field
The utility model belongs to the mine safety support apparatus, particularly a kind of mining fast wave-damping power consumption buffer.
Background technology
Bump is one of main dynamic disaster of mining engineering, the increase that becomes day by day along with the mining mineral resource degree of depth, the bump generation frequency and destructiveness are also strong further, the a large amount of impact energy of abrupt release when taking place 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 accident such as casualties, have a strong impact on mineral resources safe working and staff's life security.
Mining support apparatus commonly used has timbering, steel bracket, U shape steel bracket, hydraulic prop and hydraulic support etc., and all based on the rigidity supporting, safety factor is very high under the action of static load, can guarantee the safety requirements of support system in the mine substantially.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 rigidity prop under the stable state with violent percussion to former, cause support apparatus that unexpected unstable failure takes place, 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, this requires towards the utensil speed that responds fast, deflection is big and absorb the strong characteristics of ability of impact energy, 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 cause damaging because of release is too late, and the both can not solve bump effectively and bring serious problems.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, and providing a kind of can subdue shock wave fast, absorbs the mining fast wave-damping power consumption buffer of a large amount of bumps energy.
The technical scheme that the utility model technical solution problem adopts is: mining fast wave-damping power consumption buffer 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, on the rigid sleeve of bottom, clamp four pin cards with shape, the pin card is for spending annulars less than 90, 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 beneficial effects of the utility model are: mining fast wave-damping power consumption buffer is when taking place at bump; the characteristics that big energy discharges and rock mass is out of shape at a high speed; based on utilizing the bigger plastic compression deformation of foamed alloy material principle; the characteristics of high compression strength and good good impact toughness; organic cooperation of rigid material in addition; the function of fast wave-damping power consumption under effective performance of the rigidity support capacity under the realization action of static load and the percussion; reaching buffer protection function, thereby farthest avoid machinery production device damage and staff's casualty accident to take place to the miscellaneous equipment in the support system.

The specific embodiment
Embodiment, with reference to accompanying drawing 1 ~ 3, the bottom rigid sleeve 2 of mining fast wave-damping power consumption buffer is the cylinder of top barrel thickening, lower thread is connected and fixed outside bottom 6, externally in the bottom rigid sleeve 2 above the bottom 6 columned plasticity energy-absorbing material 5 is housed, energy-absorbing material 5 is reserved gap 2-1 with the inwall of bottom rigid sleeve 2.On energy-absorbing material 5, establish internal rigid bottom 4, the internal rigid bottom 4 fixedly top rigid sleeve 1 that is threaded, top rigid sleeve 1 overlaps with 2 top thickenings place of bottom rigid sleeve, is provided with trapezoidal groove 1-1 at top rigid sleeve 1 outer wall with the bottom rigid sleeve 2 inwall places of coincidence.Trapezoidal groove 1-1 place on rigid sleeve 1 outer wall of corresponding top, on bottom rigid sleeve 2, adorn four pin cards 3 with shape, pin card 3 is the annular less than 90 degree, the medial surface of annulus is provided with trapezoid boss 3-3, trapezoid boss 3-3 is installed in the trapezoidal groove 1-1 on top rigid sleeve 1 outer wall, the annulus both ends of the surface are equipped with adpting flange boss 3-1, adpting flange boss 3-1 is provided with screw hole 3-2, per two two adjacent adpting flange boss 3-2 all are connected with wing nut 9 with screw rod 7, and pocketed springs 8 outside screw rod 7.
The operating principle of mining fast wave-damping power consumption buffer is: place end in contact internal rigid bottom 4 on the plasticity energy-absorbing material 5 in the bottom rigid sleeve 2, the lower end is pressed on the outside bottom 6, does not bear the action of static load of support force and working resistance.Top rigid sleeve 1 embeds in the bottom rigid sleeve 2, trapezoid boss 3-3 on trapezoidal groove 1-1 on the top rigid sleeve 1 and the pin card 3 annulus medial surfaces coincide, rigid sleeve 1 usefulness pin card 3 in top is stuck in trapezoid boss 3-3 place, under the constraint of pin card 3, play the effect of bearing and transmitting static load, when shock loading surpasses nominal load-bearing capacity, top rigid sleeve 1 is broken through the constraint of pin card 3, sink to being embedded in the bottom rigid sleeve 2, by internal rigid bottom 4 impact compress energy-absorbing materials 5, bottom rigid sleeve 2 provides the effect of pin card 3 movable channels and constraint energy-absorbing material 5 distortion expansion, and 6 of outside bottoms are born in top static load and the impact compress process energy-absorbing material 5 bottoms to its pressure effect.Whole device plays the cushioning effect of fast wave-damping power consumption during bump to burst.
