The utility model content
The purpose of this utility model is to provide a kind of shock resistance and anti-wear performance is good, the oblique chute protective equipment of long service life.
The oblique chute protective equipment of this main chute that the utility model provides and branch thereof, this facility comprises some wear-resisting Crashworthy plates that are arranged in branch oblique chute both sides, the upper and lower dual-side of wear-resisting Crashworthy plate has fixed part, the flexible stretch-draw stressing device in the one side in the side of the left and right sides; Elasticity stretch-draw stressing device comprises the stretch-draw member and is connected in elastic force balance member between the stretch-draw member, and a side and the wear-resisting Crashworthy plate of stretch-draw member are fixed, and opposite side is connected with anchor pole.
Described stretch-draw member is v-component, comprises two blocks of connection steel plates that connect with V-arrangement, connects steel plate and is bonded with rubber tile outward.
The equidistant interlaced arrangement of described wear-resisting Crashworthy plate, its width is half of the oblique chute width of branch, comprises steel plate, a side of steel plate and the welding of a side of described v-component, the two sides of steel plate is bonded with rubber tile.
Described fixed part comprises threaded anchor rod, suspension ring and hinge, and hinge is connected between described wear-resisting Crashworthy plate and the suspension ring, the upper end connecting thread anchor pole of suspension ring.
Described elastic component adopts the compression spring.
Described anchor pole adopts the fried dough twist anchor pole.
The utility model is controlled following the unload speed of ore in the oblique chute of branch by having the wear-resisting Crashworthy plate of elasticity stretch-draw stressing device, rolling, ejection velocity when the reduction ore enters the main chute pit shaft.Wear-resisting Crashworthy plate outpacking rubber plate has good buffering, shock-absorbing, isolating affection.
The utility model is controlled following the unload speed of ore in the oblique chute of branch by the wear-resisting Crashworthy plate that has elasticity stretch-draw stressing device; has advantage: 1, can effectively reduce ore and under the oblique chute of branch, unload speed; increase the chance that runs foul of each other, blocks before ore enters main chute; rolling, ejection velocity when significantly the reduction ore leaps to main chute; when preventing that ore from entering drop shaft to the borehole wall impact, wear-out failure; effectively protected the drop shaft borehole wall; reduce drop shaft and damaged factor, increased drop shaft safety in utilization, validity.2, the retardation with the wear-resisting Crashworthy plate of elasticity stretch-draw stressing device has reduced the ore rolling speed, has reduced the impact wear of ore to the oblique chute base plate of branch, sidewall, has increased the oblique chute safety in utilization of branch and application life.3, wear-resisting Crashworthy plate outpacking rubber plate shock-absorbing function of shock insulation for the noise that reduces operating point, alleviate vibrations, improve working environment good effect is arranged.4, can effectively reduce the dust that produces when unloading under the operating point ore by the rolling speed that reduces ore, improve the operating point air ambient.5, utilize anchor pole fixedly elasticity stretch-draw primary structure member and wear-resisting Crashworthy plate, simple in structure, it is convenient install to change, and firm and reliable connection is wear-resisting, shock resistance good.6, effectively protected the oblique chute structure of main chute and branch thereof, the wear-resisting Crashworthy plate with elasticity stretch-draw stressing device is substituted by the set steel liner plate enclosed structure of the protection oblique chute of branch, saves construction investment, can produce good economic benefits.
