Main chute branch oblique chute ore drawing buffer protection device
The drop shaft that the utility model relates to a kind of metal mine industry unloads the oblique chute of ore deposit branch, is a kind of wear-resisting crash-proof main chute branch oblique chute ore drawing buffer protection device specifically.
Main chute is one of most important mining engineering of underground metal mine, whole ore deposits rock of underground mining is collection storage and transhipment thus all, it stablizes the whether unimpeded mine is produced influences greatly, produces in case destroy not only influence, and threatens whole slide to break the safety of system and main shaft.Main chute also is that the length of service is long, the abominable mine engineering of running environment simultaneously, deformation failure phenomenon ubiquity.It is numerous to cause drop shaft to destroy reason, and the impact failure when wherein unloading under the ore is one of major reason.The current domestic multistage adopts branch the oblique chute multistage to unload the perfectly straight well in ore deposit in the production mine simultaneously, when ore enters main chute by oblique chute to the main chute borehole wall impact, wear-out failure, form local failure face, if things go on like this multistage unloads the ore deposit and can form the unstable rock mass in many places, cavity at the borehole wall, causes drop shaft obstruction, partial collapse and then influences the use and the safety of whole drop shaft.Drop shaft destruction maintenance difficulty is big, the cycle long, the mine is produced influence greatly, can cause great economic loss.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of rolling, the main chute branch oblique chute ore drawing buffer protection device of ejection velocity when reducing ore and enter the main chute pit shaft is provided.
This main chute branch oblique chute ore drawing buffer protection device that the utility model provides comprises wear-resisting Crashworthy plate and will this wear-resisting Crashworthy plate suspends the suspention fixed combination parts of the oblique chute afterbody of branch in midair.
Described wear-resisting Crashworthy plate is combined by flexible adhesion by manganese steel plate, rubber tile, and described suspention fixed combination parts are combined by threaded anchor rod, suspension ring, hinge.Manganese steel plate thickness is 15mm, and rubber tile thickness is 30～60mm; Be connected by articulated form between described wear-resisting Crashworthy plate and the hinge.The body of rod of threaded anchor rod is a continuous thread, adopts between threaded anchor rod and the suspension ring to be welded to connect; Adopt articulated form to be connected between suspension ring and the hinge.
The beneficial effects of the utility model are: 1, utilize wear-resisting Crashworthy plate can effectively increase the chance that runs foul of each other, blocks before ore leaps to main chute; rolling, ejection velocity when the reduction ore leaps to main chute; when preventing that ore from entering pit 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 barrier effect of wear-resisting Crashworthy plate has reduced the impact wear of ore to oblique chute, plays the oblique chute effect of protection branch.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, utilize the fixing wear-resisting Crashworthy plate of anchor pole and hinge suspention, simple in structure, install change convenient, firm and reliable connection, wear-resisting, shock resistance good.

The specific embodiment
The utility model will be further described below in conjunction with the accompanying drawing specific embodiment:
Oblique chute ore drawing buffer protection device of the present utility model utilizes hinge 7, suspension ring 6, threaded anchor rod 5 that wear-resisting Crashworthy plate is fixed in branch oblique chute 3 afterbodys top.Wear-resisting Crashworthy plate is made by manganese steel plate 1, rubber tile 2, and manganese steel plate thickness is 15 millimeters, and rubber tile thickness is 30～60 millimeters, and rubber tile thickness is chosen by the ore fragmentation decision.Wear-resisting Crashworthy plate base shape is rectangle and circle, and concrete shape, size can be with oblique chute section configuration, size adjusting.Wear-resisting Crashworthy plate outpacking rubber plate has good buffering, shock-absorbing, isolating affection.When ore unloads to main chute 4 by ore dumping chamber under by oblique chute; because the barrier effect of the wear-resisting Crashworthy plate of suspention; increase the chance that ore runs foul of each other, blocks; rolling, ejection velocity when the reduction ore leaps to main chute 4; direct impact failure when effectively avoiding ore to enter main chute 4; reduced the impact wear of ore, reached the effect of the protection main chute borehole wall and the oblique chute of branch oblique chute.
