Description

The belt conveyer broken belt is arrested device

Technical field:

The utility model relates to a kind of belt conveyer broken belt and arrests device, when being used for belt conveyer and upwards transporting unexpected broken belt, load-transfer device is pinned, and avoids causing equipment and personal injury accident.

Background technology:

Belt conveyer is widely used in places such as mine, colliery, harbour, and when belt conveyer upwards transported unexpected broken belt, belt can produce slip, caused equipment and personal injury accident easily.Existing belt conveyer broken belt is arrested device and mostly is the brake shoe oscillating type, the brake shoe of arresting device is fixed on the frame, be suspended from the top of belt, after the conveyer belt load, because the material that transports on the belt is inhomogeneous, fixing brake shoe is easy to the material that transports is produced barrier effect and causes solid accumulation, it is scattered in outside the belt, long-play causes deposit to increase, if untimely processing can cause transportation malfunctioning, and need often clear up deposit, both lavished labor on, influence production efficiency again, even can cause the misoperation of catching device and damage equipment delays production.

Summary of the invention:

The purpose of this utility model provides a kind of belt conveyer broken belt and arrests device, and after the conveyer belt load, brake shoe can not stop the material that is transported, and avoids the misoperation of catching device.

The purpose of this utility model realizes as follows: a pair of position adjustable broken belt arresting agency is set on frame, the broken belt arresting agency is by Non-return idler, eccentric shaft, finger, connecting rod, latch, the braking brake shoe, pivoted arm, torsion spring, the wedge frame is formed, Non-return idler supports by eccentric shaft and is in below the conveyer belt, eccentric shaft is fixed on the frame, fixed wedge frame on the frame, on the porose axle that is enclosed within on the wedge frame of pivoted arm one end, between pivoted arm and the wedge frame torsion spring is set, the other end of pivoted arm is provided with the braking brake shoe, the boxed rod that wedge frame upper hinge can swing up and down, but fixing up-down adjustment is gone up at pivoted arm middle part and its lower end can be inserted in the latch in the boxed rod end hole, the hinged lower link of swinging on the frame, between one section of lower link and the boxed rod hinged in connecting rod, the other end of lower link has open slot, be supported on the finger by this open slot, finger is fixed on the check that is in the Non-return idler inner chamber and puts.Before the work, overcome the torsion spring application force and move pivoted arm and make the braking brake shoe be in the conveyer belt outside, the latch on the pivoted arm is inserted in the hole of boxed rod the pivoted arm location, and Non-return idler rotates with belt under conveyer normal operation situation; Belt reversing during broken belt, Non-return idler drives the eccentric shaft rotation of check cover around carrying roller, the finger of check cover end is stirred lower link, thereby connecting rod spurs boxed rod downwards in making, make latch deviate from, pivoted arm is turning under the effect of torsion spring above the belt, chokes broken belt to lower slider with the Non-return idler that rotates up around eccentric shaft, realizes the purpose of arresting.

Check has put eccentric orfice, be enclosed within on the eccentric shaft by this eccentric orfice, adorn finger on the check cover end face eccentric position, check cover cylindrical is by the bearings Non-return idler, outside race is provided with unidirectional ratchet by axle and torsion spring by fixing with Non-return idler bonded assembly bearing cap shim on the bearing cap shim, on the check cover circumference skewed slot that can hold the ratchet front end is arranged, be with on the eccentric shaft and bearing cap shim between the leak free seal cover cap, their constitute Non-return idler assembly.During the rotation of Non-return idler positive dirction, ratchet slides around check cover surface, and Non-return idler rotates around the check cover; Behind broken belt, Non-return idler is backward rotation under the effect of belt friction force, and ratchet fastens the check cover, make the check cover with the Non-return idler backward rotation, make finger center on eccentric shaft and rotate, and then stir connecting rod, make the action of braking brake shoe, move on the relative eccentric shaft of Non-return idler simultaneously.

The utility model belt conveyer broken belt is arrested device; pivoted arm and braking brake shoe are in the belt outside at ordinary times; thereby after the conveyer belt load; the braking brake shoe can not stop the material that is transported, and avoids solid accumulation to be scattered in outside the belt, has exempted frequent cleaning work; reduced the manpower work; improve production efficiency, avoided the misoperation of catching device, can be used for the broken belt protector of the belt conveyer at mine, colliery, harbour.
