Belt anomaly induction device of transportation belt conveyor and implementation method of belt anomaly induction device

Abstract

The invention discloses a belt anomaly induction device of a transportation belt conveyor and an implementation method of the belt anomaly induction device. The transportation belt conveyor compriseshanging steel wire ropes, a plurality of upper supporting rollers are arranged on the hanging steel wire ropes at intervals, and a belt is laid on the upper surfaces of the upper supporting rollers; and the induction device comprises a support, an upper plate, a lower plate, an induction block and a receiver, wherein the support is arranged below the hanging steel wire ropes, a cross beam is arranged on the support, the lower plate is horizontally fixed on the cross beam, the upper plate is arranged between the lower plate and the belt, moreover, the middle of the upper plate is rotationally connected with the middle of the lower plate through a rotating shaft, the induction block and the receiver are arranged at one end of the upper plate and one end of the lower plate respectively, furthermore, the receiver is further connected with a shutdown circuit of the transportation belt conveyor, and a reset spring is further arranged between the other end of the upper plate and the other endof the lower plate. According to the belt anomaly induction device of the transportation belt conveyor and the implementation method of the belt anomaly induction device, local accident detection andautomatic shutdown control of the belt are realized, the operation protection effect of the belt conveyor is improved, and the advantages of being low in cost, safe, remarkable in economic effect andthe like are achieved.

Description

Technical field [0001] The invention relates to the technical field of belts, in particular to a belt abnormality sensing device of a conveyor belt conveyor. Background technique [0002] With the continuous upgrading of modern mine machinery and equipment, belt conveyors have become more and more widely used. At present, the safe operation of belt conveyors depends on control systems, including protection systems, video systems, and equipment status monitoring systems. However, detection of partial belt accidents cannot be achieved. Especially at the reprinting point, relying on video alone cannot achieve timely shutdown after failure. [0003] Generally, mine belt conveyors take a long time to transport, complex types of cargo, and large impacts at the transfer point. The belt is often scratched by metal objects or large gangue falling from the discharge port, or partially overloaded, partially deviated, and buffered. Phenomena such as idler damage will increase the unfavorable ...

Problems solved by technology

[0002] With the continuous upgrading of modern mine machinery and equipment, the application of belt conveyors is becoming more and more extensive. At present, the safe operation of belt conveyors depends on the control system, including protection systems, video systems, equipment status monitoring systems, etc., but local belt accidents cannot be detected. Especially at the transfer point, relying solely on video cannot achieve timely shutdown after a fault

[0003] Generally, mine belt conveyors take a long time to transport, and the types of goods they carry are complex, and the reloading point is greatly impacted. The belt is often scratched by metal objects or large pieces of gangue falling from the discharge port, or partially overloaded, partially deflected, and buffered. Idle roller damage and other phenomena will increase the unfavorable factors for the safe operation of the belt conveyor. For example, increasing the thickness of the belt surface or changing the strength of the belt core will inevitably increase the input cost
