Hydraulic constant-torque heavy-section sweeper for belt conveyor

Abstract

A hydraulic constant-torque heavy-section sweeper for a belt conveyor mainly comprises a sweeping block subassembly, a rotating mechanism, a hydraulic system and the like, wherein the sweeping block subassembly comprises a sweeping block and a slotted-angle shelving; the rotating mechanism comprises a rotating arm, a supporting plate and a reinforcing plate; a guiding device comprises a locking nut, a guiding head, a connecting rod, a disc spring and the like; the hydraulic system comprises a hydraulic cylinder, a hydraulic rubber tube and an energy accumulator; the sweeping block subassembly is connected with the rotating mechanism; the rotating mechanism is connected with the connecting rod through a hinge pin; and the connecting rod is connected with a piston rod in the hydraulic cylinder. When hydraulic force pushes the rotating mechanism to rotate through the connecting rod, the sweeping block subassembly is driven to rotate and compresses a rubber belt, the torque of a rotating arm can be automatically adjusted along with abrasion of the sweeping block, and keeps constant, and a contacting section of the sweeping block and the rubber belt is not changed. In addition, the sweeper has the advantages of simple structure, convenience in installation, high sweeping effect, long service life and the like.

Description

technical field [0001] The utility model relates to a device for cleaning the conveyor belt of a coal mine belt conveyor. Background technique [0002] The belt conveyor is the key transportation equipment in coal mine production, and the heavy section cleaner is an indispensable supporting device for the belt conveyor. It is installed directly in front of the driving drum of the belt conveyor head or under the coal unloading drum. To clean the residue of coal slime adhering to the working surface of the belt conveyor after unloading coal, and make it fall into the head hopper. Since the belt conveyor relies on the friction between the belt and the driving roller to transmit power, the cleaning effect of the belt surface directly affects the service life and stable operation of the belt conveyor. With the rapid improvement of comprehensive mechanized coal mining technology, the operating speed and transportation capacity of the belt conveyor have also been further increased...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the shortcomings of current existing cleaners such as poor adjustability, high replacement frequency, heavy maintenance workload, poor cleaning effect, and short service life, the present invention provides a hydraulic constant-torque heavy-section cleaner for belt conveyors, which can be used along with The wear of the cleaning block during work can automatically compensate for the gap between the cleaning block and the tape after wear, and maintain a constant contact force and cleaning force between the cleaning block and the tape, which can reduce the wear with the tape and achieve ideal The cleaning effect is very good, prolonging the service life of the cleaner, and a travel switch is installed on the cleaner; when the cleaning block wears to the limit position, the rotating arm will touch the travel switch, so that the belt conveyor will automatically stop and prevent the cleaner from metal damage to the tape or cause equipment accidents
