Problems solved by technology

However, this broken belt protection device still has some disadvantages: 1. When the upper brake block falls, there is a problem in the alignment, which requires high precision; 2. The structure is too complicated; 3. The tightening time is too long, which is not conducive to the broken belt protection

Abstract

The invention discloses a belt breakage protecting device of a belt conveyor. The belt breakage protecting device is in modular design and mainly comprises a frame, a support roller, grippers, a detector and a control system. The belt breakage protecting device is characterized in that each gripper is composed of a support web, a spiral guide mechanism, a drive motor, a coupler, a right-left threaded screw, a lower brake block, an upper brake block, a bearing seat and a fastening bolt. Under the control of a PLC (programmable logic controller), the drive motors runs to drive the right-left threaded screws connected with the same to rotate. With the right-left threaded screws, the upper and the lower brake blocks are driven by a spiral pair to move oppositely, leading to clamping motion of the broken belt. The detector is composed of an early warning bolt, a detector body, a rear slide block, a front slide block, a spring, a normally closed push button switch, a carrier roller, a bolt and a nut. Through the early warning bolt, reaction sensibility of the detector is adjusted according to tension of the belt.

Description

technical field [0001] The invention relates to mining machinery equipment technology, in particular to a broken belt protection device of a belt conveyor, the upper brake block of the broken belt protection device can be automatically rotated. Background technique [0002] Belt conveyors have many advantages such as low cost, high efficiency, and long distance, and are widely used in many industries. However, due to various reasons such as man-made and the belt itself, the belt conveyor often breaks the belt, causing damage to the belt, reducer and other related equipment. Even casualties. [0003] In China, the number of coal mines and the number of conveyors are large and the varieties are rich, far exceeding other countries in the world. However, compared with foreign countries, there is a big gap in the quality and reliability of domestic belt conveyors. The protection technology has also made some progress, but the technology is still not mature enough, so the convey...
