AI Technical Summary

Technical Problem

The tension of existing coal mine inclined shaft belt conveyors is greatest in the top section of the inclined shaft, which makes the conveyor belt prone to breakage. The existing equipment lacks a timely and effective protection mechanism, which poses a risk of belt breakage accidents and threatens safety and production efficiency.

Method used

Design a conveyor belt anti-breakage device for inclined roadway transport in coal mines. It adopts follow-up components and brakes, and realizes full-process traction and braking of the conveyor belt through pre-embedded connectors and steel wire rope connecting chain connectors. It includes a mechanical locking mechanism of the brake to avoid delayed response of electronic components.

Benefits of technology

It effectively reduces fatigue damage to the conveyor belt in the high-tension zone, ensures the flexibility of normal operation, provides instant locking protection in case of belt breakage, significantly improves the reliability of emergency protection, and avoids equipment damage and personnel danger.

Abstract

This utility model discloses a belt breakage prevention device for inclined conveyor belts in coal mines, including a conveyor, a connecting assembly, and a follower assembly. The follower assembly is symmetrically arranged on both sides of the conveyor. The connecting assembly includes multiple pre-embedded connectors, which are uniformly embedded and fixed inside the conveyor belt. Each pre-embedded connector has a steel wire rope fixed at both ends, and a chain connector is fixedly connected to the other end of each steel wire rope. The follower assembly includes a frame, with a drive shaft rotatably connected to both ends of the frame. A brake is installed on the shaft of the drive shaft located outside the frame, and a drive motor is installed at the shaft end. A sprocket and chain drive assembly is installed inside the frame. The follower assembly provides auxiliary drive through rigid chain tension during the belt's ascent, effectively sharing the belt load in the high-tension zone at the top of the inclined roadway, reducing stress concentration at joints and weak points, and lowering the probability of breakage from the source. This solves the problem of existing devices only providing passive responses.
