Pipe belt machine and broken belt capturing device thereof

Abstract

The invention discloses a pipe belt machine and a broken belt capturing device thereof, two sides of a support are respectively provided with an inclined rack, two side shaft ends of a carrier roller shaft are respectively and fixedly provided with a gear meshed and matched with the rack, and a carrier roller body is sleeved on the carrier roller shaft; the carrier roller body is provided with a plurality of overturning capturing pieces which are circumferentially arranged on a peripheral body at intervals, the carrier roller shaft and the carrier roller body can rotate synchronously in one direction, and the carrier roller shaft and the carrier roller body rotate asynchronously when the conveying belt moves forwards to drive the carrier roller body to rotate in the first direction; when the conveying belt moves reversely to drive the carrier roller body to rotate in the second direction, the carrier roller shaft and the carrier roller body rotate synchronously, the carrier roller shaft and the carrier roller body can be sequentially meshed along the racks through the gears and form the trend of tooth displacement towards the second ends of the gears, and the overturning capturing piece is located at the capturing working position. By means of the scheme, reliable capturing operation can be achieved through quick triggering when belt breakage accidents happen, and technical guarantee is provided for safe and reliable operation of a conveying system.

Description

technical field [0001] The invention relates to the technical field of material conveying, in particular to a pipe conveyor and a broken belt arresting device. Background technique [0002] At present, the tube belt conveyor has been widely used in electric power, metallurgy, port and other industries due to its good comprehensive conveying performance, and has a development trend of large-capacity and long-distance. As we all know, for the conveyor belt conveyor, the tension on the conveyor belt is very large during the material lifting process, and the motor needs to output a large torque to drive the conveyor to run normally. During the long-term continuous operation of the conveyor belt, fatigue damage or damage by foreign objects may occur, which may cause the conveyor belt to suddenly break during operation, which is called broken belt. [0003] When a belt break occurs, the conveyor belt will slide backwards at high speed with the material. Due to the large transpor...

AI Technical Summary

Problems solved by technology

Due to the large transport volume and long distance, the backward slide of the material will continue to accelerate, and the kinetic energy is very huge. The material entrained by the conveyor belt will destroy the conveyor frame and damage the roadway, causing long-term production stoppage and major economic losses, and even affecting on-site work. personal safety of personnel

[0004] In order to solve this problem, the existing technology proposes to install a broken belt arresting device on the belt machine. This solution includes a catch mechanism and a trigger mechanism. The trigger mechanism includes a driving idler and a ratchet guide assembly. As a switch that triggers the torsion spring, the triggering force is small, and the upper roller often does not touch the tape, so there is a defect of low reliability
