Full section broken belt protector for belt conveyor

Abstract

The invention discloses a full section broken belt protector for a belt conveyor, which belongs to the field of conveyors and mainly comprises a stand, an upper catching mechanism, a lower catching mechanism and a plurality of sensors, wherein the upper catching mechanism and the lower catching mechanism are mounted on the stand, and the sensors are mounted on a conveying belt; the sensors transmit collected signals to a PLC (Programmable Logic Controller) which sends a signal, firstly a transmission mechanism enables a revolution oil cylinder to work, a compaction oil cylinder works after time delay, and the upper broken belt catching mechanism compresses the conveying belt; and meanwhile, the revolution oil cylinder pushes the upper pressing block assembly, a pin shaft and a connecting bar of the upper pressing block assembly push the lower broken belt catching mechanism to move, and the lower broken belt catching mechanism quickly catches a lower conveying belt, thereby realizing the full section broken belt production of the conveyor. The full section broken belt protector for the belt conveyor can ensure the safety of machines, equipment and workers, and avoid the loss of state property.

Description

technical field [0001] The invention relates to the technical field of belt conveyors, in particular to a full-section broken belt protection device for belt conveyors. Background technique [0002] Belt conveyors are widely used in mining, metallurgy, chemical industry, light industry, coal, ports and many other fields. In the past, the tape was mainly inspected manually. Due to the long conveying distance of the belt conveyor and the harsh working environment, the maintenance was very inconvenient. Especially on a conveyor with a large inclination angle, a broken belt accident will basically bring about a tragedy of machine crash and human death. In order to overcome the loss caused by the broken belt accident. In recent years, some broken belt arresting devices have appeared on the market. In summary, most of the braking mechanisms are composed of cams, eccentric wheels, cranks, etc., and when braking, the sliding belt is clamped. Because it is a line contact, Therefor...

AI Technical Summary

Problems solved by technology

In recent years, some broken belt arresting devices have appeared on the market. In summary, most of the braking mechanisms are composed of cams, eccentric wheels, cranks, etc., and when braking, the sliding belt is clamped. Because it is a line contact, Therefore, the braking force is small and the reliability is not high. At the same time, the line contact on both sides of the tape is easy to cut and damage the tape. In severe cases, the tape will be torn; It is easy to cause false braking. For example, when the belt conveyor stops normally, the belt continues to go up by inertia and then stops. Although a backstop or brake is installed, it will slide a certain distance under the action of gravity, and it will Cause false braking, it is easy to damage the equipment, and cause accidents in severe cases

In addition, the body of the broken belt protection device is rectangular, and it is easy to fall over on an inclined plane.
