Conveyor Belt Protector

Abstract

The invention discloses a rubber belt protective device of a conveyor. The rubber belt protective device comprises a fixing frame (1). A conveyor rubber belt (2) is arranged on the fixing frame (1), a slide frame (3) with a pulley (5) is arranged on the fixing frame (1), a balance device is arranged on the slide frame (3), and the left end and the right end of the conveyor rubber belt (2) in a transmission direction are in slide fit with corresponding locations on the balance device in a butted manner; a protective device is further connected onto the balance device and is in slide fit with the slide frame (3), and alarm and shutdown signals can be transmitted by the protective device when the balance device fails. The rubber belt protective device has the advantages that the slide frame with the balance device and the protective device is arranged on the fixing frame, the alarm and shutdown signals can be transmitted by the protective device when the conveyor rubber belt is torn, damaged and rolled and transmission balance is lost, accordingly, the production safety can be guaranteed, and the rubber belt protective device is simple in structure and wide in application range and can be conveniently and quickly operated.

Description

technical field [0001] The invention relates to the field of conveyor manufacturing, in particular to a conveyor belt protection device. Background technique [0002] At present, belt conveyors are mainly used for mine material transportation. The feeding point of the conveyor is the section where the conveyor belt is often torn, especially at the feeding point equipped with a loading funnel, it is very easy to cause the accident of the conveyor belt torn; this kind of accident is mainly due to the loading material mixed with iron or large During the throwing movement of the block material, its sharp edge or sharp angle directly pierces the conveyor belt, causing a tearing accident of the tape; and the shape of the conveyed material is large, and part of it is stuck in the mouth of the funnel. At this time, the tape continues to run forward. Due to long-term wear, the tape is worn through, and the larger material is like a pair of scissors tearing the conveyor belt into two...

The feeding point of the conveyor is the section where the conveyor belt is often torn, especially at the feeding point equipped with a loading funnel, it is very easy to cause the accident of the conveyor belt torn; this kind of accident is mainly due to the loading material mixed with iron or large During the throwing movement of the block material, its sharp edge or sharp angle directly pierces the conveyor belt, causing a tearing accident of the tape; and the shape of the conveyed material is large, and part of it is stuck in the mouth of the funnel. At this time, the tape continues to run forward. Due to long-term wear, the tape is worn through, and the larger material is like a pair of scissors tearing the conveyor belt into two parts

Since the tape forms a half-circular groove on the U-shaped wheel, after the tape is torn, the tapes on both sides of the crack tend to converge inward along the sides of the groove; therefore, after the tape is torn, it often does not open a big mouth, but tears The tape on both sides of the seam overlaps to seal the gap, and the infrared sensor is not ideal for detecting such accidents

When there is less material on the tape, it is not easy to leak, resulting in a delay in the response to tearing accidents based on material leakage and light leakage detection. Only when the tape is torn to a considerable length, there is a large material leakage and light leakage. The protective device only works
