Belt tear opening shaping structure and belt conveyor

Abstract

The invention relates to a belt tear opening shaping structure and a belt conveyor. The belt tear opening shaping structure includes a shaping idler set, a grooved idler set and an idler stand. The shaping roller group includes the middle shaping roller, the first side shaping roller and the second side shaping roller arranged at both ends of the middle shaping roller. The first side shaping idler and the second side shaping idler are both inclined and inclined towards the middle shaping idler. The middle shaping roller and the first side shaping roller are arranged at intervals, or the middle shaping roller and the second side shaping roller are arranged at intervals. The shaping roller group is arranged parallel to the grooved roller group along its length direction, and the grooved roller group includes the middle roller. Both the trough roller group and the shaping roller group are arranged on the roller frame, and the distance from the middle shaping roller to the bottom of the roller frame is greater than the distance from the middle roller to the bottom of the roller frame. The mechanism ensures that the tear detection device detects the tear, and the staff can repair the belt conveyor in time to reduce economic losses.

Description

technical field [0001] The invention relates to the technical field of anti-tearing belt conveyors, in particular to a belt tear opening shaping structure and a belt conveyor. Background technique [0002] At present, belt conveyors are widely used in the field of bulk cargo transportation in ports and mining areas. The type of belt used in the belt conveyor is mainly a steel cord conveyor belt, which has extremely high strength and good grooving performance, and is suitable for high-speed, large-load, and long-distance continuous transportation. However, during the process of transporting materials, impurities from the materials or sharp objects falling from the transport equipment can easily scratch the bearing surface of the belt. After the belt is scratched, it can be detected by a tear detection device such as a mechanical drawstring detection device, an X-ray camera device, and a weighing sensor detection device. However, due to the imperfection of the technology, in...

Problems solved by technology

However, due to the imperfection of the technology, in practical applications, there will be situations where the belt has been torn but the tear detection device cannot detect it

For example, after the belt is scratched, the material on the belt will not leak from the tear opening to the bottom of the tear opening or get stuck in the middle of the tear opening, causing the tear detection device under the belt, such as a drawstring detection device, weighing The sensory detection device cannot detect the tearing fault, so that sometimes the tearing fault cannot be detected in time, so that the tearing range is not controlled, and finally the staff spends a longer time repairing the belt conveyor, which also causes greater damage. economic loss
