Mining belt conveyor control and protection system

Abstract

The invention belongs to the technical field of conveyor control and protection, and particularly relates to a mining belt conveyor control and protection system. The mining belt conveyor control andprotection system comprises a supporting frame and a carrier roller frame, wherein a carrier roller is connected to the carrier roller frame, a conveying belt is arranged at the top end of the carrierroller, and hemispherical protrusions are evenly distributed on the bottom face of the conveying belt; a roller is arranged at the end of the supporting frame, wherein grooves corresponding to the protrusions of the conveying belt are annularly and evenly formed in the side face of the roller; and a KZX-48K mining flameproof and intrinsic safety PLC control box is arranged on the supporting frame. According to the mining belt conveyor control and protection system, through the arrangement of an anti-deviation structure and the control box, deviation and damage of the conveying belt caused bysliding of the conveying belt on the roller can be reduced, and deviation of the conveying belt can be effectively detected and controlled; and meanwhile, the control box adopting a intrinsic safety modular design, so that production cost is saved, the severe environment in mining operation can be effectively coped, and the working quality of the belt conveyor is improved, and the service life ofthe belt conveyor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of conveyor control and protection, in particular to a mine belt conveyor control and protection system. Background technique [0002] Full-efficiency coal mine main transportation equipment is an important part of automated and intelligent mines. Among them, mine belt conveyor is the key equipment of coal mine main transportation system. During the working process of belt conveyor, the transmission of driving force is mostly By arranging a high-power drive motor at the head position of the belt conveyor, the driving force is transmitted to the head roller through the reduction box, and the transmission between the head roller and the belt is realized through static friction without relative motion. [0003] However, the belt conveyor is often affected by impact loads during operation. At this time, the drive motor needs to increase the output torque according to the load, which also leads to an increase in ...

AI Technical Summary

Problems solved by technology

[0003] However, the belt conveyor is often affected by impact loads during operation. At this time, the drive motor needs to increase the output torque according to the load, which also leads to an increase in the tension of the conveyor belt at the head of the belt conveyor. Reasonable control will easily cause the deviation of the conveyor belt at the head part, and in severe cases, it will cause the conveyor belt to tear or even break the belt, which not only affects the smooth progress of production, but also increases the production cost due to equipment maintenance and replacement. ; and the environment of mining operations is often dangerous and harsh. At this time, if the conveyor cannot be effectively comprehensively protected, it will also cause harm to the life and health of the staff
