Self-inspection control type belt deviation correction device

Abstract

The invention discloses a self-checking control type belt deviation rectifying device. The self-checking control type belt deviation rectifying device comprises a belt deviation detecting device (2), a hydraulic station (7) and an executing mechanism, wherein the executing mechanism comprises a deviation rectifying cylinder (11) and a deviation rectifying drum (8), the deviation rectifying drum (8) is mounted on two deviation rectifying drum bearing seats (9) on two sides, one deviation rectifying drum bearing seat on one side is mounted on a sliding bottom plate (17) and is connected with a deviation rectifying cylinder piston rod, and the other end of the deviation rectifying cylinder is mounted on a cylinder base (12). The deviation rectifying drum bearing seat on the other side is mounted on a fixed base (15) via a cuphead pin (16) and can swing along the same. A left cavity and a right cavity on two sides of the piston in the body of the deviation rectifying cylinder are connected with the hydraulic station (7) through hydraulic oil pipes (10). Output of a belt deviation detecting device is connected with a PLC (programmable logic controller), and the PLC controls output of the hydraulic station to control stretching of the deviation rectifying cylinder, and thus, the deviation rectifying cylinder can be controlled to rectify deviation of a belt (5).

Description

technical field [0001] The invention relates to a belt deviation correcting device of a belt conveying system. Background technique [0002] The belt conveyor system is the key equipment for the barge of mineral materials in major ports. Belt conveyors consist of belt driven pulleys, belt driven pulleys, buffer roller sets, return belt underpressure rollers and a conveyor belt (belt) around which the belt runs The lower pressure rollers operate to convey the material placed on the belt from one place to another. Therefore, it is very important whether the conveyor belt can always be in a stable and reliable running state. However, during the operation of the belt, due to equipment manufacturing, installation, and uneven material distribution in the direction of the belt width, it is inevitable that the belt will deviate, and the deviation is serious. It can directly lead to damage to the belt and paralyze the work of the equipment. Belt deviation is the most common abnorm...

Problems solved by technology

As a result, a large amount of material leaked out, not only the surrounding environment was polluted, but also the people in the area were physically and mentally injured. Therefore, the stability and reliability of the reversible two-way conveyor belt directly affects the safety and smooth operation of the entire production system.

At the same time, there is a big gap between the means of manual intervention and adjustment and the development requirements of modern ports
