Belt deflection correcting device

Abstract

The invention discloses a belt deflection correcting device. The device comprises supporting legs, a fixing bracket, and an aligning roller, a driving detection device and oil cylinders which are arranged on the fixing bracket, wherein the fixing bracket is a horizontal beam bridged on the supporting legs; the upper parts of the two ends of the fixing bracket are provided with an arc-shaped track respectively; the two arc-shaped tracks are concentric with each other; roller wheels at two ends of the aligning roller are embedded with the arc-shaped tracks; and the two ends of the aligning roller are hinged with oil cylinder piston rods on the fixing bracket. The device has a larger bottom space, a compact structure and greatly improved performance reliability and is convenient to mount. When a belt is deviated toward one side, the side edge of the belt touches the driving detection device and drives an oil pump to work, so that the oil cylinder piston rod on one side is extended, and the oil cylinder piston rod on the other side is retracted at the same time; the oil cylinders on the two sides perform reverse motion synchronously to drive the aligning roller to rotate; and transverse friction force is generated depending on a deflection angle formed between the rotating direction of the aligning roller and the advancing direction of the belt so as to finally realize a deflection correction function.

Description

A belt deviation correction device technical field The invention relates to a mine belt conveyor, in particular to a deviation correction device for a mine belt conveyor. Background technique With the continuous development of science and technology, the mechanization level of coal mines has been continuously improved. The history of transporting coal to the outside of the mine by manpower in the past has long since disappeared. Now almost all belt conveyors are used as the main tool for transporting coal. During the working process, the belt conveyor is affected by various factors such as uneven load, belt adhesion and belt thickness difference. Vertical idler axis. After the deviation, the side of the belt will rub against the adjacent objects, increasing the load on the motor, which not only affects the normal transportation, but also easily damages the equipment, which brings potential safety hazards. At present, almost all kinds of belt conveyors are equipped with d...

Problems solved by technology

Therefore, the height from the lower belt of the belt conveyor to the ground is relatively small, and the height from the lower edge of the rollers to the ground is even smaller, resulting in less than 100 mm of remaining space between the fixed beam and the belt conveyor installation foundation plane, which is easily destroyed by coal and coal falling off the belt. Buried in mud, the rollers are inflexible in rotation, and the swing beam of the corrector is blocked or even invalid. In addition, the rotating shaft on the upper swing beam and the shaft seat on the lower fixed beam will rust to death after being soaked in coal slime for a long time, resulting in the failure of the corrector.
