Problems solved by technology

Because the electro-hydraulic deviation correction device needs power supply, and because the belt deviation correction often requires its frequent actions, and the working environment is poor, there is a high failure rate and the deviation correction force is often insufficient.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] The belt (12) is placed on the idler roller (11) of the passive hydraulic control linkage self-correcting machine. The inspection drive wheel (1) oil pump (2) is between the idler on the driving idler bracket (8) and the idler on the driven idler bracket (10), on both sides of the edge of the belt (1). The thermostat (13) is higher than the level of the oil pump (2) and is installed on the frame (14). The central control station (6) is fixed on the frame (14). The cylinder body of the oil cylinder (4) is hinged with the frame (14), and the end of the piston rod is hinged with the end of the active arm rod (5).

[0021] Each oil port of the oil pump (2), oil cylinder (4), and thermostat (12) is connected to the central control station (3) through oil pipes.

[0022] When the belt (12) runs off-center, the edge of the belt (12) touches the detection drive wheel...

Abstract

A passive hydraulic control linkage rectification machine which can rectify and prevent the run deviation of a conveyor belt consists of a hydraulic control detecting and driving system and a linkage rectification mechanism. The hydraulic control detecting and driving system consists of a detecting and driving wheel, an oil pump, a cylinder, a midpoint controlling station, a temperature controller and an oil pipe. The linkage rectification mechanism consists of discrete rollers, roller racks, a universal joint, an arm rod, a connecting rod, a pin and a frame. The hydraulic control detecting and driving system is used to detect the run deviation of the belt and simultaneously supplies power for driving the roller racks to deflect. When the belt runs deviated, the belt drives the detecting and driving wheel to rotate. The detecting and driving wheel drives the oil pump to strike the oil pressure to the midpoint controlling station. A logistic valve group of the midpoint controlling station controls the piston rod of the cylinder (4) to push or pull. The piston rod drives the linkage rectification mechanism to lead the roller (11) on the mechanism to deflect synchronously in the same direction. An angle is formed between the linear moving direction of the roller after the deflection and the moving direction of the belt, and the transverse friction of the belt generating during the above process drives the belt to run in the middle. The passive hydraulic control linkage rectification machine requires no power and hydraulic function and has the advantages of synchronous linkage, self-defecting, self-driving and self-system.

Description

technical field [0001] The invention relates to a deviation correcting device for correcting and preventing the deviation of the belt during operation on a belt conveyor. Background technique [0002] At present, the deviation correction devices used in various belt conveyors are mainly various self-aligning rollers, forward-inclining rollers and electro-hydraulic deviation correction devices. [0003] No matter what kind of self-aligning roller, the principle of correcting the deviation of the belt is assumed: when the center of the belt deviates from the longitudinal centerline of the conveyor frame, the self-aligning roller mechanism should detect the deviation of the belt and make the adjustment The center roller frame deflects, and after the deflection, the movement direction of the self-aligning roller line forms an angle with the movement direction of the belt. At this time, a lateral friction force of the belt is formed between the self-aligning roller and the belt. ...
