How Rubber Belt Deviation Correction

Mar 30, 2019

When the deviation occurs, the side of the belt will rub against the adjacent objects, increasing the motor load, which not only affects the normal transportation, but also damages the equipment and brings safety hazards. At present, almost all kinds of conveying machines are equipped with deviation correction. The device is used to ensure normal production and safe production. Nowadays, the common deviation correction devices mainly include the central deviation correction and the end deviation correction device. The end correction device adjusts the roller of the conveyor, and the middle deviation is the adjustment belt conveyor. The aligning roller, through the direction of the line movement of the outer circle of the belt roller on the aligning roller, forms an angle with the moving direction of the annular rubber band, and generates a lateral sliding friction force to drive the belt to be centered. Partial correction devices, such as: automatic hydraulic regulators, passive hydraulic correctors, hydraulic centering devices and integrated hydraulic correctors, etc., most belt conveyors use this similar structure: drive the centering roller by the roller, The upper swinging beam and the lower fixed beam are arranged, the roller is mounted on the upper swinging beam, and the upper swinging and the lower fixed beam are connected by the rotating shaft and the shaft seat, and fixed The beam must be below the oscillating beam, so the height of the nylon rubber conveyor belt on the lower layer of the belt conveyor is relatively small, and the height from the lower edge of the roller to the ground is smaller, resulting in insufficient space for the fixed beam to the plane of the conveyor installation foundation, which is easy to be The coal and slime that have fallen off from the heat-resistant conveyor belt are buried, causing the roller to rotate inflexibly, and the swinging beam of the corrector is blocked or even failed. In addition, the shaft on the upper swinging beam and the shaft seat on the lower fixed beam are bubbled in the coal for a long time. The mud will rust, causing the corrector to fail, and it is difficult to clean up;


In order to solve the above problems, the rubber belt deviation correction device can be realized by a compact structure, convenient installation and more reliable performance, and the structure thereof comprises: a leg, a fixing bracket and a rubber belt centering bracket mounted on the fixing frame. The roller set, the inspection drive device and the oil cylinder are characterized in that: the fixed bracket is a horizontal beam spanning on the leg, and an arc-shaped rail is respectively arranged above the two ends of the bracket, and the two rails are arranged in the same center. The roller at both ends of the aligning roller is engaged with the curved track, and the two ends of the aligning roller are hinged with the piston rod of the cylinder mounted on the fixing bracket, and when the belt on the belt conveyor is deflected to one side, The side of the side will be in contact with the same side of the inspection device, which will drive the corresponding oil pump to work, so that the piston rod of the same side cylinder is extended, and the piston rod of the other side cylinder is retracted, so as to realize the synchronous reverse action of the two cylinders, The rotation of the aligning roller and the eccentricity of the direction of the direction of the heavy-duty conveyor belt by the direction of rotation of the aligning roller to generate the lateral friction force, finally achieving the function of correcting the deviation;
