Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a mechanical belt pressing and deviation-correcting device for a belt conveyor. Background Art

[0002] The belt conveyor mechanical belt pressing and correcting device is a device used to correct the problem of conveyor belt deviation. The mechanical belt pressing and correcting device mainly corrects the deviation by applying lateral pressure to the conveyor belt. When the conveyor belt deviates, the belt pressing component of the correction device contacts the conveyor belt and uses the gravity of the pressure roller itself or the additional pressure applied by the mechanical structure to squeeze the conveyor belt toward the center position. When the conveyor belt deviates to one side and contacts the pressure roller, the pressure roller will rotate due to the friction of the conveyor belt, and at the same time generate a component force perpendicular to the deviation direction on the conveyor belt, so that the conveyor belt gradually returns to the correct operating track.

[0003] After searching, the Chinese patent announcement number is: CN216104228U, which discloses a conveyor belt automatic deviation correction device. The design concept of this utility model is that it is composed of a positioning frame, a tensioning bolt, a pressure plate, a guide rod, a compression spring and a driven roller bearing sleeve component to form a purely mechanical belt automatic deviation correction device. Due to the characteristic of equidistant constant pressure of the compression spring, when the conveyor belt produces position deviation during operation, the deviation force will be transmitted to the compression spring through the driven roller bearing. At this time, the compression spring will generate a reaction force to reversely push the driven roller, thereby restoring the conveyor belt to its normal position. This utility model solves a series of problems caused by conveyor belt deviation, ensures the normal operation of the belt conveyor, and improves the equipment. The operation efficiency and stability of the device are improved. In particular, the device does not destroy the overall position structure of the original equipment, nor does it affect the transmission effect of the equipment. At the same time, the automatic correction function does not require the help of an additional driving mechanism or additional energy, which can greatly save costs and energy consumption. In the existing belt conveyor mechanical belt pressing and correction device, the belt pressing and correction device uses a mechanical structure to generate pressure on the conveyor belt. When the conveyor belt is running, the belt pressing device can prevent the conveyor belt from deviating or drifting under heavy load, high speed or complex terrain conditions, thereby improving the conveying efficiency and reducing the unstable factors of the conveyor belt, reducing the wear and fatigue damage of the conveyor belt, and avoiding safety accidents caused by abnormal conveyor belt deviation.
