Description

Technical Field

[0001] The utility model relates to the technical field of backstops, and specifically to a belt backstop. Background Art

[0002] A belt backstop is a device used to prevent the belt from reversing after the machine stops. When the machine needs to stop, the belt backstop can quickly stop and lock the belt to prevent it from reversing, thus protecting other machines and tool equipment. The material quality and manufacturing process of the belt backstop directly affect its service life and performance. If the manufacturing quality is poor, problems such as fracture, wear, and cam deformation may occur after long-term use, resulting in the belt backstop losing its function. During the operation of the belt backstop, improper use is also likely to cause damage. During use, the backstop is prone to overheating. The main reason is that when the friction plates inside the backstop rotate at high speed, sufficient lubricating oil is required to reduce the heat generated by friction. If the lubrication system fails or the quality of the lubricating oil is poor, the friction between the friction plates will increase, resulting in a large amount of heat generation. When the belt conveyor operates under overload, the pressure on the reducer and the backstop will increase exponentially, which will cause excessive wear of the friction plates inside the backstop, resulting in excessive heat generation. The backstop is usually installed on the output shaft of the reducer, and this position often has a small space and poor heat dissipation conditions. If the surrounding environmental temperature is too high or the heat dissipation system design is unreasonable, it will cause poor heat dissipation of the backstop, resulting in a continuous increase in temperature. When the temperature is too high, the friction plates inside the backstop are prone to deformation, wear, and ablation at high temperatures, which will seriously affect its service life. At the same time, high temperature will accelerate the oxidation and deterioration of the lubricating oil, further aggravating the wear of the friction plates. Excessive temperature will cause changes in the friction coefficient inside the backstop, affecting its transmission efficiency, which will cause problems such as speed fluctuations and uneven forces during the operation of the belt conveyor, seriously affecting production efficiency and product quality. At the same time, high temperature will cause thermal expansion of the parts inside the backstop, resulting in a smaller clearance fit and even jamming, which will increase the risk of backstop failure and may even cause it to completely fail in severe cases. When the temperature of the backstop is too high, there may be safety accidents such as fires. Summary of the Utility Model
