　　Tai'an Yucheng has been researching and producing the 2JP-22 ore rake winch for many years. After multiple upgrades and renovations, the 2JP-22 ore rake winch currently available for sale is simple, reliable, and has fewer accidents during operation. It can also complete the three stages of loading, transportation, and unloading, with flexible and diverse layout plans for easy installation and disassembly. It is suitable for a wide range of conditions, especially for ores with high fineness, specific gravity, and block size, which other transportation machinery cannot match. But its work efficiency is not high. When the rake distance is above 4050 meters, it significantly reduces the reasonable haul distance to around 10-30 meters, and rarely reaches 100 meters. It is not suitable for long-distance rake transportation in high-intensity mining methods.

　　The main body of the 2JP-22 ore rake winch is an electric winch, which pulls a rake bucket through a steel wire rope wrapped around a working drum and an unloaded drum. The rake bucket excavates minerals on the working surface and completes the transportation to another place. Due to the high resistance caused by the direct raking of minerals at the bottom, the power consumption is high. Additionally, due to the structural limitations of the raking winch itself, it is only suitable for horizontal and inclined surfaces less than 50 degrees, and cannot be used for lifting, lowering heavy objects, or transporting people.

　　2JP-22scraper winch Malfunctions and maintenance

　　The mining winch is a relatively simple and reliable equipment, with few operational failures during normal operation, but sometimes some problems may occur. For example, if the brake strip breaks, the motor seat cracks, or the motor rotates but the drum cannot wrap around the steel wire rope.

　　The breakage of two brake belts and the appearance of cracks in the motor seat are caused by overload. During the operation of the electric rake winch, the rake bucket sometimes encounters excessive resistance and is difficult to move forward. In this case, the rake bucket should be moved back a distance before continuing to rake; Never forcefully pull to avoid damaging the electric rake equipment and causing personal accidents.

　　The brake belt of the winch is made of 2mm thick steel plate and 8mm thick asbestos board riveted together. Due to the simple winding of the brake belt, there are significant differences in elastic deformation and stress states when the rotating drum is stopped. Analysis and practice have shown that the area near the brake head is prone to breakage. Through multiple innovation experiments conducted by several units, the heavy cast brake head was removed and the brake belt was divided into three sections and hinged together with a small shaft, resulting in a better effect. In this way, the elastic deformation of each section of the brake belt is relatively uniform, and it has a self-adjusting effect on the tightness of the brake wheel, which can extend the service life of the brake belt by more than five times.

　　The lack of flexibility in operating the brake is caused by improper adjustment of the brake lever and spring, or by impurities such as oil and dust on the brake wheel rim, which greatly reduces the friction force. If this situation is discovered, it is necessary to adjust the brake lever and spring in a timely manner, control the gap between the brake band and the brake wheel rim, and ensure that the braking stroke of the brake lever is within the range of 200-300 millimeters.
