Technical Field
[0001] This utility model relates to the field of coal conveyor belt technology, specifically to a disc brake device equipped with a hydraulic tensioning component. Background Technology
[0002] A coal belt conveyor is a device used in industrial applications to transport coal or other materials from one location to another. It typically consists of a conveyor belt, drive unit, support structure, conveyor rollers, and other components. This type of equipment can efficiently transport large quantities of coal or other materials.
[0003] In coal mining and transportation, belt conveyors serve as crucial equipment connecting underground and surface operations, and their safe and efficient operation is essential for ensuring coal mine production. Currently, belt conveyor systems suffer from safety hazards and outdated technology. The original equipment's disc brake hydraulic station lacks the function of automatically stopping the motor to maintain pressure after the pump station reaches its rated pressure, resulting in low safety performance and outdated technology. If the belt conveyor stops under heavy load and the backstop fails to brake effectively, reverse rotation of the belt is highly likely, posing a significant safety hazard. The hydraulic station motor operates continuously, leading to overheating and frequent malfunctions. Furthermore, the JH-20 return-column winch used for belt conveyor tensioning provides insufficient tension, failing to meet the rated speed requirements of the belt conveyor. Utility Model Content
[0004] The purpose of this utility model is to provide a disc brake device with a hydraulic tensioning component, which features an automatic motor shutdown and pressure-maintaining function after reaching rated pressure, achieving precise control of braking force, effectively preventing motor overheating and malfunctions. It can also automatically adjust the tension according to the belt conveyor's operating requirements, ensuring stable operation. Furthermore, it has a pressure protection function, automatically adjusting when the pressure exceeds upper or lower limits and maintaining pressure through an accumulator, improving the reliability and stability of the equipment. This solves the problems of the original disc brake hydraulic station lacking the automatic motor shutdown and pressure-maintaining function after the pump station reaches rated pressure, resulting in low safety performance and outdated technology; and the risk of belt conveyor reversal when the belt conveyor stops under heavy load and the backstop fails to brake effectively, posing a significant safety hazard. The hydraulic station motor is in a state of continuous operation, leading to frequent overheating and malfunctions.
