Description

Technical Field

[0001] The utility model relates to a grinding mill slow transmission control device, belonging to the technical field of grinding mills. Background Art

[0002] A slow-motion device is an essential tool for mills operating at low speeds. It is primarily used for mill maintenance, liner replacement, and loosening materials to prevent overloading during long-term mill shutdowns. Traditional mill slow-motion devices primarily consist of a motor, reducer, clutch, and pull rod. During operation, the high- and low-pressure oil stations are typically activated first, followed by an injection device, a centralized control cabinet, and a self-test system. Once no faults are detected, the motor is started, which drives the reducer. The reducer then transmits its power to the push rod via the clutch, causing the mill to rotate slowly. The control process requires on-site personnel, is complex, and has low operational efficiency, making it unsuitable for larger mills. Therefore, a remote, efficient, and safe slow-motion control device is needed. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a grinding mill slow transmission control device in view of the defects in the prior art, so as to improve the slow transmission control operation efficiency.

[0004] To solve this technical problem, the utility model provides a mill slow transmission control device, including a remote control, a clutch hydraulic station, a cylinder, a gear coupling, a push rod, a traction support, a locking support and a base. The clutch hydraulic station is connected to the cylinder through an oil pipeline, the push rod is connected to the gear coupling, the left end of the cylinder is fixed to the traction support by bolts, and the right end of the cylinder is hinged and fixed to the top of the push rod. The remote control sends remote control commands to control the start and stop of the clutch hydraulic station, and controls the extension and retraction of the cylinder through the hydraulic pressure inside the clutch hydraulic station, thereby controlling the forward and backward swing of the push rod, so that the push rod controls the closing and disengagement of the gear coupling, and finally realizes the control of the start and stop of the entire slow transmission device.

[0005] The left end of the locking support is positioned on the traction support through a bolt, and the right end of the locking support is fixed on the push rod through a bolt, playing the role of locking the push rod.

[0006] The oil cylinder is provided with an oil inlet hole and an oil return hole, and the oil inlet hole and the oil return hole are connected to the clutch hydraulic station through an oil pipeline.

[0007] The gear coupling and the push rod are connected in an embedded manner.

[0008] The bottom of the push rod is hinged and fixed on the base 8.

[0009] The remote control controls the clutch hydraulic station via wireless signal transmission instructions, and the instructions include slow transmission start and slow transmission stop; when the slow transmission start instruction is issued, the clutch hydraulic station supplies oil to the oil inlet hole of the oil cylinder through the oil pipeline, and the oil cylinder retracts the push rod due to the internal pressure, causing the push rod to swing forward, pulling the gear coupling forward and closing, thereby starting the entire slow transmission device; when the slow transmission stop instruction is issued, the oil cylinder returns to the clutch hydraulic station through the oil pipeline of the return oil hole, and at the same time, the oil cylinder pushes out the push rod due to the internal pressure, causing the push rod to swing backward, pulling the gear coupling backward and disengaging, thereby stopping the entire slow transmission device.

[0010] Beneficial effect: The utility model controls the start and stop and forward and reverse rotation of the ball mill slow transmission device by remote control, which is more responsive and safer, and greatly improves the slow transmission control efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
