[0002] In the mining, ore dressing, coal preparation, metallurgy, chemical industry, and building materials industries, electric motors, reducers, and claw couplings are usually used as driving components of the ball mill slow drive system to drive the ball mill cylinder to rotate slowly. During the maintenance of the ball mill, it is necessary to manually rotate the reducer input shaft to drive the main shaft and driven shaft of the claw coupling to align, and then use a hammer to hit the push rod above the claw coupling to engage the claw coupling, and then use the control motor to drive the ball mill slowly. This maintenance operation requires two operators to assist each other and frequently operate the above steps. The safety factor is low during the operation, the labor intensity of the operators is high, the efficiency is low, and the operation time is long. Utility Model Content

DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0016] like Figure 1 As shown, a claw coupling automatic alignment and engagement system includes an electromagnetic brake three-phase asynchronous motor 1, a coupling, a planetary transmission 3, a cylinder 11, a claw coupling, a photoelectric sensor, an induction metal plate 9, a proximity switch 10 and a PLC control system.

[0017] The motor shaft of the electromagnetic brake three-phase asynchronous motor 1 is connected to the planetary transmission 3 through a coupling, so that the motor drives the planetary transmission 3 to rotate at a reduced speed. The output end of the planetary transmission 3 is installed with a claw coupling main shaft, and a gate bracket 4 is installed on both sides of the main shaft sleeve. The gate bracket 4 is fixedly connected to the sleeve. A cylinder 11 is connected between the planetary transmission 3 and the gate bracket 4. The cylinder 11 is used to push the claw coupling main shaft 5 to make axial movement.

[0018] The driven shaft 7 of the claw coupling is installed on the rotating shaft section of the equipment and is used to drive the equipment after engaging with the main shaft of the coupling; an optical sensor transmitting end 6 is installed on the main shaft 5 of the claw coupling, and an optical sensor receiving end 8 is installed on the driven shaft 7 of the claw coupling to position the straight rulers of the main and driven shafts of the claw coupling; it also includes a proximity switch 10 installed on the main shaft 5 of the claw coupling and an induction metal plate 9 correspondingly installed on the driven shaft 7 of the claw coupling to confirm whether the main and driven shafts of the claw coupling are engaged.

[0019] The PLC control system is signal-connected to the cylinder 11, the optical sensor transmitting end 6, the optical sensor receiving end 8, the proximity switch 10 and the induction metal plate 9, and the PLC control system is used to control the action of the cylinder 11.

[0020] When the present utility model is in use: after an operator starts the slow drive system, the electromagnetic brake three-phase asynchronous motor 1 starts and drives the planetary transmission 3 and the main shaft 5 of the claw coupling to rotate clockwise. When the optical sensor transmitting end 6 is aligned with the optical sensor receiving end 8, the electromagnetic brake three-phase asynchronous motor 1 stops, and the optical sensor sends a straight tooth centering instruction of the main and driven shafts of the claw coupling to the PLC. After 5S of timing, the PLC sends an instruction to the cylinder 11, the solenoid valve acts, and the cylinder 11 drives the gantry bracket 4 outside the main shaft 5 of the claw coupling through the piston to push the main and driven shafts of the claw coupling to engage. When the proximity switch 10 detects the induction metal plate 9 in place, it sends the meshing state information of the main and driven shafts of the claw coupling to the PLC. After 5S of timing, the PLC sends a start signal to the electromagnetic brake three-phase asynchronous motor 1, and the electromagnetic brake three-phase asynchronous motor 1 can drive the equipment to rotate clockwise through the reducer and the claw coupling.
