In the process of starting the motor 2 to work and descend the forming die, the electromagnet 27 is electrified at the same time, as shown in fig. 5, after the electromagnet 27 is electrified, an upward force is applied to the iron block 28 through electromagnetic attraction and is attracted and fixed with the iron block 28, so that the iron block 28 drives the friction disc 29 to rotate clockwise around the pin shaft 30 and separate from the pull rope 6, and simultaneously compresses the spring II 26, so that the spring II 26 obtains a restoring force, further, the hanging rod 4 applies a pulling force to the pull rope 6 in the downward moving process, so that the pull rope 6 drives the winding reel 7 to rotate and pay off, and the winding reel 7 applies a torque to the winding spring 10, so that the winding spring 10 obtains a restoring force, in the upward moving process of the hanging rod 4, the winding rope 6 is wound under the restoring force of the winding spring 10, the loosening of the winding rope 6 is avoided, when the swinging amplitude of the hanging rod 4 is larger in the upward and downward moving process, as shown in fig. 3, the pulling force of the suspension rod 4 on the pull rope 6 is increased, so that the pull rope 6 applies a downward pressure to the second slide rod 19 through the first wire guide wheel 16, so that the second slide rod 19 drives the second piston plate 22 to move downward and stretches the first spring 20, so that the first spring 20 obtains a restoring force, meanwhile, the second piston plate 22 pushes hydraulic oil in the first slide tube 21 into the first slide tube 14 through the guide tube 15, the first piston plate 13 drives the toothed plate 11 to engage with the gear ring 8 through the first slide rod 12, so that the winding tube 7 is stopped through the gear ring 8, the continuous output of the pull rope 6 is avoided, the shaking of the suspension rod 4 is prevented, after the suspension rod 4 is stabilized, the second piston plate 22 moves upward under the restoring force of the first spring 20, and a sucking force is generated in the second slide tube 21, so that the hydraulic oil in the first slide tube 14 flows back into the second slide tube 21 through the guide tube 15, therefore, the first piston plate 13 drives the toothed plate 11 to be separated from the gear ring 8 through the first slide rod 12, so that the boom 4 can move up and down normally again, and the purpose of improving stability and safety of the boom 4 during lifting is achieved.
When the motor 2 is stopped to lift the suspension rod 4, the electromagnet 27 is powered off simultaneously, as shown in fig. 4, the electromagnet 27 has no electromagnetic attraction to the iron block 28, so that the friction disc 29 is tightly attached to the pull rope 6 under the action of the restoring force of the spring II 26, when the suspension rod 4 suddenly falls down or shakes in the moving process, the suspension rod 4 applies a pulling force to the pull rope 6, so that the pull rope 6 drives the friction disc 29 to rotate anticlockwise around the pin shaft 30 through the friction force, the pull rope 6 with larger force of the friction disc 29 is tightly pressed, so that the pull rope 6 cannot be pulled out, the effect of preventing the suspension rod 4 from shaking is achieved, the stability and the safety of the suspension rod 4 in the transferring process are improved, and the whole lifting device is favorable for improving the qualification rate of the slurry forming of the large-block relief porcelain plate and achieving better quality.
