Background technique

Metallurgical cranes are special equipment, and safety in use is particularly important. Wire ropes, as the key tool for lifting, need to be replaced regularly according to the use cycle and situation. When replacing the wire rope, it usually takes 5 people and 2 forklifts (or shovel trucks) to release the new wire rope from the rope drum by dragging. Releasing the new wire rope manually alone requires a relatively large site (300 meters of wire rope requires a 300-meter-long site). Due to the large site, there will be certain safety hazards when there are trucks entering and leaving the road. Due to the limitation of the site, the measurement error of the wire rope is large. The operation time is seriously too long, and the work takes more than 8 hours. Because the wire rope is heavy, more manpower is required, and the work efficiency is low.

Step 2, releasing the wire rope 9: starting the motor 1, the motor 1 drives the second reel 4 to rotate forward to recover the traction rope 6. Under the traction of the traction rope 6, the first reel 3 releases the wire rope 9 by rotation. The first traction rope 6 pulls the wire rope 9 to wrap five circles around the two pulleys 7, completing the release of the wire rope 9.

Step 3, recovering the wire rope 9: as shown in Figure 2, when the wire rope 9 wound on the two pulleys 7 reaches the specified length, cut the wire rope 9, connect the wire rope 9 wound on the pulley 7 to the third reel 5, start the motor 1, and drive the third reel 5 to rotate in the opposite direction. The rotation of the third reel 5 causes the wire rope 9 to be wound on the third reel 5, and at the same time, the traction rope 6 on the second reel 4 is rewound on the two pulleys 7 to complete the recovery of the wire rope 9. After the recovery of the wire rope 9 is completed, disconnect the second reel 4, the third reel 5 and the reducer 2 in turn, and use the wire rope 9 on the third reel 5 to replace the wire rope 9 for the driving.
