[0030] Working process:
[0031] Before use, the first glass fiber shell 2 and the second glass fiber shell 3 are placed on the outside of the large hook body 1. Since the first engaging groove 4 and the second engaging block 6 are engaged, and the first engaging block 5 and the second engaging groove 7 are engaged, the first glass fiber shell 2 and the second glass fiber shell 3 can be tightly fitted on the outside of the large hook body 1. The first glass fiber shell 2 and the second glass fiber shell 3 are made of glass fiber material, which has the characteristics of good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, so they can better protect the large hook body 1. Then, the rubber sleeve 9 is put on the first glass fiber shell 2 and the second glass fiber shell 3. The first and second glass fiber shells 2 and 3 are fixedly connected to the positioning shaft 8 on the outside of the hook body 1. The rubber sleeve 9 is made of a soft insulating rubber material, and a positioning groove 10 is provided on the inside of the rubber sleeve 9. Therefore, the rubber sleeve 9 can be sleeved on the outside of the first and second glass fiber shells 2 and 3 in a fixed direction, so that the first and second glass fiber shells 2 and 3 can be fixed on the outside of the hook body 1. The rubber sleeve 9 is made of an insulating rubber material, which is soft, highly elastic, well coated, and highly insulating, and can well make up for the first and second glass fiber shells 2 and 3. The shell 3 has poor wear resistance, and then the fixing tube 12 is sleeved on the outside of the top of the large hook body 1, and the inner side of the fixing tube 12 can fit with the outer side of the large hook body 1, and the fixing groove 13 can separate the lower side of the fixing tube 12 into two parts, the bottom end of the inner circle part of the lower side of the fixing tube 12 fits with the top of the first fiberglass shell 2 and the second fiberglass shell 3. At the same time, the fixing tube 12 receives the upper part of the rubber sleeve 9 through the fixing groove 13, and the upper part of the rubber sleeve 9 is provided with a fixing hole 11, and the fixing bolt 15 passes through the fixing hole 11 and is screwed with the fixing tube 12 through the threaded hole 14, and the fixing The rubber sleeve 9 is fixed to prevent the rubber sleeve 9 from separating from the first glass fiber shell 2 and the second glass fiber shell 3. The device protects the large hook body 1 through the first glass fiber shell 2 and the second glass fiber shell 3, and fixes the rubber sleeve 9 to the outside of the first glass fiber shell 2 and the second glass fiber shell 3 through the fixing tube 12, which plays an insulating, anti-static and anti-wear role, and can avoid the wear of the large hook body 1 by the wire rope during the crane operation.
