1, wedge sleeve fixation method. One end of the wire rope bypasses a special inclined wedge, and the wire rope is fixed by the locking function of the wedge in the sleeve, and the strength of the fixed position is about 75%-85% of the strength of the wire rope itself.
2. Conical sleeve fixing method. After the end of the steel wire rope passes through the tapered sleeve, the head steel wire is bent into a small hook and poured with lead or zinc liquid for solidification, and the strength of the fixed position is roughly the same as that of the steel wire rope itself.
3, rope card fixation method. The wire rope is sleeved on the heart-shaped ring and fixed with a special wire rope clamp. The bottom plate of the wire rope clamp should be buckled on the working section of the wire rope, and the U-shaped bolt should be buckled on the tail of the wire rope. The number of wire rope clamps shall not be less than 3.
4. Weaving method. Use a heart-shaped return. After one end of the wire rope bypasses the coupling, each strand is braided and inserted into each branch pipe, and each strand is interspersed for 4-5 times, and then tied tightly with thin steel wire. The length of the wire rope is 20-25 times the diameter of the wire rope, and it should not be less than 300 mm at the same time. The strength of the fixed position is 75%-90% of the wire rope itself.
5. Aluminum alloy indenter method. After the wire rope ends are disassembled, they are divided into six strands, and the ends of each strand are staggered. The end length shall not exceed the length of aluminum sleeve, and the rope core shall be cut off. After bending 180, insert the main rope with a drill, then insert the lead sleeve, press it into an oval shape on a steam hammer, and then press it into shape with a press. This method has the advantages of good processing technology, light weight and convenient installation, and is often used as a fixed cable for cranes.
Second, the wire rope weaving steps
1. Insert the steel wire rope with six fiber cores or steel wire rope cores alternately by hand, and make the steel wire rope connecting device with the collar.
2. After five times of interpenetration, the plug joint is made, and the five times of interpenetration can be composed of three times of whole strand interpenetration and two times of reduced strand interpenetration. All joints shall be opposite to the winding direction of wire rope; Except for the first group, the tail ends of all strands inserted in other groups should be opposite to the twisting direction of the original wire rope.
3. Interleaving should be carried out in a way that one stream crosses upward and the other stream crosses downward.
4. If the wire rope has a fiber core, the core should be completely penetrated with the first end of the first group, and then the exposed core should be cut off. If the strand has a fiber core, the core of the strand should remain in the original strand.
5. If the wire rope has an independent core, the core should be divided into three parts. They are:-two stocks,-two stocks, and-two stocks with their core. Three staggered ends are used to insert these three parts, and they only pass through three complete joints.
6. All interpenetration shall be fastened firmly until it is consistent with the center line of interpenetration wire rope. In order to make the inserted parts smooth and round, it is necessary to shape them with appropriate tools to make them enter the appropriate position.
