The method of fastening connection on top of stainless steel wire rope
In many applications, the top of the stainless steel wire rope needs to connect the accessories, and the wire rope and accessories safe Connection way for its safe use is very necessary, then we must take some specific method to the top of the stainless steel wire rope fastening connection. Here are some common ways to do this:
(1) Knitting method.
In the actual production life, the most common fastening method is the knitting method, using the heart-shaped sleeve ring to fold the stainless steel wire rope, and the end of the strands of wire rope into the rope body, repeated $number times, and finally tied or with head tightly to the line. During operation, the length of strapping is not less than 20 times times the diameter of stainless steel wire rope to ensure safe use.
(2) card head fixed.
Head is a special tool for fixing stainless steel wire ropes. At the end of fixed stainless steel wire rope, using the knitting method to fasten the sleeve ring, then use head to tighten it. When fixed, according to the diameter of stainless steel wire rope, should be equipped with corresponding number of card head. Wire rope diameter In the 7~18mm should be equipped with 3 chuck, 19~27mm should be equipped with 4 card head, 28~37mm should be equipped with 5 chuck, 38~45mm should be equipped with 6 headers. Also, to ensure that the tensile strength of the card head should not be less than 80% of the breaking tensile force of stainless steel wire rope, the rest should be operated according to the stainless steel wire rope using method.
(3) Alloy pressure head method.
First of all, the end of the stainless steel wire rope in accordance with the pressure of the unit to split, and each share of the first spare. The length of the split can not exceed the length of the alloy sleeve, and then the top of the wire rope bending out of the appropriate hole, all the separate rope strands inserted into the line, the final set into the aluminum cable sleeve compaction can be.
(4) Detachable joint.
The main use of this method is the wedge sleeve, the wire rope can be used to connect the wedge after the construction. However, this method can only guarantee the breaking tensile force of the wire rope around 90%.
Have you learned these methods? Although the top of the stainless steel wire rope fastening method is relatively simple and easy, but in order to ensure the reliable use of stainless steel wire rope, everyone in the top fastening connection must be the relevant details are perfect, in line with the safety requirements.
