Types Of Wire Rope Clasp The Correct Use Of Wire Rope Clasp
First, the type of wire rope clip, also called wire rope clip.
Wire rope collet is mainly used for the temporary connection of wire rope and the fixing of the back hand rope when the wire rope goes through the block, as well as the fixing of the wind rope rope head on the raking rod, including phosphating coated wire rope, galvanized wire rope, stainless wire rope and smooth wire rope. It is a wide range of wire rope clamp used in lifting and hoisting operations. Usually used wire rope clip, there are riding type, fist grip type and pressure plate type 3. The riding card is even relay the strongest standard wire rope clip, the most widely used.
Secondly, the clamping type, because there is no base, easy to damage the wire rope, even the relay is poor, therefore, only used in the secondary place.
1, the choice of rope clip, U-ring side clear distance should be 1~3mm larger than the diameter of the wire rope, the clear distance will make the buckle connected in the card is not tight wire rope, resulting in sliding and accidents.
2. The bolts of the buckle must be tightened. Generally, the diameter of the wire rope shall prevail.
3, U-shaped part should be in contact with the wire rope head, can not be reversed with the main rope; Rope clamp installation should be straight, equidistant arrangement;
4. In order to check whether the rope clip joint is safe and reliable or timely find whether the steel wire rope joint part is sliding, generally add a rope clip about 500mm behind the last rope clip, and release a "safe bend" of the rope head; If the steel wire rope joint slides, the phenomenon of "safety bend" being straightened can be intuitively shown, and the treatment measures should be taken in time.
Three, wire rope clip installation standard wire rope clip used to clamp wire rope, then how many wire rope clip clamping wire rope need, wire rope clip how to install?
Generally speaking, the diameter of the wire rope is 7mm-16mm, which requires 3 rope clips; Wire rope diameter of 19mm-27mm need rope card 4; The diameter of the wire rope is 28mm-37mm. 5 rope cards are required. Wire rope diameter 38mm-45mm need rope card 6.
1. Due to operation safety requirements, the number of wire rope fasteners should be strictly referred to the following installation specifications.
2. The connection strength of the wire rope clasp shall not be less than 85% of the breaking tension of the wire rope.
3, the wire rope buckle should be installed on the long end of the wire rope side.
4. The spacing between each wire rope clasp should not be less than 6 times of the diameter of the wire rope.
