The method of manually inserting the steel wire rope with six strands of fiber core or metal core alternately into the collar hanger is also suitable for the collarless hanger.
way
1?
After five times of penetration, a plug joint is formed, and the five times of penetration can be composed of three times of integral penetration and two times of reduced penetration. 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 wire rope.
2? Interpolation should be carried out in a way of one share up and one share down.
3?
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.
4?
If the wire rope has an independent core, the core should be divided into three parts, namely:
-Two stocks;
-Two stocks;
-Two stocks plus its core.
These three parts are inserted with three staggered tails and only pass through three complete insertion points.
5?
If the wire rope has an independent steel strand core, when inserting into the first group, this strand core should be folded inward and then completely inserted into the center of the insertion head five times.
6?
All penetrations shall be fastened firmly until they are consistent with the center line of the inserted wire rope. In order to make the inserted parts smooth and round, it is necessary to shape them with appropriate tools so that they can enter the appropriate position.
prepare
1? The drill collar should be clamped in a vise, and the wire rope should pass through the drill collar so that the main part of the wire rope is on the right and the free end is on the left.
2?
Wire ropes should be tied at the top and both sides of the collar, or fixed with collar clips.
3? Untie a few strands of wire rope. The strand ends of steel wire ropes that have not been pre-deformed shall be firmly bound.
4?
The arrangement of wire rope and collar should be as shown in Figure A 1. ?
Initial stage of insertion
The initial insertion method is shown in Figure A2 and detailed in Table A 1.
The fourth group and the fifth group are interspersed.
A5. 1? After inserting the third group, some steel wires can be cut from each strand to reduce the tail end. The center of the remaining steel strand should be twisted into a steel strand with fewer steel wires.
In the structure.
A5.2? According to the method specified in A2.2 or A2.3, the fourth group and the fifth group should be inserted into the reduced tail end .. in order to make the inserted parts smooth and smooth and suitable.
When the tools are reshaped, they are brought into place.
