Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] A kind of sample preparation method of the present invention is convenient to steel wire rope breaking tensile test, specifically carries out according to the following steps:

[0022] Step 1, select a section of steel wire rope, such as figure 1 As shown, the steel wire rope includes a central strand 5, and the periphery of the central strand 5 is provided with a plurality of inner layer strands 4, and the periphery of the inner layer strand 4 is provided with a second outer layer large strand 3 in contact with the inner layer strand 4, and the adjacent second outer layer large strands The sub-outer small strands 2 are arranged between the 3, and a plurality of outer strands 1 are arranged on the periphery of the sub-outer large strands 3 and the sub-outer small strands 2;

[0023] Step 2, binding the two ends of the wire rope with i...

Abstract

The invention discloses a sample preparation method for facilitating of test of breaking force of a rope. The method comprises the following steps that: two ends of a wire rope is bundled with iron wires, the outer strands at both ends of the wire rope are completely disassembled, and at the same time, part of the secondary outer large strands and secondary outer small strands are disassembled, the wire rope obtained in the step 3 is casted, and the casted wire rope is subjected to the test of breaking force. The sample preparation method for facilitating of test of breaking force of a rope reduces the workload of the preparation of samples for the test of breaking force of a rope by adopting the casting method, improves the qualified rate of the port position of the breaking force of therope and reduces the structure damaging of the wire rope generated by disassembling so as to effectively improve the compliance of the port position during the test of breaking force of the rope.

Description

technical field [0001] The invention belongs to the technical field of steel wire rope detection, and relates to a sample preparation method for the breaking force test of steel wire ropes. Background technique [0002] 35(W)×K7 type steel wire rope is a 3-layer strand 2-fold rope closing center structure, and the rest of the strands are compacted strands to resist rotation. There are 5-9 steel wires for the outer strands, and 4-8 outer strands for the outer strands. The root is a single-layer steel wire strand. The wire rope has remarkable characteristics such as good anti-rotation performance, high breaking force value, excellent softness and large contact area with the pulley (drum). The 35(W)×K7 wire rope is one of the typical structures of the 35(W)×K7 type wire rope . Compared with the single-layer steel wire rope, when the casting method is used to test the breaking force of the 35(W)×K7 steel wire rope, the steel wire rope is often broken in the fixture. According ...
