Embodiment

[0037] like figure 1 Shown is a multifunctional clamp mechanism for steel wire ropes, including a steel wire clamp, a tractor, a gathering clamp and a wire rope binding machine;

[0038] Wire clamps (such as Figure 2-6 shown) includes an upper fixture and a lower fixture. The upper fixture is provided with several first grooves arranged side by side, and the lower fixture is provided with several second grooves arranged side by side. The first grooves and the second grooves can be jointly form a clamping cavity for the steel wire to pass through; specifically, the lower surface of the upper clamp includes a first curved surface with several different radians, and the first groove is arranged along the length direction of the first curved surface; the upper surface of the lower clamp is provided with a a second curved surface with the same curved surface, and the second grooves are arranged along the length direction of the second curved surface;

Abstract

The invention belongs to the field of steel wire performance testing devices, in particular to a clamping method of a clamp for a steel wire rope. The clamping method comprises the following steps of conveying a steel wire by an external wire feeding mechanism; arranging a lower clamp on a wire feeding outlet of the external wire feeding mechanism; sending out a section of the steel wire by the external wire feeding mechanism; using a first pneumatic cylinder to push an upper clamp and enabling a first groove and a second groove to form a clamping cavity; using the external wire feeding mechanism to continue to feed the wire until the length of the steel wire reaches the required length; using the first pneumatic cylinder to push the upper clamp, and enabling the upper clamp and the lower clamp to have a clamping force therebetween; sending the steel wires drawn by a traction machine respectively to a steel wire inlet of a gathering clamp, and binding the steel wires by a steel wire binding machine. According to the clamping method of the invention, not only can non-destructive clamping of the steel wire rope be realized, but also performance testing, cutting and binding of the steel wires can be realized.

Description

technical field [0001] The invention belongs to the field of devices for steel wire performance testing, and relates to a testing clamp, in particular to a clamping method for a steel wire rope clamp. Background technique [0002] Steel wire rope has good bending flexibility and load-bearing capacity, so it is widely used as traction cable for transportation machinery, hoisting cable for mining machinery, support cable for passenger cableway, load-bearing steel cable for cable-stayed bridge, etc. The bearing strength and service life of steel wire rope Longevity is very important to the safe operation of these application equipment. During the operation of these equipment, the steel wire rope is subject to repeated stretching and bending and dynamic loads, so that the internal strands of the steel wire rope and between the steel wires are subject to fretting wear of different fretting amplitudes, and they must also withstand alternating vibrations. stress. Smaller fretting...
