The flexible rope tension-displacement measurement and control and crimping equipment includes a machine base, a rope connection device and a man-machine interaction control box; wherein the rope connection device includes a displacement drive module, a tension drive module, a tension-displacement measurement and control module, and a compliance crimping module; the displacement drive module is used for adjusting the length of the rope; the tension drive module is used for adjusting the tension of the rope; the tension-displacement measurement and control module is used for measuring and controlling the length and tension of the rope; and the compliance crimping module is used for completing the compliance centered crimping of a jacket. Through the simultaneous action and cooperation of the displacement drive module, the tension drive module, the tension-displacement measurement and control module and the compliance crimping module, the force-displacement hybrid measurement and control of the flexible rope connection is realized; and therefore, the problem of difficult to control the accuracy caused by factors such as small strain ratio and length-tension coupling in the rope manufacturing process is effectively overcome, and the accuracy and efficiency of rope measurementand connection are improved.

Description

technical field [0001] The invention belongs to the field of production of flexible ropes, in particular to a tension-displacement measurement and control and crimping equipment of flexible ropes. Background technique [0002] The flexible rope structure is an important part of the flexible cable net structure, which consists of a fiber braided rope with low elongation and small thermal expansion coefficient, two node parts for fixing the end position of the braided rope and two pieces for crimping braided It consists of a metal pipe jacket at the end of the rope. [0003] Each end of the fiber braided rope is inserted into the metal pipe jacket in a forward direction, passes through the rope hole of the node part, and passes out of the metal pipe jacket in the reverse direction; The jacket, thereby fixing the length and tension value of the braided rope, completes the production of a specific length-tension flexible rope. [0004] At present, the wire rope material of the...

AI Technical Summary

Problems solved by technology

Due to the wide range of elastic modulus of the fiber braided rope and the braiding gaps in the rope body, the tension and deformation of the Kevlar fiber braided rope do not satisfy the linear relationship when tensioned, that is, they do not satisfy Hu Ke's law

And because the theoretical strain of each piece of flexible rope is small, a small length error will have a great impact on the tension of the rope

Therefore, when making flexible ropes, it becomes extremely difficult to achieve high precision in rope length and tension at the same time

[0005] At present, the production of flexible rope structures is mainly done by hand with manual tooling, which not only has a large workload and low efficiency, but also cannot meet the high precision and consistency requirements of flexible ropes, which seriously hinders the development of ropes and cable nets.
