Problems solved by technology

At present, the cyclic pre-drawing process of ropes is generally carried out on horizontal tension machines. For rope products with large lengths, such as deep-sea buoy mooring cables with a length of 500 meters or longer, they can only be used on sites with larger spans. The vehicle applies tension to the rope for pre-stretching. This pre-stretching method has the problems of complicated operation, difficulty in accurately controlling the drafting force, and the rope is easy to be brushed and stained during the pre-stretching process, and there are safety hazards in the stretching process.

Abstract

The fiber rope pre-drafting device includes: a device platform; a first drafting assembly, which is installed on the device platform, and the first drafting assembly includes at least one first rotating part for drafting the fiber rope; a movable assembly, which is set On the device platform, it is arranged to be movable on the device platform; the second drafting assembly is arranged and installed on the movable assembly, and the second drafting assembly includes at least one second rotating part for drafting the fiber rope, the second The rotating part is arranged in parallel with the first rotating part, and the distance between them is set to be adjustable; the driving assembly is arranged to be connected with the second rotating part, and is used to drive the movement of the second rotating part, and adjust the distance between the first rotating part and the first rotating part. The distance; the tension detection assembly is configured to detect the tension applied to the fiber rope; wherein the fiber rope is arranged on the first rotating part and the second rotating part, by adjusting the distance between the first rotating part and the second rotating part To adjust the tension of the fiber rope.

Description

technical field [0001] The application belongs to the technical field of fiber ropes, and in particular relates to a fiber rope pre-drawing device and a pre-drawing method. Background technique [0002] The rope will elongate after being loaded, and the elongation at break is another most important performance index of the rope after the breaking strength and linear density. Newly made braided or twisted fiber ropes, due to their dense structure, tend to have a large elongation when a load is applied, and part of the elongation is irrecoverable, and this irrecoverable elongation is actually the length of the rope. Structural elongation. For rope products that require high dimensional stability, such as hoisting ropes, electric traction ropes, sailing ropes, deep-sea buoy mooring cables, single-point and multi-point mooring cables for floating production, storage and offloading (FPSO), etc., There is a need to eliminate structural elongation of the rope during production. ...
