Immersed tube transverse moving, mooring and cable tying tripper and cable tying and cable loosening method thereof

Abstract

The invention relates to the technical field of water construction rigging equipment, in particular to an immersed tube transverse moving, mooring and cable tying tripper and a cable tying and cable loosening method thereof. The cable tying tripper comprises a tripper body and a tripping arm which comprises a connection end and a hook end used for hooking and cable tying; the hook end is hinged toon end of the tripper body; the other end is connected with the other end in a detachable manner, and can rotate around the hook end; a connection structure is further arranged at the other end of the tripper body; and the portion, making contact with a belt dragging mooring rope, of the hook end of the tripper arm is of an arc-shaped structure. During cable tying, the tripping arm rotates aroundthe tripper body to be opened, the belt dragging mooring rope can easily penetrate into the tripping arm, the tripping arm is closed, and a tripping buckle shackle is buckled to achieving cable tying; when belt dragging cable loosening is completed, the tripping buckle shackle is manually knocked on, the tripping arm is automatically opened under the acting force of the self weight of a mooring rope, and cable loosening is successfully completed. The problems that cable tying frequently happens to a large steel wire rope, and fast cable loosening is difficult are solved, the labor intensity for cable tying of a worker is greatly reduced, and the work efficiency of the worker is improved.

Description

technical field [0001] The invention relates to the technical field of rigging equipment for water construction, in particular to an immersed tube laterally moving mooring cable release device and a method for tying and uncableping the cable. Background technique [0002] During the construction process of the immersed tube tunnel, it is necessary to haul the prefabricated immersed tube joints to the construction site for installation, and the process of lateral movement, mooring, docking and opening and closing of the immersed tube joints requires multiple rapid Unmooring and cable changing, while the pipe joints move laterally, and the mooring steel wire rope is thick, long and heavy (the diameter of the steel wire rope reaches more than 40mm), it is difficult to drag by manpower, and there is no power on the pipe joints. [0003] Existing various uncoupling devices for hoisting are only suitable for hoisting operations, and the decoupling action mostly adopts the principl...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an immersed tube in view of the problems that the uncoupling device used in the prior art is difficult to be applied to the water construction environment, and there are difficulties in carrying and untwisting the cable, and the towing cable hook is easily broken when hooked on the decoupling device. Transverse mooring cable release device and its method for carrying and untwisting the cable. The release device solves the problem of frequent cable loading and untwisting of large steel wire ropes by arranging the release device body and the release arm, and greatly reduces the burden on workers. The labor intensity of the cable is improved, and the work efficiency of the workers is improved
