Swing-oil-cylinder-type steel strand clamping device

Abstract

The invention provides a swing-oil-cylinder-type steel strand clamping device which comprises a bevel pressure disc, a clamping piece pressure disc, a clamping piece, a clamping piece seat, an upper end cover, an upper bearing, an upper supporting disc, blades, a lower end cover, a pressure spring sleeve, a pressure adjusting bolt, a steel strand, a bottom cover, a lower supporting disc, a lower bearing, a cylinder, a positioning block, a spring, a reset ring and an anti-rotating pin. A taper hole is formed in the top of the clamping piece seat and used for storing the clamping piece. The bottom of the clamping piece seat is connected with the bottom cover through a thread. The clamping piece seat is also a spindle of a swing oil cylinder, and through supporting pieces and positioning pieces such as the bearings, a clamping ring, the upper end cover and the lower end cover, the position of the cylinder in the axial direction of the spindle is determined. The bevel pressure disc is fixed to the upper end cover of the swing oil cylinder through screws, and makes contact with the clamping piece pressure disc through four bevels evenly distributed circumferentially. The anti-rotating pin is arranged between the clamping piece pressure disc and the clamping piece seat. The steel strand penetrates through the clamping device from bottom to top through holes corresponding to the bottom cover, the reset ring, the clamping piece and the clamping piece pressure disc. The swing-oil-cylinder-type steel strand clamping device is simple and compact in structure, convenient to machine andhigh in work reliability.

Description

technical field [0001] The invention relates to a steel strand clamping device, in particular to a swing cylinder type steel strand clamping device. Background technique [0002] The steel strand hydraulic synchronous lifting system has the characteristics of strong adaptability, easy control, small size and high efficiency, and has been more and more widely used in the field of sunken ship salvage. The steel strand clamping device is a key mechanism in the steel strand hydraulic lifting system, which has an important impact on the safety, reliability and efficiency of fishing operations. [0003] During the salvage process of the sunken ship, the steel strand clamping device needs to perform frequent operations of clamping and loosening the steel strand. Due to the particularity of shipwreck salvage operations, there are high requirements for the reliability and work efficiency of the steel strand clamping device. The existing steel strand clamping device has the followin...

AI Technical Summary

Problems solved by technology

[0004] 1. The structure is complex and the volume of the clamping device is too large;

[0005] 2. The reliability of long-term continuous work is poor;

[0006] 2. Clamping is unreliable, and it is prone to the situation that only part of the clip is stressed;

[0007] 3. It is difficult to reset the clip, and the friction between the clip and the taper hole is too large
