Cable tension buffer device

Abstract

The invention belongs to the field of marine machinery and discloses a cable tension buffer device. The cable tension buffer device comprises a bearing block and a pair of cable limit devices installed on the bearing block, wherein the cable limit devices and the bearing block are in sliding fit; the pair of cable limit devices are symmetrically arranged at the two ends of the bearing block and fixedly connected with one end of a hydraulic expansion link; the other end of the hydraulic expansion link is connected with a hydraulic buffer system. The cable tension buffer device provided by the invention uses the own cable limit devices to fix an iron chain, and the hydraulic expansion link transfers the force born by the cable limit devices, so as to weaken the impact due to the sudden pull by the cable, effectively protect the structural safety of the iron chain joints of towing ships and towed ships or marine engineering equipment and reduce sudden impact.

Description

technical field [0001] The invention relates to the field of marine machinery, in particular to a cable tension buffering device. Background technique [0002] One of the important tasks of offshore engineering vessels is towing operations. Iron cables are required for towing operations. In actual operations, due to changes in the hull motion caused by the influence of waves, the iron cables often produce sudden pulls, impacting the towed vessel and the towed vessel. The cable fixing mechanism of the towing ship not only affects the structural safety of the ship, but also affects the safety of deck operators. At present, reinforced shark jaws are often used to withstand the sudden pull of the iron cables. The tail structure of the hull and the shark jaw structure are still Will be subject to a greater impact, did not effectively solve the problem. Contents of the invention [0003] The purpose of the present invention is to overcome the defects and deficiencies in the pri...

[0002] One of the important operations of the ocean engineering vessel is the towing operation. The towing operation requires the use of iron cables. In actual operations, due to the influence of waves, the movement of the hull changes, and the iron cables often produce sudden pulls, impacting the towed vessel and the towed vessel. The cable fixing mechanism of the towed ship not only affects the structural safety of the ship, but also affects the safety of deck operators. At present, reinforced shark jaws are often used to withstand the sudden pull of the iron cables. The structure of the tail of the hull and the shark jaw structure are still Will be subject to a greater impact and have not effectively solved the problem
