Cable tension releaser and use method thereof

Abstract

The invention discloses a cable tension releaser, and belongs to the technical field of cable protection equipment, the cable tension releaser comprises a shell, a buffer part and a release part, the shell comprises a shell I and a shell II, and the shell I and the shell II are connected through an external snap bolt; the buffer component comprises an outer snap bolt and a buffer rope, and the release component comprises an extension spring, an inner shell and an inner snap bolt; the inner shell and the second shell are fixedly connected through an inner snapping bolt, a first pin shaft is arranged in the buffer shell, an extension spring is arranged between the first pin shaft and the second pin shaft, and the two ends of the extension spring are fixed to the first pin shaft and the second pin shaft respectively; a third connecting piece is arranged on the left side of the inner shell and fixedly connected with the right end of the buffer rope, a first connecting part is arranged on the left side of the first shell, the right side of the first connecting part is fixedly connected with the buffer rope, and the right end of the buffer rope is fixedly connected with the third connecting piece. The ship cable can be prevented from being suddenly snapped, and the product is mainly applied to a mooring rope.

Description

technical field [0001] The invention belongs to the technical field of cable equipment, and in particular relates to a cable tension releaser and a using method thereof. Background technique [0002] During the berthing operation, the ship often drifts away, or the cable hook system equipment fails to be released normally. At this time, the cable will suddenly break under the strong pull of the ship. This is very dangerous. The cable breaks lightly. Affect the normal operation, serious will cause equipment damage or even casualties, does not meet the safety regulations of the ship; if the cable hook system equipment failure usually use an ax to manually cut the cable, at this time the person who cut the rope will also be threatened to a certain extent, there is a lot of danger. great danger. [0003] Patent application number: 92222781.0 discloses a marine cable buffer, which is composed of cable rings at both ends and a buffer body in the middle. The sleeve pipe (3) is fo...

Problems solved by technology

The utility model can reduce the tension of the marine cable, reduce accidents such as cable breaking, and is light in weight and sufficient in elasticity. It can reduce the load of towed navigation at sea, increase the speed of the ship, and ensure the normal navigation and the safety of the cable. However, the above patent has the following defects: The patent can only be used for stretching between two ships, and cannot be used on the cable when the ship is docked, because when it is used on the cable, it can only perform simple preliminary buffering. When the initial buffering is over, this The cable that hangs on the cable release hook is still hanging on the cable release hook. When it is dragged by a greater pulling force, the cable release hook will be damaged, or the cable will be directly broken to form a cable release. At this time, it will cause a safety hazard; at the same time, this utility model cannot solve the problem of sudden breaking of the cable, and we need a more powerful cable safety device to replace the existing technology
