Towline winch with brake structure

Abstract

The invention discloses a towing winch with a brake structure. The towing winch comprises a drum, a brake strap is arranged on the outer side of the drum, a jacking device is arranged below the brake strap and comprises a first bracket, a pulley is arranged on the first bracket, a pull rod of the brake strap comprises connecting portions on two sides, a second screw hole and a third screw hole with thread directions opposite are formed in the two connecting portions, a third screw is arranged in the second screw hole and the third screw hole, thread directions on two sides of the third screw are opposite, a ratchet is further arranged on the drum, and the towing winch further comprises a clamping block matched with the ratchet. When the brake strap is about to loosen, the top of the brake strap is prevented from clinging to the drum to be difficult to separate due to influence of self gravity; due to the pulley, friction between the jacking device and the brake strap is reduced; length of the pull rod can be adjusted through the third screw; after the drum stops through the brake strap, the ratchet is clamped with the clamping block, so that the drum is prevented from rotating to cause danger when not in work.

Description

technical field [0001] The invention relates to marine equipment, in particular to a tow cable winch, in particular to a tow cable winch with a brake structure. Background technique [0002] The towline winch is a kind of marine equipment, which is used when the ship is towed. The general towline winch includes a hydraulic motor, a drum, a cable arrangement and a braking device. The winch braking device mainly plays the role of fixing and releasing the ship's cables. [0003] The braking device of the existing winch is generally a brake band, and the operation of the existing brake band generally relies on manpower to tighten and release the drum. This structure has the following problems: the brake is manually operated, and the braking of the drum is achieved through the speed of the manual screw rod and the strength of the worker. The strength of the worker and the speed of the screw rod usually cannot meet the needs of large-load ship machinery. The requirements of the ...

AI Technical Summary

Problems solved by technology

This structure has the following problems: the brake is manually operated, and the braking of the drum is achieved through the speed of the manual screw rod and the strength of the worker. The strength of the worker and the speed of the screw rod usually cannot meet the needs of large-load ship machinery. The requirements of the working conditions, and the workers are very dangerous when the screw is hand-cranked, and it is easy to cause safety accidents

[0006] After the drum is fixed with the brake band, the brake will be released, and the drum is not positioned after the brake is released, which may cause danger due to various reasons.
