Problems solved by technology

However, when the traditional oil cylinder is supplied, the spring of the oil cylinder is only designed with a braking stroke, but no pre-compression stroke (see figure 2 ); when the spring cylinder needs to be repaired or disassembled, because the brake cylinder is in a pre-tightened state, the spring is in a compressed state in the cylinder body, and the pre-tightened force is very large. Parts are easy to bounce off during the process, which has a high potential safety hazard

Embodiment 1

[0022] Such as figure 1 As shown, the spring cylinder for the winch of the present embodiment 1 includes: a brake cylinder 1, a pre-compression cylinder 2 arranged in sequence, and an adjustment assembly 3 located on the pre-compression cylinder 2; the brake cylinder 1 It is suitable for providing a braking stroke a for the spring cylinder for the winch, so that the spring cylinder for the winch is in a braking state; The stroke is extended to the precompression cylinder body 2, so that the drawworks releases the braking state with the spring cylinder.

[0023] See figure 2 , The spring of the traditional oil cylinder is only designed with a braking stroke when it is supplied, but there is no pre-compression stroke, so the spring of the oil cylinder cannot be released, and the spring cylinder for the winch cannot be released from the braking state. The spring cylinder for the winch of the present embodiment 1 is suitable for extending the braking stroke to the pre-compressi...

Embodiment 2

[0030] On the basis of Embodiment 1, Embodiment 2 also provides a winch equipped with the aforementioned spring cylinder for the winch.

[0031] When the spring cylinder for the winch is removed, the braking stroke of the spring cylinder for the winch can be extended to the pre-compression cylinder body through the adjustment component, so that the spring cylinder for the winch can release the braking state, which is convenient for maintenance of the spring cylinder for the winch and reduces the size of the winch Safety hazards under braking.

[0032] For the specific structure and implementation process of the spring cylinder for the drawworks, please refer to the relevant discussion in Embodiment 1, which will not be repeated here.

Embodiment 3

[0034] On the basis of Embodiment 1, this Embodiment 3 also provides a working method of the spring cylinder for the winch, that is, when the spring cylinder for the winch is removed, the braking stroke of the spring cylinder for the winch is extended to the pre-compression through the adjustment assembly In the cylinder, the spring cylinder for the winch is released from the braking state, which is convenient for maintenance of the spring cylinder for the winch.

[0035] For the specific structure and implementation process of the spring cylinder for the drawworks, please refer to the relevant discussion in Embodiment 1, which will not be repeated here.

[0036] In summary, the spring cylinder for the winch and its working method, the winch extends the braking stroke of the spring cylinder for the winch to the pre-compression cylinder body through the adjustment assembly, so that the spring cylinder for the winch releases the braking state, and the spring is adjusted. The for...

Abstract

The invention belongs to the technical field of mechanical equipment, and particularly relates to a spring cylinder with a braking function for a winch, a working method of the spring cylinder and the winch. The spring cylinder for the winch comprises a braking cylinder body, a pre-compression cylinder body and an adjusting assembly located on the pre-compression cylinder body, wherein the braking cylinder body, the pre-compression cylinder body and the adjusting assembly are arranged in sequence communication. The brake cylinder body is suitable for providing a brake stroke for the spring cylinder for the winch, so that the spring cylinder for the winch is in a brake state; and the adjusting assembly is suitable for extending the braking stroke to the pre-compression cylinder body, so that the spring cylinder for the winch is released from the braking state, the force of a spring is released, and the spring cylinder for the winch is convenient to maintain and disassemble.

Description

[0001] This application is a divisional application, the application number of the original application is 201911174981.0, the application date is: November 26, 2019; the name of the invention: spring cylinder for winch and its working method, winch. technical field [0002] The invention belongs to the technical field of mechanical equipment, and in particular relates to a spring cylinder for a winch, a working method thereof, and a winch. Background technique [0003] The marine winch is in the braking state when it is not working, so the brake cylinder must be in the pre-tightening state when it is not working, that is, the pre-tightening stroke is greater than the braking stroke. However, when the traditional oil cylinder is supplied, the spring of the oil cylinder is only designed with a braking stroke, but no pre-compression stroke (see figure 2 ); when the spring cylinder needs to be repaired or disassembled, because the brake cylinder is in a pre-tightened state, the...
