Problems solved by technology

The main technical problem of the disc brake of the hoist in the prior art is: with the increase of the type of the hoist, for the disc brake of the hoist, it is necessary to increase the corresponding braking force to ensure the braking force of the disc brake. active
At present, in order to increase the braking force of the disc brake, it is necessary to increase the size of the disc spring and the thickness of the disc spring to increase the braking force of the disc brake. This will inevitably increase the weight and layout space of the disc brake, which will inevitably increase the The manufacturing cost of the type brake and the layout space of the brake

Abstract

The invention belongs to the technical field of driving braking of high-sensitivity brakes, and discloses a variable braking force device of a high-sensitivity brake. A brake cylinder body is a hollow cylinder with two closed ends, a first piston is fixedly arranged in a brake releasing cavity of the brake cylinder body, and a second piston is fixedly arranged at the position, close to the right side, of a brake rod. The left end of the brake rod is fixedly connected with the middle position of the right side of the first piston, and the right end of the brake rod penetrates through a brake cavity and extends out of the right side of the brake cylinder body. A brake shoe is fixedly arranged at the right end of the brake rod. The brake releasing cavity is fixedly formed in the left side of the brake cylinder body, and the brake cavity is fixedly arranged on the right side of the brake releasing cavity. Under the working condition that the size of the brake is not changed, the braking force can be improved, the machining precision of the brake is improved, and the manufacturing cost of the brake is reduced.

Description

technical field [0001] The invention belongs to the technical field of brake driving and braking, and in particular relates to a variable braking force device of a high-sensitivity brake. Background technique [0002] A brake is a device that has the functions of slowing down, stopping or maintaining a stopped state of moving parts (or moving machinery), and is a mechanical part that stops or slows down the moving parts in the machine. For the brake of the hoist, its main function is: when the hoist is not working, use the brake to brake the reel, and at the same time, perform safety braking when the hoist has an emergency accident. [0003] The hoist usually uses a disc brake for braking. When the hoist is started, the hydraulic station outputs pressure oil to open the brake, and the hoist starts to work. When the hydraulic oil is injected into the oil cylinder, the multiple disc springs are pushed by the piston. In the compressed state, when working and braking, the hydra...
