Abstract

The invention discloses a normally-closed hydraulic brake. The normally-closed hydraulic brake comprises a base fixing plate, two guide poles, a first brake pad carrier, a second brake pad carrier, a first brake pad, a second brake pad, a reset spring and a brake cylinder component. The two guide poles are vertically mounted on the base fixing plate. The first brake pad carrier sleeves the two guide poles. The first brake pad is mounted on the first brake pad carrier. The brake cylinder component comprises a hydraulic cylinder, a piston rod and a plurality of disc springs. A cover plate is arranged at the top of the hydraulic cylinder. The disc springs are compressed in the hydraulic cylinder by the cover plate. A joint communicated with the bottom of an inner cavity of the hydraulic cylinder is arranged on the lateral side of the hydraulic cylinder. A top plate is arranged at the upper end of the piston rod and is connected with the second brake pad carrier through a push rod. The second brake pad is mounted on the face, opposite to the first brake pad carrier, of the second brake pad carrier. The upper end of the reset spring is connected with a guide pole connecting plate, and the lower end of the reset spring is connected with the brake cylinder component. The normally-closed hydraulic brake is simple and compact in structure, convenient to operate and easy to control and produce.

Description

technical field [0001] The invention relates to a brake, in particular to a normally closed hydraulic brake. Background technique [0002] Brakes are the most important safety equipment for the operation and control of winches and hoists. The performance of the brakes directly determines whether the winches and hoists can work safely and normally. In order to ensure the safety and reliability of winches and hoisters in various stages of transportation, installation, and operation, the working state of existing winches and hoister brakes is usually closed. [0003] At present, the brakes used by winches and hoists are mainly to arrange a pair of hydraulic cylinders on both sides of the brake discs of winches and hoists respectively, and use the elastic restoring force of springs or disc springs to brake or brake the winches and hoists. Release the brake operation. [0004] Since the hydraulic cylinders in a pair of brakes on both sides of the brake disc of the winch and ...
