Abstract

The invention discloses a belt brake device, and belongs to the technical field of brake braking. In the device, a first brake belt is hinged to one end of a second brake belt; a rotating rod is movably arranged on the outer wall of the first brake belt; one end of the rotating rod and the first brake belt are connected through a spring module and an extension oil cylinder arranged side by side; the middle part of the rotating rod is hinged to a frame; and the other end of the rotating rod is hinged to the other end of the second brake belt through a connecting module. As the spring module and the extension oil cylinder are arranged between the rotating rod and the first brake belt side by side, when the spring module loses effect, an extension end of the extension oil cylinder can shrink and elongate, and the acting force of the extension end is used for replacing the acting force of the spring module to guarantee the brake braking function of a hub.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a band brake device. Background technique [0002] The towing winch is used in three-purpose engineering ships to carry out towing platform operations and anchor handling operations in the ocean. The belt brake device is a key component of the towing winch, and its operation reliability directly determines the performance of the towing winch. [0003] In the prior art, the band brake device is usually a normally closed brake device, that is, a brake device that can realize the braking function without starting the hydraulic pump station under normal conditions. The traditional normally closed brake device uses a spring cylinder to achieve braking. The compression spring is installed in the cylinder barrel of the telescopic cylinder, and the compression spring outputs the initial spring force to act on the piston rod to realize the brake of the brake device. [0004] In the proces...
