Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] figure 1 It is a structural schematic diagram of a band brake device provided by an embodiment of the present invention, such as figure 1 As shown, the band brake device includes a brake lever 20 and a brake band 30. The brake band 30 includes a support band 31 and a brake pad 32 arranged on one side of the support band 31. One end of the brake lever 20 is hinged to one end of the support band 31. , the rotation axis of the brake lever 20 is perpendicular to the length direction of the brake band 30 and parallel to the surface 31a of the brake band 30, the other end of the support band 31 is connected with a connecting seat 60, and the connecting seat 60 is provided with a pin shaft 61, and the pin shaft The axis of 61 is paral...

Abstract

The invention discloses a belt-type brake device and belongs to the field of brake devices. The belt-type brake device comprises a brake rod and a brake belt. The brake belt comprises a supporting belt and a brake pad arranged on one side face of the supporting belt; one end of the brake rod is hinged to one end of the supporting belt, the rotating axis of the brake rod is perpendicular to the brake belt in the length direction and parallel to the surface of the brake belt, the other end of the supporting belt is connected with a connection seat, and the connection seat is provided with a pin shaft; and the brake rod is provided with a plurality of concave clamping grooves in a spaced manner in the direction away from the rotating axis of the brake rod, and the pin shaft is arranged on the brake rod in a supported manner through one of the concave clamping grooves. After the brake pad is worn and thinned, the pin shaft is clamped into the corresponding concave clamping groove closer to the rotating axis of the brake rod by adjusting the position of the pin shaft so that a gap between the brake pad and a brake wheel can be reduced, and the problem that braking time is longer and longer due to the fact that the gap between the friction pad and the brake wheel is larger and larger due to wear of the friction pad is solved.

Description

technical field [0001] The invention relates to the field of brake devices, in particular to a band brake device. Background technique [0002] The band brake device is a very common brake device, which is often used on various winches. [0003] The belt brake device mainly includes a brake lever and a brake band. The brake band is arranged around the rim of the brake wheel. The brake lever is respectively hinged with both ends of the brake band. When the brake lever is pushed and pulled to rotate the brake lever, the brake band is tightened. Thereby the brake wheel is held tightly to brake the brake wheel. [0004] Since the brake pads on the brake pads will be worn continuously during the braking process, the brake pads will become thinner and thinner, and the gap between the brake pads and the brake wheels will increase, so that the brake pads will not affect the brake pads when braking. The friction of the wheels is reduced, making it take longer to complete the brakin...
