Problems solved by technology

However, when actually controlling the band brake, manual drive and drive cylinder drive usually belong to two braking methods. In an emergency, it may take a certain amount of time to switch between the two braking methods. The control of the brake band is not very emergency.

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 It is a structural schematic diagram of a linked band brake provided by an embodiment of the present invention. Such as figure 1 As shown, the linkage type band brake includes a brake band 1 and a drive structure 2, the brake band 1 is used to wrap on the brake wheel 3, one end of the brake band 1 is fixed, and the other end of the brake band 1 is transmitted to the drive structure 2 connect.

[0027] The driving structure 2 includes a cylinder housing 201 , a spring seat 202 , a driving rod 203 , a hand lever 204 , a spring 205 and a control member 206 .

[0028] The spring seat 202 is coaxially arranged in the oil cylinder housing 201, the spring seat 202 is sealed and connected with the oil cylinder housing 201, the driving...

Abstract

The invention discloses a linkage type band brake, which belongs to the field of mechanical equipment. In actual use, hydraulic oil can be fed into the cylinder housing on one side of the spring seat, the hydraulic oil pushes the spring seat to drive the drive rod to move along the axial direction of the drive rod, and the other end of the drive rod pushes the control plate along the axial direction of the drive rod Displacement occurs, and the control board rotates with the fixed position of the control part as the fulcrum to drive the brake band hinged with the control part to release or close the brake wheel, and finally recover under the action of the spring located on the side of the cylinder housing and the spring seat in situ. The rotation of the manual rod can also be controlled to control the rotation of the drive rod. The seal connection between the drive rod and the cylinder housing will cause the control part threaded with the drive rod to shift in the axial direction of the drive rod, and then realize the braking The wheel is released or closed. The control is all acting on the drive rod, and there is no need to spend time switching between manual and hydraulic control methods, and the emergency response is better.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a linkage type band brake. Background technique [0002] Band brakes are common devices used to brake brake wheels. The conventional structure of a band brake includes a brake band for wrapping a brake wheel and an actuating cylinder. The brake belt is wrapped on the brake wheel, one end of the brake belt is fixed, the other end of the brake belt is connected with the piston rod of the driving cylinder, and the piston rod of the driving cylinder is stretched to control the closing and releasing of the brake belt to the brake wheel . [0003] For safety reasons, the band brake controlled by the drive cylinder generally also adds a manual drive at the other end of the brake band to control the closing and releasing of the brake band to the brake wheel. However, when actually controlling the band brake, manual drive and drive cylinder drive usually belong to two braking method...
