Embodiment 1）

[0035] In this embodiment, the braking of the reel of the hoist hoist of the water conservancy gate is taken as an example for illustration. The hoist hoist includes a frame 6, a bearing seat, a bearing, a drum shaft, a drum and a brake disc 5. Bearing seat has 2 points and is fixed on the frame 6 front and back, and bearing is fixedly installed on the reel shaft, and is also installed in the corresponding bearing seat, and reel is fixed on the reel shaft. The reel includes a cylindrical winding portion. The brake disc 5 can be a circular plate specially set and fixed at one end of the winding portion of the reel. The brake disc 5 is arranged coaxially with the rotating shaft of the reel. The brake disc 5 is welded or fixed on the reel by bolts. One end of the coil. It can also be the original rope retaining plate that doubles as a brake disc; the outer diameter of the brake disc 5 is greater than the diameter of the winding portion of the reel. The brake disc 5 includes tw...

Abstract

The invention discloses a self-locking outer edge brake which comprises a braking force bearing support, a connecting rod, a braking arm and a jacking mechanism. One end of the connecting rod is rotatably connected with the braking force bearing support, and the other end of the connecting rod is rotatably connected with a mounting end of the braking arm. The jacking mechanism is located below the braking arm. The end face contour of a braking end of the braking arm is adaptive to a side face of a round disc to be braked. A friction plate is fixedly arranged on the end face of the braking end and is tightly attached to and fully covered on the end face of the braking end. When the braking arm is in a braking position, the friction plate is attached to the side face of the braking disc. The self-locking outer edge brake carries out braking to the cylindrical side face of the round disc to be braked like a side face of the braking disc of a coiling block and achieves the purposes of enabling the coiling block to brake, and stopping a heavy object to move. The self-locking outer edge brake is simple in structure, small in occupied space, fast in braking response, strong in braking performance, safe and reliable.

Description

technical field [0001] The invention relates to the field of brakes, in particular to a self-locking outer edge brake. Background technique [0002] Winch lifting equipment includes winches and hoist hoists for water conservancy gates. The reel of hoisting lifting equipment is usually braked by braking the motor shaft. The braking of the motor shaft is divided into external brakes and built-in brakes. The external brake is to install a disc brake on the motor shaft between the motor and the reducer. The motor generally uses an asynchronous motor; the built-in brake is to brake through the brake disc in the motor. motor. The lifting equipment must ensure sufficient safety, and the existing motor shaft braking always has insurmountable hidden dangers. In the event of a sudden accident such as brake failure or power failure, or due to the heavy load on the motor shaft, the shaft will be broken, the brake will not have any effect, and the reel will have a major safety acciden...
