Intelligent brake and control method thereof

Abstract

The invention discloses an intelligent brake and a control method thereof. The intelligent brake comprises a shell and a motor; the motor is in transmission connection with a spring base through a transmission mechanism; the spring base is arranged in the shell; a brake spring, fixedly connected with the spring base through one end, is arranged in the shell; the other end of the brake spring is fixedly connected with the shell; and the spring base is in transmission connection with a brake shoe through a brake arm mechanism. The intelligent brake further comprises a controller, and an encodercoaxially connected with the motor; the controller comprises a driving module and a CPU module; the CPU module is electrically connected with the motor through the driving module; and the encoder is electrically connected with the CPU module. The intelligent brake can precisely measure the wear of a brake shoe gasket, automatically adjusts a brake shoe gap, automatically measures and adjusts the magnitude of braking force, automatically adjusts the braking delay time, can automatically detect the heat fading condition of the brake shoe gasket, reduces the use and maintenance workload, improvesthe working efficiency, and prevents accidents.

Description

technical field [0001] The invention belongs to the field of brakes, in particular to an intelligent brake and a control method thereof. Background technique [0002] Brakes are widely used in ports, mines, logistics, transportation, power plants and other fields. They are widely used in hoisting mechanisms, hoisting mechanisms, mine hoisting, walking mechanisms, belt transportation and other mechanisms in the above fields. With the increasing automation and intelligence of equipment and the stricter safety supervision, it is particularly important to automatically adjust the brake mechanism and automatically detect the braking parameters. [0003] Current brakes have the following disadvantages: [0004] 1. Existing brakes use limit switches to detect the wear limit of the brake shoe liner, which cannot accurately measure the wear amount of the brake shoe liner. [0005] 2. The opening clearance of the brake shoe of the existing brake is usually realized by manually adjus...

AI Technical Summary

Problems solved by technology

[0004] 1. Existing brakes use limit switches to detect the wear limit of the brake shoe liner, which cannot accurately measure the wear amount of the brake shoe liner

[0005] 2. The opening gap of the brake shoe of the existing brake is usually realized by manually adjusting the mechanical structure, and the opening gap of the brake shoe cannot be adjusted accurately and automatically

[0006] 3. The braking force of existing brakes cannot be automatically measured

[0007] 4. The existing brake needs to manually adjust the compression of the brake spring to adjust the braking force, which cannot automatically adjust the braking force

[0008] 5. The existing brake can only adjust the braking time by manually adjusting the damping valve, which is troublesome to adjust and has poor accuracy and consistency, and cannot automatically adjust the delayed braking time

[0009] 6. The existing brakes cannot automatically detect and deal with the thermal degradation of the brake shoe lining
