Mechanical arm failure protecting device

Abstract

The invention relates to a mechanical arm failure protecting device which solves the problems that the prior mechanical arm power failure or overloading protection way is simple and has low reliability. The mechanical arm failure protecting device of the invention comprises a main control circuit and a failure mode control circuit, wherein the main control circuit is formed by connecting a first relay, a second relay and a band-type brake in series; the first relay is connected with an operation control signal of a mechanical arm; the second relay is connected with a failure mode control circuit; and the band-type brake is connected with a joint motor shaft of the mechanical arm. The invention has simple structure, small volume, high action reliability for different power failure types anduniversality, is easy to realize in electricity and structure, thoroughly solves the problem of power failure protection of a rotor and can be universally used for various mechanical arms of the rotors.

AI Technical Summary

Problems solved by technology

In the mechanical arm driven by the motor, when the driver fails or the output is interrupted due to other reasons, the inertia may cause the mechanical arm to lose control and drop rapidly, resulting in accidents

The current technology has little research on the power-off or overload protection of the manipulator, and most of the solutions are too simple or expensive to be practical.
