Description

Microswitch triggering reset mechanism for brake

[ background of the invention ]

The power-off brake is a mechanical device for braking and releasing a brake disc by using a spring and a power supply as power sources, and performs braking under the condition of power failure, so the power-off brake is called as the power-off brake. The structure of the magnetic release device comprises a magnetic yoke, an armature, a spring, a coil, a friction disc, a friction plate, a release handle, a microswitch and the like. The working principle of the power-off brake is as follows: the magnet yoke and a coil arranged on the magnet yoke form an electromagnet, when the coil is not electrified, the spring presses the armature iron on the friction plate, and friction resistance is formed on the friction plate, so that the friction plate is braked, and equipment connected to the friction plate is braked; when the coil is electrified, the magnetic force generated by the magnetic yoke is opposite to the thrust generated by the spring, and the armature is attracted to one side of the magnetic yoke by the electromagnetic force larger than the thrust of the spring to separate the armature from the friction plate, so that a gap is generated between the armature and the friction plate, the friction resistance acting on the friction plate disappears, and the brake is released.

When the armature is attracted by the coil during actual work, the trigger mechanism triggers the microswitch so that the microswitch generates an electric signal and transmits the electric signal to the alarm controller, and the alarm controller judges whether to alarm or not according to the power-on and power-off conditions of the coil and the electric signal of the microswitch; when the coil is in a power-on state and the microswitch is not triggered, the situation that the armature blocks moving or the coil is broken is shown, the alarm controller gives an alarm to prompt that the fault occurs, when the coil is in a power-off state, if the microswitch is in a trigger state, the situation that the armature is not tightly abutted against the friction plate is shown, the brake is in a failure state, and the alarm controller gives an alarm to prompt that the fault occurs. The flexibility and reliability of the existing trigger mechanisms are yet to be improved.
