Abstract
The utility model is aimed at providing a motor brake apparatus. The motor brake apparatus is characterized in that a brake elevating cylinder is installed in the housing a motor, that a brake friction plate is installed on the top of the brake elevating cylinder, that the brake elevating cylinder is externally connected with a cylinder pipe, that the cylinder pipe is connected with a gas source through a solenoid valve, that the solenoid valve is connected with a motor controller, and that the motor controller is connected with the motor and a power supply.
Description
Technical field
The utility model relates to a kind of motor brake device.
Background technology
Existing three-phase synchronous motor, the brakeless device, shut down after entirely cutting off the power supply by self.But in use, when the load of motor is Melt Pump, after the motor outage; due to the pressure of melt, the Melt Pump of usually can getting excited, the rotation slowly of Melt Pump drive motor rotor; cause the melt source and course to lose, cause raw material to run off, make troubles to maintenance pump shaft etc. simultaneously.
The utility model content
In order to overcome above-mentioned technical problem, the utility model aims to provide a kind of motor brake device, and concrete technical scheme is as follows:
A kind of motor brake device, it is characterized in that: comprise the braking lift cylinders be arranged in motor casing, brake strip is installed at braking lift cylinders top, braking lift cylinders external gas earthen pipe, cylinder tube is connected with source of the gas by electromagnetically operated valve, electromagnetically operated valve is connected with motor controller, and motor controller is connected with power supply with motor respectively.
Motor brake device of the present utility model, under normal operation, motor rotary shaft frictional disk and brake strip are not collided, at regular intervals, and electromagnetically operated valve must not be electric, motor can normally move, and when motor stops, the normally closed point of motor controller is connected, controlling electromagnetically operated valve obtains electric, source of the gas, makes on brake strip to move and joins with the motor rotary shaft frictional disk the inflation of braking lift cylinders by cylinder tube, makes motor brake.Through reality, use, good braking effect, fault is few.Can realize reducing material loss, purpose easy to maintenance.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-cylinder tube, 2-source of the gas, 3-motor rotary shaft frictional disk, 4-power supply, 5-braking lift cylinders, 6-brake strip, 7-motor, 8-motor casing, 9-motor controller, 10-electromagnetically operated valve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of motor brake device, it is characterized in that: comprise the braking lift cylinders 5 be arranged in motor casing 8, brake strip 6 is installed at braking lift cylinders 5 tops, braking lift cylinders 5 external gas earthen pipes 1, cylinder tube 1 is connected with source of the gas 2 by electromagnetically operated valve, electromagnetically operated valve 10 is connected with motor controller 9, and motor controller 9 is connected with power supply 4 with motor 7 respectively.
Under normal operation, motor rotary shaft frictional disk 3 is not collided with brake strip 6, at regular intervals, and electromagnetically operated valve 10 must not be electric, and motor 7 can normally move, when motor 7 stops, the normally closed point of motor controller 9 is connected, and control electromagnetically operated valve 10 obtains electric, and source of the gas 2 is by 1 pair of braking lift cylinders 5 inflation of cylinder tube, make on brake strip 6 to move and join with motor rotary shaft frictional disk 3, make motor 7 brakings.
Finally, it is also to be noted that, what more than enumerate is only specific embodiment of the utility model, and obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should think protection range of the present utility model.
