The speed detecting sensor and the driving motor are respectively and electrically connected with the control display device. According to the elevator speed governor safety detecting device, the driving motor drives a speed governor wheel disc to rotate, and meanwhile the speed detecting sensor connected with the driven wheel detects rotating speed of the speed governor wheel disc timely, then, the rotating speed is transmitted to the control display device for displaying, and meanwhile the control display device controls rotating speed of the motor according to the speed, and therefore safety performance when the driving motor drives the speed governor wheel disc to rotate is guaranteed, and when the detected rotating speed of the speed governor wheel disc is close to mechanical speed, the control display device controls the driving motor to rotate stably, and therefore accuracy of the detected mechanical speed during braking is guaranteed.
Description
Technical field
The utility model relates to the elevator safety detection field, specifically a kind of elevator governor safety detection device.
Background technology
Velocity limiter is important safety parts of elevator, it at any time Monitoring and Controlling the speed of car, when the supervelocity situation occurring, namely 115% of rated speed of lift the time, can in time send signal, then produce mechanical action and cut off feed circuit, make the towing machine braking.The safety tongs action that is arranged on car bottom if elevator still can't be braked is forced stop with car.At present, a mechanical speed all can be indicated by velocity limiter manufacturer on product before velocity limiter dispatches from the factory, the rotating speed of velocity limiter wheel disc when this mechanical speed is the braking of velocity limiter control safety tongs, if and this speed is inaccurate, especially when this speed is too high, will affect braking constantly, thereby cause the safety problem of elevator operation.
The speed measuring device of existing elevator governor mainly logical drive motor drives velocity limiter wheel disc spins, and then the rotating speed when measuring the velocity limiter wheel disc and being braked.Because the speed of drive motor can be more and more faster, the speed of velocity limiter wheel disc thereupon is also more and more faster, stop until being braked when reaching the velocity limiter mechanical speed, but its acceleration/accel is corresponding control not, because speed is always acceleration/accel, so the acceleration/accel of the velocity limiter wheel disc before being braked can be very high, cause the safety of drive motor driving velocity limiter wheel disc spins in the process of testing the speed, and affect the accuracy of the mechanical speed of measuring when braking.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of elevator governor safety detection device, thereby it adopts the control display device to control the velocity of rotation of drive motor according to the signal data of feedback, guarantees velocity limiter the test the speed safety in process and the accuracy that tests the speed.
The technical solution of the utility model is:
The elevator governor safety detection device, include drive motor, be arranged at drive wheel on the drive motor output shaft, be arranged at the drive wheel sidepiece with the flower wheel of tachogenerator and external control display device, described tachogenerator and control display device are electrically connected to, described control display device is electrically connected to the driver train of drive motor by the D/A change-over circuit, and the driver train of drive motor is used for driving the drive motor output shaft rotation.
Described control display device comprises microcontroller and the read-out that is connected with microcontroller respectively and press key input device, and described tachogenerator, D/A change-over circuit all are connected with microcontroller.
On the housing of described drive motor and the sidepiece that is positioned at the drive motor output shaft be connected with adapter plate, on the housing of drive motor, captive joint is useful on the hold-down mechanism of pushing down the adapter plate top, be rotatably connected to the dwang with tachogenerator on adapter plate, described tachogenerator and flower wheel are arranged at respectively the two ends of dwang.
The top of the housing of described drive motor is provided with handle.
Advantage of the present utility model:
When drive motor of the present utility model drives velocity limiter wheel disc spins, the tachogenerator that is connected with flower wheel detects the rotating speed of velocity limiter wheel disc in real time, then being transferred to the control display device shows, the control display device is controlled the rotating speed of drive motor according to this speed simultaneously, guarantees the safety performance when drive motor drives velocity limiter wheel disc spins; And when the rotating speed of the velocity limiter wheel disc that detects leveled off to mechanical speed, the control display device was controlled the stable rotation of drive motor, the accuracy of the mechanical speed of having measured when having guaranteed braking.
