Abstract
The utility model discloses a speed measurement device of an elevator speed limiter. The speed measurement device comprises a drive motor, a driving wheel disposed on an output shaft of the drive motor, a mounting plate located on the lateral portion of the output shaft of the drive motor and with one end movably connected on a shell of the drive motor, a pressing mechanism fixedly connected on the shell of the drive motor and pressing the top end of the mounting plate, a rotating rod connected with the mounting plate in a rotating mode and provided with a speed measurement sensor, a driven wheel located on one end of the lateral portion of the driving wheel and an external control display device. The speed measurement sensor is electrically connected with the control display device. The speed measurement device is simple in structure and convenient to carry. The drive motor is adopted to drive a wheel disc of the speed limiter to rotate, and the driven wheel rotates following the wheel disc of the speed limiter. Therefore, the rotation speed of the driven wheel is the rotation speed of the wheel disc of the speed limiter, and the measured rotation speed of the driven wheel is the rotation speed of the wheel disc of the speed limiter. Measurement results are accurate so that safety indexes of an elevator are guaranteed.
Description
Technical field
The utility model relates to the elevator safety detection field, specifically a kind of speed measuring device of elevator governor.
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 mode that tests the speed of existing elevator governor mainly comprises two kinds, a kind of is to drive velocity limiter wheel disc spins by manpower, then adopt speed gage to measure, another kind is to drive velocity limiter wheel disc spins by drive motor, then detects by the tachogenerator that is installed on the drive motor output shaft.First kind of way drives and detects due to artificial, and its safety is low, easily causes in operation artificial damage; The second way is because tachogenerator is arranged on the drive motor output shaft, what its essence was measured is the rotating speed of drive motor, although the velocity limiter wheel disc is to drive rotation by drive motor, the rotating speed of drive motor is the rotating speed of velocity limiter wheel disc in theory, but when skidding occurring between the two, the rotating speed of velocity limiter wheel disc is just different from the rotating speed of drive motor, thus the rotating speed of drive motor is just inaccurate as the rotating speed of velocity limiter wheel disc, affect the accuracy that tests the speed of speed measuring device.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of speed measuring device of elevator governor, and it is installed on tachogenerator on flower wheel, has guaranteed the measurement accuracy of velocity limiter wheel disc rotating speed.
The technical solution of the utility model is:

The top of described drive motor housing is provided with handle.
Advantage of the present utility model:
(1), the utility model is simple in structure, easy to operate, adopts drive motor to drive velocity limiter wheel disc spins, guaranteed the safety of testing the speed;
(2), the utility model adopts drive motor to drive velocity limiter wheel disc spins, flower wheel is taken turns disc spins with velocity limiter, so the rotating speed of flower wheel is the rotating speed of velocity limiter wheel disc, so the rotating speed of the flower wheel of measuring is the rotating speed of velocity limiter wheel disc, its result of a measurement is accurate, thereby has guaranteed the safety index of elevator;
(3), the utility model is simple in structure, easy to carry, is the integrated design, and directly flower wheel device and control display device is installed on the drive motor housing, when carrying, the handle that only need hold drive motor can arbitrarily move this device.
