Speed limiter detection device

Abstract

The invention relates to a speed limiter detection device which comprises a shell, a driving module, a display module and a processing module. Containing space is defined by the shell. The driving module comprises a driving motor, a driving wheel and a speed sensing unit. The drive motor is provided with a rotating shaft. The driving wheel is arranged on the rotating shaft in a sleeving manner andabuts against a pulley of a speed limiter, and the driving wheel is driven by the rotating shaft to enable the pulley to rotate synchronously. The speed sensing unit and the rotating shaft are coaxially arranged on the driving motor, and a rotating speed sensing signal corresponding to the rotating speed of the rotating shaft can be generated according to the rotating state of the rotating shaft.The display module is arranged in the shell. The processing module is electrically connected with the driving motor, the speed sensing unit and the display module, and the processing module can generate speed information according to the rotating speed sensing signal returned by the speed sensing unit and enables a screen of the display module to display the speed information. In the manner, theoperation complexity can be effectively reduced, and the correctness of a detection result can be improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device of a speed governor. Background technique [0002] In high-rise buildings, elevators have become indispensable equipment. Carrying people or goods through elevators can save people a lot of time and effort. General elevator equipment is usually equipped with a number of safety devices such as speed limiters, calipers, buffer columns, etc., to ensure the safety of passengers. Among the above safety devices, the speed limiter will control the elevator car to stop moving when the moving speed of the elevator car descends or rises to a certain extent, so as to avoid various safety problems, which is the first safety protection mechanism of the elevator. A guarantee. [0003] refer to figure 1 , a kind of overspeed governor 8 of today comprises a support 81, a pulley 82, an electromagnetic brake 87 and a mechanical brake 88, and a steel cable 89 connected with the elevator c...

Problems solved by technology

[0005] However, in the above inspection process, since the motor 91 and the detector 92 are two independently operating devices, the inspectors not only need to carry and carry the motor 91 and the detector 92 separately, but also have to install them in stages, which is inconvenient to use.

Moreover, in the installation and testing operations, the testing personnel must first start the motor 91, and then the pulley 82 is driven by the motor 91, and then the hand-held testing instrument 92 is leaned against the pulley 82 for detection. In this way, the testing personnel must monitor the motor 91 While observing the rotation speed of the pulley 82 measured by the tester 92, whether it conforms to the speed at which the electromagnetic brake 87 and the mechanical brake 88 should be actuated, and the hand of the tester must keep the tester 92 against the pulley 82 , not only the operation is extremely inconvenient, but also the detection results from human observation are prone to detection errors
