Embodiment 1

[0036] The invention provides a test device for an elevator overspeed governor, such as Figure 1-3 As shown, the elevator speed governor test device includes a speed governor tester host, an electrical switch test device and a detection module 5 .

[0037] Wherein, the overspeed governor test host 2 includes a driving pressure wheel, a host housing, a motor controller, a driving motor and a power supply installed in the host housing. The driving pressure roller is installed on the top of the main engine shell, and contacts with the speed governor wheel 6 of the speed governor to be tested.

[0038] The main engine casing is fixedly installed on the metal bracket 1 of the speed governor to be tested, so as to support the stable contact between the driving pressure wheel and the speed governor wheel 6 .

[0039] The motor controller is electrically connected with the motor, and is used to control the operation of the drive motor, and then drive the speed governor wheel 6 of th...

Embodiment 2

[0064] Based on Embodiment 1, the present invention also provides another embodiment, a kind of elevator overspeed governor testing system, such as image 3 As shown, it includes an elevator speed governor test device provided in Embodiment 1, a mobile device terminal and a cloud server.

[0065] Among them, the elevator speed limiter test device is connected with the mobile device end, by sending the detected data to the mobile device end, the mobile device end can Parameter information, the instantaneous action signal of the electrical switch of the speed limiter when it is disconnected can obtain the measurement results of the speed limiter, and generate a test report, and then upload the test report to the cloud server for storage.

Embodiment 3

[0067] Based on the first embodiment, the present invention also provides another embodiment, such as Figure 4 As shown, a test method for an elevator speed limiter is applied to a test system for an elevator speed limiter provided in Embodiment 2, and the test method includes the following steps:

[0068] Step S1, drive the speed governor to be tested to rotate through the elevator speed governor testing device.

[0069] Step S2, obtain the speed of the speed governor wheel of the speed governor to be tested in real time through the elevator speed governor testing device during the rotation process. The velocity includes acceleration, angular velocity, and the like.

[0070] Wherein, the speed of the speed governor wheel of the speed governor to be tested during rotation can be obtained through a detection module installed on the speed governor wheel, or can be obtained through a rotary encoder connected to the motor of the speed governor to be tested.

[0071] Step S3, wh...

Abstract

The invention discloses an elevator speed limiter testing device. The elevator speed limiter testing device comprises a speed limiter testing host, a vibration sensor and a detection module; the speedlimiter testing host comprises a driving pinch roller, a host shell, a motor controller, a driving motor and a power supply, the motor controller, the driving motor and the power supply are installedin the host shell; the host shell of the speed limiter testing host is fixedly mounted on a metal bracket on a speed limiter to be tested; the motor controller controls the work of the driving motor,then drives a speed limiter wheel of the speed limiter to be tested to rotate through the driving pinch roller; and the detection module and the vibration sensor respectively acquire the rotation speed of the speed limiter wheel and the action signal when an electric switch of the speed limiter to be tested is switched off, and send the rotation speed and the action signal to a mobile device terminal, so that the mobile device terminal realizes that testing the speed limiter to be tested is carried out. The elevator speed limiter testing device solves the problems that in the prior art, whentesting the elevator speed limiter is carried out, dismounting the shell or an insulating layer of the speed limiter needs to be carried out, and consequently the operation is inconvenient. The invention further provides an elevator speed limiter testing system and method.

Description

technical field [0001] The invention relates to the test of an elevator overspeed governor, in particular to a testing device, system and method for an elevator overspeed governor. Background technique [0002] Elevator safety gear and upward overspeed protection device are important safety devices to ensure that the elevator does not exceed the safe operating speed, prevent the expansion of accidents and reduce the risk of accidents. When the elevator runs out of control due to overspeed, control failure, insufficient pulling stress, brake failure, insufficient braking force, and suspension device breakage, etc., the elevator speed limiter will act and link the elevator safety gear to quickly stop the elevator car on the guide rail, and make the elevator Stay stationary to avoid personal injury or equipment damage. As the elevator safety gear and the key drive component of the upward overspeed protection device, the speed governor of the elevator is the key to ensure the r...
