[0039] The utility model proposes an elevator distance sensor tester for use in a sensor testing process. The utility model does not limit the type of elevator sensors, but the workbench 1, the detection cabinet 2, the simulated up-and-down stairs drive module 3 and the simulated installation module 4 are particularly suitable for testing the sensitivity and accuracy of the sensor.

[0040] In general, the elevator distance sensor detector proposed by the utility model mainly includes: a workbench 1, a detection cabinet 2, a simulated up and down stairs driving module 3 and a simulated installation module 4, among which, you can refer to Figure 1 , which shows the arrangement relationship of the workbench 1, the detection cabinet 2, the simulated up-and-downstairs driving module 3 and the simulated installation module 4.

[0042] The detection principle of the elevator distance sensor tester proposed by the utility model is to drive the slide cylinder 33 to simulate the installation module 4 to move up and down to simulate the elevator going up and down floors. By setting a certain distance of the sensor as one layer, it is judged whether the sensor will light up and send a stop signal when it moves up or down to a specific distance to judge whether the sensor is accurate. In order to prevent artificial misjudgment, half of the length of the moving track of the slide cylinder 33 can be taken as a layer parameter, and the length of the elevator steel belt 45 can also be selected as this parameter to simulate the elevator going up and down on the first and second floors. If the sensor error is large and the light can only be turned on once or not even once in a round, it needs to be adjusted.

[0043] The bottom left and right sides of the workbench 1 are provided with raised legs 11, and a detection cabinet 2 is placed on the top of the workbench 1. The detection cabinet 2 is composed of four side walls to form a hollow cavity 21, and the front of the detection cabinet 2 is open to facilitate the installation of the sensor.

For the elevator steel belt 45 contacted by the locking block 46, a close bolt 48 is arranged between every two locking knobs 47. The bottom of the close bolt 48 is passed through the cross plate 41 to prevent the elevator steel belt 45 from falling off during testing due to a gap at one end of the contact between the cross plate 41 and the pressure plate 42 due to the large parallelism tolerance. The tooling table 49 is designed to be connected to the bottom of the No. 2 slide 35 by bolts. Sensor placement boxes 410 are arranged at equal intervals on the side of the tooling table 49 close to the front opening of the detection cabinet 2.
