[0032] Please refer to Figs. 1 to 3 , an automatic escalator skirt board protection switch test tool is provided, comprising: a base assembly 10, a top rod assembly 20 and a power assembly 30.

[0033] The top rod assembly 20 is provided with a pressing part 21 for pressing the skirt board 41, and the top rod assembly 20 is movably arranged on the base assembly 10;

[0034] The power assembly 30 is arranged on the base assembly 10 and is drivingly connected with the top rod assembly 20, and the top rod assembly 20 is configured to move towards the test direction relative to the base assembly 10 under the driving of the power assembly 30.

[0035] When testing, the base is placed on the escalator 40, the power assembly 30 drives the top rod assembly 20 to move towards the testing direction, so that the pressing part 21 of the top rod assembly 20 abuts against the skirt plate 41, the pressing part 21 simulates the extrusion of the foreign matter to the skirt plate 41, and the pressing part 21 extrudes the skirt plate 41 to make the skirt plate 41 deform to test whether the safety switch of the skirt plate 41 works.

[0036] The specific structure of the power assembly 30 can be selected according to actual needs, for example, in some optional embodiments, the power assembly 30 comprises a telescopic module 31 and a reset elastic member 32, the telescopic module 31 is drivingly connected with the top rod assembly 20 to drive the top rod assembly 20 to move along the testing direction relative to the base, and the telescopic module 31 extends to drive the top rod assembly 20 to move along the testing direction to perform the test.

In this embodiment, the telescopic module 31 adopts a manual hydraulic pump, which is arranged on the base and has an output end connected with the top rod assembly 20.

[0038] The reset elastic member 32 is connected with the base assembly 10 and the top rod assembly 20 respectively, and when the top rod assembly 20 moves towards the testing direction relative to the base assembly 10, the top rod assembly 20 drives the reset elastic member 32 to elastically deform. After the test is completed and the telescopic module 31 is retracted, the elastic force of the reset elastic member 32 drives the top rod assembly 20 to move along the reverse direction of the testing direction, so as to realize the automatic reset of the top rod assembly 20.

[0039] In addition, it should be noted that the power assembly 30 can also adopt an electric cylinder, a pneumatic cylinder, a hydraulic cylinder and the like, and the automatic reset of the electric cylinder, the pneumatic cylinder or the hydraulic cylinder can eliminate the design of the reset elastic member 32.

[0040] In some optional embodiments, the base assembly 10 is provided with a guide 11 extending along the testing direction, and the top rod assembly 20 is slidingly matched with the guide 11, so as to improve the stability of the movement of the top rod assembly 20.
