[0047] In use, the detection wheel 11 is brought into contact with the upper surface of the handrail on one side of the escalator. The first suction cup 108 is attached to the inner wall of the skirt panel directly below the handrail. The drive motor 106 is started, causing the two connecting parts 104 to move closer together along the drive screw 105, which in turn causes the two clamping plates 102 to move closer together, so that the clamping wheels 109 on the two clamping plates 102 simultaneously contact both sides of the handrail, thereby making the detection wheel 11 stably placed on the upper surface of the handrail. The second detection wheel 21 is placed on the upper surface of one step, and the second suction cup 204 is attached to the inner wall of the skirt panel, making the second detection wheel 21 stably placed on the upper surface of the step. The escalator is started, and the handrail drives the detection wheel 11 to rotate. The escalator steps drive the second detection wheel 21 to rotate. The inspector obtains the running speed data of the handrail through the handrail speed detection unit 12 and the running speed data of the steps through the step speed detection unit 22. This allows the inspector to compare the speed of the handrail and the speed of the steps.

[0048] Furthermore, the handrail speed detection unit 12 transmits the handrail's running speed data to the central processing unit 31, and the step speed detection unit 22 transmits the step's speed data to the central processing unit 31. The step speed data and the handrail's running speed data can be displayed on the display module 32 for easy viewing.

[0049] Meanwhile, during the test, it is necessary to select the speed at which the handrail detection structure 1 detects the left or right handrail belt. Therefore, the suction end of the first suction cup 108 needs to be rotated. After the second turntable 42 drives the first suction cup 108 to rotate to a suitable angle, the screw is simultaneously inserted into the first locking hole 411 and the second locking hole 421, so that the first turntable 41 and the second turntable 42 are relatively fixed, thereby completing the fixation of the first suction cup 108.

[0050] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
