By setting the dust removal device 6, the pulley body 3 is first fixed on the adjusting rod 2, so that the adjusting rod 2 drives the pulley body The body 3 moves up and down to fit with the friction force. At this time, the transmission mechanism inside the body 1 is started by the controller 5, so that the transmission mechanism inside the body 1 drives the friction wheel 4 to rotate, so that the friction wheel 4 fits with the surface of the pulley body 3 and drives the pulley body 3 to rotate, and the durability test of the pulley body 3 is completed. At this time, the pump 65 is started, so that the pump 65 provides suction to the concave cover 66 through the pipeline 64, so that the concave cover 66 absorbs the powder or debris generated by the friction between the friction wheel 4 and the pulley body 3, so that the absorbed powder or debris enters the rectangular frame 61 through the concave cover 66 and the pipeline 64 and falls into the collection box 62 for collection and storage, thereby completing the dust removal of the body 1, reducing the powder and debris generated during the test of the friction wheel 4 and the pulley body 3 scattered on the body 1, causing the surface of the body 1 to be dirty and affect the normal operation of the personnel, and improving the cleanliness of the body 1 and the convenience of dust removal.
[0027] Specifically, Figure 2 and Figure 3As shown, a pull rod 63 is fixedly connected to one side of the collection box 62, and the surface of the pull rod 63 is T-shaped. By setting the pull rod 63, personnel can easily move the collection box 62 by manually moving the pull rod 63, thereby improving the convenience and stability of manually moving the collection box 62. A support column 67 is fixedly connected to one side of the concave cover 66, and the surface of the support column 67 is in contact with the surface of the body 1.

By setting the anti-accidental touch device 7, the protective plate 73 is first manually moved to make the protective plate 73 drive the round rod 72 to move up and down along the inside of the circular hole block 71. When the round rod 72 moves to a position completely inserted into the inside of the circular hole block 71, the protective plate 73 completely covers the buttons on the controller 5 and intercepts external objects, thereby reducing the situation where personnel accidentally touch the buttons on the controller 5 during the test, causing the running program of the body 1 to change and affect the test data.
[0029] Specifically, Figure 4 As shown, an auxiliary plate 74 is fixedly connected to one side of the protective plate 73, and the surface of the auxiliary plate 74 is rectangular.

The end of the round rod 72 away from the protective plate 73 is fixedly connected to a circular plate 75, and the surface of the circular plate 75 is larger than the inner wall of the circular hole block 71. By setting the circular plate 75, the circular plate 75 can intercept the round rod 72 during the movement, thereby reducing the possibility that the round rod 72 will escape from the inside of the circular hole block 71 during the movement.
[0030] The working principle of the utility model is:
[0031] S1. First, fix the pulley body 3 on the adjusting rod 2, so that the adjusting rod 2 drives the pulley body 3 to move up and down and fit with the friction force. At this time, start the transmission mechanism inside the body 1 through the controller 5, so that the transmission mechanism inside the body 1 drives the friction wheel 4 to rotate, so that the friction wheel 4 fits with the surface of the pulley body 3 and drives the pulley body 3 to rotate, and completes the durability test of the pulley body 3. At this time, start the pump 65, so that the pump 65 provides suction to the concave cover 66 through the pipeline 64, so that the concave cover 66 absorbs the powder or debris generated by the friction between the friction wheel 4 and the pulley body 3, so that the absorbed powder or debris enters the rectangular frame 61 through the concave cover 66 and the pipeline 64 and falls into the collection box 62 for collection and storage, completing the dust removal operation of the body 1.
[0032] S2. First, manually move the auxiliary plate 74 so that the auxiliary plate 74 drives the protective plate 73 to move, and the protective plate 73 drives the round rod 72 to move up and down along the inside of the circular hole block 71. When the round rod 72 moves to a position completely inserted into the inside of the circular hole block 71, the protective plate 73 completely covers the buttons on the controller 5 and intercepts external objects, thereby preventing the buttons of the controller 5 from being accidentally touched.
