[0025] Specifically, since the first drive gear 603 and the second drive gear 605 are provided, it can be ensured that there is always a gear engaged with the first arc-shaped rack 601.

[0029] Example 2, continue to refer to Figure 1-Figure 4 In an embodiment of the present invention, the movable positioning wheel mechanism 2 includes a movable deflection shaft 201 rotatably connected to the fixed mounting plate 1, and one end of the movable deflection shaft 201 away from the fixed mounting plate 1 is fixedly connected to the positioning wheel seat 202, and the inner side of the positioning wheel seat 202 is rotatably connected to the positioning wheel 203, and the positioning wheel seat 202 is threadedly connected to the feed thread rod 204, and the end of the feed thread rod 204 is provided with a rubber clip 205.

[0030] Specifically, when the positioning wheel 203 moves to the specified position, the rubber clip 205 is rotated, and the rotation of the rubber clip 205 drives the feed threaded rod 204 to rotate, so that the rubber clip 205 is against the positioning wheel 203 to prevent the positioning wheel 203 from continuing to rotate.

[0031] During the implementation of the present invention, the equipment is first moved to the position of the gantry crane working component that needs to be processed by moving the positioning wheel mechanism 2. At this time, by adjusting the rotating arc plate mechanism 5 on the first displacement mounting assembly 3 and the second displacement mounting assembly 4, that is, opening the two-way driving mechanism 6, the state of the rotating arc plate mechanism 5 is adjusted, and the state of the deflection plate mechanism 7 is adjusted at the same time, so that the gantry crane working component is placed between the first displacement mounting assembly 3 and the second displacement mounting assembly 4, avoiding the existence of interference.
