By rotating the mounting plate 21, the wheels 19 are driven to rotate 360 ​​degrees, thereby driving the gantry to move and change direction, thereby improving the flexibility of the gantry. The inside of the shell 14 is fixedly connected to a bracket 15, and the bottom of the bracket 15 contacts the ground, and the wheels 19 can be retracted under the base 5 to support the base 5.

A spring 18 is fixedly connected to the exterior of the housing 14. A pedal 13 is rotatably connected to the exterior of the housing 14. Pressing down on the pedal 13 drives the wheels 19 downward, bringing them into contact with the ground, facilitating the movement of the gantry on the road. The gantry's movement direction can be changed by the action of the mounting plate 21. Simultaneously, the bracket 15 rises upward, away from the ground. Pushing the pedal 13 upward drives the wheels 19 upward under the action of the spring 18. A rotating shaft 20 is fixedly connected to the interior of the wheel 19, which is rotatably connected to the interior of the housing 14. The bottom of the crossbeam 1 is fixedly connected to the support frame 12. The outer side of the support frame 12 is fixedly connected to the exterior of the column 2, increasing the stability of the gantry during operation.

Under the action of the mounting plate 21, the moving direction of the gantry can be changed. At the same time, the bracket 15 rises upward away from the ground. Push the pedal 13 upward to drive the wheel 19 to rise upward under the action of the spring 18, so that the bottom of the bracket 15 contacts the ground. The wheel 19 can be retracted under the base 5 to support the base 5. The structure is simple, easy to use, and increases the stability of the gantry during operation.
