[0038] The walking trolley 23 comprises a walking motor 231, a chassis 232, front wheels 233, rear wheels 234, a push-pull electromagnet 235, a driving bevel gear 236, and a driven bevel gear 237. The chassis 232 is connected to one side of the main frame 211. The upper side of the main frame 211 is connected with a handrail 24. The front wheels 233 and the rear wheels 234 are sequentially rotatably connected to the lower side of the chassis 232. The other end surface of the front wheels 233 is connected with a connecting shaft 2310. The driven bevel gear 237 is connected to one end of the connecting shaft 2310. The driving bevel gear 236 is meshingly connected to the driven bevel gear 237. The end surface of the driving bevel gear 236 is connected with a spline sleeve 238 and a spline shaft 239. The walking motor 231 is installed on the upper side of the chassis 232. The output shaft of the walking motor 231 is connected with the push-pull electromagnet 235 after penetrating through the chassis 232. The lower side of the push-pull electromagnet 235 is connected with the spline shaft 239. The spline sleeve 238 is cooperatively connected to the outer peripheral surface of the spline shaft 239.

[0039] In the embodiment, the structure of the automatic leveling base 3 can refer to the automatic leveling base disclosed in Chinese Patent CN219809627U. The front wheels 233 and the rear wheels 234 of the walking trolley 23 are H-shaped and clamped on the track 1 to walk. The walking motor 231 is a servo motor. The push-pull electromagnet 235 is sleeved on the outside of the output shaft of the servo motor. The lower end of the push-pull electromagnet 235 is connected with the top surface of a thrust bearing. The bottom surface of the thrust bearing penetrates through the output shaft of the servo motor and is connected with the spline sleeve 238. The spline sleeve 238 is installed with a travel switch at the initial position of movement. The travel switch is connected with a green indicator light or a buzzer alarm device.

[0040] The power is transmitted to the spline gear through the walking motor 231. The spline gear is connected with the spline sleeve 238. Normally, the power is disconnected. When the walking motor 231 is powered, the push-pull electromagnet 235 is synchronously powered. At this time, the movable iron core and the push rod of the push-pull electromagnet 235 move to generate a pushing force to drive the spline sleeve 238 to move downward so that the inner ring gear thereof is engaged with the spline shaft 239. At this time, the torque can be transmitted to the driving bevel gear 236. The power is further transmitted to the connecting shaft 2310 through the driving bevel gear 236, thereby driving the front wheels 233 to rotate. The thrust bearing between the push-pull electromagnet 235 and the spline sleeve 238 can make the spline sleeve 238 rotate with the lower end surface of the thrust bearing, so as to ensure that the spline sleeve 238 can freely rotate during the downward movement to avoid being stuck. The upper end surface of the thrust bearing is connected and fixed with the push-pull electromagnet 235, so as to ensure that the push-pull electromagnet 235 can only move upward and downward while not rotating with the shaft or the spline sleeve 238. When the walking motor 231 is powered off, the push-pull electromagnet 235 is powered off. At this time, the spline sleeve 238 is automatically reset under the action of the spring force. When it is reset to the initial position, it touches the travel switch. At this time, the green indicator light is on, indicating that the walking motor 231 is completely disconnected.

[0041] The push-pull electromagnet 235 is fixed on the bottom frame 232, the middle part of the connecting shaft 2310 is connected with the front wheel 233 through a key, and the end of the connecting shaft 2310 is provided with the encoder 41. Since the walking motor 231 can detect the input rotation angle, the wheel rotation speed cannot be detected when the power is disconnected. When the vehicle needs to be pushed, the encoder 41 is installed on the wheel connecting shaft 2310 to detect the wheel rotation angle to calculate the running distance. In work, the difference between the two rotation angles can also be used to feedback the combination of parts and the gear gap.
