[0032] Specifically, when turning, the steering motor 14 drives the small gear 12 to rotate around the large gear 7, and the turntable 17 connected to the steering motor 14 rotates accordingly.

[0033] The lower surface of the turntable 17 is provided with two axle brackets 20 which are symmetrically arranged front and back. The axle brackets 20 are rotatably connected with a wheel axle 18, and a driving wheel 19 is installed on the wheel axle 18. There are two driving wheels 19, and the two driving wheels 19 are symmetrically arranged about the turntable 17. The axle bracket 20 is provided with a reducer 6 and a travel motor 8. The output shaft of the travel motor 8 is connected to the input shaft of the reducer 6 through a coupling, and the power output end of the reducer 6 is connected to the wheel axle 18. The outer side surface of the axle bracket 20 is provided with a support frame 16, and a lateral support wheel 15 is installed on the support frame 16.

[0034] Specifically, when the equipment is moving, the travel motor 8 drives the wheel axle 18 to rotate, and the wheel axle 18 drives the driving wheel 19 to rotate.

[0044] Specifically, the annular positioning plate 41 fixes the strip-shaped steel ball bracket 42 together, and butter grease can be applied around the strip-shaped steel ball bracket 42 .

[0045] When in use: install no less than one electrically controlled walking mechanism to the lower end of the outer side of the mechanical equipment, and ensure that after the driving wheel 19 is lifted, the mechanical equipment can stand stably on the ground. When moving the position of the mechanical equipment, the hydraulic cylinder 11 extends to push out the driving wheel 19 to lift the mechanical equipment as a whole, and then start the travel motor 8. The travel motor 8 drives the driving wheel 19 to rotate through the reducer 6 to realize the movement of the equipment.
