[0020] The front-end electric platform vehicle 1 and the rear-end electric platform vehicle 2 both include a frame 7, a lead-acid battery 8, a controller 9, a differential drive wheel 10 and a follower wheel 11. The lead-acid battery 8 is installed in the frame 7, the controller 9 is embedded in the outer wall of the frame 7, and the controller 9 is electrically connected to the lead-acid battery 8. The differential drive wheel 10 is installed at one end of the bottom of the frame 7, and the differential drive wheel 10 is electrically connected to the controller 9, and the follower wheel 11 is installed at the other end of the bottom of the frame 7.

[0021] Specifically, the front-end electric platform vehicle 1 and the rear-end electric platform vehicle 2 are of the same size, and the turntable 4 is flush with the platform 5 .

[0022] In this embodiment, the lead-acid battery 8 provides energy for the electric platform vehicle, the motor of the differential drive wheel 10 converts electrical energy into mechanical energy to move the vehicle, and the turntable 4 and the platform 5 are load-bearing structures for placing the large substation module 6.

[0023] Specifically, a battery compartment 12 is provided inside the vehicle frame 7 , and the lead-acid battery 8 is located in the battery compartment 12 .

[0024] In this embodiment, the battery compartment 12 provides a safe environment for storing the battery pack to prevent the battery from being damaged by the external environment.

[0025] Specifically, the battery compartment 12 is provided with partitions 13 on both sides, and heat dissipation holes 14 are provided between the partitions 13 and the adjacent sides of the battery compartment 12 .

[0026] In this embodiment, the compartment 13 provides a safe environment for storing electrical components such as the power management module 16 and the cooling fan 15 .

[0027] Specifically, a cooling fan 15 is installed in the partition 13 , and the cooling fan 15 is electrically connected to the controller 9 .

[0028] In this embodiment, the main function of the cooling fan 15 is to help the battery pack dissipate heat, prevent the battery pack from being damaged due to overheating, and extend the service life of the battery pack.

Specifically, the differential drive uses two independently driven motors or electric machines to drive two drive wheels. When the rotation speeds of the two motors are the same, the differential will cause the two drive wheels to rotate at the same speed, allowing the vehicle to move in a straight line. When the rotation speeds of the two motors are different, the differential will cause the two drive wheels to rotate at different speeds, thereby realizing the turning of the vehicle. For example, assuming a left turn, the motor on the left will be set to rotate slower, and the motor on the right will be set to rotate faster. In this way, the differential will cause the left drive wheel to rotate slower and the right drive wheel to rotate faster through the cooperation of the planetary gears and the chuck, so that the vehicle can turn left.

One of them is a disc free-rotating structure, and the other is a platform fixed structure. During transportation, the two vehicles drill into the lower part of the module and are arranged front and back. One is with steering and the other is fixed for use. The lead-acid battery 8 provides energy for the electric platform vehicle, and the motor of the differential drive wheel 10 converts electrical energy into mechanical energy to make the vehicle move, and the controller 9 is responsible for controlling the energy transfer and output between the battery and the motor, which solves the problem of large turning radius of tractors for domestic transportation of large modules, increases the flexibility of production layout of large pre-installed substations in workshops, does not require special tooling, and can be operated by two people, thereby improving the efficiency of safe production.
