The bearing assembly 2 is characterized by having two horizontally arranged bearing beams 201, with a support beam 202 positioned above each bearing beam 201. The bearing beams 201 and support beams 202 are fixedly connected at both ends by connecting arms 203. Several tie rods a204 are inclinedly arranged between the connecting arms 203 to fix the bearing beams 201 and support beams 202.

It should be noted that a rubber limiting block is provided at the upper end of the support beam 202 to restrict the web in the horizontal direction.

[0022] The drive assembly 3 includes several mounting plates 301 fixedly connected to the lower surface of the load-bearing beam 201. Steering seats 302 are fixedly connected to the lower ends of two rows of mounting plates 301 near the front end of the load-bearing beam 201 and one row of mounting plates 301 near the rear end of the load-bearing beam 201. The upper end of a rotating shaft 303 is rotatably connected within the steering seat 302. A fixed disk 304 is fixedly connected to the lower end of the rotating shaft 303. A steering wheel 305 is rotatably connected to the fixed disk 304. The lower surface of the steering wheel 305 is connected to the wheel frame 306. The upper end is fixedly connected, and the lower end of the wheel frame 306 is rotatably connected to the drive wheel 307. The drive wheel 307 is connected to the gearbox 308 fixedly connected to the side of the wheel frame 306 via the transmission shaft. The upper end of the gearbox 308 is connected to the drive motor 309. The side wall of the steering wheel 305 is fixedly connected to the driven gear ring 310. The driven gear ring 310 is meshed with the drive gear 311 on one side. The drive gear 311 is fixedly connected to the output shaft of the steering motor 312 installed on the side of the steering seat 302.

[0023] The drive assembly 3 also includes a fixed base 313 fixedly connected to the lower end of the remaining mounting plate 301. The upper end of the steering shaft 314 is rotatably connected inside the fixed base 313. The lower end of the steering shaft 314 is fixedly connected to a wheel frame a315. The lower end of the wheel frame a315 is rotatably connected to a driven wheel 316.

[0024] The load-bearing component 2 also includes a tie rod b206 that is fixedly connected between the connecting beam 205 and the support beam 202.

[0025] The bottom end of the battery pack 1 is connected to the supporting beam 201.

[0026] An angle sensor is installed on the shaft 303, and a wheel speed sensor is installed on the drive wheel 307.

[0027] Among them, the battery 1 is electrically connected to the electronic control device, and the drive motor 309, steering motor 312, angle sensor and wheel speed sensor are all electrically connected to the electronic control device. The electronic control device has a built-in wireless transmission module, which can be wirelessly connected to the remote control device.

[0028] Among them, the surfaces of the support beam 202, the connecting beam 205, and the reinforcing rod a207 are provided with a rubber layer.

[0029] Working principle: First, the web of the wind turbine blade to be transported is placed horizontally on the top of the bearing assembly 2. That is, the web is placed on the rubber layer on the upper surface of the support beam 202, connecting beam 205, and reinforcing rod a207. Then, a command is sent to the electronic control device via a remote control device. After receiving the command from the remote control device, the built-in wireless receiving module of the electronic control device controls the drive motor 309 to rotate. The rotating drive motor 309 drives the transmission shaft to rotate through the gearbox 308, which in turn drives the drive wheel 307 to rotate. The driven wheel 316 will also rotate, thereby causing the bearing assembly 2 to move the web. When turning is required, a command can be sent to the control device via the remote control device, so that the control device controls the two rows of blades near the front end of the bearing beam 201. The output shaft of the steering motor 312 drives the drive gear 311 to rotate, which in turn drives the gear ring 310 meshing with it to rotate. The gear ring 310 then synchronously drives the steering wheel 305 to rotate on the fixed plate 304. The rotating steering wheel 304 can synchronously drive the wheel carrier 306 and the drive wheel 307 to rotate at a certain angle. The driven wheel 316 and the wheel carrier a315 will adjust their angles according to the steering of the drive wheel 307. Under the control of the electronic control device, a row of steering motors 312 near the rear end of the load-bearing beam 201 will drive the gear ring 310 to rotate through the drive gear 307 according to the Ackermann steering geometry, which in turn drives the steering wheel 305 and the wheel carrier 306 to rotate, thereby enabling the drive wheel 307 to perform angle compensation to complete the steering.
