[0042] Working principle:

[0043] The first drive motor 111 drives the first drive wheel to rotate, and the first drive wheel moves along the ground rail 160. The first driven wheel also moves along the ground rail 160. That is, the first drive wheel and the first driven wheel support and drive the moving lower beam 100 to move. The first guide wheel 112 and the second guide wheel 121 play a guiding role, assist the movement of the moving lower beam 100, and enhance the stability of the moving lower beam 100.

[0044] The second drive motor 410 drives the first gear to rotate. Through the meshing of the first gear and the first rack 220, the first slide plate 400 can be moved up and down along the first slide rail 210, thereby driving the lifting beam 600 to rise and fall. Simultaneously, during the lifting of the lifting beam 600, the first steel cable 360 ​​drives the first counterweight frame 330 to rise and fall, ensuring the stability of both sides of the lifting column 200 and the counterweight column 300, thus ensuring the stability of the subsequent gantry structure. The cooperation of the first limiting plate 310 and the first limiting groove 350 restricts the lifting of the first counterweight frame 330, preventing it from swaying. The first protective cover 370 protects the lower end of the counterweight column 300, preventing workers from being crushed by the first counterweight frame 330, making the process safer and more reliable.

[0045] Furthermore, the third drive motor 510 drives the second gear 520 to rotate. Through the meshing of the second gear 520 and the second rack 620, the second slide plate 500 can be moved along the second slide rail 610. Processing equipment for wind turbine blades (such as grinding and fabric laying equipment) can be installed on the second slide plate 500, allowing for the processing of wind turbine blades. The first electrical box 540 can supply power to the wind turbine blade processing equipment. Moreover, the processing equipment can be installed upright or upside down, thus enabling the processing of both the upper and lower surfaces of the wind turbine blades, thereby improving the processing efficiency.

[0046] It is worth mentioning that the technical features such as processing equipment involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the utility model point of this utility model patent.
