[0056] ​The method is to transport the head cover 1 to be assembled to the assembly position with the vehicle body by the ground moving mechanism, and adjust the position of the head cover 1 on the ground moving mechanism in X, Y and Z directions, so that the relative position of the head cover 1 and the vehicle body meets the docking requirements, and finally the assembly between the head cover 1 and the vehicle body is completed. This method changes the existing technology of using hoisting to transport the head cover and the vehicle body for assembly, optimizes the installation process of the head cover 1 and the vehicle body, is convenient to operate, and greatly improves the operation efficiency of the head cover assembly. At the same time, it is also more convenient for the assembly between the head cover and the vehicle body with complex head shape, pipe and equipment mounting rack at the bottom, which is not easy to hoist and carry, and can be applied to the assembly of head cover 1 and vehicle body with any head shape, and has stronger universality. At the same time, since the ground moving mechanism is used to transport the head cover 1 to be assembled to the assembly position with the vehicle body, the safety factor is higher, and compared with the traditional hoisting and carrying method, the operation process is safer and more reliable.

[0057] Further, the ground moving mechanism includes a ground moving vehicle 2, a first supporting device 3 and a second supporting device 4, and the step S1 further includes the following steps:

In this way, the head cover 1 and the supporting device are transported twice during assembly, which can reduce the weight and height of each transportation of the ground transportation equipment, so that the transportation is more stable and reliable. At the same time, the X and Y direction adjusting structure and the Z direction adjusting structure are installed on the first supporting device 3 and the second supporting device 4 respectively, the position of the head cover 1 in X and Y directions is adjusted by adjusting the position of the second supporting device 4 in X and Y directions, which is also conducive to simplifying the overall structure of the supporting device, reducing the cost of the device, and also conducive to reducing the difficulty of adjustment, making the adjustment more convenient and fast, and greatly improving the operation efficiency.

[0071] The first support platform 31 is preferably in a frame structure, which is composed of an upper platform 311, a lower platform 312 and several vertical beams 313 supported in the middle. The lower platform 312 is fixedly connected with the ground moving vehicle 2, and the second support device 4 is placed on the upper platform 311. Further preferably, the upper platform 311 and the lower platform 312 are both rectangular metal plates with a certain thickness, and four groups of the first adjusting mechanisms 5 are respectively installed on the four sides of the upper platform 311 and the lower platform 312.
