The adjusting bolt 2 passes through the vertical through hole 101 on the adjusting base 1 and is tightened by the double nuts. The first nut 3 and the second nut 4 are located on both sides of the adjusting base 1. By turning the nuts, the adjusting bolt 2 is driven to move in the vertical direction, thereby completing the adjustment of the unit height. At least one horizontal connecting component 9 is disposed on the adjusting base 1 for connecting adjacent unit transport sections 8 together after the unit height adjustment is completed. The present invention has a compact overall structure and good rigidity, integrating adjustment and connection functions into one unit, making operation convenient and quick; it adopts a bolt and nut transmission mechanism to achieve linear stepless adjustment, the adjustment process is intuitive and highly accurate, far superior to the traditional shim leveling method, greatly improving installation quality and efficiency.

[0026] Specifically, it also includes a first shim 5 and a second shim 6 for anti-loosening purposes. The first shim 5 and the second shim 6 are fitted onto the adjusting bolt 2, and the two shims are respectively located between the first nut 3, the second nut 4, and the adjusting base 1. The use of shims enhances the anti-loosening capability, avoids potential safety hazards such as slippage and detachment, and enhances the overall stability of the unit.

[0027] Specifically, the adjusting base 1 includes a transition plate and a boss, which are integral structures and perpendicular to each other, with an L-shaped or T-shaped form. The transition plate is connected to both ends of the side wall of the unit base 7 by fasteners. Specifically, the adjusting base is made of high-strength material, has good rigidity, and enhances the overall stability of the unit.

[0028] Specifically, the fasteners are pins or bolts, and the adapter plate of the adjusting base 1 has a positioning hole 103. After the pin or screw passes through the positioning hole 103, the adjusting base 1 is fastened to the unit base 7.

[0029] In one specific embodiment, one adjusting base 1 is installed at each of the four corners of the front and back sides of each unit base 7, and the horizontal connecting assembly 9 adopts a connecting bolt assembly, when any two adjacent unit transport sections 8 are placed side by side, the connecting bolt is locked and fixed by penetrating the horizontal hole 102 of the two adjacent adjusting bases 1 and then passing through a third nut, and a third gasket is arranged between the third nut and the adjusting base 1.

[0030] A leveling method for field installation of air conditioning unit transport sections, which is completed by using the height-adjustable unit connecting structure as described above, comprises the following steps: The plurality of unit transport sections 8 are respectively positioned at the installation site; The adjusting base 1, the adjusting bolt 2, the double nut and the double gasket are installed on the unit base 7 of each transport section; The nut in each connecting member structure is screwed to drive the adjusting bolt 2 to rise or fall, so that each unit transport section 8 is in the same horizontal plane; After the height adjustment is completed, the horizontal connecting assembly 9 is used to connect the adjacent unit transport sections 8 into one through the horizontal hole 102 of the adjusting base 1.

[0031] Specifically, the height adjustment process is to adjust each unit transport section 8 in turn until all the unit transport sections 8 are in the same horizontal plane.

[0032] The leveling and connecting steps are combined in the same component in the present application, which reduces the installation process and adjustment time, is particularly suitable for rapid field assembly of large modular equipment, facilitates the optimization of the installation process and improves the construction efficiency. At the same time, it is convenient for later maintenance and re-adjustment. If the levelness changes due to foundation settlement or equipment displacement, the connecting structure can be directly used for re-adjustment without disassembling the main structure, which is convenient for maintenance and has a long service life.
