[0037] Next, the hydraulic cylinder 4 drives the inner frame 3 to move upward together with the first standard section 1 until a sufficient height is left for the entry of the second standard section 1. The forklift then delivers the second standard section 1 into the bottom outer frame 22 from the standard section entrance 23. The hydraulic cylinder 4 drives the first standard section 1 downward to support it on the standard section 1 below.

The number of standard sections is set according to the second height H2.

[0039] 3. Use at least two flipping devices to lift one side of the support grid 10 so that the entire support grid 10 flips and tilts. The flipping devices are evenly spaced at the bottom of the support grid 10 as much as possible to ensure that the support grid 10 is evenly stressed.

[0040] like Fig. 9 , Fig.10 As shown, the structure of each flipping device includes: a hydraulic axis vehicle 7, a first tower 71 and a second tower 72 are respectively arranged at the two end positions of the hydraulic axis vehicle 7, a flip beam 8 is arranged on the top of the first tower 71 and the second tower 72, one end of the flip beam 8 is hinged to the top of the first tower 71, and the other end of the flip beam 8 is supported on the top of the second tower 72. One end of the flip beam 8 hinged to the first tower 71 is the hinged end of the flip beam, and the other end is the free end of the flip beam.

Afterwards, the drive rod of the oil cylinder 74 on each hydraulic axis vehicle 7 extends outward, driving the free end of the flip beam to flip upward relative to the hinge end of the flip beam, so that the support grid 10 flips until it is tilted in place. The hydraulic axis vehicle 7 has the advantages of easy walking, can assist in precise support positioning, and has strong bearing capacity.

[0042] It can be seen from the above that the lifting and flipping method of the support grid of the solar photovoltaic assembly described in the present application has the following advantages: First, it is lifted by filling the next standard section at the bottom of the previous standard section 1. The method is simple but very clever, stable and reliable. The lifting drive mechanism only needs to lift the previous standard section up to the height filled by the next standard energy saving each time, which effectively reduces the travel requirements of the lifting drive mechanism, thereby reducing the lifting and flipping cost; in addition, each time, only the previous standard section needs to be lifted up to the height filled by the next standard energy saving, so that the connection work between the upper and lower adjacent standard sections only needs to be carried out at this height each time, which greatly reduces the manual operation height, thereby reducing the difficulty of lifting and flipping of the support grid, greatly improving the safety of the lifting work, and effectively reducing the number of construction personnel, thereby further reducing the lifting and flipping cost. Second, a first tower 71 and a second tower 72 supporting a flip beam 8 are set on the hydraulic axis vehicle 7, and a cylinder 74 is used to drive one side of the flip beam 8 to flip to realize the driving of flipping the support grid 10. Such operation is highly safe, easy to control, and requires a small number of construction personnel. 3.

Anti-skid pads are provided on the support beams at the contact position with each ball node to increase the friction, which can further effectively prevent the support grid 10 from sliding downward during the flipping process. 4. The provision of the bottom support frame 2 with the inner frame 3 facilitates the installation of the lifting drive and the filling and jacking of the standard section. 5. The entire jacking and flipping action has high safety and good stability, which greatly improves the installation efficiency of the support grid of the solar photovoltaic module.
