[0010] Furthermore, the driving unit comprises a hydraulic cylinder, a cylinder end of the hydraulic cylinder is hinged to the base, and a telescopic rod end of the hydraulic cylinder is hinged to the flip and leveling platform.

[0011] Beneficial effects: In this solution, the driving unit adopts a hydraulic cylinder, which is more stable and can bear a larger weight. In this solution, the telescopic rod and cylinder body of the hydraulic cylinder are respectively hinged on the flip leveling platform and the base, so that the flip leveling platform can be driven to achieve the purpose of flipping through the telescopic movement of the telescopic rod of the hydraulic cylinder.

[0012] Furthermore, a cylinder body connecting seat is installed at the position where the base is connected to the cylinder body of the hydraulic cylinder, and a telescopic rod connecting seat is installed at the position where the flip and leveling platform is connected to the telescopic rod of the hydraulic cylinder.

[0039] A lift 3 is installed on the flipping and leveling platform 2, and a lifting platform 301 is provided on the lift 3. In this embodiment, two groups of lifts 3 are provided, and the two lifts 3 are symmetrically arranged on the left and right parts of the flipping and leveling platform 2 respectively. Manual operations are performed by standing on the lifting platform 301 of the lift 3, and the lift 3 can drive the lifting platform 301 to perform lifting movements.

[0040] In this embodiment, the flip and leveling platform 2 is a rectangular frame structure, which is convenient for achieving lightweight. A support column 201 is connected to the bottom of the free end of the flip and leveling platform 2. The support column 201 is used to support the flip and leveling platform 2, and when the support column 201 is against the base 1, the flip and leveling platform 2 and the base 1 are parallel to each other. In this embodiment, there are multiple support columns 201, and the multiple support columns 201 are spaced apart along the length direction of the flip and leveling platform 2.

[0041] A driving unit is provided between the flipping and leveling platform 2 and the base 1 , and the driving unit can drive the flipping and leveling platform 2 to flip along the base 1 to adjust the angle between the flipping and leveling platform 2 and the base 1 .

[0042] In this embodiment, the driving unit includes a hydraulic cylinder 4, the cylinder end of the hydraulic cylinder 4 is hinged to the base 1, and the telescopic rod end of the hydraulic cylinder 4 is hinged to the flip leveling platform 2. Specifically: Figure 3 and Figure 4 As shown, a cylinder body connecting seat 402 is installed at the position where the base 1 is connected to the cylinder body of the hydraulic cylinder 4, a telescopic rod connecting seat 401 is installed at the position where the flip leveling platform 2 is connected to the telescopic rod of the hydraulic cylinder 4, and the cylinder body and the telescopic rod of the hydraulic cylinder 4 are hinged to the cylinder body connecting seat 402 and the telescopic rod connecting seat 401 respectively.

[0043] In the present embodiment, there are two hinge units between the flipping and leveling platform 2 and the base 1, and the two hinge units are symmetrically arranged with each other, so that there are two hinge points between the flipping and leveling platform 2 and the base 1. In the present embodiment, two drive units are provided, and the two drive units are symmetrically arranged on both sides of the flipping and leveling platform. In the present embodiment, there is a hydraulic cylinder 4 mentioned above at the position of each hinge unit, that is, two symmetrically distributed hydraulic cylinders 4 are arranged in the present embodiment, and the two hydraulic cylinders 4 can respectively support the left and right parts of the flipping and leveling platform 2, so that the flipping and leveling platform 2 can be stable, and the equipment installed on the flipping and leveling platform 2 is also more stable.

[0044] In this embodiment, the hinge unit includes a rotating rod 6 and two fixed seats 5. The two fixed seats 5 are welded to the base 1 and connected with screws or bolts.

After arriving at the designated position, personnel get on the vehicle to operate the platform vehicle, and the construction personnel operate the lifting device 3 to perform maintenance work on the lifting platform 301. Since the slope of the flow channel is a curved surface, its slope based on the bottom plane is different at different positions. Therefore, by starting the hydraulic cylinder 4, the telescopic rod of the hydraulic cylinder 4 is extended to flip the flip leveling platform 2, and the angle between the flip leveling platform 2 and the base 1 is adjusted to level the lift 3 at different positions of the flow channel, so that the construction personnel can maintain a horizontal state for maintenance work.

[0047] Example 2

[0048] The difference between this embodiment and embodiment 1 is that when the maintenance platform vehicle is used on a slope, the flip-over leveling platform 2 (i.e., the load-bearing platform) must first be leveled. The load-bearing platform is supported by two hydraulic cylinders 4. In order to achieve automatic leveling, the electrical control system and the hydraulic system must be used under computer control to form an organic whole to operate in a coordinated, efficient, and accurate manner.

[0049] In this embodiment, horizontal sensors are installed on the flip and leveling platform 2 to detect the front and back and left and right inclinations of the flip and leveling platform 2 respectively. The rise of each hydraulic cylinder 4 can cause their changes. The inclination angle of the horizontal sensor is automatically read through the PLC control system, the inclination is determined, and leveling is automatically performed.
