Or the support means 5 is part of the frame structure of the mobile device. In the embodiment, the supporting device 5 is C-shaped, and the upper end and the lower end of the central column 3 are respectively rotatably connected with the C-shaped supporting device 5 through bearings. In this embodiment, the rotating mechanism 4 is a motor and transmission gear assembly, and the central column 3 can be fixedly connected with a gear at a terminal in the transmission gear assembly. The rotating mechanism 4 drives the central column 3 to rotate on the supporting device 5, and the rotation center line is O.

The left end of the arm support 1 is rotatably connected with the upper part of the central column 3, and the connecting position is a point D. The right end of the arm support 1 is rotatably connected with one end, namely the left end, adjacent to the operation platform 2, and the connecting position is a point A. In this embodiment, the work platform 2 is composed of a protection frame and a bottom connection base, and the right end of the arm support 1 is connected with the left end of the connection base.

The fixed end of the pitching oil cylinder 7 is rotatably connected with the lower part of the central column 3, and the connecting position is an F point. The telescopic end of the pitching oil cylinder 7 is rotatably connected with the arm support 1, and the connection position is a point B. The connecting position B point is positioned between the connecting position D point of the arm support 1 and the central column 3 and the connecting position A point of the arm support 1 and the operation platform 2.

The telescopic end of the follow-up oil cylinder 8 is rotatably connected with the central column 3, the connecting position is N points, and the connecting position N point is located between the connecting position D point of the central column 3 and the arm support 1 and the connecting position F point of the central column 3 and the pitching oil cylinder 7.

The fixed end of the follow-up oil cylinder 8 is rotatably connected with the arm support 1, the connecting position is M point, and the connecting position M point is located between a connecting position D point of the arm support 1 and the central column 3 and a connecting position B point of the pitching oil cylinder 7 and the arm support 1.

The fixed end of the leveling cylinder 9 is rotatably connected with the other end of the arm support 1, the connection position is a point C, and the point C at the connection position is located between a point B at the connection position of the pitching cylinder 7 and the arm support 1 and a point connection position of the arm support 1 and the operation platform 2A. The telescopic end of the leveling oil cylinder 9 is rotatably connected with the operation platform 2, and the connection position is a T point. In this embodiment, the rotatable connection between the two components is implemented by a hinge, but may be implemented by other rotatable manners.

In the implementation, the servo oil cylinder 8 and the leveling oil cylinder 9 are connected in series in an inverted manner, so that the leveling oil cylinder 9 contracts while the servo oil cylinder 8 extends; and when the follow-up oil cylinder 8 contracts, the leveling oil cylinder 9 extends. The servo oil cylinder 8 and the leveling oil cylinder 9 adopt oil cylinders with the same type, so that the overall length L of the servo oil cylinder 8 is ensured_MN+ integral degree L of leveling cylinder 9_CTC is a constant value. Because the length of the fixed end of the follow-up oil cylinder 8 and the length of the fixed end of the leveling oil cylinder 9 are fixed, namely the sum of the extending length of the telescopic end of the follow-up oil cylinder 8 and the extending length of the telescopic end of the leveling oil cylinder 9 is also a fixed value.

The working principle of the automatic leveling system of the working platform is as follows:

the pitching cylinder 7 is in the shortest state, the boom 1 is at the largest angle under the horizontal line, at this time, the work platform 2 is at the lowest position, the length of the follow-up cylinder 8 is shortest, and the length of the leveling cylinder 9 is longest, as shown in fig. 3.

The pitching oil cylinder 7 extends out at a low speed, the arm support 1 gradually rises, and the length L of the follow-up oil cylinder 8_MNPassively and continuously extending along with the raising of the arm support, and adjusting the length L of the oil cylinder 9_CTAnd shortens as the length of the slave cylinder 8 increases, as shown in fig. 4. And the length elongation of the follow-up oil cylinder 8 is consistent with the length shortening of the leveling oil cylinder 9.

The pitching oil cylinder 7 reaches the longest state, the arm support 1 is positioned at the largest angle on the horizontal line, the operation platform 2 is positioned at the highest position, the follow-up oil cylinder 8 is longest in length, and the leveling oil cylinder 9 is shortest in length. As shown in fig. 5.

The action process is a working platform lifting process, otherwise, the action process is a working platform descending process.

It should be noted that the work platform is not absolutely level in the whole process, the level deviation can be controlled within the range of not influencing the normal operation of workers in the work platform at all, and the work platform is automatically leveled in the whole lifting process. Of course, the point location is preliminarily selected through a drawing method according to a mechanical drawing (as shown in figure 2); the point can be continuously optimized, and the optimization target is the accumulated change of the platform under the full-range inclination angle state. According to engineering requirements, when an optimization target reaches an allowable range, the optimization is stopped, then each point is close to and rounded, and then the accumulated change of the inclination angle of the platform under the actual condition is verified. If further optimization is needed, after a sufficient optimization target is achieved, a plurality of hinge points are eccentrically designed, and more excellent effect is pursued by eccentric fine adjustment. After optimization, the horizontal angle of the working platform is controlled within a tiny range of-1.06 degrees to +0.07 degrees in the whole pitching process of the automatic leveling system of the working platform.
