The upper surfaces of the lifting and filling parts are provided with multiple through grooves, and a communicating vessel is formed in the solution tank 231. The solution tank 231 is filled with a supporting liquid, and the supporting liquid is a high-density liquid.

The tethers 234 will make the flip step plate 22 and the support rods 233 movably connected, have a certain range of movement, and can also prevent the two from detaching;

[0050] When the tilt angle of the flip-type step mechanism 2 is changed by being pushed by the support mechanism 4, the supporting liquid in the solution tank 231 will be adjusted adaptively, so that the supporting liquid in the two lifting and filling parts of the solution tank 231 always maintains the same horizontal plane, and the two floats 232 and the two rows of support rods 233 are respectively located in the same horizontal plane, and the lower ends of the flip step plate 22 are respectively in contact with the two rows of support rods 233.

The two rows of clamps 263 are respectively fixed to the two moving rods 261, and each of the two sides of the rotating shaft 24 has two clamps 263 respectively. The two clamps 263 are respectively fixed to the two moving rods 261, and an arc groove adapted to the rotating shaft 24 is opened on the clamp 263. The outer surface of the rotating shaft 24 and the arc groove are both provided with evenly distributed triangular protrusions 264 to increase the friction between the clamp 263 and the rotating shaft 24.

[0052] After the inclination angle of the flip step mechanism 2 is adjusted to the corresponding angle, the multiple flip step plates 22 are also kept horizontal, and the telescopic ends of the two straight rod motors 262 can be extended, so that the two moving rods 261 run in opposite directions, and the corresponding two clamping blocks 263 will also clamp the rotating shaft 24 to prevent the rotating shaft 24 and the flip step plate 22 from flipping by themselves, thereby ensuring the stability of the flip step plate 22; conversely, when the flip step plate 22 needs to be loosened, the telescopic end of the straight rod motor 262 can be retracted, and the clamping block 263 will loosen the rotating shaft 24. Embodiment 2

[0053] This embodiment is further optimized on the basis of the first embodiment, and the same parts as the above technical solution will not be repeated here. Figure 2 As shown, in order to better realize the present invention, the following setting is particularly adopted: the support mechanism 4 in this embodiment includes a first slide rail slider structure 41, a base 42, a first hydraulic telescopic rod 43, a second hydraulic telescopic rod 44 and a support frame 45; the base 42 is slidably installed on the automobile chassis 1 through the first slide rail slider structure 41, and the sliding direction is along the length direction of the automobile chassis 1. The number of the first slide rail slider structures 41 is at least 2, the first hydraulic telescopic rod 43 is fixed to the automobile chassis 1, and the telescopic end of the first hydraulic telescopic rod 43 is fixedly connected to the base 42, the second hydraulic telescopic rod 44 is installed at the upper end of the base 42, the number of the second hydraulic telescopic rod 44 is at least 2, and the second hydraulic telescopic rod 44 is vertically arranged, the support frame 45 is fixed to the lower side of the head of the side frame 21, and the upper end of the second hydraulic telescopic rod 44 is rotatably connected to the support frame 45 through a rotating shaft;

[0054] When increasing the inclination angle of the flip-type step mechanism 2, the second hydraulic telescopic rod 44 can be moved toward the tail of the automobile chassis 1 by contracting the telescopic end of the first hydraulic telescopic rod 43, and the head of the flip-type step mechanism 2 can be pushed upward and flipped by extending the telescopic end of the second hydraulic telescopic rod 44. In this process, the operating speeds of the first hydraulic telescopic rod 43 and the second hydraulic telescopic rod 44 need to be accurately coordinated and controlled through a set program.

[0055] In this embodiment, the linkage mechanism 5 includes a vertical frame 51, a gear set 52, a flip frame 53, two sets of racks 57 and a second slide rail slider structure 54; the gear set 52 is rotatably mounted on the rotating shaft, the gear set 52 has two gears, the two gears are fixedly connected, and the size ratio of the two gears is set according to needs, the vertical frame 51 is fixed to the outer cylinder part of the second hydraulic telescopic rod 44, the outer cylinder part is the second hydraulic telescopic rod 44 will not be extended, or the vertical frame 51 is directly fixed to the automobile chassis 1 through the connecting frame, the flip frame The upper end of 53 is slidably connected with the bottom of the standing platform 3 and vertically flipped through the second slide rail slider structure 54, that is, the second slide rail slider structure 54 is installed at the bottom of the standing platform 3, a rotating rod is installed on the slider of the second slide rail slider structure 54, and the rotating rod is vertically flipped and connected with the flip frame 53, the lower end of the flip frame 53 is slidably connected to the support frame 45, and the vertical frame 51 and the flip frame 53 are both provided with a rack 57, and the racks 57 on the vertical frame 51 and the flip frame 53 are respectively meshed and connected with the two gears of the gear set 52;

[0056] The vertical frame 51 and the flip frame 53 are both slidably installed on the support frame 45 through the third slide rail slider structure 55, so that the inclination angles of the flip frame 53 and the vertical frame 51 will not change. A locking member 56 is installed on the slider of the third slide rail slider structure 55 installed on the flip frame 53; the locking member 56 includes a second straight rod motor fixed to the slider and a stop block fixed to the telescopic end of the second straight rod motor. After the flip frame 53 is adjusted to a corresponding angle, the second straight rod motor can be extended to make the stop block abut and fix against the slide rail of the third slide rail slider structure 55 to prevent it from moving on its own, thereby increasing stability.

[0057] When the inclination angle of the flipping step mechanism 2 is increased, due to the upward lifting of the flipping step mechanism 2, the positional relationship between the gear set 52 and the vertical frame 51 will change, and the gear set 52 will move upward relatively, and then under the action of the rack 57 on the vertical frame 51, the gear set 52, and when the gear set 52 rotates, under the action of the rack 57 on the flipping frame 53, the flipping frame 53 will be driven to retract downward. Since the angle of the flipping frame 53 does not change, the upper end of the flipping frame 53 will be adaptively adjusted to the connection position with the standing platform 3 under the action of the second slide rail slider structure 54, and the angle between the standing platform 3 and the flipping step mechanism 2 will also be relatively reduced. Under the dual effects of the gradual increase in the inclination angle of the flipping step mechanism 2 and the relative reduction in the angle between the standing platform 3 and the flipping step mechanism 2, the absolute angle of the standing platform 3 will not change and will always remain horizontal. Embodiment 3

Specifically, the limiting strip 334 is provided with a long groove arranged along its length direction, and the outer ends of a row of spliced ​​narrow plates 333 are rotatably installed with a rotating wheel, and the rotating wheel is located in the long groove, so that the connection point between the end of each spliced ​​narrow plate 333 and the limiting strip 334 can be rotated and displaced within a certain range; the retaining block 336 is fixed to the telescopic end of the third hydraulic telescopic rod 323, and the spring 335 is sleeved on the telescopic end of the third hydraulic telescopic rod 323, and the spring 335 is located between the extension plate 322 and the retaining block 336, and the force of the spring 335 being squeezed and deformed is greater than the force required to push the extension plate 322 to displace.

[0063] When in use, by extending the telescopic end of the third hydraulic telescopic rod 323, under the action of the spring 335, the extension plate 322 will be pushed to move first. If the limit bar 334 is parallel to the fuselage, the limit bar 334 will directly fit with the fuselage, and finally the extension plate 322 stops moving; if the outer side of the extension plate 322 is not parallel to the fuselage, one side of the limit bar 334 will first contact the fuselage, and the third hydraulic telescopic rod 323 will continue to operate, the extension plate 322 will be blocked and will not move, the spring 335 will be squeezed and compressed, and the telescopic end of the third hydraulic telescopic rod 323 will push the support rod 331, the rectangular airbag 332, a row of spliced ​​narrow plates 333 and the limit bar 334 to continue to move, the rectangular airbag 332 will be squeezed and deformed, and the row of spliced ​​narrow plates 333 will be pushed outward respectively, and finally the limit bar 334 will adapt to fit with the fuselage, so as to ensure that the standing platform 3 is close to the fuselage and the safety of the maintenance personnel is ensured.
