The multi-stage hydraulic cylinder 2 cooperates with the hydraulic pump and the oil storage tank 4, and the output end of the multi-stage hydraulic cylinder 2 drives the communication module 5 to rise or fall; In this embodiment, the trigger assembly needs to be operated first, and the trigger assembly is executed by each corresponding support leg 8; during the layout of the cabin body 1, the support leg 8 in the storage slot 7 is first rotated and taken out, and the support leg 8 is laid on the ground. At this time, the side wall of the support leg 8 no longer squeezes the telescopic rod 11, and the telescopic rod 11 extends out of the tube body 10 under the elastic force of the spring 14 connected thereto, as shown in FIG. Figure 6 and Figure 7 As shown, the through hole 12 on the telescopic rod 11 is also connected to the two oil holes 13 on the tube body 10. At this time, the lubricating oil in the oil pipe 6 flows along the oil pipe 6, the oil hole 13 and the through hole 12. When all the supporting legs 8 are taken out of the storage groove 7, the communication between all the through holes 12 and the oil holes 13 can be achieved. Figure 6 and Figure 7 As shown, the circulation of hydraulic oil is realized, and then the multi-stage hydraulic cylinder 2 can be driven to execute; After the support legs 8 are laid on the ground, the hydraulic oil is pumped into the hydraulic rod 9 and the multi-stage hydraulic cylinder 2 in sequence, and the output end of the hydraulic rod 9 extends out and presses against the storage slot 7, so that the support legs 8 are stably pressed against the ground.

The secondary hydraulic pump is used to provide hydraulic oil for the hydraulic motor 16 and the hydraulic rod 9. When the support legs 8 are deployed on the ground, the situation on the ground is complicated, so that the support legs 8 may not be able to be square on the ground. The support legs 8 may be arranged at an angle to the ground. In order to enable the hydraulic rod 9 to flexibly press against the side wall of the storage groove 7, a structure in which the hydraulic motor 16 cooperates with the screw rod 17 is provided. The hydraulic motor 16 drives the screw rod 17 to rotate, and the screw rod 17 can push or pull the slider 18 to move in the support leg 8. At the same time, the slider 18 drives the hydraulic rod 9 to move, and adjusts the position of the hydraulic rod 9 in the support leg 8 so that the output end of the hydraulic rod 9 can effectively press against the inner wall of the storage groove 7. As for the secondary hydraulic pump providing hydraulic oil to the hydraulic motor 16 or the hydraulic rod 9 , an oil circuit solenoid valve 15 may also be provided in the secondary hydraulic pump output oil pipe 6 to control the flow direction of the hydraulic oil and realize the hydraulic oil supply sequence in the hydraulic motor 16 and the hydraulic rod 9 .

A ball 27 is arranged on the lower surface of the lifting plate 26 to push the cabin body 1 and realize the movement of the cabin body 1. The ball 27 on the lower surface of the lifting plate 26 can also be arranged as a universal wheel, so that different movement modes can be flexibly selected. When the cabin body 1 needs to be moved, the cabin body 1 can be pushed. After the position adjustment of the cabin body 1 is completed, the sphere 27 is stored in the oil storage tank 25, so that the cabin body 1 is directly located on the ground to ensure the stability of the cabin body 1.

At this time, the cabin body 1 is pushed, and the movement of the cabin body 1 can be easily realized; when the screw rod 31 is rotated in the opposite direction, the screw rod 31 pulls the piston 30 to move, the oil storage space in the oil storage pipe 28 gradually increases, and the hydraulic pressure in the oil storage tank 25 is withdrawn. At this time, the lifting plate 26 moves into the oil storage tank 25 again, and the ball 27 no longer protrudes from the lower surface of the cabin body 1. At this time, the lower surface of the cabin body 1 is directly located on the ground; In order to ensure the sealing between the lifting plate 26 and the oil storage tank 25, and the sealing between the piston 30 and the oil storage pipe 28, sealing rings 32 are provided on the outer rings of the lifting plate 26 and the piston 30 to seal the hydraulic oil and reduce the possibility of hydraulic oil leakage.
