DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0044] Reference Figure 1 - Figure 8 A hydraulic device for an emergency communication cabin includes a cabin body 1, a multi-stage hydraulic cylinder 2 is provided in the cabin body 1, an output end of the multi-stage hydraulic cylinder 2 extends upward to the outside of the cabin body 1, and a fastening buckle 3 is provided on the outer ring of the output end of the multi-stage hydraulic cylinder 2;

[0045] The cabin body 1 is further provided with a hydraulic pump and an oil storage tank 4, and the hydraulic pump is used to inject the hydraulic oil in the oil storage tank 4 into the multi-stage hydraulic cylinder 2 through the oil pipe 6;

[0046] The vertical side ribs of the cabin body 1 are provided with a receiving groove 7, in which a hollow shell-shaped support leg 8 is provided. The bottom of the support leg 8 is rotatably connected to the receiving groove 7, and a hydraulic rod 9 is provided in the support leg 8.

[0047] The cabin body 1 is further provided with a trigger assembly for controlling the flow of hydraulic oil in the oil pipe 6. The trigger assembly includes a tube body 10 with one end being closed. A telescopic rod 11 is slidably connected to the tube body 10. The end of the telescopic rod 11 extends to the side wall of the storage groove 7.

[0048] The telescopic rod 11 is provided with a through hole 12, and the through hole 12 is used to communicate with the oil hole 13 provided on the outer ring of the tube body 10. Two adjacent tube bodies 10 are connected in series through the oil pipe 6.

[0049] In this embodiment, a communication module 5 is provided at the top output end of the multi-stage hydraulic cylinder 2 to realize the communication function of the cabin 1. The multi-stage hydraulic cylinder 2 cooperates with the hydraulic pump and the oil storage tank 4. The output end of the multi-stage hydraulic cylinder 2 drives the communication module 5 to rise or fall.

[0050] 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 groove 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 outward from the tube body 10 under the elastic force of the spring 14 connected thereto. 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. Only when all the support legs 8 are removed from the storage groove 7 can all the through holes 12 be connected with the oil holes 13. 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;

[0051] After the support legs 8 are laid on the ground, hydraulic oil is pumped into the hydraulic rods 9 and the multi-stage hydraulic cylinders 2 in sequence. The output end of the hydraulic rods 9 extends and presses against the storage slots 7, stably pressing the support legs 8 against the ground. At this time, the entire cabin body 1 is in a stable state, and the output end of the multi-stage hydraulic cylinders 2 drives the communication module 5 to move upward. The communication module 5 rises to a specified height, and the stability of the cabin body 1 can be guaranteed even when laid out under harsh conditions; and a fastening buckle 3 is provided, and a draw rope is tied to the fastening buckle 3. The end of the draw rope can be fixed to the ground, or to certain stones or trees on the ground, through ground nails, to improve the stability of the communication module 5;

[0052] In order to make the oil circuit run flexibly, an oil circuit solenoid valve 15 is set at the oil inlet pipe 6 and the oil outlet pipe 6 of the oil pipe 6 to control the flow direction of the hydraulic oil. Figure 6 and Figure 7As shown, when the oil circuit solenoid valve 15 is in the open state, the hydraulic oil flows along the pipe body 10. When the oil circuit solenoid valve 15 is in the closed state, the hydraulic oil flows directly from the oil inlet pipe 6 to the oil outlet pipe 6 without passing through multiple pipe bodies 10. This situation is suitable for some situations where the layout environment is relatively good, such as some outdoor activities, where it is necessary to ensure the smooth flow of the network at the activity site. At this time, an emergency communication cabin is also needed to provide good network services. In this case, the ground is wide and flat, and the emergency communication cabin can be directly placed on the ground;

[0053] In this embodiment, the hydraulic device of the designed emergency communication cabin uses a trigger component to cooperate with the setting of the support legs 8 to realize the flow and disconnection of the hydraulic oil, which can ensure that the cabin body 1 executes the execution of the multi-stage hydraulic cylinder 2 after the layout is stable. Even if the multi-stage hydraulic cylinder 2 is executed by mistake, the communication module 5 cannot be lifted, ensuring that the cabin body 1 can be safely deployed in harsh environments.

[0054] Reference Figure 1 - Figure 9 , a hydraulic motor 16 is provided in the support leg 8, and the hydraulic motor 16 is arranged near the receiving groove 7. The output end of the hydraulic motor 16 is fixedly connected with a screw rod 17, and the screw rod 17 is threadedly connected to a slider 18, and the slider 18 is rotatably connected to the bottom of the cylinder bottom of the hydraulic rod 9;

[0055] The hydraulic motor 16 is connected to the secondary hydraulic pump through the oil pipe 6. The secondary hydraulic pump is used to provide hydraulic oil to the hydraulic motor 16 and the hydraulic rod 9. When the support legs 8 are deployed and laid on the ground, the ground conditions are complicated, so that the support legs 8 may not be square on the ground, and 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 of the hydraulic motor 16 and 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.

[0056] 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 can also be set in the secondary hydraulic pump output oil pipe 6 to control the flow direction of the hydraulic oil and realize the hydraulic oil supply order in the hydraulic motor 16 and the hydraulic rod 9.

[0057] Reference Figure 1 - Figure 11 The side wall of the receiving groove 7 is provided with a multi-layer limit groove 19; the output end of the hydraulic rod 9 is provided with a rotation groove 20, and a top block 21 is rotatably connected in the rotation groove 20. The end of the top block 21 is provided with an insert plate 22. The output end of the hydraulic rod 9 is pushed into the receiving groove 7, and the insert plate 22 is inserted into the limit groove 19;

[0058] The output end of the hydraulic rod 9 drives the top block 21 to extend into the storage groove 7, and the inserting plate 22 is inserted into the limiting groove 19, further improving the stability between the hydraulic rod 9 and the storage groove 7, and the top block 21 is rotatably connected in the rotating groove 20, which can flexibly adapt to the limiting grooves 19 of different heights. In order to ensure that the inserting plate 22 can be smoothly inserted into or pulled out of the limiting groove 19, the thickness of the inserting plate 22 is designed to be less than the internal height of the limiting groove 19, that is, the inserting plate 22 is loosely matched with the limiting groove 19, making the insertion and removal process of the inserting plate 22 easy and convenient.

[0059] Reference Figure 1 - Figure 11 A telescopic groove 23 is provided inside the output end of the hydraulic rod 9, and a push pin 24 is provided in the telescopic groove 23. The end of the push pin 24 extends into the rotating groove 20, and the push pin 24 is used to squeeze on the top block 21; the telescopic groove 23 is connected to the hydraulic pump through the oil pipe 6; the oil pipe 6 connected to the telescopic groove 23 is also connected to the oil circuit solenoid valve 15 connected to the secondary hydraulic pump. The oil circuit solenoid valve 15 is used to control the supply of hydraulic oil in the hydraulic motor 16, the hydraulic rod 9 and the telescopic groove 23. When the oil circuit solenoid valve 15 completes the oil supply to the hydraulic motor 16 and the hydraulic rod 9 in sequence, hydraulic oil is injected into the telescopic groove 23, and the hydraulic oil pushes the push pin 24 outside. The end of the push pin 24 squeezes on the top block 21, squeezing and locking the top block 21, thereby improving the stability between the insert plate 22 and the limit groove 19.

[0060] Reference Figure 1 - Figure 17 The lower end surface of the cabin body 1 is provided with a plurality of oil storage tanks 25, and a lifting plate 26 is sealingly and slidingly connected in the oil storage tank 25. A ball 27 is rotatably connected to the lower surface of the lifting plate 26, and the upper surface of the lifting plate 26 is connected to the top of the oil storage tank 25 through a compression spring 29;

[0061] An oil storage pipe 28 is provided in the cabin, and a piston 30 is sealingly and slidingly connected to the oil storage pipe 28. One end of the piston 30 is rotatably connected to a screw 31, and the end of the screw 31 extends outside the cabin body 1. The oil storage pipe 28 is connected to the oil storage tank 25 through multiple oil pipes 6.

[0062] The oil reservoir 25 stores hydraulic oil, and the oil pressure of the hydraulic oil is used to support the lifting plate 26. The spheres 27 are provided 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 spheres 27 on the lower surface of the lifting plate 26 can also be provided as universal wheels, so that different movement modes can be flexibly selected.

[0063] 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 ball 27 is stored in the oil storage tank 25, so that the cabin body 1 is directly placed on the ground to ensure the stability of the cabin body 1. The ball 27 is moved up relative to the cabin body 1 into the oil storage tank 25. The specific operation is to use a socket wrench to rotate the screw 31, the screw 31 rotates and moves into the oil storage pipe 28, and the screw 31 pushes the piston 30 to move. The piston 30 injects the hydraulic oil in the oil storage pipe 28 into the oil storage tank along the multiple oil pipes 6. 25, the hydraulic oil in the oil storage tank 25 gradually increases and pushes the lifting plate 26 outward. The lifting plate 26 pushes the ball 27 into the oil storage tank 25. At this time, the cabin body 1 is pushed and the cabin body 1 can be easily moved. 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 back into the oil storage tank 25, 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 on the ground.

[0064] 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.

[0065] Reference Figure 1 - Figure 9 The bottom of the storage tank 7 is horizontally connected to a swivel 33, and the swivel 33 is rotatably connected to the support leg 8;

[0066] The swivel 33 is connected to the bottom of the storage slot 7 by rotating in the horizontal direction, and the swivel 33 is connected to the support leg 8 by rotating. After the support leg 8 is laid out, it can be swung and adjusted in the horizontal plane, that is, the two-dimensional angle adjustment of the support leg 8 is achieved, so that the support leg 8 can be laid out on the ground and then swung horizontally, so that the support leg 8 is laid out in a relatively flat area on the ground, thereby improving the stability of the support leg 8 itself after being laid out, and also improving the stability of the cabin body 1.

[0067] Reference Figure 1 - Figure 8 The end side wall of the support leg 8 is rotatably connected to an L-shaped fixing plate 34. The upper end edge of the cabin body 1 is provided with a slot 35 adapted to fit the fixing plate 34. The support leg 8 is rotated into the receiving slot 7, and the fixing plate 34 is rotated and embedded in the slot 35.

[0068] When the cabin body 1 is not in use, the support leg 8 is rotated into the storage slot 7, and then the fixing plate 34 is rotated and embedded in the card slot 35. At this time, the support leg 8 can be stably stored. At the same time, the fixing plate 34 can also cooperate with the fastening buckle 3 through a pull rope, and one end of the pull rope is tied to the fixing plate 34, and the other end of the pull rope is tied to the fastening buckle 3, providing multi-angle pulling for the communication module 5 on the multi-stage hydraulic cylinder 2, and is suitable for the situation where there is no weight on the ground to tie the pull rope. Relying on the support of the cabin body 1 and the support leg 8 itself on the ground, a stable pulling force is provided for the pull rope and the communication module 5.

[0069] Reference Figure 5 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 The outer ring of the output end of the multi-stage hydraulic cylinder 2 is provided with a ring body 36, and an annular groove 40 is provided on the outer ring of the ring body 36. The notch of the annular groove 40 is tilted downward, and a plurality of T-shaped fastening buckles 3 are rotatably connected in the annular groove 40;

[0070] After the support leg 8 is laid out on the ground, it is deflected and adjusted in the horizontal direction. In order to make the support leg 8, screw rod 17, hydraulic rod 9, pull rope and fastening buckle 3 bear forces on the same plane and ensure that the pull rope has a stable pulling force, the communication module 5 is stabilized, and the fastening buckle 3 is designed to be rotatably connected in the annular groove 40 on the ring body 36, so that the fastening buckle 3 can adjust its position according to the pulling direction of the pull rope, ensuring that the support leg 8, screw rod 17, hydraulic rod 9, pull rope and fastening buckle 3 bear forces on the same plane, so that the pull rope can stably pull the output end of the multi-stage hydraulic cylinder 2.

[0071] Reference Figure 5 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 , a plurality of semicircular grooves 37 are provided on the inner side wall of the annular groove 40; a protrusion 38 adapted to the semicircular groove 37 is provided at the inner end of each fastening buckle 3;

[0072] After the pull rope is pulled and tightened, the protrusion 38 on the fastening buckle 3 is embedded in the semicircular groove 37, which constrains the relative rotation between the fastening buckle 3 and the annular groove 40. Even if a strong wind subsequently hits the communication module 5, the vibration generated will not affect the fastening buckle 3 and its position in the annular groove 40, that is, the support leg 8, the screw rod 17, the hydraulic rod 9, the pull rope and the fastening buckle 3 are still on the same plane.

[0073] Reference Figure 5 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15The outer ring of the ring body 36 is threadedly connected with a fastening bolt 39, and the end of the fastening bolt 39 passes through the ring body 36 and presses against the outer ring of the output end of the multi-stage hydraulic cylinder 2;

[0074] The ring body 36 is mounted on the output end of the multi-stage hydraulic cylinder 2 by tightening bolts 39 , which facilitates the disassembly of the ring body 36 and the adjustment of the position of the ring body 36 on the output end of the multi-stage hydraulic cylinder 2 .

[0075] Working principle: During the installation of the cabin 1, the supporting legs 8 in the receiving slots 7 are first rotated out and laid on the ground. At this time, the side walls of the supporting legs 8 no longer squeeze the telescopic rods 11. The telescopic rods 11 extend outward from the tube body 10 under the elastic force of the springs 14 connected thereto. 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. Only when all the support legs 8 are removed from the storage groove 7 can all the through holes 12 be connected with the oil holes 13. Figure 6 and Figure 7 As shown, the circulation of hydraulic oil is realized, and then the hydraulic motor 16, hydraulic rod 9, ejector pin 24 and multi-stage hydraulic cylinder 2 can be driven in sequence to perform;

[0076] When driving the hydraulic motor 16, the hydraulic rod 9 and the ejector pin 24; the hydraulic oil is controlled by the oil circuit solenoid valve 15 to drive the hydraulic motor 16 to execute, adjust the position of the hydraulic rod 9 in the support leg 8, and then drive the hydraulic cylinder to execute, so that the output end of the hydraulic cylinder can drive the ejector block 21 to push into the receiving groove 7, and insert the insert plate 22 into the limiting groove 19, and then drive the ejector pin 24, which squeezes the ejector block 21 to stabilize it;

[0077] Next, the multi-stage hydraulic cylinder 2 is driven to execute, and the output end of the multi-stage hydraulic cylinder 2 drives the communication module 5 to move upward, and the communication module 5 rises to the specified height. Even if it is deployed under harsh conditions, the stability of the cabin body 1 can be guaranteed.
