A rotary joint 10 is installed above the first adjusting tube 11, and a second adjusting tube 27 is installed above the rotary joint 10. The second adjusting tube 27 is connected to a second connecting tube 23 and can move inside the second connecting tube 23.

[0025] In this embodiment: the connecting cylinder 4 and the first connecting bearing 14 connect the second connecting pipe 23 and the first connecting pipe 13 together. In this way, the gravity of the inner arm 2 and the forces in other directions will act on the connecting cylinder 4 and the first connecting bearing 14, avoiding these forces acting on the rotary joint 10 and causing the rotary joint 10 to be damaged and leak due to stress. At the same time, a second adjusting pipe 27 that can extend and retract inside the second connecting pipe 23 and a connecting ball 12 that can rotate inside the first connecting pipe 13 are provided. When the connecting cylinder 4 is deformed by force, the rotary joint 10 can adjust its own angle to avoid the force acting on the rotary joint 10 when the connecting cylinder 4 is deformed.

[0029] In the embodiment, when the connecting cylinder 4 is deformed and the connecting ball 12 rotates in any direction inside the movable ball groove 25, the limiting movable ring 29 can move inside the limiting movable groove 26, ensuring the communication between the second adjusting pipe 27 and the second connecting pipe 23 while avoiding stress between the second adjusting pipe 27 and the second connecting pipe 23.

[0030] Further, In an alternative embodiment, the first bevel gear 15 is installed on the outer surface of the first connecting pipe 13, the second bevel gear 17 is installed on both sides of the first bevel gear 15, the second connecting bearing 16 is installed on the side of the second bevel gear 17 away from the first bevel gear 15, the air cylinder 19 is installed above the second bevel gear 17, the piston 32 is movably installed inside the air cylinder 19, the transmission rod 18 is installed below the piston 32, the movable shaft 33 is installed below the transmission rod 18, the gas delivery hose 21 is connected to one side of the air cylinder 19, the first one-way valve 20 is connected to the other end of the gas delivery hose 21, the gas outlet pipe 31 penetrates through the inside of the piston 32, and the second one-way valve 30 is installed below the gas outlet pipe 31.

[0031] In the embodiment, when the first connecting pipe 13 rotates, the piston 32 moves back and forth inside the air cylinder 19, thereby pumping external gas into the connecting cylinder 4, accelerating the flow of gas inside the connecting cylinder 4, playing a certain heat dissipation role, and reducing the accumulation of friction heat.

[0032] Further, In an alternative embodiment, the second bevel gear 17 is movably connected with the connecting cylinder 4 through the second connecting bearing 16, and the second bevel gear 17 is meshingly connected with the first bevel gear 15.

[0033] In this embodiment: when the first connecting pipe 13 rotates, the second bevel gear 17 can be driven to rotate by the first bevel gear 15, and the horizontal rotating force of the first connecting pipe 13 is converted into vertical rotating force.

[0034] Furthermore, In an optional embodiment, the transmission rod 18 is movably connected with the second bevel gear 17 through the movable shaft 33, and the piston 32 is moved in the air cylinder 19 through the second bevel gear 17 and the transmission rod 18.

[0035] In this embodiment: when the second bevel gear 17 rotates, the rotating force is converted into vertical push-pull force through the movable shaft 33 and the transmission rod 18, and then the piston 32 is pushed to move back and forth in the air cylinder 19.

[0036] Furthermore, In an optional embodiment, the air cylinder 19 is communicated with the first one-way valve 20 through the air conveying hose 21, and the first one-way valve 20 is fixedly connected with the connecting cylinder 4.

[0037] In this embodiment: when the piston 32 moves downward in the air cylinder 19, the air outside enters the air cylinder 19 through the first one-way valve 20 and the air conveying hose 21.

[0038] Furthermore, In an optional embodiment, the connecting plate 22 is fixedly installed above the air cylinder 19, the connecting plate 22 is movably connected with the connecting cylinder 4 through the connecting shaft 34 which is arranged in the connecting plate 22.

[0039] In this embodiment: when the piston 32 moves downward in the air cylinder 19, the air cylinder 19 is driven to rotate, and the connecting plate 22 and the connecting shaft 34 ensure that the air cylinder 19 follows the transmission rod 18 to swing in the connecting cylinder 4.

[0040] In summary, the adjustment system for the industrial crane pipe based on the intelligent filling is used. First, the inner arm 2 needs to be rotated when adjusting the position of the vertical pipe. The inner arm 2 drives the first connecting pipe 13 to rotate. The inner arm 2 provides an additional force to the first connecting pipe 13. The force acts on the connecting cylinder 4 and the first connecting bearing 14. The first connecting pipe 13 drives the rotary joint 10 to rotate through the first adjusting pipe 11 and the connecting ball 12. When the rotary joint 10 rotates, internal friction generates a certain amount of heat. Then, the first connecting pipe 13 drives the first bevel gear 15 to rotate. The first bevel gear 15 drives the second bevel gear 17 to rotate. The rotating second bevel gear 17 drives the piston 32 to move up and down in the air cylinder 19 through the movable shaft 33 and the transmission rod 18. When the piston 32 moves upward in the air cylinder 19, the gas in the air cylinder 19 enters the inside of the connecting cylinder 4 through the gas outlet pipe 31 and the second one-way valve 30. The excess gas in the connecting cylinder 4 is discharged through the air hole 8. The heat in the connecting cylinder 4 is taken out. When the piston 32 moves downward in the air cylinder 19, the air outside enters the inside of the air cylinder 19 through the first one-way valve 20 and the air supply hose 21. Secondly, when the connecting cylinder 4 deforms, the first connecting pipe 13 and the second connecting pipe 23 are not in the same straight line. The connecting ball 12 rotates in the movable ball groove 25 in the first connecting pipe 13 to avoid the force generated by the deformation acting on the rotary joint 10. Thirdly, when the adjustment structure composed of the connecting cylinder 4 and the components inside it needs to be replaced, the second connecting flange 5 and the third connecting flange 7, as well as the first connecting flange 3 and the fourth connecting flange 9, can be disassembled. The rotary joint 10 is a prior art and is a commonly used rotary joint 10 in traditional crane pipes. Therefore, it is not described here.

[0041] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application.
