[0033] Reference Figure 1-8 A transmission tower installation assembly includes a component a1 and a component b2. A screw 31 is inserted into the component a1 and the component b2. A nut 3 is fixed at one end of the screw 31. A nut 32 matched with the screw 31 is provided at the threaded end of the screw 31 for installing and fixing the component a1 and the component b2. A sealing assembly 4 is symmetrically installed on both sides of the screw 31. When the component a1 and the component b2 are installed, it is used to seal and protect the contact part between the nut 3 and the component a1; a limiting assembly 5 is arranged in the screw 31, one end of which extends to the outside and is connected to the sealing assembly 4. When the sealing assembly 4 is running, it drives the limiting assembly 5 to move, and is used to limit the screw 31 and the components a1 and b2 to prevent loosening; a prompting assembly 6 is installed on the sealing assembly 4. When the sealing assembly 4 is running, it is used to prompt the tightness of the installation of the components a1 and the components b2.

[0034] During the installation of the transmission tower, the components are generally fixed and installed by splicing and fixing the pipes with bolt components. A small number of components are fixed by welding, but it is not convenient to disassemble and the maintenance is troublesome. The installation and disassembly method of the bolt structure is more convenient to inspect, but considering the use environment of the transmission tower, the structural accessories installed in the bottom area of ​​the tower are convenient for the staff to inspect and repair, but the bolt accessories used to connect the components at the top of the tower are eroded by rain, which is very inconvenient for the staff to repair. Therefore, in the present invention, after the screw rod 31 penetrates the component a1 and the component b2, the nut 32 is screwed to cooperate with the nut 3 to tighten and fix the components a1 and b2, and the sealing component 4 arranged between the nut 3 and the component a1 can be synchronously operated by the tightening force, so that the first airbag 48 in the sealing component 4 is expanded, and the nut 3 and the structural component a2 are tightened and fixed. The gap between the components a1 is sealed and protected, so as to prevent rainwater falling from the top of the nut 3 from leaking into the gap and causing erosion and damage to the bolt structure, thereby increasing its service life. During the sealing process of the sealing component 4, the sealing component 4 drives the limit component 5 to run synchronously, so that the limit component 5 expands inside the screw rod 31. After expansion, it fits tightly with the installation holes of the components a1 and b2, increasing its friction, playing a good limiting role, preventing loosening, and providing multiple relaxation effects. When the sealing of the sealing component 4 is completed, part of the conveying airflow generated can be used to make the prompt component 6 run synchronously, and a "click" sound of sound vibration is generated when the prompt component 6 is running, thereby prompting the installation staff to know the installation tightness of the accessories, so that the staff can unify the installation status of the accessories at each installation location.

[0035] In a preferred embodiment, referring to Figure 3 , Figure 4 , Figure 7 and Figure 8 The sealing assembly 4 includes a sliding groove 41 opened on the bottom surface of the nut 3, a sliding block 42 is slidably connected in the sliding groove 41, a lifting rod 43 is fixed to the bottom of the sliding block 42, a first piston 45 is fixed to the bottom of the lifting rod 43, the first piston 45 is slidably connected in the connecting tube 44, the connecting tube 44 is installed on the surface of the cushion block 46, the cushion block 46 is slidably connected to the surface of the screw 31, one end of the connecting tube 44 is connected to a protective member, the protective member includes an air pipe 47 connected to one end of the connecting tube 44, one end of the air pipe 47 passes through the cushion block 46 and is connected to a first air bag 48, the first air bag 48 is arranged in a limiting ring 49, the limiting ring 49 is installed on the top surface of the cushion block 46, a concave ring 491 is fixed to the bottom of the nut 3, the surrounding surfaces of the nut 3 are inclined surfaces 7, the nut 3 is a trapezoidal structure, the side surface of the cushion block 46 is inclined, and a rubber cover 8 is fixed to the bottom surface of the nut 3.

[0036] By adopting the above scheme, when the nut 32 is screwed, the screw rod 31 moves downward due to the limitation of the structure. When the screw rod 31 moves downward, the lifting rod 43 at the bottom of the nut 3 moves downward synchronously, so that the first piston 45 at the bottom of the lifting rod 43 squeezes the air inside the connecting tube 44, and part of the squeezed air is transported to the first air bag 48 through the air pipe 47, so that the first air bag 48 expands. The first air bag 48 expands to form a straight cylinder shape, which cooperates with the concave ring 491 to form a sealing protection ring, which has a good sealing and protection effect on the surrounding of the screw rod 31. When the connected and installed accessories are in the air, rainwater can flow away along the inclined surface 7 on the side of the nut 3 to prevent the accumulation of rainwater. As the rainwater continues to flow, after the gap is sealed during the operation of the sealing component 4, the rubber cover 8 moves synchronously with the downward movement of the nut 3 and fits with the side of the gasket 46, so as to form an outer layer of protection, improve the protection effect of the sealing component 4, reduce the occurrence of faults, and the falling rainwater can be well diverted.

[0037] In a preferred embodiment, referring to Figure 3 , Figure 4 and Figure 6 The limiting assembly 5 includes a shunt tube 51 fixed to the end of the connecting tube 44, the shunt tube 51 is fixed on the fixing plate 52, the fixing plate 52 is fixed on the screw 31, one end of the shunt tube 51 passes through the screw 31 and extends to the inside where a second airbag 53 is fixed, the second airbag 53 is arranged in a cavity 54, the cavity 54 is opened in the screw 31, and the surface of the screw 31 is provided with symmetrically distributed notches 55, the notches 55 are connected with the cavity 54, the surface of the shunt tube 51 is located on the fixing plate 52 and is provided with a protective layer, and the protective layer is made of wear-resistant rubber material.

[0038] By adopting the above scheme, during installation, the first piston 45 moves downward to squeeze the air in the connecting tube 44, and the connecting tube 44 is connected through the shunt tube 51. Part of the squeezed air can be transported to the shunt tube 51, and then transported to the inside of the second airbag 53 through the shunt tube 51. The second airbag 53 expands due to the delivery of gas, and a notch 55 is provided at the cavity 54. The expanded second airbag 53 is squeezed out through the notch 55 and protrudes to the outside of the screw 31, increasing the friction around the screw 31, thereby improving the upper limit effect of the screw 31 on the components a1 and b2, and preventing displacement and loosening. In this scheme, through the mutual cooperation of the sealing component 4 and the limiting component 5, the bolt structure has a good sealing effect during installation, and can also provide a better limiting effect for the middle area of ​​the bolt structure, and cooperate with the nut 32 to form a double limit, which reduces the influence of loosening of the transmission tower under vibration and other conditions and extends its service life.

[0039] It should be noted that the diverter tube 51 is made of rubber hose material, and when the screw rod 31 is displaced, the use effect of the diverter tube 51 is not affected. A protective layer is provided on the surface of the diverter tube 51 fixed on the fixed plate 52 to protect the diverter tube 51 and avoid damage during squeezing.

[0040] In a preferred embodiment, referring to Figure 4 and Figure 5 The prompt assembly 6 includes a connecting pipe 61 fixed to one end of the connecting tube 44, one end of the connecting pipe 61 passes through the cushion block 46 and is fixed with a prompt tube 62, which is installed on the cushion block 46, and the inside of the prompt tube 62 is slidably connected to the second piston 63, and a moving part is arranged on the top of the second piston 63, and the moving part includes a movable plate 66 slidably connected to the surface of the second piston 63, an arc block 67 is fixed to one side of the movable plate 66, and an extrusion spring 65 is fixed to the other side of the movable plate 66, and a fixed block 64 is fixed to the end of the extrusion spring 65, and the fixed block 64 is fixed on the surface of the second piston 63, and an acoustic part is arranged inside the prompt tube 62, and the acoustic part includes a concave block 68 fixed inside the prompt tube 62, and the concave block 68 is in a concave shape, and an arc-shaped copper sheet 69 is installed on the concave surface of the concave block 68, and a protrusion port 691 is opened on the top surface of the prompt tube 62.

[0041] By adopting the above scheme, when the gas in the connecting tube 44 is squeezed, part of the gas can be delivered to the connecting tube 61, and then delivered to the inside of the prompt tube 62. The second piston 63 slides inside the prompt tube 62 under the force of the gas pressure. As the second piston 63 moves, the arc block 67 above the second piston 63 moves synchronously. When the arc block 67 moves to contact the concave block 68, due to the structural characteristics of the concave block 68, the arc block 67 moves along the concave surface when rising. When the arc block 67 enters the concave surface of the concave block 68, the elastic squeezing force of the squeezing spring 65 causes the arc block 67 to hit the arc copper sheet 69 to make a "click" sound, providing a prompt sound, thereby conveniently reminding the installation staff that there is no need to continue tightening. Tight operation, through this design scheme, the technical difficulty of accessory installation is simplified, the installation and fixing methods of high-altitude installed connectors are unified, and the installation personnel in the prior art avoid inconsistent tightness of the bolt structure installation, which causes the structure to be overloaded and deformed or easy to loosen, thereby improving the safety performance of the transmission tower and reducing maintenance costs. At the same time, the top side of the movable plate 66 is always in contact with one side of the concave block 68 in the initial stage. When the arc block 67 contacts the concave block 68, the top of the movable plate 66 extends out of the extension port 691 to squeeze the shunt pipe 51 above, limit the backflow of the internal airflow, and improve the stability of the structure of the limit component 5, so that the prompt component 6 has a prompting function and a flow limiting function.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
