Technical Field

[0001] This utility model relates to the field of polyurethane single-tube tower technology, specifically to a segmented plug-in polyurethane single-tube tower. Background Technology

[0002] Polyurethane single-tube towers are single-tube tower structures manufactured with polyurethane composite materials as the core. They are mainly used in fields such as communications, environmental protection, and municipal engineering to undertake signal transmission and other tasks. When existing polyurethane single tubes are spliced, they are generally connected by connecting flanges and bolts and nuts at their ends. However, due to the large number of connecting holes inside the flange, a large number of bolts and nuts need to be tightened. When splicing multiple sections of single-tube towers, it takes a lot of time for operators to tighten the bolts, increasing labor costs and reducing the splicing efficiency of polyurethane single-tube towers.

[0003] Therefore, we propose a segmented plug-in polyurethane single-tube tower to solve the above problems. Utility Model Content

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a segmented plug-in polyurethane single-tube tower.

[0019] This utility model provides, for example Figure 1-3 The illustrated segmented plug-in polyurethane single-tube tower includes a tube tower 1 and flanges 2 located at both ends of the tube tower 1. A plug-in pipe 8 is fixedly installed at the lower end of the inner wall of each tube tower 1, and the plug-in pipe 8 is plugged into the interior of the tube tower 1. Each flange 2 has multiple radially evenly distributed connection holes 3 inside, and adjacent flanges 2 are in contact with each other. A bolt rod 4 passes through the connection holes 3 inside adjacent flanges 2. A positioning hole 5 is opened on the wall of the bolt rod 4, and a stop block 6 slides through the positioning hole 5. A guide support mechanism for supporting the movement of the stop block 6 is provided between the stop block 6 and the flange 2. The guide support mechanism includes a guide groove 9 opened at the top of the flange 2, and a guide rod 10 fixedly installed on the inner wall of the guide groove 9. The guide rod 10 is a T-shaped rod, and a connecting rod 11 is slidably sleeved on the wall of the guide rod 10. The upper end of the connecting rod 11 is fixedly connected to the stop block 6. A spring 12 is sleeved on the wall of the guide rod 10, and both ends of the spring 12 are fixedly connected to the guide rod 10 and the connecting rod 11, respectively.

[0020] In order to enable multiple connecting rods to move simultaneously and drive the stop block into the positioning hole, such as Figure 2-3 As shown, each pipe tower 1 has an annular groove 7 on the outside of one end near its bottom flange 2. The annular groove 7 is provided with a push-in mechanism for moving the stop block 6. The push-in mechanism includes an internal threaded ring 13. The inner wall of the annular groove 7 is provided with a rotating thread 14, which is configured to cooperate with the internal threaded ring 13. The outer wall of the internal threaded ring 13 is fixed with a plurality of radially evenly distributed conical push plates 15. The conical push plates 15 are configured to cooperate with the connecting rod 11. The side wall of the connecting rod 11 near the conical push plate 15 is provided with a mating inclined surface 16.

[0021] Working principle: When splicing segmented pipe towers, first insert the insertion pipe 8 at the top of the next pipe tower 1 into the inner wall of the previous pipe tower 1, so that the two pipe tower 1s are initially connected and positioned by the insertion pipe 8. At this time, the flanges 2 at the ends of the two pipe tower 1s are in close contact, and the connection holes 3 on the two flanges 2 correspond one to one. Then, the bolt rods 4 are passed through the aligned connection holes 3 in sequence to complete the initial connection of the adjacent flanges 2. Then, the internal threaded ring 13 in the annular groove 7 is rotated. Since the inner wall of the annular groove 7 has a rotating thread 14 that mates with the internal threaded ring 13, the internal threaded ring 13 will move along the axial direction of the annular groove 7, causing multiple tapered push plates 15 fixed on its outer wall to move synchronously. During the movement of the tapered push plates 15, their inclined surfaces contact the mating inclined surfaces 16 on the connecting rod 11 and apply a pushing force, pushing the connecting rod 11 to slide along the guide rod 10 in the guide groove 9 towards the bolt rod 4. The spring 12 is stretched, and the upper end of the connecting rod 11 is fixedly connected to the stop block 6. Therefore, the stop block 6 will move synchronously with the connecting rod 11 and finally insert into the positioning hole 5 on the bolt rod 4 wall to axially limit the bolt rod 4 and prevent the bolt rod 4 from coming out of the connecting hole 3, thus quickly completing the fixed splicing of two adjacent pipe tower sections 1. If the tower needs to be disassembled, rotate the internal threaded ring 13 in the opposite direction. The tapered push plate 15 moves in the opposite direction with the internal threaded ring 13, and the thrust on the connecting rod 11 disappears. The spring 12 resets and pulls the connecting rod 11 to slide in the opposite direction along the guide rod 10, causing the stop block 6 to come out of the positioning hole 5 and release the limit on the bolt rod 4. At this time, the bolt rod 4 can be taken out from the connecting hole 3, and then the insertion pipes 8 of the two sections of the tower 1 can be separated to complete the tower disassembly.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
