Description

Technical Field

[0001] This utility model belongs to the field of steel pipe pole technology, specifically a steel pipe pole flange connection device. Background Technology

[0002] Steel pipe poles are power transmission supports made of steel pipes, used for erecting high-voltage power transmission lines. They are characterized by their robust structure, strong wind and earthquake resistance, aesthetic appearance, small footprint, and ease of installation and maintenance. Their diverse designs allow for selection of different shapes and sizes to meet the needs of various lines. Flanges, as structural components connecting steel pipe poles, connect two poles together, providing reinforcement. Flanges connecting steel pipe poles typically have a large diameter, ranging from 4 to 6 meters. Currently, steel pipe pole flanges are processed by dividing them into several parts, aligning them, welding, and grinding them to form a complete flange. However, due to the large weight and volume of steel pipe pole flanges, this process is difficult, time-consuming, and labor-intensive, resulting in low flange processing efficiency. Therefore, improvements are needed to address these issues. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Depend on Figures 1 to 4 The present invention includes a base 1, which is square in shape. Four movable and adjustable triangular blocks 2 are equidistantly arranged in a ring on the top of the base 1. Each of the four triangular blocks 2 has a placement groove 3 on its top. A movable and adjustable T-shaped block 4 is installed at one end of the bottom of each of the four placement grooves 3. An arc-shaped flange 5 is provided inside each of the four placement grooves 3. The four arc-shaped flanges 5 are the same size and have the same curvature, and can be joined together to form a complete flange. Two first rollers 6 are rotatably mounted on one side of the placement groove 3, contacting the outer arc surface of the arc-shaped flange 5. A second roller 7 is rotatably mounted on one side of the upper part of the T-shaped block 4, contacting the inner arc surface of the arc-shaped flange 5. The arc-shaped flange 5 is clamped between the two first rollers 6 and the second roller 7, and can move between the two first rollers 6 and the second roller 7.

[0016] The top of the base 1 has four first sliding grooves 8 evenly spaced in a ring. Each of the four first sliding grooves 8 has a first threaded shaft 9 rotatably installed inside. Each of the four first threaded shafts 9 has a movable block 10 slidably installed inside the first sliding groove 8 connected to its surface. Four triangular blocks 2 are fixedly installed on the top of the four movable blocks 10. A first forward and reverse rotation motor 11 is installed on one side of the base 1 and connected to one end of one of the first threaded shafts 9. An inner cavity 12 is opened in the middle of the base 1. The other ends of the four first threaded shafts 9 extend into the inner cavity 12 and are fixedly installed with bevel gears 13. The four bevel gears 13 are meshed in pairs. The first forward and reverse rotation motor 11 itself has a braking structure. When the first forward and reverse rotation motor 11 is de-energized, its shaft cannot be rotated or adjusted by external force.

[0017] Specifically, four arc-shaped flange pieces 5 are placed inside four placement slots 3 respectively. Then, by moving the T-shaped block 4, the two first rollers 6 and the second roller 7 are clamped onto the arc-shaped flange pieces 5. At the same time, the position of the arc-shaped flange pieces 5 can be effectively adjusted by rotating the two first rollers 6 and the second roller 7.

[0018] Then, the first forward and reverse rotation motor 11 is started to make one of the first threaded shafts 9 rotate. The rotation of one of the first threaded shafts 9 will cause the other three first threaded shafts 9 to rotate synchronously through four meshing bevel gears 13. The rotation of the four first threaded shafts 9 will cause the four moving blocks 10 to move towards the inner cavity 12, and finally make the adjacent ends of the four arc-shaped flanges 5 abut and connect.

[0019] The bottom of each placement groove 3 is equipped with four ball bearings 14 to facilitate the movement of the arc-shaped flange 5, and one end of the bottom of each of the four placement grooves 3 is fixedly installed with a second sliding groove 15. The second threaded shaft 16 is rotatably installed inside the second sliding groove 15. The lower part of the T-shaped block 4 is threadedly connected to the second threaded shaft 16 and slidably installed inside the second sliding groove 15. Each of the four triangular blocks 2 is equipped with a second forward and reverse motor 17 connected to one end of the second threaded shaft 16. Each of the four first forward and reverse motors 11 has a braking structure. When the power to the first forward and reverse motor 11 is cut off, its shaft cannot be rotated and adjusted by external force.

[0020] Specifically, after the arc-shaped flange 5 is placed inside the placement slot 3, the second threaded shaft 16 is rotated by starting the second forward and reverse motor 17. The rotation of the second threaded shaft 16 will cause the T-shaped block 4 to drive the second roller 7 to move. At the same time, through the ball bearing 14, the arc-shaped flange 5 will eventually move and be locked between the second roller 7 and the two first rollers 6.

[0021] Each of the four T-shaped blocks 4 is equipped with a third motor 18. The output ends of the four third motors 18 are fixedly connected to the shafts of the four second rollers 7. None of the four third motors 18 have a braking structure. When the third motor 18 is de-energized, its shaft can be rotated and adjusted by external force, thereby effectively adjusting the position of the four arc-shaped flanges 5. When the four arc-shaped flanges 5 move relative to each other, their ends abut against each other and the arc-shaped flanges 5 can move and adjust automatically.

[0022] Specifically, after the arc-shaped flange 5 moves and is locked in place by the second roller 7 and the two first rollers 6, the third motor 18 is started to make the second roller 7 rotate. The rotation of the second roller 7 adjusts the position of the arc-shaped flange 5 through the two rotatable first rollers 6 and the rolling ball 14, so that the arc-shaped flange 5 is finally located in the center of the placement groove 3.

[0023] When the four arc-shaped flange pieces 5 move relative to each other, and after the four third motors 18 are de-energized, the ends of the four relatively moving arc-shaped flange pieces 5 will abut against each other. As the arc-shaped flange pieces 5 continue to move, the four arc-shaped flange pieces 5 will automatically move and adjust through the ball bearings 14, the second roller 7, and the two first rollers 6, ultimately enabling the four arc-shaped flange pieces 5 to be effectively connected to form a complete flange.

[0024] This steel pipe pole flange docking device features a fixed and movable adjustment structure as well as an automatic docking structure. The fixed and movable adjustment structure allows for convenient and effective placement and positioning of flanges, while the automatic docking structure enables efficient docking and splicing of multiple flanges, thereby significantly improving the efficiency of flange processing. Furthermore, this docking device boasts a simple structural design, is easy to use, and provides stable and reliable docking, meeting the performance requirements for steel pipe pole flange processing.
