Description

Technical Field

[0001] This utility model relates to the field of overhead line device technology, and more specifically, to an overhead line device for power engineering construction. Background Technology

[0002] In power engineering construction, the importance of overhead line equipment is self-evident. It is the key foundation for achieving stable power transmission. By accurately positioning and firmly fixing the wires, it ensures that the current can be smoothly transmitted from the generation end to the user end.

[0003] Chinese patent application CN212923865U discloses a power line stringing device for power engineering construction. This device, belonging to the field of power line stringing devices, includes a mobile walking device with two symmetrically arranged lifting devices on it. A wire-laying device is installed between the two lifting devices, forming a 20-degree angle with the horizontal direction and equipped with wire rollers. This technical solution, through its height-based wire-laying design, reduces traffic interference during road crossing operations. Its autonomous walking function ensures the continuity of the stringing operation. Furthermore, due to the height-based wire-laying setting, the wire can be directly placed at the stringing position, eliminating the need for tensioning after laying, saving time and reducing labor intensity. However, this solution has certain limitations. Its walking frame is only suitable for walking and placing on flat ground. In actual stringing processes, uneven ground is a common occurrence. When this walking frame is placed on uneven ground, supporting the stringing wheels or wire rollers, it is prone to swaying and lacks stability. Therefore, this application proposes a power line stringing device for power engineering construction to effectively solve the above problems. Utility Model Content

A connecting pipe 13 is rotatably connected to the side of the support frame 2, and a connecting rod 14 is movably installed inside the connecting pipe 13. The connecting rod 14 moves within the connecting pipe 13. A plug pipe 17 is fixedly connected to the chassis 1, and the connecting rod 14 and the plug pipe 17 are movably installed. The plug pipe 17 supports the vertical state of the support frame 2.

[0031] A first pin 8 is movably connected to the support frame 2. An installation sleeve 3 and a support sleeve 5 are movably installed on the support frame 2 above the first pin 8. The first pin 8 supports the installation sleeve 3. The support sleeve 5 is located above the installation sleeve 3. A cylinder 4 is fixedly connected to the installation sleeve 3. The output shaft of the cylinder 4 is fixedly connected to the support sleeve 5. The cylinder 4 pushes the support sleeve 5, making it easy to adjust the height of the support sleeve 5, thereby adjusting the height of the cable tray 7.

[0032] A support roller 6 is rotatably connected inside the support tube sleeve 5. A support tube is movably installed between the support rollers 6. The wire rack 7 is rotatably connected to the support tube. The support rollers 6 are located on both sides of the support tube to support the support tube, and the rotatable connection makes it easy for the support tube to rotate.

[0033] A connecting sleeve 11 is fixedly connected to the side of the support sleeve 5. An anti-detachment locking post 12 is rotatably connected inside the connecting sleeve 11. The anti-detachment locking post 12 and the connecting sleeve 11 cannot be separated. The upper end of the connecting tube 13 is inserted into the connecting sleeve 11 and fixedly connected to the anti-detachment locking post 12, so that the anti-detachment locking post 12 and the connecting sleeve 11 rotate synchronously. A locking bolt 18 is threadedly connected to the lower part of the connecting tube 13. A hole groove is provided on the connecting rod 14 corresponding to the position of the locking bolt 18. The locking bolt 18 is inserted into the hole groove to fix the connecting rod 14.

[0034] A connecting frame 16 is fixedly connected to the chassis 1, and a plug pipe 17 is fixedly connected to the connecting frame 16. A curved rod 15 is provided on the side of the support frame 2. The two ends of the curved rod 15 are fixedly connected to the connecting rod 14 respectively. The curved rod 15 makes it easy for the connecting rods 14 on both sides of the support frame 2 to move up or down synchronously. The connecting rods 14 connected to the curved rod 15 are located on both sides of the same support frame 2. A support seat 9 is fixedly connected to the chassis 1. The support seat 9 is rotatably connected to the lower end of the support frame 2 through the bearing 10, so that the support frame 2 can rotate through the bearing 10.

[0035] The steps for using this utility model are as follows: When the support frame 2 and the base 1 are perpendicular to each other, the lower end of the connecting rod 14 is inserted into the insertion pipes 17 on both sides of the support frame 2. When placed on an uneven ground, the first locking bolt 18 is unscrewed to release the fixing constraint of the connecting rod 14. The corresponding curved rod 15 is then pulled upward, causing the connecting rods 14 at both ends of the curved rod 15 to move out of the corresponding insertion pipes 17. Then, the support frame 2 is rotated forward on the support base 9 via the bearing 10, and the curved rod 15 is pulled forward, causing the curved rod 15 to drive the connecting rod 14 towards... When the connecting rod 14 rotates forward, the connecting tube 13 on the connecting rod 14 rotates synchronously, causing the anti-loosening locking post 12 at the upper end of the connecting tube 13 to rotate synchronously in the connecting sleeve 11. Then, the connecting rod 14 is inserted into the ground or rests against the ground. By tightening the first locking bolt 18 again, the connecting rod 14 is fixed in the connecting tube 13. The connecting tube 13 and the connecting rod 14 support the support frame 2, making it easy for the overhead line device to be installed on uneven ground. By adjusting the angle, the two ends of the support tube are kept on the same horizontal line, and the overhead line reel 7 on it is installed stably, improving the applicability of the overhead line device.

[0036] Example 2, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The difference from the basic embodiment 1 is that a turntable 22 is rotatably connected to the chassis 1. The turntable 22 facilitates the adjustment of the angle of the convex extension frame 19 by rotation. Extension tubes 23 are fixedly connected to both sides of the turntable 22. Extension rods 20 are fixedly connected inside the extension tubes 23. One end of the extension rods 20 is fixedly connected to the convex extension frame 19. The overall length of the extension rods 20 and the extension tubes 23 is easy to adjust.

[0037] A bracket 25 is fixedly connected to the chassis 1, and a turntable 22 is rotatably connected to the bracket 25. The bracket 25 allows the turntable 22 to rotate on it, and the bracket 25 restricts the turntable 22 downward so that the turntable 22 cannot be detached from the bracket 25. A second pin 26 is movably installed at the upper part of the bracket 25. Several positioning holes 27 are opened on the turntable 22. The lower end of the second pin 26 is movably installed with the positioning holes 27, and the second pin 26 fixes and limits the turntable 22.

[0038] One end of the extension tube 23 is threaded with a second locking bolt 24. The extension rod 20 has a locking groove 21. The lower end of the second locking bolt 24 is movably installed in the locking groove 21, so that the second locking bolt 24 fixes the extension rod 20.

[0039] The steps for using this utility model are as follows: In this overhead line device, the convex extension bracket 19 on the side of the chassis 1 is easy to adjust in position and length. Rotate the turntable 22 on the bracket 25 so that the extension tubes 23 on both sides of the turntable 22 change their angles synchronously. The extension tubes 23 drive the extension rod 20 and the convex extension bracket 19 to change their positions synchronously. Insert the second locking bolt 24 into the bracket 25 and continue to insert it downward into the corresponding positioning hole 27 on the turntable 22 so that the angle and position of the turntable 22 are limited. Then loosen the second locking bolt 24 so that the extension rod 20 moves in the extension tube 23, thereby changing the length of the convex extension bracket 19. When the convex extension bracket 19 moves to the appropriate position, screw the second locking bolt 24 into the corresponding locking hole groove 21 so that the extension rod 20 is fixed.
