DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] See also Figure 1-4 In this embodiment, a transmission tower installation auxiliary device includes a fixed frame 1 and a mounting frame 2 located on the fixed frame 1. A take-up wheel 4 is rotatably installed in the fixed frame 1 through a bearing. A connecting shaft 3 runs through the middle of the take-up wheel 4. One end of the connecting shaft 3 extends to the outside of the fixed frame 1 and is connected to the power end of the motor 17. The take-up wheel 4 is driven by the motor 17 to rotate relative to the fixed frame 1, so that the transmission line can be tightened and pulled.

[0030] The take-up wheel 4 in this embodiment is also provided with a wiring structure for connecting the power transmission line, and the wiring structure includes a wire end clamp 8 movable on the outside of the take-up wheel 4, and a wire threading opening 5 is opened through the outside of the take-up wheel 4. The wire end clamp 8 corresponds to the position of the wire threading opening 5. Through the movable wire end clamp 8, the power transmission line can be clamped at the wire threading opening 5 to limit the position of the power transmission line.

[0031] Preferably, there are several threading openings 5, which are arranged in a circle at equal distances on the take-up wheel 4, so that the power transmission line can be conveniently fixed to the take-up wheel 4 at different positions.

[0032] It should be noted that a circular arc-shaped guide block 6 is fixedly installed on the outside of the take-up wheel 4, and a U-shaped sliding block 7 is fixedly installed on the outside of the thread end clamp 8. Through the relative sliding of the sliding block 7 and the guide block 6, the thread end clamp 8 can easily fix the thread end extending to the threading port 5.

[0033] It is worth noting that the sliding block 7 has a friction pad, so that when the sliding block 7 slides relative to the guide block 6, the sliding position can be maintained.

[0034] In order to facilitate the connection of the fixing frame 1 to the transmission tower, in this embodiment, the mounting frame 2 is U-shaped as a whole with an opening at the upper end, so that the mounting frame 2 can be buckled upward on a single beam of the transmission tower, and sliding grooves 9 are opened on both side walls of the mounting frame 2, and a fixing structure for fixing is provided on the mounting frame 2.

[0035] In this embodiment, the fixing structure includes a slide plate 10 slidably connected to the slide groove 9 on the mounting frame 2. The size of the slide plate 10 corresponds to the size of the middle part of the mounting frame 2. The extended mounting frame 2 can be connected and fixed by sliding the slide plate 10 relative to the inner wall of the mounting frame 2.

[0036] It should be noted that both ends of the skateboard 10 extend with extension portions 11 corresponding to the slide groove 9, the extension portions 11 slide relative to the slide groove 9, and threaded rods 13 are fixedly installed on the extension portions 11 at both ends of the skateboard 10, and the outer side of the upper end of the mounting frame 2 extends outward in an L shape to form a bending portion 12, and the threaded rod 13 penetrates and is slidably connected to the bending portion 12.

[0037] In a specific implementation, by threading a nut on the threaded rod 13 penetrating into the mounting frame 2 , the mounting frame 2 can be connected and fixed relative to the transmission tower.

[0038] In this embodiment, a rotating disk 14 is rotatably connected to the lower end of the mounting frame 2, and a hinge 15 connected to the fixed frame 1 is hinged on the lower end of the rotating disk 14, so that the rotating disk 14 can swing relative to the fixed frame 1, thereby improving the flexibility of connecting the fixed frame 1 to the transmission tower.

[0039] In this embodiment, a soft pad 16 is fixedly mounted on the inner bottom wall of the mounting frame 2 , and the soft pad 16 can reduce the wear caused by the contact between the transmission tower and the mounting frame 2 .

[0040] The working principle of the above embodiment is:

[0041] After the user carries the fixing frame 1 to the top of the transmission tower, the mounting frame 2 is sleeved on the outer position of the extension rod of the transmission tower. At this time, the slide plate 10 is fixed relative to the mounting frame 2 by rotating the nut, so that the fixing frame 1 can be fixed relative to the transmission tower. At this time, the mounting frame 2 can be rotated relative to the fixing frame 1 to adjust the angle. After one end of the transmission line and the threading hole 5 on the take-up wheel 4 are passed through relative to each other, the sliding block 7 and the wire end clamp 8 located outside the take-up wheel 4 are slid, so that the wire end clamp 8 restricts the transmission line from being clamped. At this time, the motor 17 is controlled to drive the take-up wheel 4 to rotate, so that the transmission line outside the take-up wheel 4 can be wound and tightened.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0043] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
