Description

Technical Field

[0001] This utility model relates to the field of angle steel tower technology, and in particular to a large-span angle steel tower structure with good stability. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to angle steel towers is also constantly improving. Angle steel towers are often used in fields such as power line transmission, signal transmission, and signal reception. Many angle steel tower structures are large-span angle steel towers.

[0003] The large-span angle steel towers currently in use lack external anti-climbing structures, which leads to some young children climbing the towers, increasing the risk of falls and more serious injuries. This reduces the safety of the angle steel towers during use and is detrimental to their operation. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: the large-span angle steel towers currently in use lack an anti-climb structure on the outside, which leads to some young children climbing the angle steel towers, which can easily cause children to fall or even more serious incidents, reducing the safety of the angle steel towers during use and making them unsuitable for use. Therefore, this utility model proposes a large-span angle steel tower structure with good stability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stable, large-span angle steel tower structure includes an angle steel tower body, an anti-climb frame fixedly connected to the angle steel tower body, multiple rotating shafts rotatably mounted on the anti-climb frame, a torsion spring and a limiting plate fixedly connected to each rotating shaft, and anti-climb blocks arranged between the multiple limiting plates;

[0007] A U-shaped frame is provided above the anti-climb frame. A pull rope is installed on each of the rotating shafts. Multiple pull ropes are fixedly connected to the U-shaped frame. Two rotating components are provided on the anti-climb frame. Each rotating component includes a threaded rod that is threadedly connected to the anti-climb frame. A rotating block is rotatably connected to the upper end of the threaded rod. Each rotating block is fixedly connected to the U-shaped frame.

[0008] Preferably, the anti-climb frame has multiple storage slots, each of the rotating shafts is rotatably connected to the storage slot, and each of the torsion springs is fixedly connected to the inner wall of the corresponding storage slot.

[0009] Preferably, multiple reinforcing rods are fixedly connected to the angle steel tower body, and the multiple reinforcing rods are arranged in a ring array.

[0010] Preferably, each of the limiting plates has a plurality of anti-climb spikes fixedly connected to one side surface, and the plurality of anti-climb spikes are evenly and equidistantly arranged.

[0011] Preferably, a notice board is fixedly connected to one side surface of the anti-climb frame, and a warning sign is provided on the notice board.

[0012] Preferably, the bottom of the angle steel tower body is fixedly connected with multiple mounting feet, and each mounting foot has two mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Multiple limiting plates are horizontally arranged, and each limiting plate is in close contact with the surface of the anti-climb block. The multiple limiting plates can clamp the anti-climb block. Under the combined restrictive effect of multiple limiting plates, anti-climb blocks and anti-climb frames, children or other people can be prevented from climbing at will. This can effectively prevent young children from climbing the angle steel tower, thereby improving the safety of the angle steel tower during use and benefiting its use. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0022] Reference Figures 1-4 A stable, large-span angle steel tower structure includes an angle steel tower body 1, an anti-climb frame 2 fixedly connected to the angle steel tower body 1, multiple rotating shafts 11 rotatably mounted on the anti-climb frame 2, a torsion spring 13 and a limiting plate 12 fixedly connected to each rotating shaft 11, anti-climb blocks 10 arranged between the multiple limiting plates 12, a loop frame 6 arranged above the anti-climb frame 2, a pull rope 5 installed on each rotating shaft 11, multiple pull ropes 5 fixedly connected to the loop frame 6, and two rotating components arranged on the anti-climb frame 2, each rotating component including a threaded rod 7 threadedly connected to the anti-climb frame 2, a rotating block 15 rotatably connected to the upper end of the threaded rod 7, and each rotating block 15 fixedly connected to the loop frame 6.

[0023] The anti-climb frame 2 has multiple storage slots 14, each rotating shaft 11 is rotatably connected to a storage slot 14, and each torsion spring 13 is fixedly connected to the inner wall of the corresponding storage slot 14. Multiple anti-climb spikes 9 are fixedly connected to one side surface of each limiting plate 12. The multiple anti-climb spikes 9 are evenly spaced. When the U-shaped frame 6 moves vertically downward, since one end of each inelastic pull rope 5 is fixedly connected to the U-shaped frame 6 and the other end is wrapped around the corresponding rotating shaft 11, during the downward movement of the U-shaped frame 6, under the elastic force of the multiple torsion springs 13, each rotating shaft 11 will rotate and wind up the pull rope 5. The multiple limiting plates 12 will simultaneously flip downward and detach from the anti-climb block 10. The anti-climb spikes 9 on one side of the multiple limiting plates 12 will rotate into the storage slot 14, which can effectively prevent the anti-climb spikes 9 from piercing the workers.

[0024] Multiple reinforcing rods 3 are fixedly connected to the angle steel tower body 1. The multiple reinforcing rods 3 are arranged in a circular array. The multiple reinforcing rods 3 can improve the connection strength of the angle steel tower body 1, which is conducive to improving the load-bearing capacity of the angle steel tower body 1, so as to improve the stability of the angle steel tower body 1. A notice board 4 is fixedly connected to one side surface of the anti-climb frame 2. The notice board 4 is equipped with warning signs. The warning signs on the notice board 4 can remind others that the anti-climb frame 2 is equipped with anti-climb spikes 9. Do not climb it randomly and avoid being pricked by the anti-climb spikes 9.

[0025] The bottom of the angle steel tower body 1 is fixedly connected with multiple mounting feet 8. Each mounting foot 8 has two mounting holes. By passing mounting bolts through the mounting holes on each mounting foot 8 and connecting them to the mounting location, the angle steel tower body 1 can be firmly installed, resulting in good stability of the angle steel tower body 1.

[0026] In this invention, in the initial state, multiple limiting plates 12 are horizontally arranged, and each limiting plate 12 is in close contact with the surface of the anti-climb block 10. The multiple limiting plates 12 can clamp the anti-climb block 10. Under the combined restrictive effect of the multiple limiting plates 12, the anti-climb block 10, and the anti-climb frame 2, children or other people can be prevented from climbing at will. When maintenance personnel need to perform maintenance, they first rotate the two threaded rods 7 simultaneously. When each threaded rod 7 is threadedly connected to the anti-climb frame 2, it will rotate relative to the corresponding rotating block 15, which will then drive the loop frame 6 to move vertically downward. Since one end of each inelastic pull rope 5 is fixedly connected to the U-shaped frame 6, and the other end is wound around the corresponding rotating shaft 11, during the downward movement of the U-shaped frame 6, under the elastic force of multiple torsion springs 13, each rotating shaft 11 will rotate and wind up the pull rope 5. Multiple limit plates 12 will simultaneously flip downward and detach from the anti-climb block 10. Then, maintenance personnel can climb the ladder between multiple limit plates 12 for maintenance, which can effectively prevent young children from climbing the angle steel tower, thereby improving the safety of the angle steel tower during use and benefiting the use of the angle steel tower.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
