Technical Field

[0001] The utility model relates to the technical field of reinforcement structures, in particular to a wind-resistant reinforcement structure for a power transmission tower. Background Technique

[0002] The transmission line tower is a tower-shaped building for power transmission. Their structural characteristics are that various tower types belong to space truss structures, and the members are mainly composed of single equal-angle steel or combined angle steel. Generally, two materials, Q235 (A3F) and Q345 (16Mn), are used. The connection between members adopts rough bolts, and the connection is made by the bolts bearing shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual components such as tower feet are welded by several steel plates into a combined component. Therefore, hot-dip galvanized anti-corrosion, transportation and construction erection are extremely convenient. Using power transmission towers for high-altitude operations has provided great convenience for power construction projects.

[0003] Because the power transmission tower has a certain height and is composed of members, generally several groups of members are bolted together to build a tower with a certain height. However, in some windy areas, due to the wind force, the power transmission tower will deform at the joints. After deformation, the power transmission tower will have potential safety hazards due to the instability of the joints of the members. Therefore, it is necessary to use a reinforcement structure to reinforce the joints of the members. In the prior art, generally, the connection positions of the members are thickened and thickened to make the connection positions of the members have greater supporting force. However, in some power transmission towers in windy areas, due to the need to face strong winds all year round, greater supporting force is required. Insufficient supporting force will cause the members to deform and affect the use. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-4, an embodiment provided by the present utility model: a wind-resistant reinforcement structure for a power transmission tower. The reinforcement structure includes a first connecting bar 1, a first support cross bar 11, a docking groove 9, a second connecting bar 6, and a second support cross bar 61. The first support cross bar 11 is fixedly arranged at the bottom end of the outer side of the first connecting bar 1. The first support cross bar 11 and the first connecting bar 1 are of an integral structure. The docking groove 9 is opened at both ends of the first connecting bar 1. The second connecting bar 6 is movably disassembled at both ends of the first connecting bar 1. One end of the second connecting bar 6 is fixedly provided with an extension bar 8. The extension bar 8 extends to the inner side of the docking groove 9 and engages with the docking groove 9. The second support cross bar 61 is fixedly arranged at the bottom end of the outer side of the second connecting bar 6. The second support cross bar 61 and the second connecting bar 6 are of an integral structure. A plurality of groups of first threaded holes 2 are arranged on the side wall of one side of the first connecting bar 1. The first threaded holes 2 penetrate through the first connecting bar 1 and the docking groove 9 at the same time. A second threaded hole 7 that cooperates with the first threaded holes 2 is arranged on the side wall of the extension bar 8. By passing a bolt through the second threaded hole 7 and the first threaded holes 2 at the same time, the extension bar 8 is limited to the inner side of the docking groove 9. Further, it can be explained that the extension bar 8 is pushed to one side of the docking groove 9, and the first connecting bar 1 and the second connecting bar 6 are spliced together. After splicing, the first threaded holes 2 on one side of the first connecting bar 1 are aligned and coincided with the second threaded holes 7 opened on the side wall of the extension bar 8. Then, a bolt is used to pass through the second threaded hole 7 and the first threaded holes 2 at the same time, so as to realize the limitation of the extension bar 8 to the inner side of the docking groove 9, thereby completing the assembly of the first connecting bar 1 and the threaded holes 2, enabling the power transmission tower member to fit with the inner side wall of the "L" shape formed by the second connecting bar 6 and the second support cross bar 61. At the same time, the power transmission tower member can also fit with the inner side wall of the "L" shape formed by the first connecting bar 1 and the first support cross bar 11. After fitting, the support for the power transmission tower member can be realized, and the wind resistance ability can be improved.

[0030] At both ends of the top of the second support cross bar 61, triangular support blocks two 5 are fixedly arranged. One side side of the triangular support blocks two 5 is fixedly connected to the side wall of the second connecting bar 6. At both ends of the top of the first support cross bar 11, triangular support blocks one 3 are arranged. One side of the triangular support blocks one 3 is movably connected to the side wall of the first connecting bar 1. During use, the triangular support blocks two 5 are in contact with the connection position of the power transmission tower member port. The symmetrically arranged two triangular support blocks two 5 are used to ensure the stability of the included angle between the second connecting bar 6 and the second support cross bar 61, and at the same time, support is provided at the position where the power transmission tower member port is in contact, improving the support force at the connection of the power transmission tower member.

[0031] Limit components 4 are provided at both ends of the side of the first connecting bar 1. The limit component 4 includes a sliding groove 41 opened on the side wall of the first connecting bar 1 and limit discs 42 fixed to the inner top and bottom ends of the sliding groove 41. A limit rod is connected to the side of the first triangular support block 3 close to the limit component 4. The limit rod extends into the inner side of the sliding groove 41 and contacts the limit disc 42. Further, it can be explained that the positions of the two first triangular support blocks 3 are adjusted by the limit component 4. A plurality of groups of limit discs 42 provided inside the sliding groove 41 are fixedly connected to the inner side wall of the sliding groove 41. The gaps formed between the plurality of limit discs 42 just match the inner diameter of the limit rod connected to the side of the first triangular support block 3. The first triangular support block 3 can be installed at the gap positions between different limit discs 42 by means of horizontal pushing, so as to adjust the position of the first triangular support block 3 according to the length of the power transmission tower member.

[0032] Working principle: First, push the extension bar 8 into one side of the docking groove 9 to splice the first connecting bar 1 and the second connecting bar 6. After splicing, align the first threaded hole 2 on one side of the first connecting bar 1 with the second threaded hole 7 opened on the side wall of the extension bar 8, and then use bolts to penetrate the second threaded hole 7 and the first threaded hole 2 at the same time, so as to limit the extension bar 8 inside the docking groove 9, thus completing the assembly of the first connecting bar 1 and the first threaded hole 2, enabling the power transmission tower member to fit against the inner side wall of the "L" shape formed by the second connecting bar 6 and the second support cross bar 61. At the same time, the power transmission tower member can also fit against the inner side wall of the "L" shape formed by the first connecting bar 1 and the first support cross bar 11. After fitting, the support for the power transmission tower member can be realized, improving the wind resistance. Then, the positions of the two first triangular support blocks 3 are adjusted by the limit component 4. A plurality of groups of limit discs 42 provided inside the sliding groove 41 are fixedly connected to the inner side wall of the sliding groove 41. The gaps formed between the plurality of limit discs 42 just match the inner diameter of the limit rod connected to the side of the first triangular support block 3. The first triangular support block 3 can be installed at the gap positions between different limit discs 42 by means of horizontal pushing, so as to adjust the position of the first triangular support block 3 according to the length of the power transmission tower member. The second triangular support block 5 contacts the connection position of the power transmission tower member port. The symmetrically arranged two second triangular support blocks 5 are used to ensure the stability of the angle between the second connecting bar 6 and the second support cross bar 61, and at the same time provide support at the position where the power transmission tower member port contacts, improving the support force at the connection of the power transmission tower member.
