[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a steel structure connection device for cable fasteners on power transmission towers, comprising a tower body 101 and a steel structure connection base plate 102. Two sets of cable fastener bodies 103 are welded and fixed to the upper surface of the steel structure connection base plate 102. A fixed connection seat 105 is integrally provided at the bottom end of the steel structure connection base plate 102. Through holes 106 are provided at both ends of the fixed connection seat 105, and fixing bolts 104 are installed inside the through holes 106. Internal threaded mounting holes matching the fixing bolts 104 are formed on the surface of the tower body 101. The fixed connection seat 105 is also provided with:

[0026] The fastening mechanism is reinforced, and the fastening mechanism includes an adjustment component located at the inner edge of the perforation 106. The top of the adjustment component is provided with a compression reinforcement component, and the two ends of the adjustment component are respectively provided with a clamping reinforcement component one and a clamping reinforcement component two inside the perforation 106. After the fixing bolt 104 is installed through and rotated inside the perforation 106, the fastening mechanism will further reinforce and fix the fixing bolt 104, making it less prone to shaking and instability when subjected to wind force and tension.

[0027] To facilitate the clamping and fixing of clamping seat 1065 and clamping seat 1067 towards each other via the adjustment assembly, in this embodiment, preferably, the adjustment assembly includes a connecting groove 1064 formed at the inner edge of the through hole 106. One side of the connecting groove 1064 is located inside the fixed connecting seat 105 and is sequentially provided with a limiting groove 1069 and an internal thread groove 1061. A bidirectional screw 1060 is rotatably mounted inside the limiting groove 1069. One end of the bidirectional screw 1060 extends into the connecting groove 1064, and the other end of the bidirectional screw 1060 is fixed with an adjusting nut head 1063 inside the internal thread groove 1061. A wrench can be engaged at the end of the adjusting nut head 1063 to drive the bidirectional screw 1060 to rotate, so that when the bidirectional screw 1060 rotates, it drives the moving plate 1068 and the moving frame 10642 to move towards each other and clamp and fix.

[0028] In order to facilitate the adjustment and reinforcement installation of the adjusting nut head 1063 by means of the compression reinforcement component, in this embodiment, preferably, the compression reinforcement component includes an external thread compression post 1062 that is rotatably installed through the internal thread structure of the internal thread groove 1061. The end surface of the external thread compression post 1062 is provided with an internal hexagonal groove, so that a wrench can be engaged inside the internal hexagonal groove to rotate the external thread compression post 1062 inside the internal thread groove 1061 to compress and fix it.

[0029] In order to facilitate the clamping and reinforcement of the other side of the fixing bolt 104 by means of the clamping and reinforcement component, in this embodiment, preferably, the clamping and reinforcement component includes a limiting groove 10641 integrally formed at one end of the connecting groove 1064. A movable frame 10642 is provided inside the connecting groove 1064. A clamping seat 1067 is welded and fixed to the end of the movable frame 10642. The bidirectional screw 1060 is matched with the internal structure of the movable frame 10642. When the bidirectional screw 1060 rotates and drives the movable frame 10642 to move, the movable frame 10642 drives the clamping seat 1067 to move and clamp the other side of the fixing bolt 104 for reinforcement and installation, which facilitates strengthening the fixation.

[0030] To facilitate the compression and reinforcement installation of one side of the fixing bolt 104 using the clamping and reinforcing assembly, in this embodiment, preferably, the clamping and reinforcing assembly includes a clamping seat 1065 disposed on the other side inside the connecting groove 1064. A control groove 1066 is provided at the connection between the limiting groove 1069 and the connecting groove 1064. The end of the clamping seat 1065 extends into the interior of the limiting groove 1069 through the control groove 1066. A movable plate 1068 is welded to the ends of the two clamping seats 1065 inside the limiting groove 1069. The outer side of the bidirectional screw 1060... The surface matches the internal thread structure of the movable plate 1068. When the bidirectional screw 1060 drives the movable plate 1068 to move, the movable plate 1068 moves and drives the clamping seat 1065 to move and clamp onto one side of the fixing bolt 104 for reinforcement. The inner surfaces of the clamping seat 1065 and the clamping seat 1067 are both arc-shaped, and the inner surfaces of the clamping seat 1065 and the clamping seat 1067 are provided with tooth structure, so that the clamping seat 1065 and the clamping seat 1067 can be easily clamped onto the surface of the fixing bolt 104 for reinforcement and installation.

[0031] The positioning and reinforcement mechanism includes positioning and installation components on both sides of the fixed connecting seat 105. The positioning and installation components are equipped with rotational reinforcement components. When the fixed connecting seat 105 is closed and installed with the tower body 101, the positioning and reinforcement mechanism can conveniently position the fixed connecting seat 105 to facilitate subsequent fixed installation and strengthen the fixed use.

[0032] To facilitate the positioning and installation of the fixed connecting seat 105 using the positioning and installation assembly, and to make subsequent installation easier, in this embodiment, preferably, the positioning and installation assembly includes positioning and installation plates 1051 welded and fixed to both sides of the fixed connecting seat 105. An elastic block 1053 is fixedly installed on the inner side of the positioning and installation plate 1051 by screws. The surface of the tower body 101 is provided with a positioning groove 1054 that matches the elastic block 1053. When the fixed connecting seat 105 is closed on the surface of the tower body 101, and the positioning and installation plate 1051 is positioned and engaged, the elastic block 1053 deforms and elastically presses tightly into the inside of the positioning groove 1054 for tight positioning, which facilitates tight positioning and subsequent fixed installation.

[0033] To facilitate the positioning and reinforcement installation of the fixed connecting seat 105 and the tower body 101 by using the rotation reinforcement assembly, in this embodiment, preferably, the rotation reinforcement assembly includes a second fixing bolt 1052 disposed inside the positioning mounting plate 1051, and an internal threaded hole 1055 matching the second fixing bolt 1052 is provided at the middle position inside the positioning groove 1054. After the positioning mounting plate 1051 is tightly pressed and positioned on the surface of the tower body 101 by the fixed connecting seat 105, the second fixing bolt 1052 is rotated and inserted into the internal threaded hole 1055 to fix the positioning mounting plate 1051 and the tower body 101, which facilitates positioning and strengthens the fixed installation.

[0034] The working principle and usage process of this utility model are as follows: When using this type of power tower cable fastener steel structure connection device, the first step is to install it. The fixed connection seat 105 can be closed at the installation position on the surface of the tower body 101, and the through hole 106 is aligned with the internal threaded installation hole on the surface of the tower body 101. At this time, the rotating fixing bolt 104 passes through the through hole 106 and is embedded in the internal threaded installation hole inside the tower body 101, which facilitates the fixed installation of the fixed connection seat 105. Then, the cable is fastened through the cable fastener body 103, thereby fixing the cable fastener body 103 and the tower body 101 together through the fixed connection seat 105 and the steel structure connection base plate 102.

[0035] Then, when the fixed connecting seat 105 is installed and closed on the surface of the tower body 101, the positioning mounting plate 1051 is engaged on the side of the tower body 101. The inner surface of the positioning mounting plate 1051 is deformed by the elastic block 1053 and pressed tightly into the positioning groove 1054, thus pressing the positioning mounting plate 1051 and the tower body 101 tightly and positioning them. This facilitates the positioning and placement of the fixed connecting seat 105 before installation. The fixing bolt 1052 is rotated again and inserted into the internal threaded hole 1055 to press the positioning mounting plate 1051 tightly against the surface of the tower body 101 for reinforcement. This makes the fixed connecting seat 105 more stable after installation, and improves the convenience of positioning and reinforcing the fixed connecting seat 105 when the cable fastener body 103 is installed on the tower body 101.

[0036] Finally, after the fixing bolt 104 is installed by rotating it through the hole 106, the wrench inside the internal thread groove 1061 engages with the surface of the adjusting nut head 1063, causing the double-ended screw 1060 to rotate. This rotation of the double-ended screw 1060 simultaneously causes the moving plate 1068 to move within the limiting groove 1069, and also causes the moving frame 10642 to move within the limiting groove 10641. The moving frame 10642 then moves the clamping seat 1067, while the moving plate 1068 moves the clamping seat 1065, thus moving the clamping seat... The clamping seat 1065 and clamping seat 1067 move towards each other and clamp onto the surface of the fixing bolt 104 to reinforce its installation. This strengthens the fixing bolt 104 after it is rotated and installed. The external thread extrusion column 1062 rotates inside the internal thread groove 1061 and presses and fixes the adjusting nut head 1063 and the double-ended screw 1060 to prevent rotation under force. After installation, the bolt is less likely to loosen or become unstable when subjected to wind force and cable tension, resulting in more stable installation and safer use. This improves the reinforcement and fastening of the cable fastener body 103 on the tower body 101.
