Description

Technical Field

[0001] This utility model relates to the field of power transmission tower installation technology, specifically a modular tower body connection structure for a three-circuit power transmission tower. Background Technology

[0002] Power transmission towers are tower-shaped structures used for power transmission. Their structural characteristics are that all tower types are spatial truss structures, with the main members consisting of single equilateral angle steel or combined angle steel. The connections between the members are made of coarse bolts, which are connected by shear force. The entire tower is composed of angle steel, connecting steel plates, and bolts. Some components, such as the tower feet, are made by welding several steel plates into a single assembly. Therefore, hot-dip galvanizing for corrosion protection, transportation, and construction are extremely convenient.

[0003] However, the existing steel pipe tower connection structure is relatively simple. When there is a need to connect towers of different specifications or towers with installation errors, it is necessary to replace parts, which reduces work efficiency. Therefore, we propose a more convenient and practical connection structure to meet the usage requirements. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular tower body connection structure for a three-circuit transmission tower, including a connection mechanism for connecting the tower body. The connection mechanism includes a fixed frame, a fixed plate fixedly connected to the inner wall of one side of the fixed frame, a through hole opened at the top center of the fixed plate, a rotating tube rotatably connected inside the through hole, a rotating ring fixedly connected to the outer wall of the rotating tube, and screws threaded to both ends of the rotating tube. Support mechanisms are provided on both sides of the fixed frame for supporting the tower body.

[0006] Furthermore, a sliding frame is rotatably connected to one end of the screw, connecting blocks are fixedly connected to both sides of the sliding frame, and an installation block is slidably connected to one side of the connecting blocks.

[0007] Furthermore, the sliding frame has through holes on both sides of its bottom, and fixing bolts are installed in the through holes. The fixing bolts pass through the mounting block, and a mounting plate is fixedly connected to the top of the mounting block.

[0009] Furthermore, a through hole is provided at the center of the top of the reinforcing plate, and a rotating rod is rotatably connected inside the through hole. A turntable is fixedly connected to one end of the rotating rod, and a plurality of equidistant through holes are provided on the top of the turntable.

[0018] 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.

[0019] During the installation of power transmission towers, connecting equipment is required. The connecting equipment provided by this utility model is specifically designed for tower body connection operations during the installation of power transmission towers. Before using this equipment for connection operations, it is essential to ensure that all components are intact to avoid safety hazards during installation. When fixing the connecting mechanism 1 to the tower body, ensure that the fixing frame 101 fits tightly against the tower body, and that the contact area between the fixing plate 102 and the tower body is sufficiently large to improve connection stability. When adjusting the rotating ring 104 and the screw 105, proceed gradually to avoid excessive force that could damage components or cause unstable connections. When installing the sliding frame 106 and the connecting block 107, ensure that they can be correctly engaged with the tower body for secondary fixing. At the same time, check that the fixing bolts 109 are tightened to ensure connection stability.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a modular tower body connection structure for a three-circuit power transmission tower, including a connection mechanism 1 for connecting the tower body. The connection mechanism 1 includes a fixing frame 101, a fixing plate 102 fixedly connected to the inner wall of one side of the fixing frame 101, a through hole opened in the center of the top of the fixing plate 102, a rotating tube 103 rotatably connected in the through hole, a rotating ring 104 fixedly connected to the outer wall of the rotating tube 103, and screws 105 threadedly connected to both ends of the rotating tube 103. Support mechanisms 2 are provided on both sides of the fixing frame 101 for supporting the tower body.

[0021] like Figure 2 As shown, a sliding frame 106 is rotatably connected to one end of the screw 105. Connecting blocks 107 are fixedly connected to both sides of the sliding frame 106. An mounting block 108 is slidably connected to one side of the connecting block 107. Through holes are opened on both sides of the bottom of the sliding frame 106. Fixing bolts 109 are installed in the through holes. The fixing bolts 109 pass through the mounting block 108. A mounting plate 110 is fixedly connected to the top of the mounting block 108.

[0022] It should be noted that during use, first connect the mounting plate 110 to the tower body, then align the connecting clip 107 with the mounting block 108 and insert it into the sliding frame 106, then fix the mounting block 108 with the fixing bolts 109, and finally manually operate the rotating ring 104 on the fixing plate 102 to drive the rotating tube 103 to rotate, driving the screws 105 at both ends to extend and retract synchronously, adjusting the length to match the spacing of the tower body connection points. During installation, the connecting mechanism 1 only needs to slide and align and fix the bolts 109, without the need for complex welding or bolt tightening, simplifying the assembly process and improving construction efficiency.

[0023] like Figure 3 As shown, the support mechanism 2 includes a connecting plate 201, which is connected to the fixed frame 101. Reinforcing plates 202 are fixedly connected to both sides of the top of the connecting plate 201. A through hole is opened in the center of the top of the reinforcing plate 202. A rotating rod 203 is rotatably connected in the through hole. A turntable 204 is fixedly connected to one end of the rotating rod 203. A plurality of equidistant through holes are opened on the top of the turntable 204. Limiting bolts 205 are installed in the through holes. The limiting bolts 205 are compatible with the reinforcing plate 202. A fixed tube 206 is fixedly connected to one side of the rotating rod 203. A sliding rod 207 is slidably connected to the inner wall of the fixed tube 206. A through hole is opened on one side of the fixed tube 206. A pin 208 is inserted into the through hole and passes through the sliding rod 207.

[0024] It should be noted that, firstly, the rotating rod 203 is manually operated to rotate to the required angle via the turntable 204, and the position is fixed by the limiting bolt 205 to adapt to the tilt of the tower or the direction of wind load. Then, the sliding rod 207 extends and retracts within the fixed tube 206, and the length is locked by the pin 208 to precisely adjust the position of the support point. Finally, the reinforcing plate 202 transmits the support force to the fixed frame 101, dispersing the tower load and enhancing the lateral stiffness. The support mechanism 2 can be rotated to adjust the angle, which can adapt to the support requirements of different directions of the tower, improve the support flexibility, and also realize the fine adjustment of the support length to further adapt to the spatial position deviation of the tower connection point.

[0025] During use, the mounting plate 110 is first connected to the tower body. Then, the connecting clip 107 is aligned with the mounting block 108 and inserted into the sliding frame 106. Next, the mounting block 108 is fixed with the fixing bolts 109. Finally, the rotating ring 104 on the fixing plate 102 is manually operated to drive the rotating tube 103 to rotate, driving the screws 105 at both ends to extend and retract synchronously, adjusting the length to match the spacing of the tower body connection points. Then, the rotating rod 203 is manually operated to rotate to the required angle via the turntable 204, and the position is fixed using the limiting bolts 205 to adapt to the tower body tilt or wind load direction. Subsequently, the sliding rod 207 extends and retracts within the fixing tube 206, and the length is locked by the pin 208 to precisely adjust the support point position. Finally, the reinforcing plate 202 transmits the support force to the fixing frame 101, dispersing the tower body load and enhancing lateral stiffness. This device can synchronously adjust the extension and retraction length of the screws 105 at both ends, adapting to the connection requirements of tower bodies of different specifications or installation errors, without the need to replace parts, thus improving versatility.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
