Description

Technical Field

[0001] This utility model relates to the field of power towers, specifically a combined support iron component structure for a high-strength, weather-resistant power tower. Background Technology

[0002] The combined support iron component structure of power towers is characterized by the fact that all tower types are spatial truss structures. The members are mainly composed of single equilateral angle steel or combined angle steel. The materials generally used are Q235 (A3F) and Q345 (16Mn). The connection between the members is 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 combination.

[0003] In existing technologies, the combined support of power towers is usually composed of multiple rods, and the crossarm on it also adopts a support structure composed of multiple rods. Since the crossarm needs to install multiple insulators, the flexibility of the support is required. However, most crossarm supports currently use welding or bolt fixing connection methods. This fixed connection method makes it difficult to effectively adjust the spacing of insulators on the crossarm combined support, which cannot meet the usage requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a combined support iron component structure for a high-strength, weather-resistant power tower, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A composite support iron component structure for a high-strength weather-resistant power tower includes a first support and a second support. A first fastener and a second fastener are welded to one end of the first support and the second support at the top and bottom. An inclined support frame is fixedly connected to the lower end of the first support and the second support. One end of the inclined support frame is fixedly installed on one side of the second fastener. An adjustment component for adjusting the spacing between insulators is provided at the upper end of the first support and the second support.

[0006] Preferably, the adjustment component includes a fixed frame plate, the fixed frame plate has a through-hole, the lower end of the fixed frame plate is fixedly connected to one side of the first bracket, an adjustment through hole is formed between the first bracket and the second bracket, and sliding grooves are formed on both sides of the adjustment through hole.

[0007] Preferably, guide blocks are slidably connected inside the adjustment through holes of the first and second brackets, and sliding blocks are fixedly connected to both sides of the guide blocks, with both sliding blocks slidably connected inside the sliding groove.

[0008] Preferably, a fixing block is fixedly connected to the upper end of the guide block, an insulator body is fixedly installed on the upper end of the fixing block, and a connecting plate is fixedly connected to one side of the fixing block.

[0009] Preferably, both ends of the connecting plate are rotatably connected to threaded bolts at the upper part.

[0010] Preferably, one end of each of the two threaded bolts is slidably fitted inside the fixing groove of the fixing plate.

[0011] Preferably, a contact piece is slidably sleeved on the outer side of one end of each of the two threaded bolts, and a fixing nut is tightly attached to one side of each of the two contact pieces. The interior of each of the two fixing nuts is rotatably connected to one end of the outer side of the threaded bolt.

[0012] The beneficial effects of this utility model are: This invention, through the cooperation of the guide block and the sliding groove, allows the insulator body to slide smoothly along the axial direction of the adjustment through hole, realizing the position adjustment of the insulator in the combined support formed by the first and second supports. The operator can easily move the insulator to the target position. The friction between the contact plate and the fixed frame plate firmly locks the threaded bolt in the fixed groove, ensuring that the insulator body remains stable in the adjusted position. This avoids the difficulty in adjusting the spacing of the insulators on the crossarm combined support, and increases the combined support to meet the usage requirements. Attached Figure Description

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 As shown, a combined support iron component structure for a high-strength weather-resistant power tower includes a first support 1 and a second support 2. A first fastener 6 and a second fastener 7 are welded to one end of the first support 1 and the second support 2 at the top and bottom. An inclined support frame 3 is fixedly connected to the lower end of the first support 1 and the second support 2. One end of the inclined support frame 3 is fixedly installed on one side of the second fastener 7. An adjustment component 5 for adjusting the spacing between insulators is provided at the upper end of the first support 1 and the second support 2.

[0017] In specific implementation, the first support 1 and the second support 2 are welded together by the first fastener 6 and the second fastener 7 at the upper and lower ends to form a stable combined support structure. The lower end of the inclined support frame 3 is fixed to the bottom of the support, and the other end is connected to the second fastener 7 to form a triangular support structure. The triangle has stability and can enhance the anti-overturning ability of the bottom of the support. The upper adjustment component 5 is used to adjust the installation spacing of the insulators. In the power system, the insulators need to maintain a suitable distance according to the voltage level and environmental conditions such as icing and wind speed to prevent arc discharge or mechanical collision. The adjustment component 5 can realize flexible adjustment of the spacing through bolts, grooves and other structures to ensure that the insulators can work normally under different working conditions. The combined support is usually made of low alloy high strength steel material, containing alloying elements such as manganese, silicon and vanadium. The yield strength is ≥345MPa and the tensile strength is ≥490MPa. The weather resistance is better than that of ordinary carbon steel. The resistance to atmospheric corrosion and high strength can be improved by adding elements such as copper and phosphorus.

[0018] like Figures 1 to 4As shown, as a technical optimization of this utility model, the adjustment component 5 includes a fixed frame plate 51. A fixed groove 54 is formed through the interior of the fixed frame plate 51. The lower end of the fixed frame plate 51 is fixedly connected to one side of the first bracket 1. An adjustment through hole 53 is formed between the first bracket 1 and the second bracket 2. Sliding grooves 52 are formed inside both sides of the adjustment through hole 53. A guide block 510 is slidably connected inside the adjustment through hole 53 of the first bracket 1 and the second bracket 2. Sliding blocks 511 are fixedly connected to both sides of the guide block 510. Both sliding blocks 511 are slidably connected inside the sliding grooves 52. A fixed block 58 is fixedly connected to the upper end of the guide block 510. An insulator body 4 is fixedly installed on the upper end of the fixed block 58. A connecting plate 59 is fixedly connected to one side of the fixed block 58.

[0019] Furthermore, threaded bolts 57 are rotatably connected to the upper ends of the connecting plate 59. One end of each threaded bolt 57 is slidably fitted inside the fixing groove 54 of the fixing plate 51. A contact piece 56 is slidably fitted to the outer side of one end of each threaded bolt 57. A fixing nut 55 is tightly attached to one side of each contact piece 56. The interior of each fixing nut 55 is rotatably connected to the outer end of each threaded bolt 57.

[0020] In a specific embodiment, the guide block 510 is embedded in the sliding groove 52 through the sliding blocks 511 on both sides, so that the insulator body 4 can slide along the axial direction of the adjustment through hole 53, that is, the direction between the first bracket 1 and the second bracket 2. Manually pushing or pulling the insulator body 4 causes the guide block 510 to slide along the adjustment through hole 53. The sliding block 511 moves synchronously in the sliding groove 52 until the insulator reaches the target position. The connecting plate 59 is connected to the fixing groove 54 of the fixing bracket plate 51 through the threaded bolt 57. When the threaded bolt 57 is not tightened, the contact piece 56 and the fixing nut 55 are in a loose state, and the connecting plate 59 can slide with the guide block 510. When the fixing nut 55 is rotated, the nut is tightened along the threaded bolt 57, pushing the contact piece 56 to press against the surface of the fixing bracket plate 51. The threaded bolt 57 is fixed in the fixing groove 54 by friction, thereby locking the position of the connecting plate 59 and the insulator body 4.

[0021] In use, the guide block 510 is embedded in the sliding groove 52 by the sliding blocks 511 on both sides, so that the insulator body 4 can slide along the axial direction of the adjustment through hole 53, that is, the direction between the first bracket 1 and the second bracket 2. Manually pushing or pulling the insulator body 4 causes the guide block 510 to slide along the adjustment through hole 53. The sliding blocks 511 move synchronously in the sliding groove 52 until the insulator reaches the target position. The connecting plate 59 is connected to the fixing groove 54 of the fixing bracket plate 51 by the threaded bolt 57. When the threaded bolt 57 is not tightened, the contact piece 56 and the fixing nut 55 are in a loose state, and the connecting plate 59 can slide with the guide block 510. When the fixing nut 55 is rotated, the nut is tightened along the threaded bolt 57, pushing the contact piece 56 to press against the surface of the fixing bracket plate 51. The threaded bolt 57 is fixed in the fixing groove 54 by friction, thereby locking the position of the connecting plate 59 and the insulator body 4.
