Segmented height-adjustable angle steel power transmission tower

Abstract

This application relates to the field of transmission tower technology, specifically disclosing a segmented adjustable-height angle steel transmission tower, including a concrete foundation. The concrete foundation has an internal mounting groove, inside which four threaded cylinders are fixedly installed. Each threaded cylinder has a threaded fastener connected internally. The outer surfaces of the four fasteners are threadedly connected to a lower base flange, and the outer surface of the lower base flange is fixedly connected to a lower base plate. Through the cooperation of the lower and upper angle steel frames, combined with an adjustment mechanism, the relative height of the two steel frames can be flexibly adjusted. This allows for adaptation to different terrain differences or temporary height requirements at construction sites without the need for custom-made tower bodies. It solves the problem of integrated structures using integral welding or bolt fixing, which cannot adjust the height according to the actual terrain of the construction site. Furthermore, if different height scenarios are required, tower bodies of different specifications must be custom-made, leading to increased construction costs and extended construction periods.

Description

Technical Field

[0001] This application relates to the field of transmission tower technology, and in particular to segmented adjustable height angle steel transmission towers. Background Technology

[0002] Angle steel transmission towers are supporting structures used for power transmission lines. They are constructed primarily of angle steel, connecting steel plates, and bolts. Based on their application, they can be categorized into tension towers, straight-line towers, angle towers, transposition towers, terminal towers, and crossing towers. They possess advantages such as high strength and good stability, and can withstand large loads. However, existing angle steel transmission towers are mostly integral welded or bolted structures, with the tower height fixed before leaving the factory. This makes it impossible to adjust the height according to the actual terrain or temporary needs of the construction site. If different height requirements are needed, towers of different specifications must be custom-made, leading to increased construction costs and extended construction periods. Therefore, we propose segmented adjustable-height angle steel transmission towers to solve these problems. Utility Model Content

[0003] This application provides segmented adjustable height angle steel transmission towers, which can solve the problem of not being able to adjust the height according to the actual terrain of the construction site.

[0004] This application provides a segmented adjustable height angle steel transmission tower, including a concrete foundation. The concrete foundation has an installation groove inside, and four threaded cylinders are fixedly installed inside the installation groove. Each threaded cylinder is threadedly connected to a fixing component inside. The outer surfaces of the four fixing components are threadedly connected to a lower base flange. A lower base plate is fixedly connected to the outer surface of the lower base flange. A lower angle steel frame is fixedly connected to the upper surface of the lower base plate. An upper angle steel frame is provided above the lower angle steel frame. Four adjustment mechanisms are installed on the outer surfaces of the lower angle steel frame and the upper angle steel frame.

[0005] Furthermore, the upper surface of the lower angle steel frame is connected to a middle plate by bolts and threads, and the upper surface of the upper angle steel frame is connected to a top plate by bolts and threads.

[0006] Furthermore, a support frame is fixedly connected to the upper surface of the top plate, and a plurality of insulator mounting holes are opened on the outer surface of the support frame.

[0007] Furthermore, the adjustment mechanism includes a limiting plate, a connecting sleeve, and several adjustment holes, with several limiting holes provided on the outer surface of the connecting sleeve.

[0008] Furthermore, one of the limiting holes is internally threaded with a limiting screw, one end of which passes through the adjusting hole and extends to the outside of the connecting sleeve.

[0009] Furthermore, the outer surface of the limiting screw is threaded with an anti-loosening nut, and the outer surface of the limiting screw is adapted to the interior of the adjusting hole.

[0010] Furthermore, the bottom surface of the concrete foundation is equipped with several reinforcing rib frames, and the outer surface of the lower base flange is adapted to the interior of the mounting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The technical solution provided in this application has at least the following technical effects or advantages: By combining the lower and upper corner steel frames with the adjustment mechanism, the relative height of the two steel frames can be flexibly adjusted. This eliminates the need for custom-made tower bodies to adapt to different terrain differences or temporary height requirements at construction sites. It solves the problem that integrated structures that are welded or bolted together cannot adjust the height according to the actual terrain of the construction site. If different height scenarios are required, tower bodies of different specifications need to be customized, which leads to increased construction costs and extended construction periods.

[0013] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0014] Example 1 Please see Figure 1-4In this utility model, the segmented adjustable height angle steel transmission tower includes a concrete foundation 1. An installation groove 2 is provided inside the concrete foundation 1. Four threaded cylinders 3 are fixedly installed inside the installation groove 2. Each threaded cylinder 3 is threadedly connected to a fixing component 4. The outer surfaces of the four fixing components 4 are threadedly connected to a lower base flange 5. A lower base plate 6 is fixedly connected to the outer surface of the lower base flange 5. A lower angle steel frame 7 is fixedly connected to the upper surface of the lower base plate 6. An upper angle steel frame 8 is provided above the lower angle steel frame 7. The outer surfaces of the lower angle steel frame 7 and the upper angle steel frame 8 are jointly installed. There are four adjustment mechanisms 9. Several reinforcing rib frames 14 are installed on the bottom surface of the concrete foundation 1. The outer surface of the lower base flange 5 is adapted to the inside of the mounting groove 2. The threaded cylinder 3 enables the fastener to stably connect the lower base flange 5 and the concrete foundation 1 through threaded engagement, thereby strengthening the bottom connection strength. The reinforcing rib frames 14 enhance the structural strength and deformation resistance of the concrete foundation 1 itself, preventing the foundation from cracking due to long-term load-bearing or ground settlement, and further improving stability. The insulator mounting holes 13 are used to fix the insulators, enabling the insulators to be installed precisely according to the requirements of the transmission line.

[0015] Example 2 The upper surface of the lower angle steel frame 7 is connected to the middle plate 10 by bolts and threads. The upper surface of the upper angle steel frame 8 is connected to the top plate 11 by bolts and threads. The upper surface of the top plate 11 is fixedly connected to the support frame 12. The outer surface of the support frame 12 is provided with several insulator mounting holes 13. The adjustment mechanism 9 includes a limiting plate 91, a connecting sleeve 92 and several adjustment holes 93. The outer surface of the connecting sleeve 92 is provided with several limiting holes 96. The limiting plate 91 restricts the movement range of the connecting sleeve 92 to prevent the upper angle steel frame 8 from moving excessively relative to the lower angle steel frame 7 and falling off, thus ensuring structural safety during the adjustment process.

[0016] One of the limiting holes 96 has a limiting screw 94 connected to its internal thread. One end of the limiting screw 94 passes through the adjusting hole 93 and extends to the outside of the connecting sleeve 92. The outer surface of the limiting screw 94 is threaded with an anti-loosening nut 95. The outer surface of the limiting screw 94 is adapted to the inside of the adjusting hole 93. The cooperation between the limiting screw 94 and the anti-loosening nut 95 can fix the lower angle steel frame 7 and the upper angle steel frame 8.

[0017] The working principle of this application is: First, the concrete foundation 1 and the reinforcing frame 14 on the bottom surface are fixed together to the construction ground. The reinforcing frame 14 can enhance the connection strength between the foundation and the ground and prevent the tower from tilting. The installation groove 2 inside the concrete foundation 1 is equipped with four threaded cylinders 3. The lower base flange 5 is threadedly connected to the threaded cylinders 3 through the fastener 4, so that the lower base flange 5 is accurately embedded into the installation groove 2, completing the bottom fixing of the lower base plate 6 and the lower corner steel frame 7. Then, the connecting sleeve 92 of the adjusting mechanism 9 is fitted onto the lower corner steel frame 7 and positioned accordingly. Above the limiting plate 91, the upper angle steel frame 8 is then placed inside the connecting sleeve 92. According to the required height, the upper angle steel frame 8 is moved up and down so that the limiting hole 96 on the connecting sleeve 92 is aligned with the adjusting hole 93 at different positions on the steel frame. When the limiting hole 96 is aligned with the adjusting hole 93, the limiting screw 94 is passed through the aligned limiting hole 96 and adjusting hole 93 and extended to the outside of the connecting sleeve 92. Then, the limiting screw 94 is threadedly connected to the anti-loosening nut 95 and tightened to fix the connecting sleeve 92 and the steel frame.
