Description
Technical Field
[0001] This invention relates to the field of tower installation technology, and in particular to a power transmission tower and its installation method. Background Technology
[0002] In the power industry system, transmission lines are the core carriers for cross-regional energy allocation, while transmission towers, as key infrastructure supporting conductors and ground wires, directly determine the safety and economy of power grid operation through their structural stability, ease of installation, and service life. With the accelerated transformation of my country's energy structure, wind power, photovoltaic, and other new energy power plants are mostly distributed in remote mountainous, plateau, or coastal areas, significantly extending transmission distances. Furthermore, the service environment encompasses complex conditions such as high salt spray, strong winds and sandstorms, and large temperature differences, placing higher demands on the structural adaptability, corrosion resistance, and construction efficiency of transmission towers. Currently, transmission line towers can be classified into five main types according to their structural shape, each with differentiated applications based on engineering needs: Goblet-shaped towers, due to their symmetrical triangular conductor arrangement and large insulation gaps, are suitable for 220kV and above high-voltage transmission lines; Cat-head-shaped towers, with their low conductor suspension point and compact tower head size, offer excellent crosswind stability and are often used in multi-circuit transmission scenarios; and U-shaped towers, with their simple structure and low material consumption, are suitable for single-circuit low-voltage transmission lines. Transmission lines are classified into several types: T-shaped towers, which have the ability to suspend conductors on both sides, are often used as angle towers or branch towers; barrel-shaped towers have a cylindrical body, high overall rigidity, and are suitable for large-span transmission projects crossing rivers, canyons, etc. Classified by function, tension towers are used to bear conductor tension and limit the range of line faults; straight-line towers bear vertical and horizontal wind loads on conductors; angle towers adapt to changes in line direction; transposition towers are used to balance the electromagnetic induction of three-phase conductors; terminal towers connect substations and transmission lines; and crossing towers are designed for special scenarios such as crossing railways and highways. Structurally, existing towers generally adopt a space truss structure, with single equilateral angle steel or combined angle steel as the main material. The materials mostly use Q235 (A3F) low-carbon steel or Q345 (16Mn) low-alloy high-strength steel. Q235 steel has low cost and good weldability, making it suitable for tower components with smaller loads; Q345 steel has high yield strength and excellent fatigue resistance, and is mostly used for key load-bearing components such as the main tower body. The tower is connected by coarse bolts, and the load is transferred by the shear force of the bolts. The whole structure is assembled from angle steel, connecting steel plates and bolts. Only the tower feet and other complex stress-bearing components are assembled by welding multiple steel plates together. This structural design gives the tower the advantage of modular transportation, and the hot-dip galvanizing process can achieve corrosion protection, which can reduce the risk of rust in the outdoor environment. However, existing technologies still have significant limitations: First, welded tower legs require on-site welding, which is greatly affected by weather conditions such as wind, rain, and low temperatures, making the welding quality prone to fluctuations. Furthermore, the anti-corrosion layer at the weld seam is easily damaged, becoming a potential source of rust. Second, bolted connections require high-altitude alignment and installation. In field construction, the weight of the components makes alignment difficult, resulting in low installation efficiency. Moreover, after long-term operation, the bolts are prone to loosening due to vibration, requiring frequent maintenance. Therefore, it is urgent to optimize the tower structure design and installation process to solve the problems of low construction efficiency, easy loosening, and high operational difficulty in existing technologies, and to meet the construction needs of transmission lines under complex working conditions. To address the aforementioned problems, this invention proposes a power transmission tower and its installation method. Summary of the Invention
[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a power transmission tower and its installation method, solving problems such as low bolt installation efficiency, easy loosening, and high operational difficulty.
[0004] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a power transmission tower, comprising a tower body, a tower base, and a concrete base. The lower end of the tower body is fixedly connected to the tower base. A four-pronged rod is fixedly connected to the lower surface of the tower base in a rectangular array. A top rod is fixedly connected to the lower surface of the tower base. An X-shaped groove is provided inside the concrete base. Slots are provided at the four ends of the X-shaped groove, and the slots are adapted to the prongs. A first-position slot is provided at the lower end of the prong. An anchoring device is provided inside the concrete base, and the anchoring device includes a longitudinal connecting component and a transverse connecting component.
[0005] Preferably, the concrete base is provided with four rectangular arrayed baffles on its periphery, and the inner wall of the baffles is in contact with the tower base.
[0006] By adopting the above technical solution and setting baffles, it is easier to align the tower base and the concrete base during hoisting, thus making the connection easier.
[0007] Preferably, the longitudinal connecting assembly includes a tension spring, a lower pressure sleeve, a hook, and a first spring. The upper end of the tension spring is fixedly connected to the concrete base, and the lower end of the tension spring is fixedly connected to the lower pressure sleeve. The lower part of the lower pressure sleeve is engaged with the hook. The side surface of the hook is fixedly connected to the first spring. The end of the first spring away from the hook is fixedly connected to the concrete base. The lower part of the lower pressure sleeve is provided with a hook groove that is compatible with the hook. The interior of the concrete base is provided with a movable groove, and the first spring and the hook groove are located in the movable groove.
[0008] By adopting the above technical solution and setting a longitudinal connection component, when the tower base is hoisted and lowered, the top rod is pressed down and inserted into the lower pressure sleeve, and the lower pressure sleeve is lowered accordingly. The hook groove in the lower pressure sleeve is engaged with the hook to complete the longitudinal abutment.
[0009] Preferably, the transverse connection assembly includes a tension rod, a plug, a second spring, and a locking block. The side surface of the lower pressure sleeve is hinged to the tension rod, the end of the tension rod away from the lower pressure sleeve is hinged to the plug, the second spring is located inside the plug, one end of the second spring is fixedly connected to the plug, the end of the second spring away from the plug is fixedly connected to the locking block, and the plug is engaged with the first locking slot.
[0010] By adopting the above technical solution and setting up a transverse connecting component, the action of the lower pressure sleeve pressing down and engaging the concrete base drives the tension rod hinged to the periphery of the lower pressure sleeve to open, and pushes the plug. After the plug slides horizontally into the first slot, it completes the engagement with the cooperation of the second spring and the locking block. In conjunction with the longitudinal connecting component, it completes the anchoring of the tower base and the concrete base, greatly improving the stability and anti-overturning ability of the tower body. At the same time, the installation is simple and convenient, only requiring alignment and insertion of each slot.
[0011] Preferably, the plug is internally rotatably connected to a roller, the lower part of the X-shaped groove is provided with a rolling groove, and the side surface of the roller is in contact with the rolling groove.
[0012] By adopting the above technical solution and setting rollers and grooves, the resistance during the tensioning rod opening process is reduced, and the plug can move along the direction of the groove, making the docking of the plug with the first slot more precise and less prone to deviation.
[0013] Preferably, the upper surface of the tower base is provided with an anti-overturning component, which includes a wind pressure plate and a stop bar. The lower surface of the wind pressure plate is hinged to the tower base, and the upper end of the stop bar is hinged to the wind pressure plate.
[0014] By adopting the above technical solution and setting up anti-overturning components, the wind pressure plate is tilted inward at a certain angle, so that when the horizontal wind blows, the wind pressure plate will be pressed down, thereby causing the tower body to be subjected to a downward drag force. The stronger the wind, the greater the downward pressure, thus preventing the tower body from being blown over in strong winds and greatly improving its anti-overturning ability.
[0015] Preferably, the lower end of the abutment is provided with an adjustment component, which includes a slider, a threaded rod and a threaded sleeve. The lower end of the abutment is hinged to the slider, the inside of the slider is rotatably connected to the threaded rod, the end of the threaded rod away from the slider is threadedly connected to the threaded sleeve, and the end of the threaded sleeve away from the threaded rod is fixedly connected to the tower base.
[0016] An adjustment component is installed, which uses a rotating threaded rod to extend or retract within a threaded sleeve, thereby pushing a stop rod and changing the angle of the wind pressure plate. This allows the tower's anti-overturning performance to adapt to different wind conditions.
[0017] Preferably, the side surface of the threaded rod is threaded with a nut, and the upper surface of the tower base is provided with a cross-shaped groove, the inner wall of which fits against the slider.
[0018] By adopting the above technical solution, a nut is set to limit the threaded rod and threaded sleeve, preventing loosening that could cause changes in the angle of the air pressure plate. Furthermore, the sliding trajectory of the slider is limited by the cross-shaped groove, making its sliding process more stable.
[0019] A method for installing a power transmission tower includes the following steps: S1. Preliminary preparation and basic inspection: Clean the construction site around the concrete base to ensure that the site is flat and free of obstacles, and check whether the X-shaped groove, slot, movable groove and roller groove of the concrete base are intact. At the same time, confirm whether the position of the four baffles is compatible with the tower base to ensure the accuracy of subsequent docking. S2. Tower body and tower base pre-assembly: Fix the lower end of the tower body to the tower base on the ground to form a pre-assembly unit. Check the insert rod on the lower surface of the tower base to ensure that the No. 1 slot is undamaged and the top rod is secure. At the same time, pre-assemble the anti-overturning components on the upper surface of the tower base. S3. Pre-assembled unit hoisting and docking: Use hoisting equipment to lift the pre-assembled unit consisting of the tower body and tower base, and slowly lower it to the top of the concrete base. Guide the tower base to position it through the baffles around the concrete base, so that the insertion rod of the tower base is aligned and initially inserted into the slot of the concrete base, while the lower end of the top rod contacts the lower pressure sleeve of the anchoring device. S4. Automatic locking of anchoring device: Continue to lower the pre-installed unit, press down the top rod and insert it into the lower pressure sleeve, causing the lower pressure sleeve to descend against the tension of the tension spring. When the hook groove of the lower pressure sleeve moves to the position of the hook in the movable groove, the first spring pulls the hook into the hook groove to complete the longitudinal anchoring. At the same time, as the lower pressure sleeve descends, the tension rod hinged on its periphery opens outwards, pushing the plug to slide horizontally and insert into the first slot of the plug rod. After the plug is inserted, the second spring inside releases its elasticity, pushing the block outwards and pressing against the inner wall of the first slot to form a lateral limit, completing the lateral anchoring, and finally achieving a firm connection between the tower base and the concrete base. S5. Anti-overturning component angle adjustment: According to the normal wind conditions of the installation site, rotate the threaded rod to extend or retract the threaded rod in the threaded sleeve, push the slider to slide along the cross-shaped groove, and the slider drives the abutment to adjust the angle, thereby tilting the wind pressure plate to the preset angle. The greater the wind force, the greater the inward tilt angle of the wind pressure plate. After the angle adjustment is completed, tighten the nut on the side surface of the threaded rod to limit the threaded rod and the threaded sleeve. S6. Overall Inspection and Acceptance: Check the verticality of the tower body, confirm whether the insertion rod and slot, plug and No. 1 slot are firmly connected, check whether the angle of the wind pressure plate meets the design requirements, and whether the nuts are tightened; finally, test the pull-out force of the anchoring device and the stability of the anti-overturning components to ensure that the overall structure meets the installation standards of power transmission towers.
[0020] (III) Beneficial Effects In summary, the present invention has at least one of the following beneficial technical effects:
[0021] 1. A power transmission tower and its installation method, which integrates a linkage-type automatic anchoring device by combining the tension spring, lower pressure sleeve, and hook of the longitudinal connecting component with the tension rod, plug, and locking block of the transverse connecting component. The lower pressure sleeve is driven by the self-weight of the tower base during hoisting and lowering to overcome the tension of the tension spring and simultaneously trigger longitudinal anchoring and transverse limiting: In the longitudinal direction, the first spring pushes the hook into the hook groove of the lower pressure sleeve to achieve longitudinal fixation; in the transverse direction, the lower pressure sleeve drives the tension rod to open and pushes the plug into the first locking groove of the plug rod, while the second spring tightens the locking block to complete transverse locking. This design eliminates the need for traditional high-altitude bolt alignment and tightening, solving the pain points of traditional bolts being prone to loosening due to vibration and requiring frequent maintenance, significantly shortening the anchoring operation time, and realizing an innovative mode of automatic anchoring during hoisting and lowering, greatly improving construction efficiency and anchoring reliability in complex environments.
[0022] 2. A power transmission tower and its installation method, which combines the wind pressure plate and the abutment of the anti-overturning component with the slider, threaded rod and threaded sleeve of the adjusting component, breaks through the limitation of the fixed anti-overturning performance of traditional towers. By utilizing the extension and retraction of the threaded rod in the threaded sleeve, the slider is driven to slide along the cross-shaped groove, which drives the abutment to adjust the inward tilt angle of the wind pressure plate. The greater the wind force at the installation site, the greater the inward tilt angle of the wind pressure plate can be increased, so that a stronger downward drag force is generated when the horizontal wind is acting, forming a dynamic protection of "the stronger the wind, the greater the anti-overturning force". The nut lock ensures the angle is stable. Compared with the traditional structure, the ability to resist strong winds is improved, and precise protection is achieved under different wind field conditions. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The present invention will be further described in detail below.
[0026] Example: A power transmission tower and its installation method, referring to... Figure 1-5 The system includes a tower body 1, a tower base 2, and a concrete base 3. The lower end of the tower body 1 is fixedly connected to the tower base 2. Four insertion rods 4 are fixedly connected to the lower surface of the tower base 2 in a rectangular array. A top rod 5 is fixedly connected to the lower surface of the tower base 2. An X-shaped groove 6 is provided inside the concrete base 3. Each of the four ends of the X-shaped groove 6 is provided with a slot 7, which is adapted to the insertion rod 4. A first slot 8 is provided at the lower end of the insertion rod 4. Four rectangular array baffles 9 are provided around the perimeter of the concrete base 3. The inner wall of the baffles 9 fits against the tower base 2. By setting the baffles 9, it is convenient to align the tower base 2 and the concrete base 3 during hoisting, thus making it easier to connect.
[0027] An anchoring device is installed inside the concrete base 3. The anchoring device includes a longitudinal connecting component and a transverse connecting component. The longitudinal connecting component includes a tension spring 10, a lower pressure sleeve 11, a hook 12, and a first spring 13. The upper end of the tension spring 10 is fixedly connected to the concrete base 3, and the lower end of the tension spring 10 is fixedly connected to the lower pressure sleeve 11. The lower part of the lower pressure sleeve 11 is engaged with the hook 12, and the side surface of the hook 12 is fixedly connected to the first spring 13. The end of the first spring 13 away from the hook 12 is fixedly connected to the concrete base 3. The lower part of the lower pressure sleeve 11 is provided with a hook groove 14, which is adapted to the hook 12. The concrete base 3 is provided with a movable groove 15, in which the first spring 13 and the hook groove 14 are located. By setting the longitudinal connecting component, when the tower base 2 is hoisted and lowered, the top rod 5 is pressed down and inserted into the lower pressure sleeve 11. The lower pressure sleeve 11 then lowers, and the hook groove 14 in the lower pressure sleeve 11 engages with the hook 12 to complete the longitudinal engagement. The connecting assembly includes a tension rod 16, a plug 17, a second spring 18, and a locking block 28. The side surface of the lower pressure sleeve 11 is hinged to the tension rod 16. The end of the tension rod 16 away from the lower pressure sleeve 11 is hinged to the plug 17. The second spring 18 is located inside the plug 17. One end of the second spring 18 is fixedly connected to the plug 17, and the end of the second spring 18 away from the plug 17 is fixedly connected to the locking block 28. The plug 17 is engaged with the first locking slot 8. By setting up the transverse connecting assembly, the action of the lower pressure sleeve 11 pressing down and engaging the concrete base 3 drives the tension rod 16, which is hinged to the periphery of the lower pressure sleeve 11, to open and push the plug 17. After the plug 17 slides horizontally into the first locking slot 8, the engagement is completed by the cooperation of the second spring 18 and the locking block 28. In conjunction with the longitudinal connecting assembly, the anchoring of the tower base 2 and the concrete base 3 is completed, which greatly improves the stability and anti-overturning ability of the tower body 1. At the same time, the installation is simple and convenient, and it is only necessary to align and insert the plug into each slot.
[0028] The plug 17 is internally connected to a roller 19, and the lower part of the X-shaped groove 6 is provided with a roller groove 20. The side surface of the roller 19 fits against the roller groove 20. By setting the roller 19 and the roller groove 20, the resistance during the tensioning rod 16 opening is reduced, and the plug 17 can move along the direction of the roller groove 20, making the docking of the plug 17 with the first slot 8 more precise and less prone to deviation.
[0029] The upper surface of the tower base 2 is equipped with an anti-overturning component, which includes a wind pressure plate 21 and a stop rod 22. The lower surface of the wind pressure plate 21 is hinged to the tower base 2, and the upper end of the stop rod 22 is hinged to the wind pressure plate 21. By setting up the anti-overturning component, the wind pressure plate 21 is tilted inward at a certain angle, so that when a horizontal wind blows, the wind pressure plate 21 will be pressed down, thereby causing the tower body 1 to be subjected to a downward drag force. The stronger the wind, the greater the downward pressure, thus preventing the tower body 1 from being blown over in strong winds and greatly improving its anti-overturning ability. The lower end of the stop rod 22 is equipped with an adjustment component, which includes a slider, a threaded rod, and a threaded sleeve. The lower end of the stop rod 22 is hinged to the slider, and the inside of the slider is rotatably connected to the threaded rod. The threaded rod is away from the slider. One end of the slider is threadedly connected to the threaded sleeve, and the end of the threaded sleeve away from the threaded rod is fixedly connected to the tower base 2. By setting an adjustment component, the threaded rod is rotated to extend or retract in the threaded sleeve, thereby pushing the abutment rod 22 and changing the angle of the wind pressure plate 21. This allows the anti-overturning performance of the tower body 1 to adapt to different wind conditions. A nut is threadedly connected to the side surface of the threaded rod, and a cross-shaped groove is provided on the upper surface of the tower base 2. The inner wall of the cross-shaped groove fits against the slider. By setting the nut, the threaded rod and the threaded sleeve are limited to prevent loosening that could cause a change in the angle of the wind pressure plate 21. Furthermore, the sliding trajectory of the slider is limited by the cross-shaped groove, making its sliding process more stable.
[0030] A method for installing a power transmission tower includes the following steps: S1. Preliminary preparation and basic inspection: Clean the construction site around the concrete base 3 to ensure that the site is flat and free of obstacles, and check whether the X-shaped groove 6, slot 7, movable groove 15 and roller groove 20 of the concrete base 3 are intact. At the same time, confirm whether the positions of the four baffles 9 are compatible with the tower base 2 to ensure the subsequent docking accuracy. S2. Pre-assembly of tower body and tower base: On the ground, fix the lower end of tower body 1 to tower base 2 to form a pre-assembly unit. Check the insertion rod 4 on the lower surface of tower base 2 to ensure that the first slot 8 is undamaged and the top rod 5 is secure. At the same time, pre-assemble the anti-overturning components on the upper surface of tower base 2. S3. Pre-assembled unit hoisting and docking: Use hoisting equipment to lift the pre-assembled unit consisting of tower body 1 and tower base 2, and slowly lower it to the concrete base 3. Guide the tower base 2 to position through the baffle 9 on the periphery of the concrete base 3, so that the insertion rod 4 of the tower base 2 is aligned and initially inserted into the slot 7 of the concrete base 3, while the lower end of the top rod 5 contacts the lower pressure sleeve 11 of the anchoring device. S4. Automatic locking of anchoring device: Continue to lower the pre-installed unit, the top rod 5 presses down and inserts into the lowering sleeve 11, driving the lowering sleeve 11 to descend against the tension of the tension spring 10. When the hook groove 14 of the lowering sleeve 11 moves to the position of the hook 12 in the movable groove 15, the first spring 13 pulls the hook 12 into the hook groove 14, completing the longitudinal anchoring. At the same time, as the lowering sleeve 11 descends, the tension rod 16 hinged on its periphery opens outwards, pushing the plug 17 to slide horizontally and insert into the first slot 8 of the plug rod 4. After the plug 17 is inserted, the second spring 18 inside it releases its elasticity, pushing the locking block 28 outwards and pressing against the inner wall of the first slot 8, forming a lateral limit, completing the lateral anchoring, and finally achieving a firm connection between the tower base and the concrete base. S5. Anti-overturning component angle adjustment: According to the normal wind conditions of the installation site, rotate the threaded rod to extend or retract the threaded rod in the threaded sleeve, push the slider to slide along the cross-shaped groove, and the slider drives the abutment rod 22 to adjust the angle, thereby tilting the wind pressure plate 21 to the preset angle. The greater the wind force, the greater the inward tilt angle of the wind pressure plate. After the angle adjustment is completed, tighten the nut on the side surface of the threaded rod to limit the threaded rod and the threaded sleeve. S6. Overall Inspection and Acceptance: Check the verticality of tower body 1, confirm whether the insertion rod 4 and slot 7, plug 17 and slot 8 are firmly connected, check whether the angle of wind pressure plate 21 meets the design requirements, and whether the nuts are tightened; finally, test the pull-out force of the anchoring device and the stability of the anti-overturning components to ensure that the overall structure meets the installation standards of power transmission towers.

Guide the tower base (2) to position through the baffle (9) around the concrete base (3), so that the insertion rod (4) of the tower base (2) is aligned and initially inserted into the slot (7) of the concrete base (3), while the lower end of the top rod (5) contacts the lower pressure sleeve (11) of the anchoring device. S4. Automatic locking of anchoring device: Continue to lower the pre-installed unit, the top rod (5) presses down and inserts into the lower pressure sleeve (11), driving the lower pressure sleeve (11) to overcome the tension of the tension spring (10) and descend. When the hook groove (14) of the lower pressure sleeve (11) moves to the position of the hook (12) in the movable groove (15), the first spring (13) pulls the hook (12) into the hook groove (14) to complete the longitudinal anchoring. At the same time, as the lower pressure sleeve (11) descends, the tension rod (16) hinged on its periphery opens outwards, pushing the plug (17) to slide horizontally and insert into the first slot (8) of the plug rod (4). After the plug (17) is inserted, the second spring (18) inside it releases the elastic force, pushing the card block (28) outwards and pressing against the inner wall of the first slot (8) to form a lateral limit, completing the lateral anchoring, and finally achieving a firm connection between the tower base and the concrete base. S5. Anti-overturning component angle adjustment: According to the normal wind conditions of the installation site, rotate the threaded rod to make the threaded rod extend or retract in the threaded sleeve, push the slider to slide along the cross-shaped groove, and the slider drives the abutment rod (22) to adjust the angle, thereby making the wind pressure plate (21) tilt to the preset angle. The greater the wind force, the greater the inclination angle of the wind pressure plate. After the angle adjustment is completed, tighten the nut on the side surface of the threaded rod to limit the threaded rod and the threaded sleeve. S6. Overall inspection and acceptance: Check the verticality of the tower body (1), confirm whether the plug rod (4) and slot (7), plug (17) and No. 1 slot (8) are firmly connected, check whether the angle of the wind pressure plate (21) meets the design requirements, and whether the nut is tightened; finally, test the pull-out force of the anchoring device and the stability of the anti-overturning component to ensure that the overall structure meets the installation standards of power transmission tower.
