Description
Technical Field
[0001] This invention relates to the field of transmission towers, and more specifically to a force adjustment device for angle steel poles of transmission towers. Background Technology
[0002] Transmission towers serve as the support points for overhead lines. A single-circuit transmission tower supports one circuit, while a double-circuit tower supports two circuits. Transmission towers are tall structures, highly sensitive to tilting deformation and requiring strict control over uneven ground settlement. Common foundation structures for transmission towers include independent foundations, spread foundations, and pile foundations. The primary structural form for transmission towers is steel. Conventional transmission tower and foundation structures are ill-suited to adapt to surface movement and deformation in coal mine goaf areas, potentially causing tower tilting or even overturning.
[0003] Transmission towers operate in harsh environments and their structures are not simple. While the tower structure is safe when the stress is less than the design strength, after prolonged exposure to wind, rain, and sun, local components of the crossarm angle steel rods of transmission towers often experience cross-sectional corrosion. This causes the stress in the components to reach the material's yield strength, resulting in yield failure, structural strength failure, and a decrease in load-bearing capacity, posing a significant safety hazard. Therefore, it is necessary to design a stress adjustment device for the angle steel rods of transmission towers. Summary of the Invention
[0004] The purpose of this invention is to provide a force adjustment device for angle steel poles used in transmission towers.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A force adjustment device for angle steel rods of transmission towers is provided, comprising a transmission tower, a rotating mechanism, a supporting mechanism, a stress relief mechanism, and a wind guiding mechanism. The rotating mechanism is located at the top between two horizontal arms on one side of the transmission tower. The rotating mechanism includes an upper support plate, a mounting box, and two sets of adjusting components. The upper support plate is fixedly installed at the bottom of the horizontal arm of the transmission tower. The mounting box is fixedly installed at one end of the horizontal arm of the transmission tower and located beside the upper support plate. The two sets of adjusting components are symmetrically and fixedly installed at the bottom of the upper support plate, and the two sets of adjusting components are meshed together. The supporting mechanism includes a side plate and a sliding component. The side plate is fixedly installed on the side of the transmission tower, and the sliding component is fixedly installed on the side plate and hinged to the two sets of adjusting components. The stress relief mechanism includes a pressure-distributing component and a push-slide component. The push-slide component is fixedly installed at the bottom of one side of the side plate, and the pressure-distributing component is fixedly installed on the sliding component and hinged to the push-slide component. The wind guiding mechanism includes two sets of drag-reducing components, which are symmetrically and fixedly installed at both ends of the push-slide component.
[0007] Furthermore, each set of adjustment components includes a mounting block, a bearing, a first slide rail, a slide seat, a shaft seat, a screw, a mounting plate, and a bevel gear. The mounting block is fixedly installed on one side of the top of the side plate. Two wind deflectors are symmetrically and fixedly installed on both sides of the side plate. The bearing is fixedly installed in the middle of one side of the mounting block. The first slide rail is fixedly installed at the bottom of the upper support plate. The slide seat is slidably and limitedly installed on the first slide rail. The mounting plate is vertically fixedly installed in the mounting box. The shaft seat is fixedly installed in the mounting box and located next to the mounting plate.
[0008] Furthermore, one end of the screw is fixedly mounted on the inner ring of the bearing, and the other end of the screw passes through the mounting box and is rotatably connected to the shaft seat. The bevel gear is fixedly mounted on the screw and fits against the mounting plate. The two bevel gears in the two sets of adjustment components are meshed at a 120-degree angle. An adjustment handle is provided on the side of the mounting box, and the adjustment handle is fixedly mounted on the end of the corresponding screw.
[0009] Furthermore, the sliding assembly includes two second slide rails, two limiting rods, two sliders, and two support rods. The two second slide rails are symmetrically and fixedly disposed on the side of the side plate. The two limiting rods are symmetrically and fixedly disposed at both ends of the two second slide rails. The two sliders are symmetrically and slidably disposed on the corresponding two second slide rails. One end of each of the two support rods is hinged to the outside of the corresponding two slide blocks, and the other end of each support rod is fixedly connected to the two sliders.
[0010] Furthermore, the push-slide assembly includes a base rod, a third slide rail, two force-bearing blocks, two stop plates, two slide tables, and two return springs. The base rod is fixedly mounted horizontally at the bottom of the side plate. The third slide rail is fixedly mounted on one side of the base rod. The two slide tables are slidably mounted on the third slide rail. The two stop plates are symmetrically mounted and fixedly mounted on both sides of the base rod.
[0011] Furthermore, the two force-bearing blocks are symmetrically arranged at both ends of the third slide rail, and the two force-bearing blocks are limited and slidably arranged in the two stop plates. The two reset springs are symmetrically welded between the corresponding force-bearing blocks and the slide table. A middle partition block is fixedly provided in the middle of the third slide rail.
[0012] Furthermore, the pressure-dividing assembly includes a lower push rod and two lower pressure rods. The lower push rod is fixedly mounted horizontally at the bottom of the two sliders. The two lower pressure rods are symmetrically mounted at the bottom of the lower push rod, and one end of each lower pressure rod is hinged to the lower push rod. The other end of each lower pressure rod is hinged to the side of the corresponding two slides.
[0013] Furthermore, each set of drag-reducing components includes a connecting plate, a limiting plate, a short rack, a first gear, a second gear, a connecting column, a fixing rod, and a guide plate. The connecting plate is fixedly mounted horizontally on the end of the corresponding drag-reducing plate. One end of the short rack is fixedly mounted on one side of the corresponding force-bearing block. The first gear is rotatably mounted on the connecting plate and meshes with the short rack. The second gear is meshed on the side of the first gear.
[0014] Furthermore, one end of the connecting column is rotatably mounted on the connecting plate, and the connecting column is fixedly connected to the second gear. The limiting plate is fixedly mounted on one side of the connecting plate, and an clearance opening is provided on one side of the limiting plate. The fixing rod is fixedly mounted on the other end of the connecting column, and the air guide plate is fixedly connected to one side of the fixing rod.
[0015] The beneficial effects of this invention are:
[0016] 1. When the cross-section of the angle steel member of the transmission tower's crossarm corrodes, the local structural strength of the angle steel member fails, posing a safety hazard. Therefore, it is necessary to adjust the support position to the corroded area to strengthen its load-bearing capacity. By rotating the adjustment handle, the slide block is indirectly driven to slide on the first slide rail, causing the slide block to move the top of the two support rods. The other end of the support rod drives the slider to move downward along the second slide rail. The slider drives the lower push rod downward, and at the same time, it also causes the two lower pressure rods to move outward in a V-shape. By compressing the two return springs corresponding to the two slides, the vertical load on the crossarm of the transmission tower is cleverly converted into two lateral components. This can greatly reduce the load on the crossarm and extend its service life. At the same time, the two return springs also play a buffering role.
[0017] 2. When the two return springs are compressed and deformed, the return springs will drive the force block to slide within the two stop plates. The two stop plates limit the two force blocks while ensuring that the return springs will not bend when compressed. The force block drives the short rack to move outward. The short rack drives the first gear to rotate clockwise and indirectly drives the second gear to rotate counterclockwise. This causes the second gear to drive the air guide plate to rotate along one side through the connecting column and the fixed rod. The two adjacent air guide plates form a V-shape. When airflow comes, it can be guided from both sides of the two air guide plates. Combined with the cone-shaped wind baffles on both sides of the side plate, the wind resistance is greatly enhanced.
[0018] This invention uses a rotating adjustment handle to adjust the position of the rusted support of the angle steel rod of the transmission tower crossarm. At the same time, it converts the vertical load on the crossarm into two lateral components, enhances wind resistance, and is quick, safe and efficient, thereby improving the actual application strength of the transmission tower crossarm.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0033] This invention provides a technical solution:
[0034] Reference Figures 1 to 3 The diagram illustrates a force adjustment device for angle steel poles of a transmission tower, comprising a transmission tower 1, a rotating mechanism 2, a supporting mechanism 3, a stress-relieving mechanism 4, and a wind-guiding mechanism 5. The rotating mechanism 2 is located at the top between two horizontal arms on one side of the transmission tower 1. The rotating mechanism 2 includes an upper support plate 20, a mounting box 21, and two sets of adjusting components 22. The upper support plate 20 is fixedly installed at the bottom of the horizontal arm of the transmission tower 1. The mounting box 21 is fixedly installed at one end of the horizontal arm of the transmission tower 1 and located beside the upper support plate 20. The two sets of adjusting components 22 are symmetrically and fixedly installed at the bottom of the upper support plate 20, and the two sets of adjusting components 22 are meshed together, providing support. Mechanism 3 includes a side plate 30 and a sliding assembly 31. The side plate 30 is fixedly installed on the side of the transmission tower 1, and the sliding assembly 31 is fixedly installed on the side plate 30. The sliding assembly 31 is hinged to two sets of adjusting assemblies 22. The pressure relief mechanism 4 includes a pressure-distributing assembly 40 and a push-slide assembly 41. The push-slide assembly 41 is fixedly installed on the bottom of one side of the side plate 30, and the pressure-distributing assembly 40 is fixedly installed on the sliding assembly 31. The pressure-distributing assembly 40 is hinged to the push-slide assembly 41. The air guiding mechanism 5 includes two sets of drag-reducing assemblies 50. The two sets of drag-reducing assemblies 50 are symmetrically installed and fixed at both ends of the push-slide assembly 41.
[0035] Reference Figures 4 to 6Each set of adjustment components 22 shown includes a mounting block 220, a bearing 221, a first slide rail 222, a slide block 223, a shaft seat 224, a screw 225, a mounting plate 226, and a bevel gear 227. The mounting block 220 provides a fixed mounting carrier for the bearing 221, and the shaft seat 224 provides a limiting rotation carrier for the screw 225. The mounting block 220 is fixedly installed on one side of the top of the side plate 30. Two wind deflectors 300 are symmetrically and fixedly installed on both sides of the side plate 30. The wind deflectors 300 are for protecting the inner... The first slide rail 222 and screw 225 of the part are protected from sun exposure, wind and rain. The bearing 221 is fixedly installed in the middle of one side of the mounting block 220. The first slide rail 222 is fixedly installed at the bottom of the upper support plate 20. The slide block 223 is limited and slidably installed on the first slide rail 222. The mounting plate 226 is vertically fixed in the mounting box 21. The bearing seat 224 is fixedly installed in the mounting box 21 and located next to the mounting plate 226. One end of the screw 225 is fixedly installed in the inner ring of the bearing 221. The other end of rod 225 passes through mounting box 21 and is rotatably connected to bearing 224. Bevel gear 227 is fixedly mounted on screw 225 and fitted against mounting plate 226. The two bevel gears 227 in the two sets of adjusting components 22 are meshed at a 120-degree angle. This 120-degree meshing allows only one screw 225 to rotate while the other screw 225 rotates synchronously, and also provides a conical mounting position for the two wind deflectors 300. Adjustment is provided on the side of mounting box 21. The adjustment handle 228 is fixedly installed at the end of the corresponding screw 225. When the adjustment handle 228 drives the corresponding screw 225 to rotate, the screw 225 drives the bevel gear 227 on it to rotate. The two bevel gears 227 are meshed, so the two screws 225 rotate synchronously. The two screws 225 respectively drive the corresponding two slide blocks 223 to slide on the two first slide rails 222, so that the two slide blocks 223 respectively drive the top ends of the two support rods 313 to move.
[0036] Reference Figure 7The sliding assembly 31 shown includes two second slide rails 310, two limiting rods 311, two sliders 312, and two support rods 313. The two limiting rods 311 limit the movement of the two sliders 312. The two second slide rails 310 provide a limiting sliding carrier for the two sliders 312. The two support rods 313 support the cross arm. The two second slide rails 310 are symmetrically and fixedly arranged on the side of the side plate 30. The two limiting rods 311 are symmetrically and fixedly arranged at both ends of the two second slide rails 310. The two sliders 312 are symmetrically and slidably arranged on the corresponding two second slide rails 310. One end of the two support rods 313 is respectively hinged to the outside of the corresponding two slide blocks 223, and the other end of the two support rods 313 is respectively fixedly connected to the two sliders 312. When the top of the two support rods 313 moves, the other end of the two support rods 313 drives the two sliders 312 to move downward along the two second slide rails 310. At this time, the two sliders 312 drive the lower push rod 400 to move downward.
[0037] Reference Figure 7 and Figure 8 The pressure-dividing assembly 40 shown includes a lower push rod 400 and two lower pressure rods 401. The lower push rod 400 is fixedly mounted horizontally at the bottom of the two sliders 312. The two lower pressure rods 401 are symmetrically mounted at the bottom of the lower push rod 400, and one end of each lower pressure rod 401 is hinged to the lower push rod 400. The other end of each lower pressure rod 401 is hinged to the side of the corresponding two slides 414. When the lower push rod 400 moves downward, it causes the two lower pressure rods 401 at the bottom to move outward in a V-shape, indirectly compressing the two horizontally mounted return springs at the bottom. This converts the vertical load on the cross arm into two lateral forces, greatly reducing the load on the cross arm of the transmission tower 1.
[0038] The push-slide assembly 41 located at the bottom of the pressure dividing assembly 40 includes a base rod 410, a third slide rail 411, two force-bearing blocks 412, two stop plates 413, two slide tables 414, and two return springs 415. The base rod 410 provides a fixed mounting carrier for the third slide rail 411. The two stop plates 413 limit the movement of the two force-bearing blocks 412 while also ensuring that the return springs 415 do not bend when compressed. The base rod 410 is fixedly mounted horizontally at the bottom of the side plate 30. The third slide rail 411 is fixedly mounted on one side of the base rod 410. The two slide tables 414 are slidably mounted on the third slide rail 411. The two stop plates 413 are symmetrically and fixedly mounted on both sides of the base rod 410. The two force-bearing blocks 412 are symmetrically mounted on both sides of the base rod 410. The two force blocks 412 are placed at both ends of the third slide rail 411 and are limited to sliding within the two stop plates 413. Two return springs 415 are symmetrically welded between the corresponding force blocks 412 and the slide table 414. A middle partition block 4110 is fixedly provided in the middle of the third slide rail 411. The middle partition block 4110 is to prevent the two slide tables 414 from sticking together so that the two pressing rods 401 are vertically parallel. When the pressing rods 401 are in an outward V-shape displacement, the two pressing rods 401 respectively drive the two slide tables 414 to slide back and forth along the third slide rail 411. At this time, the two slide tables 414 compress the corresponding two return springs 415. After the two return springs 415 are deformed, they respectively drive the two force blocks 412 to slide within the two stop plates 413.
[0039] Reference Figure 7 and Figure 9Each drag-reducing assembly 50 shown includes a connecting plate 500, a limiting plate 501, a short rack 502, a first gear 503, a second gear 504, a connecting column 505, a fixing rod 506, and a guide plate 507. The connecting plate 500 provides a limiting rotation mounting carrier for the first gear 503 and the second gear 504. The fixing rod 506 and the connecting column 505 ensure that the guide plate 507 rotates with the second gear 504. The connecting plate 500 is horizontally fixed to the end of the corresponding drag-reducing plate 413. One end of the short rack 502 is fixed to one side of the corresponding force-bearing block 412. The first gear 503 is limited and rotated on the connecting plate 500, and the first gear 503 meshes with the short rack 502. The second gear 504 meshes with the side of the first gear 503. One end of the connecting column 505 is rotatably mounted on the connecting plate 500, and the connecting column 505 meshes with the second gear 504. 504 is fixedly connected, and the limiting plate 501 is fixedly set on one side of the connecting plate 500. The limiting plate 501 has a clearance opening 5010 on one side, which provides clearance space for the short rack 502. The fixing rod 506 is fixedly set on the other end of the connecting column 505. The air guide plate 507 is fixedly connected to one side of the fixing rod 506. When the two force blocks 412 slide in the two blocking plates 413, each force block 412 drives the short rack 502 to move. The short rack 502 drives the first gear 503 to rotate clockwise. The first gear 503 drives the second gear 504 to rotate counterclockwise. Thus, the second gear 504 drives the fixing rod 506 to rotate counterclockwise through the connecting column 505. Then, the fixing rod 506 drives the wind deflector 300 to rotate along one side. The two adjacent air guide plates 507 form a V-shape. When the airflow comes, it can be guided from both sides of the two air guide plates 507.
[0040] Working principle: When a section of the crossarm angle steel member of transmission tower 1 is corroded, causing structural strength failure and posing a safety hazard, the adjusting handle 228 is rotated. The adjusting handle 228 drives the corresponding screw 225 to rotate, which in turn drives the bevel gear 227 on it to rotate. The two bevel gears 227 are meshed, so the two screws 225 rotate synchronously. The two screws 225 respectively drive the two corresponding slide blocks 223 to slide on the two first slide rails 222, so that the two slide blocks 223 respectively drive the top ends of the two support rods 313 to move. In turn, the other ends of the two support rods 313 drive the two sliders 312 to move downward along the two second slide rails 310. At this time, the two sliders 312 drive the lower push rod 400 to move downward, and the lower push rod 400 drives the bottom... The two downward pressure rods 401 of the part are displaced in an outward V-shape. The two downward pressure rods 401 respectively drive the two slide tables 414 to slide in opposite directions along the third slide rail 411. At this time, the two slide tables 414 compress the corresponding two return springs 415. After the two return springs 415 are deformed, they respectively drive the two force blocks 412 to slide in the two stop plates 413. Each force block 412 drives the short rack 502 to move. The short rack 502 drives the first gear 503 to rotate clockwise. The first gear 503 drives the second gear 504 to rotate counterclockwise. Thus, the second gear 504 drives the fixed rod 506 to rotate counterclockwise through the connecting column 505. Then, the fixed rod 506 drives the wind deflector 300 to rotate along one side. At this time, one end of the short rack 502 is located in the clearance opening 5010.
