Description

Technical Field

[0001] This invention relates to the field of tower reinforcement technology, specifically to a support reinforcement device for angle steel towers. Background Technology

[0002] Currently, steel towers are commonly used basic relay facilities in power transmission and communication systems. The reinforcement device for the support column of angle steel tower can improve the stability and safety of the tower. Under normal circumstances, angle steel towers may be subjected to various external forces during long-term use, such as wind force, seismic force, conductor tension, etc., as well as possible corrosion, fatigue and other problems, which may lead to a decrease in the load-bearing capacity of the support column or deformation. The purpose of the reinforcement device is to remedy and strengthen these problems.

[0003] During the reinforcement process, there is a certain gap between the reinforcement device and the angle steel plate of the angle steel column. In windy weather, due to the existence of tiny gaps, the center position of the angle steel wrapped in the reinforcement will deform slightly outward due to the stress, resulting in an unsatisfactory reinforcement effect. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a support reinforcement device for an angle steel tower, comprising:

[0005] An external clamping assembly for securing the angle steel support column of the angle steel tower to the outside;

[0006] The inner clamping assembly is used to fix the inner side of the angle steel column of the angle steel tower, and works with the outer clamping assembly to reinforce the column of the angle steel tower.

[0007] Bolts are used to secure the outer clamping assembly and the inner clamping assembly;

[0008] An adjustment assembly for improving the tightness between the reinforcement device and the angle iron tower support, and the adjustment assembly is installed inside the outer clamping assembly;

[0009] The adjusting assembly includes an inner pad plate, both sides of which are fixedly connected to the inner wall of the outer clamping assembly. The inner pad plate is symmetrically installed along the center of the axis of the outer clamping assembly. An inner column block is fixedly installed at the center of the side of the inner pad plate away from the inner clamping assembly. A connecting plate is slidably installed on the outer side of the inner column block. A column groove is formed on the outer side of the connecting plate, and the connecting plate is slidably adapted to the inner column block through the column groove. Inner clamping plates are fixedly installed on the non-opposing sides of the connecting plate. The side of the inner clamping plate away from the inner clamping assembly is inclined. The inclined surface of the inner clamping plate is adapted to the adjusting groove of the outer clamping plate. When the worker rotates the threaded column, the inner clamping plate moves to both sides, and simultaneously moves inward a certain distance, so that the angle steel support... After the column is reinforced and wrapped on both the inner and outer sides, an inward clamping force is applied to both sides of the outer wrapping position to prevent the angle steel column from deforming slightly outward at the center of the reinforcement due to a certain gap. This improves the fit with the angle steel column while applying pressure to enhance the reinforcement effect. The outer side of the connecting plate away from the column groove is fixedly connected to a fixing plate, and the outer side of the fixing plate away from the connecting plate is fixedly connected to a threaded ring. The inner wall of the threaded ring is threaded, and the inner wall of the threaded ring is threaded with a threaded rod. The threaded rod is located on the outside of the outer clamping assembly, and a hexagonal block is fixedly installed at the end of the threaded rod that is close to each other.

[0010] Preferably, the outer clamping assembly includes an outer curved plate, which is a curved steel plate. The outer curved plate has symmetrically formed fixing grooves on its outer side. Bolts are installed through these fixing grooves to fix the outer curved plate to the inner clamping assembly. Inclined grooves are formed at the center of both the upper and lower ends of the outer curved plate, and external tilting plates are fixedly installed at each of these grooves. The tilting angle of the external tilting plates relative to the outer curved plate allows the reinforcement device to adjust the angle steel support column's position when reinforcing it. The angle of the angle steel connection provides bending space, allowing the reinforcement device to better fit the two angle steels of the angle steel column when reinforcing the connection position, providing highly effective support for the reinforcement of the connection position of the two angle steels. The end of the outer curved plate away from the outer clamping plate is inclined outward. The outer side of the outer clamping plate is symmetrically provided with adjustment grooves. The adjustment grooves are inclined grooves with both ends. The adjustment grooves of the outer clamping plate are slidably adapted to the inner clamping plate, and the adjustment grooves of the outer clamping plate are fixedly connected to both sides of the inner pad plate.

[0011] Preferably, the inner clamping assembly includes a sleeve column, with rotating buckles rotatably installed at both ends of the sleeve column. The sleeve column is rotatably connected to an inner rotating plate via the rotating buckles. The outer side of the inner rotating plate, away from the sleeve column, has symmetrically formed column grooves. The inner rotating plate is fixedly connected to the outer clamping curved plate via bolts using the column grooves. An inner top strip is fixedly installed at the center of the outer side of the sleeve column. The protrusion at the center of the inner top strip fits into the groove on the inner side of the angle steel plate of the angle steel column. After installation, the inner top strip presses against the angle steel groove at the reinforcement position, so that when the angle steel column is under force, the force limit of the steel column is improved due to the restriction and support of the inner top strip. A strip-shaped protrusion is provided at the center of the outer side of the inner top strip, and slots are formed on the outer side of the inner rotating plate. A slot frame is fixedly installed on the side of the inner rotating plate away from the outer clamping curved plate.

[0012] Preferably, the slot frame is symmetrically installed along the center of the inner rotating plate, and the slot frame is located in the empty slot of the inner rotating plate. An elastic pad is fixedly installed on the inner wall of the slot frame, and a limiting plate is fixedly installed on the outer side of the elastic pad. The outer side of the limiting plate is slidably adapted to the inner wall of the slot frame, and a friction plate is fixedly installed at the center of the outer side of the limiting plate. Through the elastic deformation of the elastic pad, after fixing, the friction plate, which is in contact with the inner wall of the angle steel plate, transmits the contact pressure to the elastic pad, causing it to deform. During the repeated stress on the angle steel column in different directions, the elastic pad, through the rebound force caused by the deformation, keeps the friction plate tightly pressed against the inner side of the angle steel plate, avoiding displacement of the reinforcement device itself and the reinforcement position under repeated stress in different directions, which would reduce the reinforcement effect. The two sides of the friction plate are slidably adapted to the empty slot of the inner rotating plate.

[0013] This invention provides a support reinforcement device for angle iron towers. It has the following beneficial effects:

[0014] 1. The support reinforcement device for this angle steel tower uses the inclined surface of the inner clamping plate and the adjustment groove of the outer clamping plate to match. When the worker rotates the threaded column, the inner clamping plate moves to both sides and simultaneously moves inward a certain distance. After the angle steel support is reinforced and wrapped by both the inner and outer sides, an inward clamping force is applied to both sides of the outer wrapping position. This prevents the angle steel support from deforming slightly outward at the center of the reinforcement due to a certain gap in the center of the reinforcement, which would otherwise occur in windy weather. This improves the fit with the angle steel support while applying pressure, thus enhancing the reinforcement effect.

[0015] Second, the support reinforcement device of the angle steel tower, through the tilting angle of the outer tilting plate and the outer clamping plate, allows the reinforcement device to provide bending space according to the angle steel connection angle of the angle steel support when reinforcing the connection position. This allows the reinforcement device to better fit the two angle steels of the angle steel support when reinforcing the connection position, providing effective support for the reinforcement of the connection position of the two angle steels.

[0016] Third, the support reinforcement device of the angle steel tower is designed so that the protrusion at the center of the inner top bar fits into the groove on the inner side of the angle steel plate of the angle steel support. After installation, the inner top bar is pressed against the groove of the angle steel at the reinforcement position, so that when the angle steel support is under stress, the stress limit of the steel is increased due to the restriction and support of the inner top bar.

[0017] IV. The support reinforcement device for the angle steel tower utilizes the elastic deformation of the elastic pad. After fixing, the friction plate, which is in contact with the inner wall of the angle steel plate, transmits the contact pressure to the elastic pad, causing it to deform. During the repeated stress on the angle steel support in different directions, the elastic pad, through the rebound force caused by the deformation, keeps the friction plate tightly pressed against the inner side of the angle steel plate. This prevents displacement of the reinforcement device itself and the reinforcement position under repeated stress in different directions, thus avoiding a reduction in the reinforcement effect.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] First embodiment, such as Figures 1 to 2 and Figures 5 to 6 As shown, the present invention provides a technical solution: a support reinforcement device for an angle iron tower, comprising:

[0030] External clamping assembly 1, which is used to fix the angle steel column of the angle steel tower to the outside;

[0031] The inner clamping component 4 is used to fix the inner side of the angle steel column of the angle steel tower and cooperates with the outer clamping component 1 to reinforce the column of the angle steel tower.

[0032] Bolt 3 is used to fix the outer clamping assembly 1 and the inner clamping assembly 4;

[0033] Adjustment component 2, which is used to improve the tightness between the reinforcement device and the angle iron tower support, and the adjustment component 2 is installed inside the outer clamping component 1;

[0034] The adjusting component 2 includes an inner pad 23, which is fixedly connected to the inner wall of the outer clamping component 1 on both sides. The inner pad 23 is symmetrically installed along the center of the axis of the outer clamping component 1. An inner column block 28 is fixedly installed at the center of the side of the inner pad 23 away from the inner clamping component 4. A connecting plate 21 is slidably installed on the outer side of the inner column block 28. A column groove is opened on the outer side of the connecting plate 21. The connecting plate 21 is slidably adapted to the inner column block 28 through the column groove. Inner clamping plates 22 are fixedly installed on the non-opposing sides of the connecting plate 21. The side of the inner clamping plate 22 away from the inner clamping component 4 is inclined. The worker uses a wrench to wrench the hexagonal block 24 on the outside and turns the hexagonal block 24. During the turning process, the hexagonal block 24 drives the threaded rod 26 to rotate, so that the threaded rod 26 changes the threaded connection position inside the threaded ring 27, increasing the distance between the threaded rings 27. The fixed plate 25 drives the connecting plate 21 to move, increasing the distance between the connecting plates 21. The inner column block 28 is fixed to the inner wall of the outer clamping plate 11 by the inner pad plate 23 through the sliding adaptation of the column groove of the connecting plate 21 and the inner column block 28, thus restricting the sliding direction of the connecting plate 21. The connecting plate 21 drives the inner clamping plate 22 to slide up and down along the adjustment groove 14 of the outer clamping plate 11. The outer side of the connecting plate 21 away from the column groove is fixedly connected to a fixing plate 25. The fixing plate 25 away from the connecting plate 21 is fixedly connected to a threaded ring 27. The inner wall of the threaded ring 27 is provided with threads, and the inner wall of the threaded ring 27 is threadedly connected to a threaded rod 26. The threaded rod 26 is located on the outer side of the outer clamping assembly 1. During the sliding process, according to the cooperation between the inclined surface of the adjustment groove 14 and the inclined surface of the inner clamping plate 22, the inner clamping plate 22 moves inward synchronously during the sliding process to both sides, applying pressure to the outer side of the angle steel column. The ends of the threaded rods 26 that are close to each other are fixedly installed with hexagonal blocks 24.

[0035] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 3 to 4As shown, the outer clamping assembly 1 includes an outer clamping curved plate 11, which is a curved steel plate. The outer clamping curved plate 11 has symmetrically arranged fixing grooves 12 on its outer side. Bolts 3 are installed on the outer clamping curved plate 11 through the fixing grooves 12 to fix it to the inner clamping assembly 4. The outer clamping curved plate 11 is attached to the outer side of the angle steel column. During attachment, the adjusting assembly 2 is attached to the outer side of the angle steel column, thus wrapping the angle steel column. Inclined grooves are provided at the center of both the upper and lower ends of the outer clamping curved plate 11, and outer lifting plates 13 are fixedly installed at the inclined grooves of the outer clamping curved plate 11. The outer curved plate 13 is inclined outward at the end away from the outer curved plate 11. The outer curved plate 11 is symmetrically provided with adjustment grooves 14. The adjustment grooves 14 are inclined grooves with both ends. The adjustment grooves 14 of the outer curved plate 11 are slidably adapted to the inner clamping plate 22. During the wrapping process, the outer curved plate 13 at the center of the upper and lower ends of the outer curved plate 11 provides a certain bending angle for the angle steel at the connection and reinforcement position. At the inclined connection position of the support angle steel, the outer curved plate 11 can be better reinforced at the bending point. The adjustment grooves 14 of the outer curved plate 11 are fixedly connected to both sides of the inner pad plate 23.

[0036] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 9 As shown, the inner clamping assembly 4 includes a sleeve post 41. Rotary buckles 45 are rotatably mounted at both the upper and lower ends of the sleeve post 41. An inner rotating plate 42 is rotatably connected to the sleeve post 41 via the rotating buckles 45. A column groove is symmetrically formed on the outer side of the inner rotating plate 42 away from the sleeve post 41. The inner rotating plate 42 is fixedly connected to the outer clamping curved plate 11 via bolts 3 using the column groove. An inner top strip 46 is fixedly installed at the center of the outer side of the sleeve post 41. A strip-shaped protrusion is provided at the center of the outer side of the inner top strip 46. Hollow grooves are formed on the outer sides of the inner rotating plate 42, which are then fixedly connected via bolts. 3. After the inner rotating plate 42 is fixedly connected to the outer curved plate 11, the inner top strip 46 at the center of the outer side of the sleeve column 41 is fitted and tightened with the groove at the center of the inner side of the angle steel. At the same time, the sleeve column 41 is rotatably connected to the inner rotating plate 42 through the rotating buckle 45, so that the inner rotating plate 42 can be adjusted according to the bending angle of the angle steel. The inner rotating plate 42 drives the limiting plate 44 through the groove frame 43, so that the friction plate 47 and the inner rotating plate 42 are pressed against the inner side of the angle steel column. The groove frame 43 is fixedly installed on the side of the inner rotating plate 42 away from the outer curved plate 11.

[0037] The slot frame 43 is symmetrically installed at the center of the axis of the inner rotating plate 42, and the slot frame 43 is located in the empty slot of the inner rotating plate 42. An elastic pad 48 is fixedly installed on the inner wall of the slot frame 43, and a limiting plate 44 is fixedly installed on the outer side of the elastic pad 48. The outer side of the limiting plate 44 slides and adapts to the inner wall of the slot frame 43, and a friction plate 47 is fixedly installed at the center of the outer side of the limiting plate 44. After the inner rotating plate 42 and the outer clamping plate 11 are tightened, the elastic pad 48 deforms under pressure and generates a rebound force, pressing the friction plate 47 tightly, so that the friction plate 47 fits against the inner side of the angle steel column, and the two sides of the friction plate 47 slide and adapt to the empty slot of the inner rotating plate 42.

[0038] During use, workers reinforce the load-bearing points of the angle steel support column according to the tower design. The outer clamping component 1 and the inner clamping component 4 are respectively attached to the inner and outer sides of the angle steel support column, and the inner clamping component 4 and the outer clamping component 1 are fixed together with bolts 3. Then, the workers use a wrench to turn the adjusting component 2 so that the adjusting component 2 is adjusted inside the outer clamping component 1, thereby improving the tightness of the fit between the reinforcement device and the angle steel support column.

[0039] When the worker attaches the outer clamping component 1 and the inner clamping component 4 to the inner and outer sides of the angle steel, the outer clamping curved plate 11 is attached to the outer side of the angle steel column during the attachment process. At the same time, the adjusting component 2 is attached to the outer side of the angle steel column, and the angle steel column is wrapped on the outside. During the wrapping process, the outer curved plate 13 at the center of the upper and lower ends of the outer clamping curved plate 11 provides a certain bending angle for the angle steel at the connection and reinforcement position. At the inclined connection position of the column angle steel, the outer clamping curved plate 11 can provide better reinforcement at the bending point.

[0040] After the inner clamping assembly 4 and the outer clamping assembly 1 are fixedly connected by bolts 3, the worker uses a wrench to tighten the hexagonal block 24 by clamping it on the outside. During the tightening process, the hexagonal block 24 drives the threaded rod 26 to rotate, causing the threaded rod 26 to change the threaded connection position inside the threaded ring 27, increasing the distance between the threaded rings 27. This, in turn, causes the connecting plate 21 to move through the fixing plate 25, further increasing the distance between the connecting plates 21. The connecting plate 21 then connects with the inner column block 28 through the groove of the column. The sliding adaptation fixes the inner column block 28 to the inner wall of the outer curved plate 11 by the inner pad 23, restricting the sliding direction of the connecting plate 21. The connecting plate 21 drives the inner clamping plate 22 to slide up and down along the adjustment groove 14 of the outer curved plate 11. During the sliding process, according to the cooperation between the inclined surface of the adjustment groove 14 and the inclined surface of the inner clamping plate 22, the inner clamping plate 22 moves inward synchronously during the sliding process to both sides, applying pressure to the outside of the angle steel column.

[0041] In the inner clamping assembly 4, after the inner rotating plate 42 is fixedly connected to the outer clamping curved plate 11 by bolts 3, the inner top strip 46 at the center position of the outer side of the sleeve column 41 fits and tightens with the groove at the center position of the inner side of the angle steel. At the same time, the sleeve column 41 is rotatably connected to the inner rotating plate 42 through the rotating buckle 45, so that the inner rotating plate 42 can be adjusted according to the bending angle of the angle steel. The inner rotating plate 42 drives the limiting plate 44 through the groove frame 43, so that the friction plate 47 and the inner rotating plate 42 fit tightly against the inner side of the angle steel column. After the inner rotating plate 42 and the outer clamping curved plate 11 are tightened, the elastic pad 48 deforms under pressure, generates a rebound force, and tightens the friction plate 47, so that the friction plate 47 fits against the inner side of the angle steel column.

[0042] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
