Description

Technical Field

[0001] This invention relates to the field of angle steel tower technology, specifically to an earthquake-resistant angle steel tower. Background Technology

[0002] Angle steel towers are a commonly used type of steel tower design. The tower body is composed of angle steel bars connected by bolts, forming a steel structure. Its main load-bearing components consist of four tower columns connected by angle steel bars, creating a truss-like, tall steel structure. This type of tower has high rigidity, minimal deformation, and uses angle steel for almost all connecting parts, simplifying the manufacturing process. Furthermore, the truss structure of angle steel towers, composed of angle steel bars, significantly improves transportation costs and ease of installation, resulting in a shorter construction period.

[0003] Angle steel towers are typically built on the ground or rooftops. Rooftop-mounted angle steel towers are often built to provide elevated space for communication equipment. Due to their high position above the ground, they are susceptible to strong winds and structural instability, causing vibrations to occur both the tower itself and the installed equipment. Existing earthquake-resistant methods mostly rely on adding reinforcing ribs and stiffeners to assist in earthquake resistance. However, this method is limited and only provides segmented, staged protection, resulting in poor effectiveness, especially during strong winds. Therefore, we propose an angle steel tower design that enhances earthquake resistance. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an earthquake-resistant angle steel tower with strong earthquake resistance, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a seismic-resistant angle steel tower, comprising a bottom side grounding plate, a seismic-resistant mechanism, a seismic-resistant stress relief mechanism, a wind-driven mechanism, and a wire stabilization mechanism;

[0006] Vertical rods are fixedly connected to the four corners of the upper surface of the bottom side of the floor;

[0007] The seismic-resistant mechanism includes circular connecting blocks and rectangular stabilizers. The circular connecting blocks are fixedly connected to the outer arc surfaces of the four vertical bars respectively. Every four circular connecting blocks located on the same plane are fixedly connected to the outer end of a rectangular stabilizer. An installation plate is fixedly connected inside the upper rectangular stabilizer.

[0008] The seismic stress relief mechanism is located between the bottom side floor plate and the mounting plate;

[0009] The wind-driven mechanism is located on the upper surface of the mounting plate, and the lower end of the wind-driven mechanism is fixedly connected to the upper end of the anti-vibration and stress-relieving mechanism.

[0010] The cable stabilization mechanism is located on the outer side of the mounting plate, which can mitigate the vibration caused by strong winds from multiple directions when facing strong winds.

[0011] Furthermore, the seismic-resistant mechanism includes anti-seismic beams, which are fixedly connected to the interior of three rectangular stabilizers to achieve the function of stable seismic resistance.

[0012] Furthermore, the seismic damping mechanism includes a rotating column, external threads, limiting blocks, cross sliders, cross grooves, connecting rods, dampers, and fixed seats. The rotating column is rotatably connected to the middle of the bottom ground plate and the mounting plate. The outer arc surface of the rotating column is provided with uniformly distributed limiting blocks, and the outer arc surface of the rotating column is provided with uniformly distributed external threads. The external threads are located between every two adjacent limiting blocks. The external thread surface of each section of the external thread is threadedly connected to a cross slider. The cross ends of the three cross sliders are all provided with cross grooves. The interior of each of the twelve cross grooves is rotatably connected to a connecting rod through a rotating shaft. The upper end of each of the twelve connecting rods is fixedly connected to a damper. The side of each of the twelve anti-seismic beams facing the center of the bottom ground plate is fixedly connected to a fixed seat. The interior of each of the twelve fixed seats is rotatably connected to the upper side of the telescopic end of the damper corresponding to the position, thus counteracting the vibration force generated by the vertical rod.

[0013] Furthermore, the seismic stress relief mechanism also includes a reset assembly, which comprises a bottom circular sealing box, a lower spiral spring, an upper circular sealing box, and an upper spiral spring. The bottom circular sealing box is fixedly connected to the upper surface of the bottom contact plate, and the upper circular sealing box is fixedly connected to the lower surface of the mounting plate. The upper spiral spring is fixedly connected to the upper end of the outer arc surface of the rotating column, and the upper spiral spring is located inside the upper circular sealing box. The outer end of the upper circular sealing box is fixedly connected to the inner wall of the upper circular sealing box. The lower spiral spring is fixedly connected to the lower end of the outer arc surface of the rotating column, and the lower spiral spring is located inside the bottom circular sealing box. The outer end of the lower spiral spring is fixedly connected to the inner wall of the bottom circular sealing box. Both the upper and bottom circular sealing boxes are rotatably connected to the rotating column for reversing the rotation of the column to reset it.

[0014] Furthermore, the wind-driven mechanism includes a drive plate, a wind-driven rotating rod, fan blades, an upper limiting cap, and air guides. The drive plate is fixedly connected to the upper surface of the mounting plate. The wind-driven rotating rod is rotatably connected to the middle of the drive plate. The lower end of the wind-driven rotating rod is fixedly connected to the upper end of the rotating column. The outer arc surface of the wind-driven rotating rod is fixedly connected to evenly distributed fan blades. The upper end of the wind-driven rotating rod is fixedly connected to an upper limiting cap. The outer arc surface of the upper limiting cap has evenly distributed air guides, providing driving force for the rotating rod.

[0015] Furthermore, it also includes a top mounting bracket, which is fixedly connected to the upper surface of the mounting plate to achieve the installation function.

[0016] Furthermore, the wire stabilization mechanism includes a horizontal trapezoidal frame, binding shafts, binding steel ropes, and mounting rods. The horizontal trapezoidal frames are respectively fixedly connected to the lower left and lower right sides of the top mounting frame. Binding shafts are symmetrically fixedly connected to the upper surfaces of the two horizontal trapezoidal frames at the ends away from the center of the top mounting frame. All four binding shafts are fixedly connected to the upper end of the top mounting frame through binding steel ropes. Mounting rods are fixedly connected between the left and right inner walls of the two horizontal trapezoidal frames. The lower surfaces of the two mounting rods are provided with evenly distributed wire connection ports to realize the function of connecting external equipment.

[0017] Furthermore, it also includes bottom gripping plates, which are fixedly connected to the four outer sides of the bottom grounding plate, and the four bottom gripping plates are fixedly connected to evenly distributed grounding stakes inside, so as to realize the function of large-area grounding.

[0018] Furthermore, it also includes steel cables, which are fixedly connected to the front and rear sides of the mounting plate respectively. The lower ends of the two steel cables are fixedly connected to the upper surface of the bottom gripping floor, which enables the mounting plate and the gripping floor to present a triangular stability function.

[0019] Furthermore, it also includes a cross-shaped fixing bracket, which is evenly distributed between the four vertical bars to enhance the stability between the vertical bars.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. When the drive is completed by wind power, the rotating column will stop rotating when the upper surface of the limit block is locked against the cross slider. At this time, the wind passing through the surface of the fan blade will be discharged through the air guide on the upper limit cap to ensure that the fan blade does not break. After the wind power disappears, the upper and lower vortex springs will drive the rotating column to rotate in the opposite direction to reset the rotating column and prevent the fan blade from breaking due to strong wind.

[0022] 2. When the angle steel frame is in operation and seismic work is required, the vertical poles will tilt. At this time, it is affected by the anti-seismic beams. The anti-seismic beams form triangular structures with the four corners of the three rectangular stabilizers, which improves the internal stability of the rectangular stabilizers, ensures the stability of the rectangular stabilizers, and ensures that the vertical poles will not tilt, thereby improving the stability of the entire angle steel frame.

[0023] 3. When the wind is strong, the wind will blow the fan blades, which will then drive the wind-driving rod to rotate, which in turn drives the rotating column to rotate, and then drives the external thread on the rotating column to rotate. At this time, the three cross sliders will adjust their positions downwards simultaneously. At this time, the twelve connecting rods will move downwards, which will drive the dampers to move downwards. The twelve dampers will pull the anti-vibration beam through the fixed seat, and then hold the four vertical rods tightly through the three rectangular stabilizers to ensure their stability. When the dampers move downwards, the cross groove and the fixed seat will provide angle adaptation for the dampers. When the three cross sliders are restricted in position by the limit block, they will reset, which will drive each damper to reset. When facing strong winds, it can mitigate the vibration effect of strong winds from multiple directions. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-7 This embodiment provides an earthquake-resistant angle steel tower, including a bottom side grounding plate 1, an earthquake-resistant mechanism 3, an earthquake-resistant stress relief mechanism 4, a wind-driven mechanism 6, and a wire stabilization mechanism 8.

[0034] Vertical rods 2 are fixedly connected to the four corners of the upper surface of the bottom side base plate 1, and a cross fixing bracket 12 is also included. The cross fixing bracket 12 is evenly arranged between the four vertical rods 2.

[0035] The seismic-resistant mechanism 3 includes circular connecting blocks 31 and rectangular stabilizers 32. The circular connecting blocks 31 are fixedly connected to the outer arc surfaces of the four vertical rods 2. Each set of four circular connecting blocks 31 located on the same plane is fixedly connected to the outer end of a rectangular stabilizer 32. An installation plate 5 is fixedly connected inside the upper rectangular stabilizer 32. The seismic-resistant mechanism 3 includes anti-vibration beams 33, which are fixedly connected to the interiors of the three rectangular stabilizers 32. It also includes a top mounting bracket 7, which is fixedly connected to the upper surface of the mounting plate 5. The bottom gripping plates 9 are fixedly connected to the four outer sides of the bottom contact plate 1. The interiors of the four bottom gripping plates 9 are fixedly connected to the four outer sides of the bottom contact plate 1. The fixed connection includes evenly distributed grounding stakes 10 and steel cables 11. The steel cables 11 are fixedly connected to the front and rear sides of the mounting plate 5, respectively. The lower ends of the two steel cables 11 are fixedly connected to the upper surface of the bottom gripping plate 9. The angle steel tower is installed to the designated work position through the grounding stakes 10 on the bottom gripping plate 9. When the angle steel tower is blown by the wind, the vertical pole 2 will tilt due to the ductility of the steel itself. At this time, it is affected by the structure of the anti-vibration beam 33. The anti-vibration beam 33 is distributed at the four corners of the rectangular stabilizer 32, forming a triangular stable structure, which ensures the stability of the rectangular stabilizer 32, and thus ensures that the vertical poles 2 will not vibrate or tilt.

[0036] The seismic relief mechanism 4 is located between the bottom ground plate 1 and the mounting plate 5. The seismic relief mechanism 4 includes a rotating column 41, external threads 42, limiting blocks 43, cross sliders 44, cross grooves 45, connecting rods 46, dampers 47, and a fixed base 48. The rotating column 41 is rotatably connected to the middle of the space between the bottom ground plate 1 and the mounting plate 5. The outer arc surface of the rotating column 41 is provided with evenly distributed limiting blocks 43, and the outer arc surface of the rotating column 41 is provided with evenly distributed external threads 42. The external threads 42 are located between every two adjacent limiting blocks 43. Each section of the external thread 42 is threadedly connected to a cross slider 44. The cross ends of the three cross sliders 44 are each provided with cross grooves 45. The interiors of the twelve cross grooves 45 are rotatably connected to connecting rods via rotating shafts. The upper ends of the twelve connecting rods 46 are all fixedly connected to dampers 47. In this embodiment, the dampers 47 are VFD-1500 viscous fluid dampers. The sides of the twelve anti-vibration beams 33 facing the center of the bottom ground plane 1 are all fixedly connected to fixed seats 48. The interiors of the twelve fixed seats 48 are rotatably connected to the upper side of the telescopic end of the corresponding damper 47. The anti-vibration force relief mechanism 4 also includes a reset assembly. The reset assembly includes a bottom circular sealing box 491, a lower spiral spring 492, an upper circular sealing box 493, and an upper spiral spring 494. The bottom circular sealing box 491 is fixedly connected to the upper surface of the bottom ground plane 1. The lower surface of the mounting plate 5 is fixedly connected to the upper circular sealing box 493. The upper end of the outer arc surface of the rotating column 41 is fixedly connected to the upper surface of the bottom ground plane 1. An upper spiral spring 494 is fixedly connected to the upper circular sealing box 493. The upper spiral spring 494 is located inside the upper circular sealing box 493, and the outer end of the upper circular sealing box 493 is fixedly connected to the inner wall of the upper circular sealing box 493. A lower spiral spring 492 is fixedly connected to the lower end of the outer arc surface of the rotating column 41. The lower spiral spring 492 is located inside the bottom circular sealing box 491, and the outer end of the lower spiral spring 492 is fixedly connected to the inner wall of the bottom circular sealing box 491. Both the upper circular sealing box 493 and the bottom circular sealing box 491 are rotatably connected to the rotating column 41. If the wind force is strong, the wind will blow the fan blade 63, which will drive the wind-driving rotating rod 62 to rotate, which will drive the rotating column 41 to rotate, which will drive the external thread 42 on the rotating column 41 to rotate. At this moment, the three cross sliders 44 simultaneously adjust their positions downwards. At this time, the twelve connecting rods 46 move downwards, which in turn drives the dampers 47 to move downwards. The twelve dampers pull the anti-vibration beam 33 through the fixed seat 48, and then the three rectangular stabilizers 32 tightly hold the four vertical rods 2, ensuring their stability. When the dampers 47 move downwards, the cross rotating groove 45 and the fixed seat 48 provide angle adaptation for the dampers 47. When the three cross sliders 44 are restricted in position by the limit block 43, when the upper surface of the limit block 43 presses against the cross sliders 44, the rotating column 41 stops rotating. The upper vortex spring 494 and the lower vortex spring 492 drive the rotating column 41 to rotate in the opposite direction, which in turn drives the three cross sliders 44 to reset and drive each damper 47 to reset.

[0037] Wind-driven mechanism 6: It is set on the upper surface of the mounting plate 5. The lower end of the wind-driven mechanism 6 is fixedly connected to the upper end of the anti-vibration and force-relieving mechanism 4. The wind-driven mechanism 6 includes a drive plate 61, a wind-driven rotating rod 62, a fan blade 63, an upper limit cap 64, and an air guide 65. The drive plate 61 is fixedly connected to the upper surface of the mounting plate 5. The wind-driven rotating rod 62 is rotatably connected to the middle of the drive plate 61. The lower end of the wind-driven rotating rod 62 is fixedly connected to the upper end of the rotating column 41. The outer arc surface of the wind-driven rotating rod 62 is fixedly connected to the evenly distributed fan blades 63. The upper end of the wind-driven rotating rod 62 is fixedly connected to the upper limit cap 64. The outer arc surface of the upper limit cap 64 is provided with evenly distributed air guides 65. At this time, the wind passing through the surface of the fan blades 63 is discharged from the air guides 65 on the upper limit cap 64 to ensure that the fan blades 63 do not break.

[0038] The wire stabilization mechanism 8 is located on the outer side of the mounting plate 5. The wire stabilization mechanism 8 includes a horizontal trapezoidal frame 81, a binding shaft 82, a binding steel rope 83, and a mounting rod 84. The horizontal trapezoidal frame 81 is fixedly connected to the lower left side and the lower right side of the top mounting frame 7, respectively. The upper surface of the two horizontal trapezoidal frames 81 is symmetrically fixedly connected to the end away from the center of the top mounting frame 7. The four binding shafts 82 are fixedly connected to the upper end of the top mounting frame 7 through the binding steel rope 83. The mounting rod 84 is fixedly connected between the left and right inner walls of the two horizontal trapezoidal frames 81. The lower surface of the two mounting rods 84 is provided with evenly distributed wire connection ports. At this time, the relevant equipment is connected to the external equipment through the wire connection ports on the top mounting frame 7 and the mounting rod 84.

[0039] The working principle of the earthquake-resistant angle steel tower provided by this invention is as follows:

[0040] The angle steel tower is installed on the designated location on the roof via the grounding stake 10 on the bottom gripping plate 9. At this point, the relevant equipment is connected to external devices through the wire connection ports on the top mounting frame 7 and the mounting rod 84. The angle steel tower is then ready for use. When exposed to wind, the vertical rod 2 may tilt due to the inherent ductility of steel. This is mitigated by the structure of the anti-vibration beam 33, which is distributed at the four corners of the rectangular stabilizer 32, forming a triangular stabilizing structure that ensures the stability of the rectangular stabilizer 32 and prevents vibration and tilting between the vertical rods 2. In strong winds, the wind will drive the fan blade 63, which in turn rotates the wind-driving rotating rod 62, which in turn rotates the rotating column 41, causing the external thread 42 on the rotating column 41 to rotate. Simultaneously, the three cross sliders 44 move downwards. During adjustment, the twelve connecting rods 46 move downwards, which in turn drives the dampers 47 to move downwards. The twelve dampers pull the anti-vibration beam 33 through the fixed seat 48, and then the three rectangular stabilizers 32 hold the four vertical rods 2 tightly, ensuring their stability. When the dampers 47 move downwards, the cross-shaped rotating groove 45 and the fixed seat 48 provide angle adaptation for the dampers 47. When the three cross-shaped sliders 44 are restricted in position by the limit block 43, and when the upper surface of the limit block 43 presses against the cross-shaped sliders 44, the rotating column 41 no longer rotates. At this time, the wind passing through the surface of the fan blade 63 is discharged through the air guide 65 on the upper limit cap 64, ensuring that the fan blade 63 does not break. After the wind disappears, the upper vortex spring 494 and the lower vortex spring 492 drive the rotating column 41 to rotate in the opposite direction, which in turn drives the three cross-shaped sliders 44 to reset and drive each damper 47 to reset.

[0041] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
