Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a reinforcement and vibration reduction device and its working method for the main material of steel pipe towers. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] With the advent of the information society, communication technology is impacting all aspects of our lives, and steel pipe towers play a vital role in the construction of power transmission lines. A steel pipe tower is a lattice-type tower structure composed primarily of steel pipes, with other components made of steel pipes or structural steel. It serves as the support structure for overhead power transmission lines, ensuring that the conductors meet distance requirements from the ground and other objects, and can withstand the loads of the conductors, lightning protection wires, and the tower itself, as well as external loads.

[0004] Currently, with the development of communication technology and the need for expansion and sharing of operator network systems, there is an increasing demand for adding rooftop systems to steel pipe towers beyond their original design load-bearing capacity. However, existing steel pipe towers have limited load-bearing capacity and cannot withstand high loads. Therefore, it is necessary to reinforce the steel pipe towers to ensure greater stability and extend their service life. Existing technologies for reinforcing the main materials to address insufficient load-bearing capacity have the following problems:

[0005] Reinforcement methods such as drilling holes and welding in the original tower body are not only limited by the difficulty of high-altitude operations, but may also weaken the cross-section of the original main material, thereby affecting the structural strength of the main material.

[0006] Welding adds internal stress, but this method is complex and cannot provide vibration reduction for the structure.

[0007] In addition, the reinforcement location is relatively fixed, and the device cannot be disassembled and reinstalled, making its applicability less than ideal. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the purpose of this invention is to provide a reinforcement and vibration reduction device for the main material of steel pipe towers, which can be adjusted according to the actual tower size and requirements, and will not lead to abandonment due to changes in reinforcement requirements or damage to the original structure due to re-reinforcement.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0010] A reinforcement and vibration reduction device for the main material of a steel pipe tower includes at least one side of a set section of the steel pipe tower. The reinforcement and vibration reduction device includes at least two sets of axial reinforcement components. Each axial reinforcement component is installed circumferentially in the steel pipe of the set section of the steel pipe tower. The axial reinforcement component includes a first reinforcement clamp and a second reinforcement clamp arranged vertically. At least one connecting rod is connected between the first reinforcement clamp and the second reinforcement clamp. The length of the connecting rod is adjustable. Both the first reinforcement clamp and the second reinforcement clamp are connected to a support member to play a reinforcement role. The support member is located on one side of the steel pipe.

[0011] A transverse vibration damping component is provided between the two first reinforcement clamps of two adjacent axial reinforcement components. The support is movably connected to the transverse vibration damping component at the first reinforcement clamp. The support is movably connected to one end of the oblique vibration damping component at the second reinforcement clamp. The other end of the oblique vibration damping component is connected to the transverse vibration damping component.

[0012] As described above, a reinforcement and vibration reduction device for the main material of a steel pipe tower is provided with the axial reinforcement component at all steel pipes at the set section of the steel pipe tower, and with the lateral vibration reduction component and the oblique vibration reduction component on each side of the steel pipe tower.

[0013] As described above, in a reinforcement and vibration reduction device for the main material of a steel pipe tower, the first reinforcement clamps of all the axial reinforcement components are set at the same height to ensure the balance of the force on the steel pipe tower.

[0014] The second reinforcing clamps of all the axially reinforced components are positioned at the same height.

[0015] As described above, a reinforcement and vibration reduction device for the main material of a steel pipe tower includes two inclined vibration reduction components, the top ends of which are connected to the middle of the transverse vibration reduction component.

[0016] The support member is a reinforcing angle steel with an L-shaped cross section. The reinforcing angle steel facilitates the connection with the fixing plates of the segmented parts on both sides, and also helps to increase the stress area of ​​the steel pipe by cooperating with the first reinforcing clamp and the second reinforcing clamp.

[0017] As described above, a reinforcement and vibration reduction device for the main material of a steel pipe tower has the same structure for the first reinforcement clamp and the second reinforcement clamp.

[0018] The first reinforcing clamp includes two segmented components that can be assembled into a cylinder surrounding the steel pipe. A fixing plate is provided on the end side of one of the segmented components at one of the assembly points. The fixing plate can be located on the outside of the support member so that the first reinforcing clamp fits into the support member. The fixing plate is fixedly connected to the side of the support member. The two segmented components are fixedly connected at the other assembly point.

[0019] As described above, a reinforcement and vibration reduction device for the main material of a steel pipe tower is provided at both ends of the segmented component, and multiple axial dampers are provided between the two axial end plates. The axial dampers are circumferentially fitted with axial springs, and the axial dampers are arranged parallel to the central axis of the cylinder formed by the segmented components.

[0020] The cylinder of the axial damper is fixed between two conformal end plates, and the piston rod of the axial damper is part of the connecting rod.

[0021] As described above, in a reinforcement and vibration reduction device for the main material of a steel pipe tower, the piston rod of the axial damper installed at the first reinforcement clamp is a first piston rod, and the piston rod of the axial damper installed at the second reinforcement clamp is a second piston rod.

[0022] The connecting rod includes a threaded sleeve, a first piston rod, and a second piston rod. The two ends of the threaded sleeve are connected to the connecting rods of the first and second piston rods respectively through a threaded structure, which can realize the adjustment of the length of the connecting rod and adjust the length of the control section according to the vibration reduction requirements.

[0023] As described above, a reinforcement and vibration reduction device for the main material of a steel pipe tower includes a lateral vibration reduction component comprising a central connector, lateral dampers on both sides of the central connector, a lateral spring circumferentially arranged on the cylinder of the lateral damper, and one end of the lateral damper connected to the support member via a first universal joint.

[0024] As described above, a reinforcement and vibration reduction device for the main material of a steel pipe tower includes an oblique vibration reduction component comprising an oblique damper, a second universal joint being provided at one end of the oblique damper, an oblique spring being provided between the cylinder of the oblique damper and the second universal joint, and the other end of the oblique damper being connected to the central connecting member.

[0025] Secondly, the present invention also provides a method for operating a reinforcement and vibration reduction device for the main material of a steel pipe tower, comprising the following:

[0026] Axial reinforcement components are installed circumferentially on both sides of the steel pipes on at least one side of the set section of the steel pipe tower. Supports are set on one side of the steel pipes, and the supports are connected to the first reinforcement clamp and the second reinforcement clamp respectively.

[0027] The two first reinforcing clamps of the two axial reinforcing components are connected by the transverse vibration damping component;

[0028] The oblique vibration damping component connects the transverse vibration damping component to the second reinforcing clamp;

[0029] The axial reinforcement component is located circumferentially in the steel pipe and connected to the support, increasing the load-bearing area of ​​the steel pipe and improving the structural strength of the steel pipe tower. Under load, the steel pipe tower effectively reduces its own vibration through the axial damping component, the lateral damping component and the oblique damping component.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1) In this invention, the reinforcement and vibration reduction device is set up such that the axial reinforcement component is located in the circumferential direction of the steel pipe and connected to the support component, which cooperates with the original structure to increase the stress area of ​​the steel pipe and improve the structural strength of the steel pipe tower without affecting the structural strength of the original main material; the axial vibration reduction component provides axial damping to the steel pipe, and the transverse vibration reduction component connects the axial vibration reduction components on both sides to effectively improve the structural stiffness of the steel pipe tower and reduce its own deformation. The transverse vibration reduction component provides lateral damping, and the oblique vibration reduction component provides oblique damping. Under the action of load, the vibration of the tower is effectively reduced by the axial vibration reduction component, the transverse vibration reduction component and the oblique vibration reduction component, thus avoiding its own deformation and changes in relative position.

[0032] 2) In this invention, the support is located on one side of the steel pipe. The support and the axial vibration damping component work together to bear the force. There is no need to drill holes and weld on the original structural steel pipe. This can avoid the redistribution of stress in the original structural steel pipe due to the installation of the reinforcement and vibration damping device, and will not affect the safety performance of the original structural steel pipe.

[0033] 3) The first and second reinforcing clamps in this invention have reasonable structural settings. They are assembled into a cylindrical structure by two segmented parts, which facilitates installation around the steel pipe. The end of each segmented part is provided with a fixing plate, which can be connected to the support to ensure a reliable connection between the first and second reinforcing clamps and the support.

[0034] 4) The first and second reinforcing clamps in this invention can be disassembled and reused, and the installation position is highly flexible. They can be used at different main material positions of the steel tower, and the angle and position can be adjusted according to the tower section size. The first and second reinforcing clamps are connected by an adjustable connecting rod, and the length of the connecting rod can be adjusted according to the position of the first and second reinforcing clamps to meet different vibration reduction requirements.

[0035] 5) In this invention, the axial damping component is equipped with an axial damper and an axial spring, the transverse damping component is equipped with a transverse damper and a transverse spring, and the oblique damping component is equipped with an oblique damper and an oblique spring. Each damper provides a reaction force when the structure vibrates and deforms. Each damper and the corresponding spring work together to achieve vibration reduction in each direction. They are linked with the corresponding spring to reduce the impact and damage of accidental loads on the structure. Attached Figure Description

Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0050] As described in the background section, there are problems in the prior art. In order to solve the above-mentioned technical problems, the present invention proposes a reinforcement and vibration reduction device for the main material of steel pipe towers.

[0051] Example 1

[0052] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a reinforcement and vibration reduction device for the main material of a steel pipe tower includes at least one side of a set section of the steel pipe tower. The reinforcement and vibration reduction device includes at least two sets of axial reinforcement components 1. Each axial reinforcement component 1 is installed circumferentially on the steel pipe 1-1 in the set section of the steel pipe tower. The axial reinforcement component 1 includes a first reinforcement clamp 1-2 and a second reinforcement clamp 1-7 arranged vertically. At least one connecting rod is connected between the first reinforcement clamp and the second reinforcement clamp. The length of the connecting rod is adjustable. Both the first reinforcement clamp and the second reinforcement clamp are connected to a support member to play a reinforcement role. The support member is located on one side of the steel pipe.

[0053] A transverse vibration damping component 2 is provided between the two first reinforcement clamps of two adjacent axial reinforcement components. The support is movably connected to the transverse vibration damping component at the first reinforcement clamp, and the support is movably connected to one end of the oblique vibration damping component at the second reinforcement clamp. The other end of the oblique vibration damping component is connected to the transverse vibration damping component.

[0054] In this embodiment, a reinforcement and vibration reduction device is installed on one side (the main pressure-bearing surface) of the steel pipe tower; the first reinforcement clamps of all axial reinforcement components are set at the same height to ensure the balance of the force on the steel pipe tower; the second reinforcement clamps of all axial reinforcement components are set at the same height.

[0055] The reinforcement and vibration damping device includes two inclined vibration damping components 3, the tops of which are connected to the middle of the transverse vibration damping component 2.

[0056] Support member 1-4 is an L-shaped reinforcing angle steel with the same width on both sides. This design facilitates connection to the fixing plates of the segmented components on both sides. The equilateral reinforcing angle steel is connected and secured to steel pipe 1-1 via a first or second reinforcing clamp, forming a... Figure 4 The cross section shown increases the stress-bearing area compared to steel pipe 1-1, thereby improving the overall structural strength. At the same time, due to the support of support member 1-4, the structural stiffness of the original steel pipe 1-1 is improved, avoiding its own deformation and changes in relative position.

[0057] In this embodiment, the first reinforcing clamp and the second reinforcing clamp have the same structure, and the first reinforcing clamp and the second reinforcing clamp can be disassembled and reused; see reference. Figure 3 As shown, the first reinforcing clamp includes two segmented parts, which can be assembled into a cylinder that surrounds the steel pipe. Fixing plates 1-2-7 are respectively provided on the end side of one of the segmented parts at one of the assembly points. The fixing plates can be located on the outside of the support member so that the first reinforcing clamp fits into the support member. The fixing plates are fixed to the side of the support member. The two segmented parts are fixed to the other assembly point.

[0058] Specifically, the segmented components are semi-circular. After the segmented components are assembled into a cylinder, the inner diameter is greater than or equal to the outer diameter of the steel pipe. The segmented components have a set length, and the free end of the segmented components is provided with lugs 1-2-4. The lugs have a set width, and the length of the lugs is the same as the length of the segmented components. When the two segmented components are assembled, the lugs fit together and are fastened by bolts on the lugs. The other end of the two segmented components is provided with fixing plates 1-2-7. After the two segmented components are assembled, the fixing plates on both sides are set at 90°. The side of the support component is fastened to the fixing plate by bolts, so that the support component is fastened to the steel pipe 1-1 and shares the force. There is no need to drill holes and weld on the steel pipe 1-1, which can avoid the redistribution of stress in the steel pipe due to the installation of the reinforcement and vibration damping device, and will not affect the safety performance of the original structural steel pipe.

[0059] Among them, stiffening ribs 1-2-3 are provided between the lugs 1-2-4 and the fixing plate 1-2-7 of the clamp and the semi-circular segment to reduce the deformation of the structure, improve the coordination between the support 1-4 and the original round steel 1-1, and improve the stability of the overall structure.

[0060] In this embodiment, conformal end plates 1-2-1 are respectively provided at both ends of the segmented component. The conformal end plates have a set width. One side of the conformal end plates is connected to the fixed plate. Multiple axial dampers 1-2-5 are provided between the two conformal end plates, specifically up to 8. An axial spring is circumferentially sleeved on the axial damper. The axial damper is parallel to the central axis of the cylinder assembled from the segmented components.

[0061] The cylinder of the axial damper is fixed between two conformal end plates. The piston rod of the axial damper is part of the connecting rod. The piston rod of the axial damper installed at the first reinforcing fixture is the first piston rod, and the piston rod of the axial damper installed at the second reinforcing fixture is the second piston rod.

[0062] In this embodiment, reference Figure 2 As shown, the connecting rod includes a threaded sleeve 1-5, a first piston rod, and a second piston rod. The two ends of the threaded sleeve are connected to the connecting rods of the first and second piston rods respectively through a threaded structure, which can realize the adjustment of the length of the connecting rod. The length of the control section can be adjusted according to the vibration reduction requirements. By setting the connecting rod, the vibration of the original structural steel pipe under wind load or other forms of load can be reduced.

[0063] One end of the axial damper is fixed to the conformal end plate 1-2-1 on one side, and the other end passes through the conformal end plate on the other side and is connected to the connecting rod. The axial damper is specifically an axial hydraulic rod. The one that passes through the conformal end plate on one side of the first reinforcing fixture is the first axial hydraulic cylinder, and the one that passes through the conformal end plate on one side of the second reinforcing fixture is the second axial hydraulic cylinder.

[0064] Specifically, the end of the second piston rod 1-6 away from the cylinder body of the second axial hydraulic cylinder is connected to the threaded connecting sleeve 1-5. The first piston rod 1-3 and the second piston rod 1-6 move along the length direction of the first axial hydraulic cylinder and the second axial hydraulic cylinder (that is, the length direction of the steel pipe) to adjust the internal oil pressure of the first axial hydraulic cylinder and the second axial hydraulic cylinder.

[0065] Axial springs 1-2-6 of equal height are arranged circumferentially around the cylinder bodies of the first and second axial hydraulic cylinders, spirally arranged around the outer sides of the cylinder bodies of the first and second axial hydraulic cylinders. One end of the axial spring is connected to the outer ring of the corresponding hydraulic cylinder body, forming a vibration damping device in the axial direction of the steel pipe through the combined action of hydraulic pressure and springs. The two axial hydraulic cylinders are fixed to the first and second reinforcing clamps. The base is equipped with a sealing gasket 1-2-2 to ensure airtightness. The connecting rod also serves as the piston rod of the axial hydraulic cylinder, providing a reaction force during structural vibration and deformation, and working in conjunction with the springs to mitigate the impact and damage of accidental loads on the structure.

[0066] It should be noted that, in order to connect the transverse vibration damping component 2 with the support, the support is provided with a fixed seat at the first reinforcing clamp, and the fixed seat is connected to the end of the transverse vibration damping component 2 through the first universal joint; the support is also provided with a chassis at the second reinforcing clamp, and a fixed seat is connected between the two sides of the support, and the fixed seat is connected to the end of the oblique vibration damping component through the second universal joint.

[0067] refer to Figure 5As shown, the transverse damping component 2 includes a central connector, which is cylindrical. Transverse dampers are respectively installed on both sides of the central connector. A transverse spring 2-2 is circumferentially installed on the cylinder of the transverse damper. End plates with increased diameters are installed on both sides of the central connector to limit the transverse springs. An end plate is also installed at the other end of the cylinder of the transverse damper to limit the other end of the transverse spring. One end of the transverse damper is connected to the support component through a first universal joint. A ball cage universal joint 2-3 is installed on one side of the central connector to achieve connection with the oblique damping component.

[0068] Specifically, the lateral damper includes a lateral hydraulic cylinder 2-1, a lateral piston rod 2-4, a universal joint fork 2-5 at the end of the lateral piston rod 2-4 away from the cylinder body, a fixed seat between the two sides of the support member, a rotating shaft base 4-4 supported at the fixed seat, another universal joint fork supported by the rotating shaft base 4-4, and a pin connecting the two universal joint forks to form the first universal joint.

[0069] The oblique damping assembly 3 includes an oblique damper. A second universal joint is provided at one end of the oblique damper. An oblique spring 3-4 is provided between the cylinder body of the oblique damper and the second universal joint. The other end of the oblique damper is connected to the middle connecting piece. Specifically, the oblique damper is an oblique hydraulic cylinder 3-3. A support rod is provided on one side of the oblique hydraulic cylinder. The oblique spring is sleeved on the support rod and located between the cylinder body of the oblique hydraulic cylinder and the first universal joint fork 4-1. A ball cage universal joint chassis 3-1 is provided at the end of the oblique piston connecting rod 3-2 of the oblique hydraulic cylinder away from its cylinder body for connection with the ball cage universal joint.

[0070] refer to Figure 6 As shown, the support member is equipped with a fixed seat, and a rotating shaft base 4-4 is set at the fixed seat. The rotating shaft base supports the second universal joint fork 4-3. The first universal joint fork and the second universal joint fork set at the end of the support rod in the inclined vibration damping assembly form a cross-shaped universal joint. A cross bearing 4-2 is set between the two, and they are connected by a first pin 4-5 and a second pin 4-6.

[0071] Specifically, a method for using a reinforcement and vibration damping device for the main structure of a steel pipe tower includes the following steps:

[0072] The transverse vibration damping components and the oblique vibration damping components are respectively installed at the fixed base of the reinforcing angle steel through universal joints. The segmented components and the reinforcing angle steel are fixed to the circumference of the steel pipe through the segmented components. The length is adjusted by rotating the connecting rod. The reinforcing angle steel, the segmented components and the steel pipe cooperate to form a new cross section, which increases the bearing area of ​​the original steel pipe and improves the ultimate bearing capacity and stability of the structure.

[0073] Two reinforcing angle steels are respectively installed on the back side of the four original structural steel pipes with corresponding reinforcing clamps. The support is equipped with universal joints and is linked with the transverse vibration damping components and the oblique vibration damping components. Axial dampers are installed at the first and second reinforcing clamps. One end of the first piston rod is connected to the threaded sleeve, and one end of the second piston rod is connected to the threaded sleeve.

[0074] Rotate the threaded sleeve to adjust the vibration damping range of the connecting rod in the axial length direction. The piston rod corresponding to the axial damper moves along its length direction to adjust the oil pressure in the inner cavity of the axial damper, thereby changing the damping force in the axial direction.

[0075] Moreover, the axial reinforcement components are located circumferentially on the steel pipe and connected to the support, increasing the load-bearing area of ​​the steel pipe and improving the structural strength of the steel pipe tower. Under load, the steel pipe tower effectively reduces its own vibration through the axial damping components, lateral damping components and oblique damping components.

[0076] Example 2

[0077] The difference between this embodiment and Embodiment 1 is that:

[0078] Axial reinforcement components are installed at all steel pipes at the set section of the steel pipe tower, and transverse vibration damping components and oblique vibration damping components are installed on each side of the steel pipe tower.

[0079] It is easy to understand that multiple reinforcement and vibration damping devices can be installed along the steel pipe tower.

[0080] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
