Description

Technical Field

[0001] This utility model relates to the field of damping technology for tall structures such as iron towers, and particularly to a damping device and an iron tower including the damping device. Background Technology

[0002] Transmission line towers and mobile communication towers are generally referred to as tall structures. Tall structures are those with relatively large height and small cross-section. Their structural forms can be divided into self-supporting tower structures and guyed mast structures, hence the name tower-mast structures. Taking transmission towers as an example, their structural characteristics are that all tower types are space truss structures. The members are mainly composed of single equilateral angle steel or combined angle steel. The members are connected by coarse bolts, which are connected by shear force. The entire tower is composed of angle steel, connecting steel plates, and bolts. Some components, such as the tower feet, are made by welding several steel plates into a single assembly. This makes the tower extremely convenient for transportation and construction.

[0003] Since most transmission towers are located in the field, strong winds have a significant impact on their safety. Typhoons, as a highly destructive natural disaster, pose a huge threat to the safe operation of transmission line tower systems. At best, they cause repeated vibrations to the towers, loosening bolts and other connecting structures and affecting the stability of the tower structure. At worst, they exert significant stress on the towers, causing them to sway, or even twist or break.

[0004] To mitigate the impact of severe winds such as typhoons, most current methods employ a mass pendulum suspension system on steel towers for vibration damping. While this damping device is simple in structure and easy to install, the weight of the pendulum itself causes the tower to bear its own weight for extended periods. This leads to stress concentration within the tower's internal structure, resulting in deformation under prolonged stress and hindering the tower's long-term use. Furthermore, during strong typhoons, the pendulum's excessive swing amplitude inevitably causes collisions with the tower, damaging its structure. Utility Model Content

[0007] The damping device described above, preferably, further includes: There are multiple rotating shafts, each of which is rotatably mounted on the iron tower; At least one of the rotating wheels is provided on each of the rotating shafts; Each of the rotating shafts is fixed with a swing arm, one end of which is fixed to the rotating shaft, and the axis of the swing arm is perpendicular to the axis of the rotating shaft.

[0008] The damping device described above, preferably, further includes a return spring, which is connected at least between the two of the rocker arms.

The rotating wheel also includes an upper front rotating wheel and an upper rear rotating wheel, which are respectively arranged on the front and rear sides of the upper rotating shaft. One of the upper front rotating wheel and the upper rear rotating wheel is fixed on the upper rotating shaft, and the other is rotatably arranged on the upper rotating shaft. The swing arm also includes an upper swing arm, which is fixed to the middle of the upper rotating shaft. The upper swing arm extends downwards, and a damper is connected to each of the left and right sides of the upper swing arm.

[0010] As described above, the damping device preferably includes a lower left rotating shaft among the plurality of rotating shafts. The lower left rotating shaft is disposed at the lower left part of the tower, extends along the left-right direction of the tower, and is disposed at the middle part of the tower in the front-back direction.

[0011] As described above, the damping device preferably includes a lower right rotating shaft among the plurality of rotating shafts. The lower right rotating shaft is located at the lower right part of the tower, extends along the left-right direction of the tower, and is located at the middle of the front-back direction of the tower. The rotating wheel also includes a lower right rotating wheel, which is fixedly mounted on the right side of the lower right rotating shaft; The swing arm also includes a lower right swing arm, which is fixed to the left side of the lower right pivot.

[0015] This utility model also provides a steel tower, including a shock absorption device, wherein the shock absorption device is the aforementioned damping device.

[0016] Compared with the closest existing technology, the technical solution of this utility model embodiment has the following beneficial effects: In this damping device, when the tower deforms under external force, the relative positions of the rotating wheels change. Through the transmission between the transmission components and the rotating wheels, the wheels rotate, and the pendulum swings under their influence. This swinging motion compresses or stretches the damper, allowing it to absorb energy and reduce vibration, thus reducing the tower's sway and improving its stability. When the pendulum swings off-center, the return spring deforms, also acting as an energy-absorbing unit. After the typhoon ends and the tower is no longer affected by external wind forces, the return spring gradually returns to its original shape, causing the pendulum to return to its original position, bringing the tower to a balanced state.

[0017] Furthermore, since this damping device completely abandons the technical concept of using a mass pendulum, and the weight of the rotating wheel, transmission components, pendulum rod, and damper in this damping device is much smaller than the weight of a traditional mass pendulum, the impact of the weight of this damping device on the tower is greatly reduced, which is conducive to improving the service life of the tower.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] According to specific embodiments of this utility model, such as Figure 1-4 As shown, this utility model provides a steel tower including a damping device, wherein the damping device includes: There are multiple rotating wheels, each of which is mounted on the iron tower.

[0022] A transmission component, wherein the transmission is arranged between at least a plurality of rotating wheels.

[0023] The pendulum has multiple arms, which rotate synchronously when the wheel rotates.

[0024] Dampers 3 are provided in multiples, and each pendulum is connected to at least one damper 3. One end of the damper 3 is hinged to the iron tower, and the other end is hinged to the pendulum.

[0025] In this damping device, under the action of a typhoon, the iron tower will sway or twist. Due to the deformation of the iron tower itself, the relative position between the rotating wheels changes. Under the transmission action between the transmission component and the rotating wheels, the rotating wheels will rotate, and the swing rod will swing under the drive of the rotating wheel. The swing of the rotating rod will compress or stretch the damper 3, so that the damper 3 can play the role of energy dissipation and shock absorption, reduce the sway of the iron tower itself, and improve the stability of the iron tower.

[0026] Moreover, since the damping device completely abandons the technical concept of using a mass pendulum, and the weight of the rotating wheel, transmission components, pendulum rod and damper 3 in the damping device is much smaller than the weight of a traditional mass pendulum, the impact of the weight of the damping device on the tower is greatly reduced, which is conducive to improving the service life of the tower.

[0027] The damping device also includes multiple rotating shafts, each rotatably mounted on the tower; each rotating shaft has at least one wheel; and each rotating shaft has a fixed pendulum rod, one end of which is fixed to the rotating shaft, and the axis of the pendulum rod is perpendicular to the axis of the rotating shaft.

[0028] In this embodiment, a bearing seat 1 is provided at both ends of each rotating shaft. The bearing seat 1 is fixed on the iron tower, and the end of the rotating shaft is rotatably mounted on the bearing seat 1, so that the rotating shaft can rotate stably towards the iron tower.

[0029] In this embodiment, the wheel and the shaft can be connected by a key, or the wheel can be directly welded to the shaft. There are no specific restrictions on the fixed connection method between the two.

[0030] In this embodiment, one end of the swing arm can be connected to the pivot shaft by bolts or by direct welding. There are no specific restrictions on the fixed connection method between the two.

[0031] In this embodiment, the swing arm includes an upper swing arm 2, a lower left swing arm 12, and a lower right swing arm 7, and the structures of the upper swing arm 2, the lower left swing arm 12, and the lower right swing arm 7 are all identical; for example Figure 4 As shown, the two sides of the swing arm are symmetrically arranged with protrusions to form a cross structure. This arrangement allows the swing arm to be hinged to the damper through the protrusions on both sides.

[0032] The damping device also includes a return spring 4, which is connected between at least two swing arms. In this embodiment, when the swing arms swing, the return spring 4 deforms, and at this time, the return spring 4 also acts as an energy-dissipating unit, playing a role in shock absorption and energy dissipation. When the typhoon ends, the tower itself is no longer affected by external wind force, and the return spring 4 gradually returns to its original shape, thereby driving the swing arms to return to their original position, so that the tower is in a balanced state.

[0033] The multiple rotating shafts include an upper rotating shaft 16, which is located on the upper part of the iron tower and extends along the front-to-back direction of the iron tower. The upper rotating shaft 16 is also located in the middle of the iron tower in the left-to-right direction. The rotating wheels also include an upper front rotating wheel 15 and an upper rear rotating wheel 17, which are respectively located on the front and rear sides of the upper rotating shaft 16. One of the upper front rotating wheel 15 and the upper rear rotating wheel 17 is fixed on the upper rotating shaft 16, and the other is rotatably mounted on the upper rotating shaft 16. The swing arm also includes an upper swing arm 2, which is fixed in the middle of the upper rotating shaft 16 and extends downward. A damper 3 is connected to each of the left and right sides of the upper swing arm 2.

[0034] In this embodiment, one of the upper front rotating wheel 15 and the upper rear rotating wheel 17 is fixed on the upper rotating shaft 16, and the other is rotatably mounted on the upper rotating shaft 16, so as to ensure that the rotating shaft is driven by only one rotating wheel, thereby avoiding the situation where the two rotating wheels interfere with each other due to opposite rotation directions.

[0035] In this embodiment, when the upper rotating shaft 16 drives the upper swing rod 2 to swing in the left and right directions, one damper 3 connected to the upper swing rod 2 is stretched and the other damper 3 is compressed, so that the two dampers 3 can play the role of shock absorption and energy dissipation at the same time.

[0036] In this embodiment, the damper 3 is a hydraulic damper 3, a gas damper 3, or other structures.

[0037] The multiple rotating shafts also include a lower left rotating shaft 10, which is located at the lower left part of the tower. The lower left rotating shaft 10 extends along the left and right direction of the tower and is located at the middle of the front and back direction of the tower. The rotating wheel also includes a lower left rotating wheel 11, which is fixedly located on the left side of the lower left rotating shaft 10. The swing arm also includes a lower left swing arm 12, which is fixed on the right side of the lower left rotating shaft 10. The lower left swing arm 12 extends upward and is connected to a damper 3 on the front and back sides of the lower left swing arm 12 respectively.

[0038] In this embodiment, when the lower left pivot 10 drives the lower left swing arm 12 to swing in the front-back direction, one damper 3 connected to the lower left swing arm 12 is stretched and the other damper 3 is compressed, so that the two dampers 3 can play the role of shock absorption and energy dissipation at the same time.

[0039] In this embodiment, the axis of the lower left rotating shaft 10 is perpendicular to the axis of the upper rotating shaft 16, causing the upper swing arm 2 to swing in the left and right directions and the lower left swing arm 12 to swing in the left and right directions. This allows the damping device to play a role in shock absorption and energy dissipation in different directions of the tower, so as to ensure that the tower as a whole can achieve a better damping and energy dissipation effect.

[0040] The multiple rotating shafts also include a lower right rotating shaft 9, which is located at the lower right part of the tower. The lower right rotating shaft 9 extends along the left and right direction of the tower and is located in the middle of the front and back direction of the tower. The rotating wheel also includes a lower right rotating wheel 8, which is fixedly located on the right side of the lower right rotating shaft 9. The swing arm also includes a lower right swing arm 7, which is fixedly located on the left side of the lower right rotating shaft 9. The lower right swing arm 7 extends upwards and is connected to a damper 3 on its front and rear sides respectively.

[0041] In this embodiment, when the lower right pivot 9 drives the lower right swing arm 7 to swing in the front-to-back direction, one damper 3 connected to the lower right swing arm 7 is stretched and the other damper 3 is compressed, so that the two dampers 3 can play the role of shock absorption and energy dissipation at the same time.

[0042] In this embodiment, the lower right rotating shaft 9 is located to the right of the lower left rotating shaft 10, and the axis of the lower right rotating shaft 9 is on the same straight line as the axis of the lower left rotating shaft 10. The axis of the lower right rotating shaft 9 is perpendicular to the axis of the upper rotating shaft 16. This arrangement ensures that the lower left rotating shaft 10 and the lower right rotating shaft 9 are symmetrically arranged on both sides of the upper rotating shaft 16, which ensures that the entire damping device is symmetrically arranged in the tower. This allows the damping device to exert a more uniform damping effect on the tower, ensuring that the tower receives a more uniform damping force, and enabling the damping device to achieve a better damping effect.

[0043] The sprocket is a rotating wheel. In this embodiment, the sprocket is a rotating wheel, and the transmission component includes a chain, wherein the sprocket and the chain mesh with each other for transmission.

[0044] In other embodiments, the pulley can also be a synchronous pulley, in which case the transmission component includes a synchronous belt, and the synchronous pulley and the synchronous belt are connected to each other for transmission.

[0045] The transmission component includes multiple chain segments 14 and multiple connecting segments 13. The chain segments 14 mesh with sprockets for transmission, and the connecting segments 13 are respectively connected to the two ends of adjacent chain segments 14; and the multiple chain segments 14 and the multiple connecting segments 13 are interconnected to form a closed loop.

[0046] In this embodiment, the upper front wheel 15, upper rear wheel 17, lower left wheel 11, and lower right wheel 8 are connected in series by a transmission component, so that multiple wheels are connected to a closed-loop transmission component. This allows the transmission component to drive multiple wheels to rotate synchronously. As a result, when a typhoon occurs, all dampers 3 in the damping device can act as damping devices simultaneously, enabling the damping device to more efficiently reduce vibration and dissipate energy for the tower, ensuring that the tower can more efficiently restore its stability during a typhoon.

[0047] In this embodiment, the transmission component includes multiple chain segments 14 and multiple connecting segments 13. The chain segments 14 are made of chain, and the connecting segments 13 are made of steel cable, which can further reduce the manufacturing cost of the damping device.

[0048] Multiple fixed pulleys 6 are provided on the connecting section 13 of the transmission component on the iron tower, which are used for the connecting section 13 to pass through the fixed pulleys 6 and play a tensioning and guiding role for the connecting section 13.

[0049] In this embodiment, by setting a fixed pulley 6, the connecting section 13 in the transmission component is tensioned, so that the transmission component is in a tensioned state, thereby making the transmission between the transmission component and the rotating wheel more efficient, so that the damping device can exert its damping effect more quickly when a typhoon arrives.

[0050] The upper end of the return spring 4 is connected to the lower end of the upper swing arm 2. The lower end of the return spring 4 is connected to the upper end of the lower left swing arm 12 by a connecting rope 5. The lower end of the return spring 4 is also connected to the upper end of the lower right swing arm 7 by a connecting rope 5.

[0051] In this embodiment, the swing of the upper swing arm 2, the lower left swing arm 12, and the lower right swing arm 7 are not in the same plane. When the strong wind stops, the upper swing arm 2, the lower left swing arm 12, and the lower right swing arm 7 are restored to their original positions by the reset action of the reset spring 4, so as to ensure that the tower is in a balanced state.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
