Description

Technical Field

[0001] This invention relates to the field of communication tower technology, specifically a wind-resistant and earthquake-resistant communication tower. Background Technology

[0002] A communication tower is a tall steel structure used to support communication antennas, transmission equipment and other ancillary facilities. Its main function is to provide sufficient coverage height and transmission path for wireless signals. It is widely used in mobile communications, broadcasting and television, radar monitoring and other fields. In order to ensure its long-term service performance in complex outdoor climate environments, the structural design, material selection and protection measures of the tower must meet strict technical standards.

[0003] Existing communication towers still have shortcomings in wind and earthquake resistance. Their joint structures are mostly rigid connections, lacking effective damping mechanisms, which can easily lead to weld cracking or bolt loosening. Wind-resistant measures often rely on increasing material usage or adding guy wires, but these guy wires are prone to significant swaying and vibration in strong winds, potentially leading to strand breakage or fracture due to dynamic fatigue. Furthermore, coordinating and controlling the pretension of multiple guy wires is difficult, and uneven slack or breakage can easily occur after long-term use. Summary of the Invention

[0004] The purpose of this invention is to provide a wind- and earthquake-resistant communication tower to solve the problem of inconvenience in using existing communication towers.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wind- and earthquake-resistant communication tower includes a support column and also includes:

[0007] The support column has a support plate on its exterior, multiple columns on the support plate, and a crossbeam on its exterior. The multiple columns and the crossbeam form the external frame of the communication tower. The support column has a support plate on its exterior, and an installation groove is provided inside the support plate. A connecting block is provided inside the installation groove. A fixing block is provided at one end of the connecting block. A support sleeve is rotatably provided on the side wall of the fixing block. A telescopic plate is provided at one end of the support sleeve. A pad that contacts the exterior of the support column is provided on the telescopic plate. A support member is provided at the other end of the connecting block. The support member includes a movable rod and a sleeve. A connecting spring is provided inside the sleeve. Both ends of the connecting spring are connected to the movable rod.

[0008] The rotating plate has a transmission plate inside the mounting groove. One end of the transmission plate has a groove that mates with the support sleeve, and the other end of the transmission plate has a pull rope. The bottom of the support column has a fixed plate, and the outside of the fixed plate has a telescopic plate and a movable plate. One end of the movable plate has a support block, and the inside of the support block has a guide wheel. The telescopic plate has a rotating wheel, and the pull rope passes through the guide wheel and the rotating wheel in sequence. The sleeve has a rotating plate inside, and the pull rope has a fixed post that mates with the rotating plate.

[0009] A fixing mechanism, located at the bottom of the fixing plate, is used to fix the movable plate and the telescopic plate.

[0010] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0011] In one alternative embodiment: the fixing mechanism includes an adjusting plate, a pressure block, and a fixing plate. The adjusting plate is provided at the bottom of the fixing plate, and multiple fixing plates are provided at the bottom of the adjusting plate. A pressure block is provided at one end of the movable plate that penetrates into the interior of the fixing plate. A transmission column is provided at the top of the fixing plate, and one end of the transmission column is in contact with the pressure block.

[0012] In one alternative: the inner wall of the fixed plate is provided with a support frame, the support frame is provided with gears, and the movable plate and the telescopic plate are both provided with gear grooves on the side that are close to each other, and the gears mesh with the gear grooves on the upper and lower sides.

[0013] In one alternative: the sleeve is provided with a locking screw, the sleeve is provided with a rotating shaft, and the rotating plate is fixedly mounted on the rotating shaft.

[0014] In one alternative: a protective plate is provided on the outside of the telescopic plate and the movable plate, and a base plate is provided at the bottom of the protective plate, with multiple mounting holes provided on the base plate.

[0015] In one alternative: a support rod is provided at the connection point of the crossbeam, and a fixing ring is provided on the outside of the support column.

[0016] In one alternative: one end of the support rod is connected to a fixing ring, and the fixing ring is fixed to the outside of the support column by bolts.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The wind- and earthquake-resistant communication tower integrates flexible traction with rigid support. Under normal use, the support is a flexible chain. The swaying of the support column is transmitted to the flexible chain arranged around it through the pads. The spring can efficiently absorb and dissipate vibration energy, converting large swings into small-amplitude reciprocating motions, thereby effectively reducing the dynamic response of the tower. When encountering strong winds that cause the tower to shift laterally beyond a certain value, the fixed column on the rope squeezes the rotating plate inside the sleeve, causing it to rotate rapidly and lock the movable rods on both sides. This instantly transforms the originally flexible energy-dissipating chain into a rigid support truss, providing strong lateral support for the tower, limiting its further deformation, and effectively preventing structural instability.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0034] like Figure 1-12 As shown, a wind-resistant and earthquake-resistant communication tower according to an embodiment of the present invention includes a support column 1, and further includes:

[0035] The support column 1 is externally supported by a support plate 2, which serves as the central support of the entire tower. Multiple columns 3 are mounted on the support plate 2. The tops of the columns 3 are used to install the tower top platform and various communication equipment, including antennas for receiving and transmitting wireless signals, radio frequency units for signal processing, and lightning protection devices. A crossbeam 4 is externally mounted on the columns 3, forming a spatial truss-type external support frame that collectively bears the external load. A support plate 12 is externally mounted on the support column 1, with an installation groove 121 inside. Multiple connecting blocks 13 are slidably mounted within the installation groove 121, and their sliding positions can be adjusted as needed. After adjustment, they are fixed by fastening bolts. A fixing block 16 is fixedly mounted at one end of each connecting block 13. A support sleeve 24 is rotatably mounted on the side wall of the fixing block 16. Two support sleeves 24 are inclined and symmetrical. A telescopic plate 25 is mounted on the end of the support sleeve 24 away from the fixing block 16 via elastic elements such as compression springs, allowing for telescopic movement. The plate 25 has a certain telescopic buffering capacity. A pad 26 is fixedly installed at the end of the telescopic plate 25. The pad 26 keeps in contact with the outer wall of the support column 1, thereby forming an elastic auxiliary support for the support column 1. A support member is provided at the other end of the connecting block 13. The support member includes a movable rod 8 and a sleeve 9. One end of the movable rod 8 extends into the sleeve 9 and can move. A connecting spring 29 is installed inside the sleeve 9. The two ends of the connecting spring 29 are respectively connected to the ends of the two movable rods 8 that extend into the sleeve 9. Multiple sleeves 9 are connected to the movable rods 8 in sequence to form a flexible connecting chain that pulls the connecting block 13. When the tower sways due to wind, the displacement of the support column 1 will be transmitted through the pad 26, causing the movable rod 8 and the sleeve 9 to move relative to each other, thereby compressing or stretching the connecting spring 29. The connecting spring 29 absorbs and dissipates the kinetic energy of the structural vibration through its elastic deformation, transforming the large-amplitude violent swaying into a small-amplitude reciprocating damping motion, thereby playing a buffering and shock absorption role.

[0036] The rotating plate 32 has a transmission plate 27 inside the mounting groove 121. Two transmission plates 27 form a group and are connected by a pull rope 10. The pull rope 10 passes through the central through hole of the series-connected sleeves 9 and the movable rod 8. One end of the transmission plate 27 has a groove 271 that matches the outer contour of the support sleeve 24, and the other end is fixedly connected to the end of the pull rope 10. The bottom of the support column 1 is provided with a fixed plate 6. The fixed plate 6 is provided with a telescopic plate 20 and a movable plate 19. One end of the movable plate 19 is provided with a support block 11. The support block 11 is provided with a guide wheel 30. The telescopic plate 20 is provided with a rotating... The central part of the pull rope 10 is wound around the rotating wheel 28, with its two ends extending horizontally outwards. It passes sequentially around the guide wheel 30, through the connected movable rod 8 and sleeve 9, and finally connects to the transmission plate 27. When the support column 1 tilts significantly to one side due to wind force, the two pads 26 on that side will move accordingly, pushing the two sets of support sleeves 24 connected to it to tilt. The tilting of the support sleeves 24, through the groove 271, causes the two transmission plates 27 to move in opposite directions, thereby pulling the two ends of the pull rope 10 connected to it, causing the two pull ropes 10 passing through the same sleeve 9 to produce relative movements in opposite directions (as shown in the image). Figure 12 As shown), the fixed column 31 presses against the rotating plate 32, forcing the rotating plate 32 to rotate around its hinge point. During the rotation, the two ends of the rotating plate 32 press against the two movable rods 8 inside the sleeve 9, locking the movable rods 8, which were originally able to slide relative to each other, and the sleeve 9 into a rigid whole. This quickly transforms the originally flexible support chain into a rigid support truss, providing strong instantaneous lateral support for the tilted support column 1, effectively limiting its further tilting, and also preventing the pull rope 10 from being damaged by excessive tension under abnormal conditions, thus improving the safety of the system.

[0037] A fixing mechanism is provided at the bottom of the fixing plate 6, which can fix the movable plate 19 and the telescopic plate 20.

[0038] like Figure 1-10As shown, in a preferred embodiment of the present invention, the fixing mechanism includes an adjusting plate 5, a pressure block 191, and a fixing plate 17. The adjusting plate 5 is provided at the bottom of the fixing plate 6, and multiple independently adjustable fixing plates 17 are evenly connected around the bottom of the adjusting plate 5 to form an adjustable foundation support. A wedge-shaped pressure block 191 is provided at one end of the movable plate 19 that penetrates into the interior of the fixing plate 6. A transmission column is vertically provided at the top of the fixing plate 17, and the top of the transmission column is in contact with the bottom surface of the pressure block 191. The adjusting plate 5 and the fixing plate 6 are installed on the foundation as a support base. The horizontal position of the pressure block 191 is changed by adjusting the radial position of each movable plate 19 according to the actual ground conditions. Since the bottom of the pressure block 191 is machined with an inclined slope, when it moves horizontally, it presses the top of the transmission column that it contacts through the inclined slope, thereby driving the corresponding fixed plate 17 to move vertically. By adjusting the position of multiple movable plates 19, the support height of each fixed plate 17 can be controlled, so that the upper adjustment plate 5 and fixed plate 6 are kept in a horizontal state, ensuring the initial installation verticality of the support column 1.

[0039] like Figure 1-7 As shown, in a preferred embodiment of the present invention, a support frame 22 is provided on the inner wall of the fixed plate 6, and a gear 23 is provided on the support frame 22. A gear groove 21 is provided on the side of the movable plate 19 that is close to the telescopic plate 20. The gear 23 meshes with the gear grooves 21 on the upper and lower sides. When it is necessary to tension the pull rope 10, multiple movable plates 19 are driven to move horizontally. The meshing transmission between the gear 23 and the upper and lower gear grooves 21 converts the horizontal movement of the movable plate 19 into the horizontal movement of the telescopic plate 20 in the opposite direction, so that the rotating wheel 28 and the guide wheel 30 installed on it move away from each other, thereby tightening the pull rope 10 wrapped between them.

[0040] like Figure 1-11 As shown, in a preferred embodiment of the present invention, the sleeve 9 is provided with a locking screw 901, the sleeve 9 is provided with a rotating shaft 33, and the rotating plate 32 is fixedly mounted on the rotating shaft 33.

[0041] like Figure 1-4 As shown, in a preferred embodiment of the present invention, a protective plate 7 is provided on the outside of the telescopic plate 20 and the movable plate 19, and a base plate 18 is provided at the bottom of the protective plate 7. The base plate 18 has multiple mounting holes to facilitate fixing to the foundation or concrete foundation.

[0042] like Figure 1-2As shown, in a preferred embodiment of the present invention, a support rod 15 is provided at the connection point of the crossbeam 4, and a fixing ring 14 is provided on the outside of the support column 1. One end of the support rod 15 is connected to the fixing ring 14, and the fixing ring 14 is fixedly installed on the outside of the support column 1 by bolts. This connects the outer frame to the central support column 1 at multiple points, forming a composite structural system with coordinated internal and external forces, thereby improving the overall lateral stiffness and stability of the tower.

[0043] The above embodiments of the present invention provide a wind- and earthquake-resistant communication tower. A base plate 18 is fixed to the ground through mounting holes. A fixing plate 6 and an adjusting plate 5 are installed. The radial positions of each movable plate 19 are adjusted sequentially. When a movable plate 19 moves, the inclined groove at the bottom of the pressure block 191 at its end presses against the transmission column at the top of the fixing plate 17, thereby driving the corresponding fixing plate 17 to rise and fall vertically. Each movable plate 19 is repeatedly adjusted until the bottom of all fixing plates 17 is in full contact with the uneven ground. The upper surface of the fixing plate 6 is adjusted to a horizontal state. A support plate 12 is fitted over the support column 1. A connecting block 13 is inserted into the mounting groove 121 of the support plate 12. A fixing block 16, a support sleeve 24, and a telescopic plate 25 with pads 26 are connected. Multiple pads... Block 26 maintains contact with the outer wall of the support column 1, locking the connecting block 13, and sequentially hinges the movable rod 8 and the sleeve 9 with the built-in connecting spring 29 into a chain. The central part of the pull rope 10 is wound around the rotating wheel 28 of the telescopic plate 20. The two ends of the pull rope 10 pass through the guide wheel 30, the central through hole of each sleeve 9 and the movable rod 8 in sequence, and finally connect to the transmission plate 27, uniformly tightening the entire pull rope 10 system. Communication antennas, radio frequency units, feeders and lightning rods are installed on the platform. When the support column 1 is subjected to wind force and produces a large lateral displacement, the transmission plate 27 pulls the pull rope 10, and the movable rod 8 and the sleeve 9, which can slide relative to each other, are locked into a rigid whole, transforming the originally flexible support chain into a rigid support truss, providing lateral support for the inclined support column 1.

[0044] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
