Description

Technical Field

[0001] The invention belongs to the technical field of communication iron towers, and in particular relates to an earthquake-resistant communication iron tower. Background Art

[0002] Communication towers are structures used to support wireless communication equipment, supporting the transmission of communication services such as mobile phone signals and wireless internet. They are typically constructed of steel. These towers typically feature multiple antennas and equipment mounting platforms, which are used to mount various communication equipment and provide communication services to the surrounding area. Communication towers play a vital role in modern society, providing convenient communication services.

[0003] The climbing ladder on the existing communication tower is an important channel for maintenance personnel to inspect the tower, install equipment and maintain the tower. The climbing ladder is usually fixed to the tower body by welding or bolts. This fixing method can ensure the normal use of the ladder under normal circumstances. However, when a natural disaster such as an earthquake occurs, due to the rigid connection between the ladder and the tower body, the earthquake will cause the tower body of the communication tower to deform, and the ladder is very likely to twist or break. This not only brings great difficulties to the maintenance personnel's climbing, but may even make the ladder impassable. After an earthquake, it is often necessary to restore communications in the disaster area as soon as possible to ensure rescue work and normal communication needs in the disaster-stricken area. If the communication tower cannot be repaired by the climbing ladder due to damage or change in angle, it will seriously affect the timeliness of communication restoration, which may have an adverse impact on the communication rescue work in the entire disaster area.

[0004] Therefore, it is urgent to provide an earthquake-resistant communication tower to solve the above problems. Summary of the Invention

[0014] Preferably, a sliding block is fixedly mounted on the other end of the first sleeve, a movable frame is slidably mounted on the outside of the sliding block, and the outside of the movable frame is in contact with the connecting horizontal rod and the connecting vertical rod.

[0015] Through the above technical solution, the connecting horizontal rods and the connecting vertical rods enable the movable frame to move accordingly, and the movable frame moves stably in the horizontal and vertical directions through the sliding blocks, thereby causing the movable frame to squeeze the first sleeve.

[0023] With the above technical solution, the double buffer connection is used to avoid rigid stress transmission, thereby ensuring the stability of the ladder mounting ring and the second climbing ladder and preventing them from twisting or breaking.

The second climbing ladder module is installed in combination, and the overall function will not be lost due to local damage to the climbing ladder. The climbing ladder as a whole can also support the partially damaged climbing ladder, so that the damaged climbing ladder can continue to be used, ensuring that personnel can safely climb the communication tower to perform equipment maintenance in an emergency. (2) The present invention is provided with an anti-seismic mechanism, so that when the second tower body is isolated and buffered by the isolation support, it will squeeze the moving frame through the outer frame, so that the moving frame can be buffered and shock-absorbing by the spring inside the square tube of the frame, forming a double-layer anti-seismic mechanism, which significantly reduces the impact of earthquakes on the communication tower.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present 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 only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figure 1-Figure 7 As shown, an earthquake-resistant communication tower of the present embodiment includes a first tower body 1 and a second tower body 2 fixed to the top of the first tower body 1, and an operating platform 3 is fixedly installed on the top of the second tower body 2; four connecting seats 4 are fixedly installed on the bottom end of the first tower body 1, and the bottom ends of the four connecting seats 4 are all fixed with seismic isolation supports 5, and the bottom ends of the four seismic isolation supports 5 are all fixed with mounting seats 6, and the bottom ends of the four mounting seats 6 are fixed with base plates 7, and the bottom ends of the base plates 7 are fixed with fixed plugs 8 extending into the ground; the top of the base plate 7 is provided with an earthquake-resistant mechanism 9 for reducing the impact of earthquakes on the communication tower through a double-layer earthquake-resistant mechanism, and the earthquake-resistant mechanism 9 includes a fixing seat 901 fixed to the top of the base plate 7, and the top of the fixing seat 901 is fixed with an end penetrating A first climbing ladder 902 passes through and extends to the interior of the first tower body 1, and an outer frame 903 is fixedly installed on the outside of the four connecting seats 4. A connecting cross bar 904 is fixed between the left and right sides of the inner cavity of the outer frame 903, and a connecting vertical bar 905 is fixed between the front and back sides of the inner cavity of the outer frame 903. When an earthquake occurs, the seismic wave is transmitted to the bottom of the communication tower, and the base plate 7 will be vibrated, and the transmission of part of the seismic energy will be weakened through the seismic isolation support 5. When the communication tower shakes through the seismic isolation support 5, the connecting seat 4 will drive the outer frame 903 to move accordingly, and the outer frame 903 will drive the connecting cross bar 904 and the connecting vertical bar 905 to move accordingly.

[0031] like Figure 3 and Figure 4 As shown, an inner square frame 906 is fixedly installed on the outside of the fixing seat 901, a frame square tube 907 is fixedly installed on the outside of the inner square frame 906, a first round rod 908 is fixedly installed on the inner wall of the frame square tube 907, a first spring 909 is sleeved on the outside of the first round rod 908, a first sleeve 910 is slidably installed between the frame square tube 907 and the first round rod 908, the two ends of the first spring 909 are fixedly connected to the inner wall of the frame square tube 907 and one end of the first sleeve 910 respectively, a first sealing ring 911 is fixedly installed on the outside of the first sleeve 910 and is sealed with the inner wall of the frame square tube 907, and the other end of the first sleeve 910 is fixedly installed The sliding block 912 has a moving frame 913 installed on the outside of the sliding block 912. The outside of the moving frame 913 fits with the connecting cross bar 904 and the connecting vertical bar 905. The connecting cross bar 904 and the connecting vertical bar 905 make the moving frame 913 move accordingly. The moving frame 913 moves stably in the horizontal and vertical directions through the sliding block 912, so that the moving frame 913 squeezes the first sleeve 910. Under the action of the seismic force, the first sleeve 910 will slide along the first round rod 908 and compress the first spring 909, thereby absorbing and buffering the seismic energy. The first sealing ring 911 prevents moisture and dust from entering the interior of the frame square tube 907.

[0032] like Figure 5-Figure 7 As shown, the interior of the second tower body 2 is provided with a climbing mechanism 10 to prevent the climbing ladder from twisting or breaking due to deformation of the tower body during an earthquake. The climbing mechanism 10 includes four tower body square tubes 1001 respectively fixed to the interior of the second tower body 2, and a second round rod 1002 is fixedly installed on the inner bottom wall of the tower body square tube 1001. A second spring 1003 is sleeved on the outside of the second round rod 1002. A second sleeve 1004 is slidably installed between the tower body square tube 1001 and the second round rod 1002. The two ends of the second spring 1003 are fixedly connected to the inner bottom wall of the tower body square tube 1001 and one end of the second sleeve 1004 respectively. When the tower body tilts or twists to one side, the second sleeve 1004 will slide in the tower body square tube 1001, compress the second spring 1003, and absorb part of the energy. The second sealing ring 1005 prevents moisture and dust from entering the interior of the tower body square tube 1001.

[0033] like Figure 6 and Figure 7As shown, the outside of the second sleeve 1004 is fixedly installed with a second sealing ring 1005 that is sealed and connected to the inner wall of the tower square tube 1001, and the other end of the second sleeve 1004 is fixedly installed with a ladder anti-seismic rod 1006, and the top of the ladder anti-seismic rod 1006 is fixedly installed with a ladder cylinder 1007, and the inner bottom wall of the ladder cylinder 1007 is fixedly installed with a third round rod 1008, and the outside of the third round rod 1008 is provided with a third spring 1009, and a third sleeve 1010 is slidably installed between the ladder cylinder 1007 and the third round rod 1008, and the two ends of the third spring 1009 are respectively fixedly connected to the inner bottom wall of the ladder cylinder 1007 and one end of the third sleeve 1010, and the outsides of the four third sleeves 1010 are fixedly installed with third sealing rings 1011 that are sealed and connected to the inner wall of the ladder cylinder 1007. A ladder mounting ring 1012 is fixedly installed on the other end of 1010, and a second climbing ladder 1013 is fixedly installed on the bottom end of the ladder mounting ring 1012. There are six climbing mechanisms 10, and a ladder connecting rod 1014 is fixedly installed between the ladder anti-seismic rods 1006 of the six climbing mechanisms 10. When the tower body tilts to one side or twists, the third sleeve 1010 will slide in the ladder cylinder 1007, compressing the third spring 1009, absorbing part of the energy, and avoiding rigid stress transmission through double buffer connection, thereby ensuring the stability of the ladder mounting ring 1012 and the second climbing ladder 1013 and preventing them from twisting or breaking. The ladder anti-seismic rods 1006 between multiple climbing mechanisms 10 are interconnected through the ladder connecting rod 1014 to form a stable whole, which further enhances the reliability of the climbing mechanism 10 in an earthquake environment.

[0034] The working principle of this embodiment is as follows: when an earthquake occurs, the seismic wave is transmitted to the bottom of the communication tower, the base plate 7 will be vibrated, and the transmission of part of the seismic energy will be weakened by the seismic isolation support 5. When the communication tower shakes through the seismic isolation support 5, the connecting seat 4 will drive the outer frame 903 to move accordingly, and the outer frame 903 will drive the connecting cross bar 904 and the connecting vertical bar 905 to move accordingly. The connecting cross bar 904 and the connecting vertical bar 905 make the moving frame 913 move accordingly. The moving frame 913 moves stably in the horizontal and vertical directions through the sliding block 912, thereby causing the moving frame 913 to squeeze the first sleeve 910. Under the action of the seismic force, the first sleeve 910 will slide along the first round rod 908 and compress the first spring 909, thereby absorbing and buffering the seismic energy. At the same time, when the tower body tilts to one side or twists, the second sleeve 1004 will move in the tower body square tube 1001 The third sleeve 1010 will slide inside the ladder cylinder 1007, compressing the third spring 1009 and absorbing part of the energy. The double buffer connection avoids rigid stress transmission, thereby ensuring the stability of the ladder mounting ring 1012 and the second climbing ladder 1013 and preventing them from twisting or breaking. During maintenance after an earthquake, the staff climbs the first tower body 1 area through the first climbing ladder 902 and climbs the second tower body 2 area through the combined second climbing ladder 1013. The combined second climbing ladders 1013 are connected to each other through the ladder anti-seismic rod 1006 and the ladder connecting rod 1014 to form a stable whole. The overall function will not be lost due to damage to a single second climbing ladder 1013, ensuring that the staff can safely climb the communication tower for equipment maintenance in an emergency.
