Description

Technical Field

[0001] This invention relates to the field of communication tower technology, and in particular to a communication tower. Background Technology

[0002] Communication towers are an important component of wireless communication systems, used to mount antennas and relay and cover signals. To ensure the daily maintenance, inspection, and equipment installation of towers, structures such as ladders or climbing platforms are usually provided on the outside for maintenance personnel to climb. Because communication towers are generally quite tall, maintenance personnel face the dual safety risks of working at height and strong winds during the climbing process.

[0003] Existing communication towers are typically equipped with only simple ladders, rest platforms, and fixed fall arrest rails or safety ropes. While these structures provide some climbing conditions and fall protection, they cannot effectively withstand the direct impact of strong winds on workers. Especially in high-altitude areas or during certain seasons, wind speeds vary greatly at different heights of the tower, with sudden gusts frequently occurring in the upper and middle sections. This poses a serious safety threat to workers, easily leading to instability, collisions, and even falls from height. Currently, there is a lack of tower structures capable of intelligently and dynamically providing targeted wind protection for workers based on real-time wind conditions. Summary of the Invention

[0004] The purpose of this invention is to provide a communication tower to solve the technical problems mentioned in the background art.

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

[0006] A communication tower includes a tower body with an equipment room and climbing platforms arranged along the outer wall of the tower body. Multiple climbing ladders are evenly spaced on the climbing platforms, and a following rope connection structure for connecting safety belts is also provided on the climbing platforms. The tower also includes multiple segmented climbing windbreak mechanisms and a windbreak control module. The multiple segmented climbing windbreak mechanisms are arranged along the height direction of the tower body and include a ring frame and two telescopic windbreak structures. The ring frame is fitted around and fixedly connected to the outside of the tower body, and at least one wind sensor is installed on it. The two telescopic windbreak structures are arranged along the edges of the climbing platforms, and their tops are connected to the ring frame and can extend and retract along the height direction of the climbing platforms. When extended, the retractable windbreak structure forms a windproof passage for personnel to climb. The windbreak control module is located in the machine room of the tower and is communicatively connected to the ring platform and retractable windbreak structure in each segmented climbing windbreak mechanism. It is configured to: receive real-time outdoor wind force data and height location information sensed by the wind force sensor; analyze and determine whether the wind force at the corresponding height location poses a safety threat to the workers based on the wind force data, height location information, and wind force safety threshold model; when a safety threat is determined to exist, a control command is sent to the corresponding retractable windbreak structure, which switches from the retracted state to the extended state.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0008] In one alternative embodiment: the retractable windbreak structure includes an extendable folding plate unit and a scissor-type adjustment unit.

A post is provided at the bottom of the scissor-type adjustment unit. The ring frame is provided with a slot portion, and the slot portion corresponds to the post located above. When the extendable folding plate unit is fully extended, the post is inserted into the corresponding slot portion.

[0009] In one alternative embodiment: the scissor lift adjustment unit includes an extension / retraction cylinder and multiple scissor lift assemblies. Adjacent scissor lift assemblies are connected together by two movable joints. A cross pin is provided at the intersection of the scissor lift assemblies. A sleeve is fixedly connected to the cross pin and the sleeve is rotatably connected to the corresponding connecting shaft. The extension / retraction cylinder is fixed on the ring frame, and its extension / retraction end is connected to the cross pin in the uppermost scissor lift assembly. Two upper connecting seats are provided at the top of the uppermost scissor lift assemblies and the upper connecting seats are slidably connected to the ring frame.

[0010] In one alternative: the outer side of the tower body is also provided with a plurality of external support rods distributed along the circumference. The side walls of the external support rods are all fixedly connected to the outer walls of each ring frame through diagonal web members. The top of the external support rods is connected to the top of the tower body, and the bottom of the external support rods is provided with tower feet and fixed to the ground through anchor bolts.

[0011] In one alternative embodiment: the climbing platform surface is provided with a check groove along its height direction, and anti-fall teeth are evenly distributed on both side walls of the check groove; the following rope connection structure includes a hollow follower seat, a hook connector, and two side inclined blocks; the hollow follower seat is slidably disposed inside the check groove, and its side walls are open; the two side inclined blocks are installed inside the hollow follower seat and can move along the width direction of the check groove at the openings; a switching wedge is provided between the two side inclined blocks, and the switching wedge can move along the depth direction of the check groove inside the hollow follower seat. The two inclined blocks are connected by a compression spring. The contact between the side wall of the switching wedge and the side of the inclined block facing the interior of the hollow follower seat is an inclined surface contact. One end of the switching wedge extends to the outer surface of the hollow follower seat. The hook connector is rotatably disposed on the outer surface of the hollow follower seat and is used to connect with the hook of the seat belt. The hook connector is connected to the end of the switching wedge extending to the outer surface of the hollow follower seat. When the hook acts on the hook connector, the hook connector rotates to drive the switching wedge to move toward the interior of the hollow follower seat.

[0012] In one alternative: the end of the switching wedge extending to the surface of the hollow follower seat is provided with a stop plate; the hook connector includes a hook shaft, a hook body rod, and a cam part; the two ends of the hook shaft are rotatably mounted on the end face of the hollow follower seat through bearing seats; the cam part is fixed on the hook shaft, and its sidewall contacts the stop plate; the hook body rod is fixedly connected to the hook shaft and is used to fasten together with the hook of the safety rope.

[0013] In one alternative embodiment: the climbing ladder structure includes a U-shaped fixed rod, a movable sleeve, and a blocking block.

A rear extension frame and a front extension frame are fixed on the outer wall of the movable sleeve. The rear extension frame and the front extension frame are on the same plane. The blocking block is fixed on the end face of the climbing platform. When the front extension frame is in a horizontal state and facing the climbing platform, the end of the front extension frame away from the blocking block abuts against the lower surface of the blocking block.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects:

[0015] This invention utilizes windbreak mechanisms equipped with wind sensors at different heights within the tower, along with a windbreak control module. The system can perceive the actual wind force at each height level in real time. Through analysis and judgment, the windbreak channel automatically activates only in sections where wind force poses a safety threat, achieving precise and intelligent wind protection. This avoids the cost waste and obstruction of vision and ventilation caused by fixed shielding throughout the entire structure. When wind force exceeds the limit at a specific height, the retractable windbreak structure automatically extends, forming a continuous windbreak channel next to the climbing platform. This effectively resists the direct impact of strong lateral winds on maintenance personnel, significantly reducing the risk of instability and falls caused by strong winds at high altitudes, and providing physical wind barrier protection for climbing operations. The segmented design and retractable windbreak structure allow the windbreak structure to be in a retracted state when there is no wind or the wind force is low, without affecting the overall appearance of the tower, wind load, or the normal climbing vision and operation of maintenance personnel. It can be quickly deployed only when needed, achieving "unimpeded in normal times, protection in emergencies." The system can respond to different wind conditions at different heights, allowing maintenance personnel to safely carry out climbing operations under a wider range of wind speeds, reducing operation delays caused by weather, and enhancing the maintainability and adaptability of communication towers in complex weather environments.

Detailed Implementation

[0027] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0028] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0029] In one embodiment, such as Figures 1-4As shown, a communication tower includes a tower body 100 with an equipment room and climbing platforms 200 arranged along the outer wall of the tower body 100. Multiple climbing ladder structures 400 are evenly spaced on the climbing platforms 200, and a following rope connection structure 800 for connecting safety belts is also provided on the climbing platforms 200. It also includes multiple segmented climbing windbreak mechanisms and windbreak control modules. The multiple segmented climbing windbreak mechanisms are arranged along the height direction of the tower body 100, each including a ring frame 500 and two telescopic windbreak structures 700. The ring frame 500 is fitted around and fixedly connected to the outside of the tower body 100, and at least one wind sensor 600 is installed on it. The two telescopic windbreak structures 700 are arranged along the edge of the climbing platforms 200, and their tops are connected to the ring frame 500 and can be extended along the climbing platform. The climbing platform 200 extends and retracts in height, and the two retractable windbreak structures 700 form a windproof passage for personnel to climb when extended. The windbreak control module is located in the machine room of the tower body 100. It is communicatively connected to the ring platform 500 and the retractable windbreak structure 700 in each segmented climbing windbreak mechanism, and is configured to: receive real-time outdoor wind force data and height location information sensed by the wind force sensor 600; analyze and determine whether the wind force at the corresponding height location poses a safety threat to the workers based on the wind force data, height location information, and wind force safety threshold model; when a safety threat is determined to exist, a control command is issued to the corresponding retractable windbreak structure 700, and the retractable windbreak structure 700 switches from the retracted state to the extended state.

[0030] In this embodiment of the invention, when maintenance is carried out at a height of 100 meters on the tower body and workers need to climb, one end of the worker's safety belt is connected to a following rope connection structure 800. The following rope connection structure 800 can move with the worker along the height direction of the climbing platform 200, improving safety during the climb in case of a fall. When the worker climbs along the climbing platform 200, the wind force sensors 600 in each segmented climbing wind shield mechanism sense the wind force in real time at each height position to generate wind force data. The wind force data is transmitted to the wind shield control module. Based on the wind force data and the height position of the wind force sensors 600, the wind shield control module analyzes and determines whether the wind force at the corresponding height position poses a safety threat to the worker. If a safety threat exists, the wind shield control module sends a control command to the telescopic windbreak structure 700 at the corresponding height. The telescopic windbreak structure 700 switches from a retracted state to an extended state, and the two telescopic windbreak structures 700 are positioned at the climbing platform 200. The windproof channels formed on both sides can reduce the impact of strong winds on the workers' bodies, prevent them from being blown off the ladder, reduce fear and physical exertion, and effectively protect the safety of the workers. If the wind force is small and does not pose a safety hazard, the windproof cover control module sends a control command to the corresponding height of the telescopic windproof structure 700. The telescopic windproof structure 700 switches from the extended state to the retracted state, retracting to the lower surface of the corresponding ring frame 500. This reduces the stress surface of the entire tower 100, and the workers have a relatively wide field of vision, making it easier to observe the surrounding environment, antenna and equipment layout, and avoids stuffiness. The segmented climbing windproof cover mechanism can form windproof channels to reduce the danger of wind to construction workers when climbing, and also avoid increasing the area of ​​the entire tower that bears wind force during normal times, thus improving the wind resistance of the tower. The windproof cover control module can also have a manual operation mode to manually control the extension and retraction of the telescopic windproof structure 700.

[0031] In one embodiment, such as Figures 2-5As shown, the telescopic windbreak structure 700 includes an extendable folding plate unit 710 and a scissor-type adjustment unit 720. The extendable folding plate unit 710 is composed of multiple arranged folding plate components 711. The sides of two adjacent folding plate components 711 are rotatably connected by a connecting shaft 712. The top of the scissor-type adjustment unit 720 is connected to the ring frame 500, and the intersection points on the scissor-type adjustment unit 720 are connected to the corresponding connecting shafts 712. The bottom of the scissor-type adjustment unit 720 is provided with a post 730. The ring frame 500 is provided with a slot portion 510, and the slot portion 510 corresponds to the post 730 located above. When the extendable folding plate unit 710 is fully extended, the post 730 is inserted into the corresponding slot portion 510. In this embodiment of the invention... Under the control of the wind shield control module, the scissor-type adjustment unit 720 extends or retracts. Its intersection point moves vertically, and the movement of the intersection point drives the corresponding connecting shaft 712 to move vertically. As a result, multiple folding plate components 711 gradually switch between a folded arrangement state and a flat arrangement state to achieve extension and retraction. The multiple flat folding plate components 711 form a windbreak on the side of the climbing platform 200, and the insert 730 is inserted into the slot 510. The scissor-type adjustment unit 720 and the insert 730 can increase the wind resistance of the extended folding plate unit 710 to prevent the wind from impacting the body of the workers. The multiple folding plate components 711 in the folded arrangement state are located on the lower side of the corresponding ring frame 500, which can reduce the intensity of the wind force on the entire iron tower.

[0032] In one embodiment, such as Figures 2-6 As shown, the scissor lift adjustment unit 720 includes an extension / retraction cylinder 724 and multiple scissor lift assemblies 721. Adjacent scissor lift assemblies 721 are connected by two movable joints. A cross pin 722 is provided at the intersection of the scissor lift assemblies 721. A sleeve portion 725 is fixedly connected to the cross pin 722, and the sleeve portion 725 is rotatably connected to the corresponding connecting shaft 712. The extension / retraction cylinder 724 is fixed on the ring frame 500, and its extension / retraction end is connected to the cross pin 722 in the uppermost scissor lift assembly 721. A [missing information - likely a design feature] is provided at the top of the uppermost scissor lift assembly 721. The device has two upper connecting seats 723 that are slidably connected to the ring frame 500. In this embodiment of the invention, the telescopic cylinder 724 drives the uppermost cross pin 722 to move vertically through telescopic movement. Since the two upper connecting seats 723 are slidably engaged with the ring frame 500, under its constraint, the two rods of the scissor bar assembly 721 rotate around the cross pin 722. Multiple scissor bar assemblies 721 rotate synchronously and crosswise, thereby causing multiple cross pins 722 to move vertically and drive the connecting shaft 712 to move vertically through the sleeve part 725, so as to realize the switching of the arrangement state of the folding plate parts 711.

[0033] In one embodiment, such as Figure 1As shown, the outer side of the tower body 100 is also provided with a plurality of circumferentially distributed external support rods 300. The side walls of the external support rods 300 are all fixedly connected to the outer walls of each ring frame 500 through diagonal web members 310. The top of the external support rods 300 is connected to the top of the tower body 100, and the bottom of the external support rods 300 is provided with a tower foot 320 and fixed to the ground through anchor bolts. In this embodiment of the invention, the arrangement of multiple external support rods 300 can effectively disperse the impact force on the tower body 100. The diagonal web members 310 are used to connect multiple ring frames 500 together to form a stable spatial truss system, which efficiently transmits horizontal and vertical loads and improves the stability of the entire tower.

[0034] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the climbing platform 200 has a check groove 210 along its height direction on its surface, and anti-fall teeth are evenly distributed on both sides of the check groove 210. The following rope connection structure 800 includes a hollow follower seat 810, a hook connector, and two side inclined blocks 820. The hollow follower seat 810 is slidably disposed inside the check groove 210, and its two side walls are open. The two side inclined blocks 820 are installed inside the hollow follower seat 810 and can move along the width direction of the check groove 210 at the opening. A switching wedge 860 is disposed between the two side inclined blocks 820. 860 can move along the depth direction of the check groove 210 inside the hollow follower seat 810. The two side inclined blocks 820 are also connected by a compression spring 880. The contact between the side wall of the switching wedge 860 and the side of the side inclined block 820 facing the interior of the hollow follower seat 810 is an inclined surface contact. One end of the switching wedge 860 extends to the outer surface of the hollow follower seat 810. The hook connector is rotatably disposed on the outer surface of the hollow follower seat 810 and is used to connect with the hook of the seat belt. The hook connector is connected to the end of the switching wedge 860 that extends to the outer surface of the hollow follower seat 810. When hooked... When the hook acts on the hook connector, the hook connector rotates, driving the switching wedge 860 to move towards the hollow follower seat 810. In this embodiment of the invention, when the worker climbs up the climbing platform 200, the worker pulls the hook connector with the safety belt so that the entire follower rope connection structure 800 moves upward along the anti-return groove 210. The hook connector will not rotate, and the two side blocks 820 retract into the hollow follower seat 810 under the elastic force of the compression spring 880. Thus, the anti-fall teeth will not block the compression spring 880, ensuring that the follower rope connection structure 800... 0. Unobstructed upward movement of the worker; if the worker falls, the safety rope on their body pulls down on the hook connector, causing the hook connector to rotate and act on the end of the switching wedge 860. The switching wedge 860 acts on the opposite surfaces of the two side inclined blocks 820 through the inclined surface. The side inclined blocks 820 move towards the side wall of the check groove 210. The side of the side inclined block 820 contacts and engages with the anti-fall tooth. The anti-fall tooth prevents the side inclined block 820 from continuing to move downward, thus effectively preventing the entire following rope connection structure 800 from moving downward quickly. The safety rope can be used to suspend the worker, improving safety.

[0035] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the end of the switching wedge 860 extending to the surface of the hollow follower seat 810 is provided with a stop plate 870. The hook connector includes a hook shaft 830, a hook rod 840, and a cam part 850. The two ends of the hook shaft 830 are rotatably mounted on the end face of the hollow follower seat 810 through bearing seats. The cam part 850 is fixed on the hook shaft 830, and its side wall contacts the stop plate 870. The hook rod 840 is fixedly connected to the hook shaft 830 and is used to fasten with the hook of the safety rope. In this embodiment of the invention, in the initial state, the two side inclined blocks 820 are retracted into the hollow follower seat 810 under the elastic force of the compression spring 880. The side inclined blocks 820 are connected by the inclined surface. The switching wedge 860 is used to ensure that the end plate 870 is always in contact with the outer wall of the cam portion 850. When a worker falls, the safety rope is pulled quickly by the worker's weight, causing the hook body rod 840 to rotate. The hook body rod 840 drives the hook shaft 830 to rotate, and the cam portion 850 rotates with the hook shaft 830. Its outer wall acts on the end plate 870, causing the switching wedge 860 to move into the hollow follower seat 810. The switching wedge 860 acts on the opposite surfaces of the two side inclined blocks 820 through the inclined surface. The side inclined blocks 820 move toward the side wall of the check groove 210. The side of the side inclined block 820 contacts and engages with the anti-fall tooth, which prevents the side inclined block 820 from moving further downward.

[0036] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, the climbing ladder structure 400 includes a U-shaped fixed rod 410, a movable sleeve 420, and a blocking block 450. The two ends of the U-shaped fixed rod 410 are fixedly connected to the end face of the climbing platform 200. The movable sleeve 420 is rotatably sleeved in the middle of the U-shaped fixed rod 410. A rear extension frame 430 and a front extension frame 440 are fixed to the outer wall of the movable sleeve 420. The rear extension frame 430 and the front extension frame 440 are on the same plane. The blocking block 450 is fixed to the end face of the climbing platform 200. The front extension frame 440 is in a horizontal state and faces the climbing platform 200. At 00:00, the end of the front mounting frame 440 furthest from the blocking block 450 abuts against the lower surface of the blocking block 450. In this embodiment of the invention, the U-shaped fixing rod 410 serves to support climbing, the rear mounting frame 430 is easy for the operator to grip, the front mounting frame 440 and the rear mounting frame 430 increase the support surface for the operator's feet, which can prevent the feet from slipping. The blocking block 450 can prevent the front mounting frame 440 from flipping upwards, and can prevent the operator's feet from becoming unstable due to the rotation of the front mounting frame 440 and the rear mounting frame 430 after stepping on the rear mounting frame 430.

[0037] The above embodiment provides a communication tower, the working principle of which is as follows:

[0038] When workers need to work at heights on the tower, they first connect their safety harness to the following rope connection structure 800 on the climbing platform 200. This structure is slidably installed in the anti-return groove 210 of the climbing platform 200, so that the connection point of the safety rope can move up and down with the workers, providing continuous protection throughout the climbing process.

[0039] During the climbing or operation, wind sensors 600 distributed on the ring platform 500 at various heights continuously monitor real-time outdoor wind data and their location information at different heights. This data is transmitted in real time to the windproof cover control module in the machine room. The control module has a pre-stored wind-height model. Based on the received wind data and height information, it comprehensively analyzes and judges whether the wind force at the current location and at each height has reached a level that poses a safety threat to the workers, such as strong winds that may cause instability or falls.

[0040] When a safety threat is detected: the windproof shield control module issues an extension command to the retractable windbreak structure 700 at the corresponding height or in the threat area; specifically, the control module drives the retraction cylinder 724 to actuate, causing the scissor lift assembly 721 to unfold, resulting in the vertical movement of multiple cross pins 722. The cross pins 722, through the sleeve portion 725, drive the connecting shaft 712 between multiple folding plate components 711 in the extension folding plate unit 710 to move, thereby gradually unfolding the folded folding plate components 711, forming vertical windbreaks on both sides of the climbing platform 200. Simultaneously, the bottom 730 of the scissor lift adjustment unit 720 is inserted into the slot portion 510 of the ring frame 500 for fixation, enhancing the structure's wind resistance. The unfolded windbreak structures on both sides together form a "windproof channel" surrounding the climbing path, effectively reducing the direct impact of strong winds on workers, preventing them from being blown off the ladder, reducing fear and physical exertion, and ensuring safety.

[0041] When the wind force is determined to be low or pose no safety threat, the windbreak control module issues a retraction command. The retraction cylinder 724 reverses its movement, causing the scissor lift assembly 721 to retract, which in turn causes the folding plate 711 to fold back and attach to the underside of the ring frame 500. In this state, the wind-exposed area of ​​the tower is greatly reduced, which is beneficial to the overall wind resistance of the structure. At the same time, it provides workers with a wide field of vision, making it easier to observe the surrounding environment and equipment, and also avoids the stuffy feeling that may occur in a confined space.

[0042] The windproof cover control module can also be switched to manual operation mode, allowing managers to remotely or locally control the extension and retraction of specific sections of the windproof cover according to the actual situation.

[0043] During the climb, the follow-up rope structure 800 provides simultaneous fall protection.

[0044] During normal upward climbing: The operator pulls the hook rod 840 upward using the safety belt, causing the entire hollow follower seat 810 to slide smoothly upward within the check groove 210. At this time, the retraction spring 880 causes the two side inclined blocks 820 to retract, preventing interference with the anti-fall teeth on the side wall of the check groove.

[0045] In the event of an accidental fall: The impact of the worker's fall instantly pulls down the hook rod 840 via the safety rope, causing it to rotate the hook shaft 830 and the cam part 850. The cam part 850 presses against the abutment plate 870, pushing the switching wedge block 860 into the hollow follower seat 810; the inclined surface of the switching wedge block 860 forces the two side inclined blocks 820 to extend to both sides, locking them firmly into the anti-fall teeth on the side wall of the check groove 210. This mechanical self-locking mechanism can immediately lock, preventing the follower rope connection structure 800 and the connected safety belt from continuing to slide down, thereby suspending the falling personnel and achieving fall protection.
