Description

Technical Field

[0001] The present invention relates to the technical field of communication towers, and in particular to a multi-section spliced communication tower with high stability. Background Art

[0002] A communication tower belongs to a type of signal transmission tower, also known as a signal transmission tower or signal tower. Its main function is to support signal transmission and serve as a support for the signal transmission antenna. It is used by communication departments such as mobile, Unicom, and the Global Positioning System (GPS) of transportation.

[0003] With the rapid development of communication technology, as the core infrastructure for signal coverage, the construction demand for communication towers is increasing day by day. Traditional communication towers mostly adopt a multi-section splicing structure. However, during the high-altitude hoisting and splicing process, the following technical pain points exist: During the hoisting of tower sections, the axis of the two sections is prone to deviation due to factors such as wind force and hoisting equipment errors, and repeated adjustments are required, resulting in low efficiency. Moreover, manual high-altitude correction poses a safety hazard. Existing plug-in tower sections rely on flange bolts for direct fixation. However, before the bolts are tightened, there is a lack of effective temporary support between the tower sections, and it is easy for the interface to be worn or the structure to shift due to shaking.

[0004] In view of the above situation, the present invention proposes a new type of spliced communication tower to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-section spliced communication tower with high stability to solve the problems proposed in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A multi-section spliced communication tower with high stability, comprising: The first communication tower section and the second communication tower section. A connecting member is provided on the first communication tower section, and a centering auxiliary mechanism is provided on the second communication tower section. Through the cooperation of the centering auxiliary mechanism and the connecting member, the stability of the centering and plugging of the first communication tower section and the second communication tower section is improved. The connecting member is arranged at the position where the first communication tower section and the second communication tower section are connected. The centering auxiliary mechanism is arranged inside the second communication tower section. The centering auxiliary mechanism includes a bracket installed inside the second communication tower section. A winch assembly is installed on the bracket. The winch assembly is installed on the bracket and can perform a winding action. The cooperation of the centering auxiliary mechanism and the connecting member is used to assist the centering action of the second communication tower section with the first communication tower section during the suspension process.

[0007] Furthermore, the connecting member includes at least two hanging rings. The two hanging rings are symmetrically arranged, and each hanging ring is hung with a double-headed lifting rope. Both ends of the double-headed lifting rope are hooks, and they are connected to the hanging rings through the hooks.

[0008] Further, a towing rope is fixed on the winding roller of the winch. The end of the towing rope is connected with a double-headed lifting rope II through a hook, and the hook of the double-headed lifting rope II is connected with the hook of the double-headed lifting rope I.

[0009] Further, the bracket is a cross-shaped frame formed by welding two groups of square steel pipes up and down. The winch assembly further includes a supporting plate, on which the main body of the winch is installed. Both sides of the bottom of the supporting plate are fixed with side plates, and a right angle is formed between the side plates and the bottom wall of the supporting plate. On the opposite sides of the two parallel square steel pipes located above, a resisting plate is fixed respectively. On one side of each side plate, a row of pulleys that can roll on the resisting plate is rotatably installed. Threaded holes are opened at the top of the square steel pipe and on both sides of the supporting plate for installing fixing bolts to fix the winch assembly.

[0010] Further, a window is opened on the communication tower section II. The length and width of the window are such that the winch assembly can be placed inside the communication tower section II through the window. The height of the bottom wall of the window is not higher than the top surface height of the square steel pipe in contact with the winch assembly, which is convenient for the installation of the winch assembly.

[0011] Further, a hoop is fixed on one of the square steel pipes. There is a hole on the hoop and the axis of the hole is consistent with the axis of the communication tower section. The towing rope passes through the hoop, and the hook at the end of the towing rope is fixed at the joint at the end of the towing rope by screwing.

[0012] Further, a stabilizing member is provided at the communication tower section II. The stabilizing member includes two positioning fork arms, which are rotatably connected in the middle and there is a hole at the connection for the towing rope to pass through.

[0013] Further, two symmetrically arranged threaded holes are also opened at the communication tower section II. Screw arms are screwed at the threaded holes. At the inside of the communication tower section II, hinge blocks are rotatably installed on both screw arms. One end of each of the two positioning fork arms is hinged to the hinge block.

[0014] Further, a protruding surrounding edge is fixed on the inner wall at one end of the communication tower section I close to the communication tower section II. The side facing the communication tower section II of the protruding surrounding edge is beveled, and the other side is flat. Planes are provided at the ends of the positioning fork arms away from the hinge blocks to fit the flat surface of the protruding surrounding edge. Before the communication tower section I and the communication tower section II are butted, the gap width between the two positioning fork arms is smaller than the diameter of the protruding surrounding edge.

[0015] Further, a flange is provided at the connection between the communication tower section I and the communication tower section II. The communication tower section I and the communication tower section II are fixedly connected through the flange.

[0016] Compared with the prior art, the beneficial effects of the present invention are: Through the setting of the centering auxiliary mechanism and others, this highly stable multi-section spliced communication tower reduces the manual high-altitude correction work. With the cooperation of the centering auxiliary mechanism and the connecting piece, it can effectively avoid the problem of manual high-altitude correction required due to axis deviation during the hoisting of tower sections, reducing the high-altitude operation risk of construction personnel, ensuring personal safety, and shortening the installation time at the same time. Through the auxiliary centering function, it can quickly adjust the position of the tower section, make the two tower sections quickly coaxial, avoid the traditional problem of repeatedly adjusting the axis deviation, significantly improve the splicing efficiency of the tower section, and shorten the installation cycle of the communication tower.

[0017] At the same time, in terms of structural stability, first, it provides temporary support guarantee. Before the flange bolts are tightened, the stabilizing piece can provide effective temporary support between tower sections, prevent interface wear or structural deviation caused by shaking, ensure the accuracy and stability of the tower section docking, and enhance the reliability of the overall structure of the communication tower. Second, it improves the wind resistance and seismic resistance. This tower adopts a columnar structure and has good wind resistance itself. Combined with the tight and stable connection method between tower sections and the temporary support, it can maintain stability in natural disasters such as bad weather and earthquakes, reducing the risk of shaking and damage.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Key precautions Lifting safety: The whole process adopts multi-hoisting point control to avoid the swing of the tower section.

[0022] Hoist power: Select a motor with a moderate power to avoid structural damage caused by excessive traction force.

[0023] Stabilizer adjustment: The positioning fork arm 7 needs to be unfolded after insertion to ensure temporary stability.

[0024] Manual operation: Safety measures for high-altitude operations shall be equipped for the tightening of flange bolts and the operation of stabilizers.

[0025] As Figure 1 and Figure 3 shown, the present invention provides a technical solution: a multi-section spliced communication tower with high stability, including a first communication tower section 1 and a second communication tower section 2. A connecting member is provided on the first communication tower section 1, and a centering auxiliary mechanism is provided on the second communication tower section 2. Through the cooperation of the centering auxiliary mechanism and the connecting member, the hoisting stability of the first communication tower section 1 and the second communication tower section 2 is improved; The first communication tower section 1 and the second communication tower section 2 are coaxially inserted and fixed. It should be noted that the first communication tower section 1 and the second communication tower section 2 do not specifically refer to a certain tower section on the communication tower. On a specific communication tower, every two adjacent segments can be called the first communication tower section 1 and the second communication tower section 2, where the segment located lower is defined as the first communication tower section 1.

[0026] As Figure 2 、 Figure 3 and Figure 4As shown, to ensure the smooth implementation of this embodiment, regarding this specific embodiment, it should be understood that the connecting member is disposed at the connection position between the first communication tower section 1 and the second communication tower section 2. Specifically, the connecting member includes at least two hanging rings 3. The two hanging rings 3 are symmetrically arranged and each hanging ring 3 is hung with a double-headed lifting rope 4. Both ends of the double-headed lifting rope are hooks, and the hooks are connected to the hanging ring 3. It should be understood that the centering auxiliary mechanism is disposed inside the second communication tower section 2. The centering auxiliary mechanism includes a bracket 501 installed inside the second communication tower section 2. A winch assembly 5 is installed on the bracket 501 and can perform a winding action. A traction rope 509 is fixed on the winding roller of the winch. The end of the traction rope 509 is connected to a double-headed lifting rope 6 through a hook. The hook of the double-headed lifting rope 6 is connected to the hook of the double-headed lifting rope 4. In the above embodiment, all the hooks are lockable hooks to ensure the stability after connection.

[0027] As Figure 3 and Figure 4As shown, in the specific operation process, the communication tower section 1 is the basic section. It is necessary to determine that after the communication tower section 1 is installed as the basic section, the communication tower section 2 can be installed. That is to say, the communication tower section 1 should be installed at least after being installed on the ground or on a certain section before the installation of the communication tower section 2 can be carried out. Before the installation of the communication tower section 2, the winch assembly 5 needs to be installed on the bracket 501 of the communication tower section 2. The position of the winch assembly 5 can be adjusted through cooperation with the bracket 501. During the adjustment process, it is necessary to ensure that the position where the towing rope 509 naturally hangs is coaxial with the communication tower section 2 as much as possible, and it is necessary to ensure that the length of the towing rope 509 is long enough, at least twice the length of the communication tower section, leaving enough length redundancy. The towing rope 509 is connected to the double-headed lifting rope 1 through the double-headed lifting rope 2. The double-headed lifting rope 1 is symmetrically arranged. After connecting the double-headed lifting rope 2, the connection point of the double-headed lifting rope 1 and the double-headed lifting rope 2 can be basically located at the axis of the communication tower section. During hoisting, it is necessary to ensure the stability of hoisting, adopt multiple hoisting points for suspension, and keep the communication tower section as vertical as possible during hoisting. After hoisting above the communication tower section 1, it should be coaxial with the communication tower section 1 as much as possible. Subsequently, the winch assembly 5 is started. The winch assembly 5 gradually winds up the towing rope 509 during the winding process. However, it should be noted that the cooperation between the centering auxiliary mechanism and the connecting piece is used to assist the centering of the communication tower section 1 and the communication tower section 2, and is not used for the active approach and installation of the communication tower section 1 and the communication tower section 2. The alignment of the communication tower section 2 with the communication tower section 1 still depends on the movement of the hoisting of the communication tower section 2. Therefore, there are requirements for the motor power of the winch assembly 5. It cannot be too large to break the towing rope 509 and cause internal damage to the communication tower section, and at the same time, the power cannot be too small to lose the ability of auxiliary centering. Here, the requirements for the motor power of the winch assembly 5 are not precise, so no specific restrictions are made here. During the centering process of the winch assembly 5, the position or posture of the hoisting adjustment can be determined, etc., to reduce the difficulty of hoisting centering.

[0028] As Figure 4 shown, to ensure the smooth implementation of the above embodiments, it should be understood that the bracket 501 is a cross-shaped frame formed by welding two sets of square steel pipes up and down, leaving enough space for installing the winch assembly 5 and the vertical suspension of the towing rope 509 while ensuring strength.

[0029] The hoist assembly 5 further includes a supporting plate 502, on which the hoist main body 503 is installed. It should be noted that this hoist is powered by a battery, that is, a battery is provided on the supporting plate 502 to supply power to the motor of the hoist, which means that the hoist assembly 5 does not rely on an external power source during operation, avoiding the problem that it is difficult to traction electricity when it is too high off the ground. On both sides of the bottom of the supporting plate 502, side plates 505 are fixed. A right angle is formed between the side plates 505 and the bottom wall of the supporting plate 502, and it just inserts along two parallel square steel pipes. On the opposite sides of these two parallel square steel pipes, a resisting plate 504 is fixed. On one side of each side plate 505, a row of pulleys 506 that can roll on the resisting plate 504 are rotatably installed. Threaded holes are opened at the top of these two square steel pipes and on both sides of the supporting plate 502 for installing fixing bolts 507 to fix the hoist assembly 5.

[0030] As Figure 5 and Figure 6 shown, regarding the above embodiment, it should be noted that a window 11 is opened on the communication tower section two 2. The length and width of the window 11 should at least be able to allow the hoist assembly 5 to be placed inside the communication tower section two 2 from the window 11, and the bottom wall position of the window 11 should not be higher than the top surface height of the square steel pipe in contact with the hoist assembly 5 to facilitate the installation of the hoist assembly 5. After installing the hoist assembly 5 on the bracket 501, the installation of the hoist assembly 5 is completed. It should also be noted that a hoop 510 is fixed on one of the square steel pipes. There are holes on the hoop 510 and the axis of the holes is consistent with the axis of the communication tower section. The towing rope 509 passes through the hoop 510, which can play a certain limiting effect on the towing rope 509. It should also be noted that the hook at the end of the towing rope 509 is fixed to the joint at the end of the towing rope 509 by screwing, and the hook is detachable for convenient removal. In addition, a lifting ring 508 is provided on the supporting plate 502. After removing the hoist assembly 5 from the communication tower section two 2, the hoist assembly 5 can be suspended and removed.

[0031] Looking back Figure 1 Regarding this solution, it should also be noted that the fixation between the communication tower section one 1 and the communication tower section two 2 depends on the screwed fixation of the flange. During the actual installation process, the flange fixation between the communication tower section one 1 and the communication tower section two 2 requires manual climbing to the flange for installation. And in this embodiment, the hoist assembly 5 also needs to be disassembled and assembled. Therefore, after the communication tower section one 1 is inserted into the communication tower section two 2, it is necessary to maintain the stability between the communication tower section one 1 and the communication tower section two 2. And the connection between the communication tower section one 1 and the communication tower section two 2 is an insertion connection, which has a high requirement for the wall end of the tower section. Therefore, a stabilizing member is provided at the communication tower section two 2 to improve the stability of the connection between the communication tower section one 1 and the communication tower section two 2 for a period of time after docking.

[0032] As Figure 3As shown in the figure, to ensure the smooth implementation of the above embodiments, it should be understood that the stabilizing member includes two positioning fork arms 7. The middle parts of the two positioning fork arms 7 are rotatably connected and there is a hole at the connection for the traction rope 509 to pass through. Two symmetrically arranged threaded holes are also provided at the communication tower section two 2, and a threaded connection arm 9 is screwed at the threaded holes. By rotating the threaded connection arm 9, the threaded connection arm 9 can be pushed into the interior of the communication tower section two 2. At the interior of the communication tower section two 2 where the two threaded connection arms 9 are located, hinge blocks 8 are rotatably installed. One end of each of the two positioning fork arms 7 is hinged to the hinge block 8. By synchronously rotating the two threaded connection arms 9, the opening and closing degree of the ends of the positioning fork arms 7 can be adjusted.

[0033] As Figure 3 shown, it should also be understood that regarding the above embodiments, a protruding edge 101 is fixed to the inner wall of one end of the communication tower section one 1 close to the communication tower section two 2. One side of the protruding edge 101 facing the communication tower section two 2 is beveled, and the other side is flat. Planes are provided at the ends of the positioning fork arms 7 away from the hinge blocks 8 to fit the flat surfaces of the protruding edge 101. Before the communication tower section one 1 and the communication tower section two 2 are docked, it is necessary to ensure that the gap width between the two positioning fork arms 7 is smaller than the diameter of the protruding edge 101. After the communication tower section one 1 and the communication tower section two 2 are docked, by rotating the threaded connection arms 9, the positioning fork arms 7 are opened until the ends are stuck to the flat surfaces of the protruding edge 101, forming an X-shaped frame between the communication tower section one 1 and the communication tower section two 2, improving the connection stability between the communication tower section one 1 and the communication tower section two 2.

[0034] In summary, the above device realizes the installation of the communication tower according to the following steps: Step 1: Installation of the basic section Fix the communication tower section one 1 as the basic section on the ground or the top of the already installed tower section, ensure that its verticality meets the requirements, symmetrically install at least two hanging rings 3 at the top of the communication tower section one 1, and hang the double-headed lifting rope one 4, and the hook needs to be locked.

[0035] Step 2: Installation of the winch assembly 5 Send the winch main body 503 and the supporting plate 502 into the tower through the window 11 on the side of the communication tower section two 2. Insert the side plate 505 at the bottom of the supporting plate 502 into the square steel pipe of the bracket 501. Adjust the position of the winch so that the traction rope 509 naturally hangs vertically and aligns with the tower axis. Use the fixing bolt 507 to lock the supporting plate 502 and the square steel pipe. Check the battery power supply system and check the running state of the winch. The end of the traction rope 509 passes through the hoop 510 for limiting, and is connected to the double-headed lifting rope two 6 through a detachable hook, ensuring that the hook is locked.

[0036] Step 3: Hoisting and centering of the communication tower section two 2 Suspend the second communication tower section 2 using multiple suspension points, slowly lift it to directly above the first communication tower section 1 while maintaining a vertical posture, initially adjust the position to make the two tower sections approximately coaxial. A slight deviation is allowed. Connect the hook of the double-headed lifting rope two 6 to the hook of the double-headed lifting rope one 4 of the first communication tower section 1, and it needs to be locked. Start the winch assembly 5, slowly wind up the towing rope 509, adjust the position of the second communication tower section 2 through symmetric pulling force, gradually eliminate the horizontal deviation, observe the alignment of the axes of the two tower sections, and make fine adjustments through the cooperation of the lifting equipment and the winch until they are completely coaxial.

[0037] Step Four: Insertion Fixing and Installation of Stabilizing Parts Slowly lower the second communication tower section 2 so that its lower end inserts into the inner wall of the first communication tower section 1 to complete the insertion action. After ensuring that the flange plates 10 of the two tower sections are in contact, pause the lifting equipment to maintain a temporary stable state. Climb into the second communication tower section 2, synchronously rotate the two screw connection arms 9, push the articulated block 8 to move towards the tower interior, drive the positioning fork arms 7 to open, and make the end plane closely adhere to the plane of the protruding border 101 on the inner wall of the first communication tower section 1. Check whether the X-shaped support structure formed by the positioning fork arms 7 is completely clamped to ensure there is no looseness.

[0038] Step Five: Tightening of Flange Bolts Manually climb to the connection of the two tower sections, tightly connect the first communication tower section 1 and the second communication tower section 2 with bolts, check that the torque of all bolts meets the design requirements to ensure the connection rigidity.

[0039] Step Six: Removal of the Winch and Completion of Follow-up Work Remove the winch assembly 5, disconnect the towing rope 509 from the double-headed lifting rope two 6, recover the towing rope 509 to the winch, remove the fixing bolts 507, slide the winch assembly 5 out along the square steel pipe, move the second communication tower section 2 out through the window 11, close the window 11, and restore the integrity of the tower structure.

[0040] Step Seven: Circular Installation of Subsequent Tower Sections Repeat the process, regard the currently installed second communication tower section 2 as the new "first communication tower section 1", and install subsequent tower sections section by section upwards according to the above steps.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
