[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] A communication tower is a tall steel or composite material structure used to support communication antennas, microwave transmission equipment, wireless base stations, etc. Its main function is to transmit, receive, and relay wireless signals, and it is widely used in mobile communications (such as 4G / 5G), broadcasting, satellite communications, emergency communications, and other fields. Its core role is to expand signal coverage through its height and location advantages, ensuring the stability and continuity of the communication network.

[0038] Existing communication towers suffer from complex installation, low deployment efficiency, and long construction cycles. Traditional towers rely on on-site welding or bolt assembly, requiring significant manpower and time (typically 2-4 weeks), making it difficult to meet the demands of rapid and dense 5G network deployment. High transportation costs: Steel structure towers are large and heavy, making transportation difficult in remote mountainous areas or areas with poor transportation. Reliance on heavy machinery: High demand for hoisting equipment leads to increased costs and may damage the surrounding environment. Impacts: Delays network coverage speed, increases initial investment costs for operators, and lacks environmental adaptability. Problems include: Geographical limitations: Traditional designs are insufficiently adaptable to earthquake zones, strong wind areas (such as typhoon-prone areas), and highly corrosive environments (such as coastal salt spray and industrial pollution areas), easily leading to structural deformation or corrosion. Poor scene adaptability: In urban areas, towers are large and have an obtrusive appearance, making it difficult to integrate with the architectural landscape; in rural areas, tower designs are redundant, resulting in resource waste. Impacts: Shortened tower lifespan (less than 10 years in some severely corroded areas), limiting the flexibility and aesthetics of network coverage.

[0039] Reference Figures 1-6As shown, a quick-installation communication tower includes a base column 100, a base plate 200, an outer tower column 300, an inner tower column 500, and a signal box 800. The base column 100 is fixedly connected to the upper surface of the base plate 200. A lower hemispherical shell 101 is fixedly connected to the top of the base column 100. The lower hemispherical shell 101 is made of Q355B low alloy steel precision casting, with a surface treated by sandblasting and hot-dip galvanizing, and a thickness of 25mm. The shell joint surface is equipped with a 3mm thick EPDM sealing strip, achieving a waterproof rating of IP67. The outer tower column 300 is located directly above the base column 100. The bottom of the outer tower column 300 is fixedly connected to an upper hemispherical shell 301. The upper hemispherical shell 301 is fixedly connected to the lower hemispherical shell 101 by a first fastening bolt 302. The first fastening bolt 302 is an M30×220mm double-ended stud. The pre-tightening force is controlled by the torque-angle method, and the final tightening torque value is set to 1250 N·m. Eight sets of Φ40mm locating pins are set at the shell connection to ensure that the installation positioning accuracy is ≤0.5mm. The bolt connection between the lower hemispherical shell 101 and the upper hemispherical shell 301 enables the rapid docking of the outer tower column 300 and the base column 100. The modular design significantly shortens on-site installation time. The inner tower column 500 is slidably inserted into the interior of the outer tower column 300. The signal box 800 is fixedly connected to the top of the inner tower column 500. Three foot blocks 400 are fixedly connected to the upper surface of the base plate 200. The foot blocks 400 are arranged in a circle around the upper surface of the base plate 200, forming a triangular support system. Combined with the structure of the second bottom insert column 401 penetrating the base plate 200, this effectively distributes the tower load to the foundation and enhances the anti-overturning ability. One end of the foot block 400 has a first groove 4. 02. A second groove 404 is provided at the other end of the foot block 400. A sleeve post 405 is fixedly connected to the inner wall of the second groove 404. A second bottom insertion post 401 is fixedly connected to the bottom end of the foot block 400. The second bottom insertion post 401 penetrates the surface of the base plate 200. The combination of the sleeve post 405 and the second groove 404 provides a pre-installed interface for the subsequent steel cable 700 system, which improves the integration of the cable system by 40%. At the same time, the second bottom insertion post 401 will extend into the ground through the surface of the base plate 200, which greatly improves the effectiveness of the lightning protection and grounding system.

[0040] In a further preferred embodiment, a first reinforcing rib 102 is fixedly connected to the side of the base column 100, and the bottom end of the first reinforcing rib 102 is fixedly connected to the upper surface of the base plate 200. The first reinforcing rib 102 forms a spatial triangular stable structure, which increases the bending strength of the connection between the base column 100 and the base plate 200 by 35%, and can effectively suppress structural deformation caused by foundation settlement.

[0041] In a further preferred embodiment, the inner top wall of the upper hemisphere 301 is fixedly connected to a first bottom insert 306, which sequentially penetrates the lower hemisphere 101, the base column 100, and the base plate 200. The design of the first bottom insert 306 penetrating the lower hemisphere 101, the base column 100, and the base plate 200 forms a vertically continuous force transmission path, thereby increasing the shear bearing capacity of the connection node between the upper and lower hemispheres by 2.3 times.

[0042] In a further preferred embodiment, a second reinforcing rib 303 is fixedly connected to the top of the first bottom insert 306. The edge of the second reinforcing rib 303 is fixedly connected to the inner wall of the upper hemisphere 301. A first traction post 304 is fixedly connected to the bottom of the second reinforcing rib 303. The second traction post 403 is rotatably connected inside the first groove 402. The first traction post 304 penetrates the lower hemisphere 101 and is fixedly connected to the second traction post 403 through a connector 305. The first traction post 304 and the second traction post 403 form a spatial truss system through the connector 305, which converts the tensile force borne by the foot block 400 into the pressure at the connection of the spherical shell, increasing the tensile strength of the node by 80%. The radial arrangement of the second reinforcing rib 303 makes the stress distribution of the upper hemisphere 301 more uniform.

[0043] Preferably, there are three second reinforcing ribs 303, and the positions of the second reinforcing ribs 303 correspond to those of the foot block 400. The three second reinforcing ribs 303 and the foot block 400 form a corresponding force transmission path, realizing the proportional distribution of load and eliminating the stress concentration phenomenon common in traditional towers.

[0044] In a further preferred embodiment, the outer tower column 300 has a threaded column 900 inside, and the inner tower column 500 is threadedly sleeved on the surface of the threaded column 900. The inner tower column 500 has a hexagonal columnar design. The threaded transmission mechanism of the threaded column 900 and the inner tower column 500, in conjunction with the hexagonal columnar design, achieves millimeter-level precision lifting and lowering adjustment. The hexagonal cross-section increases the torsional stiffness of the inner tower column 500 by 6 times.

[0045] In a further preferred embodiment, a driven bevel gear 901 is fixedly connected to the bottom end of the threaded column 900. The driven bevel gear 901 is rotatably connected to the inner bottom of the outer tower column 300. A motor 902 is fixedly connected to the surface of the outer tower column 300. A driving bevel gear 903 is fixedly connected to the output end of the motor 902. The driving bevel gear 903 meshes with the driven bevel gear 901. The meshing transmission system of the driven bevel gear 901 and the driving bevel gear 903 converts the horizontal torque of the motor 902 into a vertical driving force. The double bearing support structure ensures that the radial runout of the threaded column 900 is <0.05mm.

[0046] In a further preferred embodiment, a fixing collar 600 is fixedly sleeved on the top surface of the outer tower column 300, and a second fastening bolt 601 is threaded into the surface of the fixing collar 600. A locking hole 501 is opened on the bottom side of the inner tower column 500, and the end of the second fastening bolt 601 is inserted into the inside of the locking hole 501. The fixing collar 600 forms a three-point positioning mechanism through the cooperation of the second fastening bolt 601 and the locking hole 501, so that the axial fixed bearing capacity of the inner tower column 500 reaches 12 tons.

[0047] In a further preferred embodiment, three fixing blocks 602 are fixedly connected to the side of the fixing collar 600, and steel cables 700 are fixedly connected to the top of the fixing blocks 602. The other end of the steel cables 700 passes around the sleeve post 405 and is tightened by the locking block 701. The steel cables 700 connected to the fixing blocks 602 pass around the sleeve post 405 and are tightened by the locking block 701, forming a spatial suspension grid, which increases the overall lateral stiffness of the tower by 60%.

[0048] In a further preferred embodiment, a connecting frame 502 is rotatably connected to the top side of the inner tower column 500, and a traction wheel 503 is rotatably connected to the bottom end of the connecting frame 502. The steel cable 700 extends out from the inside of the traction wheel 503. The rotatable connection design between the connecting frame 502 and the traction wheel 503 can automatically compensate for the thermal expansion and contraction deformation of the steel cable 700, and the hinged structure gives the steel cable system three-dimensional self-adaptive capability.
