Description

Technical Field

[0001] This utility model belongs to the field of communication tower technology, specifically relating to a multifunctional tower with a double-layer hollow structure. Background Technology

[0002] A single-tube tower is a common type of communication tower, comprising a tower body and a working platform connected to the upper part of the tower body. A lower opening is formed in the bottom wall of the tower body, and an upper opening is formed in the wall where the working platform is located. The antenna support is fixed to the railing of the working platform. The tower body is characterized by a ladder connected to it, consisting of a main ladder rod and crossbars connected to the main ladder rod. The main ladder rod is fixedly connected to a support frame, and the support frame is screwed into a connecting bracket located on the inner wall of the tower body.

[0003] It has a simple and beautiful structure, occupies a small area, and can be installed quickly. However, it also has some disadvantages, such as difficulty in quality control due to the large number of welds, and relatively poor wind resistance due to the large displacement of the pole in strong winds. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multifunctional iron tower with a double-layer hollow structure.

[0005] The technical solution adopted to solve the above technical problems is as follows: a multi-functional iron tower with a double-layer hollow structure, including a base, a first cylinder installed on the top of the base, a second cylinder installed on the top of the first cylinder, a central column installed at the middle position of the top of the base, an installation groove opened inside the central column, an electric cylinder installed at the top of the installation groove, an electrical control device installed at the bottom of the installation groove, a support plate installed at the output end of the electric cylinder, a motor installed at the top side of the support plate, a first bevel gear installed at the output end of the motor, two support rods hinged to the bottom of the support plate, a connecting rod hinged to the end of the two support rods away from the hinge point, a second bevel gear installed at one end of the connecting rod, a connecting rod installed on the side of the second bevel gear, ventilation holes opened on the sides of both ends of the first cylinder, and limit rings installed at both ends of the first cylinder.

[0006] Furthermore, the end of the support rod that is hinged to the support plate is flat-headed, and the number of ventilation holes is multiple and evenly distributed on the first cylinder. Based on the above, and combined with the shape of the support plate used, the flat-headed design makes it easier to connect the support rod and the support plate by hinge, and the opening and distribution of multiple ventilation holes form a hollow structure, thereby improving wind resistance.

[0007] Furthermore, both the first and second cylinders are enclosed around the central column. The outer side of the limiting ring fits against the inner side of the second cylinder. The limiting ring and the interior of the second cylinder are both provided with threaded holes that match the position of the connecting rod. Based on the above, the positional relationship between the cylinders and the central column on the base can be seen. Combined with the components installed on the central column, the central column is hidden inside the cylinders, while the cylinders can be stably connected through the components in the central column.

[0008] Furthermore, the first bevel gear meshes with the second bevel gear. The depth of the tooth groove on the first bevel gear is greater than the descent height of the electric cylinder, and the length of the tooth on the second bevel gear is greater than the depth of the tooth groove on the first bevel gear. Based on the above, and in combination with the support rod and support plate used, the second bevel gear can still maintain meshing with the first bevel gear after moving with the support rod.

[0009] Furthermore, the end of the connecting rod extending outside the middle rod is provided with a threaded head, and the rotation direction of the second bevel gear matches the screwing direction of the threaded head. The threaded head can be combined with the threaded hole mentioned above, and a threaded connection is achieved under the rotation of the second bevel gear.

[0010] Furthermore, the electrical control device is electrically connected to the electric cylinder and the motor, and the electric control device controls the electric cylinder and the motor to perform actions.

[0011] The beneficial effects of this utility model are as follows: This utility model adopts a double-layer structure formed by a central column and an outer cylinder, with hollowed-out through holes on the outer cylinder. The central column and the cylinder are connected by components installed inside the central column. The hollowed-out through holes reduce the windward area of ​​the tower, allowing air to pass through and reducing wind resistance. The hollowed-out areas alter the airflow characteristics, reducing the formation of eddies and their impact on the tower, thus reducing wind-induced vibration. By rationally arranging the hollowed-out areas, wind loads can be effectively dispersed, making the wind force more evenly distributed across the entire tower, increasing the tower's wind resistance. The concealed central column enhances overall stability. Compared to existing single-tube towers, it is more wind-resistant and stable, and assembly is simpler than the multi-section welding method of single-tube towers. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0015] like Figures 1 to 3 As shown, this embodiment of a multi-functional iron tower with a double-layer hollow structure includes a base 1, a first cylindrical body 2 installed on the top of the base 1, a second cylindrical body 3 installed on the top of the first cylindrical body 2, and a central column 4 installed in the middle of the top of the base 1. The first cylindrical body 2 and the second cylindrical body 3 are both covered by the central column 4. After assembly, the bottommost cylindrical body and the bottom of the central column 4 are welded to the base 1. The interior of the central column 4 has an installation groove 5. An electric cylinder 6 is installed at the top of the installation groove 5, and an electrical control device 7 is installed at the bottom of the installation groove 5. A support plate 8 is installed at the output end of the electric cylinder 6. A motor 9 is installed on the top side of the support plate 8. A first bevel gear 10 is installed at the output end of the motor 9. Two support rods 11 are hinged to the bottom of the support plate 8. The end of the support rod 11 that is hinged to the support plate 8 is flat. Since the support rod 11 is connected to the support plate 8 in a hinged manner, one end of the support rod 11 is made into a flat shape, which makes it convenient to install the hinged parts. Furthermore, since the connection method is hinged, when the support plate 8 moves downward, the end of the support rod 11 away from the hinge point extends outward due to the movement of the support plate 8 caused by the connecting rod 13 passing through the central column.

[0016] like Figure 3As shown, a connecting rod 16 is hinged to one end of each of the two support rods 11 away from the hinge point. A second bevel gear 12 is mounted on one end of the connecting rod 16. The first bevel gear 10 meshes with the second bevel gear 12. The depth of the tooth groove on the first bevel gear 10 is greater than the lowering height of the electric cylinder 6. The length of the teeth on the second bevel gear 12 is greater than the depth of the tooth groove on the first bevel gear 10. A connecting rod 13 is mounted on the side of the second bevel gear 12. One end of the connecting rod 13 extending outside the middle rod 4 is provided with a threaded head, and the rotation direction of the second bevel gear 12 is the same as that of the threaded head. The screwing direction of the thread head is matched. Through this section and the above content, as the support plate 8 moves down, the bevel gears can mesh with each other. Due to the design of the groove and teeth, when the thread head rotates and screws into the threaded hole, the connecting rod 13 will continue to move forward. Therefore, the size of the groove and teeth is designed to ensure that the meshing between the gears is always maintained as the connecting rod 13 moves into place. Due to the meshing of the gears, the locking of the motor 9, and the engagement between the threads, a stable connection is formed between the cylinder and the central column 4.

[0017] like Figure 1 and Figure 3 As shown, ventilation holes 14 are opened on the sides of both ends of the first cylinder 2. There are multiple ventilation holes 14 evenly distributed on the first cylinder 2. Limiting rings 15 are installed at both ends of the first cylinder 2. The outer side of the limiting rings 15 fits against the inner side of the second cylinder 3. The limiting rings 15 and the interior of the second cylinder 3 are provided with threaded holes that match the position of the connecting rod 13. The positions of the ventilation holes 14 and the limiting rings 15 can be seen from the figure. Combined with the above content, the position of the mounting groove 5 can be determined. In order to ensure that the components can be aligned smoothly during assembly, marking points can be made on the central column 4 and the cylinder. The electrical control device 7 is electrically connected to the electric cylinder 6 and the motor 9.

[0018] The working principle of this embodiment is as follows: During the assembly of the iron tower, the first cylinder 2 and the second cylinder 3 are alternately placed around the central column 4, ensuring that the limiting ring 15 is placed inside the second cylinder 3, and that the threaded cylinder on the limiting ring 15 and the second cylinder 3 is aligned with the connecting rod 13. Then, the movement of the electric cylinder 6 drives the motor 9 to descend, and as the motor 9 descends, it drives the connecting rod 13 to extend outward, allowing the threaded head on the connecting rod 13 to engage with the threaded hole. Simultaneously, the first bevel gear 10 and the second bevel gear 12 mesh. The output of the motor 9 then drives the first bevel gear 10 to rotate. Through the meshing of the first bevel gear 10 and the second bevel gear 12, the second bevel gear 12 is rotated, thereby tightening the threaded head. The motor 9 then stops and locks, thus achieving a stable connection between the central rod and the cylinder. The above description is only a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
