Description

Technical Field

[0001] This invention belongs to the field of television tower installation technology, and specifically relates to a method for assembling and lifting a super-tall television tower. Background Technology

[0002] A conventional steel tower consists of multiple structural steel columns, a tower crown, and a tower tip. The multiple structural steel columns form a ring-shaped support system that serves as the lower support for the tower crown. Multiple splicing blocks installed on the tower crown are fixed to the multiple structural steel columns to support the tower crown and the tower tip assembled on the tower crown to a set height.

[0003] In existing technologies, the installation of the tower crown and spire mostly relies on tower crane assembly or segmented installation processes. This process requires the erection of tower crane wall attachments to ensure stability, but its core drawback is that it cannot be adapted to the small cross-section, "heavy at the bottom and light at the top" ultra-high tower structure. Such towers have a significantly lower center of gravity, and are prone to attitude imbalance and overturning risks due to lateral forces during lifting. Traditional temporary stabilization measures can only provide simple positioning and cannot simultaneously ensure the reliability of anti-overturning and the accuracy of guidance. At the same time, high-altitude assembly operations are risky and have low assembly efficiency, and temporary measures consume a lot of materials, which cannot meet the construction quality and safety requirements of ultra-high towers. Therefore, we propose an assembly method and lifting mechanism for ultra-high TV towers to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a method for assembling and lifting the body of an ultra-high television tower, which solves the problems of high risk and low efficiency in assembling the tower body at high altitudes.

[0005] This invention is achieved through the following scheme: a method for assembling the body of an ultra-high television tower, comprising the following steps: S1. Multiple structural steel columns are installed in a ring at the designed location, forming a lifting area. S2. Provide multiple guide rails, connect the multiple guide rails to the inside of multiple structural steel columns respectively, and make each guide rail vertically set; S3. Assemble the crown, spire, and multiple splicing blocks in the lifting area, install the spire on the upper end of the crown, install multiple splicing blocks on the crown, provide multiple guide brackets, arrange the multiple guide brackets on the outer circumferential surface of the lower end of the crown, and make the multiple guide brackets slidably connected to multiple guide rails respectively; S4. Provide multiple lifting devices, connect the multiple lifting devices to the top of multiple structural steel columns respectively, and connect the drive ends of the multiple lifting devices to multiple splicing blocks respectively; S5. Simultaneously activate multiple lifters to raise the tower crown to the designed height; S6. Fix multiple splicing blocks to the corresponding structural steel columns.

[0006] A further improvement of the assembly method for the ultra-high TV tower body of the present invention is that each of the lifting devices includes a cable-type hydraulic lifting device fixed to the top of the corresponding structural steel column, and the steel strand on the cable-type hydraulic lifting device is connected to the corresponding splicing block. Before executing step S5, control all cable-driven hydraulic lifting devices to wind up the steel strands to a taut state, and when executing step S5, control all cable-driven hydraulic lifting devices to wind up the steel strands synchronously.

[0007] A further improvement of the assembly method for the ultra-high TV tower body of the present invention is that a first identification area is formed on the inner side of the upper end of each of the structural steel columns, and a second identification area is formed on the side of each splicing block facing the corresponding structural steel column. When raising the tower crown to the designed height, the second identification area on each of the splicing blocks is aligned with the first identification area on the corresponding structural steel column.

[0008] A further improvement of the assembly method for the ultra-high TV tower body of the present invention is that, in step S6, the second identification area on each splicing block is welded and fixed to the first identification area on the corresponding structural steel column.

[0009] A further improvement of the assembly method for the ultra-high TV tower body of the present invention is that, after performing step S6, it also includes the step of disassembling all the guide brackets, all the guide rails and all the lifting devices.

[0010] A further improvement of the assembly method for the ultra-high TV tower body of the present invention is that, before performing step S3, a jig is installed in the lifting area, and when performing step S3, the tower crown is first assembled on the jig, and then the tower tip and multiple splicing blocks are assembled.

[0011] A lifting mechanism for raising the tower crown to a designed height, comprising: Multiple guide rails are connected to the inner side of multiple structural steel columns, and each guide rail is set vertically. Multiple guide brackets are connected to the crown of the tower, and the multiple guide brackets are respectively arranged on the outer circumferential surface of the lower end of the crown and correspond one-to-one with multiple guide rails. Each of the guide brackets can be slidably connected to the corresponding guide rail. Multiple lifting devices are connected to the top of multiple structural steel columns, and the drive end of each lifting device is connected to multiple splicing blocks. The tower crown is lifted by synchronously starting multiple lifting devices.

[0012] A further improvement of the lifting mechanism of the present invention is that each of the lifting devices includes a cable-driven hydraulic lifting device fixed to the top of the corresponding structural steel column. The steel strands on the cable-driven hydraulic lifting device are connected to the corresponding splicing block. By simultaneously activating multiple cable-driven hydraulic lifting devices, the steel strands are wound up to achieve the lifting of the tower crown.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention lifts the tower crown by installing a lifting device at the top of the structural steel column, without relying on the tower crane to attach to the wall. During the lifting process, the guide bracket slides along the guide rail, which can ensure the stability of the lifting. Furthermore, the combination of the two can effectively prevent the tower crown from overturning during the lifting process, thus improving the installation accuracy. Attached Figure Description

[0018] To address the high risks and low efficiency of assembling tower bodies at high altitudes, this invention provides a method for assembling and lifting the body of an ultra-tall television tower. The following detailed description, in conjunction with accompanying drawings, illustrates this method for assembling and lifting the body of an ultra-tall television tower.

[0019] See Figures 1-3 As shown, a method for assembling the body of an ultra-tall TV tower includes: S1. Multiple structural steel columns 3 are installed in a ring at the designed location, forming a lifting area; S2. Provide multiple guide rails 5, connect the multiple guide rails 5 to the inner side of multiple structural steel columns 3 respectively, and make each guide rail 5 vertically arranged; S3, see reference Figure 3 As shown in Figure A, a tower crown 2, a tower tip 1, and multiple splicing blocks 4 are spliced ​​in the lifting area. The tower tip 1 is installed on the upper end of the tower crown 2, and multiple splicing blocks 4 are installed on the tower crown 2. Multiple guide brackets 6 with guide wheels are provided. The multiple guide brackets 6 are respectively arranged on the outer peripheral surface of the lower end of the tower crown 2, and the multiple guide wheels are respectively slidably connected to multiple guide rails 5. S4. Provide multiple lifting devices, connect the multiple lifting devices to the top of multiple structural steel columns 3 respectively, and connect the drive ends of the multiple lifting devices to multiple splicing blocks 4 respectively. S5, see reference Figure 3 As shown in Figure BD, multiple lifters are activated simultaneously to raise the tower crown 2 to the designed height; S6. Fix the multiple splicing blocks 4 to the corresponding structural steel columns 3.

[0020] This invention lifts the tower crown 2 by installing a lifting device on the top of the structural steel column 3, without relying on the tower crane to attach to the wall. During the lifting process, the guide wheel slides along the guide rail 5, which can ensure the stability of the lifting. Furthermore, the combination of the two can effectively prevent the tower crown 2 from overturning during the lifting process, thus improving the installation accuracy. Before lifting, the tower crown 2 and the tower tip 1 are assembled on the ground, avoiding disassembly at high altitude and greatly reducing the safety risks for workers.

[0021] Each of the lifting devices includes a cable-driven hydraulic lifting device 7 fixed to the top of the corresponding structural steel column 3, and the steel strand 8 on the cable-driven hydraulic lifting device 7 is connected to the corresponding splicing block 4. Before executing step S5, control all cable-driven hydraulic lifting devices 7 to wind up the steel strands 8 to a taut state, and when executing step S5, control all cable-driven hydraulic lifting devices 7 to wind up the steel strands 8 synchronously.

[0022] By adopting the above design, the steel strand 8 is kept taut before lifting to ensure that the tower crown 2 can rise stably during subsequent synchronous lifting, thereby improving the stability of the lifting process.

[0023] Each structural steel column 3 has a first identification area formed on the inner side of its upper end, and each splicing block 4 has a second identification area formed on the side facing the corresponding structural steel column 3. When raising the tower crown 2 to the designed height, the second identification area on each splicing block 4 is aligned with the first identification area on the corresponding structural steel column 3.

[0024] When performing step S6, the second identification area on each splicing block 4 is welded and fixed to the first identification area on the corresponding structural steel column 3.

[0025] By adopting the above design, when the second identification area on the splicing block 4 is aligned with the first identification area on the corresponding structural steel column 3, it indicates that the tower crown 2 has risen to the designed height; then the structural steel column 3 and the splicing block 4 are fixed by welding, or other reinforcement methods such as bolt connection can be used.

[0026] Among them, see Figure 3As shown in Figure E, after step S6 is completed, the following steps are also included: disassembling all guide brackets 6, all guide rails 5, and all lifters.

[0027] By adopting the above design, each structure can be disassembled after construction, making it convenient for reuse.

[0028] Before performing step S3, a frame 9 is installed in the lifting area. When performing step S3, the crown 2 is first spliced ​​on the frame, and then the top 1 and multiple splicing blocks 4 are spliced.

[0029] By setting up the frame 9, the bottom height of the tower crown 2 is raised, which facilitates the installation of the guide bracket 6.

[0030] A lifting mechanism for raising the tower crown 2 to a designed height, comprising: Multiple guide rails 5 are connected to the inner side of multiple structural steel columns 3 respectively, and each guide rail 5 is arranged vertically; Multiple guide brackets 6 are connected to the crown 2, and the multiple guide brackets 6 are respectively arranged on the outer circumferential surface of the lower end of the crown 2 and correspond one-to-one with multiple guide rails 5. Each guide bracket 6 is connected to a guide wheel that is slidably connected to the corresponding guide rail 5. Multiple lifting devices are connected to the top of multiple structural steel columns 3 respectively. The drive end of each lifting device is connected to multiple splicing blocks 4 respectively. By activating multiple lifting devices simultaneously, the tower crown 2 can be lifted.

[0031] Each lifting device includes a cable-driven hydraulic lifting device 7 fixed to the top of the corresponding structural steel column 3. The steel strands 8 on the cable-driven hydraulic lifting device 7 are connected to the corresponding splicing block 4. By simultaneously starting multiple cable-driven hydraulic lifting devices 7 to wind up the steel strands 8, the tower crown 2 can be lifted.
