Description

Technical Field

[0001] This invention relates to the field of steel structure tower and mast pre-assembly technology, and in particular to a pre-assembly structure and method for all-bolted steel structure tower and mast. Background Technology

[0002] Steel structure towers and masts are widely used in communications, power, and other fields, and their structural stability and installation accuracy are crucial for their subsequent use. Traditionally, steel structure towers and masts are assembled using welding connections, which has several drawbacks. Firstly, welding is prone to deformation, leading to dimensional deviations in the tower and mast structure, affecting overall verticality and stability. Furthermore, welding quality is highly dependent on the welder's skill level and on-site environmental factors, making it difficult to guarantee quality. Secondly, welding is inefficient, requiring specialized welding equipment and personnel on-site, and post-weld flaw detection and other procedures, increasing construction costs and time. In addition, welded steel structure towers and masts are difficult to maintain, disassemble, and recycle, making it difficult to meet the requirements of green construction and sustainable development. With the development of technology, some steel structure towers and masts adopt flange docking and then use bolt connection instead of welding. However, the existing bolt connection structure has the problem of inaccurate flange docking positioning during the pre-assembly process, resulting in low pre-assembly accuracy. A lot of adjustment work is still required during on-site assembly, which cannot give full play to the advantages of bolt connection in terms of efficiency and convenience. Therefore, it is necessary to design a pre-assembly structure and assembly method for all-bolted steel structure towers and masts to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a pre-assembled structure and method for all-bolted steel tower masts to solve the above-mentioned problems.

[0004] The above-mentioned technical objective of this invention is achieved through the following technical solution: a pre-assembled all-bolted steel tower mast structure, comprising: Steel structure tower mast pre-assembly flange one and steel structure tower mast pre-assembly flange two, wherein a guide assembly mechanism is provided on steel structure tower mast pre-assembly flange one and steel structure tower mast pre-assembly flange two; The guide assembly mechanism includes a guide post, a guide cone, and a collar. The guide cone is fixedly installed on the top of the guide post, and the collar is sleeved on the outside of the guide post.

[0005] A further configuration of the present invention is as follows: the guiding assembly mechanism further includes a first splicing block, a first splicing groove, a first base plate, a rotating shaft, a second base plate, a first positioning block, and a synchronizing element. The first splicing block is fixedly connected to the guide column. The first splicing groove is formed on the first pre-assembly flange of the steel structure tower mast. The first splicing block and the first splicing groove are engaged. The first base plate is fixedly installed at the bottom of the guide column. The rotating shaft is rotatably installed on the first base plate. The second base plate is fixedly installed at the bottom of the first splicing block. The first positioning block is slidably installed on the second base plate. The first positioning block is engaged with the first pre-assembly flange of the steel structure tower mast. The rotating shaft has a bidirectional thread on its outer side. The bidirectional thread is threadedly connected to the first positioning block. The synchronizing element is fixedly installed on the top of the first splicing block.

[0006] A further configuration of the present invention is as follows: the guiding assembly mechanism further includes a connecting seat, a second splicing groove, a second splicing block, a slider, a spring, a second positioning block, and a support member. The connecting seat is fixedly connected to the second pre-assembly flange of the steel structure tower mast. The second splicing groove is formed on the connecting seat. The second splicing block is engaged with the second splicing groove. The second splicing block is fixedly connected to a collar. A sliding groove is formed at the bottom of the second splicing block. The slider is slidably installed in the sliding groove. The spring is fixedly installed between the slider and the side wall of the sliding groove. The slider is fixedly connected to the second positioning block. The slider is engaged with a synchronizing member. The support member is fixedly installed at the bottom of the second splicing block. The second positioning block is slidably installed on the support member. The second positioning block is engaged with the connecting seat.

[0007] A further feature of the present invention is that a synchronization groove is provided at the bottom of the slider, and the synchronization component is engaged with the synchronization groove.

[0008] A further feature of the present invention is that a synchronization hole is provided at the top of one of the splicing blocks, and a synchronization component is slidably installed in the synchronization hole.

[0009] A further feature of the present invention is that bolt holes are provided on the top of both the first and second pre-assembly flanges of the steel structure tower mast.

[0010] A further provision of the present invention is that: a positioning groove is provided on one side wall of the splicing groove, and a positioning block is engaged with the positioning groove; a positioning groove is provided on the side wall of the splicing groove, and a positioning block is engaged with the positioning groove.

[0011] An assembly method for a pre-assembled all-bolted steel tower mast structure according to any of the above-mentioned methods includes the following steps: Step S1: First, move splicing block one into splicing groove one, rotate the shaft so that positioning block one is engaged in positioning groove one, pull the slider so that the slider compresses the spring, then move splicing block two into splicing groove two, release the slider, the spring returns to its original position and drives the slider to move so that positioning block two is engaged in positioning groove two. In this way, the guide column is installed on the pre-assembly flange one of the structural tower mast, and the collar is installed on the pre-assembly flange two of the structural tower mast. Step S2: Lift the second pre-assembled flange of the structural tower mast using external lifting equipment, and then slowly place the second pre-assembled flange of the structural tower mast onto the first pre-assembled flange of the structural tower mast. During this process, the guide cone guides the collar, causing the collar to move into the outside of the guide column until the synchronizing element is inserted into the synchronizing groove, which facilitates the guiding and positioning process. Step S3: After the steel structure tower mast pre-assembly flange one and steel structure tower mast pre-assembly flange two are installed, rotate the shaft to move the positioning block one out of the positioning groove one. During this process, the positioning block one drives the synchronous component to move, so that the slider squeezes the spring until the positioning block two moves out of the positioning groove two. Then pull down the guide column to remove the guide assembly mechanism for multiple cycles of use.

[0012] The beneficial effects of this invention are: 1. The present invention, through its guided assembly mechanism, addresses the issue that traditional welding methods are prone to welding deformation, leading to dimensional deviations in the tower and mast structure and affecting overall verticality and stability. The present invention employs a fully bolted connection and a high-precision guided assembly mechanism, completely eliminating the welding process. Through the precise guidance of the guide cone and collar, and the accurate positioning of the synchronizing components and synchronizing grooves, the dimensional deviation problem caused by welding deformation is fundamentally eliminated, significantly improving the stability and installation accuracy of the tower and mast structure. 2. The present invention achieves high-precision positioning in the pre-assembly stage through the set guide assembly mechanism. After on-site assembly, the structure is tightly connected and stable. During later maintenance, the bolts can be directly disassembled for inspection. During disassembly, each component can be quickly separated, and the guide assembly mechanism can be disassembled and reused. Attached Figure Description

A sliding groove is opened at the bottom of the second splicing block 16. The slider 18 is slidably installed in the sliding groove. The spring 19 is fixedly installed between the slider 18 and the side wall of the sliding groove. The slider 18 is fixedly connected to the second positioning block 20. The slider 18 is engaged with the synchronization member 12. The support member 21 is fixedly installed at the bottom of the second splicing block 16. The second positioning block 20 is slidably installed on the support member 21. The second positioning block 20 is engaged with the connecting seat 14.

[0030] The above structure facilitates the installation of the collar 17 on the pre-assembled flange 2 of the steel structure tower mast, and makes it easy to remove after use.

[0031] Specifically, the bottom of the slider 18 is provided with a synchronization groove 22, and the synchronization component 12 is engaged with the synchronization groove 22. The top of the splicing block 6 is provided with a synchronization hole 13, and the synchronization component 12 is slidably installed in the synchronization hole 13. It should be added that this facilitates synchronous movement.

[0032] Specifically, both the top of the pre-assembled flange 1 and the pre-assembled flange 2 of the steel structure tower mast are provided with bolt holes 3, which facilitates installation.

[0033] Specifically, a positioning groove 1 is provided on the side wall of splicing groove 1 7, and positioning block 1 11 is engaged with positioning groove 1. A positioning groove 2 is provided on the side wall of splicing groove 2 15, and positioning block 2 20 is engaged with positioning groove 2. It should be added that this makes positioning processing convenient.

[0034] An assembly method for a pre-assembled all-bolted steel tower mast structure according to any of the above includes the following steps: Step S1: First, move splicing block 16 into splicing groove 17, rotate shaft 9 so that positioning block 11 is engaged in positioning groove 1, pull slider 18 so that slider 18 compresses spring 19, then move splicing block 26 into splicing groove 25, release slider 18, spring 19 resets and drives slider 18 to move so that positioning block 20 is engaged in positioning groove 2. In this way, guide column 4 is installed on structural tower mast pre-assembly flange 11, and collar 17 is installed on structural tower mast pre-assembly flange 22. Step S2: Lift the pre-assembled flange 2 of the structural tower mast using external lifting equipment, and then slowly place the pre-assembled flange 2 of the structural tower mast onto the pre-assembled flange 1 of the structural tower mast. During this process, the guide cone 5 guides the collar 17, so that the collar 17 moves into the outside of the guide column 4 until the synchronizing element 12 is inserted into the synchronizing groove 22, which facilitates the guiding and positioning process. Step S3: After the steel structure tower mast pre-assembly flange 1 and steel structure tower mast pre-assembly flange 2 are installed, rotate the shaft 9 so that the positioning block 11 moves out of the positioning groove 1. During this process, the positioning block 11 drives the synchronous component 12 to move, so that the slider 18 squeezes the spring 19 until the positioning block 20 moves out of the positioning groove 2. Then pull down the guide column 4 to remove the guide assembly mechanism for repeated use.

[0035] Working principle: After the splicing block 16 is inserted into the splicing groove 7 of the pre-assembled flange 1 of the steel structure tower mast, the rotating shaft 9 is rotated. The bidirectional thread on its outer side drives the positioning block 11 to slide along the bottom plate 10 until it is inserted into the positioning groove 1 on the side wall of the splicing groove 7, thus fixing the guide column 4 to the pre-assembled flange 1 of the steel structure tower mast. When the collar 17 is assembled with the connecting seat 14 of the pre-assembled flange 2 of the steel structure tower mast through the splicing block 26, the slider 18 is pulled to compress the spring 19, and the splicing block 26 is inserted into the splicing groove 25. After the slider is released, the spring returns to its original position and pushes the positioning block 20 into the positioning groove 2, thus fixing the collar 17 to the pre-assembled flange 2 of the steel structure tower mast. At this time, the synchronizing element 12 passes through the synchronizing hole 13, and its top and the synchronizing groove 22 at the bottom of the slider 18 remain in a non-clamped state. When hoisting the pre-assembled flange 2 of the steel structure tower mast, the guide cone 5 is inserted into the collar 17. The collar 17 slides down the guide post 4 using the guiding effect of the cone surface until the synchronizing element 12 is engaged in the synchronizing groove 22. At this time, the bolt holes 3 of the pre-assembled flange 1 and the pre-assembled flange 2 of the steel structure tower mast are precisely aligned, realizing the pre-assembly positioning. After the flange docking is completed, the rotating shaft 9 is rotated in the opposite direction, and the positioning block 11 is disengaged from the positioning groove 1. At the same time, the synchronizing element 12 drives the slider 18 to compress the spring 19, causing the positioning block 20 to disengage from the positioning groove 2. At this time, the guide post 4 and the collar 17 lose their positioning constraints and can be disassembled and recycled as a whole for reuse.
