[0035] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0036] like Figures 1 to 3 As shown, the present invention provides a batch construction device for single-column composite cylinders, which mainly includes a circumferential positioning mechanism 1 and a compartment template mechanism 3. The circumferential positioning mechanism 1 and the compartment template mechanism 3 can assist in the batch construction of single-column composite cylinders.

[0037] Combination Figure 4As shown, the ring positioning mechanism 1 comprises a center cylinder 101 and telescopic rods 102. The center cylinder 101 is a cylindrical structure, which is fixed to the ground by bolts or steel nails. Six telescopic rods 102 are evenly distributed around the center cylinder 101 and extend radially, and the included angle between adjacent two telescopic rods 102 is 60°. Each telescopic rod 102 can be extended or retracted outward from the center cylinder 101. The number of telescopic rods 102 is determined according to the size of the single-column composite cylinder, and is generally selected in the range of 6-9.

[0038] In combination Figure 5 As shown, the cabin dividing template mechanism 3 comprises ring bodies 301, limiting clamping plates 302, sliding rails 303 and sliding bodies 304.

[0039] The two ring bodies 301 are the same in structure and are arranged in parallel vertically. Each ring body 301 is divided into a plurality of arc-shaped sections, and the number of arc-shaped sections is the same as the number of cabin dividing plates 4 of the single-column composite cylinder, which is six in this embodiment.

[0040] Adjacent two arc-shaped sections of the same ring body 301 are provided with a gap, and each arc-shaped section is provided with a limiting clamping plate 302 arranged vertically at each end, which extends substantially along the radial direction of the ring body 301. One end of the limiting clamping plate 302 is fixedly connected with the end of the arc-shaped section, and the other end is suspended.

[0041] The arc-shaped section is preferably made of a steel plate with the same thickness and width as the limiting clamping plate 302, and the two can be welded or integrally formed.

[0042] All limiting clamping plates 302 connected by the two ring bodies 301 are the same in size and correspond in position vertically.

[0043] Thus, the cabin dividing plates 302 between adjacent two arc-shaped sections form a group, the limiting clamping plates 302 in each group are substantially parallel, and the gap is used for inserting the cabin dividing plates 4 of the single-column composite cylinder. The upper and lower parts of the cabin dividing plates 4 are respectively limited and fixed by the two groups of limiting clamping plates 302 corresponding vertically.

[0044] The upper and lower ring bodies 301 are connected by a plurality of sliding rails 303 arranged vertically, which are preferably evenly distributed around the outside of the ring body 301. The number of sliding rails 303 is also the same as the number of cabin dividing plates 4 of the single-column composite cylinder, which is six in this embodiment.

[0045] Each slide rail 303 is connected with two arc segments corresponding to the upper and lower positions respectively. Preferably, each slide rail 303 is located at the middle position of the arc segment. The slide rail 303 is fixedly connected with the lower ring body 30 and connected with the upper ring body 30 through a sliding body, so that the upper ring body 30 can slide along the slide rail 303 and be fixed at any height of the slide rail 303, thereby adapting to various heights of the compartment plate 4.

[0046] Further, the lower part of the slide rail 303 is welded with the lower ring body 30, and a bottom plate is welded on the bottom surface, and the slide rail 303 is fixed to the ground through bolts or steel nails passing through the bottom plate. In this way, the positions of each arc segment in the lower ring body 30 are fixed and cannot move, thereby avoiding the shifting and deviation of the compartment template mechanism 3 during the installation of the compartment plate 4. In addition, the axial position and radius of the lower ring body 30 are determined by the ring positioning mechanism 1 before installation.

[0047] Further, the sliding body 304 can be designed as any structure capable of fixing the slide rail 303 and the arc segment at the same time, and has a detachable function. In the embodiment, the slide rail 303 is designed as a cylindrical vertical rod, and the sliding body 304 is designed as a pipe sleeve. The middle part of the pipe sleeve is sleeved outside the slide rail 303, and the two ends are fixed with the arc segment of the upper ring body 30 through bolts. When the bolts are loosened, the pipe sleeve can drive the upper ring body 30 to move up and down along the slide rail 303.

[0048] The single-column composite cylinder batch construction method based on the single-column composite cylinder batch construction device includes the following steps:

[0049] (1) The center cylinder 101 of the ring positioning mechanism 1 is fixed to the ground, and the length of the telescopic rod 102 is adjusted so that the outer diameter of the ring positioning mechanism 1 is consistent with the inner diameter of the ring body 301 of the compartment template mechanism 3. Based on the axis and outer diameter of the ring positioning mechanism 1, the slide rail 303 in the compartment template mechanism 3 is fixed to the ground together with the lower ring body 301.

[0050] The outer diameter of the ring positioning mechanism 1 is the distance from the end of the telescopic rod 102 to the axis of the center cylinder 101, and the axis of the ring positioning mechanism 1 is the axis of the center cylinder 101.

[0051] (2) The position of the center cylinder 101 of the ring positioning mechanism 1 is unchanged, and the length of the telescopic rod 102 is adjusted so that the outer diameter of the ring positioning mechanism 1 is consistent with the inner diameter of the center cylinder 2 of the single-column composite cylinder. Based on the axis and outer diameter of the ring positioning mechanism 1, the center cylinder 2 of the single-column composite cylinder is constructed.

[0052] (3) After the upper ring body 301 is positioned according to the height of the compartment plate 4, it is fixedly connected to each slide rail 303 through the sliding body 304, and the compartment template mechanism 3 is assembled.

[0053] (4) Insert the compartment plates 4 one by one between the corresponding sets of limiting clamps 302 of the upper and lower annular bodies 301, and weld the compartment plates 4 to the central cylinder 101.

[0054] (5) After all the compartment plates 4 are welded to the central cylinder 101, the cylinder wall 5 is welded to each compartment plate 4.

[0055] (6) Weld the top cover 6 to each compartment plate 4.

[0056] like Figures 6 to 8 As shown, in a preferred embodiment, the batch construction method of the single-column composite cylinder of the present invention divides the top cover 6 into multiple identical sector-shaped blocks. The number of sector-shaped blocks is the same as the number of compartment plates 4 of the single-column composite cylinder, which is six in this embodiment. Two connecting pieces 7 are provided in the middle of each sector-shaped block. The connecting pieces 7 are perpendicular to the sector-shaped block and correspond to the top sides of each compartment plate 4. Each compartment plate 4 has evenly distributed bolt holes on its top, and each connecting piece 7 also has bolt holes matching those of the compartment plate 4. During installation, the top of the compartment plate 4 is first inserted between the two connecting pieces 7 of each sector-shaped block, and the sector-shaped blocks of the top cover 6 are then connected to the top of the compartment plates 4 by bolts and welding. After all the sector-shaped blocks are installed, they are welded together to form a sealed whole. The last sector-shaped block installed in the top cover 6 may not be connected to the compartment plates 4 but can be directly welded to other sector-shaped blocks. This not only makes the construction process of single-column composite tubes faster and more convenient, but also enhances the overall rigidity of single-column composite tubes.

[0057] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many specific modifications under the guidance of the present invention without departing from the spirit of the invention and the scope of protection of the claims, and these modifications all fall within the scope of protection of the present invention.
