[0034] As Figures 1 to 4 shown, the present invention provides a platform for storage tank assembly, including a base 100, a support assembly, a traveling assembly 200, and a climbing assembly 300;

[0035] The support assembly is placed on a fixed surface, and an assembly space is formed inside the support assembly. The base 100 is fixedly arranged at the bottom of the assembly space, and the base 100 is used to place the central air ballast and the lift of the storage tank;

[0036] The traveling assembly 200 is arranged along the circumferential direction of the support assembly at one end of the support assembly facing away from the base 100, and the climbing assembly 300 is arranged on the side wall of the support assembly, and the climbing assembly 300 extends along the height direction of the support assembly.

[0037] In this embodiment, the platform for assembling a storage tank includes a base 100, a support assembly, a walking assembly 200 and a climbing assembly 300. After the platform is assembled in a storage tank production workshop or factory, an assembly space is formed inside the support assembly. The central gas ballast and the liquid lifter of the storage tank are positioned and fixed on the base 100 located at the bottom of the assembly space. The internal components of the remaining storage tanks are assembled in order from bottom to top, from inside to outside. The walking assembly 200 arranged along its own circumference at one end of the support assembly away from the base 100 can facilitate assemblers to stand and walk, and assemble components located at a high place. The climbing assembly 300 can be used to climb to the walking assembly 200, which is very convenient. By using this platform, installation in a limited indoor space can be converted into assembly within the assembly space, reducing the cross-operation with the construction unit at the construction site during the traditional method of on-site storage tank production, and also facilitating assembly work at a high place, greatly improving the situation where the construction progress is affected by the limited space in the equipment room, thereby effectively shortening the construction period and improving the assembly construction efficiency.

[0038] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the support assembly includes multiple columns 400 and multiple support beams 401. The columns 400 and the support beams 401 correspond to each other one by one. The multiple support beams 401 are evenly spaced and arranged in a circular shape on the fixed surface. One end of each column 400 is vertically bolted to the support beam 401. The multiple columns 400 and the support beams 401 enclose an assembly space.

[0039] In this embodiment, multiple columns 400 and multiple supporting beams 401 correspond one to one. Preferably, the columns 400 and the supporting beams 401 are made of H-shaped steel, and screw holes are reserved during production to facilitate rapid disassembly and assembly by bolts. After each column 400 is bolted to the corresponding supporting beam 401, the two are perpendicular to each other. Since multiple supporting beams 401 are evenly spaced and arranged in a circular shape on the fixed surface, the bolted columns 400 and supporting beams 401 together enclose an assembly space. The base 100 is provided at the bottom of the assembly space and is connected to the top wall of the supporting beam 401 by bolts, thereby forming a support foundation for the entire platform, so that the limited indoor space at the construction site can be converted into an assembly space for installation, thereby reducing cross-operations with civil engineering at the construction site, reducing cross-impacts, and improving construction efficiency.

[0040] The assembly space formed by the spaced columns 400 and the supporting beams 401 is hollowed out in both the circumference and the top, making it more convenient to hoist the tank components into place, ensuring assembly from bottom to top and from the inside out, making it easier to detect the welds after assembly, thereby effectively shortening the construction period and improving construction efficiency.

[0041] Among them, preferably, the number of columns 400 and supporting beams 401 is set to eight to ensure that the enclosed assembly space is sufficient for assembly operations. Of course, it can also be six, ten or other numbers. The purpose does not deviate from the design concept of the present invention and should fall within the scope of protection of the present invention.

[0042] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the support assembly further includes an oblique support column 402 , one end of which is connected to the end of the support beam 401 facing away from the column 400 , and the other end of the oblique support column 402 is connected to the side wall of the column 400 .

[0043] In this embodiment, a diagonal support column 402 is further installed on the side of each corresponding column 400 and supporting beam 401 facing away from the assembly space. Preferably, screw holes are reserved in the diagonal support column 402, the column 400 and the supporting beam 401 respectively, so that the diagonal support column 402 can be bolted to the column 400 and the supporting beam 401 respectively, that is, one end of the diagonal support column 402 is connected to the end of the supporting beam 401 facing away from the column 400, and the other end of the diagonal support column 402 is connected to the side wall of the column 400, so that a triangle is formed between the diagonal support column 402, the column 400 and the supporting beam 401. The triangle is stable, and the stability of the connection between the column 400 and the supporting beam 401 can be effectively guaranteed by installing the diagonal support column 402.

[0044] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, reinforcing rods 403 are provided between adjacent columns 400 .

[0045] In this embodiment, since the columns 400 and the supporting beams 401 cooperate to enclose an assembly space, the position of the columns 400 needs to be limited to prevent the assembly period from being affected due to the position of the columns 400 during the assembly of the storage tank. Therefore, reinforcing rods 403 are provided between adjacent columns 400 to limit the position of the columns 400 to improve stability.

[0046] According to an embodiment provided by the present invention, Figure 1 and Figure 3 As shown, the walking assembly 200 includes a pedal 201 , which is arranged along the circumference of the assembly space at one end of the column 400 away from the supporting beam 401 .

[0047] In this embodiment, the pedal 201 is arranged along the circumference of the assembly space, and the pedal 201 is respectively bolted to one end of each column 400 facing away from the support cross beam 401, so that assembly workers can handle related operations on the pedal 201, enabling the platform for storage tank assembly provided in this embodiment to have the function of working at height.

[0048] Assembly workers can perform welding and other related operations within the assembly space and on the pedal 201, thus avoiding the situation where the welding space is insufficient and the welding difficulty is increased due to interference from other components in the indoor construction site. After assembling the platform in the production factory, welding is directly carried out, greatly increasing the welding space, thereby reducing the welding difficulty and improving the welding quality.

[0049] According to an embodiment provided by the present invention, as Figure 1 and Figure 3 shown, the walking assembly 200 further includes a guardrail 202, and the guardrail 202 is arranged along the circumference of the edge of the pedal 201 facing away from the assembly space.

[0050] In this embodiment, the guardrail 202 is arranged along the circumference of the edge of the pedal 201 facing away from the assembly space, that is, the guardrail 202 is in the same direction as the pedal 201, the guardrail 202 is perpendicular to the pedal 2 over the assembly space, and the height of the guardrail 202 can be set according to actual use requirements and will not be elaborated here. By setting the guardrail 202, the safety performance of assembly workers working at height on the pedal 201 can be ensured, and the safety risk can be greatly reduced.

[0051] According to an embodiment provided by the present invention, as Figure 1 and Figure 3 shown, the walking assembly 200 further includes a plurality of support members 203, the support members 203 correspond to the columns 400 one by one, one end of the support member 203 is fixedly connected to the column 400, the support member 203 is perpendicular to the column 400, and the pedal 201 is placed on the support member 203.

[0052] In this embodiment, a support member 203 is provided at the top of the column 400. Preferably, the relative position of the support member 203 is fixed to the column 400 through a pin. A strengthening rod is arranged between the bottom surface of the support member 203 and the column 400, and both ends of the strengthening rod are respectively connected to the bottom wall of the support member 203 and the side wall of the column 400 to enhance the stability of the support member 203, and then the pedal 201 is fixed to the support member 203 through a fastener.

[0053] According to an embodiment provided by the present invention, as Figure 1 and Figure 4 shown, the climbing assembly 300 includes a ladder 301, and the ladder 301 is arranged on the side wall of the column 400 facing away from the assembly space.

[0054] In this embodiment, in order to facilitate the assemblers to climb smoothly to the pedal 201, a ladder 301 is provided on the side wall of the column 400 facing away from the assembly space. The extending direction of the ladder 301 is consistent with the length direction of the column 400. The assemblers use the ladder 301 to climb onto the pedal 201 to handle relevant assembly operations.

[0055] According to an embodiment provided by the present invention, as Figure 1 and Figure 4 shown, the climbing assembly 300 further includes a protective cage 302, and the protective cage 302 is arranged outside the ladder 301.

[0056] In this embodiment, in order to ensure the safety of the assemblers during the climbing process along the ladder 301 to the pedal 201, a protective cage 302 is circumferentially arranged outside the ladder 301 to enhance the overall safety of the ladder 301 and reduce the safety risk of working at heights.

[0057] According to an embodiment provided by the present invention, as Figure 1 shown, the base 100 includes a bottom plate 101, a first support 102 and a second support 103;

[0058] The bottom plate 101 is arranged at the bottom of the assembly space and is fixedly connected to a plurality of support crossbeams 401 respectively. The first support 102 and the second support 103 are both installed on the bottom plate 101. The first support 102 is used to fix the central air ballast, and the second support 103 is used to fix the lift pump.

[0059] In this embodiment, the bottom plate 101 is arranged at the bottom of the assembly space. The bottom plate 101 is fixed to the support crossbeam 401 by bolts. The first support 102 and the second support 103 are bolted to the bottom plate 101 through the pre - reserved screw holes on the bottom plate 101. After the platform is assembled, the central air ballast component of the storage tank is positioned on the first support 102, and then the lift pump component of the storage tank is placed on the second support 103. Preferably, scale lines are correspondingly arranged on the first support 102 and the second support 103 to ensure that the positions of the central air ballast and the lift pump meet the installation allowable error. Then, the remaining internal components of the storage tank are assembled in sequence from bottom to top and from inside to outside, and non - destructive testing of the welding seams is carried out to ensure the quality of the storage tank.

[0060] The central air ballast and the lift pump are positioned by the first support 102 and the second support 103 to ensure that the installation positioning accuracy is controlled within ±10 mm and the allowable difference in the verticality of the storage tank body installation is not greater than 9.5 mm.
