Description

Technical Field

[0001] This utility model relates to the technical field of tank lifting devices, specifically to a metal storage tank lifting device. Background Technology

[0002] The assembly of metal storage tanks is usually carried out after the industrial plant structure is completed. Due to space constraints, the direct installation method cannot be used, so the inverted installation method is adopted to avoid the risks of working at heights. Traditional metal storage tanks are installed using the direct installation method, that is, after the tank bottom is installed, the tank wall is installed from bottom to top. Workers need to work at heights, which poses certain safety hazards. For example, the utility model patent with publication number CN216638674U discloses a storage tank lifting device. This device consists of a column and lifting lugs. The column is fixed by two diagonal support angle steels, with the angle between the diagonal support angle steels and the ground being 60°. The column lifting lugs and the metal storage tank body expansion ring lifting lugs are connected by a chain hoist and an electric hoist, and there is a certain angle between them. Therefore, the column lifting lugs often deform or break due to the large force, resulting in poor overall stability. At the same time, the height of the column cannot be freely extended or retracted, and the height of the column often needs to be adjusted according to the height of the tank, making the construction more complicated. Utility Model Content

[0003] The purpose of this utility model is to provide a metal storage tank lifting device, which solves the technical problems in the prior art caused by the inability to adjust the height of the column and the poor structural stability caused by the tilting of the column lifting lug and the expansion ring lifting lug.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A metal storage tank lifting device includes adjustable support columns, steel belts, plate-type lifting lugs, an electric hoist, expansion ring lifting lugs, a lower expansion ring, and a first reinforcing component. Multiple adjustable support columns are arranged on the tank bottom plate, located inside the tank body, with the first reinforcing component positioned between adjacent adjustable support columns. The steel belt is fixedly mounted on the top of the adjustable support columns. One plate-type lifting lug is fixedly mounted on each steel belt. An electric hoist is mounted on each plate-type lifting lug. The lower expansion ring is located at the bottom of the tank body, with multiple expansion ring lifting lugs arranged inside the lower expansion ring. A plate-type lifting lug is positioned directly above each expansion ring lifting lug.

[0005] Preferably, the adjustable support column includes a first column and a second column, the second column being slidably installed inside the first column, and multiple connecting holes are provided on both the first column and the second column. The relative positions of the first column and the second column are fixed by inserting pins into the corresponding connecting holes.

[0006] Preferably, two first reinforcement members are provided between two adjacent first columns.

[0007] Preferably, the steel strip is fixedly installed on the top of the second column.

[0008] Preferably, a second reinforcement member is provided between two adjacent second columns.

[0009] Preferably, a total of eight adjustable support columns are provided, and the eight adjustable support columns are evenly distributed along the inner circumference of the tank body.

[0010] Preferably, the electric hoist is connected to the plate-type lifting lug via a chain hoist.

[0011] In this utility model, the adjustable support column is made by adjusting the first column and the second column to achieve convenient adjustment of the overall height. It can be flexibly adjusted according to the lifting height requirements of different specifications of storage tanks without replacing the entire support structure. It is suitable for various tank construction scenarios and reduces equipment adaptation costs. At the same time, the eight support columns are evenly distributed along the inner circumference of the tank, which can provide uniform circumferential lifting points and lay the foundation for subsequent stable lifting.

[0012] Adjacent adjustable support columns form a basic frame through the first reinforcement component. When the second column extends significantly, an additional second reinforcement component can be installed to strengthen it, allowing multiple support columns to form a complete and rigid frame structure. This effectively resists the lateral force exerted by the tank on the support columns during lifting, preventing deformation or collapse of the support structure. Simultaneously, the frame's internal design eliminates diagonal bracing, maximizing the working space inside the tank. This facilitates operations such as tank docking and inspection by construction personnel, minimizing the impact of limited space on construction efficiency.

[0013] The lower expansion ring lifting lugs and plate lifting lugs are vertically aligned, ensuring that the electric hoist's chain and chain hoist remain vertical during lifting, completely avoiding the oblique force problems caused by misalignment of traditional lifting lugs. This prevents the lifting lugs from deforming or breaking due to additional lateral forces, extending the service life of components such as the lifting lugs and chains. It also reduces the risk of tank tilting or falling due to component damage, improving operational safety and reliability. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-3 The illustrated metal storage tank lifting device includes adjustable support columns 1, steel belts 2, plate-type lifting lugs 3, electric hoists 4, expansion ring lifting lugs 5, lower expansion rings 6, and a first reinforcing component 7. Multiple adjustable support columns 1 are arranged on the tank bottom plate 8, located inside the tank body. In this embodiment, eight adjustable support columns 1 are arranged in total, evenly distributed along the circumference of the tank body. This provides circumferentially uniform lifting points.

[0016] The adjustable support column 1 includes a first column 10 and a second column 11. The second column 11 is slidably installed inside the first column 10. Both the first column 10 and the second column 11 have multiple connecting holes 12. Pins are inserted into the corresponding connecting holes 12 to fix the relative positions of the first column 10 and the second column 11. During actual operation, the overall height of the first column 10 and the second column 11 is adjusted according to the actual height requirements.

[0017] A first reinforcement member 7 is fixedly installed between two adjacent adjustable support columns 1. Specifically, two first reinforcement members 7 are fixedly installed between two adjacent first columns 10. When the extension of the second column 11 is large, a second reinforcement member 13 is fixedly installed between two adjacent second columns 11 to reinforce the structure of the second column 11. Multiple adjustable support columns 1 are connected into a frame structure by several first reinforcement members 7 and second reinforcement members 13, which has good overall stability and no internal diagonal bracing structure, providing a relatively spacious working space.

[0018] The steel belt 2 is fixedly installed on the top of the adjustable support column 1, specifically, the steel belt 2 is fixedly installed on the top of the second column 11. A plate-type lifting lug 3 is fixedly installed on each steel belt 2. An electric hoist 4 is installed on each plate-type lifting lug 3, and the electric hoist 4 is connected to the plate-type lifting lug 3 via a chain hoist 9. During the lifting operation, multiple electric hoists 4 lift synchronously to ensure that the storage tank body is level and rises evenly.

[0019] The lower expansion ring 6 is located at the bottom inner side of the tank body, and multiple expansion ring lifting lugs 5 are provided inside the lower expansion ring 6; a plate-type lifting lug 3 is provided directly above each expansion ring lifting lug 5. The vertical positions of the expansion ring lifting lugs 5 and the plate-type lifting lugs 3 correspond to each other. During lifting, the chain and hoist 4 of the electric hoist 4 are in a vertical state, and will not deform or break due to the oblique force on the lifting lugs, thus improving the overall stability.

[0020] In another embodiment, to improve the stability of the tank lifting process, a guide assembly 14 is installed on the plate lifting lug 3 or the second column 11. The guide assembly 14 includes a support 140, a guide rod 141, a roller 142, and a spring 143. The support 140 is fixedly installed on the plate lifting lug 3 or the second column 11. One end of the guide rod 141 is slidably installed on the support 140. The spring 143 is disposed between the support 140 and the guide rod 141. The roller 142 is rotatably installed on the other end of the guide rod 141. The roller 142 is in contact with the inner wall of the tank. During the lifting process, multiple guide assemblies 14 can provide circumferential support to the inner wall of the tank, thereby improving the stability of the lifting.

[0021] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
