Description

Technical Field

[0001] This invention belongs to the field of membrane tank construction technology, and particularly relates to a clamping device and a method for installing corrugated plates in membrane tanks. Background Technology

[0002] Compared to traditional 9% nickel-steel prestressed concrete full-containment tanks, the main difference in the design of membrane-type LNG storage tanks lies in the clear separation of tank structure, insulation, and airtightness functions. This allows for the optimization of each component and effectively prevents accidents. At the same time, membrane-type LNG storage tanks also possess unique advantages such as large net storage capacity, simple construction process, short construction period, and low construction cost. As my country's LNG market gradually matures, pursuing tank type diversification, low construction costs, and short construction periods has become the mainstream trend.

[0003] The Hebei Hejian LNG Peak-Shaving Reserve Project of Huagang Gas Group is the first onshore membrane-type LNG storage tank in China. During construction, previous shipbuilding experience could not be fully applied. For example, shipbuilding typically uses scaffolding inside the tank for auxiliary work, but this land-based tank project used suspended platform work, with only one platform available for each task, impacting many aspects of the work to varying degrees. The installation of corrugated plates, due to their large number and strict installation sequence requirements, resulted in low installation efficiency in the tank wall area, severely affecting the work progress and extending the overall construction cycle.

[0013] The first step is to place the corrugated sheet on the assembly platform and then splice and fix the corrugated sheets together according to the overlap requirements between them.

[0014] The second step is to form a large corrugated board panel after the corrugated boards are assembled on the assembly platform.

[0015] The third step involves preparing a clamping device for installing the corrugated sheet of the film tank. This device includes a clamping module, a connecting module, a handle module, and a lifting module. The clamping module clamps the corrugated sections of the corrugated sheet. The clamping module is connected to the handle module via the connecting module, and the lifting module is mounted on the upper part of the handle module.

The lifting ring is connected to the upper fixed plate. The shackle is connected to the lifting ring. The clamping device for installing the corrugated plate of the film tank is used to lift the corrugated plate splicing large plate onto the film tank wall for installation.

[0016] The fourth step is to select three corrugated sections on the end face of the corrugated plate splicing plate as lifting points, fix the clamping device for installing the corrugated plate of the film tank to the selected lifting points on the corrugated plate splicing plate, and then use a small crane to connect and fix it to the clamping device for installing the corrugated plate of the film tank to the corresponding position on the film tank wall and install the corrugated plate on the film tank wall.

[0017] The fifth step is to hoist the corrugated plate splicing large plate onto the membrane tank wall, then weld the four sides of the corrugated plate splicing large plate to the membrane tank wall to complete the installation of the corrugated plate splicing large plate on the membrane tank wall.

[0018] Step 6: Repeat steps 1 through 5 to complete the installation of the corrugated plates on the wall of the membrane tank.

[0019] The splicing platform in the first step above includes support legs and a mounting plane. The support legs are perpendicularly connected to the lower end face of the mounting plane.

[0020] The specific steps for splicing corrugated sheets into a large corrugated sheet assembly in the second step above are as follows: After the corrugated sheets are spliced ​​on the splicing platform according to the overlap requirements between the corrugated sheets, spot welding is performed at 50mm intervals at the splicing points to fix the adjacent corrugated sheets. After the spot welding of the adjacent corrugated sheets is completed to form the large corrugated sheet assembly, continuous welding is used at the splicing points to fix the adjacent corrugated sheets, thus completing the welding of the large corrugated sheet assembly.

The corrugated sections are clamped and fixed by rotating the handle and moving the jacking clamp. The lifting straps are connected to the shackles respectively. Then the lifting straps are connected to the small crane to lift the corrugated plate splicing large plate. When the corrugated plate splicing large plate is lifted by the small crane, the corrugated plate splicing large plate is parallel to the membrane tank wall.

[0022] In the fifth step above, when the corrugated plate splicing plate is welded to the wall of the membrane tank around its perimeter, the amount of adhesion around the perimeter of the corrugated plate splicing plate shall not be less than the sum of the amount of adhesion between all individual corrugated plates in the corrugated plate splicing plate and the wall of the membrane tank.

[0042] The third step is to prepare a clamping device for installing the corrugated sheet of the film tank. This device includes a clamping module, a connecting module, a handle module, and a hoisting module. The clamping module clamps the corrugated sections of the corrugated sheet.

This simultaneously achieves the fixing of the corrugated section of the corrugated plate and the hoisting of the corrugated plate by the clamping device, improving the efficiency of corrugated plate installation.

[0043] The fourth step is to select three corrugated sections on the end face of the corrugated plate splicing plate 56 as lifting points, fix the clamping device for installing the corrugated plate of the film tank to the selected lifting points on the corrugated plate splicing plate 56 respectively, and then use the small crane 55 to connect and fix it to the clamping device for installing the corrugated plate of the film tank to lift the corrugated plate splicing plate 56 to the corresponding position on the film tank wall and install the corrugated plate on the film tank wall.

[0044] The fifth step is to hoist the corrugated plate splicing plate 56 onto the wall of the film tank, and then weld the four sides of the corrugated plate splicing plate 56 to the wall of the film tank to complete the installation of the corrugated plate splicing plate 56 on the wall of the film tank.

At the same time, it avoids the problem of corrugated sheet deformation caused by welding during corrugated sheet splicing, thus improving the quality of corrugated sheet splicing installation.

[0047] The specific steps for splicing corrugated plates into corrugated plate splicing large plate 56 in the second step above are as follows: After the corrugated plates are spliced ​​on the splicing platform according to the overlap requirements between the corrugated plates, spot welding is performed at intervals of 50mm at the splicing points between the corrugated plates to weld and fix the adjacent corrugated plates. After the spot welding of the adjacent corrugated plates is completed to form the corrugated plate splicing large plate 56, continuous welding is used at the splicing points between the corrugated plates to complete the welding and fixation of the adjacent corrugated plates, thus completing the welding of the corrugated plate splicing large plate 56.

[0048] The specific steps for hoisting the corrugated sheet splicing large plate 56 in the fourth step above are as follows: Select the corrugated joint at the junction of one-third of the length direction and one-third of the width direction of the corrugated sheet splicing large plate 56 as the first hoisting point; select the corrugated joint at the junction of two-thirds of the length direction and one-third of the width direction of the corrugated sheet splicing large plate 56 as the second hoisting point; select the corrugated joint at the junction of one-half of the length direction and two-thirds of the width direction of the corrugated sheet splicing large plate 56 as the third hoisting point; after selecting the three hoisting points, install the clamps for the corrugated sheet installation of the membrane tank. The clamping modules in the device are connected to the corrugated sections at the lifting points, and the corrugated sections are clamped and fixed by rotating the handle 13 to move the push-moving clamp 2. The lifting straps are connected to the shackles 15, and then the lifting straps are connected to the small crane 55 to lift the corrugated plate splicing large plate 56. When the corrugated plate splicing large plate 56 is lifted by the small crane 55, the corrugated plate splicing large plate 56 is parallel to the membrane tank wall. Three lifting points are selected for the corrugated plate splicing large plate 56, which improves the stability of the corrugated plate lifting. At the same time, the corrugated plate splicing large plate 56 is parallel to the membrane tank wall when lifted, which improves the convenience of the installation of the corrugated plate splicing large plate 56, improves the efficiency of the corrugated plate installation, and shortens the corrugated plate installation cycle.

[0049] In the fifth step above, when the corrugated plate splicing plate 56 is welded to the membrane tank wall, the amount of adhesion around the corrugated plate splicing plate 56 is not less than the total amount of adhesion between all individual corrugated plates in the corrugated plate splicing plate 56 and the membrane tank wall. This ensures the stability of the corrugated plate splicing plate 56 installation and improves the installation quality of the corrugated plate.
