Description

Technical Field

[0001] The utility model relates to the technical field of large-scale shell structure placement tooling, in particular to a large-scale shell structure placement rack. Background Art

[0002] The large shell structure placement rack is a device specially used to store and support large shell structures (such as large tanks, large pipelines, large reactor shells, etc.), thereby providing convenience for the transportation of the shells.

[0003] Taking the through-type tank as an example, after the through-type tank is placed on the placement rack, it needs to be fixed with a clamping plate. However, since the two ends of the through-type tank are designed with through holes, the curved structure is prone to deformation of the clamping part of the tank due to the concentration of pressure when subjected to the linear pressure of the clamping plate. Especially for thin-walled tanks, the risk of deformation is greater. If the clamping force is insufficient, the through-type tank is likely to shift in position during transportation, thereby reducing the stability of the placement of the through-type tank.

[0004] Therefore, a large shell structure placement rack is urgently needed to solve the above problems. Utility Model Content

[0023] It should be noted here that: through the setting of the fixing component, under the action of the protective component, the fixing points of the through-type tank body 101 are supported and protected, thereby dispersing the pressure generated by the external pressure fixation to a larger area, reducing pressure concentration, and increasing the support points inside the structure of the through-type tank body 101, so that when the shell is subjected to external pressure, there is a corresponding support structure inside to resist deformation, thereby ensuring the firm fixation of the through-type tank body 101 while reducing the risk of deformation of the through-type tank body 101 during the fixing process, thereby improving the stability and safety of the through-type tank body 101 placed on the placement rack.

[0024] See also Figure 2 and Figure 3 The protective assembly shown in the figure includes a circular plate 301 provided on one side of the mounting plate 201. The circular plate 301 is connected to the mounting plate 201 via a connecting assembly. The circular plate 301 is connected to four cylinders 302 via a rotating assembly. The sides of the four cylinders 302 that are away from each other are connected to an arc-shaped protective plate 303 via a second driving assembly.

[0025] It should be noted here that: through the setting of the protective component, support and protection of the fixed points are achieved, so that the pressure generated by the external pressure fixation is dispersed to a larger area, reducing pressure concentration, and increasing the support points inside the through-type tank body 101 structure, so that when the shell is subjected to external pressure, there is a corresponding support structure inside to resist deformation.

[0026] See also Figure 2 and Figure 3 The second driving assembly shown in the figure includes a driving tube 401 rotatably connected to the side of the cylinder 302 away from the circular plate 301. The driving tube 401 is threadedly connected to a threaded rod 402. One end of the threaded rod 402 is connected to the arc-shaped protective plate 303. The threaded rod 402 has a guide hole 403 arranged in a regular hexagon. The guide hole 403 is slidably connected to a guide rod 404. One end of the guide rod 404 is connected to the cylinder 302.

[0027] It should be noted here that the second driving assembly is provided to drive the arc-shaped protective plate 303 to move closer to or away from the inner wall of the through-type tank body 101 .

[0030] See also Figure 1 , the connecting assembly shown in the figure includes a T-shaped rod 601 slidably connected to the mounting plate 201, and an L-shaped rod 602 is slidably connected to one end of the T-shaped rod 601 close to the circular plate 301, and one end of the L-shaped rod 602 is connected to the circular plate 301;

[0031] It should be noted here that the arrangement of the connecting assembly facilitates the multi-directional movement of the circular plate 301 .

[0032] Working principle: When placing and fixing the through-type tank body 101, first, according to the length of the through-type tank body 101, the telescopic adjustment plate 103 is used to adjust the distance between the two bottom plates 102, and then the through-type tank body 101 is hoisted to the V-shaped plates 203 on the two bottom plates 102 using a hoisting device. After the through-type tank body 101 is hoisted to the two V-shaped plates 203 on the bottom plates 102, the first driving assembly is used to drive the V-shaped plates 203 on the mounting plate 201 to pre-tighten against the side walls of the through-type tank body 101;

[0033] After the two V-shaped plates 203 on the mounting plate 201 are pre-tightened against the side walls of the through-type tank body 101, the circular plate 301 is inserted into the interior of the through-type tank body 101 from the port thereof by using the connecting assembly, and then the arc-shaped protective plate 303 is aligned with the upper and lower V-shaped plates 203 and the side walls of the through-type tank body 101 at the positions where they abut against each other by using the rotating assembly, and the arc-shaped protective plate 303 is driven to abut against the inner wall of the through-type tank body 101 by rotating the driving tube 401 and utilizing the threaded engagement transmission effect of the driving tube 401 and the threaded rod 402 and the guiding effect of the guide hole 403 and the guide rod 404. After the four arc-shaped protective plates 303 are abutted against the inner wall of the through-type tank body 101, the first driving assembly is used again to The two V-shaped plates 203 on the mounting plate 201 are tightly against the side walls of the through-type tank body 101, thereby achieving the fixation of the through-type tank body 101 while utilizing the arc-shaped protective plate 303 to support and protect the fixing points, dispersing the pressure generated by the external pressing and fixing to a larger area, reducing pressure concentration, and increasing the support points inside the structure of the through-type tank body 101, so that when the shell is subjected to external pressing force, there is a corresponding support structure inside to resist deformation, thereby ensuring the firm fixation of the through-type tank body 101 while reducing the risk of deformation of the through-type tank body 101 during the fixing process, thereby improving the stability and safety of the through-type tank body 101 when placed on the placement rack.

[0034] Example 2

[0035] See also Figure 2 This embodiment further illustrates Example 1. The first driving assembly shown in the figure includes a mounting tube 701 fixedly connected to the bottom plate 102 near the mounting plate 201. The mounting tube 701 is threadedly connected to a screw rod 702. The mounting plate 201 is rotatably connected to a rotating rod 703. One end of the rotating rod 703 is connected to the screw rod 702, and the other end of the rotating rod 703 is fixedly connected to a rocker 704.

[0036] It should be noted here that: through the setting of the first drive component, during the rotation of the rocker 704, the mounting plate 201 is kept above the through-type tank body 101 by hand, and then the rocker 704 drives the screw rod 702 to rotate, and then under the threaded engagement transmission action of the screw rod 702 and the mounting tube 701, the mounting plate 201 is driven to move closer to or away from the through-type tank body 101, thereby achieving the fixing and release of the through-type tank body 101.
