Technical Field
[0001] The utility model generally relates to the technical field of lifting ears for lifting, and more specifically, to a lifting ear structure of a thin-wall container and a thin-wall container comprising the lifting ear structure. Background Art
[0002] Among pressure vessels, atmospheric pressure vessels with large diameters are often encountered. Due to their thin wall thickness, ordinary lifting lugs are often easy to deform the shell of the container during lifting, resulting in difficulty in lifting. In order to solve the shell deformation problem, additional supports are often installed inside the shell of the container, but this method is time-consuming and labor-intensive, and extremely inconvenient. Utility Model Content
[0003] In view of this, the purpose of the utility model is to improve the lifting ear structure to facilitate lifting and better avoid deformation of the container shell, thereby solving the problem of difficulty in lifting thin-walled containers.
[0004] In order to solve the above technical problems or achieve the above purposes, the utility model adopts the following technical solutions:
[0005] According to one aspect of the utility model, there is provided an ear structure for a thin-walled container, comprising: an ear plate, on which a hole is provided, and a first recess is provided below one side of the ear plate; a bracket assembly, which is fixedly connected to the bottom of the ear plate at an angle relative to the vertical center line of the ear plate; a padding plate, which is fixedly connected to the first recess, and one side of the padding plate is fixedly connected to the bracket assembly, and the other side of the padding plate is fixedly connected to the shell of the thin-walled container together with the ear plate.
[0006] Optionally, the bracket assembly is square, and includes a cover plate, a bottom plate, and two rib plates fixedly connected between the cover plate and the bottom plate.
[0007] Optionally, a second recess is provided above one side of the ear plate, and the second recess is fixedly connected to an angle steel of a shell surrounding the thin-walled container.
[0008] Optionally, the bracket assembly is angled at 30° or 45° relative to the vertical centerline of the ear plate.
[0009] Optionally, the hole is located in the middle of the ear plate, and the number of the hole is one.
[0010] Optionally, the pad is a square pad.
[0011] Optionally, the thin-walled container comprises an atmospheric pressure container.
[0012] Optionally, the fixed connections are all fixed by welding.
[0013] Optionally, the ear plate, the pad plate, the cover plate, the bottom plate and the rib plate are all made of Q345R steel plate.
[0014] In addition, according to another aspect of the utility model, a thin-walled container is provided, and the thin-walled container includes the ear structure of the thin-walled container as described above.
[0015] By adopting the above technical solution, the utility model has the following advantages compared with the prior art:
[0016] When hoisting a large-diameter thin-walled container, the utility model avoids the situation that the shell is easily deformed due to the small force area of the conventional lifting lugs and the relatively concentrated force on the shell. The utility model adds a pad and a bracket assembly under the conventional lifting lugs, which can increase the force area during hoisting. The lifting lugs themselves also have a better force angle and method, thereby better avoiding the deformation of the shell of the container. At the same time, the utility model does not need to install a support inside the container during hoisting, which can save manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 The left side shown in the figure) is welded and fixed to the bracket assembly 9, and the other side of the pad 4 (as shown in the figure) is welded and fixed to the bracket assembly 9. Figure 1 The right side shown in the figure) is welded and fixed together with the ear plate 5 to the shell of the thin-walled container (not shown in the figure).
[0023] Through the above structure of the utility model, the utility model can better avoid the shell deformation of the container during hoisting. At the same time, the utility model does not need to install support inside the container during hoisting, which can save manpower and material resources.
[0024] In a preferred embodiment of the present invention, Figure 2 As shown, the bracket assembly 9 can exist in the form of a square structure, and the bracket assembly 9 includes a cover plate 3, a bottom plate 1, and two vertical rib plates 2 welded and fixed between the cover plate 3 and the bottom plate 1. Through the bracket assembly 9 of this structure, the bracket assembly 9 can be stressed together with the lifting ear plate 5 during hoisting, and is welded and fixed with the pad 4 at the same time, so that there is a larger stress-bearing area during hoisting, thereby avoiding deformation of the shell of the container.
[0025] In a preferred embodiment of the present invention, in the bracket assembly 9, only one rib plate 2 may be welded and fixed between the cover plate 3 and the bottom plate 1, or more than two rib plates 2 may be welded and fixed.
[0026] In a preferred embodiment of the present invention, the bracket assembly 9 may also exist in the form of other shapes and structures. It is only necessary to ensure that the bracket assembly 9 can be subjected to force together with the ear plate 5 during hoisting, and can be fixedly connected to the pad 4 to increase the force-bearing area during hoisting.
[0027] In a preferred embodiment of the present invention, Figure 1 As shown, when the backing plate 4 and the ear plate 5 are welded and fixed to the shell of the thin-walled container, one side of the ear plate 5 (such as Figure 1 The second recess 8 arranged above the right side of the thin-walled container (as shown) will be fixedly connected to the angle steel (not shown in the figure) of the shell surrounding the thin-walled container.
[0028] In a preferred embodiment of the present invention, Figure 1As shown, the hole 6 on the eye plate 5 of the utility model is located in the middle of the eye plate 5, and the number of the hole 6 is 1. In this way, the vertical center line of the eye plate 5 coincides with the vertical center line of the hole 6, and the bracket assembly 9 is welded and fixed at an angle α relative to the vertical center line of the eye plate 5. In essence, the bracket assembly 9 is welded and fixed at an angle α relative to the vertical center line of the hole 6, which helps to better position and weld the bracket assembly 9.
[0029] In a preferred embodiment of the present invention, Figure 1 As shown, the angle α of the bracket assembly 9 relative to the vertical center line of the ear plate 5 or the hole 6 can be 30° or 45°.
[0030] In a preferred embodiment of the present invention, α is preferably 30°. The bracket assembly 9 fixed at this angle is structurally strong and has better stress resistance.
[0031] In a preferred embodiment of the present invention, Figure 2 As shown, the pad 4 in the present invention is preferably a square pad.
[0032] In a preferred embodiment of the present invention, the thin-walled container comprises a normal pressure container. Alternatively, the thin-walled container may also be other types of containers.

[0034] In addition, the utility model can also provide a thin-walled container, which includes the ear structure of the thin-walled container as described above.
[0035] When the above-mentioned lifting lug structure is used, the bracket assembly 9 (bottom plate 1, rib plate 2 and cover plate 3), pad plate 4 and lifting lug plate 5 are welded together according to the above-mentioned structural design, and then firmly welded to the shell of the thin-walled container. When lifting is required, the steel wire rope is passed through the hole 6 on the lifting lug plate 5 for lifting. During the lifting process, there is no need to install additional support inside the shell of the container, and there will be no problem of deformation of the container shell.
[0036] Therefore, the utility model adds a pad and a bracket assembly under the conventional lifting lug, which can increase the force-bearing area during lifting, and the lifting lug itself has a better force-bearing angle and mode, which can better avoid the deformation of the container shell. At the same time, when using the above structure of the utility model for lifting, there is no need to add support inside the container, which can save manpower and material resources.
