Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of pressure vessels, and more particularly, to a pressure vessel shell stabilizing device. BACKGROUND

[0002] A pressure vessel refers to a closed equipment for containing gas or liquid and bearing certain pressure. According to the bearing pressure grade, it is divided into low-pressure vessels, medium-pressure vessels, high-pressure vessels, and super-high-pressure vessels. According to the contained medium, it is divided into non-flammable and non-toxic, flammable or toxic, and toxic categories. Pressure vessels can be reaction vessels (such as reactors, reaction kettles, etc.) for completing the physical and chemical reactions of media, heat exchange vessels (such as heat exchangers, coolers, etc.) for completing the heat exchange of media, separation vessels (such as separators, filters, etc.) for completing the mass exchange of media, gas purification, and solid-liquid-gas separation, and storage and transportation vessels (such as storage tanks, etc.) for containing liquid or gas materials, storing and transporting media, or balancing and buffering pressure. Pressure vessels are an important type of special equipment, and their safety and stability are of great significance to industrial production and people's life and property safety.

[0003] During welding and non-destructive testing, the pressure vessel shell (or tube box) needs to be continuously rotated. During rotation, especially when the diameter of the shell (or tube box) is large but the longitudinal dimension is relatively short, the shell (or tube box) often moves, causing the shell (or tube box) to deviate as a whole during welding and non-destructive testing, and even falling off the rotating platform, resulting in safety accidents. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present disclosure provides a pressure vessel shell stabilizing device which is simple in structure, easy to disassemble and assemble, has a wide range of applications, and can effectively prevent the pressure vessel shell (or tube box) from moving during welding and non-destructive testing, thereby avoiding the pressure vessel shell (or tube box) from falling off the rotating platform and improving safety and stability.

[0005] Specifically, the present disclosure provides a pressure vessel shell stabilizing device, which comprises a support base, a central shaft, a stabilizing member, and a fixing assembly. One end of the central shaft is fixed to the support base, the stabilizing member is fixed to the other end of the central shaft away from the support base, and the fixing assembly is configured to fix the central shaft to a rotating platform for placing a pressure vessel shell.

[0006] Optionally, the fixing assembly comprises an upper fixing plate and a lower fixing plate capable of clamping the rotating platform, and the upper fixing plate is fixed to the central shaft through a connecting rod.

[0007] Optionally, the upper fixing plate and the lower fixing plate are fixed together by screw connection.

[0008] Optionally, the connecting rod is a telescopic rod.

[0009] Optionally, the central axis is a telescopic axis.

[0010] Optionally, the stabilizing element is made of rubber.

[0011] Optionally, the stabilizing element is a rubber rod.

[0012] Optionally, the support base, the central shaft, the connecting rod, the upper fixing plate, and the lower fixing plate are all made of Q345R steel.

[0013] Compared with the prior art, the pressure vessel cylinder stabilization device provided in this disclosure has at least the following beneficial effects:

[0014] The pressure vessel shell stabilizing device disclosed herein is equipped with stabilizing components. In use, the pressure vessel shell stabilizing device is installed on the side of the inlet pipe and the side away from the inlet pipe of the pressure vessel shell, respectively. One stabilizing component abuts against the inlet pipe of the pressure vessel shell, and the other stabilizing component abuts against the side of the pressure vessel shell away from the inlet pipe. Then, the stabilizing components are fixed to the turntable by the fixing components. In this way, the pressure vessel shell can be effectively prevented from moving and falling off the turntable. Thus, the pressure vessel shell can be safely protected during welding and non-destructive testing, which is of great significance for the safe production of equipment. Attached Figure Description

Figure 1 and Figure 2 As shown, the pressure vessel shell stabilizing device includes a support base 1, a central shaft 2, a stabilizing member 3, and a fixing assembly.

The fixing assembly is configured to fix the central shaft 2 to a turntable 7 for placing the pressure vessel shell 8. Thus, the stabilizing member 3 is fixed to the turntable 7 via the central shaft 2. In use, the pressure vessel shell stabilizing device is installed on one side of the pressure vessel shell 8 near the nozzle 9 and on the other side away from the nozzle 9, so that one stabilizing member 3 abuts against the nozzle 9 of the pressure vessel shell, and the other stabilizing member 3 abuts against the other side of the pressure vessel shell away from the nozzle 9. Then, the fixing assembly fixes the stabilizing member 3 to the base of the turntable 7.

Specifically, the upper fixing plate 5 is provided with a plurality of upper bolt holes 51, and the lower fixing plate 6 is provided with a plurality of lower bolt holes 61. In use, the base of the turntable 7 is clamped between the upper fixing plate 5 and the lower fixing plate 6, and then the upper fixing plate 5 and the lower fixing plate 6 are fixed together by bolts and nuts.

[0024] In a preferred embodiment of this disclosure, the connecting rod 4 is a telescopic rod and the central shaft 2 is a telescopic shaft, thus making it applicable to pressure vessel cylinders of different diameters and longitudinal dimensions, with a wide range of applications.

[0025] In a preferred embodiment of this disclosure, the stabilizing member 3 is a rubber rod, which can prevent damage to the surface of the pressure vessel cylinder 8.

[0026] In a preferred embodiment of this disclosure, the support base 1, the central shaft 2, the connecting rod 4, the upper fixing plate 5, and the lower fixing plate 6 are all made of Q345R steel, whose low alloy and high strength characteristics fully meet the requirements for long-term use.
