Description

Technical Field

[0001] This utility model relates to the field of vertical pressure vessel technology, and specifically to a pressure testing fixture for a vertical pressure vessel. Background Technology

[0002] A pressure vessel is a sealed device that holds gas or liquid and withstands a certain pressure. The manufacturing process of a pressure vessel generally includes: raw material acceptance, scribing, cutting, rust removal, machining (including planing), rolling, assembly, welding (product welding test plates), non-destructive testing, drilling and scribing, final inspection, heat treatment, pressure testing, and corrosion prevention. Pressure vessels are divided into horizontal and vertical structures. Because pressure vessels typically have many auxiliary components, such as mounting positions for pressure gauges, thermometers, inlets, outlets, and lugs, horizontal testing methods are often used for vertical pressure vessels, especially for longer vertical structures. However, during testing, it has been found that vertical pressure vessels are difficult to place stably on a rolling device and are difficult to rotate for inspection.

[0003] In existing technologies, a pressure vessel testing fixture is disclosed. This fixture uses two V-shaped supports to position the pressure vessel, securing it in a location without any auxiliary parts on the cylinder, facilitating subsequent tilting tests. However, since pressure vessels are typically placed vertically in practical applications, testing a vertical pressure vessel using a horizontal testing method can lead to inaccurate structural inspections, affecting the normal operation of subsequent equipment. Other technologies employ a hoisting method, lifting the pressure vessel for inspection. However, pressure testing requires a relatively stable environment to avoid inaccurate data, and prolonged hoisting can damage the hoisted parts, affecting the normal installation of subsequent equipment. Still other technologies use support frames to support the pressure vessel for testing. However, current support frames are only suitable for equipment of a single diameter. For equipment of different diameters, it is necessary to remanufacture supports of the same size. Furthermore, the support frame cannot guarantee the verticality of the equipment, causing it to sway during testing, thus affecting the accuracy of subsequent test parameters. Utility Model Content

[0031] In the description of the present application, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to another element or there can be an intermediate element. In contrast, when the element is referred to as "directly" connected to another element, there is no intermediate element.

[0032] Please refer to Figures 1-10 The pressure test tool for the vertical pressure vessel of the preferred embodiment of the present application is used to support the vertical pressure vessel and facilitate subsequent pressure test. Specifically, the pressure test tool comprises a fixed support 10, a plurality of adjustable frame devices 20 and a plurality of rolling devices 30 mounted on the fixed support 10.

[0033] As Figures 1-2As shown, the fixed support 10 is used for overall support. The fixed support 10 includes legs 11, a base plate 12 and a top plate 13 disposed at opposite ends of the legs 11, and a support plate 14 disposed on the top plate 13. The legs 11 are inclined from bottom to top to form a stable V-shaped support structure. The V-shaped support structure forms a support for fixing a vertical pressure vessel. Reinforcing rods 15 are provided between adjacent legs 11 to further enhance the stability between the legs 11. In this embodiment, there are two reinforcing rods 15, which are arranged in a crisscross pattern. The base plate 12 and top plate 13 are designed to improve the stability of the support and increase the contact area between the legs 11 and the ground and support plate 14. In this embodiment, both the base plate 12 and top plate 13 are square, with the area of ​​the base plate 12 being larger than that of the top plate 13. The adjacent support plates 14 form a square structure, preferably a rectangular structure, which works in conjunction with the adjustable frame device 20 to support the pressure vessel. In one embodiment, as shown... Figure 8 As shown, the support plate 14 includes a first plate 140 and a second plate 141. The first plate 140 and the second plate 141 are fastened together and then fixed with bolts. This not only enhances the support strength with double-layer support, ensuring load-bearing capacity, but also provides installation space for installing the adjustable frame device 20 and the rolling device 30, and facilitates disassembly, replacement, and maintenance of internal parts. In this embodiment, the fixed brackets 10 are all made of channel steel, which can be stainless steel, carbon steel, or other materials.

[0034] Adjustable frame devices 20 are used to adjust the size of the frame to adapt it to the testing of pressure vessels of different sizes. Each adjustable frame device 20 is located at one of the four corners of the fixed support 10 to form a support frame with adjustable frame size. The support frame is used to support the lugs of the vertical pressure vessel. In this embodiment, as shown... Figure 3 and Figure 4As shown, the adjustable frame device 20 includes a fixed component 21, a spacing adjustment component 22 connected with the fixed component 21, and a support frame 23 connected with the spacing adjustment component 22. The fixed component 21 is bolted on the fixed support 10. The support frame 23 is used to abut with the rolling device 30 and the lug seat of the pressure container respectively. The support frame 23 is transversely arranged on the adjacent support plates 14 and is staggered with the adjacent support plates 14. The support frame 23 is movable on the support plates 14 to form an installation cavity for the pressure container to pass through. The installation cavity can be adjusted according to the size of different pressure containers. Meanwhile, the support frame 23 can abut with the lug seat of the pressure container to stably place the pressure container and ensure the verticality of the equipment, thereby further improving the test stability of the equipment. Since the pressure container is vertically placed, it can be directly tested in all aspects without rolling multiple angles, thereby facilitating the reduction of the test difficulty. Under the action of the fixed component 21, the spacing adjustment component 22 and other accessories, the moving direction of the support frame 23 can also be facilitated to avoid the deformation of the shape of the support frame formed, which affects the placement of the pressure container or uneven stress. The support frame 23 includes a first support rod 230 and a second support rod 231. A reinforcing rib 232 is arranged between the first support rod 230 and the second support rod 231 to facilitate the connection and disassembly of the support frame 23 with the pressure container. In this embodiment, the support frame 23 is made of channel steel and can be made of stainless steel, carbon steel or other materials.

[0035] In one embodiment, as shown in Figure 3 and Figure 4 The fixed component 21 includes a pad 210, a first rib plate 211 and a first rotating rib 212. The spacing adjustment component 22 includes a receiving taper rod 221, an extension taper rod 222 and a second rotating rib 220. The support frame 23 is provided with a second rib plate 233. The pad 210 is bolted on the support plate 14 of the fixed support 10. The first rib plate 211 and the first rotating rib 212 are movably connected. The second rotating rib 220 and the second rib plate 233 are movably connected. In the process of manual movement of the support frame 23, the moving direction of the support frame 23 can be ensured. The extension taper rod can be freely extended and retracted to ensure a certain range of movement to adapt to different diameter equipment. In this embodiment, a hinge device is arranged at the connection between the second rib plate 233 and the second rotating rib 220 to have a certain lateral movement range. When there is a certain error between the lug hole of the equipment and the support frame 23, the alignment can be adjusted and then fixed by bolts and nuts.

[0036] In another embodiment, the spacing adjustment component 22 further includes a driving mechanism (not shown in the figure). The driving mechanism is connected with the receiving taper rod to facilitate the use of automatic equipment instead of manual work to drive the movement of the support frame 23. The transmission shaft of the driving mechanism can be arranged in the first rotating rib 212. In this embodiment, the driving mechanism is a motor driving mechanism or a hydraulic transmission mechanism.

The spring 33 should be selected to have sufficient elastic force to support the sliding of the support plate 14 thereon.

[0038] In use, the size of the support frame of the adjustable frame device 20 is adjusted so that it can be put into the vertical pressure vessel, then the vertical pressure vessel is lifted by the lifting equipment and placed in the support frame, so that the lug seat of the vertical pressure vessel is located above the support frame, then the interval between the support frame 23 of the adjustable frame device 20 and the vertical pressure vessel is adjusted, the support frame 23 is slid to the position directly below the lug seat of the vertical pressure vessel by the action of the rolling device 30, then the vertical pressure vessel is lowered, so that the support frame 23 abuts against the lug seat of the vertical pressure vessel, and the support frame 23 and the lug seat of the vertical pressure vessel are fixed by the bolts, then the pressure test pipeline is connected, the pressure test equipment is connected, water or other test medium is introduced, the test is carried out according to the pressure test steps, after the test, the water or other test medium is emptied, the test equipment is disassembled, finally, the pressure vessel is lifted out by the lifting equipment, and the test is completed.
