Description

Technical Field

[0001] The utility model generally relates to the field of pressure vessels, and in particular to a pressure vessel hoisting device. Background Art

[0002] Generally, in the manufacturing plants that produce pressure vessels, especially non-standard pressure vessels, the pressure vessels have different sizes and structures, including tower type, heat exchanger, skirt tank, support tank, etc.

[0003] When lifting the pressure vessel equipment after production is completed, wire ropes are mostly used for lifting. The cylinder of the pressure vessel equipment is in direct contact with the wire rope and subjected to force. The paint surface of the equipment is squeezed and cracked or corrugated. To repair the paint surface, the damaged paint surface needs to be polished and removed and then repainted. The color and performance of the repaired paint surface are greatly reduced. Some large-diameter thin-walled equipment may be deformed due to the influence of its own weight during the lifting process, affecting the performance of the equipment.

[0004] In order to better solve the above problems, this device for fixed lifting and transportation of pressure vessels is designed and manufactured to lift the equipment onto a transport vehicle. It has low cost, simple operation and wide application range. Utility Model Content

The arc bracket assembly comprises an arc plate, and the two ends of the connecting rope are fixedly connected to the two ends of the arc plate, and the pressure vessel is arranged in the arc plate.

[0007] In some preferred embodiments, the number of the lifting ears is eight and they are arranged in pairs.

[0008] In some preferred embodiments, the crossbeam is an I-beam.

[0017] like Figure 1 As shown, the utility model provides a pressure vessel lifting device, including a lifting steel beam assembly and an arc bracket assembly, the lifting steel beam assembly includes a cross beam 6, the upper and lower surfaces of the cross beam 6 are fixedly connected with lifting ears 5, the surface of the lifting ear 5 is provided with a U-shaped ring 8, a connecting rope 7 is passed through the U-shaped ring 8, one end of the connecting rope 7 is connected to the hook of the crane, and the other end of the connecting rope 7 is fixedly connected to the arc bracket assembly, the arc bracket assembly includes an arc plate 1, both ends of the connecting rope 7 are fixedly connected to both ends of the arc plate 1, a pressure vessel is arranged in the arc plate 1, the cross beam 6 is an "I" beam, a flexible rubber pad is arranged on the contact surface between the arc plate 1 and the pressure vessel, the connecting rope 7 is a steel wire rope, and a rib plate 2 is fixedly connected to the surface of the arc plate 1.

[0018] In a preferred embodiment, Figure 1 and Figure 2As shown, first place the arc plate 1, rib plate 2, connection plate 4, and arc support plate welded together under the container equipment, and then place a flexible rubber pad at the contact surface between the arc support plate and the container equipment to avoid crushing the outer wall of the pressure vessel. Place the object to be carried (such as skirt-type pressure vessel, tower container, ear-type pressure vessel, special placement pressure vessel, round cylinder, etc.) on the flexible rubber pad on the surface of the arc plate, and then assemble the lifting steel beam assembly composed of "I" steel, lifting lug 5, connecting rope 7, and U-shaped ring 8, and insert the connecting rope 7 into the U-shaped ring 8, and then use a crane to lift it. By combining the arc plate 1 with the "I" beam, it can effectively prevent the equipment cylinder from directly contacting the steel wire rope and being subjected to force, so that the paint surface of the equipment is squeezed to produce cracks or corrugated damage, and it can also prevent large-diameter thin-walled equipment from being deformed during the lifting process, affecting the performance of the equipment in subsequent use.

[0019] In another preferred embodiment, Figure 1 As shown, the surface of the arc plate 1 is fixedly connected with a rib plate 2, which can strengthen the pressure that the arc plate 1 can bear and avoid deformation. The U-shaped ring 8 can ensure that the connecting rope 7 can always be in the middle position of the U-shaped ring 8 when the connecting rope 7 is under force, and will not shake, thereby improving the stability during lifting.

[0020] In another preferred embodiment, Figure 1 and Figure 3 As shown, there are eight lifting lugs 5, and they are arranged in pairs. The correspondingly arranged lifting lugs 5 can make the force of the "I" beam more uniform and avoid tilting. The cross-designed connecting rope 7 can make it easier to fix the hook so that the force of the hook is more concentrated, which is convenient for lifting the "I" steel.

[0021] In another preferred embodiment, Figure 1 and Figure 4 As shown, the arc plate 1 and the rib plate 2 are divided into a left plate and a right plate, and the surfaces of the ends of the rib plates 2 that are close to each other are fixedly connected with a connecting plate 4, and the connecting plates 4 are fixedly connected by fasteners 3. The initial welding shape of the arc plate 1, the rib plate 2 and the connecting plate 4 is an arc shape, and they are fixedly connected by welding. The initial state of the arc plate 1, the rib plate 2 and the connecting plate 4 is that they are divided into two halves, the left plate and the right plate. After being welded separately, the two groups of arc plates 1, rib plates 2 and connecting plates 4 are integrated with fasteners 3. After the container equipment is hoisted onto the transport vehicle, the fasteners 3 on the surfaces of the two connecting plates 4 at the bottom are removed to separate them into two halves and detach them from the container equipment. The two-flap arc plate 1, the rib plate 2 and the connecting plate 4 can improve the disassembly efficiency, thereby improving the hoisting efficiency.

When the relative positions change, the original "left end" can be considered as the "right end", and the original "right end" can be considered as the "left end".
