Description

Technical Field

[0001] The utility model relates to the technical field of container movement and replacement, in particular to a tank body replacement device. Background Art

[0002] During the in-service inspection of some large tank structures, it was found that there were defects exceeding the standard on the ring weld between the container head and the cylinder, which needed to be processed. At the same time, it was necessary to check whether the inner wall pressure of the tank body as a pressure vessel exceeded the standard. If there was a defect, the defect was eliminated after repair and water pressure test, but ultrasonic testing found that the defects in other areas of the weld did not exceed the standard and expanded. However, when the tank body cannot achieve defect repair, the corresponding tank body needs to be replaced.

[0003] For example, the replacement of hydrogen tanks in hydrogen production stations is carried out by dismantling the ceiling and lifting. During the actual work, the method of dismantling the ceiling and lifting requires the construction of an 8-meter-high scaffolding to lift the tank for replacement. However, the method of dismantling the ceiling and lifting has the risk of falling from a height, resulting in poor safety of tank replacement.

[0004] Therefore, how to improve the safety of tank replacement is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0042] The core of the utility model is to provide a tank body replacement device to improve the safety of tank body replacement.

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0044] Please refer to Figures 1 to 7 .

[0045] In a specific embodiment, the tank replacement device provided by the specific embodiment of the utility model includes a first support module 5 and a second support module 2, the first support module 5 includes a first support 501 and a lifting device 502 installed at the bottom of the first support 501 and used to lift the tank 101, and the upper surface of the first support 501 is a first support surface that fits the bottom of the tank 101. The lifting device 502 can be a hydraulic cylinder, a cylinder or a jack. Preferably, at least two lifting devices 502 are provided under each first support 501. Specifically, the lifting devices 502 installed on each first support are arranged in sequence along a direction perpendicular to the axis of the tank 101.

[0046] The second support module 2 includes a second support 201 and a walking device 202 installed at the bottom of the second support 201 and used to drive the tank body 101 to move. The upper surface of the second support 201 is a second supporting surface that fits the bottom of the tank body 101. Specifically, the walking device 202 can be an electric wheel, for example, the walking device 202 is composed of a plurality of electric wheels arranged in an array.

[0047] When the tank 101 needs to be replaced, the first support module 5 is first placed under the tank 101, and the top of the lifting device 502 is raised to drive the first support 501 to rise, and finally the tank 101 is lifted up. Then the second support module 2 is placed under the tank 101, and the lifting device 502 is lowered until the second support 201 supports the tank 101. The tank 101 and the second support module 2 move to the preset position driven by the walking device, and the new tank 101 moves to the initial position in the same way.

[0048] In order to improve the support stability, when the tank body 101 is lifted up, at least two groups of first support modules 5 are arranged along the axial direction of the tank body 101 .

[0049] It can be seen from the above description that in the tank body replacement device provided in the specific embodiment of the present application, the tank body 101 is lifted up by the first support module 5, and the tank body 101 is driven to move by the second support module 2. The tank body 101 moves and is replaced under the action of the first support module 5 and the second support module 2. There is no need to lift the tank body 101 for transportation. The tank body replacement device provided in the present application improves the safety of replacing the tank body 101.

[0050] In a specific embodiment, the tank replacement device further includes a bottom plate 3 and a moving device 4. The bottom plate 3 is used to support the tank 101, the first support module 5 and the second support module 2. Specifically, the first support module 5 and the second support module 2 are placed on the bottom plate 3. In order to improve the support stability, preferably, the bottom plate 3 is a steel plate. Of course, in specific use, the bottom plate 3 can be an aluminum plate, a plastic plate, etc. The bottom plate 3 can specifically be a steel plate with a thickness of 18mm-22mm, for example, the bottom plate 3 is a steel plate with a thickness of 20mm.

[0051] When the hydrogen tank 1 is moved, the bottom plate 3 is laid along the shipping path of the tank body 101. For example, if the overall transportation length of the tank body 101 is 22 meters, the bottom plate 3 is laid in a width of three meters. The adjacent steel plates are preferably connected by spot welding, and the bottom of the bottom plate 3 is leveled with fine sand. Finally, all the steel plates are connected together to form the bottom plate 3.

[0052] Before the hydrogen tank 1 is moved as a whole, it is necessary to ensure that there is at least 18m of space in the moving direction in front of the hydrogen tank 1 for the hydrogen tank 1 to move. The support seat 102 on the tank body 101 of the hydrogen tank 1 is separated from the welded part of the cement support foot to ensure that the hydrogen tank 1 can be lifted as a whole by external force.

[0053] The moving device 4 is detachably connected to the bottom plate 3 to push the tank 101 to move relative to the bottom plate 3. Since the tank 101 is usually large in size, in order to make the support device stably drive the tank 101 to move, the bottom plate 3 is arranged under the moving device 4, and preferably, the bottom plate 3 is a flat plate structure.

[0054] In a specific embodiment, the moving device 4 includes a fixing member 401 and a hand chain hoist 402, and the fixing member 401 is fixed to the upper surface of the bottom plate 3. Figure 2 As shown, the hand chain hoist 402 connects the fixing member 401 and the tank body 101 to pull the tank body 101 to move relative to the bottom plate 3. Specifically, the fixing member 401 can be a sheet metal structure, and the fixing members 401 are provided on both the front and rear sides of the moving direction of the tank body 101, and one or two fixing members 401 can be provided on each side. When in use, the tank body 101 is driven to move by the hand chain hoist 402.

[0055] Considering that the positions of the first support module 5 and the second support module 2 need to be changed during the movement of the tank 101, preferably, the first support module 5 and the second support module 2 can be detachably mounted on the upper surface of the bottom plate 3. Specifically, the first support module 5 and the second support module 2 are arranged in contact with the upper surface of the bottom plate 3.

[0056] As shown in Figure 4, in a specific embodiment, the first support 501 includes an upper support plate 50101, an intermediate support plate 50104, a lower support plate 50103 and a vertical plate 50102. The upper surface of the upper support plate 50101 is an arc surface that fits the surface of the tank body 101. Specifically, when the tank body 101 is a cylindrical structure, the upper surface of the upper support plate 50101 is an arc surface. The intermediate support plate 50104 is located between the upper support plate 50101 and the lower support plate 50103, and is isolated. Specifically, the distance between the intermediate support plate 50104 and the upper support plate 50101 and the lower support plate 50103 is determined according to needs, and this application does not make specific restrictions. The upper support plate 50101, the intermediate support plate 50104 and the lower support plate 50103 are connected to the vertical plate 50102 in sequence from top to bottom.

[0057] In order to improve the support stability, preferably, there are multiple vertical plates 50102, and the multiple vertical plates 50102 are arranged in sequence along the horizontal direction, and two adjacent vertical plates 50102 are isolated. Specifically, the distance between two adjacent vertical plates 50102 is determined according to actual needs. The vertical plates 50102 can be flat plates or special-shaped plates with reinforcing ribs.

[0058] like Figure 5 As shown, the first support 501 includes an upper support plate 50101, a lower support plate 50103 and a vertical plate 50102, which is equivalent to Figure 4 The implementation shown reduces the provision of the intermediate support plate 50104 .

[0059] In order to improve the support stability, preferably, the first support 501 and the second support 201 are metal support seats.

[0060] Preferably, the first support 501 and the second support 201 may be supports of the same structure. With such an arrangement, when assembling the first support module 5 and the second support module 2, the staff does not need to distinguish which is the first support 501 and which is the second support 201.

[0061] like Figure 6 and Figure 7 As shown, in a specific embodiment, the walking device 202 includes a tank trolley, and the tank trolley includes a vehicle body 20201 and rollers 20202 installed in an array on the vehicle body 20201. Specifically, the number of rollers 20202 installed on each vehicle body 20201 is determined according to needs, and at least two tank trolleys are preferably arranged on each second support 201.

[0062] Preferably, the upper surfaces of the first support 501 and the second support 201 are provided with anti-skid patterns to improve the anti-skid effect of the tank body 101. Specifically, an anti-slip structure can be provided along the front and rear directions of the tank body 101. Figure 2 As shown, the hand winch 402 is used to pull the tank body 101 to the left. In order to reduce sliding, preferably, the first support 501 is welded to the support seat 102 on the tank body 101 to prevent sliding during pulling.

[0063] For ease of understanding, the following describes the replacement of the hydrogen production tank 1 in conjunction with a specific tank replacement device:

[0064] First, prepare two first support modules 5 and two second support modules 2, and then place the two first support modules 5 on both sides of the lower part of the tank body 101. Each first support module 5 includes two hydraulic jacks, and the hydrogen tank 1 is lifted up as a whole by the jacks acting on the first support 501. Then place the two second support modules 2 on both sides of the lower part of the tank body 101, set two tank trolleys under each second support 201, slowly drop the jacks, and after the hydrogen tank 1 is stabilized on the second support 201, remove the jacks and the first support 501, set the fixings 401 on the steel plates on both sides as anchor points, and use the hand chain hoist 402 to pull and realize the translation of the hydrogen production tank 1. Specifically, pull the hand chain hoist 402 installed on the rear side of the hydrogen tank 1 to prevent the hydrogen tank 1 from sliding down quickly without safety protection when going downhill. Slowly pull the hand chain hoist 402 to pull out the hydrogen tank 1 as a whole. Since the tank trolley and the bottom plate 3 are rolling friction, if the hydrogen tank 1 deviates, stop pulling and adjust it.

[0065] After the hydrogen tank 1 moves a certain distance, the hand chain hoist 402 also moves a certain distance to remove the second support module 2 at the rear end. Specifically, the tank body 101 can be lifted up by the first support module 5 for removal. Then it is installed at the front end of the moving end of the hydrogen tank 1, and the tank body 101 is continued to be pushed. This operation is repeated until the entire lifting point of the hydrogen tank 1 is moved out of the ceiling.

[0066] Specifically, after the hydrogen tank 1 is shipped to the designated location, the steel platform above the hydrogen tank 1 is first removed, and the large-tonnage crane of the hydrogen station is used to lift the hydrogen tank 1 to the gravel ground. After the new hydrogen tank 1 arrives at the site, the steel platform is installed above the new hydrogen tank 1, and the crane is used to lift it to the lifting position of the old hydrogen tank 1, and then the new hydrogen tank 1 is moved to the previous installation position of the old hydrogen tank 1, that is, the initial position, through the first support module 5 and the second support module 2.

[0067] When replacing the hydrogen tank 1, the base and the attached pipelines of the old hydrogen tank 1 are cut on site. Specifically, the support base 102 of the hydrogen tank is separated from the welded part of the cement support foot to ensure that the hydrogen tank can be lifted as a whole by external force. The tank body 101 and the second support module 2 are supported by the tank trolley through the first support module 5 and the second support module 2. The overall structure is simple, easy to use, and easy to be widely promoted and used.

[0068] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
