Description

Technical Field

[0001] The present application relates to the technical field of liquefied storage tank manufacturing, and in particular to a shielding layer leveling device. Background Art

[0002] LNG liquefied storage tanks are key equipment for liquefied natural gas transportation. Their thermal insulation and pressure resistance directly affect transportation safety. To achieve good thermal insulation performance, a shielding layer is required on the inner wall of the tank to improve the storage safety of the LNG inside the tank.

[0003] Reference Figure 1 In the prior art, the shielding layer is formed by splicing together multiple unit modules 7. The surfaces of the unit modules 7 are interlaced horizontally and vertically, and the intersections form rosettes 71. After the multiple unit modules 7 are laid out on the inner wall of the storage tank, the welds between adjacent unit modules 7 are welded using a welding torch to connect the multiple unit modules 7 into a whole, forming a shielding layer covering the inner wall of the storage tank.

[0004] However, for large storage tanks, the shielding layer has a large number of unit modules, which are mainly laid manually. It is difficult to ensure high consistency between the unit modules by manual labor. This not only leads to low overall flatness of the shielding layer, but also seriously affects the quality of subsequent welding operations, thereby reducing the laying accuracy and reliability of the entire shielding layer. Therefore, there is an urgent need for an auxiliary device that can level the shielding layer to improve the laying quality of the shielding layer. Summary of the Invention

[0005] In order to improve the flatness of the shielding layer, the present application provides a shielding layer leveling device.

[0006] The shielding layer leveling device provided in this application adopts the following technical solution:

There are multiple connecting seats, and the multiple connecting seats are respectively arranged on different unit modules. There are multiple horizontal bars and vertical bars. The horizontal bars are used to connect multiple connecting seats arranged horizontally in series, and the vertical bars are used to connect multiple connecting seats arranged vertically in series; the connecting seats are respectively provided with a first connecting component and a second connecting component. The connecting seat can be detachably installed at the flower knot of the unit module through the first connecting component, and the horizontal bars and vertical bars can be detachably installed on the connecting seat through the second connecting component.

[0008] By adopting the above-mentioned technical solution, after multiple unit modules are laid out in sequence on the inner wall of the storage tank to form a surface, the connecting seat is arranged at the knot of the unit module through the first connecting component. After multiple connecting seats are laid out in sequence, the horizontal bars and vertical bars are laid out, and the horizontal bars and vertical bars are installed on the connecting seat through the second connecting component, so that the horizontal bars can connect in series the multiple connecting seats arranged horizontally, thereby improving the flatness between the multiple unit modules arranged horizontally, and the vertical bars can connect in series the multiple connecting seats arranged vertically, thereby improving the flatness between the multiple unit modules arranged vertically, greatly improving the flatness of the shielding layer, and facilitating subsequent welding operations, thereby improving the laying quality of the shielding layer.

[0009] Optionally, the first connecting assembly includes a fixed clamp block, a movable clamp block and a driving member, the fixed clamp block is fixedly connected to the bottom wall of the connecting seat, the movable clamp block is slidably installed on the bottom wall of the connecting seat and can move close to or away from the fixed clamp block, and a clamping area for the knot of the unit module to be embedded is formed between the fixed clamp block and the movable clamp block; the driving member is arranged on the connecting seat to push the movable clamp block to slide.

[0010] By adopting the above-mentioned technical solution, when installing the connecting seat, the connecting seat is placed on the unit module so that the knot of the unit module is embedded in the clamping area, and then the driving member drives the movable clamping block to move toward the side close to the fixed clamping block, so that the fixed clamping block and the movable clamping block are jointly clamped on the knot of the unit module, thereby realizing the installation of the connecting seat at the knot of the unit module and improving the convenience of disassembly and assembly of the connecting seat.

[0011] Optionally, the surface of the unit module is protrudingly provided with horizontal ribs and vertical ribs, which are cross-arranged to form the flower knot; the bottom wall of the fixed clamp block and the bottom wall of the movable clamp block are both provided with positioning arc grooves for the vertical ribs to be embedded, and the side walls of the fixed clamp block and the movable clamp block that are close to each other are both provided with positioning embedded blocks, and the two opposite sides of the horizontal ribs have positioning embedded grooves for the positioning embedded blocks to be matched and embedded.

[0012] By adopting the above technical solution, the setting of the positioning arc groove can position the connection seat and improve the installation accuracy; the setting of the positioning block reduces the possibility of the connection seat rotating freely around the vertical rib, thereby reducing the possibility of the surface of the connection seat tilting.

[0013] Optionally, the second connecting component includes a connecting column and a leveling sleeve, the connecting column is arranged on the upper surface of the connecting seat, and the top wall of the connecting column is respectively provided with a horizontal groove for the horizontal bar to be embedded and a vertical groove for the vertical bar to be embedded, and the horizontal groove and the vertical groove are interconnected and cross-arranged; the leveling sleeve is arranged on the outer surface of one end of the connecting column away from the connecting seat and is threadedly connected to the connecting column.

[0014] By adopting the above-mentioned technical solution, when installing the horizontal and vertical bars, the horizontal bars are embedded in the horizontal grooves, the vertical bars are embedded in the vertical grooves, and then the leveling sleeve is screwed into the outer surface of the end of the connecting column away from the connecting seat. The leveling sleeve can connect the connecting column, horizontal bars and vertical bars as a whole, thereby improving the installation convenience of the horizontal and vertical bars; by rotating the leveling sleeves of multiple connecting seats, the flatness between multiple unit modules can be adjusted.

[0016] By adopting the above-mentioned technical solution, the setting of the chamfered surface makes it easier for the horizontal bars to be embedded in the horizontal grooves and the vertical bars to be embedded in the vertical grooves; the setting of the abutment plate and the compression spring makes it possible for the compression spring to contract and produce elastic force after the leveling sleeve is tightened, and this elastic force reacts on the leveling sleeve, thereby improving the stability of the threaded connection between the leveling sleeve and the connecting column and reducing the possibility of free rotation of the leveling sleeve.

[0017] Optionally, both the horizontal bars and the vertical bars include a plurality of unit segments connected end to end, and a butt joint is provided between two adjacent unit segments, and the two adjacent unit segments are connected to each other through the butt joint.

The movable seat is slidably installed with a flattening plate for flattening the corners of the unit module; a flip telescopic rod is provided between the movable seat and the four adjacent connecting seats, and the movable seat is slidably installed in the flattening area through multiple flip telescopic rods.

[0019] By adopting the above-mentioned technical solution, there is a certain probability that the corners of the unit modules will warp and deform during the manufacturing, transportation and laying processes. When the corners of the unit modules warp and deform, a movable seat is installed between the four adjacent connecting seats according to the warping position, and the warping position is flattened by the pressing plate of the movable seat to facilitate subsequent welding operations between the corners of adjacent unit modules; by setting a flip telescopic rod, the movable seat is slidably installed in the flattening area, so that the position of the movable seat can be appropriately adjusted according to the warping position of the unit module, thereby improving the flexibility of the overall structure.

[0020] Optionally, the movable seat is slidably installed with a lifting rod, the lower end of the lifting rod is connected to the pressure plate, and the pressure plate is slidably installed on the movable seat through the lifting rod; a return spring is provided between the pressure plate and the movable seat, and the return spring normally forces the pressure plate to separate from the surface of the unit module; the upper end of the lifting rod is rotatably connected to a force pressure plate, and the force pressure plate is connected to a limiting block. The outer peripheral wall of the movable seat is provided with a sliding groove for the limiting block to slide, and the outer peripheral wall of the movable seat is provided with a limiting groove connected to the sliding groove. When the force pressure plate is driven to rotate and forces the limiting block to move into the limiting groove, the pressure plate is pressed against the surface of the unit module.

[0021] By adopting the above-mentioned technical solution, after the movable seat is installed in the flattening area, a certain pressure is applied to the force-applying pressure plate, driving the pressure plate to press against the warped parts at the corners of the unit module to restore the warped parts of the unit module; after the pressure plate presses against the warped parts of the unit module, the force-applying pressure plate is rotated to drive the limit block to rotate the limit slot, so that the pressure plate remains pressed against the unit module, thereby improving the operational convenience of restoring the warped parts of the unit module.

[0022] Optionally, the flip telescopic rod includes a first connecting rod and a second connecting rod, one end of the first connecting rod is hinged to the connecting seat, and the other end is provided with a plug-in slot, and one end of the second connecting rod is hinged to the movable seat, and the other end is slidably inserted into the plug-in slot.

[0023] Optionally, a rotating rod is provided on the surface of the connecting seat, and a rotating groove for inserting the rotating rod is opened at the end of the first connecting rod away from the second connecting rod, and the first connecting rod is hinged to the connecting seat through the rotating rod; the rotating rod is provided with a mounting piece, and the first connecting rod is detachably mounted on the rotating rod through the mounting piece.

[0024] By adopting the above-mentioned technical solution, the first connecting rod is detachably mounted on the rotating rod of the connecting seat through the docking assembly, so that the movable seat can be detachably mounted in the flattening area. When the raised part of the unit module is flattened by the flattening plate and fixed by spot welding, the limiting effect of the first connecting rod can be released by the docking assembly to facilitate the detachment of the movable seat.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Through the arrangement of the first connecting assembly and the second connecting assembly, after the multiple unit modules are laid out in sequence on the inner wall of the storage tank to form a surface, the connecting seat is arranged at the knot of the unit module through the first connecting assembly. After the multiple connecting seats are laid out in sequence, the horizontal and vertical bars are laid out, and the horizontal and vertical bars are installed on the connecting seat through the second connecting assembly. The horizontal bars can connect the multiple connecting seats arranged in series, improving the flatness between the multiple unit modules arranged in series. The vertical bars can connect the multiple connecting seats arranged in series, improving the flatness between the multiple unit modules arranged in series. This greatly improves the flatness of the shielding layer, facilitates subsequent welding operations, and thus improves the laying quality of the shielding layer.

[0027] 2. Through the provision of movable seats and pressing plates, there is a certain probability that the corners of the unit modules will warp and deform during the manufacturing, transportation, and laying process. When the corners of the unit modules warp and deform, movable seats are installed between the four adjacent connecting seats according to the warping position, and the pressing plates of the movable seats flatten the warping positions to facilitate subsequent welding operations between the corners of adjacent unit modules. By providing a flip telescopic rod, the movable seat is slidably installed in the flattening area, so that the position of the movable seat can be appropriately adjusted according to the warping position of the unit module, thereby improving the flexibility of the overall structure.

[0028] 3. Through the setting of the limit block and the limit slot, after the movable seat is installed in the flattening area, a certain pressure is applied to the force-applying pressure plate, driving the pressure plate to press against the warped parts at the corners of the unit module to restore the warped parts of the unit module; after the pressure plate presses against the warped parts of the unit module, the force-applying pressure plate is rotated to drive the limit block to rotate the limit slot, so that the pressure plate remains pressed against the unit module, thereby improving the operational convenience of restoring the warped parts of the unit module.

[0041] Reference Figure 2 、 Figure 3 A shielding layer leveling device includes a connecting seat 1, horizontal bars 2 and vertical bars 3. The connecting seat 1 is installed on the unit module 7, and multiple connecting seats 1 are arranged in the horizontal and vertical directions. The multiple connecting seats 1 are respectively arranged on different unit modules 7; the connecting seat 1 is provided with a first connecting component 4, and the connecting seat 1 can be detachably installed at the knot 71 of the unit module 7 through the first connecting component 4.

[0042] Reference Figure 3 、 Figure 4 The first connecting component 4 includes a fixed clamping block 41, a movable clamping block 42 and a driving member 43. The fixed clamping block 41 is fixedly connected to the bottom wall of the connecting base 1, and the movable clamping block 42 is slidably installed on the bottom wall of the connecting base 1 and can approach or move away from the fixed clamping block 41. A clamping area 44 is formed between the fixed clamping block 41 and the movable clamping block 42, and the clamping area 44 is used for the flower knot 71 of the unit module 7 to be embedded.

[0043] A driving member 43 is provided on the bottom wall of the connecting base 1 to push the movable clamp 42 toward the fixed clamp 41. In this embodiment, the driving member 43 is configured as a quick clamp (a quick clamp is a conventional structure and its structure is not elaborated in detail here). The quick clamp is installed on the bottom wall of the connecting base 1 and is located on the side of the movable clamp 42 away from the fixed clamp 41. The quick clamp pushes the movable clamp 42 to reduce the clamping area 44, allowing the fixed clamp 41 and the movable clamp 42 to be clamped together on the knot 71 of the unit module 7, thereby allowing the connecting base 1 to be removably mounted on the unit module 7.

[0044] Reference Figure 3 、 Figure 4 、 Figure 5 The cam 721 of the fixing plate 71 is fixed to the top of the fixing plate 72, and the fixing plate 722 is fixed to the bottom of the fixing plate 72.

[0045] Reference Figure 3 、 Figure 5 、 Figure 6 There are multiple horizontal bars 2 and vertical bars 3. The horizontal bars 2 are used to connect multiple connecting seats 1 arranged horizontally in series, and the vertical bars 3 are used to connect multiple connecting seats 1 arranged vertically in series. A second connecting component 5 is provided on each connecting seat 1, and the horizontal bars 2 and vertical bars 3 are detachably installed on the connecting seat 1 through the second connecting component 5.

[0046] In this embodiment, the second connecting component 5 includes a connecting column 51 and a leveling sleeve 52. The connecting column 51 is fixedly installed on the upper surface of the connecting seat 1. The top wall of the connecting column 51 is respectively provided with a horizontal groove 511 for the horizontal bar 2 to be embedded and a vertical groove 512 for the vertical bar 3 to be embedded. The horizontal groove 511 and the vertical groove 512 are connected to each other and the horizontal groove 511 and the vertical groove 512 are cross-arranged; the leveling sleeve 52 is sleeved on the outer surface of one end of the connecting column 51 away from the connecting seat 1, and is threadedly connected to the outer peripheral wall of the connecting column 51 (the thread is not shown in the figure).

[0047] Reference Figure 6The notches of the horizontal groove 511 and the vertical groove 512 both have chamfered surfaces 513; an abutment piece 53 is slidably installed at the connection between the horizontal groove 511 and the vertical groove 512, and a compression spring 54 is installed between the abutment piece 53 and the connecting column 51, one end of the compression spring 54 is fixedly connected to the abutment piece 53, and the other end is fixedly connected to the inner wall of the connecting column 51. When the horizontal bar 2 is inserted into the horizontal groove 511 and the vertical bar 3 is inserted into the vertical groove 512 and tightened by the leveling sleeve 52, the compression spring 54 is compressed and deformed and has elastic force; an avoidance groove (not shown in the figure) for the installation of the compression spring 54 needs to be provided at the connection between the horizontal groove 511 and the vertical groove 512, so that when the vertical bar 3 is inserted into the vertical groove 512, the vertical bar 3 can abut against the bottom wall of the vertical groove 512.

[0048] Reference Figure 3 、 Figure 5 It should be noted that, in this embodiment, both the horizontal bar 2 and the vertical bar 3 include a plurality of unit segments 31 connected end to end, and a docking piece is provided between two adjacent unit segments 31, and the two adjacent unit segments 31 are connected to each other through the docking piece; the docking piece of the horizontal bar 2 and the docking piece of the vertical bar 3 have the same structure, and the docking piece of the vertical bar 3 is used as an example for explanation. The docking piece structure of the horizontal bar 2 can be obtained similarly.

[0049] A docking rod 311 is fixedly installed at both ends of the unit segment 31, and the docking piece is configured as a docking sleeve 32. The two ends of the docking sleeve 32 are respectively sleeved on the outer peripheral walls of the docking rod 311 of the two adjacent unit segments 31. The docking sleeve 32 and the outer peripheral walls of the docking rod 311 of the two adjacent unit segments 31 are both threadedly connected (the thread is not shown in the figure), and the two adjacent unit segments 31 are detachably connected through the docking sleeve 32.

[0050] The implementation principle of Example 1 of the present application is: after multiple unit modules 7 are laid out in sequence on the inner wall of the storage tank to form a surface, the connecting seat 1 is arranged at the flower knot 71 of the unit module 7 through the first connecting component 4. After multiple connecting seats 1 are arranged in sequence, the horizontal bars 2 and the vertical bars 3 are assembled, and then the horizontal bars 2 are embedded in the horizontal grooves 511 of the connecting columns 51 of the multiple connecting seats 1, and the vertical bars 3 are embedded in the vertical grooves 512 of the connecting columns 51 of the multiple connecting seats 1, so that the horizontal bars 2 can connect in series the multiple connecting seats 1 arranged horizontally, and the vertical bars 3 can connect in series the multiple connecting seats 1 arranged vertically.

[0051] Then, the leveling sleeve 52 is installed on the outer peripheral wall of the connecting column 51 of each connecting seat 1 in turn, and the leveling sleeve 52 is rotated in turn so that the leveling sleeve 52 can press the horizontal bar 2 and the vertical bar 3, thereby improving the flatness between the multiple unit modules 7 arranged horizontally and the multiple unit modules 7 arranged vertically, greatly improving the flatness of the shielding layer, facilitating subsequent welding operations, and further improving the laying quality of the shielding layer.

[0052] Example 2:

[0053] An embodiment of the present application discloses a shielding layer leveling device.

[0054] The difference between the shielding layer leveling device disclosed in the embodiment of the present application and embodiment 1 is that:

[0055] Reference Figure 7 、 Figure 8 In this embodiment, for the convenience of description, the area between four adjacent connecting seats 1 is defined as a flattening area 11; a movable seat 6 is provided in the flattening area 11, and a flip telescopic rod 62 is provided between the movable seat 6 and the four adjacent connecting seats 1. The movable seat 6 is slidably installed in the flattening area 11 through multiple flip telescopic rods 62 so that it can slide along the length direction of the horizontal bar 2 or the length direction of the vertical bar 3.

[0056] The flip telescopic rod 62 includes a first connecting rod 621 and a second connecting rod 622. A rotating rod 12 is fixedly installed on the surface of the connecting seat 1. One end of the first connecting rod 621 is provided with a rotating groove 624 for inserting the rotating rod 12. One end of the first connecting rod 621 is hinged to the upper surface of the connecting seat 1 through the rotating rod 12, and the other end of the first connecting rod 621 is provided with an insertion groove 623; one end of the second connecting rod 622 is hinged to the outer wall of the movable seat 6, and the other end is slidably inserted into the insertion groove 623.

[0057] The rotating rod 12 is provided with a docking piece, and the first connecting rod 621 is detachably mounted on the rotating rod 12 through the docking piece. In this embodiment, the docking piece is configured as a docking nut (not shown in the figure), which is sleeved on the outer peripheral wall of the rotating rod 12 and threadedly connected to the outer peripheral wall of the rotating rod 12. The end of the first connecting rod 621 away from the second connecting rod 622 is located between the docking nut and the upper surface of the connecting seat 1. The first connecting rod 621 is detachably mounted on the rotating rod 12 of the connecting seat 1 through the docking nut.

[0058] Reference Figure 7 、 Figure 8 A lifting groove is provided on the top wall of the movable seat 6, in which a lifting rod 63 is slidably installed. The lower end of the lifting rod 63 passes through the lifting groove and is fixedly connected to a pressing plate 61. The pressing plate 61 is used to flatten the raised parts at the corners of the unit module 7. The pressing plate 61 is slidably installed on the movable seat 6 through the lifting rod 63.

[0059] A return spring 64 is provided between the pressure plate 61 and the movable seat 6. The return spring 64 is sleeved on the outer peripheral side of the lifting rod 63. One end of the return spring 64 is fixedly connected to the pressure plate 61, and the other end is fixedly connected to the bottom wall of the movable seat 6. Under normal circumstances, the return spring 64 forces the pressure plate 61 to separate from the surface of the unit module 7.

[0060] The upper end of the lifting rod 63 passes through the lifting slot and is rotatably installed with a force-applying pressure plate 65. Two connecting frames 652 are fixedly installed on the outer peripheral wall of the force-applying pressure plate 65. The two connecting frames 652 are arranged at intervals around the central axis of the force-applying pressure plate 65. A limiting block 651 is fixedly installed on the end of each connecting frame 652 away from the force-applying pressure plate 65. Two sliding slots 66 are provided on the outer peripheral wall of the movable seat 6. The two ends of the sliding slot 66 extend along the sliding direction of the lifting rod 63. The two sliding slots 66 are corresponding to the two connecting frames 652. The limiting block 651 of each connecting frame 652 slides and is embedded in the corresponding sliding slot 66.

[0061] The outer wall of the movable seat 6 is provided with a stop slot 661 that communicates with the sliding slot 66. When the force-applying pressure plate 65 is rotated and forces the stop block 651 into the stop slot 661, the pressing plate 61 is pressed against the surface of the unit module 7. It should be noted that in this embodiment, the movable seat 6 is provided to restore the unit module 7 if the corners are warped. If the corners of the unit module 7 within the flattening area 11 are not warped, the movable seat 6 does not need to be installed.

[0062] The implementation principle of Example 2 of the present application is: during the manufacturing, transportation and laying process of the unit module 7, there is a certain probability that the corners of the unit module 7 will be warped and deformed. When the corners of the unit module 7 are warped and deformed, a movable seat 6 is installed between the four adjacent connecting seats 1 according to the warping position.

[0063] After the movable seat 6 is installed, the position of the movable seat 6 is adjusted so that the pressure plate 61 is transferred to the upper part of the raised part of the corner of the unit module 7. Then, a certain pressure is applied to the pressure plate 65 to force the pressure plate 61 to press against the raised part of the corner of the unit module 7 to restore the raised part. After the pressure plate 61 presses against the raised part of the corner of the unit module 7, the pressure plate 61 is rotated to force the limit block 651 to fit into the limit groove 661. Due to the elastic force of the return spring 64 reacting on the pressure plate 65, the limit block 651 is not easily separated from the limit groove 661, thereby keeping the pressure plate 61 pressed against the raised part of the corner of the unit module 7. At this time, the surrounding area of ​​the raised part (i.e., the surrounding area of ​​the pressure plate 61) can be spot welded with a welding gun, and then the movable seat 6 can be removed to improve the laying effect of the shielding layer.

[0064] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
