Description

Technical Field

[0001] The present invention relates to the technical field of LNG ship cargo tank enclosures, and more particularly, to an auxiliary support device for installing top components of an LNG ship. Background Art

[0002] An LNG ship is a ship for transporting liquefied natural gas at -163°C. In the No. 96 membrane containment system cargo tank, there is a secondary shielding layer and a secondary membrane, a main shielding nb layer and a main membrane. The No. 96 cargo tank enclosure system is designed with ten cargo tank surfaces. The main structures of the secondary shielding layer and the main shielding layer are composed of insulation boxes and installed on these ten cargo tank surfaces. Inside the cargo tank, there are several layers of retractable scaffolding structures to enable workers to reach each bulkhead surface for installation, welding and other work of various components of the enclosure system. Connecting piece bases are welded on each surface of the cargo tank and fixed to the hull. There are nuts inside the bases. When installing many components, various operations are carried out by means of tooling that can connect to the nuts inside the bases.

[0003] For the installation of the secondary box on the top of the cargo tank, after installation, it is necessary to wait for 24 hours for the resin to harden and then replace it with fixed fasteners. Therefore, there are no strict time requirements for the temporary fixing tooling. However, for the installation of other components, such as the insulation boxes on the top main layer, the Invar prefabricated parts on the top, and the composite beams, etc., temporary support is required during installation and then they are immediately fixed by means of fasteners or screwing. Then the spider clips of the secondary box need to occupy the fixing method of the fasteners and are inconvenient to use at this time. For the installation of the main box, if the spider clip tooling is used for temporary fixing, this fixing method occupies the installation position of its fasteners. When the fasteners need to be replaced later, the spider clip tooling needs to be removed and replaced. And the main box has no resin and can be immediately fixed with fasteners after being installed in place. Therefore, when using a temporary fastening tooling similar to a spider clip, since it occupies the position of the fasteners, it needs to be immediately removed and replaced when replacing the fasteners, which causes a great waste of working hours. And some components installed on the top cannot be fixed by means of the spider clip tooling by using the connecting piece position.

[0004] Therefore, a fixing device that does not occupy the position of the fasteners and can provide convenient and fast support for the installation of top components of the liquid cargo tank is very necessary. Summary of the Invention

[0035] Please refer to Figure 1 and Figure 2 , this embodiment provides an auxiliary support device 100 for installing top components of an LNG ship. The auxiliary support device 100 for installing top components of an LNG ship includes a main rod body 110, a first connection assembly 120, a first support seat 130, a second support seat 140, and a second connection assembly 150;

[0036] The first support seat 130 is movably connected to one end of the main rod body 110 through the first connection assembly 120, and the second support seat 140 is movably connected to the other end of the main rod body 110 through the second connection assembly 150;

[0037] Among them, the main rod body 110 is used to rotate under the action of an external force, and then drive one or both of the first support base 130 and the second support base 140 to move along the axis direction of the main rod body 110, so that the first support base 130 and the second support base 140 respectively abut against the main box 200 and the scaffolding platform 300.

[0038] Please refer to Figure 1 and Figure 2 , the working principle of the auxiliary support device 100 for installing the top components of the LNG ship is as follows:

[0039] The auxiliary support device 100 for installing the top components of the LNG ship includes a main rod body 110, a first connection assembly 120, a first support base 130, a second support base 140, and a second connection assembly 150;

[0040] Among them, the first support base 130 is movably connected to one end of the main rod body 110 through the first connection assembly 120, and the second support base 140 is movably connected to the other end of the main rod body 110 through the second connection assembly 150; thus, the positions of the first support base 130 and the second support base 140 can be adjusted by the movement of the first support base 130 and the second support base 140 relative to the main rod body 110;

[0041] Based on this, since the first support base 130 and the second support base 140 are respectively used to abut against the main box 200 and the scaffolding platform 300, thus, when adjusting the positions of the first support base 130 and the second support base 140, by applying an external force to the main rod body 110, the main rod body 110 can be rotated, and then drive one or both of the first support base 130 and the second support base 140 to move along the axis direction of the main rod body 110, so that the first support base 130 and the second support base 140 respectively move to the positions where they abut against the main box 200 and the scaffolding platform 300, thereby playing a supporting role, and further facilitating the installation of related components, and its disassembly and assembly method is convenient, rotating the main rod body 110 in the opposite direction can release the connection, so as to simplify its operation and improve the operation efficiency;

[0042] In summary, the auxiliary support device 100 for installing the top components of the LNG ship can provide temporary support for the installation of the top components of the cargo tank, and its structure is simple, the installation is convenient, the operation efficiency is high, and the work efficiency can be improved.

[0043] Furthermore, please refer to Figure 1 and Figure 2In this embodiment, since the first support base 130 and the second support base 140 are used to abut against the main box 200 and the scaffolding platform 300 respectively, based on this, in order to facilitate the rapid adjustment of the distance between the first support base 130 and the second support base 140, the main rod body 110 can be set in a telescopic structure; specifically, the main rod body 110 can include a first rod body 111 and a second rod body 112, and a portion of the first rod body 111 extends into the second rod body 112 and is slidably matched with the second rod body 112;

[0044] The first connecting assembly 120 is connected to an end of the first rod 111 outside the second rod 112 , and the second connecting assembly 150 is connected to an end of the second rod 112 facing away from the first rod 111 .

[0045] Thus, by extending part of the first rod 111 into the second rod 112 and adjusting the length of the extended part, the support height of the main rod 110 can be adjusted to adapt to the distance between the main box 200 and the scaffolding platform 300, expand its adaptability, and facilitate its disassembly and assembly, that is, after the support is completed, the first rod 111 can be extended into the second rod 112 to release the support.

[0046] In order to prevent the first rod 111 and the second rod 112 from rotating relative to each other when the main rod 110 is rotated, the first rod 111 and the second rod 112 are both square rods.

[0047] During the supporting process, in order to maintain the supporting height of the main rod body 110, improve its stability, and expand its height adjustment range, the main rod body 110 further includes a limiting pin 113. The first rod body 111 is provided with a plurality of first positioning holes 114 spaced apart along its extension direction, and the second rod body 112 is provided with a plurality of second positioning holes 115 spaced apart along its extension direction. The limiting pin 113 cooperates with one of the first positioning holes 114 and a second positioning hole 115 corresponding to and connected to the first positioning hole 114. Thus, the position of the limiting pin 113 can be adjusted to cooperate with different first positioning holes 114 and second positioning holes 115, thereby adjusting and adapting to different spacings between the main box 200 and the scaffolding platform 300. Moreover, such a setting method can also release the connection between the first rod body 111 and the second rod body 112 by removing the limiting pin 113, thereby facilitating its removal.

[0048] For further information, please refer to Figure 1 and Figure 2, in this embodiment, when configuring the first connection component 120 and the second connection component 150, their function is to enable both the first support base 130 and the second support base 140 to be movably connected to the main rod body 110. Specifically, they are respectively movably connected to the first rod 111 and the second rod 112. Therefore, the first connection component 120 includes a first connection nut 121 and a first threaded shaft 122; the first connection nut 121 is connected to the first rod 111, the first threaded shaft 122 is threadedly connected to the first connection nut 121, and the first threaded shaft 122 is connected to the first support base 130;

[0049] The second connection component 150 includes a second connection nut 151 and a second threaded shaft 152; the second connection nut 151 is connected to the second rod 112, the second threaded shaft 152 is threadedly connected to the second connection nut 151, and the second threaded shaft 152 is connected to the second support base 140;

[0050] Thus, by enabling the relative rotation between the first connection nut 121 and the first threaded shaft 122, the first threaded shaft 122 can move relative to the first connection nut 121, thereby adjusting the position of the first support base 130 relative to the first rod 111. Similarly, by enabling the relative rotation between the second connection nut 151 and the second threaded shaft 152, the second threaded shaft 152 can move relative to the second connection nut 151, thereby adjusting the position of the second support base 140 relative to the second rod 112. Through this setting method and based on the structure of the above-mentioned main rod body 110, the rotation of the main rod body 110 can drive the movement of the first support base 130 and the second support base 140;

[0051] It should be noted that in order to enable the first support base 130 and the second support base 140 to approach or move away from each other when the main rod body 110 rotates, thereby adjusting their support height, the thread helix direction of the first threaded shaft 122 can be made opposite to that of the second threaded shaft 152.

[0052] In addition, to improve its adaptability, the first support base 130 is hinged to the first threaded shaft 122, and the second support base 140 is hinged to the second threaded shaft 152. And to improve its adjustable height, the first connection nut 121 is communicated with the first rod 111 for the first threaded shaft 122 to extend into the first rod 111; the second connection nut 151 is communicated with the second rod 112 for the second threaded shaft 152 to extend into the second rod 112.

[0053] In summary, please refer to Figure 1 and Figure 2 , the auxiliary support device 100 for installing the top components of the LNG ship can provide temporary, convenient and fast support for installing components such as the main layer insulation box and Invar prefabricated parts at the top of the current liquid cargo tank;

[0054] Taking the installation of the top main layer insulation box as an example:

[0055] First, adjust the support height of the main rod body 110 of the auxiliary support device 100 for installing the top components of the LNG ship, that is, adjust the installation position of the limit pin 113;

[0056] After placing the top main layer insulation box at the corresponding installation position on the top, first support it temporarily by hand; then stand the auxiliary support device 100 for installing the top components of the LNG ship between the scaffolding platform 300 and the main box 200, step on the first support base 130 on the side of the scaffolding platform 300, hold the first rod body 111 or the second rod body 112 of the main rod body 110 with both hands, and rotate it. Through the rotation of the main rod body 110, the first threaded shaft 122 and the first connecting nut 121 move relative to each other in a threaded movable connection manner, and the second threaded shaft 152 and the second connecting nut 151 move relative to each other, thereby adjusting the positions of the first support base 130 and the second support base 140, that is, adjusting the support height of the auxiliary support device 100 for installing the top components of the LNG ship until the support height can support the main layer insulation box;

[0057] Moreover, with the above structural setting method, part of the angular inclination between the scaffolding platform 300 and the main layer insulation box can be offset by the first support base 130 and the second support base 140. Since this device does not need to occupy the fastener position of the main box 200, the 4 insulation boxes adjacent to the same fastener can be immediately fixed with fasteners after installation. When the pressure plates at the three corners on a single main layer insulation box are fastened to the fasteners, the main rod body 110 can be rotated in the reverse direction to remove the device;

[0058] When subsequently supporting the main box 200, this device can continue to be used directly by rotating and adjusting the lengths of the first threaded shaft 122 and the second threaded shaft 152.

[0059] As described above, the auxiliary support device 100 for installing the top components of the LNG ship has the following advantages:

[0060] This device does not occupy the fastener position during use, and the adjacent main boxes 200 can be immediately fixed with fasteners after installation;

[0061] The support device is convenient to use and can effectively improve work efficiency.

[0062] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
