Detailed Implementation

[0046] The technical solutions of this application are described in detail below with reference to specific embodiments. However, it should be understood that, without further description, the elements, structures and features in one embodiment can also be beneficially incorporated into other embodiments.

[0047] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0048] In the description of this application, it should be understood that the terms "upper," "lower," "bottom," "inner," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] The first embodiment of this application provides a lifting-type ship pipe connection device (hereinafter referred to as the connection device, such as...). Figure 1-12 As shown), it is installed between the immersed tunnel transport vessel 100 and the immersed tunnel 200. The connecting device includes a lifting device 1 and a moving component 2; wherein,

[0051] like Figure 3 As shown, the lifting device 1 is installed on the immersed tunnel transport vessel 100 and has a force transmission component 101 for lifting, which is installed at the first end of the motion component 2; the force transmission component 101 may be a cable for lifting and lowering the motion component 2. The lifting device 1 may be a hoisting device commonly used in the prior art.

[0052] like Figure 3-5 As shown, the motion component 2 includes a slider 201 and a crossbeam 202. The slider 201 can slide up and down along the immersed tunnel transport vessel 100; the crossbeam 202 is connected to the slider 201 so that it moves together with the slider 201 under the action of the lifting device 1. In one embodiment, the slider 201 and the crossbeam 202 can also be an integral structure.

[0053] The force transmission component 101 of the lifting device 1 can be installed on the slider 201 or the crossbeam 202 to lift or lower the motion component 2.

[0054] A hanging column 203 is provided on the crossbeam 202, which extends downward in a direction perpendicular to the crossbeam 202.

[0055] In one embodiment, the first end 2031 of the hanging column can be fixedly installed on the crossbeam 202.

[0056] In another alternative embodiment, the first end 2031 of the suspension column is slidably connected to the crossbeam 202, such as... Figure 12As shown. Optionally, a drive device (not shown) capable of driving the hanging column 203 to move along the crossbeam 202 and a limiting device (not shown) restricting excessive movement of the hanging column 203 on the crossbeam 202 are provided between the hanging column 203 and the crossbeam 202. For example, the drive device can be a hydraulically driven push rod, the support of which is mounted on the crossbeam 202, and the push rod is connected to the hanging column 203 to drive the hanging column 203 to move. The limiting device can be a block that can extend and retract on the surface of the crossbeam. When the hanging column 203 needs to move on the crossbeam 202 to adjust its position, the block retracts into the surface of the crossbeam, not hindering the movement of the hanging column 203; when the hanging column 203 is in place, the block extends out of the surface of the crossbeam, limiting the position of the hanging column 203.

[0057] like Figure 4 and Figure 5 As shown, a groove 2033 is formed at the second end 2032 of the lifting column, opposite to the first end 2031. A hook 204 is provided in the groove 2032. The hook 204 can be connected to the lifting column 203 via a rotating shaft such as a pin 205, so that it can rotate to extend or be retracted upward into the groove 2033. The second end 2032 of the lifting column is also provided with an anti-rotation limiting block 206, which is located below the hook 204. It can limit the downward rotation limit position of the hook 204 and provide a supporting reaction force.

[0058] The hook 204 can be controlled by a rotary actuator (e.g., an electric actuator) so that it can rotate relative to the pin 205 to extend or retract into the groove 2033. This driving technology is conventional in the art and can be implemented using existing means.

[0059] When the hook 204 extends, the moving component 2 is approximately in a "T" shape (e.g., Figure 1 When the hook 204 retracts, the moving component 2 is roughly in a "T" shape (e.g., Figure 7 ).

[0060] like Figure 1-3 and Figure 12 As shown, the immersed tunnel transport vessel 100 has hulls 1001 located on opposite sides and a bridging frame 1002 connecting the two hulls 1001. The hull 1001 is provided with a vertical slide rail 1003 matching the slider 201 on the side near the motion component 2, so that the slider 201 can move up and down stably along the slide rail 1003 of the immersed tunnel transport vessel 100.

[0061] The immersed tube 200 is provided with a reverse bracket 2001 on the side near the motion component 2, and a receiving groove 2002 is formed on the immersed tube 200 to accommodate the hook 204, which can be used to lift the immersed tube 200 and raise and lower it together with the motion component 2.

[0062] like Figure 6 and Figure 10-12 As shown, the connecting device also includes a support 3 and a pad 4.

[0063] In the working state, the support 3 is located between the crossbeam 202 and the immersed tube 200; more specifically, the support 3 is located at the end of the crossbeam 202 away from the lifting device 1 (in other words, at the second end of the motion component 2, opposite to the first end of the motion component 2 on which the force transmission member 101 is installed); thus, when the force transmission member 101 lifts the crossbeam 202 upward, the support 3 can provide support force at the opposite end, preventing the crossbeam 202 from tilting downward. The support 3 can be made of, for example, concrete, wood, steel, or other materials.

[0064] A first positioning groove (not shown in the figure) can be provided on the top surface of the immersed tube 200 or the bottom surface of the crossbeam 202. The support 3 can be confined in the first positioning groove to prevent the support 3 from shifting during transportation.

[0065] In one embodiment, the connecting device is configured such that the point of application of the force transmission element 101 of the lifting device on the motion component 2 is the rotation center, and the lever arm of the supporting force of the support 3 on the crossbeam 202 relative to the rotation center is at least twice the lever arm of the force applied by the reverse bracket 2001 to the hook 204 relative to the rotation center.

[0066] The connecting device bears a large load, especially when the submerged pipe 200 is raised to reduce the draft, the load can reach hundreds of tons. The "T" shape with added support 3 allows the connecting device to maintain its stability under non-collinear stress conditions of the reverse corbel load and the lifting force. By placing the slider 201 closer to the lifting column 203 relative to the support 3, a "T" shaped structure with the horizontal stroke longer on the left and shorter on the right is formed. This minimizes the increase in reverse corbel stress caused by the support force of the support 3.

[0067] like Figure 6 , Figure 11 and Figure 12 As shown, in the working state, the support pier 4 is located between the crossbeam 202 and the bridge frame 1002, serving as a support and buffer, ensuring that the immersed tunnel transport vessel 100 and the moving component 2 are firmly secured together during transportation, thus improving transportation stability. The support pier 4 can be made of materials such as concrete, wood, or steel.

[0068] A second positioning groove (not shown in the figure) can be provided on the top surface of the crossbeam 202 or the bottom surface of the bridge frame 1002. The pad 4 can be confined in the second positioning groove to prevent the pad 4 from shifting during transportation.

[0069] The connecting device, under the influence of lifting force, immersed tube load, and the constraint of the sliding block, ensures the stability of the entire transportation system. The main function of the pier 4 is to increase the stability of the connecting device and immersed tube 100 under harsh sea conditions; it can be omitted in waters with better sea conditions.

[0070] The second embodiment of this application provides a immersed tube transport vessel 100, which has the lifting tube connection device described in any of the preceding embodiments.

[0071] like Figure 1-3 As shown, in one embodiment, every two lifting-type tube connection devices form a pair, symmetrically arranged on both sides of the immersed tube, located between the transport vessel 100 and the immersed tube 200 respectively. The immersed tube transport vessel 100 may have multiple pairs of lifting-type tube connection devices.

[0072] In one implementation, such as Figure 6 As shown, each pair of lifting tube connection devices shares a crossbeam 202, which extends from one side of the immersed tube 200 to the opposite side, and two sliders 201 are located at opposite ends of the same crossbeam 202.

[0073] Connecting the crossbeams 202 into one unit can give full play to the rigidity and load-bearing capacity of the crossbeams 202 themselves and enhance the stability of the stress system; however, when the width of the immersed tube is large, the length of the crossbeams may increase significantly; the selection of specific solutions can take into account the balance between enhancing structural performance and economy.

[0074] The third embodiment of this application provides a construction method for a lifting-type ship pipe connection device (hereinafter referred to as the construction method), which can use the lifting-type ship pipe connection device described in any of the preceding embodiments. The construction method includes the following steps:

[0075] S1 straddle: such as Figure 7 As shown, the immersed tube 200 is towed to the position between the two hulls 1001 of the immersed tube transport vessel 100, so that the immersed tube transport vessel 100 straddles the immersed tube 200 (that is, the two hulls 1001 are located on both sides of the immersed tube 200, and the bridging frame 1002 is located on the immersed tube 200).

[0076] S2 hook drop: as shown Figure 8 As shown, when the hook 204 is configured to rotate, the lifting device 1 is activated to lower the moving component 2, so that the hook 204 is below the bearing surface of the reverse bracket 2002, and the hook 204 is flipped downwards to enter the receiving groove 2002; or,

[0077] S2 Hook Drop: When the lifting column 203 is configured to slide on the crossbeam, the lifting device 1 is activated to lower the motion component 2, so that the hook 204 is lower than the bearing surface of the reverse bracket 2002, and the lifting column 203 is pushed towards the sinking tube side, so that the hook 204 enters the receiving groove 2002;

[0078] S3 Pre-lift: Start the lifting device 1 to lift the motion component 2, so that the hook 204 abuts against the bearing surface of the bracket 2002;

[0079] S4 support: such as Figure 9 As shown, the pier 3 is supported between the crossbeam 202 and the immersed tube 200;

[0080] S5 lift: such as Figure 10 As shown, the lifting device 1 is activated to lift the motion component 2, raising the immersed tube 200 to the preset position;

[0081] S6 support pad: such as Figure 11 and Figure 12 As shown, the pier 4 is placed between the bridge frame 1002 and the crossbeam 202 of the moving component 2.

[0082] Furthermore, the implementation method of the lifting-type ship pipe connection device described above is also applicable to this construction method, and will not be repeated here. In S2, different processing methods can be selected based on the different structures of the lifting column 203 and the hook 204. When the hook 204 can rotate and the lifting column 203 can also move, when the hook 204 is lower than the bearing surface of the reverse bracket 2002, it may be necessary to simultaneously flip the hook 204 downwards and push the lifting column 203 towards the immersed tube side so that the hook 204 enters the receiving groove 2002, thereby lifting the immersed tube. In the non-working state, the hook 204 can be flipped upwards around the pin axis and stored in the groove 2033 to achieve the separation and immersion installation of the immersed tube from the transport ship; or in the non-working state, the lifting column slides along the crossbeam away from the immersed tube, causing the hook to disengage from the receiving groove, thereby achieving the separation and immersion installation of the immersed tube from the transport ship.

[0083] The order of steps described in this embodiment is merely a descriptive order. In actual operation, it can be adjusted according to actual needs. Therefore, this descriptive order does not constitute an absolute limitation on this application.

[0084] The described embodiments are merely preferred embodiments of this application and are not intended to limit the scope of this application. Any modifications and improvements made by those skilled in the art to the technical solutions of this application without departing from the spirit of this application should fall within the protection scope defined by the claims of this application.
