[0034] The preferred embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0035] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0036] In the rapidly developing modern urbanization process, urban expansion is like an unstoppable force, which not only witnesses the brilliant achievements of human civilization, but also brings unprecedented pressure and challenges to land resources. For urban river tunnels, immersed tube tunnels are more flexible in connecting with the roads on both sides of the water, which can greatly save urban land resources and have great promotion significance.

[0037] At present, immersed tube tunnels built in inland river basins are generally 4 to 6 lanes. The spacing between the two lifting mechanisms on the existing immersed tube installation barge is generally fixed or has a small adjustment range, which is only suitable for a single tunnel project. When the width of the immersed tube tunnel of the next project changes too much, the installation barge may be unusable or require additional modification.

[0038] In view of the above problems, an embodiment of the present application provides an immersed tube installation barge with adjustable lifting width, which can adapt to the lifting distances of immersed tubes 5 of different specifications and can be widely used in different immersed tube 5 tunnel projects.

[0039] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0040] Figure 1 It is a front view of the immersed tube installation barge with adjustable lifting width shown in an embodiment of the present application.

[0041] like Figures 1 to 7 As shown, a submerged tube installation barge with adjustable hoisting width provided in Example 1 of the present application includes:

[0042] The barge body 1 has slots 10 symmetrically arranged on both sides thereof, and reinforcement beams 11 are arranged at the slots 10;

[0043] A hoisting base 2 is arranged on the barge body 1, and the hoisting base 2 has two mounting grooves 20 which are parallel to each other and located on both sides of the slot 10, and the mounting groove 20 is provided with a plurality of pin holes which are distributed side by side along the width direction of the barge body 1;

[0044] The lifting device 3 is used for lifting the submerged pipe 5. The lifting device 3 is slidably matched with the installation groove 20. The lifting device 3 is provided with a plurality of axial holes matched with the pin holes. The axial holes are provided with pin shafts 31, and the pin shafts 31 are penetrated by the pin holes.

[0045] The barge body 1 is a separate hull, and at least two slots 10 are symmetrically provided on both sides of the hull. The slots 10 correspond to the center lines of the fore and stern of the barge body 1. The slots 10 are arranged in a rectangular opening structure and are recessed inwardly along the width direction of the barge body 1. The lifting device 3 is lifted and lowered in the slots 10. In order to ensure the strength of both sides of the barge body 1, reinforcing beams 11 can also be arranged at the slots 10 without affecting the lifting work of the lifting device 3. The number of reinforcing beams 11 can be set according to the inward recessed depth of the slots 10. The reinforcing beams 11 are respectively connected to the two side walls of the slots 10. By setting the inwardly recessed slots 10, the minimum lifting range can be adjusted so that it can float the submerged tube 5 that is smaller than the length of the barge body 1, and prevent the cable of the lifting device 3 from squeezing the barge body 1. The slots 10 on both sides of the barge body 1 are symmetrically arranged to ensure that the lifting point of the submerged tube 5 and the hook 36 of the barge lifting device 3 are in a vertical line, which can improve the stability of the submerged tube 5 during the floating process and ensure the force balance of each lifting device 3. The upper surface of the barge body 1 is a steel deck, and the lifting base 2 is installed on the barge body 1 by welding or bolting. The lifting base 2 is provided with pin holes for fixing the lifting device 3, and the distance between the pin holes can be set according to the specification parameters of the submerged tube 5. In some embodiments, the movement of the lifting device 3 can be carried out by setting a mechanical transmission or a manual transmission. The position of the lifting device 3 on the lifting base 2 is adjusted according to the size of the submerged tube 5. After aligning the pin hole and the shaft hole, it can be locked and fixed by the pin shaft 31.

[0046] In this embodiment, the lifting base 2 is located on both sides of the slot 10 of the barge body 1. By changing the position of the lifting device 3 on the lifting base 2, the lifting width between the lifting devices 3 can be adjusted, thereby meeting the floating installation requirements of immersed tubes 5 of different specifications, improving the applicability of the immersed tube installation barge, eliminating the need for modification, effectively improving the utilization rate of the immersed tube installation barge, and having the characteristic of convenient construction.

[0047] Example 2

[0048] In order to make the lifting base 2 and the lifting device 3 described in Example 1 have better maintainability and lifting stability, Example 2 of the present application also designs a corresponding structure. On the basis of the above Example 1, please refer to Figure 3 A pressure plate 21 is provided on one side of the mounting groove 20, and a fixing plate 30 is provided on the lifting device 3. The clamping connection between the pressure plate 21 and the fixing plate 30 enhances the stability of the lifting device 3 when adjusting the position, so as to prevent the lifting device 3 from tipping over during the movement. Figure 4The mounting groove 20 in Example 2 of the present application is detachably provided with a pressure plate 21 on one side away from the groove 10. The pressure plate 21 is a steel plate. The pressure plate 21 is parallel to the plane of the barge body 1, and one end of the pressure plate 21 extends toward the direction of the slot 10. The lifting device 3 is provided with a fixing plate 30 that is clamped with the pressure plate 21.

[0049] The pressing plate 21 is arranged on a side wall of the installation groove 20 away from the groove 10 and extends toward the groove 10. A limiting space is formed between the pressing plate 21 and the installation groove 20. After the lifting device 3 is placed in the installation groove 20, the fixing plate 30 clamps the pressing plate 21 to provide a pulling force to resist overturning for the lifting device 3. After the pin 31 is pulled out, the lifting device 3 can be fixed on the hoisting base 2 by the pressing plate 21 and the fixing plate 30. When assembling the lifting device 3, the lifting device 3 is lifted by a lifting device such as a portal crane and placed in the installation groove 20. When adjusting the position of the lifting device 3, the lifting device 3 can be pushed to slide in the installation groove 20 by manual transmission or mechanical transmission.

[0050] Therefore, after setting the pressure plate 21 and the fixing plate 30, the lifting device 3 can be limited on the lifting base 2, so that after the pin shaft 31 is pulled out, it is ensured that the lifting device 3 will not exceed the range of the support point due to its own center of gravity, thereby avoiding overturning, which can improve the safety when adjusting the position of the lifting device 3.

[0051] In this embodiment, the mounting groove 20 can be composed of two steel plates parallel to each other and vertically arranged on the barge body 1, and the steel plates and the barge body 1 can be fixed by bolting or welding. The pressing plate 21 is fixed to the steel plate by welding or bolting. In a preferred embodiment, the pressing plate 21 is installed on the steel plate by bolts, which is convenient for disassembling and repairing the lifting device 3.

[0052] For further information, see Figure 8 The lifting device 3 includes a winch 32, a hanger 33, a movable pulley 34, a fixed pulley 35, a hook 36 and a steel rope 37. The winch 32 is fixedly mounted on the barge body 1, the fixed pulley 35 is mounted on the hanger 33, the movable pulley 34 is connected to the hook 36, the steel rope 37 passes through the movable pulley 34 and the fixed pulley 35 and is connected to the winch 32, the hanger 33 is slidably matched with the mounting groove 20, and the fixing plate 30 is horizontally arranged on a side surface of the hanger 33 away from the groove 10.

[0053] Furthermore, when manual transmission is adopted, in order to improve the efficiency of manually pushing the lifting device 3 to move, based on the above specific implementation, please refer to Fig. 9The top of the hanger 33 of the immersed tube installation barge with adjustable lifting width is provided with an inwardly recessed slot 330, and the rotating shaft of the fixed pulley 35 is accommodated in the slot 330. The hanger 33 is detachably connected with a mounting plate 331, and the mounting plate 331 is buckled in the slot 330 so that the fixed pulley 35 can be locked on the hanger 33.

[0054] The fixed pulley 35 and the hanger 33 in the lifting device 3 are designed to be split and detachable, so that the fixed pulley 35 and the movable pulley 34 can be easily removed from the hanger 33, thereby reducing the resistance encountered when the hanger 33 is moved manually or mechanically. In addition, when the immersed tube installation barge is not used for a long time, the fixed pulley 35 and the hook 36 can be removed to avoid the problem of corrosion of the fixed pulley 35, the movable pulley 34 and other components due to long-term exposure to the outdoors.

[0055] Furthermore, the installation groove 20 is paved with a stainless steel plate 22, and a lubricating oil layer is provided between the stainless steel plate 22 and the hanger 33. The stainless steel plate 22 is a wear-resistant plate, and its smooth surface and lubricating oil layer can reduce the friction between the stainless steel plate 22 and the hanger 33.

[0056] Furthermore, a steel roller set matching the mounting groove 20 is provided at the bottom of the lifting device 3. Under this setting, the hanger 33 and the stainless steel plate 22 are in rolling cooperation, further reducing the friction between the two, so that a single person can also push the hanger 33 to move.

[0057] Furthermore, a plurality of reinforcing steel beams 4 are also provided at the bottom of the barge body 1. Figure 2 The reinforcing steel beam 4 is located at the bottom of the barge body 1. During the docking of the immersed tube 5, the reinforcing steel beam 4 can leave a certain distance between the barge body 1 and the immersed tube 5, ensuring that the steel rope 37 will not be clamped between the barge body 1 and the immersed tube 5 and avoid other objects that need to be placed on the top of the immersed tube 5. During the docking of the immersed tube 5, the movable pulley 34 and the hook 36 are lifted to the end surface of the reinforcing steel beam 4 by the winch 32. After adjusting the position of the lifting device 3 so that it can adapt to the current width of the immersed tube 5, the operator can lower the hook 36 by the winch 32. After the hook 36 is connected to the hanging ear of the immersed tube 5, the entire tube can be floated and installed.

[0058] Example 3

[0059] In Example 2, although the lifting spacing can be adjusted by manual pushing, there are problems of low efficiency, time-consuming and labor-intensive. In order to reduce labor costs and improve construction efficiency, on the basis of Example 2, the above-mentioned immersed tube installation barge with adjustable lifting width also includes a driving mechanism (not shown) for driving the lifting device 3 to move relative to the barge body 1. The driving mechanism can be a hydraulic cylinder, belt drive, electric push rod, screw drive, etc. When a hydraulic cylinder or electric push rod is used, the hydraulic cylinder and the electric push rod are installed and fixed on the barge body 1, and their output shafts are connected to the hanger 33. When a belt drive or screw drive is used, the motor connected to the belt or screw is installed and fixed on the barge body 1, and the hanger 33 is provided with a gear meshing with the belt or a slider threadedly connected to the screw.

[0060] Example 4

[0061] The embodiment 4 of the present application further simplifies the structure of the immersed tube installation barge, and uses the winch 32 to pull the hanger 33 to make reciprocating movements on the installation groove 20, eliminating the need to install a driving mechanism on the barge body 1. For details, please refer to Figure 5 The immersed tube installation barge with adjustable hoisting width of Example 4 of the present application further includes a cable 38 and a roller structure 39. The winch 32 and the two sides of the hanger 33 (i.e., the two ends along the slot 10) are provided with mounting ears for connecting the cable 38, and the two ends of the cable 38 are connected with mounting quick-release lock buckles. When the winch 32 rotates, the cable 38 is wound on the winding mechanism of the winch 32, and the roller structure 39 is used to adjust the pulling direction of the winch 32 to ensure that the cable 38, under the adjustment of the roller structure 39, the pulling force of the cable 38 pulling the hanger 33 and the moving direction of the hanger 33 can be on the same straight line. In specific implementation, the hook 36 is first moved down a certain distance by the winch 32, so that there is enough space between the movable pulley 34 and the fixed pulley 35 for the winch 32 to move when the winch 32 rotates, and the movable pulley 34 and the fixed pulley 35 are prevented from bumping against each other. After the hook 36 is moved down a certain distance, the quick release buckles at both ends of the cable 38 are respectively locked on the mounting ears of the winch 32 and the mounting ears of the hanger 33 close to the winch 32. At this time, the hanger 33 can be pulled toward the center of the barge body 1 by forward rotation. When it is necessary to increase the lifting distance of the two lifting devices 3, the quick release buckles 38 at both ends of the cable 38 lock the hanger 33 on the mounting ears away from the winch 32, so as to increase the lifting distance.

[0062] It is understandable that the winch 32 can also achieve the movement of the hanger 33 toward the center of the barge body 1 by reverse rotation, and the need to operate the lower hook 36 can be omitted.

[0063] In summary, after completing the previous immersed tube tunnel project, the relative position of the hanger 33 on the lifting base 2 can be achieved through the cooperation between the winch 32, the cable 38 and the mounting ears on both sides of the hanger 33 according to the requirements of the next immersed tube tunnel project, eliminating the need to set a driving mechanism on the barge body 1 and reducing the ship construction cost.

[0064] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
