Description

Technical Field

[0001] This invention belongs to the field of marine floating technology, and more specifically, relates to a floating pier connection structure. Background Technology

[0002] Articulated joints are a core technology for offshore floating structures and play a crucial role in floating piers. Floating piers can be over a kilometer long but only one or two meters high. If a purely rigid structure were used, it would be subjected to enormous wave moments, inevitably leading to breakage. Therefore, articulated joints are needed between floating units to release wave moments and ensure structural safety. Besides bearing significant loads, articulated joints also need to be assembled in the waves, requiring advanced technology and representing a challenge faced by both domestic and international companies. Based on years of experience in offshore use, especially in resisting wind and waves, the most important aspect of articulated joints, besides possessing sufficient strength and rigidity, facilitating assembly and connection, and ensuring the interchangeability of floating units, is solving the connection and assembly problem under the conditions of floating unit movement in wind and waves.

[0003] Existing floating bodies (multi-purpose floating boxes) utilize a hinged joint of the "slider-tube seat" type. This joint structure adopts the American concept and technology of hinged connections, consisting of a flexible connector and a shear connector. The flexible connector uses a double-hinged structure of slider and slide seat, bearing only tensile force. The shear connector uses a tube seat connection, bearing vertical shear force, lateral shear force, and compressive force, but not tensile force. This type of connector has strong resistance to wind and waves and sufficient strength and rigidity, but it cannot solve the problem of convenient and rapid assembly under unit motion conditions.

[0004] Existing technology includes a technology entitled "Box-Girder Combined Floating Bridge" with publication number "CN106480816B". This technology discloses a box-girder combined floating bridge, comprising multiple continuously spliced ​​floating bridge sections (1) and anchors (2) and anchor chains (3) for constraining the displacement of the floating bridge sections. Each floating bridge section (1) includes a pontoon (11) and trusses (12, 13) symmetrically fixed on both sides of the upper part of the pontoon (11), and also includes struts (14). The two ends of the struts (14) are respectively fixedly connected to the trusses (12, 13) on both sides of the upper part of the pontoon (1). The box-girder combined floating bridge of the present invention has strong resistance to longitudinal bending moment and torsion, and can effectively survive and be used under medium wave conditions. However, this technology does not address the technical problems and solutions of this application. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide a floating bridge connection structure that is simple in structure, facilitates the connection of floating bodies in wave motion, is beneficial to the rapid assembly and disassembly of floating bodies, greatly improves the assembly efficiency of floating bodies, shortens the assembly time of floating bodies, can fully release wave bending moment, ensures structural safety, and the articulated arm not only bears large tensile force, but also bears vertical shear force and lateral shear force, thereby comprehensively simplifying construction and improving the safety of use.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] This invention relates to a floating bridge connection structure, comprising a first float and a second float. A centering groove is provided at one end of the first float, and a hinged seat housing is provided on the upper part of one end of the first float. A guide post is provided on the hinged seat housing, and a positioning pin hole is provided on the guide post. A centering arm is provided at one end of the second float, and a hinged arm base is provided on the upper part of one end of the second float. A connecting shaft is provided on the hinged arm base, a positioning hole is provided at one end of the hinged arm, and a connecting hole is provided at the other end of the hinged arm. The positioning hole of the hinged arm is fitted onto the guide post, and the connecting hole of the hinged arm is fitted onto the connecting shaft.

[0008] The articulated seat box and the first float are an integral structure. One articulated seat box is provided on one side of the upper part of one end of the first float, and another articulated seat box is provided on the other side of the upper part of one end of the first float. The two articulated seat boxes are arranged symmetrically.

[0009] The articulated arm base and the second float are an integral structure. One articulated arm base is provided on one side of the upper part of one end of the second float, and another articulated arm base is provided on one side of the upper part of the other end of the second float. The two articulated arm bases are arranged symmetrically.

[0010] The guide post of the hinged seat box is perpendicular to the first float, the centering groove is perpendicular to the guide post, and the centering arm of the hinged arm base is perpendicular to the second float.

[0011] The hinged seat housing is provided with a recessed platform, a guide post is provided on the horizontal surface of the recessed platform, and a guide block is provided on the vertical surface of the recessed platform.

[0012] Two sealing plates on the second float protrude from the upper surface of the second float. Each axle of the hinged arm base is connected to a corresponding sealing plate by multiple fixed horizontal pins. A gap is provided between the two axles. Each end of the connecting shaft located in the gap is movably installed in the axle hole of one axle.

[0013] The positioning pin hole is a square hole, and a positioning pin is inserted into the positioning pin hole.

[0014] The hinged seat housing, hinged arm base, centering arm, guide post, connecting shaft, sealing plate, and positioning pin are all made of metal.

[0015] The articulated arm includes a connecting part and a positioning part, which are T-shaped. The connecting part has a connecting hole at one end, and the positioning part has a positioning hole on each side.

[0016] The working principle and beneficial effects of the technical solution adopted in this invention are as follows:

[0017] The floating bridge connection structure described in this invention is formed by connecting multiple floating bodies. Adjacent floating bodies are connected by a movable connection structure. During connection, the first and second floating bodies are positioned close together. When connecting, the centering arm at one end of the second floating body extends into the centering groove at one end of the first floating body, quickly achieving initial centering of the first and second floating bodies and restricting their movement within a certain range, facilitating the connection of the hinged arms. One end of the hinged arm is hinged to the connecting shaft on the hinged arm base of the second floating body, allowing it to flip up and down. After the hinged arm flips down, the positioning hole at the other end of the hinged arm can be engaged with the conical guide post, achieving horizontal positioning. Then, a positioning pin is inserted into the positioning pin hole on the guide post, achieving a reliable connection between the hinged arm and the guide post. This achieves a reliable connection between the first and second floating bodies. The movable structure allows for the release of wave bending moments, preventing easy breakage under external impact. The use of hinged joints between the floating body units ensures the structural safety of the assembled floating bridge. In addition to the fact that the connecting structure can withstand a large load, it is also convenient and quick to complete the splicing in the waves. After the first and second floats are initially aligned, the articulated arm can be flipped to accurately and quickly connect the articulated arm to the guide post, reducing the construction difficulty, improving the construction efficiency, effectively solving the problem of connection and assembly under the movement conditions of floats in wind and waves, and after connection, it can reliably withstand huge wave bending moments and will not easily separate and disintegrate.

[0028] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of the present invention, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0029] As attached Figure 1 -Appendix Figure 8As shown, this invention is a floating bridge connection structure, including a first float 1 and a second float 2. A centering groove 7 is provided at one end of the first float 1, and a hinged seat box 3 is provided on the upper part of one end of the first float 1. A guide post 8 is provided on the hinged seat box 3, and a positioning pin hole 9 is provided on the guide post 8. A centering arm 6 is provided at one end of the second float 2, and a hinged arm base 4 is provided on the upper part of one end of the second float 2. A connecting shaft 10 is provided on the hinged arm base 4. A positioning hole 11 is provided at one end of the hinged arm 5, and a connecting hole 12 is provided at the other end of the hinged arm 5. The positioning hole 11 of the hinged arm 5 is fitted onto the guide post 8, and the connecting hole 12 of the hinged arm 5 is fitted onto the connecting shaft 10. This structure addresses the shortcomings of the prior art by proposing an improved technical solution. In this structure, the entire floating bridge is formed by connecting multiple floats. Adjacent floats are connected by a movable connection structure. During connection, the first float 1 and the second float 2 are positioned close to each other. When they are connected, the centering arm 6 at one end of the second float 2 extends into the centering groove 7 at one end of the first float 1, quickly achieving initial centering of the first float 1 and the second float 2, restricting the movement of the two floats within a certain range, and facilitating the connection of the hinge arm 5. One end of the hinge arm 5 is hinged to the connecting shaft 10 on the hinge arm base 4 of the second float 2, allowing it to flip up and down. After the hinge arm 5 flips down, the positioning hole 11 at the other end of the hinge arm 5 can be engaged with the tapered guide post 8, achieving horizontal positioning. Then, a positioning pin 22 is inserted into the positioning pin hole 9 on the guide post 8, achieving a reliable connection between the hinge arm 5 and the guide post 8. In this way, a reliable connection is achieved between the first float 1 and the second float 2. Both are movable structures that can swing, releasing wave bending moments and preventing easy breakage under external impact. The use of hinged joints between the float units ensures the structural safety of the assembled floating bridge. Besides its ability to withstand significant loads, the connecting structure also facilitates quick and easy assembly in waves. After initial alignment of the first float 1 and the second float 2, simply flipping the hinged arm 5 allows for accurate and rapid connection between the hinged arm 5 and the guide post 8, reducing construction difficulty, improving efficiency, and solving the problem of connecting and assembling floats under wave conditions. Furthermore, the connected structure reliably withstands enormous wave moments and will not easily disintegrate. The floating pier connecting structure described in this invention is simple in structure, facilitates connection of floats in wave motion, and promotes rapid assembly and disassembly of floats, greatly improving assembly efficiency and shortening assembly time. It can fully release wave moments, ensuring structural safety. The hinged arm not only withstands high tensile forces but also bears vertical and lateral shear forces, thus comprehensively simplifying construction and improving operational safety.

[0030] The hinge seat housing 3 and the first float 1 are an integral structure. One hinge seat housing 3 is located on one upper side of one end of the first float 1, and another hinge seat housing 3 is located on the other upper side of one end of the first float 1. The two hinge seat housings 3 are arranged symmetrically. In this structure, the key component of the hinge seat housing 3 is the guide post, used to connect one end of the positioning hole of the hinge arm. Other components are used to reinforce the guide post and for welding the float module. The hinge seat housing 3 is located at the tail end of the first float, and the two hinge seat housings 3 on both sides are symmetrical along the longitudinal centerline of the module. The hinge seat housing includes a housing structure, a guide plate, and guide posts. The housing structure is welded from steel plates; the guide plate is also made of steel plates; each hinge seat housing 3 has two guide posts. The upper part of the guide post is conical with a square positioning pin hole, and the lower part is cylindrical, connected as a whole and welded to the housing structure.

[0031] The articulated arm base 4 and the second float 2 are an integral structure. One articulated arm base 4 is located on one upper side of one end of the second float 2, and another articulated arm base 4 is located on one upper side of the other end of the second float 2. The two articulated arm bases 4 are symmetrically arranged. This structure provides the articulated arm bases and their accessories for welding and connecting the float module and installing the articulated arm. The articulated arm base 4 is located at the bow end of the second float, and the two articulated arm bases 4 on both sides are symmetrical along the longitudinal centerline of the module. The articulated arm bases are made of casting material and are integrally welded to the second float. The articulated arm base 4 is equipped with a connecting shaft, two bearing seats, and multiple fixing cross pins 19. The connecting shaft is made of alloy steel; the bearing seats are also made of alloy steel. The bearing seats are mounted on the sealing plate of the articulated arm base via the fixing cross pins, and the sealing plate is fixedly connected to the second float.

[0032] The floating pier connection structure described in this invention is used for connecting heavy floating bodies at sea. Its main function is to connect two adjacent floating bodies into a whole, but it allows the floating bodies to rotate around the joint. Hinged joints are movable connections, subject to complex loads and high forces in wind and waves, and are difficult to align during assembly. To improve joint strength and assembly convenience, the hinged device adopts an assembly method of initial alignment of the centering groove and centering arm, followed by a flip-over connection of the hinged arm. A hinged seat box, a hinged arm base, a hinged arm, a centering arm, and a centering groove are respectively set at the ends of the two mating floating bodies. Initial alignment is achieved by inserting the centering arm into the centering groove, and then the hinged arm and the hinged seat box are flipped together for connection.

[0033] The guide post 8 of the hinged base 3 is perpendicular to the first float 1, the centering groove 7 is perpendicular to the guide post 8, and the centering arm 6 of the hinged arm base 4 is perpendicular to the second float 2. In this structure, the first float 1 and the second float 2 are close to each other. When they are connected, the centering arm 6 at one end of the second float 2 extends into the centering groove 7 at one end of the first float 1, quickly achieving initial centering of the first float 1 and the second float 2, restricting the movement of the two floats within a certain range, facilitating the connection of the hinged arm 5, and allowing the operator to quickly connect the positioning hole to the guide post.

[0034] The hinge seat housing 3 is provided with a recessed platform 13, and the guide post 8 is provided on the horizontal surface 14 of the recessed platform 13. The guide block 16 is provided on the vertical surface 15 of the recessed platform 13. The guide block (guide plate) 16 and the guide post 8 form a V-shaped connection port, which facilitates the hinge arm 5 to quickly and accurately connect to the guide post 8.

[0035] Two sealing plates 18 on the second float 2 protrude from the upper surface of the second float 2. Each shaft seat 17 of the hinged arm base 4 is connected to a corresponding sealing plate 18 by multiple fixing cross pins 19. A gap is provided between the two shaft seats 17, and each end of the connecting shaft 10 located in the gap is movably installed in the shaft seat hole of one shaft seat 17. The above structure forms a structurally reliable hinged arm base 4, which facilitates a reliable connection between the hinged arm 5 and the hinged arm base 4 through the connecting shaft 10.

[0036] The positioning pin hole 9 is a square hole, and a positioning pin 22 is inserted into the positioning pin hole 9. In the above structure, after the positioning hole of the hinge arm is inserted into the corresponding guide post, a positioning pin is inserted into the positioning pin hole to limit the vertical movement of the hinge arm and effectively prevent the hinge arm 5 from detaching from the guide post 8.

[0037] The hinged base housing 3, hinged arm base 4, centering arm 6, guide post 8, connecting shaft 10, sealing plate 18, and positioning pin 22 are all made of metal. These metal components offer high strength, long service life, reusability, and low cost.

[0038] The articulated arm 5 includes a connecting part 20 and a positioning part 21, which are T-shaped. One end of the connecting part 20 has a connecting hole 12, and each side of the positioning part 21 has a positioning hole 11. In this structure, the connecting part 20 and the positioning part 21 are an integral unit. Each articulated arm is connected to the guide post 8 via two positioning parts, improving positioning reliability.

[0039] The floating bridge connection structure described in this invention is formed by connecting multiple floating bodies. Adjacent floating bodies are connected by a movable connection structure. During connection, the first floating body 1 and the second floating body 2 are positioned close together. When connecting, the centering arm 6 at one end of the second floating body 2 extends into the centering groove 7 at one end of the first floating body 1, quickly achieving initial centering of the first floating body 1 and the second floating body 2, restricting the movement of the two floating bodies within a certain range, and facilitating the connection of the hinge arm 5. One end of the hinge arm 5 is hinged to the connecting shaft 10 on the hinge arm base 4 of the second floating body 2, allowing it to flip up and down. After the hinge arm 5 flips down, the positioning hole 11 at the other end of the hinge arm 5 can be engaged with the tapered guide post 8, achieving horizontal positioning. Then, a positioning pin 22 is inserted into the positioning pin hole 9 on the guide post 8, achieving a reliable connection between the hinge arm 5 and the guide post 8. This achieves a reliable connection between the first float 1 and the second float 2. Both are movable structures that can swing, releasing wave moments and preventing easy breakage under external impact. Hinged joints are used between the float units to ensure the structural safety of the assembled floating pier. Besides the connection structure's ability to withstand large loads, it also facilitates quick and easy assembly in waves. After initial alignment of the first float 1 and the second float 2, flipping the hinged arm 5 allows for accurate and rapid connection between the hinged arm 5 and the guide post 8, reducing construction difficulty, improving efficiency, and solving the problem of connection and assembly under floating body movement conditions in wind and waves. Furthermore, the connected structure reliably withstands huge wave moments and will not easily disintegrate.
