Description

Technical Field

[0001] This invention belongs to the field of floating bridge technology, and more specifically, it relates to an auxiliary assembly system for floating bridge floating body units. This invention also relates to an auxiliary assembly method for floating bridge floating body units. Background Technology

[0002] Floating units can operate in shallow near-shore waters, used for assembling floating piers and winch tugboats, constructing pier wharves, and implementing shore-to-shore unloading; they can also be used for assembling pier ferries, constructing transshipment systems, and implementing transshipment and unloading. Floating units are assembled from floating modules, based on standard units, and can be expanded into propeller units, jet pump units, and seaward units. The floating modules of a floating unit are rigidly connected, forming an integral rigid structure. The form can be changed between units by replacing some modules. The assembly of floating modules into floating units takes place in sheltered waters, less affected by currents and waves. The assembly of floating units into floating piers or wharves takes place in open near-shore waters, and is therefore greatly affected by crosscurrents and waves. Assembly operations are difficult to perform manually, time-consuming, and risky.

[0003] The shortcomings of existing technology are as follows: In calm sea conditions, assembly can be completed entirely manually. After the docking units are in place, two teams of workers use cables to pull the two docking units together. However, under the influence of sea winds and currents, it is usually difficult to align and bring the two docking surfaces close together in one go. In sea state 3, precise alignment of the two units is very difficult, requiring multiple attempts to succeed. In rough sea conditions, connection may not be successful at all.

[0004] Existing technology includes a technology titled "Multi-purpose Marine Floating Box" with publication number "CN201143983Y". This technology relates to a multi-purpose marine floating box, comprising floating box modules with a skeleton-type fully welded steel structure. The features are: the floating box modules are divided into square modules, bow and stern modules, ramp modules, propulsion modules, and power supply modules. The floating box modules are spliced ​​together by rigid joints and hinged joints fixed to their sides and ends. The inner wall of the floating box at the location of the rigid or hinged joints is provided with a locally reinforced frame. Beneficial effects: Modular floating boxes of standard container dimensions facilitate maritime transportation and can be transported using container handling machinery; floating box modules can be assembled into various shallow-water floating structures as needed, such as floating docks, floating bridges, piers, large work platforms, and cargo ferries; the floating boxes have a small draft and strong environmental adaptability; the joint types are diverse, allowing for fast assembly and disassembly, easy deployment and retrieval in wind and waves, and safe and reliable connections; the assembled floating structures have good overall integrity, strong wind and wave resistance, and high load-bearing capacity. This technology does not address the technical issues or solutions of this application. Summary of the Invention

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

[0007] This invention relates to an auxiliary assembly system for floating bridge units, comprising a dynamic positioning control system and an assembly winch system. The dynamic positioning control system includes a combined control handle and multiple sets of rudder propeller propulsion chambers.

The electric winch includes a winch disc, a winch body, a winch base, and a transition base. One end of the traction rigging is wound on the winch disc, and the other end of the traction rigging is connected to the rigging connection position of another floating unit.

[0008] The floating bridge floating unit auxiliary assembly system also includes a centering system, which includes a centering groove and a centering arm. The centering groove is provided at one end of the floating unit, and the centering arm is provided at the other end of the floating unit.

[0009] The electric winch also includes a cable guide structure, with a cable guide structure provided on each side of the front of the floating unit, an electric winch provided on each side of the middle of the floating unit, and a rigging connection position provided on each side of the rear of the floating unit.

[0010] A winch motor is fixedly installed on the winch body, the winch disc is fixedly connected to the winch motor, the winch body is fixedly connected to the winch base, the winch base is connected to the transition base by bolts, and the transition base is fixedly connected to the floating unit.

[0011] The combined control handle is configured to control each propeller propulsion compartment to drive the floating body unit in different directions; the combined control handle is configured to control the floating body unit to achieve automatic heading, positioning and holding, positioning and bow turning, bow holding and shifting, heading holding and track holding functions.

[0012] The rigging connection position on the winch of the electric winch on one side of the floating body unit is configured to bypass a cable guide structure on the same side and then connect to the rigging connection position on the other side of another floating body unit.

[0013] The floating bridge floating unit auxiliary assembly system also includes a hinge system, which includes a hinge arm, a guide post, and a cross pin. One end of the floating unit is connected to the hinge arm, and the other end of the floating unit is provided with a guide post.

[0014] The cable guide structure is a roller, and the traction rigging is a high-strength fiber cable.

[0015] This invention also relates to a simple method for automatically and accurately aligning and assembling floating units in windy and wave environments, reducing manual operation, ensuring personnel safety, greatly shortening assembly time, improving assembly efficiency, enhancing adaptability to sea conditions, expanding equipment application scenarios, and providing significant benefits for the auxiliary assembly of floating units for floating piers.

[0016] The assembly steps of the auxiliary assembly method for the floating unit of the floating pier are as follows:

[0017] S1. One floating unit is positioned at a certain location in the open sea using the positioning and holding function, while the other floating unit gradually approaches using the joint manual control mode. When the two floating units approach each other, the towing rigging is thrown out, the two floating units are cross-tied, and the assembly winch system is used to wind up the towing rigging, allowing the two floating units to approach each other.

[0018] S2. When the two floating units continue to approach each other, the centering system centers the two floating units, and the assembly winch system pulls the two floating units together so that they cannot separate temporarily.

[0019] S3. When the two float units are fully brought together, flip the hinge arm of one float unit and insert it into the guide post of the other float unit. Insert the cross pin into the cross pin hole on the guide post to fix the hinge arm. The two float units are then joined together.

[0020] When the other floating body unit gradually approaches using a combined manual control mode, the dynamic positioning control system controls the floating body unit's automatic heading, positioning hold, positioning bow turn, bow hold shift, heading hold, and track hold. The steady-state control indicators achieve a position accuracy of 2m and a heading accuracy of 1.5°, realizing precise movement and positioning control of the floating body unit.

[0022] The floating bridge floating unit auxiliary assembly system of this invention improves the structure of each floating unit during structural design, and each floating unit is equipped with a dynamic positioning control system and an assembly winch system. The dynamic positioning control system controls multiple sets of rudder propeller propulsion chambers 2 through a joint control handle 1. The rudder propeller propulsion chambers 2 apply power and can control the automatic heading, positioning and holding, positioning and bow turning, bow holding and shifting, heading and track holding of the floating unit 3. The steady-state control indicators achieve a position accuracy of 2m and a heading accuracy of 1.5°, realizing the precise movement of adjacent floating units 3. The assembly winch system is used to bring two floating units 3 closer together. During the approach control, the rigging connection position 7 on the winch 8 of the electric winch 5 on one side of the floating unit 3 bypasses a guide cable structure 14 on the same side and then connects to the rigging connection position 7 on the other side of the other floating unit 3. The two traction cables 6 are arranged in a crisscross pattern. When the winch 8 of the electric winch 5 winds up the traction cables 6, the two traction cables 6 apply force from both sides, bringing the two adjacent floating units 3 closer together. After the two floating units 3 are close together, they are fixedly connected by a hinge system. In this way, the entire splicing process is convenient and efficient, reducing the manual labor intensity of the operators, and enabling precise and quick splicing operations even on sea surfaces with large waves.

[0031] 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:

[0032] As attached Figure 1 - Appendix Figure 6As shown, this invention is an auxiliary assembly system for floating bridge units, including a dynamic positioning control system and an assembly winch system. The dynamic positioning control system includes a joint control handle 1 and multiple sets of propeller propulsion chambers 2. Each side of the rear of the floating unit 3 is equipped with a propeller propulsion chamber 2, and one side of the front of the floating unit 3 is also equipped with a propeller propulsion chamber 2. The assembly winch system includes an electric winch 5 and a traction rigging 6. Each side of the floating unit 3 is equipped with an electric winch 5, and each side of the other end of the floating unit 3 is equipped with a rigging connection position 7. The electric winch 5 includes a winch disc 8, a winch body 9, a winch base 10, and a transition base 11. One end of the traction rigging 6 is wound on the winch disc 8, and the other end of the traction rigging 6 is connected to the rigging connection position 7 of another floating unit 3. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. When constructing a floating bridge on the sea, multiple floating units need to be assembled together. However, the harsh environment at sea makes the assembly of floating units quite difficult. Therefore, the structure of each floating body unit was improved during the structural design, and each floating body unit was equipped with a dynamic positioning control system and an assembly winch system. The dynamic positioning control system controls multiple sets of rudder propeller propulsion chambers 2 through a joint control handle 1. The rudder propeller propulsion chambers 2 apply power and can control the automatic heading, positioning and holding, positioning and bow turning, bow holding and shifting, heading holding, and track heading holding of the floating body unit 3. The steady-state control indicators achieve a position accuracy of 2m and a heading accuracy of 1.5°, realizing the precise movement of adjacent floating body units 3. The assembly winch system is used to bring two floating body units 3 closer together. During the approach control, the rigging connection position 7 on the winch 8 of the electric winch 5 on one side of the floating body unit 3 bypasses a guide cable structure 14 on the same side and then connects to the rigging connection position 7 on the other side of the other floating body unit 3. The two traction cables 6 are arranged in a crisscross pattern. When the winch 8 of the electric winch 5 winds up the traction cables 6, the two traction cables 6 apply force from both sides, bringing the two adjacent floating units 3 closer together. After the two floating units 3 are close together, they are fixedly connected by a hinge system. This makes the entire assembly process convenient and efficient, reducing the manual labor intensity of operators. Even in rough seas, assembly operations can be carried out accurately and quickly. The floating bridge floating unit auxiliary assembly system described in this invention has a simple structure and can automatically and accurately align and assemble floating units in rough seas, reducing manual operation, ensuring personnel safety, shortening assembly time, improving assembly efficiency, enhancing adaptability to sea conditions, expanding equipment application scenarios, and demonstrating significant benefits.

[0033] The floating bridge's auxiliary assembly system for floating body units also includes a centering system. This system comprises a centering groove 12 and a centering arm 13. The centering groove 12 is located at one end of the floating body unit 3, and the centering arm 13 is located at the other end. In this structure, after two floating body units approach a certain distance, the centering groove 12 and the centering arm 13 continuously move closer, causing the centering arm 13 to insert into the centering groove 12. This achieves relative positioning of the two floating body units 3, ensuring reliable centering. Consequently, after the two floating body units 3 approach each other, they are in a straight line, resulting in accurate and reliable positioning.

[0034] The electric winch 5 also includes a cable guide structure 14. A cable guide structure 14 is provided on each side of the front of the floating unit 3, an electric winch 5 is provided on each side of the middle of the floating unit 3, and a rigging connection position 7 is provided on each side of the rear of the floating unit 3. A winch motor is fixedly mounted on the winch body 9, and the winch disc 8 is fixedly connected to the winch motor. The winch body 9 is fixedly connected to the winch base 10, and the winch base 10 is bolted to a transition base 11, which is fixedly connected to the floating unit 3. In this structure, the transition base 11 is fixedly connected to the floating unit 3 and serves as a fastener. The connection between the transition base 11 and the winch base 10 facilitates the connection and disassembly of the electric winch and the transition base, allowing the electric winch to be used in various situations. When assembling two floating units 3, one floating unit 3 is positioned at a certain location in the open sea using the positioning and holding function, while the other floating unit 3 gradually approaches using a joint manual control mode. When the two floating units 3 approach each other, the traction cable 6 is thrown out, and the two floating units 3 are cross-attached to the cable connection position 7 of the other floating unit. The winch of the assembly winch system winds up the traction cable 6, thereby applying cross force and controlling the two floating units 3 to approach each other.

[0035] The combined control handle 1 is configured to control each propeller propulsion chamber 2 to drive the float unit 3 in different directions; the combined control handle 1 is also configured to control the float unit to perform automatic heading, positioning and holding, positioning and turning, bow holding and shifting, heading holding, and track holding functions. In this structure, propeller propulsion chambers 2 are respectively installed on each side of the rear of the float unit 3, and on one side of the front of the float unit 3. Thus, propeller propulsion chambers 2 are installed in different locations, and multiple propeller propulsion chambers 2 are controlled by the combined control handle 1, thereby achieving functions such as automatic heading, positioning and holding, positioning and turning, bow holding and shifting, heading holding, and track holding. This allows for precise control of two float units to approach each other.

[0036] The cable connection position 7 on the winch 8 of the electric winch 5 on one side of the floating body unit 3 is configured to bypass a cable guide structure 14 on the same side and then connect to the cable connection position 7 on the other side of another floating body unit 3. In this structure, one end of the two traction cables 6 is connected to one floating body unit, and the other end of the two traction cables 6 is connected to the other floating body unit. The two traction cables 6 are arranged in a crisscross pattern, thereby reliably achieving the traction and approach of the floating body units.

[0037] The floating bridge's auxiliary assembly system for floating body units also includes a hinge system. This hinge system comprises a hinge arm 15, a guide post 16, and a cross pin 17. One end of the floating body unit 3 is connected to the hinge arm 15, and the other end is equipped with the guide post 16. With this structure, when two floating body units 3 are brought close together, they are fixedly connected via the hinge arm and guide post of the hinge system. This makes the entire assembly process convenient and efficient, reducing the manual labor intensity of operators.

[0038] The cable guide structure 14 consists of rollers, and the traction rigging 6 is a high-strength fiber cable. In this structure, the rollers ensure unobstructed tightening of the traction cable; the material of the traction rigging 6 provides high strength and a long service life.

[0039] This invention also relates to a simple method for automatically and accurately aligning and assembling floating units in windy and wave environments, reducing manual operation, ensuring personnel safety, greatly shortening assembly time, improving assembly efficiency, enhancing adaptability to sea conditions, expanding equipment application scenarios, and providing significant benefits for the auxiliary assembly of floating units for floating piers.

[0040] The assembly steps of the auxiliary assembly method for the floating unit of the floating pier are as follows:

[0041] S1. One floating unit 3 is positioned at a certain location in open sea using the positioning and holding function. The other floating unit 3 gradually approaches using the joint manual control mode. When the two floating units 3 approach each other, the towing rigging 6 is thrown out. The two floating units 3 are cross-tied, and the assembly winch system winds up the towing rigging 6, bringing the two floating units 3 closer together. S2. As the two floating units 3 continue to approach each other, the centering system centers the two floating units 3, and the assembly winch system pulls the two floating units 3 together to prevent them from separating temporarily. S3. When the two floating units 3 are fully pulled together, the hinge arm 15 of one floating unit 3 is flipped over. The hinge arm 15 is fitted into the guide post 16 of the other floating unit 3, and the horizontal pin 17 is inserted into the horizontal pin hole on the guide post 16 to fix the hinge arm 15. The two floating units 3 are then assembled. When the other floating body unit 3 gradually approaches using the combined manual control mode, the dynamic positioning control system controls the floating body unit 3's automatic heading, positioning hold, positioning bow turn, bow hold shift, heading hold, and track hold. The steady-state control indicators achieve a position accuracy of 2m and a heading accuracy of 1.5°, realizing precise movement and positioning control of the floating body unit 3.

[0042] The floating bridge floating unit auxiliary assembly system of this invention includes a dynamic positioning control system, an assembly winch system, and an alignment system. An embodiment of the assembly system is described below:

[0043] 1. Dynamic Positioning Control System: The dynamic positioning control system enables automatic heading, positioning and holding, heading and turning, bow shifting, heading and course holding for the float unit assembly. Steady-state control indicators achieve a position accuracy of 2m and a heading accuracy of 1.5°. In addition to automatic positioning, it also enables semi-autonomous manual control, allowing operation of three propeller propulsion pods using a single control handle. Operation is very convenient, and the dynamic positioning control system significantly improves navigation control accuracy and operational efficiency. Dead Alignment Mode: The dynamic positioning equipment enables automatic control of the float unit assembly's position and heading, stabilizing the float unit's position at a set location and its heading at a set angle. The set position or heading can also be changed via a manual control terminal. When installing float units, the operation mode switches to "semi-autonomous manual control," allowing manual control of the float unit in three dimensions—longitudinal, lateral, and heading—using a joystick. The thrust (or torque) commands in these three dimensions are proportional to the joystick's displacement. This mode enables joint control of multiple thrusters within the floating unit group, coordinating the control of multiple thrusters to meet the three-dimensional thrust (or torque) requirements. 2. Assembled Winch System: The assembled winch system includes an electric winch, a guide cable structure, and traction rigging. The electric assembled winch includes a winch disc, winch body, winch base, and transition base. Except for the transition base, which is welded to the floating box deck, the other components can be removed when not in use. The guide cable structure consists of rollers installed on the upper surface of the bollards on both sides of the floating unit to ensure unobstructed tightening of the traction cable. The traction cable is made of high-strength fiber cable for easy and flexible operation. 3. Centering System: The centering arm is a box-shaped structure made of steel and is installed in the middle of the bow end of the floating unit. The centering groove, as the main limiting structure, is located at the stern end of the floating unit. The centering arm and centering groove work together to limit the relative movement position of the floating unit within a precise range. When using the floating bridge floating unit auxiliary assembly system described in this invention, one floating unit is positioned at a specific location in open sea using the 'positioning and holding' function, while the other floating unit gradually approaches using a combined manual control mode. When the distance between the units is 3-4 meters, the towing rigging 6 (towing cable) is deployed for cross-mooring, and the two floating units are basically aligned and brought closer together using the assembly winch. When the distance between the two floating units is close to 1 meter, the centering arm is used for precise alignment of the two floating units, and the assembly winch pulls the two floating units together to prevent them from separating temporarily. When the two floating units are fully pulled together, the hinge arm is flipped, and the hinge arm automatically fits into the guide post. The horizontal pin is inserted into the horizontal pin hole of the guide post to fix the hinge arm. The floating unit assembly is then complete.

[0044] The floating pier auxiliary assembly system of this invention provides a technical solution for building floating piers on the sea. In terms of structural design, the structure of each floating pier unit is improved, and each floating pier unit is equipped with a dynamic positioning control system and an assembly winch system. The dynamic positioning control system controls multiple sets of propeller propulsion chambers 2 via a joint control handle 1. The propeller propulsion chambers 2 apply power and can control the automatic heading, positioning and holding, positioning and bow turning, bow holding and shifting, heading holding, and track holding of the floating pier unit 3. The steady-state control indicators achieve a position accuracy of 2m and a heading accuracy of 1.5°, enabling precise movement of adjacent floating pier units 3. The assembly winch system is used to bring two floating pier units 3 closer together. During approach control, the rigging connection position 7 on the winch 8 of the electric winch 5 on one side of the floating pier unit 3 bypasses a guide cable structure 14 on the same side and then connects to the rigging connection position 7 on the other side of the other floating pier unit 3. The two traction cables 6 are arranged in a crisscross pattern. When the winch 8 of the electric winch 5 winds up the traction cables 6, the two traction cables 6 apply force from both sides, bringing the two adjacent floating units 3 closer together. After the two floating units 3 are close together, they are fixedly connected by a hinge system. In this way, the entire splicing process is convenient and efficient, reducing the manual labor intensity of the operators, and enabling precise and quick splicing operations even on sea surfaces with large waves.
