Technical Field
[0001] This utility model relates to the field of dock floating bridge technology, specifically a quick-assembly dock floating bridge. Background Technology
[0002] Floating bridges, as important water facilities connecting land and water, facilitating the embarkation and disembarkation of personnel, loading and unloading of cargo, and berthing of ships, are widely used in ports, inland rivers, lakes, and coastal areas. They utilize their own buoyancy (usually through sealed pontoons or floats) to rise and fall with the water level. Traditional fixed wharf structures are difficult to adapt to such large changes in water level; when the water level rises, fixed wharves may be submerged or have excessively steep slopes; when the water level drops, the wharf may be suspended in mid-air, making it impossible for personnel and vehicles to pass safely, and even causing damage to the connecting structures. To solve this problem, floating bridges have emerged.
[0003] However, existing floating bridges have the following problems in use: Most floating bridges currently rely on the buoyancy provided by the pontoons to automatically rise and fall with changes in water level, which has good adaptability. In the construction process, it is usually necessary to first splice adjacent pontoons horizontally and vertically on the water surface through special connectors to form a stable floating unit; then install the bridge deck structure (such as panels, keel or support frame) on the upper part of the spliced pontoons, and finally lay the passage moisture-proof board. This construction process of "splitting the pontoons first and then installing the bridge deck layer by layer" is relatively complicated, the on-site operation time is long, it is greatly affected by weather and water flow conditions, the overall assembly efficiency is low, and it is not conducive to rapid deployment and modular expansion. Utility Model Content
[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a rapid assembly type pontoon bridge for wharves, which realizes rapid assembly and efficient connection of pontoon bridge units.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A quick-assembly pontoon bridge includes an installation block. Floats are fixedly installed at equal intervals on the lower side of the installation block, and bridge deck panels are fixedly installed at equal intervals on the upper side of the installation block. Insert blocks are fixedly installed at equal intervals on the left sidewall of the installation block, with limit grooves provided on the insert blocks. Fixing blocks are fixedly installed at equal intervals inside the left side of the installation block, with receiving cavities adapted to the insert blocks on the fixing blocks. Through holes are provided on both sides of the receiving cavities. A locking mechanism and a pushing mechanism are provided inside the installation block.
[0007] Preferably, the locking mechanism includes a movable bar, which is slidably installed inside the mounting block. Connecting blocks are fixedly installed on the movable bar at equal intervals. Limiting rods are fixedly installed on multiple connecting blocks. The centers of the through hole, the receiving cavity, and the limiting groove are on the same straight line.
[0008] Preferably, the pushing mechanism includes an internally threaded tube, which is fixedly installed on the side wall of the mounting block. A threaded post is threadedly installed on the internally threaded tube. One end of the threaded post inside the mounting block is rotatably installed on the moving bar. A handwheel is fixedly installed on the end of the threaded post that protrudes from the mounting block.
[0009] Preferably, a waterproof sealing box is movably mounted on the mounting block, and the portion of the threaded post protruding from the mounting block, the portion of the internal threaded tube protruding from the mounting block, and the handwheel are all located inside the waterproof sealing box.
[0010] Preferably, the mounting block has a hollow interior and is fitted with intersecting reinforcing ribs at equal intervals inside.
[0011] Preferably, the mounting block located near the shore end has ear blocks fixedly installed at both ends facing the shore, and each ear block is fitted with a pull rope.
[0012] Preferably, a sealing gasket is embedded in the part of the insert block where it connects with the mounting block, and the sealing gasket is adapted to the outer end face of the fixing block.
[0013] Preferably, anti-collision strips are embedded in the side walls of the mounting block.
[0014] Preferably, it also includes a movable approach bridge, the lower end of which abuts against the upper surface of the near-shore mounting block.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This invention adopts a highly integrated modular design, enabling each module to be equipped with a pontoon, bridge deck, and standardized connection interface. This allows for unitized independent manufacturing and rapid on-site assembly, eliminating the need for traditional layer-by-layer construction and significantly improving the efficiency of pontoon bridge construction and dismantling. Key connection parts utilize a plug-in and receiving cavity cooperation structure to achieve rapid alignment between modules. Based on this, a push mechanism (handwheel + threaded transmission) drives the internal moving bar, causing multiple limit rods to simultaneously enter or exit the limit grooves on the plug-in, completing multi-point one-time locking or unlocking. This synchronous operation mechanism not only ensures connection strength and overall stability but also significantly reduces the complexity of manual operation, avoiding errors and time consumption caused by point-by-point locking. It enables rapid deployment and flexible adjustment, combining high efficiency, reliability, and maintainability. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Please see Figures 1 to 6 A quick-assembly pontoon bridge includes an installation block 2, on the lower side of the installation block 2, pontoons 3 are fixedly installed at equal intervals, and on the upper side of the installation block 2, bridge deck panels 4 are fixedly installed at equal intervals.
[0026] Each mounting block 2 is equipped with multiple buoyant pontoons 3 underneath, allowing it to float on the water surface. The top surface of the mounting block 2 is equipped with a non-slip, waterproof bridge deck 4, forming a safe walking surface. On-site, multiple mounting block 2 modules can be connected to quickly build the floating bridge platform, eliminating the need for on-site layer-by-layer assembly and greatly improving construction efficiency.
[0027] It is worth noting that bridge deck 4 needs to undergo waterproofing and anti-corrosion treatment to ensure its service life.
[0028] Insert blocks 8 are fixedly installed at equal intervals on the left side wall of mounting block 2. Limiting grooves 9 are provided on the insert blocks 8. Fixing blocks 11 are fixedly installed at equal intervals on the left side interior of mounting block 2. Receiving cavities 12 adapted to insert blocks 8 are provided on fixing blocks 11. Through holes 20 are provided on both sides of the receiving cavities 12.
[0029] When two mounting blocks 2 need to be joined laterally, the insert 8 on one mounting block 2 is inserted into the receiving cavity 12 of the adjacent mounting block 2 to achieve initial positioning and connection. The limiting groove 9 and the through hole 20 provide a channel for the locking mechanism to enter. This plug-in structure ensures that the connection between modules is firm and not easy to loosen, while maintaining a certain alignment accuracy, which is suitable for resisting lateral displacement in water surface ripple environment.
[0030] The mounting block 2 is equipped with a locking mechanism and a pushing mechanism.
[0031] The locking mechanism is responsible for securing the module firmly after the initial docking (the insert 8 is inserted into the receiving cavity 12) to prevent it from disengaging. The pushing mechanism is used to drive the locking mechanism to move (pushing the limit rod 19 into the locked position or pulling it back to the unlocked position) to achieve the opening and closing of the lock.
[0032] like Figure 5 , Figure 6 As shown, the locking mechanism includes a movable bar 17, which is slidably installed inside the mounting block 2. Connecting blocks 18 are fixedly installed on the movable bar 17 at equal intervals. Limiting rods 19 are fixedly installed on multiple connecting blocks 18. The centers of the through hole 20, the receiving cavity 12 and the limiting groove 9 are on the same straight line.
[0033] When the pushing mechanism drives the moving bar 17 to move, the connecting block 18 will drive all the limiting rods 19 on it to move synchronously. The limiting rods 19 are pushed through the through hole 20 of the fixed block 11, the limiting groove 9 of the insert 8, and the through hole 20 on the other side of the fixed block 11, so as to firmly lock the insert 8 in the receiving cavity 12 of the fixed block 11 like a pin. This can realize the synchronous operation of multiple connection points, which is convenient for installation and disassembly.
[0034] like Figure 5 , Figure 6 As shown, the pushing mechanism includes an internally threaded tube 14, which is fixedly installed on the side wall of the mounting block 2. A threaded post 15 is threadedly installed on the internally threaded tube 14. One end of the threaded post 15 inside the mounting block 2 is rotatably installed on the moving bar 17 (the specific rotation method can be the bearing rotation method, that is, an outer bearing retaining ring is fixedly connected to the moving bar 17, and an inner bearing retaining ring that cooperates with it is fixedly connected to the threaded post 15). A handwheel 16 is fixedly installed on the end of the threaded post 15 that protrudes from the mounting block 2.
[0035] The operator rotates the handwheel 16, causing the threaded column 15 to rotate in the internal threaded tube 14. Since the end of the threaded column 15 is rotatably connected to the moving bar 17, while the internal threaded tube 14 is fixed, the rotational motion of the threaded column 15 is converted into its own axial movement, thereby pushing or pulling the moving bar 17 to drive the limiting mechanism.
[0036] like Figure 2 , Figure 3 As shown, a waterproof sealing box 10 is movably mounted on the mounting block 2. The portion of the threaded post 15 protruding from the mounting block 2, the portion of the internal threaded tube 14 protruding from the mounting block 2, and the handwheel 16 are all located inside the waterproof sealing box 10.
[0037] The waterproof sealing box 10 is an openable (such as hinged or threaded disassembly) rectangular protective cover. The end face of the waterproof sealing box 10 that contacts the mounting block 2 is inlaid with a corresponding rubber strip. Since this part is prior art, it will not be described in detail here.
[0038] Its main function is to enclose and protect key operating components exposed to the humid and watery dock environment, effectively preventing seawater corrosion, salt spray, rainwater, dust and other contaminants from entering, avoiding thread corrosion and jamming, and extending the service life and reliability of the propulsion mechanism. When the locking mechanism needs to be operated, the handwheel 16 can be rotated by opening the waterproof sealing box 10.
[0039] like Figure 4 As shown, the interior of the mounting block 2 is a hollow structure, and the interior of the mounting block 2 is fixedly equipped with crisscrossing reinforcing ribs 13 at equal intervals.
[0040] The hollow structure reduces the weight of the mounting block 2, which helps to provide greater effective buoyancy. The internal crisscrossing reinforcing ribs 13 greatly enhance the overall rigidity and strength of the mounting block 2, enabling it to withstand personnel movement, equipment placement, water flow impact, wave loads, and forces transmitted at module connection points without excessive deformation or damage, thus ensuring the stability and safety of the floating bridge platform.
[0041] like Figure 1 As shown, the mounting block 2 located near the shore has ear blocks 5 fixedly installed on both ends facing the shore. Each ear block 5 is fitted with a pull rope 6, and the other end should be stably connected to the foundation.
[0042] Ear block 5 is an accessory for mooring on the near-shore mounting block 2. One end of the rope 6 (usually an anchor chain or high-strength cable) is connected to the module on the near-shore end of the floating bridge through ear block 5, and the other end is firmly fixed to the foundation on the shore (such as ground anchor, mooring pile, concrete pier). The function of the rope 6 is to limit the drift range of the entire floating bridge platform under the influence of water flow, wind and waves or ships, to roughly restrain it in the predetermined position, to keep the connection between the floating bridge and the movable approach bridge 1 on the shore aligned, and to prevent the floating bridge from being washed away.
[0043] like Figure 6 As shown, the insert block 8 has a sealing gasket 21 embedded in the part where it connects with the mounting block 2, and the sealing gasket 21 is adapted to the outer end face of the fixing block 11.
[0044] The sealing gasket 21 (usually rubber or elastic sealing material) is installed at the root of the insert 8 (i.e., the part connected to the body of the mounting block 2). When the insert 8 is fully inserted into the receiving cavity 12 of the fixing block 11, the sealing gasket 21 will be tightly pressed between the root of the insert 8 and the outer end face of the fixing block 11, forming an effective waterproof seal to prevent external water (especially wave splash) from seeping into the interior of the mounting block 2 from the gap at the module connection, protecting the internal mechanisms (such as locking mechanism, pushing mechanism, reinforcing rib 13) from corrosion and extending the structural life.
[0045] like Figure 2 As shown, anti-collision strips 7 are embedded in the side wall of mounting block 2.
[0046] The anti-collision strip 7 (usually made of elastic, wear-resistant materials such as rubber or polyurethane) is embedded in the side wall of the mounting block 2, especially at the edge of the module. Its main function is to absorb and buffer the collision energy generated when the berthing vessel or adjacent floating bridge modules (if arranged side by side) come into contact. This can effectively protect the mounting block 2 body, the pontoon 3 and the vessel itself from damage caused by hard impacts, and improve safety and durability.
[0047] like Figure 1 As shown, it also includes a movable approach bridge 1, the lower end of which abuts against the upper surface of the near-shore mounting block 2.
[0048] The entire dock floating bridge system consists of multiple modules (installation block 2 units) connected in series to form a floating platform, which is used in conjunction with the movable approach bridge 1. One end (higher end) of the movable approach bridge 1 is usually hinged to a fixed foundation on the shore, while the other end (lower end) rests on the upper surface of the installation block 2 (near shore end module) which is closer to the shore. Since the structure and specific installation of the movable approach bridge 1 are existing technologies, they will not be described in detail here.
[0049] The design of the movable approach bridge 1 allows it to rotate up and down around its hinge point on the shore as the tide rises and falls or the water level changes. Meanwhile, its lower end, which rests on the floating bridge module, always remains in contact with the floating bridge platform. In this way, the floating bridge module rises and falls with the water level through the floats 3, and the movable approach bridge 1 adapts to the water level changes by rotating. Together, they ensure that there is always a moderately sloped, continuous, and safe passageway between the shore and the floating platform.
[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
