Abstract
Description
Technical Field
[0001] This utility model relates to the field of shallow water construction technology, and in particular to a floating platform for floating transport in shallow waters. Background Technology
[0002] In shallow sea beaches, docks, or seaside viewing areas, to prevent the shoreline from being heavily eroded and washed away by seawater, precast concrete blocks or precast steel blocks are typically transported to the shallow areas requiring hardening and then placed on the seabed or riverbanks for hardening and reinforcement. Traditionally, transport ships are used for this purpose; however, due to their heavy structure, they are difficult to operate stably in shallow waters and are prone to running aground or getting stuck in the mud. If small fishing boats are used, they are flexible but lack sufficient load capacity, and the existing hull structure makes it inconvenient to accurately place the precast blocks, and the lack of supporting lifting equipment makes operation difficult. Utility Model Content
[0003] In view of the above, it is necessary for this utility model to provide a floating platform that is easy to adjust and disassemble, so as to improve the efficiency and safety of shallow water operations.
[0004] The technical solution of this utility model is as follows:
[0005] A floating platform for shallow water transport includes two boxes, two horizontal trusses, and a lifting frame. The two boxes are arranged in parallel with a gap between them. The two horizontal trusses are arranged between the two boxes and their two ends are fixedly connected to each box. The lifting frame is sandwiched between the two horizontal trusses, and its two ends are respectively mounted on top of the two boxes for suspending concrete blocks and driving the concrete blocks to be transported in the water.
[0006] Furthermore, the enclosure includes a support frame, an outer shell, and a guardrail. The support frame is a cage-shaped frame, the outer shell is wrapped around the support frame and fixedly connected to the support frame, and the guardrail is set along three perimeters on the top surface of the outer shell, wherein the side closest to the other enclosure does not have a guardrail.
[0007] Furthermore, the top surface of the outer shell is provided with raised patterns to increase surface friction and prevent slippage when there is water on the top surface of the steel plate.
[0008] Furthermore, the top surface of the outer casing is provided with at least one detection port for monitoring the sealing status inside the casing and the stored items.
[0009] Furthermore, each of the aforementioned parallel trusses is installed on one side of the box body, including two connecting rods and a reinforcing rib. The two connecting rods are stacked on top of each other and installed parallel to each other on the sides of the two boxes body. The two ends of each connecting rod are fixed to the two boxes body respectively, and the reinforcing rib is connected between the two connecting rods.
[0010] Furthermore, the hoisting frame includes a load-bearing beam, four stops, and a quick-release hook. The load-bearing beam is installed on the top surface of the outer shell, and both ends of the load-bearing beam are fixed to the two shells respectively. The four stops are all fixed on the top surface of the outer shell, with each pair of stops forming a group. Each group of stops is located on both sides of one end of the load-bearing beam to clamp the load-bearing beam. The quick-release hook is installed in the middle of the load-bearing beam for suspending concrete blocks.
[0011] Compared to existing technologies, this utility model presents a floating platform design for shallow water transport. A horizontal truss and lifting frame connect two hulls that float in the water, causing concrete blocks suspended below the load-bearing beam to move with the hulls while submerged. This allows the load-bearing beam to lift and transport concrete blocks in shallow water. Furthermore, the buoyancy of the concrete in the water reduces the load on the load-bearing beam, significantly reducing operating costs and mitigating the problem of large ships easily running aground and small ships being unable to support the load. The concrete blocks move with the floating platform and are directly deployed upon reaching the designated location, eliminating the need for lifting equipment to lift and lower the concrete blocks into the water. This saves labor costs, avoids safety hazards during lifting, and greatly ensures the safety of personnel. This utility model provides a floating platform for shallow water transport that effectively reduces operating costs, increases safety during construction operations, and improves the platform's service life and work efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0018] Please refer to Figure 1 , a floating box platform for shallow water floating transportation, comprising two boxes 1, two parallel trusses 2 and a hoisting frame 3. The two boxes 1 are arranged in parallel at intervals, and the two parallel trusses 2 are arranged between the two boxes 1, so that an installation seam is formed between the two boxes 1 to reserve a position for installing concrete blocks. The hoisting frame 3 is clamped between the two parallel trusses 2, and both ends of the hoisting frame 3 are respectively carried above the two boxes 1. The concrete block is suspended below the hoisting frame 3, so that the concrete block is transported in water. The concrete block has a certain buoyancy in water, reducing the bearing capacity on the hoisting frame 3.
[0019] As Figure 2 and Figure 3 shown, the box 1 comprises a bearing frame 11, an outer shell 12 and a guardrail frame 13. The bearing frame 11 is formed by crisscrossing metal rods or metal plates into a cage-shaped frame, and the positions where each metal rod or each metal plate intersect in the cage-shaped frame are fixed by welding. The outer shell 12 is wrapped outside the bearing frame 11 and fixedly connected to the bearing frame 11. The top surface of the outer shell 12 is made of patterned steel plate, which is used to increase the surface friction and prevent side slipping when there is water stain on the top surface of the steel plate. And a detection port 121 and a towing pile 122 are provided on the top surface of the outer shell 12. There is at least one detection port 121, which is used to monitor the sealing state inside the outer shell 12 and the stored items. There are at least two towing piles 122, which are located at one end of the top surface of the outer shell 12 far from the other box 1, and are used for tying ropes to connect with the towing boat and moving along with the towing boat. The guardrail frame 13 is arranged along three perimeters of the top surface of the outer shell 12, and the side close to the other box 1 is not provided with the guardrail frame 13 for installing the hoisting frame 3. The guardrail frame 13 is made of welded metal square tubes, and the vertical height is 1.2 meters to 1.4 meters, providing protection for the staff from falling into the water. It can be understood that when the staff hoist concrete of different weights, different weights of counterweights can be loaded into the outer shell 12 through the detection port 121 to increase the stability of the box 1 in water.
[0020] In this embodiment, the bearing frame 11 and the outer shell 12 are processed by steel plates. The structure welding of the bearing frame 11 adopts secondary welds. After the bearing frame 11 is welded, hydraulic oil or engine oil is applied to the weld positions, and the weld positions are observed every four hours, eight hours, and twelve hours to check whether there is oil leakage or oil penetration on the other side of the weld. If there is no leakage, it is qualified, and the penetrated places should be repaired by welding in time. There are two detection ports 121, which are respectively located at the diagonals of the top surface of the outer shell 12, facilitating the timely discharge of waste smoke and exhaust gas generated during welding during processing, and facilitating personnel to observe whether there is leakage in the outer shell 12 or enter the interior for maintenance during use.
[0021] As Figures 1 to 3As shown, two horizontal trusses 2 are installed on both sides of the installation joint. Each horizontal truss 2 includes two connecting rods 21 and a reinforcing rib 22. The two connecting rods 21 are stacked on top of each other and installed parallel to each other on the sides of the two boxes 1. The two ends of each connecting rod 21 are fixed to the outer shell 12 of the two boxes 1 by screwing or welding. The reinforcing rib 22 is set between the two connecting rods 21 and corresponds to the installation joint to enhance the stability of the connection between the connecting rods 21 and the outer shell 12.
[0022] The lifting frame 3 includes a load-bearing beam 31, four stops 32, and a quick-release hook 33. The load-bearing beam 31 is made of I-beam steel and is installed on the top surface of the outer shell 12. Both ends of the load-bearing beam 31 are fixed to the top surfaces of the two outer shells 12 and correspond to the centerline of each outer shell 12. This ensures that the load-bearing beam 31 distributes the weight evenly to the two boxes 1 when lifting concrete blocks, preventing uneven stress on the boxes 1 from causing them to tip over. The four stops 32 are all fixed to the top surface of the outer shell 12, with two stops 32 forming a group. Each group of stops 32 is located on both sides of one end of the load-bearing beam 31, clamping the load-bearing beam 31. The quick-release hook 33 is installed in the middle of the load-bearing beam 31 and is used to suspend the concrete block, causing the concrete block to move synchronously with the floating platform in the water.
[0023] Understandably, to enable the floating platform to transport concrete independently, jacks can be installed at positions corresponding to the top surface of the outer shell 12 and the two ends of the load-bearing beam 31. The load-bearing beam 31 is fixed to the top of the jacks. After the concrete block is hoisted, the jacks are driven to rise, causing the concrete block to rise synchronously and suspend in the water. Furthermore, a winch can be installed between the quick-release hook 33 and the load-bearing beam 31. The winch is installed on the load-bearing beam 31 and connected to the quick-release hook 33. The winch's winding and unwinding drives the quick-release hook 33 to rise and move, lifting the concrete block from the beachbed and suspending it in the water. This allows the seawater to provide buoyancy, reducing the load on the floating platform, lowering the center of gravity of the load platform, and enhancing the stability of the floating platform when transporting concrete blocks.
[0024] When transporting concrete blocks in shallow waters, the working principle of the floating platform of this utility model for floating transport in shallow waters is as follows:
[0025] The floating platform was lifted into the water as a whole using cranes and other lifting equipment on the shore, and the two boxes 1 floated on the water surface under the buoyancy of the water.
[0026] After the floating platform is launched, auxiliary lifting equipment such as truck cranes are used on the shore to lift the concrete blocks to the load-bearing beam 31 of the floating platform. The concrete blocks are equipped with cables, which are knotted and hung on the quick-release hooks 33.
[0027] After the precast concrete blocks are hoisted, check whether the concrete blocks are securely connected to the quick-release hook 33. After the check is completed, use a cable to connect the floating platform to the towing vessel. One end of the cable is tied to the towing vessel, and the other end is tied to the floating platform towing pile 122. The floating platform is then moved to the target position by the towing vessel.
[0028] After the floating platform structure pulls the precast concrete block to the target position, the locking structure of the quick-release hook 33 is pried open or pressed with a crowbar. The cable on the precast concrete block is released from the quick-release hook, and the concrete block falls to the bottom of the water under its own weight. After the concrete block falls, the diver dives to the bottom of the water to fine-tune the position of the concrete block and untie the cable on the concrete block.
[0029] After the concrete blocks are lowered, the pontoon is towed back to the shore by a tugboat to repeat the transportation and placement of the next concrete block.
[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
