Description

Technical Field

[0001] This invention relates to a sliding deployment tray, belonging to the technical field of deployment devices for marine equipment. Background Technology

[0002] The ocean contains abundant biological, mineral, and natural resources. Currently, the intensity of ocean exploration is increasing year by year, and the equipment for ocean resource detection and development is also being upgraded accordingly. These devices are becoming increasingly larger and heavier, making their deployment increasingly difficult.

[0003] Currently, the deployment methods for large marine equipment can be categorized as follows: First, deployment using semi-submersible vessels or submersible platforms; this method is expensive and slow. Second, direct deployment using shipboard cranes; this method is highly dependent on sea conditions, carries significant risks, and has low operability. Third, shipboard sliding deployment; this method requires supporting equipment and is more practical. Existing sliding deployment devices can deploy some marine equipment, but these devices use cantilever beam structures, resulting in weak load-bearing capacity. Furthermore, the same deployment device has poor adaptability to deployment equipment of varying weights and lengths. Currently, for equipment of large size and weight, even larger deployment devices and platforms are required, leading to high operating costs. Summary of the Invention

[0004] In view of this, in order to solve the technical problems of weak load-bearing capacity and inability to adapt to various sizes in the existing deployment devices, the purpose of this invention is to provide a sliding deployment tray, which has strong load-bearing capacity and is suitable for various large-size deployment equipment, especially for the deployment of rod-shaped, column-shaped, and similar rod-shaped or column-shaped surface or underwater equipment.

[0005] To achieve the objectives of this invention, the following technical solutions are provided.

[0006] A sliding deployment tray includes a first tray, a last tray, and a bottom tray. The bottom tray includes a guide rail and a plurality of rubber-coated rollers arranged longitudinally along the guide rail. The first tray and the last tray are sequentially arranged on the bottom tray along its longitudinal direction and slide in cooperation with the rubber-coated rollers. Deployment equipment is placed on the first tray and the last tray. The arrangement of the guide rail and the rubber-coated rollers allows the first tray and the last tray to slide freely on the bottom tray along its longitudinal direction. The first tray and the last tray are connected in series by a rope, the length of which allows the first tray and the last tray to slide out along the bottom tray and enter the water. The fixed end of the rope is connected to a deployment platform for easy retrieval of the first tray and the last tray after entering the water. The length of the first tray ensures that the center of gravity of the deployment equipment is located on the first tray.

[0007] Furthermore, the length of the first pallet ensures that the center of gravity of the deployment equipment is located on the first pallet. Thus, when the center of gravity of the deployment equipment slides off the bottom pallet, it ensures that the head of the first pallet and the head of the deployment equipment tilt up synchronously, ensuring that the first pallet is as close to the platform as possible, thereby protecting the deployment equipment.

[0008] Furthermore, the first tray includes a head buffer block, a flat pad, and a first support plate; the head buffer block is L-shaped with an inner arc surface; the first support plate is inverted U-shaped, including a horizontal part and downward vertical parts respectively disposed on both sides of the horizontal part; the head buffer block is bonded to one end of the upper surface of the horizontal part of the first support plate by the flat pad;

[0009] Multiple pad groups are installed along the longitudinal direction of the first support plate on the unbonded portion of the upper surface of the horizontal part of the first support plate, and each pad group includes two pads symmetrically distributed along the longitudinal centerline of the first support plate; the upper surface of the pad is an arc surface that can fit against the surface of the deployment equipment; a conduit for passing through a rope is integrally formed on the upper surface of the horizontal part of the first support plate and inside each pad, and the axial direction of the conduit is consistent with the longitudinal direction of the first support plate.

[0010] Furthermore, the tail tray includes a second support plate and a multi-segment pad assembly as needed. The second support plate is inverted U-shaped, including a horizontal portion and downward-facing vertical portions respectively disposed on both sides of the horizontal portion. The multi-segment pad assembly is installed on the upper surface of the horizontal portion of the second support plate along the longitudinal direction of the second support plate. Each pad assembly includes two pads symmetrically distributed along the longitudinal centerline of the second support plate. The upper surface of the pads is an arc surface that can fit against the surface of the deployment equipment. A guide tube for passing through a rope is integrally formed on the upper surface of the horizontal portion of the second support plate and inside each pad. The axial direction of the guide tube is consistent with the longitudinal direction of the second support plate.

[0011] The rope enters from a conduit on one side of the tail of the sliding deployment tray, passes sequentially through conduits on the same side arranged longitudinally along the second support plate and the first support plate, and then passes sequentially through the conduit on the other side from the first conduit at the head of the first support plate on the other side, and exits from the conduit on the other side of the tail of the sliding deployment tray. The two ends of the rope are fixed ends connected to the deployment platform.

[0012] Furthermore, the elastic modulus of the material constituting the flat pad is greater than the elastic modulus of the material constituting the head cushion.

[0013] Furthermore, in the first tray, the height of the upper surface of the pad is lower than the height of the upper surface of the head buffer horizontal part.

[0014] Furthermore, the installation height of the last rubber-coated roller at the end of the guide rail should be lower than the installation height of the other rubber-coated rollers.

[0015] Beneficial effects

[0016] (1) This invention provides a sliding deployment pallet, wherein the first and last pallets can slide freely along the longitudinal direction of the bottom pallet. Both pallets are submerged in water together with the deployment equipment, enabling the equipment to be deployed on a water surface platform. Compared to deployment equipment that is thrown directly from the air, the sliding deployment pallet of this invention reduces the impact on the deployment equipment. The segmented structure can be adapted to the deployment of various equipment sizes and can be reused. The sliding deployment pallet is also suitable for equipment with large size and weight. The pallet has a simple structure, is easy to load and unload, is easy to transport, has a strong load-bearing capacity, can adapt to various equipment sizes, and can be recycled.

[0017] (2) The present invention provides a sliding placement pallet, wherein the first pallet and the last pallet of the sliding placement pallet are provided with multiple segments of pad blocks, which can be adjusted according to the shape of the carrying equipment, and this segmented combination structure is convenient for transportation.

[0018] (3) The present invention provides a sliding placement tray, wherein the height of the upper surface of the pad in the first tray is lower than the height of the upper surface of the head buffer horizontal part, thereby improving the buffering capacity.

[0019] (4) The present invention provides a sliding pallet, wherein the installation height of the last rubber-coated roller at the end of the guide rail is lower than the installation height of the other rubber-coated rollers, so as to increase the load-bearing capacity of the bottom pallet when the first and last pallets are tilted upward.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1-4 As shown, a sliding deployment tray includes a first tray, a last tray, and a bottom tray. The bottom tray includes a guide rail 3 and multiple rubber-coated rollers 4 arranged longitudinally along the guide rail 3. The first and last trays are sequentially arranged on the bottom tray along its longitudinal direction and slide in cooperation with the rubber-coated rollers 4. The guide rail 3 and the rubber-coated rollers 4 allow the first and last trays to slide freely on the bottom tray along its longitudinal direction. The first and last trays are connected in series by a rope 5. The length of the rope 5 allows the first and last trays to slide out of the bottom tray and into the water. The fixed end of the rope 5 is connected to the deployment platform for easy retrieval of the first and last trays after they enter the water. The length of the first tray ensures that the center of gravity of the deployment equipment is located on the first tray.

[0029] The first tray includes a head buffer block 1, a flat pad 6, and a first support plate 8. The head buffer block 1 is L-shaped with an inner arc surface (i.e., the inner side of the vertical part of the head buffer block 1 is an arc surface). The length of the flat pad 6 is the same as the length of the horizontal part of the head buffer block 1, and the length of the first support plate 8 is greater than the length of the flat pad 6. The first support plate 8 is inverted U-shaped, including a horizontal part and downward vertical parts respectively disposed on both sides of the horizontal part. The outer side of the horizontal part of the head buffer block 1 is bonded to one side of the flat pad 6, and the other side of the flat pad 6 is bonded to one side of the upper surface of the horizontal part of the first support plate 8. The head buffer block 1 is attached to one end of the horizontal upper surface of the first support plate 8 by a flat pad 6; the part of the horizontal upper surface of the first support plate 8 where the flat pad 6 is not attached is connected to a multi-segment pad group as needed by screws along the longitudinal direction of the first support plate, each segment pad group including two pads 2 symmetrically distributed along the longitudinal center line of the first support plate 8; the upper surface of the pad 2 is an arc surface that can fit against the surface of the deployment device 10; a conduit 7 for the rope 5 to pass through is welded on the upper surface of the horizontal part of the first support plate 8 and inside each pad 2, the axial direction of the conduit 7 being consistent with the longitudinal direction of the first support plate 8.

[0030] The head buffer block 1 is made of high-density EPE pearl cotton (also known as polyethylene foam), which allows for rapid processing according to different sizes of the placement equipment 10 and has strong adaptability.

[0031] The material constituting the flat pad 6 is rubber, and the elastic modulus of the rubber is greater than that of high-density EPE pearl cotton.

[0032] In the first tray, the height of the upper surface of the pad 2 is lower than the height of the upper surface of the horizontal part of the head buffer block 1, thereby improving the buffering capacity.

[0033] The tail tray includes a second support plate 9 and a multi-segment pad assembly as needed. The second support plate 9 is inverted U-shaped, including a horizontal part and downward vertical parts respectively disposed on both sides of the horizontal part. The upper surface of the horizontal part of the second support plate 9 is connected to the multi-segment pad assembly as needed along the longitudinal direction of the second support plate 9 by screws. Each pad assembly includes two pads 2 symmetrically distributed along the longitudinal centerline of the second support plate 9. The upper surface of the pad 2 is an arc surface that can fit against the surface of the deployment device 10. A conduit 7 for passing through the rope 5 is welded on the upper surface of the horizontal part of the second support plate 9 and inside each pad 2. The axial direction of the conduit 7 is consistent with the longitudinal direction of the second support plate 9.

[0034] The rope 5 enters from the conduit 7 on one side of the tail of the sliding deployment tray, passes through the conduits 7 arranged longitudinally along the second support plate 9 and the first support plate 8 on the same side, and then passes through the first conduit 7 at the head of the first support plate 8 on the other side, and exits from the conduit 7 on the other side of the tail of the sliding deployment tray, thus connecting the first tray and the tail tray in series. The two ends of the rope 5 are fixed ends connected to the deployment platform.

[0035] The installation height of the last rubber-coated roller 4 at the tail of the guide rail 3 should be lower than the installation height of the other rubber-coated rollers 4, in order to increase the load-bearing capacity of the bottom pallet when the first and last pallets are tilted.

[0036] The pads 2 installed on the first and last pallets form an arc surface that fits the equipment 10, reducing the surface stress on the equipment. The segmented pads 2 can be disassembled according to the position of the slings, which facilitates the hoisting of the equipment.

[0037] The assembly process of the sliding placement tray is as follows:

[0038] Step 1: First pallet installation. Weld conduit 7 to the upper surface of the horizontal part of the first support plate 8. According to the shape of the placement equipment 10, process the arc surfaces of the head buffer block 1 and the pad block 2. Lay a flat pad 6 between the head buffer block 1 and the first support plate 8, and connect the three with adhesive. The pad block 2 is fixedly connected to the upper surface of the horizontal part of the first support plate 8 that is not covered by the head buffer block 1 by screws.

[0039] Step 2: Tail tray installation. Weld conduit 7 to the upper surface of the horizontal part of the second support plate 9. Process the arc surface of pad 2 according to the shape of the deployment equipment 10. Use screws to install pad 2 to the upper surface of the horizontal part of the second support plate 9. Pad 2 is not installed at the lifting point of the deployment equipment 10.

[0040] Step 3: Install the bottom tray. Install the guide rail 3 onto the placement platform, and then install the rubber-coated roller 4 onto the guide rail 3 and tighten it with nuts.

[0041] Step 4: According to the length of the deployment equipment 10, place the first pallet and the last pallet on the bottom pallet in sequence along the longitudinal direction of the bottom pallet, then hoist the deployment equipment 10 onto the first pallet and the last pallet, and fix the head of the deployment equipment 10 to the deployment platform.

[0042] The working process of the sliding deployment tray is as follows:

[0043] The application scenarios of the sliding deployment tray are as follows: Figure 5 As shown, a bottom tray is fixed on the deployment platform, and a head tray and a tail tray are longitudinally connected on the bottom tray. The head tray and tail tray are connected in series using rope 5, with sufficient length allowance so that the deployment device 10 can slide into the water along with the head tray and tail tray. Rope 5 is connected to the deployment platform so that the head tray and tail tray can be retrieved after deployment. Then, the deployment device 10 is placed on the head tray and tail tray. In the designated deployment area, the head of the deployment platform is raised at a certain angle, releasing the deployment device 10. At this time, under the action of gravity, the deployment device 10, along with the head tray and tail tray, slides into the water simultaneously along the guide rail 3. After deployment, the head tray and tail tray are retrieved using the traction rope 5. Details are as follows:

[0044] Before deployment, the bottom tray is welded and fixed to the water surface deployment platform. The first and last trays are placed sequentially on the bottom tray along its longitudinal direction. The deployment device 10 is placed on the first and last trays, and then the head of the deployment device 10 is locked to the deployment platform to prevent longitudinal movement. The head of the bottom tray is then raised to a certain height by the lifting bracket 11. Due to friction, the first and last trays and the deployment device 10 remain relatively stationary. The arc surface formed by the pads 2 on the first and last trays fits against the surface of the deployment device 10 to prevent it from rolling.

[0045] The water surface deployment platform raises the head of the bottom tray to a certain height through the lifting bracket 11. The deployment equipment 10 will tilt at a certain angle and be released. Due to the gravity of the deployment equipment 10, the deployment equipment 10 tends to move downwards. Under the action of friction, the deployment equipment 10, the first tray and the tail tray move synchronously towards the water surface.

[0046] When the center of gravity of the deployment equipment 10 slides out of the guide rail 3, the tilt angle of the deployment equipment 10 will further increase due to gravity. Under the gravity of the deployment equipment 10, the tilt angle of the first pallet will also increase, causing the first pallet to be pressed down by the deployment equipment 10 and no longer in contact with the bottom pallet. During this process, the first and last pallets are only supported by the rubber-coated rollers 4 at the tail end of the bottom pallet, which will generate great stress. The steel structure of the first pallet can distribute this stress evenly on the deployment equipment 10, thereby protecting the deployment equipment 10.

[0047] When the head buffer block 1 of the first pallet begins to deviate from the bottom pallet, the first pallet, being a cantilever beam structure, bends under its own weight. At this time, the head buffer block 1 can prevent the first pallet from impacting the deployment equipment 10 during the descent. The first and tail pallets will separate from the deployment equipment 10 after entering the water. After deployment, the first and tail pallets are lifted using ropes 5, enabling the first and tail pallets to be reused.

[0048] This invention includes, but is not limited to, the above embodiments. Any equivalent substitutions or partial improvements made under the spirit and principles of this invention shall be considered within the scope of protection of this invention.
