[0002] During ship operation, replenishment is a crucial aspect of a vessel's self-sufficiency. While replenishing fuel and water is relatively simple, replenishing supplies such as fruits, vegetables, rice, oil, poultry, fish, and meat is characterized by its large quantity, scattered distribution, and disorganized nature, often requiring the entire crew to move supplies back and forth using the ramps. Currently, it typically takes about 3 hours for the entire crew to move supplies back and forth using a single 3.5T pickup truck, resulting in high labor intensity, long processing time, and low replenishment efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a supply material transportation and transfer tool to solve the problems of high intensity, long time and low supply efficiency of manual handling of ship supply materials in the prior art.

[0026] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0027] A preferred embodiment of the supply material transportation and transfer tooling of the present invention, such as... Figures 1 to 6 As shown, the supply material transportation and transfer equipment includes a support frame 1, a bracket 2, a pallet 3, and a picking device. The support frame 1 is used to support the material between the ground and the ship hull, forming a path for material transportation. The bracket 2 is movably arranged on the support frame 1 and is used to transfer materials between the ground and the ship hull. The pallet 3 is used to load materials. The picking device is used to transfer the pallet 3 carrying materials to the cold storage of the ship hull.

[0028] The bottom of the support frame 1 is used to support the ground, and the top of the support frame 1 is provided with a hook 11, which is used to hook and connect with the hull, so that the support frame 1 is connected between the ground and the hull, forming a path for material transportation, replacing the existing inclined ladder for crew members to carry materials on and off the ship, thereby improving transportation efficiency and reducing the labor intensity of crew members.

[0029] The support frame 1 is equipped with guide rails that extend from the top to the bottom of the support frame 1. The guide rails guide the assembly of the bracket 2 and serve as the movement path for the bracket 2. This not only limits the movement direction of the bracket 2 but also reduces the movement resistance of the bracket 2, thereby improving resupply efficiency. In this embodiment, there are two sets of guide rails. The hooks 11 of the support frame 1 are arranged at the ends of the two sets of guide rails, so that the force exerted by the bracket 2 on the support frame 1 is on the same plane as the hooks 11. The force is transmitted to the hull through the hooks 11, preventing the support frame 1 from capsizing.

[0030] The bracket 2 is mounted on the support frame 1, and during its movement, it can transport materials from the ground to the hull. The bracket 2 is equipped with four rollers 21, which are guided by guide rails. These rollers form two rows and can roll on two sets of guide rails. The bracket 2 moves on the guide rails of the support frame 1 via the rollers 21. The rolling friction between the bracket 2 and the support frame 1 during movement reduces the resistance to movement.

[0031] A drive structure 7 is also installed between the support frame 1 and the bracket 2. The drive structure 7 is used to drive the bracket 2 to move along the guide rail, providing power for the movement of the bracket 2. The drive structure 7 can reduce the need for manpower, realize the automatic movement of the bracket 2, and improve the supply efficiency.

[0032] The pallet 3 is supported on the bracket 2. The pallet 3 is used to load materials. After being placed on the bracket 2, the pallet 3 can move synchronously with the bracket 2, thereby realizing the movement of materials. The bracket 2 is also equipped with a limiting structure to limit the movement of the pallet 3. After the hook 11 of the support frame 1 is hooked on the hull, the whole structure is arranged at an angle. When the pallet 3 moves on the guide rail via the roller 21, it moves at an angle. The limiting structure can support and limit the movement of the pallet 3 to prevent the pallet 3 from slipping or overturning on the bracket 2.

[0033] The handling device includes a transfer frame 4, a lifting frame 5, and casters 42. The transfer frame 4 supports and arranges the pallets 3. Multiple casters 42 are located at the bottom of the transfer frame 4, reducing movement resistance when the transfer frame 4 moves the pallets 3. The lifting frame 5 is used to lift the pallets 3, separating stacked pallets 3 for crew handling. A lifting mechanism 6 is also installed between the transfer frame 4 and the lifting frame 5, driving the lifting frame 5 to move the pallets 3 up and down.

[0034] The pallet 3 of this supply material transport and transfer tool can be loaded with materials to be transported and then placed on the bracket 2. The limiting structure on the bracket 2 limits the pallet 3 to prevent it from shaking when the bracket 2 moves. The bracket 2 is rolled on the guide rail of the support frame 1 via rollers 21. When the bracket 2 moves on the support frame 1, it can drive the pallet 3 to move synchronously. When loading materials, the hook 11 of the support frame 1 is hooked onto the hull. The bottom end of the support frame 1 is supported on the ground. The bracket 2 drives the pallet 3 to be transported from the bottom end to the top end of the support frame 1 along the guide rail, thereby transporting the materials to the ship and realizing automatic material handling. There is no need for personnel to carry materials up and down the ship's inclined ladder, thus reducing the manpower required for supply. After the pallet 3 is moved to the hull, personnel can load the pallet 3 onto the transfer frame 4 of the retrieval device and stack them. By pushing the transfer frame 4, the materials can be transferred to the cold storage. The lifting mechanism 6 lifts the stacked pallets 3, and the operator can move the pallets 3, improving the retrieval efficiency, reducing the time and intensity of manual handling, and improving the supply efficiency.

[0035] Preferably, the support frame 1 includes telescopic diagonal rods 12 arranged in parallel to each other and sleeve rods 13 connected between the telescopic diagonal rods 12. Hooks 11 are assembled at one end of the telescopic diagonal rods 12, and the telescopic diagonal rods 12 form guide rails.

[0036] The support frame 1 is formed by connecting telescopic diagonal rods 12 and sleeve rods 13. The telescopic diagonal rods 12 and sleeve rods 13 form a rectangular frame structure that is perpendicular to each other. The telescopic diagonal rods 12 form a guide rail, which makes the support frame 1 more integrated and simplifies its structure. The length of the telescopic diagonal rods 12 is adjustable, and its length can be adjusted according to the distance of the hull from the shore, the height of the hull, etc., making it suitable for use in different situations.

[0037] In this embodiment, the telescopic diagonal rod 12 is formed by nesting and connecting steel pipes with outer diameters of 35mm, inner diameters of 30mm and lengths of 1500mm, outer diameters of 30mm and inner diameters of 25mm and lengths of 1500mm, and outer diameters of 25mm and inner diameters of 20mm and lengths of 1500mm. That is, the telescopic rod achieves telescopic movement by using a structure where a thicker pipe encloses a thinner pipe. Adjacent thicker and thinner pipes are connected by pipe clamps. After the length of the telescopic diagonal rod 12 meets the requirements, it can be clamped and fixed with pipe clamps. The specific details are existing technology and will not be described in detail here. In this embodiment, a semi-circular bend with a diameter of 100mm is provided at the end of the telescopic diagonal rod 12, forming a hook 11.

[0038] The sleeve rod 13 is formed by connecting steel pipes with an outer diameter of 20mm, an inner diameter of 16mm, and a length of 400mm. Both ends of the sleeve rod 13 are connected to sleeves, which are fitted onto the outside of the telescopic diagonal rod 12 to fix the sleeve rod 13 to the telescopic diagonal rod 12. The connection structure between the sleeves and the telescopic diagonal rod 12 is existing technology and will not be described in detail here. There are two sets of sleeve rods 13, which are respectively arranged at both ends of the support frame 1. The two sets of sleeve rods 13 are parallel to each other to ensure that the distance between them is the same, so that the telescopic diagonal rods 12 are parallel to each other, ensuring that the bracket 2 rolls along the telescopic diagonal rods 12.

[0039] Preferably, the end of the telescopic diagonal bar 12 away from the hook 11 is fitted with a rubber sleeve 14.

[0040] The end of the telescopic diagonal bar 12 away from the hook 11 is used for inclined support on the ground. The rubber sleeve 14 can increase the friction between the bottom of the telescopic diagonal bar 12 and the ground, thereby preventing the telescopic diagonal bar 12 from slipping.

[0041] Preferably, the bracket 2 includes a crossbar 22 and a longitudinal bar 23, which are arranged in a grid pattern. Both ends of the crossbar 22 are connected to U-shaped mounting seats 24, and the rollers 21 are mounted on the mounting seats 24. The limiting structure includes a limiting rod 25, which is arranged at both ends of the longitudinal bar 23. The limiting rod 25 and the mounting seat 24 form an arrangement space for arranging the tray 3.

[0042] The bracket 2 is formed by the cross-connection of horizontal bars 22 and vertical bars 23 to form a grid-like structure, which ensures the structural strength of the bracket 2, forms a plane to support the pallet 3, and increases the stability of the pallet 3. In this embodiment, the horizontal bars 22 and vertical bars 23 are formed by connecting round tubes with an outer diameter of 20mm, an inner diameter of 16mm, and a length of 400mm, and are welded and fixed together.

[0043] The mounting base 24 is connected to both ends of the crossbar 22. The mounting base 24 has a U-shaped structure, which can be fitted with rollers 21 and then upside down onto the telescopic diagonal bar 12 of the support frame 1, simplifying the assembly structure between rollers 21 and telescopic diagonal bar 12. After the material is transported, the mounting base 24 and rollers 21 can be directly removed from the telescopic diagonal bar 12 by lifting, making disassembly and assembly convenient.

[0044] Limiting rods 25 are provided at both ends of the longitudinal rod 23. The limiting rods 25 form a limiting structure, which simplifies the specific form of the limiting structure. In addition, the top of the limiting rod 25 is open, which also facilitates the movement of the tray 3 directly on the bracket 2.

[0045] Preferably, the drive structure 7 includes a fixed pulley 71, a drive pulley 72, and a traction rope 73. The support frame 1 is equipped with a fixed pulley 71 at one end of the guide rail and a drive pulley 72 at the other end. The traction rope 73 is wound in a loop between the fixed pulley 71 and the drive pulley 72. The bracket 2 is provided with a traction hook 26 for hooking and cooperating with the traction rope 73.

[0046] The drive structure 7 is formed by a fixed pulley 71, a drive pulley 72 and a traction rope 73. The fixed pulley 71 and the drive pulley 72 are respectively arranged at both ends of the support frame 1, forming the rotation path of the traction rope 73. The traction rope 73 is wound in a loop between the fixed pulley 71 and the drive pulley 72. When the drive pulley 72 rotates, it can drive the traction rope 73 to move in a loop, thereby driving the bracket 2 connected to the traction rope 73 to move.

[0047] In this embodiment, the traction rope 73 is a closed loop. After being wound around the fixed pulley 71 and the drive pulley 72, the traction rope 73 is slightly loose. When the traction rope 73 is tightened, a certain distance can be left to allow it to be wound around the traction hook 26 of the bracket 2, thus achieving the connection between the traction rope 73 and the bracket 2. The traction rope 73 is driven by friction with the fixed pulley 71 and the drive pulley 72.

[0048] In this embodiment, the towing hooks 26 are arranged on the limiting rods 25 of the bracket 2. There are two towing hooks 26, which are symmetrically arranged on the bracket 2 to ensure that both sides of the bracket 2 are under tension simultaneously, making it more stable during movement. Since the towing rope 73 and the towing hooks 26 are temporarily connected by a sleeve, after the bracket 2 moves from the bottom to the top on the support frame 1, the crew can remove the bracket 2 and use the towing hooks 26 to hook the bracket 2 under the towing rope 73. When the towing rope 73 moves in a circle, it can drive the bracket 2 back to the starting point on the ground to continue moving the pallet 3.

[0049] Preferably, the drive structure 7 further includes a drive motor and a handle, both of which are connected to the drive pulley 72 for transmission.

[0050] The drive motor and handle are both shown in the figure. Both the drive motor and handle are connected to the pulley transmission. Under normal conditions, the drive motor drives the drive pulley 72 to rotate, providing power for the movement of the bracket 2. In the absence of power, the handle can be driven to drive the drive pulley 72 to rotate, realizing the reciprocating transport of the bracket 2.

[0051] Preferably, the pallet 3 includes a box body 31 and at least two sets of support columns 32 arranged on the outside of the box body 31. The top of the box body 31 is provided with an opening. Each support column 32 has a plug 321 formed on its top and a slot 322 formed on its bottom. The slot 322 is for the plug 321 of adjacent pallets 3 arranged in a stack to be inserted and fitted.

[0052] The pallet 3 is formed by a box body 31 and a support column 32. The top of the box body 31 is open for crew members to place goods into the pallet 3. The support column 32 is provided on the outside of the box body 31, and plugs 321 and slots 322 are formed at both ends of the support column 32. When the pallets 3 are stacked, the plugs 321 can be inserted into the slots 322 of the adjacent pallets 3 to fix the pallets 3 and prevent them from tipping over, making the stacking more stable. The stacked pallets 3 can be stacked more reasonably, increasing the storage capacity of cold storage goods.

[0053] In this embodiment, the dimensions of the box 31 are 500mm in length and width and 300mm in height. The box 31 is a cuboid structure. There are four sets of support columns 32, which are arranged on the four sides of the box 31 to limit the position of the box 31.

[0054] Preferably, the tray 3 further includes a support arm 33, which is arranged on the top of the support column 32 and is vertically connected to the support column 32. The lifting frame 5 is provided with a slot 51 for supporting the support arm 33.

[0055] A support arm 33 is arranged on the pallet 3. The support arm 33 can be supported in the slot 51 of the lifting frame 5, providing a support point for the lifting frame 5 to lift the pallet 3, and also providing a support point for the transfer frame 4 to support the pallet 3. The slot 51 on the lifting frame 5 supports the support arm 33. While supporting the support arm 33, the slot 51 also limits the support arm 33 to prevent the pallet 3 from shaking.

[0056] In this embodiment, the lifting frame 5 includes a plate and two limiting columns. The two limiting columns are welded and fixed on the plate, and the gap between the two limiting columns forms a slot 51. The plate is connected to the lifting mechanism 6.

[0057] In this embodiment, the support arm 33 is a tubular structure made of the same material as the support column 32. The support arm 33 is vertically welded on each of the four support columns 32 so that the tray 3 is stably supported in four directions and the force is balanced.

[0058] Preferably, the transfer frame 4 includes multiple sets of connecting rods 41 connected end to end, casters 42 are arranged at the bottom of the connecting rods 41, and the sets of connecting rods 41 are connected to form a U-shaped structure to form a notch for the pallet 3 to enter and exit horizontally, and the pallet 3 is supported by the connecting rods 41.

[0059] The connecting rods 41 of the transfer frame 4 are connected to form a U-shaped structure. The notch in the U-shape allows the pallet 3 to be loaded into the transfer frame 4 horizontally, making it easier for crew members to move the pallet 3. In this embodiment, the connecting rods 41 have an outer diameter of 20mm, an inner diameter of 16mm, and a length of 600mm. There are three sets of connecting rods 41, which are welded together and fixed to each other. There are four casters 42, which are arranged at the four corners of the U-shaped transfer frame 4 to provide stable support for the transfer frame 4.

[0060] Preferably, the lifting mechanism 6 includes a first screw 61, a second screw 62, and a threaded sleeve 63. The threads of the first screw 61 and the second screw 62 have opposite directions. The first screw 61 is connected to the transfer frame 4, and the second screw 62 is connected to the lifting frame 5. The inner walls of the threaded sleeve 63 are provided with reverse threads at both ends, and the threaded sleeve 63 is threaded between the first screw 61 and the second screw 62.

[0061] The lifting mechanism 6 is formed by a first screw 61, a second screw 62, and a threaded sleeve 63. The first screw 61 is welded to the transfer frame 4, the second screw 62 is welded to the lifting frame 5, and the threaded sleeve 63 is connected between the first screw 61 and the second screw 62. Since the threads of the first screw 61 and the second screw 62 have opposite directions, and the two ends of the threaded sleeve 63 are provided with reverse threads, when the threaded sleeve 63 rotates, the first screw 61 and the second screw 62 will move closer to or further away from each other, thereby driving the lifting frame 5 to rise and fall.

[0062] In this embodiment, the threaded sleeve 63 has multiple circumferentially spaced mounting holes, and a handle 64 is inserted into each mounting hole, with the handle 64 movably mounted to the threaded sleeve 63. When rotating the threaded sleeve 63, the crew inserts the handle 64 into the mounting hole, and the handle 64 drives the threaded sleeve 63 to rotate. After rotating a certain angle, the handle 64 can be pulled out and inserted into another mounting hole, avoiding interference between the handle 64 and the tray 3.

[0063] The working process of this invention is as follows: When replenishing supplies to the ship, the crew adjusts the length of the telescopic diagonal bar 12 of the support frame 1, hooks the hook 11 on the rope diagonal bar onto the railing of the ship, assembles the bracket 2, fixed pulley 71, drive pulley 72 and traction rope 73 on the support frame 1, and sets the traction rope 73 on the traction hook 26 of the bracket 2. The roller 21 of the bracket 2 is rolled and assembled with the telescopic diagonal bar 12.

[0064] After the pallet 3 is loaded with goods, the crew members place the pallet 3 within the space enclosed by the horizontal bars 22 and the vertical bars 23 of the bracket 2. The limiting bar 25 is used to limit the pallet 3 to prevent it from shaking. The drive pulley 72 drives the towing rope 73 to rotate, and the towing rope 73 in turn drives the bracket 2 to move along the telescopic diagonal bar 12, transporting the pallet 3 from the ground to the hull. After the pallet 3 is in place, the crew members carry the pallet 3 off the bracket 2, and at the same time remove the towing rope 73 from the towing hook 26 of the bracket 2 and hang the bracket 2 on the lower towing rope 73. The towing rope 73 brings the bracket 2 back to the starting point for the next transport.

[0065] After the pallet 3 is removed from the bracket 2, the crew places the pallet 3 on the transfer frame 4 and uses the connecting rod 41 to support the support arm 33 of the bracket 2. Then, multiple pallets 3 are stacked on top of each other in sequence. The plugs 321 and slots 322 on the support pillars 32 of the pallet 3 are connected to each other to prevent the pallet 3 from shaking. When it is necessary to remove the upper pallet 3, the crew rotates the threaded sleeve 63 through the handle 64. The threaded sleeve 63 drives the second screw 62 to rise and fall, which in turn drives the lifting frame 5 to support the support arm 33, so as to lift the required pallet 3 for the crew to carry.

[0066] In summary, this invention provides a supply material transportation and transfer fixture. Its pallet can be loaded with materials to be transported and then placed on a support frame. A limiting structure on the support frame restricts the pallet's movement, preventing it from swaying. The support frame is mounted on a guide rail of a support frame via rollers. As the support frame moves on the support frame, it drives the pallet to move synchronously. When loading materials, the hooks of the support frame are attached to the ship's hull, with the bottom of the support frame resting on the ground. The support frame drives the pallet along the guide rail from the bottom to the top of the support frame, thus transporting the materials onto the ship. This achieves automated material handling, eliminating the need for personnel to carry materials up and down the ship's ramps, thereby reducing manpower requirements for replenishment. After the pallet is moved onto the ship's hull, personnel can load it onto the transfer frame of the retrieval device and stack it. By pushing the transfer frame, the materials can be transferred to the cold storage. A lifting mechanism lifts the stacked pallets, allowing operators to move them, improving retrieval efficiency, reducing the time and intensity of manual handling, and enhancing replenishment efficiency.

[0067] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
