Description

Technical Field

[0001] This invention relates to the field of compartment hoisting equipment, specifically a modular compartment hoisting equipment. Background Technology

[0002] Modular cabin construction refers to a method of building living quarters on land by independently constructing and installing various equipment and accessories to create standardized, independent cabin units with unified interfaces. These units are then hoisted onto the ship as a whole, reducing onboard workload, shortening the shipbuilding cycle, and improving work efficiency.

[0003] In order to address the drawback of directly slinging the modular compartments during transport, which can damage them, a basket is typically used. The compartment is then transported within the basket, and the compartment is lifted by hoisting the basket. The lifting hook does not contact the compartment, thus protecting it.

[0004] Chinese patent CN108483221B discloses a marine modular unit compartment hoisting device, which protects the modular unit compartment during hoisting by setting up a support frame and prevents the modular unit compartment from being damaged during hoisting.

[0005] However, the above structure only protects the cabin through the base. After the cabin is placed in the basket, when the crane is transporting the basket, the basket may sway due to inertia or wind, which may cause the cabin to move and collide with the inside of the basket, resulting in damage to the cabin. Furthermore, the displacement of the cabin will affect the center of gravity of the basket, making the collision more serious. Summary of the Invention

[0006] Based on this, the purpose of the present invention is to provide a modular cabin hoisting device to solve the technical problem that when a crane is transporting a basket, the basket may sway due to inertia or wind, causing the cabin to move and collide with the inside of the basket, which may also cause damage to the cabin. Furthermore, the cabin displacement may affect the center of gravity of the basket, making the collision more serious.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a modular compartment hoisting device, comprising a hoisting frame, wherein a set of first accumulators is provided on both sides of the hoisting frame, and the gas end of the piston plate in each set of first accumulators is connected to a clamping plate outside the first accumulator; multiple hydraulic cylinders are provided on both sides of the bottom surface inside the hoisting frame, and pressure plates are connected to the movable ends of the hydraulic cylinders; a first pipe is connected between the oil end of each first accumulator and a hydraulic cylinder on the same side; a second pipe is connected between the first pipes on each side of the hoisting frame; a second accumulator is provided on both sides of the hoisting frame, and the second pipe is connected to one side of the oil end of the second accumulator; the other side of the oil end of the second accumulator is connected to the hydraulic cylinder on the same side; a second one-way valve is provided between the second accumulator and the hydraulic cylinder; a one-way valve is provided on each of the first pipes; a manual valve is provided on each of the second pipes; and a connecting pipe is connected between the hydraulic cylinders on each side of the hoisting frame.

[0008] By adopting the above technical solution, the first accumulator can push the clamping plate to clamp the chamber through the compression of hydraulic oil. The chamber can press down the oil cylinder through the pressure plate, so that the hydraulic oil in the oil cylinder can do work outward. Both the first pipe and the second pipe can be used to conduct hydraulic oil. The second accumulator can store some hydraulic oil during unloading, so that the clamping plate opens a part. The second check valve can prevent hydraulic oil from entering the second accumulator when clamping. After the clamping plate fixes the chamber, the check valve can restrict the clamping plate to prevent the hydraulic oil from flowing back and causing the clamping plate to open when descending or shaking, due to the reduced force applied by the chamber to the pressure plate. The manual valve can be used to control the backflow of hydraulic oil.

[0009] The present invention is further configured such that each of the four corners of the top surface of the hanging frame is connected to a hanging arm, and a hanging plate is connected between the hanging arms.

[0010] By adopting the above technical solutions, rigid booms and lifting platforms can make hoisting more stable.

[0011] The present invention is further configured such that the top surface of the suspended platform is provided with a plurality of lifting rings, and each lifting ring is detachably connected to a hook, and each hook is connected to a lifting rope.

[0012] By adopting the above technical solution, the combination of the lifting ring and the hook facilitates the movement of the lifting frame.

[0013] The invention is further configured such that a plurality of hook blocks are rotatably connected in the middle of the hanging plate, and springs are connected between the outer side of the hook blocks and the hanging plate. A limiting block is provided on the outer sleeve of the hanging rope, and a fixing block that cooperates with the hook blocks is slidably connected to the bottom surface of the limiting block.

[0014] By adopting the above technical solution, the spring can push the hook block to hook onto the fixed block, thereby reinforcing the hoisting.

[0015] The present invention is further configured such that a frame door is provided at one end of the hanging frame.

[0016] By adopting the above technical solution, the frame can be closed.

[0017] The present invention is further configured such that the side walls and top surface of the hanging frame are both frame structures, and X-shaped reinforcing tubes are provided on the side walls of the hanging frame and the end away from the frame door.

[0018] By adopting the above technical solutions, the frame structure can reduce the overall weight of the device, and the X-shaped reinforcing tube can increase the strength of the device.

[0019] The present invention is further configured such that a slot is formed on the pressure plate.

[0020] By adopting the above technical solution, the slot is designed to allow the forklift's forks to lift the hatch from the bottom.

[0021] The present invention is further configured such that the gas in both the first accumulator and the second accumulator is nitrogen.

[0022] By adopting the above technical solution, nitrogen is used as an inert gas to prevent it from corroding the inner walls of the first and second accumulators, thereby extending their service life.

[0023] In summary, the present invention has the following main beneficial effects:

[0024] This invention connects clamping plates to the first accumulator on both sides of the lifting frame. After the compartment is placed into the lifting frame, its own weight presses down on the pressure plate, causing hydraulic oil in the cylinder to enter the first accumulator through the first pipe. The gas in the first accumulator is compressed, and the piston plate is pushed to one side, which in turn pushes the clamping plate to clamp and fix the compartment, preventing it from shaking. During unloading, opening the manual valve allows the nitrogen in the first accumulator to push the hydraulic oil into the second accumulator, causing the clamping plate to return to its original position a certain distance, allowing the compartment to be removed. After the compartment is removed, the compressed gas in the first and second accumulators fully expands and returns to its original position, pushing the pressure plate to its original position. The manual valve can then be closed to complete the transfer, resulting in better protection for the compartment. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of the present invention will now be described.

[0033] A modular compartment hoisting device, such as Figure 1-3 As shown, the system includes a lifting frame 1. The top surface of the lifting frame 1 is equipped with a transport mechanism to facilitate the lifting and transport of the lifting frame 1 and its internal compartments. During use, the basket may sway in the air due to wind, causing the internal compartments to move and collide with the inner wall of the basket. Furthermore, the movement of the compartments will cause the center of gravity of the basket to shift, further exacerbating the swaying of the compartments. Therefore, clamping and fixing mechanisms are provided on both sides of the lifting frame 1, and a frame door 11 is provided at one end of the lifting frame 1. During transport, the compartments are clamped and the frame door 11 is closed to prevent the swaying during transport from causing the compartments to move and collide with the inner wall of the lifting frame 1, resulting in damage.

[0034] The specific structure of the dispatching organization is as follows: Figure 3 and Figure 4 As shown, a hanging plate 14 is connected to the top surface of the hanging frame 1 via a boom 13. A lifting ring 15 is provided on the top surface of the hanging plate 14. A hook 17 for connecting a lifting rope 16 is detachably provided on the lifting ring 15. The lifting rope 16 is connected to the crane, and the crane can lift and transport the hanging frame 1 via the lifting rope 16 and the hanging plate 14.

[0035] The specific structure of the detachable connection between the lifting ring 15 and the hook 17 is not limited. For example, a plate that can be rotatably connected to the notch of the hook 17 can be used to close the notch. After the hook 17 is hung on the lifting ring 15, the elastic material pushes the plate to block the notch and prevent the lifting ring 15 from falling off. When disassembling, the pusher plate is disengaged from the notch, so that the hook 17 can be removed from the lifting ring 15 through the notch.

[0036] During the transportation process, the lifting frame 1 may fall due to the detachment of the welded joint of the lifting ring 15 or the disengagement of the hook 17 from the lifting ring 15. The falling frame 1 may injure pedestrians and render both the frame 1 and the cabin unusable. To avoid this, a limiting block 21 is fitted onto the lifting rope 16, with a fixing block 20 slidably connected to the bottom surface of the limiting block 21. Multiple hooks that cooperate with the fixing block 20 are rotatably connected to the top surface of the lifting plate 14. Block 18, and springs 19 are connected between the outer side of hook block 18 and hanging plate 14. After hook 17 is hung with hanging ring 15, fixing block 20 is inserted between hook blocks 18. Spring 19 can push hook block 18 to hook fixing block 20. Under normal conditions, fixing block 20 and limit block 21 are slidably connected and do not affect the operation of hanging rope 16. When hook 17 or hanging ring 15 falls off, hook block 18 can be tightly hooked with fixing block 20 due to the weight of hanging frame 1 to prevent hanging frame 1 from falling.

[0037] For example, the clamping and fixing mechanism can adopt an existing structure, such as using a hydraulic cylinder to drive the clamping part to tighten and clamp the object. However, when using a hydraulic cylinder to clamp the chamber, it is necessary to install components such as a power supply on the lifting frame, and multiple cylinders are required to push the clamping part. In addition, the cylinders need to be equipped with a separate control system, which is costly.

[0038] Therefore, the clamping and fixing mechanism in this embodiment adopts a more environmentally friendly method, the specific structure of which is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, two first accumulators 2 are installed on both sides of the hanging frame 1, and the air surface of the piston plate inside the first accumulator 2 is connected to a clamping plate 3. Three hydraulic cylinders 5 are installed on both sides of the bottom surface inside the hanging frame 1. The movable end of the hydraulic cylinder 5 is connected to a pressure plate 4. The oil end of each first accumulator 2 is connected to a hydraulic cylinder 5 on the same side through a first pipe 6. A one-way valve 7 is installed on each first pipe 6. A second pipe 8 is connected between the first pipes 6 on the same side. One end of the second pipe 8 is connected to a second accumulator 10 located on the side of the hanging frame 1, and the other end of the oil end of the second accumulator 10 is connected to a hydraulic cylinder 5. A manual valve 9 is installed on the second pipe 8. A connecting pipe 12 is connected between the hydraulic cylinders 5 on each side of the hanging frame 1. After the compartment is placed on the pressure plate 4, the weight of the compartment pushes the pressure plate 4 and the movable end of the cylinder 5 down, forcing hydraulic oil into the interior of the first accumulator 2 through the first pipe 6. This compresses the nitrogen gas inside the first accumulator 2, pushing the clamping plate 3 to clamp the compartment and prevent it from shaking during transport. When unloading, the manual valve is opened, and the hydraulic oil flows back to the second accumulator 10 through the second pipe 8. The second accumulator 10 distributes part of the hydraulic oil, and the first accumulator 2 can rebound part of it, causing the clamping plate 3 to loosen the compartment. The forklift can then transport the compartment out. After the compartment is separated from the pressure plate 4, the first accumulator 2 and the second accumulator 10 can be fully reset. The hydraulic oil is then pushed back into the cylinder 5, and the manual valve 9 is closed to complete the hoisting.

[0039] A second check valve 22 is provided between the second accumulator 10 and the oil cylinder 5. The second check valve 22 prevents hydraulic oil from entering the second accumulator 10 when the compartment presses down on the pressure plate 4, which would make it difficult for the clamping plate 3 to clamp the compartment.

[0040] Of course, the connecting pipe 12 allows the hydraulic oil in each cylinder 5 to pass through freely, so that when the pressure plate 4 presses down on the cylinder 5, the cylinder 5 descends synchronously, and when the hydraulic oil flows back, the cylinder 5 rises synchronously.

[0041] The accumulator mentioned in the clamping and fixing mechanism is existing technology. For example, accumulators are used for buffering and resetting of aircraft arresting cables. The principle is that when the pressure increases, oil enters the accumulator and the gas is compressed until the system pipeline pressure no longer rises. In this embodiment, when the pipeline pressure drops, the compressed air expands and forces the oil into the circuit, thereby slowing down the drop in pipeline pressure. When the cylinder 5 is pressed down, the hydraulic oil is squeezed into the first accumulator 2, pushing the internal piston plate to move, which compresses the air. When the piston plate moves, it can also push the clamping plate 3 to move. When the manual valve 9 is opened, the gas density in the second accumulator 10 is low. Therefore, the expansion of the high-density gas in the first accumulator 2 causes some hydraulic oil to be squeezed into the second accumulator 10 until the gas density in the two accumulators is equal.

[0042] This invention creatively utilizes the gravity generated by the first accumulator 2 and the second accumulator 10 to drive the clamping and loosening of the clamping plate 3, eliminating the need for an external drive mechanism, thus being more energy-efficient and environmentally friendly. The purpose of clamping the object is to prevent the compartment from shaking. After clamping is completed, the device can be lifted and transported by a crane.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
