Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of shipbuilding, specifically to a ship lifting device. Background Technology
[0002] There are some small but heavy components on the hull. In order to lift and move them, lifting eye plates are usually fixedly installed above the structure where these components are installed. When it is necessary to lift the component, a manual hoist is installed on the lifting eye plate, and then the manual hoist is connected to the component. The component can be lifted by operating the manual hoist. Then, the component is moved using a trolley or other equipment.
[0003] Marine cargo cranes are used to lift and place items that are basically in a straight line between two points. During use, it is difficult to adjust the reversing position of the lifting device according to the lifting needs. Manual labor is required to pull the lifted materials and then place them into the cargo hold, which consumes a lot of time and labor after lifting. Summary of the Invention
[0004] The purpose of this invention is to provide a ship lifting device to solve the above-mentioned defects caused by the prior art.
[0005] A ship lifting device includes a base, a winch, and a cylinder. A rolling bearing is connected to the outer side of the base, and a tray is connected to the outer side of the rolling bearing. A shifting mechanism is provided on the outer side of the tray. The shifting mechanism adjusts the angle of the support arm according to the usage requirements, thereby shifting and raising / lowering the material at the bottom end of the support arm. A displacement mechanism is provided directly below the support arm, which adjusts the position of the support arm, thereby adjusting the distance between the support arm and the ship's extension, facilitating the lifting of materials of different sizes. The winch is connected to the outer side of the support arm.
[0006] Preferably, the shifting mechanism includes a tray, a positioning seat, a support arm, a gear plate, a motor, and a gear. The positioning seat is located directly above the tray, and the support arm is connected to the inner end of the positioning seat. The gear plate is located directly below the tray, and the motor is meshed with the outer side of the gear plate. The motor is installed inside the base, and the gear plate is meshed with the outer side of the gear.
[0007] Preferably, the motor meshes with the outer side of the gear disk via a gear connected to its output end.
[0008] Preferably, the tray is connected to the inner end of the base via a rolling bearing connected to the outer side.
[0009] Preferably, the displacement mechanism includes a rectangular support plate, a counterweight, a slider, a guide groove, and a cylinder. Multiple sets of counterweights are arranged on one side of the upper part of the rectangular support plate, and a slider is arranged directly below the rectangular support plate. A guide groove is connected to the outer side of the slider and is located on the outer side of the tray. A cylinder is connected through one side of the tray, and the output end of the cylinder is connected to one side of the slider.
[0010] Preferably, the tray is connected to one side of the slider via a cylinder located on one side.
[0011] Preferably, the tray is connected to the outside of the slider through a guide groove at its top.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] 1. During use, based on the size of the ship and the cargo lifting requirements, on the one hand, the rectangular pallet is displaced at the top of the pallet, thereby adjusting the extension distance of the rectangular pallet and the support arm, so that cargo of the corresponding size can be lifted with a reasonable extension distance. On the other hand, the cylinder pulls the slider and the rectangular pallet connected to the top, thereby pulling the cargo on the outside of the ship to the ship's deck surface, reducing the time and labor required for cargo transfer.
[0014] 2. Simultaneously, the motor drives the gear to rotate, which in turn drives the positioning seat and the bottom tray to rotate, thereby causing the support arm to rotate to one side of the ship's deck. This facilitates the release of goods onto the ship's deck or into the cargo hold located below the deck via a winch, thus saving time during the transfer of goods. Attached Figure Description

[0023] like Figures 1 to 5 As shown, a ship lifting device includes a base 1, a winch 9, and a cylinder 16. A rolling bearing 15 is connected to the outer side of the base 1, and a tray 2 is connected to the outer side of the rolling bearing 15. A shifting mechanism 5 is provided on the outer side of the tray 2. The shifting mechanism 5 adjusts the angle of the support arm 7 according to the usage requirements, thereby shifting and raising the material at the bottom end of the support arm 7. A displacement mechanism 8 is provided directly below the support arm 7. The displacement mechanism 8 adjusts the position of the support arm 7, thereby adjusting the distance between the support arm 7 and the ship's extension, which is convenient for lifting materials of different sizes. The winch 9 is connected to the outer side of the support arm 7.
[0024] In this embodiment, the shifting mechanism 5 includes a tray 2, a positioning seat 6, a support arm 7, a gear 10, a motor 11, and a gear 13. The positioning seat 6 is located directly above the tray 2, and the support arm 7 is connected to the inner end of the positioning seat 6. The gear 10 is located directly below the tray 2, and the motor 11 is meshed with the outer side of the gear 10. The motor 11 is installed inside the base 1. The gear 13 is meshed with the gear 10 on the outer side, and the bottom end of the tray 2 is shifted through the gear 13.
[0025] In this embodiment, the motor 11 meshes with the outer side of the gear disk 10 through the gear 13 connected to the output end. The motor 11 drives the gear 13 to rotate, thereby switching the direction of the support arm 7 and the rectangular support plate 3.
[0026] In this embodiment, the tray 2 is connected to the inner end of the base 1 through a rolling bearing 15 connected to the outside, thereby reducing the friction of the tray 2 during rotation.
[0027] In this embodiment, the displacement mechanism 8 includes a rectangular pallet 3, a counterweight 4, a slider 12, a guide groove 14, and a cylinder 16. Multiple sets of counterweights 4 are arranged on one side of the upper part of the rectangular pallet 3. A slider 12 is arranged directly below the rectangular pallet 3. A guide groove 14 is connected to the outer side of the slider 12. The guide groove 14 is opened on the outer side of the pallet 2. A cylinder 16 is connected through one side of the pallet 2. The output end of the cylinder 16 is connected to one side of the slider 12. The position of the support arm 7 is adjusted by the slider 12, which facilitates the adjustment of the lifting position according to the size of the goods.
[0028] In this embodiment, the tray 2 is connected to one side of the slider 12 via a cylinder 16 located on one side. The cylinder 16 drives the slider 12 to move, thereby switching the direction of the tray 2.
[0029] In this embodiment, the tray 2 is connected to the outside of the slider 12 through the guide groove 14 opened at the top, and the rectangular support plate 3 set at the top of the tray 2 is displaced and adjusted by the slider 12.
[0030] In practical applications, this type of ship lifting device includes the following tasks:
[0031] Step 1: Before use, first install the base 1 on the deck of the ship, and at the same time make part of the support arm 7 extend out of the deck to facilitate the hoisting of cargo or fishing nets at the dock. Then, according to the size of the cargo or fishing net, open the cylinder 16 to push the slider 12 set on one side. The slider 12 drives the bottom end of the rectangular support plate 3 to move, so that the slider 12 moves outside the guide groove 14. After adjusting the position of the winch 9 and the support arm 7, open the winch 9 to vertically lift the cargo.
[0032] Step 2: After the winch 9 lifts the cargo above the ship's deck, the operator can open the cylinder 16 again and use the cylinder 16 to push the slider 12 set on one side inward, so that the support arm 7 drives the winch 9 and the hoisted cargo to move towards the ship's deck side, making it easier for the operators on the deck to pull and control the cargo. At the same time, the operator pre-installs the corresponding weight or number of counterweights 4 on one side of the rectangular pallet 3 to ensure the stability of the rectangular pallet 3 during rotation and hoisting.
[0033] Step 3: Then, depending on the location of the deck or the cargo hold below the deck, turn on the motor 11, use the motor 11 to drive the gear 13 to rotate, use the gear 13 to mesh with the gear plate 10, use the gear plate 10 to drive the pallet 2 and the support arm 7 set at the top to switch the direction, so that the winch 9 set at the bottom of the support arm 7 and the hoisted goods are aligned with the ship's cargo hold, and then turn off the motor 11.
[0034] Step 4: Use the toothed disc 10 to switch the direction of the pallet 2 and the rectangular support plate 3 at the top, and switch the direction of the support arm 7. The pallet 2 rotates inside the base 1 through the rolling bearing 15 on the outside. Use the winch 9 to release the goods vertically, thereby completing the lifting and placement of the goods.
[0035] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
