Description

Technical Field

[0001] The present invention relates to the technical field of lifting devices, and more specifically, to a lifting device and method for a ship cabin module. Background Art

[0002] The so-called cabin modularization is a cabin construction method that involves independently carrying out construction work on the ship's living cabins on land, installing various equipment and accessories, and building standardized independent cabin units with unified interfaces. The units are then hoisted onto the ship as a whole, in order to reduce the workload on board, shorten the shipbuilding cycle, and improve work efficiency.

[0003] In the field of shipbuilding, during the process of transporting modular living cabins from land to the hull in the dock, in order to solve the shortcoming of directly hanging the cabin for transportation, which may cause damage to the cabin, a hanging basket is generally used to transport the cabin. The cabin can be lifted by lifting the hanging basket, and the hook does not contact the cabin to protect the cabin. However, after the cabin is placed in the hanging basket, when the crane transports the hanging basket, the hanging basket may shake due to inertia or wind, which may cause the cabin to move in the hanging basket and hit the inside of the hanging basket, which may also cause damage to the cabin. In addition, the displacement of the cabin will affect the center of gravity of the hanging basket, making the collision more serious. Summary of the invention

[0014] A method for a hoisting device for a ship cabin module includes the following operating steps:

[0015] S1. After the forks of the forklift are placed on the top of the connecting shaft by the staff, the forks of the forklift are moved downward, so that the connecting shaft drives the rotating plate to move downward, and the rotating plate drives the front baffle to move upward through the second steel wire rope, and the opening of the front baffle is realized. Then the forklift continues to move, and the forklift places the ship cabin module on the top of the placing plate. After the ship cabin module is placed, after the staff drives the forklift out of the inside of the transportation groove, due to the gravity of the front baffle being greater than the gravity of the rotating plate, the front baffle moves downward under the action of gravity, and the front baffle drives the rotating plate to reset through the second steel wire rope, so that the front baffle can block and limit the ship cabin module, and the device can more smoothly block the ship cabin module;

[0016] S2. After the ship cabin module is placed on the top of the placement plate by the staff, when the device is lifted, the support frame drives the ship cabin module to be lifted. At the same time, under the action of gravity, the ship cabin module drives the placement plate to move downward. The placement plate pushes the L-shaped fixing frame to rotate, so that the vertical rod of the L-shaped fixing frame clamps and fixes both sides of the ship cabin module. When the ship cabin module is lifted, the position of the ship cabin module is fixed again, and the positioning of the ship cabin module is more stable and firm.

[0017] S3. Through the rotation of the L-shaped fixing frame, the L-shaped fixing frame drives the second transmission rod to rotate. The second transmission rod moves inside the push groove, so that the second transmission rod pushes the slider to move, and the slider pushes the power transmission rod to move. And under the restriction of the support frame, the power transmission rod pushes the pressing plate to move downward, so that the pressing plate presses and positions the top of the ship cabin module, making the positioning and fixing of the ship cabin module more convenient, and at the same time enabling the ship cabin module to be hoisted more smoothly.

[0018] S4. When the device is hoisted by the first steel wire rope, through the upward movement of the first steel wire rope, the first steel wire rope drives the U-shaped power blocking frame to move upward, and the U-shaped power blocking frame blocks one side of the L-shaped fixing frame, so that the L-shaped fixing frame can more stably position and fix the ship cabin module. After the extension leg contacts the ground first, the first steel wire rope is released. The U-shaped power blocking frame moves downward and resets under the action of gravity. When the extension leg slowly slides into the extension groove under the action of the damper spring, the second support leg contacts the ground. After the second support leg contacts the ground, the placement plate moves upward, and the L-shaped fixing frame contacts the fixation of the ship cabin module, enabling the ship cabin module to be transported out of the device more smoothly. Through the upward movement of the L-shaped blocking frame, the L-shaped blocking frame blocks the rotating plate, so that the rotating plate cannot move downward when the device is hoisted, thereby enabling the ship cabin module to be hoisted more smoothly.

[0019] S5. When the device is placed, after the extension leg contacts the ground first, the first steel wire rope is released. Under the action of gravity, the device makes the extension leg slide into the extension groove, and the extension leg drives the U-shaped power blocking frame to move downward and reset through the driving gear. When the extension leg slowly slides into the extension groove under the action of the damper spring, the second support leg contacts the ground. After the second support leg contacts the ground, the placement plate moves upward, and the L-shaped fixing frame contacts the fixation of the ship cabin module, enabling the ship cabin module to be transported out of the device more smoothly.

[0020] The advantages of the present invention are:

[0021] 1. The present invention provides a lifting device and method for a ship cabin module. The ship cabin module drives a placement plate to move downward under the action of gravity, and the placement plate pushes an L-shaped fixing frame to rotate, so that the vertical rods of the L-shaped fixing frame clamp and fix the two sides of the ship cabin module, so that when the ship cabin module is lifted, the position of the ship cabin module is fixed again, and the positioning of the ship cabin module is made more stable and firm.

[0022] 2. The present invention provides a lifting device and method for a ship cabin module. By making the gravity of the front baffle greater than the gravity of the rotating plate, the front baffle moves downward under the action of gravity, and the front baffle drives the rotating plate to reset through the second steel wire rope, so that the front baffle can block and limit the ship cabin module, and the device can block the ship cabin module more smoothly.

[0023] 3. The present invention provides a lifting device and method for a ship cabin module. Under the restriction of a support frame, a power transmission rod pushes the pressing plate downward, so that the pressing plate presses and positions the top of the ship cabin module, making the positioning and fixing of the ship cabin module more convenient and enabling the ship cabin module to be lifted more smoothly.

[0024] 4. The present invention provides a lifting device and method for a ship cabin module. When the extension leg slowly slides into the extension groove under the action of a damper spring, the second support leg contacts the ground. After the second support leg contacts the ground, the placement plate moves upward, and the L-shaped fixing frame is in fixed contact with the ship cabin module, so that the ship cabin module can be more smoothly transported out of the device. The L-shaped blocking frame moves upward to block the rotating plate, so that the rotating plate cannot move downward when the device is lifted, thereby enabling the ship cabin module to be lifted more smoothly.

[0035] A slot 48 extending to the top of the placement plate 12 is provided on the top of the bottom plate 1 , and the slot 48 enables a forklift to place the ship cabin module on the top of the placement plate 12 more smoothly.

[0036] After the staff places the fork of the forklift on the top of the connecting shaft 43, the fork of the forklift moves downward, so that the connecting shaft 43 drives the rotating plate 7 to move downward, and the rotating plate 7 drives the front baffle 41 to move upward through the second steel wire rope 39, and the front baffle 41 is opened, so that the forklift continues to move, and the forklift places the ship cabin module on the top of the placement plate 12. When the ship cabin module is placed, after the staff drives the forklift out of the transport groove 6, the gravity of the front baffle 41 is greater than the gravity of the rotating plate 7, so that the front baffle 41 moves downward under the action of gravity, and the front baffle 41 drives the rotating plate 7 to reset through the second steel wire rope 39, so that the front baffle 41 can block and limit the ship cabin module, and the device can block the ship cabin module more smoothly, making the lifting of the ship cabin module more convenient.

[0037] The gravity transmission limit device includes an L-shaped fixing frame 14, which is arranged inside the movable groove 10, and a rotating shaft 28 is fixedly connected to one side of the first support leg 30, and the inside of the L-shaped fixing frame 14 is rotatably connected to the surface of the rotating shaft 28. The cross section of the L-shaped fixing frame 14 is L-shaped, and the number of the L-shaped fixing frames 14 is four.

A rubber layer 45 is provided on one side of the L-shaped fixed frame 14, and the rubber layer 45 can provide certain protection for the ship cabin module.

[0038] The second transmission rod 15 extends to the inside of the push groove 46 on one side close to the push groove 46, and the movable groove 16 is sleeved on the limit shaft 18. Through the rotation of the L-shaped fixing frame 14, the L-shaped fixing frame 14 drives the second transmission rod 15 to rotate, and the second transmission rod 15 moves inside the push groove 46, so that the second transmission rod 15 pushes the slider 24 to move, and the slider 24 pushes the power transmission rod 26 to move, and the pressure plate 27 is restricted by the support frame 2, so that the power transmission rod 26 pushes the pressure plate 27 to move downward, so that the pressure plate 27 presses and positions the top of the ship cabin module, making the positioning and fixing of the ship cabin module more convenient, and at the same time enabling the ship cabin module to be lifted more smoothly.

[0039] A spring 25 is fixedly connected between the two sliders 24 . The spring 25 is movably sleeved on the limit shaft 18 . The spring 25 is compressed and reset by the relative movement of the two sliders 24 .

[0040] A limiting rod 29 is fixedly connected to one side of the inclined plate 4, and four second supporting legs 32 are fixedly connected to the bottom of the placement plate 12. A limiting groove 31 extending to the outside of the second supporting leg 32 is opened inside the second supporting leg 32. The surface of the limiting rod 29 is slidably connected to the inside of the limiting groove 31. Through the mutual cooperation between the limiting rod 29 and the limiting groove 31, the moving direction of the second supporting leg 32 and the placement plate 12 is limited, and the placement plate 12 can only move up and down. The height of the second supporting leg 32 is the same as that of the first supporting leg 30. The transverse rod of the L-shaped fixing frame 14 is set at the bottom of the placement plate 12. After the staff places the ship cabin module on the top of the placement plate 12, when the device is lifted, the support frame 2 drives the ship cabin module to be lifted, and at the same time, the ship cabin module drives the placement plate 12 to move downward under the action of gravity, and the placement plate 12 pushes the L-shaped fixing frame 14 to rotate, so that the vertical rods of the L-shaped fixing frame 14 clamp and fix the two sides of the ship cabin module, so that when the ship cabin module is lifted, the position of the ship cabin module is fixed again, and the positioning of the ship cabin module is made more stable and firm, so that the device can transport and lift the ship cabin module more smoothly.

[0041] Specifically, an extension slot 34 is provided at the bottom of the first support leg 30, and an extension leg 33 extending to the outside of the extension slot 34 is slidably connected inside the extension slot 34, and a damper spring 35 is fixedly connected to the top of the extension leg 33. The damper spring 35 is an existing structure and will not be elaborated on here. The top of the damper spring 35 is fixedly connected to the inner wall of the extension slot 34, and the damper spring 35 can be compressed and reset by moving the extension leg 33. The force of the damper spring 35 on the extension leg 33 can make the extension leg 33 contact the ground first, and under the action of gravity, the extension leg 33 slides into the interior of the extension slot 34, and the damper spring 35 is compressed.

[0042] The hoisting and fixing device includes a connecting plate 23. The bottom of the connecting plate 23 is fixedly connected to the top of the support frame 2. A transmission groove 44 extending to the outside of the connecting plate 23 is formed inside the connecting plate 23. A first steel wire rope 22 is arranged inside the transmission groove 44. The number of the connecting plate 23 and the first steel wire rope 22 is four. A second transmission roller 20 is rotatably connected to the top of the support frame 2. A top plate 21 is arranged on the top of the second transmission roller 20. Two symmetrical first transmission rollers 19 are rotatably connected to the top of the support frame 2. The two first transmission rollers 19 are arranged on the left and right sides of the support frame 2. A U-shaped power retaining frame 11 is slidably connected inside the moving groove 10. The cross-section of the U-shaped power retaining frame 11 is U-shaped. One end of the first steel wire rope 22 close to the top of the U-shaped power retaining frame 11 is fixedly connected to the top of the U-shaped power retaining frame 11. The surface of the first steel wire rope 22 is in transmission connection with the surfaces of the second transmission roller 20 and the first transmission roller 19. One end of the first steel wire rope 22 passes through the inside of the transmission groove 44, then bypasses the second transmission roller 20 and is fixedly connected to the top of the U-shaped power retaining frame 11 through the surface of the first transmission roller 19. When the device hoists the device through the first steel wire rope 22, the upward movement of the first steel wire rope 22 drives the U-shaped power retaining frame 11 to move upward, and the U-shaped power retaining frame 11 blocks one side of the L-shaped fixing frame 14, so that the L-shaped fixing frame 14 can more stably position and fix the ship cabin module. After the extension leg 33 contacts the ground first, the first steel wire rope 22 is released. The U-shaped power retaining frame 11 moves downward and resets under the action of gravity. When the extension leg 33 slowly slides into the extension groove 34 under the action of the damper spring 35, the second support leg 32 contacts the ground. After the second support leg 32 contacts the ground, it moves upward on the placing plate 12, and the L-shaped fixing frame 14 contacts the ship cabin module for fixing, so that the ship cabin module can be more smoothly transported out of the inside of the device.

[0043] An L-shaped retaining frame 9 is fixedly connected to one side of the U-shaped power retaining frame 11. A limiting plate 37 is fixedly connected to the side of the U-shaped power retaining frame 11 away from the L-shaped retaining frame 9. Grooves are formed on the front and rear sides of the bottom plate 1. Through the cooperation of the movement of the L-shaped retaining frame 9 and the limiting plate 37 with the grooves, the moving direction of the U-shaped power retaining frame 11 is restricted, and the device can operate more smoothly. A hidden groove 8 communicating with the inside of the rotating groove 5 is formed at the top of the inclined plate 4. The surface of the L-shaped retaining frame 9 is slidably connected to the inside of the hidden groove 8. By moving the L-shaped retaining frame 9 upward, the L-shaped retaining frame 9 blocks the rotating plate 7, so that the rotating plate 7 cannot move downward when the device is hoisted, and thus the ship cabin module can be hoisted more smoothly.

[0044] On one side of the first support leg 30, a power transmission groove 47 extending into the interior of the extension groove 34 is provided. An active gear 36 is rotatably connected inside the power transmission groove 47. Tooth teeth are provided on one side of the U-shaped power blocking frame 11 close to the active gear 36, and tooth teeth are also provided on one side of the extension leg 33 close to the active gear 36. Both the extension leg 33 and the U-shaped power blocking frame 11 are meshed with the surface of the active gear 36 through the tooth teeth.

[0045] After the extension leg 33 first contacts the ground, the first steel wire rope 22 is released. Under the action of gravity, the device makes the extension leg 33 slide into the interior of the extension groove 34, and the extension leg 33 drives the U-shaped power blocking frame 11 to move downward and reset through the active gear 36.

[0046] A method for a hoisting device for a ship cabin module includes the following operation steps:

[0047] S1. After the forklift forks are placed on the top of the connecting shaft 43 by the staff, the forklift forks move downward, so that the connecting shaft 43 drives the rotating plate 7 to move downward, and the rotating plate 7 drives the front baffle 41 to move upward through the second steel wire rope 39, and the front baffle 41 is opened. Then the forklift continues to move, and the forklift places the ship cabin module on the top of the placing plate 12. After the ship cabin module is placed, after the staff drives the forklift out of the interior of the transport groove 6, due to the gravity of the front baffle 41 being greater than the gravity of the rotating plate 7, the front baffle 41 moves downward under the action of gravity, and the front baffle 41 drives the rotating plate 7 to reset through the second steel wire rope 39, so that the front baffle 41 can block and limit the ship cabin module, and the device can block the ship cabin module more smoothly;

[0048] S2. After the staff places the ship cabin module on the top of the placing plate 12, when the device is hoisted, the support frame 2 drives the ship cabin module to be hoisted. At the same time, the ship cabin module drives the placing plate 12 to move downward under the action of gravity. The placing plate 12 pushes the L-shaped fixing frame 14 to rotate, so that the vertical rod of the L-shaped fixing frame 14 clamps and fixes both sides of the ship cabin module. When the ship cabin module is hoisted, the position of the ship cabin module is fixed again, and the positioning of the ship cabin module is more stable and firm;

[0049] S3. By rotating the L-shaped fixing bracket 14, the L-shaped fixing bracket 14 drives the second transmission rod 15 to rotate. The second transmission rod 15 moves inside the push groove 46, causing the second transmission rod 15 to push the slider 24 to move, and the slider 24 to push the power transmission rod 26 to move. Under the restriction of the support frame 2, the power transmission rod 26 pushes the pressing plate 27 to move downward, enabling the pressing plate 27 to press and position the top of the ship cabin module, making the positioning and fixing of the ship cabin module more convenient and enabling the ship cabin module to be lifted more smoothly.

[0050] S4. When the device is lifted by the first steel wire rope 22, as the first steel wire rope 22 moves upward, the first steel wire rope 22 drives the U-shaped power blocking frame 11 to move upward, and the U-shaped power blocking frame 11 blocks one side of the L-shaped fixing bracket 14, enabling the L-shaped fixing bracket 14 to more stably position and fix the ship cabin module.
