Description

[0002] The ship is equipped with lifting tools, which can be used to lift the cargo onto the deck of the ship, so that the staff can place the cargo in the next step. However, the ship is located on the sea and is often affected by the sea waves and shakes, which in turn causes the lifted cargo to shake, making the lifting work impossible, and even damaging the cargo in serious cases. Therefore, it is necessary to keep the lifted cargo as stable as possible.

[0003] In the prior art, some lifting tools are provided with a supporting arm, a lifting assembly and a clamping assembly. The lifting assembly can move along the supporting arm, and the clamping assembly is used to clamp the cargo.

[0041] Embodiment 1

[0042] This embodiment provides a ship hoisting device, such as Figures 1 to 3As shown, the stability of the goods can be improved, and the goods can be prevented from being damaged due to shaking. The hoisting work can be carried out smoothly, and the efficiency and safety of the hoisting work can be ensured, and the extension of the working cycle can be avoided.

[0043] like Figures 1 to 3 As shown, the ship lifting device includes a lifting structure 1, a loading assembly 2 and a supporting assembly 3. Among them, the lifting structure 1 includes a frame 11, a lifting member 12 and a hanging connection assembly. One end of the frame 11 is configured to be arranged on the hull 100 of the ship, and the lifting member 12 is rotatably arranged at the other end of the frame 11 around the horizontal direction, and the length of the lifting member 12 along the horizontal direction is adjustable. The hanging connection assembly is arranged at the end of the lifting member 12 away from the frame 11. The loading assembly 2 includes a loading frame 21 and a magnet 22, and the loading frame 21 is detachably connected to the hanging connection assembly. The magnet 22 is adsorbed on the outer wall of the loading frame 21, and the loading frame 21 is configured to be used for loading cargo. The supporting assembly 3 includes a first driving mechanism 31 and a supporting plate 32, the shell of the first driving mechanism 31 is arranged on the frame 11, and the output end of the first driving mechanism 31 is transmission-connected to the supporting plate 32. The first driving mechanism 31 is used to drive the support plate 32 to move in the horizontal direction, so that the support plate 32 is directly opposite to the loading frame 21 , and a restraining force can be generated between the support plate 32 and the magnet 22 .

[0044] like Figure 1 As shown, when the ship lifting device is used to lift cargo, firstly, the cargo is loaded into the loading frame 21, and the magnet 22 is adsorbed on the outer wall of the loading frame 21, and the loading frame 21 is connected to the hanging connection assembly, and then the lifting member 12 is driven to rotate in the horizontal direction, so that the lifting member 12 drives the loading frame 21 to rise, and then the first driving mechanism 31 is controlled to drive the support plate 32 to move in the horizontal direction until the support plate 32 and the loading frame 21 are vertically opposite, so that the support plate 32 and the magnet 22 on the outer wall of the loading frame 21 can interact with each other, and a force of about 1 / 400 Nm is generated between the two. The binding force is applied to keep the loading frame 21 stable, and then the length of the hanging connection assembly is adjusted vertically, and at the same time, the first driving mechanism 31 is driven to rotate in the horizontal direction to make the support plate 32 rise vertically. In this process, the length of the lifting component 12 and the first driving mechanism 31 are also adjusted in the horizontal direction, so that the support plate 32 and the loading frame 21 are relatively stationary in the vertical and horizontal directions, that is, the two are always facing each other, until the loading frame 21 is moved above the hull 100, and finally the lifting component 12 is driven to rotate in the horizontal direction to make the loading frame 21 descend onto the hull 100, so as to facilitate the staff to load and unload goods.

[0045] By setting the support plate 32 to be opposite to the loading frame 21, the support plate 32 and the magnet 22 on the outer wall of the loading frame 21 interact with each other to generate a restraining force. Under the action of the restraining force, the loading frame 21 loaded with goods can remain stable, which can improve the stability of the goods and prevent the goods from being damaged due to shaking. Moreover, during the movement of the goods, the support plate 32 and the loading frame 21 are always opposite to each other, that is, the support plate 32 can always provide a restraining force for the loading frame 21, and the restraining force can effectively suppress the swing and shaking of the loading frame 21 during the lifting process, so that the loading frame 21 maintains stable movement during the lifting process, thereby allowing the lifting work to proceed smoothly, ensuring the efficiency and safety of the lifting work and avoiding extending the working cycle.

[0046] It should be noted that the magnet 22 in this embodiment includes a permanent magnet 22 .

[0047] In this embodiment, the first driving mechanism 31 includes a telescopic pole, and the support plate 32 includes a copper plate. In other embodiments, a metal plate such as an iron plate or a steel plate can be provided as the support plate 32 according to actual needs, which is not limited here.

[0048] It should be noted that the ship hoisting device provided in this embodiment can be used for hoisting cargo placed on the ground, and can also be used for hoisting cargo between two floating ships. During the hoisting process of cargo, since the support plate 32 and the magnet 22 on the outer wall of the loading frame 21 interact to generate a restraining force, the restraining force of the support plate 32 on the magnet 22 can keep the loading frame 21 stable, thereby avoiding the violent swing of cargo caused by the shaking of the ship, so that even if the hoisting work is carried out between two floating ships, it can be carried out smoothly, which can greatly improve the hoisting operation capacity under complex sea conditions and provide stronger protection for offshore operations.

[0049] Optionally, the lifting member 12 includes a lifting arm 121 and a second driving mechanism 122. The shell of the second driving mechanism 122 is rotatably connected to the frame 11, and the output end of the second driving mechanism 122 is retractable relative to the shell of the second driving mechanism 122, and the output end of the second driving mechanism 122 is rotatably connected to the lifting arm 121. The lifting arm 121 is rotatably connected to the frame 11 around the rotation axis A. After the goods are loaded on the loading frame 21, the output end of the second driving mechanism 122 can be controlled to be retracted, and the lifting arm 121 can be driven by the second driving mechanism 122 to rotate around the rotation axis A, that is, the lifting arm 121 is rotated around the horizontal direction, so that the lifting arm 121 lifts the loading frame 21. By setting the second driving mechanism 122, the lifting of the goods can be achieved, and a supporting force is provided for the loading frame 21, which is conducive to maintaining the stability of the loading frame 21, and the structure is simple and easy to operate.

[0050] Exemplarily, the second driving mechanism 122 includes a telescopic oil cylinder or a telescopic electric cylinder, etc.

[0051] Optionally, the lifting boom 121 includes a first arm section, a second arm section and a third driving mechanism. One end of the first arm section is rotatably connected to the frame body 11, and the other end is hollow inside. The second arm section is movably arranged in the first arm section along the extension direction of the first arm section, and the shell of the third driving mechanism is rotatably connected to the first arm section. The output end of the third driving mechanism is retractable relative to the shell of the third driving mechanism, and the output end of the third driving mechanism is transmission-connected to the second arm section.

[0052] When it is necessary to lift cargo, start the third driving mechanism so that the output end of the third driving mechanism drives the second arm segment to move within the first arm segment, thereby extending or shortening the overall length of the lifting cantilever 121, so that the lifting cantilever 121 can drive the loading frame 21 to move to the place where the cargo is placed, so as to facilitate the loading of cargo. When the cargo is loaded, the third driving mechanism is controlled again to drive the second arm segment to move within the first arm segment, so that the lifting cantilever 121 can drive the loading frame 21 loaded with cargo to move onto the ship. The structure is simple and easy to operate, which is convenient for the staff to load and unload cargo.

[0053] Exemplarily, the third driving mechanism includes a telescopic oil cylinder or a telescopic electric cylinder, etc.

[0054] The lifting structure is optional, and the support assembly 3 further includes a fourth drive mechanism 33. The shell of the fourth drive mechanism 33 is rotatably connected to the frame 11, and the output end of the fourth drive mechanism 33 is retractable relative to the shell of the fourth drive mechanism 33, and the output end of the fourth drive mechanism 33 is rotatably connected to the shell of the first drive mechanism 31. When the cargo is loaded into the loading frame 21, the length of the lifting connection assembly is adjusted vertically so that it drives the loading frame 21 to rise, and at the same time, the output end of the fourth drive mechanism 33 is controlled to be retracted, and the first drive mechanism 31 can rotate around the horizontal direction under the drive of the fourth drive mechanism 33, so that the first drive mechanism 31 drives the support plate 32 to rotate around the horizontal direction, so that the support plate 32 and the loading frame 21 are always vertically opposite and relatively static, so that the restraining force between the two remains unchanged, which is conducive to maintaining the stability of the loading frame 21, avoiding the swing of cargo caused by the shaking of the hull 100, and making the lifting work go smoothly.

[0055] In this embodiment, the hanging connection assembly includes a rotating motor, a winding shaft, a rotating shaft, a hanging connection member 141 and a hook. The housing of the rotating motor is arranged on the lifting cantilever 121, and the output end of the rotating motor is rotationally connected to the winding shaft, and the rotating motor is used to drive the winding shaft to rotate. The rotating shaft is arranged at one end of the lifting cantilever 121 away from the frame 11, and one end of the hanging connection member 141 is wound on the winding shaft. The other end of the hanging connection member 141 is wound around the rotating shaft and connected to the hook. The hanging connection member 141 has a winding state and an unfolding state to reduce or increase the vertical length of the hanging connection member 141.

[0056] When it is necessary to lift the cargo, the rotating motor is started, and the rotating motor drives the winding shaft to rotate, so that the hanging connection member 141 is rolled up onto the winding shaft, reducing the vertical length of the hanging connection member 141, so that it drives the loading frame 21 loaded with cargo to rise. When the cargo below is needed, the rotating motor is controlled to drive the winding shaft to rotate in the opposite direction, so that the hanging connection member 141 on the winding shaft is unfolded, increasing the vertical length of the hanging connection member 141, so that it drives the loading frame 21 loaded with cargo to descend.

[0057] Exemplarily, the hanging connection member 141 includes a steel wire rope or the like.

[0058] Optionally, a hooking groove is provided on the loading frame 21, and the hook can be hooked with the hooking groove. When the hook is connected and fixed to the loading frame 21, the hook can be hooked with the hooking groove. By providing the hooking groove, the firmness of the connection between the hook and the loading frame 21 can be improved, thereby further improving the stability of the loading frame 21 during lifting, avoiding slipping between the hook and the loading frame 21, and preventing the loading frame 21 from falling.

[0059] Alternatively, if Figures 1 to 3 As shown, the ship hoisting device also includes a monitoring module 4 and a control module. The monitoring module 4 includes a signal transmitter 41 and a signal receiver 42. The signal transmitter 41 is arranged at one end of the second arm section away from the first arm section, and the signal receiver 42 is arranged on the support plate 32. The control module is communicatively connected with the first drive mechanism 31, the second drive mechanism 122, the third drive mechanism, the fourth drive mechanism, the rotating motor and the signal receiver 42.

[0060] After the cargo is loaded into the loading frame 21, the control module controls the third driving mechanism to drive the first arm segment to rotate, so that the lifting cantilever 121 drives the loading frame 21 to lift, and then controls the first driving mechanism 31 to drive the support plate 32 to move in the horizontal direction. During this process, the signal transmitter 41 on the second arm segment continuously transmits signals and is received by the signal receiver 42 on the support plate 32, so that the distance between the support plate 32 and the second arm segment in the horizontal direction and in the vertical direction can be obtained. When it is detected that the positions of the support plate 32 and the second arm segment in the horizontal direction coincide and are vertically opposite (that is, the support plate 32 is vertically opposite to the second arm segment), the signal receiver sends a signal to the control module, and then the control module controls the rotation The rotating motor rotates to make the hanging connecting piece 141 reeled on the reel to lift the loading frame 21, and at the same time controls the extension and retraction of the fourth driving mechanism 33, so that it drives the support plate to rotate in the horizontal direction through the third driving mechanism, and controls the first driving mechanism 31 and the second driving mechanism 13 to move in the horizontal direction at the same time, so that the lifting cantilever 121 drives the loading frame 21 to move above the ship. During this process, the loading frame 21 and the support plate 32 are always opposite to each other, that is, the positions of the loading frame 21 and the support plate 32 are relatively stationary in the horizontal direction and in the vertical direction, so that the magnet 22 and the support plate 32 always interact with each other to generate a restraining force, which provides a restraining force to the loading frame 21, which is conducive to its stability and ensures the smooth progress of the lifting work.

[0061] Exemplarily, the control module includes a PLC controller.

[0062] In this embodiment, a receiving chamber is disposed at one end of the frame 11 close to the lifting member 12 , and the control module is disposed in the receiving chamber.

[0063] Alternatively, if Figures 1 to 3 As shown, the support assembly 3 further includes a support inclined rod 33. One end of the support inclined rod 33 is connected to the frame body 11, and the other end is connected to the first driving mechanism 31. By providing the support inclined rod 33, the support force of the first driving mechanism 31 on the support plate 32 can be improved, which is conducive to keeping the support plate 32 in a horizontal state, avoiding the restraining force generated by the interaction between the support plate 32 and the magnet 22 due to the inclination of the support plate 32, thereby keeping the loading frame 21 stable and avoiding its shaking.

[0064] Alternatively, if Figures 1 to 3As shown, the frame 11 includes a base 111 and a rod 112. The base 111 is arranged on the hull 100, one end of the rod 112 is arranged on the base 111, and the other end is rotatably connected to the lifting member 12. The cross-sectional area of ​​the base 111 is larger than the cross-sectional area of ​​the rod 112. By setting the base 111 in direct contact with the hull 100, the contact area between the frame 11 and the hull 100 can be increased, the pressure can be dispersed, and the stability can be improved. At the same time, the base 111 can also serve as a buffer layer to reduce the influence of the deformation of the hull 100 on the rod 112.

[0065] Embodiment 2

[0066] This embodiment provides a ship, such as Figure 1 As shown, it includes a hull 100 and the ship hoisting device as described above, and the ship hoisting device is arranged on the hull 100. By arranging the ship hoisting device, it is convenient to stably hoist the cargo onto the hull 100, avoiding the shaking of the hull 100 caused by wind and waves to affect the hoisting work of the cargo, which is conducive to ensuring the working efficiency and safety of the hoisting work.

[0067] Embodiment 3

[0068] This embodiment provides a method for using a ship hoisting device, using the ship hoisting device as described above. The method for using the ship hoisting device includes:

[0069] The cargo is loaded into the loading frame 21, and the magnet 22 is adsorbed on the outer wall of the loading frame 21; the loading frame 21 is connected to the hanging connection assembly, the lifting member 12 is driven to rotate in the horizontal direction to lift the loading frame 21, and the first driving mechanism 31 is driven to drive the support plate 32 to move in the horizontal direction until the support plate 32 is directly opposite to the loading frame 21; the length of the hanging connection assembly is adjusted vertically, and the first driving mechanism 31 is driven to rotate in the horizontal direction at the same time, so that the support plate 32 rises vertically, and the support plate 32 and the loading frame 21 are relatively stationary in the vertical direction; the length of the lifting member 12 is adjusted in the horizontal direction, and the first driving mechanism 31 is controlled to drive the support plate 32 to move in the horizontal direction, so that the loading frame 21 and the support plate 32 are simultaneously moved to the top of the hull 100, and the support plate 32 and the loading frame 21 are relatively stationary in the horizontal direction; the lifting member 12 is driven to rotate in the horizontal direction, so that the loading frame 21 descends to the hull 100.

[0070] By controlling the first driving mechanism 31 to drive the support plate 32 to move to face the loading frame 21, the support plate 32 interacts with the magnet 22 on the outer wall of the loading frame 21 to generate a restraining force. Under the action of the restraining force, the loading frame 21 loaded with goods can remain stable, which can improve the stability of the goods and prevent the goods from being damaged due to shaking. Moreover, during the movement of the goods, the support plate 32 and the loading frame 21 are always facing each other, that is, the support plate 32 can always provide a restraining force for the loading frame 21, and the restraining force can effectively suppress the swinging and shaking of the loading frame 21 during the lifting process, so that the loading frame 21 maintains stable movement during the lifting process, thereby allowing the lifting work to proceed smoothly, ensuring the efficiency and safety of the lifting work and avoiding extending the working cycle.

[0071] It should be noted that after the loading frame 21 moves to the top of the hull 100, the first driving mechanism 31 can continue to be controlled to drive the support plate 32 to retract, so that there is no obstruction under the loading frame 21, and then the lifting component 12 can be driven to rotate in the horizontal direction to lower the loading frame 21 onto the hull 100, and finally the cargo can be unloaded by the staff; or the lifting component 12 can be directly driven to rotate in the horizontal direction to lower the loading frame 21 onto the support plate 32, and then the cargo can be unloaded by the staff.
