Description

Technical Field

[0001] This invention relates to the field of crane-related technical fields, specifically to a prefabricated earthquake-resistant marine crane frame. Background Technology

[0002] When carrying out material loading and unloading, equipment hoisting, and maritime rescue operations at ports, shipyards, and water operations sites, cranes are needed to assist in these operations. Floating cranes are a type of lifting equipment. A floating crane is a boom-type crane that can be installed on a dedicated floating vessel. It can not only perform hoisting operations, but it can also be used in marine engineering, dock loading and unloading, and other situations that require water-based operations. For example, when constructing an offshore platform-based observation station, a floating crane can be used to stably hoist the required observation instruments and equipment to facilitate the subsequent construction of the offshore platform-based observation station.

[0003] Most cranes lift heavy objects by winding them up with ropes. During lifting operations, there is no way to reduce sway or provide shock absorption. When operating at sea, they are easily affected by external wind and waves, causing the load to sway and potentially fall. To address these issues, a sway-reducing and shock-resistant offshore crane disclosed in existing technology (Chinese patent application number CN202510067092.3, application date 2025-01-16) can be referenced. This crane's adjustment... The segment frame, driven by the second threaded block, stably moves the auxiliary wheel, causing it to contact the auxiliary traction rope. This loosens the taut auxiliary traction rope, increasing the distance between the four sets of auxiliary traction ropes. At this point, the auxiliary traction ropes exert outward force on the fixed plate, reducing the swaying of a single main traction rope during lifting operations, resulting in good anti-sway performance. This also relates to existing technology (application number CN202411718399.7, application date 2018). A marine crane with a windproof and highly stable structure is disclosed in Chinese Patent No. 024-11-28. This crane is equipped with a limit clamping mechanism, which can effectively control the stability between the clamp and the main lifting rope. In conjunction with the hook connected to the main lifting rope, it can effectively control the stability between the connecting rope and the connecting seat. The positioning seat assembled with the connecting seat can effectively form a nested connection with the auxiliary lifting rope, thereby controlling the stability of the installation frame, preventing detachment, and increasing the stability of the lifting. Finally, referring to the prior art (Chinese Patent No. CN202411230391.6, application date 2024-09-04), a highly stable bottom-supported suspended marine crane is disclosed. The rear end of the stabilizing rope of this crane is equipped with a third guide wheel for limiting its movement. When the stabilizing rope sways, the third guide wheel drives the connecting rod to sway, thereby causing the connecting rod to drive the guide slider to slide left and right outside the guide slider. At this time, the elastic effect of the shock-absorbing spring and the energy absorption effect of the damping airbag are used to achieve effective shock absorption and maintain the stability of the stabilizing rope.

[0004] Although the above-mentioned devices can provide some shock absorption, offshore cranes are also installed on engineering vessels. Since engineering vessels need to travel on the sea, they may be affected by wind and waves, which may cause a large pendulum effect during the lifting operation, which is not conducive to the subsequent handling work.

[0005] Therefore, we propose a prefabricated seismic-resistant marine crane frame to address the problems mentioned above. Summary of the Invention

[0009] Preferably, a rubber ring is nested on the outer wall of the movable piston rod, and the outer side of the rubber ring is attached to the inner wall of the receiving sleeve. A solenoid valve is also provided at the end of the movable piston rod that extends into the receiving sleeve. The interior of the movable piston rod is hollow. An oil supply pipe is also connected to the side of the receiving sleeve away from the solenoid valve. The other end of the oil supply pipe is connected to the elastic telescopic cylinder.

[0010] Preferably, the vertically moving elastic telescopic cylinder is equipped with a return spring inside for mutual reset at both ends. The bottom position of the elastic telescopic cylinder is fixed to the top of the upper plate, and a roller is installed at the top position of the elastic telescopic cylinder. The outer side of the roller is also attached to the outer side of the auxiliary cable to achieve the raising of the auxiliary cable.

[0011] Preferably, the adjustment mechanism includes a fitting guide ring fitted to the outside of the traction rope, the two ends of the fitting guide ring being fixedly connected to the guide slider via a support rod, the outer side of the guide slider being slidably disposed on the inner side of the fixed plate, and the outer side of the fixed plate being fixed to the outer surface of the rotating column.

[0012] Preferably, the outer side of the guide slider is provided with a protrusion, the outer side of the protrusion is slidably disposed on the inner side of the fixed plate, and the outer side of the guide slider is in contact with the sidewalls of the two sets of elastic airbags.

[0013] Preferably, the elastic airbag is provided with a one-way air inlet, and the bottom outer sides of both sets of elastic airbags are connected to an air supply pipe through a branch pipe, and the branch pipe is provided with a one-way air outlet.

[0014] Preferably, the damping mechanism includes a fixed cylinder fixed at the bottom of the column, and a damping rod is fixed inside the fixed cylinder. The bottom outer side of the damping rod is slidably disposed inside the damping cylinder, and the damping cylinder and the inner side of the fixed cylinder are connected by a number of damping springs. An oil inlet pipe and an oil outlet pipe are also connected to the other side of the damping cylinder.

[0015] Preferably, the shock-absorbing springs are evenly distributed about the center of the damping cylinder, one end of the oil inlet pipe and the oil outlet pipe are connected to the hydraulic oil tank through the pump body, and a vent is provided on the outer side of the top of the hydraulic oil tank.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: The prefabricated earthquake-resistant marine crane frame significantly reduces the risk of pendulum swing through adaptive tension adjustment of the elastic telescopic cylinder, dissipation of swaying energy by elastic airbags, and dual energy absorption by damping springs and seawater damping; after position correction, the negative pressure adsorption mechanism, with its fitting plate and negative pressure adsorption plate, firmly adsorbs materials, adapting to objects of varying flatness and preventing slippage; furthermore, the entire machine features a modular prefabricated design, with detachable components, convenient factory prefabrication and on-site assembly, and the ability to replace wear parts individually, significantly reducing installation and maintenance costs and comprehensively improving the safety, stability, durability, and economy of offshore lifting operations. Specific details are as follows:

[0018] 1. The prefabricated structure design allows for detachable connections between the columns, hull, and various functional components via bolts. This not only facilitates factory prefabrication and reduces on-site installation difficulty and construction costs, but also enables individual disassembly and replacement of worn parts, reducing the time and economic investment required for overall machine maintenance.

[0019] 2. The negative pressure adsorption mechanism generates negative pressure by driving the moving piston rod to cooperate with the receiving sleeve through the driving component. Combined with the tight fit of the bonding plate, it can adapt to the material gripping needs of different flatness. Compared with the traditional hook-type hoisting, it effectively improves the firmness and applicability of material gripping.

[0020] 3. The linkage design of the elastic airbag, air supply pipe, and damping cylinder not only buffers the instantaneous tensile impact of the traction rope through the deformation of the airbag, but also increases the potential energy of the damping cylinder sliding on the outside of the damping rod by setting the swing block, thereby further reducing shock and damping.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-9 The present invention provides the following technical solution: a prefabricated earthquake-resistant marine crane frame.

[0033] Example 1: To facilitate the hoisting and handling of objects, please refer to the attached document. Figure 1 -Appendix Figure 4 The system includes a column 1, whose bottom is bolted to the hull, and a rotating column 2 rotatably mounted on top of the column 1. A winch 3 is installed at the upper end of the rotating column 2, and the output end of the winch 3 is connected to the top center of the upper plate 4 via a vertical cable. Four sets of auxiliary cables 5 are also tied to the outside of the vertical cable, and the bottom of the auxiliary cables 5 are connected to the four corners of the bottom plate 6. A driving component 7 is installed at the center of the bottom surface of the upper plate 4, and the driving component 7 acts on the inside of the connecting sleeve 8. A bonding plate 9 is fixed at the bottom of the connecting sleeve 8, and a negative pressure adsorption mechanism is provided on the outside of the connecting sleeve 8 near the upper plate 4 for negative pressure adsorption treatment of materials. The driving component 7 is composed of a drive motor and a threaded screw, and the outer side of the threaded screw is threaded to the inside of the connecting sleeve 8. The auxiliary mechanism includes a movable piston rod 11 fixed to the outer side of the connecting sleeve 8 near the upper plate 4, a receiving sleeve 12, and a negative pressure adsorption plate 10. The outer side of the movable piston rod 11 is slidably disposed inside the receiving sleeve 12. The bottom position of the receiving sleeve 12 is fixed to the top of the upper plate 4. The negative pressure adsorption plate 10 is installed on the surface of the bonding plate 9 and is connected to the movable piston rod 11 through a hose. A rubber ring is nested on the outer wall of the movable piston rod 11, and the outer side of the rubber ring is attached to the inner wall of the receiving sleeve 12. A solenoid valve is also provided at the end of the movable piston rod 11 that extends into the receiving sleeve 12. The interior of the movable piston rod 11 is hollow. An oil supply pipe 13 is also connected to the side of the receiving sleeve 12 away from the solenoid valve. The other end of the oil supply pipe 13 is connected to the elastic telescopic cylinder 14.

[0034] First, the column 1 is fixed to the preset position on the hull with bolts to complete the overall frame installation. During hoisting operations, the winch 3 at the top of the rotating column 2 is started, and the height of the upper plate 4 and the bottom plate 6 is adjusted by winding and unwinding the vertical cable. The four sets of auxiliary cables 5 move synchronously with the vertical cables, providing traction support from the corners of the bottom plate 6, initially limiting the swaying during hoisting. When materials need to be grabbed, the drive motor of the drive component 7 drives the threaded screw to rotate, and an elastic threaded tube needs to be nested on the outside of the threaded screw to avoid problems such as seawater corrosion and dust wear later. The threaded drive connecting sleeve 8 moves downward, so that the bonding plate 9 is close to the surface of the material. Figures 3-5 As shown, when the connecting sleeve 8 moves, it synchronously drives the moving piston rod 11 to slide inside the receiving sleeve 12. That is, the two sets of moving piston rods 11 slide relative to each other towards the outside of the upper plate 4 through the connecting sleeve 8. The sealing effect can be ensured by the rubber ring. The solenoid valve creates a negative pressure inside the receiving sleeve 12. When the negative pressure adsorption plate 10 adheres to the material, the solenoid valve is then opened. At this time, the negative pressure is transmitted to the negative pressure adsorption plate 10 through the hollow moving piston rod 11 and the hose, so as to achieve stable adsorption of the material adhered to the negative pressure adsorption plate 10.

[0035] Example 2: To avoid swaying during hoisting, please refer to the attached document. Figure 4 -Appendix Figure 7 The right side of the base plate 6 is connected to the winch 3 installed on the side of the rotating column 2 via a traction rope 15. An adjustment mechanism is provided on the outside of the traction rope 15, and one side of the adjustment mechanism is attached to one side of the elastic airbag 18. The vertically moving elastic telescopic cylinder 14 is equipped with a return spring inside for mutual reset at both ends. The bottom of the elastic telescopic cylinder 14 is fixed to the top of the upper plate 4, and a roller is installed at the top of the elastic telescopic cylinder 14. The outside of the roller is also attached to the outside of the auxiliary cable 5 to achieve the raising of the auxiliary cable 5. The adjustment mechanism includes the attachment mechanism on the outside of the traction rope 15. The guide ring 16 is fixedly connected to the outer shaft end of the guide slider 17 via a support rod at both ends. The outer side of the guide slider 17 is slidably disposed on the inner side of the fixed plate 19, and the outer side of the fixed plate 19 is fixed to the outer surface of the rotating column 2. The outer side of the guide slider 17 is provided with a protrusion, and the outer side of the protrusion is slidably disposed on the inner side of the fixed plate 19. The outer sides of the two sets of guide sliders 17 are in contact with the side wall of the elastic airbag 18. The elastic airbag 18 is provided with a one-way air inlet, and the bottom outer sides of the two sets of elastic airbags 18 are connected to an air supply pipe 20 through a branch pipe. The branch pipe is provided with a one-way air outlet.

[0036] Meanwhile, the oil inside the housing 12 flows into the elastic telescopic cylinder 14 through the oil supply pipe 13, driving it to extend and retract. The top roller then contacts the auxiliary cable 5, further assisting in adjusting the tension of the auxiliary cable 5 and enhancing hoisting stability. The return spring inside the elastic telescopic cylinder 14 can achieve return at both ends through its own elasticity. The roller installed on its top always contacts the auxiliary cable 5, providing stable lifting and support, reducing swaying caused by the slack of the auxiliary cable 5. When factors such as wind and waves cause the traction rope 15 to sway, the roller... The fitting guide ring 16, which is fitted on the outside of the traction rope 15, moves synchronously with the offset of the traction rope 15. Through the support rod, the guide slider 17 slides along the inside of the fixed plate 19. During the sliding process, the guide slider 17 squeezes the side wall of the elastic airbag 18. The elastic airbag 18 draws in air through the internal one-way air inlet to buffer the pressure. At the same time, it slowly exhausts the air through the bottom air pipe 20 and the one-way air outlet in the branch pipe to relieve pressure. The swaying energy of the traction rope 15 is converted into the deformation and exhaust energy of the elastic airbag 18, and finally the sway reduction and anti-sway of the hoisting system is achieved.

[0037] Example 3: This example differs from Example 2 in that it can be further damped to facilitate offshore operations. Please refer to the attached document. Figure 1 and attached Figure 7 -Appendix Figure 9 The bottom of the elastic airbag 18 is connected to the damping mechanism, which is installed at the bottom of the column 1. The damping mechanism includes a fixed cylinder 21 fixed at the bottom of the column 1, and a damping rod 22 is fixed inside the fixed cylinder 21. The bottom outer side of the damping rod 22 is slidably disposed inside the damping cylinder 24. The damping cylinder 24 and the inner side of the fixed cylinder 21 are connected by several sets of shock-absorbing springs 23. The other side of the damping cylinder 24 is also connected to an oil inlet pipe 25 and an oil outlet pipe 26. The shock-absorbing springs 23 are evenly distributed about the center of the damping cylinder 24. One end of the oil inlet pipe 25 and the oil outlet pipe 26 are connected to the hydraulic oil tank through the pump body. A vent is also provided on the top outer side of the hydraulic oil tank. A swing block 27 is also tied to the bottom outer side of the damping cylinder 24 by a steel wire rope. A protective net is provided on the outer side of the swing block 27 to prevent personnel injury during the swinging process of the swing block 27.

[0038] When the towing rope 15 sways due to sea waves, the guide slider 17 in Embodiment 2 will compress the elastic airbag 18. In this embodiment, the bottom of the elastic airbag 18 is directly connected to the damping mechanism, so that during the deformation buffering process, the elastic airbag 18 transmits the incompletely dissipated vibration impact force and its own deformation tension to the damping mechanism, providing a force transmission basis for subsequent deep vibration reduction and avoiding the accumulation of vibration energy in a local area, which would cause instability in the hoisting system. In the damping mechanism, the fixed cylinder 21 is fixed to the bottom of the column 1, and the damping rod 22 inside it slides against the damping cylinder 24. The damping cylinder 24 is dynamically connected to the inner side of the fixed cylinder 21 by multiple sets of damping springs 23 evenly distributed about the center of the damping cylinder 24. When the vibration impact force is transmitted to the damping mechanism, the damping cylinder 24 will slide axially or radially along the damping rod 22. At this time, the evenly distributed damping springs 23 will simultaneously undergo tensile or compressive deformation, using the elastic potential energy of the springs themselves to absorb part of the vibration energy, initially offsetting the impact of the vibration on the frame. The evenly spaced design can ensure that the damping force is uniform in all directions, avoiding the damping cylinder 24 from shifting due to uneven force. The externally connected oil inlet pipe 25 and oil outlet pipe 26 form a closed-loop hydraulic system with the pump body and hydraulic oil tank. When the damping cylinder 24 slides, its internal volume changes: when the volume increases, the oil inlet pipe 25 draws hydraulic oil from the hydraulic oil tank through the pump body; when the volume decreases, the oil outlet pipe 26 returns the hydraulic oil in the damping cylinder 24 to the hydraulic oil tank. When the hydraulic oil flows in the pipe, a damping force is generated due to viscous resistance. This damping force hinders the rapid sliding of the damping cylinder 24, converting the kinetic energy of the vibration into the heat energy of the hydraulic oil and releasing it slowly, thus achieving deep vibration energy reduction. In addition to dissipation, the vent at the top of the hydraulic oil tank can balance the air pressure inside the tank in real time, preventing hydraulic system failure due to oil pressure fluctuations and ensuring stable damping effect. The bottom of the damping cylinder 24 is tied to the swing block 27 by a steel wire rope. When the damping cylinder 24 vibrates, it will swing in the opposite direction due to inertia. The tension of the steel wire rope constrains the swing of the damping cylinder 24, further limiting the swing amplitude of the damping cylinder 24, and helping to improve the shock absorption stability of the damping mechanism. Furthermore, the swing of the swing block 27 can further improve the overall shock absorption effect.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
