Description

Technical Field

[0001] The utility model belongs to the technical field of marine engineering, in particular to a marine platform floating crane device with amplitude variation and anti-seismic buffering functions. Background Art

[0002] The offshore platform floating crane is an important equipment used in the field of marine engineering. It is mainly used for cargo loading and unloading, equipment installation and maintenance on offshore platforms. Therefore, it is very important in marine engineering. However, earthquakes often occur in the ocean, so it is necessary to reduce the impact of external factors on the floating crane.

[0003] At the same time, the application number is 202220864054.2, which is a rapid lifting system for a steel approach bridge. It includes a floating crane, which includes a floating platform and a crane arranged on the floating platform. The crane includes a boom and a rotating hoist mounted on the boom. The rotating hoist includes a crossbeam for connecting to a back cable arranged on the boom. The lower surface of the crossbeam is rotatably connected to a hook. The floating platform is provided with a driving device for driving the bridge section to rotate. This application uses the driving device to drive the bridge section to rotate, so that the floating crane can still adjust the direction of the bridge section when the bow of the floating crane is deflected toward the shore, thereby achieving rapid lifting of the cross-coast bridge section while avoiding the floating crane string running aground.

[0004] During use, an existing steel approach bridge rapid lifting system has a heavy boom, making it difficult to adjust the boom range when lifting and transporting heavy objects. It is also unable to reduce vibrations when the offshore platform floating crane device is vibrated, which is not conducive to the stable operation of the device and has poor performance.

[0005] Therefore, in order to solve the above problems, an offshore platform floating crane with amplitude variation and seismic buffering functions is proposed. Utility Model Content

[0026] Specifically, the bottom end of the support plate 3 is fixedly connected to a connecting rod 15, the bottom end of the connecting rod 15 is fixedly connected to a support 16, the inner side of the support 16 is rotatably connected to a rotating rod 17, one end of the rotating rod 17 is rotatably connected to a slider 18, there are two sliders 18, the outer side of the slider 18 is spirally connected to a bidirectional threaded rod 19, the outer side of the bidirectional threaded rod 19 is rotatably connected to a guide rail 20 to provide a guide for the movement of the slider 18, and one end of the bidirectional threaded rod 19 is rotatably connected to a servo motor 21.

[0027] Furthermore, a slide groove 22 is opened inside the U-shaped plate 8, and a connecting block 23 is slidably connected inside the slide groove 22, and the connecting block 23 is fixedly connected to the side of the sliding rod 9. Under the action of the connecting block 23, it is pushed by the first hydraulic rod 10 to slide inside the slide groove 22, thereby supporting and guiding the sliding rod 9.

[0028] Furthermore, the bottom end of the U-shaped plate 8 is fixedly connected to a triangular rod 24, and one end of the triangular rod 24 is fixedly connected to the boom 6. Under the action of the triangular rod 24, the U-shaped plate 8 can be made more stable, preventing the U-shaped plate 8 from breaking due to excessive external force.

[0029] It is worth noting that the top of the support plate 3 is fixedly connected to a second hydraulic rod 25, and the top of the second hydraulic rod 25 is fixedly connected to the lower bottom surface of the boom 6. If a large angle adjustment range is required, the second hydraulic rod 25 can be started to push the boom 6 to rotate, thereby realizing a large angle adjustment range of the device and increasing the performance of the device.

[0030] It is worth noting that the top of the support plate 3 is fixedly connected to a placement frame 26, and a counterweight block 27 is embedded inside the placement frame 26 to increase the counterweight so that the device can stably pull up the heavy object and prevent the hull 1 from tilting.

[0031] It is worth mentioning that a trapezoidal groove 28 is provided inside the guide rail 20, and the cross-sectional area of ​​the trapezoidal groove 28 is the same as the cross-sectional area of ​​the slider 18, which can prevent the slider 18 from falling off and facilitate the slider 18 to slide inside it, providing a guiding function.

[0032] It is worth emphasizing that the bottom end of the guide rail 20 is fixedly connected to the supporting base plate 29, and the bottom end of the supporting base plate 29 is fixedly connected to the anti-slip strip 30. Under the action of the anti-slip strip 30, the supporting base plate 29 can be prevented from sliding on the surface of the hull 1, thereby increasing friction and improving stability.

[0033] Among them, the hull 1, the rotary module 2, the first hydraulic rod 10, the cylinder 12, the servo motor 21 and the second hydraulic rod 25 are existing technologies and will not be repeated; at the same time, the utility model also includes a power supply, a controller and a switch, etc., which are not the main technical points of this patent and will not be repeated.

[0034] Working principle and process:

[0035] When the staff needs to lift and transport objects above the ocean, they first connect the lifting wire rope 5 to the object and pull the object up. A counterweight block 27 is placed inside the placement frame 26 fixedly connected to the top of the support plate 3 to increase the counterweight so that the device can lift the heavy object stably. When transportation is inconvenient and the amplitude of the device needs to be adjusted, the first hydraulic rod 10 is started to push the sliding rod 9 to move inside the U-shaped plate 8. Under the action of the connecting block 23, it is pushed by the first hydraulic rod 10 to slide inside the slide groove 22. Because the connecting block 23 is fixedly connected to the side of the sliding rod 9, it can support and guide the sliding rod 9. The sliding rod 9 drives the rotating arm 7 to rotate the angle, so that the lifting amplitude of the device is changed, which is convenient and fast. If a large angle adjustment amplitude is required, the second hydraulic rod 25 can be started to push the boom 6 to rotate, thereby realizing a large angle adjustment device amplitude and increasing the performance of the device. Under the action of the triangular rod 24, the U-shaped plate 8 can be made more stable to prevent the U-shaped plate 8 from breaking due to excessive external force. If the hull 1 is affected by earthquakes and waves during the operation of the device When shaking, the hull 1 applies pressure to the fixed block 11, and the fixed block 11 pushes the cylinder 12 to buffer the force. The spring 13 set on the outside can also buffer the force, increasing the seismic performance of the device, reducing the impact of vibration on the upper parts, preventing the hoisted objects from shaking too much and falling off, and increasing the stability and safety of the device. When the device rotates the angle through the rotary module 2, the servo motor 21 is started to drive the bidirectional threaded rod 19 to rotate, and the bidirectional threaded rod 19 drives the slider 18 to slide inside the guide rail 20. Because the cross-sectional area of ​​the trapezoidal groove 28 opened inside is the same as that of the slider 18, it can prevent the slider 18 from falling off and facilitate the sliding of the slider 18 inside it. The slider 18 drives the rotating rod 17 to rotate and pushes the lower guide rail 20 to move downward, so that it drives the supporting bottom plate 29 to contact the top surface of the hull 1 and press it tightly, thereby supporting the support plate 3, making the upper parts more stable and reducing the probability of shaking. Under the action of the anti-slip strip 30, the supporting bottom plate 29 can be prevented from sliding on the surface of the hull 1, increasing friction and improving stability.
