Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering equipment, in particular to a wave compensation marine crane base. Background Art

[0002] Offshore cranes, also known as ship cranes, are heavy machinery installed on the decks of marine structures (such as ships) and designed specifically for loading and unloading cargo. Known for their powerful lifting capacity, exceptional impact resistance, superior braking performance, high safety, and remarkable operational efficiency, they are widely used in the field of marine engineering equipment. Whether operating on rough seas or at busy ports, offshore cranes provide strong support for the smooth operation of maritime trade with their solid and reliable performance.

[0003] Existing offshore crane bases usually use a three-degree-of-freedom adjustable base to adapt to the angle adjustment of its operation at sea. When facing larger waves and more biased angles, it cannot compensate and adjust well, resulting in severe shaking when hoisting heavy objects in big waves, leading to dangerous situations.

The top of the rotating disk 3 is fixedly connected to the supporting base 31; the motor can be used to drive the rotating disk 3 to rotate, thereby driving the supporting base 31 to rotate, which can drive the offshore crane to rotate.

[0027] In some technical solutions, such as Figure 1-Figure 3The pressure regulating assembly includes an oblique support rod 4, and the oblique support rod 4 is evenly arranged in six groups. A through slot is opened on the top of the oblique support rod 4, and an irregular support block 41 is fixedly connected to the bottom of the through slot. A decompression spring 42 is fixedly connected to the top of the irregular support block 41, and a first connecting block 43 is fixedly connected to the top of the decompression spring 42. The top of the first connecting block 43 is fixedly connected to the support inner rod 44. A fixed support beam 45 is provided at the top of the support base 31 and one side of the oblique support rod 4. One end of the fixed support beam 45 is fixedly connected to the top of the support base 31. The other end of the fixed support beam 45 is fixedly connected to the outside of the oblique support rod 4; when the hull shakes, the hull tilts to one side, and the supporting inner rod 44 on the tilted side will squeeze the supporting inner rod 44 downward. When the supporting inner rod 44 is under pressure, it squeezes downward 32, thereby squeezing the decompression spring 42, and the supporting inner rod 44 on the other side will not be squeezed downward, thereby achieving a certain relative balance, so that the offshore crane will not shake with the shaking angle of the hull, and the fixed support beam 45 is used to play the role of fixed support, thereby enhancing the stability of the oblique support rod 4.

When the hull shakes, the hull tilts to one side, and the supporting inner rod 44 on the tilted side will squeeze the supporting inner rod 44 downward. When the supporting inner rod 44 is under pressure, it squeezes 32 downward, thereby squeezing the decompression spring 42, and the supporting inner rod 44 on the other side will not be squeezed downward. In this way, a certain relative balance is achieved, so that the offshore crane will not sway with the swaying angle of the hull.
