It should be noted that, a movable space is formed in the radial arm 200, when the output end 410 of the driving mechanism 400 drives the sliding structure 300 to slide along the extending direction of the radial arm 200, the sliding structure 300 can slide from the radial arm 200 to the outside of the free end 220 through the movable space, and the movable space provides various alternative stopping positions for the sliding structure 300, so that the cloud beam 700 connected with the sliding structure 300 can adapt to different use height requirements, and the application range of the lifting structure is improved.

As an alternative implementation of this embodiment, first, the driving mechanism 400 is utilized to initially drive the sliding structure 300 to slide along the extending direction of the radial arm 200, and the sliding structure 300 is stopped in the movable space or outside the free end 220, so that the cloud beam 700 connected to the sliding structure 300 is lowered or lifted to a required position;

Then, if the position of the cloud beam 700 needs to be adjusted, the lifting mechanism 500 is used to drive the radial arm 200 to rotate upwards around the mounting end 210 in a direction away from the base 100 to lift the sliding structure 300, or rotate downwards in a direction close to the base 100 to lower the sliding structure 300, so that the sliding structure 300 correspondingly lifts or lowers along with the radial arm 200 relative to the base 100, and correspondingly drives the cloud beam 700 connected with the sliding structure 300 to lower or lift to another required position;

after that, if the position of the cloud beam 700 still needs to be adjusted, the driving mechanism 400 is used to drive the sliding structure 300 to slide along the extending direction of the radial arm 200 again, and the sliding structure 300 is stopped in the movable space or outside the free end 220, so that the cloud beam 700 connected with the sliding structure 300 is lowered or lifted to another required position, and the height of the Yun Liang beam 700 can be adjusted multiple times, so that the Yun Liang beam 700 can adapt to drilling platforms with different heights, and the applicability of the cloud beam 700 is improved.

In implementation, the lifting structure drives the sliding structure 300 to move along the extending direction of the radial arm 200 through the driving mechanism 400, so that the height and the position of the cloud beam 700 can be accurately adjusted, the operation process is accelerated, repeated operation caused by improper position adjustment is reduced, and the operation efficiency and the accuracy are remarkably improved.

The swing arm 200 of the lifting structure ensures that the lifting structure has stable support, and the sliding structure 300 can stably slide in the extending direction of the swing arm 200 under the limit action of the swing arm 200, so that the vibration and impact generated in the operation process of the cloud beam 700 are reduced, and the operation risk is reduced.

The lifting structure can adjust the angle of the radial arm 200 relative to the base 100 through the lifting mechanism 500 to adjust the position of the sliding structure 300 relative to the base 100, so as to adapt to the operation requirements of different heights and positions, and the lifting structure has adaptability and flexibility both on drilling platforms of different heights and when the cloud beams 700 of different sizes and weights need to be lifted, thereby meeting the wide operation environments and operation requirements.

It should be appreciated that the base 100 serves as a supporting base for the entire lifting structure, ensures stability of the sliding structure 300 when driven by the driving mechanism 400 and moves along the radial arm 200, and improves reliability of the lifting structure for stability of the radial arm 200 when driven by the lifting mechanism 500 and rotates around the mounting end 210, the radial arm 200 not only provides support for the lifting mechanism 500, but also provides a limiting base for the sliding process of the sliding structure 300, so that the sliding process of the sliding structure 300 is easier to control, the driving mechanism 400 drives the sliding structure 300 to move along the extending direction of the radial arm 200, and the sliding structure 300 can be extended out of the free end 220 of the radial arm 200 or retracted into the radial arm 200 according to actual operation requirements, so that the position of the cloud beam 700 can be flexibly adjusted to adapt to variable drilling floor heights.

As another alternative implementation manner of this embodiment, for integrally managing the control pipeline of the lifting structure, the lifting structure further includes a drag chain, where the drag chain is laid in the radial arm 200, so as to reduce the occupation of the control pipeline and the drag chain to the bearing area of the radial arm 200, and one end of the drag chain is connected with the sliding structure 300, and one end of the drag chain is fixed on the radial arm 200, so that the drag chain can move along with the sliding structure 300 at one end of the sliding structure 300.

According to the technical scheme, stable support is provided for lifting of the cloud beam 700 through the base 100, the lifting process and position adjustment of the Yun Liang 700 are more stable and accurate by utilizing the radial arm 200 and the sliding structure 300 in sliding connection with the radial arm 200, the driving mechanism 400 enables the sliding structure 300 to extend out of the free end 220 from the inside of the radial arm 200 along the extending direction of the radial arm 200, or retract out of the free end 220 into the radial arm 200, the height of the cloud beam 700 can be adjusted for multiple times, the Yun Liang can adapt to drilling floor surfaces with different heights, the operation flexibility and the application range of the operation process are improved, the sliding structure 300 can extend out of the radial arm 200 from the free end 220, the position adjustment range of the Yun Liang is not limited by the length of the radial arm 200, the transportation capacity is improved, in addition, the lifting mechanism 500 is matched with the sliding structure 300 to optimize the distribution of lifting force, the problem that in the lifting process, the large lifting force is difficult to process and the drilling floor surface capacity with different heights is poor in the prior art is effectively solved, the operation difficulty and risk are remarkably reduced, the drilling efficiency is improved, the drilling frequency and the operation frequency is easy to be applied to the double operation and the maintenance requirement is lowered, and the operation and maintenance cost is easy to be easy to realize.
