[0002] Water is a basic element for human survival, and electricity is the main energy source for social development. Water conservancy and hydropower projects are projects that regulate and utilize water resources through engineering or non-engineering measures based on the study of the natural characteristics of water. In the construction of water conservancy and hydropower projects, some heavy objects such as reinforced concrete slabs require lifting equipment to facilitate the transportation of heavy objects.

[0003] There are many types of lifting equipment generally used in water conservancy and hydropower. One of them is a column lifting device, which is simple in structure and easy to use. However, since the boom is fixedly connected to the column, it takes up more space for subsequent storage. At the same time, when lifting objects, the center of gravity of the objects shifts, causing the lifted objects to shake, resulting in unstable lifting.

[0004] Therefore, there is an urgent need for a lifting head for water conservancy and hydropower engineering that can solve the above problems. Utility Model Content

[0008] Preferably, a servo motor 1 is installed in the internal mounting groove of the column, and a threaded rod 1 is connected to the output shaft of the servo motor 1, and a surface of the threaded rod 1 is threadedly connected to a threaded hole inside the adjustment module.

[0009] Preferably, a strip-shaped slot is provided on the surface of the column, the strip-shaped slot is communicated with the internal mounting slot of the column, and one end of the adjustment module is slidably disposed in the strip-shaped slot.

[0010] Preferably, a guide rod is installed inside the lifting arm, and the guide rod is inserted into the circular hole inside the moving module.
