AI Technical Summary
The existing core frame smooth lifting device suffers from a lack of synchronization between the left and right hydraulic cylinders, resulting in a large load on the intermediate bearing, which is prone to bending, deformation, or breakage.
It adopts a single hydraulic cylinder structure, which is connected to the axial rotation mechanism through the inner and outer swing arms. One end of the hydraulic cylinder is fixed on the base, and the other end is connected to the connecting arm. The inner and outer swing arms realize the smooth lifting and lowering of the working platform under the push of the hydraulic cylinder, avoiding the mutual jamming caused by the two hydraulic cylinders being out of sync.
This achieves smooth lifting and lowering of the core frame, avoiding bending deformation and breakage of the intermediate shaft, and improving the stability and reliability of the device.
