1. the technical scheme of the invention can realize clamping and transferring of the hoisted object, and the transferring direction can be flexibly adjusted.
2. In the process that the transfer system clamps the hoisted object, each clamping and positioning motor respectively drives the clamping movable ring bodies arranged up and down to rotate at different angles along the clamping fixed cavity so as to realize that the corresponding clamping frames are respectively inserted into the clamping holes of the hoisted object which are staggered up and down; the dangerous situation that the hoisted object is stressed too intensively on a certain transverse surface or vertical surface to be damaged is avoided.
3. The encoders in the transfer system are respectively used for detecting that each clamping moving ring body rotates by an even interval angle, and the clamping detection photoelectric switch is used for detecting whether the clamping frame is aligned with the clamping holes or not; after the encoder detects that the clamping movable ring body rotates by an optimal angle, if the clamping detection photoelectric switch detects that the clamping frame is not aligned with the clamping hole of the hoisted object, the clamping positioning motor can be used for rotating and fine-adjusting to accurately position the nearest clamping hole.
4. In order to facilitate the clamping frame to enter and exit the clamping hole of the hoisted object, the diameter of the clamping frame is smaller than that of the clamping hole; when the clamping frame enters the clamping hole, the clamping adjusting oil cylinder drives the clamping driving oil cylinder to move upwards, and when the pressure sensor detects that the pressure reaches a certain value, the upper end of the clamping frame is proved to be clamped and fixed with the clamping hole.
