The upper end face of the mounting disc is symmetrically provided with two pairs of lifting lugs. Four supporting columns are symmetrically welded to the two sides of the lower end face of the mounting disc. The tail ends of the four supporting columns are provided with four mounting circular rings respectively. The four mounting circular rings are arranged on four rotating shafts through bearings respectively. The four rotating shafts are fixedly arranged on two grabbing branch chains opposite to each other. Two lug bases are symmetrically welded to the two sides of the lower end face of the mounting disc. Two first hydraulic cylinders are arranged on the two lug bases through pin shafts respectively. Telescopic rods of the two first hydraulic cylinders are arranged on two sleeves through threads respectively. The two sleeves are arranged on two supporting blocks through bolts respectively.
