Hoisting equipment

Abstract

The invention relates to the technical field of hoisting, and provides hoisting equipment. The hoisting equipment comprises a hoisting beam assembly, a positioning assembly and a tensioning assembly. The hoisting beam assembly can do linear reciprocating motion in the vertical direction. The positioning assembly is arranged on the lower side of the hanging beam assembly and comprises a first positioning piece and a second positioning piece, the second positioning piece is used for being detachably arranged on the outer cylinder, one of the first positioning piece and the second positioning piece forms a plug pin, and the other one of the first positioning piece and the second positioning piece forms an insertion hole; the bolt is inserted into or separated from the jack along the vertical direction; the tensioning assembly is arranged on the lower side of the positioning assembly and comprises a soft friction block, and the soft friction block is used for abutting against the inner wall face of the inner cylinder; the lifting beam assembly drives the tensioning assembly to ascend, so that the tensioning assembly drives the inner barrel to ascend. The bolt is inserted into the jack along the vertical direction to realize initial centering; the soft friction blocks abut against the inner wall face of the inner cylinder, the soft friction blocks can deform adaptively, and self-adaptive supporting is achieved.
