Dedicated sling for concrete duct piece

Abstract

The invention discloses a dedicated sling for a concrete duct piece, which comprises a hand ring. The hand ring is fixed on a mounting plate; one end of a first hoisting and shrinking plate and one end of a second hoisting and shrinking plate are respectively connected to the mounting plate; the other end of the first hoisting and shrinking plate is connected with a first forceps holder; the other end of the second hoisting and shrinking plate is connected with a second forceps; a baffle is arranged inside the vertical tail end of the first forceps holder; a clamp is arranged inside the vertical tail end of the second forceps holder; and the horizontal end of the second forceps holder is arranged in the horizontal end of the first forceps holder in a penetrating manner to axially slide. According to the dedicated sling for the concrete duct piece, the duct piece which is under the horizontally-arranged state can be hoisted, a hoisting process is safe, simple and easy to realize, a great quantity of manpower and hoisting material can be saved, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to a hanger, in particular to a special hanger for concrete segments. Background technique [0002] In the production process of large-tonnage concrete segments, because the diameter of each ring segment is very large, some segments have a diameter of 10 meters and a weight of 15 tons, so lifting the segments is a very important link. For the hoisting of segments with a certain radian, there is no professional hoisting tool at present. The existing technology adopts manual operation, using hoisting or wire rope hoisting, but the disadvantage of this method is that it is necessary to manually install hoisting belts or wire ropes , which requires a lot of manpower; manual operation also has major safety hazards; during the hoisting process, it may cause damage to the edge of the segment and affect product quality. Contents of the invention [0003] The purpose of the present invention is to provide a special lifting tool for conc...
