A kind of lifting tool and hoisting method for vertical shaft connection of rod and wire

Abstract

The invention relates to the technical field of lifting tools, in particular to a rod and wire vertical type connecting shaft lifting tool and a lifting method thereof. According to the technical scheme, the lifting tool comprises a hanging beam, two clamping plates and two adjusting assemblies. Multiple lifting lugs are symmetrically arranged on the top wall of the hanging beam, and the multiplelifting lugs are provided with open holes allowing a traveling crane to be arranged in a hung manner. The two clamping plates are arranged at the two ends of the hanging beam separately. The multipleadjusting assemblies penetrate through the side walls of the two clamping plates separately, the ends, away from the hanging beam, of the adjusting assemblies are connected with locking chains, the locking chains are arranged at the ends of the adjusting assemblies in an unrolled manner, locking holes allowing objects to penetrate through are formed in the middles of the locking chains, and the adjusting assemblies are used for adjusting the opening sizes of the locking holes. The invention further provides a hoisting method of the rod and wire vertical type connecting shaft lifting tool. Therod and wire vertical type connecting shaft lifting tool and the lifting method thereof have the beneficial effects of being simple and reasonable in structure, convenient to operate and wide in application range.

Description

technical field [0001] The present invention relates to the technical field of a hoisting tool, more specifically, it relates to a hoisting tool and a hoisting method for a vertically connected shaft for rods and wires. Background technique [0002] At present, the bar and wire production line is equipped with a vertical rolling mill due to the production process requirements. The vertical connecting shafts connected to the gearbox of the vertical rolling mill and the rolling mill rolls are all disassembled vertically. Due to the different specifications of the vertical rolling mills, the used The shaft diameter or type of the vertical shaft is different. When disassembling the vertical shaft, the commonly used tool is the lifting tool. [0003] At present, hoisting tools are generally composed of hanging beams, lifting lugs, counterweights and hoops. The hanging beams are elongated. A counterweight is installed at one end of the hanging beam, and a hoop is set at the other ...
