Problems solved by technology

When the hydraulic nut is pre-installed in the field, it needs to be hoisted horizontally to the installation position before assembly. However, the hydraulic nut lacks a suitable lifting point. Generally, a steel wire rope is used to pass through the nut. After the hydraulic nut is coaxial with the stud, it is rotated. The nut is screwed into the stud, this kind of hoisting is unstable, and it is difficult to adjust the coaxial

Abstract

The invention discloses a tool for ship hydraulic nuts for horizontal lifting. The tool comprises a lifting plate, and a first lifting lug arranged on the lifting plate; lifting columns are symmetrically arranged on the lower surface of the lifting plate about the axis of the lifting plate; and bearing bolts matched with mounting holes on the outer walls of the hydraulic nuts are arranged at the tail ends of the lifting columns. The bearing bolts symmetrically arranged on the tool are inserted in the original mounting holes on the outer walls of the hydraulic nuts; the bearing bolts are connected with the lifting plate through the lifting columns; the first lifting lug is connected with the lifting plate; and lifting machinery is connected with the first lifting lug to directly perform horizontal lifting of the hydraulic nuts, so that the horizontal lifting stability of the hydraulic nuts is improved.

Description

technical field [0001] The invention relates to the technical field of hoisting tooling, in particular to a tooling for horizontally hoisting marine hydraulic nuts. Background technique [0002] There are many hydraulic nuts in the ship rudder shaft system, and the hydraulic nuts are generally large in size and heavy in weight, which can reach thousands of tons. When the hydraulic nut is pre-installed in the field, it needs to be hoisted horizontally to the installation position before assembly. However, the hydraulic nut lacks a suitable lifting point. Generally, a steel wire rope is used to pass through the nut. After the hydraulic nut is coaxial with the stud, it is rotated. The nut is screwed into the stud. This kind of hoisting is unstable and it is difficult to adjust the coaxial. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art and provide a tool for horizontally hoisting marine hydraulic nuts with s...
