Abstract

The invention relates to the technical field of rudderstock nut lifting devices, in particular to a rudderstock nut lifting device, and solves the problems that a rudderstock nut lifting device adopted in the prior art cannot fix a nut in the lifting process, the stability of a tray is not enough when a chain hoist is used for lifting, and the nut and threads on the rudderstock are easily galled, scratched and even seized. The rudderstock nut lifting device comprises a fixed plate, two square pipes, a tray, a bearing and a rotating disc, the two square pipes are fixedly connected to the two sides of the fixed plate respectively, a limiting device is arranged on the surface of the rotating disc, the limiting device comprises a first screw rod, a second screw rod and a third screw rod, and the surfaces of the first screw rod, the second screw rod and the third screw rod are all rotationally connected with the rotating disc. According to the rudderstock nut lifting device, through the arrangement of the limiting device, the nut can be conveniently placed on the rotating disc, the nut and the rotating disc can be driven to be located on the same axis, and therefore labor input is reduced, and the operation is convenient.

Description

Technical field [0001] The present invention relates to the technical findings of a rudder nut, in particular, to a rudder nut lifting device. Background technique [0002] The rudder is the axis of the rudder, which is used to withstand and transmit the force and the helmet of the rudder and the force to the steering device, that is, the steering machine rotates the rudder leaf through the rudder rod, and the rudder leaf is subjected to water pair Its reaction force makes the ship to turn the ship, and the rudder nut lifting device is one of the important tools used in the lower part of the hydraulic nut in the shipyard. It is mainly used to position and stabilize the nut when the hydraulic nut is used to rotate the hydraulic nut of the rudder. Provides the upward support force to step into the rudder. [0003] Currently, the rudder nut lifting device cannot secure the nut during the lifting process, and when the manual hoist lifes, since the nut is not fixed, and the stability ...
