Marine hydraulic steering gear electric control device

Abstract

The invention discloses an electric operating device for marine hydraulic steering gear, which relates to the technical field of shipbuilding; it includes a hand wheel and a rotating shaft, one end of the rotating shaft is connected with the hand wheel, the other end is connected with the shaft of a universal transfer switch, the first rotating shaft seat is connected with the second One side of the rotating shaft seat is connected, and the other side of the second rotating shaft seat is connected with the universal switch. An elliptical cam is set on the rotating shaft passing through the second rotating shaft seat, and the elliptical cam is in contact with the top wheel. In the wheel seat, springs are arranged on both sides of the top wheel, and a limit ring is set between one side of the elliptical cam and the second shaft seat; the limit ring is fixedly connected with the shaft, and the limit ring limits the rotation angle of the handwheel to ±44° °. The present invention can solve the problems that the electric operating device of the marine hydraulic steering gear is prone to failure, has poor reliability, and cannot automatically reset when the hand is released when the handwheel is turned.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an electric operating device for controlling a marine hydraulic steering gear. Background technique [0002] In the shipbuilding industry, the marine hydraulic steering gear is the equipment used to control the course of the ship. The steering wheel is equipped with an electric control device for controlling the marine hydraulic steering gear. An existing electric control device includes a handwheel, and one end is connected to the handwheel. 1. The other end is connected to the rotating shaft of the universal transfer switch; the rotating shaft passes through the deep groove ball bearings arranged on the first rotating shaft seat and the second rotating shaft seat; the rotating shaft is sleeved with a spring for torsion. The structure is relatively complicated, the processing is difficult, and there is only one spring, and the spring is stressed at one point, which often br...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a marine hydraulic rudder electric control device, which can solve the problem that the marine hydraulic rudder electric control device is prone to failure, poor reliability and when the hand is released when the hand wheel turns the rudder. It cannot be reset automatically, and the handwheel must be turned back by hand in order to cut off the power of the universal transfer switch and switch to the non-steering state.
