Integral full turning lift type steering oar device

Abstract

The invention relates to an integrally full-revolving and lifting rudder paddle device, including a power actuating mechanism, a rotation control mechanism, a lifting mechanism and a lift type supporting mechanism which engages with the lifting mechanism. The invention is characterized in that the lift type supporting mechanism is a thrust stand composed of sleeves, a stempost, a lifting slide bar, a connection board and a thrust plate, the sleeves are arranged on both sides of the propeller screw and the U-typed groove on the stem in two groups, the upper end of the sleeves is fixed with the stem and the lower end is fixed with the stempost, two groups of lifting slide bars penetrate the two groups of sleeves, the upper end is detachably connected with lift platform via a connection plate, the lower end is connected with the thrust plate. The power actuating mechanism penetrates the U-typed groove of the stem, a supporting axis arranged at the lower end of the power actuating mechanism is rotationally connected with the thrust plate and the whole propeller screw can rotate with a degree of 360 DEG in the thrust stand. The rudder paddle device has the advantages that the propeller screw can rotate with a degree of 360 DEG, the lift range of the propeller screw is large and the ship needs no ballasting when navigating with no load.

Description

Technical field [0001] The invention relates to a power device for an inland watercraft, in particular to a rudder propeller device that can be raised and lowered in an integral full rotation. Background technique [0002] Chinese patent ZL 200520039691.2 discloses an integral rotary lift type rudder propeller device, which is mainly composed of a lifting platform installed on the stern of the ship, a hydraulic cylinder, a frame, an upper and lower gear box, a propeller, a connecting sleeve, a main engine, a slewing mechanism, etc. The whole rudder propeller device can be rotated by less than or equal to 90 degrees on the left and right under the drive of the slewing mechanism, and it can also move up and down with the lifting platform. This structure of the rudder propeller device solves the problem of the Z-type propulsion device transmission The problem of additional torque caused by low efficiency and single cantilever structure, but because the support shaft on the lower gea...
