Embodiment Construction
[0032] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0033] The present invention is an improvement of Chinese patent ZL 200520039691.2, which mainly includes a power transmission mechanism for driving the rotation of the propeller, a rotary control mechanism for controlling the rotation of the propeller and its power transmission mechanism, and a lifting mechanism for driving the rotary control mechanism, the power transmission mechanism, and the lifting of the propeller. mechanism, and a lift-type support mechanism matched with the lift mechanism.
[0034] The power transmission mechanism (see Figure 1) is composed of the main engine 3, the clutch 2, the upper gear box 1, the intermediate drive shaft 13 and the connecting sleeve 12, the lower gear box 16, the tail shaft sealing device 15, the bottom cover of the lower gear box 17, and the propeller 14 . There is an independent clutch 2 between the host ...

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 waterway ship, in particular to a rudder propeller device with an integral full rotation and a liftable lift. Background technique [0002] Chinese patent ZL200520039691.2 discloses an integral rotary lift type rudder paddle device, which mainly consists of a lifting platform installed at the stern, a hydraulic cylinder, a frame, an upper and lower gear box, a propeller, a connecting sleeve, a main engine, and a rotary mechanism and other components, the entire rudder paddle device can be driven by the slewing mechanism to make a rotation of less than or equal to 90 degrees left and right, and can also move up and down together with the lifting platform. Although the rudder paddle device of this structure solves the problem of the Z-type propulsion device The transmission efficiency is not high and the additional moment problem caused by the single cantilever structure, but because the support shaft...
