Abstract

The invention discloses a screw propeller folding device. The screw propeller folding device comprises an upper transmission box, a transmission shaft outer barrel, a lower transmission box, a screw propeller, a mounting frame, a sleeve, a positioning seat, a short shaft, a swivel arm, a hydraulic cylinder, a hydraulic cylinder seat, a steering rudder, a steering rudder seat, a liner bushing, an inhaul cable and bolts, wherein the upper transmission box, the transmission shaft outer barrel and the lower transmission box are fastened to form a whole body through the bolts; the screw propeller is fixedly arranged on an output shaft of the lower transmission box; rotary folding of the screw propeller can be realized through the hydraulic cylinder; the steering rudder can be controlled throughthe inhaul cable and horizontal steering is realized; the device disclosed by the invention has the advantages of scientific design, compact structure, reliable performance, convenience for mountingand dismounting and low cost; the screw propeller folding device can be mounted at the rear part of a vehicle in a folding manner, and ideal power and reliable steering can be provided for water-surface floating crossing of the vehicle.

Description

technical field [0001] The invention relates to a general hydraulic mechanical device, in particular to a propeller device which can provide power and reliable steering when the vehicle floats on the water surface, and is installed on the rear of the vehicle in a folded manner. Background technique [0002] At present, the amphibious vehicles manufactured both at home and abroad are equipped with fixed propellers and are all installed under the vehicle floor. Although this assembly method is simple in structure, it significantly reduces the ground clearance of the vehicle, thereby obviously affecting the passing performance of the vehicle on land, and its propeller is also prone to damage. Contents of the invention [0003] The purpose of the present invention is to provide a "propeller folding device" that is scientific in design, compact in structure, reliable in performance, convenient in loading and unloading, low in cost, and can be matched with various amphibious veh...
