Embodiment Construction

[0018] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0019] Such as figure 1 , figure 2 As shown, the ladder 1 of the hydraulic boarding ladder according to the present invention is connected to the rotary base 5 through the rotation axis 5, and can rotate around the rotation axis 6; at the same time, it is connected to the piston 2 of the lifting hydraulic cylinder 3 at the connecting portion, The lifting hydraulic cylinder 3 is rotatably connected to the top surface of the revolving base 5 through the pivot 4; the telescopic action of the lifting hydraulic cylinder 3 can realize the rising and falling swing of the ladder 1.

[0020] Such as image 3 , Figure 4 As shown, an oil tank 102 and a pump station are arranged in the rotary base 5, and the rotary gear 103 is fixed on the base frame 104. The output shafts of the two hydraulic motors 101 are provided with a pinion 105, and the pi...

Abstract

The invention relates to a hydraulic boarding ladder. The ladder is connected to a rotating base by a rotating axis and simultaneously connected with the piston of an elevating hydraulic cylinder, and the elevating hydraulic cylinder is rotatably connected with the top surface of the rotating base by a pivot. Fuel tanks and a pump station are arranged in the rotating base, a rotating gear is fixed on the rotating base, pinion gears are arranged on the output shafts of two hydraulic motors, and the pinion gears are engaged with the rotating gear. In the invention, one pair of fuel tanks are connected with the main part of the boarding ladder, the boarding ladder is driven by the contraction and expansion of the fuel tanks to rise and fall, and the maximum rising and falling angle is + / -30 degrees; and the boarding ladder is driven by the clockwise and anticlockwise rotation of one pair of rotating motors to swing left and right, torsion is by transmitted by one pair of pinion gears and the rotating gear fixed on a base frame, and the swinging angle is about + / -180 degrees.

Description

technical field [0001] The invention relates to the field of marine equipment, in particular to a hydraulic boarding ladder. Background technique [0002] At present, most of the passenger boarding and disembarking ships in various coastal ports and wharves in my country use simple boarding ladders except the ship's own gangway. This boarding ladder often needs to be adjusted by a manual device to adjust the lifting height, and the degree of automation is very low. In addition, such a boarding ladder sometimes requires the aid of equipment such as a crane to be well connected with the cabin door of the ship, and there are certain potential safety hazards. At present, there are also hydraulic boarding ladder devices. The structure of these boarding ladders is not compact enough. In addition, the impact of wind and waves on the hull will cause the hull to float up and down, shake left and right, and comprehensively move up and down. The boarding ladders that appear at present...
