Abstract
The invention relates to a revolving mechanism of a hydraulic pressure boarding ladder. A ladder is connected on a revolving base by a rotating axis and is connected to a piston of a lifting hydraulic cylinder at the meantime, and the lifting hydraulic cylinder is rotatably connected to the top surface of the revolving base by a pivot; an oil box and a pump station are arranged in the revolving base, a revolving gear is fixed on the revolving base, small pinions are arranged on the output shafts of two hydraulic motors, and each pinion is meshed with the revolving gear. In the invention, a pair of oil cylinders is adopted to be connected with the main part of the boarding ladder, the ascending and descending of the boarding ladder are driven by stretching of the oil cylinder, and the maximum angle for ascending and descending is plus/minus 30 degrees; and the torque is transmitted via a pair of the pinions and the revolving gears fixed on a base frame by virtue of alternating rotation of a pair of the revolving motors, so as to drive the boarding ladder to swing left and right, and the swing angle is about plus/minus 180 degrees.
Description
Technical field
The present invention relates to the marine equipment field, especially the swing type mechanism of hydraulic pressure boarding ladder.
Background technology
The upper and lower steamer of passenger major part except that steamer carries gangway ladder adopts easy boarding ladder in coastal each port and pier of China at present, and this boarding ladder often needs to regulate adjustable height with manual setter, and degree of automation is very low.In addition, this boarding ladder also need could well dock with the steamer hatch door by means of equipment such as hoisting cranes sometimes, and has certain potential safety hazard.The boarding ladder device that adopts hydraulic pressure is also arranged at present.The structure of these boarding ladders is compact inadequately, in addition stormy waves to the influence of hull can make hull have up and down float and about rock and up and down integrated motion, the boarding ladder that occurs can only to a certain degree be accomplished to fluctuate with stormy waves at present, and this obviously can not adapt to complicated ship motion situation; Therefore the range of use of this boarding ladder is narrow and small, especially can not use for marine operation at all.
Summary of the invention
The applicant is low at above-mentioned existing boarding ladder degree of automation, structure is compact inadequately, can not adapt to complicated shortcomings such as ship motion situation, a kind of swing type mechanism of hydraulic pressure boarding ladder rational in infrastructure is provided, thereby can satisfy complicated applied environment needs, realization fluctuates and these two actions of double swerve, thereby guarantees equipment and personnel's stability and safety.
The technical solution adopted in the present invention is as follows:
A kind of swing type mechanism of hydraulic pressure boarding ladder, ladder is connected on the revolution pedestal by pivot center, is connected with the piston of lifting hydraulic cylinder simultaneously, and described lifting hydraulic cylinder is by the rotatable revolution base top surface that is connected of pivot; Be provided with fuel tank and pumping plant in the revolution pedestal, swiveling gear is fixed on the revolution pedestal, and two hydraulic motor output shaft are provided with miniature gears, and miniature gears is meshed with swiveling gear.
The present invention adopts a pair of oil cylinder to be connected with the boarding ladder base portion, the rising and the decline of stretching and driving boarding ladder of utilization oil cylinder, and wherein the maximum angle of rise and fall is positive and negative 30 degree; Control for angle can be determined with the particular case that is connected height of boarding ladder with the oil cylinder earrings by the stroke of oil cylinder piston bar.The present invention adopts the rotating of a pair of rotary motor, by a pair of miniature gears and the swiveling gear transfer torque that is fixed on the pedestal, drives swinging of boarding ladder, and pendulum angle is about positive and negative 180 degree.

Fig. 2 is the upward view of Fig. 1.
Fig. 3 is a cutaway view of the present invention.
Fig. 4 is the birds-eye view of Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, the ladder 1 of hydraulic pressure boarding ladder is connected on the revolution pedestal 5 by pivot center 5, can be around pivot center 6 rotations; Be connected with the piston 2 of lifting hydraulic cylinder 3 at connecting portion simultaneously, and lifting hydraulic cylinder 3 is by pivot 4 and rotatable revolution pedestal 5 end faces that are connected; The expanding-contracting action of lifting hydraulic cylinder 3 can be realized rising, the decline swing of ladder 1.
As shown in Figure 3, Figure 4, be provided with fuel tank 102 and pumping plant in the revolution pedestal 5, swiveling gear 103 is fixed on the pedestal 104, the output shaft of two HM Hydraulic Motor 101 is provided with miniature gears 105, miniature gears 105 is meshed with swiveling gear 103, and HM Hydraulic Motor 101 can realize the left rotation and right rotation of boarding ladder when rotating.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
