Abstract
The invention provides an autonomous lift articulated ladder comprising an eye plate, an articulated ladder body, a roller, a winch, a steel cable and a pulley. The inner extension end of the articulated ladder body is in hinge joint with a ship board deck through the eye plate and the bottom of the outer extension end is provided with the roller. The upper portion of the outer extension end of the articulated ladder body is provided with the winch. The winch is fixedly connected with one end of the matching steel cable, and the other end of the steel cable is fixedly connected to the outer extension end of the articulated ladder body through diversion of the pulley in hinge joint with an upper layer slipway. Thus, a mechanism that the winch and the steel cable cooperatively control the articulated ladder body to swing up and down with the eye plate as the axis is formed. A ship is provided with an articulated ladder and the release position or the release height can be autonomously adjusted in a permitted swing angle range according to working conditions; owing to the great adjustability and timeliness, reliable building is facilitated; the stable articulated ladder can greatly improve the sense of safety of passage of workers.
Description
Technical field
The present invention relates to a kind of ship deck machinery, specifically, when the present invention relates to a kind of vessel berth harbour, supply staff to step on the hinge ladder of disembark.
Background technology
During big-and-middle-sized cargo ship mooring wharf, because gun wale has several ten meters long at a distance of harbour, add deck and quay surface exists diff-H, step on disembark for the ease of staff, between ship and harbour, usually set up one be commonly called as temporary access road into " springboard ".In reality, various places harbour aims at the supporting temporary access road of big-and-middle-sized cargo ship is that a kind of hinge is terraced, and this terraced structure is simple, lifting is convenient, erection is easy, can meet the current requirement that personnel step on disembark under normal circumstances completely.But the hinge ladder of prior art is not equipped with power, when building by harbour side with crane hinge ladder handling to destination locations.For ship, this kind of passive hinge ladder of building is except lacking initiative and flexible activity, maximum problem is along with loading/unloading volume change, shipping draft also changes thereupon, add Lidar Equation and tidal fluctuations, easily cause the hinge ladder built on harbour and ship side deck to rock with hull.The hinge ladder position of building is unstable, certainly will increase the current difficulty that personnel step on disembark, also reduce current safety simultaneously.
Summary of the invention
The present invention, mainly for the deficiencies in the prior art, proposes a kind of autonomous lifting mode hinge ladder be configured on big-and-middle-sized cargo ship deck, and ship can build position, to improve stability and safety according to hull real-time working condition from main regulation hinge ladder.
The present invention is achieved through the following technical solutions technical goal.
Autonomous lifting mode hinge ladder, it comprises eye plate, hinge ladder, roller, winch, cable wire and coaster.Described hinge ladder is strip framing member, and inner extending end is hinged by eye plate and ship side deck, is provided with roller bottom overhanging end.Its improvements are: described hinge ladder overhanging end top is furnished with winch, cable wire one end that winch connects through upper strata building berth be hinged coaster turn to after connecting hinge chain ladder overhanging end, form winch and cable wire coordinate control hinge ladder with eye plate be axle swing up and down structure.
In said structure, winch is electric winch, and control hinge ladder overhanging end relative level line by winch and swing up and down, its pivot angle descends 30 on a horizontal
0regulate arbitrarily in angular range.
The present invention compared with prior art, has following good effect:
1, on hinge ladder, be equipped with engine installation simple, make easily;
2, hinge ladder provided for oneself by boats and ships, and can discharge position or height according to operating mode autonomous adjustment within the scope of license pivot angle, because adjustability is good and timely, be conducive to accomplishing reliably to build, pulsation-free hinge ladder significantly promotes sense of security when staff passes through.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention, and the hinge ladder in figure is horizontal.
Fig. 2 be hinge ladder in Fig. 1 overhanging end on pendulum 30
0the schematic diagram of angle.
Fig. 3 is the overhanging end bottom 30 of hinge ladder in Fig. 1
0the schematic diagram of angle.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Autonomous lifting mode hinge ladder shown in the drawings is on supporting platform maintenance ship, and it comprises eye plate 1, hinge ladder 2, roller 3, winch 4, cable wire 5 and coaster 6.Described hinge ladder 2 is strip framing member, and the hinge ladder 2 of the present embodiment hinge ladder shown in 2 long 18.35m, Fig. 1 is horizontal shape, and left end is inner extending end, and this end is hinged by eye plate 1 and ship side deck 7.Right-hand member is overhanging end, and when building, overhanging end extends Dock Target position, for the present situation that hull rocks with stormy waves, is provided with roller 3, rolls and can improve the contact quality of hinge ladder 2 overhanging ends and quay surface bottom hinge ladder 2 overhanging ends.The present invention is furnished with winch 4 on hinge ladder 2 overhanging end tops, described winch 4 is electric winch, winch 4 is fixedly connected with one end of supporting cable wire 5, cable wire 5 other end is fixedly connected on the overhanging end of hinge ladder 2 after the coaster 6 that upper strata building berth is hinged turns to, and formation winch 4 and cable wire 5 coordinate the luffing mechanism that control hinge ladder 2 is axle with eye plate 1.Consider from safe passing angle, the pivot angle relative level line upper and lower 30 of swinging gear
0comparatively suitable.The ladder of hinge shown in Fig. 12 is in Realize, and this situation is ideal position, and in fact ship side deck 7 and quay surface exist diff-H, actual when building hinge ladder 2 have certain pivot angle, it on, as shown in Figure 2, bottom end position is as shown in Figure 3 for pendulum end position.The hinge ladder 2 built in this angular range is convenient to staff and is passed through.Hinge ladder 2 provided for oneself by boats and ships, and can discharge position or height according to operating mode autonomous adjustment within the scope of license pivot angle, because adjustability is good and timely, be conducive to accomplishing reliably to build, pulsation-free hinge ladder 2 significantly promotes sense of security when staff passes through.
The present invention is except providing for oneself except walkway as big-and-middle-sized vessel berth harbour, and the walkway can also docked with offshore platform as big-and-middle-sized boats and ships, its effect is identical with above-described embodiment.
