Description
Technical field
The utility model relates to a kind of ship deck machinery, and specifically, the utility model relates to a kind of wharf ladder being arranged on gun wale, particularly a kind of displacement type wharf ladder.
Background technology
Kiloton boats and ships, naval vessel because of hull relatively large, drinking water is relatively dark, a gun wale and harbour segment distance apart when making harbour, and is usually discharged by ship and provides wharf ladder to step on disembark passage as staff for oneself.The wharf ladder of prior art is integral structure, is directly hinged and connected on ship side deck.This direct connection structural rigidity foot, good stability, on the quarter below deck 30
0in scope, reliable erection, can guarantee that staff steps on the current safety of disembark.However, there is limitation in actual use in prior art products, and namely or ship side deck equal with quay surface, ship side deck can normally use higher than during quay surface.Once shipful, ship side deck may lower than quay surface, this situation exceeds the wharf ladder erection scope of prior art, wharf ladder external part ladder rests on quayside, easily cause that to stretch to harbour one end roller down unsettled, and the ladder of wharf ladder directly directly contacts with quayside, because hull is with sea sloshing, dynamic wharf ladder is produced with static quayside junction rub, rub except generation noise, greatest problem causes the damage of wharf ladder and quayside, brings unnecessary dispute and economic loss thus.
Utility model content
The utility model is mainly for the little problem of prior art products variable range, propose a kind ofly to utilize the parallel four continuous lever mechanisms displacement type wharf ladders made of interlock principles, this terraced structure is simple, connect reliable, displacement processing ease, use safety and applied widely.
The utility model is achieved through the following technical solutions technical goal.
Displacement type wharf ladder, it comprises handrail, perpendicular railing, connecting rod, handle, pile and ladder.Described handrail and ladder are rod member, are hinged between the two by the contour and perpendicular railing of parallel spaced-apart, form the harbour ladder of likeness in form parallel four-bar linkage.Ladder overhanging end is provided with roller down, the handrail overlap joint handle overhanging towards hull direction, the handle suspended wall end overhanging along handrail is provided with clump weight, is hinged connecting rod in turning down at the handle other end, adjacent and the parallel spaced-apart of railing is erected on sagging connecting rod and the right, and connecting rod bottom and ladder are hinged.Its improvements are: described pile is vertically fixedly connected with on the quarter on deck, eye plate is respectively equipped with on pile top with at a distance of h=400 ~ 800mm place, ship side deck, handrail in harbour ladder and ladder reserved eye plate on hull one end and pile is hinged, form centered by the eye plate of harbour ladder on pile, relative ship side deck swings up and down structure.
In said structure, centered by the eye plate of harbour ladder on pile, relative ship side deck swings up and down, its pivot angle α=-30
0~ 30
0.Piles column bottom is provided with marks time, and marks time and is positioned at h1/2 place on ship side deck.Pile is provided with the locking bail of hand power screw structure, and this locking bail is used for when displacement type wharf ladder is collected spacing.
The utility model compared with prior art, has following good effect:
1, like the harbour ladder of parallel four continuous lever mechanisms, structure is simple, making is easy;
2, the harbour ladder deformation being hinged structure is easy, adds by pile frame height harbour ladder, significantly strengthens displacement scope, reliably can set up under various working condition in tolerance band;
3, seemingly the harbour ladder of parallel four continuous lever mechanisms, under the power-assisted of clump weight, manipulates laborsaving, quick;
4, like the harbour ladder easy-to-collection of parallel four continuous lever mechanisms, during collection, mechanicalness locking is done, good reliability with locking bail.

Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Displacement type wharf ladder shown in Fig. 1 is the embodiment of supporting 8 kiloton bulge carriers, and it comprises handrail 1, perpendicular railing 2, connecting rod 3, handle 4, pile 5 and ladder 6.Described handrail 1 and ladder 6 are rod member, and handrail 1 is positioned on ladder 6, are hinged between the two by the contour and perpendicular railing 2 of parallel spaced-apart, form the harbour ladder like parallel four-bar linkage.Ladder 6 overhanging end is provided with roller 6.1 down, and roller 6.1 effect improves the contact with quay surface 8.Handrail 1 is towards one end overlap joint handle 4 in hull direction, and handle 4 cantilever end overhanging along handrail 1 is provided with clump weight 4.1, and the clump weight 4.1 added plays balance and power-assisted effect in the structure, is conducive to alleviating manipulation force, improves erection efficiency.Be hinged connecting rod 3 in turning down at handle 4 other end, railing 2 adjacent and parallel period is erected on sagging connecting rod 3 and the right, and connecting rod 3 bottom and ladder 6 are hinged formation link gear.The utility model is vertical fixing pile 5 on deck 7 on the quarter, is respectively equipped with eye plate, h=500mm in the present embodiment on pile 5 top with at a distance of the h place on ship side deck 7.Handrail 1 in harbour ladder and ladder 6 reserved eye plate on hull one end and pile 5 is hinged, and form centered by the eye plate of harbour ladder on pile 5, swing up and down structure relative to ship side deck 7, this swings up and down pivot angle α=-30 of structure
0~ 30
0various working condition can be met completely in this angular range under, on the quarter 7 to quay surface, deck 8 sets up displacement type wharf ladder reposefully, guarantee that the ladder 6 of displacement type wharf ladder does not rest on quay surface 8 or quayside, even if hull rocks with stormy waves, barrel shift is only made in displacement type wharf ladder and quay surface 8, does not mutually produce destructive contact.Displacement type wharf ladder shown in Fig. 1 is in level erection, this situation pivot angle α=0
0, be convenient to personnel most and pass through.The embodiment that displacement type wharf ladder shown in Fig. 2 sets up under another kind of limiting condition condition, namely ship side deck 7 is higher than quay surface 8, and displacement type wharf ladder is in-30
0tilting erection, descending structure makes roller 6.1 can move with ladder 6 and rolls, the embodiment of setting up under another limiting condition condition of the displacement type wharf ladder shown in Fig. 3, namely ship side deck 7 is far below quay surface 8, the utility model increases the setting height(from bottom) of harbour ladder by pile 5, with the harbour ladder adopted like parallel four-bar linkage, although displacement type wharf ladder is with 30
0during tilting erection, quay surface 8 does not contact with ladder 6, and both are contacted by roller 6.1, and destructive contact does not occur thus.Because harbour ladder is high by pile 5 frame, pass through, be provided with and mark time 5.2 bottom pile 5 for the ease of personnel, marking time 5.2 is positioned at h1/2 place on ship side deck 7, i.e. 250mm place.During boats and ships departure, displacement type wharf ladder must be recovered on ship side deck 7 and collect, the utility model utilizes the harbour ladder seemingly folding principle of parallel four-bar linkage, and bar handle 4 makes harbour ladder be folded into shape as shown in Figure 4.In order to reliable collection, the utility model adopts locking bail 5.1 lock-bit of hand power screw structure, and this kind of mechanical type lock-bit is reliable, safety.
