Abstract
The utility model relates to an aluminum alloy boarding ladder which comprises an inclined ladder disposed between a dock and the deck of a ship. The aluminum alloy boarding ladder is characterized by further comprising a bridging slab, two parallel parallelogram hinge mechanisms and a base plate. The bridging slab is hinged to the upper end of the inclined ladder and rested on the deck of the ship. A hinge shaft is parallel with the extending direction of the ship. The two parallelogram hinge mechanisms are located on the left side and the right side of the inclined ladder. Two lateral edges of the inclined ladder respectively form the inclined edges of the two parallelogram hinge mechanisms. The base plate is fixed to the lower bottom edges of the two parallelogram hinge mechanisms and can move along the left and right and front and back directions of the ship relative to the dock. The aluminum alloy boarding ladder is light, easy to carry, and widely applicable to various ships, and ship shifting and height difference caused by tides, winds and waves can be neutralized.
Description
Technical field
The utility model relates to boarding ladder, is specifically related to a kind of aluminum alloy boarding ladder.
Background technology
Between boats and ships and harbour, often carry out the exchange of personnel and goods, boarding ladder is exactly for connecting the passage between boats and ships and harbour.The workplatform on boats and ships is fixed in boarding ladder one end, and the other end and harbour bank are fixed.But along with the fluctuation of tidewater, the height of boats and ships constantly changes; Along with the impact of stormy waves, can there is the drift of front and back or left and right in boats and ships near stop position.The boarding ladder of prior art is subject to above-mentionedly affect rear easy generation distortion and have potential safety hazard.Boarding ladder often selects steel or stainless steel to make, and it carries inconvenience, and owing to resting in the different boats and ships height differences of harbour, the general applicability of boarding ladder is poor.
Utility model content
The utility model product, for the deficiencies in the prior art, provides a kind of aluminum alloy boarding ladder, and not only lightweight is portable, can also dissolve the boats and ships drift and the height fall that because of tidewater and stormy waves, cause, and good for various boats and ships applicabilities.
In order to solve the problems of the technologies described above, the utility model product is achieved through the following technical solutions:
A kind of aluminum alloy boarding ladder, comprise the inclined ladder being arranged between harbour and ship deck, it is characterized in that, also comprise attachment strap, two parallelogram linkages that are parallel to each other and base plate, described attachment strap and inclined ladder upper end chain connection, be erected on ship deck, hinge axis is parallel to the bearing of trend of hull; Two parallelogram linkages are positioned at the left and right sides of inclined ladder, and the dual-side of inclined ladder forms respectively the hypotenuse of two parallelogram linkages; The bottom of described base plate and two parallelogram linkages is fixed, can be with respect to the displacement of harbour generation left and right directions and fore-and-aft direction.
As a kind of embodiment, also comprise slide rail and roller, described base plate is arranged on described slide rail, can on slide rail, horizontally slip; Described roller is fixed on the bottom of described slide rail, makes the slide rail can scroll forward and backward.
Preferably, the upper base of described attachment strap and two parallelogram linkages is positioned at same plane.
Further, the hinge axis of two parallelogram linkages is all parallel to the bearing of trend of hull.
Preferably, the two ends, left and right of described slide rail are also provided with the limiting device that the described base plate of restriction skids off slide rail.
Further, described inclined ladder comprises the dual-side being parallel to each other and a plurality of steps that are connected dual-side.
Further again, described inclined ladder also comprises the guard rail that is arranged at dual-side.
Aluminum alloy boarding ladder of the present utility model, adopts aluminum alloy material to make, the portable and carrying of lightweight; Due to the setting of two parallelogram linkages, can be used for dissolving height fall and the left and right drift of boats and ships; And bottom roller the front and back drift that can dissolve boats and ships is set.The aluminum alloy boarding ladder life-span of the present utility model is extended, and safer, and the boats and ships that are applicable to differing heights use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The implication that each Reference numeral represents is:
1-hull, 2-harbour, 3-attachment strap, 4-inclined ladder, 41-side, 42-step, 5-base plate, 6-slide rail, 7-limiting device, 8-roller, 9-parallelogram linkage, the upper base of 91-, 92-bottom, 93-hypotenuse, 10-ship deck.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, aluminum alloy boarding ladder of the present utility model, comprises inclined ladder 4, attachment strap 3, two parallelogram linkages 9, base plate 5, slide rail 6, limiting device 7 and rollers 8.In general, when hull 1 rests against harbour 2, the bearing of trend of hull is parallel with harbour bank.
Inclined ladder 4 is arranged between harbour 2 and ship deck 10, and attachment strap 3 and inclined ladder 4 upper end chain connections, be erected on ship deck 10, and this hinge axis is parallel with the bearing of trend of hull.
Inclined ladder 4 comprises the dual-side being parallel to each other, a plurality of steps that connect dual-side and the guard rail that is arranged at dual-side.
The bottom 92 of base plate 5 and two parallelogram linkages 9 is fixing, and base plate 5 is arranged on slide rail 6, and roller 8 is fixed on the bottom of slide rail 6.Using the bearing of trend of hull 1 as fore-and-aft direction, and base plate 5 can horizontally slip on slide rail 6 so, slide rail 6 can be on quay surface scroll forward and backward.Preferably, the two ends, left and right of slide rail 6 are also provided with limiting device 7, in case base plate 5 skids off slide rail 6.
Aluminum alloy boarding ladder of the present utility model material used is all selected aluminum alloy material, has realized the more lightweight of boarding ladder, is easy to carry or carries.
The utility model in use, is overlapped on attachment strap 3 on ship deck 10, along with the fluctuation of tidewater, and the replacing of different boats and ships, can adjust freely the leaning angle between inclined ladder 4 and hull 1.As the left and right drift of hull 1, can carry out the adjustment of position, left and right by base plate 5; As the front and back drift of hull 1, can on quay surface, carry out by slide rail 6 adjustment of front and back position.
Finally it should be noted that: these are only preferred embodiment of the present utility model; be not limited to the utility model; although the utility model is had been described in detail with reference to embodiment; for a person skilled in the art; its technical scheme that still can record previous embodiment is modified; or part technical characterictic is wherein equal to replacement; but all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
