The invention aims to overcome the defects in the prior art and provides the aluminum alloy working stern platform ladder which is simple in structure, convenient to use, high in connection strength and high in safety.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the utility model provides an aluminum alloy work ship afterbody platform ladder, is equipped with the hull, and the hull rear side is equipped with the afterbody platform, its characterized in that the afterbody platform on be equipped with the ladder, the ladder include horizontal connecting rod, vertical connecting rod, step ladder pole, go up the engaging lug seat, go up the hinge, horizontal connecting rod establish on the afterbody platform, the front end of horizontal connecting rod is articulated mutually through last hinge with the last engaging lug seat that is equipped with on the afterbody platform, the rear end of horizontal connecting rod is connected with the upper end of vertical connecting rod is perpendicular, vertical connecting rod extend afterbody platform below, vertical connecting rod from bottom to top equipartition is equipped with step ladder pole, the middle part of step ladder pole is connected perpendicularly with vertical connecting rod and is the fishbone form, the ladder is accomodate to the afterbody platform on through last hinge rotation.
The rear end of the horizontal connecting rod is provided with a vertical baffle plate, the vertical baffle plate is vertically connected with the horizontal connecting rod, a lower connecting lug seat is arranged below the horizontal connecting rod on the front side of the vertical baffle plate and is hinged with the upper end of the vertical connecting rod through a lower hinge shaft, the vertical connecting rod is perpendicular to the horizontal connecting rod when in use through the vertical baffle plate, and the vertical connecting rod is horizontal to the vertical connecting rod when not in use through the lower connecting lug seat and the lower hinge shaft.
The rear end of the horizontal connecting rod is provided with a storage rope, one end of the storage rope is connected with the horizontal connecting rod, the other end of the storage rope extends to the ship body and is tied to the railing, and the storage of the ladder is achieved through the storage rope.
The anti-abrasion protruding layers are respectively arranged above the two sides of the step rod, so that the friction force of the step rod is increased.
Due to the adoption of the structure, the invention has the advantages of simple structure, convenient use, high connection strength, high safety and the like.

Fig. 3 is a side schematic view of the vertical links and the step bar of fig. 1.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in the attached drawing, an aluminum alloy work stern portion platform ladder is equipped with hull 1, and 1 rear side of hull is equipped with afterbody platform 2, its characterized in that afterbody platform 2 on be equipped with the ladder, the ladder include horizontal connecting rod 3, vertical connecting rod 4, step pole 5, go up engaging lug seat 6, go up hinge 7, horizontal connecting rod 3 establish on afterbody platform 2, the last engaging lug seat 6 that is equipped with on horizontal connecting rod 3's front end and afterbody platform 2 is articulated mutually through last hinge 7, the rear end of horizontal connecting rod 3 is connected perpendicularly with the upper end of vertical connecting rod 4, vertical connecting rod 4 extend afterbody platform 2 below, vertical connecting rod 4 from bottom to top equipartition is equipped with step pole 5, the middle part of step pole 5 is connected perpendicularly with vertical connecting rod 4 and is the fishbone form, the ladder is accomodate to afterbody platform 2 through last hinge 7 rotation.
Further, the rear end of horizontal connecting rod 3 be equipped with vertical baffle 8, vertical baffle 8 is connected with horizontal connecting rod 3 is perpendicular, horizontal connecting rod 3 below of the front side of vertical baffle 8 be equipped with down connect the ear seat 9, connect the ear seat 9 down and articulate mutually through the upper end of hinge 10 and vertical connecting rod 4 down, make vertical connecting rod 4 perpendicular with horizontal connecting rod 3 when using through vertical baffle 8, through connect ear seat 9 and hinge 10 down make vertical connecting rod 4 accomodate state and vertical connecting rod 4 level when not using.
Further, the rear end of the horizontal connecting rod 3 is provided with a storage rope 11, one end of the storage rope 11 is connected with the horizontal connecting rod 3, the other end of the storage rope extends to the ship body 1 and is tied on a railing 13, and the storage of the ladder is realized through the storage rope 11.
Furthermore, the upper parts of the two sides of the step ladder rod 5 are respectively provided with an anti-abrasion protruding layer 12, so that the friction force of the step ladder rod 5 is increased.
When the invention is used, the ladder stored on the tail platform 2 is released, the vertical connecting rod 4 and the step rod 5 are released to the side surface of the tail platform 2, the vertical connecting rod 4 is hinged with the horizontal connecting rod 3, the vertical connecting rod 4 cannot incline towards the outer side because the vertical connecting rod 4 is shielded by the vertical baffle 8, meanwhile, the inner side of the vertical connecting rod 4 is shielded by the tail platform 2 and cannot incline towards the inner side, a person climbs above the tail platform 2 through the step rod 5, when the invention is not used, the ladder is pulled above the tail platform 2 through the storage rope 11 to further realize storage, the vertical connecting rod 4 and the horizontal connecting rod 3 are hinged with each other, therefore, the vertical connecting rod 4 can be folded into a horizontal shape to further realize storage, the storage rope 11 is only used for storage function because of labor is wasted in the storage process, the ladder release can be released through artificially entering the tail platform 2, which is simple and rapid, due to the adoption of the structure, the invention has the advantages of simple structure, convenient use, high connection strength, high safety and the like.
