The invention discloses one kind can adjust automatically mark time horizontal wharf ladder, including pedal of going on board, the pedal of going on board is fixed above deck, the pedal lower right of going on board is provided with ascending stair pedal, it is connected between the ascending stair pedal and pedal of going on board by channel steel, be horizontally installed on the inside of the channel steel it is multiple mark time and multiple shafts, the channel steel and go on board and be all made of hinge connection between pedal and ascending stair pedal.The present invention adjusts the height of ladder by the way that idler wheel horizontally slips along landing ground, to adapt to different differences in height, save the workload that docker changes ladder, by rotating freely channel steel around marking time, so that marking time self can adjust and keep horizontality, to ensure that pedestrian steps on the comfort and safety of time of taking the opportunity.
Description
Technical field
The present invention relates to wharf ladder field, it is specifically a kind of can adjust automatically mark time horizontal wharf ladder.
Background technique
Wharf ladder is that one kind is usually concealed in ship side, and the used time releases side of a ship outer gunnel and is in tilted layout, for going ashore on personnel
Ladder.General wharf ladder, in use, when rivers and lakes flood tide or ebb, needs replacing the ladder of different length in harbour
Son, and ladder marks time angle as the variation of water level is also vary, the inconvenience for causing ladder to use and steps on and multiplies personnel's walking not
Safety.
Summary of the invention
The purpose of the present invention is to provide one kind can adjust automatically mark time horizontal wharf ladder, to solve to exist in the prior art
The problem of.
To achieve the above object, the invention provides the following technical scheme: one kind can adjust automatically mark time horizontal wharf ladder, packet
Pedal of going on board is included, the pedal of going on board is fixed above deck, and the pedal lower right of going on board is provided with ascending stair pedal, the ascending stair
It being connected between pedal and pedal of going on board by gangway ladder, the gangway ladder includes channel steel, and it is horizontally installed with and marks time on the inside of the channel steel, institute
It states channel steel and goes on board and be all made of hinge connection between pedal and ascending stair pedal.
Further, the channel steel includes that channel steel A, channel steel B, channel steel C and channel steel D, the channel steel A are located at the right channel steel B,
The channel steel B is located in front of channel steel C, and the channel steel C is located at the left channel steel D, and the channel steel D is located at the rear channel steel A, the channel steel
A, channel steel B, channel steel C and channel steel D are parallel to each other.
Further, described to mark time at least one, described mark time is connect between channel steel by shaft.
Further, the front/rear end marked time is respectively fixed with two unthreaded hole lantern rings, and the shaft passes through unthreaded hole set
Ring.
Further, the both ends of the shaft is provided with screw thread, and screw thread is located at the outside of channel steel.
Further, ascending stair pedal bottom is equipped with idler wheel.
Further, handrail is installed on the channel steel A and channel steel D.
Compared with prior art, the beneficial effects of the present invention are: the present invention by by idler wheel along landing ground horizontally slip come
The height for adjusting ladder saves the workload that docker changes ladder to adapt to different differences in height, by setting in both ends of the shaft
Screw thread is set, the fixation and disassembly marked time is facilitated and can self so that marking time by rotating freely channel steel around marking time
Horizontality is adjusted and keeps, to ensure that pedestrian steps on the comfort and safety of time of taking the opportunity.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-3, one kind can adjust automatically mark time horizontal wharf ladder, including pedal 3 of going on board, pedal 3 of going on board is fixed
Above deck, 3 lower right of pedal of going on board is provided with ascending stair pedal 1, parallel by four between ascending stair pedal 1 and pedal 3 of going on board
Channel steel 2 connect, the inside parallel of four channel steels 2 be provided with it is multiple mark time 4, handrail 5 is installed, so that pedestrian exists on channel steel 2
The embarkation ladder period of the day from 11 p.m. to 1 a.m is safer, 4 upper surfaces of marking time there are multiple protrusions, increase mark time 4 frictional force, mark time 4 front/rear end
Be respectively fixed with two unthreaded hole lantern rings 6, be mounted on shaft 9 in unthreaded hole lantern ring 6, shaft 9 sequentially pass through from front to back channel steel 2,
Unthreaded hole lantern ring 6, shaft 9 are gap-matched with channel steel 2, and shaft 9 and unthreaded hole lantern ring 6 enable channel steel 2 using being interference fitted
Around 4 rotations of marking time, 9 both ends of shaft are provided with screw thread, and screw thread is located at 2 outside of channel steel, conveniently mark time 4 fixation and disassembly, go on board
Pedal 3 is fixed above deck, is connected, is gone on board between pedal 3 and channel steel 2 by first axle 7 between ascending stair pedal 1 and channel steel 2
It is connected by second hinge 8, first axle 7 and second hinge 8 are in horizontality, so that channel steel 2 is stepped in rotary course
Step 4 is in horizontality always, guarantees that pedestrian steps on the comfort for time of taking the opportunity, and the bottom of ascending stair pedal 1 is provided with idler wheel 10, convenient
Ascending stair pedal 1 adjusts the height of ladder in ground moving, guarantees the safety of ladder.
The working principle of the invention is: when ship pulls in shore, ladder being put down, channel steel 2 is under the effect of gravity around second
Hinge 8 rotate, when idler wheel 10 when being contacted with ground, channel steel 2 stops rotating, ladder formed it is self-locking so that pedestrian steps down in ladder
When, ladder will not integrally generate shaking, ensure that pedestrian steps on the safety taken the opportunity；In the mistake that channel steel 2 is rotated around second hinge 8
Cheng Zhong, since two first axles 7 on ascending stair pedal 1 are in same horizontal line, ascending stair pedal 1 remains horizontal
State, channel steel 2 is rotated around first axle, since channel steel 2 can be around 4 rotations of marking time, according to the property of parallelogram mechanism
Matter, when ladder is formed it is self-locking when, marking time 4 is able to maintain horizontality, ensure that pedestrian steps on the comfort for time of taking the opportunity；Work as ship weight
When changing, the difference in height on deck and ground changes, and idler wheel 10, which will generate, to be rolled to adjust the height of ladder, so that
Ladder reaches new self-locking state, since in this process, deck and ascending stair pedal 1 are in horizontality always, therefore step on
Step 4 will also keep horizontality, so that ladder can adapt to different differences in height.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
