Above-mentioned amplitude variation type dock boarding ladder, described power source mechanism comprises handwheel and the reduction box that is driven by handwheel, the output of reduction box is connected with capstan winch by driving chain.
Furthermore, described luffing ladder is provided with transition disc, is located at some foot rests, synchronous plate and synchronous junction plate on the luffing ladder, transition disc and the coaxial setting of capstan winch, transition disc is connected with synchronous plate by the transition chain, and synchronously junction plate was not only hinged but also hinged with foot rest with synchronous plate.
Simultaneously, above-mentioned amplitude variation type dock boarding ladder, described some foot rests wherein have the insurance pin-and-hole that matches with the luffing ladder on a foot rest.
During this time, amplitude variation type dock boarding ladder described in the utility model, described luffing ladder are provided with and are used to make the luffing ladder to be fixed on hook on the boats and ships.
And described chain-wales is provided with the platform guardrail.
Described luffing ladder is provided with terraced hand saver hurdle.
The ladder equipment that is used to climb up boats and ships in described in the utility model and the prior art in dock is compared, and it has the following advantages:
The utility model will be designed to be articulated and connected between luffing ladder and the chain-wales, and described amplitude variation type dock boarding ladder also comprises the drive unit that is used to drive the hinged rotation on chain-wales of luffing ladder.When boats and ships enter dock, the operator can be according to the height of going on board of boats and ships, by regulating drive unit to realize regulating the height of luffing ladder, so that its appropriate being articulated on the boats and ships, dock need not clever snake various ways, the boarding ladder of plurality of specifications, can effectively reduce the boarding ladder configuration of building berth, and, for the boats and ships height of differing heights, the luffing ladder all is adjustable to suitable amplitude (also being angle), and is easy to operate, during this time, the length of luffing ladder also can be designed to Collapsible structure, to adapt to different height and the positions of going on board to a greater extent, makes more simple and flexible of structure of the present utility model.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Accompanying drawing 2 is the structural representation of the utility model after the luffing ladder is adjusted to certain angle of going on board.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to illustrated in figures 1 and 2, the described amplitude variation type dock of present embodiment boarding ladder, it comprises chain-wales 1 and luffing ladder 2, between described luffing ladder 2 and the chain-wales 1 for being articulated and connected, chain-wales 1 horizontal fixed is installed, luffing ladder 2 can rotate around chain-wales 1, with the height of realization luffing ladder 2 and the purpose of variable-angle.Described amplitude variation type dock boarding ladder also comprises the drive unit that is used to drive luffing ladder 2 hinged rotation on chain-wales 1.Furthermore, described drive unit comprises power source mechanism and is arranged on and be used for the capstan winch 3 hinged with chain-wales 1 on the luffing ladder 2 that power source mechanism is connected with capstan winch 3 by driving chain 4.
During this time, described power source mechanism comprises handwheel 5 and the reduction box 6 that is driven by handwheel 5, and the output of reduction box 6 is connected with capstan winch 3 by driving chain 4.Described luffing ladder 2 is provided with transition disc 7, is located at some foot rests 8, synchronous plate 9 and synchronous junction plate 10 on the luffing ladder 2, transition disc 7 and capstan winch 3 coaxial settings, transition disc 7 is connected with synchronous plate 9 by the transition chain, synchronously junction plate 10 was not only hinged but also hinged with foot rest 8 with synchronous plate 9, it all is levels that foot rest 8 guarantees thus, in addition, the length of luffing ladder 2 also can be designed to Collapsible structure, to adapt to different height and the positions of going on board to a greater extent, make more simple and flexible of structure of the present utility model.Beyond present embodiment, people can change handwheel 5 as motor or starting device, can realize the effect of motor-driven adjusting luffing ladder 2.
