The utility model improves to be had, and described retractable driving device comprises drive motor, gear case, chain wheel set and chain.
The utility model improves to be had, and described telescopic drive motor is servomotor.
The utility model improves to be had, and described telescopic drive motor is installed in first paragraph gangway ladder upper end.
The utility model improves to be had, described first paragraph gangway ladder lower end is provided with the sliding cutting ferrule that rolls, the upper end of described second segment gangway ladder is provided with the sliding cutting ferrule that rolls, the first paragraph gangway ladder is stuck in the cunning of second segment gangway ladder and rolls in the cutting ferrule, while second segment gangway ladder also is stuck in the cunning of first paragraph gangway ladder and rolls in the cutting ferrule, with sliding rolling the second segment gangway ladder is slided by the gangway ladder body at the first paragraph gangway ladder.
The utility model improves to be had, the telescopic drive motor drives drive sprocket by gear case, drive sprocket then drives chain movement, one end of chain is fixed in second segment gangway ladder cunning and rolls the cutting ferrule upper end, one end is by driven sprocket and be fixed in second segment gangway ladder cunning and roll the cutting ferrule lower end, thereby can control the second segment gangway ladder along first paragraph gangway ladder up-and-down movement according to the difference that turns to of motor.
The utility model improves to be had, and described gear case is furnished with the electronic limit device with the flexible length of restriction gangway ladder.
The beneficial effects of the utility model are: the telescopic combination gangway ladder of new structure, work in coordination down by actuating device, first paragraph gangway ladder, second segment gangway ladder, it is flexible to designated length in the situation of any flip angle to control gangway ladder, so that gangway ladder and rope ladder can be used in combination on the water surface elevation arbitrarily.
