So-called binodal telescopic gangway ladder device is exactly the drinking water state according to boats and ships, makes the bed ladder of accommodation ladder system successfully be slided into and be skidded off by fly, to reach the object of safe handling by affecting of accommodation ladder winch. The advantage of at present domestic and international binodal telescopic gangway ladder: 1. simple in structure, easy for installation, flexible, gangway ladder can regulate arbitrarily according to the variation of drauht the length of gangway ladder; 2. solved because single-unit ladder is oversize, be difficult to meet the problem of requirement of strength. But also there is following shortcoming: 1. current binodal telescopic gangway ladder is flexible, relies on the artificial folding and unfolding of a winch completely, realizes the flexible of lower joint gangway ladder, once the phenomenon that telescopic section is stuck easily appears in the discontinuity equalization of gangway ladder simultaneously; Need to go manually to intervene. 2. general binodal telescopic gangway ladder can not be followed the variation of the draft of boats and ships, and automatic telescopic needs artificial releasing winch hawser, reaches the flexible of gangway ladder, cannot independently stretch. 3. current binodal telescopic gangway ladder is in telescopic process, and lower platform is followed gangway ladder in motion simultaneously, if boats and ships heave amplitude is larger, the scope that the lower platform of gangway ladder moves is just larger, can not adapt to apply on smaller transition platform. When occurring because of wave that boats and ships are upper and lower, move left and right while there is lower platform vacant state, general binodal telescopic gangway ladder just can not and alarm, the personnel that cause walk to occur danger gangway ladder is up.
Summary of the invention
For solving deficiency of the prior art, the purpose of this utility model is to provide one to be useful on boats and ships, ocean platform, when shipping draft or while there is tidal condition, gangway ladder Full-automatic telescopic, ensures that personnel can be smoothly by the upper and lower automatic telescopic gangway ladder of gangway ladder safety at any time.
For reaching above object, the technical scheme that the utility model is taked is:

Further, described retractable driving device comprises the tooth bar that is installed on the servomotor of mounting gangway, horizontal angular wheel shaft, two vertical axes and is installed on the both sides of mounting gangway, described horizontal angular wheel shaft is installed on bottom and the two ends of mounting gangway and stretches out, two external parts of horizontal angular wheel shaft are separately installed with bevel gear, described two vertical axes are installed on the both sides of mounting gangway through support respectively, the bottom of vertical axes is provided with the bevel gear engaging with bevel gear, and the top of vertical axes is provided with the driven wheel engaging with tooth bar.
Further, the reducing gear between described servomotor and horizontal angular wheel shaft more than one-level is connected, and friction clutch and emergent clutch are installed on angular wheel shaft.
Again further, in the reel rotating shaft of described hoisting gear, be connected with manual setter.
Take after above technical scheme, the beneficial effects of the utility model are:
Automatic telescopic gangway ladder comprises gangway ladder frame for movement, accommodation ladder winch, four parts of signal collecting and controlling system. Gangway ladder frame for movement comprises binodal telescopic gangway ladder, mounts gangway and lower gangway ladder for main point; Mount gangway and formed by rack-and-pinion, servo-drive, pulley guide rails, hoist cable with lower gangway ladder. Upper mounting plate is connected with boats and ships, and gangway ladder is connected by rotating shaft with upper mounting plate, and gangway ladder can be freely movable within the scope of 10 ° of left and right directions, and upper angle of declination maximum can reach 55 °. Accommodation ladder winch is the major impetus of traction gangway ladder folding and unfolding, adopts the driving of variable-frequency motor as winch, can accurately control like this distance of folding and unfolding, can accomplish at short notice again folding and unfolding frequently simultaneously.
Signals collecting mainly adopts tension pick-up,, is moved by control system commander's accommodation ladder winch and active telescoping mechanism to control system by tension pick-up signal transmission. Warning when angular transducer was mainly to provide wide-angle.
Control section mainly contains PLC, servo-driven module, signal processing module and relay, braking controlling composition; It is the command centre of whole system.
The utility model controls retractable driving device after utilizing sensor collection angle and pulling force data and using PLC controller collection receipt and hoisting gear completes flexible and folding and unfolding action, thereby realize according to the variation of drauht, automatically regulate arbitrarily the length of gangway ladder, gangway ladder is in best use state all the time, and the personnel of guarantee step on comfortable safety while taking advantage of gangway ladder; Gangway ladder retractor device is telescopic system initiatively, has adopted rack-and-pinion to add servo drive, guaranteed capable of expansion and contraction, reliable, without manual operation.
