本发明涉及一种自适应卷收和伸展式伤病员海上换乘装置,其特征是：包括展撤机构、桥面机构和担架托架，所述展撤机构的卷筒外表面与桥面机构一端连接；所述桥面机构展开后在两船之间形成平直的桥面通道，撤收后卷在卷筒上；所述桥面机构末端的连杆上设有搭钩；所述担架托架套装在桥面机构上。有益效果：本发明能够在并靠船舶发生相对运动时自适应卷收和伸展，具有一定波浪补偿功能；桥面机构展开后形成平直承载面，供担架托架滑行和人员攀登，卷收后易于存放，占用空间小；适应两船舷差为±3米，满足不同甲板伤病员或人员传送需要；既能由低干舷船舶向高干舷船舶传送伤病员或人员，也能由高干舷向低干舷传送。

The invention relates to a self-adaptive rolling and stretching type sea transfer device for sick and wounded patients. The device is characterized by comprising an unfolding and dismantling mechanism, a bridge deck mechanism and a stretcher bracket, the external surface of a reel of the unfolding and dismantling mechanism is connected with one end of the bridge deck mechanism, and the bridge deck mechanism is unfolded to form a straight bridge passage between two vessels, and the bridge deck mechanism is rolled on the reel after being rolled up; a connecting rod on the tail end of the bridge deck mechanism is provided with an agraffe, and the stretcher bracket is arranged on the bridge deck mechanism in a sleeving mode. The self-adaptive rolling and stretching type sea transfer device for sick and wounded patients has the advantages that the device can self-adaptively roll and stretch when the vessels dock abreast to produce relative motions, and the device has a certain wave compensation function; the bridge deck mechanism is unfolded to form a straight bearing surface for the stretcher bracket to glide and the personnel to climb, the device is easy to store after the roll-up, and the occupied space is small; the device is adapted to a difference of plus or minus 3 meters between two rails of the vessels and meets the needs for transferring the sick or wounded patients on different decks; the sick or wounded patients or personnel can be transferred from lower-rank freeboard vessels to higher-rank freeboard vessels, and from the higher-rank freeboard vessels to the lower-rank freeboard vessels.
