The invention relates to a triplet type automatic hanging device which comprises a mounting bracket, an electric push rod, a hanger base, a pull rod and a connecting rod mechanism, the top end of the electric push rod is fixed on the hanger base through the mounting bracket, and the bottom end of the electric push rod is connected with the pull rod; the lower end of the pull rod is movably arranged in the lifting appliance base, the pull rod can be driven by the electric push rod to do linear reciprocating motion, and the three sets of connecting rod mechanisms are arranged in the circumferential direction of the lifting appliance base. By the adoption of the triplet type automatic hanging device, when a helicopter hoists a hanging bucket to extinguish fire, the hanging bucket can be rapidly hoisted and flies to an area where fire needs to be extinguished to execute a fire extinguishing task; meanwhile, the hoisting bucket can be quickly replaced, the time for injecting water into the hoisting bucket is saved, the fire extinguishing efficiency is greatly improved, the effective fire extinguishing frequency is increased, the fire extinguishing time is shortened, the fire loss is reduced, and great social value is achieved.

本发明涉及一种三联式自动吊挂装置，包括：安装支架、电推杆、吊具底座、拉杆、连杆机构，电推杆的顶端通过安装支架固定于吊具底座上，电推杆的底端连接有拉杆，拉杆的下端活动设置于吊具底座内、且拉杆能够在电推杆的驱动下做直线往复运动，所述连杆机构设为三组、且沿着吊具底座圆周方向设置。采用本发明三联式自动吊挂装置，直升机吊装吊桶灭火时，能够快速将吊桶吊起飞往需要灭火的区域执行灭火任务；同时能够快速更换吊桶，省去了为吊桶注水的时间，极大地提高了灭火效率，增加了有效灭火次数，缩短了灭火时间，减少了火灾损失，具有极大的社会价值。
