The lifting appliance upper frame is suitable for being in power connection with a crane carriage, and comprises a first frame body, a second frame body and a third frame body, and at least part of the first frame body extends downwards to form an extension part; the second frame body is arranged on the extension part and is suitable for being in movable contact with the extension part, the second frame body is of a quadrilateral frame structure, and two adjacent frames of the second frame body are hinged through a movable hinge point; the driving device is arranged between the first frame body and the second frame body, and the driving device is suitable for driving the second frame body to rotate relative to the first frame body; and the lifting appliance main body is connected with the second frame body, and the lifting appliance main body is suitable for synchronously moving along with the second frame body. Through mutual cooperation of the two layers of frame bodies and the driving effect of the driving device, the rotation action of a hoisted container on a hoisting plane is achieved only on the upper frame layer of the hoisting tool, a hoisting trolley or even the whole container quay crane does not need to be operated to move, and container alignment operation is facilitated.
本发明涉及一种吊具上架及起重设备,适于与起重小车动力连接,包括:第一架体,至少部分向下延伸设置形成延伸部;第二架体,设置在所述延伸部上并适于与所述延伸部活动接触,所述第二架体呈四边形框架结构,且所述第二架体相邻的两个边框通过活动铰点铰接连接;驱动装置,设置在所述第一架体和所述第二架体之间,所述驱动装置适于驱动所述第二架体相对所述第一架体转动;吊具主体,与所述第二架体相连,所述吊具主体适于随所述第二架体同步运动。通过设置两层架体的相互配合,并通过驱动装置的驱动作用,仅在吊具上架层面便实现了对吊装集装箱在吊装平面上的转动动作,无需操纵起重小车甚至集装箱岸桥整机运动,便于进行对箱操作。
