The invention provides a lifting hook retracting device and a lorry-mounted crane. The lifting hook retracting device comprises an arm head assembly, a hook retracting support and a lifting hook assembly. The arm head assembly is provided with a first pulley block; the first end of the hook retracting bracket is pivotally connected with one end of the arm head assembly; the lifting hook assembly is connected with the second end of the hook collecting support and comprises a lifting hook and a second pulley block, one end of the steel wire rope is fixed to the arm head assembly, and the other end of the steel wire rope sequentially bypasses the periphery of the second pulley block and the periphery of the first pulley block and is connected with the rope collecting winch. And the hook retracting bracket and the lifting hook assembly can be driven to swing and switch between a horizontal state and a vertical state relative to the arm head assembly. According to the lifting hook retracting device, when the lorry-mounted crane stops or needs to be transported, the lifting hook can be retracted to the horizontal position in front of the arm head assembly, the cargo carrying space of a compartment is increased, and the lifting hook retracting device has the advantages of being small in occupied space of hook retracting, simple in structure, low in manufacturing cost and the like.

    本发明提供一种吊钩收钩装置及随车起重机,该吊钩收钩装置包括臂头组件、收钩支架和吊钩组件;臂头组件设有第一滑轮组;收钩支架的第一端与臂头组件的一端枢转连接;吊钩组件与收钩支架的第二端连接并包括吊钩和第二滑轮组,钢丝绳的一端固定于臂头组件上,另一端依次绕过第二滑轮组和第一滑轮组的外周并连接收绳绞车,收绳绞车控制钢丝绳收紧或释放时,能够带动收钩支架和吊钩组件相对臂头组件在水平状态和竖直状态之间摆动切换。本发明的吊钩收钩装置可以实现在随车起重机停止或需要进行运输时,吊钩能够收起到臂头组件前面的水平位置,增加车厢载货空间,具有收钩占用空间小,结构简洁,制造成本低等特点。
