The invention discloses a hoisting machine with a separable auxiliary hook trolley and a hoisting method. A main hook trolley is connected with the auxiliary hook trolley through a connecting assembly; a winding assembly and a variable support assembly are arranged on the trolley bottom plate, the variable support assembly has a first state and a second state, the electric push rod device has a first extension in the first state, the included angle between the axial direction of the multi-stage pulley rod and the first direction is larger than 110 degrees, and the electric push rod device has a second extension in the second state. The included angle between the axial direction of the multi-stage pulley rod and the first direction is smaller than 45 degrees, and the first extension amount is smaller than the second extension amount; according to the hoisting machine, the manufacturing cost and the assembling difficulty of the whole hoisting machine can be reduced, and the hoisting range of the multi-stage pulley rod extends to be close to components on the main hook trolley by adjusting the angle between the multi-stage pulley rod and the single-stage pulley rod and the direction relative to the trolley bottom plate; and detection and maintenance of the hoisting equipment are greatly facilitated.
本发明公开了一种具有可分离副钩小车的起重机械及吊装方法,主钩小车通过连接组件与副钩小车连接;小车底板上设置有卷绕组件和可变支架组件,可变支架组件具有第一状态和第二状态,在第一状态下电动推杆装置具有第一伸出量,多级滑轮杆的轴向方向与第一方向之间的夹角大于110度,在第二状态下电动推杆装置具有第二伸出量,多级滑轮杆的轴向方向与第一方向之间的夹角小于45度,第一伸出量小于第二伸出量;本发明的起重机械可以减轻整个起重机械的制造成本和装配难度,通过调整多级滑轮杆和单级滑轮杆之间的角度以及相对于小车底板的方位,确保多级滑轮杆的起吊范围延伸至靠近主钩小车上的部件,极大的方便了起重设备的检测与维修。
