Detailed Description
The following detailed description of the technical solutions according to the embodiments of the present utility model will be given with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 to 4, the auxiliary hanging structure 100 of the tower crane comprises an auxiliary hoist 101 and a rotating base 102, wherein a first fixed pulley 103 is installed on the rotating base 102, an auxiliary hanging arm 104 is installed on the first fixed pulley 103, the auxiliary hanging arm 104 is rotatably installed on the rotating base 102, a second fixed pulley 105 and a third fixed pulley 106 are respectively installed at two ends of the auxiliary hanging arm 104, an adjusting pulley 107 is further installed between the second fixed pulley 105 and the third fixed pulley 106, a plurality of adjusting holes 108 for installing the adjusting pulley 107 are formed in the auxiliary hanging arm 104, a steel wire rope 109 led out by the auxiliary hoist 101 sequentially passes through the first fixed pulley 103, the second fixed pulley 105, the adjusting pulley 107 and the third fixed pulley 106, and the steel wire rope 109 between the first fixed pulley 103 and the second fixed pulley 105 maintains a vertical state.
In the embodiment, an auxiliary hoisting structure is arranged on the tower crane, and a motor, a speed reducer or a slewing mechanism which needs to be replaced in hoisting can be realized through the cooperation of a winch and a pulley; the auxiliary suspension arm can rotate, and can rotate to a required position according to the requirement, and the steel wire rope between the first fixed pulley and the second fixed pulley is kept in a vertical state, so that the rotation of the suspension arm can not cause the falling-off of the steel wire rope; in addition, an adjusting pulley is arranged between the second fixed pulley and the third fixed pulley, when a heavy object is lifted, the heavy object can be directly lifted from the adjusting pulley without the third fixed pulley, two positions of the adjusting pulley can be selected, two kinds of working amplitude can be selected, and three kinds of working amplitude can be realized by lifting the heavy object through the third fixed pulley.
