Problems solved by technology

In the above-mentioned method, controlling and adjusting the posture of the hanging objects by means of human traction requires the cooperation of multiple people, which requires additional labor costs and causes a waste of human resources; at the same time, this operation method also has great potential dangers. Falling may cause casualties; in addition, the posture control and adjustment of the hanging object through auxiliary vehicles or devices requires high coordination ability of various operating vehicles and operators, and the cost is relatively high

no. 1 Embodiment

[0056] The attitude adjustment device includes: a drum assembly and a drive assembly; the drum assembly includes a first drum 1 and a second drum 2 arranged coaxially side by side; the first drum 1 is wound with a first wire rope, and the first wire rope has a Free end, the free end of the first wire rope is connected to one end of the hanging object; the second reel 2 is wound with a second wire rope, the second wire rope has a free end, and the free end of the second wire rope is connected to the other end of the hanging object; The rotation directions of the first wire rope and the second wire rope are opposite; the driving component drives the first reel 1 to rotate, or the driving component 2 drives the second reel to rotate, or the same driving component drives the first reel 1 and the second reel 2 synchronously rotate.

[0057] When the crane adjusts the attitude of the hanging object, the first wire rope and the second wire rope of the drum assembly are respectively c...

no. 2 Embodiment

[0118] The attitude adjustment device includes: a reel assembly and a drive assembly; the reel assembly includes a first reel and a second reel set independently; the drive assembly includes a first drive assembly and a second drive assembly set independently; on the first reel A first wire rope is wound, the first wire rope has a free end, and the free end of the first wire rope is connected to one end of the hanging object; the second reel is wound with a second wire rope, the second wire rope has a free end, and the second wire rope has a free end. The free end is connected to the other end of the hanging object; the first driving component independently drives the first reel to rotate, and the second driving component independently drives the second reel to rotate.

[0119]When the crane adjusts the attitude of the hanging object, the first wire rope and the second wire rope of the drum assembly are respectively connected to the two ends of the hanging object, so that the h...

no. 3 Embodiment

[0123] The attitude adjustment device includes: a drum assembly and a drive assembly; the drum assembly is a separate drum, and the drive assembly is a separate drive motor; the wire rope is wound on the drum and has a first free end and a second free end; the wire rope The two free ends of the hoist are respectively connected to the two ends of the hanging object; the driving motor drives the reel to rotate.

[0124] When the crane adjusts the attitude of the hanging object, the two free ends of the wire rope are connected to the two ends of the hanging object respectively, so that the hanging object has a first force connection point and a second force connection point at two positions, and the hanging object is suspended on the main The end of the arm section. When the driving motor drives the reel to rotate, the first free end and the second free end of the wire rope must be retracted and retracted in the opposite direction, thereby realizing the lifting / pulling of the fir...

Abstract

The invention discloses a crane. The crane comprises a crane body; the posture adjusting device can be mounted on the crane body; the posture adjusting device comprises a winding drum assembly wound with a steel wire rope connected with a hanging object; and the driving assembly drives the winding drum assembly to rotate so as to wind / unwind the steel wire rope, and pulls the hoisted object by winding / unwinding the steel wire rope so as to realize posture adjustment of the hoisted object. According to the crane provided by the invention, the posture adjusting device is mounted on the crane body, and the posture adjustment of the hoisted object can be realized through the posture adjusting device, so that the posture adjustment of the hoisted object can be independently finished by one crane; in the operation process, manual traction is not needed, the extra labor cost is reduced, and the safety performance of operation is enhanced; in addition, in the operation process, an auxiliary vehicle or device does not need to be used for controlling and adjusting the posture of the hoisted object, the requirement for the cooperative operation capacity of all operation vehicles and operators does not need to be high, and the operation cost is further reduced.

Description

technical field [0001] The present application relates to the technical field of cranes, and more particularly, to a crane capable of adjusting the attitude of hanging objects by a single mechanical operation. Background technique [0002] The main function of the hoisting machinery is to hoist the items (hoisting objects) required for the operation to a certain height and hoist the items (hoisting objects) to the target position through rotation, luffing and other actions. However, in some special scenarios, there are also high requirements for the attitude of the hanging object at a certain moment, such as the installation of wind turbine components, the stacking of containers, etc. For example, the current installation method of domestic wind turbine components is mainly: after the crane lifts the components, the posture of the hanging object is controlled by manual traction for installation; the common installation method of European wind turbine components is: a large-t...
