Embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.Following examples are only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality can not be limited with this
New protection domain.
As depicted in figs. 1 and 2, the crawler crane that a kind of intelligent adaptive of swing arm 3 limit is raised, it is characterised in that：Including
The hoist engine that crawler body 1, swing arm 3, revolving dial 2, controller and driving swing arm 3 rise or declined, hoist engine and swing arm 3 are pacified
Loaded on revolving dial 2, revolving dial 2 is installed on crawler body 1；The root of swing arm 3, which is provided with, to be obtained swing arm 3 and rises angle
Angular transducer, controller obtain angular transducer feedback swing arm 3 rise angle arrive at limit value angle signal control
Hoist engine stops driving swing arm 3 and risen.
In the present embodiment, hoist engine includes motor 8, decelerator 7, reel 6 and lift rope 4, and lift rope 4 is wound in and reel
On 6, its one end is fixed on reel 6, and the other end is fixed on the lifting end of swing arm 3, and motor 8 connects reel 6 by decelerator 7 and driven
The positive and negative rotation of movable reel 6, so as to wind or release lift rope 4 to rise or decline swing arm 3, it is anti-that controller obtains angular transducer
The angle signal controlled motor 8 that the angle that the swing arm 3 of feedback rises arrives at limit value shuts down, and angular transducer passes through data transfer
