Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
With reference to Fig. 1 and Fig. 2, a kind of wind turbine detaching device for coupling, including clamping jaw 1 and connecting plate are present embodiments provided
2, connecting plate 2 is connected with two groups of clamping jaws 1, and clamping jaw 1 includes connecting rod 16 and the left side pawl 11 for being articulated with 16 both ends of connecting rod
With the right pawl 12, the upper surface of connecting rod 16 is equipped with lantern ring 161, and connecting plate 2 is slidably sheathed on lantern ring 161, left side pawl 11 with
The opposite side of the right pawl 12 is hinged with threaded rod 13, and the side opposite with left side pawl 11 of the right pawl 12 is hinged with screw rod set 14,
The outer sheath of screw rod set 14 is equipped with thread bush 15, and threaded rod 13 is sheathed on 14 inside of screw rod set and is threadedly coupled with thread bush 15.
The utility model structure is simple, can pass through clamping jaw 1 that 2 both ends of connecting plate are arranged symmetrically while remove the bolt at 3 both ends of shaft coupling
4, it is convenient and efficient；In addition, the width of 12 grip axes of left side pawl 11 and the right pawl of clamping jaw 1 can pass through threaded rod 13 and thread bush 15
It is adjusted, the bolt 4 suitable for different-diameter is extracted, and applicability is stronger.
In use process, the support device of separating jack is set between connecting plate 2 and shaft coupling 4, then will
Power device is connected to outside the cabin of blower and is operated, easy to operate, and avoids causing safety problem to staff.
Further, left side pawl 11 and the right pawl 12 are equipped with hook portion 111, left side pawl 11 far from one end of connecting rod 16
