Above-mentioned be detachably connected is bolt connection.
In order to realize torsion transmission of the attaching/detaching apparatus to thread-locking ring, and reach convenient fixed purpose, this practicality is new
Type setting fix bar is Z-shape, and axial torsion connecting rod is in τ shapes.
Bar-shaped trough both ends are provided with the convex structure that diameter is more than bar shaped well width, it is possible to achieve radial direction torsion connecting rod is in axle
Rotating freely in bar-shaped trough on to torsion connecting rod, radial direction torsion connecting rod is facilitated to carry out position adjustment.
The utility model has the advantages that compared to prior art：
1st, the utility model middle sprocket and gear belong to planetary gear train, using planetary gear train is compact-sized, small volume, quality
Small, large carrying capacity, power bracket and the big design feature of transmission range are transmitted, realize the function of slowing down and increase and turn round, can be dismounting
Thread-locking ring provides larger moment of torsion, to meet the dismounting work of large-size thread-locking ring.
2nd, disassembly process can work continuously using manpower as driving force, solve crane gear torque and be difficult to control,
Oblique pull askew the problem of dragging be present, can safely and efficiently realize the dismounting operation of thread-locking ring.
3rd, the utility model plant area space is small, avoids the feelings that thread-locking ring can not be dismounted caused by space limits
Condition occurs.
4th, dentition uses open architecture in the utility model device, and assembling is simple, and not high to required precision, all parts are equal
It is cheap for general part common in factory, wide material sources, cost.
