Tool connection, other end connection traction apparatuss.
Further, the directive wheel keeper is the anchor ear of one end open, and the non-opening on the anchor ear is provided with company
Connect platform；The guide wheel assemblies are linked as entirety by the connecting platform with the directive wheel keeper；The anchor ear opening
One end arrange locking member.
Further, the locking member is a pair of engaging lugs being placed at the anchor ear opening, is opened up on the engaging lug
It is some to assemble conjunction screw, installation locking bolt in screw.
Further, the guide wheel assemblies include guide wheel bracket and directive wheel, and the directive wheel is fixed by rotating shaft
On the guide wheel bracket, and the duct that indwelling is passed through for pull rope between the directive wheel and guide wheel bracket.
Further, enter hole for ease of steel for wire drawing, prevent occurring position offset problem in distraction procedure, the drag-line
Suspender is fixed on drag-line apart from the position of 1 ~ 3m of steel for wire drawing.
Further, the traction apparatuss are hoist engine.
Further, the guide wheel assemblies are apart from the m of the hoist engine 15 ~ 30.
Beneficial effect：This utility model provide apparatus structure it is simple, stability is high, easy making, easy accessibility and into
This is cheap, work efficiency is greatly improved when constructing using this device and saves artificial and machinery, and suspension cable anchor head more easy to control enters
Suo Kong, whole distraction procedure is not directly to anchor head force, it is to avoid the damage to anchor head silk mouth；（2）This device can be according to rope hole
The angle of size and suspension cable enters the adjustment of row distance and size, improves construction accuracy.
