As preferred technical scheme, described loaded plate is the bottom panel of one end of the connection steel strand of internal thread transfer tube.
Further, described drawing head comprises the base plate be embedded in outer silk transfer tube connecting end surface, is welded on the central post that center, base plate plate face, axis are vertical with base plate plate face, and is located at the triangular stall board between base plate and central post.The termination of described central post is provided with draw ring.
Further, described base plate, central post and triangular stall board are formed in one structure.
Further, described outer silk transfer tube is all outer silk or partly outer silk, can adjust according to whether steel strand are super how overweight.
Further, the thickness of described loaded plate is 2 ~ 5cm, and internal diameter is 3 ~ 6cm.
Further, the perforate number on described loaded plate and the number of steel strand adapt, and the diameter of the steel strand of opening diameter and Dan Shu adapts.
Compared with prior art, technical advantage of the present utility model is:
1, the utility model draw ring, drawing head and outer silk transfer tube are formed in one structure, and internal thread transfer tube and loaded plate are formed in one structure, and device overall structure is simple, and loose mail is few, and job site is flexible to operation, saves material, assurance device quality
While, maximized minimizing loose mail number, makes device compact overall structure;
2, be connected firmly, outer silk transfer tube and internal thread transfer tube the reliability effectively strengthening connection is set, traction element and steel strand not easily pull, and working security is high, and construction quality is guaranteed;
3, the design of drawing head easily finds center of effort's point than traditional taper traction first watch, the triangular stall board of both sides can provide effective support, on the drawing head that tractive force is concentrated at work uniformly, be specially adapted to the towage of overweight super many steel strand;
4, loaded plate is installed firmly, form can be arranged flexibly according to construction requirement, the bundle numeral system of corresponding steel strand makes the loaded plate perforate of respective number, and the perforate number also can fixing loaded plate, to adapting to strand bundle numbers different in certain limit, reduces equipment cost.
