Abstract
The utility model relates to a clamp for tensioning a steel strand. The clamp for tensioning the steel strand comprises a cylindrical shell, a cone body and an end cover, wherein the cone body and the end cover are arranged at the two ends of the cylindrical shell. An inner cavity of the cone body is tapered and a pull ring is arranged outside the end cover. A tapered anchor sheet penetrating into the cone body is arranged in the cylindrical shell. The tapered anchor sheet is matched with the inner cavity of the cone body. A spring is arranged between the tapered anchor sheet and the end cover and a top cover which is matched with the cone body in a sliding mode is arranged at the outer end of the cone body in an inserted mode. The clamp for tensioning the steel strand is simple in structure and inserts the head portion of the steel strand from the left end of the top cover to the bottom through the tapered anchor sheet. Afterwards, the cylindrical shell and threads of the end cover are screwed tightly and finally, the clamp is hung to a tensioning device through a hanging ring. In the time of tensioning, the tapered anchor sheet locks the head portion of the steel strand, the mechanical device is used for replacing manpower to reel and unreel the steel strand, and the requirement for ceaseless revolving of the steel strand can be met; after tensioning, the top cover is lightly pressed so as to pull the top cover out. A great deal of labor can be saved in the whole process, the reeling and unreeling efficiency is high, the head of the steel strand can be effectively controlled and potential safety risks are greatly reduced.
Description
Technical field
The utility model belongs to the tension tool technical field of steel strand and steel bar rounding, particularly a kind of steel strand tension jig.
Background technology
Steel strand for prestressed concrete are widely used in the fields such as suspension cable bridge and main equipment lifting, and steel strand are all whole dish packings when dispatching from the factory, and when unwrapping wire is used, there are the following problems: one, because steel strand elasticity is larger, during tap, very easily hurt sb.'s feelings; When two, steel strand extraction is too fast, its internal stress can cause the fast outside bullet of steel strand to put, and injures steel strand unwrapping wire personnel; When three, steel strand unwrapping wire length is longer, need more unwrapping wire personnel, human input is larger.Therefore, how realizing high efficiency extraction steel strand, significantly reduce potential safety hazard, is a difficulties urgently to be resolved hurrily.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, unwrapping wire efficiency is high, can effectively control steel strand head and greatly subdue the steel strand tension jig of potential safety hazard.
For achieving the above object, the technical solution of the utility model is: a kind of steel strand tension jig, comprise cone and end cap that cylindrical case body and cylindrical case body two ends arrange, and cone cavity is tapered, and end cap outside is provided with draw ring; In described cylindrical case body, be provided with the anchoring cone sheet that stretches into cone inside, anchoring cone sheet and cone cavity adapt, and between anchoring cone sheet and end cap, are provided with spring; Outer end of the cone is fitted with the top cover being slidably matched.
Described cylindrical case body is threaded with cone, end cap.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises cone and the end cap that cylindrical case body and cylindrical case body two ends arrange, and cone cavity is tapered, and end cap outside is provided with draw ring; In described cylindrical case body, be provided with the anchoring cone sheet that stretches into cone inside, anchoring cone sheet and cone cavity adapt, and between anchoring cone sheet and end cap, are provided with spring; Outer end of the cone is fitted with the top cover being slidably matched, it is simple in structure, before use, cylindrical case body and end cap are in unassembled state, steel strand head is inserted from the left end of top cover, and make it pass through anchoring cone sheet until then tighten the screw thread of cylindrical case body and end cap bottom, finally jig is hung over to stretch-draw mechanically by draw ring; During stretch-draw, anchoring cone sheet is locked by steel strand head, with plant equipment, replaces artificial extraction steel strand, and in unwrapping wire process, jig and stretch-draw machinery couple together, and can meet the requirement that steel strand do not stop rotation; After stretch-draw, the lid that gently bears down on one can be extracted jig out; Whole process can be saved a large amount of labours, and unwrapping wire efficiency is high, can effectively control steel strand head, thereby greatly subdues potential safety hazard.
2, cylindrical case body is threaded with cone, end cap, is convenient to dismounting, replacing, uses flexible and convenient; By changing anchoring cone sheet, to adapt to the requirement of different size steel strand tension.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model.
The specific embodiment
Steel strand tension jig as shown in Figure 1 and Figure 2, it comprises cone 2 and end cap 5 that cylindrical case body 4 and cylindrical case body 4 two ends are threaded, and the inner chamber of cone 2 is tapered, and end cap 5 outsides are provided with draw ring 6.In cylindrical case body 4, be provided with the anchoring cone sheet 3 that stretches into cone 2 inside, anchoring cone sheet 3 adapts with the inner chamber of cone 2, and the boss of anchoring cone sheet 3 is corresponding with the end face of cone 2.Between anchoring cone sheet 3 and end cap 5, be provided with spring 7, for the reset of anchoring cone sheet 3.In cone 2 outer ends, be fitted with the top cover 1 being slidably matched, top cover 1 is inner corresponding with anchoring cone sheet outer end.
Before the utility model is used, cylindrical case body 4 and end cap 5 are in unassembled state, steel strand head is inserted from the left end of top cover 1, and make it pass through anchoring cone sheet 3 until bottom, then, cylindrical case body 4 and the screw thread of end cap 5 are tightened, last, jig is hung over to stretch-draw mechanically by draw ring 6.During stretch-draw, anchoring cone sheet 3 is locked by steel strand head, with plant equipment, replaces artificial extraction steel strand, and in unwrapping wire process, jig and stretch-draw machinery couple together, and can meet the requirement that steel strand do not stop rotation; After stretch-draw, gently bear down on one and cover 1 and jig can be extracted out.
The utility model is also applicable to the stretch-draw of steel bar rounding.
Claims (2)
