Abstract
The utility model provides a prestress wire drafting tool, including the drawing head with set up at the rear end of drawing head afterbody locating component, wherein, the drawing head is by the circular cone of front end and the hollow cylinder integrated into one piece of rear end, just the circular cone link up with hollow cylinder is inside, the hollow cylinder rear inside wall of drawing head stretches out two stoppers, rear end locating component includes two at least fixing bolt and cylindrical rubber buffers that set up crisscross relatively, the center department of rubber buffer with the drawing head link up. The utility model discloses a rubber buffer and fixing bolt cooperate, and effect through fixing bolt is the surface of steel strand wires with the partial fixing or the embedding rubber buffer of rubber buffer contact, play the constraint effect to steel strand wires through the frictional force between rubber buffer and the steel strand wires, pull effectually, difficultly produce phenomenons such as steel strand wires slide, and simple structure, be convenient for equipment and production.
Description
Technical field
The invention belongs to steel strand special tool field, especially relates to a kind of prestress wire traction instrument.
Background technology
At present, high strength low relaxed prestress steel strand is connected generally by manually directly connecting in steel pipe in tens of meters of distances, connect and compare effort, high strength low relaxed prestress steel strand is connected in the overlength steel pipe of hundreds of meters, only rely on and manually connect general very difficult realization, though the traction type equipment or the instrument that have many steel strand on the market, some traction instrument to there is traction dynamics little, easily there is the problems such as steel strand disengaging in distraction procedure.
Summary of the invention
In view of this, the invention is intended to propose a kind of prestress wire traction instrument, to solve prior art Problems existing.
For achieving the above object, the technical scheme of the invention is achieved in that
A kind of prestress wire traction instrument, comprise drawing head and it is arranged on the rear end positioning component of drawing head afterbody, wherein, drawing head is one-body molded by the hollow cylinder of the circular cone of front end and rear end, and described circular cone and hollow cylinder internal run-through, the hollow cylinder rear inner side-wall of described drawing head stretches out two limited blocks, and described rear end positioning component comprises standing bolt and the cylindrical rubber plug that at least two staggered relative are arranged, and center and the described drawing head of described rubber plug are through.
Further, the external diameter of described rubber plug equals the internal diameter of hollow cylinder described in described drawing head rear portion.
Further, one end and the described limited block card of described rubber plug connect, and the other end is provided with two handles.
Further, described standing bolt is successively through described drawing head sidewall and described rubber plug sidewall.
Relative to prior art, the prestress wire traction instrument described in the invention has following advantage:
The present invention adopts rubber plug to match with standing bolt, by the effect of standing bolt, the part that steel strand contact with rubber plug is fixed or is embedded the surface of rubber plug, the constraint effect to steel strand is played by the frictional force between rubber plug and steel strand, traction effect is good, not easily produce the phenomenons such as steel strand slippage, and structure is simple, it is convenient to assembling and produces.
Accompanying drawing explanation
The accompanying drawing of a part forming the invention be used to provide to the invention it is further understood that the schematic description and description of the invention is for explaining the invention, do not form the improper restriction to the invention. In the accompanying drawings:
Fig. 1 is the structural representation of the traction instrument of the prestress wire described in the invention.
Embodiment
It should be noted that, when not conflicting, the embodiment in the invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and come the invention is described in detail in conjunction with the embodiments.
A kind of prestress wire traction instrument, as shown in Figure 1, comprise drawing head 1 and it is arranged on the rear end positioning component of drawing head afterbody, wherein, drawing head 1 is one-body molded by the hollow cylinder of the circular cone of front end and rear end, and described circular cone and hollow cylinder internal run-through, the hollow cylinder rear inner side-wall of described drawing head stretches out two limited blocks 2, described rear end positioning component comprises standing bolt 3 and the cylindrical rubber plug 4 that at least two staggered relative are arranged, and center and the described drawing head of described rubber plug 4 are through.
Wherein, the external diameter of described rubber plug 4 equals the internal diameter of hollow cylinder described in described drawing head 1 rear portion; One end and the described limited block card of described rubber plug connect, and the other end is provided with two handles 5; Described standing bolt is successively through described drawing head sidewall and described rubber plug sidewall.
The foregoing is only the better embodiment of the invention; not in order to limit the invention; within all spirit in the invention and principle, any amendment of doing, equivalent replacement, improvement etc., all should be included within the protection domain of the invention.
