Abstract
The utility model relates to a prestressed steel stranded wire traction head. The utility model is characterized in that the prestressed steel stranded wire traction head comprises a traction head and a prestressed steel stranded wire fixing plate, wherein the traction head comprises a front end taper cone and a back end hollow cylinder, the inner wall of the hollow cylinder is provided with internal threads, and the axle center of the taper cone is provided with a penetrated traction hole; the prestressed steel stranded wire fixing plate is a circular steel plate provided with positioning holes the number of which is the same as that of prestressed steel stranded wires, and the hole diameter of the positioning holes is matched with the diameter of a steel wire in a single steel stranded wire; and the outer ring of the circular steel plate is provided with threads which are matched with the internal threads of the hollow cylinder of the traction head. The prestressed steel stranded wire traction head has the advantages that because the circular steel plate can be conveniently connected with a pier of a plurality of steel stranded wires, the connection structure between the circular steel plate and the traction head is compact; and the traction head is provided with a pair of positioning bolts for the fixing plate, which can prevent the separation of the steel stranded wire fixing plate and the traction head in the traction process.
Description
Technical field
The utility model relates to a kind of specific purpose tool that connects high strength low relaxed prestress steel strand in steel pipe, especially a kind of drawing head that connects high strength low relaxed prestress steel strand.
Background technology
At present, connect high strength low relaxed prestress steel strand in the steel pipe in tens of meters distances generally by manually directly connecting, especially for many prestress wires of multiply, connect relatively effort, for connecting high strength low relaxed prestress steel strand in hundreds of meters the overlength steel pipe, only rely on and manually connect the general realization that is difficult to.
Summary of the invention
The purpose of this utility model is: at connecting in steel pipe at present, especially in the steel pipe of long distance, connect the practical problem that high strength low relaxed prestress steel strand manually can't be realized, a kind of special-purpose prestress wire drawing head that relies on the hoist engine traction is provided.
The purpose of this utility model is achieved in that a kind of prestress wire drawing head, it is characterized in that: drawing head and prestress steel twist thread fixing plate, wherein, drawing head contains front end circular cone and rear end hollow cylinder, the inwall of hollow cylinder is to be provided with internal thread, the axle center of circular cone is provided with the towing pad of perforation, the prestress steel twist thread fixing plate is circular steel plate, circular steel plate is provided with the locating hole with the identical number of share of stock of prestress wire, a gauge of wire coupling in the aperture of locating hole and the single steel strand, the outer ring of circular steel plate is provided with screw thread, the internal thread coupling in the hollow cylinder of described screw thread and drawing head.
In the utility model: the thickness of prestress steel twist thread fixing plate is 35mm.
In the utility model: be provided with a pair of fixed head bolt on the drawing head, described a pair of fixed head bolt is oppositely arranged on the hollow cylinder afterbody.
Advantage of the present utility model is: because circular steel plate is provided with the locating hole with the identical number of share of stock of prestress wire, a gauge of wire in the aperture of locating hole and the single steel strand mates, and can easily multiply steel strand wires and circular steel plate pier be connect; Because the external screw thread of circular steel plate and the internal thread of drawing head rear end hollow cylinder coupling can make the multiply steel strand wires that connect with circular steel plate pier fixedly connected with drawing head; Because the front end circular cone of drawing head is provided with towing pad, hauling rope can pass towing pad and be drawn by hoist engine; Drawing head is provided with a pair of fixed head bolt, can prevent that the steel strand wires fixed head separates with drawing head in distraction procedure.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1, drawing head, 2, the prestress steel twist thread fixing plate, 3, locating hole, 4, towing pad, 5, the fixed head bolt.
The specific embodiment
Accompanying drawing discloses the concrete structure of the utility model embodiment without limitation, below in conjunction with accompanying drawing the utility model is done to describe further.
By Fig. 1 Fig. 2 as seen, drawing head 1 contains front end circular cone and rear end hollow cylinder, and the axle center of circular cone is provided with the towing pad 4 of perforation, and the inwall of hollow cylinder is to be provided with internal thread; Prestress steel twist thread fixing plate 2 is circular steel plate, circular steel plate is provided with the locating hole 3 with the identical number of share of stock of prestress wire, a gauge of wire coupling in the aperture of locating hole 3 and the single steel strand, the outer ring of circular steel plate is provided with screw thread, the internal thread coupling in the hollow cylinder of described screw thread and drawing head 1.In the present embodiment, the thickness of prestress steel twist thread fixing plate 2 is 35mm, also is provided with a pair of fixed head bolt 5 simultaneously on drawing head 1, and described a pair of fixed head bolt 5 is oppositely arranged on the hollow cylinder afterbody.
During use, one in each strand of steel strand wires steel wire that is in the center is penetrated locating hole 3 piers corresponding on the prestress steel twist thread fixing plate 2 to be connect, the front end of hauling rope end by drawing head 1 penetrated towing pad 4 and use positioning anchor anchor clamps clamping location (because the volume of positioning anchor anchor clamps is greater than towing pad 4, the hauling rope end can't be withdrawed from), prestress steel twist thread fixing plate 2 after then pier being connect is connected with internal thread with the screw thread of the hollow cylinder of drawing head 1 rear end by coupling, in order to prevent that prestress steel twist thread fixing plate 2 separates with drawing head 1 in distraction procedure, screw thread and internal thread spin put in place after, plate bolt 5 again is tightened.Finish by hoist engine drive straw line end more at last and in steel pipe, connect high strength low relaxed prestress steel strand.
