Description
Technical Field
The utility model relates to a bridge prestressing force construction equipment especially relates to steel strand wires wears to restraint construction equipment.
Background
The steel strand pulling machine has the highest use frequency when the steel strands are pulled in a pulling mode, the steel strands are pulled in the pulling mode by the steel strand pulling machine one by one, and the steel strands cannot be pulled in a pulling mode smoothly and are stuck and wound when the steel strands are pulled in the pulling mode to the last few steel strands, so that construction progress and construction quality are seriously affected.
Disclosure of Invention
An object of the utility model is to overcome prior art's shortcoming, provide one kind and improve traditional prestressing force and wear to restraint the process, improve prestressing force and wear to restraint efficiency and quality, the device simple manufacture simultaneously can adapt to the stranded conductor of most of steel strands and wear to restraint the device of operation.
The utility model discloses a steel strand wires wear to restraint device, including the ground tackle that is used for fixing the steel strand wires, the ground tackle include the cylinder, be provided with the external screw thread on the cylinder, along being on a parallel with the axis direction of cylinder on the cylinder open and have a plurality of anchor eyes, each steel strand wires in a bundle of steel strand wires passes an anchor eye respectively, be provided with limit structure respectively at the tip of each steel strand wires that sets up with the anchor cup relatively, limit structure size be greater than the anchor eye;
the anchor cup comprises a circular main body, an internal thread is formed in the inner wall of the circular main body, the circular main body and the anchor cup are in threaded connection with each other, the diameter large end of a truncated cone-shaped main body is consistent with the diameter of the circular main body, the end face of the circular main body is coaxially and fixedly connected with the end face of the diameter large end of the truncated cone-shaped main body, and a traction steel wire rope penetrates through the diameter small end of the truncated cone-shaped main body and is fixedly connected with the truncated cone-shaped main body.
The utility model has the advantages that: the device can improve the traditional prestress strand pulling process, improve the prestress strand pulling efficiency and quality, is simple to manufacture, and can adapt to most of steel strand pulling operations.
Drawings
Fig. 1 is a schematic perspective view of a steel strand pulling device according to the present invention;
FIG. 2 is a schematic view of the anchor of the device of FIG. 1;
figure 3 is a schematic view of the anchor cup of the device of figure 1.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific examples.
As shown in the accompanying drawings the utility model discloses a steel strand pulling device, including the ground tackle 2 that is used for fixed steel strand wires, ground tackle 2 include the cylinder on be provided with the external screw thread, be on a parallel with the axis direction of cylinder be in the cylinder on open and to have a plurality of anchor eyes, each steel strand wires in a bundle of steel strand wires 1 passes an anchor eye respectively, is provided with limit structure 3 respectively at the tip of each steel strand wires that sets up relatively with anchor cup 4, 3 sizes of limit structure be greater than the anchor eye, can prevent that steel strand wires 1 from passing through the anchor eye landing.
The anchor cup comprises a circular main body, internal threads are formed in the inner wall of the circular main body, and the circular main body and the anchor cup are in threaded connection with each other. Preferably, the diameter of the outer wall of the column body is d, and the diameter of the opening end of the circular ring-shaped main body is d +6, so that the column body and the anchor cup can be connected firmly, and the anchor cup is prevented from loosening or separating in the threading process. The diameter of the large end of the circular truncated cone-shaped main body is consistent with that of the circular ring-shaped main body, and the end face of the circular ring-shaped main body is coaxially and fixedly connected with the end face of the large end of the circular truncated cone-shaped main body.
A traction steel wire rope 5 penetrates through the small diameter end of the truncated cone-shaped main body and is fixedly connected with the truncated cone-shaped main body, the traction rope 5 penetrates through the corrugated pipe 6 when the rope is threaded, and a traction device is arranged at the other end of the rope.
The working process of the device is as follows:
when the steel wire rope dragging device is used, a construction worker firstly penetrates the steel wire rope 1 through the anchor hole of the anchor device 2, then the steel wire rope limiting structure 3 is installed at the other end of the steel wire rope, the anchor device and the anchor cup are connected through threads, meanwhile, the dragging rope 5 penetrates the corrugated pipe 6, the dragging steel wire rope is dragged at one end of the corrugated pipe in a manual or mechanical mode, when the steel wire rope 5 is dragged, the anchor cup, the anchor device, the steel wire rope and the like are dragged together through the corrugated pipe 6 through the steel wire rope, and the steel wire rope and the like need to advance at a constant speed in the dragging process.
Claims (2)
