Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as Figure 1~2 As shown, the invention provides a steel wire rope and steel strand traction connection device, comprising:

[0027] A traction connection device for a steel wire rope and a steel strand, including an anchor ring, a four-leaf clip and a U-shaped ring:

[0028] The anchor ring is provided with a tapered through hole for the steel strand to pass through in the axial direction;

[0029] The four-leaf clamp is located in the thick end of the tapered through hole, and is used to clamp the steel strand;

[0030] The ends of the two arms of the U-shaped ring are welded on the anchor ring, and the thick end of the tapered through hole faces the bottom of the U-shaped ring.

[0031] On the basis of the above technical solution, the diameter of the narrow end of the tapered through hole is smaller than the outer diameter of the four-leaf clip.

Abstract

The invention discloses a traction connection device for a steel strand and a steel wire rope and an installation method of the traction connection device. The traction connection device for the steelstrand and the steel wire rope comprises a U-shaped hanging ring, an anchor ring and a four-blade clamping piece, the ends of two arms of the U-shaped hanging ring are welded on the outer wall of theanchor ring, the anchor ring is axially provided with a tapered through hole through which the steel strand passes, a thick end of the tapered through hole is internally provided with the four-bladeclamping piece, the steel strand passes through the tapered through hole and is fixed with the four-blade clamping piece, and the steel wire rope is connected with the U-shaped hanging ring through aU-shaped shackle, that is, the steel wire rope is connected with the steel strand after passing through the traction connection device. The traction connection device is used for connecting the steelwire rope with the single steel strand, installation is convenient and rapid, a single steel strand is pulled by using the steel wire rope of a winch, and the traction installation efficiency of the steel strand is improved.

Description

technical field [0001] The invention relates to the technical field of engineering, in particular to a traction connection device for a steel wire rope and a steel strand and an installation method thereof. Background technique [0002] In the field of engineering construction, the use of prestressed steel strands is very common. When the long strands of steel strands are pulled by cables, in order to improve work efficiency, they are often drawn by hoist wire ropes. The diameters of the wire ropes and steel strands are often not equal, and it is difficult to connect them together with standard clamps. Therefore, there are difficulties in the connection between the steel wire rope and the steel strand. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a traction connection device for a steel wire rope and a steel strand and an installation method thereof. [0004] The technical scheme provided by the present...
