Embodiment 1

[0064] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 As shown, the cold cast anchor of a kind of parallel steel wire intelligent cable provided by the present invention comprises: a plurality of parallel steel wires 1; The intelligent steel wire 2 that is positioned at one side of the parallel steel wires and is internally coupled with an optical fiber grating 32; An anchor cup 3 is equipped with Several fixed sleeves 4 and taper sleeves 5; the fixed sleeve is provided with a fixed hole 6, and the fixed hole is interference fit with one end of the parallel steel wire; the taper sleeve is provided with a mounting hole 7, and the mounting hole is connected to the smart Wire interference fit.

[0065] The interference between the tapered sleeve and the smart steel wire is smaller than the distance between the upper surface of the fiber grating and the surface of the smart steel wire, so as to ensure that the tapered sleeve will not touch the fiber g...

Embodiment 2

[0078] like Figure 7 , Figure 8 As shown, a cold cast anchor of a parallel steel wire smart cable provided by the present invention comprises: a plurality of parallel steel wires; an intelligent steel wire positioned on one side of the parallel steel wires and coupled with an optical fiber grating inside; an anchor cup with several fixing sleeves inside and a tapered sleeve; the fixed sleeve is provided with a fixing hole, and the fixed hole is an interference fit with one end of the parallel steel wire; the tapered sleeve is provided with a mounting hole, and the mounting hole is an interference fit with the smart steel wire.

[0079] The interference between the tapered sleeve and the smart steel wire is smaller than the distance between the upper surface of the fiber grating and the surface of the smart steel wire, so as to ensure that the tapered sleeve will not touch the fiber grating during installation, which will cause the fiber grating to break.

Embodiment 3

[0089] The invention also discloses a method for manufacturing a cold-cast anchor of a parallel steel wire smart cable, which includes the following steps:

[0090] 1) Expand the diameter of the groove at the end of the smart steel wire coupled with the fiber grating in the parallel steel wire smart cable, and put the fiber grating in this section and the free section into a high-temperature resistant protective sleeve, and then place the fiber grating containing the protective sleeve Paste in the steel wire groove to keep the optical fiber at the same height;

[0091] 2) After the parallel steel wires are inserted into the anchor cup, the small-diameter end of the fixing sleeve is inserted into the wire cable body. After installation, the large-diameter end is flush with the ends of the parallel steel wires, and the parallel steel wire bundles are anchored by the fixed sleeve inserted into the ends of the parallel steel wires. The diameter of the enlarged steel wire bundle is...

Abstract

The invention provides a cold-cast anchor of an intelligent cable with parallel steel wires, comprising a plurality of parallel steel wires; intelligent steel wires are located on one sides of the parallel steel wires and coupled with optical fiber gratings inside the intelligent steel wires; An anchor cup is internally equipped with multiple fixing sleeves and conical sleeves; fixing holes arranged in the fixing sleeves, and the fixing holes are interference-fitted with one ends of the parallel steel wires; The fixing sleeves are provided with a mounting holes, and the mounting holes are interference-fitted with the intelligent steel wires. The invention solves the defects that the existing cold-cast anchor of the parallel steel wire intelligent cables uses a wire splitter plate to fixthe parallel steel wire, which is laborious, laborious and error-prone, and is characterized in that the cold-cast anchor of the parallel steel wire intelligent cable uses a wire splitter plate to fix the parallel steel wire.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a cold-cast anchor of a parallel steel wire intelligent cable and a manufacturing method thereof. Background technique [0002] The parallel steel wire rope body is made of multiple steel wires bound parallel to each other and covered with a jacket, and the actual force is realized by the internal steel wires. At present, the commonly used monitoring methods are: pressure ring monitoring method, magnetic flux sensor monitoring method, hydraulic sensor monitoring method. However, the force monitoring of the cable system is a work that requires long-term measurement and real-time monitoring, and the durability, survival rate and stability of the monitoring device need to be considered. Most of the existing monitoring devices belong to the additional parts of the anchorage, the cost is high, and the volume increases after installation. With the development of technology, fiber g...
