Equipment for implanting grating optical fiber sensor into steel strand cable body

Abstract

The invention relates to equipment for implanting a steel strand cable body into a grating optical fiber sensor, the equipment comprises a winding mechanism and a drill clamping mechanism, the lower end of the winding mechanism is mounted on the existing working ground, and the drill clamping mechanism is arranged in the middle of the front end of the winding mechanism; a grating optical fiber sensor is implanted into a steel strand cable body by adopting a design concept of a multi-regulation structure, and a pay-off structure and a winding structure of the steel strand cable body in the winding mechanism both adopt convenient structures which can be quickly disassembled and assembled; on the basis that the clamping and drilling mechanism clamps and fixes the steel strand cable body, a structure which plays an auxiliary limiting role on the steel strand cable body is additionally arranged, and the clamping and drilling mechanism can be used for forming double hole grooves at the same time, so that the overall grooving efficiency of the steel strand cable body is improved; the distance between a baffle and an upper clamping block can be in a controllable state through cooperation of a clamping column, a screw ring and a protruding block, then the drilling depth of an electric control drill bit is controlled through cooperation of the baffle and a check block, and then the diversity of the overall forming function of the device can be improved.

Description

technical field [0001] The invention relates to the technical field of steel strand wire-embedded sensors, in particular to a steel-strand wire-embedded grating optical fiber sensor device. Background technique [0002] The steel strand is made of cold drawn round steel wire and notch steel wire for prestressed concrete structure. It is a steel product composed of multiple steel wire strands. Aluminum cladding, copper plating, epoxy resin coating, etc. Steel strands are divided into three types: standard steel strands, engraved steel strands and die-drawn steel strands. The manufacturing process is divided into monofilament manufacturing and strand manufacturing. , High-strength and low-slack prestressed steel strands are mainly used in prestressed reinforced concrete in bridges. It can also be used for geotechnical anchoring, which is commonly used in the protection and reinforcement of highway slopes, and epoxy-coated seven-wire prestressed steel strands and galvanized st...

AI Technical Summary

Problems solved by technology

[0004] 1. When the steel strand body is transported into the drilling structure, it is prone to torsion and is easy to maintain a non-horizontal state, so that the drilling accuracy and the verticality of the hole are deviated. At the same time, the steel strand body under the single structure clamping It is easy to deviate during the drilling process, so that the drilling deviation occurs;

[0005] 2. The common drilling structure is in a state of difficult control as a whole, so that the depth of the drilled grooves, the distance between the grooves and the actual forming requirements are not compatible with each other. overall low efficiency
