Vibrating wire sensor installation tool and vibrating wire sensor installation method

Abstract

The present invention provides a vibrating wire sensor installation tool and a vibrating wire sensor installation method. The installation tool comprises a cushion block clamp and two cushion blocks;the two sides of the bottom portions of the cushion blocks are respectively provided with protrusion portions, and the middle portions of the cushion blocks are provided with through holes which can be passed through by a vibrating wire sensor; the cushion block clamp comprises a regulation module and two clamps; the middle portions of the two clamps are respectively provided with clamping portions, the top portions of the two clamps are respectively provided with clips, each clamp portion comprises two clamping pieces clamped at two sides of one cushion block, and the tail end of each clamping piece is provided with one connecting piece; the two clamps are slidingly connected through the connecting pieces; the regulation module comprises a regulator and two fixing plates; the two ends ofthe fixing plates are respectively fixed at the two clamping pieces of the clamps; the two ends of the regulator are respectively fixed on the two fixing plates; and the regulator is provided with a fine tuning knob configured to elongate and shorten the length of the regulator. The vibrating wire sensor installation tool and the vibrating wire sensor installation method can save the installationtime of the vibrating wire sensor, can reduce the work risk, and can improve the regulation speed and the precision of the vibrating wire sensor.

Description

technical field [0001] The present application relates to the technical field of stress and strain testing, in particular to an installation tool and an installation method of a vibrating wire sensor. Background technique [0002] Stress-strain testing is a common method for testing engineering structures or structural components during testing, construction, and monitoring, and is an important means to evaluate the safety of structures or components. The location for stress-strain testing can be the surface and interior of structures or components. In the prior art, the main method of stress-strain testing is to measure by installing sensors. The vibrating wire strain sensor has become a commonly used strain test sensor due to its simple structure, reliable operation and good durability. [0003] The vibrating wire strain sensor consists of three components: an outer cylinder, a vibrating wire, and an electromagnetic coil, and is connected to the surface of the structure ...

Problems solved by technology

[0015] Moreover, since the manual adjustment of the sensor depends entirely on the experience and feel of the workers, not only does it require repeated adjustments during the adjustment process, which is time-consuming, but also the final adjustment accuracy is limited.

[0016] During the actual testing or monitoring of engineering structures, the surface of the structure to be tested is often located at high altitude or other areas that are difficult for testers to reach, so the operation of installing sensors has some risks (for example, high-altitude operations may be required, etc.)

However, at least the above 6 steps are required to completely perform the above-mentioned process of installing and adjusting the sensor, so it is not only time-consuming and labor-intensive, but also increases the work risk of the installer
