Abstract

The invention provides a circular cross section surface vibrating wire type strain sensor positioning clamp and a precise installation tool. The precise installation tool includes a rhombic stretchable net and a plurality of installation clamps, the installation clamps include vertical supports made of magnetic materials and suitable for the length of strain sensors, the upper ends of the vertical supports are provided with upper supporting blocks, the upper supporting blocks are provided with upper cushion block clamping and fixing grooves for clamping and fixing cushion blocks, the lower ends of the vertical supports are provided with lower supporting blocks, and the lower supporting blocks are provided with lower cushion block clamping and fixing grooves for clamping and fixing cushion blocks. The installation clamps are transversely connected to the stretchable net at equal intervals, and each installation clamp is connected to a hinge point on the rhombic stretchable net. The circular cross section surface vibrating wire type strain sensor positioning clamp provided by the invention is rapid and accurate in positioning, and a single person can install vibrating wire type strain sensors, thereby greatly reducing construction cost, reducing risks of high-altitude complex operation, and improving installation efficiency.

Description

technical field [0001] The invention relates to the field of installation of strain sensors, in particular to a positioning fixture and a hardcover tool for vibrating wire strain sensors with circular cross-section surfaces. Background technique [0002] In the construction process of civil engineering and structural fields, it is necessary to monitor the average stress and strain of its key structural parts, and weld the vibrating wire strain sensor on the surface of the steel structure to measure the required technical parameters; its working principle is when the measured structure When the internal stress changes, the strain gauge feels the deformation synchronously, and the deformation is transferred to the vibrating wire through the front and rear end seats to change the stress of the vibrating wire, thereby changing the vibration frequency of the vibrating wire, and the electromagnetic coil excites the vibrating wire and measures its vibration Frequency, the frequency...
