Abstract

A positioning fixture and a hardcover tool for a vibrating wire strain sensor with a circular cross-section surface. The hardcover tool includes a diamond-shaped stretchable net and a plurality of installation fixtures. Adaptive vertical support, the upper end of the vertical support is provided with an upper support block, and the upper support block is provided with an upper pad clamping groove for clamping pad blocks, and the lower end of the vertical support is provided with a lower support block, and the lower The supporting block is provided with a lower cushion block clamping groove for clamping the cushion block. The installation fixtures are connected to the diamond-shaped stretchable net at equal intervals in the transverse direction, and each installation fixture is connected to a hinge point on the diamond-shaped stretchable net. The lower end of the vertical support is provided with a lower support block, and the lower support block is provided with a lower pad clamping groove for clamping the pad block. The positioning of the invention is fast and accurate, and a single person can install the vibrating wire strain sensor, which greatly reduces construction costs, reduces the risk of complex operations at high altitudes, and improves 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...
