Abstract
The utility model provides a device for adjusting the initial installation value of a vibratory string type strain gauge. The device comprises a vibratory string type sensor and an adjusting unit, the adjusting unit comprises a connecting rack and a fine tuning bolt, the connecting rack is connected with the vibratory string type sensor, the connecting rack is provided with a fine tuning bolt hole, the fine tuning bolt is placed in the fine tuning bolt hole and can move in the fine tuning bolt hole, and the fine tuning bolt can make contact with or be separated from the moving end of the vibratory string type sensor. The device provided by the utility model has the advantages of small size, convenience in carrying and adjustment and simple structure; and when the required initial value is set, the free end can be fixed needless of manual pressing.
Description
Technical field
The utility model relates to calibration apparatus, relates in particular to vibrating string extensometer initial value regulating device is installed.
Background technology
Vibrating string extensometer has the advantages such as good stability, antijamming capability is strong, image data is convenient, is more and more widely used in the monitoring of Important Project.Vibrating string extensometer is generally used for measuring the strain of body structure surface.While installation, conventionally adopt the mode of welded and installed piece on steel construction.After mounting blocks fix in position, pull down mounting rod, load onto instrument and coil, by instrument stiff end screw-driving (bore sharp gib screw should be screwed to instrument have in the groove of groove end block).With readout instrument monitoring, instrument is regulated.The common range of readings of strainometer is 400~1200(word), if Instrument Design is used for measuring stretching strain, can, by inwardly light pressure of strainometer movable end, reading be adjusted to 650 left and right.After adjustment, free end is fixed.
Prior art problem and defect are described: 1. can only be artificial strainometer movable end be gently pressed with hand, cannot quantize.2. owing to being that movable end is pressed in people's have gentle hands, can not accurately control reading until secure free end.
