Hanging Vertical Displacement Measuring Device

Technical field:

The utility model relates to a measuring device, in particular to a hanging type vertical displacement measuring device.

Background technique:

In the field static load test of civil engineering structures, the vertical displacement measurement mainly uses mechanical, electrical and optical measurement methods. The current practice of mechanical measurement methods is usually to use the support system built on site to make the measuring rod of the instrument (dial indicator, dial indicator) contact vertically with the surface of the measuring point, and the displacement of the measuring point is directly transmitted to the instrument. The disadvantage of this method is that it is time-consuming and labor-intensive to build and disassemble the support system. During the measurement process, technicians need to climb on the shelf to take readings, which is time-consuming, laborious, and has certain safety hazards; while electrical and optical measurement methods often use electronic devices. The conversion of mechanical displacement into non-mechanical quantity can realize digital display manual reading and data computer collection. However, the operation of the two methods is relatively complicated, and there are specific requirements for the quality of personnel. It is not easy to master quickly and proficiently, and the instrument is inconvenient to carry and install.

In order to overcome the deficiencies of time-consuming and labor-intensive displacement measurement methods, inconvenient reading, complicated operation and difficult to master quickly and skillfully in the on-site static load test of civil engineering structures, the utility model provides a hanging type vertical static displacement measurement device, which does not use With the help of a special instrument support system, and on the premise of ensuring that the measurement accuracy meets the engineering requirements, it can also achieve convenient reading, easy and understandable operation, and convenient device portability and installation.

Invention content:
