Description

Technical Field

[0001] The invention relates to the technical field of clear height measuring devices, and in particular to a clear height measuring device for construction engineering. Background Art

[0002] At a construction site, the net height of all buildings must be measured before the completion and acceptance of a construction project. This is a huge workload. In the past, surveyors had to squat repeatedly to measure using a laser rangefinder or manually use tools such as a tape measure to measure. In order to conveniently solve the shortcomings of laser rangefinders and manual tape measures, a construction project net height measurement device has been proposed in the prior art.

[0003] After searching, the patent document with publication number: CN219282876U discloses a device for measuring the net height of a construction project, including a device body and a positioning mechanism arranged on the outer wall of the device body, and the positioning mechanism includes a sliding component and a limiting component; the utility model is provided with a threaded slider on the outer wall of the device body. When the residential project is measured by the measuring device, in order to improve the stability of the device after the movement, the device can be moved to the required position, and the driving motor is turned on to drive the rotation of the threaded rod through the rotation of the synchronous belt. The rotation of the threaded rod drives the threaded slider to slide relatively along the inner wall of the fixed groove. The sliding of the threaded slider limits the universal roller through the positioning groove, so as to prevent the universal roller from being offset after the universal roller is moved, so as to realize the control operation of improving the stability of the device during measurement when the measuring device is used for mobile measurement.
