Description
Technical Field
The utility model relates to a laser rangefinder fixing device with adjustable remove belongs to the prefabricated construction measurement technical field of track roof beam.
Background
In the existing PC curve track beam construction measurement, the curve radius, the beam length and the ultrahigh slope rate of each roof beam are different, and the shapes are different. The allowable error of each technical parameter of the track beam is generally required to be controlled within +/-3 mm, and the process adjustment error is required to be controlled within 1.5 mm. When offset measurement is carried out on the transverse curvature of the curve track beam template, the measurement accuracy is influenced by the accuracy of a detection tool and a detection method, so that the reading error is large. Therefore, a measuring method capable of accurately measuring the distance in the process of detecting the transverse bending of each section of the template is needed to ensure the measuring accuracy. In the past, a total station is generally adopted to be erected at the end part of one side of a track beam for a long time to be matched with a tape measure or a tower ruler to measure the transverse offset distance of each section of a template, so that the instrument occupies a long time, the phenomena that a detection ruler cannot be horizontally placed and accurately masters the normal direction, the measurement ruler is bent and the like cause large errors in measurement distance, the precision requirement of the template cannot be met, and great influence is brought to the construction period.
SUMMERY OF THE UTILITY MODEL
The utility model provides a laser rangefinder fixing device with adjustable remove that uses in the horizontal crookedness of PC curve track beam mold board detects through the horizontal offset of each section of accurate measurement template, improves instrument rate of utilization, transverse distance detection precision and work efficiency, has shortened construction period.
The technical solution of the utility model is as follows:
a movable adjustable laser ranging fixing device comprises a laser range finder 1, a clamping seat 2, a fixed level bubble 3 and a slide rail 4; level bubble 3 is installed at cassette 2 top, and laser range finder 1 is installed in cassette 2. The device also comprises a slide rail 4, wherein the clamping seat 2 can be slidably arranged in the slide rail 4 and is fixed at a position to be measured in a limit screw sliding groove 6 through a limit screw 5.
The utility model has the advantages that:
the device has the advantages of stable structure, convenient disassembly, portability, independent operation and high precision; a plurality of sets can be manufactured at low cost, and multiple points can be used simultaneously; the method is suitable for measuring the transverse offset distance of the template in all bridge structures, improves the instrument utilization rate, the transverse distance detection precision and the working efficiency, shortens the construction period and has higher popularization value.
