Description

Technical Field

[0001] The utility model relates to the field of arch frame measurement, in particular to an arch frame measuring instrument. Background Art

[0002] Inclined shafts and headings in mines, weathered bedrock sections of headings, and unstable strata usually adopt secondary support. The first support usually adopts arch frame support. Arch frame support can effectively ensure the safety of the working face. When installing the arch frame, it is necessary to detect its distance, which requires the use of an arch frame measuring instrument.

[0003] Common arch frame measuring instruments only include the function of distance detection and can detect the spacing of arch frames, but lack the functions of quick disassembly and assembly and level detection. They cannot ensure the quick disassembly and assembly of the arch frame measuring instrument and cannot ensure the levelness of the arch frame measuring instrument after installation. It is easy to have problems such as cumbersome steps during disassembly and assembly and deviation of the horizontal position after installation, affecting the convenience of disassembly and assembly and the measurement accuracy.

[0004] Therefore, aiming at the lack of functions of quick disassembly and assembly and level detection in the above-mentioned arch frame measuring instrument, an arch frame measuring instrument can be designed. By setting two telescopic rods connected to strong magnetic blocks, and then pushing the installation frame downward from above the support pipe, the two arc-shaped clamping plates cooperate to clamp the support pipe to complete the installation. After the arch frame measuring instrument is installed, it is compared with the alcohol in the horizontal groove according to the horizontal line to judge the levelness of the installed arch frame measuring instrument, which is convenient for timely adjustment to ensure the quick disassembly and assembly of the arch frame measuring instrument and the levelness of the arch frame measuring instrument after installation. Summary of the Utility Model

[0005] In order to overcome the problems of common arch frame measuring instruments, which lack the functions of quick disassembly and assembly and level detection, cannot ensure the quick disassembly and assembly of the arch frame measuring instrument and cannot ensure the levelness of the arch frame measuring instrument after installation, and are prone to cumbersome steps during disassembly and assembly and deviation of the horizontal position after installation, affecting the convenience of disassembly and assembly and the measurement accuracy.

[0006] The technical solution of the utility model is as follows: The arch frame measuring instrument includes a support pipe; it also includes an installation frame, a battery box, a single-chip microcomputer, arc-shaped clamping plates, a guide plate, an anti-slip groove, a spring, and a telescopic rod.

Then, the two telescopic rods are pulled out from the interior of the support tube, and the ends of the two telescopic rods away from the mounting frame are inserted into the interior of the mounting holes.

[0011] Preferably, four support rods are provided at the four corners of the top of the installation frame. At the top ends of the four support rods, there is a laser assembly board.
