Surveying instrument for field engineering survey

Abstract

The invention provides a surveying instrument for field engineering survey. The surveying instrument comprises a fixing mechanism, a protection mechanism and a moving mechanism, the fixing mechanism comprises a lower protection shell, a clamping groove, an upper protection shell, a first telescopic rod and a first spring, the lower protection shell is rotationally connected with the upper protection shell, the clamping groove is fixedly connected with the surface of the lower protection shell, a first sliding groove is fixedly connected with the surface of the upper protection shell and slidably connected with a clamping plate, one end of the first telescopic rod is fixedly connected with the surface of the first sliding groove, the other end of the first telescopic rod is fixedly connected with the surface of the clamping plate, one end of the first spring is fixedly connected with the surface of the first sliding groove, and the other end of the first spring is fixedly connected with the surface of the clamping plate. A fourth telescopic rod and a fifth spring are used for telescopic damping in the moving process, meanwhile, a second telescopic rod, a second spring, a third telescopic rod and a third spring are used for telescopic damping, the instrument is protected, and it is guaranteed that the instrument is not damaged in the moving process.

Description

technical field [0001] The invention relates to a surveying and mapping instrument, in particular to a surveying and mapping instrument for field engineering survey. Background technique [0002] The surveying and mapping instrument is a high-tech measuring instrument integrating light, machinery and electricity. It is a surveying and mapping instrument system integrating the functions of measuring horizontal angle, vertical angle, distance and height difference. It is replaced by a photoelectric scanning dial, and the manual optical micrometer readings are replaced by automatic recording and display readings, which simplifies the angle measurement operation and avoids the occurrence of reading errors. Not damaged during movement. [0003] The existing storage boxes for surveying and plotting instruments only support the storage function and lack protection measures, which will cause damage to the instrument when it is carried and moved. Moreover, the structure and function...

AI Technical Summary

Problems solved by technology

[0003] The existing storage boxes for surveying and plotting instruments only support the storage function and lack protection measures, which will cause damage to the instrument when it is carried and moved. Moreover, the structure and function are relatively simple, and the moving measures can only be carried by a separate hand, which increases the labor load of the carrying personnel.
