Multifunctional surveying and mapping instrument

Abstract

The invention belongs to the technical field of surveying and mapping devices, and particularly discloses a multifunctional surveying and mapping instrument. The multifunctional surveying and mappinginstrument comprises a surveying and mapping instrument main body and a surveying and mapping bracket which is in spinning connection with the bottom end of the surveying and mapping instrument main body; the bottom ends of the surveying and mapping bracket are connected with supporting leg assemblies; each supporting leg assembly comprises a screw rod, an internal rotating sleeve, a cleaning hole, a supporting foot, an external rotating sleeve and a supporting leg, wherein the bottom end of each screw rod is welded with the corresponding supporting foot; the surface of each screw rod is in spinning connection with the corresponding internal rotating sleeve; each internal rotating sleeve is clamped to the interior of the corresponding supporting leg; the surface of each internal rotating sleeve is welded with a fixed ring; the multifunctional surveying and mapping instrument is provided with the supporting leg assemblies; the internal rotating sleeves are driven to rotate by rotating the external rotating sleeves by working personnel, so that the screw rods and the internal rotating sleeves are overturned to achieve the purposes of rotating, regulating, ascending and descending thesupporting legs up and down by the screw rods; and the supporting legs are rotated and inserted into the ground, so that the problem that the multifunctional surveying and mapping instrument is inconvenient to fix in rugged hard soil is solved.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping devices, and in particular relates to a multifunctional surveying and mapping instrument. 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 photoelectric scanning dial, and the manual optical micrometer reading is replaced by automatic recording and display reading, which simplifies the operation of angle measurement and avoids the occurrence of reading error. [0003] There are following problems in existing technology: [0004] When the existing multifunctional surveying and mapping instruments are in use, the surveying and mapping instruments are generally installed on the tripod for fixed surveying and mapping.

Problems solved by technology

[0004] When the existing multifunctional surveying and mapping instruments are in use, the surveying and mapping instruments are generally installed on the tripod for fixed surveying and mapping. Before surveying and mapping, the surveying and mapping tripod needs to be fixed. It is used to insert into the dirt ground for fixing, but in the hard and uneven dirt ground, it takes a lot of effort for the staff to fix the tripod into the dirt ground
