Description

Technical Field

[0001] This utility model belongs to the field of surveying equipment technology, specifically relating to a surveying instrument suitable for complex terrain. Background Technology

[0002] A surveying instrument is a precision measuring instrument that integrates optical, mechanical, and electronic technologies. It can capture images of workpieces into a computer for processing and display on a screen, facilitating direct photo archiving, surface observation, measurement, and drawing operations. This instrument is widely used in land surveying, construction engineering, urban planning, and geographic information systems, among other fields.

[0003] To ensure the stability of the surveying instrument during the measurement process, it is usually necessary to use a tripod for auxiliary support. However, surveying operations often involve complex terrain, such as mountains, slopes, fields, puddles, and concrete surfaces. Although existing tripods can provide support, they cannot quickly help the surveying instrument find a horizontal plane. This not only reduces operational efficiency but may also affect the accuracy of the surveying results. Therefore, we have proposed a surveying instrument suitable for complex terrain to solve the above problems. Utility Model Content

[0030] Base 100 and three foot supports 102 combination can form a tripod, it is convenient to support surveying instrument body 101, and surveying instrument body 101 can be fixed by bolt installation on the upper end of base 100;Surveying instrument body 101 can take photograph and archive, surface observation, measurement and drawing;When three foot supports 102 are unfolded or folded, linkage assembly can make the same angle of rotation, through the extension of extension assembly, the effective length of foot support 102 can be lengthened, so that the tripod can be more stably installed on the rugged ground, through the gravity of pull wire 107 and conical lead block 108, staff can observe the position of conical lead block 108 in cavity 105, so as to adjust the horizontal state of base 100, thereby improving the work efficiency of staff.

[0031] When staff installs surveying instrument: first, three foot supports 102 are unfolded, because of the limitation of linkage assembly, so each foot support 102 rotates at a consistent angle, so that the balance of entire base 100 can be guaranteed, then, the lower end of three foot supports 102 is contacted with ground, because of different terrain, foot support 102 can be lengthened through extension assembly until each foot support 102 is contacted with ground, so that base 100 can be installed, then, surveying instrument body 101 is installed on the upper end of base 100, finally, the situation of conical lead block 108 in cavity 105 can be observed through each rectangular groove 106,

[0032] S1: when conical lead block 108 is suspended in the inside of cavity 105, surveying instrument body 101 installed at this time is in horizontal state, so that the data surveyed is more accurate;
