Leveling support for territorial resource land surveying instrument

Abstract

The invention provides a leveling support for a territorial resource land surveying instrument. The leveling support comprises a fixing base which is installed on the top of a supporting rod. The lower end of the supporting rod penetrates a fixing plate and extends to the lower end of the bottom of the fixing plate. Screws are installed on the four corners of the fixing plate correspondingly. Thelower ends of the screws penetrate the fixing plate and extend to the lower end of the bottom of the fixing plate. A lifting table is installed on the top of the fixing base through a first hydraulicrod. A rotating disc is installed on the top of the lifting table through a rotating bearing. A first limiting pin hole is formed in the top of the rotating disc. Fixing lugs are installed on the leftside and the right side of the bottom of an adjusting base correspondingly. The fixing lugs are in transmission connection with a second hydraulic rod through the rotating disc. According to the leveling support, when inserted into soil, the leveling support is more stable, the height of the lifting table can be adjusted, the direction of the adjusting base can be adjusted, the horizontal state of the adjusting base can be adjusted conveniently, the balance state of the adjusting base can be adjusted, and meanwhile the surveying instrument can be prevented from sliding off from the adjustingplate.

Description

technical field [0001] The invention belongs to the technical field of leveling brackets, and in particular relates to a leveling bracket for a land surveying and mapping instrument for land resources. Background technique [0002] Various surveying and mapping instruments are most commonly used in land surveying and mapping, including spirit levels, levels, theodolites, rangefinders, and total stations. Different surveying instruments have different working principles and usage methods, but there is one thing that must be done before all instruments are used, that is, leveling. The data measured by the instrument without leveling are also inaccurate. Generally speaking, the surveying and mapping instrument itself will have its own leveling device, which can perform slight level adjustments. However, when conducting field land surveying and mapping operations, the terrain is extremely complex, and surveyors often need to perform surveying and mapping operations on some ste...

Problems solved by technology

However, when conducting field land surveying and mapping operations, the terrain is extremely complex, and surveyors often need to perform surveying and mapping operations on some steep slopes and slopes. Need, surveying and mapping personnel often need to excavate a plane on site to ensure the smooth progress of the surveying and mapping operation, which to a certain extent has brought great obstacles and difficulties to the staff of land surveying and mapping
