Embodiment 1

[0030] A surveying instrument fixing device for engineering surveying and mapping, such as Figure 1-4 As shown, the fixed chassis 3 is included, and the bottom of the fixed chassis 3 is provided with three first holes, and the bottoms of the three first holes are fixed with vertically arranged telescopic connecting rods 2 by bolts, and the bottom of the telescopic connecting rods 2 is passed through the bolts. Rotate and fix the fixed base 1 that is arranged horizontally, the top position of the fixed chassis 3 is fixed with the fixed top platform 4 that vertically arranges by bolt, the bottom of the fixed top platform 4 is fixed with the installation chassis 17 that vertically arranges, and the fixed top platform 4 The top is provided with a vertically arranged rotation groove 5. A horizontally arranged calibration air pump 18 is fixed in the middle of the bottom inner wall of the installation cabinet 17. The bottom of the fixed base 1 is provided with a sliding groove, and t...

Embodiment 2

[0034] A surveying instrument fixing device for engineering surveying and mapping, such as Figure 1-5 As shown, the top inner wall of the clamping top seat 6 is located at the inner wall of the clamping groove 7 and is fixed with a horizontally arranged ejection fixing plate 21, and the bottom of the ejection fixing plate 21 is fixed with a limit spring, and the bottom of the limit spring is in line with the clamping The bottom inner wall of the top seat 6 is connected.

[0035] When this embodiment is in use, in Embodiment 2, on the basis of Embodiment 1, a horizontal ejection fixing plate 21 is fixed at the bottom of the engaging groove 7, and the bottom of the ejecting fixing plate 21 is connected with the locking A limit spring is fixed between the inner walls of the top seat 6, and the ejection fixing plate 21 on the top can be ejected and fixed with the fixed surveying and mapping instrument, so that the fixing is more stable.

Abstract

The invention belongs to the technical field of engineering surveying and mapping, particularly relates to a surveying instrument fixing device for engineering surveying and mapping, and provides thefollowing scheme for solving the problem that a fixing device provided in the background art is horizontal in adjustment: the surveying instrument fixing device comprises a fixing chassis, three firstholes are formed in the bottom of the fixing chassis, vertically-arranged telescopic connecting rods are rotationally fixed to the bottoms of the three first holes through bolts, a horizontally-arranged fixing base is rotationally fixed to the bottoms of the telescopic connecting rods through bolts, and a vertically-arranged fixing top table is fixed to the top of the fixing chassis through bolts. According to the surveying instrument fixing device, careful levelness identification can be carried out through swinging of a three-axis stability sensor arranged inside and pulling of a calibration spring arranged at the top, and through inflation and deflation of a calibration inflator pump arranged at the bottom, inflation and deflation adjustment can be carried out on three calibration airbags arranged at the bottom respectively, so that the surveying instrument fixing device can be fixed horizontally and stably, and horizontal adjustment of the surveying instrument device in complex terrains is facilitated.

Description

technical field [0001] The invention relates to the technical field of engineering surveying and mapping, in particular to a fixing device for a surveying instrument for engineering surveying and mapping. Background technique [0002] Surveying and mapping engineering is a major that collects, processes, analyzes, expresses and applies spatial information. This major cultivates the basic theoretical and technical knowledge of spatial positioning, information science and computer science, and studies the use of these technologies to determine the shape of the earth and other stars, the three-dimensional characteristics of buildings (structures) and their relationship with the designated reference system, The earth's gravity field and its internal physical characteristics, the characteristics of moving objects and their multidimensional parameters, and the basic theories and methods for the application of these technologies in engineering, industry and human life. [0003] In...
