Auxiliary device convenient to move and fix for geographic surveying and mapping

Abstract

The invention discloses an auxiliary device convenient to move and fix for geographic surveying and mapping, and relates to the technical field of surveying and mapping devices. The auxiliary device comprises a clamping mechanism, a supporting plate and supporting legs; roller wheel frames are arranged at the positions, close to the lower ends, of the supporting legs, the roller wheel frames comprise first fixtures, roller wheels and linkage strips, the roller wheels are rotatably connected to one ends of the cavities of the first fixtures, and openings are formed in the other ends of the cavities of the first fixtures; second fixtures are arranged on the supporting legs corresponding to the roller wheel frames, strip-shaped pushing grooves are formed in the side parts of the two sides ofthe second fixtures, limiting clamping columns are arranged in the strip-shaped pushing grooves, the outer ends of the limiting clamping columns are hinged to one ends of the linkage strips, and the other ends of the linkage strips are hinged to the side parts of the first fixtures. The geographic surveying and mapping device is ingenious and flexible in structural design, practical and reliable,by additionally arranging the roller wheel frames on the supporting legs, the surveying and mapping instrument auxiliary device can be freely switched in two states of moving and using and fixing, theroller wheel frames do not occupy space and are convenient to use.

Description

Technical field [0001] The invention belongs to the technical field of surveying and mapping devices, and specifically relates to an auxiliary device for geographic surveying and mapping that is convenient to move and fix. Background technique [0002] As we all know, the surveying and mapping device is an auxiliary device for surveying and mapping the geography, which is widely used in the field of surveying and mapping; the existing surveying and mapping device includes a bracket and a surveying instrument. The bracket includes a placement plate and legs. The three sets of outriggers are respectively hinged on the left front side, left rear side and the rear end of the bottom of the placement plate, and the surveying instrument is set on the top of the placement plate; when this kind of surveying and mapping device is used, it only needs to be placed in the surveying area, and then according to the ground The flatness adjusts the position of the three sets of outriggers so that...

[0002] As we all know, a surveying and mapping device is an auxiliary device for surveying and mapping geography, and it is widely used in the field of surveying and mapping; group, and the three sets of outriggers are respectively hinged on the left front side, left rear side and rear end of the bottom of the placement board, and the surveying instrument is set on the top of the placement board; Flatness Adjust the positions of the three sets of outriggers so that the placement board is placed horizontally. During the adjustment process, check the adjustment results through the surveying instrument, and then use the surveying instrument to perform surveying and mapping; when using this surveying device, it is found that the surveying instrument can only be installed At the top of the bracket matched with it, the adaptability is poor, and the use limitation is high; and the existing surveying instrument auxiliary bracket device has a large volume and weight, and it is relatively laborious to move. It is used to move on the auxiliary support device, but the existence of the mobile roller also brings the unstable defect to the auxiliary support device of the surveying instrument, so it needs to be improved for the existing auxiliary support device of the surveying instrument
