Mechanical supporting device for civil engineering surveying and mapping

Abstract

The invention provides a mechanical supporting device for civil engineering surveying and mapping. The problem in the prior art that when whether the edge of a house or a foundation pit is level or not is measured, one support leg suspends, and the measurement effect cannot be reached is solved. The mechanical supporting device comprises a base, a support leg slide rail is connected to the outer edge of the base, support leg slide covers slide on the support leg slide rail, support legs are hinged to the lower ends of the support leg slide covers, and telescopic support legs are slidably installed in the support legs; the faces, facing the central line of the base, of the support legs are provided with linkage rod slide grooves respectively, linkage rods which penetrate through the corresponding linkage rod slide grooves and are hollow inside are hinged to the tops of the telescopic support legs respectively, linkage rod slide covers are hinged to the bottom faces of the other ends ofthe linkage rods respectively, and the other ends of the linkage rod slide covers are slidably installed on a linkage disc which is located below the base and is coaxial to the base. According to themechanical supporting device, through the cooperation of the support leg slide rail and the three support leg slide covers, the three support legs installed on the three support leg slide covers can be independently adjusted, and when one support leg suspends, the support leg can slide to change the position.

Description

technical field [0001] The invention relates to the technical field of civil engineering surveying and mapping, in particular to a mechanical support device for civil engineering surveying and mapping. Background technique [0002] Civil surveying and mapping engineering, that is, measuring various information of space and the earth and drawing various topographic maps, takes the shape, size, and gravity field of the earth and other planets as the research object. Land features, geomorphology and underground geological structure, hydrology, mineral deposits, etc., such as mountains, rivers, houses, roads, vegetation, etc., usually before developing a piece of land or carrying out large-scale engineering construction, surveying and mapping engineers must measure and draw topographic maps, and provide other information Therefore, the work of surveying and mapping is very important. [0003] A surveying and mapping instrument is an instrument used for collecting, processing an...

Problems solved by technology

[0009] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a mechanical support device for civil engineering surveying and mapping, which effectively solves the following difficult problems that cannot be overcome in the prior art: 1. When measuring whether the edge of a house or foundation pit is horizontal , there will be one leg suspended in the air, if the tripod is turned as a whole, the measuring instrument will be offset from the edge of the house or foundation pit, and the measurement effect will not be achieved; The height of one outrigger needs to be fine-tuned on the three outriggers in turn, which is cumbersome to operate; 3. When the measurement environment is in soft soil or sandy ground, the outriggers of the tripod will sink, which will make the measuring instrument deflect, thus affecting the measurement accuracy. question
