Description

Technical Field

[0001] This utility model relates to the field of topographic surveying technology, and in particular to a multi-topographic surveying support. Background Technology

[0002] Topographic surveying refers to the work of creating topographic maps. This involves determining the projected positions and elevations of features and terrain on the Earth's surface onto a horizontal plane, reducing them to a certain scale, and then drawing them into topographic maps using symbols and annotations. Topographic mapping primarily employs aerial photogrammetry, utilizing aerial photographs mainly for indoor mapping. However, for smaller areas or topographic maps required for engineering construction, plane table surveying methods are used.

[0003] In field mapping, a plane table consists of a plane and an aiming device. The plane table is composed of a plotting board, a base, and a tripod; the aiming device consists of a telescope, a vertical circle, a support, and a ruler. Its function is similar to the aiming part of a theodolite, except that a direction line is drawn along the edge of the ruler on the plotting board to replace the horizontal circle reading of the theodolite. The plane table also has accessories such as a centering device, a level for leveling, and a long box compass for orientation. During mapping, using the points a and b already plotted on the plotting board corresponding to ground control points A and B, the plane table is placed at point B. Using b as the pole, the plane table is oriented along the BA direction. Then, the telescope is used to aim at the detail point C. The edge of the ruler passing through point b is the direction line pointing to point C. Next, use the stadia measurement method to determine the horizontal distance from point B to point C and the elevation of point C. According to the map scale, cut the corresponding length from point b along the edge of the ruler to obtain the plane position c of point C on the map, and record its elevation next to the point. Then, measure and draw point by point and station by station to draw the topographic map.

[0004] The engineering surveying support base disclosed in CN208185806U includes a base plate, a rod at the center of the bottom of the base plate, and stabilizing rods on the front, back, left, and right sides of the base plate. A stabilizing sleeve is fitted onto the bottom of each stabilizing rod, and a support spring is installed at the bottom of the inner cavity of the stabilizing sleeve, with the top of the support spring connected to the bottom of the stabilizing rod. A threaded rod extends longitudinally through the bottom of the base plate on all four sides, and a bearing seat is installed on the top of each threaded rod, with the top of the bearing seat connected to the bottom of the base. The base plate, rod, stabilizing rods, stabilizing sleeve, and base are all made of steel. This engineering surveying support base provides good support for the engineering surveying support, high stability, and prevents the support from wobbling, making it highly practical.

[0005] However, in actual use, it was found that the support could not always maintain a horizontal state when facing terrain with different slopes, which greatly reduced the accuracy of subsequent surveying by the surveying instrument. Furthermore, it was not convenient to adjust the height of the support according to the surveying needs, which greatly reduced the adjustability of the support. Therefore, we propose a multi-terrain surveying support to solve this problem. Utility Model Content

[0014] Preferably, a hydraulic telescopic rod is fixedly installed on the top of the support plate, the bottom end of the hydraulic telescopic rod penetrates the support plate and extends below it, and a cone head is fixedly installed on the bottom end of the hydraulic telescopic rod.

[0015] In this utility model, a multi-terrain mapping support is provided.

Furthermore, by controlling the extension length of the four hydraulic telescopic rods, the support plate can always remain horizontal on terrains with different slopes, thereby greatly improving the accuracy of subsequent mapping by the surveying instrument.

[0016] In this utility model, a multi-terrain mapping support is provided. The main motor output shaft rotates, driving the transmission worm gear and transmission worm wheel to mesh, thereby driving the rotating shaft to rotate.

The support plate 1 can support the rotating shaft 2, and the rotating shaft 2 can support the rotating disk 3. The rotation of the output shaft of the main motor 6 drives the transmission worm gear 7 and the transmission worm wheel 8 to mesh, thereby driving the rotating shaft 2 to rotate.
