Abstract

The invention discloses a centering device for geodetic surveying. A support joint connected with a geodetic surveying device is arranged at the upper end of a centering rod; a tripod support leg structure is arranged at the lower end of the centering rod; a support seat for supporting a circular level is further arranged on the sidewall of the centering rod; and the tripod support leg structure comprises a first support leg, a second support leg and a third support leg which are provided with upper ends hinged with the sidewall of the lower end of the centering rod separately. The centering device for geodetic surveying further comprises an annular slide seat slidably sleeving the centering rod, wherein the annular slide seat is hinged to the three support legs through push-pull rods separately; an electric push rod is arranged at the tail end of each support leg, and a pressure sensor is arranged on a push rod head of each electric push rod; the pressure sensors are connected with amicroprocessor separately; and the microprocessor is further connected with a control button group controlling the electric push rods. The centering device for geodetic surveying is simple in operation process, high in operation automation degree, and capable of effectively levelling and conveniently keeping during centering adjustment, so that the working efficiency of the geodetic surveying isgreatly increased.

Description

technical field [0001] The invention relates to the field of geodetic surveying equipment, in particular to a centering device for geodetic surveying. Background technique [0002] The centering of conventional geodetic observations is centered using plummets, optical plummets or lasers. When observing, open the telescopic tripod and set it above the point to be observed, and fix the base on the tripod with a connecting screw to perform centering and leveling, so that the centering accuracy is not high and the image observation accuracy is not high. In the process of adjusting the centering device, the operation is cumbersome, and it is difficult to effectively level. Since the operation is usually performed by a single person, it is difficult to operate, and it is difficult to complete the centering adjustment conveniently and efficiently, which affects the measurement work efficiency. Contents of the invention [0003] The object of the present invention is to overcome ...
