Field positioning surveying and mapping support

Abstract

The invention discloses a field positioning surveying and mapping support. The field positioning surveying and mapping support comprises a mounting frame body and a surveying and mapping device. The surveying and mapping device is fixed to the center of the top face of the mounting frame body, three supporting legs distributed in the circumferential direction at equal intervals are arranged on thebottom face of the mounting frame body, a center shaft hollow rod fixedly connected with the mounting frame body is arranged in the center of the bottom face of the mounting frame body, a positioningrod is arranged at the bottom of the center shaft hollow rod, and a main threaded rod rotationally connected with the center shaft hollow rod is inserted into the center shaft hollow rod. As the device is provided with the positioning rod and the supporting rods which are lifted and put down through lifting driver, when the device is overall fixed, firstly, the positioning rod is inserted into adesignated position, then the supporting legs are adjusted, thus, adjusting work is greatly facilitated, in this way, the supporting effect is guaranteed, height adjusting work at the earlier stage isfacilitated, a conventional single supporting leg adjusting manner is avoided, and surveying and mapping work can be rapidly carried out.

Description

technical field [0001] The invention relates to surveying and mapping technology, in particular to a field positioning surveying and mapping bracket. Background technique [0002] Surveying and mapping is surveying and drawing, which refers to the measurement, collection and drawing of the shape, size, spatial location and attributes of natural geographical elements or surface artificial facilities. Surveying and mapping instruments are instruments and devices designed and manufactured for data acquisition, processing, and output for surveying and mapping operations. The surveying and mapping instrument plays a key role in surveying and mapping operations, but the support of the surveying and mapping instrument generally uses multiple independent swinging poles as supporting components, and novice or practice surveying and mapping instruments often need to be calibrated.

Problems solved by technology

[0003] Chinese patent announcement number CN209445016U is a kind of triangular support for surveying and mapping engineering, and CN208935739U is a kind of surveying and mapping instrument support for surveying and mapping. Similar to the existing technology, a tripod structure is used to support the surveying and mapping device. The stability of the triangular structure can ensure the accuracy of surveying and mapping. , to ensure the safety of the equipment, but when fixing, it is necessary to pre-adjust the angle of the triangular bracket before it can be installed stably. In the field, it is often not like the smooth road in the city. It is very inconvenient to ensure the required measurement angle and height only after one adjustment.
