Abstract

The invention discloses an engineering surveying instrument positioning device. The engineering surveying instrument positioning device comprises a bottom plate, a supporting cylinder and a placementplate, the lower end of the bottom plate is rotationally connected with the supporting cylinder through a bearing seat, an annular cavity is formed in the middle of the bottom plate in a penetrating mode, a ball seat is movably connected into the annular cavity in a matched mode, the upper end of the ball seat is horizontally and fixedly connected with the placement plate, the lower end of the ball seat is vertically and fixedly connected with a suspender, the tail end, away from the ball seat, of the suspender is fixedly connected with a balance weight lead block, a plurality of groups of limiting clamps used for movably pressing the ball seat tight are connected to a portion on the bottom plate and located on the periphery of the annular cavity. According to the engineering surveying instrument positioning device, the tail end of the suspender can be kept vertically downward through the balance weight lead block, meanwhile, the placement plate can be driven to be kept horizontal through the ball seat, and therefore a surveying instrument can be kept horizontal under any condition, the surveying accuracy is effectively guaranteed, and effective limitation can be carried out on theball seat through the limiting clamps, so that deviation caused by movement of the ball seat in the annular cavity during installation of the surveying instrument is avoided.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a positioning device for an engineering surveying and mapping instrument. Background technique [0002] Surveying and mapping is literally understood as surveying and drawing. It is based on computer technology, photoelectric technology, network communication technology, space science, and information science. It is based on global navigation satellite positioning system (GNSS), remote sensing (RS), and geographic information system (GIS). The technical core is to select the existing feature points and boundaries on the ground and obtain the graphics and position information reflecting the current situation of the ground through measurement means for engineering construction, planning and design and administrative management. [0003] In the prior art, the engineering surveying instrument needs to adjust the active horizontal reference system through parameters during use, or...
