Embodiment 2

[0025] see image 3 , in an embodiment of the present invention, a positioning device for an engineering surveying instrument. On the basis of Embodiment 1, the limit card 11 includes a rotating seat 13 fixedly connected to the bottom plate 1 and connected to the rotating seat through a rotating shaft 14 in rotation. The rotating rod 12 on 13, the end of the rotating rod 12 away from the rotating seat 13 is fixedly connected with an anti-slip block 15, the anti-slip block 15 is block rubber, and the anti-slip block 15 and the ball seat 5 are oppositely arranged The surface of the anti-slip block 15 and the ball seat 5 can be bonded by the rotation of the rotating rod 12, and multiple groups of ball seats 5 are pressed on the surface of the ball seat 5, which can prevent the rotation of the ball seat 5 by frictional force and ensure the stability of the placement plate 6. Level.

[0026] The rotating seat 13 is a "U"-shaped bent metal piece, the opening of the rotating seat 13...

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...
