Surveying and mapping bracket device capable of being stably supported on flat road surface

Abstract

The invention discloses a surveying and mapping bracket device capable of being stably supported on a flat road surface. The surveying and mapping bracket device capable of being stably supported on the flat road surface comprises a base; a supporting rod is fixedly arranged at the top end of the base; three supporting sliding block sliding grooves with openings backing onto a center shaft of the supporting rod are evenly and fixedly formed in the supporting rod; a connecting balance weight mechanism is arranged at the position of each supporting sliding block sliding groove; three face expanding blocks are evenly and magnetically connected to the side wall of the base; anti-skid bottom plate blocks are fixedly arranged at the bottom ends of the face expanding blocks; hinge joint semispherical grooves with upward openings are fixedly formed in the top ends of the face expanding blocks; the hinge joint semispherical grooves are hinged to hinge joint semispheres; and hinge joint sliding rod sliding grooves with downward openings are fixedly formed in the bottom ends of the hinge joint semispheres. According to the surveying and mapping bracket device capable of being stably supported on the flat road surface, the contact area and the friction factor between the three sharp bottoms at the bottom end of the surveying and mapping bracket device and the ground can be automatically increased according to requirements, distance transportation of balancing weights can be automatically conducted according to the adjusted angle, and therefore supporting of a surveying and mapping bracket is further stabilized.

Description

Technical field[0001]The present invention relates to the field of surveying and mapping, and in particular, a mapping bracket device capable of stabilizing supporting on a flat pavement.Background technique[0002]Surveying and mapping is based on the measurement and drawing. Based on computer technology, photoelectric technology, network communication technology, space science, information science is based. The global navigation satellite positioning system, remote sensing, geographic information system is the core, and selects the existing feature of the ground. Point and boundaries and through measurement methods to reflect graphics and location information reflecting the status of the ground, for engineering construction, planning and design, and administrative management.[0003]At present, the bottom end of the test scaffolding device is fixed to the ground by three scorpions, which is very stable for soft ground and rough surface, but for smooth and hard, the contact area is too...

AI Technical Summary

Problems solved by technology

[0003] The bottom of the current surveying and mapping support device is fixed on the ground by three pointed bottoms, which is very stable for soft and rough ground, but for smooth and hard ground, the contact area of ​​the pointed bottom is too small. It is easy to slip and affect the surveying and mapping work, and it is not stable enough
