Positioning device for highway engineering surveying and mapping

Abstract

The invention discloses a positioning device for highway engineering surveying and mapping. The positioning device comprises a first square frame, a lifting mechanism is arranged in the first square frame, stabilizing mechanisms are arranged at the lower end of the first square frame, a position adjusting mechanism is arranged on the first square frame and comprises a second square frame, the second square frame is located above the first square frame, a third square frame is arranged in the second square frame and is slidably connected with sliding grooves formed in the two sides of the inner wall of the second square frame, a first lead screw is arranged in the third square frame, a connecting rod is in threaded connection with the first lead screw, a support seat is arranged at one end of the connecting rod, a sliding rod is arranged in the third square frame, a sliding block is arranged on the sliding rod and is connected with the support seat, and a surveying and mapping instrument is arranged on the support seat. According to the positioning device for the highway engineering surveying and mapping, the surveying and mapping instrument can be driven by the first lead screw to move forwards and backwards and can be driven by a second lead screw to move leftwards and rightwards, position adjusting is performed on the surveying and mapping instrument, point fixing of the surveying and mapping instrument is facilitated, and the situation that the surveying and mapping instrument is difficult to fix by moving a triangular support and the falling risk of the instrument is easily increased is prevented.

Description

technical field [0001] The invention belongs to the technical field of highway engineering, in particular to a positioning device for highway engineering surveying and mapping. Background technique [0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, management, etc. of highway structures. Highway engineering structures include: roadbeds, pavements, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities , as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. [0003] At present, in highway engineering surveying and mapping, a tripod is used to install the surveying instrument. In the process of fixing the point, the tripod needs to be moved until the laser point irradiated by the surveying instrument on the ground coincides with the fixed point on the ground. During this process, the moving tripod drives the surv...
