A Distance Measuring Vehicle with Straight Track Monitoring Function

Abstract

The invention relates to a distance measurement trolley with a linear track monitoring function. A left early-warning lamp and a right early-warning lamp are arranged at two ends of a front wheel bracket respectively, a guide block is horizontally arranged on a distance measurement wheel connection member, a left projection and a right projection are horizontally arranged in the middle of a block, the guide block abuts to the middle of the block and is located between the left projection and the right projection, a left electric contact piece is arranged on the left projection, a right electric contact piece is arranged on the right projection, an electric contact block is disposed in the middle of the guide block, the left electric contact piece is connected with the right early-warning lamp through a wire, the right electric contact piece is connected with the left early-warning lamp through a wire, and the electric contact block is connected with a battery through a wire to be respectively connected with the left early-warning lamp and the right early-warning lamp. Compared with distance measurement trolleys in the prior art, the distance measurement trolley has the advantages that the defect that pushing distance measurement of the distance measurement trolleys cannot guarantee linear tracks is overcome; linear pushing of the distance measurement trolley in the process of pushing distance measurement can be real-timely monitored, and accuracy of distance measurement is improved.

Description

technical field [0001] The invention relates to the technical field of distance-measuring vehicles, in particular to a distance-measuring vehicle with a linear track monitoring function. Background technique [0002] At present, the use of distance measuring vehicles is very common, mainly used in fields such as construction distance measurement and intelligent transportation design. The distance measuring vehicle is used as a convenient measuring tool. It mainly relies on the circumference of the wheel to measure the distance, and then sends the corresponding data to the electronic display table for display. It is widely used in long-distance and large-scale ranging work. There are also a lot of improved patents for distance measuring vehicles, and many technical solutions have been proposed, all of which are aimed at improving the ranging accuracy of distance measuring vehicles. For example: the patent number is 201420016424, and the name is a utility model patent for a d...

Problems solved by technology

However, these technologies have a common problem in actual use, that is, there is no guarantee that the distance measuring vehicle will always be pushed along a straight line.

[0003] In the actual use of the distance measuring vehicle, because it is a field operation, most of them do not have marking lines for the distance measuring vehicle to use as a straight line reference, and often the distance measuring vehicle drifts unknowingly during the promotion process.

Especially during long-distance measurement, the distance measuring vehicle is prone to small-scale deviation after going through bumps. This deviation is difficult to find in the process of distance measurement, which eventually leads to errors and inaccuracies in the measured distance data.
