Description
Technical field
The utility model relates to orbit measurement field, in particular to a kind of track geometry status measures trolley.
Background technique
With the continuous progress of science and technology, the speed of train also rapidly improves therewith, and then the requirement to running rail is also got over
Come higher.If the distance between two tracks cannot be guaranteed identical always, train extremely easy generation in the process of moving
The phenomenon that derailing, causes the generation of safety accident, therefore whether is maintained at same to the distance between track before train trial operation
The detection of one distance seems most important.
Utility model content
The purpose of the utility model is to provide a kind of track geometry status to measure trolley, its advantage is that: it ensure that two
The measurement accuracy of range error between track, reduce because the distance between two tracks are excessive make train trial operation when hair
Raw derailment occurring.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of track geometry status
Measure trolley, including two groups of support frames, the both ends of support frame as described above along its length are connected with a bracket, in the bracket
