Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly the measurement constructional device of a kind of track three-dimensional coordinate accurate measurement.
Background technology
Using high-speed railway accurate measurement equipment to railroad track construct adjustment, route survey and final acceptance of construction etc., is the important change of contemporary railroad survey technology and method.It has changed the lower traditional-handwork operating type of precision thus, and the content that makes railroad survey more comprehensively, automaticity and certainty of measurement be higher.Its measuring principle of fine measuring instrument that is used for the high-speed railway operation maintenance at present all is to adopt one-point measurement, and the measurement efficient of this metering system can't satisfy the requirement of works department, therefore, realize that continuous measurement is the main target of high-speed railway maintenance research.During at how much state maintenances of high speed railway track, how the present situation that personnel are few, workload is big, the working time is limited improves detection efficiency, needs to explore some new technologies, new method.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy to use at the deficiencies in the prior art, can go out fast, measure accurately and efficiently orbit geometry parameter, the measurement mechanism of the track three-dimensional coordinate accurate measurement of giving security for traffic safety.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The measurement mechanism of a kind of track three-dimensional coordinate accurate measurement, comprise installation support in orbit, the part that described support contacts with track is provided with running gear and positioner, described support comprises the longeron consistent with track cloth set direction and across the crossbeam between two tracks, described crossbeam is connected with described longeron, on the longeron of described support inertia system is installed, on the described crossbeam prism is installed.
Gauge measurement mechanism and level measurement device also are installed on the described crossbeam.
Also comprise installation delivery dolly in orbit, on the described delivery dolly total powerstation is installed.
Described support is H shape or T shape.
Described crossbeam is installed in the middle part of described longeron, and described crossbeam and described longeron junction are provided with structural strength and the stable location-plate that strengthens between crossbeam and the longeron.
