Adopt the track three-dimensional constraining measurement mechanism of portable laser rangefinder
Technical field
The utility model relates to a kind of track three-dimensional constraining measurement mechanism, relates in particular to a kind of track three-dimensional constraining measurement mechanism that adopts the portable laser rangefinder.
Background technology
The existing line three-dimensional accurate measurement is a kind of existing line orbit measurement technical development thinking that the Ministry of Railways is fermenting.Before this, existing line adopts relative irregularity detection technique, has set up relevant industry standard and equipment system.And newly-built track has proposed and has progressively set up track three-dimensional localization measuring technique system in construction.But because existing line is operated under the line clear state, the track three-dimensional measurement technology transplant of adopting during directly with newly-built track is measured the tremendous influence that will be subjected to activity duration, efficient and cost to the maintenance of existing line, can't get the nod on engineering and implement.
Track three-dimensional localization measuring system is a kind of professional precision adjustment measurement system of developing at the non-fragment orbit construction survey, its core technology is to be benchmark (CP3) with track accurate measurement net, to have from motion tracking, to sight automatically and automatic measurement function, the high-precision total powerstation that can carry out Remote is an external sensor, three-dimensional coordinate by a prism point arranging on the total station survey absolute measurement dolly, by merging, can obtain the track centre three-dimensional coordinate with other internal sensor metrical informations of dolly.
The typical workflow of track three-dimensional localization measuring system is: total powerstation is established the station, fixed point or continuous pointwise are carried out three-dimensional measurement to track centre, station transfer, and total powerstation is established the station again, overlay segment is measured, and the fixed point of next round or continuous pointwise are carried out three-dimensional measurement to track centre ...
Existing line utilizes track stake etc. to carry out track control, can adopt some easy instruments such as tape measure, leveling ruler etc. to carry out manual measurement, but at present still the digitized existing line three-dimensional restriction of open report measure the dolly product.
Summary of the invention
The purpose of this utility model has been to provide a kind of track three-dimensional constraining measurement mechanism that adopts the portable laser rangefinder, and this device does not utilize total powerstation just can measure the three-dimensional coordinate of existing line, greatly reduces system cost.
The utility model is to realize like this, it comprises track detection car, level measurement device, orbit measurement device, constraint measurement pillar, laser range sensor, track restrained stake, it is along the line to it is characterized in that track restrained stake is arranged on railway track, lay track detection car on the railway track, connect level measurement device and gauge measurement mechanism on the track detection car respectively, one end of track detection car connects upright constraint and measures pillar, and the laser range sensor that connects a slip on the pillar is measured in constraint.
Constraint described in the utility model is measured pillar and is replaced by the constraint measuring oscillating bar that an end is hinged on the track detection car.
Constraint described in the utility model is measured pillar and is measured the swivel head replacement by the constraint of band angular measurement sensor.
Constraint described in the utility model is measured the pillar upper/lower terminal and is respectively connected a laser range sensor.
Technique effect of the present utility model is: do not need total powerstation, and compact conformation, simple to operate, be not subjected to the influence of surrounding environment, reduced complexity and the technical difficulty of measuring three-dimensional coordinate simultaneously.
