Abstract
The utility model provides a vehicle-mounted on-line detection device for a subway third rail, which comprises an installation bracket connected on a bogie of a detecting car body, a left axle casing cover,a right axle casing cover, six laser ranging sensors fixedly installed on the installation bracket, wherein, two laser ranging sensors are installed in the middle of the installation bracket, so that the emitting surfaces thereof faces toward the inner side of a running rail; two other laser ranging sensors are respectively installed at two ends of the bracket, so that the emitting surfaces thereof face toward the inner side of a third rail; and the last two laser ranging sensors are respectively installed at the tail end of the installation bracket, so that the emitting surfaces thereof can face the contact surface of the third rail. The device can not be impacted by the specular reflection and has the advantages of high measuring accuracy, small measuring error, continuous measurement and high real-time performance, thereby mainly being used for measuring the height difference and the horizontal distance between the third rail and the waling rail, and providing the scientific assessment management and the planned maintenance of the third rail with the reliable data basis.
Description
Technical field
The utility model relates to a kind of subway parameter detection device, particularly relates to the vehicle-mounted on-line measuring device of a kind of subway the 3rd rail.
Background technology
At present.Subway has dual mode that tractive force is fed on the hauling engine, and a kind of is the way of contact (claiming the 3rd rail again), and another kind is built on stilts contact suspension mode.According to statistical information in 2007, in each big city subway of the world, the 3rd rail mode accounted for 82%.And diff-H between the 3rd rail and rail and horizontal throw can directly influence the stability and the reliability of metro traction car propulsion source.Subway the 3rd rail safeguards that common employing manually holds the method for the 3rd rail track gauge, and not only efficient is low, and work capacity is big, and check point is few in limited power off time, density is low, when breaking away from train operation again dynamically, be unfavorable for the scientific evaluation management and the scheduled maintenance of the 3rd rail." track building " the 5th phase in 1997 has been introduced a kind of " Beijing Metro the 3rd rail height, horizontal throw checking system.Adopting charge coupling device (CCD) is image pick-up device, and the 3rd rail survey sensor promptly is installed respectively in the inspection vehicle both sides, and one-sided detection the 3rd rail height and horizontal throw need 5 sensors and a lighting source.All sensors be installed in the rigidly connected measurement beam of track checking car bogie truck on.The required sensor element of this checking system is more, and also needs lighting source.
Summary of the invention
It is detecting element with the laser range sensor that the purpose of this utility model is to provide a kind of, is not subjected to specular reflections effect, the survey precision height, and measured error is little, and follow-on test, the vehicle-mounted on-line measuring device of subway the 3rd rail that real-time is stronger.
The vehicle-mounted on-line measuring device of the utility model subway the 3rd rail comprises the mounting bracket that is connected on inspection vehicle car body bogie truck and the left and right journal box lid, be installed in 6 laser range sensors on the mounting bracket, wherein two laser range sensors are installed on the midway location of mounting bracket, make its emitting surface towards the rail medial surface, be used to examine the distance between side two rails; Two other laser range sensor is installed in the mounting bracket two ends respectively, and its emitting surface is used to detect the horizontal throw between the 3rd rail medial surface and the laser range sensor towards the 3rd rail medial surface; Latter two laser range sensor is installed in the mounting bracket end respectively, and its emitting surface is used to detect the vertical distance between the 3rd rail contact surface and the laser range sensor towards the 3rd rail contact surface (the 3rd rail upper surface or bottom surface).
The principle of work of the vehicle-mounted on-line measuring device of the utility model subway the 3rd rail is, subway the 3rd rail is installed in the circuit both sides, in the inspection vehicle operational process, two laser range sensors that are installed on the mounting bracket midway location are measured two rail inboards respectively, obtain two rail gauges, and the size by two laser range sensor observed readings, calculate the mounting bracket center-point because the inspection vehicle wheel is made the horizontal direction side-play amount that serpentine locomotion produces along rail, thereby find the gauge reference target on the 3rd rail horizontal surface direction; Aspect in addition, because mounting bracket is fastened on the inspection vehicle, and wheel contacts all the time with rail during operation, so mounting bracket and rail rail level position are constant, thereby has determined gauge reference target on the 3rd rail vertical direction; Two laser range sensors that are installed in the mounting bracket two ends are measured the 3rd rail medial surface respectively, because the 3rd rail medial surface is non-linear cambered surface, there is variation in the vertical dimension of the 3rd rail within the specific limits because of construction reason in addition, therefore, need to carry out the horizontal-shift value and demarcate, be offset calibration value according to observed reading and horizontal direction and determine horizontal throw between the 3rd rail medial surface center and the laser range sensor some points on the 3rd rail medial surface vertical direction; Two laser range sensors that are installed on the mounting bracket end are measured the 3rd rail contact surface respectively, obtain the vertical distance between the 3rd rail contact surface and the laser range sensor.At last, going out with the rail according to above-mentioned result of a measurement reduction is the 3rd rail of benchmark and horizontal throw and the vertical distance between the rail again.
The advantage of the vehicle-mounted on-line measuring device of the utility model subway the 3rd rail is, on the one hand owing to adopted the laser range sensor of Li-CCD triangle imaging measurement principle, thereby is not subjected to mirror to become the influence of reflection, guarantees that survey precision reaches 0.1mm.The aspect laser range sensor adopts integrated mounting bracket in addition, and guarantee the constant distance between each sensor, thereby reduced measured error greatly, for ± 1mm.Moreover this installs continuous gauging, and is real-time.Be mainly used in difference of height and the horizontal throw measured between the 3rd rail and the rail, for the management of the 3rd rail scientific evaluation and scheduled maintenance provide the authentic data foundation.
