Description
Technical field
The present invention relates to a kind of detecting device of railway track parameter, be adapted at detecting on the various rails and use.
Background technology
At present, the measurement of railway track parameter, mostly adopt the manual machinery mode to carry out, the width of railway track and parallelism kind of calliper, though equipment is simple, but its deficiency is the effort of taking a lot of work, survey precision is low, be difficult to reach technical requirements, because train speed-raising at present is strict more to the requirement of rail, measurement and maintenance to rail are just more important, in case rail occurs than large deviation, technical error will appear in the locomotive of high-speed cruising, no matter can cause very big loss economically with in the personal safety.
Summary of the invention
For solving the measurement of rail parameter, the invention provides a kind of electronic track gauge, utilize the accurate measurement of mechanical drive and electronic circuit two parts realization to the rail parameter.
Technical solution of the present invention is achieved in that electronic track gauge forms (as shown in Figure 2) by mechanical driving part and control circuit two parts, be an oblong bearing in the middle of the mechanical driving part wherein, at the bearing center horizon sensor is housed, track gauge sensor, control circuit board is housed simultaneously, the fixing combination hub in signal wire (SW) and side joins, the gauge support wheel is equipped with at the bearing two ends respectively, support wheel is fixed on the horizontal stand, with the bearing center is symmetrical structure, bar is equipped with in the horizontal stand both sides, return spring is equipped with in the inside, wherein inboard two ends bar all joins with track gauge sensor, two parallel walking wheels are equipped with perpendicular to support in the outside of support, it below the walking wheel tested rail, wherein a walking wheel termination connects with the odometer sensor of fixing, and is fixed with handspike in the outside, bearing center, and source switch is equipped with in the handspike termination; Control circuit is made up of central process unit and auxiliary circuit, the input end of central controller connects with track gauge sensor, horizon sensor respectively, odometer sensor passes through to connect with another input end of controller behind comparator, the conv, controller output end joins by IC serial port and PC, central controller is connected to memory, central controller joins by cable and hand-held design keyboard, read-out, central controller is installed on the circuit card at bearing center, connects with hand-held design keyboard read-out by combination hub.
Advantage of the present invention: simple in structure, reasonable in design, easy to install, because of sampling, calculate with electronic circuit, the survey precision height is used extensively, and working stability is reliable.
