Description

Electronic track gauge

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.

The specific embodiment

The detection ruler physical construction as shown in Figure 2,1 is bearing, 2 is the control circuit connection plug, 3 are the circuit battery, 4 be a siding track apart from support wheel, 9 is opposite side gauge support wheel, both sides are symmetrical structure, 5 is odometer sensor, and 6 is walking wheel, and odometer sensor is fixed on the walking wheel termination, utilize inner code-disc record travel distance, gauge support wheel and walking wheel are fixed on support 14, on 15, be placed on just on the rail, be with spring on the bar of inner end, two bar medial ends are connected with track gauge sensor 11 two ends moving elements respectively, because rail not parallel, but gauge support wheel left and right horizontal a little move, 7 is control circuit board, be fixed in the bearing, 8 is horizon sensor, is fixed on the center of bearing, the fixing handspike 12 that connects with rotating shaft in bearing front, source switch 13 is equipped with in the handspike termination, the bearing other end is equipped with gauge support wheel 9 equally, traveling transmission line 10, whole device is fixing in aggregates, by connection plug and hand-held design keyboard, read-out connects.

Control circuit such as Fig. 4, shown in 5, central controller CPU is AT89C53, odometer sensor, horizon sensor, track gauge sensor all connects with plug, the plug other end connects with the CPU input end, odometer sensor is by voltage comparator LM393, conv AT89C2051 connects with the CPU input end, CPU connects with 2 memories, memory is 24C256, output interface is MAX232, the CPU mouth directly connects with display driver, difference reveal competence length on the read-out, three groups of data of gauge, the input keyboard that the side connects, control circuit has warning function simultaneously.

During use, detection ruler is placed on the railway track advances with the hand propelled detection ruler, three kinds of parameters being surveyed all show by read-out, so that rail is proofreaied and correct at any time.
