Description
Technical field
The utility model relates to uses the device, particularly track meausring apparatus that character that resistance changes with amount of force is come metering power or stress.
Background technology
Constantly rail track weighing device is compared with disconnected rail type track weighing device, and it is low to have cost, short construction period, characteristics such as stability in use, reliability and high safety.The existing main rail cushion of continuous rail track weighing device sensor, filling type sensor and clamping touch sensor, filling type sensor and clamping touch sensor can be described as shear strain formula sensor.Rail cushion sensor is that the form with sleeper replaces regular sleeper between two regular sleepers of the alternate distance of track section, be encased inside below the rail, its quantity is decided according to the actual requirements, as many as is several, tens, few to one, two, when wheel from the rail through out-of-date, its weight directly affacts on the sensor by rail, realizes Weighing.This device is owing to exist the zone of transition of weighing-non-weighing to influence weighing precision at the Weighing Area two ends.Shear strain formula sensor is installed on (the filling type sensor is installed on the mounting hole that web is reserved) near the rail web central core, when wheel from the rail through out-of-date, rail is subjected to heavily to produce deformation, its Stress Transfer realizes Weighing to sensor.The major defect of this device is that the weighing zone is short, thereby influences weighing precision.
Rail cushion sensor and shear strain formula sensor groups are lumped together, constitute the continuous rail track of combined type weighing device, can overcome both and use the low problem of lacking of institute's weighing precision that produces separately with the weighing district.What the previous CN2398620Y of the inventor announced is exactly this weighing device.
It is several that the track meausring apparatus is divided into wheel shaft metering, bogie metering and car load metering by the integral body of Weighing body and local metering.Adjacent forward and backward two axles constitutes bogie, constitutes car load with forward and backward two bogies of car.So adjacent forward and backward two axles metering can be combined into the bogie metering when weighing is handled, be combined into the car load metering with the forward and backward two bogies metering of car.But the common error of result that is combined into whole metering by part metering is bigger, otherwise it is also big that the integral body metering is split as local metering resultant error.The present track meausring apparatus of using, its weighing mode (weighing function) all is single, i.e. and the heavy and bogie of wheel shaft that can not detect of car load metering weighs, and vice versa.
Summary of the invention
It is single at wheel shaft metering, bogie metering or car load metering upper type that the utility model will solve the current track meausring apparatus, can not one equipment simultaneously or have both multiple metering method, cause big, the problems such as metrological operation is complicated, equipment cost height of error in dipping, the continuous rail track of a kind of multifunction combined no foundation ditch of the present utility model meausring apparatus is provided for this reason, this track meausring apparatus has wheel shaft weighing, bogie weighing and car load weighing function concurrently, metrological operation is convenient, the metering resultant error is little, and equipment investment cost is low.
For addressing the above problem, the technical solution adopted in the utility model is to be provided with rail cushion sensor, its special character is that pad is provided with some described rail cushion sensors below the rail section between alternate two sleepers of track, rail web between each sleeper of two sleepers rail cushion sensor adjacent with this sleeper is provided with shear strain formula sensor, also is provided with shear strain formula sensor on the rail web between the two described rail cushion sensors.
The formula of shear strain described in the utility model sensor can be the filling type sensor, also can be to clamp touch sensor.
Described filling type sensor is known.No. 201020256600.1 utility model patent instructionss of the ZL that described clamping touch sensor is the applicant are disclosed.
Some rail cushion sensors described in the utility model can be directly installed on all kinds of shaped steel plane, the pre-buried steel backing plate of concrete ground beam, the steel framework platform (rigid frame scale body) by mounting seat, again the whole piece rail is fixed on the rail cushion sensor by Ministry of Railways's standard method, spreads the vibration damping rubber cushion for what reduce that vibration can be at the rail cushion sensor and the rail flange of rail.Some rail cushion sensors form a weighing-up wave induction zone.When external force (wheel wheel load) affacts on each sensor by rail, form the stressed weighing-rail of many fulcrums, sensor just produces an output signal that is directly proportional with external force.Can increase and decrease the quantity of rail cushion sensor easily according to actual needs, to prolong or to shorten effective weighing district.
Rail web between each sleeper of the utility model two sleepers rail cushion sensor adjacent with this sleeper is provided with shear strain formula sensor, be respectively to be provided with shear strain formula sensor on the rail web between whole rail cushions sections of sensors two ends and the sleeper, shear strain formula sensor can be the filling type sensor, also can be to clamp touch sensor, it is installed near the rail web central core, play the effect of compensation rail cushion sensor signal, also play the effect of isolating external force simultaneously.
Respectively be provided with the shear strain formula sensor on the rail web of the utility model between whole rail cushions sections of sensors two ends and sleeper, on the rail web between the two described rail cushion sensors, also be provided with shear strain formula sensor, promptly call the turn between the two rail cushion sensors of a desired area and also be provided with shear strain formula sensor on the rail web with respect to the end, the effect of its same compensation rail cushion sensor signal, just the position in weighing district is different with length.
The utility model since below the rail section between alternate two sleepers of track pad be provided with some rail cushion sensors, rail web between each sleeper of two sleepers rail cushion sensor adjacent with this sleeper is provided with shear strain formula sensor, rail web between the two described rail cushion sensors is provided with shear strain formula sensor, so on the basis that can remedy single rail cushion sensor or single shear strain formula sensor signal errors, can also overcome defective whole and local weighing function singleness, be that the utility model is with the car load weighing, the function of bogie weighing and wheel shaft weighing, accomplish that weighing is convenient, accurate measurement, equipment cost is low on the whole.
