Description
Technical field
The utility model belongs to track geometry measuring device, particularly relates to a kind of wheel of track detecting dolly.
Background technology
Track detecting dolly be a kind of detect static track mileage and height, level, distortion, rail to etc. the portable tool of track irregularity parameter.
Existing track detecting dolly is made up of the steel car wheel of little vehicle main body and supporting trolley main body, and wheel engages with non-orbiting scroll.
In order to make little vehicle main body keep stable when moving with wheel, the side of little vehicle main body arranges former and later two larger wheels of wheelbase, and opposite side only arranges a wheel.
The wheel of above-mentioned supporting trolley main body is steel wheel, there is following major defect: between wheel and track, friction drag is little, cause tyre skidding and affect the precision of dolly subject detection data, particularly when raceway surface exists sleet vestige, skidding is particularly serious; Very strict owing to arranging requirement to little vehicle main body and interorbital insulation, therefore, steel wheel will increase the complexity of dolly insulation system.
Summary of the invention
The utility model is the above-mentioned technical matters that exists of steel wheel in order to solve supporting trolley main body and discloses a kind of wheel of track detecting dolly.
The utility model takes following technical scheme for achieving the above object: a kind of wheel of track detecting dolly, feature is, diaxon frame plate corresponding to position is respectively equipped with the synchronous pulley that axle supports in two ends bottom it, two synchronous pulleys are provided with the closed loop tooth form synchronous belt be meshed with it, the rubber outer surface of closed loop tooth form synchronous belt engages with raceway surface, and the top of diaxon frame plate is provided with the top board of supporting trolley main body.
The utility model can also take following technical measures:
The wheel shaft two ends of described synchronous pulley are respectively equipped with the nylon sleeve of interference fit, and described diaxon frame plate is respectively equipped with the bearing supporting synchronous pulley wheel shaft, the nylon sleeve of synchronous pulley wheel shaft and bearing inner ring transition fit.
Described diaxon frame plate is respectively equipped with the axle bed plate supporting mid-ambles belt wheel wheel shaft two ends, the upper portion of the closed loop tooth form synchronous belt between mid-ambles belt wheel with two synchronous pulleys is meshed, the side axle bed plate of described mid-ambles belt wheel is fixed with coder, is provided with coupler between coder axle and mid-ambles belt wheel wheel shaft.
Described diaxon frame plate is symmetrical isosceles trapezoid, position, intermediate portion hollow out.
The feather edge of described diaxon frame plate is interval with the permanent magnet corresponding to track.
The beneficial effects of the utility model and advantage are: this wheel is made up of two synchronous pulleys and closed loop tooth form synchronous belt thereof and pedestal plate, when track detecting dolly is by thrust, this thrust warp beam frame plate is transmitted in two synchronous pulleys and makes it to rotate, closed loop tooth form synchronous belt will rotate with two synchronous pulleys and dolly be advanced, because the rubber outer surface of closed loop tooth form synchronous belt and raceway surface bonding area are far longer than the bonding area of steel wheel and raceway surface in prior art, and the feature of the quality of rubber materials of the outside face of closed loop tooth form synchronous belt causes the friction drag of this gripping wheel larger, therefore the skidding of steel wheel is thoroughly overcome.Also because closed loop tooth form synchronous belt itself has insulating power well, the insulation system of dolly therefore can be simplified.Also because toothed belt transmission has stable, transmitting ratio accurately, therefore, it is possible to ensure that track detecting dolly detects the accuracy of data.Wheel of the present utility model is applied to detection dolly in pairs, the little vehicle main body of fixing its top board when two synchronous pulleys of single wheel have enough large wheelspan will have satisfactory degree of stability, this wheel also can with the large wheelspan steel car in existing dolly side take turns with the use of, large wheelspan steel car wheel is only as making little vehicle main body pulsation-free auxiliary wheel.The utility model have structure simple, be skillfully constructed, the outstanding advantages of superior performance.
