It is axle identification sensor under four angles in face, is cylindric spacing bullet under the through hole of two diagonal point of intersection of axle evaluator table top
Spring;The cylindrical shape that axle identifier station face pressure is arranged under the through hole of axle identification sensor and axle identifier station face diagonal point of intersection
In limit spring, corresponding through hole and cylindric limiting buffer spring of the axle evaluator table top caging bolt through axle evaluator table top
Cylinder, be screwed on step in corresponding screw socket;Swivel bolt adjustment axis evaluator table top level height, it is ensured that axle identifier station
Face and four axle identification sensor Mechanical Contact on step;Pad, adjustment axis evaluator table top is added and subtracted under axle identification sensor
Height is straight with overall scale weighing platform table top.
The dynamic entirety scale weighing platform of the embedded axle evaluator in described front and back end, is characterized in that, by symmetrical principle, whole
The right side on edge on the front and back end of body scale weighing platform, arranges downward local rectangular step, the installation axle evaluator on the step.
The operation principle summary of the dynamic entirety scale weighing platform of the embedded axle evaluator in this utility model front and back end:Front and back end is embedded in
The two layer transducer structure of the dynamic entirety scale weighing platform of axle evaluator, it is ensured that the weighing platform of the structure, at the same obtain axle weight and
Gross weight.Vehicle is sailed and, and first wheel is pressed onto overall scale weighing platform and axle evaluator front end, and overall scale obtains first axle weight, axle
Evaluator obtains first axis information;First wheel is pressed onto axle evaluator rear end after a while, and axle evaluator obtains vehicle movement side
To information;Subsequent second wheel entirety scale and axle evaluator, overall scale obtain the gross weight of two axles, and axle evaluator obtains second
Individual axis information and direction of vehicle movement information;After again, overall scale obtains the gross weight of three axles, and axle evaluator obtains the 3rd axle letter
Breath and direction of vehicle movement information;----;Last entirety scale obtains gross combination weight, and axle evaluator obtains whole axis informations and vehicle
Direction of motion information;Host computer judges the type of vehicle according to axis information, by always reassigning each axle axle weight.If due to certain original
Cause, loses number of axle information, and vehicle drives off, and the axle evaluator of overall scale weighing platform rear end can measure number of axle information again, judge vehicle.
Due to measuring the number of axle twice, the number of axle can be judged with redundancy approach, improve the accuracy of measurement, improve the efficiency of measurement weight calculation.
The usefulness of the dynamic entirety scale weighing platform of the embedded axle evaluator in this utility model front and back end is individually to apply
Work does the basis of Wheel axle identifier, does not damage the longitudinal girder structure of existing overall scale weighing platform, easy to process, compact conformation;By
In the axle evaluator table top caging bolt structure of axle evaluator table top, axle evaluator table top is difficult to topple;Its usefulness also has,
Construction is simple, reliable operation, and it is convenient to keep in repair.

Specific embodiment
The dynamic entirety scale of the embedded axle evaluator in GQTd12-150t front and back ends produced with * * * * high-techs limited company
Weighing platform is specific embodiment, is described as follows:On the upper edge (wheel first press for front) of the front-end and back-end of overall scale weighing platform, keep left
Side, welds the local step of a downward 300*1800*200 millimeter with steel plate.The overall width of overall scale weighing platform is 2600 millis
Rice, on the left of front end, the width of step only has 1800 millimeters, and step does not traverse weighing platform, simply the local step of side.Overall scale
Longitudinal girder construction of weighing platform is constant, and horizontal girder construction shortens, and cuts a platform in the left side of front and back end, welds on platform lower
The steel plate (300*1800) of tape splicing reinforcement, used as step.The corner of step withBitangent is justified, and arranges axle evaluator sensing
Device base;In the diagonal intersection point of step, arrangeScrew socket.Axle evaluator mesa dimensions:Four side of 300*1800 steel plate strips adds
Strong muscle, arranges the bolt hole of countersunk bolt in the diagonal intersection point of axle evaluator table top.Install, the corner of step with
Axle evaluator sensor is set at bitangent circle, with pad adjustment axis evaluator sensor height, axle evaluator table top machinery is made
After four axle evaluator sensors of contact, table top is substantially flush with integral scale table face.Fixing axle evaluator sensor after adjustment
Base.Cylindric limiting buffer spring is set in step diagonal intersection point, axle evaluator table top caging bolt passes through axle evaluator
The cylinder of the corresponding through hole of table top and cylindric limiting buffer spring, is screwed into corresponding in before and after's stepIn screw socket.Adjust
The height of axle identification sensor, tightens bolt, makes axle evaluator table-surface level, and straight with overall scale weighing platform table top.Axle is recognized
Four axle identification sensor outputs under the corner of device table top are consistent, are close to null value or bigger.So, the embedded axle in rear and front end is known
The overall scale weighing platform of other device is manufactured successfully.As the sensor series of left and right two under axle evaluator table top are one group.By in front and back
The time difference of two groups of axle identification sensor outputs, can differentiate the direction of motion of vehicle.Under overall scale weighing platform, same setting is weighed
Sensor.Due to the weight going down of axle evaluator, overall scale obtains axle weight information simultaneously.
According to left-right symmetric relation, the right side on edge on the front and back end of overall scale weighing platform, same method arrange downward rectangle
Step and the corresponding axle evaluator of installation, and the same technical scheme of this utility model protection.
Recent application it was verified that the dynamic entirety scale weighing platform of the embedded axle evaluator in this utility model front and back end it is beneficial it
Place is individually need not to construct to do the basis of Wheel axle identifier, does not damage the longitudinal girder structure of existing overall scale weighing platform, processing
It is convenient, compact conformation;Due to the axle evaluator table top caging bolt structure of axle evaluator table top, axle evaluator table top is difficult to incline
Cover;Usefulness also has, and construction is simple, reliable operation, can be counted weight with redundancy or not parking weight calculation, and it is convenient to keep in repair.
