Abstract
The utility model relates to a kind of axle weighing sensor with overcurrent protection structure; axle weighing sensor adopts " work " word girder construction; the two sides of four stress gauges is posted on respectively " work " word web on the mutually perpendicular position at 45 ° with central axis; it is 15 ~ 20mm that " work " word beam two ends are provided with length, and gap is the overload protection gap of 0.3 ~ 0.5mm.The utility model adopts shearing, and " " structure of word beam, ensure that measuring accuracy to work.Due to it, to have external form low; Lateral force resistance is strong; The features such as structure is simple, main is that this LOAD CELLS has overload protection function, stops like this to cause sensor degradation.The part that axle weighing sensor also can be used as rail can directly be weighed as rail mounted, eliminates weighing platform.Be widely used in the departments such as high speed weight metering charging project, colliery, mine, steel mill at present.Meet overload protection function completely by site test, greatly reduce maintenance cost.
Description
Technical field
The utility model relates to a kind of axle weighing sensor, particularly with the axle weighing sensor of overcurrent protection structure.
Background technology
At present along with the develop rapidly of rapid transit industry, also drive the heavy project of meter at a high speed.The equal No-mistake Principle defencive function of axle weighing sensor in the heavy project of domestic now mostly at a high speed meter, when acting force acts on the two ends of axle weighing sensor respectively, so just makes the other one end that sinks, sensor one end upwards turn over and stick up, is similar to seesaw.Because sensor weighs for wheel shaft for this reason, the travel speed of car added by loaded vehicle on highway, when wheel has just dropped on scale object table face, the impulsive force of moment is sizable, sensor center section will be caused damage that sensor cannot normally be worked if acting force reaches certain limit.Such Long-Time Service will cause the damage of axle weighing sensor, namely fracture is appearred in axle weighing sensor center section, and particularly in frequency of utilization ratio section more frequently, axle weighing sensor degradation is also more frequent.Thus maintenance cost is increased sharply.
Utility model content
The purpose of this utility model is to lower maintenance cost, provides a kind of axle weighing sensor with overcurrent protection structure.
Technical solution of the present utility model is: with the axle weighing sensor of overcurrent protection structure; axle weighing sensor adopts " work " word beam (3) structure; four stress gauges (1) be posted on respectively " work " word beam (3) web two sides and on the mutually perpendicular position at 45 ° with central axis; it is 15 ~ 20mm that " work " word beam (3) two ends are provided with length, and gap is the overload protection gap (2) of 0.3 ~ 0.5mm.
The utility model adopts the structure shearing " work " word beam, and the change of trail force load position based is little on sensor output signal impact, thus ensure that measuring accuracy.Due to it, to have external form low; Lateral force resistance is strong; The features such as structure is simple, main is that this LOAD CELLS has overload protection function, and like this when the application point of power acts on the two ends of sensor, the portable protective gaps at two ends will close, and would not cause sensor degradation.The part that axle weighing sensor also can be used as rail can directly be weighed as rail mounted, eliminates weighing platform.Be widely used in the departments such as high speed weight metering charging project, colliery, mine, steel mill at present.Meet overload protection function completely by site test, greatly reduce maintenance cost.

Fig. 2 is that the B-B of Fig. 1 is to cut-open view.
Fig. 3 is the A direction view of Fig. 2.
Embodiment
With the axle weighing sensor of overcurrent protection structure; axle weighing sensor adopts " work " word beam 3 structure; when axle weighing sensor is arranged on scale body; external force passes to axle weighing sensor by scale object table face; after sensor will sense the effect of power P; the structure measurement of this axle weighing sensor be not normal stress, but measure the shearing stress caused by shearing force.But shearing stress itself can not measured; it can produce the mutually perpendicular principle stress with " work " word beam central axis angle at 45 °; namely produce the drawing stress and compression stress that are caused by shearing stress; therefore in shear beam force cell; four stress gauges 1 be posted on respectively " work " word beam 3 web two sides and on the mutually perpendicular position at 45 ° with central axis; can not damage because of transshipping instantaneously to protect axle weighing sensor; it is 15 ~ 20mm that " work " word beam 3 two ends are provided with length, and gap is the overload protection gap 2 of 0.3 ~ 0.5mm.When the acting force acting on sensor two ends respectively reaches certain value, overload protection gap 2 will close, and will will be integrated up and down like this, acting force P will be delivered to the bottom of sensor.Even if acting force continues to strengthen also by sensor degradation, just can not serve overload protective function like this to sensor.
