Abstract
The utility model discloses a rubber hose type axle detection sensor of a transport vehicle. The rubber hose type axle detection sensor of the transport vehicle is composed of a closed elastic rubber hose and a pair of photoelectric transmitting and receiving tubes, wherein the rubber hose is provided with a smooth axial hollow cavity type inner wall, and the pair of photoelectric transmitting and receiving tubes comprises a photoelectric transmitting tube and a photoelectric receiving tube which are opposite to each other and are buried in the two ends of the closed rubber hose respectively and are located on the same center line. The rubber hose type axle detection sensor of the transport vehicle is laid on a road surface, when the sensor is pressed by wheels of the motor vehicle, mechanical deformation happens to the rubber hose, corresponding reduced electricity transmitting signals are generated by the photoelectric receiving tube, and acquisition of structural characteristic signals, such as the number of axles and the axle distance, of the vehicle can be achieved. The rubber hose type axle detection sensor of the transport vehicle has the advantages of being small in deformation and high in transmission reliability.
Description
Technical field
The utility model relates to the rubber tube sensor as repacking survey sensing element that pavement of road is set.
Background technology
Existing rubber tubular type sensor is pneumatic inductosyn, requires in the time suffering external force pressure, and rubber tube produces larger mechanically deform, impels electrical contact effectively to respond to action and carries corresponding sensing to become the number of delivering letters.Therefore, use rubber tube checkout gear on the road of heavy traffic, rubber tube is in the frequent alternation of large deformation, and body is easy to damage, and application life is short, so this class detector can only be used in the road occupation occasion that the traffic volume is very low; In addition, realize the output of induced signal by the electrical contact being equipped with, its sensing poor reliability.
Summary of the invention
Goal of the invention of the present utility model be to provide a kind of distortion little, without electrical entity contact, and there is highly sensitive change and send the vehicular traffic rubber tubular type anxis detecting sensor of output.The vehicular traffic rubber tubular type anxis detecting sensor technical scheme that the utility model provides, its main technical content is: a kind of vehicular traffic rubber tubular type anxis detecting sensor, formed by the elastic rubber pipe sealing and a pair of photoemission receiving tube, described rubber tube has smooth axial cavity inwall, described a pair of photoemission receiving tube comprises photoemission cell and photoelectric receiving tube, and two pipes are embedded in relatively, respectively the same midline in blind rubber two ends.
The disclosed vehicular traffic rubber of the utility model tubular type anxis detecting sensor technical scheme, road surface pavement, in the time meeting with vehicle wheels compressing, rubber tube mechanically deform and cause photoelectric receiving tube produce scaled-back electricity become the number of delivering letters, realize the collection of the vehicle architectural feature signals such as axletree number, wheelbase with this, it have distortion little, become and send that reliability is high, simple in structure, the technological merit of long service life.
Accompanying drawing explanation
Fig. 1 is sectional structure chart of the present utility model.
Fig. 2 is use view of the present utility model.
Fig. 3 is that the utility model is in the structure chart that arranges of road.
The specific embodiment
The vehicular traffic rubber tubular type anxis detecting sensor that the utility model provides, is made up of the elastic rubber pipe 1 sealing and a pair of photoemission receiving tube 2,3.As depicted in figs. 1 and 2, described rubber tube 1 every length is to select within the scope of 0～10 meter, photoemission cell 2 is relative with photoelectric receiving tube 3, be embedded in respectively the blind rubber 1 same midline in two ends, the axial cavity of rubber tube 1 has smooth inwall 4, to guarantee that body is in the time having small camber, luminous flux can be not influenced.Rubber tube 1 fixed lateral is laid on pavement of road central authorities, while producing distortion impacted by vehicle wheels mechanical pressure, the part or all of blocking light flux of meeting, the luminous flux that photoelectric receiving tube 3 receives reduces, as shown in Figure 2, and in the time that wheel even load moves, rubber tube distortion recovers, it is normal that luminous flux also recovers thereupon, thereby judge whether that by the change number of delivering letters receiving wheel crosses, and obtain the vehicle architectural features such as the number of axle, wheelbase.
