Abstract
The utility model relates to a vehicle number of axles recognition device, including the sensor, its characterized in that sensor settings is on the upper surface of base, the base is connected on the ora terminalis of truck scale balance body vehicle walking direction. It is preferred the sensor can be for rectangular platelike structure, be equipped with the recess that link up along sensor length direction on the lower surface of sensor, the sensor is through a plurality of screw connections the base. Compared with the prior art, the utility model provides a vehicle number of axles recognition device passes through the base direct mount on the end of the truck scale balance body with the sensor, does not need other structures as the carrier of transmission, and mechanical parts is few, simple structure, and the signal response frequency is high, and it is good to detect the precision, and with low costs, and the fault rate is low, long service life.
Description
Technical field
The utility model relates to metering outfit, specifically refers to a kind of vehicle number of axle recognition device.
Background technology
In highway overrun testing method, complete-vehicle-type is weighed because its weighing precision is high and is extensively employed.In current car load weighing system, traditional vehicle number of axle recognition methods needs to arrange recognition device separately, and this recognition device and truck scale are installed separately; need to do separately mixed earth basis; installation and maintenance difficulty is large, and cost is higher, often there will be erroneous judgement in use procedure.
Publication number is that the Chinese utility model patent of CN202562593U discloses one " complete-vehicle-type meter weighs and number of axle recognition device ", it comprises electronic vehicle weighing apparatus, described electronic automobile weighing apparatus is provided with number of axle identification weighing platform, described number of axle identification weighing platform comprises panel, brace summer, base for supporting and sensor assembly, and brace summer is connected with electronic automobile weighing apparatus termination with base for supporting; Number of axle identification weighing platform is installed on electronic vehicle weighing apparatus on the surface of termination.Number of axle recognition device and electronic vehicle weighing apparatus are designed to one by this utility model patent, avoid the trouble into the independent casting concrete basis of number of axle recognition device.But this number of axle recognition device is arranged between sensor and stiff end by axle sensor pressing plate, axle sensor pressing plate adopts two hook bolts to connect, and the centre position of whole length direction can not be used for fixing structural member; In use, under the effect that tire is long-term, easily there is flexural deformation in axle sensor pressing plate, and the bolt at two also can lose efficacy under long-term Moment, causes structural member and truck scale body to depart from, cause security incident; This structure wheel axis signal is delivered on sensor by axle sensor pressing plate is stressed in addition, the actual use response frequency of sensor can be caused like this to reduce, easily cause erroneous judgement.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of long service life, signal response frequency high and the vehicle number of axle recognition device that accuracy of detection is good for the present situation of prior art.
The utility model solves the problems of the technologies described above adopted technical scheme: this vehicle number of axle recognition device, comprise sensor, it is characterized in that described sensor setting is on the upper surface of base, described base is connected on the ora terminalis in truck scale body vehicle to run direction.
Described sensor can be long strip-board shape structure, and the lower surface of described sensor is provided with through groove along sensor length direction; Described sensor connects described base by multiple screw.This structure can effectively prevent sensor and truck scale body from departing from, thus extends the serviceable life of this recognition device, and can ensure accuracy of detection.
As improvement, described sensor can have two, is docking together along its length.Because the spacing between automobile two-wheeled is comparatively large, only with a sensor, the length of sensor can be very long, and difficulty of processing is large, and processing cost is high.This programme adopts two sensor splicings, greatly reduces difficulty of processing and the processing cost of sensor.
Described base comprises the substrate be connected with truck scale body, and described substrate supporting is in polylith back up pad; Each described back up pad interval is arranged.Back up pad plays the effect of reinforcement, substantially increases the intensity of base, effectively prevent the irreversible transformation of substrate, further ensures accuracy of detection.The connected mode preferred weld of substrate and truck scale body, can certainly select other connected mode as required.
Preferably, described sensor can be mutually concordant with the height of truck scale body.
Compared with prior art, sensor is directly installed on the termination of truck scale body by base by vehicle number of axle recognition device provided by the utility model, do not need other structural members as the carrier transmitted, mechanical part is few, and structure is simple, and signal response frequency is high, accuracy of detection is good, and cost is low, failure rate is low, long service life; Adopt two sensor splicings to use in preferred version, reduce further difficulty of processing and the processing cost of sensor.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the utility model embodiment decomposition texture.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, this vehicle number of axle recognition device comprises:
Sensor 1, is long strip-board shape structure, has two, dock along its length, and the lower surface of each sensor 1 is provided with through groove 11 along sensor length direction, if width requirement is not high, also can be designed as a king-size sensor 1; Described sensor 1 is arranged on the upper surface of substrate 21 by multiple screw 3.Sensor 1 can select as required of the prior art any one, such as current sensor, voltage sensor, etc.
Base 2 is the mounting seat of sensor, comprises the substrate 21 welded together with truck scale body 4, and substrate 21 is bearing in polylith back up pad 22; Each back up pad 22 is riser, and the length direction interval along substrate is arranged.Substrate 21 is welded on the front-end edge in truck scale body 4 vehicle to run direction.
After this vehicle number of axle recognition device installs, the upper surface of sensor 1 is concordant with the upper surface of truck scale body 4.
The principle of work of this vehicle number of axle recognition device is described below:
When vehicle enters, when vehicle front-wheel is through sensor, sensor exports first time data; When second pair of wheel is through sensor, export second time data, when the 3rd pair of wheel is through sensor, export third time data; Until last pair of wheels, export last data.The number of times of sensor output data is the number of axle of automobile.
