Description

The vehicle of vehicle-mounted weighing instrument is housed

The utility model is a kind of vehicle that vehicle-mounted weighing instrument is housed, and adapts to the management of transfiniting of weighing of vehicle-mounted cargo, belongs to general vehicle or electronic scale technical field.

For a long time, the accurate weighing of vehicle-mounted cargo is mainly depended on all kinds of large-scale weighing machines such as truck scale, it costs an arm and a leg, install extremely inconvenient, and can not move, therefore in general have only minority unit just to have, and often just be used for the higher goods of some value is carried out weighing.Along with development and national economy, demand to the vehicle-mounted cargo weighing enlarges day by day, simultaneously because the ubiquity of the development trend of highway transport vehicle heavy-duty and overload phenomenon, vehicle supervision departments at different levels need a kind of low price weighing means efficiently to come the management of transfiniting of all kinds of haulage vehicles too.And LOAD CELLS and Displaying Meter are directly installed on the vehicle, be undoubtedly a best solution.

The research of the vehicle-mounted weighing instrument that carries out in recent years, basically all be to determine goods weight by the vertical deformation amount of measuring spring steel plate, because this distortion itself is non-linear, there is bigger friction force simultaneously between each block plate superposed surfaces, also can bring very big error, so this scheme can not obtain practical application so far.

The at present external relatively vehicle-mounted weighing instrument of popularization and application, mounting means all are that four doube bridge shear beam type sensors are installed in below four angles in compartment basically.This mode relatively is suitable for the tipping bucket type bogie, general fixed compartment then installed be not very convenient, simultaneously because 4 contacts in compartment, destroyed original stress, compartment and vehicle bridge also can produce perturbed force fixedly the time, so this mode effect in actual applications is unsatisfactory, and implementation cost is also higher relatively.

The purpose of this utility model is at the deficiencies in the prior art, and a kind of vehicle that vehicle-mounted weighing instrument is housed is provided, weighing instrument direct convenience ground dress onboard, accurately weighing, and operation is simple and reliable, adaptation is to the management of transfiniting of weighing of various vehicles.

For realizing such purpose, the utility model adopts the vehicle-mounted force cell of ultrathin high precision of four particular design, be installed in respectively between the crossbeam of vehicle spring steel plate and vehicle bridge, can directly and exactly export and vehicle-mounted corresponding four road weight signals, be sent to the Displaying Meter that is installed in the pilothouse by shielded cable.

Sensor is the radial pressure transducer, comprises outer shroud, interior ring and spoke, and its outer shroud is slightly protruding upward, fixes by last location-plate and vehicle steel plate, and interior ring protrudes slightly downwards, fixes by register pin and vehicle bridge.Spoke between the inner and outer ring has eight circular holes, forms eight spokes, and wherein four spokes post the responsive load of foil gauge, and four are auxiliary spoke.

Instrument adopts the four-way design, can carry out weight separately to each road signal and demarcate and measure, thereby make the system accuracy can be near the performance index of truck scale.Instrument not only can demonstrate the general assembly (TW) (or gross weight of automobile) of automobile institute cargo, and can also show the heavy and wheel load of axle, is convenient to the overload and the unbalance loading situation of driver, traffic police or other personnel inspection vehicle.In addition, instrument also can have the setting and the functions such as warning, data-storing and printing, real-time clock calendar of load or unload amount.

Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model force cell installation position.

Among the figure, the pressing plate 1 of automobile spring plate compresses automobile spring plate 2, last location-plate 3 with the outer shroud of ultrathin force cell 4; Backing plate 5 on the vehicle bridge is fastening with the interior ring of sensor 4 by register pin 11, makes between sensor 4 and the vehicle bridge crossbeam 10 and can not produce relative displacement; The ＂ of automobile spring plate rides ＂ screw 6 by clamp sleeve 7, last location-plate 3, following location-plate 8 and nut 9, and sensor 4 and vehicle bridge backing plate 5, steel spring plate 2 closely are fixed together.Compartment and pay load are delivered to sensor 4 by steel spring plate 2 through last location-plate 3 like this, and location-plate 8 is delivered to vehicle bridge under the warp again, is delivered to the road surface by wheel at last, thereby make sensor direct sensitivity go out railway carriage and pay load.

Fig. 2 is the structural representation of facing of vehicle-mounted force cell in the utility model.

As shown in the figure, vehicle-mounted force cell is a spoke structure, and the outer shroud 12 of sensor is slightly protruding upward, and interior ring 14 protrudes slightly downwards, between interior ring 14 and the outer shroud 12 spoke 13 is arranged.

Fig. 3 is the plan structure synoptic diagram of onboard sensor in the utility model.

As seen, between the outer shroud 12 of sensor and the interior ring 14 spoke 13 is arranged among the figure, spoke 13 has eight circular holes and forms eight spokes.

In embodiment of the present utility model, sensor outer shroud 2mm protruding upward fixes by last location-plate and vehicle steel plate, and interior hoop protrudes 2mm down, fixes by register pin and vehicle bridge.Like this, the overall height of sensor does not influence original performance of vehicle basically below 20mm, and the center of gravity that can not make vehicle raises and influence the security of vehicle transport on the way.

Because the spoke structure of sensor particular design, make the only responsive shearing force of sensor, promptly parallel power with sensor axis, so sensor has good susceptibility to the loading force perpendicular to ground, and have the very strong inhibition side force and an ability of horizontal impact, mix the hyperchannel design of instrument, can more effectively overcome the error that sensor characteristic is inconsistent and unbalance loading is brought, therefore can reach higher measuring accuracy.Test shows, when automobile was parked on the smooth-riding surface, weighing system can reach the precision of simple automobile weighing apparatus, when automobile when advancing, to different vehicles, the measuring accuracy that reaches is between 0.1%～3%.

The load cell structure advantages of simple of the utility model particular design, needed manufacturing of weighing system and erected cost have only 3%～5% of general-utility car weighing apparatus, except that instrument, sensor and a few parts, all the other all can utilize original parts, both reduced cost, it is also very convenient to install, and does not destroy original structure basically simultaneously, thereby has guaranteed traffic safety to greatest extent.The utility model has realized that " scale " walk with car, and is widely applicable, and simple to operation, and its ratio of performance to price outclass general large-scale weighing machine, applies easily.
