Description
Technical field
The utility model relates to a kind of automobile load weighing device, and particularly fixing with mobile dual-purpose load data is handled weighing device.
Background technology
Automobile overload is one of reason of taking place of many traffic hazards, also is one of vehicle supervision department's persistent ailment of always putting forth effort the violation traffic control rules administered.Differentiate and whether overload, at first will measure the automobile real load.The automobile load weighing device has a variety of at present, such as truck scale, and the application time is longer, adopts also more.But because its volume is bigger, special installation be arranged, use the place, generally be fit to the little occasion of vehicle flowrate, use is set as enterprises; Electronic scales for example again, type is many, be to utilize the distortion of matrix under the automobile loading, displacement etc. mostly, carry out signal sampling by sensor, carry out data processing again and obtain the automobile load data, exist in the use error big, influenced greatly by the speed of a motor vehicle, the life-span is lower, the more high deficiency of maintenance cost.Also some price is higher, not too is fit to large tracts of land and adopts.Because automobile is the equipment that flows, flow range spreads all over the world with network of highways, set up automobile overload monitoring and improvement network comprehensive, normality, need error little, life-span is long, price is low, the automobile load weighing device of easy care, and should be easy for installation, preferably can also move to any occasion as required and use, can carry out highway with machine testing.
Utilize the hydraulic technique for the treatment of as incompressibility of liquid to be widely used in the commercial production, for example hydraulic cylinder, hydraulic jack or the like, the relational expression below their power output F, working chamber area A, fluid pressure p satisfy:
F＝A·p
Formula is rewritten, is become and do:
p＝F/A
This shows that after having determined the working chamber area, the loading force that cavity pressure bears with it is linear, that is to say, fully can be by the measurement of gaging pressure p realization to loading force F.Pressure transducer with state-of-the art production is a load cell, and its precision should satisfy technology and the life requirements that measured automobiles load is weighed with stability.
The purpose of this utility model is to provide a kind of fixing, mobile dual-purpose automobile load weighing device, thereby a kind of load of measured automobiles sustainedly and stably is provided, and can fix the new method of monitoring and administering automobile overload in combination with flow detection.
Summary of the invention
The technical scheme that the utility model automobile load weighing device is adopted is: design a liquid cavity, the cavity bottom design has platform, is processed with the connecting hole that can pass foot bolt on the seat board.Design has a sensor mounting hole on the cavity, in sensor and the chamber mutually the earthing be connected on the cavity.Design has piston in the cavity, and piston cooperates installation with cavity inner wall, and is equipped with O-ring seal, and liquid is encapsulated in the cavity.Be fixed with pin on the piston, pin hole greater than the pin diameter from the cavity wall passes.The piston upper end links to each other with bearing plate.The sensor output line links to each other with digital treating meter.The fixed installation of automobile load weighing device can have two kinds of installation forms when using, a kind of is that heavy hole formula is installed: build two heavy holes by automobile wheel track on passage, two the utility model automobile load weighing devices are installed in the heavy hole with foot bolt, and make the common axis of cavity and piston sail 1 °～20 ° angles of direction inclination, and guarantee that bearing plate exceeds the road surface to automobile.When the speed of a motor vehicle was very fast, wheel can produce a small amount of the impact to fluid chamber by bearing plate, the sluggish error of liquid cavity internal pressure rising when passing through fast with balance.When wheel was pressed on the bearing plate fully, hydraulic pressure rose in the liquid cavity, and after vehicle passed through, sensor recorded the pressure rising value that automobile front axle gravity and rear axle gravity causes respectively and is transferred to digital treating meter, can show after data processing, print.Another kind is that install on the road surface: two the utility model automobile load weighing devices are directly installed on the road surface with foot bolt, make the common axis of cavity and piston sail 1 °～20 ° angles of direction inclination to automobile, this moment, bearing plate was designed to arc surfaced, the face of cylinder is processed in the piston upper end, bearing plate is connected by the bearing pin contact with piston, bearing plate can be swung for supporting " seesaw " formula of work the piston upper end, when automobile passes through, wheel is pressed to bearing plate earlier, the one-sided contact seat board of bearing plate, when wheel pressed the bearing plate top fully, the bearing plate two ends were unsettled, and sensor records true gravity.When the automobile load weighing device need move use, two road surface installing type the utility model automobile load weighing devices can be placed on the road surface of automobile two-wheeled process, make the common axis of cavity and piston sail 1 °～20 ° angles of direction inclination to automobile, automobile on the platform sails a side that web joint is installed, web joint is guaranteed when automobile passes through in the length of automobile working direction, wheel is pushed down web joint earlier, presses bearing plate then, and is identical when the course of work fixedly mounts with the road surface thereafter.
Compare with the automobile load weighing device of present employing, the utility model provides a kind of cost not high, and installation and maintenance are simple, again the automobile load weighing device that can conveniently move, and a kind of energy reliable measurements is provided, be subjected to matrix, the speed of a motor vehicle to influence little automobile load measuring method.
