Abstract
Disclosed is a measurement criterion automobile for calibration and failure discrimination of a motor truck scale and the measurement criterion automobile belongs to the field of calibration of the motor truck scale. The measurement criterion automobile includes a tractor and a trailer and is characterized in that a hydraulic lifting tractive saddle is arranged between the tractor and the trailer; the hydraulic lifting tractive saddle is arranged on the tractor; the bottom part of the trailer is provided with four pneumatic support legs; counterweights are arranged in the internal part of the trailer; the front pneumatic support legs bear 60% of the counterweights; and the rear tyres and the rear support legs bear 40% of the counterweights. The measurement criterion automobile for the calibration and failure discrimination of the motor truck scale reduces labor intensity of calibration personnel, improves working efficiency and speeds up calibration schedule so that personnel security is protected. So in motor truck scale maintenance and failure discrimination, handling time is reduced and working efficiency is improved because of the rapidness and convenience of the measurement criterion automobile.
Description
Technical field
The utility model belongs to the calibrating field of truck scale, is mainly used in the unbalance loading test of truck scale, has to relate to a kind of measurement standard car for truck scale calibration and fault distinguishing.The present invention be applicable between the truck scale of different size comparison and use in check; The fault that is applicable to the LOAD CELLS of weighing apparatus such as truck scale is judged; Be used for the unbalance loading test of truck scale.
Background technology
The calibrating of a truck scale all will be removed a large amount of 1t counterweights according to 75% of full scale, and many table tops weighing apparatus can not satisfy the requirement that unbalance loading is tested greatly at single table top counterweight heap area, and not only workload is big, inefficiency, there is potential safety hazard in the use, and takies a large amount of liftings, haulage vehicle.For because weighing apparatus which only or the reduction of which sensor performance index, the fault of the weighing apparatus error that causes is judged does not have good determination methods yet.The judgement poor for the section of many table tops weighing apparatus can only rely on the haulage vehicle of other unit to operate at a weighing apparatus, the comparison vehicle weight often can't satisfy the comparison condition, driver's match ratio of also being unwilling is right, can not unify to analyze and judge to the overall operation situation of the truck scale of full company when analyzing weighing apparatus and using state.
Summary of the invention
In order to judge the fault of the LOAD CELLS of weighing apparatus fast, it is a kind of for the measurement standard car of truck scale calibration with fault distinguishing that the utility model provides.
The utility model comprises tractor, trailer railway carriage or compartment, it is characterized in that being provided with between tractor and the trailer railway carriage or compartment hydraulic lifting traction saddle, hydraulic lifting traction saddle is arranged on the tractor, and the bottom in trailer railway carriage or compartment arranges four pneumatic supporting legs, and the counterweight counterweight is set in the compartment in trailer railway carriage or compartment.
Anterior pneumatic supporting leg is born 60% counterweight counterweight, and rear portion tire and rear portion supporting leg are born 40% counterweight counterweight.
Described hydraulic lifting traction saddle is made up of hydraulic cylinder, oil pump and traction saddle, and hydraulic cylinder connects oil pump and traction saddle respectively.
Oil cylinder was realized connecting fast at low level when tractor was connected with the trailer railway carriage or compartment.When trailer railway carriage or compartment and tractor disintegrated, hydraulic cylinder lifting saddle, pneumatic supporting leg turned to vertical working position.The hydraulic cylinder landing realizes that pneumatic supporting leg supports the trailer railway carriage or compartment, and tractor and trailer railway carriage or compartment vertical direction break away from.Tractor is left, and the trailer railway carriage or compartment is placed on the position of parking ground or the sensor correspondence of weighing apparatus, and the fault that is used for the weighing apparatus error is judged or the test of weighing apparatus and the comparison between weighing apparatus in interval.
Described pneumatic supporting leg is made up of cylinder, supporting leg and safe register pin.Cylinder, supporting leg are hinged with the trailer railway carriage or compartment respectively; The end and the trailer railway carriage or compartment that are cylinder are hinged, and the other end and the supporting leg of cylinder are hinged, and supporting leg first end is hinged on the envelope of trailer railway carriage or compartment.
Safe register pin automatic in-position prevents from toppling over before and after the supporting leg when pneumatic supporting leg turns to vertical working position.Safe register pin ejects when mobile trailer railway carriage or compartment, and pneumatic supporting leg rotates the stowed position; The trailer railway carriage or compartment can be moved.
During work, fall the pneumatic supporting leg of anterior 40T level (must with the supporting use of tractor of band lifting saddle), supporting leg and vehicle bridge place can obtain even load (by the balancing weight encapsulation acquisition that mixes up); When parking when long, fall the rear portion supporting leg that manually links again, can prolong each load bearing component serviceable life.
Requirement according to the national verification rules is built mark to measurement standard car car load.A calibration accuracy is arrived 50 tons truck scale of 2/3 franchise, build mark weighing apparatus as measurement standard car car load.
The utility model arrives operation field, and the rise of hydraulic lifting traction seat puts, wears pneumatic front leg strut upset in place pin and fixes, and tractor is left after taking off extension.The utility model is as the movable modular substitute, calibration weighing apparatus, and fast convenient, operation expense is low, and trailer railway carriage or compartment and tractor are deciliter quick.
The utility model has alleviated testing person's labour intensity, has improved work efficiency, has accelerated the calibrating progress; Protect people's safety and efficient and convenient, improved weighing apparatus maintenance, testing person's fault judgment processing time and work efficiency greatly.
