Abstract
The utility model relates to a dynamic-static dual-purpose automatic railroad track scale, which is formed by the method that a weighing sensor is arranged on the bottom part of a weighing platform and weighing steel rails are arranged on the weighing platform. At least one group of car axle recognition sensors is arranged on the weighing platform, each group of the car axle recognition sensors is composed of an infrared switch, an induction type proximity switch, a pressure sensor and one kind of shearing force sensors, signals collected by the weighing sensor and the car axle recognition sensor are simultaneously input in an external connection computer processing system, and dynamic-static weighing measurement and display for vehicles can be realized. The utility model has the advantages of simple structure, rapid and accurate weighing, stable and reliable operation, convenient operation effect and simple installation and maintenance, and the utility model is suitable for the weighing measurement of freight trains and the electronic modification of low cost of prime mechanical scales in large enterprises and railway freight depots, such as metallurgy, mines, harbors, etc.
Description
The utility model relates to train weighs and uses track scale, and refering in particular to is the dual-purpose automatic scale of a kind of sound attitude.
At present, domesticly be used for the equipment that train weighs and mainly contain dynamic electronic rail balance and static electronic track scale.Dynamic electronic rail balance is the large-scale weighing machine of a kind of energy measurement moving vehicle (train, as follows) weight and speed.Dynamic electronic rail balance has single weighing unit and two two kinds of forms of weighing unit on physical construction, no matter separate unit or its weighing unit length of two platform are generally below 4m, and this size mainly designs for identification vehicle automatically.Each weighing unit is used for the measure portion vehicle weight, and complete vehicle weight is generally obtained by twice above measurement result addition.More particularly, the train of China's operation at present is made of two bogies, is supported by four wheels on each bogie, and above-mentioned measuring method also can abbreviate the bogie metering system as.So the weight of vehicle can obtain by the trailing or leading bogie weight addition that will measure, metering process need not manual intervention, so claim automatic scale again.Static electronic track scale weighing unit length, can be finished measurement and also claim the car load metering, so this metering system is disposable finishing when two bogies of tested vehicle are all on weighing unit generally greater than 10m.But this metering system requires that vehicle does not have relative motion with weighing unit in measuring process, and must manually write down measurement result.Thereby above-mentioned two kinds of device uses are convenient inadequately.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and processing and manufacturing is easy, the automaticity height, and the measuring accuracy height possesses dynamically and the dual-purpose automatic scale of sound attitude of static measurement function.
The utility model is to adopt following proposal to realize: it is by weighing unit, the rail of weighing, LOAD CELLS, the axletree identification sensor is formed, described weighing unit bottom is provided with LOAD CELLS, be provided with the rail of weighing above the weighing unit, on weighing unit, at least be provided with one group by infrared switch, induction type is near switch, pressure transducer, the axletree identification sensor of a kind of formation in the shear force sensor, the signal of LOAD CELLS and the collection of axletree identification sensor is imported external computer processing system simultaneously, realizes moving vehicle, static weighing is measured, show.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:
Accompanying drawing is a structural representation of the present utility model.
See accompanying drawing, the utility model is made up of weighing unit 1, the rail 2 of weighing, LOAD CELLS 3, axletree identification sensor 4, described weighing unit 1 is arranged with some LOAD CELLS 3, the rail 2 of weighing is arranged at above the weighing unit 1, at least be provided with one group by infrared switch on weighing unit 1, induction type is near the axletree identification sensor 4 of a kind of formation in switch, pressure transducer, the shear force sensor.
Principle of work of the present utility model is sketched in down: when lorry to be weighed enter weigh after, LOAD CELLS produces with the proportional electric signal of weight and imports external computing machine, simultaneously, the axletree number signal that the axletree identification sensor collects is also imported external computing machine, computing machine is handled in real time to this two data-signal, can draw the weight and the speed of a motor vehicle of lorry.The utility model is owing to be provided with the axletree identification sensor on weighing unit, therefore, but the The real time measure speed of a motor vehicle, identification type of vehicle and measurement car weight, realize the kinetic measurement of vehicle multiparameter, satisfy the requirement of large enterprise such as mine, metallurgy, harbour and railway goods station, improve the train operation economic benefit the goods train dynamic weighting; In addition, to the static measurement of the weight of train, the utility model obviously can be competent at, and therefore, the utility model can be realized the dynamic and static measurement to the weight of train.
In sum, the utility model is simple in structure, weighing is accurate rapidly, working stability is reliable, the operation effect is convenient, installation and maintenance are simple, being applicable to the Weighing of goods train of large enterprise such as metallurgy, mine, harbour and railway goods station and the low-cost electronic reformation of former machinery weighing apparatus, is to improve enterprise's labour productivity, raises the management level and the advanced metering outfit of economic benefit.
Claims (2)
1, the dual-purpose automatic scale of sound attitude, comprise weighing unit 1, the rail 2 of weighing, LOAD CELLS 3, axletree identification sensor 4, described weighing unit 1 is arranged with some LOAD CELLS 3, the rail 2 of weighing is arranged at above the weighing unit 1, it is characterized in that being provided with at least on weighing unit 1 one group of axletree identification sensor 4.
2, the dual-purpose automatic scale of sound attitude according to claim 1 is characterized in that axletree identification sensor 4 by infrared switch, and induction type is near a kind of formation in switch, pressure transducer, the shear force sensor.
