Abstract
The utility model provides a single beam railroad scale which adopts the single beam under the steel rail as the bearing beam and replaces the conventional railroad scale platform. The single beam railroad scale includes a guide rail and a weighing rail positioned in the concrete foundation and a bearing beam and a weigh sensor positioned under the weighing rail; the weighing sensor is connected with the data collection system. Wherein, the guide rail and the weighing rail can be connected in the rail breaking way, the joint of the guide rail and the weighing rail are connected by a taper, so as to reduce the impact of the vehicle wheels on the joint; the guide rail and the weighing rail also can be connected in the rail non-breaking way, by adopting a shear sensor positioned in the rail waist to distinguish the guide rail and the weighing rail. The model costs low, has good applicability, can be made into a static railroad scale as well as a dynamic railroad scale; can be single platform as well as double platform and multi platform. The line does not need to be cut when excavating small foundation and casting concrete, without impacting the running operation and safety.
Description
Technical field
The utility model relates to a kind of weighing-appliance of grasping charge of trucks weight of checking, relates in particular to a kind of track scale that is used to detect the railway freight-car Weight Loaded.
Background technology
Railway interests uses track scale as metering outfit in order to check the Weight Loaded of grasping lorry usually.Track scale is through years of development, from the mechanical type progress to all electronic, from the static state progress to dynamically, single table surface, many table tops have appearred, progressive from huge basis to foundation-free, and measuring accuracy improves constantly, and the way of output is advanced more, bring great convenience for the transportation by railroad and the owner of cargo, also provide convenience for the statistical management of industrial enterprise.But bulky, shortcomings such as the basis is huge, installation palpus disrupted circuit influence driving that existing track scale also exists.
Through the deep study and analysis to existing track scale, we think, no matter these track scales are static, dynamically, table top quantity has all adopted the aufbauprinciple of truck mounted track scale, with whole table top as carrier, attachment rail in the above again, below sensor installation.There is following drawback in this structure: 1, table top is general huge heavy, has increased equipment investment, has also increased initial load to sensor; 2, table top will be stablized, and the sensor more than 4 must be arranged, and as plane body, constraint more than three promptly becomes hyperstatic structure, and dynamometry mechanism is complicated, particularly requires very high to the basis, dark and thick whole huge basis must be set, the investment that has increased track scale; 3, owing to huge basis, necessary closed-loop influences normal hauling operation during construction and installation.In fact, the design feature of rolling stock is that " wheel to " has fixing distance, at the table top upper edge of track scale rail moving linearly, is in plane motion unlike automobile on truck scale, therefore need not whole table top, as long as two " beam " is just passable.In view of the above, we have proposed the imagination of " single-beam formula track scale ".
Summary of the invention
The purpose of this utility model provides and a kind ofly adopts single beam under the rail as spandrel girder, replaces the single-beam formula track scale of common rail weighing apparatus table top.
Single-beam formula track scale of the present invention comprises being installed in approach rail, the check weighing rail in the concrete foundation ditch and being installed in spandrel girder and weight sensor under the check weighing rail that weight sensor is connected with data acquisition system (DAS).
Be provided with the cross spacing piece in the installation of the outside of check weighing rail, prevent that it from laterally moving; Limit it at approach rail upper edge rail assembling rail clamps and vertically move,, thereby guarantee measuring accuracy with the stability of assurance check weighing rail and check weighing amount.
Approach rail can adopt broken rail to be connected with the check weighing rail, and approach rail is provided with the compound transition that is connected with fish platee with the seam crossing of check weighing rail.This compound transition comprises outside transition and the inner transition device that is arranged on approach rail and check weighing rail both sides.When outer sensors on the pressure wheel during in the seam of approach rail and check weighing rail, wheel presses inner sensors simultaneously, has eliminated vibration and the impact of wheel at seam crossing.
Approach rail and check weighing rail also can be realized continuous rail, and employing is installed in the shear force sensor district of the web of the rail or a board-like pressure transducer is installed under approach rail is distinguished approach rail and check weighing rail.
When check weighing function of the present utility model is achieved in that wheel when lorry is to the track scale approaching, wheel presses the approach rail at track scale two ends earlier, compress the transition 2 of approach rail and check weighing rail 1 seam crossing, to eliminate wheel the impact at rail gap place (or adopt continuous rail form, at the web of the rail board-like sensor regions is installed under shear force sensor or the rail and divides circuit rail and check weighing rail).Wheel presses the check weighing rail fully then, measures the simulating signal of wheel weight by the beam lower sensor, through the data acquisition device acquired signal and through the A/D conversion, signal in the calculator memory storage, handle, calculate single wheel load or a plurality of wheel load.About the data addition of two strands of check weighing rails to get shaft heavy or bogie is heavy, 4 additions draw complete vehicle weight.
Design feature of the present utility model is: adopt the single beam under the rail to replace the table top that common rail weighs as spandrel girder, LOAD CELLS is set under spandrel girder measures wheel or bogie weight.After being equipped with suitable data vasculum and software program, this track scale can the static test car weight, also can realize dynamic test, the continuous car of crossing, and check weighing car number is not limit.According to the length of table top, test speed can be from 3km/h to 20km/h, and measuring accuracy can reach 0.5~1%.
Therefore, single-beam formula track scale of the present utility model compared with prior art has the following advantages:
1, the utility model has been cancelled the table top of huge heaviness, has reduced the quantity and the concrete volume of foundation excavation, has reduced the overall cost of equipment, makes the price of separate unit track scale only be equivalent to 1/2 to 1/3 of common rail weighing apparatus.
2, the utility model all needn't disrupted circuit at excavation small-sized basis and casting concrete, does not influence vehicling operation and safety.
3, the utility model can be as required, can make " broken rail " to improve measuring accuracy, also can make " not broken rail ", be installed in the rail web of the rail or rail with shear force sensor and separate test section and non-test section with board-like sensor down, so that the raising test speed, the impact when reducing car.
4, the utility model adaptability is strong, can make static state railroad track scale, also can make dynamic railway truck scale; Based on the bogie metering, can be single table surface, also can be two table tops, many table tops etc.
