Description
Technical field
The present invention relates to railroad sleeper, particularly a kind of steel reinforced concrete composite construction sleeper, specifically, it is a kind of being arranged on without the steel and concrete structure sleeper device on beam type automatic scale, Super leaning load detection equipment, is mainly used in the metering of the Weight Loaded of railway freight car and super, unbalance loading detection.
Background technology
At present dynamic weighting or super, unbalance loading Weighing for railway freight car goods Weight Loaded generally use automatic scale or railway freight-car Super leaning load detection device.In automatic scale, what current Technical comparing was ripe and advanced is without spandrel girder automatic scale, also referred to as without beam type automatic scale.Either detect device without beam type automatic scale or railway freight-car Super leaning load, be structurally required for being arranged on rail track and could realize.Automatic scale without beam type is similar to the structure of railway freight-car Super leaning load detection device, it differs primarily in that, railway freight-car Super leaning load detection device is directly installed on the railway ballast of rail track (as shown in Figure 1), in the concrete foundation without beam type automatic scale rail track to be arranged on (as shown in Figure 2).
Above-mentioned railway freight-car Super leaning load detection device and the rail track installed without beam type automatic scale are made up of rail, sleeper, sleeper basis (railway ballast or concrete foundation) and railway roadbed.Additionally, requirement in response to rail track communication signal transmissions, should have certain DC voltage between two one steel rails of rail track (on the regular rail track especially for operation), therefore, it is the most necessary for keeping the insulation between rail track two one steel rail.
Railway freight-car Super leaning load detection device in early days uses steel construction sleeper, is so easily installed LOAD CELLS.But steel construction sleeper is susceptible to ambient temperature or humidity impact and corrodes.Particularly at south sough or coastal region, owing to appropriateness is relatively big, steel construction sleeper is easily subject to corrosion.After there is a certain degree of corrosion in steel construction sleeper, it is impossible to ensure the insulation between rail so that rail track communication signal transmissions is affected by certain, is even difficult to the transmission of signal.Along with the development of railway equipment technology, normal concrete sleeper is transformed, and meets the insulating requirements of rail track after installing pressure transducer additional.But owing to this transformation changes the geometric shape of sleeper, this will be unable to the technology requirement meeting railway relevant department to railway permanent ways maintaining, under railway permanent ways maintaining uses the background of do mechanization operation particularly at present, therefore bring certain difficulty to railway permanent ways maintaining.
And for without beam type automatic scale, owing to its steel construction sleeper is embedded in concrete foundation, when steel construction sleeper is corroded, the service life without the whole device of beam type automatic scale certainly will will be reduced.
To sum up, it is therefore necessary to railway freight-car Super leaning load detection device or transform without the steel construction sleeper in beam type automatic scale.
Regular sleeper in rail track, its effect is to support circuit rail, and it is generally of three kinds of mode: A, supported on both sides for the support of circuit rail；B, mid portion supports；C, all supports.For the force analysis of these three kinds of situations as it is shown on figure 3, wherein M1, M2 represent moment of flexure.In common line, sleeper is generally in C and all supports or A supported on both sides, and particularly without in beam type automatic scale equipment in station, sleeper is generally in C and all supports.
Common III type prestressed reinforced concrete tie profile is as shown in Figure 4 A and 4 B shown in FIG..Due to be in railway Super leaning load lorry detection detection device or without beam type automatic scale detection region in (as shown in Figure 1, 2) sleeper on need install LOAD CELLS, this is accomplished by transforming the shoulder block part of normal concrete sleeper install LOAD CELLS additional, so improve result be so that sleeper height increases, this will affect rail track machinery maintenance；If removing shoulder block part to install LOAD CELLS again additional, confirming through practice, the result so improved is the comprcssive strength by reducing sleeper.
Therefore, no matter existing be railway freight car Super leaning load detection device or without beam type automatic scale, there is problem below: steel construction sleeper susceptibility-to-corrosion；Only the shoulder block part to common pre stressed concrete sleeper can not meet the technology requirement of rail track mechanized maintenance after transforming and install additional sensor.Accordingly, it would be desirable to be able to it is corrosion-resistant and after improving, remain to meet a kind of sleeper that the technology of rail track mechanized maintenance requires.
Summary of the invention
It is an object of the invention to provide a kind of steel reinforced concrete composite construction sleeper, a kind of it is arranged on without the steel and concrete structure sleeper device on beam type automatic scale, Super leaning load detection equipment, is mainly used in the metering of the Weight Loaded of railway freight car and super, unbalance loading detection.
