Description
Technical field
The utility model 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 checkout equipment, is mainly used in the metering of the Weight Loaded of railway freight car and super, unbalance loading detection.
Background technology
The current dynamic weighting for railway freight car Container Loading weight or dynamically super, unbalance loading Weighing adopt automatic scale or railway freight-car Super leaning load checkout gear usually.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.No matter be without beam type automatic scale or railway freight-car Super leaning load checkout gear, structurally all need to be arranged on rail track and could realize.Similar to the structure of railway freight-car Super leaning load checkout gear without beam type automatic scale, its main distinction is, railway freight-car Super leaning load checkout gear is directly installed on (as shown in Figure 1) on the railway ballast of rail track, then will be arranged in the concrete foundation of rail track (as shown in Figure 2) without beam type automatic scale.
Above-mentioned railway freight-car Super leaning load checkout gear and being made up of rail, sleeper, sleeper basis (railway ballast or concrete foundation) and railway roadbed without the rail track that beam type automatic scale is installed.In addition, in response to the requirement of rail track communication signal transmissions, certain DC voltage should be had between two one steel rails of rail track (on the regular rail track especially for operation), therefore, keep the insulation between rail track two one steel rail to be very necessary.
Early stage railway freight-car Super leaning load checkout gear adopts steel work sleeper, is easy to like this install LOAD CELLS.But steel work sleeper is easy to be subject to ambient temperature or humidity effect and corrodes.Particularly at southern sough or coastal region, because appropriateness is comparatively large, steel work sleeper is easily corroded.When after the corrosion that steel work sleeper occurs to a certain degree, the insulation between rail can not be ensured, make rail track communication signal transmissions be subject to certain impact, be even difficult to the transmission realizing signal.Along with the development of railway equipment technology, ordinary concrete sleeper obtains transformation, and after installing pressure sensor additional, meet the insulating requirements of rail track.But because this transformation changes the geometric shape of sleeper, this cannot meet the technical requirements of railway relevant department to railway permanent ways maintaining, under particularly railway permanent ways maintaining adopts the background of do mechanization operation at present, therefore bring certain difficulty to railway permanent ways maintaining.
And for without beam type automatic scale, because its steel work sleeper is embedded in concrete foundation, when steel work sleeper is corroded, the application life that certainly will will reduce without the whole device of beam type automatic scale.
To sum up, be therefore necessary to transform to railway freight-car Super leaning load checkout gear or without the steel work sleeper in beam type automatic scale.
For the regular sleeper in rail track, its effect supports circuit rail, and its support for circuit rail has three kinds of mode: A usually, supported on both sides; B, mid portion supports; C, all supports.For these three kinds of situations force analysis as shown in figs. 3 a-3 c, wherein M1, M2 represent moment of flexure.In common line, sleeper is usually in C and all supports or A supported on both sides, and particularly without in beam type automatic scale equipment in station, sleeper is usually in C and all supports.
Common III type prestressed reinforced concrete tie profile as shown in Figure 4 A and 4 B shown in FIG..Owing to detecting on checkout gear or the sleeper without (as shown in Figure 1, 2) in beam type automatic scale surveyed area and need to install LOAD CELLS being in railway Super leaning load lorry, this just needs transform the shoulder block part of ordinary concrete sleeper and install LOAD CELLS additional, the result of such improvement is that sleeper height is increased, and this will affect rail track machinery maintenance; If remove shoulder block part to install LOAD CELLS additional again, confirm through practice, the result improved like this is the compressive strength by reducing sleeper.
Therefore, no matter existing be railway freight car Super leaning load checkout gear or without beam type automatic scale, there is following problem: steel work sleeper susceptibility-to-corrosion; Only the shoulder block part of common pre stressed concrete sleeper is transformed and the technical requirements of rail track mechanized maintenance can not be met after installing sensor additional.Therefore, need withstand corrosion and still can meet a kind of sleeper of the technical requirements of rail track mechanized maintenance after improving.
