Description
Technical field
The present invention relates to the device that railway is fixed with sleeper and railway roadbed, the sleeper that is specifically related to a kind of sleeper positioning link and is located by connecting and locates through this, belongs to sleeper technical field.
Background technology
Sleeper is to be often used to the indispensable material of carrying object in railway construction, the laying of dedicated track traveling equipment and load bearing equipment field.According to the difference of its composition material, sleeper is mainly divided into wooden sleeper, reinforced concrete sleeper, steel sleeper and composite material sleeper.
Once laying, sleeper successfully enters use, will bear for a long time pressure and vibratory impulse power that the locomotive of running at high speed such as train etc. brings, so above-mentioned any sleeper is when laying, all need to realize firm connection with railway roadbed, thereby realize fixing as far as possible fully sleeper, otherwise sleeper again constantly in the process of resilience, is easy to cause sleeper generation elastic deformation, thereby causes the catastrophic effects such as swollen road, runway after constantly bearing pressure and vibratory impulse power; Also be easy to because elastic deformation causes the connection between sleeper and railway roadbed destroyed, sleeper produced mobile, affect locomotive operation safety simultaneously.
In prior art, Chinese patent literature CN201713734U has announced a kind of T-shaped double-block type sleeper, one square-section sleeper baffle plate structure T shape in aggregates double-block type sleeper is set respectively in double-block type sleeper two outsides, because sleeper baffle plate is strengthened railway ballast lateral restraint, railway ballast particle mean effort reduces, reduce and have tiny fragments of stone, coal, etc. Roadbed subsidence and pulverizing, significantly strengthen sleeper lateral resistance, can improve track structure safety and track lateral stability.Sleeper both sides are extended and widened, railway ballast lateral restriction is strengthened, increase the vertical lateral resistance of sleeper.But above-mentioned T-shaped double-block type sleeper has been applicable to tiny fragments of stone, coal, etc. railway roadbed, it cannot be applied to concrete road bed, due to concrete road bed be integrated poured, between railway roadbed and sleeper friction not enough, resistance is inadequate, the problem that still existence and stability lacks, is difficult to play one's part to the full.
At present, fixing for the sleeper of railway ballastless track, fixture need to be set to be fixedly connected with sleeper with railway roadbed, such as Chinese patent literature CN2839343Y, a kind of buried sleeper is disclosed, in order to realize the fixing of sleeper and railway roadbed, this technology is provided with for connecting the double trapezoid reinforcing bar truss of sleeper and railway roadbed, build in concrete sleeper on the top of trapezoidal steel bar girder, stretch out outside concrete sleeper its underpart, described double trapezoid reinforcing bar frame is by two longitudinal reinforcements on upper strata, two longitudinal reinforcements of bottom and the oblique connecting reinforcement that longitudinal reinforcement location is fixed form.During use, by the bottom of the double trapezoid reinforcing bar frame of sleeper and concrete road bed cast-in-place, strengthen the connection of the two, be conducive to the fixing of sleeper.But, because trapezoidal steel bar girder is made as a whole sleeper and the railway roadbed of connecting, when locomotive passes through track fast, locomotive act on track so that the strength that acts on sleeper very large, these power can further be applied on trapezoidal steel bar girder, make as a whole steel bar girder and directly bear this active force, when locomotive passes through track, steel bar girder integral body is born active force down, and when locomotive is by after track, steel bar girder can whole resilience; Because said structure cannot slow down rebound effect as much as possible or eliminate, so after repeated multiple times above-mentioned such mechanism, trapezoidal steel bar girder is easy to occur whole distortion or damage, cause its whole stability to reduce, thereby affected the sleeper of its connection and the stationarity between railway roadbed.
Summary of the invention
Technical problem to be solved by this invention is in prior art after Reusability, easily because of stressed, to occur that connector deforms or damages for the fixing structure of the connector of sleeper and railway roadbed, cause its stability to reduce, affect the problem of the stable connection between sleeper and railway roadbed, and then provide a kind of and can realize the positioning link that still can keep sleeper to be fixedly connected with railway roadbed after Reusability.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A positioning link, it comprises the connection bracket that connects railway roadbed and sleeper;
Upper shield, described upper shield has the cavity of one end sealing, in described cavity, counterpart is set, and described counterpart is suitable for being connected with described connection bracket top;
Between roof in described cavity and the top of described connection bracket, have gap, the height in described gap is 3-10mm.
Described connection bracket top has external screw thread; Described counterpart is nut, and described nut is suitable for being connected with the external screw thread on described connection bracket top.
Described counterpart and described cavity inner wall matched in clearance, the top of being convenient to described connection bracket is connected with described counterpart, and described counterpart can be along described cavity inner wall longitudinal sliding motion.
The height in described gap is 5mm.
Described connection bracket is herringbone.
