Abstract
The utility model discloses a docking device of a train rail. The docking device of the train rail belongs to the technical field of railway docking, wherein the front end of a rear segment rail and the rear end of a front segment rail are connected with an inner connecting plate and an outer connecting plate through bolts on a rail waist portion, the rear half portion of a square rail key is fixedly connected in an upper plane key slot arranged on the rail top of the rear segment rail through an inside hexagonal bolt with a pin nail from a down hole of the outer side surface of the rail top or is fixed through clamping force on the two sides, a key beam is arranged on the front half portion of the square rail key, and the key beam and a plane inner telescopic mouth of a front segment rail top of the front segment rail are bitten and connected in a sliding mode. The docking device of the train rail is substantially used for docking of various train rails, docking of high-speed train rails and docking of train-set train rails.
Description
Technical field: the utility model relates to a kind of docking facilities of train rail, belongs to railway docking technique field.
Background technology: the docking facilities of existing train rail, it mostly is the joint at prosthomere track and deutomerite track, be provided with installing hole by the waist between tread and the foot, the waist that prosthomere track and deutomerite track joint separate the shrinkage joint is connected to each other fixing by interior side connecting plate and outer side connecting plate with bolt, the docking facilities greatest drawback of this class train rail is, the shrinkage joint of prosthomere track and deutomerite track is directly to disconnect, when Train Wheel is docked shrinkage joint by each, all produce the vibration of great-leap-forward, this vibration can make train produce and jolt and noise, and the travel speed of train is reduced.
Summary of the invention: in order to overcome the existing defective that the train rail butt joint exists, the utility model provides a kind of docking facilities of train rail.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the back segment track that has the back segment foot, the top of back segment track is the back segment tread, in the waist both sides of back segment foot and back segment tread front end are being connected and fixed with bolt side connecting plate and outside side connecting plate latter half of, the first half of interior side connecting plate and outer side connecting plate is being connected and fixed the leading portion track that has the shrinkage joint and the waist of leading portion foot with bolt, back segment track front end and leading portion track rear end are being crossed over shrinkage joint in-plane on back segment tread and leading portion tread and are being milled with keyway and flexible mouth, be connected and fixed or fixing with the square rail key on mutually the same plane of back segment tread latter half of with both sides folder power from tread lateral surface down-the-hole with the hexagon socket head cap screw that has pin in the keyway, square rail key first half is the key beam with mutually the same plane of leading portion tread, and the key beam is inner interlock with flexible mouthful and is slidingly connected.
The beneficial effects of the utility model are: can make the shrinkage joint of respectively docking in the train rail become full interlock by full disconnection; The travel speed of train is further improved; Can reduce vibration and the interior noise of car in the train operation; Can make the train energy-saving consumption-reducing and reduce running cost; Train and railway service life are prolonged synchronously.
Description of drawings: Fig. 1 is a kind of docking facilities schematic diagram of train rail
Below in conjunction with drawings and Examples the utility model is further specified.
Among the figure: 1, back segment track; 2, back segment tread; 3, square rail key; 4, shrinkage joint; 5, flexible mouthful; 6, leading portion tread; 7, leading portion track; 8, leading portion foot; 9, key beam; 10, keyway; 11, back segment foot.
The specific embodiment: Fig. 1 shows embodiment of the present utility model.The docking facilities of a kind of train rail as shown in the figure, comprise the back segment track (1) that has back segment foot (11), the top of back segment track (1) is back segment tread (2), in the waist both sides of back segment foot (11) and back segment tread (2) front end are being connected and fixed with bolt side connecting plate and outside side connecting plate latter half of, the first half of interior side connecting plate and outer side connecting plate is being connected and fixed the leading portion track (7) that has shrinkage joint (4) and the waist of leading portion foot (8) with bolt, back segment track (1) front end and leading portion track (7) rear end are being crossed over shrinkage joint (4) and are being milled with keyway (10) and flexible mouthful (5) at back segment tread (2) and the last in-plane of leading portion tread (6), be connected and fixed or fixing with the square rail key (3) on mutually the same plane of back segment tread (2) latter half of with both sides folder power from tread lateral surface down-the-hole with the hexagon socket head cap screw that has pin in the keyway (10), square rail key (3) first half is the key beam (9) with mutually the same plane of leading portion tread (6), and key beam (9) is inner interlock and is slidingly connected with flexible mouthful (5).
During work, the train track is along with the continuous variation of the four seasons and day and night temperature, each back segment track (1) front end and each leading portion track (7) rear end have formed one by the expand with heat and contract with cold shrinkage joint (4) of action gap of the temperature difference, when the train rail expanded by heating extends, shrinkage joint (4) reduces, fixing in the keyway (10) of back segment track (1) front end tread (2) in the square rail key (3) flexible mouthful (5) pushing leading portion tread (6) to that the key beam (9) of first half is parallel, train wheel can be stably successively by the same back segment tread (2) of going up plane back segment track (1), square rail key (3), the leading portion tread (6) of key beam (9) and leading portion track (7); Catch a cold when train rail and to shrink when shortening, open greatly at shrinkage joint (4), integral rails key (3) contracting backward that the key beam (9) of leading portion is parallel fixing in back segment track (1) front end tread (2) keyway (10) is moved back, make the front end flexible mouthful (5) of key beam (9) become big, when train wheel when the track that causes by shrinkage disconnects shrinkage joint (4), supported by back segment tread (2) and the same key beam (9) of going up the plane of leading portion tread (6), allow the wheel of train steadily pass through, train is travelled no longer in orbit produce vibration and jolt, when can make train energy-conservation, further speedup.The whole courses of work of docking facilities that above-described embodiment has formed a kind of train rail have realized task of the present utility model.
