Abstract
A rail transit electric conduction rail turnout type end portion bend comprises a bend body (1) which is provided with a radian consistent with a curve of a rail along the route direction. A collector plate (2) is fixed on the rail top surface of the bend body (1), extends towards one side which is far away from a route, and the center of a collector surface is enabled to be deviated from one side which is far away from the route. The bend body is provided with the radian consistent with the curve of the rail along the route direction, limiting requirements at a turnout zone, a turnout crowd zone and other places can be met, the fracture length in the turnout zone and the turnout crowd zone is reduced, the occurrence that the fracture distance of an electric conduction rail exceeds the largest length between locomotive collector shoes due to the limitation is avoided, the phenomenon that power-lossing of a locomotive is caused and normal running is affected due to the fact that the collector shoes are connected to a fracture in a missing mode is prevented when the locomotive passes by.
Description
Technical field
The utility model belongs to the power supply of urban orbit traffic technical field, is specifically related to a kind of track traffic conductor rail track switch type end bends.
Background technology
In urban track traffic the 3rd rail electric power system, arrangement is in a side of circuit, and in track switch place, Cha Qun district domestic demand the nature fracture is set, and fracture seamlessly transits by end bends realization locomotive.Because there is strict gauge requirement the circuit both sides, and existing end bends is straightened condition along the circuit direction, and is bigger to requirements of installation space, so conductor rail just needs to disconnect at the track switch place prematurely, causes fracture bigger.If fracture length exceeds the ultimate range between the locomotive collector shoe, locomotive may be connected in the fracture by sky through out-of-date, causes the locomotive dead electricity, and influence is operation normally.
Summary of the invention
The technical matters that the utility model solves: design a kind of track traffic conductor rail track switch type end bends, have the radian consistent with rail curve along the circuit direction, not only can satisfy the gauge requirement that track switch, Cha Qun district etc. locate, and reduced the fracture length of conductor rail in track switch, Cha Qun district, and to avoid owing to the gauge reason, conductor rail fracture distance exceeds the extreme length between the locomotive collector shoe, prevent that locomotive is through out-of-date, the collector shoe sky is connected in the fracture, causes the locomotive dead electricity, and influence is operation normally.
The technical solution that the utility model adopts is: a kind of track traffic conductor rail track switch type end bends, comprise the elbow body, described elbow body has the radian consistent with rail curve along the circuit direction, fixedly award the stream plate on the tread face of elbow body, and award the stream plate and award stream interface center deflection away from circuit one side to extending away from circuit one side, making.
The described stream plate of awarding adopts Steel-aluminium composite board to make, and makes aluminum layer and elbow body tread bottom surface closely connected, and the corrosion-resistant steel flaggy is for awarding stream interface.
Be shaped on connecting bore on the horizontal segment of described elbow body, the perk section is shaped on groove in the flange of rail one side, and in the groove T-shape piece is arranged fixedly.
The advantage that the utility model compared with prior art has and effect.
1, the utility model has the radian consistent with rail curve along the circuit direction, not only can satisfy the gauge requirement that track switch, Cha Qun district etc. locate, and reduced the fracture length of conductor rail in track switch, Cha Qun district, avoid owing to the gauge reason, conductor rail fracture distance exceeds the extreme length between the locomotive collector shoe, prevents locomotive through out-of-date, and the collector shoe sky is connected in the fracture, cause the locomotive dead electricity, influence is operation normally.
2, the utility model is awarded stream interface center deflection away from circuit one side, the area of contact of having awarded stream interface and locomotive collector shoe when having increased locomotive by segment of curve, guarantee to award flow smooth and easy.
3, the utility model is fixedly awarded the stream plate at the tread face, and awards the stream plate and adopt Steel-aluminium composite board to make, and makes to award stream interface and have good resistance to abrasion and corrosion stability etc., and has excellent electric conductivity; Not only improve the service life of product, and saved cost.

The specific embodiment
Below in conjunction with accompanying drawing 1-5 a kind of embodiment of the present utility model is described.
A kind of track traffic conductor rail track switch type end bends 9, comprise elbow body 1, described elbow body 1 has the radian consistent with rail curve along the circuit direction, and fixedly award on the tread face of elbow body 1 stream plate 2, and make award stream plate 2 to extending away from circuit one side.The described stream plate 2 of awarding adopts Steel-aluminium composite board to make, and makes aluminum layer 6 and elbow body 1 tread bottom surface closely connected, and corrosion-resistant steel flaggy 7 is for awarding stream interface.Said structure makes awards stream interface center deflection away from circuit 8 one sides, the area of contact of having awarded stream interface and locomotive collector shoe when having increased locomotive by segment of curve, guarantee to award flow smooth and easy.In addition, Steel-aluminium composite board adopts explosion welding technique, at surface of aluminum plate soldering stainless steel plate, obtains the fluid layer of awarding of characteristics such as high-wearing feature, highly corrosion resistant, high conductivity, has further guaranteed to award the smooth and easy of stream.
Be shaped on connecting bore 3 on the horizontal segment of described elbow body 1, be used for being connected with common conductor rail; The perk section is shaped on groove 4 in the flange of rail one side, and T-shape piece 5 is fixedly arranged in the groove 4.Be connected and fixed end bends 9 by T-shape piece 5 and insulating support, and certain amount of raising arranged to guarantee that collector shoe passes through smoothly in the perk section.
The utility model both can be installed in the segment of curve inboard, also can be installed in the segment of curve outside.The utility model not only is applicable under the conductor rail and contacts mounting means, equally also is applicable to contact mounting means on the conductor rail.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, so all equivalent variations of being done with the described content of the utility model claim all should be included within the utility model claim scope.
