Utility model content
Technical problem to be solved in the utility model is to provide a kind of wing rail veneer partition iron, and this interval iron can play the interval action of fastening wing rail panelling, ensures that wing rail panelling is not rolled partially, thus ensures that train safe passes through.
The technical scheme solved the problems of the technologies described above is:
A kind of wing rail veneer partition iron, it is multiple cylinder or cuboid steel work, interval iron cylinder or cuboid there is fastener hole along the axis of cylinder or cuboid, the axis of fastener hole and central body of frog central axis, the end face of interval iron cylinder or cuboid and the axis of fastener hole have the gradient, and the gradient is the end face of interval iron cylinder or cuboid and the plate face close contact of wing rail panelling.
Above-mentioned wing rail veneer partition iron, described interval iron is two covers, between the wing rail panelling that two cover interval iron are arranged on heart rail both sides respectively and heart rail, often overlap interval iron and comprise four interval iron, first interval iron, the second interval iron, the 3rd interval iron are cylindrical, 4th interval iron is cuboid, first interval iron, the second interval iron, the cylindrical end face of the 3rd interval iron have the gradient of 1:46.6, another end face has the gradient of 1:24, an end face of the 4th interval iron cuboid is arc surface, and radian is 5.02.
Above-mentioned wing rail veneer partition iron, the center of the fastener hole of described interval iron is corresponding with the fastener hole on the wing rail panelling be connected, the central axis of the fastener hole of the first interval iron and cylindrical central axes, the cylindrical central axis 7mm of center axis deviation of the fastener hole of the second interval iron, the center axis deviation its center axis 5.7mm of the fastener hole of the 3rd interval iron, the central axis of fastener hole of the 4th interval iron and the central axes of cuboid.
The beneficial effects of the utility model are:
The utility model is placed between the wing rail panelling of central body of frog both sides and heart rail, interval iron and wing rail panelling are fastenedly connected by fastening bolt, the interval action of fastening wing rail panelling can be played, can ensure that again wing rail panelling is not rolled partially, thus ensure the safety of train.The utility model is the matching component of high-strength wearable bainite wing rail panelling, can improve the application life of railway frog significantly.The utility model can solve former alloy steel frog application life short, need the frequent shortcoming changed, train generation off-line accident can be avoided.The utility model has that technique is simple, stable performance, low cost of manufacture, saving resource feature, there is good economic benefit and practical value.
