Abstract
The utility model discloses a 43 kg/m ordinary rail railway switch capable of solving the problem of that the point end of the switch rail is easy to be worn and damaged because the present switch rails are all closed switch rails, so that the life time of the switch rail is shortened and derailment accident is easy to occur. The utility model comprises a stock rail 1 and a switch rail 2. From the point end 3 of the switch rail 2 made of ordinary steel to the upper end surface 4 where deformation occurs forms an isosceles triangle section, the side surface 5 of which is a slope shape, and the cross section 6 of which is an isosceles shape. The side surface 7 of the stock rail 1 joints the switch rail 2 and has an angular face shape which matching with the shape of the contact face of the switch rail 2. The point end 3 of the switch rail 2 is hidden within the rail gauge line of the stock rail 1. The switch rail 2 is provided with stiffening plates 8, 9 at two sides of the rail web, which are fixed on the switch rail 2 by connecting bolts.
Description
Technical field
The utility model relates to railway switch, especially belongs to ordinary steel rail railway turnout switch.
Background technology
Turnout switch system guiding train is along the rail track equipment of main track or side line direction running.The turnout switch that uses on the present railway, no matter be motor-operated switch or pneumatic track switch, be tongue and the stock rail mode that reclines, thin thin type formula is adopted at the tip of tongue, because its reasons in structure, so the deficiency that exists: owing to be the point end tongue, the point electrode of tongue is vulnerable to wearing and tearing and runs over and injure, this not only causes service life of equipment short, and is easy to generate the generation of rolling stock derailment accident, and economic loss is produced, caused in influence.
Technology contents
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of point-hiding tongue switch is provided, and makes the point of switch not by the wheel crushing, reduces the 43kg/m rail railway switch point-hiding railway switch of changing frequency and making the normal operation of train.
Realize the technical measures of above-mentioned purpose:
43kg/m rail railway switch point-hiding railway switch, comprise stock rail, tongue, it is that locating the upper surface that the upper surface begins distortion place from the tip by the tongue that common rail is made is isosceles triangle, the upper surface is that the side of isosceles triangle section is a domatic, the cross sectional shape of this section is an isosceles shape, side at the stock rail that pastes mutually with tongue is the inclined-plane, and match with the contact surface shape of tongue, the tip of tongue is hidden in the stock rail gauge line, stiffening plate is equipped with in tongue web of the rail both sides, fixes by connecting bolt and tongue.
Operating principle
When being 20 millimeters, the upper end face width of train by tongue be subjected to wheel side pressure with time side, top, when the upper end face width by tongue is 20～5 millimeters parts, be wheel side pressure transition section, when the upper end face width by tongue is 5 millimeters during with the lower part, the tip of tongue is owing to be hidden in the side gauge line of stock rail, so for not being subjected to train wheel pressure state section, train passes through smoothly.
Advantage of the present utility model is to make the point of switch not by the wheel crushing, reduce to change frequency and train is normally runed, and lowers cost of production, the generation of the incident that prevents that the train was derailed, and processing is simple.

The specific embodiment
Embodiment
Comprise stock rail (1), the 43kg/m rail railway switch point-hiding railway switch of tongue (2), in order to realize making the point of switch not by the wheel crushing, reduce the purpose of changing frequency and making the normal operation of train, the tongue (2) that to be made by common rail is located the upper surface (4) that upper surface (4) begins distortion place from most advanced and sophisticated (3) and is processed into isosceles triangle, and also upper surface (4) are processed as domatic for the side (5) of isosceles triangle section simultaneously, the cross section of this section (6) shape is processed as isosceles shape, the inclined-plane that matches with the contact surface shape of tongue (2) is processed in side at the stock rail (1) that pastes mutually with tongue (2), the upper surface (4) wide of tongue (2) is 5 millimeters and is hidden in stock rail (1) gauge line to most advanced and sophisticated (3) with the lower part that stiffening plate (7 is equipped with in tongue (2) web of the rail both sides, 8) fixing by connecting bolt (9) and tongue (2).
Operating principle
When being 20 millimeters, the upper surface (4) wide of train by tongue be subjected to wheel side pressure during with top fully, when the upper surface (4) wide by tongue is 20～5 millimeters parts, be wheel side pressure transition section, when the upper surface (4) wide by tongue is 5 millimeters during with the lower part, the tip (5) of tongue (2) is owing to be hidden in side (4) gauge line of stock rail (1), so for not being subjected to train wheel pressure state section, train passes through smoothly.
Claims (1)
1,43kg/m rail railway switch point-hiding railway switch, comprise stock rail (1), tongue (2), it is characterized in that the tongue (2) made by common rail locates the upper surface (4) that upper surface (4) begins distortion place from most advanced and sophisticated (3) and be isosceles triangle, upper surface (4) is that the side (5) of isosceles triangle section is domatic, the cross section of this section (6) is shaped as isosceles shape, side (7) at the stock rail (1) that pastes mutually with tongue (2) is the inclined-plane, and match with the contact surface shape of tongue (2), the tip (3) of tongue (2) is hidden in stock rail (1) gauge line, stiffening plate (8 is equipped with in tongue (2) web of the rail both sides, 9), fixing by connecting bolt (10) and tongue (2).
