SE546603C2 - LONGITUDINAL GRINDER FOR BALLASTED RAILWAY TRACK - Google Patents

Abstract

The problem: Development is fast and the infrastructure must not prevent the railway from increasing its load capacity, etc., if necessary. The solution: Utilization of available, known innovative technology for auto-adjustment, as well as added redundancy, robustness, margin for increased future requirements. Unique and innovative† The device: A system for ballasted railway tracks, with approximately 2.4 m long, rigid, along the track, longitudinal sleepers (8), the underside of which has one level, including transverse 2 peripheral support surfaces (1) and one centric (2), as well as skirts (3), plus two levels, including 4 cavities (4) and (9), for the rail (rail), a groove (5) along the sleeper, where the sleeper is provided with vertically protruding lugs (6) and (17). Advantages: With a safely calculable margin, safely calculable and redundant support surfaces against the ballast bed are ensured, in x-, y- and z-joints. The sleepers can certainly be oversized. For a marginally increased price, the entire transport system is provided with increased quality, as well as increased capacity and utilization. Area of application: Railway tracks for, from lowest to highest axle loads, etc.

(i) and one, central, sleeper, no. (2), where all of these are said sleepers (i, 2), each including a pair of said wings (20). on the one hand, the underside has longitudinal and transverse edges (3) and where, the underside of the lifeline has cavities (4) and (9), the upper sides of which form the bottom of the sleeper, - where each of the cavities (4, 9) longitudinal side edges form parts of side edges on the longitudinal edges (3), where the longitudinal side edges of the adjacent cavities form side edges on a longitudinal side, where the fourth side edge of the cavities (4) longitudinally borders the longitudinal slots (1) and where the fourth side edge of the cavities (9) longitudinally borders the longitudinal slots (2), ° where, between the longitudinal wings (20), along both longitudinal peripheries of the lifeline (22), the longitudinal edges run, - where the longitudinal edges lie in the case, between the above-mentioned longitudinal slots (1,2), ~ where, along the entire The upper side of the sleeper, near the longitudinal center line, runs a groove (5), Requirement 2 Device according to Requirement i, where the sleepers have a limited length, in the order of 2.4 m, Requirement Device according to Requirement i, where the cavileles (9) exhibit a greater height (24) than the cavileles (4) and the underside of the sleeper, therefore, exhibits different levels, 3. Claim 4 Device according to Claim 1, Where the said edge (5) has lugs (6, 21, 17), partly ~ longitudinal lugs (6, 21), five pairs, lying on a straight line, and partly lvlong lugs (17), two peripheral pairs, each of which, respectively. common line lies on a line and about i8 cm from each peripheral edge of the sleeper (8), 4. Requirements Device according to Requirements 1 and 4, where a central ridge (21) lying on the sleeper (8) is approximately twice as long as each of the other four longitudinal ridges (6). 5. A device according to claims 1, 4 and 5, on both sides and in direct connection with said longitudinal ridge (5) a ball bearing having five separate, higher than said ball bearing, located, in a vertical plane, on the support (16), where the respective longitudinal centerlines of the support are in line with one, one of said longitudinal ridges ( 6. , transverse centerline. Device according to claim 1-6, where the ball on said groove (5), as well as the ball on the extension wire (16) and the top of said collar wire (6,1 7, 21) are arranged in a similar manner laterally, from a high beam side, or a low beam side. Device according to claim 1 - 7, which per beam, on the end, the side of the beam, symmetrically, around the transverse centerline of the sleeper, exhibits 2 groups of internal, intermediate, threads (15). Device according to claims 1, 2, 4, 5 and 7, where a rubber cloth (18) is placed on the ball of said trough (5), having a slope, for said 5-fold collar (6, 2l), - a thickness, in the vertical direction, which exceeds the height of the collar (6, 17, 2)) and - with the length as the length between the four points of said peripheral, transverse collar (i 7. - and an overlying surface, the inclination of which is the same as that reported in Section 7 and is also in equal inclination, from the height of the sleeper to its lying side. Section 10 Device, according to Section 1, where the aforementioned 4 longitudinally extending sections (3), each, at the corner (4), has a longitudinal extension (23).
