Description

The invention relates to an intermediate section for changing the wagon wheel gauge, used in the passage of tracks with different gauges, of wagons whose bogies are provided with adaptive rolling assemblies.

There is a device for changing the track (RO 65612) consisting of two sections of movable carrier rail, interspersed between three sections of fixed carrier rail, and a guide rail for positioning the axle, so that it remains always on the axis of the track, even if the wheels are loose and axially displaceable.

The device also includes a rail that controls the latch / disengagement maneuver. The vehicle travels the route made up of sections that define the action and the sequence of the working phases of the device.

The action takes place automatically, while the train gasket is in motion and consists of the following sequence of operations: the fading of the safety system, the distance / approach of the wheels, the locking in the final position, having the characteristic that the wheels move along the axle is done once with the displacement of the rails on which they roll.

Their main disadvantage is the low reliability of moving track areas.

There is also known a device for changing the track (EP 596408), where, during the sliding and sliding along the axle of the wheels widened with sliding bearings, the entire weight distributed of the wagon is taken over by a pair of auxiliary rails over the raised ones. rolling, which rolls two pairs of auxiliary wheels, for each bogie. at the moment of being engaged on the raised part, the axial unfolding of the groups of wheels also occurs and by means of suitable guidance the change of the track is made, after which, at the exit from the raised area of the auxiliary rails, the axial lock is made.

The main disadvantage of this type of device is the need to equip all the bogies with auxiliary wheels, which are useful only on the gauge changing portion.

The technical problem, which is solved by the invention, consists in automatically carrying out the passage from a railway section with a track, to another with another track, by guiding and locking it securely, without discharging the radial load axle in as long as possible. short.

The intermediate section for changing the gauge of the wagon wheels, by working with the adapted axles, (according to the CBI of 2002 00530), eliminates the above disadvantages, solving the technical problem posed, in that it consists of a metal frame, equipped with two inclined rails. symmetrically in the horizontal plane with a sufficiently small angle, so that the gauge change is smooth and in motion. The inclined rails are framed between two pairs of struts with the U-section on which are fixed some active members, some slides or rollers, which actuate the wheels approaching or pushing them away, as the case may be, on the axle to the desired height, on the line in which the wheels are locked on the axle by claws with claws, driven by rackets with large teeth placed on the metal frame in the direction of the couplings. The wheels are unlocked at the junction of the rails, positioned at the beginning of the section, followed by their locking and thus remaining until a new gauge change.

By applying the invention, the following advantages are obtained:

- smooth and safe passage from one track to another;

- firmly lock the wheels on the track;

- increased reliability of active organs;

- the possibility of easy replacement of worn parts.

The intermediate section for changing the gauge of the wagon wheels, according to the invention, is composed of a metal frame A with rails inclined symmetrically to the forward direction with an angle a, small enough for the passage to be smooth, located between the 23-ton wheelbase. by rail with different gauges, which will pass, in order to automatically change the gauge, the wheels B of a bogie (according to the CBI of 2000 - 00530, with which it creates 25), having the width (a) a wheelbase (b), with axle boxes C, with axles D equipped with clamps E with claws, which are driven by racks 1, fixed by the crossbars 27 of frame A, in the direction of the teeth of the couplings E on the axle. By rolling, the E couplings with claws self-release and by rotation, they lock the wheels in the position brought by the section guides, thus maintaining them until a new gauge change.

The metal frame A, having the dimensions L, c, d and L _1; L ₂ and e _1t e ₃ functional, 31 is composed of base plates 1 on which rails 2 are welded symmetrically horizontally with an angle α resulting from the ratio ((e ₃ -e ₁ ) / 2) L ₁ = tg a, between two pairs of 33 struts 3 with a U-profile closed with some side wings 4 connected by some sleepers 5 and some ribs 6 welded on the rail. 35 In a first embodiment of the invention, between the bars 3 welding plates 7 are welded, on which are mounted wear plates 8 with screws 9. 37 in a second embodiment of the invention, between the bars 3, Instead of the support plates 7, a prism 10 is welded with semicircular seats in which some rollers 11 39 are retained on the prism 10 through a profiled bar 12, with some screws 13. On the crosspiece 5, welds are supported 14 in the direction of the couplings. It is on the D-axle and on the junction line F, where 41 begins the approach or separation of the rails 2, on which are mounted some rack 15 with large teeth, fixed by means of pins 16 and with some screws 17. The rack 15 is provided 43 with two large teeth, and the gear teeth E with 12 teeth, which will rotate at an angle β = 60 * necessary to lock and unlock the wheels at the desired point and moment. 45

RO 120000 Β1

The wheel gauge is replaced by the intermediate section as follows: when each D-axle is reached with the wheels on the junction line, when moving from the large to the small track, the teeth of the rack 15 rotate the rotating part of the coupling E by 60 °, unlocking the wheels that will be close to the intermediate gauge e ₂ , or the small one _{1 (} in which it travels to another point of change. When moving from the small gauge to the large gauge, at the entrance to the starting line of the wheel clearance, the guides move the wheels to the line). junction, where the track starts with the next gauge, at which point the teeth of the rack 15 rotate the rotating part of the couplings E by 60 °, bringing into the active area two claws with the required dimension of the respective gauge, in which the wheels will remain locked.

The section A of the section can be integrated in solidarity between the sections of track with different gauges at the point of change in the terminals of railways, the combined transport or by ferry at the entrance or exit of it.
