Description

i1

The invention relates to railway transport, in particular to the connection of rail tracks laid on mobile articulated platforms,

The purpose of the invention is to increase reliability.

FIG. 1 shows a movable rail connection, a plan; FIG. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in FIG. one; in fig. 6 is a section d-d in FIG. one; in fig. 7 - Interaction of the Korobovy curve with a support at a roll of a platform.

The movable connection of the rails contains connected rails 2 arranged on articulated vehicles 1. At the ends of the connected rails 2 there is an annular support 3 and an annular support 4 which can be moved along the vehicle 1, the latter having a rectangular sole 5c fixed on there are spherical shaped bearings 6 installed in rectangular guides 7 mounted on a vehicle 1, and a rail section 8 having a groove 9 on its surface in contact with the protrusion 10 of the joined rail 2. Between the annular supports 3 and 4 there is an intermediate rail 11, the ends of which are provided with lugs 12, with which the intermediate rail 11 is connected by horizontal axes 13 to the brackets 14 and 15. And the brackets 14 and 15 present circular You are 16 and 17, entering respectively into ring otsors 3. and 4 and having a common axis of rotation with the latter in the vertical plane, with the supporting surface circular n.

You 17 represents the horizontal surface 18, and the cross section of the lower and side surfaces of the circular pin 16 in the perpendicular axis of the rail of the plane is formed by a duct curve 19 whose lateral surfaces are conjugated with a radius r with a horizontal plane 20, moreover, the radius r is made such that the annular support 3 with respect to the circular p-16 excludes the lateral gap between the contacting lateral surfaces and, in this case, causes the track of the movable joint to be

the absence of rails equal to the track gauging rails 2.

Mobile connection rails works as follows.

When the articulated vehicles 1 decrease or increase due to the absorbing devices of the couplings during driving, driving, braking, as well as in the radius of the railway track, the distance between the connected rails 2 increases. In this case, the bracket 15 on the one hand, connected to the intermediate rail 11 and on the other hand, through its circular heel 17, to the annular support 4, the sole 5, will move on the side bearings 6 of spherical shape into rectangular apravl guides 7 with 8 segments, compensating for a variable distance between the vehicle 1. In this case, the groove 9 of the rail segment 8 in contact with the projection 10 of the coupling rail 2, allowing in this case form a non-breaking path of variable length, which provides reliable transfer of the movable means. If the connected rails 2 are located at an angle to each other when the Articulated vehicles are in the curve of the railway track in the horizontal plane, the brackets 14 and 15 with circular heights 16 and 17 respectively provide for the rotation of the intermediate rail 11 necessary for the vehicle to pass from one transport - means 1 to another.

When the clamped rails 2 are located at an angle to each other, i.e. at different heights of articulated vehicles 1, caused by their different. loading in the vertical plane, the intermediate rail 11 with the help of horizontal axes 13 will rotate depending on the level difference at the required angle and ensure the continuity of the ends of the rails being connected 2.

Under uneven loading of one of the articulated vehicles, for example, in a storage hopper, when wooden sleepers are located on one side of the platform relative to the longitudinal axis of the latter, reinforced concrete sleepers are on the other side, and in other similar cases

due to spring suspension, the roll (tilt) of the platform in the more loaded direction.

Consider the work of one rail thread in this case.

The joined rail 2, inclined at an angle oL together with 6 spherical shapes mounted in a rectangular guide 7, 6, an annular support 4 with a bracket 15, an intermediate rail 11 and a bracket 14 rotated the same angle L with respect to the rail being connected 2, located on another articulated vehicle. The rotation is provided by rolling the support surface formed by the duct curve 19 of the circular bar 16 in the rigidly fixed annular support 3.

In the case of a roll of one of the articulated platforms, an intermediate rail 11, connected by means of a horizontal axis 13 with a bracket 14 and with the help of the latter with a circular heel 16, having in the plane perpendicular p

the axis of symmetry of the bracket, the support surface formed by the duct curve 19 will rotate in a rigidly fixed annular

with support 3, thereby forming the necessary angle of ° C, but without creating a forced torsion of the intermediate rail a 11 and without destroying the hinged fastenings of the intermediate

0 rail 11 to connectable rails 2.

In case of significant rolls of the vehicle; 1 means of rotation will occur due to the sliding friction of the support surface formed by

15 of the box-like curve 19 in the rigidly fixed support 3, which will lead to a slight increase in the forces in the hinged joints of the brackets 14 and 15 and will require increased wear-resistant 20 bones of the contacting surfaces. This can be eliminated by making sections of the lower and side surfaces of the circular bar 16 in the perpendicular axis of the rail of the plane with evolvent curves.
