Description

The inventive device relates to the field of elevated transport rail tracks and is used for passenger and freight traffic.

The prior art single-rail and double-rail cableways. The disadvantage of such roads is that in their device in suspension there is not only a rail track, but also all the wagons of its rolling stock.

An analogue of the invention is such a double-track suspension according to the copyright certificate SU 43019, AB 61 3/00, 05/31/1935.

The analogue has the following device. A cable is pulled in the center of the double-rail suspension, which is suspended from the tops of the A-shaped intermediate supports. Suspensions are suspended to this cable with certain intervals along the entire length of the rail track, to the lower ends of which there is a track beam, which is made in cross section in the form of a beam, on each console of which there is one track rail so that their symmetries intersect each other . The rollers of the running trolleys are supported on track rails. A carriage of rolling stock, in turn, with aerodynamic stabilizers and a propeller of an air screw propeller, is pivotally suspended from the undercarriage in turn (one floor below).

The device of the analogue, declared in 1935, for a number of reasons, is not industrially applicable. Here are just a few of these reasons.

1. Suspension of a rail beam on flexible cables is carried out along the entire length in one vertical plane and, therefore, with gusts of wind, the entire rail track is subject to pendulum (side) rolling. The movement of wagons even at minimum speeds along a swaying rail track under technical safety conditions is not allowed.

2. A wagon hinged to such a path (through the console of the trolley) has its own additional pendulum freedom of swinging on-board, which, according to the technical specifications for transport, is categorically industrially inapplicable.

3. The articulated support of the wagon turns such a device into scales, the load of which (including the mass of passengers) must be balanced along the entire route, which is practically not feasible and, therefore, is not industrially applicable.

A significant disadvantage of the analogue is that the location of the axes of symmetry of its track rails precludes the possibility of using in its device traditional time-tested designs of structural elements of rolling stock of public railways moving along track rails using propulsors made in the form of wheeled pairs.

The essence of the inventive double-rail suspension is that its rail base includes a continuous series of transverse fasteners, for example, in the form of sleepers, plates or beams, which form a common horizontal plane, on the surface of which there are two track rails in such a way that nowhere in in space, the axis of symmetry of one track rail does not intersect with the axis of symmetry of the second track rail.

The advantage of such a double-rail suspension system is that for the first time in the prior art, it becomes possible to move the rolling stock over the upper surface of the rail base and to carry out this movement using propulsors made in the form of wheelsets that are interconnected by one common axis.

Figure 1 of the attached drawing shows a fragment of a General view of the device suspension double-rail, side view.

Figure 2 shows a fragment of a General view of the device suspension double-rail, top view.

Figure 3 shows a cross section of a double-rail suspension device with a rolling stock car mounted on the surface of its track rails, having the ability to move on these rails using wheelsets.

The device of the double-rail suspension includes a rail track 1, on the surface of which two track rails 2 and 3 are located. The rail track is suspended above the ground on ropes 4 using suspensions 5 and 6, and the ropes 4 are suspended from two sides of the rail track on vertical supports 7. Suspensions 5 and 6, in order to increase the rigidity of the transverse fixation of the rail base, they also play the role of stretch marks and, therefore, are installed in space (as shown in FIG. 3) obliquely with respect to the axis of symmetry of the claimed device. The device of the suspension rail can include other stiffeners, made, for example, in the form of braces 8 and 9, with a fixed mount under the lower level of the rail base, for example directly on the ground or on the vertical support body, as shown in figure 3 of the attached drawing . The same figure shows the location of one of the cars 10 of the rolling stock, supported by track rails using a number of wheelsets 11.

The layout of the device, the principle of operation and operation of the rolling stock of the double-rail suspension does not have significant differences from the device, the principle of operation of the rolling stock when it is used on the railway lines of existing public and general purpose railways. An exception is the lack of need for off-season preventive, repair and restoration work at a distance of the subgrade road structure due to the absence of such a structural element in the claimed device. An exception is the lack of operational need to have the economy of a suspension double-rail track, an expensive arsenal of snowplows, because there is no need to free the structure of the roadbed from the snowdrifts (due to its absence)
