Description

The utility model relates to the field of rail transport using guides for moving, for example, railway and city transport, and more particularly to acicularless turnouts, containing a base on which a turntable adapted to rotate about the vertical axis is mounted, on which two pairs of transfer rails are located forming a rotatable translation unit, a rotary drive rotary platform, stops associated with the base, limiting the rotation in orotnoy platform and intended for use in the construction of branching rail tracks.

Shot-less switches have four times longer service life than wrenches. However, due to a number of significant drawbacks of their designs, they are still not in mass demand even in the domestic market. The elimination of these shortcomings will allow us to expand the scope of application of bezapostrovye crossless turnouts and increase the efficiency of track development of railways in general.

From the author's certificate SU 1649006 A1, ЕВВ 7/10, 05/15/1991 a cross-free crossless turnout switch is known. It describes a translation that contains connecting paths 1 and 2, double movable rails 3-6 with connecting rods 24 and 25 and a transfer mechanism, each of the movable rails being fixed at one end to a slewing ring and the other connected to a bar translation mechanism.

The disadvantage of this solution is the inadequate reliability of switching of a bezelless crossless switch, associated with the installation features, mainly at the installation site, which differs significantly from the factory conditions and does not ensure assembly accuracy.

The art is also known from the prior art for a cross-free crossless turnout switch comprising a base on which a rotary platform adapted for rotations about a vertical axis is mounted, on which two pairs of transfer rails are arranged to form a rotary transfer block, a drive that rotates the rotary platform, stops associated with the base limiting the rotation of the turntable. See copyright certificate SU 1567436 A1, B61L 5/02, ЕВВ 7/00, 05/30/1990. As the drive that rotates the turntable, the moving train itself is used, that is, the turntable is rotated at the moment the train passes through the section with a bezelless crossless turnout switch.

This decision is taken as a prototype of the proposed utility model.

The disadvantage of this solution is the insufficient reliability of switching switchless crossless switch, due to the fact that all this is mounted in place, and the inability to automatically remotely transfer the switch from one position to another in the absence of a train.

Based on this original observation, the present utility model mainly aims to offer a cross-free crossless turnout, which allows at least to smooth out one of the above disadvantages.

To achieve this goal, the base, turntable and drive are made in the form of a single unit, adapted for assembly in the factory. As well as a cross-free crossless turnout additionally contains a control system electrically connected to the drive.

Thanks to this, it becomes possible to manufacture a base, a rotary platform and a drive without a bezelless crossless turnout in the form of a single unit in the factory.

In addition, the control system, electrically connected with the drive, allows for remote switching of a needleless crossless switch, which occurs well in advance of the train entrance, which also increases reliability.

There is a variant of the utility model in which the drive is rigidly fixed to the base and kinematically connected to the turntable.

Thanks to this characteristic, it becomes possible to use large-sized drives or drives having a large weight as a drive.

There is a variant of the utility model in which the drive is rigidly mounted on a turntable and kinematically connected to the base.

Thanks to this characteristic, it becomes possible to use small-sized drives or drives having a low weight, and thus reduce the overall weight of the structure.

There is a variant of the utility model in which the drive is made in the form of an electric motor.

Thanks to this characteristic, it becomes possible to use the most common form of electrical energy to rotate the turntable.

There is a variant of the utility model in which the drive is made in the form of a hydraulic cylinder.

Thanks to this characteristic, it becomes possible to provide greater efforts with small dimensions than electric drives.

There is a variant of the utility model in which the control system includes limit switches located on the base or on the turntable, providing the generation of an electrical signal in the extreme positions of the turntable.

Thanks to this characteristic, it becomes possible to turn off the drive in a timely manner after turning the turntable, as well as to signal the completion of the switch from one position to another.

Other distinguishing features and advantages of the utility model clearly follow from the description below for illustration and not being restrictive, with reference to the accompanying drawings, in which:

- figure 1 schematically depicts the appearance of a cross-free crossless turnout switch in the translation position on a direct path, according to a utility model;

- figure 2 schematically depicts the appearance of a cross-free crossless switch in the position of translation on the side path, according to the utility model.

According to figures 1 and 2, the cross-free crossless turnout comprises a base 1 on which a rotary platform 3 adapted for rotations relative to the vertical axis 2 is mounted, on which two pairs of transfer rails 4 and 5 are located, forming a rotary transfer unit. The cross-free gaugeless turnout includes a drive 6 that rotates the turntable 3, stops 7 connected to the base 1, which limit the rotation of the turntable 3. The turntable 3 may have a locking means 8 adapted to limit the rotation of the stops 7.

The base 1, the rotary platform 3 and the drive 6 are made in the form of a single unit, adapted for assembly in the factory. The cross-free crossless turnout additionally comprises a control system 9 electrically connected to the drive 6. The rotary platform 3 has a rotary platform fixation means providing a junction of the rails of the rotary platform 4 and 5 and the rails adjacent to the turnout. These are the rails of the underwater path 10, the straight rails of the bypass path 11 and the side rails of the bypass path 12. The means for fixing the turntable 3 are not shown in the figures.

In general, the turntable 3 has a rotary drive 6, which may be of a liquid or mechanical or electrical nature. In figures 1 and 2 shows an option when the drive is made of electrical nature in the form of an electric motor.

The control system 9 contains limit switches 13 located on the base or on the turntable, providing the generation of an electrical signal in the extreme positions of the turntable 3. The signals propagate through wires 14, but any signal transmission channels, including wireless, can also be used in general.

Switching bezostrokovogo crossless turnout as follows:

- a control electric signal is supplied to the control system 9, electrically connected to the drive 6, for example, wires 14;

- drive 6 drives the rotary platform 3;

- when the limit switch 13 is activated after the end of the arrow switch, an electrical signal is supplied, which turns off the operation of the actuator 6 and signals that the switch is in a different position.

In accordance with the proposed utility model, the applicant made a model of a bezel-less crossless turnout switch from the details of a children's railway. As a drive, a battery-powered DC motor was used, which rotates the turntable using a gear. As the limit switches, copper contacts were used, which simply opened the circuit when turning the turntable to the required angle. The means of fixing the rails was not used, as it used the friction of the drive in the off state, ensuring the adjoining of the rails.

As a result of testing the layout, it was found that the utility model allows:

- to reliably switch a cross-free crossless switch from one position to another with an equal degree of reliability in the “woolly” and “anti-woolly” directions;

remotely switch a cross-free crossless switch;

- signal the switch of a non-fissured crossless switch from one position to another.

An additional effect of this utility model is that it:

- reduces the complexity of the manufacture of bezostrokovogo crossless switch, as it can be produced in the factory;

- This principle is also suitable for single-rail vehicles such as suspension trolleys.

Improving the reliability of the bezostroyny crossless switch will allow the widespread use of bezostrokovoy switch. At the same time, advantages have been achieved associated with the use of a cross-free crossless turnout switch over the traditional one, namely:

- less material and labor costs are required for production, much easier than analogues, expensive materials are not required (modern hands are partially made from expensive manganese steels), conventional rails are used;

- the service life is orders of magnitude higher, due to a sharp decrease in dynamics and the absence of adjacent sliding parts;

- the reliability of work increases (the problem of modern arrows is cyclically adjoining sliding parts: wits and frame rails - the junction must be constantly cleaned of dirt and snow in winter);

- there is no crosspiece, which significantly reduces the dynamics;

- operating costs are significantly reduced (currently used: air cleaning, shooter electrical heating, a large amount of manual cleaning, especially during snowfalls and dust storms);

- environmental friendliness increases (when lubricating turnouts, oil extraction is used, which, if it enters the soil, harms the environment and creates a fire hazard)

- ease of operation (especially in winter and during dust storms), due to the lack of wits, frame rails, crosses and counter rails.
