Description

COLORLESS COLORLESS ARROW

The invention 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 rotatable drive, stops associated with the base, limiting the rotation of the rotatable otnoy platform and intended for use in branching structures

15 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 area of application of 20 bezostryovye crossless turnouts and increase the efficiency of railway track development in general.

From the copyright certificate SU 1649006 A1, E01 B 7/10, 05/15/1991, a cross-free crossless switch is known. It describes a translation that contains connecting paths, double movable rails with 25 connecting rods and a transfer mechanism, with each of the movable rails fixed at one end to a slewing ring and the other connected to the rod of the transfer mechanism.

The disadvantage of this solution is the inadequate reliability of switching the bezelless crossless switch, associated with 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 swivel adapted to rotate about a vertical axis is mounted a platform on which two pairs of transfer rails are located, forming a rotary transfer unit, a drive that rotates the rotary platform, stops associated with the base, limiting the rotation of the rotary platform. See copyright certificate SU 1567436 A1, B61 L 5/02, E01 B 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 invention.

The disadvantage of this solution is the inadequate reliability of switching a sharpless 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 invention 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 an embodiment of the invention 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 invention in which the drive is rigidly mounted on a rotary platform and kinematically connected with 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 an embodiment of the invention in which the drive is 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 an embodiment of the invention in which the drive is 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 an embodiment of the invention in which the control system comprises limit switches located on the base or on the turntable, providing for 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 invention 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 switch in the position of the transfer to a direct path, according to the invention;

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

According to figures 1 and 2, the cross-free crossless turnout contains a base 1 on which is adapted to rotations relative to the vertical axis 2, the rotary platform 3, on which there are two pairs of transfer rails 4 and 5, forming a rotary transfer unit. The cross-free gaugeless turnout includes 105 drive 6, which 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 needleless 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. 115 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 fixing means of 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 120. 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 125 3. The signals propagate through wires 14, but any signal transmission channels, including wireless, can also be used .

Switching bezostrokovogo crossless turnout as follows:

- a control electric signal is supplied to the control system 9, 130 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.

135 In accordance with the proposed invention, the applicant made a model of a bezotryovnogo crossless switch from parts children's railway. As a drive, a battery-powered DC motor was used, which rotates the turntable using a gear. As limit switches

140 used copper contacts, which simply opened the circuit when turning the turntable to the desired 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 discovered that the invention

145 allows you to:

- to reliably switch off a bezelless crossless switch from one position to another with an equal degree of

. reliability in the “coat” and “anti-wool” directions;

remotely switch off a cross-free crossless 150 turnout switch;

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

An additional effect of the present invention is that it:

- reduces the complexity of the manufacture of bezostrokovogo crossless 155 turnouts, as it can be done 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. 160 At the same time, the advantages associated with the use of a cross-free crossless turnout over the traditional, namely:

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

165 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;

- increased reliability (the problem of modern arrows - cyclically adjoining sliding parts: wits and frame rails - place

170 adjoining areas must be constantly cleaned of dirt and snow in winter); - 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 (oil lubrication of turnouts 175 uses oil extraction, 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.

180 Explaining the above description, we clarify that:

The woolly movement is the movement of a train or shunting unit in the direction from the cross to the arrow of the arrow, the anti-wool movement is the movement of the train or shunting unit in the direction from the arrow of the arrow to its cross. (Technical Railway Dictionary. - M., 1941);
