RU21383U1 - ELECTRIC DRIVE HEADSET WITH EXTERNAL SWITCH - Google Patents

Description

Electric headset for turnout with external contact.

The utility model relates to devices of railway automation and telemechanics and can be used to install an electric drive, in particular an electric drive VSP-220N on turnouts of high-speed railways.

A well-known headset of an electric drive (certificate of authorship No. 1533929 В 61 L 5/06, prior. 04/19/99) containing a coupling strip rigidly attached to rails at one end, the other ends of which are made with a protrusion having holes for adjusting unit bolts, rigidly attached to a connected strip installed outside the rail gauge by foundation squares, at one end of which an electric drive is fixed. In order to increase reliability, it is equipped with an additional connecting strip fixed inside the rail track and rigidly connected to the other ends of the foundation squares. In addition, the headset of the electric drive is equipped with a U-shaped bracket with holes rigidly bolted between the other ends of the coupling strip, between which an additional connected strip is placed with a gap.

However, this headset does not meet the requirements for the organization of turnouts for high-speed movement, as does not provide a tight and reliable fit wit to frame rails. In addition, this headset is applicable for use with the SP-6 drive.

The closest in technical essence and the achieved effect to the claimed utility model is a headset for mounting an electric drive on an arrow with a closure (copyright certificate No. 704847, В 61L 5/06, prior. 06/27/78), selected for the prototype containing foundation squares, a coupling a strip and a node for connecting the operating rod of the electric drive to the operating rod of the contactor. Moreover, the knot for connecting the working rod is equipped with a lever mounted on the tie-rod, rotatably rotatable, with which the working rod of the electric drive and contactor are pivotally connected at different distances from the center of rotation of the lever.

However, this headset cannot be used for installation on the turnout to organize high-speed movement, as This headset can only be used for installation on wooden beams using spaced foundation squares and an external contactor with a horizontal closure nrinsin that does not have adjustment when installed on the turnout switch. In addition, the design of the used SP-6 electric drive for working with an external contactor requires the use of additional devices that complicate both the design of the headset and the methods of its maintenance.

The task to which the claimed utility model is aimed is to improve the safety of railway traffic during high-speed traffic by using the new VSP-220N electric drive with a 220 mm slide and a vertical external siege, which ensures a tight fit of the wits to the frame rail.

The technical result that can be obtained using the utility model is the ability to:

-applying a reliable design for the translation of wits on turnouts during high-speed traffic in mixed cargo and passenger traffic when operating outdoors in macroclimatic regions of temperate and cold climates;

-application of a new design of electric drive type VSP-220N, designed to work together with an external contactor;

-creation of a reliable design for mounting the VSP-220N electric drive on the arrow on reinforced concrete bars without the use of foundation squares;

2, l M ///

-provision of control of the position of wits;

-providing reliable fixation of the pressed wit with the help of a ginger;

-creation of a more compact device located in one sleeper box.

The problem is solved due to the fact that the headset of the electric drive, for example, VSP-220N, with a vertical external contact, containing a short working rod, a hinge, a lever of the transfer device, adjustable control rods and a vertical external closure, is additionally equipped with a set of interchangeable joints for adjusting the drive. The control rods are made with the possibility of adjusting the length, and the transfer device is located on the drive side.

Thus, the improvement of railway safety during high-speed traffic is achieved due to new design elements of the headset, which allows for the joint operation of the electric drive and the external grinder. In addition, due to the new arrangement of structural elements, metal consumption is reduced, dimensions are reduced and headset maintenance is facilitated.

The essence of the utility model is illustrated in the drawing, which shows a schematic diagram of the design of the headset.

The headset contains:

1- electric drive, for example, VSP-220N;

2- hinge for connecting the gate of the electric drive with the working rod;

3- short draft;

4- working draft, transmitting movement from the gate to the closure;

5 - external contactor with a vertical arrangement of the clamp in relation to the leading bar;

6 - a bed with a lever for transmitting movement to another sleeper box on the interspin traction;

7- control draft short adjustable;

8- control draft long adjustable;

9- fasteners;

10- insulation elements; 11, 12 - interchangeable joints; 13-carriage.

Electric actuator headset with switch, designed to install the VSP-220N electric actuator with a 220 mm gate stroke on high-speed turnouts on reinforced concrete beams. The headset is designed for passenger train speeds of up to 350 km / h in a straight section of the track in conditions of combined cargo and passenger traffic.

The headset design was created for the joint operation of the VSP-220N electric drive with a gate stroke of 220 mm and an external contactor with a stroke of 220 mm.

The drive is mounted on a carriage 1.3, which is mounted through insulating gaskets to two reinforced concrete beams. A frame with a lever is installed between the frame rail and the drive 6. The long end of the lever through the working short rod 3 and the hinge 2 is connected to the drive gate 1 and the working rod 4, which, in turn, is connected to the external contact 5.

The drive installation is adjusted using a set of interchangeable joints 2 or 11, or 12.

At the same time, the design of the headset provides:

-transfer wits to extreme positions;

-admissible gap between the wit and the frame rail in the pressed position is not more than 3 mm;

-the ability to compensate for extreme deviations of the gauge and installation dimensions of the drive;

-fixing wags arrows to the frame rails with a vertical shift of the wits up to 6 mm and horizontal (stealing) up to 10 mm;

- translation effort of at least 6000 N;

-controlling the extreme positions of wits. The headset works as follows:

The drive gate through a hinge 2 or 11 or 12 and a short working rod 7 transfers the lever from one extreme position to another. In this case, the movement of the long shoulder of the ryaga is transmitted to the working draft 4 of the headset.

The working rod 4 is connected to the jaw of the leading plate of the external contactor 5. When the working rod 4 is moved, the leading plate of the contactor 5 begins to move, and then the clamp clips 5 together with the arrow keys. The translated arrow is securely fixed in the extreme position with a clamp due to the presence of a curly cutout in the base of the contactor 5.

The length of the control rods 7 is adjusted using threaded bushings within ± 20 mm.

A short lever arm transmits movement from the gate of the electric actuator 1 through a connecting rod with a compensator to the interspin rod in another sleeper box.
