The invention relates to devices for securing rail vehicles that perform reciprocating with numerous stops at precisely designated places, for example, to provide reliable joining of sections of paths of a bridge chassis mounted on a transport trolley with chassis tracks installed in sections of a block greenhouses when transporting said chassis to adjacent sections of the greenhouse ./. ..-...

BACKGROUND OF THE INVENTION Trolley locking devices / fixed to a rail base in a trolley stopping zone and comprising a lift drive kinematically coupled to a pivotally rotatable stop for interacting with adjacent trolley wheels at the level of wheel centers, or at the level of the contact line of the trolley wheels with the rail surface, are known.

However, these devices do not provide the required accuracy of stopping the trolley by the size of the gap between the stop and adjacent wheels of the trolley, and during operation, when the stop is worn, this gap increases; material and capacity, especially with a long base of those beds and a large number of stops; inconvenient for use, since for the trolley to lock, the operator servicing the trolley is forced to leave the operator’s position on the trolley to turn off the power cylinder of the device stop drive located outside the trolley.

A device for locking a rail means is also known, comprising a CASE, mounted on a vehicle, in which vertical wedges are mounted with a possibility of vertical movement and are connected with the drive to bring them out of contact with a stop which is mounted in the vehicle path moreover, the wedges are installed with the possibility of independent movement relative to each other and spaced apart from each other by a distance exceeding the size of the stop.

This device does not provide the required accuracy of stopping the vehicle, which is determined by the difference in distance between the wedges and the diameter of the stop.

It requires great effort to lift the wedges by moving them in the rails, to overcome which a hydraulic cylinder is required, which necessitates the installation of a hydraulic pump with a drive, and, consequently, increases the material consumption.

The aim of the invention is to increase the efficiency of the device.

This goal is achieved in that in the device for fixing the vehicle, comprising a housing fixed thereto with spring-loaded locking elements for interacting with

0 track stop, and power drive, locking elements are installed in the housing on a common axis of swing and are made with curved surfaces to cover the jamming roller and track stop,

5 sides located respectively above and below the swing axis of the locking elements and with bevels with opposite curved surfaces of the side for contact with stops fixed on the housing, and

0 links are wedged with the axis. the first roller, which is connected by a lever mechanism with a power drive and a housing. . The drive control system includes a ring covering the swing axis of the fixing elements mounted in the vertical guides of the housing with the possibility of interaction with the upper part of the track stop and with a limit switch included in the control circuit of the power drive, the difference between the diameters of the ring and axis being equal to or greater lifting heights of the ring when interacting with the emphasis.

0 dash dot-dash - in the unlocked position); in Fig.3 - section aa in Fig.2. -...

 The vehicle consists of a frame 1, on which a leading 2 and

5 driven 3 shafts on which the running wheels 4 are mounted.

A drive with an engine 5, a device for fixing 6 with an electromagnet 7, as well as segments of the chassis 8 are fixed on the frame

0 and 9. The vehicle moves along the rails 10, on the supports of which it is fixed. Way lugs 11.

The device for fixing the vehicle (FIGS. 2 and 3) consists of two locking elements 13 and 14 mounted in the housing 12, mounted on a common swing axis 15, pivotally connected with links 16 and 17 mounted on a common axis 18, on which, in addition to the indicated links. jamming roller 19 is installed,

a link 20, pivotally connected to the housing 12, and one shoulder of a spring-loaded double lever 21 with a groove 22, the second shoulder of which is connected to the electromagnet 7 by a system of links and levers 23, 24, 25.

A limit switch 26 and a guide 27 are fixed on the housing 12, in which a ring 28 is freely mounted on the axis 15, with the possibility of interaction with the upper part of the track stop 11 and with the limit switch 26 included in the power drive control circuit, the stops 29 and 0 and the spring 31 connected to the lever 21.

The locking elements 13 and 14 are assembled on the common swing axis with curved surfaces facing each other and at the moment of fixation they form catchers covering the track stop 11 below, and the jamming roller 19 above, and the surfaces of the bevels of these elements interact with the stops 29 and 30 installed in case 12.

A device for fixing a rail vehicle operates as follows.

When turning on the vehicle’s travel, the operator presses the button corresponding to the selected direction of movement located on the control panel and holds it pressed until ring 28 releases the microswitch 26. When the button is pressed, the vehicle’s drive motor is switched on and an electromagnet whose core is retracted, and its movement through the link 24, 23, 25, 21 is transmitted to the axis 18, to which the jamming roller 19 and the link 16 and 17 connected to the locking elements 13 and 14 are connected. and axis 17 up locking elements 13 and 14 are pivoted on a common axis 15 so that the lower edges of the locking elements are disposed above the track 11 and the abutment do not interfere with the movement of the vehicle. The position of the links in the released state is shown by dash-dotted lines in Fig. 2. When the vehicle is moving, the electromagnet is constantly on, therefore, the locking elements are kept in a diluted state.

When approaching the track stop 11, the ring 28 enters into interaction with it,

moves up, presses the lever of the microswitch 26 and disables the motor drive and the electromagnet 7. Under the action of the spring 31, the lever 21 together with the jamming rollers 19 and the links 16 and 17 falls down, the locking elements rotate around the swing axis 15 and are supported by bevels 29 and 30, the jamming roller enters from above between the curved surfaces of the rest of the locking elements jamming them, which lower curved surfaces cover the cylindrical surface of the track stop, reliably fixing the transport

5 means. , .....; ..

This technical solution provides a simple and reliable fixation of the vehicle on the track, reduces material consumption.
