Description

The utility model relates to auxiliary devices of railway trains and can be used to place additional equipment on free connectors of an automatic coupler of the SA-3 type and compatible structures.

When operating railway rolling stock and railbed, in some cases it becomes necessary to use additional equipment, for example, light signaling devices, tracking devices, devices for non-contact measurement of track parameters, as well as devices for treating the track with chemical reagents, for example, herbicides. As a rule, for the installation of such devices, special fasteners are used, which are used on special-purpose cars. When used, these cars must be located in a certain place of the train, for example, at the beginning or end of the train (see, for example, the materials of the electronic resource: URL: https://lokomo.ru/zheleznodorozhnyy-put/borba-s-rastitelnostyu-na -puti-2.html - Electronic text, accessed 06/24/2022).

To solve the problem of installing auxiliary equipment, the closest to the claimed device for installing a tool bag (Australian patent application AU2009202533) is known from the existing prior art, which can be used in conjunction with a car coupler. The specified device can be installed on the vehicle hitch bracket with a base plate for attaching to the hitch. When installing and removing the device, disassembly of the coupler is required, which significantly limits its scope.

The objective of this utility model is to expand the arsenal of means to ensure the installation, storage and use of additional elements of the rolling stock, which can be used both during the movement of the train and in parking lots.

The technical result of the claimed utility model is the use of a universal device for installing auxiliary equipment that does not require alteration or modernization of rolling stock elements when used.

In addition, the utility model, in comparison with the prior art, during installation and use, does not require changes in the design of the rolling stock or its elements.

The specified technical result is achieved due to the fact that the housing for installing attachments on the CA-3 automatic coupler is made containing a vertical part, lower and upper end parts, while the vertical part is made in the form of a thin-walled profile of constant cross-section, the outer surface of the rear wall of which repeats contours of the mouth of the coupler body and is conjugated with the rear surfaces of the side walls, which, at least partially, repeat the outer contours of the outer surfaces of the large and small teeth of the coupler body and are conjugated with the front surfaces of the side walls located beyond the contours of the surface of the coupler body and mated with the surface of the front wall, while the lower end part is fixed on the lower part of the body within the boundary of the body contour for the installation of automatic coupling equipment, and the upper end part completely covers the upper end of the vertical part and serves as a stop rum, limiting the vertical movement of the body for installing attachments in the mouth of the body of the coupler. In a particular case, the implementation of the plane of the front surfaces of the side walls are directed along the axis of the automatic coupler, the device may contain a handle fixed on the outer surface of the end part. In another particular case of implementation, the housing is configured to install a video camera, while the front wall of the housing contains a hole for the camera lens.

The essence of the utility model is illustrated by drawings, which show:

In FIG. 1—connector of automatic coupler CA-3;

In FIG. 2 - isometric view of the body assembly;

In FIG. 3 - image of the body, bottom view.

The SA-3 automatic coupler, in conjunction with which the proposed device is used, is a standardized automatic coupler used in the railway transport of Russia, in the republics of the former USSR and in Mongolia for coupling rolling stock units with minimal participation of the coupler.

The automatic coupler consists of the following parts: the body (connector) of the automatic coupler and the mechanism located in it, the traction device with the absorbing device (springs), the uncoupling drive and the impact-centering device. The body of the automatic coupler is a hollow steel casting, in the head part of which the details of the mechanism are placed. If you look at the automatic coupler from the front, then it has a large tooth on the right, and a small one on the left. The void between the teeth is called the gap of the coupler. On the left, a lock protrudes from the pharynx, in the middle there is a paw of the lock holder.

As shown in FIG. 1, The CA-3 coupler is a non-rigid type pull hitch. It consists of a body 4 and parts of the clutch mechanism: lock 5, lock holder 2, fuse 3, lift 6, lift roller 7.

The head part of the automatic coupler (head) passes into an elongated hollow shank, in which there is a hole 1 for placing a wedge connecting the automatic coupler with a traction collar. The coupler head has a large 10 tooth and a small 9 tooth. In the space between the small and large teeth, in the so-called mouth of the automatic coupler, the lock 5 and the lock holder 2 protrude, interacting in the coupled state with the adjacent automatic coupler.

The large tooth has three reinforcing ribs: upper, middle and lower, smoothly turning into the shank and interconnected by a bridge. The head of the automatic coupler ends at the back with a stop 8, designed to transfer, in case of an unfavorable combination of tolerances of a hard impact, to the center beam through the end beam of the car frame and the impact socket.

It is important that the shape of the mouth of the body of the CA 3 automatic coupler and other mating elements of the body is standardized and significant deviations in size are not allowed. Another important feature of automatic couplers is the possibility of withdrawing the lock and lock holder inside the body flush with the surfaces of the body, when the lock and lock holder are removed from the mouth of the automatic coupler body. In this mode, it becomes possible to install the body of the utility model device on the body of the automatic coupler, ensuring reliable fixation.

As shown in FIG. 2, the housing for mounting attachments on the CA-3 automatic coupler is made containing a vertical part 200, as well as those shown in FIG. 3 lower 301 and upper 202 end parts, while the vertical part is made in the form of a thin-walled profile of constant cross-section, the outer surface of the rear wall 302 (Fig. 3), which repeats the contours of the mouth of the coupler connector housing, and is conjugated with the rear surfaces of the side walls 303 and 304, which, at least in part, repeat the outer contours of the outer surfaces of the large (surface 303) and small (surface 304) teeth of the coupler body connector and are mated with the front surfaces 204 and 306 of the side walls located outside the boundaries of the contours of the coupler body surface and mating with the surface of the front wall 203, while the lower end part 308 is fixed on the lower part of the body within the boundary of the body contour for installing automatic coupler equipment, and the upper end part 202 completely covers the upper end of the vertical part and serves as a stop limiting the vertical movement of the body, for installing a hinged appar ature in the mouth of the body of the coupler. In a particular case of implementation, the planes of the front surfaces of the side walls are directed along the axis of the coupler, the device may contain a handle 210 fixed on the outer surface of the end part. In another particular case of implementation, the housing is configured to install a video camera, while the front wall of the housing contains a hole 220 for the camera lens. The front wall can be made removable and fixed on the device using screw elements 230. If necessary, mounting supports can be installed inside the device case.

When using the utility model, the rear part of the housing for mounting attachments with devices located in it and, if necessary, on it, is installed in the mouth of the coupling housing of the automatic coupler located in the head or tail part of the train. Further, the device is used in accordance with the purpose of the equipment installed in it. If necessary, the specified equipment can be implemented in a stand-alone version, or energy can be supplied from pneumatic lines or electric circuits of the train.
