Abstract

This invention relates to railway transport. The purpose of the invention is to simplify the design and increase reliability. The device contains a frame 1 mounted on a running rail parallel to the track tracks and connected to the ground. An additional gripping elements 3 for gripping the car are also installed on this frame. To ensure efficient and safe operation of the device in an easy way and to ensure insensitivity to the previous year and other conditions, the running rail parallel to the track tracks is installed outside the track track so that the space between the track track pair always remains free. In addition, the gripping elements 3 are moved from the retracted free position to the gripping and locking position for gripping the trolley solely with the aid of the pulling force applied to the cable. 1 hp f-ly, 6 ill. in (o

This invention relates to the field of railway transport.

The purpose of the invention is to simplify the design and increase reliability. Fig, 1 is given a device, obkry view, side view; in fig. 2 shows the device in FIG. 1, view Cepxyj in FIG. 3, the relative position of the track and the device; in fig. 4 - structural details of the device; in fig. 5 is a device in the movement system, top view; fig 6 is the same, option.

The device comprises a frame 1 connected to a pulling cable 2. The gripping elements 3 are mounted on the frame, with which the trolleys of the railway car are seized from below so as to displace the car to the desired location. The frame 1 (Fig. 1) is connected to the cable 2 by means of fixing and adjusting sliders 4. In addition, the fixture 5 (figure 5) for cleaning the rails is designed to maintain cleanliness of the running rail 6 in the device, the Frame 1 is installed movably on the running rail 6 with the help of the rollers 7 (FIG. 4). In addition, in Fig. 4, the plastic sliding element 8 and the spring device 9 are installed so as to move the gripping elements.

In the proposed device, a running rail 6 is installed outside the track rails so that the space between the rails remains free (Fig. 3). In addition, the gripping elements 3 are mounted so as to move from the allocated free position to the gripping and fixing position (FIG. 1) to grip the trolley using the tension applied to the cable 2.

The gripping elements 3 are made in the form of two brackets installed. symmetrical and exciting trolley bottom. This gripping point is highly advisable since in practice the trolley is the most rigid attachment point.

Due to the symmetry of the design, one of the brackets always acts as a pulling brace, and the other, respectively, as a locking or locking brace, depending on the direction of application of the force.

t gi to the car. In this connection, a high degree of safety of work is ensured, since the operation of the pull and lock brackets is always guaranteed. FIG. 1-4, the brackets are made in the form of lever elements articulated on frame 1, the ends of the cable 2 are connected to one ends of the lever elements. The frame 1 is connected to the cable 2 by means of fixing and adjusting sliders 4. However, nothing prevents this construction from being made without sliders 4, in this case, for example, the end of the pulling wire (right edge, fig. 1) is attached directly to the end of the left bracket ( Fig. 1). The fastening and adjusting sliders are of great practical importance, since with their help it is possible, for example, to fine-tune the position and replace the entire device in a very simple way.

The device works as follows.

Moving the clips (Fig. 4) takes place with the help of the tension applied to the connecting cable 2, for example, made in the form of an endless loop: when the cable pulls, the brackets rise to the gripping position, and when the wire weakens, they lower in allotted free position. The movement of the staples into the retracted free position is ensured by a simple spring device 9, which simultaneously makes the upper noBepxHoc Vb frame very even.

The device can be easily displaced along the running rail 6 to any desired position using a remote control and, moreover, using the latter, a predetermined pulling force is applied to the cable 2, so that the gripping elements 3 grip the cart and fix it so that it cannot make free movement in any direction. In this connection, the displacement of the device to the desired position under the movable car should not be absolutely accurate, since the interaction will always take place in the appropriate place when the device is shifted. As a result, for example, one of the brackets may initially be, for example, under the springs carts (.fig .1). When the device is pulled to the right, the right clip cannot be lifted until the situation shown in FIG. 1, as a result of which, at the same time, the left bracket will stop the movement of the device to the right and the interaction will occur in the correct way. In practical use, the indicated mode is very expedient, since erroneous interaction and fixation are completely excluded. The car detachment takes place while weakening the thrust force on the pulling wire, as a result of which the gripping elements 3 are turned to the allotted free position and the proposed device can be shifted to some other position if necessary. The performance of the device is also improved due to the fact that the gripping elements 3 remain in the grip position of the trolley with greater reliability, a greater thrust or braking force is applied to them

The device can be used, for example, in the central repair shop of railway cars or in the corresponding section.

FIG. 5, equipment is given that can be used in remote control mode on two paths alternately. The equipment consists of a tether installation 11 placed between a pair of rails 10 and wire tension reels 12. In this case, the cable 2 is mounted so as to move with the help of guide rollers (Fig. 5). Frame 1 is mounted to move around paths as described. Pa figs. 5 shows only four frames 1, but more can be used.

One after another, for example, each car of the train can be captured simultaneously. In addition, the equipment includes a hydraulic unit 13, used as a power source.

FIG. 6 shows a device in which a separate brake mechanism 14 is applied, the latter also functioning as a rewinding mechanism. The principle of operation of the construction of FIG. 6 is generally similar to the principle of operation of the equipment of FIG. five.
