The L-shaped clamps 15 and 16 mounted on the racks 3 and 4 and pressed by nuts 6 are in contact with their own shelves with the edges of the rim 19 of the track roller 20, and the lower ones with the edges of the track 5. Thus, the roller is fixed relative to the track. 4 il.

The invention relates to a transport engineering, in particular, to devices for mounting tracked vehicles on railway platforms.

A device for securing loads on a vehicle platform is known, comprising a base plate with spikes for interacting with the platform and the fastening elements of the cargo being carried with the base plate.

The disadvantage of this device is the great complexity of mounting tracked vehicles.

The closest technical solution to the present invention is a device for mounting tracked vehicles on a vehicle platform, comprising a plate, on one surface of which there are pins for interacting with the vehicle platform, and on the other, racks capable of entering into the holes of the attached machine .

However, the known device does not provide sufficient reliability of mounting the track-borne vehicle on the platform, since under the influence of longitudinal dynamic loads that occur when the platform is decelerated, for example, during the formation of a train, the brake bands of the track-type machine can slip and move it forward or backward for a certain distance. along the fixed lower branch of the caterpillars.

The purpose of the invention is to increase the reliability of mounting tracked vehicles on the platform.

This goal is achieved by the fact that the proposed device comprising a plate, on one surface of which there are pins for interacting with the vehicle platform, and on the other racks made with the possibility of entering crawlers of the fixed machine through the holes, is equipped with L-shaped clamps on racks a shelf of each of which is located above the track link of the machine for interacting with its free end with the rim of the track roller, and the lower end of the vertical section of the clamp is placed on the track.

With this device, the rollers are rigidly fixed to a slab attached to the platform, which prevents the rollers from moving along the track and thus improves the reliability of the track on the platform.

Figure 1 shows a device for mounting, a slit; figure 2 - view And figure 1;

on fig.Z - section bb in figure 2; figure 4 - section bb In figure 2.

The proposed device contains a plate 1, on the one hand of which the pins 2 are welded, and on the other, the pillars 3 and 4 are fixed, which are installed in the holes of the links of the caterpillar 5. At the ends of the pillars 3 and 4, a thread is made on which the nuts 6 are mounted. performed in conjunction with the bracket 7, to which

using the finger 8 and the pin 9, the removable lever 10 is fixedly attached. At the lower end of the lever 10 there is a vertical hole, where is the screw 11c with the lock nut 12, which interacts with the lower

the plane of the edge of the platform 13. At the top, the ends of the pillars 3 and 4 are installed using washers 14 and nuts 6 L-shaped clamps 15 and 16. The shelf of each of the clamps 15 and 16 is located above the link of the caterpillar 5 and interacts with its free end with the edge of the protective rings 17 and 18, respectively, which are part of the rim 19 of the track roller 20. The lower end of the vertical section of each of the clamps 15 and 16 is placed

on track 5. The holes 21 in the clamps 15 and 16, where the pillars 3 and 4 are included, are made oval, which ensures a more reliable contact of the clamps and the edges of the rim 19 when the roller 20 is displaced relative to the plate 1.

Securing tracked vehicles on

The platform is implemented by four devices as follows.

The tracked vehicle drives onto platform 13 and is installed symmetrically with its

longitudinal axis. The links of both caterpillars located under the front and second to last support rollers are marked with marks (two links are marked on each caterpillar). After that, the tracked vehicle drives back so that the marked links of the tracks, which were under the front rollers,

found themselves on the inclined section of the caterpillar branch in front of the rollers, after which devices for fastening machines without detachable arms 10 are attached to the marked links. To do this, stands 3 and 4 are mounted in the holes of the marked links, and L-shaped mounts are mounted on the upper ends of which through oval holes 21 clamps 15 and 16, moreover, they are turned 180 ° relative to the working position shown in Fig. 1 (the free ends of the shelves of the L-shaped clamps are oriented towards the edges of the track, and the lower ends of the vertical sections of the clamps are scheny on caterpillar). With the help of washers 14 and nuts 6 clamps 15 and 16 in this position is fixed.

After installing the devices on the front tracks, the machine drives forward so that the rear tagged track links are on the rear inclined track sections. The tagged rear link of the track is mounted in a similar way to the front link of a single device and the machine returns to its original position.

The devices are installed under the front and next-to-last rollers so that the machine can perform 2-3 back-and-forth movements for better insertion of the pins 2 into the platform 13. After installing the machine to its original position, when the front and pre-second rollers are installed on the links attached to them devices, to each of the 4 brackets 7 using the finger 8 and the pin 8 is attached removable lever 10, and

the screw 11 is tightened until it is firmly fixed to the lower plane of the edge of the platform 13 and secured with a lock nut 12. After that, nuts 6 are turned off, clamps 15 and 16 are turned 180 ° into working position (the shelf of each of the clamps interacts with its rim 19 of the support roller 20 , and the lower ends of the vertical sections of the clamps are placed on

caterpillar) and tighten the nuts 6 finally. At the same time, the oval holes 21 ensure reliable contact of the ends of the flanges of the clamps 15 and 16 with the rim 19 in the case of displacement of the support roller 20 relative to

plates 1.

The use of L-clamps 15 and 16 in the proposed device ensures the fixing of the support roller 20 relative to the fixed link of the track 5, which prevents the roller from moving along the track when the machine is subjected to longitudinal dynamic loads and increases the reliability of mounting the track machine on the platform.
