Description

The invention relates to railway transport, in particular, to devices for changing switches.

The aim of the invention is to ensure the safety of transportation by changing the position of the switches within the dimensions.

Fig. 1 shows a general view of a device for changing turnouts; Fig. 2 shows a device for changing switches in the transport state; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 1; Fig. 5 shows a section B-B in Fig. 1 (transport state).

The device for changing turnouts consists of two four-axle platforms 1 and 2 with sides (FIG. 1) equipped

platform crane trusses 3 and 4, mounted between them by means of hinges of the truss truss 5, which also has guides that extend the crane runway of the platform trusses to move the cantilever crane 6 along them.

The support flank 7 of the platform 2 (Fig. 4) is pivoted in a transverse vertical plane and opens outwards.

The hinge 8 is installed at the base of the supporting side with the possibility of rotation n 10-15 °.

When the angle of inclination of the boards is less than 10 ° npi / loading and unloading, pulling devices are required, the stability of the block

when placing them on platforms and require their additional consolidation.

At an angle of more than 15 °, the lateral dimension of the approach of buildings C is broken.

On both platforms below the floor level there are niches 9 (Fig. 3) and 10 (Fig. 4), open from the adjacent ends of the platforms and offset relative to the longitudinal axis towards the tilting side 7 (Fig. 4) to enable loading and unloading of blocks. switches within height limits.

The location of the niche on the hinge side provides the gauge of the switch during transport. In addition, it is impossible to make a niche along the longitudinal axis or to shift to the tap, because it is not possible to break the ridge beams.

 The side walls 11 and 12 of the niches are inclined in the direction of loading and unloading at an angle equal to the angle of rotation of the supporting side.

In platform 1, parallelism is achieved with a rigid bead due to the presence of guide pillars rigidly attached to the inner surface of the bead under the glom, equal to the angle of installation of the niche bead.

To the place of change of switches, the device should be in the transport state: on platform 1 there is a console crane 6, on platform 2 - a flying truss blocks of a switch.

At the work site, the flying truss 5 is installed in the working position between platforms 1 and 2 after they are uncoupled and the truss 5 is pivotally connected to the trusses 3 and 4 of both platforms.

The cantilever crane 6 is moved along guides to the span farm 5,

When changing the switch from the direction of the switch, it is necessary to reload the blocks of the new switch from platform 2 to platform 1 before starting the work so that frame unit 13 is close to crane 6, and the spider block is located in niche 9 of platform 1. For this support board 7 platform 2 with a hinge installed at the base, tilted out 15 ° outwards in a transverse vertical plane, the blocks attached to platform 2 release and using the cantilever crane 6 transfer the blocks to platform 1.

The device is installed so that

span farm 5 was above the removable unit. The first block of the old turnout is stitched, lifted, turned into a tilted position, moved by crane 6 to the loading place on the tilted supporting side 7 of platform 2. After that, the crane is moved along the crane runway to platform 1 to capture the new translation unit and lay it on the way

place of old

After the first block has been laid down, the device is moved to change the next block. In this way, all three switch units are changed.

When changing the cross block 14, it is moved to the loading place so that it passes along the tire 10, open from the side, adjacent platform 2, located below the floor level beyond the longitudinal

an axis on the hinge side at the base of the board where the unit is installed, as a result of which it constantly remains no higher than the upper dimension 1-T.
