Description

The utility model relates to the field of bridge building, namely to building floating railway bridges.

Despite the fact that the main method of assembling bridge ferries (Fig. 1, item 1) of a floating railway bridge is a crane assembly from a pier, in practice the method of assembling bridge ferries (Fig. 1, item 1) on the ground is also used , followed by their release into the water.

The discharge of bridge ferries (Fig. 1, item 1) is carried out along two railway tracks, either by sliding along the rails, or by rolling the pontoons with the help of rollers. To reset the bridge ferry (Fig. 1, item 1), it is necessary to create a traction force towards the reservoir.

When used as a base for a railway track on reinforced concrete sleepers (Fig. 1, item 2), the traction force must be created towards the reservoir, but the device that creates the force should not interfere with the free descent of bridge ferries (Fig. 1, item 1) onto the water.

The technical result is the exclusion of the obstacle of the traction device in the way of dumping bridge ferries (Fig. 1, item 1) by changing the direction of the traction force away from the railway track.

To achieve a technical result, it is required to assemble a gripping device, consisting of a mount (Fig. 1, pos. 1), which is installed on a reinforced concrete sleeper (Fig. 1, pos. 2) with drilled holes for clamps installed on the input mount (Fig. 2 , pos. 5) and exit rollers (Fig. 2, pos. 6) in the plane so that the traction cable (Fig. 1, pos. 7) changes direction in the required direction, and clamps (Fig. 2, pos. 4) .

The essence of the utility model is illustrated by drawings.

The figure 1 shows a view of the device from the side of the sleeper. This view shows the mounting location of the proposed device and the angles of the rollers.

Figure 1 shows:

pos. 1 - bridge ferry;

pos. 2 - reinforced concrete sleeper;

pos. 3 - mount;

pos. 7 - traction cable.

The figure 2 shows a view of the device from the end of the sleeper. This view shows the fastening of the proposed device with the help of a latch and the order of rope reeving.

Figure 2 shows:

pos. 4 - latch;

pos. 5 - input roller;

pos. 6 - output roller.

The utility model is implemented as follows.

To achieve the technical result, a mount is made (Fig. 1, pos. 3) with attached two input (Fig. 2, pos. 5) and output rollers (Fig. 2, pos. 6) and drilled holes for the clamps (Fig. 2, item 4).

The mount (Fig. 1, pos. 3) is installed on the reinforced concrete sleeper closest to the reservoir (Fig. 1, pos. 2) and fixed on it with the help of clamps (Fig. 2, pos. 4). Through the input (Fig. 2, item 5) and output rollers (Fig. 2, item 6) pull the traction cable (Fig. 1, item 7).

Thus, when installing the above device, the traction device can be installed away from the path of descent of the bridge ferries (Fig. 1, item 1), which makes it possible to exclude its engagement with the bottom of the bridge ferries.
