SU1207866A1 - Device for transverse displacement of load-carrying frame with lowered cargo platform of railway vehicle - Google Patents

Description

The invention relates to railway transport and is intended for lateral movement of a cargo-bearing frame of a railway vehicle with a reduced cargo area when passing through tunnels and bridges, as well as for reducing the output of the load-carrying frame with a cargo that is not dimensionally wide inside the curvilinear track. The purpose of the invention is to increase reliability and improve performance.

FIG. 1 shows the layout of the device on a rail vehicle; FIG. 2 is a view along arrow A in FIG. one; in fig. view along arrow B in FIG. 1 (worm gear with telescopic pivot pin).

The end frame 1 of a rail vehicle with a lowered load platform is located under the load-carrying frame 2, which at its ends through the swing carts 3 rests on the end frame.

On each end frame 1 there is a worm gear 4, consisting of a single screw 5 with a handle 6, a worm gear 7 located horizontally, the center of rotation of which is rigidly fixed to the gear case 8. .2

Arm frame 1. A telescopic pin 9 is rigidly fixed at a worm gear 7 at a certain distance from the center of rotation. A groove 10, located along the crescent shaped curve, is made on the crest of the worm gearbox to rotate the worm gear. On the load-carrying frame 10, a longitudinal groove 11 is made for engagement with the telescopic pivot 9.

The device works as follows.

For lateral movement of the load carrying frame, it is necessary to lift the telescopic pin 9 upward to engage the walls.

the longitudinal groove 11 of the carrying frame.

When rotating the handle 6 connected to the screw 5, the torque is transmitted to the worm gear 7, which, turning at a certain angle, turns the telescopic king pin 9. The telescopic pin 9, located in the longitudinal groove 11 of the load-carrying frame 2, moves the latter in the transverse direction by the required value corresponding to a certain angle of rotation of the worm gear 7.
