SU1257044A1 - Device for levelling and compacting loose material surface in gondola cars - Google Patents

Description

The invention relates to the mechanization of compacting bulk cargo and forming its surface when loading railway gondola cars, in particular, coal, coke, peat and other lightweight goods.

The purpose of the invention is to reduce the loss of bulk cargo.

Fig, 1 shows the proposed device, in Fig.2 - section aa in Fig.1.

The device contains a lift-lowering mechanism mounted on -rame 1 with portal 2 in the form of carriage 3 with drive 4, on which guide bushings 5 are fixed and drive 6 of raising and lowering plate 7 with vibration exciters 8 and direction of springs 9. In addition, on the railroad track, to frame 1, contact locks 10 and 11 and end contact switch 12 are connected electrically with drives 4 and 6.

The device works as follows.

Gondola cars for loading are supplied and when loaded with a dry load, for example, coal, they are moved by a shunting device (not shown).

-vl-x

As the shunting device loads and moves with the shunting device, the contact switch 10 reaches and, when driven, the shunting device is turned off, and the gondola stops at the plate 7, the drive 6 is simultaneously turned on, and the plate 7 lowers onto the surface of the coal loaded into the gondola car. Simultaneously with the lowering of the plate 7, vibration exciters 8 are turned on, and upon vibration exposure plate 7 compresses the load and forms its surface in the gondola car. After the slab is lowered onto the cargo surface, the shunting device and the drive 4 of the trolley 3 are simultaneously turned on, and the gondola moves synchronously with the plate 7 and the trolley 3 along the frame 1 of the gantry 2 until the trolley 3 hits the contact switch 11, and when the trolley 3 hits the drive 6 and 4, and the plate 7 rises to the upper position, and the carriage 3 returns to its original initial position and stops when it hits the final contact switch 12, by means of which the drive 4 of the carriage 3 is turned off. When loading and moving the next gondola and hitting it on the contact switch 10, the device operation cycle will be repeated in the same order.

Claims (2)

1. A DEVICE FOR LEVELING AND SEALING THE SURFACE OF BULK CARGO IN GONDS-CARS, containing a port with vertical movement through the mechanism of movement by a plate for compressing cargo and vibration exciter, characterized in that, in order to reduce the loss of bulk cargo, the working surface of the plate is formed from joined curved sections, the transverse and longitudinal sections of which are described by the expressions = tog _a (1 + x), respectively .0 έ x £ .1 Y _r = tog _a [(1 + 1) - x] for - | ίχ where t is the width or length of the gondola; a - the base of the logarithm, while a = s-b - for cross sections; a = 6-11 - for longitudinal sections. 2. Device pop. 1, characterized in that the mechanism for moving the plate is mounted with the possibility of movement in a horizontal longitudinal plane, made in the form. a drive trolley mounted on the portal frame and is equipped with contact switches that are mounted on the portal frame and are electrically connected to the drive of the trolley. tpaeJ
