SU25965A1 - Mechanically operated electric rail pedal - Google Patents

Description

The present invention is a modification of the mechanically operating electric rail pedal according to patent No. 15849, in which the movable contact is mounted on a swivel disk, under the action of a flexible rod held by the same pull, tensioned between the rail foot and the fixed base of the device and weakened rail bend during deflection under the action of the passing wheel of the train; The proposed pedal is different from this by replacing the spring with a load and using a contact lever.

In FIG. 1 and 2 depict the pedal c. two projections, fig. 3 and 4 form of its implementation.

The base of the pedal is a cast-iron box 1, attached to the rail with pads and four bolts.

Racks 12 and 13 are fastened inside the box 1 with center screws 15 and 16 on which roller 18 can rotate with a fixed arrow 19 fixed on it. At the end of the arrow 19, the flat spring serves to create better contact and adjust the pressure in contact without deformation of the arrow itself. A shelf 5 (made of an insulating material) with a terminal 9 is attached to the wall of the box 1 on the brackets b. The contact between the spring of the arrow 19 and the contact spring 11 is normal.

or closed, or open, depending on the setting of the pedal to open or close. In the middle of the upper wall of the box 1 there is a round one: the hole into which the pressure piston 23 passes, tightly fastened to the rail with the help of the bar 30, on the plates 32 and bolts 33. screw 26.

One end of the wire 28, the other end of the co- Torah thrown over the roller 18 and attached to the load 21.

In order to avoid slippage, the wire is pressed against the roller with a wide head screw 20.

The pedal operates as follows: when the load passes over the point of attachment of the piston 23, the latter drops somewhat (due to the difference in deflections between the points of attachment of the pedal and the piston), and the screw 26 is carried along, i.e. and wire attachment point. Since the wire is tensioned by a weight 21 suspended thereto, as a result of lowering the wire anchorage point, the load is lowered, while slightly turning the roller 18 (the wire is fixed on the roller). Bonded to the roller, arrow 19 will turn to the same angle as the roller.
