SU111984A1 - The device for the acceleration of gaps rail track - Google Patents

Description

M3o6peteHHe relates to rail track accelerators equipped with two hydraulic jacks, the rods and cylinders of which are articulated with clips of wedge clamps, interacting with their wedges with the side surface of the rail head, and two hand-operated pumps.

Known similar devices have significant drawbacks: when one of the pumps fails, the device becomes inoperative; a bending moment occurs on the expansion rod, causing the devices to jam on the rails; fixing devices reliably on worn-out rails is not possible.

The described device is free of these disadvantages. In order to ensure the operation of the device when one of the hand pumps fails, the working cavities of the cylinders of the jacks are interconnected by a constant pipeline that communicates with both tanks for the working fluid through a shut-off valve common to both jacks.

In order to increase the reliability of fixing the device on the rails, the wedges of the clamp are equipped with self-aligning inserts that interact with the heads of the various rails.

To eliminate the bending moments on the jacks' brushes and the ends of the races being accelerated, causing the clamps to jam, the axes of the hydraulic cylinders of the jacks and the clamps are located in the same plane.

FIG. 1 is a schematic diagram of the proposed device, top view; in fig. 2 is a section along AA in FIG. one.

Two hydraulic jacks each with their brush /, / o, are articulated with a clip of wedge clamps 2, and cylinders 3, beyond jacks - with a clip (on the left in the drawing) of wedge clamps 4. K iii ;; i M wedge clamps are equipped with self-aligning inserts 6 7, interacting with railheads.

Axes of hydraulic cylinders 3, For jacks and wedges “Nfo 111984

MOB 2, 4 are located in the same horizontal plane, which eliminates 1 bending moments on the jacks' rods and the ends of the rails being accelerated.

Fluid is supplied to the cylinders from reservoirs 8, 8a using pumps 9, 10 with a manual drive through a common check valve // with a control knob 12. At the same time, fluid enters the cylinders through channels 13, 13a, and drills 14 and 15 in the stop valve. valve //, as well as through channel 16 and pipeline 17. With the help of the latter, the working cavities of both cylinders are interconnected. Therefore, when one of the pumps breaks down, the device can work with the help of another pump.

Through the use of self-aligning inserts 6, 7, the device can be securely mounted on rails with a worn head.
