Abstract

This invention relates to devices for compacting railway ballast. The purpose of the invention is to improve the quality of the ballast compaction. The tamping machine comprises a frame 1 mounted on it with the ability to move in a vertical plane by a hydraulic cylinder 2 a tamping unit consisting of holders 3, on which are mounted rotatably around the axes 4 of the liner 5. The vibrodrive 7 with an eccentric shaft is placed on the upper end of one of the strips 5. The tamping 5 is interconnected by a hydraulic cylinder 9 of their supply, hinged at the upper ends of the tampers 5. The centering element is a hydraulic cylinder 10 hinged to the holder 3 and an eccentric Rikov shaft having three knee, the first of which is pivotally connected to the upper end podboyki 5, a second - a hydraulic cylinder 10, and the third - a cylinder 9. The cylinders 9 and 10 have different working volumes of the piston rod and cavities. The corresponding cavity of the hydraulic cylinders 9 and 10 are connected in parallel by pipelines. 2 Il.

Lazy hydraulic cylinders 9 and 10. The cavities of the hydraulic cylinders 9 and 10 are connected by pipelines in parallel with each other.

Such a connection of the cavities of the hydraulic cylinders 9 and 10 allows self-alignment of the pads 5 when their working parts approach each other by simultaneously applying pressure to the cavities of the hydraulic cylinders 9 and 10 and balancing the forces on the pads at their different working stroke. This achieves an asynchronous way of working

The tamping machine operates as follows.

Initially, the vibrodrive 7 is turned on, and the eccentric shaft 8 begins to rotate. Since the cavities of the hydraulic cylinders 9 and 10 are locked, the brakes 5 operate in a synchronous manner. Tee, each breakdown vibrates regardless of the resistance forces,. Acting on them, this achieves a reduction in the depth of penetration of the pallets 5, by the Hydraulic cylinder 2 the holder 3 is lowered along the guides 14 until the pads 5 fall to the working depth. Then, the working parts of podboek 5 begin to approach the hydraulic cylinder 9 of the feed and the hydraulic cylinder 10, in the cavities of which the hydraulic fluid is supplied simultaneously, since their cavities are interconnected by pipelines. The hydraulic cylinders 9 and 10, at the end positions of the hydraulic cylinder rods and locked feed lines, operate as two rigid rods. When fed to one of the pressure lines and connected to the other line with a hydroaccumulator or with a drain, these hydraulic cylinders function as one rigid rod. In the presence of two rigid rods, the machine operates in a synchronous pattern (during the deepening of the pods, when necessary with smaller
