Abstract

The invention relates to mine construction, in particular to devices for tamping sleepers during the construction or repair of a rail track in cramped conditions. Pel invention - simplified design with ease of maintenance. The pinning device consists of a trolley 1 on a rail track, on which a U-shaped guide 6 is fixed, inside it there is a power cylinder 3, the stem 4 of which drives the slide 5, which covers the guide 6. On the slide 5 there are fixed tamping blocks 26 using a hinged-lever system and rail clamps, the lower ends of which are simultaneously attached to the trolley 1. The design of the device allows using a single power cylinder to lift - lower the tamping blocks 26 and capture the rails and using a hinged-lever system to fasten the tamping blocks 26, the process of tamping the sleepers with the simultaneous introduction of the tamping blocks 26 and compressing the ballast radially to the sleeper. 4 il.

The invention relates to mine construction, in particular to devices for tamping sleepers during the construction or repair of a rail track in cramped conditions.

The purpose of the invention is to simplify the design while improving ease of maintenance.

Figure 1 shows a tamping device, general view; figure 2 - tamper; figure 3 - rail capture in the closed position; figure 4 - the same, in the open position. The tamping device consists of a trolley 1 on a rail track, removable vibrators 2, a power cylinder 3 with a rod 4 attached to a slider 5 located on the U-shaped guide 6 and enclosing it. With the slider 5 by means of the axles 7, the shoulders 8 are hingedly attached, fixed to the brackets 9 by means of the axles 10. Clamps II are attached to the brackets 9, in which vibrators 2 are placed with a free fit.

On the clamps 11 are pivotally fixed strips 12 attached in the upper part to semi-clamps 13 interconnected by a bolt 14. In semi-clamps 13 rubber shock absorbers 15 are inserted, covering the handle of the vibrator 2. A crossbar 16 is attached to the slider 5, to which the transmission links 17 are suspended, fixed by the second end on the rail rail 18 grips 18, which are two-piece 19. The grips are closed by means of springs 20. The grippers are mounted on the axles 21 of the trolley I.

On the frame of the trolley 1, racks 22 are fixed, on which the clips 23 are fastened, fixed with pins 24. Tamping blocks 25 are mounted on the vibrating rods 25, suspended from the yokes And on the rims 27. The rake 6 is attached to the guide 6 with the control panel 29.

Tamping device works as follows.

and installation of a tamping device on rails. A pneumatic power hose is then connected to the control console 29. The control crane includes a power cylinder 3 for lowering the slide 5, which, acting on the shoulders 8 and the brackets 9, lowers the vibrators 2, which, when the tamping blocks 26 touch the ballast, automatically turn on the vibration, since the strips 12 connected to the clamps 11 act on Vibrator handles 2. At the same time, the tamping blocks 26 are inserted into the ballast, the ballast is compressed on both sides of the sleepers and the ballast vibrates, which ensures high-quality tamping and shortens the cycle of the tamping.

When the control panel 29 is turned on to raise the vibrators 2 of the bar 12, raise the handle of the vibrator 2, the vibration is automatically turned off, which reduces energy consumption. When the vibrators 2 move upward under the influence of the power cylinder 3, the cross member 16 rises, while the transmission links 17, acting on the strips 18, compress the springs 20, parts 19 open. After that, the Tamper is moved to the next sleeper.
