专利摘要:
A tamping pick (5) for a tamping machine consists of a picking shaft (8) and a pick plate (9) positioned at its lower end and having a lower plate edge (10) spaced from the picking shaft (8). This has in the direction of the lower plate edge (10) spaced from each other and normal to this extending plate side surfaces (11) which connect a respective plate front side (12) with a plate back of the pick plate (9). On the pick plate (9) hard metal pads (14) are attached to increase the abrasion resistance. The hard metal supports (14) located next to each other along the bottom plate edge (10) form a common boundary line (15) both on the front plate side (12) and on the rear side of the plate. At each boundary line (15) then a from a plane (16) of the Plattenvorder- or rear side contrasting armor (17) is provided in the form of a build-up welding.

Tamping picks.
The invention relates to a Stopfpickei according to the preamble of claim 1.
Such a tamping pommel is already known from EP 1 329 554 A1. The entire plate front and back of the pimple plate are covered with carbide tips. In the area of the plate side surfaces cylindrical cemented carbide inserts are provided, which are positioned in corresponding holes of the picking plate.
The object of the present invention is now to provide a stuffing pick of the type mentioned, which can be produced efficiently and at the same time has a high abrasion resistance.
This object is achieved with a tamping pick of the generic type by the features stated in the characterizing part of claim 1.
Such an armor leads to an optimal protection of the hard metal pads in the end area. When welding, the use of different electrodes is possible, whereby different, abrasion-resistant materials can be applied. Even after very long periods of use of the stuffing tamp any repairs and repairs to the armor are easy to perform. The lifetime of the stuffed pot is thus significantly increased overall.

Comparison with an armor made of soldered carbide supports cheaper build-up welding significantly reduces the total cost of the stuffing peg.
Further advantages of the invention will become apparent from the dependent claims and the description of the drawings.
In the following the invention will be described in more detail with reference to embodiments shown in the drawing. 2 and 3 are perspective views of the front and rear sides of a stuffing patch, FIG. 4.5 are plan views, FIG. 6 is a view according to arrow VI in FIG. 4, and FIG. 7 is a side view of a variant of a stuffing pick.
A tamping machine 1 shown in Fig. 1 consists essentially of a supported on rail chassis 2 on a track 3 machine frame 4. At this stuffing tamping 5 exhibiting Stopfaggregat 6 is arranged for the suppression of sleepers 7 of the track 3.
The tamping pick 5 shown in detail in FIGS. 2 and 3 consists of a picking shaft 8 and a pick plate 9 positioned at the lower end thereof. This has a plate lower edge 10 that is distanced from the picking shaft 8. The pick plate 9 further has spaced apart in the direction of the plate lower edge 10 from each other and normal to this extending plate side surfaces 11. These each connect a plate front side 12 with a plate rear side 13 of the pimpling plate 9. On these, hard metal supports 14 are provided Abrasion resistance attached. The hard metal supports 14 located next to each other along the lower edge 10 of the plate form a common boundary line 15 both on the front plate 12 and on the rear side 13. Subsequent to each delimiting line 15 is a build-up weld which lifts off from a plane 16 of the plate front or rear side 12, 13 provided as an armor 17. The armor 17 is formed in the form of a parallel to the boundary line 15 extending bead 18. Each boundary line 15 and each weld bead 18 is arranged to extend parallel to the lower plate edge 10.
[010] Each weld bead 18 has a boundary plane 19 which is distant from the panel front or rear side 12, 13 and parallel to it. This is produced by milling the weld bead 18 and forms an extension of a ballast contact surface 20 formed by the hard metal supports 14. The armor 17 connected to the panel front 12 is positioned approximately centrally with respect to a panel height h (FIG. 4). The armoring 17 connected to the rear side 13 of the plate is positioned in a section 21 immediately following the lower edge of the plate 10 (FIG. 3).
FIGS. 4 to 7 show a tamping pick 5, the armor 17 of which is arranged on the plate front and rear side 12, 13 being connected by a lateral armoring 22, which is connected in each case to the side surface 11 of the plate. This also extends beyond the areas 23 of the plate front and back 12, 13 adjoining the plate side surfaces 11. The side armor 22 also formed from weld beads 24 are milled so that they form a common plane 26 with side surfaces 25 of the hard metal supports 14. The weld beads 24 located in the regions 23 are advantageously milled so that they are located within the boundary plane 19.
