FR3020384A3 - MANUAL BURNER FOR MURDER OF A RAILWAY - Google Patents

Abstract

The invention relates to a manual tamper for filling the ballast of a railroad track, with a tube (3) for the shaft, in which tube is housed the shaft and which is attached at a lower end to a stuffing blade ( 5), the tamping blade (5) being connected to a sleeve (6) provided with a cap (7) for covering the lower end of the tube (3) for the shaft, the sleeve (6) comprising a zone fastening device (10) spaced from the tamping blade (5) and marked by screws (13) for connection with the tube (3) for the shaft, an area (16) of the sleeve located between the fastening zone ( 10) and the stuffing scoop (5) having a length L formed to correspond at least to twice a height H of the stuffing scoop (5).

Description

The invention relates to a manual tamper for filling the ballast of a railroad track, with a drive motor for the rotation of a shaft provided with an unbalance, and with a tube for the shaft, in which tube is housed. the shaft and which is attached to a lower end spaced from the drive motor, to a stuffing blade. Such manual tamper is known from AI 239 296 or WO 2012/097960. The object of the present invention is to develop a manual tamping machine of the type stated at the beginning, which has better wear and maintenance characteristics. The object is achieved according to the invention with a manual tamper of the type stated, by the following features: (a) the stuffing scoop is connected to a sleeve adapted to be slidable in a longitudinal direction of the shaft on the tube for the shaft and being provided with a cap to cover the lower end of the shaft tube, (b) the sleeve comprises a fastening zone spaced from the stuffing blade in the longitudinal direction of the shaft and marked by unscrewable screws for connection with the tube for the shaft, (c) a zone of the sleeve located between the attachment zone and the stuffing shovel has a length L formed to correspond at least twice to a height H of the stuffing excavator. A manual tamping machine having these features of the present invention is distinguished by a cap 30 exchangeable according to its wear, the area of which having tube attachment means for the shaft is advantageously located outside the wear zone of the stuffing shovel. By this, it is possible to reliably prevent deterioration of the screws securing the cap 35 by ballast stones, and fully retain the function of the screws and their characteristic of being unscrewable.

Other features and advantages of the present invention will become apparent from the description of the drawings. Subsequently, the invention is described with reference to exemplary embodiments shown in the drawings.

In these drawings: FIG. 1 shows a view of a manual tamper of the invention, and FIGS. 2 and 3 and FIGS. 4 and 5 each represent enlarged views of the lower end of two variants of FIG. embodiment according to the invention of a manual tamper. A manual tamper 1 shown in Figure 1 comprises a drive motor 8 which is connected to handles 2 and a tube 3 for a shaft. In this tube, a shaft 9 is housed which is provided with an unbalance 11 and which is adapted to be rotated by the drive motor 8. At a lower end 4 of the tube 3 for the shaft, which is spaced apart from the drive motor 8, there is provided a stuffing pad 5 formed to be introduced into the ballast for stuffing the ballast of a railroad track. As can be seen more specifically in FIG. 3, the tamping blade 5 is connected to a sleeve 6 which can be slid in the longitudinal direction 12 of the shaft 25 on the tube 3 for the shaft (tube shown in FIG. 2), the sleeve 6 being provided with a cap 7 to cover the lower end 4 of the tube 3 for the shaft. In addition, an attachment zone 10 is provided on the sleeve 6 for connection with the shaft tube 3, the attachment zone 10 being spaced from the stuffing blade 5 in the longitudinal direction 12 of the shaft and being constituted in the present embodiment by a flange 14. This flange is associated another flange 15 disposed on the tube 3 for the shaft, which can be attached to the flange 14 by screw 13 unscrewable. An area 16 of the sleeve, located between the attachment zone 10 and the tamping blade 5, has a length L formed to correspond at least twice to a height H of the tamping blade 5. By this, the screws 13 are sufficiently far away from the stuffing pad 5 or the wear area thereof to avoid damage during stuffing. In the embodiment shown in Figures 4 and 5, the attachment zone 10 is formed by a tubular sleeve 17 attached to the sleeve 6, which is formed in two halves. When the sleeve 6 has been slid in the longitudinal direction 12 of the shaft on the tube 3 for the shaft, the two halves of the sleeve 17 are strongly pressed one on the other by means of unscrewable screws 13 and by this, the sleeve 6 is fixed together with the stuffing pad 5 on the tube 3 for the shaft.
