Description

METHOD FOR BALLAST TA M PING A RAILWAY TRACK POI] The sweatee relates to a method of iarapiag a track by -mesas of a tod tamper.

[0(52] Well-known hand tampers are gripped is as upper section comprising the drive and teve: a vibrating tamping blade which is immersed ism the ballast (see JDE I 241 424 B>. Paring: foe immersing operation, mm tries to achieve * compacting motion with the tamping blade m the: direeilon towards the sleeper by lowering the isppsr drive section in foe direction towards the operator. The compacting effect resulting írom this, however, is unsatisfactory since the ballast ~ used as a kind of abnlment: behind the tamping blade - does not offer much resistance doe to the vibrations, 1*3833 It is· the object of the present invention to provide a method of the type mentioned at the beginning with which If Is possible to achieve an Improved hallass compaction.

[084J According to the invention, this abject is achieved with a method of the specified kind hi that, prior to the immersion into the ballast, the hand tamper is detaehably connected to an anchor element, fixed to the track and lying opposite with: regard: to a tamping: motion, fey means of a fixing member fastened to a tamper section situated between a drive motor and a tamping blade, PS5| As a result of th is temporary connection to ihe track, a non-displaeeable abutment is created so that the downward: motion of the upper section of tire hand tamper causes & forced countermotion: of the usmpiog blade in the direction toward* foe sleeper, With fois, the ballast Is positively displaced underneath the sleeper and compacted, p86J Additional advantages of the invention become apparent Ire® the: dependent claims and foe drawing descrip-iot·. P87J The invention will be described in more detail below with reference to embodiments represented in the drawing in which Fig, 1 shows a view - in the longitudinal directiots of tbs sleeper - of two tend tempers. Fig, 2 show's a top view and Fig, 3 a simplified representation of a farther variant of foe invention.

[C1D8J Hand tampers L shown in Figs, 1 to 3, each have a drive motor 3, arranged in an upper section 2, má handles 4, A central tamper portion 6 provided between the drive motor 3 and a tamping blade 5 is configured as a connecting tube !7, having a longitudinal direction 7, in which an eccentric shah (not shown) is set in rotation. ffol9j Located above a sleeper 8, to be tamped, of a track 9 is an anchor element 10 in the shape: of s rail anchor which is: detachably connected to a rad 12 by means: of a quick fastener 11 and has hooks B. A iking member i 5 in the shape of a chain or rope, for example, is fastened to the connecting; tube 17 on a lmok M to: foe half of the tube lying closer to the taoipfog blades, fblbj To execute the tamping; method, the hook 14 Is connected fey means of foe fixing member 15 to a hook 13 of the anchor element 10 fixed to foe track. 1rs order to achieve an optimal compaction effect, the handle A together with the drive motor 3 is moved in a working direction lb towards the operator. Due to foe connection of foe central temper section 6 to the anchor element Mi, this produces a forced: tamping motion 18 of the tamping blade 5 m the direction towards the adjacent sleeper 8.
