chemins de fer caractdr:isée en ce -,Pelle utilise une fraiseùscie circulaire en acier rani<ie sono loc dont la vitesse de rotation est très lente en r'-lisant des copeaux, entraine par un moteur à tri s _i---1 i_ntensit sonore. .,ctuf nt, ces travaux sont exclusivement réalisés à l' ile de machines portatives bruyantes entraindes Par un moteur essence à deux temps et travaillant à l'aide d'un dis ue abrasif à tronçonner. Ce disque abrasif produit des :`t ir_el?es, et sa très grande vitesse de rotation (de l'ordre de ~.000 à 5.000 tours/minute) peut parfois être à l'origine de - ':clatement du disque abrasif, d'où la très grande danoe.r_ os '_t. travailler avec ce dispositif.  The railways are characterized by the use of a circular milling cutter made of high-speed steel, whose rotational speed is very slow when making chips, and is driven by a motor which has been sorted. i_ntensit sound. As a matter of fact, this work is carried out exclusively on the island of noisy portable machines driven by a two-stroke gasoline engine working with an abrasive cutting disc. This abrasive disc produces some irregularities, and its very high speed of rotation (of the order of ~ 000 to 5.000 revolutions / minute) can sometimes cause the abrasive disc to burst, hence the great danoe.r_ os' _t. work with this device.

D'autre part, leaoteur à essence à deux temps est toujours très bruyant, son .intensité sonore étant de l'ordre de 115 à 12.0 d ntensitc très largement supérieure aux normes acceptables et r' olernentaires. Egalement, lors des travaux de nuit, l'intensité sonore de ces moteurs peut être parfois à l'origine d'incidents très sérieux en provenance des riverains. En ce qui concerne l'aspect économique, un disque abrasif permet de rcal.=i.ser environ 3 coupes de rail au maximum , et du fait de le grande vitesse de rotation du disque, il peut arriver parfois un Achauffement de l' extrémité du rail qui est bleuie .  On the other hand, the two-stroke gasoline engine is still very noisy, its sound intensity being of the order of 115 to 12.0 degrees above the acceptable and over-rated standards. Also, during night work, the sound intensity of these engines can sometimes be the cause of very serious incidents from residents. With regard to the economic aspect, an abrasive disk makes it possible to weigh about 3 rail cuts at the maximum, and because of the high speed of rotation of the disk, it can sometimes happen that the end is warmed up. rail that is blue.

La r ebine selon l'invention remdie à tous ces inconvénients e> rmettant aussi de réaliser des économies d'exploitation 11.1 qu'elle présente les avantages suivants : 1) Sécurité tonale en cours de travail pour l'utilisateur : pas d'étincelle en cours de travail, et aucun risque d'éclatement du disque (réalisation de copeaux) . 2) Réduction importante du bruit de l'ordre de 20 à 25 dBA par l'entrainment à l'aide d'un moteur électrique ou à essence 3 euat.re temps avec silencieux. 3) Réduction du coût d'exploitation de l'ordre de 30 à 400 à cause de 3 - a îJombre de coupes environ 30 sans réaffutage 3 - b Gain de temps réalisée sur la fréquence du chancement du disque 3 - c "duction des frais d'entretien : les moteurs essence deux temps aspirent la limaille acier produite en cours de tronçonnage et obligent à réaliser de multiples réparations de ces moteurs. 3 - d Possibilité de ré-affuter la fraise-scie pour une nouvelle utilisation, ce qui réduit encore davantage le prix de revient des coupes 4) Importante amélioration de la qualité des coupes de rail (coupes blanches garanties) du fait de la faible vitesse 25 de rotation do la fraise-scie en acier rapide monobloc (vitesse de conne réduite) Pour ce la machine selon l'invention est principalement c =dractrisée par le fait qu'elle tronçonne le rail par l'utilisation d'une fraise-scie en acier rapide monobloc dont la vitesse de coupe est de l'ordre de 10 à 25 màtres/minute selon la dureté du rail à tronçonner . Selon un mode particulier de réalisation, un étau-support de fixation au rail comporte un bras d'articulation pouvant être démontable accouplé à une tête de tronçonnage actionnée par un moteur `lectrique, ou thermique à 4 temps avec silencieux d 'c anp -ment. Le support fixe au rail et la tête de tronçonnage peuvent être facilement accounlés ou désaccouplés pour faciliter leur transport en chantier. Un dispositif d'avance de coupe commandant la pénétration de 15 la fraise-scie l:ns le rail à tronçonner peut être prévu manuel ou automa tique Un dispositif de refroidissement de la fraise-scie en cours de travail de tronçonnage est prévu (non représenté sur les dessins) et compor.te un réservoir d'eau avec tuyauterie et 20 robinet. A titre d'exemple non limitatif, les dessins annexés illustrent L'invention La figure 1 renrsente en vue de face l'ensemble d'une machine plac~`e s pan rail de chemin de fer .  The reel according to the invention overcomes all these disadvantages and also makes it possible to achieve operational savings 11.1 that it has the following advantages: 1) Tonal security during work for the user: no spark in course of work, and no risk of bursting the disc (making chips). 2) Significant reduction of the noise of the order of 20 to 25 dBA by the drive with the help of an electric or gasoline engine 3 euat.re time with silencer. 3) Reduction of the operating cost of the order of 30 to 400 because of 3 - to the number of cuts approximately 30 without regrinding 3 - b Time savings made on the frequency of the chanting of the disk 3 - cost reduction maintenance: two-stroke gasoline engines suck up the steel filings produced during cutting operations and require multiple repairs of these engines 3 - d Possibility of re-sharpening the saw blade for a new use, which reduces further 4) Significant improvement in the quality of the rail cuts (guaranteed white cuts) due to the low speed of rotation of the monoblock high-speed steel cutter (reduced conne speed). The machine according to the invention is mainly c = dractrized by the fact that it cuts the rail by the use of a single-piece high-speed steel cutter whose cutting speed is of the order of 10 to 25 meters / minute. according to the hardness According to a particular embodiment, a clamp-mounting bracket to the rail comprises a detachable hinge arm coupled to a cutting head actuated by an electric motor, or 4-stroke thermal with silent d 'c anp -ment. The fixed support to the rail and the cutting head can be easily accounlés or uncoupled to facilitate their transport in the field. A cutting feed device controlling the penetration of the saw cutter into the cut-off rail can be provided manually or automatically. A cutter cooling device during cutting work is provided (not shown). in the drawings) and includes a water tank with piping and faucet.
