Definitions
- the invention aims to remedy this drawback.
- the reference 1 designates the ground level.
- a first pit was dug at a lower level 2, then a second narrower in the axis of the previous one at a level 3.
- the rails 4 of the track are carried by pillars 5 to a level higher than that of the ground .
- a carriage 6, or primary carriage On the bottom of the first pit, therefore at level 2, rolls a carriage 6, or primary carriage, supported by rollers 7 and guided in the longitudinal direction relative to the track by other rollers 8 with horizontal axis which carry against the vertical walls bordering the central pit (level 3).
- the carriage 6 in turn supports transverse rails 9 with a U-shaped profile, on which the rollers 10 of a secondary carriage can move.
- a vertical turret 12 equipped with two flanges 13 carrying rollers 14 of which can move rails 15 integral with a horizontal carriage 16 in the form of a cage.
- On the inner faces of the carriage 16 On the inner faces of the carriage 16 are articulated four arms 17, the ends of which are coupled to a part 18 so as to constitute two parallel deformable parallelograms.
- these parallelograms are arranged in two vertical planes symmetrical with respect to the mean vertical plane of the carriage 16. In the section of FIG. 2, only one of them can be seen. It will be noted that the two upper arms 17 extend opposite to the part 18 so as to carry a gear motor 19 capable of ensuring the control of the movement of the rectification stone, as will be seen below, and which also plays the role of counterweight balancing at least approximate the load that the arms bear 17.
- Fig. 1 clearly shows the conformation of the part 18, namely a vertical central part secured to two crosspieces at the ends of which the arms 17 are articulated.
- the central part is hollow and serves as a hub for a vertical axis which carries at the end a fork 20 oriented towards the top so as to constitute a first support.
- a horizontal axis 21 (fig. 3) which supports a frame or second support made of two lateral flanges 22 assembled by crosspieces 23 (fig. 1).
- the crosspieces 23 form sliding guides for a tool-carrying carriage 24 (fig. 1) which can thus move horizontally on them back and forth under the effect of a link 25 coupled to a crank pin 26 carried so offset by a plate 27 rotatably mounted on a lateral ear of the frame 22-23.
- the axis of this plate 27 is connected to the motor 19 by a flexible transmission 28 (fig. 2).
- the carriage 24 is extended upwards by a sliding part 29 suitable for carrying the abrasive stone 30 (FIG. 3) intended to rectify the collector 31 considered.
- this stone is slightly downstream of the lowest generatrix of this collector supposed to rotate in the direction of the arrow F in fig. 3 and 4.
- a suction nozzle 32 of relatively large section which opens in the immediate vicinity of the manifold 31 and substantially in the axis of this nozzle is arranged a blowing nozzle 33 of much smaller section supplied with pressurized air from a non-detailed pipe, which can be arranged inside the flexible pipe 34 (FIG. 3) to which the nozzle 32 is connected.
- the assembly of this nozzle 32 and the nozzle 33 is fixed to the carriage 24 so as to move back and forth with it.
- the chassis 22 is secured to a frame 35 suitable for coming to be disposed below the access opening 36 provided in the usual way in the bottom of the motor housing to which the manifold 31 corresponds.
- this frame are mounted vertical centering pins 37 urged upwards by individual springs 38, but which can be lowered against these using buttons 39, then snap into the erased position by bayonet notches 40 formed in guide sheaths 41.
- On the other hand on the frame 22 can be fixed a connecting piece 42 whose role will be explained below.
- the conventional arrangement consisting of a lateral control handle 43 (FIG. 1) which drives an endless screw 44, which in turn drives by a system of helical teeth a vertical shaft 45 comprising a threaded part engaged inside a corresponding threaded bore of said part 29.
- a lateral control handle 43 (FIG. 1) which drives an endless screw 44, which in turn drives by a system of helical teeth a vertical shaft 45 comprising a threaded part engaged inside a corresponding threaded bore of said part 29.
- This arrangement being well known in the art, the details have not been indicated in the drawing.
- the worm screw 44 with sliding key has been mounted on its shaft 46 in taking care to provide means, such as lateral retaining bearings, so that it remains centered with respect to the vertical shaft 45.
- a device has been incorporated into the lever 43. friction occurring in the direction of advance to limit the pressure of the stone on the collector.
- the motor to which the collector 31 to be rectified is then made to rotate in the direction of arrow F, which poses no difficulty, since the wheels which it drives are raised.
- the motor 19 is started up on the machine and, by the hose 28, controls the movement of the carriage 24 and consequently of the stone 30. It It then suffices to gradually approach the latter by the lever 43 so that it comes to bear against the collector and ensure its rectification over its entire length.
- the stone 30 is dismantled and replaced by a brush 48 (fig. 4), for example made of nylon.
- a brush 48 for example made of nylon.
- the locomotives or other vehicles on rails for which it is desired to rectify the manifold include an inspection door machined so as to be in a very exactly defined position relative to the manifold of the engine considered.
- the connecting piece 42 being removed, before raising the arms, care is taken to release the pins 37 so that they protrude clearly above the frame 35 (FIG. 5). They are then introduced into the perforations 47 provided in the edge of the opening 36 of the inspection door. We can thus very precisely center the frame 35, then fix it to the opening 36 by means of appropriate bolts. It is in particular possible to provide a number of pins 37 much lower than that of the perforations 47 and to use those of its last not traversed by such pins to receive the fixing bolts. We then proceed as described above.
