Definitions

  • the invention relates to a machine for reprofiling rails comprising grinding or machining tools for reprofiling the running surface and the head of railroad tracks.
  • the reprofiling of the running surface and the head of railroad tracks is currently carried out by means of rail grinding trains or grinding machines.
  • These grinding trains consist of several grinding carriages comprising 8 to 10 grinding units per line of rails, dust extraction devices, a drive car and a control car.
  • Power supply to the grinding units, dust extraction devices etc. is carried out by means of several engine groups consisting of diesel engines, generators and hydraulic pumps which are arranged on several cars.
  • the grinding machines also have 8 to 10 grinding units per line of rails. They include a powertrain, a driving position and a drive system. These machines can be used either alone or coupled in grinding trains and for this purpose, they also include controls for multiple units.
  • the currently used grinding trains have the disadvantage that they are relatively long compared to the number of grinding units that they support and in addition that they often need additional cars to transport the suction devices necessary today. hui. In addition, these grinding trains with several machines mobilize a relatively large staff since 1 to 2 people are necessary for the control and command of each machine.
  • Figures 3 and 4 respectively represent a longitudinal section and a cross section of a car comprising a grinding carriage.
  • FIG. 1 shows the principle of construction of the grinding train according to the invention.
  • This train consists of a central car 1, a front car 2 and a rear car 3 which are connected together by the projecting articulation 4 of the central car 1.
  • the central car 1 is based on the tracks through bogies 5 which have driven axles.
  • the power supply installation 6 for the entire train and this installation includes a diesel engine, a transfer box, a generator and hydraulic pumps.
  • the generator supplies the energy required for all the grinding units, dust extraction devices and the control.
  • the axes are driven by the gearbox 7, the axes being connected to the diesel engine by a transfer box and through cardan shafts and transmission shafts 8.
  • central car 1 On the central car 1 are also tanks of diesel and oil 9 for the hydraulic circuit as well as the control cabinets 10 comprising the hydraulic and electric controls.
  • Measuring devices 12 of the longitudinal profile and of the profile across the rails are mounted under the central car 1. This central mounting of the measuring devices makes it possible to measure the condition of the track on the first pass before grinding and to shape the track immediately afterwards with the grinding units in the rear car. A passage used only to measure the actual condition of the rails is thus saved.
  • the front 2 and rear 3 cars have standard bogies 11 and are similarly constructed.
  • the air-conditioned cabins 13 which contain all the command and control elements for the drive device, the devices for representing the values measured by the devices for measuring the longitudinal profile and the profile in as well as the computers for controlling the grinding units.
  • Behind the cabins are water tanks 27 for a fire extinguishing installation.
  • grinding units In the front 2 and rear 3 cars there are twenty six grinding units, as shown in FIG. 2, these grinding units being distributed in two grinding carriages 14 each comprising two peripheral grinders per row of rails and in three grinding carriages 15 each comprising three cup wheels per row of rails.
  • the number of grinding units, the number of peripheral wheels and cup wheels can also be modified according to the deformation of the rails and the desired grinding capacity for each pass.
  • Figures 2 and 3 show in detail the mounting of the grinding carriages 14, 15 and the arrangement of the suction devices in cars 2 and 3.
  • the carriages 14 and 15, which are connected to the cars by means of draw bars and abutment rods 25 are lowered and raised by a wheelhouse constituted by connecting bars 16, pivoting levers 17, bars 18 and actuated by means of the cylinder 19.
  • the connecting bars 16 are adjustable in length and constructed in such a way that the grinding carriages can move freely during reshaping.
  • the bogies are first tilted towards each other and then brought to 6 mm above the upper face of the rail by means of the cylinder 19 controlled by the switch 21.
  • the bogies are brought to normal spacing, lowered onto the track and during grinding, they are pressed against the rails by means of cylinders 26.
  • the grinding carriages When the grinding carriages are raised, these are automatically centered in the chassis of the vehicle by the guides 22 and provided by the cylinder 24 with the axis 23 during movement.
  • the construction of the suspension and the control of the grinding carriages ensure that they can be brought into the working position simultaneously during the journey and regardless of the geometry of the track, and at the end of the reprofiling brought back and secured in their car .
  • suction devices which include cyclone separators, dust filters 28 and fans 29.
  • the dust generated by the grinding is sucked directly between the grinding wheels by the extension elbows 30 of the tubes 33 in the closed workspace which is formed between the removable doors 31 and the forms 32.
  • the dust resulting from grinding is thus sucked by the fans through the filters by means of the tube 33, which is fixed to the grinding carriage 14 and tube 34 which is part of the chassis of the car.
  • An additional fan draws the rest of the dust into the workspace through the discharge channel 35 which also brings it to the filters.
  • the doors 31 are adjustable in height by means of a cable tie and are guided by the profiles 36 fixed to the chassis of the car. During work, the doors are lowered to the ballast. Depending on the position of the grinding units, they are then reassembled automatically.
  • planing tools or milling tools can be mounted in at least one of the carriages in place of the grinding tools.
