Definitions

  • the present invention relates to a method of replacing a tunnel burr wheel on the cutting head of a tunnel boring machine, and a device for handling the wheel and a wheel adapted to such a method.
  • a wheel is a cutting tool freely rotating on a shaft integral with the cutting head of a tunnel boring machine, see JP2007070825 or US4454923 .
  • the cutting head thus comprises a plurality of wheels distributed regularly on its surface.
  • the wheels are conventionally fixed in a housing on the cutting head by means of bolts.
  • the procedure of changing a wheel is to equip the wheel of lifting rings, to lift it with the aid of a hoist sliding along a rail, to load it on a carriage through the material airlock and back to the shield shield at atmospheric pressure.
  • An object of the present invention is therefore to implement a wheel replacement method that can reduce or eliminate any human intervention when replacing a wheel.
  • Another object of the invention is to provide a wheel that lends itself to such a method.
  • Another object of the invention is to provide a device for handling the wheel adapted for the implementation of this method, in particular to prevent any loss of components.
  • the device for handling the knobs must be easy to clean and not contain water retention zones or mud.
  • this device must be able to be used in existing cutting heads without requiring modifications thereof.
  • said method is implemented in an automated manner by means of a mechanized system fitted to the device for manipulating the wheel.
  • the wheel integrally carries the elements that allow its locking and prestressing in the housing.
  • the wheel is held by the handling device via its locking member.
  • a second object of the invention is therefore a wheel adapted for implementing said replacement method.
  • the locking member of said wheel is adapted to be immobilized, so that the wheel forms a rigid block for handling.
  • the locking member comprises a bayonet movable in rotation between a position of insertion of the wheel in the housing and a locking position of the wheel in the housing.
  • the prestressing means of the wheel may comprise screws which are integrally carried by the wheel.
  • said screws for prestressing the wheel are preferably carried captively by the bayonet.
  • a third object of the invention is a device for handling the wheel in the implementation of said wheel replacement method.
  • said device further comprises cleaning means of the housing.
  • said device preferably comprises means of transport, docking and / or clamping on the housing by a robot.
  • a fourth object of the invention is a tunneling machine comprising a cutting head and a plurality of knobs as described above and housings integral with the cutting head, said housings bearing fingerprints for locking the knurls.
  • Said housings advantageously have imprints for docking and guiding a device for manipulating the wheel as described above.
  • the knurls and housings advantageously carry complementary respective bearing impressions for centering and guiding the wheel in the housing.
  • each wheel is installed in its case under a prestress which allows it to withstand the efforts it will undergo during cutting.
  • the housing is fixed to the cutting head, typically by welding.
  • integral is meant that the various elements allowing the locking and prestressing of the wheel in the housing may have relative movements relative to each other, but they remain mechanically connected to each other without natural possibility of seperation.
  • the rear face of the cutting head (that is to say, as mentioned above, by the face opposite to the cutting edge) is brought to the housing device for manipulating the wheel whose structure will be described below by means of an example.
  • the feeding of the handling device can be carried out semi-automatically by means of a hoist or in a completely automated way, thanks to a handling robot.
  • the handling device and the housing have respective fingerprints that cooperate to allow guiding and docking of the device, handling on the housing.
  • clamping elements for example of the handling device or the robot carrier are actuated to ensure the locking of the device on the housing.
  • these clamping elements may consist of movable quarter-turn retaining pins arranged on the handling device to retain adequate impressions provided on the housing.
  • the next step comprises gripping the locking member of the wheel by the handling device.
  • the handling device advantageously comprises a suitable gripping element which allows the gripping of the wheel by means of the locking member of the wheel.
  • this gripping element comprises jaws able to grip the locking member of the wheel and operable in rotation between a locking position and a unlocking position of the wheel .
  • the handling device as described above uses the locking member of the wheel for gripping thereof, it would also be quite possible that the wheel has separate means to fill these two functions, namely a locking member and a gripping interface.
  • the next step of the method comprises releasing said preload.
  • the device for manipulating the wheel thus comprises extraction elements (for example cylinders) which make it possible to exert the necessary extraction force.
  • extraction elements for example cylinders
  • the housing is cleaned, for example by jets of water at high pressure, so as to insert more easily the new wheel .
  • the handling device can be cleaned before reuse to set up a new wheel.
  • a new wheel is fixed (more precisely, its locking member in the case illustrated here, or its gripping interface when the locking member does not fulfill the gripping function of the wheel ) on the handling device by means of the gripping element mentioned above.
  • the wheel is manipulable, it is arranged to make them stand in relation to each other its various components to form a rigid block.
  • the wheel 1 is held by the handling device at the bayonet 4 (the handling device is not illustrated on the Figures 1B to 1F to allow better visualization of the various components of the wheel and the housing).
  • the handling device supporting the wheel is brought opposite the rear face of the casing 2.
  • the front face of the housing is defined as being the face of which opens the rotating part of the wheel to the cutting edge; the rear face of the housing is the opposite face, by which the wheel is inserted.
  • the housing 2 carries imprints (not shown here) that allow pre-centering and guiding, then clamping, the handling device.
  • impressions are for example male forms arranged on its outer walls, constituting guide rails which cooperate with complementary female shapes arranged on the handling device.
  • the handling device is clamped on it by its clamping elements.
  • the gripping element of the handling device is then advanced to insert the wheel 1 to the stop in its housing inside the housing 2.
  • the wheel is automatically centered relative thereto.
  • the shape of the indentations 20 is provided to provide bearing surfaces for the ends of the wheel shaft in the front portion of the housing.
  • the gripping element which holds the bayonet 4 is actuated in rotation towards the locking position of the wheel 1 in the casing 2.
  • the bayonet 4 is rotated 90 ° and is housed behind footprints 21 (also visible on the figure 6 ) provided in the housing 2, which has the effect of locking the knob in the housing.
  • the actuating member of the manipulation device actuates the prestressing means of the wheel to apply prestressing from the rear of the casing, this force being supported by the bearing surfaces 20 of the casing 2.
  • the application of the prestressing can be done by simply tightening the screws 5 in the crossbar 6, or, preferably, by the use of jacks between the crossbar 6 and the bayonet 4 followed by the abutment of the screws 5 in the crosses 6.
  • the procedure using the assembly wheel-handling device has the advantage to be able to be implemented by a mechanized device, which makes it possible to reduce or eliminate a long and painful human intervention.
  • the centering of the wheel in the housing is done automatically by the walls of the housing, which avoids the use of shims as in existing wheels.
  • the housing being devoid of threads, it presents little risk of damage, and requires little repair.
  • the housing can be placed on an existing cutting head without requiring special adaptation thereof.
  • the figure 2 illustrates the wheel 1 inside the housing 2, one of the side walls of the housing does not appear.
  • the wheel 1 is freely rotatable about a shaft comprising two ends 10 disposed on either side of the wheel.
  • the ends 10 of the shaft have for example a polygonal shape which allows their interlocking on two supports 7 having a complementary shape (octagonal on the example of the figure 2 ), to which they are fixed by screws.
  • Said supports 7 are connected by a crosspiece 6 which has a general shape of U.
  • the supports 7 are fixed to the cross-member 6 by screws 70 (also visible to the figures 3 and 5 ) placed at the four corners of it.
  • the wheel 1 integrally carries a locking member operable between a locking position where the wheel is fixed in the housing 2, and an unlocking position for insertion and extraction of the knob casing.
  • this locking member comprises a bayonet 4 which is mounted on the crosspiece 6 by a pivot connection about an axis 40.
  • the wheel also integrally carries prestressing means in the housing.
  • prestressing means are preferably irreversible mechanical members such as bolts and / or cylinders arranged between the locking member and the cross member of the wheel.
  • these prestressing means are screws 5 captively carried on the bayonet 4 and which, when screwed with a suitable torque, apply to the wheel locked in the housing the prestressing desired intensity.
  • these components can be immobilized relative to each other to form a rigid block for handling the wheel.
  • the bayonet 4 may use another locking principle that the bayonet 4, as long as the fasteners are integral with the wheel and can be a rigid assembly for handling the wheel.
  • the figure 9 illustrates an example of manipulation device 3 of the wheel.
  • the device 3 comprises a frame 31, which supports elements for its centering and then clamping on the housing.
  • the centering elements are for example shapes arranged on the frame which cooperate with complementary shapes of the housing, thus fulfilling a guiding function of the device relative to the housing.
  • the clamping elements comprise four pins 33 in the shape of a quarter circle, and movable in rotation.
