Description

    FIELD OF THE INVENTION
  • 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.
  • BACKGROUND OF THE INVENTION
  • 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 .
  • During the rotation of the head and under the action of the thrust, the wheel rolls on the cutting edge and punches the rock in the form of flaking plates.
  • 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 problem of the change of the knobs arises particularly in the case of tunneling with confined front, since the access to the cutting head and fixations of the knobs is difficult and that the working environment is in hyperbaric conditions.
  • In such tunneling machines, the change of wheel is made, for security reasons, by the rear of the cutting head, that is to say on the side of the cutting head opposite to the cutting edge.
  • The procedure of changing the wheel frequently requires exerting significant efforts (ground stroke for example) to take off the used wheel from its case, due to jamming and the lack of guiding of the wheel, which is difficult to compatible with work in hyperbaric conditions.
  • At present, 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.
  • During disassembly, it is also necessary to collect all the elements (wedges, screws, bolts, etc.) necessary for fixing the wheel and that will be reused for the assembly of the new wheel.
  • Before inserting the new wheel in its case, it must be positioned properly, which requires a delicate manual intervention.
  • Once the wheel pushed to its position of use, it sets up several blocking wedges that are fixed by means of bolts.
  • We understand that this procedure is long and painful for operators.
  • 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.
  • Also, the device for handling the knobs must be easy to clean and not contain water retention zones or mud.
  • Finally, this device must be able to be used in existing cutting heads without requiring modifications thereof.
  • BRIEF DESCRIPTION OF THE INVENTION
  • According to the invention, there is provided a method for replacing a wheel mounted with prestress in a housing integral with the cutting head of a tunnel boring machine, implemented with a wheel integrally carrying a member for locking it in the housing and means for applying said prestressing.
  • The method comprises the steps of:
  1. a) removing a used wheel from said housing, comprising the steps of:
    • clamping on the housing, a handling device adapted for gripping and guiding the wheel,
    • gripping the wheel by the handling device,
    • release of the preload applied to the wheel,
    • unlocking the wheel vis-à-vis the housing,
    • extraction of the knob from the case,
    • unclamping the device for handling the housing,
  2. b) placing in said housing a replacement wheel, comprising the following steps:
    • gripping the wheel by the handling device,
    • docking then clamping the device for manipulating the wheel on the casing,
    • introduction of the wheel into the housing, said wheel being guided by the handling device,
    • locking the wheel in the housing,
    • application of a preload to the wheel.
  • In a particularly advantageous manner, said method is implemented in an automated manner by means of a mechanized system fitted to the device for manipulating the wheel.
  • For the implementation of this method, the wheel integrally carries the elements that allow its locking and prestressing in the housing.
  • This prevents any loss of components during the handling, disassembly and reassembly of the wheel.
  • According to a preferred embodiment of the method, 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.
  • According to a particular embodiment of the invention, 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.
  • Thus, 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.
  • More specifically, this manipulation device comprises:
    • a clamping element on the housing,
    • a gripping element of the wheel,
    • means for releasing or applying the prestress to the wheel,
    • a wheel extraction element
    • an actuating member of the locking member of the wheel.
  • Advantageously, said device further comprises cleaning means of the housing.
  • Furthermore, 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.
  • Finally, the knurls and housings advantageously carry complementary respective bearing impressions for centering and guiding the wheel in the housing.
  • BRIEF DESCRIPTION OF THE DRAWINGS

    • the Figure 1A has a wheel in a housing and a device for guiding the wheel in a wheel change situation,

    • the Figures 10A and 10B respectively show an example of handling device mounted on a semi-automated positioning means and an example of

  • DETAILED DESCRIPTION OF THE INVENTION
  • During the commissioning of the tunnel boring machine, each wheel is installed in its case under a prestress which allows it to withstand the efforts it will undergo during cutting.
  • Conventionally, the housing is fixed to the cutting head, typically by welding.
  • As will be seen below, the procedure of setting up and extracting the wheel is facilitated by the fact that the locking and prestressing elements are integral with the wheel.
  • By "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.
  • Method of replacing a wheel
  • The extraction of a used wheel from its housing is implemented in the following steps.
  • Removing a used wheel
  • Initially, 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.
  • Once in position, clamping elements for example of the handling device or the robot carrier are actuated to ensure the locking of the device on the housing.
  • As will be seen below, 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.
  • For this purpose, 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.
  • It further comprises an actuating member adapted to actuate the unlocking of the wheel vis-à-vis the housing.
  • For example, in the example of a device which will be described below, 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 .
  • Note that if 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.
  • At this point, the wheel is always preloaded in the housing and locked in it.
  • The next step of the method comprises releasing said preload.
  • For this purpose, when this preload is provided by screws, the device for manipulating the wheel unscrews said screws.
  • We can then unlock the wheel vis-à-vis the housing, by actuating the unlocking element of the handling device to the unlocking position of the wheel.
  • So that the wheel is manipulable for its extraction, it is necessary that all of the integral elements of the wheel are immobile relative to each other to form a rigid block.
  • For this purpose, it resets the locking member of the wheel in such a way that the elements of the wheel become stationary relative to each other.
  • In the case illustrated Figures 1B to 6 , where the locking member of the wheel 1 is a bayonet 4 pivotally connected to a cross member 6 and wherein the biasing means of the wheel 1 are screws 5 carried by the bayonet, this amounts to screw the screws 5 to constrain the bayonet 4 against the cross member 6 of the wheel.
  • It is then possible to extract the wheel from its case, the components of the wheel being stationary relative to one another and constituting a rigid block.
  • A relatively large effort is required, because of the bracing mainly resulting from operating stresses that jam the wheel in its housing.
  • The device for manipulating the wheel thus comprises extraction elements (for example cylinders) which make it possible to exert the necessary extraction force.
  • Once the knob extracted from the housing, unclamps the handling device vis-à-vis the housing, then the housing is cleaned, for example by jets of water at high pressure, so as to insert more easily the new wheel .
  • Finally, the assembly consisting of the handling device and the wheel is conveyed to the workshop where the used wheel will be dismantled.
  • The handling device can be cleaned before reuse to set up a new wheel.
  • Setting up a replacement wheel
  • To install a new wheel in the case, proceed in the reverse order of these steps.
  • To describe these stages of assembly, we will use as an example Figures 1B to 1F , but it is understood that these figures show only a particular embodiment of the wheel and the method is not limited to the establishment of this particular wheel.
  • Firstly, in the workshop, 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.
  • So that the wheel is manipulable, it is arranged to make them stand in relation to each other its various components to form a rigid block.
  • With reference to the Figure 1B , 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.
  • It is specified that 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.
  • These 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.
  • Once it is in a centered position on the housing, the handling device is clamped on it by its clamping elements.
  • With reference to the figure 1C , 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.
  • Thanks to the imprints 20 arranged in the inner walls of the housing 2, the wheel is automatically centered relative thereto.
  • On the other hand, 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.
  • With reference to the figure 1D , the screws 5 which held the bayonet 4 in constraint against the crossbar 6 are then unscrewed, so as to allow the rotation of the bayonet.
  • With reference to the figure 1E , the gripping element which holds the bayonet 4 is actuated in rotation towards the locking position of the wheel 1 in the casing 2.
  • In the case illustrated here, 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.
  • It is then a question of putting the wheel in prestressing so that it can resist the forces undergone during the cut.
  • For this purpose, 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.
  • This is an "irreversible" prestressing, in that the means of applying the prestressing do not allow to release it in the absence of action by an operator.
  • In the case illustrated in figure 1F the screwing heads of the handling device screw the screws 5 to the desired torque.
  • The establishment of the wheel with prestressing being completed, detach the handling device of the wheel and unclamp the housing.
  • The implementation of the method which has just been described has been made possible by the design of a new wheel structure and a new device for manipulating the wheel, which will be described successively below.
  • Compared to the known procedure in which the wheel is placed on the cutting head and then fixed and constrained by means of screws and shims, 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.
  • Furthermore, 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.
  • It can also be noted that the housing being devoid of threads, it presents little risk of damage, and requires little repair.
  • Finally, the housing can be placed on an existing cutting head without requiring special adaptation thereof.
  • However, it is understood that a manual setting of the wheel as practiced in the prior art remains possible; this setting up is even facilitated by the fact that the wheel bears integrally all the elements necessary for its attachment, which frees operators from handling the screws and shims usually used.
  • Example of a wheel adapted to the implementation of the method
  • We now describe, with reference to Figures 2 to 6 a wheel design adapted to the implementation of this method.
  • This is the wheel illustrated in the Figures 1B to 1F which have been commented on above.
  • The figure 2 illustrates the wheel 1 inside the housing 2, one of the side walls of the housing does not appear.
  • In a manner known per se, 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.
  • Furthermore, 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.
  • Here, 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.
  • These 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.
  • By "irreversible" is meant in the present text that these organs can not relax the constraint applied without intentional intervention with a disassembly device.
  • In the example illustrated here, 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.
  • It is important to note that all the components necessary for locking the wheel in the casing and for prestressing the wheel (that is mainly, in the example illustrated here, the bayonet 4 and the screws 5) are integral with the wheel, that is to say that they are mechanically linked to it without the possibility of disassembly other than intentional dismantling (for example for a repair).
  • Furthermore, these components can be immobilized relative to each other to form a rigid block for handling the wheel.
  • It goes without saying that the skilled person may consider a different wheel structure, also used in the method described above, without departing from the scope of the present invention.
  • For example, it 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.
  • Likewise, the number of screws represented in these figures is only indicative, and the person skilled in the art may quite modify the number of screws, and / or propose other means of applying prestressing to the wheel, without departing from the scope of the present invention.
  • Device for manipulating 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.
  • In the example illustrated here, the clamping elements comprise four pins 33 in the shape of a quarter circle, and movable in rotation.
  • These pins 33 are housed in grooves arranged on the housing so as to secure the frame 3 on the housing 2.
  • The device 3 also comprises an actuating member 36 housed in the frame 31.
  • Here, the actuating member is movable in translation (by means of jacks 35) and in rotation with respect to the frame 31.
  • The device 3 further comprises a gripping element adapted to hold the wheel, and more particularly the locking member thereof.
  • The gripping element is mounted on the actuating member 36, and is thus operable both in translation to insert or extract the wheel from the housing and in rotation to lock or unlock the wheel in the housing.
  • In the example illustrated here, the gripping element comprises jaws 34 adapted to grip the bayonet 4 of the wheel.
  • The jaws 34 may deviate a distance greater than the bayonet width to allow its gripping or release, and move closer to firmly hold the bayonet.
  • Thanks to their connection with the actuating member, the jaws 34 are also rotatable at least a quarter of a turn between a position where the bayonet is in position allowing insertion of the wheel in the housing, and a position where the bayonet is in the locking position of the wheel in the housing.
  • The handling device 3 further comprises means for applying or releasing the prestressing at the wheel, which cooperate with the means for prestressing the wheel.
  • These means comprise screwing heads 32 connected to screwdriver bodies 37, mounted in the actuating member 36, and adapted to screw or unscrew the screws 5 for prestressing the wheel.
  • The device 3 furthermore comprises extraction elements of the wheel.
  • In the example illustrated here, these extraction means are cylinders 35 arranged between the frame 31 and the actuating member 36.
  • In the situation illustrated in Figure 7A , where the wheel 1 is in its operating position in the housing 2, the frame 31 of the device 3 is clamped on the housing 2 by means of the pins 33 and the cylinders 35 are in the retracted position, so that the body of actuation 36, and thus the jaws 34 and the screwing heads 32 can respectively actuate the bayonet and the prestressing screws of the wheel.
  • In the situation illustrated in Figure 7B , where the wheel 1 is extracted from the casing 2, the frame is still clamped to the casing 2 by the pins 33, but the cylinders 35 are in the extended position, which has the effect of moving the actuating member 36 backwards. , and thus the jaws 34 which hold the bayonet.
  • The device 3 may also include any other component that the skilled person deems useful.
  • Thus, for example, it comprises means (not shown) for cleaning the housing after extraction of the used wheel.
  • These means may consist in particular of jets of water at high pressure.
  • In the example shown in figure 9 (as well as figure 10A , where it is shown in perspective with the wheel), the frame 31 of the handling device is surrounded by a hoop 38 which is intended to be attached to a hoist (not shown).
  • This corresponds to a semi-automated execution mode, which can be implemented for example in degraded mode, during maintenance operations.
  • The figure 10B illustrates for its part an embodiment of the handling device 3 intended to be mounted on the end portion of a robotic handling effector, which is preferably used for the operation of the tunnel boring machine.
  • This figure shows only a front plate 42 of the handling robot, which has a recess for receiving the handling device.
  • Said robot is notably animated with a translation movement in the axis of the housing, and has control means of the handling device.
  • The handling device 3 is connected to the plate 42 by a set 41 of hexapod-type cylinders, which makes it possible to bring the device 3 to lock it on the housing and then remove it.
  • The manipulation device which is illustrated is particularly adapted to the wheel shown.
  • Naturally, the shape of the components of this handling device may vary depending on the shape of the corresponding wheel, without departing from the scope of the present invention.
  • Finally, it goes without saying that the examples that we have just given are only particular illustrations in no way limiting as to the details of implementation of the invention.
