Definitions

  • the invention relates to a wall saw, in particular a wall saw for making flush cuts in concrete and the like, according to the preamble of patent claim 1.
  • the invention also relates to a saw blade for use in connection with such a wall saw according to the preamble of patent claim 8.
  • Wall saw systems are devices for cutting reinforced or non-reinforced concrete walls with the aid of rotating saw blades equipped with cutting segments and are described, for example, in the company brochures of the applicant No. W 1881 594 10-d, 1994 and W 1838 993 10-d, 1993. They are used in building construction, civil engineering, renovation of buildings and renovations. For example, during demolition work in the event of renovation, when making corrections or for the construction of connecting buildings, it may be necessary to cut through existing concrete walls, remove them or cut out areas from the concrete walls. While in a large number of applications the cuts can be made in areas of the concrete walls where there is sufficient distance from the adjacent walls, the ceiling or the floor, there is a requirement in particular for cuts for the construction of connecting structures or cutouts for doors and the like flush cuts. This means that the cut must, for example, be flush with an adjacent, vertical wall or, in the case of door cutouts, flush with the floor or ceiling.
  • a saw blade with a smaller starting diameter of, for example, 600 mm or 700 mm is always installed and a pre-cut is made. Then the saw blade, for example in increments of 200 mm to 300 mm, is exchanged one or more times for a saw blade with a larger diameter in order to make the cut at the required depth.
  • the saw blades with larger diameters are guided on both sides in the previously created cut and can therefore no longer deform axially.
  • Changing the saw blades is relatively cumbersome and takes a relatively long time. It should also be borne in mind that a saw head weighs around 30 kg and more and the saw blades weigh up to 70 kg. To lift off the running rail and put the saw head back on the running rail, the operating personnel must therefore lift and adjust a weight of 100 kg and more. It should be taken into account that this must also be done in very confined spaces in flush-cut applications.
  • the saw blade is heavy, particularly bulky and cumbersome to manipulate, especially with large diameters, and is difficult to lift. Therefore, with the known fastening devices for the saw blades and in particular with known flush cut flanges, changing the saw blade is always associated with a relatively great physical effort for the operating personnel.
  • the object of the present invention is therefore to improve a wall saw in such a way that the saw blade change can be carried out more easily and quickly. It should be possible to change the saw blade even in confined spaces, such as occur in particular in flush cutting applications, without having to lift the saw head from the running rail and tilt it. The saw blade change should largely be possible without the operator lifting the saw blade.
  • the saw blade should also be prepared in such a way that lifting the saw blade if necessary, for example in order to remove a replaced saw blade from the work area, can be carried out in a simpler way than before.
  • the solution to these problems consists in a wall saw and in a saw blade as defined in the characterizing sections of claim 1 and claim 8, respectively.
  • the wall saw according to claim 1 comprises a saw head which is longitudinally displaceable on a running rail and has a pivotable Saw arm and a saw blade with cutting elements detachably attached to the saw arm, which can be rotated via a drive unit attached to the saw arm and connected to a drive unit.
  • the saw blade is attached to the saw arm via a coupling, which comprises two telescoping flange halves which can be releasably connected to one another, one flange half of which is attached to the flat side of the saw blade facing the saw arm and the second flange half is arranged on the saw arm.
  • the inventive design of the coupling with two flange halves makes changing the saw blade significantly easier.
  • the saw blade no longer has to be removed from the flange half. Only the connection between the two flange halves has to be released in order to be able to remove the saw blade. Then only the saw arm has to be reset, with one flange half sliding out of the other.
  • the first half of the flange remains connected to the replaced saw blade.
  • the loosened saw blade can, for example, be rolled out of the cut. Then a saw blade with a larger diameter is rolled into the previously created cut, the first flange half already connected to it facing the second flange half.
  • the first flange half only has to be aligned in such a way that the two flange halves can slide into one another by automatically adjusting the saw arm.
  • the two nested flange halves then only have to be connected to one another.
  • a very important advantage of the coupling according to the invention between the saw head or saw arm and the saw blade is that all manipulations can be carried out from that side of the saw head which is freely accessible even in flush cutting applications.
  • the necessary lifting manipulations of the saw blade are essentially restricted to the alignment of the first flange half to the second flange half in the case of vertical cuts and flush cuts in the base area.
  • the alignment of the flange halves takes place when changing the saw blade only after the new saw blade has been rolled into the cut already made. Alignment is therefore relatively unproblematic, since the saw blade is supported in the previously created cut and secured against falling over.
  • a drive spindle is provided on the drive unit, on which the second flange half is rotatably mounted. In this way, the torque is transmitted directly to the saw blade via the flange halves.
  • a central counterpart is inserted through a central hole in the flange half and onto the drive spindle screwed on. As a result, the flange half is centered and fixed and can, if necessary, be removed or replaced very quickly.
  • the first flange half connected to the saw blade is designed as a mother flange and has an approximately V-shaped recess that opens to the circumference of the first flange half.
  • the approximately V-shaped recess serves for receiving and centering for a correspondingly shaped, approximately V-shaped projection which protrudes from the side of the second flange half which is designed as a father part and faces the saw blade.
  • the appropriate design of the flange halves facilitates the automatic sliding of the two flange halves by adjusting the saw arm.
  • the two flange halves Due to the approximately V-shaped shape of the recess on the mother flange half with an approximately funnel-shaped enlarged mouth and the corresponding V-shaped shape of the projection on the father flange half, the two flange halves can still be reliably pushed together even if the alignment is not exact, since at the start of the pushing together the narrowest Area of the projection in the widest recess in the mouth area is performed.
  • the geometry selected results in an automatic self-alignment of the two flange halves.
  • the clear width of the recess increases over its depth and the width of the projection correspondingly decreases over its height in the direction of the end face of the second flange half in such a way that the two flange halves are fitted together precisely when pushed together.
  • the recess in the first flange half is thus undercut in depth, while the projection is provided with correspondingly bevelled side walls. In this way, the projection slides into the undercut recess with a precise fit.
  • the two flange halves are automatically axially secured in the assembled state and also have no axial play.
  • approximately radially arranged locking screws are advantageously provided on the circumference of the first flange half, which can be screwed into corresponding radial bores with an internal thread on the circumference of the second flange half. Due to the radial arrangement, the securing elements are practically not subjected to shear stresses during operation and they only have to counteract radial forces.
  • the flange halves are equipped with an anti-rotation lock in an advantageous embodiment variant, which prevents rotation of the saw blade in the absence of radial locking of the joined flange halves. In this way, the wall saw can only be put into operation if the flange halves are secured radially.
  • the anti-rotation device comprises a ring arranged on the circumference of the second flange half, which can be pushed over the first flange half when the locking screws are screwed in flush with the surface and can be detachably fixed there.
  • the ring On its side facing away from the saw blade, the ring has at least one projecting cam which, in the radially unsecured state of the two flange halves, interacts with means arranged rigidly on the saw head or the saw arm, for example a saw blade guard, in order to prevent rotation of the saw blade. If the ring is pushed over the first flange half, it forms an additional radial securing of the two flange halves pushed together. Even if the radial locking screws fail, the two flange halves are still prevented from sliding apart radially by the ring.
  • the invention also provides a saw blade for use with a wall saw, which is connected on its side facing the saw head to a flange designed as a nut part, which has an opening which is approximately V-shaped and opens to the circumference of the flange half has, the width increases over its depth.
  • the flange half can be made integrally with the saw blade, it proves to be advantageous if the nut flange half is detachably connected to the saw blade.
  • a number of screws are provided which can be pushed through from the flat side of the saw blade facing away from the mother flange half, preferably at the same distance from one another, through holes in the saw blade and which can be screwed into the holes in the nut flange half flush with the saw blade.
  • already existing saw blades with prepared bores with a mother flange half designed according to the invention can be used be retrofitted so that they can be used with a wall saw, on the saw head or saw arm of which a parent bottle half is arranged.
  • a support element can be detachably connected to the saw blade, which comprises at least one handle that is connected to a flange half, the outer contour of which is designed to correspond to the cutout on the first flange half.
  • the flange half has an approximately V-shaped shape and has a width which decreases over the height of the flange half in a manner corresponding to the width of the recess on the first flange half that the two flange halves are axially fixed in the assembled state.
  • the saw blade created in accordance with the general inventive concept and the supporting element are equipped with a coupling which comprises two flange halves according to the invention.
  • the support element can be coupled to the saw blade very easily in order to facilitate lifting of the saw blade.
  • the flange halves are held together by the weight of the saw blade when the saw blade is carried. After the saw blade has been set down, the supporting element can simply be removed again by pulling the flange half out of the recess in the flange half connected to the saw blade.
  • a wall saw system of the generic type is provided with the reference number 1. It comprises a, usually hydraulic, drive unit 2, which is connected to a saw head 4 of a wall saw via hydraulic lines 10.
  • the saw head 4 is longitudinally displaceable on a running rail 3 and has a vertically pivotable saw arm 5 to which a saw blade 6 equipped with cutting elements is rotatably fastened.
  • FIG. 2 shows a saw head 4 with a pivotable saw arm 5.
  • the guide rail 3 carrying the saw head 4 is designed as a profile rail and is supported above the floor by rail feet 3a.
  • the saw head 4 has rollers 7 on its support side, which facilitate its longitudinal displacement on the running rail 3.
  • the vertically pivotable saw arm 5 connected to the saw head 4 carries a drive unit 8, by means of which the saw blade (not shown) can be rotated.
  • the drive unit 8 comprises a drive spindle, which is connected to coupling elements for the saw blade.
  • Hydraulic connections 9 are provided on the saw head 4 and on the saw arm 5, via which the drive unit 8 is connected to the drive unit in order to be able to set the drive spindle in rotation or to allow the saw arm to pivot. Also shown in FIG. 2 is a saw blade protection holder 28, which has a connection (not shown in more detail) for the flushing water supply. So far, the device corresponds to the wall saws well known from the prior art, which are also sold by the applicant.
  • the coupling elements comprise two flange halves 11 and 17 which can be pushed together and releasably connected to one another.
  • first flange half 11 is designed as a mother flange half and is connected to the saw blade 6.
  • the mother flange half 11 has a screw plate 12, which is preferably provided with the same spacing from one another and bears against the one flat side 29 of the saw blade 6 in the assembled state.
  • fastening screws 14 are inserted from the second flat side 30 of the saw blade 6 through holes in the saw blade 6 and screwed into the internally threaded holes in the screw plate 12 of the nut flange half 11.
  • the heads of the six fastening screws 14, for example, are flush with the second flat side 30 of the saw blade 6.
  • a centrally arranged, circular projection 15 can be arranged on the side of the screw plate 12 which bears against the saw blade and protrudes into a central bore in the saw blade 6 during assembly.
  • the mother flange half has a depth d which is approximately 5 mm to approximately 20 mm.
  • a depth d which is approximately 5 mm to approximately 20 mm.
  • an approximately V-shaped recess 13 is provided which opens towards the circumference of the flange half 11.
  • the clear width w of the recess increases in the depth d of the recess 13 towards the screw plate 12.
  • the recess 13 has an undercut.
  • Radially arranged locking screws 21 are provided on the circumference of the nut flange half 11, which protrude into the recess 13. Their function will be explained later.
  • a second flange half 17 of the coupling elements according to the invention is shown.
  • the second flange half 17 forms the counterpart to the mother flange half connected to the saw blade and is designed as a father part.
  • the second flange half 17 is approximately can-shaped and has a projection 19 which projects from that side 18 which faces the mother flange half.
  • the projection 19 is shaped corresponding to the recess on the mother flange half and therefore has an approximately V-shaped shape.
  • the width b of the projection 19 decreases from its greatest width on its contact surface 20 over its height h to the extent that the clear width of the recess on the nut flange half increases over the depth.
  • the depth of the recess in the mother flange half and the height of the projection on the second flange half correspond to one another. In this way, the two flange halves are axially secured in the collapsed state and also have no axial play.
  • the second flange half 17 is firmly connected to the drive unit on the saw head or on the saw arm.
  • it has a central bore 22 for receiving the drive spindle of the drive unit.
  • the drive spindle is fixed, for example, by a counterpart, which is screwed onto the drive spindle from the side of the contact surface 20 and thereby fixes the second flange half.
  • a flange can be provided on the drive spindle, to which the second flange half is screwed. 5 are indicated in the contact surface holes, which are used for receiving the fastening screws.
  • FIG. 7 shows the mother flange half 11 and the second flange half 17 in the pushed-together state.
  • the illustration shows the rear side of the second flange half 17, which is connected to the drive spindle.
  • the radial locking screws 21 on the circumference of the mother flange half 11 have not yet been screwed into the corresponding bores with an internal thread in the projection of the second flange half 17.
  • the ring 23 On its side facing away from the mother flange half 11 or the saw blade, the ring 23 has a projecting cam 24.
  • this projecting cam 24 acts with means arranged rigidly on the saw head or on the saw arm, for example with the reference number 28 in FIG. 2 designated blade guard holder, and prevents rotation of the saw blade until the two flange halves 11, 17 pushed together are also fixed radially by screwing in the radial locking screws 21. Only then can the ring 23 be advanced over the circumference of the mother flange half 11 to the screw-on plate 12. In this position, the ring 23 is locked, for example, by a spring-loaded, pin-shaped bolt, not shown, which is arranged in the second flange half 17 and engages in the bore 31 in the ring 23.
  • the protruding cam 24 comes out of engagement with the saw blade guard and the saw blade can be rotated.
  • the ring 23 forms an additional radial securing for the two flange halves 11, 17 by preventing them from sliding apart radially.
  • the spring-loaded, pin-shaped bolt To release the coupling, the spring-loaded, pin-shaped bolt must first be brought out of engagement with the bore 31 in the ring 23. This is done, for example, by pressing in the bolt, the ring 23 being withdrawn from the circumference of the nut flange half 11 at the same time. As a result, the two flange halves 11, 17 are released again and can slide apart after loosening the screws 21.
  • FIG. 8. 9 shows an embodiment of the support element 25. It has two carrying handles 26 which are provided on a horizontal tube or rod. The horizontal rod is connected to a flange half 27, which is designed as a counterpart to the recess in the mother flange half 11.
  • the flange half 27 has an approximately V-shaped outer contour. The width b of the flange half 27 decreases over its height to the extent that the clear width of the recess in the nut flange half increases over its depth. In this way, the two flange halves 11, 27 are axially secured in the assembled state. It is not so much a question of the axial fit or the correspondence of the height of the flange half 27 and the depth of the recess on the mother flange half 11, since a slight tilting of the saw blade does not play a role when lifting.
