    专利说明:

    The invention relates to a wire saw having the features of the preamble of claim 1. In addition, the invention relates to a mobile support device with a wire saw.
    Wire saws are known. Wire saws are used to cut workpieces, usually large solid objects, such as natural stones, with motor-driven sawing wires, i. The wire saws are used to cut a workpiece (e.g., a block of stone) that has already been released from a superordinate contiguous assemblage (e.g., a mountain). Previously known wire saws can be subdivided into stationary wire saws and wire saws which can be brought to the workpiece.
    In known stationary wire saws, an endless sawing wire with diamond segments is guided over two deflection rollers. On the one hand, it is problematic that the workpieces to be cut can not be cut on site (for example, at the place where they are being dismantled) but are transported to the wire saw. Need to become. On the other hand, the problem is that the wire saw by the fixed distance of the two pulleys has a fixed and limited cutting width and cutting height and can only work on rope pressure, the cable tension is not variable. Due to these factors, the workpiece to be cut is also limited in weight and size for stationary wire saws.
    In known wire saws, which can be brought to the workpiece, there is a disadvantage, in particular, in that the workpieces must be guided for cutting to the sawing wire, in particular raised. This is particularly problematic because it is very difficult to control the mostly massive workpieces, so that it is practically only very sulfur to perform a controlled guided cut.
    In 'other known wire saws, which can be brought to the workpiece, the endless sawing wire is guided around a fixed to a track car mounted pulley, with guide pulley • II * ·· * ···· ···· and rail cars a functional unit for sawing form. It must be performed a hole in the workpiece to perform the sawing wire starting from the deflection roller under or through the workpiece can. The sawing wire is deflected in the area of the bore and then leads again to the deflection roller on the carrier device. However, these wire saws can not be easily brought from workpiece to workpiece, since they are very complex and with each piece of work and dismantled must. The disadvantage is that the sawing cable must be opened in order to perform this through the workpiece. This is particularly problematic because the sawing cable is not guided accurately and thus no accurate cut can be performed. Since the sawing wire is also guided around sharp edges in the inlet region in the workpiece or in the exit region of the workpiece, it is subject to increased wear, especially at the gate of the workpiece. There is an increased risk of injury due to cable breakage, in which a relatively long section of the sawing cable-in particular the section of the sawing cable extending from the exit area from the workpiece to the deflection roller-can deflect like a whip. On the one hand, this makes the safety zone in the area of the wire saw very large. On the other hand, the pulley can not be attached to a commercial vehicle, as a possible knocking out of Sägeseiles represents an excessive safety risk to the driver of the commercial vehicle. It is also not possible or very difficult to selectively supply cooling water.
    For comminuting the workpiece, the track car is moved on tracks away from the workpiece to exercise the cable for sawing. If the track car has come to the end of the track and the workpiece has not yet been completely cut, the saw saw must be switched off and the saw wire opened and shortened. Subsequently, the track car is moved again in the direction of the workpiece, the shortened sawing wire is closed and it can only be started again sawing, the above-mentioned risks occur again at the gate of the workpiece. Although the known track car can be moved on the site on a limited track section but not mobile, since it can only be transported to the place of use by a mobile vehicle and is not movable regardless of the consuming up and down tracks.
    The invention is based on the object to provide a wire saw available, with which problems and disadvantages of the prior art are overcome.
    This object is achieved according to the invention with a wire saw, which has the features of claim 1.
    In addition, this object is achieved with a carrier device having the features of claim IS.
    Preferred and advantageous embodiments of the invention are subject of the dependent claims.
    According to the invention it is provided that the wire saw has a changing device for attachment to a mobile support device. Under " mobile " is understood in the context of the invention, in particular, that the carrier device can change the position as desired. Within the scope of the invention, the mobile carrier device may be a carrier vehicle, in particular a powered commercial vehicle, depending on the field of use, e.g. a wheeled excavator, a crawler excavator, a telescopic loader, a wheel loader, a tractor with a front loader, or the like. Thus it is achieved that the mobile wire saw to the place of use, e.g. also to exposed stones, can be transported out, the workpieces can be divided on site. A complex and costly transport of the workpieces to the wire saw out is therefore no longer necessary. The. Period of time until the workpiece is completely cut, is substantially reduced.
    Since the wire saw according to the invention can be used on a carrier device mobile, it is further achieved that no longer the
    Workpiece led to the sawing wire, in particular raised must be, but that now the sawing wire can be guided to the workpiece. This is particularly advantageous because it is thus particularly easy to carry out a guided cut.
    The more controlled the cut can be made, the finer the cut can be made. Thus, less material is lost on the workpiece to be cut and, as is known, it falls within the area of the cut. Cooling water is supplied to less cutting sludge. The finer the cut can be made, the more the permanent mechanical loads on the sawing wire are reduced, so that in particular. In terms of maintenance of the wire saw and the renewal of the sawing wire less tool costs incurred and the reliability is increased.
    In contrast to the known wire saws, which can be brought to the workpiece, the reliability is increased in several respects with the wire saw invention. Since the sawing wire is guided to the workpiece and can work on rope pressure - and is no longer guided by a hole around sharp edges to train - the risk is significantly lower that the sawing wire breaks. Even if the saw-wire were to rupture, a "whip-strike effect" would not be pronounced as described above. occur because due to the guide device only a significantly shorter section of the sawing cable could deflect, which is why the safety zone to be observed around the wire saw is considerably smaller.
    Another particular advantage of the mobile wire saw according to the invention is that the sawing cable does not have to be opened in order to guide it through a workpiece.
    In the context of the invention, the changing device for attachment to the mobile carrier device may be a mounting plate, which corresponds to a quick coupler on the carrier device.
    In a particularly preferred embodiment of the invention, it is provided that the mobile wire saw has at least one device for changing the spatial orientation of the saw unit, which comprises the guide device and the sawing cable.
    This feature and its advantageous developments can also be provided independently that the wire saw has a changing device for attachment to a mobile support device. Thus, it is possible by the mobile wire saw according to the invention that horizontal, vertical and oblique cuts can be made very fine. Spatial alignment of the saw unit may occur during operation of the mobile wire saw, i. while the saw wire is driven, be changed
    In particular, it can be provided that the saw unit is tiltably mounted about an axis extending across the width of the guide means (= cutting width), wherein the means for changing the spatial orientation comprises means for tilting the .Sägeaggregates, in particular at least one tilt cylinder. Alternatively or additionally, it may be provided that the saw unit is pivotally mounted about an axis over the height of the guide means {= cutting height), wherein the means for changing the spatial orientation comprises means for pivoting the saw unit. Alternatively or in addition, it may be provided that the wire saw " go out " can be, i. that the distance between the saw unit and the changing device is changeable. In this embodiment, the means for changing the spatial orientation comprises means for varying the distance between the saw unit and the changing device. Alternatively or additionally, it may be provided that the saw unit is rotatably mounted about an axis extending substantially perpendicular to the spatial extent of the guide means axis, wherein the means for changing the spatial orientation comprises means for rotating the saw unit. • * * * * * «*« * * ** * φ * I * * * * * Μ ·· 4 · «♦ · * · I» * # * * *
    In a particularly preferred embodiment of the invention. provided that the spatial extent of the saw unit during operation of the mobile wire saw, i. while the sawing wire is driven, is changeable. This feature and its advantageous developments can also be provided independently that the wire saw has a changing device for attachment to a mobile support device. Thus, the cutting width and / or the cutting height of the saw unit can be changed not only when aligning the wire saw with respect to the workpiece to be cut but also during sawing. By changing the cutting height can be achieved in a particularly advantageous manner that the wire saw can work both on rope pressure and on cable. In addition, it can be achieved that the wire saw is compact while driving to the site and is enlarged only at the site.
    In an advantageous development, it is provided that the guide device has telescopic arms, on which deflection rollers, in which the sawing wire is guided, are arranged.
    In order to change the spatial extent of the sawing unit, wherein the sawing cable retains the desired rope tension, the wire saw according to the invention may further comprise a cable storage and a cable tensioner, which at least two pulleys, in which the sawing cable can be performed several times. The distance of these pulleys can be changed for example by telescopic arms. It can be provided that the cable tensioner and the rope store are formed from the same components. In particular, the cable storage or the cable tensioner contribute to the advantage that the sawing cable does not have to be opened.
    In a further preferred embodiment, the wire saw can have variable-length support means, in particular support cylinders. With this support means, the cable saws can be supported on the workpiece to be cut, whereby a relief of the support device, in particular of the carrier vehicle, is achieved.
    Advantageously, it can be provided that the drive and / or the at least one device for changing the spatial orientation of the wire saw can be controlled by radio and / or by cable. An operation by radio and / or by cable with control box to control from the cab of the host vehicle is possible within the scope of the invention. ,
    In the context of the invention, the drive may be a purely hydraulic drive or a purely electric drive or an electro-hydraulic drive. The drive can be arranged on the guide device of the wire saw according to the invention, for example above the cable store or in the region of the cable store. The drive does not necessarily have to be part of the wire saw per se within the scope of the invention, but may also be part of the carrier device.
    The mobile wire saw according to the invention can be made in various sizes, for example with a variable cutting width of 2 - 4 m and / or with an exemplary specified cutting depth of about 0.5 - 3m.
    Fields of application of the mobile wire saw according to the invention can be, for example, the following: Natural quarry: block dressing, dressing and formatting of ingots; - construction sites: concrete cutting work for foundations, beams, etc .; - Earthmoving: cutting free-field stones or boulders as an alternative to cutting and / or blasting in sensitive areas; - Metal foundries. Cutting slag blocks and scrap metal; - demolition companies: cutting concrete, masonry, metal, etc .;
    Other features and advantages of the invention will become apparent from the following description with reference to the accompanying drawings in which a preferred embodiment is shown.
    1 shows a stationary wire saw according to the prior art, FIG. 2 shows a wire saw according to the prior art, which can be brought to the workpiece, FIG. 3 shows a wire saw according to the invention in front view, FIG. 4 shows the wire saw from FIG in side view, Fig. 5, the wire saw of Figure 3 in bottom view,
    Fig. 6, the wire saw of Figure 3 in a perspective view from the front and Fig. 7, the wire saw of Figure 3 in a perspective view from behind.
    Fig. 1 shows a known stationary wire saw 1, in which two pulleys 24 are arranged vertically movable for the sawing cable 3 on a stationary frame. This wire saw has an unalterable cutting height and width and can only work on rope pressure. The workpiece W to be cut must be transported to the wire saw.
    Fig. 2 shows a known wire saw 1, which can be brought to the workpiece to be cut. In this wire saw 1, the sawing wire 3 is guided around a deflection roller 22 which is fixedly mounted on a railroad carriage 21. After arranging the wire saw lift a workpiece, the sawing cable 3 must be opened in order to be able to lead it through an extra hole in the workpiece. For comminuting the workpiece, the track car 21 is moved away on tracks 23 from the workpiece to exert the cable for sawing. When the railcar 21 has arrived at the end of the track 23 and the workpiece is not yet completely cut, then the wire saw must be turned off and the sawing wire 3 is opened and shortened. Subsequently, the track car 21 is moved again in the direction of the workpiece, the shortened sawing wire 3 is closed and it can only be started again sawing me.
    FIGS. 3 to 7 show a wire saw 1 with a saw unit 2. The wire saw 1 has a changing device 20 for attachment to a mobile carrier device, for example a carrier vehicle (not shown).
    The saw unit 2 on the front side of the wire saw 1 in use position comprises a diamond wire as a sawing cable 3 and a guide device for the sawing cable 3. The guide device for the sawing cable 3 has telescopic arms 4 variable in length as well as guide rollers 5 arranged on telescopic arms 4. The sawing cable 3 is also over a cable storage 6 out, which can also act as a cable tensioner 7 at the same time. In rope store 6 or cable tensioner 7, which may also comprise telescopic arms 8 and guide rollers 9 variable in length, the sawing cable may be performed multiple times. In the illustrated embodiment, a drive 10 is arranged for the sawing wire above the cable store 6.
    On the rear side in use position of the wire saw 1 are devices 11, 12, 13, 14 for changing 'the spatial orientation of the saw unit 2. A device 11 for changing the spatial orientation is a device 11 for tilting the saw unit 2 by one in the Fig. Horizontal axis, in the embodiment shown a tilt cylinder. Another device 12 for changing the spatial orientation is a device 12 for pivoting the saw unit .2 about an axis extending vertically in the figure. This device 12 may have pivotally mounted telescopic arms, which also has the function of a device 13 for changing the distance between the saw unit 2 and the changing device 20. Another device 14 for changing the spatial orientation is a device 14 for rotating the saw unit 2 by up to 360 °. In the field of mounting plate support cylinder 15 are provided.
    The use of a carrier vehicle according to the invention with the mobile wire saw 1 according to the invention can be represented for example as follows:.
    The mobile wire saw 1 is attached by means of quick coupler with hydraulic or mechanical locking to the anticipated carrier vehicle. The carrier vehicle moves to the workpiece, which is to be cut, where by means of the carrier vehicle, a coarse direction of the wire saw 1 is performed to the workpiece. If the coarse alignment is executed, the support cylinders 15 are extended to the workpiece. This achieves a relief of the carrier vehicle (no yielding of the hydraulic components by weight of the wire saw 1} and the wire saw 1 is free on the workpiece.
    Thereafter, via the provided either inside or outside the cab of the host vehicle control panel of the wire saw 1, the fine alignment of the wire saw 1 to the workpiece and the fine adjustment of the wire saw 1 executed. In this case, all movements of pivoting, tilting, turning, retraction or extension of the saw unit 2 and the changing of the cutting width and / or cutting height of the saw unit 2 are possible. When the fine alignment and the fine adjustment are performed, cutting can be started by cutting the workpiece with the diamond wire by supplying cooling water.
    The wire saw 1 according to the invention is designed so that regardless of the position in which the guide device for the sawing wire 3 is, the endless sawing wire 3 always has a clearly defined cable tension.
    This is achieved by means of cable storage 6 and cable tensioner 7. The mobile wire saw 1 is constructed so that the saw unit 2 on both rope pressure and on cable (this can still be plugged additional pulleys) can cut, which is particularly advantageous in the construction sector. The mobile wire saw 1 can be equipped with different rope diameters depending on the application.
    To the saw unit 2, only a downwardly open protective housing (not shown) may be arranged, which increases the reliability when tearing the Sägeseiles 3. The size of the housing may be variable in order to adapt to changing spatial extent of the guide device can.
    In contrast to conventional wire saws, in which a workpiece to be cut for dicing must either be raised or where a hole must be drilled in the workpiece to be cut through which the saw is then guided, the wire saw according to the invention has the advantage that neither the nor does the endless diamond wire need to be opened to insert it into a wellbore. The diamond wire of the wire saw according to the invention can be easily applied on site to the workpiece to be cut, whereby particularly fine cuts (not only horizontal or vertical but also oblique cuts) can be achieved.
    In summary, an embodiment of the invention can be represented as follows:
    A wire saw 1 has a saw unit 2, wherein the saw unit 2 has a sawing wire 3 provided in particular with diamond segments and a guide device for the sawing wire 3 and wherein the sawing wire 3 can be driven by a drive 10. The wire saw 1 has a changing device 20 for attachment to a mobile carrier device.
