Definitions

  • Japanese patent publication JP6146285 shows an apparatus for cutting out vertically between two vertical boreholes.
  • US patent US558483 shows an apparatus for wire cutting vertically down by means of the weight of the apparatus.
  • US patent US2050761 shows pulleys that move on tracks along rods 21 by means of a weight.
  • US2577545 shows pulleys that move along guides.
  • US454712 illustrates struts with pulleys that are driven downwards into guide holes using weights.
  • US1735012 shows a screw mechanism for guiding pulleys
  • JP5332034 shows pulleys that are moveable along guide rails.
  • the invention is a wire saw arranged to carry an endless diamond wire (w), comprising the following features:
  • the invention is a wire saw arranged to carry an endless diamond wire (w), which saw e.g. in rock.
  • the diamond wire (w) is arranged to run between two generally parallel guide liner pipes (1a, 1b), wherein each guide liner pipe (1a, 1b) is provided with a longitudinally extending wagon (2) with a motorized tractor (3) arranged to pull said wagon (2) along a guide rail (4) within said guide liner pipe (2a, 2b), please see Fig. 1 and Fig. 2 , wherein the working direction is indicated by the term "in”.
  • Each wagon (2) has the tractor (3) arranged in front in the working direction of the wire saw within the guide liner pipes (1a, 1b), please see Fig. 1 and Fig. 2 wherein the working direction is towards the left, respectively right in the drawings. The working direction is not changed, only the perspective is reversed in the two drawings.
  • Figure 1 there are formed four parallel boreholes wherein the guide liner pipe is shown in the two upper ones. The most suitable for the purpose is to cut out the bottom face first, between the two bottom holes, then lateral surfaces between right lower and right upper boreholes, lower left and upper left respectively, and finally cut between the two upper boreholes. Then the square core may be removed by blasting or cutting, and you are left with a tunnel with straight, smooth cut walls, bottom and ceiling. It may alternatively be formed shafts.
  • the guide liner pipes are used in pairs as shown in Fig. 1 and Fig. 2 .
  • the guide liner pipes are continuous throughout the borehole length. They may be composed of 6 meter lengths and joined to form the desired total length, with the slits (5) corresponding at every joint.
  • Each guide liner pipe comprises each its oppositely facing slit (5a, 5b) to allow said diamond wire (w) to run to an opposite of said guide liner pipes (1b, 1a), please see Fig. 1 and Fig. 2 , and wherein the diamond wire (w) is also indicated in Fig. 3 running out to one side through the slit (5). Note again that only a small portion of the guide liner pipe (1) is shown.
  • Each wagon is provided with a front wire wheel (6a, 6b) and a rear wire wheel (7a, 7b), please see Fig. 3 , arranged to guide said diamond wire (w) internally between themselves in each guide liner pipe (1a, 1b).
  • the diamond wire (w) (6a, 6b) runs from the first forward wire wheel (61, 6b) to an opposite of said front wire wheels (6b, 6a);
  • At least said two front wire wheels (6a, 6b) are driven by each its motor (8a, 8b) and arranged to drive said diamond wire (w) please see Fig.3 .
  • the diamond wire (w) runs in its return direction across between said guide liner pipes (1b, 1a) between the opposite rear wire wheel (7b) back to the rear wire wheel (7a).
  • Each wagon (2) comprises a telescoping extendable stem (9), each with a linear actuator (10) arranged to tighten the rear wire wheel (7a, 7b) in a rearwards direction relative to said front wire wheel (6a, 6b) in order to tighten the diamond wire (w).
  • the linear actuator (10) may be a hydraulic cylinder.
  • all motors in the wire saw may be of the hydraulic type, and the hydraulic pressure is supplied in hoses through the hook-on end of the guide liner pipes (1) for the wire saw, i.e. the surface of the rock shown in Fig. 1 , from where the guide liner pipes (1) are fed in.
  • the wire saw according to an embodiment of the invention has the guide rail (4) designed as a pitch rack rail and wherein the tractor (3) is provided with a motor (30) that drives a propulsion gear wheel (31) on the guide rail (4) and with one or more back support wheels (32) for keeping the gear wheel (31) stably against the guide rail (4).
  • the back support wheels (32) are arranged to run along an opposite face of the guide liner pipe (1) relative to the guide rail (4).
  • the slit (5) may be on a lateral face of the guide liner pipe (1)
  • the guide rail (4) may be along the top of the guide liner pipe (1)
  • the back support wheels (32) run along the lower portion of the guide liner pipe (1). In this way one may avoid interference between the rails, wire, slit and wheels.
  • the wire saw according to the invention may have the back support wheels (32) arranged to run along two opposite faces of the guide liner pipe (1) relative to the guide rail (4) so as for forming corners of a triangle in a cross section of the guide liner pipe.
  • the back support wheels (32) may be arranged to run along one or more auxiliary guide rails (42) arranged in the guide liner pipe (1), please see Fig. 5 .
  • the wire saw according to the invention is such that the guide liner pipes (1a, 1b) are arranged to be inserted into each one of generally parallel drilled holes in rock, for a section between the guide liner pipes to be sawed out. It is also possible to arrange the guide liner pipe of wire saw in drilled holes in concrete structures, etc. in order to make sections.
  • the wire saw according to the invention is arranged so that the guide liner pipes (1a, 1b) are arranged in generally horizontally drilled holes.
  • a significant advantage of using pair-wise parallel horizontally drilled holes is that one is capable of making a horizontal section (between boreholes at the same elevation) and thus horizontal tunnels with the apparatus. This prevents slack on the wire and thus one may achieve a flat bottom and a flat roof in the tunnel. Thus one may achieve particularly even floor in the tunnel so that it becomes easy to arrange a runway or railway for which there are strict requirements with regard to the evenness of the substrate.
  • the guide liner pipes are arranged in pairs of parallel drilled holes to form a cut out hole with polygonal cross-section, e.g. rectangular, triangular, pentagonal, hexagonal.
  • the tractors (3) are arranged to be controlled at individual speed rates. It is usually desirable to allow the tractors run parallelly in order to make the diamond wire run the shortest distance between boreholes.
  • the drilled holes may be straight if you want a straight tunnel (or shaft).
  • the drilled holes may have a curvature to drill a curved tunnel or shaft.
  • the wire saw may be remotely controlled wherein the motors are operated via hydraulic hoses so that the operator may stay outside the drill area. It may therefore be so that the wire saw may be operated under water or in places where an operator, due to health and safety considerations, shall not stay e.g. for a toxic or radioactive area.
  • the wire saw according to the invention may have guide liner pipes (1a, 1b) arranged to be carried in a structural support frame on either sides of an object subject to a cut, for the sawing of a section between the guide liner pipes.
  • guide liner pipes (1a, 1b)
  • the guide pipes of the wire saw may be put on either sides of a pillar or a pipe, to cut it off in sections e.g. such as on land, above water or under water, e.g. to cut down concrete platforms, pipelines or the similar.
