Definitions

  • the present invention relates to a support for saws for rails, of the type which can be coupled directly to the rail.
  • the sector for application of the present invention is that of cutting rails which constitute railway lines.
  • rails are cut using a torch (normally of the oxy-propane type).
  • the support has a rigid structure which can be coupled, using coupling means, directly under the base of the rail.
  • the support also has a seat designed to receive an engagement element integral with the saw.
  • the technical need which forms the basis of the present invention is to provide a support for saws for rails which overcomes the above-mentioned disadvantages.
  • the technical need of the present invention is to provide a support for saws for rails which can be fitted in any operating conditions.
  • the numeral 1 denotes as a whole a support for saws for rails made in accordance with the present invention.
  • Figure 1 the support 1 is illustrated applied to a conventional rail 2 which has a base 3 and a head 4.
  • the support 1 comprises first a rigid structure 5 with a main direction of extension which, when the support 1 is coupled to the rail 2, is transversal (perpendicular in the accompanying drawings) to the direction in which the rail 2 extends.
  • the rigid structure 5 has an upper surface 6 and a lower surface 7 and can be at least partly attached to the rail 2.
  • the lower surface 7 of the rigid structure 5 can be attached to the rail 2 head 4.
  • the support 1 also has coupling means 8 mounted on the rigid structure 5, which are designed to couple the support 1 to the rail 2.
  • the coupling means 8 are operatively attached to the lower surface 7 of the rigid structure 5.
  • the coupling means 8 comprise at least one coupling element 9 mobile from an engage position in which it locks the support 1 to the rail 2 (illustrated with a continuous line in Figure 1), to a release position in which the support 1 can either be attached to or removed from the rail 2 (illustrated with a dashed line in Figure 1).
  • the rigid structure 5 has a first seat 10 designed to receive one side of the rail 2 head 4.
  • the coupling element 9 comprises a screw 11 tightened in a first threaded through-hole 12 made in the rigid structure 5 and having a first end 13 with a clamping head 14 designed to press against the rail head 4 to keep it clamped in the first seat 10, and a second end 15 with means 16 for tightening the screw 11 (a conventional handle in the accompanying drawings).
  • the coupling element 9 is mobile along a direction in a vertical plane and angled upwards ( Figure 1).
  • the rigid structure 5 has a central portion 17 for connection to the rail 2 and a first and a second end portions 18, 19 which, in practice, are positioned lower than the central portion 17.
  • the fixing means 20 comprise a seat 21 and a locking part 22 operating in the seat 21.
  • the seat 21 is designed to receive a first engagement element (not illustrated) shaped to match it, located on the saw.
  • the locking part 22 can in turn be moved between a free insertion position in which the first engagement element can be inserted in and removed from the seat 21, and a retaining position in which insertion of the first engagement element in the seat 21 and its removal from the latter are inhibited.
  • the seat 21 consists of a cylindrical compartment extending, in practice, substantially parallel with the direction in which the rail 2 extends.
  • the seat 21 and the locking part 22 allow the first engagement element to be locked in a plurality of separate positions, each moved relative to the others along the direction in which the axis of the seat 21 extends.
  • the locking part 22 consists of a threaded element 23 which extends in a straight line, fitted in a second through-hole 24 made in a side wall 25 of the seat 21, and having a first end 13 which can be inserted in the seat 21 to lock the first engagement element, and a second end 15 to which a tightening head 26 is attached 26.
  • the seat 21 has a projecting U-shaped flange 27, also with a hole in it.
  • the second, threaded through-hole 24 is made in the U-shaped flange 27, whilst there is a smooth hole 28 in the side wall 25 of the seat 21.
  • the fixing means 20 also comprise a safety element 29 for securely holding the saw away from the rail 2 to be cut.
  • the safety element 29 comprises a second seat 30 designed to receive a second engagement element integral with the saw, and a coupler 31 mobile from a locking position, in which it can act on the second engagement element to lock it in the second seat 30, to a release position, in which it allows the second engagement element to be inserted in and removed from the second seat 30.
  • the coupler 31 has, towards the outside of the second seat (towards the top in Figure 1), a tapered configuration, so that a downward pressure exerted by the second engagement element causes the coupler 31 to move from the locking position to the release position with consequent insertion of the second engagement element in the second seat 30.
  • the coupler 31 has a grip 32 which allows it to be moved manually from the locking position to the release position when the saw has to be released.
  • the present invention refers not just to the support 1 as such, but also to a saw for rails which comprises it.
  • the saw for rails comprises a main body with a cutting blade, which can operate in a vertical cutting plane, and a least a first engagement element extending transversally to the blade operating plane.
  • the body may also comprise at least a second engagement element.
  • the body is, in practice, mobile from an operating position in which the blade is at the rail 2 and can cut the rail 2, and a position outside the dimensions, turned about the axis of rotation defined by the fixing means 20.
  • the engagement element may be rigidly fixed to the body and rotatably attached to the support 1, or the engagement element may be rotatably fixed to the body and rigidly attached to the support 1.
  • the present invention brings important advantages.
  • the saw can be fitted in any operating conditions, in particular at sections of rail where the saw cannot be fixed to the base of the rail.
