Definitions

  • the present invention relates to apparatuses for installing, dismantling and servicing ducts, and preferably submerged ducts. Particularly, the present invention relates to an apparatus for separating flanged joints in tubular ducts.
  • the aim of the present invention is to provide an apparatus which allows a flanged joint in tubular ducts to be separated in a simple and reliable manner, and which allows the so-separated flanges to be re-used.
  • Another aim is to provide an apparatus which has the most simple and lightweight structure as possible, and which is easy to be adapted to different types of ducts.
  • the object of the present invention is an apparatus for separating a flanged joint in tubular ducts, said joint comprising a flange radially protruding from each end of each piece of a duct, said flanges being coupled by means of suitable clamping means;
  • said apparatus includes: a support frame able to be coupled to said joint and movable around said joint by means of suitable guiding and moving means, said means being arranged on a plane which is parallel to the plane of said joint; cutting means coupled to said support frame and movable along a radial direction with respect to the longitudinal axis of said duct, said cutting means being arranged with the cutting plane substantially coinciding with the plane of said joint.
  • said cutting means include a closed loop of diamond-edged cable comprising at least one transmission idler pulley and a motor-driven pulley.
  • Said idler pulley is movably mounted with respect to said support frame along a radial direction with respect to the longitudinal axis of said duct.
  • said support frame includes at least two members which are articulated to each other, said members being able to enclose more of a half of the perimeter of said joint and being provided with means for slidably guiding them on said joint.
  • the articulation of said members can include actuating means allowing said support frame to be coupled to said joint.
  • the means for moving said frame on said joint can include a toothed wheel cooperating with the clamping means for said joint and provided with actuating means.
  • Figure 1 shows a front elevation view of the apparatus according to the present invention
  • Figure 2 shows a rear elevation view of the apparatus of Figure 1 ;
  • Figure 3 is a left side elevation view of the apparatus of Figure 1 ;
  • Figure 4 is a right side elevation view of the apparatus of the invention as mounted to the joint of a duct;
  • FIGS. 5 to 8 are front elevation views of the installed device of Figure
  • reference numeral 1 denotes the support frame consisting of five members 101 , 201 , 301 , 401 and 501 which are, in the preferred embodiment, metal profiles connected to each other to form a "C" with an arrangement substantially corresponding to that of an octagon without three consecutive sides.
  • the first profiled member 101 has arranged thereon a roller 131 which is idle and rotatably mounted on a perpendicular axis to the plane identified by said support frame 1.
  • a roller 131 which is idle and rotatably mounted on a perpendicular axis to the plane identified by said support frame 1.
  • an eyelet 121 in which the hydraulic jack 1 1 1 is pivotally fitted, the end of the hydraulic jack opposite to that engaged with the eyelet 121 being connected to an arm 302.
  • Said arm 302 has arranged thereon the idler pulley 202 and the motor-driven pulley 102 driving the loop of diamond-edged cable 2, and the arm is pivotally connected, as better described hereinbelow, to the third profiled member 301 of the support frame 1 which is also provided with a roller 311 directed towards the interior of said frame 1.
  • the arm is provided with a roller 312.
  • the fourth profiled member 401 of said frame has mounted thereon a toothed wheel 41 1 which is spliced to a shaft 421 coupled to suitable driving means not shown in the figure (see Figure 2).
  • said member 401 has an eyelet 441 to which one end of the hydraulic jack 611 is pivotally coupled, while the other end of the hydraulic jack is connected to the eyelet of the articulated arm 601 which, in turn, is articulated to the eyelet 511 formed at the free end of the member 501 of the support frame 1.
  • the arm 601 has the roller 621 at the free end thereof.
  • FIG 2 there is shown the apparatus of the invention in rear elevation; like parts are referred to by like numerals.
  • the driving means 1 12 of the motor-driven pulley 102 such as the driving means 1 12 of the motor-driven pulley 102.
  • the toothed wheel 41 1 is driven by the gear motor 431 .
  • Figure 3 there is shown the apparatus of the invention in left side elevation with respect to that illustrated in Figure 1 ; also in this case, like parts are referred to by like numerals. It is to be noted that the toothed wheel 41 1 and both the motor-driven pulley 102 and the idler pulley 202 carrying the loop 2 of diamond-edged cable are arranged on the same plane.
  • FIG 4 the apparatus of the invention is shown after having being mounted to a flanged joint.
  • the duct piece 10 arranged on the support structure 20 has, at an end thereof, a flared portion 11 and a protruding radial flange 12 on which the apparatus according to the present invention is positioned.
  • the configuration of the rollers 31 1 and 621 allows the support structure to be guided on the flange 12.
  • the flange 12 has coupled thereto the flat cover 15 by means of the threaded rods 13 and the nuts 14; however, this cover 15, herein illustrated to graphically simplify the explanation of the operation of the apparatus of the invention which is given hereinbelow with reference to Figures 5 to 8, can be actually considered as equivalent to a flange radially protruding from a piece 16 provided with a flared portion 17 as shown in dashed lines in the figure. It is also to be pointed out that the toothed wheel 411 is positioned so as to cooperate with the threaded rods 13.
  • Figures 5 through 8 illustrate the operation of the apparatus according to the present invention. As already illustrated in Figure 4, the apparatus is positioned on the joint, in this case between a flat cover 15 and a duct piece 0.
  • the articulated arm 601 is contacted with the flange 12 shown in chained line in Figure 5. At this time, the whole support frame is guided on the flange 12 by rollers 131 , 31 1 and 621.
  • the threaded wheel 41 1 is contacting the threaded rod 13 which cooperates with the nuts 14 to allow the cover 15 to be clamped against the flange 12.
  • the body of the toothed wheel 411 is tapered in thickness towards its outer peripheral edge, and this allows the wheel to always easily cooperate with the stumps of the threaded rods 13 which have been cut by the diamond-edged cable 2.
  • protection means can be positioned at the sides of the diamond-edged cable in order to preserve the integrity of the flanges.
  • the support frame 1 can be constructed in different manners; in this case, a structure able to surround half of the circumference of the flange of the duct when in the open configuration is preferred. From one hand, this type of configuration makes the apparatus easy to be positioned, so that it can easily access the flanges of the ducts for which it has been projected.
  • the choice of using profiled members of substantially equal dimensions allows to simplify the manufacture of the structure from the design point of view. In general, a structure based on regular polygons allows for a good approximation to the circle, and it is less challenging than otherwise-shaped structures from the construction point of view.
  • the rollers are arranged on the support frame so as to be substantially equally spaced from each other.
  • the support frame will enclose a portion of not less than 120° of the circumference of the flange.
  • the idler pulley 202 when the idler pulley 202 is in its operative position, it will be substantially at one end of said support frame 1 , while the motor-driven pulley will be substantially at the centre of said frame. Consequently, the two pulleys 102, 202 are at a centre-to-centre distance from each other of not less than the diameter of said flange 12.
  • the hydraulic jacks 611 and 1 1 1 have been considered for respectively moving the articulated arm 601 and the arm 302 with the pulleys 102 and 202, it is to be understood that the means for effecting the swinging movements can be of other type, for example of the electromechanical type.
  • actuating means can be all controlled remotely, preferably by means of a control central unit operating through suitable electronic interface means.
