Definitions
- the present invention refers to an apparatus for the axial movement of piping or the like, particularly useful during steps of salvaging from wells or tanks, or during the reverse step of laying in-depth, of piping and/or motor pumps.
- reference will likewise be made to two specific applications of the present invention, in particular to the hoisting and to the laying, in a vertical direction with respect to the ground, of piping. More specifically, it will be made reference to the field of submersible pumps used to extract water, etc., from wells and/or tanks.
- the present invention could apply to all those cases in which it is necessary to move piping elements or the like according to an axial direction thereof, anyhow tilted (or not tilted) with respect to the ground.
- such submersible pumps are lowered in-depth into the well and connected to the surface by piping for water extraction.
- the assembly of the pump and of the piping connected thereto may reach markedly elevated weight values, thereby making in the first instance a laying and then a subsequent salvage of the pump itself difficult.
- the laying in-depth and the salvaging of submersible motor pumps are generally carried out by means of a system manually operated by one or more operators.
- a (nylon or steel) cable or rope is present, having one end thereof connected to the body of the pump and through which the latter is lowered and then salvaged.
- the cable is reeled out and then reeled in by means of a manually (foot-) operated (pedal) winch.
- a mechanical arm is used, placed e.g. on a heavy motor vehicle.
- a first drawback concerns their limited applicability, owing to the maximum weight bearable by the cable.

- Figure 1 generally shows a first embodiment of the apparatus 1 according to the present invention, specifically adapted to carry out piping salvage steps.
- a piping or pipe 2 previously lowered in a hole 3 (e.g., a well) on the ground 4, needs extracting to be salvaged upon completion of the job.
- the apparatus 1 comprises a frame 5, firmly resting on the ground 4 by means of feet 6.
- a moving assembly 10 To the frame 5, first of all there is rigidly connected a moving assembly 10, more evident in the next Figure 2.
- the moving assembly 10 in turn comprises a top hoisting element 11, rigidly fixed onto the frame 5.
- a movable hoisting element 13 On said guides there may slide a movable hoisting element 13, e.g., mounted on gears or wheels 14.
- the two hoisting elements 11 and 13 are mounted in a manner such as to be perfectly aligned therebetween.
- the movable hoisting element 13 is driven by means of an electric motor 15 acting on a connecting rod system 16, in a manner such as to describe a reciprocating motion between a bottom dead center BDC and a top dead center TDC.
- a hydraulic drive system using, e.g., a pair of rams 17, as it is evident in Figure
- the top 11 and movable 13 hoisting elements have, apart from the presence of the gears 14, the same structure that will be illustrated with regard to the next figures.
- the hoisting elements are made in the form of a boxed body, comprising a passage hole 20 for the piping 2 to be moved.
- the hoisting elements have a wall portion 21, preferably of a rounded or semi-cylindrical shape, onto which there may rest a corresponding portion of the pipe 2.
- a wall 21 has a surface exhibiting a high friction coefficient or machined in a manner such as to have knurls or toothings apt to mesh to the external wall of the pipe 2.
- the hoisting element further comprises a tightening device substantially made of a roll element 22 having a globe-shaped contour.
- the surface of the roll 22 is it also preferably made from material exhibiting a high friction coefficient or machined so as to have knurls or toothings apt to mesh to the external wall of the pipe 2.
- the roll 22 is integral to a shaft 23 that is mounted on a pair of gears 24.
- the gears 24 are coupled to two linear racks 25, and movable therealong.
- the racks 25 are integral to the boxed body and tilted with respect to a horizontal working plane and to the pipe 2 to be moved, as it is evident in Figure 6.
- the shaft 23 can slide inside a pair of guide slots 26 obtained on the lateral sides of the body of the hoisting element.
- the slots 26 are parallel to the sliding racks 25.
- the operation of the individual hoisting element depends on its relative motion with respect to the piping 2 inserted therein.
- the roll 22 which anyhow contacts the piping 2
- the roll 22 tends to rotate in the sense indicated by the arrow F3 and then to move along the rack in the direction of the pipe 2 itself.
- the pipe is held constrained between the wall 21 of the hoisting element and the surface of the roll 22, making a self- tightening mechanism.
- the roll 22 tends to rotate in the sense indicated by the arrow F6 and then to move along the rack in an opposite direction with respect to the pipe 2 itself.
- FIGS 8 A to 8D illustrate a mode of employ of the apparatus according to the present invention.
- the piping is hoisted by a pair of hoisting elements 11, 13.
- said piping usually consist of different sections, connected thereamong by joints, ring nuts or the like, anyhow removable.
- the apparatus of the present invention provides a third top hoisting element 50.
- the element 50 is structurally identical to the other ones, and it is mounted integrally to the frame 5, at a predetermined distance with respect to the moving assembly 10 and to the ground.
- the piping 2, during the ascent, is threaded also through the through hole of said top element 50, entailing no hindrance whatsoever to the hoisting action.
- the distance from ground of the top element 50 is such as to allow an operator to reach the joint 51 for the disassembling ( Figure 8C).
- a control (apparatus starting/stopping) system should be provided to allow each time the disassembling of the pipe sections.
- the top element 50 could be provided with a release 60, illustrated in the next Figures 9 A, 9B and 9C.
- the top element 50 comprises a system of levers 61, 62 that, actuated e.g. by traction of a string 63, drag a pair of racks 65, coupled to the gears.
- the racks 65 move in the direction of the arrow F31 , dragging the roll that will rotate in the sense of the arrow F32, moving away from the pipe 2.
- the operator could freely extract the pipe from the bottom.
- a first embodiment of the apparatus 1 according to the present invention specifically contrived to operate according to a hoisting mode for the salvage of piping elements 2 and the like.
- a second embodiment of the apparatus 1 according to the present invention envisaging design variants particularly suitable for carrying out the steps of in-depth ground laying of piping 2 and the like.
- the operation principle of the apparatus 1 is based on the relative motion between the hoisting elements 11 and 13, suitably modified, and the piping 2 inserted therein.
- a first constructive variant of said second embodiment provides that a control bar 40 be slidably connected to the moving assembly 10.
- a slidable connection may be attained, e.g., via the slidable coupling of suitable pins, integral to the frame 5, inside guides obtained on the body of the control bar 40.
- Such a control bar 40 may thus be translated vertically and assume two extreme positions, corresponding to two different states, i.e. a first top position A and a second bottom position B.
- the triggering is produced by the interaction of suitable intercepting elements obtained on the control bar 40 and on the moving assembly 10, with corresponding actuation mechanisms arranged on the hoisting elements 11 and 13.
- the hoisting elements 11 and 13 are otherwise structurally analogous to those provided for the hoisting of the piping 2.
- Said actuation mechanisms may be mechanical and electromechanical. They comprise a system of levers 41 acting on a system of arms 43, rods 44 and racks 46, articulated and controlled so as to reciprocatingly move the rolls 22, mounted on the hoisting elements 11 and 13, near to or away from the piping 2.
- actuation mechanisms may be mechanical and electromechanical. They comprise a system of levers 41 acting on a system of arms 43, rods 44 and racks 46, articulated and controlled so as to reciprocatingly move the rolls 22, mounted on the hoisting elements 11 and 13, near to or away from the piping 2.
- the tightening condition of the piping 10 by means of a first hoisting element should take place in advance with respect to the combined releasing of the hold onto the piping 2 by means of a second hoisting element.
- the moving elements 1 1 and 13 are provided with a lever 41, projecting from the boxed body, lever that is moved when it contacts one of said intercepting elements.
- Said intercepting elements may be tabs 42 A, 42B and 42C integral to the control bar 40, or projections 42D integral to the frame 5.
- the lever 41 is rigidly connected to an arm 43; at the respective ends of the latter, two respective rods 44 are hinged, e.g., with a pin joint. Each rod 44 of said pair is hinged, at the opposite end thereof, to a respective rack 46. Topwise, each of said racks is coupled to a respective gear 24 of the hoisting elements 11 and 13.
- the configuration of the articulation deriving from the connection of the arm 43, the rods 44 and the racks 46 is determined by pins 45, located at the articulations of the rods 44 to the arm 43.
- Said pins 45 are actuated by a suitable control system, e.g. by means of actuators 47 employing photoelectric detection position transducers.
- the pins 45 are selectively extractable from respective recesses and, according to whether in the extracted position are found above or below said articulations, they constrain each respective articulation in a relevant configuration ensuring, respectively, the tightening of the rolls 22 onto the piping 2 or the releasing of the hold of the rolls 22 onto the piping 2 and, optionally, the mutual sliding.
- Such a movement cycle starts when the element 13 is moved, in the direction of the arrow G10, from its position corresponding to the top dead center TDC.
- the relative motion established between the element 13 and the piping 2 causes the rotation of the roll 22 of the element 13 according to the direction of the arrow
- the roll 22 of the fixed element 11 moves away, in the sense indicated by the arrow G12, so that a new laying cycle of the piping 2 can start with the descent of the element 13.
- deactivating means for the control bar 40 e.g., by moving away from the moving assembly 10, so that the use of the apparatus 1 for the salvage of piping may be converted at will, with a hoisting operation mode.
- the racks 46 meshing on the gears 24 merely support the rotations of the rolls 22 induced by the relative motion between piping 2 and elements 11 and 13.
- the projections 42D integral to the frame 5 may be designed so as to be selectively retractable.
- the apparatus according to the present invention may advantageously comprise a safety device for automatically interrupting the operation thereof when the entire pipe has been salvaged and the pump connected thereto has surfaced. Such a device could, e.g., act on a breaker to cut off power to the actuators and interrupt the operation of the apparatus.
- a further embodiment of the moving apparatus according to the present invention applicable in both operation modes, for the hoisting or for the laying of piping 2, provides that the electric motor, rather than via a connecting rod system 16, actuate the hoisting element 13 thanks to the coupling to a worm screw-nut screw system.
- the rotary motion transferred to a worm screw 71 by a motor 70, e.g. electric, is converted into linear motion of the hoisting element 13, inco ⁇ orating the threaded seat of a nut screw 72.
- a further embodiment of the moving apparatus 1 envisages the option of replacing the functionalities carried out by the control bar 40 for the synchronization of the control system, with detection devices 80, such as photoelectric cells, sending signals to suitable actuators, e.g., electromagnetic, such as to coordinate each stage of the lowering cycle of the piping 2 in order to ensure the perfect repeatability thereof.
- the roll element 22 having a substantially globe-shaped contour may be replaced by a different means for tightening the piping 2 to the wall portion 21 of the moving elements 11, 13. Referring to Figures 19 and 20, such a function is carried out by a tie block 90 having a recess 91 reproducing in negative the contour of the piping 2.
- the motion near to or away from with respect to the piping 2 is transmitted to the tie block 90 by the shaft 23, onto which the tie block 90 is pivoted, e.g. through the inte ⁇ osition of bearings.
- the orientation of the block 90 with respect to the piping 2 is kept thanks to the introduction of a second shaft 92, jointed to the block 90 and constrained, like the shaft 23, to slide inside the pair of guide slots 26.
- the tie block 90 is constrained to rigidly translate in the motion nearing to or away from with respect to the piping 2, so as to prevent a concomitant rotation thereof with respect to the hoisting element 11, 13, thereby ensuring at all times a perfect engagement of the recess 91 onto the piping 2.
- the surface of said recess 91 is it also preferably made from material exhibiting a high friction coefficient or machined so as to have knurls or toothings apt to mesh on the external wall of the piping 2. According to a further variant embodiment of the means for tightening the piping
- a tie block 93 cooperates with the roll 22 so that, with the carrying out of a joint tightening of the roll 22 and of the tie block 93 on said piping 2, it is concomitantly attained the result of an optimal adjustment of the hold of the roll 22 onto the piping 2.
- the tie block 93 carries out a function of controlling the entity of the force exerted by the roll 22 when holding, substantially limiting the stroke thereof so as to prevent squeezing phenomena on the piping 2.
- the tie block 93 and the roll 22 are connected with a connecting rod kinematic motion sized and configured so that the coming to hold of the tie block
- the tie block constrains the roll 22 so as to limit the compression exerted onto the piping 2 thereby.
- a rod kinematic motion provides that a first end 98 of an element 94 substantially shaped as a connecting rod be hinged in an eccentric position onto the roll 22, preferably onto the peripheral portion of one of the side surfaces of the roll
- the tie block 93 is constrained, by means of a plurality of pins 96, to move rigidly on guide slots 97 obtained on the boxed body of the hoisting elements.
- Said guide slots 97 have a tilt that is substantially defined by the positions assumed by the abovementioned second end 99 of the connecting rod 94, so that there be promoted a perfect sliding of the pins 96 therein, and no motion discontinuities be created.
- the tie block 93 inco ⁇ orates a recess 95 reproducing in negative the contour of said piping 2.
- the orientation of the block 93 with respect to the piping 2 is kept such as to anyhow ensure a perfect engagement of the recess 95 on the piping 2.
- the joint hold of the tie block 93 and of the roll 22 onto the piping 2 provides a greater reliability to the apparatus.
- the present invention was hereto disclosed according to a preferred embodiment thereof, given by way of a non-limiting example. It is understood that other embodiments of the invention may be envisaged, all however falling within the protective scope thereof, as defined by the appended claims.
