Definitions

  • the invention relates to a handling device for pipes, in which a mounting device is arranged both horizontally and vertically positionable and provided with a controllable Kleinm diagnosed for the pipes.
  • Such a handling device is used, in particular, to position, in the case of drilling facilities for the exploration or production of crude oil or natural gas, the pipes within which the drilling tool is handled and through which ultimately the product to be conveyed is passed.
  • the hitherto known handling devices can not yet meet all the requirements that are set within the scope of the diverse application requirements.
  • the object of the present invention is therefore to improve a handling device of the aforementioned type such that an increased quality of use in the handling and positioning of the tubes is provided. This object is achieved in that adjacent to the mounting device a centering device is arranged for the pipe to be held.
  • the tube is centered relative to a wellbore such that the longitudinal axis of the tube passes through the center of the wellbore.
  • the centering system also performs a stabilization of the positioning of the drill pipe, so that in particular the use of self-closing handling devices is supported, which after a lateral pushing on the drill pipe by mechanical contact with the drill pipe automatically in a closed position be transferred.
  • a provision of large actuating forces can be effected in that the centering device is designed hydraulically.
  • a convenient arrangement is provided by the fact that the centering device is supported by a drilling table.
  • a lowering or lifting of a composite of several individual tubes tubing is supported by the fact that two support means are arranged in the direction of a longitudinal axis of the carriage in succession on a carriage.
  • At least one of the support means is provided with a side door.
  • a reliable and robust centering function can be provided by providing the centering device with guide plates.
  • the centering device is provided with pivoting flaps as centering. A possible risk of accidents can be reduced by the fact that the flaps are locked in a swung-up positioning.
  • centering device has a split outer ring.
  • a proximity switch is used for at least one of the mounting devices.
  • a simple yet reliable and accurate control is achieved in that the traversing cylinder is equipped with a proportional directional valve.
  • a locking state of the mounting device can be monitored by providing at least one of the mounting devices with a pressure switch as a signaling device for a locking function.
  • FIG. 1 shows a view according to the viewing direction II in FIG. 1 for illustrating the position of the supply lines
  • FIG. 3 is a plan view of a centering device
  • Fig. 6 is another illustration of the centering device.
  • Fig. 7 is a perspective view of the centering device, with folded segment of the centering device.
  • FIG. 1 shows a perspective view of a handling system (1) for positioning drill pipes (2).
  • the handling system (1) has a first holding device (3) and a second holding device (4). According to the illustrated operating state, the first mounting device (3) acts on the drill pipe (2) and the second mounting device (4) is positioned in the horizontal direction next to the first mounting device (3).
  • the mounting devices (3, 4) have laterally and oppositely arranged support projections (5, 6), which are acted upon for vertical positioning of the mounting devices (3, 4) of connecting elements (7, 8), which are adapted to receive the TragvorSprünge (5 , 6) ring-like end segments (9, 10) and can be coupled with a lifting device, not shown.
  • the support means (3, 4) are mounted on a carriage (11) to facilitate horizontal positioning. Positioning takes place using a traversing cylinder (12), which is typically hydraulically formed.
  • Fig. L further shows a front connection (13) and a rear connection (14), a lateral multi-coupling (15) and a centering device (16).
  • the hydraulic centering device (16) is embedded in the drilling table directly under the carriage (11).
  • the centering device (16) has the task to center the drill pipe (2) on the center of the wellbore.
  • the centering is controlled as a function of the height positioning of the mounting device (3) and typically takes place only in two situations:
  • the mounting device (3) When pulling out the drill pipe (2), the mounting device (3) raises the whole pipe string as an elevator and moves upwards. In the upper end position, the drill pipe (2) is centered by a centering device. Then, the lower, empty support means (4) with open doors on the carriage (11) moves to the center of the borehole. The elevator (4) abuts against the drill pipe (2) and thereby closes automatically. Without centering, the drill pipe (2) could spring away and the closing of the elevator (4) is not reliably triggered.
  • the elevator (3) When inserting the drill pipe (2), the elevator (3) is set down with the pipe string. Shortly before placing the drill pipe (2) is centered by a centering device, so that the elevator (3) is positioned exactly on the center of the wellbore. As a result, the subsequent coupling and uncoupling of the elevator (3) is simplified and ship movements are compensated.
  • the centering device gives an opening signal to the controller to inform the operator of the condition.
  • the centering device has interchangeable guide plates with which different areas of pipe diameters can be centered.
  • the centering device can be opened for maintenance / lubrication and, if necessary, for centering larger pipe elements.>
  • the opened lid lock when opening mechanically for safety reasons to prevent a risk of jamming.
  • An outer ring of the centering device (16) is divided, so that the centering device (16) can be removed from the pipe string, if necessary.
  • An electrical proximity switch is used to signal the position of the elevator (3, 4) to the controller.
  • an electrical proximity switch sends a signal to the controller. The same applies to the rear parking position.
  • a displacement measuring system of the traversing cylinder (12) and a hydraulic control are used.
  • the Verfahrzylinder (12) is equipped with an electrical displacement measuring system. As a result, the current position of the carriage (11) is always known and in combination with the electrical proximity switches, the controller is also the position of the elevators (3, 4) known.
  • the traversing cylinder (12) is controlled by a proportional directional valve. As a result, a higher operating speed is possible together with the displacement measuring system, in particular a higher travel speed in combination with a slow start-up and braking.
  • An additional pressure switch is used to signal the elevator lock to the controller.
  • the Verfahrzylinder (12) extends a small carriage to the elevator (3, 4) on or uncouple.
  • the coupling is confirmed by a hydraulic pressure switch, which outputs an electrical signal to the controller.
  • An energy chain (17) is used to move the hydraulic hoses.
  • the hydraulic hoses are moved less and the durability increases.
  • Fig. 1 further shows a locking pin (18), a rear Mulitkupplung (19) and a display bar (20).
  • a locking cylinder (21), a locking bolt (22) and an oil flow divider (23) can be seen.
  • roller unit (24) a load eye (25) and a display device (26) which provides an optical feedback signal.
  • FIG. 2 shows a side view of the device according to FIG. 1 corresponding to viewing direction II in FIG. 1.
  • the element (30) supplies the supply of lubricants
  • the element (31) opens the locking cylinder (21)
  • the element (32) closes the mounting device (3, 4)
  • the element (33) opens the mounting device (3 , 4)
  • the element (34) the closing of the locking cylinder (21)
  • the element (35) provides the feedback signal.
  • the element (36) directs the air pressure to position the carriage (11) in the parking position, the element (37) cleaning air and the element (38) a return of the rolling unit (24) or a return of the support means (3, 4) ,
  • the element (39) is associated with the pressure of the flow divider for the roller unit (24) and the pressure for the positioning of the support means (3, 4).
  • the element (40) serves to return the cylinder and the element (41) transmits the pressure of the cylinder for the SCID system. All drawn in Fig. 2 elements (30-41) can be designed as coupling elements or bushings for associated hydraulic lines pneumatic or electrical lines.
  • FIG. 3 shows a plan view of the centering device (16) and FIG. 4 shows a cross section through the centering device (16) according to section line IV-IV in FIG. 3.
  • Fig. 5 shows a side view of the centering device (16) and Fig. 6 is a plan view of the centering device (16) with folded down flaps (42, 43).
  • Fig. 7 shows a perspective view of the centering device (16), in which the flap (42) is folded up.
  • the flaps (42, 43) form the centering elements of the centering device (16) which act on the drill pipe (2).
