Definitions

  • Such drill string grippers are used in particular in drilling rigs for earth or rock drilling, which approximately in the EP 1 832 710 B1 are described. These have a drilling device with drill carriage, along which a drill drive for drilling drill pipe elements of different diameters is slidably mounted. The drill pipe elements may be partially inserted into one another in a magazine near the drilling device. By means of a drill string gripper, drill pipe elements can be transported from the magazine to the drilling device and back again.
  • the drill pipe gripper can be controlled automatically by means of a drill string manipulator or operated by hand.
  • From the EP 2 713 003 B1 shows a rod handling system for drilling rigs, which has a collet with two pivoting swivel claws. By pivoting the pivoting claws inwardly, a drill string member is urged against a central locating roller, thus tensioning the drill string member.
  • the drive rollers are mounted on the two pivoting claws and rotationally driven via a respective rotary drive. By these drive rollers on the pivoting jaws, the drill string element can be driven in rotation in the cocked position. This is advantageous, for example, for screwing the tensioned drill pipe element to the drill string.
  • the swivel claws For receiving the rotary actuator, the swivel claws must be exposed and sufficiently dimensioned to prevent damage.
  • the known drill string gripper is only limitedly suitable for gripping a drill string element from a drill pipe magazine.
  • the arranged on the pivoting claws, above rotary actuators can be damaged in an intervention in a boom magazine.
  • the drill pipe elements must be placed in a drill pipe storage with a relatively large distance from each other, so that the drill string gripper can grip and clamp a single drill string element.
  • a large distance between the drill pipe elements reduces the capacity of a drill pipe magazine or leads to an increased size.
  • the invention has for its object to provide a drill string gripper, which is both compact and very versatile.
  • the drill string gripper according to the invention is characterized in that at least one drive roller for rotatably driving a drill string element is rotatably mounted on the thrust pawl, that a rotary drive is arranged on the thrust pawl and that the rotary drive is designed for rotationally driving the drive roller and is connected to the drive roller.
  • a basic idea of the invention is to provide a drive roller with a rotary drive at the central push claw in the case of a collet chuck with a compact construction and a fork-shaped collet housing.
  • a slim structure can be maintained at the protected in the forceps tines pivoting claw.
  • the rotary drive is arranged when engaging in a drill pipe magazine in a rearward and thus also protected position. The risk of damage such as a tilted engagement of the collet in a magazine is thereby significantly reduced.
  • the drill string gripper can also be used separately from a magazine, such as a screwing.
  • the drill string gripper according to the invention offers the additional advantage, in the case of the compact construction, that a tensioned drill string element can be driven in rotation via the drive roller on the push claw. This is about Screwing drill pipe elements with threaded sections or loosening a threaded connection possible.
  • the rotary drive can preferably be a hydraulic drive or an electric drive.
  • the rotary drive can be arranged in the tong housing.
  • a compact construction of the collet is achieved according to an embodiment of the drill string gripper in that at least one recess is formed on the pliers housing laterally on the push claw, wherein at least one side portion of the push claw in the clamping position and the retreat position is exposed, and that the rotary drive at the exposed Side region of the push claw is arranged. Since the rotary drive is attached to the rear push claw, a good protection is already achieved.
  • the rotary drive projects laterally out of the clamp housing.
  • the rotary drive is directed substantially parallel to the longitudinal axis of the drill string element to be clamped.
  • the recess provided in the invention in the region of the fork clearance, that the rotary drive can be fixedly attached to the side region or the edge of the push claw and is linearly movable with the push claw.
  • a particularly good torque transmission to a drill pipe element to be tensioned results according to a further embodiment of the invention in that two drive rollers are mounted on the push claw.
  • the two drive rollers are preferably arranged symmetrically to a center plane of the collet. As a result, a centric holding of the drill string element to be clamped is supported at the same time.
  • the at least one drive roller may be provided on its outer side with friction-increasing means, in particular with a groove structure or a friction-increasing coating.
  • the two drive rollers can in principle be driven by a single rotary drive with a corresponding gear stage.
  • a first drive roller it is particularly preferred for a first drive roller to have at least one drive roller a first rotary drive and a second drive roller with at least one second rotary drive are driven.
  • a particularly compact arrangement according to a further embodiment of the invention can be achieved in that the first rotary drive and the second rotary drive protrude from the tong housing on the same side.
  • a further increase in the torque to be transmitted is achieved in a further development according to the invention in that a drive roller is driven by two rotary drives, which are arranged on opposite side regions of the push claw. There is thus provided a double arrangement of rotary drives for a single drive roller. This makes it possible to arrange particularly compact small rotary drives, while still a high torque can be applied to the drive roller.
  • the at least one rotary drive has a substantially cylindrical housing with a center axis, which is directed substantially parallel to the axis of rotation of the drive roller.
  • the axis of rotation of the drive roller is coaxial with the drive shaft of the rotary drive.
  • a direct drive may be provided in which no gear stage is arranged between the exit shaft of the rotary drive and the drive roller.
  • a gear ratio or gear reduction between rotary drive and drive roller can be provided.
  • At least one contact roller is mounted on the pivoting jaws, which rests in the clamping position on the drill string element to be clamped.
  • the investment rollers are passive rollers, which are not driven directly rotating.
  • the rollers are arranged so that they protrude only slightly beyond the front surfaces of the pivoting jaws. The rollers considerably reduce the friction when turning the linkage.
  • the investment rollers can be rolling bearings.
  • the pliers housing has two mutually spaced side plates, which are interconnected via web elements.
  • the web elements are preferably arranged parallel to the longitudinal direction of the drill string element to be gripped.
  • the two plates can be the same.
  • a connection of the side plates on the web elements is preferably carried out via bolts.
  • a particularly accurate position gripping is achieved according to a development of the invention in that the lever mechanism is designed so that the extension of the push claw the pivoting jaws and the thrust pawl are moved evenly on a longitudinal axis of the drill string to exciting.
  • the current extension positions of the push claw and the two pivoting claws preferably always lie on a momentary contact circle, which always has the same center point. This center coincides with the application on a drill with the drilling axis.
  • the circle of contact is to be understood as the circle on which the contact points of the clamping claws lie with the outer surface of a cylindrical drill pipe element to be clamped.
  • two or more collets of a drill string gripper can simultaneously engage telescoping drill string members of different bore diameters without having to pre-adjust the chuck claws.
  • a single drill string element with a different outside diameter can then be gripped again using both collets.
  • This can preferably be achieved by arranging the axes of the pivot bearings of the pivot claws so that a connecting line between the two pivot axes intersects the longitudinal axis of the drill string element to be clamped.
  • the connecting line represents the shortest connection between the two pivot axes of the pivot bearing of the opposite pivoting jaws.
  • a secure gripping is further increased according to a preferred embodiment of the invention in that at least two collets are provided, which are arranged along a gripper frame.
