Definitions

  • the invention relates to a device for producing threaded connections between tubular bodies, consisting of a housing with a continuous axial opening, a radial cutout adapted to the outer diameter of the tube and a toothed ring which is rotatably arranged in the housing by means of a drive device and which is provided with a corresponding radial cutout and overrun cams carries with overrun curves, which are associated with an articulated clamping jaw with a gripping knife and at least one further rigid clamping jaw with a gripping knife as a counter-knife on a lever which increases the contact pressure.
  • a device for countering and breaking threaded connections between pipe bodies of pipe and drill strings and drilling tools for deep drilling uses a rotatable and a non-rotatable chuck, which together define a device main axis, to accommodate one of two pipe bodies used with mutually facing end thread areas, the one chuck being mounted in a bearing block which is fixedly supported on one end of a device frame and the other chuck is arranged on a support block.
  • This device is only stationary and cannot be used on a derrick.
  • US-A-4 297 922 shows a device for producing threaded connections between tubular bodies, which consists of a housing with an axial opening and a radial cutout adapted to the outer diameter of the tube. A rotatable gear rim with a corresponding radial cut-out is located within the housing. An articulated clamping jaw with a gripping knife is arranged on a lever element which increases the contact pressure. The movable clamping jaw can be exchanged for a rigid clamping jaw by repositioning, in order to be able to make a screwing process reversible.
  • this device is not suitable for the transmission of high torques and thus not for countering and breaking drill rods, because the gripping knives are fastened to simple jaw carriers, so that large forces cannot be transmitted.
  • the invention is based on the object of also creating a hand-guided, open pliers for screwing on drill rods for use on the drilling rig, with which the necessary very high torques, which must be several times higher than in the previously known constructions, can be applied despite the light version of the pliers.
  • the solution according to the invention is characterized in that the rigid gripping knife attached to the articulated clamping jaws is assigned two rigid gripping knives as counter-holding knives, with the articulated clamping jaws carrying the gripping knife and the rigid gripping knife carrying the neighboring jaw seen in the direction of rotation for reversibility of the clamping movement in a release movement
  • the jaws are interchangeable by repositioning and the movable jaw is designed as a one-armed force-boosting lever with a pressure roller that can be actuated by the run-up curve, and the gripping knives and jaws are fastened to a solid crescent-shaped jaw carrier and that the movable gripping knife is convex.
  • each drill pipe is securely gripped at three points in connection with two rigid gripping knives.
  • the pipe detection system at three points ensures the processing of drill pipes with significantly different diameters.
  • housing-fixed stops are provided for the overrun cams carrying the overrun curves.
  • stop bolts are used, which are assigned to the overrun cams so that each cam can lay its rear surface against a stop bolt as soon as the pressure roller of the movable clamping jaw has reached the top end of an overrun curve.
  • the movable one is against the opposite one rigid jaw replaced. Both jaws as well as the third gripping knife are carried by a sickle-shaped solid jaw carrier known per se, which is connected to the rotor disks. After changing the position of the movable jaw with the rigid, the direction of rotation of the ring gear can be reversed, so that when the pipe section in question is securely gripped again, it can be rotated counter to its screwing direction and its connection with the adjacent rod section can be broken.
  • the device according to the invention is also suitable for the actual screwing process, for "spinning".
  • the screwing rotations can be carried out in addition to countering and in the opposite direction from breaking to complete loosening.
  • a device is provided whose properties, namely low mass, open system and the ability not only to counter or break a screw connection, but also to carry out the entire screw movement, allow use on a derrick and thus a considerable saving of time.
  • the rigid gripping knife 5 is arranged on the end of the crescent-shaped jaw support 3 opposite the movable gripping knife 4. It is inserted into a fixed jaw 15, which in turn is firmly connected to the rotor disks 18 and 19 via a bolt 17.
  • a fixed stop 15 includes a return stop 20 which is connected to the rigid jaw by pins 21 in a form-fitting manner. In the example shown, the return stop limits the rotation of the rotor ring 1 in a direction of rotation which is directed in the opposite direction to the arrow 10.
  • the return stop can rest against the run-up curve 22 of the second run-up cam 23 or, after having been plugged into the position of the movable clamping jaw, against the run-up curve 11 and turn the system of the rotor ring with rotor disks back into the starting position.
  • the third, likewise rigid gripping jaw 6 is fastened in the middle of the jaw carrier 3. This results in a force attack at three points on a drill pipe. Due to the movable mounting of the convex-shaped gripping knife 4 in the movable clamping jaw 7 designed as a one-armed lever, drill rods of different diameters can be gripped, screwed and countered or a screw connection broken with sufficient security.
  • the positions of a 5 7/8 "and a 6 1/2" drill pipe 31 and 30 are indicated in broken lines. In the example shown, the 5 7/8 "tube 31 is the smallest size that can be detected by the device.
  • the pressure roller 9 is just being caught by the run-up curve 11 with its radially inner end.
  • stop bolts 24 and, in the opposite direction of rotation, 25 serve. Against these stop bolts, the run-up cams 12 and 23 can rest with their rear ends.
  • the rotor ring 1 is bordered on both sides by slide guide rings 26 and 27, with which it can slide in circumferential grooves 28 and 29 of the rotor disks 18 and 19.
  • the radial cutouts of the housing, rotor disks and rotor ring are brought into line by rotating the rotor ring.
  • the suspended device can then be pivoted by hand onto a pipe until the rigid gripping knives 5 and 6 come into contact.
  • the two rigid knives are offset by 90 ° to each other and thus ensure that the device is centered on the pipe or drill pipe.
  • the rotor ring 1 is rotated in the direction of the arrow 10.
  • the pressure roller 9 of the movable clamping jaw 7 runs onto the run-up curve 11 of the run-up cam 12 and pivots the gripping knife 4 against the drill rod 31.
  • the predetermined clamping value the is necessary to transfer the counter or breaking torque to a screw connection, the actual screwing or unscrewing process begins.
  • the movement arrow 10 shows the direction of rotation for breaking a screw connection with subsequent unscrewing process.
  • the movable clamping jaw 7 and the fixed clamping jaw 15 are exchanged for one another beforehand.
  • the bolt 8b thus becomes the pivot bolt for the jaws 7, while the previous pivot bolt 8a engages through the fixed jaws 15.
  • the return springs 13 each ensure that after a corresponding return rotation of the rotor ring, the contact pressure of the gripping knife 4 is completely removed and the clamping jaws 7 is pivoted radially outwards.
  • the arrangement of the convex gripping knife 4 on the jaw 7 is selected so that the clamping force is increased by the position of the jaw.
  • the position of the pressure roller compensates for the loss of tension force that the system experiences when it works at the maximum allowable dimension of the drill pipe connection.
  • the lever arm between the pivot pin 8a and the pressure roller 9 becomes larger; the effective lever arm for increasing the clamping force is reduced.
  • the force application point on the linkage to be screwed lies between the center of gravity of the clamping jaw and the center of the entire system.
  • the device according to the invention can be guided by hand and is nevertheless able to apply the highest torques which are necessary for countering or breaking the screw connections of drill rods.
  • the ratio of the maximum torques to the weight of the device is much larger than in the previously known designs.
