Definitions

  • the invention relates to a safety switching system for a equipped with clamping wedges and clamping device which can be actuated by a flowing medium for holding and / or lowering or Lifting a tubing string that is used to drill a hole to support the rock and to manufacture it a conveyor line is lined.
  • One of the Device is a holding device (spider), with which a pipe string with the help of clamping wedges is held for screwing with another pipe.
  • a holding device for automatic control of the setting according to US-PS 2,545,177 the wedges used when reaching the desired position of the pipe string.
  • a single pipe is first placed on a pipe string with a Auxiliary elevator that takes the pipe from a pipe store, places it on the pipe string and holds during the screwing process. After completing the screwing with The auxiliary elevator becomes the pipe string located below the attached pipe removed and replaced by the second tensioner, an elevator. This is in essentially identical to the holding device and is from above over the first Free-standing pipe, already screwed to the pipe string, pushed up until its clamping wedges reach the prescribed position on the pipe. Then his wedges set.
  • the invention has for its object a safety switching system of the aforementioned To create genus that is protected inside a tensioning device, no external is exposed to mechanical influences and excludes incorrect switching.
  • the Invention for solving this problem is characterized in that on the wedge holder A switching cam for a safety switching valve is attached to the tensioner arranged of the tensioning device and of the switching cam movable with the tensioning wedge holder can be actuated when the clamping wedges are in their correct clamping position on the pipe string take in.
  • the switching cam preferably has an ramp, a ramp and an intermediate vertical button located on and is from a contact wheel of the switching valve traversable.
  • the length of the button is determined by the diameter differences between the largest and the smallest of the pipes to be clamped correctly with the tensioning device.
  • the safety valve of one device is connected upstream of the control valve for actuating the working cylinder for clamping the wedges of the other device.
  • a short-circuit switch for bypassing the safety switch is provided for each clamping device. This switch is actuated in order to be able to initiate a tensioning process on the first pipe of a pipe string to be formed.
  • the individual components of the safety switching system are extraordinary Simplicity, standard training and housed within a tensioner, so that mechanical defects due to external influences cannot occur. switching errors are excluded with a high degree of certainty.
  • the safety switch 1 is fixedly connected with its housing 2 to a tensioning device and carries at the front end of a resilient holding arm 3 a feeler wheel 4 with which the surfaces 5, 6 and 7 of a switching cam 8 can be run over. Areas 5 and 7 are run-up areas for the feeler wheel, they go into button 6. Their length "1" is measured according to the difference in diameter between the largest and the smallest of the pipes to be clamped correctly with the tensioning device.
  • the cam 8 moves through its fixed connection with the clamping wedges of the tensioning device in the direction of the double arrow 9 and, when in active connection with the feeler wheel 4, allows them to reach their switching position via the surfaces 5 and 6. In the exemplary embodiment shown in FIG. 1, for reasons of better clarity, the safety switch is not shown in contact position with the switching cam 8.
  • a base body 10 with wedge surfaces 11 for example, two clamping wedges 12a and 12b are arranged such that they can be set vertically. Between these wedges there is an exciting section of a pipe string 13 to be grasped by setting the wedges.
  • the clamping wedges are fastened to wedge holders 14a and 14b and connected to an annular holding member 17 via force transmission lugs and connecting webs 16a, 16b.
  • the ring-shaped holding member is adjusted vertically via actuating units consisting of working cylinders and adjusting pistons 18a, 18b.
  • the actuators can be operated pneumatically as well as hydraulically. With 19, for example, a supply line for the work equipment is indicated. The supply is controlled via a working valve 20, the actuating lever 21 of which is mechanically connected to a control cylinder 22.
  • a protective cap 23 on the base body 10 largely closes off the entire device from the outside.
  • Figure 2 shows a part of the pipe string 13 with a pipe sleeve 24 within the still open clamping wedges.
  • the larger diameter of the pipe socket will set the Prevent tensioning wedges 12a and 12b up to their correct position.
  • the switch cam 8 will therefore not reach the touch wheel 4 of the safety switch 1. The same effect will adjust itself during a tensioning process with a pipe that is positioned correctly but is too large in diameter.
  • FIG. 1 A further incorrect position of the pipe string within a tensioning device is shown in FIG
  • the pipe string to be clamped has not reached the clamping wedges 12a and 12b.
  • the adjusting units 18a and 18b can therefore quickly the clamping wedges to the lower end of the Wedge surface 11 are lowered.
  • the switching cam 8 runs quickly past the feeler wheel 4, so that it is not an effective one to be triggered by the safety switch Switching process comes to the actuators of the second tensioning device, not shown Release releases. The same effect will be felt when clamping with a pipe adjust that is correctly positioned, but has a diameter that is too small.
  • FIG. 4 shows the pipe string in the prescribed clamping position within the Tensioning device.
  • the clamping wedges grip the pipe string below the connecting sleeve 24.
  • the Tensioning wedges can carry out the tensioning process with the help of the adjusting units 18a and 18b and assume their prescribed position within the clamping wedge surface 11.
  • With the Lowering of the clamping wedges 12a and 12b arrives on the holding member 14b of the clamping wedge Switch cam 8 in the area of the feeler wheel 4 and presses it against the housing 2 of the Safety switch.
  • the feeler wheel is in operative connection with the holding surface 6 of the Switch cam 8, which can not be moved further down, so that Touch wheel is constantly on the holding surface and the lock on the control cylinder of the not shown second picks up so that it can release the tubing.
  • a switch box 30 ( Figure 5) are those for the desired automatic process the operations on a drilling rig with a holding device (spider) and a sinker Elevator 32 included. They lead from the switch box corresponding connecting lines to the safety valves 1 and 101 on the holding device 31 and on the lowering and lifting device (elevator) 32 and the associated Control cylinders 22 and 122, which are each located on the devices.
  • the components of the entire security system should be based on the individual process steps Start of a bolting process are explained.
  • the lowering and Lifting device for the sake of simplicity with the usual designation "elevator” and the holding device provided with the usual name "Spider”.
  • the entire device is supplied with compressed air via the pressure source 40.
  • the spider can then be opened by pressing the actuating valve 42.
  • the Associated switching cam 8 leaves the switching position on the safety valve 1.
  • the work equipment to the actuating valve 142 is shut off and emptied.
  • the elevator can now move through the pipe string formed in the first position in the first two screwed pipes Lower.
  • the switch 42 is actuated again, as a result of which the control cylinder 22 is activated and the spider closes.
  • the safety switch 1 tensions again so that the elevator opens is released.
  • the valves 43 and 143 are safety valves which mutually prevent the control cylinders 22 and 122 from being actuated at the same time and the clamping wedges of the spider and the elevator being thereby able to be released simultaneously. Both valves can be shut off by shut-off valves 44 and 144 in order to be able to initiate a work process with the reception of the first tubes in the spider and elevator.
