For by the tubing junk of card or eligible for repair sleeve pipe, when cannot process with additive method, often adopt the method process of cutting, wherein mechanical type internal cutter is a kind of special tool from the inner cutting pipe of down-hole string.Mechanical type internal cutter is from sleeve pipe, oil pipe, the inner a kind of mechanical type cutting tool carrying out cutting of drilling rod.
Existing machine cuts cutter mainly relies on the rotating speed provided by rotating disk to produce cutting speed cutting tubing string, and in the process of cutting tubing string, cutter not only produces radial motion, and produces axially-movable.
Summary of the invention
The utility model is intended to overcome existing machinery cutter and rotating disk can only be relied on to provide the limitation of rotary cutting power, provides a kind of hydro powered that utilizes and produces the mechanical internal cutter rotating and carry out cutting.Its technical scheme adopted is as follows:
Waterpower assists cutting type internal cutter, comprises top connection, connecting axle, cylindrical shell, turbine bearing mounting base, bearing, turbine, feed nut, nut lock rationed marketing, swivel feeding cover, pedestal stop pin, feeding connecting rod, swivelling tool-holder, cutter, tool feeding pedestal, connecting pin, thrust bearing, swivelling tool-holder bearing support, bottom link, link stop pin, lower contact.Described top connection is arranged on upper tool part, for jointed rod, described connecting axle is for connecting top connection and lower contact, and for supporting each part in cylindrical shell, described turbine bearing mounting base is arranged on inner barrel, for installing bearing, described tool feeding pedestal is connected in swivel feeding by pedestal stop pin and puts, described feeding connecting rod is connected with tool feeding pedestal and cutter by connecting pin, described swivelling tool-holder and connecting axle coaxially assemble, and cutter are installed thereon, described thrust bearing and swivelling tool-holder keep in touch, and be arranged on swivelling tool-holder bearing support, described bottom link is arranged on lower contact by link stop pin, and connect top connection by connecting axle.Moving axially of tool feeding pedestal drives feeding connecting rod to open, thus drive cutter to move radially along the chute generation of swivelling tool-holder, meanwhile, swivel feeding cover with tool feeding pedestal be rotated through feeding connecting rod driven rotary knife rest and cutter rotate, cutter produce rotation and radial feed motion simultaneously, thus start to cut tubing string, until tubing string is cut off, when stopping the circulating of circulation fluid, cutter still can not be regained, and are namely taken out by tubing string more than cut place by this instrument this moment.
Described turbine is arranged between bearing, and is connected by the feather key on it with swivel feeding cover, and described feed nut is cemented on cylindrical shell by nut lock rationed marketing, and assembles with swivel feeding external threading.Logical circulation fluid drives turbine 6 to rotate, and is rotated by feather key driven rotary feeding cover 9, relatively to rotate, thus produce axial displacement because feed nut 7 and swivel feeding overlaps 9, and swivel feeding overlaps 9 carry its tools feeding pedestals 14 and rotates also generation simultaneously and move axially.
The utility model tool has the following advantages: utilize hydro powered to cut tubing string, have very high cutting efficiency, when being used in combination with the method utilizing drill string rotating to cut, can further improve the efficiency of cutting tubing string, and completing the extraction of tubing string after dicing.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, waterpower assists cutting type internal cutter, comprises top connection 1, connecting axle 2, cylindrical shell 3, turbine bearing mounting base 4, bearing 5, turbine 6, feed nut 7, nut lock rationed marketing 8, swivel feeding cover 9, pedestal stop pin 10, feeding connecting rod 11, swivelling tool-holder 12, cutter 13, tool feeding pedestal 14, connecting pin 15, thrust bearing 16, swivelling tool-holder bearing support 17, bottom link 18, link stop pin 19, lower contact 20.Described top connection 1 is arranged on upper tool part, for jointed rod, described connecting axle 2 is for connecting top connection 1 and lower contact 20, and for supporting each part in cylindrical shell 3, it is inner that described turbine bearing mounting base 4 is arranged on cylindrical shell 3, for installing bearing 5, described turbine 6 is arranged between bearing 5, and overlap 9 with swivel feeding and be connected by the feather key on it, described feed nut 7 is cemented on cylindrical shell 3 by nut lock rationed marketing 8, and overlap 9 Screw assemblies with swivel feeding, described tool feeding pedestal 14 is connected on swivel feeding cover 9 by pedestal stop pin 10, described feeding connecting rod 11 is connected with tool feeding pedestal 14 and cutter 13 by connecting pin 15, described swivelling tool-holder 12 coaxially assembles with connecting axle 2, and cutter 13 are installed thereon, described thrust bearing 16 keeps in touch with swivelling tool-holder 12, and be arranged on swivelling tool-holder bearing support 17, described bottom link 18 is arranged on lower contact 20 by link stop pin 19, and connect top connection 1 by connecting axle 2.
Instrument is transferred to the position of predetermined cuts tubing string, logical circulation fluid drives turbine 6 to rotate, rotated by feather key driven rotary feeding cover 9, relatively to rotate because feed nut 7 and swivel feeding overlap 9, thus generation axial displacement, swivel feeding overlaps 9 carry its tools feeding pedestals 14 rotations and produces simultaneously and moves axially, moving axially of tool feeding pedestal 14 drives feeding connecting rod 11 to open, thus drive cutter 13 to move radially along the chute generation of swivelling tool-holder 12, meanwhile, swivel feeding cover 9 with tool feeding pedestal 14 be rotated through feeding connecting rod 11 driven rotary knife rest 12 and cutter 13 rotate, cutter 13 produce rotation and radial feed motion simultaneously, thus start to cut tubing string, until tubing string is cut off, when stopping the circulating of circulation fluid, cutter 13 still can not be regained, namely by this instrument, tubing string more than cut place is taken out this moment, in addition, while the power cutting tubing string provided utilizing circulation fluid, if rotate tubing string can accelerate cutting speed, raise the efficiency.
