Abstract
The utility model belongs to a clamping device of a drilling tool or a sleeve, which can replace a core in a well drilling project. In particular, the utility model relates to a fast-replaced slip device. The fast-replaced slip device comprises slip body sheets and slip inserts. The combined slip body sheets are arranged in a conical through hole of a slip base. The outer conical surfaces of the slip body sheets are matched with the conical surface of the through hole of the slip base. Single-piece slip insert sheets, on which sawtoothed inserts are evenly distributed, are respectively arranged on the corresponding slip body sheets by positioning devices which are respectively arranged on cylindrical surfaces inside the slip body sheets. The slip insert sheets are locked by locking devices arranged at the top surfaces of the slip body sheets. The fast-replaced slip device has reasonable structure and strong universality, can clamp the pipe poles of drilling tools with different diameters, realizes convenient operation and high work efficiency, reduces the labor intensity and the occupied space and is convenient for site work.
Description
Technical field
The utility model belongs to can change the drilling tool of fuse or the clamping device of sleeve pipe, particularly quick change slip system in drilling engineering.
Background technology
Put in the brill process at oil drilling, drilling tool tubing string shackle when operation on well head carries out, by slips carry out temporary fixed, hold.Traditional fix, hold instrument-slips, be placed in the rotating disk endoporus, the rotating disk endoporus is up big and down small infundibulate.When the drilling tool tubing string was held by slips, the weight of drilling tool tubing string acted on the slips, because the tapering effect of rotating disk endoporus, slips can block tighter and tighter.The drilling tool tubing string can be gone up button after obtaining holding and fixing, perhaps shackle operation.After last shackle operation is finished, carry the drilling tool tubing string gently, remove the load on the slips, propose slips, vacate the well head space, just can more than carry or transfer the drilling tool tubing string, by well head, the drilling tool tubing string arrive to be gone up the shackle position, below last shackle position, block the drilling tool tubing string again, go up button with tong, perhaps shackle operation, so repeatedly.
The on-the-spot slips that uses have three with multi-disc; Have manual, pneumatic and surge.Main action principle is that each slips sheet is linked, be convenient to put into, take out and synchronously about, surround and block drilling tool.The inner edge surface of each slips sheet is outward a circular arc, is made up of slips lamellar body and slip insert.The slips lamellar body contacts with the rotating disk endoporus, and slip insert contacts with the drilling tool tubing string.Slip insert general from the side or top dovetail groove insert, be mounted in the slips lamellar body, fix with pin or screw.Three slips lamellar bodies of three slips respectively by 10-20 sheet slip insert from top insertion; Each slips body sheet of multi-disc slips has a slice slip insert to insert from the side respectively.Three slips, multi-disc slips, manual slip, air operated slips, the slips that surges all have characteristics: the diameter of the drilling tool tubing string that holds is that fix, unique.That is to say: a kind of slips can only hold a kind of drilling tool tubing string of diameter, can not hold the drilling tool tubing string of other diameters, multiple drilling tool tubing string, and the slips of the multiple model of needs, interchangeability is poor between the slips.Slip insert can't be changed in the scene, often will be equipped with multiple slips on the limited rig floor in space, and site work is very inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of quick change slip system, and it is rational in infrastructure, and highly versatile can hold the drilling tool tubing string of different-diameter, and is easy to operate, and high efficiency reduces labour intensity, occupies little space, and is convenient to field operation.
The purpose of this utility model is achieved in that a kind of quick change slip system, comprise slips body sheet and slip insert, combination slips body sheet is installed in the circular cone through hole of slips pedestal, the outer conical surface of slips body sheet matches with the taper seat of slips pedestal through hole, the monolithic slip insert sheet that is evenly equipped with notched teeth is installed in respectively on the corresponding slips body sheet by the positioner that is provided with on each slips body sheet inner cylinder face, and by the locking device on the slips body sheet end face slip insert sheet is locked.
Slips pedestal of the present utility model is placed on the rotating disk, each slips body sheet of the present utility model is only adorned a slice slip insert sheet, during installation, open the locking device on the slips body sheet end face, above slips body sheet, insert, be installed on the slips body sheet by positioner, and the slip insert sheet locked by the locking device on the slips body sheet end face.Therefore, it is very convenient that the utility model is changed the slip insert sheet, when needing to change slips, open the locking device on the slips body sheet end face, extract the slip insert sheet out from the upper surface of each slips body sheet, just can be replaced with the slip insert sheet of required specification, to hold the drilling tool tubing string of respective diameters.The utility model is rational in infrastructure, and highly versatile can hold the drilling tool tubing string of different-diameter, and is easy to operate, and high efficiency reduces labour intensity, occupies little space, and is convenient to field operation.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the sectional structure schematic diagram of the utility model embodiment 1;
Fig. 2 is the sectional structure schematic diagram of the utility model embodiment 2.
The specific embodiment
A kind of quick change slip system, embodiment 1 as shown in Figure 1, comprise slips body sheet and slip insert, slips pedestal 2 is placed on the rotating disk 1, combination slips body sheet 3 is installed in the circular cone through hole of slips pedestal 2, the outer conical surface of slips body sheet 3 matches with the taper seat of slips pedestal 2 through holes, the monolithic slip insert sheet 4 that is evenly equipped with notched teeth is installed in respectively on the corresponding slips body sheet 3 by the positioner that is provided with on each slips body sheet 3 inner cylinder face, and by the locking device on slips body sheet 3 end faces slip insert sheet 4 is locked.Positioner is for axially to be provided with dovetail groove on slips body sheet 3 inner cylinder faces, the matrix of slip insert sheet 4 matches with dovetail groove.Positioner is for axially being provided with the dovetail raised line on slips body sheet 3 inner cylinder faces, the dovetail groove that the slip insert sheet 4 matrix back sides are provided with matches with the dovetail raised line.Locking device is installed with fixation clip 8 movingly on the top of slips body sheet 3 plate groove 6 to be set radially in plate groove 6, at pin 7 or bolt that slips body sheet 3 end faces are provided with that fixation clip 8 is fixing, fixation clip 8 is with 4 lockings of slip insert sheet.Affixedly on the end face of slips body sheet 3 carry plate 5 or carry handle.Combination slips body sheet 3 is made up of the 3-6 sheet.Each slips body sheet 3 can be carried plate 5 with each slips body sheet 3 link by chain link, be convenient to put into, take out and synchronously about, surround and block drilling tool.Slips body sheet 3 also can link into an integrated entity side by side, mentions with carrying handle.Embodiment 2 as shown in Figure 2 is the structural representation when upwards extracting a slice slips body sheet 3.The cone-shaped hole of slips pedestal 2 is the cone-shaped hole with step, and combination slips body sheet 3 is installed in slips pedestal 2 has the cone-shaped hole of step, and the outer conical surface that slips body sheet 3 has step matches with the step taper seat of slips pedestal 2 through holes.When upwards extracting slips body sheet 3, as long as rise along the step taper seat of slips pedestal 2 through holes, just vacating space easily passes through the drilling tool tubing string of centre.
