Description
Technical field
The utility model relates to a kind of slip system, particularly the cylindrical slip system of one.
Background technology
When carrying out drilling operation, being threaded owing to using between drilling tool, needing to use slip system clamping drilling tool to carry out connecting and shackle.Mainly there is following problem in existing slip system: (1) slips is generally be fixed on slip spider by pressing plate, makes fixing and unstable, easily produces displacement and loosening, define the grip strength of slip spider when grip strength is excessive; (2) surface of existing slips is commonly a plane, easily causes surface of drill stem to damage during clamping drilling tool; (3) fixed work order of slip spider and oil cylinder is comparatively loaded down with trivial details, makes installation and removal more inconvenient.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cylindrical slip system.The utility model not only has that grip strength is large, installation and removal more for convenience, and effectively can protect drilling tool, solves the excessive problem causing surface of drill stem to be damaged of grip strength.
The technical solution of the utility model: a kind of cylindrical slip system, comprises slip spider, and the inboard of slip spider is provided with clamping face, on clamping face, symmetry offers cylinder groove, be provided with cylindrical slips in cylinder groove, the surface of slips is embedded with slips sheet, and the rear side of slips is provided with screw hole; The outside of described slip spider is provided with stud bolt hole, and stud bolt hole and screw hole agree with, and is provided with the screw of stationary slip seat and slips; Slip spider is also provided with through axis hole.
In above-mentioned cylindrical slip system, described slip spider is also provided with the twice blind hole vertical with axis hole, and twice blind hole is set in parallel in axis hole both sides, in blind hole, is embedded with U-shaped snap ring; Described slip spider is other is also connected with oil cylinder, and the output shaft of oil cylinder stretches in axis hole, and the two-arm of U-shaped snap ring is agreed with mutually with the annular groove on output shaft.
In aforesaid cylindrical slip system, described slips sheet is alloy slips sheet.
In aforesaid cylindrical slip system, described clamping face is arc clamping face.
In aforesaid cylindrical slip system, the surface of described slips is a cambered surface.
In aforesaid cylindrical slip system, the radian of described slips is consistent with the radian of clamping face.
In aforesaid cylindrical slip system, the surface of described slips sheet is provided with taper clamping projection.
Compared with prior art, the utility model offers cylinder groove on the clamping face of slip spider, cylindrical slips is set in cylinder groove, slips agrees with in cylinder groove, improve the stability maintenance of slip spider and slips, avoid and easily produce displacement and loosening problem when grip strength is excessive, thus improve the grip strength of slip spider.As preferably, the both sides of slip spider upper shaft hole are provided with parallel blind hole, and the output shaft of oil cylinder stretches in axis hole, and the two-arm of U-shaped snap ring is agreed with mutually with the annular groove on output, slip spider and oil cylinder are fixed, and this design makes the Assembly And Disassembly of slip spider and oil cylinder very convenient.Further, described clamping face is arcwall face, therefore when clamping drilling tool, can available protecting surface of drill stem, and avoid the excessive problem causing surface of drill stem to be damaged of grip strength.The surface of slips sheet described is further provided with taper clamping projection, can improve grip strength further.
