Abstract
The utility model discloses a slip-type sleeve hanger which comprises a base, a sealing ring, an anti-extrusion plate and a slip structure, wherein the slip structure consists of two half parts; each half part comprises a slip seat, a slip tooth and a slip tooth fixing ring; the slip tooth is limited in the slip seat by the slip tooth fixing ring and fixedly connected with the slip seat by screws; and the base, the sealing ring and the anti-extrusion plate are fixedly connected with the slip seat in one half part by screws. The slip-type sleeve hanger is characterized in that the two half parts are rotatably connected with each other by a hinge at one side; the other side of the half part is provided with an elastic opening hook; the other half part is correspondingly provided with a polished rod pin; and under the installation state, the opening part of the elastic opening hook is clamped on the polished rod pin. In the utility model, the two half parts are connected with each other by the hinge at one side and are connected with each other by the quick elastic opening hook which replaces the existing bolt fixing way at the other side; the parts can not be missed, the operation time is short, the operation is convenient and special tools are not needed.
Description
Technical field
The utility model relates to a kind of wellhead assembly, is specifically related to a kind of slip-type casing tube that is used for Fast Installation and hangs.
Background technology
Casing hanger is a kind of important wellhead assembly, is used for supporting sleeve.Casing hanger is divided into mandrel formula and slip-type two big classes usually.Wherein, conventional slip-type casing tube is hung general dimidiation, the two halves casing hanger is embraced sleeve pipe in installation process after, connects into an integral body by bolt, thereby needs special instrument to operate in the execute-in-place process, and efficient is lower like this.In addition, because bolt does not combine with casing hanger, if the situation that bolt is fallen in the well or bolt is lost takes place in the installation process, whole erection work will be stagnated because casing hanger can not install, and causes bigger loss.
Summary of the invention
The utility model purpose provides a kind of slip-type casing tube to hang, and by the improvement of structure, does not need to use the bolt of split, to realize Fast Installation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of slip-type casing tube is hung, comprise base, sealing ring, anti-extrusion board and slips structure, described slips structure is made of two and half parts, each half part comprises slip spider, slip insert and slip insert retainer ring, slip insert is limited in the slip spider and by screw by the slip insert retainer ring fixedlys connected with slip spider, described base, sealing ring is fixedlyed connected with the slip spider in one and half parts through screw with anti-extrusion board, one side of described two and half parts is rotationally connected through the hinge formation, the opposite side of one and half parts is provided with the elastic opening hook, correspondence is provided with the polished rod pin on another half part, under installment state, the peristome of described elastic opening hook is arranged on the described polished rod pin.
During use, outwards push the elastic opening hook aside, unclamp hook, can open casing hanger this moment, and hook is returned to fastening position under spring action.After embracing the sleeve pipe of suspension, outwards push the elastic opening hook aside, directly close up casing hanger, hook is hung on the polished rod pin, this moment, casing hanger was fixed together, and finished assembling.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
One side adopts hinge to connect between the utility model two and half parts, and opposite side adopts quick elastic opening hook to replace adopting in the past the mode of bolt, and part can not lost, and the activity duration is short, and is easy to operate, do not need special instrument.
