In order to realize the purpose, the utility model provides a technical scheme is:
the utility model provides an crowded stifled wellhead assembly, including crowded stifled wellhead assembly body, all can dismantle on the branch pipe of crowded stifled wellhead assembly body and be fixed with the fixation clamp, the fixation clamp lower extreme all is fixed with vertical sleeve pipe, it has rather than endocentric polished rod to slide in the sleeve pipe to peg graft, sleeve pipe lower extreme threaded connection has the locking screw who is used for locking the polished rod, the polished rod lower extreme rotates and is connected with the rotary rod parallel with the branch pipe, the rotary rod is served towards one of wellhead assembly body and all is fixed with the rubber kicking block, the terminal surface of crowded stifled wellhead assembly body of rubber kicking block orientation is the cambered surface, the laminating of cambered surface and crowded stifled wellhead assembly body lower extreme outer fringe, the length of rotary rod is less than the length of branch pipe.
Specifically, the fixation clamp includes the U type fork, and the branch pipe is located the U type fork of its one side, and equal threaded connection has adjusting screw on two vertical portions of U type fork, all rotates on the adjusting screw to be connected with the arc, and the arc is located the U type fork, and two arcs in the U type fork carry out the centre gripping to the branch pipe.
Specifically, the rubber top block is made of elastic rubber.
Specifically, the inner edge of the arc-shaped plate is provided with anti-skid lines.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses, simple structure, convenient to use can improve the installation effectiveness of crowded stifled wellhead assembly body, can reduce installation cost, and convenient to use can with crowded stifled wellhead assembly body coupling, convenient rather than together packing vanning, and convenient transportation can be dismantled after the installation is accomplished, circulated use.

Detailed Description
As shown in fig. 1-3, a wellhead squeezing and plugging device comprises a wellhead squeezing and plugging device body 1, wherein a fixing clamp is detachably fixed on a branch pipe 5 of the wellhead squeezing and plugging device body 1, the fixing clamp comprises a U-shaped fork 2, the branch pipe 5 is positioned in the U-shaped fork 2 on one side of the U-shaped fork, two vertical parts of the U-shaped fork 2 are respectively in threaded connection with an adjusting screw 4, an arc-shaped plate 3 is respectively and rotatably connected onto the adjusting screw 4, anti-skid lines are processed on the inner edge of the arc-shaped plate 3, the arc-shaped plate 3 is positioned in the U-shaped fork 2, the two arc-shaped plates 3 in the U-shaped fork 2 clamp the branch pipe 5, a vertical sleeve 6 is fixed at the lower end of the fixing clamp, a polish rod 8 concentric with the sleeve 6 is inserted and slidably in the sleeve 6, a locking screw 7 for locking the polish rod 8 is in threaded connection at the lower end of the sleeve 6, a rotary rod 9 parallel to the branch pipe 5 is rotatably connected at the lower end of the polish rod 8, a rubber jacking block 10 is fixed at one end of the rotary rod 9 facing the wellhead squeezing and plugging device body 1, the rubber kicking block 10 is the elastic rubber material, and the terminal surface of rubber kicking block 10 orientation crowded stifled wellhead assembly body 1 is the cambered surface, the cambered surface is laminated with crowded stifled wellhead assembly body 1 lower extreme outer fringe, and the length of rotary rod 9 is less than the length of branch pipe 5.
This device is when needing the vanning packing, make branch pipe 5 be located between two arcs 3 of fixation clamp, rotate adjusting screw 4, make two arcs 3 carry out the centre gripping to branch pipe 5, fixation clamp and 5 fixed connection of branch pipe this moment, rotate rotary rod 9, make rotary rod 9 and branch pipe 5 parallel, and make the cambered surface of rubber kicking block 10 and the laminating of crowded stifled 1 lower extreme outer fringe of wellhead assembly body, rotary rod 9 can be stabilized this moment, because rotary rod 9 is parallel with branch pipe 5, the length of rotary rod 9 is less than the length of branch pipe 5, consequently, when packing the vanning to this device, rotary rod 9 can not form the hindrance. When crowded stifled wellhead assembly body 1 of installation, rotatory rotary rod 9, make rubber kicking block 10 take place elastic deformation back and crowded stifled wellhead assembly body 1 separation, and make rotary rod 9 perpendicular with branch pipe 5, not hard up locking screw 7, make polished rod 8 and rotary rod 9 down, when 9 lower extremes of rotary rod and crowded stifled 1 lower extreme parallel and level of wellhead assembly body, rotate locking screw 7, it is stable with polished rod 8, rotary rod 9 can right stability crowded stifled wellhead assembly body 1 this moment, can prevent it from empting during the installation. The fixing clamp can be separated from the branch pipe 5 after the wellhead device body 1 is squeezed and plugged.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
