Abstract
The utility model is a kind of Rapid connecting bolt, the connection being particularly useful for petroleum industry oil, well wellhead assembly and robbing between spraying equipment and well up flange.This connecting bolt comprises bolt body and nut, and nut is connected with bolt body by screw thread, has lock dog installation cavity and eject window in the bottom of bolt body, and this lock dog installation cavity is communicated with ejection window, and spring is loaded between two lock dogs; Two lock dogs are installed in lock dog installation cavity by bearing pin, can eject from ejection window.This bolt effectively can reduce the connect hours of connected component, completes connection fast, time saving and energy saving.When being more suitable for petroleum industry oil/water well generation gas blowout accident, installing wellhead device, to use when robbing spraying equipment.Can significantly shorten the blowout control time, avoid the heavy economic losses that blowout out of control causes.
Description
Technical field
The utility model relates to the connecting bolt, particularly a kind of Rapid connecting bolt that connected element uses, the connection being particularly useful for petroleum industry oil, well wellhead assembly and robbing between spraying equipment and well up flange.
Background technique
Producing at oil/water well and blowout occurs in underground work process is generally because strata pressure change is large, wellhead equipment damages and caused.Liquid in well is constantly gushed out well head, not only causes environmental pollution, and the large well of strata pressure also can damage the person due to the impact of air-flow and liquid.Control blowout needs to rob dress and robs spraying equipment, if wellhead assembly damages, also needs the wellhead assembly more renewed to control blowout.The connection of wellhead assembly and well up flange is completed by bolt, used well head bolt two is provided with screw thread, the nut on first first-class one side is needed during installation, by bolt through after the bolt hole of equipment again by another one nut on bolt, could the connection of completed well jaws equipment and fastening after the nut tightening on both sides.Common bolt, owing to one being that needs two nuts realize fastening, adding and robs the spray time.Two is due to a large amount of well head of gushing out of the liquid in well during blowout, causes well head sight line unclear and can not be with upper cap nut normally, and also spray speed is robbed in impact.Three is that screw thread on bolt easily retains greasy filth, causes removing nut time-consuming, effort.
Summary of the invention
The purpose of this utility model is to provide a kind of Rapid connecting bolt, time saving and energy saving, reduces the connect hours of connected component, completes connection fast, shortens the blowout control time.
The utility model is achieved in that a kind of Rapid connecting bolt comprises bolt body and nut, nut is connected with bolt body by screw thread, have lock dog installation cavity in the bottom of bolt body and eject window, this lock dog installation cavity is communicated with ejection window, and spring is loaded between two lock dogs; Two lock dogs are installed in lock dog installation cavity by bearing pin, can eject from ejection window.
The beneficial effects of the utility model are: this bolt effectively can reduce the connect hours of connected component, completes connection fast, time saving and energy saving.When being more suitable for petroleum industry oil/water well generation gas blowout accident, installing wellhead device, to use when robbing spraying equipment.Only need to exert oneself a little when this bolt is installed, its lock dog shrink undergauge just by the bolt hole between wellhead assembly and upper flange, by after under the action of the spring lock dog rebound return.Because the nut on bolt body top can load in advance, be screwed onto suitable position in advance, after the utility model inserts the bolt hole of wellhead assembly and upper flange, only need again by 1 to 2 button on nut, the fastening of blowout control device or wellhead assembly can be realized, can significantly shorten the blowout control time, avoid the heavy economic losses that blowout out of control causes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model lock dog.
Embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, see Fig. 1 and Fig. 2, a kind of Rapid connecting bolt comprises bolt body 1 and nut 2, nut 2 is connected with bolt body 1 by screw thread, have lock dog installation cavity in the bottom of bolt body 1 and eject window, this lock dog installation cavity is communicated with ejection window, and spring 5 is loaded between two lock dogs 3; Two lock dogs 3 are installed in lock dog installation cavity by bearing pin 4, can eject from ejection window.The body lower part of lock dog 3 is provided with handler, and the bottom of this handler is provided with pinned connection hole, and the handler correspondence of two lock dogs 3 is arranged on the outside of body; The upper inner of two lock dog 3 bodies be equipped with spring mounting hole, upper body outside correspondence lower inclined plane is set.Two lock dogs 3 are connected with bearing pin 4 by handler, and the mounting hole of bearing pin 4 is located on the wall of lock dog installation cavity, and the two ends of spring 5 are separately fixed in the spring mounting hole of two lock dogs 3.Distance between nut 2 to lock dog 3 is greater than the total thickness of two connected components.The lower end of bolt body 1 is also provided with spanner side, and nut 2 is provided with lancing door 6, and the greasy dirt in bolt body 1 screw thread can be made to extrude from this hole.During use, by the distance adjustment between nut 2 and lock dog 3 to being a bit larger tham the total thickness of robbing spraying equipment well head and well up flange.Bolt body 1 is inserted the bolt hole of wellhead assembly and upper flange, lock dog 3 undergauge, by after under the active force of spring 5, two lock dogs 3 are opened; Locking nut 2 is tightened 1 to 2 button, can realize tightening blowout control device.The spanner side of bolt body 1 lower end, can upon pull-up upper and lower simultaneously use spanner fastening.
