Tooth thread links, and stable connection is inadequate, and the stability for connecting and detaching is inadequate, it occur frequently that failure in the course of work.
Invention content
Technical problem to be solved by the invention is to provide a kind of oil drilling safety joint, pin end and female connector pass through
It is remotely controlled the flexible inserted link connection of push-rod electric machine, stable connection is good, and rotation synchronism is strong, and the reliability for connecting and detaching
By force.
To achieve the above object, the present invention provides technical solution below：
The oil drilling safety joint includes the pin end and female connector of mutual transition cooperation, and pin end is far from female connector one
End is provided with the threaded hole of truncated cone-shaped, and female connector is equipped with the screw boss of truncated cone-shaped, the size of screw boss far from pin end one end
Identical as threaded hole, screw boss and the mutual screw-thread fit of threaded hole, pin end side are symmetrically provided with two pin end jacks, and mother connects
Head is provided with the identical female connector jack of two diameters corresponding to two pin end jacks, and remote control push-rod electric machine is equipped with inside pin end,
Two flexible inserted links of remote control push-rod electric machine are inserted into respectively in both sides corresponding pin end jack and female connector jack.
Preferably, the pin end, female connector, screw boss are made of stainless steel, and female connector and screw boss are whole
Body structure.
Preferably, accumulator is installed inside the remote control push-rod electric machine, and is remotely controlled push-rod electric machine equipped with remote controler.
Preferably, the length of the flexible inserted link is equal to the sum of pin end jack and female connector jack length, and stretch inserted link
Coordinate with pin end jack and the mutual transition of female connector jack.
It is using the advantageous effect of above technical scheme：The oil drilling safety joint when in use can be by being remotely controlled push rod
The inserted link that stretches of motor operation two is inserted into the corresponding pin end jack in both sides and female connector jack and connects pin end and mother respectively
Head is stably connected with, and pin end and female connector become stable rigidity entirety, and the screw boss of pin end is connect with drill bit thread, female
The threaded hole of connector is connect with drill rod thread, can protect top rod.When bit freezing, underground drilling accident occurs, can remotely grasp
Vertical remote control push-rod electric machine allows two flexible inserted links to exit pin end jack and female connector jack, can allow pin end and female connector immediately
It separates, convenient for drilling rod is dismantled and proposed from safety joint place, can safely pick up drilling rod, be left inside guarantee oil drilling
Machine tool is less as possible.
Description of the drawings
The specific implementation mode of the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structure sectional view of oil drilling safety joint of the present invention.
Wherein, 1- pin ends, 2- female connectors, 3- remote controls push-rod electric machine, 4- screw boss, 5- threaded holes, 6- pin ends are inserted
Hole, 7- female connectors jack, the flexible inserted links of 8-.
Specific implementation mode
The preferred embodiment for oil drilling safety joint that the invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 shows the specific implementation mode of oil drilling safety joint of the present invention：
As shown in Figure 1, the oil drilling safety joint includes the pin end 1 and female connector 2 of mutual transition cooperation, pin end
1 is provided with the threaded hole 5 of truncated cone-shaped far from 2 one end of female connector, and the screw thread that female connector 2 is equipped with truncated cone-shaped far from 1 one end of pin end is convex
The size of platform 4, screw boss 4 is identical as threaded hole 5, screw boss 4 and 5 mutual screw-thread fit of threaded hole, 1 side pair of pin end
Title is provided with two pin end jacks 6, and female connector 2 is provided with the identical female connector jack 7 of two diameters corresponding to two pin end jacks 6, public
Remote control push-rod electric machine 3 is installed, two flexible inserted links 8 of remote control push-rod electric machine 3 are inserted into the corresponding public affairs in both sides respectively inside connector 1
In connector receptacle 6 and female connector jack 7.
Pin end 1, female connector 2, screw boss 4 are made of stainless steel, sturdy and durable, and corrosion resistance and good, mother connect
First 2 and screw boss 4 be overall structure.Accumulator is installed, accumulator is remote control push-rod electric machine 3 inside remote control push-rod electric machine 3
Electric energy is provided, and is remotely controlled push-rod electric machine 3 equipped with remote controler, remote controler can manipulate two flexible inserted links 8 of remote control push-rod electric machine 3
It stretches out or retraction is remotely controlled inside push-rod electric machine 3.The length of flexible inserted link 8 is equal to 7 length of pin end jack 6 and female connector jack
The sum of, the inserted link 8 that stretches coordinates with pin end jack 6 and the 7 mutual transition of female connector jack, ensures the company of pin end 1 and female connector 2
The synchronism for connecing stability and rotation is high.Flexible inserted link 8 is made of stainless steel.
The oil drilling safety joint can be respectively inserted into when in use by being remotely controlled the two flexible inserted links 8 of operation of push-rod electric machine 3
Pin end 1 and female connector 2 are stably connected in the corresponding pin end jack 6 in both sides and female connector jack 7, pin end 1 and mother
