On the basis of the above-mentioned embodiments, the present application continues to describe the technical features and functions of the technical features mentioned therein in detail to help those skilled in the art to fully understand the technical solutions of the present application and reproduce the same.

The main principle of the application lies in that: the upper joint 12 and the lower joint 9 are a pair of right-handed outer conical threads and inner conical threads of the petroleum drill pipe which are matched with each other. When the drilling tower 17 is erected and falls back, the mechanical rotary motion transmitted to the power head 16 on the drilling tower 17 through the vertical shaft 15 is connected and disconnected through the conical thread connection of the upper connector 12 and the lower connector 9. When the drilling tower is erected, the vertical shaft 15 makes positive rotary motion, and the rotary lower joint 9 can be automatically screwed on the upper joint 12 under the action of the elastic auxiliary mechanism, so that the mechanical rotary motion transmitted to the power head 16 on the drilling tower 17 through the vertical shaft 15 is quickly connected and completed.

When the vertical shaft 15 needs to do reverse rotation movement, the reverse rotation pin 8 needs to be inserted into the waist groove of the upper connector 12 through the through hole on the lower connector 9, and the tail part of the reverse rotation pin 8 needs to be fixed in the fixture block 7 through the transverse pin. Reverse rotation of the vertical shaft 15 will cause the tapered thread connection between the lower and

upper joints

9 and 12 to fail and power is transmitted through the reverse rotation pin 8.

When the upper joint 12 needs to be separated from the lower joint 9, the reversing pin 8 only needs to be taken out of the through hole of the lower joint 9, the vertical shaft 15 does reverse rotation movement, the conical threaded connection between the upper joint 12 and the lower joint 9 fails, and the rotating lower joint 9 can be separated from the upper joint 12. When falling back, the elastic auxiliary mechanism of the lower joint 9 is only slightly pressed down to not influence the separation track of the upper joint 12.

As shown in fig. 1 and 2, the application discloses a connecting and separating mechanism for forward and reverse rotation power transmission of a vertical shaft and a power head of a drilling machine, wherein a mandril base 2 is fixed at the lower end of a vertical shaft sleeve 18 through a bolt. The hexagonal nut 1 is welded to the outer side of the center hole of the ejector rod seat 2, the ejector rod sleeve 4 can freely slide in the inner cavity of the vertical shaft 14, and the spring 5 arranged between the universal coupling 6 and the ejector rod sleeve 4 can be compressed. The ejector rod 3 can support the ejector rod sleeve 4 after being screwed in through the hexagon nut 1. When the vertical shaft type locking device is used, the length of the ejector rod 3 needs to be adjusted in advance, the ejector rod 3 is locked through the hexagon nut 1, and the ejector rod 3 does not need to be adjusted afterwards, so that the vertical shaft 15 extends out of the vertical shaft sleeve 18 under the action of the spring 5, and the vertical shaft 15 can retract in the vertical shaft sleeve 18 under the action of external force.

In this application the top welding of vertical scroll 5 have universal joint 6's one end, universal joint 6's the other end has lower clutch 9 through bolted connection. A through hole into which the reverse rotation pin 8 is inserted is formed in the lower joint 9, and a latch 7 corresponding to the through hole into which the reverse rotation pin 8 is inserted is fixed by welding. The number of the through holes for inserting the fixture blocks 7 and the reverse rotation pins 8 can be 4. The reversing pin 8 described in the above paragraph can be inserted into the waist groove of the upper joint 12 through the through hole reserved on the lower joint 9, and the transverse pin at the tail of the reversing pin 8 is firmly clamped and fixed in the fixture block 7, so that the reversing pin 8 is effectively prevented from flying out when the drilling machine rotates at high speed. An inner conical thread is processed inside the upper part of the lower joint 9, and the upper joint 12 is screwed with the inner conical thread of the lower joint 9 through the matching of the outer conical thread and the inner conical thread. That is, by abutting the external tapered thread on the upper sub 12 against the internal tapered thread on the lower sub 9 when the rig 17 is erected, and by making a positive swivel movement of the rig, the swivel lower sub 9 can be screwed onto the internal tapered thread of the upper sub by its own internal tapered thread.

The above paragraphs describe the engagement of the upper sub 12 with the lower sub 9 when the rig 17 is erected, and in particular, when the rig 17 is erected, only a portion of the force is applied to the lower sub 9 to retract the vertical shaft 15 connected thereto into the vertical sleeve 14, preferably by a distance that does not affect the path of movement of the upper sub 12 when the rig 17 is erected. When the drilling tower 17 is completely erected, the acting force applied to the lower joint 9 is removed, the vertical shaft 15 extends out of the vertical shaft sleeve 18 under the action of the spring 5, so that the lower joint 9 is driven to be close to and tightly attached to the upper joint 12, and the inner conical threads on the lower joint 9 and the outer conical threads of the upper joint 12 are screwed under the forward rotary motion of the drilling machine, so that the forward rotary force is transmitted.

In this application, the top sub 12 is threaded with the right-hand internal taper threads on the end of the hexagonal rod 14 in the rig 17. And a reverse hexagonal sleeve 13 is also sleeved on the hexagonal rod 14. The inner hole of the reverse hexagonal sleeve 13 is attached to the outer surface of the hexagonal rod 14 and fixed to the upper joint 12 through bolt connection. The hexagonal rod 14 is a hollow rod, and one end of the reinforcing shaft 11 is welded in an inner hole of the end part connected with the upper joint 12. Two threaded holes are reserved at the other end of the reinforcing shaft 11, and the threaded holes can be aligned with the bottom of a square groove reserved in the upper joint 12 after the internal threads in the upper joint 12 and the external threads on the hexagonal rod 14 are screwed. Locking plate 10 is gone into to the square groove card that 12 tip of top connection were reserved, and the shape and the square groove of locking plate 10 correspond, and locking plate 10 accessible bolt is connected with the screw hole fastening that reserves on the reinforcing shaft 11.

In the above paragraphs, when the drilling machine makes a positive slewing motion, the power can be transmitted through the lower joint 9 → the upper joint 12 → the hexagonal rod 14. When the drilling machine does reverse rotation movement, due to the fact that the threaded connection between the drilling machine and the drilling machine fails, power transmission of the drilling machine is jointly transmitted through the following two paths: one is through the lower joint 9 → the reverse pin 8 → the upper joint 12 → the reverse hexagonal bushing 13 → the hexagonal rod 14, and the other is through the lower joint 9 → the reverse pin 8 → the upper joint 12 → the lock plate 10 → the reinforcing shaft 11 → the hexagonal rod 14.

Namely, when the forward rotation movement is stopped and the drilling machine does reverse rotation movement, the reverse rotation pin 8 needs to be inserted into the waist groove of the upper joint 12 through the through hole reserved in the lower joint 9, and the reverse rotation pin 8 is fixed in the fixture block 7 through the transverse pin at the tail part of the reverse rotation pin 8, so that the reverse rotation pin 8 is prevented from being thrown out when the drilling machine rotates at high speed. After the reverse rotation pin 8 is pulled out from the through hole reserved in the lower joint 9, when the drilling machine does reverse rotation movement again, the right-handed taper thread connection between the upper joint 12 and the lower joint 9 fails, and the rotating lower joint 9 can be separated from the upper joint 12, so that the separation between the upper joint 12 and the rotating lower joint is realized.

Finally, although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description of the present description is for clarity reasons only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
