Formula, but flange docking has that docking speed is slow, dismounting inconvenience.
Invention content
When it is an object of the invention to overcome telescopic drill rod to use flange continued access, inconvenient problem is dismounted, one kind is provided
The flexible chain structure of telescopic drill rod continued access can be fast implemented.
In order to achieve the above object, the invention is realized in this way:
A kind of flexible chain structure for telescopic drill rod continued access comprising two sections of drilling rod bodies for waiting for continued access, further include chain body,
The chain body includes steel cable, steel ball, rope clamp and pull rod, and steel ball has multiple and is threaded through on steel cable successively, the both ends difference of steel cable
Rope clamp and pull rod are set and is stopped and can not be dropped out by rope clamp and pull rod to wear steel ball on a steel cord;On the top of drilling rod body
Corresponding semi-circular shape groove is opened up on end and tail end outer wall, when two section drilling rod bodies plug end to end, semicircular ring at two
Connected in star mutually merges to form complete circular ring shape through-hole, the circular ring shape through-hole on the outside drilling rod body outer wall be equipped with notch,
Chain body is inserted into the circular ring shape through-hole to limit two section drilling rod bodies by the notch, prevents two section drilling rod bodies pines
It is de-.
The flexible chain structure for telescopic drill rod continued access, it is close that twice are at least arranged in two splicing positions for saving drilling rod bodies
Seal ring, wherein sealing ring is specifically provided in the end outer surface of drilling rod body.
The flexible chain structure for telescopic drill rod continued access further includes the gasket of cylinder, the gasket setting
Between each steel ball.
The application method of the flexible chain structure for telescopic drill rod continued access, including
Step 1 plugs the head end of a section drilling rod body and the tail end of another section drilling rod body;
Step 2, the notch that drilling rod body surface face is saved by wherein one save the semi-circular shape groove phase group pair at drilling rod body docking by two
And form complete circular ring shape through-hole;
Chain body is inserted into using the rope clamp of chain body as head end from the notch in drilling rod body surface face and fills up entire annulus by step 3
Shape through-hole, in the process, it should be ensured that the length of chain body is more than the perimeter of circular ring shape through-hole.
This structure uses above-mentioned design, by being used as the chain body of limit with steel cable flexible and steel ball, in drilling rod body
Docking at spacing ring is set, the limit purposes after two section drilling rod grafting are realized in the cooperation for passing through chain body and spacing ring.It compares
For flange docking needs the method that multiple bolts fasten successively, obviously had faster, more using the flexible chain of drawing and pulling type
Efficient feature.
Description of the drawings
Fig. 1 is the connected structure sectional view between two section drilling rod bodies.
Fig. 2 is the sectional view along A-A in Fig. 1.
Fig. 3 is the structural schematic diagram of chain body.
Specific implementation mode
It is further illustrated the present invention below by way of specific embodiment.
As shown in Figure 1, Figure 2 and Figure 3, a kind of flexible chain structure for telescopic drill rod continued access comprising two sections continued
The drilling rod body connect further includes chain body, which includes steel cable 1, steel ball 3, rope clamp 2 and pull rod, and steel ball 3 has multiple and successively
It is threaded through on steel cable 1, the steel ball 3 that rope clamp 2 and pull rod is respectively set to be threaded through on steel wire rope 1 in the both ends of steel cable 1 is by rope clamp 2
Stop with pull rod and can not drop out;Corresponding semi-circular shape groove is opened up on the top of drilling rod body and tail end outer wall, when
When two section drilling rod bodies plug end to end, semi-circular shape groove mutually merges to form complete circular ring shape through-hole, the circular ring shape at two
Through-hole on the outside drilling rod body outer wall be equipped with notch, by chain body by the notch be inserted into the circular ring shape through-hole to
By two section drilling rod body limits, prevent two section drilling rod bodies from loosening.
The flexible chain structure for telescopic drill rod continued access, it is close that twice are at least arranged in two splicing positions for saving drilling rod bodies
Seal ring, wherein sealing ring is specifically provided in the end outer surface of drilling rod body.
