Abstract
The utility model discloses a kind of flex-stem, including the body of rod, ring flange, cushion seal pad and rubber ring, the body of rod end is connect with ring flange, the card slot of annular is opened up in the flange side surface, the cushion seal pad is in the card slot；Rubber ring is cased in the connecting hole of the ring flange.The utility model is cased with rubber ring in the connecting hole of ring flange, therefore fastening bolt can do a certain amount of slight lateral displacement in connecting hole, and cushion seal pad is also added between two ring flanges, so that can produce a certain amount of length travel when two drilling rod pressure-bearings interconnected, so entire drilling rod will not be transferred vibrations to when some position of drilling rod or drill bit are generated vibration by the torque or resistance transfer of crossbar transistion, either oscillation crosswise or extensional vibration by rubber ring and buffering gasket buffering and can all be cut out in the ring flange junction of drilling rod.
Description
Technical field
The utility model relates to drilling tool technical field, in particular to a kind of flex-stem.
Background technique
Drilling machine is influenced during drilling by geological stratification variation, and stress is changing always, such as meets when unexpected
Drill bit will receive the pressure very big along drilling rod direction when to harder rock, and when encountering the biggish rock stratum of frictional force, drilling rod is just
Bigger torque is needed to export, torque becomes much larger, and drilling rod will generate vibration when pressure and torque constantly change, if adopting
With the connection type of rigidity, such as it is threadedly coupled jointed rod, the stress variation of certain point will be transmitted to entire brill on drilling rod
On bar, normal drilling operation is not only influenced, but also very big damage can be caused to drilling rod.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of flex-stems of effective slowing down vibration.
The technical solution of the utility model are as follows:
A kind of flex-stem, including the body of rod, ring flange, cushion seal pad and rubber ring, the body of rod end and ring flange
It connects, the card slot of annular is opened up in the flange side surface, the cushion seal pad is in the card slot；The ring flange
Connecting hole in be cased with rubber ring.
Further, the body of rod is hollow stem, interior to be equipped with aqueous vapor road.
Further, connecting hole is respectively positioned in card slot.
Further, ring flange is identical as the diameter of the body of rod.
Further, rubber ring is nitrile rubber circle.
The utility model has the beneficial effect that
The utility model is cased with rubber ring in the connecting hole of ring flange, therefore fastening bolt can do one in connecting hole
Quantitative slight lateral displacement, and cushion seal pad has also been added between two ring flanges, so that two brills interconnected
It can produce a certain amount of length travel when bar pressure-bearing, in order to avoid long-term vibration causes cushion seal pad to generate displacement, also
Card slot is provided in flange side surface.Therefore connection is not rigid between two connected drilling rods, allow between them
Small displacement exists, so when some position of drilling rod or drill bit are generated vibration by the torque or resistance transfer of crossbar transistion
Entire drilling rod will not be transferred vibrations to when dynamic, either oscillation crosswise or extensional vibration can all be connected in the ring flange of drilling rod
Place is by rubber ring and buffering gasket buffering and cuts out.

Fig. 2 is the utility model use state diagram；
Fig. 3 is the overlooking structure diagram of Fig. 1；
Fig. 4 is the cushion seal mat structure schematic diagram in Fig. 2.
In figure: the 1- body of rod, 11- aqueous vapor road, 2- ring flange, 21- connecting hole, 3- rubber ring, 4- card slot, 5- cushion seal
Pad, 51- through-hole, 6- fastening bolt.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
It is as shown in Figs 1-4:
A kind of flex-stem, including the body of rod 1, ring flange 2, cushion seal pad 5 and rubber ring 3,1 end of the body of rod and method
Blue disk 2 connects, it is characterised in that: the card slot 4 of annular is opened up on 2 end face of ring flange, the cushion seal pad 5 is flush-mounted in institute
It states in card slot 4；Rubber ring 3 is cased in the connecting hole 21 of the ring flange 2.
Specifically, conveying drilling fluid or coolant liquid, the body of rod 1 are hollow stem for convenience, it is interior equipped with aqueous vapor road 11.
Specifically, connecting hole 21 is respectively positioned in card slot 4 in order to play good sealing effect and damping effect, buffering
Hole 51 is got through in the position that hole 21 is correspondingly connected on gasket 5, and fastening bolt 6 is passed through the through-hole on cushion seal pad 5 by when installation
51, ensure that sealing area and cushion area are big as far as possible between two connected ring flanges 2 in this way.
Specifically, in order to reduce the resistance in going down process, ring flange 2 is identical as the diameter of the body of rod 1, naturally it is also possible to slightly
Less than the diameter of the body of rod 1.
Specifically, rubber ring 3 is nitrile rubber circle, because its oil resistivity is fabulous, wearability is higher, and heat resistance is preferable, glues
Relay is strong, more compatibly descends working environment.
The utility model is by flanged joint, and when use is staggered relatively by the ring flange 2 of two drilling rods, then theirs
It is placed in cushion seal pad 5 in card slot, then passes through connecting hole 21 with fastening bolt 6.In 21 inner sleeve of connecting hole of ring flange 2
Have a rubber ring 3, therefore fastening bolt 6 can do a certain amount of slight lateral displacement in connecting hole, and two ring flanges 2 it
Between also added cushion seal pad 5 so that can produce a certain amount of length travel when two drilling rod pressure-bearings interconnected, be
It avoids long-term vibration that cushion seal pad 5 is caused to generate displacement, card slot 4 is provided with also on 2 end face of ring flange.Therefore two
It is not rigid connection between connected drilling rod, small displacement is allowed to exist between them, so working as some position of drilling rod
Entire drilling rod will not be transferred vibrations to when either drill bit is generated vibration by the torque or resistance transfer of crossbar transistion no matter
It is that oscillation crosswise or extensional vibration all can be buffered and be disappeared by rubber ring 3 and buffering gasket 5 in 2 junction of ring flange of drilling rod
It cuts.
The embodiments of the present invention is explained in detail in conjunction with attached drawing, but the utility model be not limited to it is described
Embodiment.For a person skilled in the art, in the case where not departing from the utility model principle and spirit, to these
Embodiment carries out a variety of change, modification, replacement and modification, still falls in the protection scope of the utility model.
