Description
Technical field
This utility model relates to the coupling arrangement technical field of borer drill rod, specifically one and prevents rig from falling to bore
Bar personality card.
Background technology
Drilling rod is to connect, in order to transmit the rod member of power in drilling tool.It is to pass through drilling rod between drilling rod and drilling rod
The flange at two ends is connected with each other, and realizes fastening by bolt.Operationally, the self gravitation of bolt drilling rod to be born
Effect, the load such as the moment of torsion produced when still suffering from work, moment of flexure, the most likely can cause bolt that the dangerous feelings such as fracture occur
The generation of condition, once bolt fracture, drilling rod will drop in well, and drilling rod is proposed to be an extremely difficult thing in well
Feelings, not only labor intensive, also result in work efficiency and reduce.So being badly in need of a kind of dress being capable of and preventing borer drill rod from dropping
Put.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, lower-cost, energy
Enough devices realizing preventing borer drill rod from dropping, i.e. one prevents rig from falling drilling rod personality card.
Technical problem to be solved in the utility model realizes by the following technical solutions:
One prevents rig from falling drilling rod personality card, including first quarter moon card, bearing pin and split pin, described first quarter moon card, bearing pin and
The quantity of split pin is two；Described first quarter moon card arranged on left and right sides is provided with engaging lug, is provided with pin-and-hole in the middle part of engaging lug, and described half
The moon is provided with groove inside blocking, and described groove upper and lower is equipped with positive stop lug boss；It is provided with through hole bottom described bearing pin；Described
Two first quarter moon cards are connected by bearing pin.During installation, first the flange of two drilling rods completing to connect is placed in the groove of first quarter moon card
Inner side, the groove then making two first quarter moon cards is relative, and two first quarter moon card engaging lugs are matched, then by bearing pin by two
Individual first quarter moon card is fixed together, and is positioned by bearing pin finally by split pin, and the positive stop lug boss of first quarter moon card is by the flange of two drilling rods
Spacing, in the case of the connecting bolt of drilling rod ruptures, it is ensured that drilling rod does not falls out.
Described split pin is arranged in through hole.Described bearing pin top end diameter is more than the diameter of pin-and-hole.
The composition surface flush of described first quarter moon card arranged on left and right sides engaging lug, and the composition surface court of institute of arranged on left and right sides engaging lug
Direction is the most relative.
The beneficial effects of the utility model are: this utility model has the advantages such as reasonable in design, cost be relatively low.Work as brill
During connecting bolt complete rupture between bar and drilling rod, this utility model is prevented from being positioned at the drilling rod of lower section and drops at well.
During additionally, use, first quarter moon card has interchangeability, uses and keeps in repair more convenient, and this utility model is lightweight, easy for installation,
Alleviating the labor intensity of people, the work well for drilling rod provides safeguard, and can be effectively improved production efficiency.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
In the face of this utility model is expanded on further.
As shown in Figures 1 to 4, one prevents rig from falling drilling rod personality card, including first quarter moon card 1, bearing pin 2 and split pin 3,
The quantity of described first quarter moon card 1, bearing pin 2 and split pin 3 is two；Described first quarter moon card 1 arranged on left and right sides is provided with engaging lug 101, even
Being provided with pin-and-hole 103 in the middle part of lug 101, be provided with groove 102 inside described first quarter moon card 1, described groove 102 upper and lower is equipped with
Positive stop lug boss 104；It is provided with through hole 201 bottom described bearing pin 2；Described two first quarter moon cards 1 are connected by bearing pin 2, and opening
Pin 3 is arranged in through hole 201.
Described split pin 3 is arranged in through hole 201.Described bearing pin 2 top end diameter is more than the diameter of pin-and-hole 103.
The composition surface flush of described first quarter moon card 1 arranged on left and right sides engaging lug 101, and the connecing of arranged on left and right sides engaging lug 101
Conjunction face is the most relative towards direction.
During use, first the flange of two drilling rods completing to connect is placed in inside the groove 102 of first quarter moon card 1, then makes two
The groove 102 of individual first quarter moon card 1 relatively, and makes two first quarter moon card 1 engaging lugs 101 match, then by bearing pin 2 by two and half
Blocking 1 the moon to be fixed together, positioned by bearing pin 2 finally by split pin 3, the positive stop lug boss 104 of first quarter moon card 1 is by the method for two drilling rods
Blue spacing, in the case of the connecting bolt of drilling rod ruptures, two first quarter moon cards 1 are interconnected to form spacing annulus so that drilling rod
Do not fall out.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
