Abstract
The invention relates to a special drill rod clamp for preventing a drilling rig drill rod from dropping. The special drill rod clamp comprises half-moon clamps, pin shafts and cotter pins. The number of the half-moon clamps, the number of the pin shafts and the number of the cotter pins are all two. The left sides and the right sides of the half-moon clamps are provided with connecting lugs, pin holes are formed in the middle of the connecting lugs, the inner sides of the half-moon clamps are provided with grooves, and limiting bosses are arranged on the upper portions and the lower portions of the grooves. The bottoms of the pin shafts are provided with through holes. The two half-moon clamps are connected through the pin shafts, and the cotter pins are installed in the through holes. The two half-moon clamps are connected with each other to form a limiting ring, and on the conditions of breakage of a connecting bolt of the drill rod, it is guaranteed that the drill rod does not drop. During the use, the half-moon clamps have interchangeability and are convenient to use and maintain, it is guaranteed that the drill rod works smoothly, and the production efficiency can be effectively improved.
Description
Technical field
The present invention relates to the coupling arrangement technical field of borer drill rod, specifically one prevents rig from falling to bore
Drilling rod personality card.
Background technology
Drilling rod is to connect, in order to transmit the rod member of power in drilling tool.It is logical between drilling rod and drilling rod
The flange crossing two ends of drill is connected with each other, and realizes fastening by bolt.Operationally, bolt is not only wanted
Bear the self gravitation effect of drilling rod, the load such as the moment of torsion that produces when still suffering from work, moment of flexure, so have
May result in bolt and the generation of the dangerous situations such as fracture occur, once bolt fracture, drilling rod will drop
In well, drilling rod is proposed to be extremely difficult thing, not only a labor intensive in well, also results in work
Make efficiency to reduce.So being badly in need of a kind of device being capable of and preventing borer drill rod from dropping.
Summary of the invention
The technical problem to be solved is to provide a kind of reasonable in design, lower-cost,
Being capable of the device preventing borer drill rod from dropping, i.e. one prevents rig from falling drilling rod personality card.
The technical problem to be solved 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,
The quantity of bearing pin and split pin is two；Described first quarter moon card arranged on left and right sides is provided with engaging lug, in engaging lug
Portion is provided with pin-and-hole, is provided with groove inside described first quarter moon card, and described groove upper and lower is equipped with positive stop lug boss；
It is provided with through hole bottom described bearing pin；Two described first quarter moon cards are connected by bearing pin.During installation, first complete
The flange becoming two drilling rods connected is placed in inside the groove of first quarter moon card, then makes the groove phase of two first quarter moon cards
Right, and two first quarter moon card engaging lugs are matched, then by bearing pin, two first quarter moon cards are fixed together,
Being positioned by bearing pin finally by split pin, the positive stop lug boss of first quarter moon card, by the flange limiting of two drilling rods, is boring
In the case of the connecting bolt fracture of bar, 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 connecing of arranged on left and right sides engaging lug
Conjunction face is the most relative towards direction.
The invention has the beneficial effects as follows: the present invention 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, the present invention is prevented from being positioned at the drilling rod of lower section and drops
In well.During additionally, use, first quarter moon card has interchangeability, use with keep in repair more convenient, and weight of the present invention
Amount is light, easy for installation, alleviates the labour intensity of people, and the work well for drilling rod provides safeguard, and can have
Effect improves production efficiency.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the exploded perspective structural representation of the present invention；
Fig. 2 is the plan structure schematic diagram of the present invention；
Fig. 3 is the main TV structure schematic diagram of the present invention；
Fig. 4 is the main TV structure schematic diagram of the first quarter moon card of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect,
Below the present invention 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 is left and right
Both sides are provided with engaging lug 101, be provided with pin-and-hole 103, be provided with groove inside described first quarter moon card 1 in the middle part of engaging lug 101
102, 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 split 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 arranged on left and right sides engaging lug
The composition surface of 101 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, so
After make the groove 102 of two first quarter moon cards 1 relatively, and two first quarter moon card 1 engaging lugs 101 are matched, then
By bearing pin 2, two first quarter moon cards 1 are fixed together, finally by split pin 3, bearing pin 2 are positioned, first quarter moon card 1
Positive stop lug boss 104 by the flange limiting of two drilling rods, in the case of the connecting bolt of drilling rod ruptures, two
First quarter moon card 1 is interconnected to form spacing annulus so that drilling rod does not falls out.
The general principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The industry
Skilled person will appreciate that, the present invention is not restricted to the described embodiments, in above-described embodiment and specification
