Abstract
The invention relates to an elastic clamp for a drill rod. Two same clamp plates are rotatably connected in a matched manner to form the elastic clamp. The elastic clamp is characterized in that one end of each clamp plate is provided with an outer projection, the other end of each clamp plate is provided with a pin hole, slotted holes are formed in the outer projections, one side of each clamp plate is provided with a limit flange, the ends of the two same clamp plates on one side are rotatably connected by the aid of a pin, and the other ends of the same clamp plates are slidably connected with the slotted holes by the aid of a short column. The elastic clamp is simple in structure, the clamp plates are opened and closed by matching the short column with the slotted holes, looseness of the clamp plates is avoided, and telescopic reliability and working stability of the drill rod are improved.
Description
Technical field
The present invention relates to geological prospecting apparatus field, relate in particular to the syndeton of drilling rod on rig.
Background technology
Rig is requisite equipment in geological prospecting, and the drilling rod on rig is cylindricality strip structure, and for the ease of the length adjusting of drilling rod, drilling rod operated by rotary motion can become stretching structure.The stretching structure of existing drilling rod is realized by playing clamp, see Fig. 1 and Fig. 2, playing clamp consists of two clamps 1, thinning area 12 and pin shaft hole are set on clamp 1, the end sides of clamp 1 arranges torsional spring slot 11, after two clamps 1 coordinate by thinning area 12 contacts, pin shaft hole aligns rear insertion bearing pin 2, and in the interior device torsion spring 3 of torsional spring slot 11; When drilling rod need to stretch, the axle sleeve on drilling rod promotes clamp 1 and rotates around bearing pin 2, and the effect of torsion spring 3 provides outside elastic force that clamp 1 is fixed near axle sleeve.The shortcoming of this bullet clamp is when drilling rod High Rotation Speed, and torsion spring 3 is easily from the interior disengaging of torsional spring slot 11, thereby axle sleeve and 1 of clamp are got loose, and drilling rod loses stable, causes security incident.
Summary of the invention
The above-mentioned shortcoming that the applicant exists for the bullet clamp on existing drilling rod, studies and improves, and the clamp of the bullet on a kind of drilling rod are provided, and has improved flexible reliability and the job stability thereof of drilling rod.
The technical solution adopted in the present invention is as follows:
Bullet clamp on drilling rod, are coordinated to be rotationally connected by two identical clamps to form, and it is characterized in that: one end of described clamp has male part, and its other end has pin shaft hole, and described male part place arranges waist-shaped hole; One side of clamp has defining flange; One end of two identical described clamps is rotationally connected by bearing pin, and the other end is by the short column described waist-shaped hole that is slidably connected.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, adopts minor axis to match with waist-shaped hole and realizes the opening and closing action between clamp, has avoided getting loose between clamp, has improved flexible reliability and the job stability thereof of drilling rod.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of the clamp of existing bullet clamp.
Fig. 2 is the three-dimensional structure diagram of existing bullet clamp.
Fig. 3 is the three-dimensional structure diagram of clamp of the present invention.
Fig. 4 is three-dimensional structure diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 3 and Fig. 4, the present invention is rotationally connected and is formed by 4 cooperations of two identical clamps; One end of clamp 4 has male part 42, and its other end has pin shaft hole 41, and described male part 42 places arrange waist-shaped hole 43; One side of clamp 4 has defining flange 44; One end of two identical described clamps 4 is rotationally connected by bearing pin 6, and the other end is by the short column 5 described waist-shaped hole 43 that is slidably connected.
When the present invention works, short column 5 is connected in the axle sleeve (not shown) of drilling rod, and when axle sleeve pulls, short column 5, at the interior traveling priority of waist-shaped hole 43, moves thereby drive clamp 4 to realize opening and closing around bearing pin 6 rotations, and defining flange 44 limits the opening angle of clamps 4.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of modification.
