Abstract
The utility model relates to an elastic caliper on a drill rod. The elastic caliper is formed by rotatably connecting two identical pallets. The elastic caliper is characterized in that a convex part is arranged at one end of each pallet; a pin shaft hole is formed in the other end of each pallet; a slotted hole is formed in each convex part; a limiting flange is arranged on one side of each pallet; one ends of the two identical pallets are in rotational connection with each other through a pin shaft; the other ends are connected with the slotted hole in a sliding manner through a short column. The elastic caliper adopts a short shaft and the slotted hole to realize the closing and opening action of the pallets, detachment of the pallets is avoided, and the retraction reliability and working stability of the drill rod are improved.
Description
Technical field
The utility model relates to geological prospecting apparatus field, relates 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, for the ease of the length of drilling rod, regulates, and 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 makes to get loose between axle sleeve and clamp 1, and drilling rod loses stable, causes security incident.
Utility model content
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 scheme that the utility model adopts 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.
The beneficial effects of the utility model are as follows:
The utility model 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 utility model.
Fig. 4 is three-dimensional structure diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
See Figure 13 and Fig. 4, the utility model is rotationally connected and is formed by two identical clamps 4 cooperations; 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.
During the utility model work, short column 5 is connected in the axle sleeve (not shown) of drilling rod, and when axle sleeve pulls, short column 5 is in the interior rectilinear movement of waist-shaped hole 43, thereby drive clamp 4 to rotate and realize opening and closing action around bearing pin 6, defining flange 44 limits the opening angle of clamp 4.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of modification.
Claims (1)
