Abstract
The utility model relates to a drill rod connecting device which comprises a shell (7), spring seats (2), a spring (3), a clamping block (4), a control block (6) and buttons (5), wherein the shell (7) is provided with a through hole with the angle of 90 degrees, the buttons (5) are respectively arranged in a group of through holes with the angles of 180 degrees, and the spring seats (2) are respectively arranged in another group of through holes with the angles of 180 degrees; the spring seats (2) are connected with the shell (7) in a detachable way, a convex shaft arranged at the other end of the spring seat (2) is arranged inside a cavity of the clamping block (4), and the spring (3) is arranged on the convex shaft of the spring seat (2) and between the spring seat (2) and the clamping block (4); the clamping block (4) and the control block (6) are arranged inside a round inner cavity of the shell (7), the clamping block (4) is connected with an inclined plane of the control block (6) which is fixedly connected with the buttons (5); therefore, the time for butt joint is short, and the drilling efficiency is high.
Description
One, technical field
The utility model relates to a kind of drilling rod linkage, especially a kind of drilling rod linkage of two drilling rods that can be dynamically connected certainly.
Two, background technology
In all kinds of rigs, for reaching (common tens meters of predetermined drilling depths, even hundreds of rice), depending merely on a drilling rod can't realize, general all is that a joint run of steel is controlled within the suitable scope, by successively a connection, reaches the predetermined dark purpose of boring again, rig formula coal-winning machine also is need link together a section drilling rod equally, so the drilling rod linkage is necessary; In existing drilling rod linkage, mostly be to use thread connection and two drilling rods are linked together, its docking time is long with drilling time relatively, and the drilling process required time is than lacking about 2～5 minutes usually, docking time is about 7～10 minutes, thereby has influenced the operating efficiency of creeping into.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model provides a kind of drilling rod linkage; Docking time is short, the drilling efficiency height.
For achieving the above object, the technical scheme that the utility model is taked is: include shell, spring base, spring, clamp, controll block and button, between being provided with, shell is 90 ° through hole, button is separately positioned on one group and is in 180 ° the through hole and spring base is separately positioned on another group and is in 180 ° the through hole, spring base is set to connect with shell is detachable, the protruding axle of the spring base other end is arranged in the cavity of clamp, spring is arranged on the protruding axle of spring base and goes up and be arranged between spring base and the clamp, clamp and controll block are arranged in the round cavity of shell, clamp is set to connect with the controll block inclined-plane, and controll block is set to be fixedly connected with button.
Inwardly promote button, under ramp effect between controll block and the clamp, drive controll block moves inward clamp is outwards moved, make the diameter of two clamps become big, when drilling rod being placed between two clamps, release button, clamp is under the effect of spring, move inward drilling rod is clamped, controll block is outwards moved, make button projecting inward again, when inwardly promoting button once more from shell, make the diameter of two clamps become big again, can take out drilling rod.Therefore docking time is short, the drilling efficiency height.
The utility model has designed, on the shell cross central line and longitudinal centre line be provided with through hole, button is separately positioned in the through hole of cross central line of shell, spring base is arranged in the through hole of longitudinal centre line of shell.Make clamp and controll block spaced apart each other.
The utility model has designed, and clamp and controll block are set to a circumference that center with the round cavity of shell is the center of circle and the cut-off rule between it by its center of circle.Make between clamp and the controll block and connect for the inclined-plane.
The utility model has designed, and also includes snap ring, and snap ring is arranged on the recess of spring base and the recess of outer casing through hole, and spring base is connected with shell.Maintenance and maintenance have been made things convenient for to spring base and spring.
Four, description of drawings
Accompanying drawing is the utility model schematic diagram.
Five, the specific embodiment
Accompanying drawing is an embodiment of the present utility model, specify present embodiment in conjunction with the accompanying drawings, include shell 7, spring base 2, spring 3, clamp 4, controll block 6, button 5 and snap ring 1, be provided with through hole with longitudinal centre line on shell 7 cross central lines, button 5 is separately positioned in the through hole of cross central line of shell 7, spring base 2 is arranged in the through hole of longitudinal centre line of shell 7 and is arranged on the recess of spring base 2 and the recess of shell 7 through holes is set to connect with shell 7 by snap ring 1, the protruding axle of spring base 2 other ends is arranged in the cavity of clamp 4, spring 3 is arranged on the protruding axle of spring base 2 and goes up and be arranged between spring base 2 and the clamp 4, clamp 4 and controll block 6 are arranged in the round cavity of shell 7, clamp 4 and controll block 6 are set to a circumference that center with the round cavity of shell 7 is the center of circle and the cut-off rule between it by its center of circle, and controll block 6 is set to be fixedly connected with button 5.
Inwardly promote button 5, drive controll block 6 moves inward clamp 4 is outwards moved, make the diameter of two clamps 4 become big, when drilling rod being placed between two clamps 4, release button 5, clamp 4 move inward drilling rod are clamped under the effect of spring 3, controll block 6 is outwards moved, make button 5 projecting inward again from shell 7.
When using present embodiment, spring base 2 is snapped fit onto on the shell 7 by snap ring 1; Maintenance and maintenance have been made things convenient for to spring base 2 and spring 3.Connect with inclined-plane between the controll block 6 by clamp 4; By controll block 6 clamp 4 inwardly or is outward moved, made things convenient for clamping or disconnection drilling rod.
In drilling rod linkage technical field, all clamps 4 that includes connect with controll block 6 inclined-planes, make technology contents that clamp 4 moves all in protection domain of the present utility model by spring 3.
