Abstract
The utility model discloses a plug drill rod connecting sleeve which is characterized by comprising an inner joint, an outer joint and a fixed sleeve, the lower section of the inner joint is connected with a lower drill rod in a threaded manner, the upper section of the outer joint is connected with an upper drill rod in a threaded manner, the upper section of the inner joint is embedded into a barrel of the lower section of the outer joint, and the fixed sleeve is arranged between the inner joint and the outer joint to implement longitudinal limiting. The drill rods are connected by the aid of a nested structure and can be lengthened and disassembled only by plug, and the process is handy and convenient.
Description
Technical field
The utility model relates to a kind of jumbolter drilling rod linkage, is applied to the colliery shaft and drift supporting.
Background technology
When coal mine roadway adopts anchor pole, cable bolting, need be to the roadway surrounding rock internal drilling.Its drilling machine comprises rig, drilling rod and drill bit etc.Drilling rod is fixed length.In order to creep into the boring of different depth, need the spreading drilling rod, namely connect the drilling rod of different radicals according to the degree of depth of holing.Connect by adapter sleeve between each root drilling rod; It is more dark to hole, and the drilling rod radical that connects is more many; After every brill was finished a boring, the drilling rod that needs to connect unloaded from its adapter sleeve, spreading drilling rod during for follow-up boring.
At present, all adopt thread connection between employed drilling rod and the adapter sleeve in the boring of China's coal-mine tunnel.Because drilling rod bears and transmitting bigger moment of torsion when rig creeps into, the screw thread tight engagement between each adapter sleeve and the drilling rod makes that the dismounting of adapter sleeve and drilling rod is very difficult.For this reason, have to use iron hammer hammering drilling rod adapter sleeve repeatedly, drilling rod could be screwed off after the screw thread of its engagement is unclamped.It is more dark to hole, and the drilling rod radical of required dismounting is more many, wastes time and energy.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of plug-in drilling rod adapter sleeve being provided, so that the connection of drilling rod dismounting is light and handy convenient.
The utility model adopts following technical scheme for the technical solution problem:
The design feature of the utility model plug-in drilling rod adapter sleeve is to arrange:
One spigot, its spigot hypomere are the internal thread segment that is connected with the subordinate drill rod thread, the spigot epimere be in cylindrical periphery radially symmetry stretch a pair of segment, spigot stage casing and described spigot hypomere are formed with the spigot shaft shoulder;
One socket, its socket epimere is to be connected with higher level's drill rod thread with internal thread, the socket hypomere is for having externally threaded cylindrical shell, the internal cavities of institute's cylindrical shell is the fan-shaped cavity that the segment with described spigot epimere matches, so that in the fan-shaped cavity of the segment of described spigot epimere intercalation vertically in described socket hypomere;
One fixed cover, its fixed cover hypomere slides on the spigot hypomere, and its fixed cover epimere is to be threaded with the external screw thread of internal thread with the socket hypomere; Surely overlapping the middle part at described circle has one in the ring boss, described in the ring boss be to be the lower limit end face with the described spigot shaft shoulder, the segment in the described spigot is to encircle the upper surface of boss in the bottom end face with segment is butted on.
The design feature of the utility model plug-in drilling rod adapter sleeve also is: the central angle of the segment in the described spigot epimere is set to 90 °.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model adopts nesting type structure to realize that drilling rod connects, and the drilling rod connector transmits rig by the segment contacts side surfaces and creeps into moment of torsion, only needs plug can realize spreading and the dismounting of drilling rod, has overcome the difficulty that the jumbolter drilling rod is difficult to dismantle;
2, the utility model fixed cover of adopting end constraint, the other end can carry out thread connection carries out the longitudinal restraint between higher level's drilling rod and the subordinate's drilling rod, this constraint makes the screw thread in the fixed cover not stress when drilling rod rotates, and drilling rod connects and outwards winding conveniently light and handy.

Number in the figure: 1a spigot hypomere, 1b spigot epimere, 1c spigot stage casing, 1d segment, 2a socket epimere, 2b socket hypomere, 3a fixed cover hypomere, ring boss in the 3b fixed cover epimere, 3c, 4a higher level's drilling rod, 4b subordinate drilling rod.
The specific embodiment
Referring to Fig. 1 a, Fig. 1 b and Fig. 2, the form of structure of plug-in drilling rod connector is to arrange in the present embodiment:
One spigot, its spigot hypomere 1a are the internal thread segment that is threaded with the drilling rod 4b of subordinate, and spigot epimere 1b is the radially symmetrical a pair of segment 1d of stretching, extension in cylindrical periphery, and the central angle of segment 1d is set to 90 °; Spigot stage casing 1c and spigot hypomere 1a are formed with the spigot shaft shoulder.
One socket, its socket epimere 2a is threaded with higher level's drilling rod 4a with internal thread, socket hypomere 2b is for having externally threaded cylindrical shell, the internal cavities of cylindrical shell is the fan-shaped cavity that the segment with spigot epimere 1b matches, so that in the fan-shaped cavity of the segment of spigot epimere intercalation vertically in the cylindrical shell of socket hypomere.
One fixed cover, its fixed cover hypomere 3a slides on the spigot hypomere, and its fixed cover epimere 3b is threaded with the external screw thread of internal thread with the socket hypomere; At the fixed cover of circle middle part ring boss 3c one in is arranged, interior ring boss 3c is to be the lower limit end face with the spigot shaft shoulder, and the segment 1d in the spigot is the upper surface of encircling boss 3c in the bottom end face with segment is butted on.
Referring to Fig. 3 a and Fig. 3 b, the spreading drilling rod is that spigot is connected with the subordinate drill rod thread, and socket is connected with higher level's drill rod thread, the spigot epimere is inserted in the cylindrical shell of socket hypomere vertically again, fixed cover is threaded with socket namely finishes at last; The process of dismounting drilling rod is the inverse operation of spreading drilling rod process.
