Rig, as a kind of drilling engineering machinery, because of its high efficiency, is used widely in engineering construction field.Affected by job site geological conditions, during borer drill rod driving, be generally complicated disturbance operating mode, therefore, borer drill rod adopts shaft coupling to be connected with tooth case clutch end, and as disclosed Chinese patent application CN102747968A on October 24th, 2012, it discloses a kind of down-the-hole drill drilling rod shaft coupling, comprise upper body and lower body, and for connecting the follower bolt assembly of upper body and lower body, make to be unlikely to depart between lower body, and guarantee the sealing of chip removal air duct.But it still has following deficiency: owing to being directly bolted between upper lower body, in boring procedure, due to the disturbance of drilling rod, in connection, the bolt of lower body need to bear shear stress, when disturbance is larger, even there will be the situation that bolt is twisted into two parts.
Utility model content
For solving above technical problem, the utility model provides a kind of connection reliable, can bear the borer drill rod shaft coupling of the larger disturbance of drilling rod.
Technical scheme is as follows:
A kind of borer drill rod shaft coupling, comprise the upper half a coupler and the lower half a coupler that are oppositely arranged, described upper half a coupler is provided with the projection for transmitting torque at the end face relative with lower half a coupler, on described lower half a coupler, be provided with the groove corresponding with described projection, described projection extend in groove, its key is: half a coupler and lower half a coupler are outside equipped with adapter sleeve on described, described adapter sleeve one end is fixedly connected with upper half a coupler, the other end is coated on lower half a coupler, and described lower half a coupler is connected with drilling rod tail end through adapter sleeve.
Adopt above structure, because adapter sleeve is enclosed within on lower half a coupler rotationally, make adapter sleeve there is certain degree of freedom with respect to lower half a coupler, when drilling rod generation disturbance, be unlikely to affect being connected between adapter sleeve and upper half a coupler.
Preferably, described lower half a coupler is hemispherical near the outer face of upper half a coupler, described adapter sleeve has the hemispherical accommodation section that holds described lower half a coupler, described accommodation section is concentric with the outer face hemispherical of lower half a coupler, adopt above structure, can make adapter sleeve be coated on reliably on lower half a coupler, guarantee upper and lower half a coupler transmitting torque reliably.
Preferably, described upper half a coupler has along the outward extending boss of diametric(al), described adapter sleeve is connected to boss one side, on described boss, be provided with axial bolt hole, be provided with counterbore corresponding to described bolt hole on adapter sleeve, described adapter sleeve is connected by bolt group with upper half a coupler, adopts above structure, has guaranteed that adapter sleeve is connected with the reliable of upper half a coupler.
Preferably, described upper half a coupler lower end is provided with deep gouge, described lower half a coupler upper end is provided with spherical groove, in deep gouge, be provided with flexible rubber, have centering hemisphere with spherical groove is chimeric, planar ends and the deep gouge bottom of centering hemisphere withstood respectively at the two ends of described flexible rubber, adopts above structure, can utilize the certralizing ability of sphere-contact, be drilling rod transferring axial thrust.
Beneficial effect: adopt the borer drill rod shaft coupling of above technical scheme, this novelty simple in structure, compactness, can realize the reliable connection of upper and lower half a coupler, avoids destroying connecting bolt because of drilling rod disturbance.
