Because gas emission in coal mine is very large, when being difficult to dilution eliminating by ventilation, the method for available extraction, gets rid of gas, reduces burden of ventilating.Often need to adopt gas extraction blower to get rid of gas, and in use installation process, need to adopt coupling shaft, existing coupling shaft when being arranged on rig gearbox due to design structure adopt be that the mode offering a circle tapped hole at collapsable shaft disk place is fixed, in use dismantle trouble, the collapsable shaft ubiquity simultaneously thought problem be exactly in use connecting screw easily rupture, working life is short.
Summary of the invention
The object of the invention is, for solving the problem that the dismounting of existing transmission shaft bothers and working life is short, to provide a kind of coupling shaft of coal mine gallery drilling rig gas extraction blower.
The present invention is the deficiency solved the problems of the technologies described above, and the technological scheme adopted is:
A kind of coupling shaft of coal mine gallery drilling rig gas extraction blower, comprise a collapsable shaft, collapsable shaft coordinates section by the rig for connecting rig gearbox successively, for the disk segments of transmitting torque, connect and compose for the blower construction section of installing blower and the tapered thread section that is connected with drilling rod, the outer wall of described rig cooperation section is milled with six homalographics and coordinates section outer wall one week equally distributed plane along rig, section is coordinated away from one end of disk segments offers tapped hole so that be fixed on by coupling shaft on rig gearbox at rig, one end of disk segments coordinates section to be connected by changeover portion I with rig so that form the location shaft shoulder that rig coordinates section, the other end of disk segments is connected so that form the location shaft shoulder of blower construction section by changeover portion II with blower construction section, tapered thread section is connected with one end of blower construction section by changeover portion III, fixed card slot is provided with so that fixing blower between blower construction section and changeover portion III, blower construction section offers the radial hole radially distributed, coupling shaft also offers one section through blower construction section, axial bore in changeover portion III and tapered thread section, radial hole is communicated with axial bore so that the hearsay in blower delivered in drilling rod.
Described disk, changeover portion II, blower construction section, changeover portion I and rig coordinate the diameter of section to reduce successively.
The diameter of described changeover portion III and the diametric fit of blower construction section, can adopt same diameter.
The distance of shaft shoulder place, the location plane of the distance between center line blower construction section of described radial hole is the 1/6-1/2 of blower construction section length.
The center line of described axial bore overlaps with the center line of described coupling shaft.
The invention has the beneficial effects as follows: realization of the present invention is connected with the quick of rig gearbox, changing left and right bolt fastening structure is left-right integrated formula structure, frequent demounting bolt and fracture of wire phenomenon are stopped, intensity and the life-span of coupling shaft significantly improve, improve working efficiency, alleviate the labor intensity of miner.
The present invention is by the Shang Xiliu of cylndrical surface, form the rig coordinated with the mounting hole of rig gearbox and coordinate section, can realize inserting fast or extracting, a large amount of like this decreases the installation and removal time, be provided with the location shaft shoulder simultaneously and can determine mounting point easily, and coordinate installation to ensure axial restraint by the tapped hole of axle head.Such design eliminates middle connecting bolt, stop the phenomenon that original bolt fractures because of the shearing stress be subject to, thus improve the working life of whole transmission shaft, be provided with multistage simultaneously and blower can be installed and the axial bore and the radial hole that are provided with cooperation, achieve and the hearsay of blower is delivered to a formation air channel in drilling rod.
