By the present invention, be slowly shifted up and down owing to employing screw shell, thus can by transmission cylinder relative to drilling rod slowly movement, the most flexible alignment pin is slowly positioned in circumferential locating slot, thus avoids excess impact and cause shape and structure impaired.Due to the design feature of keyway and top pressure spring, whole drilling rod and transmission cylinder can float in certain axial range, and the axial load in boring procedure can be provided by the effect of epirelief cylindrical portion and blind hole inwall or be offset; Circumferential load is then by keyway and spline structure carrying.Wearing and tearing are produced in order to avoid drilling rod when contacting with driving shaft by arranging wearing layer at blind hole upper wall, top pressure spring also can not produce with driving shaft and rub in long-time use, avoid the wearing and tearing of driving shaft and drilling rod, arrange petroleum pipeline by the right and left in driving shaft to be connected with the keyway of blind hole, for carrying lubrication oil in keyway, increase lubricity, thus ensure that the shell portion of transmission cylinder stably slides in keyway.Whole apparatus structure is simple, easy to operate, uses reliable.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the drilling equipment with wearing layer and petroleum pipeline of the present invention.
Detailed description of the invention
By reference to the accompanying drawings 1, detailed explaination is made to the present invention.
According to embodiment, a kind of drilling equipment with wearing layer and petroleum pipeline, comprise housing 9 and be positioned at the driving shaft 8 of housing 9, the lower end of described driving shaft 8 is provided with the blind hole with keyway 81, described blind hole upper wall is provided with wearing layer 44, the thickness of described wearing layer 44 is 2mm, in described driving shaft 8, the right and left is provided with petroleum pipeline 55 and is connected with the keyway 81 of described blind hole, be slidably matched with the keyway 81 of described blind hole outside the shell portion 62 of transmission cylinder 6, internal spline is provided with in order to coordinate with the external splines outside the radial enlargement 71 of drilling rod 7 inside the described shell portion 62 of described transmission cylinder 6, described transmission cylinder 6 the portion integral formula of described shell portion 62 be provided with outstanding cylindrical portion 61 in order to threaded engagement side engagement in the lower end cylindrical portion 91 of described housing 9 and in the lower end wall 51 of the screw shell 5 be shifted up and down, thus described transmission cylinder 6 is shifted up and down in described blind hole, top pressure spring 4 is provided with thus by described transmission cylinder 6 biased downward between the end wall 63 of the perforate arranged in the top institute integral type of the described shell portion 62 of described transmission cylinder 6 and the inner end wall of described blind hole, the downside of the described shell portion 62 of described transmission cylinder 6 is provided with location shoulder 620 in order to engage with the stopper section, location 810 of the lower end being arranged on described keyway 81, the multiple radial expansion alignment pins 631 arranged in described end wall 63 can extend out to carry out axial location with the circumferential detent engagement in the epirelief cylindrical portion 72 of the described drilling rod 7 extend in described perforate thus to described drilling rod 7 in the perforate of end wall 63 under the effect of biased element, and described epirelief cylindrical portion 72 is adjoined with described radial enlargement 71 and diameter is less than described radial enlargement 71.
Alternatively, wherein, the end of described radial expansion alignment pin 631 is provided with and skids off inclined-plane to coordinate with the inclined surface of described circumferential locating slot thus can skid off from described circumferential locating slot.
Alternatively, wherein, the upper end of described epirelief cylindrical portion 72 is provided with inclined plane part 720 in order to lead when engaging with described radial expansion alignment pin 631.
During use, original state is that screw shell 5 is at upper position, thus transmission cylinder 6 and top pressure spring 4 are operated in compression position, when drilling rod 7 installed by needs, inserted by drilling rod 7, make upper end withstand on the wearing layer 44 of blind hole upper wall, then turn screw shell 5 makes it slowly move down, transmission cylinder 6 slowly moves down under the effect of top pressure spring 4 and flexible alignment pin 631 slowly stretches in circumferential locating slot, thus realizes drilling rod installation; When needs unload drilling rod 7, move on screw shell 5 turn is slow, thus make transmission cylinder 6 and top pressure spring 4 be in compression position gradually, simultaneous retractable alignment pin 631 slowly skids off circumferential locating slot, thus is unloaded by drilling rod.
