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.By being connected in order to carry out positioning and guiding to the installation of drilling rod of limited block and limited impression, preventing drilling rod in installation and unload in process and occur skew.Whole apparatus structure is simple, easy to operate, uses reliable.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of drilling equipment that can be spacing 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 can be spacing drilling equipment, 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, 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 in the perforate of end wall 63 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 under the effect of biased element, described epirelief cylindrical portion 72 is adjoined with described radial enlargement 71 and diameter is less than described radial enlargement 71, the upper wall centre position of described blind hole is fixedly installed limited block 74, be provided with the limited impression 75 matched with described limited block 74 in described epirelief cylindrical portion 72 and position guiding in order to extend in described perforate described drilling rod 7, described limited impression 75 is square deep gouge.
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, drilling rod 7 is inserted, is inserted in limited impression 75 by limited block 74 and guiding is positioned to drilling rod 7, when drilling rod 7 upper end withstands on blind hole upper wall, then turn screw shell 5 makes it slowly move down, and 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, limited block 74 stretches out limited impression 75 gradually simultaneously, flexible alignment pin 631 slowly skids off circumferential locating slot, thus is unloaded by drilling rod.
Above embodiment is just for explanatory information of the present invention, and the scope of not intended to be limiting the claims in the present invention.
