Technical field
The present invention relates to boring field, especially a kind of drilling equipment led by guide post.
Background technology
With the drilling equipment of drill bit, its drill bit is removable often.Complicated manual operation is often needed in bit change-over process.This easily reduces operating efficiency, and may produce construction accident when misoperation.
And simplify in some device of replacement operation flow process for some, due to factors such as switching impulse power, its design of part easily damages, and causes shorten service life.
Summary of the invention
The present invention aims to provide a kind of drilling equipment led by guide post, and it can overcome the problems referred to above.
According to the present invention, a kind of drilling equipment led by guide post, comprise housing and be positioned at the driving shaft of housing, the lower end of described driving shaft is provided with the blind hole with guide post, the right and left of the shell portion of transmission cylinder is provided with pilot hole to be slidably matched with the guide post of described blind hole, internal spline is provided with in order to coordinate with the external splines outside the radial enlargement of drilling rod inside the described shell portion of described transmission cylinder, described transmission cylinder the portion integral formula of described shell portion be provided with outstanding cylindrical portion in order to threaded engagement side engagement in the lower end cylindrical portion of described housing and in the lower end wall of the screw shell be shifted up and down, thus described transmission cylinder is shifted up and down in described blind hole, top pressure spring is provided with thus by described transmission cylinder biased downward between the end wall of the perforate arranged in the top institute integral type of the described shell portion of described transmission cylinder and the inner end wall of described blind hole, the downside of the described shell portion of described transmission cylinder is provided with location shoulder in order to engage with the stopper section, location of the lower end being arranged on described guide post, the multiple radial expansion alignment pins arranged in described end wall can extend out to carry out axial location with the circumferential detent engagement in the epirelief cylindrical portion of the described drilling rod extend in described perforate thus to described drilling rod in the perforate of end wall under the effect of biased element, and described epirelief cylindrical portion and described radial enlargement adjoin and diameter is less than described radial enlargement.
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 guide post 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 guide post and spline structure carrying.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 led by guide post 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 led by guide post, 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 guide post 81, the right and left of the shell portion 62 of transmission cylinder 6 is provided with pilot hole 82 to be slidably matched with the guide post 81 of described blind hole, 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 guide post 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 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.
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.
