Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the purpose of this utility model is the multistage connection expansion automatic locking bar water booster system being provided for Spiral digging machine drilling rod, comprise the first motor 1, second motor 2, large arm 32, the coaster 31 be slidably connected with large arm 32, the urceolus 5 be connected with coaster 31 and the inner core 6 be sheathed in urceolus 5, described urceolus 5 is connected with rotary power head 3, described urceolus 5 can move up and down in rotary power head 3, described coaster 31 is connected with the second motor 2 by chain, described inner core 6 internal fixtion is provided with inner core stopping means, described first motor 1 is connected with inner core stopping means by wire rope 4, interior buckle is also provided with in described inner core, first through hole 16 corresponding with interior buckle is provided with in described inner core, described urceolus is also provided with the second through hole 17 matched with the first through hole 16, the bottom outer wall of described urceolus 5 is also provided with at least one hook 13, described inner tank theca is provided with the groove 18 that at least one matches with hook hook portion, described hook 13 adopts extension spring 14 to be fixed on outer tube wall.In the utility model, the lower end of inner core is connected with drill bit, when inner core does not work, inner core is the position being fixed on top in urceolus by inner core stopping means, inner core stopping means is all separated setting with inner core with urceolus, when the first motor rotates inner core stopping means toward transferring, now inner core also down moves with inner core stopping means due to self gravitation, when inner core down extends to bottom urceolus, hook hook portion just hooks groove, but because inner core weight is large, although therefore inner core be hook up to by hook, but can continue to haul hook and down move, until interior buckle tips the first through hole in and the second through hole makes inner core and urceolus be fixed together, inner core just stops down moving, now the first motor quits work.Then start the second motor to rotate, coaster is connected with the second motor by chain, coaster is fixedly connected with urceolus, and when chain pulls down coaster, coaster is also toward pressing down urceolus, coaster being equipped with pulley can at the slide on rails of large arm, because urceolus is fixedly connected with inner core, therefore the drill bit of drilling rod is just applied in pressure on ground hole to be drilled, and rotary power head task driven urceolus rotates simultaneously, inner core also follows urceolus to rotate together, and inner core also drives drill bit to implement boring work; When stopping boring work when needing the earth in hole to transport out, second motor quits work, and now the first motor reversely rotates, by inner core stopping means toward pull-up, thus drive inner core up to move, now, buckle disengaging urceolus up moves with inner core.The utility model structure is simple, easy to operate.In the utility model, the least significant end that wire rope connects inner core stopping means is equipped with bearing, wire rope non rotating when such inner/outer tube rotates thus avoid twisting off wire rope.
As the utility model preferred embodiment, described inner core and urceolus are box section, because the rotation of drill bit is outer cylinder drive inner cylinder rotating, if depend interior buckle alone to fix inner core and urceolus, then give the operating pressure of interior buckle too large, because interior buckle had both carry inner core weight, drive inner cylinder rotating again simultaneously, therefore, inner core and urceolus are designed to box section, when such urceolus drives inner cylinder rotating, easy by what become very.
As the embodiment that the utility model is concrete, described hook 13 arm is also provided with projection 15, this projection 15 is supported on urceolus 5 outer wall, hook adopts such structure to be interior buckle-like in urceolus lower end, therefore when inner core 6 moves downward bottom, hook also just hooks groove 18, this hook 13 can projection 15 be fulcrum, the hook portion external surface of described hook is arcwall face, and when inner core will move upward, the lower cell wall of groove can back down hook hook portion to be made hook hook portion flick outward thus makes groove leave hook, hook hook portion external surface be arcwall face then groove back down hook better.
Described interior buckle comprises locking bar 9, support slipper 10 and spring 8, described spring one end is fixedly connected with locking bar one end, spring 8 other end is fixed on a support 7, the other end cross section of described locking bar is less than the cross section of the first through hole, the other end cross section of described locking bar is less than the cross section of the second through hole, the other end of locking bar is all less than the cross section of the first through hole and the second through hole, such locking bar could insert the first through hole and the second through hole, described locking bar is connected Cheng “ I with support slipper " font, described support is fixedly installed on inner core.Described inner core stopping means 12 comprises at least one oblique top 121, described oblique top 121 is right-angled trapezium shape, described support slipper 10 contacts with the inclined-plane of oblique top 12, in the process that inner core up or down moves, oblique top always is withstands support slipper, because support slipper is connected with locking bar, therefore locking bar pressing spring always, when inner core is linked up with, oblique top also can a little down be moved, oblique top is down in motion process, withstand support slipper width more and more less, now, under the action of the spring, locking bar drives support slipper to move along the direction of the first through hole and the second through hole, until locking bar fastens the first through hole and the second through hole, reach the object of the multistage connection expansion automatic locking bar of Spiral digging machine drilling rod like this.When inner core will up move, first motor reversion drives inner core restraining position up namely to drive skewback up to move, the width withstanding support slipper due to skewback is increasing, namely support slipper is slowly away from inner core inwall, drive locking bar to leave the first through hole and the second through hole, such inner core restraining position just drives inner core up to move simultaneously.
Further, because skewback is except the effect of backing down back-up block, a main effect is also had to be exactly the weight that support inner core, if therefore support or locking bar are pushed up in the top of skewback, bring very large burden will to locking bar or support, therefore as a kind of preferred mode, at least one limited block is also provided with in inner core, described limited block 11 is arranged at the top of oblique top, described limited block 11 is arranged at the below of locking bar 9, such limited block can withstand skewback, namely bears the gravity that inner core is huge.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
