Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, it is an object of the invention to provide for the multistage of rotary digging driver drilling rod
Connection expansion automatic locking bar pressue device, including the first motor 1, the second motor 2, large arm 32, and the cunning that is slidably connected of large arm 32
Car 31, and the connection of coaster 31 outer tube 5 and the inner core 6 being sheathed in outer tube 5, the outer tube 5 is connected with rotary power head 3,
The outer tube 5 can be moved up and down in rotary power head 3, and the coaster 31 is connected with the second motor 2 by chain, the inner core
Inner core stopping means are fixedly installed in 6, first motor 1 is connected with inner core stopping means by steel wire rope 4, the inner core
Interior buckle is inside additionally provided with, first through hole 16 corresponding with interior buckle is provided with the inner core, is additionally provided with the outer tube
The second through hole 17 matched with first through hole 16, is additionally provided with least one hook 13, institute in the bottom outer wall of the outer tube 5
State and on inner tank theca, be provided with least one groove 18 matched with hook hook portion, the hook 13 is solid using extension spring 14
On outer tube wall.In the present invention, the lower end of inner core is connected with drill bit, and when inner core does not work, inner core is limited by inner core
Position device is fixed on the position of top in outer tube, and inner core stopping means are separately positioned with inner core and outer tube, when the first horse
Up to rotation by inner core stopping means toward decentralization, now inner core is also down moved with inner core stopping means due to self gravitation, when interior
When down extending to outer tube bottom, hook hook portion just hooks groove to cylinder, due to inner core weight it is big, although therefore inner core hung
Hook hook up to, but may proceed to haul hook and down move, and tipping first through hole and the second through hole in until interior buckle makes inner core
It is fixed together with outer tube, inner core just stops down moving, and now the first motor quits work.Then start the rotation of the second motor
Turn, coaster is connected with the second motor by chain, and coaster is fixedly connected with outer tube, and when chain pulls down coaster, coaster is also past
Outer tube is pushed, can be slided on the guide rail of large arm equipped with pulley on coaster, because outer tube is fixedly connected with inner core, therefore the brill of drilling rod
Head is just pressurized on ground hole to be drilled, while rotary power head task driven outer tube rotates, inner core also follows outer tube
Rotate together, inner core also drives drill bit to implement boring work；When need by the soil in hole transport out and stop boring work
When, the second motor quits work, and now the first motor is reversely rotated, by inner core stopping means toward pull-up, so as to drive inner core past
Upper motion, now interior buckle depart from outer tube and up move with inner core.Present configuration is simple, easy to operate.In the present invention
In, the least significant end of steel wire rope connection inner core stopping means is equipped with bearing, and when such inner/outer tube rotates, steel wire rope is not rotated so as to keep away
Exempt to twist off steel wire rope.
Used as the preferred embodiment of the present invention, the inner core and outer tube are rectangular tube, because the rotation of drill bit is to lean on
Outer tube drives inner cylinder rotating, if the inner buckle of light fixes inner core and outer tube, too big to the operating pressure of interior buckle, because
Interior buckle had both carry inner core weight, while and drive inner cylinder rotating, therefore, inner core and outer tube are designed to into rectangular tube, so
When outer tube drives inner cylinder rotating, will become very easily.
As specific embodiment of the present invention, on 13 arm of the hook, projection 15 is additionally provided with, the projection 15 is supported in
On 5 outer wall of outer tube, it is in interior buckle-like in outer tube lower end that hook adopts such structure, therefore when inner core 6 is moved downwardly to bottom
Hook also just hooks groove 18, and the hook 13 can be with projection 15 as fulcrum, and the hook portion outer surface of the hook is arc
Face, and when inner core will be moved upwards, the lower cell wall of groove can back down hook hook portion makes hook hook portion be flicked so that recessed outward
Groove leaves hook, and the hook portion outer surface linked up with is that then groove preferably backs down hook to arcwall face.
The interior buckle includes locking bar 9, support slipper 10 and spring 8, and the spring one end is fixedly connected with locking bar one end,
8 other end of spring is fixed on a support 7, and the other end cross section of the locking bar is less than the cross section of first through hole, the lock
Cross section of the other end cross section of bar less than the second through hole, the other end of locking bar are both less than the horizontal stroke of first through hole and the second through hole
First through hole and the second through hole could be inserted in section, such locking bar, and the locking bar is connected Cheng “ I with support slipper " font, it is described
Support is fixedly installed on inner core.The inner core stopping means 12 include at least one oblique top 121, and the oblique top 121 is right angle
Trapezoidal shape, the support slipper 10 are contacted with the inclined-plane of oblique top 12, during inner core up or is down moved, oblique top one
Straight is all to withstand support slipper, as support slipper is connected with locking bar, therefore locking bar pressing spring always, when inner core is hung
When hooking, oblique top also somewhat down can be moved, and oblique top is down in motor process, and it is less and less to withstand support slipper width, now,
Under the action of the spring, locking bar drives support slipper to move along the direction of first through hole and the second through hole, until locking bar clasps the
Till one through hole and the second through hole, the purpose of the multistage connection expansion automatic locking bar of rotary digging driver drilling rod has so been reached.Work as inner core
When up moving, the reversion of the first motor drives inner core restraining position up namely to drive skewback up to move, due to skewback
The width for withstanding support slipper is increasing, that is, support slipper is slowly away from inner core inwall, while driving locking bar to leave the
One through hole and the second through hole, such inner core restraining position just drive inner core up to move.
Further, as skewback is in addition to the effect for backing down support block, also one main effect is exactly to support
The weight of inner core, so if very big burden will be brought to locking bar or support to support or locking bar in the top top of skewback,
Therefore as a kind of preferred mode, at least one limited block is additionally provided with inner core, the limited block 11 is arranged at oblique top
Top, the limited block 11 is arranged at the lower section of locking bar 9, and such limited block can withstand skewback, that is, bear inner core
Huge gravity.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
