Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with detailed description of the invention.
First, alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the utility model.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
Secondly; the utility model utilizes structural representation etc. to be described in detail; when describing the utility model embodiment in detail; for ease of explanation; represent that the schematic diagram of drill bit structure can be disobeyed general ratio and be made partial enlargement; and described schematic diagram is example, it should not limit the scope of the utility model protection at this.In addition, the three dimensions of length, width and the degree of depth should be comprised in actual fabrication.
Refer to Fig. 1, a kind of drill bit described in the utility model, comprise cylinder body 9, mandrel 3, drill boom 7, connecting rod drill boom 10 and guide's drill bit 11, mandrel 3 is through cylinder body 9, one end of mandrel 3 is fixed with guide's drill bit 11, and guide's drill bit 11 is connected with cylinder body 9 by connecting rod drill boom 10 and drill boom 7, and mandrel 3 is connected with mandrel travel mechanism, mandrel travel mechanism promotes mandrel 3 and moves, and and then drill boom 7 is opened and gathering.
Mandrel travel mechanism can adopt the various mode such as hydraulic pressure, oil pressure, machinery, electronic, air pressure, and the most frequently used is adopt water under high pressure.
The mandrel travel mechanism of water under high pressure is adopted to comprise water vat bar 8 and rodless cavity 12, water vat bar 8 is slidably fitted between cylinder body 9 and mandrel 3, rodless cavity 12 is between water vat bar 8 and cylinder body 9, water vat bar 8 is provided with the interlock screw 6 of band moving mandrel 3 movement, rodless cavity 12 communicates (see Fig. 3) with outer water channel 16.Mandrel 3 is provided with keyway, and interlock screw 6 is slidably fitted in keyway.
In order to lock drill bit, cylinder body 9 being provided with the tongue back-moving spring 4 of tongue 5 and compression tongue 5, water vat bar 8 being provided with the cammed surface of agreeing with mutually with tongue 5.Tongue 5 is provided with a step surface, and mandrel 3 is engaged with tongue 5 by this step surface.
The other end of mandrel 3 is fixed with interior connector 2, cylinder body 9 is fixed with the outer connector 1 around interior connector 2, forms annular space between outer connector 1 and interior connector 2.Outer connector 1 and interior connector 2 are connected with interior bar 15 with the outer bar 14 of double-wall drill pipe respectively.
Operating principle of the present utility model is as follows:
Drill bit is opened:
As shown in Figure 3, that be connected with drill bit is double-wall drill pipe (see Fig. 2), water under high pressure 17 enters drill bit from the annular space of double-wall drill pipe (i.e. the outer bar 14 of double-wall drill pipe formed with interior bar 15 annular gap), the outer water channel 16 entering drill bit by outer connector 1 and the annular space of interior connector 2 enters the rodless cavity 12 in Fig. 1, promote water vat bar 8 to be moved to the left, water vat bar 8 promotes tongue 5 by the cammed surface of agreeing with mutually with tongue 5 and moves upward, tongue 5 is provided with a step surface, mandrel 3 is engaged with tongue 5 by this step surface, after tongue 5 moves up to and is separated with mandrel 3, water vat bar 8 continues to push ahead to interlock screw 6 and withstands mandrel 3, then band moving mandrel 3 is continued to left movement.Mandrel 3 is provided with a keyway, interlock screw 6 can slidably reciprocate in this keyway.Now mandrel 3 low order end is connected with guide's drill bit 11, guide's drill bit 11 and connecting rod drill boom 10, connecting rod drill boom 10 is connected with drill boom 7, so guide's drill bit 11 will be driven when mandrel 3 is moved to the left to be moved to the left, thus drill boom 7 and connecting rod drill boom 10 are expanded outwardly, now drill bit is exactly open mode.
Drill bit draws in:
As shown in Figure 3, double-wall drill pipe is ined succession drill bit, (now the rodless cavity 12 of outer water channel 16 is cancelled) water under high pressure 17 enters into by the centre bore of bar 15 on double-wall drill pipe the enclosure space that interior connector 2 formed with interior bar 15, and produce pressure, interior connector 2 is moved right, the mandrel 3 be threaded with interior connector 2 also together with move right, because water vat bar 8 and mandrel 3 are fixed by the screw 6 that links, water vat bar 8 also moves right, guide's drill bit 11 that mandrel 3 drives low order end to connect simultaneously moves right, so the drill boom 7 be connected with guide's drill bit 11, connecting rod drill boom 10 is also regained, because rodless cavity 12 pressure of at this time outer water channel 16 is cancelled, water vat bar 8 also moves right, water vat bar 8 is fixed by the screw 6 that links with mandrel 3, mandrel 3 also moves right, when water vat bar 8 exits tongue 5 position, tongue 5 is closed by tongue back-moving spring 4, mandrel 3 cannot be moved to the left, drill bit draws in and pins, in order to avoid drill bit is opened by mistake.
What the those of ordinary skill in affiliated field should be understood that is, one of feature of the present utility model or object are: a kind of drill bit of the present utility model, there is converging angles scope of compromise large, stressed equal power, structural strength is large, and the simple feature of structure, can meet the requirement of various boring, reaming, first aperture can be completed after arrival requires the degree of depth, then bore the requirement of macropore.Static pile press of the present utility model is installed, can be entered by stake endoporus at need in piling and carry out holing and ream operation, make traditional silent piling function be applied in the occasion of not easily piling, expand the scope of application of static pile press.
It should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
