Description
Technical field
The present invention relates to drilling tool is docked in a kind of horizontal directional drill down-hole, shake hands drilling tool particularly to a kind of cartridge type.
Background technology
After horizontal directional drill extra long distance completes docking to the project of passing through, the drill bit of both sides is simply met and discussed in underground, and
Cannot realize shaking hands.Under the precondition not having to draw, in bad ground, easily produce during the rotation propulsion of head rig side
Sink and depart from the hole guiding of auxiliary rig side, and drill new holes.If not rotating direct propulsion hardly possible is required to driller's operation
Degree greatly, is difficult to for main drill bit to be pushed out to auxiliary rig side ground.
Content of the invention
The technical problem to be solved is to provide a kind of cartridge type to hold for the deficiency that above-mentioned prior art exists
Hand drill has, and this drilling tool enables underground and shakes hands, and head rig side drilling tool is drawn so as to auxiliary drill can smoothly be reached
Machine side ground.
The technical solution adopted in the present invention is：A kind of cartridge type shake hands drilling tool it is characterised in that：Including outer shell barrel, outside
Be provided with multiple pull bars of shaking hands in thimble, described shake hands pull bar along outer shell barrel inwall circumferentially, one end of described pull bar of shaking hands
To the bending of outer shell barrel center position, the bending place of described pull bar of shaking hands and outer shell barrel inwall are hinged, and each is in be arranged oppositely
The bending end of pull bar of shaking hands is connected by spring, and the other end of the pull bar that makes to shake hands is be arranged in parallel with outer shell barrel inwall, is shaking hands
The other end of pull bar is provided with fixture block of shaking hands, and described fixture block of shaking hands is hinged with pull bar of shaking hands by torsion spring, described pull bar of shaking hands
Other end termination be connected with outer shell barrel also by limit spring, the front end of described outer shell barrel is closed by interim plug.
By technique scheme, in each shakes hands pull bar, corresponding fixture block setting of shaking hands is fluted, in the presence of external force,
Card of shaking hands is pushed in groove soon.
By technique scheme, the bending segment being located at pull bar of shaking hands in outer shell barrel is correspondingly provided with for guiding drill bit with outward
The concentric guide table of thimble, guide table is installed in outer shell barrel inwall, and described guide table is to be obliquely installed.
By technique scheme, the leading section being located at limit spring in outer shell barrel is installed with guided rings, described guided rings
Outer wall be in the little inverted cone shape of outer imperial palace.
By technique scheme, outer shell barrel axial direction is provided with multiple guided rings, described interim plug passes through guiding
The step of ring is fixed.
By technique scheme, it is provided with 4 pull bars of shaking hands in outer shell barrel.
During use, when opposite drill bit first destroy interim plug enter outer shell barrel internal when, enter when shaking hands pull bar, card of shaking hands
Block can be pushed into shakes hands in pull bar, and when opposite drilling tool can enter pull bar center of shaking hands, jacking pull bar of shaking hands is inside to it more afterwards
After contraction, the groove that the fixture block of shaking hands on pull bar of shaking hands will block on the drilling tool of opposite, and now limit spring ejects and withstands and hold
The hand lever pull bar that prevents from shaking hands unclamps, thus formed shaking hands.
Having the beneficial effect that acquired by the present invention：
1st, present configuration is simple and convenient to operate, and enables underground and shakes hands, and head rig side drilling tool is drawn,
Auxiliary rig side ground can smoothly be reached, reliability is high；
2nd, pass through to arrange limit spring, when shaking hands fixture block card main opposite drilling tool, limit spring meeting automatic spring simultaneously withstands
Shake hands pull bar, prevent opposite drilling tool from pull bar abjection of shaking hands；
3rd, pass through to arrange guide table and guided rings, make opposite drilling tool and be arranged concentrically with pull bar of shaking hands, further increase this
The work efficiency of invention.
Brief description
Fig. 1 is the structure chart of the present invention.
Fig. 2 is to shake hands the side view of drilling tool when opposite drilling tool has just enter into cartridge type of the present invention.
Fig. 3 is when opposite drilling tool is shaken hands the side view that drilling tool blocks by cartridge type of the present invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, present embodiments provide a kind of cartridge type shaking hands drilling tool, including outer shell barrel 1, it is provided with outer shell barrel 1
Multiple pull bars 3 of shaking hands, the present embodiment so that pull bar of shaking hands is 4 as a example illustrates, and described pull bar 3 of shaking hands is along along outer shell barrel 1
Circumferentially, one end of described pull bar 3 of shaking hands bends wall to the center position of outer shell barrel 1, and the bending place of described pull bar 3 of shaking hands leads to
Cross bearing pin 7 to be hinged with outer shell barrel inwall, wherein, each bending end in the pull bar 3 of shaking hands being arranged oppositely passes through spring 8 even
Connect, the other end of the pull bar 3 that makes to shake hands is be arranged in parallel with outer shell barrel inwall, and the pull bar 3 that makes to shake hands is in normally open.Shaking hands
The other end of pull bar 3 is provided with fixture block 4 of shaking hands, and described fixture block 4 of shaking hands passes through torsion spring 8 and bearing pin 11 is hinged with pull bar 3 of shaking hands,
In each shakes hands pull bar 3, correspondence is shaken hands, and fixture block setting is fluted, and in the presence of external force, card of shaking hands fast 4 is pushed into groove
Interior.The other end termination of described pull bar 3 of shaking hands is connected with outer shell barrel also by limit spring 10, and when shaking hands, pull bar 3 is in receipts
During contracting state, limit spring 10 can be opened automatic spring preventing railing 3 of shaking hands again.
The bending segment being located at pull bar 3 of shaking hands in outer shell barrel is correspondingly provided with for guiding the concentric guiding of drill bit and outer shell barrel
Platform 9, guide table 9 is installed in outer shell barrel 3 inwall, and described guide table is to be obliquely installed, angle of inclination and direction and pull bar 3 of shaking hands
Bending end is consistent.
