Description
Technical field
The present invention relates to a kind of magnetic fishing tool, more particularly to a kind of efficient magnetic fishing tool for the probing of ice core.
Background technology
Currently, in during the polar drilling, low temperature can have a strong impact on the fragility and ductility of conventional engineering material, mostly
Number steel can become brittle at subzero 10 degrees Celsius.Even bored using the underground of low-temperature steel, tool steel or stainless steel making
In spy instrument, some parts (such as cutting tooth, screw, nut and rolling bearing) of some boring tools are finally because fatigue is ground
Damage or production quality be not up to standard and destroy so as to dropping to bottom hole.In addition, (such as screwdriver, spanner and others are small for small instrument
Parts etc.) bottom hole may also be dropped to., it is necessary to remove in time after foreign body is fallen into hole, otherwise drilling tool can be caused rapidly to grind
Damage, bit freezing, probing work is caused not to be smoothed out.At present, the mode extracted applied to junk under ice hole mainly has trash ice to take
Bits formula and magnetic force adsorption type.The former is to capture the chip containing junk by leakproof cylinder after ice core at junk is smashed to pieces, but smashs work to pieces
Tool diameter is confined to ice bore dia, can not obtain ice core card and have no progeny junk in annular gap, and the effect of smashing to pieces can destroy the depth
Layer is spent, loses ice core；The latter uses suspended magnet adsorption hole bottom junk, but magnet can not adsorb ice core-interporal lacuna higher depth and fall
Thing.Moreover, the two salvaging efficiency is relatively low, junk in single success drawing holes can not be ensured.
The content of the invention
The invention aims to solve in ice core drilling process fisher used exist in use it is all
More problems and provide it is a kind of for ice core probing efficient magnetic fishing tool.
Provided by the present invention for ice core probing efficient magnetic fishing tool include sleeve pipe, movable axis, the first magnetic patch and
Several second magnetic patch, wherein movable axis are plugged in the inner chamber of sleeve pipe, and the top of sleeve pipe offers chute, is provided with and slides in chute
Bar, the top of movable axis are located on slide bar, and movable axis can be slided up and down in the inner chamber of sleeve pipe, what movable axis slided
Stroke is corresponding to the height of chute, and the first magnetic patch is fixed on the bottom of movable axis, and number is inlaid with the circumferential interval of sleeve bottom
Individual second magnetic patch.
The top of sleeve pipe is connected with joint, and the bottom of sleeve pipe offers ice machine bin.
The bottom of movable axis is arranged with spring.
The side of each second magnetic patch is equipped with baffle plate, and baffle plate is broken when can prevent the second magnetic patch from rotating.
The operation principle of the present invention：
When the first magnetic patch of movable axis bottom, which touches, does not block disconnected ice core upper surface, sleeve pipe continues to transfer, now movable
The spring contraction of axle bottom, movable axis stop motion, sleeve pipe continue to decline, and due to the presence that ice is considered to be worth doing at annular gap, can hinder
The decentralization of sleeve pipe, now rotatable fisher cause ice bits enter in the ice machine bin of casing part, be embedded in sleeve pipe so as to allow
Several second magnetic patch of bottom preferably contact with the small junk of bottom hole, until fisher sleeve bottom reaches bottom hole annular gap
Place, now fisher can be salvaged to be located at simultaneously does not block disconnected ice core top and hole wall and the ferromagnetism junk in ice core gap；Rotate
Fisher, the second magnetic patch is set fully to be contacted with bottom hole, the baffle plate for being located at the second magnetic patch side now can effectively prevent second
Stress when magnetic patch rotates with fisher and be broken.When lifting fisher, the first magnetic patch and movable axis are under gravity
Free-falling, due to ice bits presence or other reasonses may result in slide bar and movable axis is blocked and can not normally fallen, now
The spring of movable axis bottom just can drive movable axis to return to original position, carry to earth's surface, be easy to remove and salvage
Ferromagnetic part, so as to realize salvage hole in the ferromagnetic small junk of class.
Beneficial effects of the present invention：
Fisher provided by the invention can in hole the ferromagnetism junk of optional position salvage, and salvage effect
Rate is high, and service life length, simple in construction, performance safety is reliable；And manufacture, be easy to use, being fully compatible among polar drilling
Ferromagnetic class small articles are salvaged.

Embodiment
Refer to shown in Fig. 1 and Fig. 2：
Include sleeve pipe 1, movable axis 2, the first magnetic patch 3 provided by the present invention for the efficient magnetic fishing tool of ice core probing
With several second magnetic patch 4, wherein movable axis 2 is plugged in the inner chamber of sleeve pipe 1, and the top of sleeve pipe 1 offers chute 5, in chute 5
Provided with slide bar 6, the top of movable axis 2 is located on slide bar 6, and movable axis 2 can be slided up and down in the inner chamber of sleeve pipe 1,
The stroke that movable axis 2 slides is corresponding to the height of chute 5, and the first magnetic patch 3 is fixed on the bottom of movable axis 2, in the bottom of sleeve pipe 1
Circumferential interval is inlaid with several second magnetic patch 4.
The top of sleeve pipe 1 is connected with joint 7, and the bottom of sleeve pipe 1 offers ice machine bin 8.
The bottom of movable axis 2 is arranged with spring 9.
The side of each second magnetic patch 4 is equipped with baffle plate 10, and baffle plate 10 can prevent from occurring to break when the second magnetic patch 4 from rotating
Split.
The operation principle of the present invention：
When the first magnetic patch 3 of the bottom of movable axis 2, which touches, does not block disconnected ice core upper surface, sleeve pipe 1 continues to transfer, and now lives
The spring 9 of the bottom of moving axis 2 shrinks, and the stop motion of movable axis 2, sleeve pipe 1 continues to decline, due at annular gap ice consider to be worth doing presence,
The decentralization of sleeve pipe 1 can be hindered, now rotatable fisher causes ice bits to enter in the ice machine bin 8 of the bottom of sleeve pipe 1, is inlayed so as to allow
Several second magnetic patch 4 embedded in the bottom of sleeve pipe 1 preferably contact with the small junk of bottom hole, until the bottom of fisher sleeve pipe 1 reaches
At bottom hole annular gap, now fisher can salvage simultaneously positioned at do not block above disconnected ice core and hole wall and ice core gap it is ferromagnetic
Property junk；Fisher is rotated, the second magnetic patch 4 is fully contacted with bottom hole, the energy of baffle plate 10 for being located at the side of the second magnetic patch 4 now
It is enough effectively to prevent stress when the second magnetic patch 4 rotates with fisher and be broken.When lifting fisher, the first magnetic patch 3 and work
The free-falling under gravity of moving axis 2, due to ice bits presence or other reasonses may result in slide bar 6 and movable axis 2 blocks
Firmly can not normally it fall, being now located at the spring 9 of the bottom of movable axis 2 just can drive movable axis 2 to return to original position, carry
To earth's surface, it is easy to remove the ferromagnetic part salvaged, the ferromagnetic small junk of class in hole is salvaged so as to realize.
