Description
Technical field
The present invention relates to a kind of extracting tool, especially a kind of extracting tool of more common studs.
Background technology
On shield machine, cutterhead and main drive connection, main driving and anterior shield connection have all largely used studs, are tearing open
Stud is screwed into or back-outed using double nut interlock mode during dress.But since bolt arrangement is intensive, working space is limited,
When being screwed into, outboard nut can be directly twisted, but when dismounting is back-outed with box spanner, need to twist inner screw nut, can not directly use
Box spanner.
Usual studs twist it is more rigid in the case of, can not manually unload bolt, screw thread can be injured with box spanner,
Directly use double nut during box spanner that can not interlock, when interlocking inner screw nut is directly twisted with common wrench, building ring
Border causes spanner that can not use or put to good use not open.So just there is extracting tool proposed by the present invention.
Invention content
The object of the present invention is to provide a kind of extracting tools of studs, can be easily intensive in narrow space, arrangement
In the case of, dismantle studs.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of studs extracting tool, including interior six square set, studs, inner screw nut, outboard nut, outer sleeve and
Ratchet spanner, the studs exposed parts, interior six square set, inner screw nut and outboard nut are set in outer sleeve, inside
Nut and outboard nut, which screw, mutually to be locked on studs exposed parts, and outboard nut is located above inner screw nut；
Hexagonal hole is equipped among interior six square set, hexagonal hole coordinates with inner screw nut size gap, and the outer ring of interior six square set is set
There are two boss, two lug boss positions are opposite；
The top of outer sleeve is equipped with through-hole, and the external wall beneath of outer sleeve is set there are two being open, and the boss of interior six square set is inserted into
Torque is transmitted in cooperation in opening, and the driving end of ratchet spanner, which is inserted into through-hole, transmits torque.
Further, the through-hole is square hole, and driving end is square toes.
Further, interior six square sets and outer sleeve are process by steel alloy forging.
Further, the thickness of interior six square sets is less than the thickness of inner screw nut, again smaller than the thickness of outboard nut.
Further, the form-factor all same of the inner screw nut and outboard nut.
A kind of application method of the extracting tool of studs, includes the following steps：
Step 1, by studs inner screw nut, outboard nut adjustment alignment, interior six square set is sleeved on inner screw nut
On, patch bottom is placed；
Step 2 tightens outboard nut, makes inner screw nut and outboard nut mutually locked；
Outer sleeve is sleeved on studs by step 3, contains interior six square sets and boss is made to coordinate with opening of external wall one
It rises；
Step 4 selects the matched ratchet spanner of driving end, is connected by the square hole on outer sleeve, turn counterclockwise, by
It is interlocked in double nut, you can back-out this studs.
Relative to the prior art, studs extracting tool of the present invention has the advantage that：It is simple in structure, it can be
Bolt is densely arranged, studs is back-outed in the place of narrow space, and operating method is easy, one can be operated, and tool is simple,
It is at low cost.
