Description
Technical field
The utility model is related to anti-water burst device, and in particular to a kind of anti-water burst device of tunnel core plugging notifying mechanism of rope core drilling.
Background technology
Tunnel core plugging notifying mechanism of rope core drilling is mainly used in tunnel geological prospecting.Wire line coring technology is applied to tunnel probing, can
To improve drilling efficiency, core recovery percentage is improved.And tunnel probing is generally lateral aperture or uphole construction, run into work progress
During water flush region, drilling tool assembly can not sealing in time, harmfulness will be very big.
Utility model content
Technical problem to be solved in the utility model is, in order to overcome the deficiency of prior art, there is provided a kind of structure letter
Single, reasonable in design, in time, the anti-water burst that can effectively protect drilling tool and improve the tunnel core plugging notifying mechanism of rope core drilling of drilling efficiency is filled sealing
Put.
The utility model solves the technical scheme that its technical problem used：A kind of the anti-of tunnel core plugging notifying mechanism of rope core drilling is gushed
Water installations, including joint, seat ring, check valve overcoat, one-way valve spring, lower axle, outer tube, O-ring and steel ball, the seat ring are connecing
Inside the rear end of head, the joint is connected with outer tube, and the check valve overcoat is located at joint and outer tube, and check valve overcoat
Outer step be located at seat ring front end, the O-ring be located at check valve overcoat outer step bottom groove in, the O-ring it is cylindrical
Contacted with seat ring inner circle, the lower axle is fixed on check valve jacket internal, the one-way valve spring lower end is fixed on lower axle upper end,
The one-way valve spring upper end is contacted with steel ball, and steel ball is suppressed in check valve overcoat endoporus lower end.
Further, the joint is connected with external pipe thread.
Further, the lower axle is fixed on check valve jacket internal by elastic cylindrical pin.
Further, the O-ring is made up of quality of rubber materials.
Research practice shows, be increased on the basis of common tunnel core plugging notifying mechanism of rope core drilling by check valve overcoat and rubber material
The anti-water burst device of the compositions such as the O-ring pad of matter, during normal construction, flushing liquor from drilling rod and assembly annular gap toward under drilling tool
Portion is flowed, and O-ring seals passage of irrigation fluid with seat ring, and flushing liquor changes its course and flowed toward bottom hole from check valve overcoat endoporus, when
When flushing liquor pressure is more than the elastic force of one-way valve spring, steel ball is moved downward, and passage is opened, normal drilling, is run into construction and gushed
Behind water location, steel ball closed check valve overcoat endoporus under one-way valve spring pressure, O-ring seals drilling rod and assembly with seat ring
Between annular gap, water burst is closed in drilling tool bottom, will not gush out to aperture, it is ensured that construction safety.
The utility model simple structure, reasonable in design, sealing in time, can effectively protect drilling tool and improve drilling efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
Reference picture 1, the present embodiment includes joint 1, seat ring 2, check valve overcoat 3, one-way valve spring 4, lower axle 5, outer tube 6, O

Inside joint 1 and outer tube 6, and the outer step of check valve overcoat 3 is located at the front end of seat ring 2, and the O-ring 7 is located at outside check valve
Cover in the groove of 3 outer step bottoms, the inner circle of cylindrical and seat ring 2 of the O-ring 7 is contacted, and the lower axle 5 is fixed on outside check valve
Inside set 3, the lower end of the one-way valve spring 4 is fixed on the upper end of lower axle 5, and the upper end of the one-way valve spring 4 contacts with steel ball 8, and
Steel ball 8 is suppressed in the endoporus lower end of check valve overcoat 3.
In the present embodiment, the joint 1 is threadedly coupled with outer tube 6.
In the present embodiment, the lower axle 5 is fixed on inside check valve overcoat 3 by elastic cylindrical pin 9.
In the present embodiment, the O-ring 7 is made up of quality of rubber materials.
During normal construction, flushing liquor is from close with seat ring 2 toward drilling tool lower flow, O-ring 7 in drilling rod and assembly annular gap
Passage of irrigation fluid is sealed, flushing liquor changes its course and flowed toward bottom hole from the endoporus of check valve overcoat 3, when flushing liquor pressure is more than check valve
During the elastic force of spring 4, steel ball 8 is moved downward, and passage is opened, normal drilling, and after running into water flush region in construction, steel ball 8 is in list
To the endoporus of closed check valve overcoat 3 under the pressure of valve spring 4, between O-ring 7 and seat ring 2 seal the ring-type between drilling rod and assembly
Gap, water burst is closed in drilling tool bottom, will not gush out to aperture, it is ensured that construction safety.
