Description

A kind of sealing structure of core plugging notifying mechanism of rope core drilling
Technical field
A kind of core plugging notifying mechanism of rope core drilling is the utility model is related to, is taken more particularly, to a kind of rope that can realize horizontal drilling The sealing structure of core drilling tool.
Background technology
In recent years, there is the core plugging notifying mechanism of rope core drilling that client is required to carry out horizontal drilling.And original core plugging notifying mechanism of rope core drilling, For be all upright opening and low-angle hole, drilling tool inner tube assembly moves by own wt and is maintained at bottom hole.If desired It is modified to horizontal drilling tool, it is necessary to design a kind of mechanism, the inner tube assembly of drilling tool can be sent to bottom hole from aperture, and drilling During allow inner tube assembly to be maintained at bottom hole position.
Refer to shown in Fig. 1, Fig. 1 is the structural representation for the core plugging notifying mechanism of rope core drilling that can realize horizontal drilling in the prior art Figure, such a structure have installed bullet card holder connector 10, pumping valve block 11, adjust pad additional on the basis of common core plugging notifying mechanism of rope core drilling 12 and connector 13.During inner tube assembly is launched, the inner tube assembly of this set drilling tool is put into the drilling rod of aperture, drilling rod connection Tap, open slush pump.Due to pumping valve block 11 and drilling rod gap very little, it is more than certain MPa of situation in mud pump pressure Under, the water pressure pushing drilling tool pumped on valve block 11 travels forward in drilling rod, until inner tube assembly reaches bottom hole position.Drilling During, slush pump is always maintained at open mode, and the hydraulic pressure pumped on valve block 11 exists always, it is ensured that inner tube assembly is in hole Bottom position.
This structure solves to a certain extent is modified to horizontal lanyard core bit by common core plugging notifying mechanism of rope core drilling Problem, but in actual mechanical process or there are problems that:
1) in order to ensure to pump the hydraulic pressure on valve block, the gap pumped between valve block and drilling rod inwall will be as far as possible It is small.If gap is excessive, mud all goes out outflow from gap, and the hydraulic pressure pumped on valve block is not big enough, will be unable to promote inner tube assembly Travel forward;If gap is too small, pumping valve block can wear and accelerate with wall friction in drilling rod, as drilling rod inner wall size has error, Inner tube assembly can be stuck in drilling rod, can not be further along.
2) valve block is pumped in forward movement, is elastomeric material due to pumping valve block always with wall friction in drilling rod, Quickly, replacement frequency is higher for abrasion.
Utility model content
The purpose of this utility model is to provide a kind of sealing structure of core plugging notifying mechanism of rope core drilling, and it can realize horizontal brill Enter, there is the characteristics of making full use of hydraulic pressure and substantially reducing abrasion, to solve that the rope of horizontal drilling can be realized in the prior art Above mentioned problem existing for core bit.
To use following technical scheme up to this purpose, the utility model:
A kind of sealing structure of core plugging notifying mechanism of rope core drilling, it includes outer tube short circuit and the company being arranged in the outer tube short circuit Joint, piston rod and piston, one end connection bullet card room of the outer tube short circuit, other end connection outer tube, wherein, the piston rod One end be installed in the room top connection of bullet card, other end installation connector, the connector is installed in the room lower contact of bullet card, institute State piston to be installed on the piston rod, and the piston offers positioned on the one side of the bullet card room top connection One encloses groove, leads to the outside spreading of piston after water under high pressure in the groove.
Especially, one end of the outer tube short circuit is provided with external screw thread, and screw thread company is carried out by the external screw thread and outer tube Connect, and the other end of the outer tube short circuit is provided with internal thread, is threadedly coupled by the internal thread with bullet card room.
Especially, one end of the bullet card room top connection is provided with the first cylinder construction section, corresponding on the piston rod First step hole is offered, the first cylinder construction section is inserted in the first step hole.
Especially, one end of the connector is provided with second step hole, the end insertion described second of the piston rod In stepped hole, and the end of the connector is resisted against the side of the piston, and the other end of the connector is provided with second Cylinder construction section, corresponding to the 3rd stepped hole is offered in the bullet card room lower contact, the second cylinder construction section inserts institute State in the 3rd stepped hole.
The beneficial effects of the utility model are, compared with prior art the sealing structure of the core plugging notifying mechanism of rope core drilling have with Lower advantage:
1) during drilling tool inner tube assembly is sent into, current enter in the groove of piston, and the outer wall of piston is outwards risen Open and withstand drilling rod inwall, so as to thoroughly shut the gap of piston and drilling rod inwall, allow the utilization rate of current to reach maximization.
2) when inner tube assembly is sent into, piston is almost very close to each other with drilling rod inwall, but because rubber piston has bullet in itself Property structure, wearing can substantially reduce compared with traditional.
