Description
Technical field
The invention belongs to drilling machinery field, it is related to freezing pipe device under a kind of oblique freezing hole external clamping.
Background technology
Currently, China western part coal mine New Built Mine, mostly uses inclined shaft, slope development becomes trend；Such as the Inner Mongol built up
Horse Thailand moat mine main shaft, examine the plain mine main shaft in Kazakhstan etc..When building inclines since complex formation need to use construction freezing method in succession
Sinking shaft.Construction freezing method sinking shaft be around the coal mine inclined shaft pit shaft excavated in advance, drill out with tens of pit shaft coaxial line it is uniformly distributed
Freezing hole, then tripping in freezing pipe in hole by artificial cooling technology, makes the water freezing in stratum, will loose aqueous ground
Become frozen soil, increase its strength and stability, completely cut off underground water, under the protection of frost wall, carries out the pick of inclined shaft underground engineering and build
Operation.
For inclined shaft freezing, theoretically there is different schemes, when all tiltedly freezing hole, second is that all straight freezing hole, three are
It top and two helps with straight hole bottom inclined hole, four to be that top inclined hole two is helped to use straight hole.There is data to show, all oblique freezing hole side
Drilling for case and is freezed chilling requirement and is most saved quantities, and the excavation amount of frozen soil is minimum, and cost is minimum；But due to the brill of inclined hole
Hole technology and matched process technology are not broken through, so, currently, the inclines in China western part edge always in construction freezing method
With all straight freezing hole schemes.
Currently, being directed to oblique freezing hole, device and the process for providing a set of safe lower freezing pipe are very urgent.
Invention content
Technical problem solved by the invention be to provide it is a kind of be used for oblique freezing hole, the device of freezing pipe, real under external clamping
Existing safe and efficient lower freezing pipe.
In order to solve the above-mentioned technical problem, the technical solution used in the present invention is：Under a kind of oblique freezing hole external clamping
Freeze pipe device, including three parts, connection, torsion pass, sealing function play in first part, have central tube, torsion seat, Y shape sealing to lead
To set；Second part plays outer clip freezing pipe, there is slips, tapered sleeve, spring, steel ball, convergence set, key pin, bearing seat；Third portion
It is the oil cylinder for driving slips clamping to divide.Central tube upper end internal thread is connected with the main shaft of drilling machine, and lower end and torsion seat screw thread connect
It connects, guide sleeve and torsion seat are threadedly coupled, and Y shape is sealed between torsion seat and guide sleeve；There is a pair of of circular cone in central tube outer circle
Roller bearing, bearing outer ring and cylinder tube cooperation, central tube pass through among piston rod；Piston rod and bearing seat threaded upper ends
Connection；Suspend in midair steel ball and convergence set for bearing seat lower end, and convergence set lower end is connected with tapered sleeve, and tapered sleeve encloses card by inner conical surface
Watt, spring is mounted among slips and torsion seat.
There is steel ball between the bearing seat and convergence set.
Key pin is installed in the middle part of the convergence set.
The slips is three-clove style structure, and inner surface is the conical surface.
Piston and piston rod in the slips clamping cylinder are one.
Due to the adoption of the above technical scheme, the present apparatus is connected with slant rig main shaft, may be implemented by hydraulic system
Outer clamping freezing pipe, y-type seal ring seal freezing pipe, circulating fluid while lower freezing pipe, while drilling machine master may be implemented
Axis rotation, which drives, freezes tubing string rotation, and the lower freezing pipe of safety is realized from technique.

In figure：1. 5. cylinder tube of bearing, 6. anti-bull stick, 7. piston rod of 2. upper press cover of central tube, 3. round nut, 4. circular cone rolling
8. 14. tapered sleeve of convergence set 9. steel ball, 10. bearing seat, 11. key pin, 12. torsion seat, 13. spring, 15. slips 16.Y shapes sealing 17. is oriented to
Cover 18. freezing pipes
Specific implementation mode
It is described further below in conjunction with the accompanying drawings with specific embodiment to freezing pipe device under oblique freezing hole external clamping：
Such as attached drawing 1, central tube 2, upper press cover 3, round nut 4, the sub- bearing 5 of circular cone rolling, cylinder tube 6, anti-bull stick 7, live
Stopper rod 8, convergence set 9, steel ball 10, bearing seat 11, key pin 12, torsion seat 13, spring 14, tapered sleeve 15, slips 16, Y shape sealing 17,
Guide sleeve 18, freezing pipe
First, the present apparatus is installed on the main shaft of slant rig, the crane on drilling machine slings freezing pipe and tows to master
It in guide rail line, is clamped by clamper righting, the feeding system operation of drilling machine drives power head Forward, slowly by the guiding of the present apparatus
Set 17 and Y shape sealing 16 are inserted into the endoporus of freezing pipe 18.There is gap between the internal diameter and freezing pipe 18 of slips 15, starts hydraulic pressure
System, it is presetting to set system pressure, reversal valve is opened, oil cylinder cavity of resorption enters pressure oil, and the movement of piston rod 7 moves up, bearing seat 10
It is driven and moves up, while pulling convergence set 8, tapered sleeve 14 moves up；Tapered sleeve 14 is wrapped in slips 15, presses spring 13, directly
It is pressed onto position to spring 13, slips 15 and 18 gap of freezing pipe are eliminated, and continue the outer outer circle for clipping freezing pipe 18, until hydraulic pressure
System reaches the pressure set up.The freezing pipe butt welding of 18 front end of freezing pipe and tripping in, after welding, single freezing pipe is just
Freeze that tubing string is integral with entire, starts the mud circulating system of drilling machine, drilling machine fore-clamp holder is unclamped, the operation of drilling machine feeding system
Driving power head moves forward at a slow speed together, pushes and entirely freezes column at a slow speed in the oblique freezing hole of tripping in, in the process, dynamic head main spindle rotation
Central tube 1 is driven to rotate, central tube 1 drives torsion seat 12 to rotate, and torsion seat 12 drives convergence set 8 to rotate by key pin 11, and
The entire tubing string that freezes being clamped is driven to rotate.Entire tubing string, mud are clamped by fore-clamp holder after entirely freezing base for post this tripping in
The circulatory system is starched to stop.Hydraulic system reversal valve commutates, cylinder upper cavity oil oil inlet, pushes 7 downlink of piston rod, drives under bearing seat 10
Row, 8 downlink of convergence set, 14 downlink of tapered sleeve, 13 release force of spring pushes 15 downlink of slips, outside the no longer outer clip freezing pipe 18 of slips 15
Circle and freezing pipe 18 disengage gap, and feeding system operation moves after driving power head, and the present apparatus also goes out from freezing pipe with power
It is moved after head, into next cycle.
