Description
Technical field
The utility model relates to spring examination bitubular ice core machine dimensions drill in ice core drills through, a kind of device in drilling tool duty in the borehole.
Background technology
Bitubular ice core machine dimensions drill is drilling through in ice core process, drilling tool motor is fixed on urceolus upper end, under motor power transmission, inner core turns clockwise at outer barrel, the cutter head cutting ice sheet is fixed on inner core lower end, inherently resistance is produced when ice face is cut ice sheet, this resistance is exactly reaction force, and its direction of rotation is counterclockwise.Drilling pipe inner core is under the impact of reaction force, and whole drilling tool (urceolus) will be rotated counterclockwise, and in order to not make urceolus rotate, spring now plays a role, and is tightly stuck in ice hole the reaction force overcome because bit cutting ice sheet produces.The anti-twisted system of spring is fixed on the motor case ambient envelope four direction of urceolus upper end.If spring stretches tight and not turn on the inwall of ice hole, urceolus would not rotate naturally.But the tension of this scale can promote drilling tool to capstan winch again and add to the difficulties, on ice wall, have certain resistance because spring jumps when each has bored rear lifting drilling tool, this resistance have impact on the rate of climb to a great extent.
Summary of the invention
In order to the low resistance of spring spring on ice wall that disappear, the purpose of this utility model is to provide a kind of spring to try the anti-twisted device of bitubular ice core machine dimensions drill
.it can open spring can make spring loosen minimizing and ice wall friction resistance again completely when promoting drilling tool, thus reaches the object of fast lifting drilling tool.
The purpose of this utility model is achieved in that
The anti-twisted device of a kind of spring formula bitubular ice core machine dimensions drill is by screw rod, nut, stage clip, the first locating sleeve, the second locating sleeve, upper end cover, and bottom end cover, spring, clip and spring rotating disk are formed.Upper end cover is provided with strain relief clamp, on screw rod around strain relief clamp, cover has stage clip, and on stage clip, cover has the first sleeve pipe, and stage clip end is screwed with nut, then screw rod is through the through hole on upper end cover, termination screw thread is fixed on bottom end cover, and screw rod puts the second sleeve again, clip on spring rotating disk, spring is connected with between upper end cover and clip, variable speed electric motors, particularly is connected with inner core by motor power output shaft with variable moderator, and inner core is placed in urceolus, and urceolus is connected with spring rotating disk.
Advantage of the present utility model:
1, the utility model can be pushed down spring force its ice wall that stretches tight to overcome anti-twisted power by being adjusted to stage clip, and rig urceolus is not turned.When promoting, drilling tool weight own exceedes the pressure of stage clip, will pull open stage clip during rising, ice wall spring being left stretch tight, thus reaches the object that non-resistance rises.
2, screw rod is fixed between upper end cover and bottom end cover, the sleeve pipe adopted therebetween can only on move certain distance, be subject to the restriction that stage clip pressure is subject to sleeve pipe simultaneously when ensureing that screw rod moves up.
3, drilling tool is when when drilling through ice core, each promotes after having bored, eliminates the resistance because spring and ice wall extrusion friction produce, accelerates hoisting velocity, improve the efficiency drilling through ice core.
accompanying drawing illustrates:
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the schematic perspective view of Fig. 1.
In figure: 1-strain relief clamp, 2-nut, 3-screw rod, the 4-the first locating sleeve, the 5-the second locating sleeve, 6-spring, 7-clip, 8-ice hole wall, 9-urceolus, 10-spring rotating disk, 11-gearbox, 12-variable speed electric motors, particularly, 13-motor power output shaft, 14-bottom end cover, 15-upper end cover, 16-stage clip, 17-cable input, 18-inner core.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further again:
As Figure 1-Figure 2, the anti-twisted device of a kind of spring formula bitubular ice core machine dimensions drill is that bottom end cover 14, spring 6, clip 7 and spring rotating disk 10 are formed by screw rod 3, nut 2, stage clip 16, first locating sleeve 4, second locating sleeve 5, upper end cover 15.Upper end cover 15 is provided with strain relief clamp 1, and being equipped with cover on four identical screw rods of bore, 3, four screw rods 3 around strain relief clamp 1 has stage clip 16, and stage clip 16 65 manganese carbon steel are made, diameter 2mm, pitch 4.5mm, the number of turns 12, length 54mm.Single stage clip compression 10mm-20mm, pressure is about 6-8 kilograms.On stage clip 16, cover has first sleeve pipe 4 of the long 30mm of Φ 20*2, and end is screwed with nut 2, and then screw rod 3 is through the through hole on upper end cover 15, and termination screw thread is fixed on
bottom end cover 14,screw rod 2 puts again
Φ 17*0.8second sleeve 5 of long 80 mm, spring rotating disk 10 there is clip 7, spring 16 is connected with between upper end cover 15 and clip 7, variable speed electric motors, particularly 12 and variable moderator 11 are placed in motor housing, be connected with inner core 18 by motor power output shaft 13, inner core 18 is placed in urceolus 9, and urceolus 9 is connected with spring rotating disk 10.
Nut 2 with
upper end cover 15 surfacebe highly 34mm.In implementation process, downward regulating nut 2, stage clip 16 be have compressed 20mm, now upper end cover 15
downward pressure is about 32 kilograms.Drilling toolafter entering ice hole,
be fixed onupper end cover 15
withbetween clip 7
'sspring 6 is naturally just softened.Variable speed electric motors, particularly motor 12 is switched on power by cable input 17 and starts to rotate, motor power power transmission shaft 13 exports to rig inner core 18, inner core 18 upper tool post turns clockwise and cuts ice sheet generation reaction force, this reaction force passes to gearbox 11 by power transmission shaft, its direction of rotation is counterclockwise, now spring 6 blocks ice hole wall 8 and reaches and overcome reaction force rig urceolus 9 is not turned under upper end cover 15 pressure, and inner core 18 is remained a constant speed the work of having crept into and having drilled through ice core.When preparing to promote drilling tool, under the effect of the steel cable in strain relief clamp 1, upper end cover 15 is moved up 3--4mm, the tension force of release stage clip 16, spring 6 natural relaxation strutted, the resistance that spring 6 props up ice hole wall 8 disappears, the speed that drilling tool rises just is accelerated, and reaches the object that non-resistance rises
.
