Abstract
The utility model provides a rock cracking tool device, comprising a supporting axle, a rubber tube, a bowl-shaped pressing cap, a sealing screw cap, an increaser for a long liquid guiding tube, etc. The rock cracking tool is put into a drilled rock hole, the high pressure liquid is pumped by utilizing the sealing rubber tube, the rock cracking tool is expanded to crack the rock hole, and the rock is cracked. The utility model has the advantages of linear control, static silence, rapid crack (a few minutes), simple device structure, repeatable use and low production cost; the rock cracking tool obtains good effect on the single hole or the multi-hole cracking of the rock through the experiment.
Description
The utility model relates to a kind of technique device that is used for the rock spalling.
Ancient rock mining technology utilizes chisel, hammer and dragsaw to exploit, and work efficiency is slow, the person's of opening up fatigue.The production technique of modern rock cuts both ways, as then the rock crack time is grown, rock cleavage device and steel cable dragsaw be unsuitable for the high rock of mining rate again with expensive high, the soundless cracking agent of flame thrower cost of winning; Adopt explosive blasting bulk percentage of head rice low, and batholith damage to some extent.
For addressing this problem Soviet Union's nineteen eighty-three patent: 1028842A (19) SU(11) has proposed the rock rupture device.It is made up of pedestal, elasticity jar and the element that rises brokenly.Adopt hydraulic pressure to make the resilient sleeve interlayer (metal shell) that expands again, press to the rock aperture, make it break.Such structure, with the diameter petrosal foramen, under the condition with length, the diameter that must make fluid column in the resilient sleeve is less relatively and reduce overall expansion power.
The purpose of this utility model is that a kind of technique device that is used for the rock spalling will be provided.
The utility model be achieved in that (seeing accompanying drawing) it by bolster (7), rubber tube (9), bowl-shape gland (6,10), seal screw cap (13) and long catheter reducing joint formations such as (2).Bolster (7) is made by metal material, and its stage casing is a circular shaft, and there is screw thread at two ends, is the taper seat of symmetry between screw thread and the circular shaft, and tapering is best with 3 °-12 °.Fluted between taper seat and screw thread, both ends of the surface have aperture (a, a respectively
1) with taper seat on aperture (b, b
1) communicate, be the passage in the liquid turnover rubber tube (9).The rounded rubber tube (9) in outside is being overlapped on bolster (7) surface, its tube wall has shearing resistance bed course (8), to improve its intensity, the interior stage casing of rubber tube (9) is rounded, there is the short round platform of symmetry two outer ends, the two ends inwall has the circular cone inclined plane, and two ends embeds respectively in bolster (7) groove, and termination thickness is 1 to 4 times of stage casing tube wall.Bowl-shape gland (6,10) is being overlapped in outside, rubber tube (9) two ends, and the one end is that bowl-shape endoporus and the short round platform of rubber tube (9) outer end symmetry coincide, and there are a screwed hole and bolster (7) threaded engagement in the centre.The following of device is seal screw cap (13), has a flat screwed hole and bolster (a 7) screw thread to closely cooperate.Sealing annular gasket (12) is housed in case high pressure liquid leaks at the bottom of the screwed hole.Long catheter reducing joint (2) is arranged above the device, and there is through hole (C) at its center, and the surface has nut (1) that plastic handles (3) is fixing.There are screwed hole and bolster (7) threaded engagement in its lower end, makes through hole (C) and aperture (a
1) connect and to communicate, through hole (C) upper end has screwed hole to be connected with high-voltage power supply to communicate.
But the utility model spalling rock of different nature comprises granite, marble etc., but and linear directional control, static noiseless and break (in a few minutes) rapidly, apparatus structure is simple and reusable.Through test, rock single hole, porous spalling have been obtained good result, can be used as the direction of determining major principal stress in the rock stratum rapidly simultaneously.
Accompanying drawing: rock expander sectional drawing
Among the figure: the long catheter reducing joint of (1) nut (2) (3) plastic handles (4,12) sealing annular gasket (5,11) hold-down nut (6,10) bowl-shape glands (7) bolsters (8) shearing resistance bed courses (9) rubber tubes (13) seal screw cap (a, a
1) aperture (b, b
1) aperture (C) through hole
The utility model will be explained as follows with embodiment.
Referring to accompanying drawing, intercepting one section round steel, to be processed into the stage casing be circular shaft, and two ends are screw thread, and there are two cutting planes with the parallel symmetry of axle in the stage casing of screw thread, makes the usefulness of wrench insertion.Be taper seat between screw thread and circular shaft, tapering is best for 3 °-12 °.Fluted between taper seat and screw thread, its size and rubber tube (9) external end head thickness is corresponding, bores aperture (a, a at end face
1) and taper seat aperture (b, b
1) communicate.This is bolster (7).With two-end thickness be stage casing pipe thickness 1-4 doubly, the internal diameter tapering is identical with bolster (7) and with nylon make shearing resistance bed course (8), the rubber tube (9) of doing inwall is enclosed within bolster (7) surface, in the groove of its termination embedding bolster (7).Again with having bowl-shape endoporus, its size to screw in respectively on bolster (7) screw thread with the bowl-shape gland that is threaded the hole (6,10) that rubber tube (9) two ends external diameter matches, make it be pressed on rubber tube (9) upper and lower end, and by hold-down nut (5,11) that it is fastening.The lower end of device screws in flat screwed hole seal screw cap (13), at screwed hole bottom and bolster (7) end face, sealing annular gasket (12) is housed in case high pressure liquid is released.Device upper end screw-in appearance is with plastics handgrip (3), the internal diameter two ends are that screwed hole, centre have the long catheter reducing joint (2) of through hole (c) and high-voltage power supply to join.This moment through hole (C) two ends respectively with aperture (a
1) and high-voltage power supply communicate.Catch plastics handgrip (3), the rock expander is put into its length, the corresponding petrosal foramen of diameter, pump into high pressure liquid stream via through holes (C), aperture (a from long catheter reducing joint (2)
1) (b
1) arrive to reach between bolster (7) and the rubber tube (9) and (a) locate to flow at aperture (b).Owing to there is seal screw cap (13) fastening, liquid that can not leaks, and makes rubber tube (9) generation elastic expansion press to the petrosal foramen hole wall.As at 30 * 30 * 30cm
3New granite sample in, then increase to 280-390kg/m at pressure
2The time (about 1 minute), petrosal foramen breaks voluntarily.
