Description

A kind of mechanical retractable hydraulic giant based on turbine and worm transmission
Technical field
The present invention relates to a kind of flexible hydraulic giants suitable for hydraulic borehole mining, more particularly to a kind of to be passed based on turbine and worm Dynamic mechanical retractable hydraulic giant.
Background technology
BOREHOLE HYDROMNING is first to drill in target area, and it is deep that giant then is placed on target ore bed in drilling At degree, using the high energy fractured rock of high-velocity fluid carrying injected by pressure, last fragmented rock forms solid-liquid with drilling fluid Mixture is pumped to earth's surface by surface equipment, and the recovery method of separation and Extraction mineral is then carried out to ore pulp.Hydraulic borehole mining Technology has many advantages, such as that cost of winning is low, production efficiency is high, small to surrounding environment influence.Traditional its high pressure of hydraulic mining drilling tool (operating) water nozzle is fixed on drilling tool outer wall, and nozzle location is irremovable, during the radius of ore bed fracture area becomes larger, high pressure The resistance of drilling fluid and slag also increases therewith in the fracture area that water is subject to after spraying, and the energy for leading to high pressure water fractured rock is anxious It falls sharply low, significantly reduces the production efficiency of hydraulic mining.
To solve the above-mentioned problems, existing patent document " CN104018840A " discloses a kind of based on pawl locking machine The flexible hydraulic giant of structure, but the hydraulic giant can only could withdraw water when hydraulic giant is flared to maximum angle by release device unfreezing Rifle." CN104005767A " discloses a kind of automatically controlled flexible drilling tool for hydraulic borehole mining, but the drilling tool remote control skill Art is still not perfect, and stepper motor and retarder, controller working environment are severe, and sealed environment does not allow easy heat radiation, at position of stretching It works under ore pulp environment, seal request is high, fragile." CN203961980U ", which is disclosed, a kind of to be controlled based on spring chuck Flexible hydraulic giant, but the hydraulic giant, when working under conditions of having drilling fluid, clamping force is inadequate, and it is unreliable that hydraulic giant is fixed, and in water When rifle is not extended out to maximum angle, hydraulic giant can not be withdrawn, therefore next there is an urgent need for a kind of novel technical solution in the prior art Solve the problems, such as this.
Invention content
The present invention provides it is a kind of based on turbine and worm transmission mechanical retractable hydraulic giant, during hydraulic mining, Angle can be stretched out by required hydraulic giant, in earth's surface rotary worm, turbine, sliding panel be driven to move downward, so as to which hydraulic giant be driven to stretch out, When hydraulic giant, which reaches setting, stretches out angle, block worm screw, prevent its rotation, you can the stretching angle of fixed hydraulic giant, to rock into Row is broken.
The present invention includes high pressure water conveying system, hydraulic giant telescopic system and dreg removing system;
The high pressure water conveying system include high-pressure water pipe, bias take over, angle coupling, monitor rotary joint and Hydraulic giant, the top of high-pressure water pipe are connect with earth's surface high-pressure water, the bottom end of high-pressure water pipe by bias take over clamping screw with partially The heart takes over connection;Bias is taken over, angle coupling, monitor rotary joint and hydraulic giant are sequentially tightly connected, the mechanical retractable When hydraulic giant works, earth's surface high pressure water flows into bias by high-pressure water pipe and takes over, then is taken over by bias through angle coupling, monitor rotation Adapter flows into hydraulic giant, is sprayed from the nozzle at high speeds of hydraulic giant, realizes and rock is crushed.
The hydraulic giant telescopic system includes worm screw, sliding panel, worm gear, worm gear backplate, top cover, guide rod, guide rod Upper locking nut, guide rod lower locking nut, angle coupling, monitor rotary joint, hydraulic giant, mandril and the first bottom cover, Worm screw upper bearing (metal) is mounted in the bearing groove of top cover, and thrust bearing is mounted in the bearing groove of the first bottom cover under worm screw;Snail Bar bottom end is mounted under worm screw in thrust bearing, and upper end extends outwardly across worm screw upper bearing (metal);Sliding panel is welded on bias and takes over On, the perpendicular arrangement of side wall of sliding panel and protection pipe offers worm gear slot in sliding panel side;Worm gear is installed by worm-wheel shaft In worm gear slot and and worm engaging;Guide rod is two, is each passed through reserved on top cover, sliding panel and the first bottom cover Hole, and be fixed between top cover and the first bottom cover with guide rod upper locking nut and guide rod lower locking nut;Hydraulic giant and Mandril link slot is respectively welded on first bottom cover;Mandril by mandril link slot be mounted on hydraulic giant and the first bottom cover it Between, and fixed with pin;Worm gear backplate is located at worm gear both sides and is welded on sliding panel;When the mechanical retractable hydraulic giant works, Angle rotary worm is stretched out according to the hydraulic giant of design, worm gear is moved downward along guide rod, and sliding panel is driven to move downward, so as to logical The movement for crossing monitor rotary joint drives the connecting rod mechanism movement being made of mandril etc., realizes the flexible of hydraulic giant.
The dreg removing system includes top cover, scum pipe, scum pipe guide sleeve, the first bottom cover, the second bottom cover, bottom End cap attaching nut and bottom cover connection bolt, the top of protection pipe are connect with top cover, the bottom end of protection pipe and the first bottom End cap connects, and the first bottom cover connects bolt by bottom cover and connect with the second bottom cover;Scum pipe guide sleeve sequentially passes through One bottom cover and the second bottom cover, and be threadedly attached on the first bottom cover;Scum pipe lower end and scum pipe guide sleeve spiral shell Line connects, and scum pipe upper end passes through the through-hole on top cover to extend outwardly.During hydraulic mining, broken landwaste by Drilling fluid is carried returns to earth's surface through scum pipe.
The course of work of the present invention:
First, hydraulic giant is stretched out, fixes and is withdrawn:
After the drilling needed for hydraulic mining is completed, which is transferred to bottom hole, then rotary worm, Worm gear rotation is driven, so as to drive sliding panel slide downward, under the drive of link mechanism, the protruding certain angle of hydraulic giant, After reaching set angle, control worm screw stop operating, it is possible to realize hydraulic giant stretch out angle fixation, when need withdraw hydraulic giant When, only it need to rotate backward worm screw.
Two hydraulic giant rotating-spray detritus:
After stretching angle in hydraulic giant reaches requirement and fixes, rotation speed of the hydraulic giant along drilling axis is adjusted by drilling machine Degree, while high pressure water is taken over by high-pressure water pipe, bias, angle coupling, monitor rotary joint flow into hydraulic giant, from hydraulic giant Nozzle at high speeds sprays, fractured rock.
Beneficial effects of the present invention:
The present invention can stretch out angle, rotary worm, when hydraulic giant reaches setting during hydraulic mining by required hydraulic giant When stretching out angle, worm screw is prevented to rotate, you can the stretching angle of fixed hydraulic giant crushes rock.Hydraulic giant of the present invention stretches out Angular adjustment is free, and stretches out withdrawal conveniently, can avoid submerged jets according to the distance of design control hydraulic giant nozzle and ore bed The problem of high pressure water energy is caused drastically to weaken so as to achieve the purpose that improve the capacity usage ratio of high-pressure water jet, finally carries High production efficiency.
