Description
Technical field
The utility model drags for powder device at the bottom of relating to a kind of deep hole hole.
Background technology
In mine curtain grouting engineering, hole generally darker, in order not stop up Effect of Fissure slip casting, in drilling process, must adopt again clear water to creep into, be unfavorable for arranging powder, simultaneously due to cement injection last mortar and repeatedly cleaning bottom of hole perfusion, can produce a large amount of tailings and the accumulation of cementing thing, on the other hand, due to needs making a trip back and forth repeatedly, for handled easily, so generally adopt general brill, general brill is often unfavorable for adopting the heart, residual rock core can be grated at the bottom of hole, can produce a large amount of landwaste, if tailings and talus deposit are more, be unfavorable for the circulation of clear water in cleaning bottom of hole or drilling depth process, can cause the burning of bits or underground drilling accident, how to guarantee at the bottom of hole clean, reduce bury drills burning of bits accident, safety in direct relation mortar depositing construction quality and construction hole.Existing technical scheme: the one, in basket junction, increase a sediment tube, after each upper boring, the tailings in sediment tube or chip are poured out, need to dismantle sediment tube not only bothers at every turn, and the tailings that at every turn can bring up or landwaste considerably less, effect is undesirable, and meanwhile, sediment tube is very large hidden danger, once have an accident, sediment tube is very difficult.The 2nd, with drilling tool, in the situation that not bothering to see me out water, carry out dry combustion method tailings and landwaste are got into basket by force, the method very easily causes the burning of bits and underground drilling accident, this needs operating personnel to possess good Specialized Quality and operant level, on the other hand, owing to still there being water in drilling rod, in trip-out process owing to existing head of liquid to form a downward thrust to landwaste and tailings, Kong Yueshen, in drilling rod, water column pressure is larger, thrust is also larger, basket inwall is also smooth, therefore be easy to landwaste and tailings to release from basket, this reason will directly cause dragging for powder failure.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, drags for powder device at the bottom of a kind of deep hole hole is provided, and can effectively drag for powder, convenient disassembly.
For solving above technical problem, the technical solution of the utility model is: a kind of deep hole drags for powder device at the bottom of hole, its difference is: it comprises male and female catcher, basket, pellet seat, pellet, the upper end of described basket is connected with described male and female by reducing joint and takes over, the lower end of basket is connected with described pellet seat, reducing joint, basket, in the cavity that pellet seat forms, be provided with mobilizable described pellet, the inner chamber of pellet seat is hourglass shape, the minimum place of hourglass shape inner chamber diameter is less than billiards diameter, on hourglass shape inner chamber, accent place diameter is greater than billiards diameter, the lower end of pellet seat is connected with the short tube of protection pellet seat.
By above technical scheme, described basket and reducing joint are by screwed connection, and basket and pellet seat are by screwed connection.
By above technical scheme, described pellet is steel ball.
Contrast prior art, beneficial features of the present utility model is:
1), drag for powder device at the bottom of this deep hole hole, be provided with pellet, because pellet proportion is greater than the proportion of tailings and landwaste, pellet can fall seal pellet seat prior to tailings and landwaste, tailings and landwaste is stayed in basket, thereby reached the object of dragging for powder;
2), drag for powder device at the bottom of this deep hole hole, basket and reducing joint are by screwed connection, and basket and pellet seat are by screwed connection, and convenient disassembly, is convenient to clean, and can be repeatedly used, and saves material.
Accompanying drawing explanation
Fig. 1 is the utility model example structure figure;
Wherein: 1-male and female catcher, 2-reducing joint, 3-basket, 4-pellet, 5-pellet seat, 6-short tube.
The specific embodiment
Below by the specific embodiment, by reference to the accompanying drawings the utility model is described in further detail.
Please refer to Fig. 1, the utility model embodiment deep hole drags for powder device at the bottom of hole, it comprises male and female catcher 1, basket 3, pellet seat 5, pellet 4, the upper end of described basket 3 is connected with described male and female catcher 1 by reducing joint 2, the lower end of basket 3 is connected with described pellet seat 5, reducing joint 2, basket 3, in the cavity that pellet seat 5 forms, be provided with mobilizable described pellet 4, the inner chamber of pellet seat 5 is hourglass shape, the minimum place of hourglass shape inner chamber diameter is less than pellet 4 diameters, on hourglass shape inner chamber, accent place diameter is greater than pellet 4 diameters, the lower end of pellet seat 5 is connected with the short tube 6 of protection pellet seat 5.
Concrete, described basket 3 is with reducing joint 2 by screwed connection, and basket 3 and pellet seat 5 are by screwed connection.
Concrete, described pellet 4 is steel ball.
Please refer to Fig. 1; in the utility model embodiment; reducing joint 2 is by screwed connection basket 3; the internal diameter of basket 3 is φ 89mm; basket 3 length are 3m left and right; the pellet seat 5 that the cavity shape of basket 3 lower ends by one of screwed connection is hourglass shape; the minimum place of pellet seat 5 inner chambers diameter is that on φ 30mm, inner chamber, accent place diameter is φ 50mm; can form sealing with φ 40mm pellet 4; pellet seat 5 bottoms are connected with the short tube 6 of protection pellet seat 5, and short tube 6 is the basket of the about 0.3m of a segment length.
In the utility model embodiment, the visual boring aperture of the diameter of basket is selected, with boring aperture Selecting Complete Set.
In the utility model embodiment, basket length can be looked the adjustment of boring concrete condition, and generally, between 1～6m, the length of the basket that bottom is short is capable of regulating also.
Please refer to Fig. 1, the using method of the utility model embodiment: take over 1 by male and female this device is connected with φ 50mm drilling rod, adopt rig elevator by under this device in hole, until lower motionless, then carry up and down drilling rod, make this device up and down in hole, in downward active procedure, it is upwards movable that landwaste and tailings can promote pellet 4, landwaste and tailings also enter basket 3, because pellet 4 proportions are greater than the proportion of tailings and landwaste, upwards in active procedure, pellet 4 can fall to sealing pellet seat 5 prior to tailings and landwaste, allow tailings and landwaste stay in basket 3, water can enter in drilling rod, and so forth, finally when overflowing from top rod, water pulls out of hole, now in basket 3, will fill tailings and landwaste, reach the object of dragging for powder, the short tube 6 that is positioned at bottom is mainly protection pellet seat 5, avoid by residual fragment, iron filings, rock dust blocks, after once dragging for powder, pellet seat 5 is dismantled, landwaste and tailings are poured out, after cleaning up, install and reuse, until the most at last in hole landwaste and tailings drag for totally.
The utility model handling ease, can be repeatedly used, and saves material; Simple to operate, to personnel specialty attainment, require lower; Once drag for powder more, service efficiency is high; Be applicable to various hole depths, there is no limitation.
Above content is the further description of the utility model being done in conjunction with concrete embodiment, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the those of ordinary skill of the technical field under the utility model, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
