Brief description
Above-mentioned be only technical solutions of the utility model general introduction, in order to better understand technology handss of the present utility model
Section, below in conjunction with accompanying drawing, the utility model is described in further detail with specific embodiment.
Fig. 1 is existing jackrod structure schematic diagram.
Fig. 2 is water saving jackrod structure schematic diagram of the present utility model.
Fig. 3 A, Fig. 3 B, Fig. 3 C be respectively in Fig. 2 A-A to, B-B direction and C-C to sectional view.
Specific embodiment
This utility model provides a kind of water saving drilling rod, good seal performance, can thoroughly prevent drilling rod boring continued access process
In drainage, reduce the water leakage situation of drilling rod and rig junction, substantially reduce drilling process rig water consumption, improve
The reliability of equipment, provides good construction environment for coal mine underground construction process, and especially macropore warp, bradawl is deep, in high precision
Hole drilling operation, substantially increases drilling construction quality.
Please refer to shown in Fig. 2 and Fig. 3 A, 3B, 3C, water saving drilling rod described in the utility model includes drilling rod body,
And it is arranged on the left end stifled 5 as female joint for the drilling rod body end and the right-hand member stifled 8 as male joint, left and right end is blocked up on 5,8
Connection screw thread consistent with common drilling rod, can be taper thread or rectangular thread, shown in Fig. 2 be rectangular thread.Described drilling rod
Body includes outer tube 7 and inner tube 6, forms toroidal cavity between described outer tube 7 and inner tube 6, and the two ends of described toroidal cavity are respectively
Block up 5,8 inner face seal by described left and right end；It is provided with water flowing chamber, described left and right end blocks opens respectively in the middle part of said inner tube
It is provided with the limbers connecting with described water flowing chamber, wherein, be provided with for preventing at the limbers opening of described left end stifled 5
State the check valve 4 of water flowing intracavity water backflow.
In said structure, due to being provided with inner tube 6, the water-holding quantity of the internal water flowing intracavity of drilling rod greatly reduces.For common
Drilling rod (Fig. 1), the water of its drilling rod body 2 inner chamber belongs to waste water in drilling rod continued access and drilling rod unloading process, and each drilling rod continues
Connect and all can be back in tunnel with drilling rod unloading process, and drilling is required for refilling every time, the water use efficiency pole of drilling rod
Low.And of the present utility model water saving drilling rod because the increase of inner tube 6 is so that the aperture in water flowing chamber is substantially reduced, thus creeping into
Journey rig water consumption substantially reduces.Meanwhile, by arranging check valve 4, holed using water saving drilling rod of the present utility model
During, when drilling rod needs continued access, because of the presence of check valve 4, come into the water of all drilling rods in completing to hole it is impossible to
Block up 5 endoporus by drilling rod left end to be back in tunnel, and creep into every time and do not need to refill, drilling rod unloading process drilling rod
Interior water-holding quantity also significantly reduces, and substantially increases the water use efficiency of drilling rod, has saved the water consumption of drilling construction it is ensured that good
Drilling machine construction environment.
During practical application, this utility model economize on water drilling rod length L according to drill stroke it needs to be determined that, bore with common
Bar determines that method is consistent.In water saving drilling rod, the Opening pressure of check valve 4, according to boring needs, sets according to drilling construction situation
Fixed, generally 0.2MPa～0.5MPa.Because drilling rod boring with aperture and bores deep difference, there are different water consumptions and hydraulic pressure
Demand, therefore, in this utility model water saving drilling rod, inner tube 6 internal diameter, right-hand member block up 8 limbers aperturesAccording to drilling depth and
Bore diameter needs to be customized, and 8 limbers apertures are blocked up with right-hand member in the water flowing intracavity footpath of inner tube 6Unanimously.Water saving drilling rod
Outer tube 7 external diameterConsistent with general drill pipe diameter, can be set to Equal-specification.Exemplarily,
WithBy the latus rectum of existing common drilling rod as a example drilling rod(boring the water flowing latus rectum of deep design according to more than 100m)
It is reduced to(set upInner tube 6), can meet drilling rod 0-30m bore depth water need
Ask, saved 70%-80% water consumption again.Other diametersDifferent size water saving drilling rod water saving principle is identical with this, is also
By controlling the limbers latus rectum of inner tube 6 internal diameter and right-hand member stifled 8Realize the purpose of water saving.
Please continue to refer to shown in Fig. 2, described left and right end is blocked up to be additionally provided with 5,8 and is worked in coordination when joining end to end for drilling rod
One group sealing interface.As specific embodiment, as shown in Figure 2, it is concave structure that described left end blocks up 5, and right-hand member blocks up 8 and is
Convex shape, described left end blocks up the convex surface E of 5 peripheries, left end blocks up the concave surface F at 5 middle parts, right-hand member blocks up the concave surface G of 8 peripheries, right-hand member blocks up 8
The convex surface H face at middle part can be made into two groups of sealing interfaces, and drilling rod joins end to end when carrying out drilling construction, can be by E face and G face
Cooperation is sealed, or is sealed with the cooperation of H face by F face, and every kind of water saving drilling rod may be selected in two groups of sealing interfaces
One group as sealing surface.No matter sealing surface is organized using which, all can effectively alleviate the water leakage situation of drilling rod and drilling rod junctions.
Described left end is blocked up 5 and is additionally operable to be tightly connected with rig output shaft, and please refer to shown in Fig. 3 A, described left end blocks up 5
Outboard end there is cubic profile.This construction profile is easy to drilling rod and is quickly connected with rig, and left end blocks up the 5 of portion four directions profile
End with rig output shaft cooperation, for transmitting moment, make rig output torque be no longer necessary to oild chuck clamping drilling rod carry out defeated
Go out, be substantially reduced rig and bore case overall dimensions.During use, described left end blocks up the bore of 5 outboard endOpening and outside
End face E face is coordinated with rig output shaft, forms mechanical seal structure, can effectively reduce the leak feelings of drilling rod and rig junction
Condition.
In underground coal mine macropore warp, bradawl depth, high accurate hole drilling construction process, this utility model water saving drilling rod passes through upper
State the sealing water-saving structure of setting, in the drilling depth of 0-30m, many drilling rod combinations are had an effect, and can thoroughly prevent drilling rod boring
Drainage during continued access, reduces the water leakage situation of drilling rod and rig junction, can reduce drilling process rig water consumption
70%-80%.Therefore, water saving drilling rod of the present utility model provides good construction ring to coal mine down-hole drilling work progress
Border, improves the reliability of equipment, provides guarantee to the raising of drilling construction quality.
The above, be only preferred embodiment of the present utility model, not this utility model is made any formal
