Description
Technical field
This utility model relates to a kind of mining industry downhole drilling apparatus, particularly relates to a kind of underground for probing and discharges water correcting drilling tool.
Background technology
When carrying out leting speeper boring in down-hole, need to use probing harness, and existing most of drilling tool, error is drilled little in the case of lithology is stable, but run into crushed zone, structural fracture band is time maybe lithology changes at this, easy off-design orientation during causing drilling operation, probing orientation is forbidden, easily cause and visit by mistake, the minimum position of hydrops can not be visited, particularly in the case of construction area has a large amount of hydrops, if design attitude can not accurately be visited, downhole production safety will be directly affected, even cause the generation of gushing water situation, simultaneously, running into the situation drill pipe bucklings such as sillar caves in causes drill bit can not pull out out, have a strong impact on work quality and efficiency.
Summary of the invention
This utility model is for above-mentioned deficiency of the prior art, it is therefore an objective to provide a kind of reliable and stable, can the underground for probing of correcting discharge water drilling tool.Guarantee in drilling process, even if running into the geological structure that crushed zone, structural fracture band etc. are complicated, it is possible to visit the minimum position of hydrops exactly by design orientation, angle, thoroughly release water damage to threaten, realize safety in production, drilling tool can be made simultaneously to pass in and out sillar more easily, improve work efficiency.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is:
A kind of underground for probing discharges water correcting drilling tool, including:
Drill bit；
Drilling rod；And
Drill body, its front end is connected with drill bit, and its rear end is connected with drilling rod；
It is characterized in that: described drilling rod, drill bit and drill body coaxial line, drill body is cased with at least one stiffening device, and stiffening device outer circumferential arranges at least one drill lip.
Above-mentioned stiffening device is enclosed within drill body.
Above-mentioned drill lip is embedded on stiffening device.
Above-mentioned stiffening device is reinforcing ring.
The a length of 0.5-5m of above-mentioned drill body.
Above-mentioned drill body is circular tube structure.
This utility model has the beneficial effect that
Compared with prior art, this utility model, by arranging drill body between drill bit and drilling rod, adds the length of whole probing harness, arranges reinforcing ring in the outside of drill body, drilling process can be effectively prevented the flexural deformation of drill body, making drilling tool not deviate by design orientation, the outside of reinforcing ring arranges drill lip, when boring, drill lip rotates with drill body, hole wall is formed " support ", it is ensured that the concentricity of boring, play correcting effect.
Accompanying drawing explanation
The following drawings is only intended in this utility model is made schematic description and interpretation, however it is not limited to scope of the present utility model.Wherein,
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view of this utility model A-A part in Fig. 1.
Detailed description of the invention
In order to technical characteristic of the present utility model, purpose, effect and embodiment are more clearly understood from, in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
A kind of underground for probing as shown in Figure 1 and Figure 2 discharges water correcting drilling tool, including drilling rod 1, drill bit 4 and drill body 3, this drill body 3 front end is connected with drill bit 4, and drill body 3 rear end is connected with drilling rod 1, drilling rod 1, drill bit 4 and drill body 3 coaxial line, the rear end of drill body 3 and middle part are all cased with reinforcing ring 2, reinforcing ring 2 outer circumferential is embedded with drill lip 5, and the quantity of drill lip 5 is generally 3-8, and the present embodiment is 8, when its quantity is multiple, generally it is uniformly arranged along reinforcing ring 2 circumference.This utility model specifically operates as follows, during boring, rig drives drilling rod 1 to rotate, drilling rod 1 drives drill bit 4 to drill by drill body 3, at the geological structure running into complexity, when crushed zone or lithology change, owing to being additionally arranged drill body 3 between drilling rod 1 and drill bit 4, add the length of whole probing harness, reinforcing ring 2 is set in the outside of drill body 3 simultaneously, drilling process can be effectively prevented the flexural deformation of drill body 3, the hole that drill body 3 gets out is exactly straight, drilling tool is made not deviate by design orientation, so drilling rod 1 can be advanced along the straight hole that drill body 3 gets out the most inwards when boring, can the most outwards extract again when being drilled；And drill lip 5 is set in the outside of reinforcing ring 2, when boring, drill lip 5 rotates with drill body 3, and hole wall is formed " support ", it is ensured that the concentricity of boring, plays correcting effect, and when extracting drilling tool, the rotation of drill lip 5 is also beneficial to extract drilling tool.So, this utility model, in drilling process, has preferable stability, reliability；When the geological structure crushed zone or lithology running into complexity changes, it is possible to guarantee to visit exactly by design orientation, angle the minimum position of hydrops during drilling operation, thoroughly solve water damage and threaten, it is achieved safety in production.
In such scheme, a length of 0.5-5m of drill body 3.
In such scheme, drill body 3 is circular tube structure.
In such scheme, drill body 3 can arrange several reinforcing ring 2 more.
The foregoing is only the schematic detailed description of the invention of this utility model, be not limited to scope of the present utility model.Any those skilled in the art, the equivalent variations made, revises and combines on the premise of without departing from design of the present utility model and principle, without departing from spirit of the present utility model, all should belong to the scope of this utility model protection.
