Abstract
The utility model discloses a kind of mining hydrogeological hole to drill blowout hookup, comprise: friction top, sealing ring, closed chamber, flange, bracing ring, flange is fixedly installed in cylindrical shape closed chamber lower end, bracing ring is fixedly installed at cylindrical shape closed chamber internal upper part, bracing ring top is placed with sealing ring, annular friction top is screwed in annular closed chamber upper end and is pushed down by sealing ring, and side, cylindrical shape closed chamber bottom is provided with discharge opening.Effectively can prevent from water burst from spraying aperture to hurt sb.'s feelings, ensure the safety of constructor, there is the features such as structure is simple, easy to install, blowout prevention is effective.
Description
Technical field
The utility model belongs to coal mine hydrogeology exploratory works and to drill equipment technology field.
Background technology
In order to find out Geological Structure in Coal Mine situation, water damage accident in coal production process of preventing and treating occurs, and needs to utilize rig to drill to rock stratum and carries out hydrogeologic prospecting.Current hydrogeologic prospecting rig hole knockout is: first make a call to a shallow bore hole at survey position place, fixed sleeving is fixed in shallow bore hole, sealing gate valve is fixedly connected with at fixed sleeving external end head, then the drilling rod of rig is penetrated into fixed sleeving inner bottom by sealing gate valve, implement to creep into punching to rock stratum, punch complete find out hydrological geological conditions after, extract drilling rod and close sealing gate valve, prevent and treat inner water burst and flow out impact and produce.In practice of construction, rig is when underground coal mine prospecting by drilling, when the water yield in the aquifer run into, hydraulic pressure are larger, just have a large amount of water or coal (rock) sprays from aperture, water spray damages along the personal safety of drilling rod to drilling operation personnel, drill site operating environment is worsened rapidly, affects normally carrying out of hydrogeologic prospecting work.
Summary of the invention
The purpose of this utility model is to provide a kind of mining hydrogeological hole of hurting sb.'s feelings of can effectively preventing from spraying water and drills blowout hookup.
To achieve these goals, the utility model comprises: friction top, sealing ring, closed chamber, flange, bracing ring, flange is fixedly installed in cylindrical shape closed chamber lower end, bracing ring is fixedly installed at cylindrical shape closed chamber internal upper part, bracing ring top is placed with sealing ring, annular friction top is screwed in annular closed chamber upper end and is pushed down by sealing ring, and side, cylindrical shape closed chamber bottom is provided with discharge opening.
So in use, bolt is utilized to be fixed on by the utility model on the flange of drilling orifice sealing gate valve, unclamp friction top, drill bit and drilling rod are extend in boring through friction top, sealing ring, closed chamber, flange, sealing gate valve, fixed sleeving successively, rotatably compressing lid makes close contact between sealing ring compression with drilling rod reach sealing effectiveness, connect a flexible pipe at discharge opening, then operate rig jointed rod and carry out exploration of drilling.When the water yield in the aquifer run into, hydraulic pressure have more greatly water spray phenomenon, due to the sealing function of sealing ring, boring water spray would not spray along drilling rod, but flow in gutter from sidewall discharge opening by flexible pipe, do not affect front constructor to continue to drill or rise to pull out drilling tool, effectively can prevent from water burst from spraying aperture to hurt sb.'s feelings, ensure the safety of constructor.There is the features such as structure is simple, easy to install, blowout prevention is effective.
accompanying drawing illustrates:
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is installation structural representation of the present utility model.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
detailed description of the invention:
As seen from Figure 1, Figure 2, the utility model comprises: friction top 1, sealing ring 2, closed chamber 3, flange 4, bracing ring 5.Flange 4 is fixedly installed in cylindrical shape closed chamber 3 lower end, should be consistent with the flange specification of sealing gate valve, be convenient to connect.Be fixedly installed bracing ring 5 at cylindrical shape closed chamber internal upper part, bracing ring 5 top is placed with sealing ring 2, and bracing ring plays barrier support effect to sealing ring, and annular friction top 1 is screwed in annular closed chamber upper end by screw thread and is pushed down by sealing ring 2.Side, cylindrical shape closed chamber bottom is provided with discharge opening 6, carries out draining for connecting hose.During actual use, first in exploration rock stratum 10, a shallow bore hole is made a call to, fixed sleeving 9 is fixed in shallow bore hole, sealing gate valve 11 is fixedly connected with at fixed sleeving 9 external end head, bolt 8 is utilized to be connected to by this device on sealing gate valve flange, unclamp friction top 1, drilling rod 7 is extend in boring through friction top 1, sealing ring 2, closed chamber 3, flange 4, sealing gate valve 11, fixed sleeving 9 successively, rotatably compress lid and make sealing ring compress close contact between drilling rod.Friction top, closed chamber, flange, bracing ring adopt corrosion resistant steel to make, to adapt to mine down-hole adverse circumstances; Sealing ring adopts wearable elastic quality of rubber materials processing and fabricating, to improve its application life.The large I of specification of the present utility model according to the hydrologic drill of construction, drilling tool is supporting makes series of products.
