Abstract

A simple coal injector comprises a connection shaft and is characterized in that the connection shaft is connected with a middle shaft, a water inlet hole is formed in the middle shaft, one end of the middle shaft is provided with a threaded column, the threaded column is provided with a threaded column head, the middle shaft is sequentially sleeved with a shaft sleeve, an inner thread fixing ring and a connection variant head, the middle shaft is provided with a water inlet connector, two sealing rings are arranged in the middle shaft, the inner circle of the inner thread fixing ring is provided with threads corresponding to the threaded column, and the connection variant head is internally provided with threads corresponding to the threaded column head. The simple coal injection can be repeatedly used, the material cost can be lowered, the material expenses are saved, the economic benefits are remarkable, and under the existing condition that coal mine enterprises are depressed, the simple coal injector is a way to facilitate production development.

Description

Simple type pumping water into coal device
Technical field
The present invention relates to a kind of injector, particularly relate to the simple type pumping water into coal device of release solution danger technology in a kind of mining speciality Controlling of Coal Outburst.
Background technology
Drilling in construction, the pumping water into coal device used is bearing and hermetically-sealed construction.After use procedure, at other mineral matters such as the gases such as oxygen, carbon monoxide, carbon dioxide and water, broken coal bits, landwaste, oxide etch is carried out to the bearing of steel casting, soon bearing just there will be corrosion phenomena, have impact on the normal use of injector, and decrease injector application life, because common injector is expensive, thus the waste causing material resources strengthens, and Master Cost aggravates.Particularly at my company's high tension coal mining, getting working face constantly increases, and mining depth constantly increases simultaneously, and when bump threatens more and more serious, pumping water into coal work gets more and more, and the usage quantity of injector is also increasing.
Summary of the invention
The object of this invention is to provide one can reuse, will material expenditures be reduced, save the simple type pumping water into coal device of Master Cost.
For achieving the above object, the technical solution used in the present invention is:
A kind of simple type pumping water into coal device, comprise connecting axle, it is characterized in that: connecting axle is connected with axis, axis is provided with inlet opening, and axis one end is threaded post, and threaded column is with there being screw thread column cap, and axis overlaps successively has axle sleeve, internal thread retainer ring to become head with being connected; Axis arranges water supply connector, and axis inside is provided with two sealing rings; Internal thread retainer ring inner ring is provided with the screw thread corresponding with threaded column; Connect to become in head and be provided with and the screw thread corresponding to screw thread column cap.
Design simple type injector, can reuse, will reduce material expenditures, save Master Cost, remarkable in economical benefits, in the stagnant situation of current coal mining enterprise, is a kind of approach being conducive to production development.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is sectional view of the present invention.
Fig. 3 is assembling drawing of the present invention.
In accompanying drawing: 1, connecting axle; 2, axis; 3, inlet opening; 4, threaded column; 5, screw thread column cap; 6, sealing ring; 7, axle sleeve, 8, internal thread retainer ring; 9 connect change head; 10, water supply connector.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The present invention as shown in Figure 1, Figure 2 and Figure 3,
A kind of simple type pumping water into coal device, comprise connecting axle 1, connecting axle 1 is connected with axis 2, axis 2 is provided with inlet opening 3, axis 2 one end is threaded post 4, and threaded column 4 is with there being screw thread column cap 5, and axis 2 overlaps successively has axle sleeve 7, internal thread retainer ring 8 to become 9 with being connected; Axis 2 arranges water supply connector 10, and axis 2 inside is provided with two sealing rings 6; Internal thread retainer ring 8 inner ring is provided with the screw thread corresponding with threaded column 4; Connect to become in 9 and be provided with and the screw thread corresponding to screw thread column cap 5.
Embodiment
By decomposing common injector, its internal structure is improved, remove the metal bearing that corrosion easily occurs, add the sealing ring 6 that two rubber products manufacture, again the structure of injector is adjusted, devise the ring structure similar with its size according to the size of metal bearing size, as long as change two sealing rings 6 when repairing like this, because sealing ring 6 is rubbers, not perishable, the time of depositing can be extended.Such simple type injector is reusable, by changing connector, can be connected with multiple drilling rod.
