Abstract
The invention relates to a strong sealing device of a hydraulic chuck for a gas pumping rig. The strong sealing device comprises a body, a cylinder, an external interface and an inner cylinder, wherein the body, the cylinder and the external interface are coupled sequentially; and one end of the inner cylinder is arranged in the body and coupled with a rack wheel, while the other end of the inner cylinder extends out of the external interface and is coupled with the chuck. The strong sealing device is technically characterized in that TB3 Che seals, wear resisting rings and glands are arranged at both ends of the cylinder; the TB3 Che seals are hermetically packaged between the cylinder and the inner cylinder through the glands; the outer circular walls of the TB3 Che seals are compactly attached to the inner wall of the cylinder body; the inner circular walls of the TB3 Che seals are attached to the outer wall of the inner cylinder through the wear resisting rings in a sealing mode; and the TB3 Che seals are compressed at both ends of the cylinder through the glands. The oil distributing and sleeving sealing device has the advantages of high-pressure resistance, wear resistance, and seal and no leakage, and wear of contact face can be automatically compensated.
Description
Technical field
The present invention relates to the coal mine machinery technical field, is the strong sealing that a kind of gas exhaust rig hydraulic chuck is joined oil jacket specifically.
Background technique
At present, the coal in China exploitation rate increases very fast, and along with the increase gradually of mining depth, coal mine gas danger outstanding and blast is also increasing, and the outstanding and explosive accident of gas often takes place.Early stage adopt big ventilation directly gas extraction in atmosphere, pollutant atmosphere does not meet the energy-saving and emission-reduction requirement.Present gas exhaust rig both domestic and external adopts hydraulic type chuck clamping drilling rod to bore the hole, colliery and bore the drawing-off gas hole, and by the hydraulic type chuck is big to the boring chucking power, clamping is firm, difficult drop-off, the long distance boring that is fit to the hole, colliery is used.Seal element in the gas exhaust rig is joined oil jacket can provide high pressure oil for the hydraulic type chuck of rotation at a high speed, make chuck have ability from axial force to drilling rod that transmit moment of torsion and, common contact of joining oil jacket is sealed in when rotating at a high speed easy to wear, causes high pressure oil to reveal, normal, the safe handling of influence
Summary of the invention
Join oil at available technology adopting gas exhaust rig and will seal deficiency easy to wear, seepage, the invention provides a kind of compact structure, can rotate simultaneously to the rig fuel feeding at a high speed, good seal performance uses safe gas exhaust rig hydraulic chuck to join the strong seal arrangement of oil jacket.
The technical solution used in the present invention is; A kind of strong seal arrangement of gas exhaust rig hydraulic chuck, comprise body, cylinder body, external tapping and inner core, body, cylinder body connect in turn with external tapping, described inner core one end put with body in connect with gearwheel, the other end stretches out external tapping and connects chuck, its technical characterstic is that described cylinder body two ends are equipped with TB3 Che Shi sealing, wear-resisting circle and gland, TB3 Che Shi sealing press-fits between cylinder body and inner core through gland seal, TB3 Che Shi sealing cylindrical wall sealing applying inboard wall of cylinder block, TB3 Che Shi sealing inner round wall is through wear-resisting circle sealing applying inner tank theca.
Described wear-resisting circle press-fits between cylinder body and inner core through gland seal, or the sealing of wear-resisting circle is arranged between gland and the inner core.
Advantage of the present invention is: the cylinder body two ends are sealed by gland pressing TB3 Che Shi, TB3 Che Shi sealing is made up of thin lips and teeth shape slip ring+O type circle, when being used for high speed rotary seal position, the slip ring crown is bordering on the line contact with contacting of surface of revolution, can significantly reduce the frictional heat that rotation at a high speed produces; The thin lip rigidity of slip ring is little, and O type circle is tightened in slip surface the thin lip of slip ring, and the slip surface oil film is very thin, is generally 0.001-0.0025, a lubricate, and unlikely scraped into to drip cause leakage; The elastic force of O type circle is compensated the line contact sealing surface wear automatically.The oil jacket tightening seal device of joining of the present invention has high pressure resistant, wear-resisting, contact surface abrasion and can compensate sealing, leak free advantage automatically.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Among the figure: body 1, cylinder body 2, external tapping 3, inner core 4, gland 5, wear-resisting circle 6, TB3 Che Shi sealing 7.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Figure 1, the strong seal arrangement that a kind of gas exhaust rig hydraulic chuck is joined oil jacket comprises body 1, cylinder body 2, external tapping 3, inner core 4, gland 5, wear-resisting circle 6 and TB3 Che Shi sealing 7.Body 1, cylinder body 2 connect in turn with external tapping 3, inner core 4 one ends put with body 1 in connect with gearwheel, the other end stretches out external tapping 3 and connects chuck: cylinder body 2 two ends are equipped with TB3 Che Shi sealing 7, wear-resisting circle 6 and gland 5, TB3 Che Shi sealing 7 press-fits between cylinder body 2 and inner core 4 through gland 5 sealings, TB3 Che Shi seals 7 cylindrical walls sealing applying cylinder body, 2 inwalls, and TB3 Che Shi seals 7 inner round wall through wear-resisting circle 6 sealing applying inner cores 4 outer walls; Wear-resisting circle 6 press-fits between cylinder body 2 and inner core 4 through gland 5 sealings, or 6 sealings of wear-resisting circle are arranged between gland 5 and the inner core 4.
Above-described embodiment is to explanation of the present invention, is not limitation of the invention, any scheme after the simple transformation of the present invention is all belonged to protection scope of the present invention.
