Description
Technical field:
The utility model relates to a kind of seal arrangement, and particularly a kind of sealing mechanism of new concrete stirring shaft belongs to concrete pump stirrer mechanism technical field.
Background technique:
At present, in the hopper of concrete pump, all be provided with stirring apparatus, purpose is the segregation that prevents concrete material; Wherein, stirring shaft is bearing on the hopper left and right side wall through bearing, and stirring shaft is by one or two fluid motor-driven; In above-mentioned structure, the seal approach that it adopted is: between stirring shaft and hopper internal face, one sealing cup is set, the seal ring of a lip is set in the stirring shaft mounting hole of hopper; But; In the use of reality, find, adopt this sealing configuration, unsatisfactory to the protection of stirring shaft bearings at both ends; Cause this result's main cause to be: as the sealing cup of first road sealing directly with the contact of concrete material and with stirring shaft mutual friction mutually, be easy to damage; In a single day leather cup damages, and the concrete material directly contacts with the lip-type packing that seals as second road, also can damage very soon, and concrete grout then leaks into bearing, the wearing and tearing of aggravation bearing; In addition, existing stirring shaft adopts overall structure, in case when sealing cup damages needs to change, then must whole stirring apparatus be unloaded, not only time-consuming, and require great effort.
The model utility content:
The purpose of the utility model is: a kind of stirring shaft seal is provided, overcomes existing above-mentioned defective in the existing technology.
The utility model realizes that the technological scheme that above-mentioned purpose adopted is: a kind of stirring shaft seal, and stirring shaft seal has circular flange lid, and the circular flange lid is installed in the left side of hopper; One O-ring seal is arranged between blind flange and hopper, and when mounted, the intermediate hole line of the axis of blind flange and hopper is on the same axis; Stuffing box gland is installed in the hopper intermediate hole, wherein, makes the flanged (FLGD) end of stuffing box gland be in the right positions of hopper; One " U " RunddichtringO is installed in the circular groove of hopper intermediate hole, and " U " RunddichtringO makes and forms sealing between the cylindrical of hopper and stuffing box gland, in the circular groove of blind flange intermediate hole; One " Y " RunddichtringO is installed; The seal ring of " Y " type makes between blind flange and the stuffing box gland and forms sealing relationship, and left and right sides semiaxis is installed in the intermediate hole of stuffing box gland, and one " O " RunddichtringO is installed in the circular groove on the semiaxis cylindrical of the left and right sides; " O " RunddichtringO makes between the intermediate hole of left and right sides semiaxis and stuffing box gland and forms sealing relationship; The motor mounting flange is through the right-hand member of Bearing Installation semiaxis in the left and right sides, and simultaneously, motor mounting flange and hopper are installed together; " O " RunddichtringO A is installed in the circular groove at stuffing box gland flange position; In the circular groove of motor mounting flange the right intermediate hole, install asphalt felt, jack shaft is installed together with fastening screw trip bolt and left and right sides semiaxis.
Beneficial effect: the utility model makes the concrete material in the hopper be difficult for arriving bearing owing to adopt above-mentioned seal arrangement, so; The life-span that bearing is not fragile, can prolong stirrer effectively; Simultaneously, jack shaft and left and right sides semiaxis are adopted the separated structures form, repair and replacement are saved time conveniently.
Description of drawings:
Fig. 1 is the structure principle chart of the utility model;
Shown in the figure: 1, jack shaft; 2, fastening screw trip bolt; 3, left and right sides semiaxis; 4, " O " RunddichtringO; 5, sealing snare; 6, blind flange; 7, " Y " RunddichtringO; 8, ring-like seal ring; 9, " U " RunddichtringO; 10, hopper; 11, motor mounting flange; 12, bearing; 13, asphalt felt; 14, " O " RunddichtringO A.
Embodiment:
Stirring shaft seal has circular flange lid 6, and circular flange lid 6 is installed in the left side of hopper 10, and an O-ring seal 8 is arranged between blind flange 6 and hopper 10; When mounted, the intermediate hole line of the axis of blind flange 6 and hopper 10 is on the same axis, and stuffing box gland 5 is installed in hopper 10 intermediate holes; Wherein, make stuffing box gland 5 flanged (FLGD) ends be in the right positions of hopper 10, one " U " RunddichtringO 9 is installed in the circular groove of hopper 10 intermediate holes; " U " RunddichtringO 9 makes and forms sealing between the cylindrical of hopper 10 and stuffing box gland 5, in the circular groove of blind flange 6 intermediate holes, one " Y " RunddichtringO 7 is installed; The seal ring 7 of " Y " type makes between blind flange 6 and the stuffing box gland 5 and forms sealing relationship, and left and right sides semiaxis 3 is installed in the intermediate hole of stuffing box gland 5, and one " O " RunddichtringO 4 is installed in the circular groove on left and right sides semiaxis 3 cylindricals; " O " RunddichtringO 4 makes between the intermediate hole of left and right sides semiaxis 3 and stuffing box gland 5 and forms sealing relationship; Motor mounting flange 11 is installed in the right-hand member of left and right sides semiaxis 3 through bearing 12, and simultaneously, motor mounting flange 11 is installed together with hopper 10; " O " RunddichtringO A14 is installed in the circular groove at stuffing box gland 5 flange positions; In the circular groove of motor mounting flange 11 the right intermediate holes, install asphalt felt 13, jack shaft 1 usefulness fastening screw trip bolt 2 is installed together with left and right sides semiaxis 3.
