Abstract
The invention discloses a novel sealing mechanism for a mixer shaft. A U-shaped sealing ring is arranged in an annular groove of a middle hole of a hopper to form sealing between the hopper and the excircle of a sealing sleeve; a Y-shaped sealing ring is arranged in the annular groove of the middle hole of a blind flange to form a sealing relation between the blind flange and the sealing sleeve; a left-right half-shaft is arranged in the middle hole of the sealing sleeve; an O-shaped sealing ring is arranged in the annular groove on the excircle of the left-right half-shaft to form a sealing relation between the left-right half-shaft and the middle hole of the sealing sleeve; a motor mounting flange is arranged at the right end of the left-right half-shaft by a bearing to be mounted together with the hopper; and an O-shaped sealing ring A is arranged in the annular groove in the flange part of the sealing sleeve.
Description
Technical field:
The present invention relates to a kind of sealing mechanism of shaft, particularly a kind of sealing mechanism of new concrete shaft belongs to concrete pump mixer mechanism technical field.
Background technology:
At present, in the hopper of concrete pump, all be provided with agitating device, purpose is the segregation that prevents concrete material; Wherein, shaft is bearing on the hopper left and right sides wall through bearing, and shaft is by one or two fluid motor-driven; In above-mentioned structure, the seal approach that it adopted is: between shaft and hopper internal face, one sealing cup is set, the sealing ring of a lip is set in the shaft installing hole of hopper; But; In the use of reality, find, adopt this hermetically-sealed construction, unsatisfactory to the protection of 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 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 shaft adopts overall structure, in case when sealing cup damages needs to change, then must whole agitating device be unloaded, not only time-consuming, and require great effort.
Summary of the invention:
The objective of the invention is to: a kind of sealing mechanism of novel shaft is provided, overcomes existing above-mentioned defective in the prior art.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of sealing mechanism of novel shaft, and it is that sealing mechanism by shaft has circular flange lid, 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 interstitial hole line of the axis of blind flange and hopper is on the same axis; Sealing shroud is installed in the hopper interstitial hole, wherein, makes the flanged (FLGD) end of sealing shroud be in the right positions of hopper; One " U " RunddichtringO is installed in the cannelure of hopper interstitial hole, and " U " RunddichtringO makes and forms sealing between the cylindrical of hopper and sealing shroud, in the cannelure of blind flange interstitial hole; One " Y " RunddichtringO is installed; The sealing ring of " Y " type makes between blind flange and the sealing shroud and forms sealing relationship, and left and right sides semiaxis is installed in the interstitial hole of sealing shroud, and one " O " RunddichtringO is installed in the cannelure on the semiaxis cylindrical of the left and right sides; " O " RunddichtringO makes between the interstitial hole of left and right sides semiaxis and sealing shroud and forms sealing relationship; The motor mounting flange is installed in the right-hand member of left and right sides semiaxis through bearing, and simultaneously, motor mounting flange and hopper are installed together; " O " RunddichtringO A is installed in the cannelure at sealing shroud flange position; In the cannelure of motor mounting flange the right interstitial hole, install asphalt felt, jackshaft is installed together with trip bolt and left and right sides semiaxis.
Beneficial effect: the present invention makes the concrete material in the hopper be difficult for arriving bearing owing to adopt above-mentioned sealing mechanism, so; The life-span that bearing is not fragile, can prolong mixer effectively; Simultaneously, jackshaft 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 a structure principle chart of the present invention;
Shown in the figure: 1, jackshaft; 2, trip bolt; 3, left and right sides semiaxis; 4, " O " RunddichtringO; 5, sealing snare; 6, blind flange; 7, " Y " RunddichtringO; 8, ring-like sealing ring; 9, " U " RunddichtringO; 10, hopper; 11, motor mounting flange; 12, bearing; 13, asphalt felt; 14, " O " RunddichtringO A.
The specific embodiment:
The sealing mechanism of shaft 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 interstitial hole line of the axis of blind flange 6 and hopper 10 is on the same axis, and sealing shroud 5 is installed in hopper 10 interstitial holes; Wherein, make sealing shroud 5 flanged (FLGD) ends be in the right positions of hopper 10, one " U " RunddichtringO 9 is installed in the cannelure of hopper 10 interstitial holes; " U " RunddichtringO 9 makes and forms sealing between the cylindrical of hopper 10 and sealing shroud 5, in the cannelure of blind flange 6 interstitial holes, one " Y " RunddichtringO 7 is installed; The sealing ring 7 of " Y " type makes between blind flange 6 and the sealing shroud 5 and forms sealing relationship, and left and right sides semiaxis 3 is installed in the interstitial hole of sealing shroud 5, and one " O " RunddichtringO 4 is installed in the cannelure on left and right sides semiaxis 3 cylindricals; " O " RunddichtringO 4 makes between the interstitial hole of left and right sides semiaxis 3 and sealing shroud 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 cannelure at sealing shroud 5 flange positions; In the cannelure of motor mounting flange 11 the right interstitial holes, install asphalt felt 13, jackshaft 1 usefulness trip bolt 2 is installed together with left and right sides semiaxis 3.
