Abstract
The invention discloses a novel sealing mechanism of a concrete pump stirring shaft. The annular slot of a hopper center hole is internally provided with a U-shaped sealing ring; the U-shaped sealing ring causes the hopper and the excircle of a gland cover to be sealed; a Y-shaped sealing ring is installed in the annular slot of the hopper center hole of a flange cover and causes the flange cover and the gland cover to be sealed; a left and right half shaft is installed in the center hole of the gland cover; an O-shaped sealing ring is installed in the annular slot on the excircle of the left and right half shaft and causes the left and right half shaft and the center hole of the gland cover to be sealed; a motor mounting flange is installed on the right end of the left and right half shaft by a bearing; the motor mounting flange and the hopper are installed together; and the O-shaped sealing ring A is installed in the annular slot of the gland cover gland.
Description
Technical field:
The present invention relates to a kind of mechanism of concrete pump 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 by 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 one 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; Leather cup is in case damage, and the concrete material directly contacts with lip-type packing as the sealing of second road, also can damage very soon, and concrete grout then leaks into bearing, aggravates the wearing and tearing of bearing; In addition, existing shaft adopts overall structure, in case sealing cup damages when needing to change, then whole agitating device must be unloaded, and is not only time-consuming, and effort.
Summary of the invention:
The objective of the invention is to: a kind of sealing mechanism of new concrete pump 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 new concrete pump shaft, it is by sealing mechanism one circular flange lid to be arranged, the circular flange lid is installed in the left side of hopper, one O-ring seal is arranged between blind flange and hopper, 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, make 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, " 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, left and right sides semiaxis is installed in the interstitial hole of sealing shroud, 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 by bearing, 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 device, 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.
