Abstract
The invention relates to a sealing device for a stirring shaft of a concrete pump. The sealing device is characterized in that a plurality of sealing rings are mounted between support bearings in sequence and a corresponding specific structure is adopted. Concrete in a hopper is difficult to arrive at the bearings, thereby protecting bearings from being damaged easily and efficiently prolonging service life of a stirring machine. Meanwhile, since a structure in which a middle shaft is separated from left and right half shafts is adopted, the operations of replacement and repair become time-saving and convenient.
Description
Technical field:
The present invention relates to a kind of structure of concrete pump shaft, particularly a kind of concrete stirs shaft seal, belongs to concrete pump mixer technical field of structures.
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: provide a kind of concrete pump to stir shaft seal, overcome 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 concrete pump stirs shaft seal, and it is made up of jackshaft, trip bolt, left and right sides semiaxis, " O " RunddichtringO, sealing snare, blind flange, " Y " RunddichtringO, ring-like sealing ring, " U " RunddichtringO, hopper, motor mounting flange, bearing, asphalt felt.It is characterized in that: the circular flange lid is fixed on the hopper left side, use the O-ring seal sealing between blind flange and the hopper, simultaneously, 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 the flanged (FLGD) end of sealing shroud is in the right positions of hopper, in the cannelure of the interstitial hole of hopper, " U " RunddichtringO is installed, should " U " RunddichtringO make to form between the cylindrical of hopper and sealing shroud and seal, in the cannelure of blind flange interstitial hole, the sealing ring of " Y " type is installed, the sealing ring of " Y " type of being somebody's turn to do makes between blind flange and the sealing shroud and forms sealing relationship, described left and right sides semiaxis is installed in the sealing shroud interstitial hole, " O " RunddichtringO is installed in the cannelure on the semiaxis cylindrical of the left and right sides, this " O " RunddichtringO makes the interior sealing relationship that forms of the interstitial hole of left and right sides semiaxis and sealing shroud, described motor mounting flange is installed in the right-hand member of left and right sides semiaxis by bearing, simultaneously, motor mounting flange and hopper install and fix together with securing member, in the cannelure at the flange position of sealing shroud, " O " RunddichtringO is installed, simultaneously, the cannelure of the interstitial hole on the right of the motor mounting flange is installed asphalt felt.
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.
