Abstract
The utility model relates to an agitating sealing device for concrete delivering pump. An abrasion-proof sealing ring, a spacer flange and a bearing seat are orderly arranged on two ends of an agitating shaft connecting the hydraulic motor from inner side to outer side. An anti-friction bearing is arranged among the abrasion-proof sealing ring, the spacer flange and the agitating shaft. A sliding bearing is arranged between the bearing seat and the agitating shaft. An axle sleeve is arranged on the agitating shaft between an abrasion-proof axle sleeve and the sliding bearing. Two rotary sealing lattice coming rings are arranged between the spacer flange and the abrasion-proof axle sleeve. A leak hole is arranged between the two lattice coming rings. The pressure of the oil film between the abrasion-proof axle sleeve and the abrasion-proof annular seal of the utility model is higher than the pressure of concrete so that mortar of concrete can not filter in the clearance between the abrasion-proof axle sleeve and the abrasion-proof sealing ring. In case that the lubrication is lapsed, the damage of previous lattice coming ring causes leakage, because of another lattice coming ring for sealing before the agitating of the bearing, the mortar of concrete filtered in can be discharged through a mortar discharging hole. The agitating device can keep normal work for a while and doesn't need to stop immediately for maintenance.
Description
Technical field
The utility model relates to a kind of concrete conveying equipment, is specially a kind of concrete pump and stirs seal arrangement.
Technical background
Available coagulation soil transfer pump stirs sealing, adopts floating seal more, and the gap is bigger, and quality of lubrication oil is required height, and fuel consumption is also big.Because the gap is big, the concrete mortar easily infiltrates and stirs in the bearing, causes easily and stirs the bearing premature wear, makes the stirring mechanism cisco unity malfunction, shortens service life of equipment.
Summary of the invention
The purpose of this utility model is that a kind of good sealing effect will be provided, and can guarantee that the concrete pump of stirring mechanism energy proper functioning stirs seal arrangement.
The technical solution of the utility model is: at the stirring shaft two ends that connect oil hydraulic motor, with the concrete hopper contacting point, by outward interior, wear-resistant seal ring, counter flange, bearing support are housed successively.Between wear-resistant seal ring, counter flange and stirring shaft, anti-friction bearing is housed; Between bearing support and stirring shaft, sliding bearing is housed; On the stirring shaft between anti-wear sleeve and the sliding bearing, axle sleeve is housed.Between counter flange and anti-wear sleeve, two rotary seal lattice are housed enclose, between enclosing, two lattice have Leak hole.
The utility model uses special lubricant pump fuel feeding, forms the oil film that one deck has certain pressure between anti-wear sleeve and wear-resistant seal ring, and than hopper inner concrete pressure height, the concrete mortar can not infiltrate the gap between anti-wear sleeve and the wear-resistant seal ring.Because anti-wear sleeve and wear-resistant seal are with special metallic material manufacturing, even under the bad situation of lubricating condition, also can work considerable time.Just in case lubrication failure, previous lattice enclose damage; or because of long-term use; anti-wear sleeve and the wearing and tearing of wear-resistant seal ring are excessive; cause spillage; because the stirring shaft brought forward also has a Doug to enclose sealing; the concrete grout that leaks into also can be released by slurry discharging hole, but stirring mechanism proper functioning a period of time does not still need hard stop to repair.
Description of drawings
Accompanying drawing is the utility model sectional view.
Among the figure 1, oil hydraulic motor, 2, bearing support, 3, sliding bearing, 4, axle sleeve, 5, anti-wear sleeve, 6, stirring shaft, 7, the wear-resistant seal ring, 8, counter flange, 9, Ge Laiquan, 10, Leak hole, 11, oilhole, 12, O shape circle, 13, mix the earth hopper.
Embodiment
Introduce the utility model below in conjunction with accompanying drawing.
With reference to accompanying drawing, one end of the stirring shaft 6 that is connected with oil hydraulic motor 1 rotating shaft, a bearing support 2 is arranged outside stirring shaft, bearing support one end is fixed by bolt and oil hydraulic motor, the bearing support the other end is by the axle bed of bolt connection counter flange 8 and hopper 13, and the counter flange the other end connects wear-resistant seal ring 7 by bolt.Between wear-resistant seal ring 7, counter flange 8 and the stirring shaft 6, anti-wear sleeve 5 is housed, anti-wear sleeve is fixed on the stirring shaft and rotates with axle.Anti-wear sleeve and wear-resistant seal ring adopt Spielpassung, and both constitute primary seal of the present utility model.Two rotary seal lattice are housed between counter flange 8 and the anti-wear sleeve 5 to be enclosed 9, two lattice and has Leak hole 10 between enclosing.There is oilhole 11 to communicate between counter flange 8 and the wear-resistant seal ring 7.Between bearing support 2 and stirring shaft 6, sliding bearing 3 is housed.On the stirring shaft between anti-wear sleeve 5 and the sliding bearing 3, axle sleeve 4 is housed also.Between counter flange and the hopper axle bed, between anti-wear sleeve and the stirring shaft, between wear-resistant seal ring and the counter flange static seal O shape circle 12 is housed all.
Pass the other end of the stirring shaft 6 of concrete hopper 13, above-mentioned identical seal arrangement is arranged, connecting end cap on the stirring shaft bearing at end seat.
