Background technique
Sealing is the means that in mechanized equipment, modal protection bearing etc. needs closed operation workpiece, and different as requested, sealing device structure, the feature of design are also different.As patent publication No. a kind of film bearing seal device disclosed in CN103104612A, comprise tapered sleeve, roll, lining, bearing support and sealing cover, roll is provided with sealing cover, and sealing cover is connected with bearing support, the opposing side of sealing cover and bearing support is provided with oil trap, and on roll, cover has seal ring; Seal ring is provided with throws oily lip and sealing lip; Throw oily lip and stretch to the space that bearing support and sealing cover surround; Sealing lip is L-shaped; " I " portion of " L " shape sealing lip contacts with sealing cover; The below of sealing cover is provided with center flange; On roll, cover has sealing outer shroud; Sealing outer shroud is connected with sealing cover; Seal ring is provided with aluminum ring device with the outer interannular of sealing; On roll, cover has water ring; Water ring contacts with sealing outer shroud.And for example a kind of heavy roller bearing seal cover of providing for CN101979289A of patent publication No., comprise steel pipe, bearing, axle, vinyl cover, the exterior edge face of bearing is pressed with vinyl cover, the outer rim of vinyl cover press-fits the closing in inwall in steel pipe, the periphery of the inner edge laminating axle of vinyl cover, vinyl cover comprises inner cap, enclosing cover, the nested exterior edge face being loaded on inner cap of enclosing cover interior edge face.These devices all cannot be used for the sealing of the horizontal pulp injection tank of shield machine above.
Horizontal pulp injection tank seal arrangement is auxiliary device important in shield machine, and its Main Function seals the slurries in horizontal pulp injection tank and stirring shaft.Due to the particularity of mud, the sealing difficulty of horizontal pulp injection tank is comparatively large, and conventional sealing means all requires very high for use and regular maintenance, and uses pulp injection tank soon to there will be the spillage phenomenon at stirring shaft two ends, causes negative effect to construction.
Summary of the invention
The purpose of this utility model is to solve existing sealing means in the horizontal pulp injection tank of shield machine, its regular maintenance requires very high, working life is short, often there is stirring shaft two ends spillage phenomenon, affect construction speed, increase the problem of construction cost, provide a kind of shield machine horizontal pulp injection tank seal arrangement.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the horizontal pulp injection tank seal arrangement of a kind of shield machine, comprise the capping being positioned at bearing support one end, it is characterized in that being provided with axle sleeve between described bearing support and stirring shaft, the inner hole part that axle sleeve outer ring coordinates with bearing support is provided with cover exterior seal ring, is provided with cover inner seal ring between inner hole of shaft sleeve and stirring shaft; Described capping and bearing support fitting surface are provided with grease groove, and grease groove communicates with the grease channel in bearing support.The technical program adopts a kind of unconventional seal form, avoids the Sealing of relative movement directly to contact with cement slurry, thus stops the wearing and tearing of cement slurry to seal element, to reach sealing effect.Furtherly, make relative movement not to occur, to avoid the wearing and tearing of Sealing between the Sealing that likely occurs with cement slurry directly to contact and rotatingshaft by change structure; And will the gap design between opposed moving members be had to become labyrinth seal structure, and it be made to be full of grease.Guarantee there is the continual injection of seal grease when stirring shaft rotates by chain control, cause to reduce human error the possibility that sealing is failed.
As preferably, described capping and the fitting surface of bearing support are provided with the concavo-convex bar groove cooperatively interacted.Concavo-convex bar groove is the concentric circle raised line that cooperatively interacts of capping and bearing support and concentric annular grooves, has both been conducive to both assembling and positioning, and can have formed labyrinth seal structure again.
As preferably, between described capping and stirring shaft, be provided with lidstock circle.
As preferably, described bearing support outer ring and body joint are provided with body seal ring.
As preferably, described capping outer ring has at least position to be arranged in the endoporus of body.Owing to being full of grease between capping and bearing support, concavo-convex bar groove structure together with capping outer ring can become with the dislocation of body endoporus, avoids mud to fling fitting surface.
As preferably, described grease slot is outside the cover inner seal ring of axle sleeve.Separate Sealing completely to contact with cement slurry.
As preferably, described cover exterior seal ring is provided with more than two pieces and two pieces, is provided with grease mouth between adjacent two cover exterior seal rings.
As preferably, described body seal ring be respectively equipped with grease mouth along its axial both sides.Seal ring is protected by grease.
The beneficial effects of the utility model are: the reliability increasing substantially the sealing of horizontal pulp injection tank; Avoid the seal failure that artificial origin causes; Ensure that construction speed, reduce construction cost.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the partial enlargement structural representation of the utility model Fig. 1.
In figure: 1. overlap exterior seal ring, 2. overlap inner seal ring, 3. body seal ring, 4. grease groove, 5. lidstock circle, 6. capping, 7. stirring shaft, 8. axle sleeve, 9. bearing support.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
The horizontal pulp injection tank seal arrangement of a kind of shield machine of the present embodiment, see Fig. 1, bearing is installed in stirring shaft 7 end, and bearing is arranged in bearing support 9, and outside end cap fastens.
