Abstract
The utility model relates to a sealing device for a stirring shaft of a concrete pump, and is suitable for a stirring system of the concrete pump. The utility model uses a stirring shaft which is combined by a left half shaft, a right half shaft and a middle shaft. The half shaft is provided with a sealing sleeve with a slurry baffle disc. The slurry baffle disc of the sealing sleeve corresponding to a flange of a motor is provided with a slurry discharge groove on the match surface of the side wall of a material hopper. An opening of the slurry discharge groove faces downwards, the abrasion life of bearings on both ends of the stirring shaft can be extended, and the use reliability of the stirring device is improved. Once a sealing rubber cup is damaged, the sealing rubber cup is disassembled and assembled without disassembling the whole stirring shaft, and thus the maintainability of the stirring device is improved.
Description
One, technical field
The utility model relates to concrete pump stirring shaft seal arrangement, is particularly useful for concrete pump.
Two, background technique
Be to improve the suction performance, prevent the concrete material segregation, all be provided with stirring apparatus in the hopper of concrete pump, its stirring shaft is bearing in one or two fluid motor-driven on the hopper left and right side wall by bearing.Because pump stirring shaft when work places among the concrete material fully, the sealability of its axle head is then extremely important.At present, the normal seal approach that adopts is: between stirring shaft and hopper internal face one sealing cup is set, in the stirring shaft mounting hole of hopper, a lip-type packing is set, the actual result that uses shows: adopt such sealing configuration, protection effect to the stirring shaft bearings at both ends is unsatisfactory, this mainly be because as the sealing cup of first road sealing directly with the contact of concrete material and with stirring 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 second road motive sealing, also can be damaged very soon, and concrete grout then leaks into bearing, aggravates the wearing and tearing of bearing.In addition, existing stirring shaft adopts overall structure, in case sealing cup damages when needing to change, then whole stirring apparatus must be unloaded, promptly time-consuming effort again.
Three, technology contents
(1) goal of the invention
In view of the deficiency of prior art, the object of the invention provides a kind of bearing wear that prevents to stir, and prolong to stir bearing working life, changes sealing cup concrete pump stirring shaft seal arrangement easily
(2) technological scheme
The utility model concrete pump stirring shaft seal arrangement, it comprise stirring shaft and be located on the stirring shaft by sealing cup, pressing plate, hopper side wall, lubricating cup, selfaligning roller bearing, the motor flange, the connection set that felt etc. are formed, stirring shaft is by a left side, right axle shaft and jack shaft are formed, and be fastening continuous by bolt and paddle bar between the three, be provided with the stuffing box gland of band baffle plate between semiaxis and the connection set, be provided with rotation lattice between the external cylindrical surface of stuffing box gland baffle plate and motor mounting flange left side endoporus and enclose, the fitting surface of corresponding motor flange of stuffing box gland baffle plate and hopper side wall is provided with lets out stock tank, and Open Side Down to let out stock tank.
The utility model concrete pump stirring shaft seal arrangement, semiaxis is bearing in the bearing hole of motor mounting flange by selfaligning roller bearing, be provided with O RunddichtringO and location sunk screw between stuffing box gland and the semiaxis, between stuffing box gland and the hopper side wall endoporus nylon jacket and y-type seal ring are housed, hopper side wall is provided with the passage that injects sealing cup lubricant oil.
(3) technique effect
The utility model concrete pump stirring shaft seal arrangement, be best suited in the concrete pump stirring system, employing is by the stirring shaft of left and right sides semiaxis and jack shaft combination, semiaxis is provided with the stuffing box gland of band baffle plate, the downward stock tank of letting out during stuffing box gland baffle plate place is provided with out, compared with the prior art, can prolong the wear-out life of stirring shaft bearings at both ends greatly, improve the operational safety of stirring apparatus; And in a single day sealing cup damages, and it is promptly dismantled and assembled to pull down whole stirring shaft, has improved the maintainalbility of stirring apparatus greatly, has practicability widely.
Four, description of drawings:
Accompanying drawing is a structural drawing of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is described further:
The utility model concrete pump stirring shaft seal arrangement, the stirring shaft that it mainly is made up of left and right half 2 and jack shaft 1, stuffing box gland 3, sealing cup 5, y-shaped ring 14, compositions such as nylon jacket 7 and selfaligning roller bearing 10.By the stirring shaft that left and right half 2 and jack shaft 1 are formed, fastening continuous between the three by bolt and paddle bar, in case sealing cup 5 damages when needing to change, need not whole axle is unloaded, as long as unload jack shaft.Semiaxis 2 is bearing in the bearing hole of motor mounting flange 11 by selfaligning roller bearing 10, semiaxis 2 is provided with stuffing box gland 3, and both Spielpassung are by two sunk screws, 13 location and fixing, for preventing that the concrete slip from leaking into bearing from this gap, is equipped with O RunddichtringO 12 therebetween.The right-hand member of stuffing box gland 3 is a baffle plate, is provided with rotation lattice between the external cylindrical surface of baffle plate and motor mounting flange 11 left endoporus and encloses 15.Sealing cup 5 is socketed on the external cylindrical surface of stuffing box gland 3, by O type circle 4 both is fitted closely, strengthens sealing effect, and is fastened on the internal face of hopper 8 by pressing plate 6 and screw.The hopper side wall 8 of supporting stirring shaft is provided with oil leab, centralized lubrication system by concrete pump provides lubricant grease for sealing cup 5, improve its service condition, and stop the immersion of concrete slip, nylon jacket 7 and y-type seal ring 14 are housed between bucket wall 8 endoporus and the stuffing box gland 3.Motor flange 11, by the seam location, is provided with lubricating cup 9 and reaches the oil duct that communicates with selfaligning roller bearing 10, and the felt 16 that prevents that lubricant oil from leaking is housed on the outer side surface of bucket wall 8 by screw on it.Effect by O RunddichtringO 12 and sealing cup 5, the fitting surface of adding corresponding motor flange 11 of stuffing box gland 3 baffle plates and bucket wall 8 is provided with lets out stock tank, Open Side Down to let out stock tank, prevent that effectively the concrete slip from leaking into bearing bore, O RunddichtringO 12 is a static seal, can keep good sealing effect and permanent working life, though sealing cup 5 has with stuffing box gland 3 relative movement is arranged, but because of its inner chamber is full of grease, can effectively improve its service condition, increase sealing effect, y-type seal ring 14 prevents the lubricant grease leakage on the one hand, on the other hand, in case sealing cup 5 damages, can stop the concrete slip to leak.Even extremely few concrete slip is arranged to be revealed along the periphery of stuffing box gland 3; after perhaps using a period of time; sealing cup 5 and y-type seal ring 14 all damage and when producing a large amount of concrete slips and leaking; the left end shelves slurry of stuffing box gland 3 is folded effect; fully the concrete slip shelves that leak are lived; and, prevent that it from leaking into bearing bore along letting out the stock tank outflow, bearing is played effective protective action.When after sealing cup 5 damages, needing to change, only need jack shaft 1 is unloaded, can the conveniently replaced sealing cup that has decreased 5.
