Abstract
The utility model relates to the technical field of a hoister sealing device, in particular to a hoister tail wheel sealing device which comprises a shell body, a hoister tail shaft, large cover bodies, small cover bodies and sealing pipes, wherein the large cover bodies are respectively arranged on the outer side surfaces at the two ends of the shell body in a fixed manner; concentric through holes are arranged on the large cover bodies and the small cover bodies; the inner diameter of the through holes on the large cover bodies is larger than that of the through holes on the small cover bodies; the inner end surfaces of the small cover bodies are fixed on the outer end surfaces of the large cover bodies; the outer end surfaces of the sealing pipes lean against the inner end surfaces of the small cover bodies, and are fixedly arranged together with the small cover bodies; lug bosses are arranged at the inner ends of the sealing pipes, and the inner diameter of the lug bosses is the same as that of the through holes of the small cover bodies. The device adopts reasonable and compact structure; as the sealing pipes are arranged on a sealing pressing cover, the service life of the sealing pressing cover is prolonged at the same time as a hoister tail wheel shaft is sealed; moreover, abrasion to the hoister tail wheel shaft is reduced and the production cost is lowered.
Description
Technical field
The utility model relates to lift seal arrangement technical field, is a kind of lift tail wheel seal arrangement.
Background technique
Present known lift tailing axle in use for some time, its tail stalk seal gland will serious wear, seals bad; cause Lou grey serious; befouling environment, tailing axle is levigate near housing section branch, can rupture when serious; need processing again or more renew axle; not only consuming time but also labor intensive financial resources also influence the ordinary production of enterprise, play seal action with two seal rings in the former gland; in case wearing and tearing just do not have seal action, and tailing axle is not had protective action.
Summary of the invention
The utility model provides a kind of lift tail wheel seal arrangement, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the problem that existing tail stalk seal gland seal performance is bad and easily cause tailing axle to damage.
The technical solution of the utility model realizes by following measure: a kind of lift tail wheel seal arrangement, comprise housing, the lift tailing axle, big lid, little lid and sealed pipe, big lid is fixedly mounted on respectively on the two ends outer side surface of housing, the through hole that concentric is arranged on big lid and the little lid, through hole internal diameter on the big lid is greater than the through hole internal diameter on the little lid, the interior edge face of little lid is fixed on the exterior edge face of big lid, the exterior edge face of sealed pipe withstands on the interior edge face of little lid and with little lid and is fixedly installed togather, in the inner of sealed pipe boss is arranged, the internal diameter of boss is identical with the internal diameter of the through hole of little lid, the two ends of lift tailing axle are passed the through hole on sealed pipe and the little lid respectively and are stretched out housing, are filled with stuffing box packing between sealed pipe and lift tailing axle.
Be further optimization and/or improvements below to above-mentioned model utility technological scheme:
Above-mentioned stuffing box packing can be adopted the graphite packing.
The exterior edge face of above-mentioned sealed pipe withstands on the interior edge face of little lid and can be fixedly installed togather by at least two bolt and little lid.
Between through hole on the above-mentioned little lid and the lift tailing axle seal ring can be installed.
Between above-mentioned boss and the lift tailing axle seal ring can be installed.
Above-mentioned big lid can be respectively bolt by at least two be installed on the two ends outer side surface of housing.
The utility model reasonable and compact in structure by sealed pipe is installed, thereby when the lift tail-gear spindle is sealed, has reduced the wearing and tearing to the lift tail-gear spindle working life of also having improved sealing gland on sealing gland, reduced cost of production.
Description of drawings
Accompanying drawing 1 is looked the sectional structure schematic representation for the master of the utility model most preferred embodiment.
Accompanying drawing 2 is the right TV structure schematic representation of big lid, little lid and lift tailing axle in the accompanying drawing 1.
Coding in the accompanying drawing is respectively: 1 is housing, and 2 is the lift tailing axle, and 3 is big lid, and 4 is little lid, and 5 is sealed pipe, and 6 is boss, and 7 are stuffing box packing, and 8 is bolt, and 9 is seal ring.
Embodiment
The utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
Shown in accompanying drawing 1,2, this lift tail wheel seal arrangement comprises housing 1, lift tailing axle 2, big lid 3, tegillum body 4 and sealed pipe 5; Big lid 3 is not fixedly mounted on the housing 1 two ends outer side surface; the through hole that concentric is arranged on big lid 3 and the tegillum body 4; through hole internal diameter on the big lid 3 is greater than the through hole internal diameter on the tegillum body 4; the interior edge face of tegillum body 4 is fixed on the exterior edge face of big lid 3; the exterior edge face of sealed pipe 5 withstands on the interior edge face of tegillum body 4 and with tegillum body 4 and is fixedly installed togather; boss 6 is arranged in the inner of sealed pipe 5; the internal diameter of boss 6 is identical with the internal diameter of the through hole of tegillum body 3; the two ends of lift tailing axle 2 are passed the through hole on sealed pipe 5 and the tegillum body 4 respectively and are stretched out housing 1; between sealed pipe 5 and lift tailing axle 2, be filled with stuffing box packing 7; like this; the effect that stuffing box packing 7 has been played seal action and protected lift tailing axle 2 not to be worn; wear and tear as discovery sealed pipe 5 during each the inspection; just to big lid 3; tegillum body 4 and sealed pipe 5 are changed; both reduce maintenance expenses and also alleviated personnel's labor intensity, and protected lift tailing axle 2 not to be worn.
