Description
Technical field
The utility model relates to a kind of assembly and mounting structure of overhead traveling crane configuration.Belong to the travelling overhead crane apparatus technical field.
Background technology
Horizontal wheel is the advanced parts of overhead traveling crane configuration, the basic goal of overhead traveling crane configuration level wheel is that the cliding friction that becomes wheel rim and track is friction of rolling, reduce the wearing and tearing of online wheel and track, improve the equipment on-line life-span, and possess guiding and deviation-correcting function to overhead traveling crane running orbit correctness.Pass through operation examination on site, horizontal wheel is becoming cliding friction in the friction of rolling process, and self is stressed larger, and its main power is the diametral load perpendicular to track, horizontal wheel bearing principal parameter can guarantee, but being uneven of track also causes larger axial force to horizontal wheel simultaneously.The structure of horizontal wheel can not satisfy actual requirement at present, has increased the trouble point to overhead traveling crane, has affected overhead traveling crane operation stability and efficient.
Specifically, at present overhead traveling crane configuration roughly has two kinds of structures than the advanced level wheel.
The first structure is the centering that horizontal wheel is used eccentric shaft adjustment and track, uses self-aligning roller bearing to guarantee load all the time facing to axle, the elimination axial force.Its advantage is the reasonable clearance that can guarantee by adjusting at any time the axle corner horizontal wheel and track, eliminated the diametral load of horizontal wheel and track friction generation to the damage of bearing, but also there is following shortcoming in its structure: the centripetal adjustment of horizontal wheel causes the top seal life-span extremely short; Internal bearings is moved badly because dust and top seal chip, iron filings etc. enter after top seal damages, and the life-span is short; Bearings mounted axle cover only depends on several bolts to be connected with eccentric shaft, and intensity is low, causes horizontal wheel easily to come off, and causes the problems such as online overhead traveling crane malfunction shutdown.
The second structure is that horizontal wheel is used a pair of self-aligning roller bearing bearing radial force, use the centering of eccentric shaft adjustment and track, its advantage is that bearing uses in pairs, and the ability of bearing radial force is high, and the bearing lubrication situation is good, the axial force that horizontal wheel and track friction produce is shared by two bearings, bearing life is longer, and shortcoming is: horizontal wheel can not move with rail height, thereby has cliding friction, wearing and tearing are severe, and the axial force that horizontal wheel and track friction produce is larger; Bearings mounted axle sleeve is combined with eccentric shaft and is relied on several bolts to fix, and undercapacity, horizontal wheel assembly cause causing the problems such as online overhead traveling crane malfunction shutdown to come off.
Present stage, horizontal wheel was was all installed and used in groups by enclosed baffle, and every group of horizontal wheel of its a kind of horizontal wheel more reaches 4 when using, and volume is comparatively huge, and disposable infusion of financial resources is more in the construction.
Existing overhead traveling crane horizontal wheel generally adopts the installation method that is completely fixed in the horizontal surface, have non-removable characteristics in horizontal surface, changing an online horizontal wheel needs time-consuming to reach several hours, and must rest in several fixed locations that special-purpose maintenance suspender is arranged on the factory building top, the mobile lifting tool such as perhaps use that vapour hangs, it is low to change horizontal wheel efficient, worker's labour intensity is large, in case online horizontal wheel fault, to affect for a long time this regional production, even this regional production is paused, cause huge benefit-cost loss.
Other horizontal wheel is more backward, and fault rate is higher, and guiding and rectifying effect are poorer.
The utility model content
Technical problem to be solved in the utility model provides that a kind of overhead traveling crane horizontal wheel bearing is not fragile, horizontal wheel can not come off, the gap between horizontal wheel and the track rationally, dismounting overhead traveling crane horizontal wheel very easily.
The technical scheme that solves the problems of the technologies described above is:
A kind of overhead traveling crane horizontal wheel, it comprises horizontal wheel shaft, horizontal wheel, bearing, its improvements are, the axle head of its horizontal wheel shaft has the shaft shoulder of high thickness and high altitude, bearing is two radial bearings, two bearings are sleeved on up and down the shaft shoulder top of horizontal wheel shaft successively, are set with excentric sleeve on the top of horizontal wheel shaft, and excentric sleeve and horizontal wheel pedestal are fastenedly connected.
Above-mentioned overhead traveling crane horizontal wheel, be connected with horizontal adapter plate on the described horizontal wheel pedestal, the front end of horizontal adapter plate has opening, the bottom of opening is circular shape, and the distance between the opening both sides is complementary with the external diameter of excentric sleeve, in the top and bottom of horizontal adapter plate the detouchable baffle plate is arranged, one side of baffle plate has opening, the bottom of opening is circular shape, and the distance between the opening both sides is complementary with the external diameter of excentric sleeve, between baffle plate and the horizontal adapter plate tie bolt is arranged.
Above-mentioned overhead traveling crane horizontal wheel, two overhead traveling crane horizontal wheel of parallel installation on the described horizontal wheel pedestal.
The beneficial effects of the utility model are:
Possess the shaft shoulder of high thickness and high altitude on the horizontal axle stub, lost efficacy even can guarantee bearing failure, horizontal wheel can not come off yet; Use paired radial bearing to eliminate the microcosmic unbalanced stresses; Adjustment excentric sleeve angle position can be adjusted the gap between horizontal wheel and the track; The horizontal wheel pedestal that horizontal wheel is installed adopts removable structure, and dismounting is very convenient.The utility model is rational in infrastructure, has guaranteed that the overhead traveling crane horizontal wheel can not come off, regulate that the gap is simple, dismounting is quick and convenient, has improved production efficiency effectively.
