The technical problems are solved, and the conveying belt riding wheel of the chain type scraper has a supporting function on a chain which is used for a long time and is lengthened, so that the contact friction of the chain and a sliding chute, a chain wheel and carried goods is reduced. According to the technical scheme, the conveying belt riding wheel of the chain type scraper comprises a wheel shaft and a hub, the wheel shaft penetrates through the center where the hub is placed, the hub rotates around the wheel shaft, a supporting block is tightly attached to the lower portion of the wheel shaft, a supporting bar is tightly attached to the lower portion of the supporting block, and the supporting bar penetrates through a supporting nut. After the chain is used for a long time and is lengthened, the conveying belt riding wheel of the chain type scraper can have the supporting function on the chain and prevent the contact friction of the chain and the sliding chute, the chain wheel and the carried goods. In addition, by means of the conveying belt riding wheel of the chain type scraper, the height of a tray can be adjusted flexibly according to actual needs, so that the riding wheel is more flexible. The conveying belt riding wheel of the chain type scraper can be applied to equipment such as chain type scrapers.
Description
Technical field
The utility model relates to chain scraper machine conveyer, especially a kind of chain scraper machine belt conveyor support roller.
Background technology
Chain scraper machine conveyer is using scraper chain as trailer coupling, after head transmission position starts, drive the rotation of head axle upper sprocket wheel, make scraper chain circular flow drive material to move along chute, until to the unloading of machine top portion, scraper chain is walked around to scrape to take turns and is done stepless closed cycle operation, completes the conveying of material.
Scraper chain is conveyer important component part, is also weakest part.In material conveying process, chain running velocity changes, and in the time that engagement point engagement starts, speed is positive peak, and along with sprocket wheel rotation, speed reduces to zero gradually, then reaches negative peak.During to another sprocket engagement, the running velocity of chain becomes positive peak from negative peak again.Therefore, need to bear larger static weight and live load in chain movement, cause moving elastic elongation after a period of time, tensile force diminishes.Elongated chain causes abrasion in contact frictions such as operational process and chute, sprocket wheel, institute's cargo, weakens chain link section, causes strength decreased, occurs " jumping chain " and phenomenon of rupture.And to increase tensile force, and can only carry out tight chain to chain, this has accelerated again the wearing and tearing of chain, and occurs when " chain jamming " not cushion leeway, and directly chain rupture forms vicious circle.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly plays a supporting role to chain elongated after long-term use, thereby reduces the chain scraper machine belt conveyor support roller of chain and chute, sprocket wheel, institute's cargo contact friction.
The utility model solves the technical scheme that its technical matters adopts: chain scraper machine belt conveyor support roller, comprise wheel shaft and wheel hub, described wheel shaft rotates around wheel shaft through the center of circle and the wheel hub at wheel hub place, below wheel shaft, be close to and be provided with tray, below described tray, be close to and be provided with strut bar, strut bar is through holding nut.
Further, comprise position limiting slide block, described position limiting slide block includes chute, and wheel shaft and tray are all arranged in described chute.
Further, the contact surface of tray and strut bar is ball recess, and the contact surface of strut bar and described ball recess is spherical convex surface.
Further, on strut bar, be provided with through hole.
The beneficial effects of the utility model are: the utility model in use, is positioned over chain below, and holding nut is fixed in the main body of equipment.Chain is long-term elongated after using after, the utility model can be played a supporting role and prevent chain and chute, sprocket wheel, institute's cargo contact friction chain.In addition, the utility model can be with the height of actual needs flexible pallet, and described regulative mode is; By rotary support bar, can regulate the height of strut bar, thereby by regulating wheel shaft height to regulate the height of wheel hub, allow the utility model have more alerting ability.The utility model can be applied in the equipment such as chain scraper machine.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the utility model is arranged at chain scraper machine.
Fig. 2 is schematic diagram of the present utility model.
In figure, be labeled as: support roller 1, wheel hub 11, wheel shaft 12, position limiting slide block 13, chute 131, tray 14, ball recess 141, strut bar 15, spherical convex surface 151, through hole 152, holding nut 16, chain 2, driving wheel 3.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Chain scraper machine belt conveyor support roller as shown in Figure 1 and Figure 2, comprise wheel shaft 12 and wheel hub 11, described wheel shaft 12 rotates around wheel shaft 12 through the center of circle and the wheel hub 11 at wheel hub 11 places, wheel shaft 12 belows are close to and are provided with tray 14, described tray 14 belows are close to and are provided with strut bar 15, and strut bar 15 is through holding nut 16.
In the time that reality is used, first need holding nut 16 to be fixed on the inwall of chain scraper machine.Owing to being close to and being provided with tray 14 in wheel shaft 12 belows, and tray 14 belows are close to and are provided with strut bar 15, in the time that needs regulate wheel shaft 12 height, only need rotary support bar 15.
Shown in Fig. 1 is the schematic diagram that the utility model is arranged at chain scraper machine, and driving wheel 3 chain drive-belts 2 move, at the use initial stage.Chain 2 does not directly contact with wheel hub 11.After long in use, chain 2 is elongated and contacts with wheel hub 11.Now wheel hub 11 is supporting chain 2.Sometimes in order to allow wheel hub 11 better by support chains 2, can rotary support bar 15, because described strut bar 15 is through holding nut 16, so strut bar 15 can up or down regulate height with hand of rotation, thereby regulate the height of wheel hub 11.
For accommodating support block 14 is from wheel shaft 12 below slippages, can select such scheme: comprise position limiting slide block 13, described position limiting slide block 13 includes chute 131, and wheel shaft 12 and tray 14 are all arranged in described chute 131.As shown in Figure 2, position limiting slide block 13 can be limited to wheel shaft 12 and tray 14 in chute 131, prevents that tray 14 is from, wheel shaft 12 below slippages.
Further, tray 14 and the contact surface of strut bar 15 can be designed to ball recess 141, strut bar 15 is spherical convex surface 151 with the contact surface of described ball recess 141.As shown in Figure 2, ball recess 141 matches each other and contacts with spherical convex surface 151.There is most the way of contact of choosing, the radius of curvature of ball recess 141 can also be designed to be greater than the radius of curvature of spherical convex surface 151, thereby guarantee that ball recess 141 is that point contacts with spherical convex surface 151, higher to the adjustment precision of wheel hub 11 height like this.
For more laborsaving when the rotary support bar 15, through hole 152 can be set on strut bar 15.As shown in Figure 2, iron rod, crowbar etc. can be inserted to through hole 152, utilize lever raw material rotary support bar 15, realize more labour-saving and drive strut bar 15.
