Abstract
The utility model relates to an inlaid plate type chain belt chain wheel apparatus for a hopper lifter, which realizes transmission by using the cooperation of chain wheels with trapezoidal grooves and plate type chain links as well as chain belts. The wheel rim of each chain wheel is provided with at least three trapezoidal grooves, chain plates are engaged with the trapezoidal grooves, and the inner and the outer chain plates of each of the chain links are mutually staggered in parallel. Both ends of each of the chain plates are provided with axle holes which are fixed by pin axes. The bottom edges of the inner and the outer chain plates are provided with radians corresponding to the chain wheels. The utility model can use a single chain structure or a double-chain structure, having the advantages of stable running, reliability, no impact, no noise, adoptability to both new lifters and old lifters, high wear resistance and intensity, and long service life which is five times that of an original apparatus.
Description
The utility model belongs to the building material machinery bucket type is promoted, with the improvement of transmission part, particularly to the improvement of bucket elevator chain sprocket device.
Existing bucket elevator adopts the loop chain transmission to promote, friction force is big between the chain link, particularly chain link is in the serious dust work environment, dust falls into chain link, has more increased the weight of abrasion, along with the increase of abrasion, required tensile force is also big more, power consumption is also just many more, and general chain just needs a complete set of the replacing about half a year, sprocket wheel about 1 year, increased the maintenance of equipment expense.
The purpose of this utility model is to overcome the defective that above-mentioned driving device brings, design and a kind ofly can reduce abrasion greatly, improve service life, do not need a complete set of the replacing, and the attached board-like chain chain gear apparatus of the edge that is used for bucket elevator that the replacement cycle of indivedual consumable accessorys can prolong greatly.
The utility model is to adopt the incompatible transmission of finishing that matches of the sprocket wheel of band trapezoidal groove and leaf chain pitch chain bar.Concrete structure is: have 3 trapezoidal grooves on the wheel rim of sprocket wheel at least.Carrier bar and dovetail groove on the chain link of formation chain match, and the inner plate of each chain link and pin link plate are parallel to each other staggered, and the inner plate of each chain link and pin link plate are respectively in one plane.Interior pin link plate two ends have axis hole, and the fixing carrier bar of axis hole of pin link plate in bearing pin (1) passes has the radian that adapts with sprocket wheel with the contacted interior pin link plate base of sprocket wheel trapezoidal groove.
The utility model can be selected strand formula or duplex structure for use, when adopting single-stranded structure, have 3 trapezoidal grooves on the chain wheel rim, each chain link has two pin link plates and an inner plate, two pin link plates parallel, inner plate and parallel with pin link plate staggered is housed between the pin link plate, and 3 interior pin link plates move in sprocket wheel groove separately.Open 4 trapezoidal grooves on the wheel rim of sprocket wheel when adopting duplex structure, each chain link has a pin link plate, another piece pin link plate is replaced by arm-tie, it between pin link plate and the arm-tie inner plate, 2 interior pin link plates of each chain link move in sprocket groove separately in every chain, arm-tie does not occupy groove, only plays balance and reinforces bearing pin.
The utility model is compared with existing driving device has following advantage:
1, this device operates steadily, reliably, does not impact and noise, and hoisting capacity is strong, owing to adopt carrier bar and pin shaft structure, has avoided the loop chain welding process, only needs assembling to get final product;
2, owing to select superior alloy steel and the design's structure, resistance to abrasion and intensity improve greatly, and be more than 5 times of original device service life, do not need a complete set of the replacing, only need to change indivedual consumable accessorys, as inlay attached metallic sheath and adhesive tape, and the replacement cycle prolongs greatly;
3, because chain revolution position has installed sealing arrangement additional, the friction of having avoided dust pollution to bring, this device not only can be used for bucket elevator, also is applicable to some load transfer devices, to existing also replaceable this device of one-tenth of gig.
Doing one below by accompanying drawing in conjunction with embodiment of the present utility model describes in detail:
Fig. 1 is installed in the external form scheme drawing of bucket elevator for the utility model.
Fig. 2 is the double-stranded bar chain link cutaway view along A-A direction among Fig. 1.
Fig. 3 is the carrier bar front view.
Fig. 4 is the carrier bar cutaway view along B-B direction among Fig. 3.
Fig. 5 is the sprocket wheel section-drawing along C-C direction among Fig. 1.
Fig. 6 is a strand bar chain link cutaway view.
Referring to Fig. 1～Fig. 6, be contained on sprocket wheel 14 wheel rims of gig arbor 13 and have 3 or 4 trapezoidal grooves 10, chain 15 is made up of a plurality of chain links, each carrier bar that is listed as on the same plane moves in groove separately, and match with dovetail groove 10, when adopting the single-stranded structure (see figure 6), open 3 dovetail grooves on the wheel rim of sprocket wheel 14, each chain link respectively has an inner plate 7 and two pin link plates 4, be inner plate 7 between two pin link plates, parallel staggered between the interior pin link plate, the inner plate of each chain link and pin link plate are respectively in one plane.When adopting the duplex structure (see figure 2), open 4 dovetail grooves on the wheel rim of sprocket wheel 14, each chain link has a pin link plate 4, and the position of another piece pin link plate arm-tie 11 that changes the outfit is inner plate between pin link plate and the arm-tie.Have axis hole 6 at interior pin link plate or arm-tie two ends, bearing pin 1 places the hole to fix carrier bar and arm-tie, has radian with the contacted interior pin link plate base of dovetail groove, and radian and sprocket wheel are complementary, and the carrier bar arc radius R of selecting according to the sprocket wheel size is 300～600mm.Interior pin link plate bottom by the sprocket wheel edge is coated with adhesive tape 12, and this adhesive tape is made with the rubber that has polyamide skeleton, and adhesive tape 12 usefulness bolts 16 are fixing, and bolt bottom surface and dovetail groove have certain space, and the replacing adhesive tape only need unload bolt and get final product.
Be with metal at axial plane and inlay attached cover 3 near bearing pin 1, edge cover 3 is total two-layer, all tightly be enclosed within on the bearing pin and adopt 42 silicomanganese alloy materials, transfer between two attached covers of edge with regard to the wearing and tearing that make revolution position between the chain link like this, needed in general about 5 years to change once to inlay attached cover, only need lay down nut 9 and packing ring 8 during replacing, take out bearing pin and just can change.Inlay that pin link plate is close at attached cover 3 two ends and dust collar 2 is equipped with at the arm-tie place, between the interior pin link plate and outside the attached cover of edge dust protecting cap 5 is housed also, enter the bearing pin position between the chain link, the service life of extension fixture to prevent dust.
