Description
Technical field
The utility model relates to a kind of rod-toothed crusher compound spider, is used for broken lump ore, is particularly suitable for the crash high temperature sintering deposit, belongs to field of metallurgical machine.
Background technology
General rod-toothed crusher star-wheel can be divided into star-wheel body and the tup two large divisions who is with convex body, is hammerhead jib with the convex body on the star-wheel body, tup is fixed on the convex body of star-wheel body with bolt, constitutes the combined type star-wheel.Star-wheel body and tup form through machining by cast blank.The tup material is the high hardness wear-resisting alloy, and star-wheel body material is a heat-resisting alloy.Because the mating surface of tup and star-wheel body needs machined, so tup should not adopt unmanageable high rigidity heat-resistance abrasion-resistance alloy material.During the fragmentation sintering deposit, under the working environment about 1000 ℃, because of star-wheel body, tup, attachment bolt material difference, expand, shrink also inequality, add the effect of special interruption shock loading, tup is very easily loosening, produces the tup deflection, it is bad to cause tup to be blocked, even burn out the rod-toothed crusher motor, or attachment bolt blocked disconnectedly, falls the tup phenomenon, reduce disintegrating machine efficient, influenced ordinary production.And after tup falls down, can not in time load onto new tup again, the convex body of fixed hammer is just ground off very soon on the star-wheel body, and disintegrating machine was lost efficacy.The star-wheel life-span generally has only about 3 months.For solving the tup problem and improving wearability, the manufacturer production that has a kind of monoblock cast discaling roll, its star-wheel body and tup and crusher shaft are cast as one, the hard, wear-resistant alloy of surface overlaying one deck costliness, and the way of taking axle and tup water flowing to cool off prolongs the life-span of star-wheel.Though this single roll crusher has solved the tup problem, but bring following three new problems: the first costs an arm and a leg; Its two because weld deposit process is mother metal local heating distortion and a process that intensity constantly reduces repeatedly, after built-up welding was repaired 2～3 times, its built-up welding reduced greatly, the integral body of just having to is scrapped renewal, causes the spare part expense to raise; Its three, after the tup serious wear, can drainage take place and influence production, thereby reduced equipment operation rate.
Summary of the invention
The purpose of this utility model provides that a kind of cost is low, the life-span is long, maintenance capacity is little and can effectively improve the compound spider of equipment operation rate.
The purpose of this utility model is achieved in that
The utility model adopts the external form of common star-wheel, be to prolong the life-span of tup itself, and the utility model is cancelled the convex body on the general star-wheel body, star-wheel body and tup and hammerhead jib is made the disjunctor link arm tup of integral type.Earlier make the star-wheel body that has groove, then high hardness wear-resisting material or high rigidity heat-resistant and wear-resistant material are casted in the groove of star-wheel body as the link arm tup with material heat-resisting and that be easy to machining.For increasing the bond strength of link arm tup and star-wheel, the utility model interconnects three hammerhead jib roots with the disjunctor portion of three sections annulars, and together is cast in the annular groove of star-wheel body, constitutes the compound spider of band disjunctor link arm tup.The utility model is the high rigidity heat-resistant and wear-resistant material because of tup and hammerhead jib, so can obstructed water cooling; The compound spider of corresponding size and quantity is installed according to the length of crusher shaft.After the tup wearing and tearing of the present utility model, but the built-up welding reparation; During serious wear, can singlely change.This compound spider had both solved the tup problem, and maintenance capacity is again little, thereby helped improving equipment operation rate, and the wearable hard alloy of not built-up welding costliness, so cost reduces greatly, spare part takes also significantly decline; Because whole disjunctor link arm tup has all adopted the high-abrasive material of high rigidity, its life-span also obviously prolongs.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the front view of the utility model rod-toothed crusher compound spider.
Fig. 2 is the A-A profile among Fig. 1.
Fig. 3 is the external form figure of star-wheel body of the present utility model.
Among the figure: 1-disjunctor link arm tup, 2-star-wheel body, the centre bore of 3-star-wheel body 2 endoporus that cooperates of rod-toothed crusher axle (the star-wheel body 2 with), 4-star-wheel body outer surface groove, the 5-tup, 6-hammerhead jib, 7-annular disjunctor portion, 8-hammerhead jib root, the root of h-disjunctor link arm tup 1 embeds the degree of depth (groove depth of groove 4) in the star-wheel body 2.
The specific embodiment
The utility model compound spider is formed by the star-wheel body 2 of band centre bore and surface groove with star-wheel body 2 casting all-in-one-piece disjunctor link arm tups 1.Have groove 4 on the outer surface of described star-wheel body 2.Described disjunctor link arm tup 1 is made of three tups 5 and hammerhead jib 6, the root 8 of three hammerhead jibs 6 is connected to each other together by three sections annular disjunctor portions 7, and the root 8 of described hammerhead jib 6 and annular disjunctor portion 7 are embedded in by casting in the groove 4 of star-wheel body 2 and with it and become one.Described star-wheel body 2 adopts material casting heat-resisting and that be easy to machining to form, and then the disjunctor link arm tup of being made by high hardness wear-resisting material or high rigidity heat-resistant and wear-resistant material 1 is casted on the groove 4 of star-wheel body, forms compound spider.Described tup 5 and hammerhead jib 6 can be more than three.
The centre bore 3 of described star-wheel body 2 is the circular port of hexagon, all directions shape or band keyway, described compound spider is fixed on the rod-toothed crusher axle by centre bore 3 suits of star-wheel body 2, and the compound spider of corresponding size and quantity is installed according to the length of rod-toothed crusher specifications and models and crusher shaft.
The shape of cross section of the groove 4 of described star-wheel body 2 can be U-shaped or V-arrangement (being usually said dovetail groove).The degree of depth h that the root 8 of disjunctor link arm tup 1 embeds in the star-wheel body 2, the groove depth that also is groove 4 is not less than 25cm, combine firmly with after guaranteeing disjunctor tup 1 and star-wheel body 2 being cast, and enough intensity arranged, concrete numerical value is different different because of the specification of disintegrating machine and the material that adopted, can be determined by test.
The utility model compound spider is compared with star-wheel commonly used, and its advantage is:
1, can not fall tup;
2, because not wear-resisting convex body has been cancelled in the improvement of structure on the star-wheel body 2, whole disjunctor link arm tup 1 all adopts with a kind of high rigidity heat-resistant and wear-resistant material, so overall life can prolong more than 3～4 times.Infer that according to the situation that used 2 months the production scene overall life can reach more than 1 year;
3, under the situation of saving a large amount of spare parts,, help improving equipment operation rate owing to reduced shutdown maintenance and changed the spare part time.Compare with the built-up welding star-wheel, maintenance of this compound spider and replacing conveniently are conspicuous, and that cost reduces is about 1/3rd to 1/2nd, because of not needing the hard, wear-resistant alloy of integral replacing and built-up welding costliness, so also help improving equipment operation rate and reduce the spare part expense.
