Abstract
The utility model discloses a kind of pig machine carrier bar, this carrier bar two ends semicircular in shape, one end is monaural, the other end is ears, and its two ends endoporus is all inlayed wear-resistant sleeve, is characterized in, on this carrier bar, plane and lower plane are symmetrical tread, and carrier bar middle part is provided with laterally zygomorphic support ear.Because plane on this carrier bar and lower plane are symmetrical tread, middle part is provided with the support ear that connects pig mold of pig machine, thus carrier bar without levoform carrier bar and right formula carrier bar minute, highly versatile, can conveniently realize modularization and produce.Carrier bar in use, when the larger tread wear extent of carrying reaches capacity, chain band continue to be used after can realizing 180 ° of upsets, effectively overcome existing carrier bar in use can not overturn 180 ° realize exchange, asymmetric, the defect such as the life-span is short of wearing and tearing, be 2～3 times of existing carrier bar the service life of this carrier bar, pig machine user's buying and maintenance cost can be significantly reduced, the normal operation of pig machine can be guaranteed preferably.
Description
Technical field
The utility model relates to the supporting long-life carrier bar of the supporting driving member that a kind of blast furnace pig machine is used, particularly a kind of pig machine.
Background technology
Pig machine, for the molten iron direct casting of blast furnace or non-blast furnace ironmaking technique output being become to the equipment of iron block, is being brought into play very important effect in integrated iron and steel works particularly smelt iron enterprise's production.
At present, pig machine that most iron and steel enterprise is used generally all adopts the transmission of the fixed chain band of running roller, and carrier bar is crux driving member wherein.Carrier bar two ends are semicircle otic placode, and one end is monaural, and the other end is ears, and the set endoporus in two ends is all inlaid with high-quality steel wear-resistant sleeve, use power transmission shaft and the hinged composition driving-chain of hollow shaft band between each carrier bar.During chain tape running, two treads of carrier bar contact and form rolling friction with upper and lower layer running roller respectively, when particularly chain tape running is to upper strata, owing to filling with molten iron in casting iron mould, the load that both sides carrier bar bears is larger, thus under carrier bar the wearing and tearing of tread to go up tread especially serious.When the wear extent of tread reaches capacity instantly, will cause carrier bar to scrap too early, in addition now with carrier bar, divide levoform carrier bar and right formula carrier bar, chain band continues to use after can not realizing 180 ° of upsets.Therefore, the service life of carrier bar is shorter, when user more renews carrier bar, very wastes time and energy again, and maintenance and use cost is also higher.In addition, the generalization degree of existing carrier bar is lower, and the production cycle is long, and manufacturing cost is high, can not realize modularization and produce.
Utility model patent ZL 200620151868.2 discloses a kind of chain belt of pig machine, solved when pouring molten iron, because splashing, molten iron causes remaining molten iron between carrier bar, after cooling, make between carrier bar because the molten iron solidifying clings the problem that can not rotate, but can't solve the problems referred to above that current pig machine carrier bar in use exists.
For this reason, market urgently provides that a kind of generalization degree is higher, is convenient to realize modularization manufacture regardless of left carrier bar and right formula carrier bar, the pig machine carrier bar of long service life.
Summary of the invention
The problems referred to above that the utility model exists for solving existing cylinder iron chain plate, provide a kind of cast iron chain plate, and it is regardless of levoform carrier bar and right formula carrier bar, generalization degree is higher, be convenient to realize modularization manufacture, it is convenient in use procedure, to change, maintenance and use cost.
The technical solution adopted in the utility model:
This pig machine carrier bar two ends semicircular in shape, one end is monaural, and the other end is ears, and the otic placode endoporus of monaural and ears is all inlayed wear-resistant sleeve, and on this carrier bar, plane and lower plane are symmetrical tread, the upper and lower support ear at carrier bar middle part is symmetric support ear.
Described carrier bar adopts high-strength cast steel to make.Carrier bar two ends otic placode endoporus is all inlayed high-quality steel wear-resistant sleeve.
By power transmission shaft and hollow shaft, single, double ear is hinged between described carrier bar, form driving-chain band.
Described support ear is connected and fixed the pig mold of described chain band and pig machine by securing member.
The beneficial effects of the utility model:
Because plane on this carrier bar and lower plane are symmetrical tread, middle part is provided with the ear of symmetric support up and down that connects pig mold of pig machine, thus carrier bar without levoform carrier bar and right formula carrier bar minute, highly versatile, can conveniently realize modularization and produce.Carrier bar in use, when the larger tread wear extent of carrying is when reach capacity, continues to use after turning 180 ° of chain band.Therefore, can effectively overcome existing carrier bar in use can not overturn 180 ° and realize exchange, short defect of life-span, be 2～3 times of existing carrier bar the service life of this carrier bar, can significantly reduce pig machine user's buying and maintenance cost, can guarantee preferably the normal operation of pig machine.

Fig. 2 is the top view of Fig. 1;
Fig. 3 is the cutaway view of Fig. 1;
Fig. 4 is the installation sketch of pig machine carrier bar;
Fig. 5 is the cutaway view of Fig. 4.
The specific embodiment
Below in conjunction with accompanying drawing, introduce embodiment of the present utility model.
As shown in Figure 1, 2, 3, this pig machine carrier bar 1 adopts high-strength cast steel to make, its two ends semicircular in shape, one end is monaural, the other end is ears, the endoporus of monaural and ears is all inlayed high-quality steel wear-resistant sleeve 2, and carrier bar 1 middle part is symmetrically arranged with two support ears 3 up and down, and carrier bar 1 upper surface and lower surface are symmetrical tread 4.
This novel carrier bar only in operational phase with regard to its residing relative position, have " levoform carrier bar " and " right formula carrier bar " minute, Fig. 2,3 is depicted as " right formula carrier bar ", if upset is " levoform carrier bar " after 180 °.In the design and manufacture stage with regard to itself structure, without levoform carrier bar and right formula carrier bar minute, and no matter existing carrier bar is in the Design and manufacture stage, or operational phase all have levoform carrier bar truly and right formula carrier bar minute, and after 180 ° of levoform carrier bar and the upsets of right formula carrier bar, can not realize exchanging and use.
Shown in Fig. 4,5, this pig machine carrier bar utilizes monaural and ears to be connected respectively its front and back carrier bar 1, and forms driving-chain band by the chain connection with power transmission shaft 7 and hollow shaft 8.Driving-chain band is installed on above the running roller 5 of some, and each running roller 5 is fixed on the long base 6 of running roller of pig machine by connecting bolt.Upper and lower symmetrically arranged two support ears 3 in novel carrier bar middle part, are connected and fixed two ends carrier bar 1 and the pig mold 9 of pig machine by bolt 10.Carrier bar 1 in use, when larger tread 4 wear extenies of carrying are when reach capacity, can be pulled down pig mold 9 very easily, and segmentation continues to use by after 180 ° of chain band upsets.
