Abstract
The utility model relates to an externally mounted rotary joint for a roller at a fan-shaped segment. The externally mounted rotary joint comprises rotary joints, the roller and bearing supports arranged at two ends of the roller, wherein shaft necks at two ends of the roller extend outwards to the outer side of the bearing support; the rotary joints are internally screwed in the shaft necks; and connectors connected water supply pipelines are mounted on the rotary joints. The utility model has the advantages of reducing the requirement for installation accuracy of the rotary joint, facilitating the replacement of the rotary joint and the assembly and adjustment of the roller, prolonging the service life of the rotary joint, greatly saving the cost, reducing the labor intensity and revolutionarily prolonging the service life of the fan-shaped segment.
Description
Technical field
The utility model relates to a kind of fitted outside swivel joint, and is a kind of specifically in the metallurgy industry casting process, in order to improve and to guarantee slab quality and the fitted outside fan-shaped section roller swivel joint that is used to prevent leak.
Background technology
At present, strand after going out crystallizer at first contact be fan-shaped section, therefore to fan-shaped section require high; Particularly fan-shaped section is to the cooling problem of strand; Require the fan-shaped section roller that drainage must not be arranged, but in actual use, swivel joint is bringing into use Shi Buhui phenomenon to occur leaking; Using about a week owing to reasons such as wearing and tearing sealing can cause swivel joint to leak; This swivel joint is that an end is fixed on that the other end is fixed on the roller on the bearing block, therefore is to the processing of whole roller or all high to the matching requirements of whole roller, has a link error to occur slightly and more just is easy to cause swivel joint to leak.The swivel joint both sides leak along the roller side; When swivel joint leaked, water can flow out from the osculum of end in theory, because under the condition of high temperature and constantly wearing and tearing; Oil sealing also plays the effect of water seal simultaneously; Sealing to axle journal will be gapped, and water will outflow below roller, flows to casting billet surface the quality of strand is impacted.Even osculum can be discharged leaking of swivel joint fully, but still will change swivel joint, hang out fan-shaped section, ressemble swivel joint to the roller dismounting, labour intensity is big, and the equipment use cost is high.
The utility model content
The utility model technical problem to be solved is; Overcome the shortcoming of prior art; Propose a kind of efficient, antileaking, overhaul fitted outside fan-shaped section roller swivel joint easily; Can in continuous casting production process, satisfy processing parameter, and guarantee that strand obtains best cooling effect in the process that forms.
In order to solve above technical problem; The utility model provides a kind of fitted outside fan-shaped section roller swivel joint; Comprise swivel joint, roller and be arranged on the bearing block at said roller two ends; The axle journal extension at said rod two ends is threaded onto in the said axle journal in the said swivel joint in the outside of said bearing block.
The change that one end of swivel joint and roller assembling have no; The other end and bearing block junction by former be to be installed in the bearing block fully first; Change to now cooling water channel is arranged on bearing block outside entering swivel joint, so just can avoid fully because of swivel joint leaks, and the problem that causes whole roller to drip; Thereby solved the problem of leaking of fan-shaped section in itself, and then improved the quality of products.
Further, aforementioned fitted outside fan-shaped section roller swivel joint also is equipped with the connector that links to each other with supply channel on said swivel joint, be used for supplying water to swivel joint.
The beneficial effect of the utility model is: (1) has reduced the installation accuracy requirement of swivel joint, has avoided accumulated error.(2) swivel joint is changed conveniently, need not dismantle roller, can on-line replacing, and the service life of having improved fan-shaped section greatly.(3) made things convenient for the assembling and the adjustment of roller, can not damage swivel joint because of the assembling of bearing block and roller.(4) improved swivel joint service life, improved present about 180 days, practiced thrift cost greatly, reduced labour intensity by about 15 days of past, the prolongation of the property changed the service life of fan-shaped section.(5) water route intakes by changing into outside bearing block in the bearing block, has stopped water and has flowed out from the roller limit, also can not influence slab quality even swivel joint leaks, and be easy to spot check.

The specific embodiment
Embodiment 1
A kind of fitted outside fan-shaped section roller swivel joint that present embodiment provides; Structure is as shown in Figure 1; Comprise swivel joint 1, roller 8 and be arranged on the bearing block 7 at said roller two ends; Axle journal 6 extensions at said rod 8 two ends are threaded onto in the said swivel joint 1 in the said axle journal 6 in the outside of said bearing block 7, and the connector 5 that links to each other with supply channel also is housed on said swivel joint.
The utility model adds the axle journal of roller to grow to and exceeds bearing block 7 fully; The change that one end of swivel joint 1 and roller journal 6 assemblings have no; The other end and bearing block 7 junctions by former be to install in bearing block the inside fully first, change to present water route and get into swivel joint 1 in the bearing block outside.So just can avoid leaking of swivel joint 1 fully, thereby solve the problem of leaking of fan-shaped section in itself.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. fitted outside fan-shaped section roller swivel joint; Comprise swivel joint, roller and be arranged on the bearing block at said roller two ends; It is characterized in that: the axle journal extension at said rod two ends is threaded onto in the said axle journal in the said swivel joint in the outside of said bearing block.
2. according to the said fitted outside fan-shaped section of claim 1 roller swivel joint, it is characterized in that: the connector that links to each other with supply channel also is housed on said swivel joint.
