Abstract
The utility model relates to a blooming mill bearing special lifting device comprises platform sling, jib, is equipped with the three davit that outwards stretches out along the peripheral equidistance of circular platform sling, and a platform sling center rigid coupling head portion ann has the jib of rings. The utility model discloses can fundamentally solve the dismouting and the regular cleaning and the change problem of large-scale rolling mill roll neck bearing and axle sleeve, for the production is in the same direction as the way and is provided reliable guarantee, spare bearing more than 3 reducible sets of every year practices thrift spare part expense 84 ten thousand yuan. Just the utility model discloses simple structure, easy preparation uses safe and reliable, and is nimble convenient, need not maintain and maintain, when improving the rolling mill operating rate, has reduced operating personnel's intensity of labour.
Description
Technical field
The utility model belongs to the steel rolling accessory appliances, and particularly a kind of being specifically designed to hung the suspender that changes blooming mill bearing and bearing carrier ring.
Background technology
For relatively large mill such as heavy steel rolling mill or rough rolling mills, its milling train roll neck adopts bearing lubrication system more, yet because this type of rolling mill bearing size is bigger, weight is more heavy, under the situation that does not have special-purpose bearing and axle sleeve suspender, be to carry out the replacing of bearing and axle sleeve and periodical maintenance cleans, have to keep on the go reluctantly for a long time, the rolling mill bearing that has even reach 6 years because of not cleaning forced service.Therefore, also idol has because of bearing grinds the accident generation of shutting down repair and replacement in the operation of rolling, will cause heavy losses to production in case this situation occurs.Simultaneously, in order to reduce causality loss, each heavy steel rolling mill man has all prepared 3-5 cover bearing in advance in order to standby, the expense of every cover bearing is up to more than 280,000 yuan, therefore every year only replacement bearing just need take 840,000 yuan to 1,400,000 yuan of production circulating fundss, had a strong impact on the turnover and the use of circulating funds.
Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, and a kind of simple in structure, the safe and practical large-sized rolling mills bearing and the special hanger of axle sleeve are provided.
A kind of blooming mill bearing special hanger is made up of hanging scaffold, suspension rod, and along peripheral equidistant three the outwardly directed arms that are provided with of circular hanging scaffold, the affixed head in hanging scaffold center is equipped with the suspension rod of suspension ring.
The suspender that drift bolt is not established in above-mentioned arm end is that hanging scaffold and arm are a flat board, is specifically designed to and hangs the special hanger that changes single row ball bearing.In addition, also can be designed to the arm end and the drift bolt hole is set and be inserted with drift bolt, to change rolling mill bearing used as hanging.
Hanging scaffold and suspension rod can adopt welding, also can establish the hole on hanging scaffold, use the fastening mode of bolt and nut to connect.Hanging scaffold and arm then adopt 20～40mm plate iron to process.
Implement the utility model, can fundamentally solve the dismounting of large-sized rolling mills roll neck bearings and axle sleeve and cleaning and replacing problem regularly, the phenomenon of having avoided bearing to grind, for the direct motion of producing provides the failure-free guarantee, and can reduce the above replacement bearing of 3 covers every year, thereby save 840,000 yuan of spare part expenses.And the utility model is simple in structure, makes easily, and is safe and reliable, flexible, do not need care and maintenance, when improving operating rate of rolling mill, reduced labor intensity of operating personnel on the contrary.
Description of drawings
Fig. 1 is the blooming mill bearing special hanger scheme drawing that has drift bolt.
Fig. 2 is the birds-eye view of Fig. 1.
Among the figure: 1 is that hanging scaffold, 2 is arm, and 3 is drift bolt, and 4 is suspension rod, and 5 is suspension ring.
The specific embodiment
As seen from Figure 1, the utility model mainly is made up of hanging scaffold 1, drift bolt 3 and suspension rod 4.Hanging scaffold 1 is a dull and stereotyped disk, be provided with three outwardly directed arms 2 with hanging scaffold 1 one and along circular hanging scaffold 1 periphery equidistant (being that each differs 120 °), arm 2 ends have the drift bolt hole of laying drift bolt, in the drift bolt hole by drift bolt 3 is arranged, a suspension rod 4 is fixed with nut in the center of circle of hanging scaffold 1, upper end at suspension rod 4 is welded with suspension ring 5, in order to hanging hook.
As seen from Figure 2, drift bolt 3 is the screwed screw mandrels in a bottom, and lower thread can directly be screwed in the fixing threaded hole of bearing carrier ring, by 3 connections bearing carrier ring is stablized more and be sling securely.If uneasy drift bolt on the arm 2, then hanging scaffold 1 is a flat board with arm 2, can be used as and hangs the special hanger that changes single row ball bearing.
Hanging scaffold 1 and arm 2 all adopt the 30mm plate iron to process; Drift bolt 3 is selected the M10 bolt for use, and 4 on suspension rod uses the M60 bolt, and circular suspension ring 5 get final product on its welded top.
Claims (4)
1, a kind of blooming mill bearing special hanger is characterized in that, is made up of hanging scaffold, suspension rod, and along peripheral equidistant three the outwardly directed arms that are provided with of circular hanging scaffold, the affixed head in hanging scaffold center is equipped with the suspension rod of suspension ring.
2, blooming mill bearing special hanger according to claim 1 is characterized in that, described arm end is provided with the drift bolt hole.
