Background technology
Guide and guard just refer to during rolling of sectional iron, rolled piece are helped to press set direction and shape before and after roll pass
State accurately, the device of steadily into and out roll pass, guide and guard have the following advantages：1st, iron scale can be removed；
2nd, rolled piece surface can be made more smooth；3rd, rolled piece surface strength can be increased；4th, make rolling process safer, more stable.
Roughing mill guide and guard case is mounted in the middle part of the memorial archway of roughing mill.The entrance of roughing mill is respectively equipped with a set of.It is main
Effect is that slab is imported milling train, and milling train is made to realize smoothly rolling.Guide and guard case in rolling process in company on upper roller similarly hereinafter
When act.Guide and guard case is linked together by the transmission device of guide and guard sunpender and axis pin and top.When replacing working roll, guide and guard
Transmission device above case operates the height and position to adjust guide and guard case, so as to fulfill roll change operation.
But due to roughing mill in the operation of rolling strip be frequently found button nose phenomenon, when strip nose its
Head will hit guide and guard lower box part, and guide and guard case is caused to be lifted upwards, and guide and guard case again jacks up sunpender upwards, and such sunpender will
The ground jack of the guide and guard transmission device of top and gear-box top is bad, the disorderly closedown of equipment is caused, is seriously affecting rolling line just
Often production.
Utility model content
In order to overcome the shortcomings of the prior art, guide and guard transmission dress after existing guide and guard case is hit by the strip of nose is solved
Flimsy technical problem is put, the utility model provides a kind of guide and guard automatic lifting regulating device.
The utility model is achieved by the following technical programs：
A kind of guide and guard automatic lifting regulating device, it includes guide and guard case, guide and guard case transmission device and for connecting guide and guard
The guide and guard sunpender of case and guide and guard case transmission device, guide and guard case transmission device by guide and guard sunpender drive guide and guard case vertically on
Lower reciprocating motion, wherein：The top of guide and guard sunpender is provided with through-hole, and the lower end of guide and guard sunpender is provided with waist-shaped hole, through-hole with
The power output end connection of guide and guard case transmission device, the guide and guard upper box part are provided with lifting lug, spacer pin are equipped on lifting lug, limit
Position pin slides in the waist-shaped hole.
Further, the through-hole and waist-shaped hole are connect with the surface of guide and guard sunpender by chamfered transition.
Further, a diameter of 60mm of waist-shaped hole both ends circular arc, the length of the centre-to-centre spacing of waist-shaped hole both ends circular arc
For 50mm.
The utility model has the advantages that compared with prior art：
Using the present invention it is possible to prevente effectively from guide and guard case is by after the strip shock of nose, guide and guard case jacks up cause guide and guard upwards
The ground jack of transmission device, gear-box are jacked up the problem of damaging, and are prevented guide and guard transmission device and are broken down shutdown, can extend
The service life of ground jack, gear-box reduces spare part expense.
The guide and guard apparatus for automatically lifting of the installation present invention has two big benefits：
1st, fault time is saved, it is annual to save number of stoppages 4 times or more, 4 times × 6 hours=24 hours fault time is saved,
It is calculated according to 200 yuan of 410 ton hour of yield, ton steel profits during hot continuous rolling brand-name computer, 24 × 410 × 200=196.8 can be saved every year
Wan Yuan.
2nd, spare part expense expenditure is saved：No. 4 ground jacks, gear-boxes are originally needed to change every year, per annual cost：Ground jack 0.9
0.5 ten thousand × 4 times=5.6 ten thousand yuan of ten thousand+gear-box can extend to every 2 years and replace primary, annual saving spare part expense 5.6 ten thousand now
Member.
Description of the drawings
