Description
Technical field
The utility model relates to the tank and gating system that is used for the roll body roll change, relates in particular to roll body heavy duty tank and gating system.
Background technology
On the cold rolling mill unit, when backing roll accumulative total reaches certain amount of rolling, need carry out integral replacing to backing roll up and down.
When traditional backing roll is changed, lifting mode to backing roll is as described below: referring to Fig. 1, earlier lower support roller 26 is shifted out frame, in advance two suspender belt 25 middle parts are suspended on the crane ears suspension hook 27, operating personnel hold in the hole 29 of latch insertion lower support roll bearing seat 28 to the basement both hands.Because basement ground is moist and rather dark, therefore generally, operating personnel to lower support roller 26 behaviour, pass both sides totally four latches install and need about five minutes.Subsequently, ears suspension hook 27 slowly descends and stops at lower support roller 26 tops, at this moment needs two groups of operating personnel to basement, respectively lower support roller 26 behaviour, biography both sides suspender belt is effectively entangled firm at bearing pin, and notify the ground control personnel, commander's hoisting machinery limit, limit is observed lower support roller 26 and is slowly risen.
Similarly, when the upper support roller was changed, its process was as described below: with new lower support roller return hang put in place after, a support is hung on the lower support roll bearing seat, drive frame then into the upper support roller shifted out.Afterwards, operating personnel must could hold up bearing pin in the hole that slowly inserts on the bearing block by ladder, after in four whole patchholes of bearing pin, crampon descends, operating personnel must be incorporated into the suspender belt head on the bearing pin by the extension bar of band hook, thereby finish the lifting of upper support roller are changed.
Above-mentioned traditional backing roll is changed operation, and there are the following problems in actual use:
1) in changing operation, operating personnel's basement of will frequently coming in and going out, basement ground humidity, rather dark, and in changing operation, also to carry out work such as bolt axle and cover suspender belt by ladder, pull pin axle and dismounting suspender belt head of whole wiping need spend 25 minutes, so labor intensity of operating personnel is bigger; Simultaneously in changing operation process, operating personnel are in to face the limit operation, and operating personnel's personal safety is caused a hidden trouble.
2) suspender belt is when the lifting backing roll, because supporting roller bearing seat broad, suspender belt is when the lifting backing roll, suspender belt can rub mutually with supporting roller bearing seat pad plate, in order to ensure Current Collector Sleave safety, so must change in per substantially season of suspender belt, about 70,000 yuan of every width of cloth suspender belt price, maintenance cost is higher.
3) when the handling backing roll, because suspender belt is longer, when lifting backing roll roll body, dancing can take place in roll body often, and particularly when handling upper support roller, the swing of roll body can cause support to rock, and makes the replacing operation have major safety risks.For this reason, can only rise slowly repeatedly and put the handling angle of repeatedly confirming suspender belt and roll body slowly, about one and a half hours of therefore each roll body lifting required time has increased non-operation downtime to a certain extent, has influenced unit effective operation rate.
