Description
Technical field
The utility model relates to metallurgical cold-rolling mill, and particularly, the utility model relates to a kind of milling train transmission shaft support device.
Background technology
In the later stage nineties, metallurgical five frame tandem rollings all adopt the mode of working roll transmission substantially, being main transmission motor is connected together and is realized transmission, at this moment by gear-box, power transmission shaft and working roll, and the roll change frequency of working roll is higher, and need to change more than 3 times general every day.
Before working roll is extracted frame out, be connected with gear-box with its direct-connected power transmission shaft one end, one end is connected with working roll in addition, if working roll needs and power transmission shaft is thrown off, now power transmission shaft does not support (working roll supports power transmission shaft by adapter sleeve) near working roll one side.For this reason, must design a support, before compressor emergency shutdown roll change, bracing or strutting arrangement action, to support power transmission shaft, guarantees that power transmission shaft and working roll disengagement inter-axle shaft still can keep original state and can not bow.
Existing design is all that upper lower drive shaft is all provided with separately support, more representational two kinds of Design Modes, and a kind of is the design of Mitsubishi Hitachi; the supporting way of lower drive shaft is fixed, during compressor emergency shutdown, and working roll bending cylinder action; under power transmission shaft, drop on fixing bracket; the bracket of top roll is movable, and when normal production, bracket is inner in frame; separated with power transmission shaft; after compressor emergency shutdown, under the effect of hydraulic cylinder, stretch out frame, hold and upload moving axis.
The upper lower support of another mode Ze Shi SMS company design is all movable supporting way.When normal production, the Support bracket of upper working rolls and lower working rolls is separated with power transmission shaft under the effect of hydraulic cylinder, and when roll change, bracket closes up respectively under the effect of hydraulic cylinder separately up and down, supporting shaft.
Yet above-mentioned these two kinds of modes have a common ground,, because working roll is each up and down, to the support of upper working rolls and lower working rolls, be independently, in order to guarantee that bracket puts in place before extracting working roll out, position to all brackets is equipped with phaseswitch, have so up and down 4 brackets, (bracket has two phaseswitch, a position when detecting it and closing up for 8 phaseswitch, a position when detecting it and opening), obviously cause complicated structure.On the other hand, the environment facies in rolling-mill housing are on duty, and hot and humid environment is very large on the life-span impact of phaseswitch, extremely easily break down, in order to reduce fault, these phaseswitch are the product of dependence on import Siemens substantially, price, delivery cycle is long.Simultaneously, because upper lower carriage is separate, the rigidity of whole support is poor, and the problem such as easily deform.
