Description
The present invention relates to a kind of device of supporting roller segment of the transmission guide way that is used to change liquid metals, especially liquid steel circular-arc type continuous casting machine.
By EP 1506066B1 known in described field this device that is used for supporting roller segment.But this structure will reach higher bearing capacity and use first and second transverse arms for this reason, wherein supports the vertical force component that is used to hold up to the roller section weight of 60t for big a load left side and right corner.
Device by the supporting roller segment of the known transmission guide way that is used to change the liquid metals circular-arc type continuous casting machine of Japanese document JP 62142057.This device has a rail-guided body with paired guide rail, by rail-guided body supporting roller segment is suspended on the supporting roller segment replacing chain one by one and dismantles or take off by crane.Each chain link that supporting roller segment is changed chain has a wheel set respectively, and it is by the paired guide rail guiding of rail-guided body.Make supporting roller segment also have one similarly and change wheel set, supporting roller segment is guided on rail-guided body by it.
The present invention seeks to, change the device of supporting roller segment in known being used for, the high steering force that absorption produces by the geometry of changing guide rail with by the weight of dismounting chain and in the cross force of the upper side region generating of supporting roller segment, reduce the supply of material weight of supporting roller segment simultaneously, thus with the saving of more favourable power distribution realization expense.
Above-mentioned purpose is achieved thus according to the present invention, and last, the nethermost chain link that described supporting roller segment is changed chain is furnished with a guiding wheel set and makes wheel set and the distance between axles between the wheel set of leading adapt to the arch section of rail-guided body at the last chain link that supporting roller segment is changed chain on the wheel set next door that is attached to it.
Advantage is to make the supply of material weight of supporting roller segment reduce several tons (and being on the main replacing section of supplying and adding) in conticaster, have a littler cross force and saved supporting roller segment and changed the safety pin that will adopt usually on the chain in the upper side zone of supporting roller segment, it prevents that rearmost connecting plate from coming back rotation.
The distance between axles last, nethermost chain link that described guiding wheel set and supporting roller segment are changed chain is changed distance between axles between the chain chain link much smaller than two other supporting roller segments, helps to change chain by supporting roller segment thus and bears active force.
Advantageously verified as practical embodiments, change last, the nethermost chain link of chain at supporting roller segment and be about 50% of each mutual distance between axles of all the other supporting roller segments replacing chain chain links with distance between axles between the guiding wheel set.
But also can select to change the guide rail geometry arbitrarily, the distance between axles last, nethermost chain link and each the replacing guide rail geometry that make described guiding wheel set and supporting roller segment change chain are coordinated mutually.
Embodiments of the invention shown in the drawings are described them below in detail.In the accompanying drawing:
Fig. 1 illustrates the side view of conticaster, has trend and supporting roller segment that rolls away from present or sail into of guide rail geometry,
Fig. 2 illustrates the more front view of changing device, the supporting roller segment that has crane, supporting roller segment replacing chain, replacing guide rail geometry and will betransported.
Figure 1 illustrates the supporting roller segment (backing roll portion section) 1 that from transmission guide way (strand-guiding roller) 2, in dismounting or installation process, will be replaced.Set an arch section 2a of a guide rail mechanism for each supporting roller segment 1.Arch section 2a in continue extending as change the path vertically extend to from the place of operation (work) of each supporting roller segment continuous casting platform and formation have separately guide rail 3a and the rail-guided body (track leader) 3 of 3b (Fig. 2).In each rail-guided body 3, each supporting roller segment 1 utilizes a supporting roller segment to change chain 5 and is suspended on the crane 4.This supporting roller segment 1 itself is to lead in guide rail 3a and 3b by two such replacing wheel sets 6 before this.Owing to the present invention has cancelled the replacing wheel set on the top of using up till now for weight reduction for this reason, therefore in Fig. 1, on supporting roller segment framework 1a, only also there is one and changes wheel set 6.Therefore, in order to dismantle or install supporting roller segment 1, it is suspended on the crane 4 by means of supporting roller segment replacing chain 5 and moves forwards or backwards.
Special feature of the present invention is, each supporting roller segment 1 only is provided with one and changes wheel set 6 and supporting roller segment and change last, the nethermost chain link 5b of chain 5 and be furnished with a pair of directive wheel 7 on supporting roller segment framework 1a, this is suitable with the arch section 2a of rail-guided body 3 on spacing to directive wheel.Realize particularly advantageous supporting thus to several tons heavy supporting roller segment 1.On the one hand, supporting roller segment 1 is bearing in guide rail 3a and 3b the inside, and on the other hand, wheel last, nethermost supporting roller segment replacing chain chain link 5b is born other the definite load part of static state.But this load part will be assigned on directive wheel 7 and the wheel last, nethermost supporting roller segment replacing chain chain link 5a.According to empirical value, the coupling of supporting force for example realizes like this, and replacing wheel set 6 is arranged in the lower area of supporting roller segment framework 1a, but than the common high approximately 100-120mm of (known) structure.The other end at the throughput direction upper support of supporting roller segment 1 is designed in this wise, makes distance between axles last, nethermost chain link 5b that guiding wheel set 7 and supporting roller segment change chain 5 much smaller than the distance between axles 9 between two other supporting roller segment replacing chain 5a.Can make supporting roller segment change last, the nethermost chain link 5b of chain 5 according to the different situations (the different curvature of arch section 2a) of the replacing guide rail geometry 10 of rail-guided body 3 as empirical value and be about 50% of each mutual distance between axles 9 of all the other supporting roller segments replacing chain chain link 5a with distance between axles 8 between the guiding wheel set 7.
According to the position of supporting roller segment 1 in transmission guide way 2 arch section of (arrow in left side is represented in only by Fig. 1), the distance between axles last, nethermost chain link 5b 8 that can make directive wheel secondary 7 and supporting roller segment change chain 5 is changed guide rail geometry 10 and is coordinated mutually with each.
