Abstract
The present invention provides a device which is used for replacing a supporting roller part (1) of the transmission guide (2) of a curved continuous casting machine for liquid metal, especially for liquid steel. The device is provided with a rail guiding object (3), wherein the supporting roller part (1) is changed on a changing chain (5) with a mode of being suspended on a hoisting machine (4). Through a static support improved by reducing the weight, the device can be configured in the geometrical shape (10) of the changed rail with the mode that each supporting roller part (1) is arranged with only one replacing wheelset on the frame (1a) of supporting roller part and the last and lowest chain element (5b) in the changing chain (5) of the supporting roller part is arranged with circular arc (2a) of a pair of rail guiding object (3) in a guiding wheel (7) adapted to the space length of shaft.
Description
The present invention relates to a kind of device of supporting roller segment of transmission guide way of the circular-arc type continuous casting machine that is used to change liquid metals, especially liquid steel, have a formation from each supporting roller segment in the place of operation of transmission guide way by the rail-guided body of a circular arc up to the replacing path of continuous casting platform, in its paired track, make supporting roller segment one by one, be suspended on and dismantle swivel bearing on the replacing chain that rises or descend by crane and on the wheel of the replacing on the supporting roller segment or after maintenance, install again.
By EP 1 506 066 B1 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 for a big load left side and right corner to be used to hold the vertical force component of roller section weight of 60t of going directly.
The objective of the invention is, bear the corresponding higher steering force of generation and the cross force that in the supporting roller segment upper side, produces by the geometry of replacing track and by the weight of dismounting chain, reduce the supply of material weight of supporting roller segment simultaneously, thus with more favourable power distribution cost saving.
Above-mentioned purpose is achieved thus according to the present invention, and each supporting roller segment is changed wheel set and supporting roller segment and changed in the directive wheel that last, the nethermost chain link of chain adapting to distance between axles and be furnished with pair of tracks guide way circular arc only being provided with one on the supporting roller segment framework.Advantage is to alleviate supply of material weight (and for the main supply of material and additional replacing section) for supporting roller segment with several tons in conticaster, littler cross force and save otherwise common supporting roller segment is changed the safety pin on the chain in the upper side of supporting roller segment, it prevents that last connecting plate from changeing.
Changing the bottom that wheel set is arranged on supporting roller segment described in the expansion structure, but about 100 to 120mm are higher than common structure.
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 track geometry shape arbitrarily, the distance between axles last, nethermost chain link and each the replacing track geometry shape 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 track geometry shape,
Fig. 2 illustrates the more front view of changing device, the supporting roller segment that has crane, supporting roller segment replacing chain, replacing track geometry shape and will betransported.
The supporting roller segment 1 that from transmission guide way 2, in dismounting or installation process, will be replaced shown in Figure 1.Each supporting roller segment 1 is attached to the circular arc 2a of a rail-guided body.The path vertically directs into the continuous casting platform to circular arc 2a from the place of operation of each supporting roller segment and the rail-guided body 3 of track 3a and 3b constitutes by having at interval as changing in the trend that continues.Making each supporting roller segment 1 change chain 5 by supporting roller segment in each rail-guided body 3 is suspended on the crane 4.This supporting roller segment 1 itself is guided in track 3a and 3b by two this replacing wheel sets 6 at present.Because the present invention saves present going up for weight reduction and changes wheel set, in Fig. 1, on supporting roller segment framework 1a, only exist one to change wheel set 6.Supporting roller segment 1 is also changed chain 5 by supporting roller segment and is suspended on the crane 4 and moves forwards or backwards in order to dismantle and to install.
Particularity of the present invention is, the supporting roller segment 1 of each is changed wheel set 6 and supporting roller segment and changed the circular arc 2a that is furnished with pair of tracks guide way 3 in last, the directive wheel 7 of nethermost chain link 5b in adaptive spacing of chain 5 only having one on the supporting roller segment framework 1a.Realize the particularly advantageous supporting of several tons heavy supporting roller segment 1 thus.Make on the one hand supporting roller segment 1 be bearing in track 3a and 3b the inside, last on the other hand, nethermost supporting roller segment is changed static state that chain chain link 5b bears other constant load component really.But this load component is distributed on directive wheel 7 and the wheel last, nethermost supporting roller segment replacing chain chain link 5a.The suitability of supporting force for example realizes like this according to experience, make and change the bottom that wheel set 6 is arranged on supporting roller segment framework 1a, but about 100-120mm is higher than common (known) structure.Be formed in the supporting of the other end on the throughput direction of supporting roller segment 1 like this, make guiding wheel set 7 and supporting roller segment change the distance between axles last, nethermost chain link 5b of chain 5 much smaller than the distance between axles 9 between two other supporting roller segments replacing chain 5a.Can make supporting roller segment change last, the nethermost chain link 5b of chain 5 according to the replacing track geometry shape 10 (curvature of different circular arc 2a) of rail-guided body 3 as empirical value and be about 50% of the 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.
Can make the distance between axles last, nethermost chain link 5b 8 of directive wheel secondary 7 and supporting roller segment replacing chain 5 change track geometry shape 10 according to the position (arrow in left side is represented in only by Fig. 1) of supporting roller segment 1 in the circular arc of transmission guide way 2 coordinates mutually with each.
