In the bottom girder of memorial archway main frame, for supporting step from below；It is characterized in that in memorial archway main frame, and adjust in gap
The top of engagement positions, is provided with topping roll dead eye, the topping roll dead eye and installs topping roll；The both sides difference of step
Acted on the column inwall of memorial archway main frame by adjusting gap plate, respectively there is a fixed pan described step both sides,
Tune gap plane of each fixed pan by upright positioning plane and with gradient is constituted；Positioning plane is vertical with memorial archway main frame
Between the inner surface of post have dowel hole, alignment pin through dowel hole and by be embedded in alignment pin end convex copper billet with
Step phase separation；Alignment pin end coordinates with convex copper billet, and convex copper billet end plane is in close contact with step；It is fixed
Position pin is fixed by clamp nut, and the clamp nut is attached fastening by bolt and memorial archway main frame；
The memorial archway also includes dismounting roll device, and dismounting roll device includes memorial archway bearing, dismounting roll hydraulic cylinder, base
And support base, described dismounting roll hydraulic cylinder one end is fixed on base, and the other end is connected with the right side of memorial archway main frame；It is described
Base two ends are connected with support base, and the memorial archway bearing is arranged on the lower right corner of memorial archway main body, the center of circle and the support of memorial archway bearing
The upper end of seat is in same level.
Compared with prior art, the invention has the beneficial effects as follows：
1) present invention is opened in memorial archway main frame and install in a topping roll dead eye, topping roll dead eye topping roll, this
Sample just eliminates top chock and a lash adjusting device than existing mill housing (application number 2016102045294), so as to
Line of tension is further shorten, overall rigidity is drastically increased.
2) additionally, the present invention realizes putting automatically to memorial archway using dismounting roll hydraulic cylinder by the rotation of memorial archway bearing
, easy disassembly roll, reduces the labour intensity of workman.
3) axially position to step is realized using a pair of alignment pin, simple structure, axially position accurately, is easy to
Dismounting, and as a result of vertically oriented groove, on longitudinal direction and the horizontal gap that disappears, adjusts gap action without impact.
4) the horizontal clearance between step and memorial archway main frame adjusts gap wedge to be engaged to carry out by two, so as to
The gap that accurately, reliably laterally disappears can be realized with simple structure.
