Abstract
The utility model provides a rolling mill quick roller-replacing device which comprises a first horizontal-moving trolley, a second horizontal-moving trolley, a pulling-pushing trolley and a roller-replacing large trolley. The first horizontal-moving trolley, the second horizontal-moving trolley and the pulling-pushing trolley are placed on the roller-replacing large trolley. The first horizontal-moving trolley and the second horizontal-moving trolley are fixedly connected side by side. The first horizontal-moving trolley and the second horizontal-moving trolley are respectively provided with four roller-replacing tracks. The rolling mill quick roller-replacing device has the advantages that each horizontal-moving trolley is of a double-trolley-position-four-layer-track-left-and-right-horizontal-moving structure, a new working roller, a new middle roller, a replaced working roller and a replaced middle roller can be placed at the same time, the device can achieve simultaneous replacing of the working roller and the middle roller, roller-replacing working can be completed in 5-6 minutes, time is saved by about 10-30 minutes compared with roller replacing in an old-type mode, and rolling mill effective working time is prolonged.
Description
Technical field
The utility model belongs to steel rolling field, especially relates to milling train Quick roll-changing device.
Background technology
Modern six-roll cold mill is very high to rolling rear surface quality requirement, and working roll and intermediate calender rolls roll change are frequent, and 2-3 hour needs are changed once, and change jobs time of roller of old-fashioned roll change mechanism is 15 minutes, and the time of changing intermediate calender rolls is 30 minutes.How to shorten roll changing time, improve operating rate of rolling mill, it is the problem that each cold rolling mill is paid close attention to that performance mill capacity reduces costs.
Summary of the invention
Problem to be solved in the utility model is to provide milling train Quick roll-changing device, is especially applicable to six-high cluster mill and changes working roll and intermediate calender rolls simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Milling train Quick roll-changing device, comprises the first travelling platform, the second travelling platform, push-and-pull vehicle and roll change cart, and described the first travelling platform, described the second travelling platform and described push-and-pull vehicle are positioned on described roll change cart; Described the first travelling platform is connected side by side with described the second travelling platform is fixing; On described the first travelling platform and described the second travelling platform, be respectively arranged with four changing track for rolls.
Further, on described push-and-pull vehicle, be provided with hydraulic pressure hook;
Further, on described roll change cart, be provided with retaining mechanism;
Further, described four changing track for rolls are respectively intermediate calender rolls track, top working roll track, bottom working roll track and lower intermediate calender rolls track, vertically distribute successively.
Further, described the first travelling platform and described the second travelling platform are realized traversing by Driven by Hydraulic Cylinder, and described push-and-pull vehicle drives walking by motor, and described roll change cart is driven by motor, realize and enter and exit.
Further, described hydraulic pressure is linked up with by Driven by Hydraulic Cylinder,
Advantage and the good effect that the utlity model has are: the travelling platform of this milling train Quick roll-changing device adopts two parking stalls, four layers of track, transverse moving left and right structure, can place new working roll and intermediate calender rolls and the working roll changing and intermediate calender rolls simultaneously; This device can realize working roll and intermediate calender rolls is changed simultaneously, and roll change work can complete in 5-6 minute, than old-fashioned roll changing time, saves about 10-30 minute, has improved milling train effective operation time.

The specific embodiment
As shown in Figure 1 and Figure 2, the utility model relates to milling train Quick roll-changing device, comprise the first travelling platform 1, the second travelling platform 2, push-and-pull vehicle 3 and roll change cart 4, described the first travelling platform 1, described the second travelling platform 2 and described push-and-pull vehicle 3 are positioned on described roll change cart 4; Described the first travelling platform 1 is fixed and is connected side by side with described the second travelling platform 2; On described the first travelling platform 1 and described the second travelling platform 2, be respectively arranged with four changing track for rolls.
Further, on described push-and-pull vehicle 3, be provided with hydraulic pressure hook.
Further, on described roll change cart 4, be provided with retaining mechanism.
Further, described four changing track for rolls are respectively intermediate calender rolls track 5, top working roll track 6, bottom working roll track 7 and lower intermediate calender rolls track 8, vertically distribute successively.
Further, described the first travelling platform 1 and described the second travelling platform 2 are realized traversing by Driven by Hydraulic Cylinder, and described push-and-pull vehicle 3 drives walking by motor, and described roll change cart 4 is driven by motor, realize and enter and exit.
Further, described hydraulic pressure hook is by Driven by Hydraulic Cylinder.
The course of work of this example: place in advance new working roll and new intermediate calender rolls on the rod position of the first travelling platform 1, milling train window is aimed in the roll change room of the second travelling platform 2, the retaining mechanism of roll change cart 4 has been inserted in latch on changing track for roll in pin-and-hole, and push-and-pull vehicle 3 advances to the front end of roll change cart 4.
The hydraulic pressure hook of push-and-pull vehicle 3 is caught respectively spindle nose and the hydraulic pressure closure of working roll and intermediate calender rolls; Push-and-pull vehicle 3 is all drawn out to top working roll, bottom working roll and intermediate calender rolls on the second travelling platform 2 simultaneously; Hydraulic cylinder is opened hydraulic pressure hook, and push-and-pull vehicle 3 is withdrawn into the rear end of roll change cart 4; The hydraulic cylinder of the first travelling platform 1 is traversing, and new roller position is traversing to roll change position; Push-and-pull vehicle 3 pushes milling train window working roll and intermediate calender rolls again; The retaining mechanism of roll change cart 4 exits, and roll change cart 4 retreats to deposits position, and so far roll change finishes.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
