Description
Technical field
The utility model relates to the field, auxiliary equipment place of milling train, relates in particular to a kind of changing rig of milling train.
Background technology
Today, in using industrial equipment, especially use in the production process of milling train, after the roll in the milling train used a period of time, its surface can be worn, and causes rolling steel band Quality Down, so need periodic replacement.Usually changing roll is to be undertaken by manual operation, but manual operation not only easily makes mistakes in Renewal process, and operating personnel's personal safety is difficult to be protected, and take the production time too much, to change efficient low.So, engendered special-purpose roll changing carriage in the production, change roll with the method that mechanization degree is higher, increase work efficiency, reduce dangerous.
Only have one group of changing track for roll on the roll changing carriage commonly used, concerning four-high mill or six-high cluster mill, although existing roll changing carriage can satisfy operation roll of mill and intermediate calender rolls roll change, also have the following disadvantages:
1, when two working rolls of four-high mill need to simultaneously and be changed separately, when perhaps two of six-high cluster mill working rolls and two middle groups need to change simultaneously and separately, except original two changing track for rolls are set, one or more transition brackets also must be set in the roll changing carriage place roll, make troubles for the replacing roll;
2, when many groups roll of milling train need to be changed simultaneously, also between the drag hook dolly of roll, manually add cushion block, can realize that just upper working rolls and lower working rolls changes together, the inconvenience that operates, and also danger coefficient is high.
The utility model content
Technical problem to be solved in the utility model is, a kind of multilayer rail roll changing carriage is provided, and solved when existing roll changing carriage is changed roll transition bracket need to be set, operation inconvenience, the problems such as danger coefficient height.
In order to address the above problem, the utility model provides a kind of multilayer rail roll changing carriage, comprises support, it is characterized in that, also comprises bolt and a plurality of roll change assembly, and bolt is evenly arranged in frame bottom, and affixed with frame bottom, and the roll change inter-module is that stack is arranged; The roll change assembly of the bottom comprises oil cylinder, drag hook, retaining rail, drag hook dolly and roller, and described oil cylinder is fixed on the support; Described drag hook is fixed in oil cylinder one end; Described retaining rail has two, is set in parallel in the drag hook both sides, all is fixed on the support; Described drag hook dolly below is connected with four rolling, and roller all is placed on the retaining rail;
The roll change assembly of other layers comprises oil cylinder, drag hook, retaining rail, movable rail, drag hook dolly and roller,
Described oil cylinder is fixed on the support; Described drag hook is fixed in oil cylinder one end; Described retaining rail has two, is set in parallel in the drag hook both sides, all is fixed on the support; Described drag hook dolly below is connected with four rolling, and roller all is placed on the retaining rail; Described retaining rail is provided with two sections movable rails, and corresponding two spanners with it; The length of movable rail is greater than the diameter of roller; Spanner is fixed on the frame, by the switching spanner, can with movable rail from retaining rail on same straight line, angle of switching is so that have the hole of a bit of movable rail length between retaining rail.The purpose that movable rail is set is to be convenient to roll is hung in or hangs out from non-top layer roll change assembly.
In the time of need to changing roll to milling train, its job step is as follows:
1, multilayer rail roll changing carriage is winched to or is with driving walk to by the frame, so that every layer roller groove retaining rail is all corresponding with working roll and place, intermediate calender rolls position on the frame;
2, start oil cylinder, drag hook is pulled out the old roll in the frame, subsequently old roll is removed, and is transferred to next process;
3, new roll is moved on the support, and keep the retaining rail of every layer of roll change assembly all corresponding with the place, position of frame topping roll;
4, start oil cylinder, successively new roll is pushed the relevant position in the frame, finish roll change work.
Further, described bolt is the set bolt with lowering or hoisting gear.The adjusting pole height is beneficial to retaining rail and aims at the interior track (being practically applicable to the narrower situation of factory building width dimensions) of rolling-mill housing when being used for installing.
Further, described oil cylinder is the twin-stage oil cylinder.Its effect is to shorten cylinder body length (being practically applicable to the narrower situation of factory building width dimensions).
Further, comprise three layers of roll change assembly.
Further, the roll changing carriage support drives for electricity or liquid driving walking (being practically applicable to the rich situation of factory building width dimensions).
No matter the utility model has the advantage of, need not to arrange separately transition bracket, be to change individual layer roll or multilayer roll, and all the energy fast operating is simple and easy to usefulness, effectively reduces the danger coefficient of roll change work, and is applicable to multiple milling train.
