The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 5-shown in Figure 7, the utility model provides a kind of top backing up roll bascule of milling train.Wherein milling train includes entablature 11 and memorial archway 12, guide and guard lift cylinder 7 and guide and guard 8 etc., and wherein this top backing up roll bascule comprises parts such as shoulder pole girder 2, compensating cylinder 31, raising rod 5, lifting beam 9 and balance link plate 6.As shown in Figure 5, shoulder pole girder 2 is positioned at entablature 11 tops of milling train.Compensating cylinder comprises cylinder body 301 and the cylinder bar 302 that cooperates with this cylinder body 301, and wherein cylinder body 301 is connected on the milling train entablature 11, and cylinder bar 302 is connected on the shoulder pole girder 2.
In the utility model, as Fig. 5-shown in Figure 15, this top backing up roll bascule also includes clip arrangement 4, this clip arrangement 4 is arranged at entablature 11 tops of milling train, this clip arrangement 4 has the latched position and the position that unlocks of removing the locking of shoulder pole girder 2 of locking shoulder pole girder 2 when roll change and maintenance, thus the definite roll change position that can when roll change and maintenance, keep compensating cylinder and top backing up roll; When the milling train operate as normal, remove locking to shoulder pole girder 2.Like this, owing to can when roll change and maintenance, lock the position of shoulder pole girder 2 by this clip arrangement 4, thereby keep the roll change position, and do not need to keep the roll change position by compensating cylinder, therefore hydraulic cylinder breaks away from the roll change position in the time of can effectively avoiding roll change, the roll change fault of bringing, and avoided equipment and operating personnel's security incident.
As Fig. 8-shown in Figure 15, in the object lesson of clip arrangement 4 of the present utility model, this clip arrangement 4 can comprise clamp 41 and drive the drive unit 42 of this clamp 41, has first fastener at the top of this clamp 41, be provided with second fastener in the bottom of shoulder pole girder 2, this clamp 41 is positioned at the position that first fastener and second fastener stagger, the i.e. position that unlocks of clip arrangement when steel rolling; Roll change and when maintenance by described drive unit 42 drive that clamps 41 move to first fastener position corresponding with second fastener, i.e. the latched position of clip arrangement, thus lock the position of shoulder pole girder.
This drive unit 42 can be specially driving cylinder.This driving cylinder can be specially hydraulic cylinder or pneumatic linear actuator.Certainly, this drive unit 42 also can be other machinery or Vidacare corp, moves between position that first fastener and second fastener stagger and correspondence position as long as can drive clamp.
As Fig. 8-shown in Figure 15, described clip arrangement 4 also includes the guide rail 43 that guiding clamp 41 moves, this guide rail 43 is arranged at the top of entablature 11, thereby guiding clamp 41 moves between between position that first fastener and second fastener stagger and the correspondence position.In roll change and when maintenance, clamp 41 is shifted onto under second fastener of shoulder pole girder 2 according to the step preface that roll change requires, then top roll system is fallen on the clamp 41, keeping stable position, and provide reliable machine security guarantee.
As Fig. 8-shown in Figure 11, in an optional example, the bottom surface of shoulder pole girder 2 can form described second fastener; The last end face of clamp 41 forms described first fastener.This clamp 41 is positioned at outside the shoulder pole girder 2 when steel rolling, roll change and when maintenance by described drive unit 42 drive that clamps 41 move to shoulder pole girder 2 below, thereby lock the position of shoulder pole girder 2.
As Figure 12-shown in Figure 13, in another optional example, described shoulder pole girder 2 bottoms can be provided with backing plate 21, form described second fastener by the bottom surface of this backing plate 21.In this example, because the setting of backing plate 21, the height of this clamp 41 shortens the extreme lower position (as shown in figure 12) that becomes to be lower than shoulder pole girder 2, the original holding fix of clamp 41 can be moved to the center line of shoulder pole girder 2 like this, be hidden under the shoulder pole girder 2, shorten the stroke of drive unit of clamp 41 and the length of clamp guide rail 43, reduced equipment occupation space.
As Figure 14-shown in Figure 15, in another optional example, described clamp 41 can comprise clamp body 411 and be arranged at the movable cushion block more than one 412 on the clamp body 411 that the end face of described movable cushion block 412 forms described first fastener.Figure 14 shows the example that a movable cushion block 412 is set, and it will be understood by those skilled in the art that can be as required, also can be provided with the movable cushion block that stacks together 412 more than two on the clamp body, is not described in detail in this.Like this, it is split type that clamp 41 will be arranged to, and movable cushion block 412 be regulated or be changed to the height of its clamp body 411 can according to on-the-spot actual needs after shortening; Also be convenient to carry out modularized design, be about to clamp body 411 and carry out standardized designs, according to the difference of milling train specification, design different movable cushion block 412 respectively, can reduce the design cycle, lower design difficulty, also be convenient to produce and adopt stable, ripe process for machining and manufacturing, save processing cost.
As Fig. 8, shown in Figure 9, in a specific embodiment of this clip arrangement 4, clamp 41 and drive unit 42 can be positioned at the same side of shoulder pole girder 2 outside clamp 41 is positioned at shoulder pole girder 2 time.Like this, when milling train carries out steel rolling production, the cylinder bar withdrawal of the driving cylinder of drive unit 42, clamp 41 is in shoulder pole girder 2 outsides; When roll change and maintenance, the cylinder bar of this driving cylinder stretches out, and clamp 41 moves to the position of shoulder pole girder 2 belows with locking shoulder pole girder 2, thereby effectively keeps the roll change position.
As Figure 10, shown in Figure 11, in another specific embodiment of this clip arrangement 4, clamp 41 and drive unit 42 lay respectively at the both sides of shoulder pole girder 2 outside clamp 41 is positioned at shoulder pole girder 2 time.Like this, when milling train carries out steel rolling and produces, stretch out as the cylinder bar of the driving cylinder of drive unit 42, clamp 41 is located at the outside of shoulder pole girder 2; When roll change and maintenance, the cylinder bar withdrawal of driving cylinder, clamp 41 moves to shoulder pole girder 2 belows, with the position of locking shoulder pole girder 2, thereby effectively keeps the roll change position.
Foregoing description of the present utility model only is exemplary attribute, and the various distortion that therefore do not depart from the utility model main idea ought to be within scope of the present utility model.These distortion should not be regarded as departing from spirit and scope of the present utility model.
