Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
A kind of trailing type changing rig, including machine outside track 2, machine inner orbit 3, follow-up connector 5 and servo-actuated roll change buggy 6,
Machine inner orbit 3 is left and right symmetrically arranged in frame, and the end face of machine outside track 2 is fixed on frame side by screw and alignment pin,
Machine outside track 2 is docked with machine inner orbit 3, and roll change bearing 4 is fixed by screws on the bearing block of roll, is added on follow-up connector 5
Work has two hinge holes and a long screwed hole, and the hinge hole on termination passes through hinge on roll change bearing 4, the hinge at middle part
Hole is connect by hinge on servo-actuated roll change buggy 6, the wheel on servo-actuated roll change buggy 6 is fitted in the upper surface of machine inner orbit 3
On, follow-up connector 5 is fixed on the cylinder rod end of roll change oil cylinder 7 by long screwed hole；Roll change oil cylinder 7 is hinged by the hinge in the middle part of it
On cylinder support 8, on the basis of cylinder support 8 is fixed on by foundation bolt.
Cover sheet 1 is stamped on described machine outside track 2.
As shown in figure 1, the piston rod end of roll change oil cylinder 7 is fixedly connected follow-up connector 5, roll change bearing 4 is fixed on roll
On bearing block, follow-up connector 5 is hinged on roll change bearing 4, and each position connection is reliable, realizes reliable in action.Servo-actuated roll change buggy 6
Play a part of to support follow-up connector 5 and roll change oil cylinder 7 when the present invention is in roll change state, make roll change operation convenient and swift；
When roll is in rolling working condition, it is servo-actuated roll change buggy 6 and departs from plane contact with follow-up connector 5, is servo-actuated the weight of roll change buggy 6
Amount is supported by changing track for roll, does not interfere with the normal production of milling train.
Servo-actuated roll change buggy 6 is made up of car body, axletree, wheel, and servo-actuated roll change buggy 6 is passed through by the hinge hole on hanger
Bearing pin is hinged with the hinge hole at the middle part of follow-up connector 5, realizes the lag function of servo-actuated roll change buggy 6.Follow-up connector 5 leads to
Cross screwed hole and be fixed on the piston rod end of roll change oil cylinder 7, be hinged on roll change bearing 4 by the hinge hole of its end, roll change
Seat 4 is fixed by screws on roll chock, and roll change oil cylinder 7 is hinged on cylinder support 8 by the hinge in the middle part of cylinder body.
As shown in Fig. 2 the present invention has two operating positions, and when roll is fallen on changing track for roll, a kind of trailing type roll change
Device is in roll change state, now, is servo-actuated the car body upper surface of roll change buggy 6 and fits with the contact of the lower surface of follow-up connector 5, roll change oil
Cylinder 7 stretches out, and roll is released from frame, and servo-actuated roll change buggy 6 is servo-actuated slave inner orbit 3 and moves to machine outside track 2, roll change oil
When cylinder 7 is fully extended, roll reaches the limit of position, the bearing pin of connection follow-up connector 5 and roll change bearing 4 is extracted, follow-up connector 5
Fall on servo-actuated roll change buggy 6, be now servo-actuated roll change buggy 6 and bear anterior and follow-up connector 5 the weight of roll change oil cylinder 7.To change
Roller oil cylinder 7 is retracted, and is servo-actuated the follow-up motion of roll change buggy 6 to frame, is now servo-actuated roll change buggy 6 and roll change oil cylinder 7 will not
Affect the lifting of roll.The roll of release is hung away, new roller is fallen on machine outside track 2, roll change oil cylinder 7 stretches out, be servo-actuated roll change
The support of dolly 6 follow-up connector 5 and is moved on machine outside track 2, the hinge on the hinge hole alignment roll change bearing 4 on follow-up connector 5
Bearing pin is inserted into hinge hole when connecing hole, now retraction roll change oil cylinder 7 draws in new roller in frame, when roll moves to the position of requirement
Put the action for stopping roll change oil cylinder 7.
During production run, as shown in figure 3, the adjustment for passing through rolling line adjusting device, bottom roll position raises and reaches rolling life
Presentation is put, and a kind of trailing type changing rig is in production status.Follow-up connector 5 and roll change oil cylinder 7 swing certain around oil cylinder hinged shaft
Angle, servo-actuated roll change buggy 6 also changes with the relative position of follow-up connector 5, and the wheel of servo-actuated roll change buggy 6 is always maintained at
On machine inner orbit 3, the weight for keeping its stablizing with respect to the position of changing track for roll, servo-actuated roll change buggy 6 is held by machine inner orbit 3
Load, is now servo-actuated roll change oil cylinder when roll change buggy 6 can constrain the position of follow-up connector 5 and ensure to switch to roll change state next time
7 position is accurate.
The operation principle of the present invention：
During roll change operation, servo-actuated roll change buggy 6 follows the action of roll change oil cylinder 7 and moves, and supports follow-up connector 5, auxiliary
Changing rig releases old roller, more renews roller.In production process, bottom roll position raises, and is servo-actuated roll change buggy 6 and follow-up connector 5
Disengaging face contacts, and servo-actuated roll change buggy 6 is still hinged with follow-up connector 5, and the servo-actuated wheel of roll change buggy 6 falls in machine inner orbit
On 3, its weight is born by machine inner orbit 3, does not interfere with normal Rolling Production process, while ensureing that next changing rig is switched to
The position of roll change oil cylinder 7 is accurate during roll change state.
Cover sheet 1 hangs away in roll change, and cover sheet 1 is covered on machine outside track after the completion of roll change operation, plays protection
Machine outside track, the effect for facilitating producers' operation.
Part of the present embodiment without detailed narration and structure belong to the well-known components and common structure or conventional handss of the industry
Section, does not describe one by one here.
