Description

A kind of Multi-Roll Cluster Mill Changing Gear
Technical field
The present invention relates to suspender, more particularly, relate to a kind of Multi-Roll Cluster Mill Changing Gear.
Background technology
In the multi-roll mill of existing use; especially 20 roller sendzimir mills; its roll change frequency is very high; average every rolling one coil volume need to be changed twice of working roll; change 40 left and right of working roll average every day, changes once left and right of an intermediate calender rolls, and each roll change unit must be shut down wait; and the quality of changing the device of roll has very important impact to roll change, the production efficiency on unit and production capacity have very large impact.
At present worldwide; the changing rig that 20 roller sendzimir mills use mostly is manual changing rig; the working roll of required replacing or intermediate calender rolls are placed on roll change buggy; dolly is manually moved to roll change position; re-use artificial method working roll or intermediate calender rolls are advanced to rolling mill body; thereby complete whole roll change process, and average each roll change need to be shut down about 20 minutes.Dolly Main Function used is for changing working roll and changing an intermediate calender rolls, adopt complete manual mode to change, on roll change buggy, place roller rack, in the time changing working roll, roll change buggy moves to milling train position, adopt the mode of manually adjusting position height to carry out, operating personnel adopt the mode of manual promotion or pull roll to change roll.Manually roll change buggy has the roll rollgang that rises and decline, this position, roller-way left and right is substantially fixing, can only regulate height, therefore while adopting manual roll change buggy to change an intermediate calender rolls there is larger deviation in position accuracy of alignment, need operating personnel manually by an intermediate calender rolls toward left side or right side be shifted, cause operation very loaded down with trivial details, the precision of Position Control is extremely low, and security is also very poor.
Summary of the invention
For the above-mentioned shortcoming existing in prior art, the object of this invention is to provide a kind of Multi-Roll Cluster Mill Changing Gear, the dress of taking out of can finish the work accurately, fast roller and intermediate calender rolls.
For achieving the above object, the present invention adopts following technical scheme:
This Multi-Roll Cluster Mill Changing Gear comprises the dolly that travels, be located at the fixture dolly and the roller frame that travel on dolly, be located at crane on fixture dolly, be located at the roll clamp of crane one end, the dolly that travels is provided with the horizontal cross track for fixture carriage walking, roller frame is fixedly arranged on an end of the dolly that travels, fixture dolly is provided with the horizontal long rails for crane sidesway, roll clamp comprises the clamp seat be located on crane, is located at upper and lower clamp and clamp oil cylinder on clamp seat, and clamp oil cylinder is connected with upper clamp by swing arm.
Between described upper and lower clamp, be also provided with a roll push rod, roll push rod end is connected with control cylinder.
On described travel dolly and fixture dolly, be respectively equipped with to drive the CD-ROM drive motor of wheel separately.
Described crane is provided with elevating screw and lifting motor, and lifting motor is connected with elevating screw, and clamp seat is located on elevating screw.
On described crane, be also provided with sidesway motor, on fixture dolly, be also provided with the sidesway screw mandrel being connected with sidesway motor.
On described clamp seat, be also provided with clamp rotating shaft.
In technique scheme, Multi-Roll Cluster Mill Changing Gear of the present invention comprises the dolly that travels, be located at the fixture dolly and the roller frame that travel on dolly, be located at the crane on fixture dolly, be located at the roll clamp of crane one end, the dolly that travels is provided with the horizontal cross track for fixture carriage walking, roller frame is fixedly arranged on an end of the dolly that travels, fixture dolly is provided with the horizontal long rails for crane sidesway, roll clamp comprises the clamp seat of being located on crane, be located at upper on clamp seat, lower clamp and clamp oil cylinder, clamp oil cylinder is connected with upper clamp by swing arm.Adopt this changing rig can realize fast, accurately, the roll change of safety and efficiently, solved the problem that current puzzlement multi-roll mill roll change frequency is high, efficiency is low, greatly improved the production capacity of milling train.
Brief description of the drawings
Fig. 1 is the structural representation of changing rig of the present invention.
Detailed description of the invention
Further illustrate technical scheme of the present invention below in conjunction with drawings and Examples.
Shown in Fig. 1, Multi-Roll Cluster Mill Changing Gear of the present invention comprises the dolly 1 that travels, be located at the fixture dolly 2 and the roller frame 3 that travel on dolly 1, be located at the crane 4 on fixture dolly 2, be located at the roll clamp of crane 4 one end, the dolly 1 that travels is provided with the horizontal cross track 5 of walking for fixture dolly 2, roller frame 3 is fixedly arranged on an end of the dolly 1 that travels, in order to deposit spare roll 6, fixture dolly 2 is provided with the horizontal long rails 7 for crane 4 sidesways, roll clamp comprises the clamp seat 8 of being located on crane 4, be located at upper on clamp seat 8, lower clamp 9, 10 and clamp oil cylinder 11, clamp oil cylinder 11 is connected with upper clamp 9 by swing arm 12, fold up roller in order to control.Between described upper and lower clamp 9,10, be also provided with a roll push rod 13, roll push rod 13 ends are connected with control cylinder.On described travel dolly 1 and fixture dolly 2, be respectively equipped with to drive the CD-ROM drive motor 14 of wheel 21 separately.Described crane 4 is provided with elevating screw 15 and lifting motor 16, and lifting motor 16 is connected with elevating screw 15, and clamp seat 8 is located on elevating screw 15.On described crane 4, be also provided with sidesway motor 20, on fixture dolly 2, be also provided with the sidesway screw mandrel 18 being connected by driving chain with sidesway motor 17.On described clamp seat 8, be also provided with clamp rotating shaft 19, can be used for the rotation of whole fixture.
In the time of roller replacing operation, advancing of the dolly 1 that travels, fixture dolly 2 controlled automatically by CD-ROM drive motor 14 respectively, between CD-ROM drive motor 14 and wheel 21, can be connected by driving chain 22; The sidesway of crane 4 is controlled automatically by sidesway motor 17; The lifting of clamp seat 8 and rotation realize by lifting motor 16 and clamp rotating shaft 19 respectively.By above-mentioned measure, can realize comprehensive automatic roll change.And, after being clamped by upper and lower clamp 9,10, spare roll 6 packs into after frame, put in place owing to relying on clamp can not ensure that roll packs into, therefore can promote roll push rod 13 by control cylinder, after clamp is opened, advance milling train to target location on roll by push rod 13, realize accurately location.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, variation, modification to the above embodiment all will drop within the scope of claims of the present invention.
