Description
Technical field
The utility model belongs to the rolling mill auxiliary equipment technical field, especially relates to a kind of step-by-step movement changing rig of non-ferrous metal strip-mill strip.
Background technology
In the Rolling Production process, after roll used a period of time, its surface smoothness can reduce, thereby influences strip surface fineness, and the strip quality that rolls out is descended; Therefore, roll needs periodic replacement.
For aluminium plate band rolling mill, in the particularly old-fashioned milling train, traditional roll-changing method is to cooperatively interact with crane and manual work, and breaker roll carries out that push-and-pull realizes.If milling train does not dispose the roll change track, also need the artificial track that pushes, this roller replacing mode is wasted time and energy, and changes roll several hrs easily, and nearly tens hours, and dangerous.
Summary of the invention
The utility model technical problem to be solved provides a kind of step-by-step movement changing rig, and this device can be practiced thrift field operation space and activity duration, and is time saving and energy saving during application.
In order to realize the foregoing invention purpose, following technical scheme is adopted in the invention:
A kind of step-by-step movement changing rig comprises roll change frame, roll change buggy and is fastened on the trapped orbit on the roll change frame; Also comprise hydraulic cylinder, sliding rail, said sliding rail places on the trapped orbit, and said hydraulic cylinder places roll change frame afterbody through attaching parts, and in the vertical direction, and hydraulic cylinder is positioned on the sliding rail; Between said sliding rail and the trapped orbit positioner is set, said hydraulic cylinder is connected with sliding rail with roll change buggy through guider.
Be better implement the invention, said sliding rail is the tower structure that crossbeam and longeron are formed.
Be better implement the invention, slide plate is inlayed in said sliding rail bottom.
Be better implement the invention, said hydraulic cylinder is set to the secondary telescopic hydraulic cylinder.
Be better implement the invention, said guider comprises contiguous block, bearing pin and latch, and said latch is arranged in the contiguous block.
Be better implement the invention, said positioner comprises locating piece and latch, and said latch inserts locating piece location sliding rail and trapped orbit.
Because adopt aforesaid technical scheme, the invention produces following good effect:
1, the step-by-step movement changing rig of the invention makes through positioner to have the accurate localization device between trapped orbit and the sliding rail, guarantees the reliability of roll change track structure and function.
2, hydraulic cylinder one cylinder is dual-purpose, both can drive roll change buggy, also can drive sliding rail; Cost has been practiced thrift in the dual-purpose realization of one cylinder.
3, the many usefulness of latch one pin both can be used when the Driven by Hydraulic Cylinder sliding rail, can be used for the fixing of sliding rail operating position and home position again.
4, adopt Driven by Hydraulic Cylinder than artificial time saving and energy saving, improved production efficiency, and safer.
5, adopt the secondary telescopic hydraulic cylinder to compare with adopting common long stroke hydraulic cylinder, it is about 1/3 that length reduces, and occupies little space.

The specific embodiment
In conjunction with Fig. 1, Fig. 2, the step-by-step movement changing rig of present embodiment mainly comprises: sliding rail 1, trapped orbit 2, roll change frame 3, secondary telescopic hydraulic cylinder 4 and the roll change buggy 5 of the tower structure that crossbeam and longeron are formed; Trapped orbit 2 is fastened on the roll change frame 3, and roll change frame 3 afterbodys connect hydraulic cylinder through attaching parts; Sliding rail places on the trapped orbit, and the slide plate that antifriction material is processed is inlayed in the sliding rail bottom, can reduce frictional resistance; Between sliding rail and the trapped orbit positioner is set, hydraulic cylinder is connected with sliding rail with roll change buggy through guider.In the vertical direction, hydraulic cylinder is positioned on the sliding rail.
In conjunction with Fig. 3, guider comprises contiguous block 9, bearing pin 8 and latch 10, and said latch 10 is arranged in the contiguous block 9, utilizes latch can realize the driving and sliding rail the fixing on trapped orbit of 4 pairs of roll change buggies 5 of hydraulic cylinder and sliding rail 1.
In conjunction with Fig. 4; The step-by-step movement changing rig has raw bits and two positioning functions of working position; Positioner comprises L type locating piece, square locating piece and latch 10, and the latch 10 of on the position of needs, packing into can be realized the accurate location of sliding rail, pulls out latch 10; Be placed on contiguous block 9 places of guider, can drive sliding rail.
In conjunction with Fig. 1, when changing top roll, top roll is mentioned with bascule, latch 10 is contained in contiguous block 9 places, utilize the elongation of secondary telescopic hydraulic cylinder 4 one-levels, sliding rail 1 is advanced frame, pull out latch 10, be inserted into the place, location, sliding rail is fixed.The elongation through the second level is delivered to milling train fore side precalculated position with oil cylinder guider and oil cylinder earrings 7 again, and top roll falls, and the roller of top roll is fallen on the track.Hook on the bearing block links to each other through bearing pin 8 with oil cylinder earrings 7, can top roll be pulled out memorial archway, with crane top roll is hung away.
In conjunction with Fig. 2, when changing lower roll, after top roll was pulled out, secondary telescopic hydraulic cylinder 4 moved on to sliding rail 1 outside the memorial archway, with bascule lower roll was mentioned, and again sliding rail 1 was advanced into working position.Roll change buggy 5 is hung on the slip roller-way, and dolly hook 6 links to each other through bearing pin 8 with oil cylinder earrings 7, and secondary telescopic hydraulic cylinder 4 is fallen roll change buggy 5 propelling frames on the roll change buggy 5 with lower roll, pulls out frame then, hangs away with crane.
Operation when new roller is installed reversed in order when unloading old roller.
