Technical field
The utility model relates to operation roll of mill roll change field, particularly a kind of formula hydraulic cylinder changing rig of moving one's steps.
Background technology
At present, work roll changing all adopts automatic changing rig in the domestic rolling of sectional iron unit, changing rig is made up of Traverse Displacement Unit and push-pull device at fixed two parts, it is the centering framework window that Traverse Displacement Unit is responsible for working roll, push-pull device at fixed is responsible for working roll system is pushed and pull out framework window, push-pull device at fixed makes working roll system move forward to the operating position and stop along certain tracks when pushing working roll and be; The structure of push-pull device at fixed is general to be driven with big stroke push-and-pull hydraulic cylinder, and the roll change hook of the roll changing carriage that push-and-pull cylinder hook and loading working roll are is connected to finish and pushes and pull out action, and current this structure is widely adopted.
But above-mentioned kind of roller replacing mode, need could drive the working roll roller than the push-and-pull hydraulic cylinder of big stroke is the action of finishing roll change, push-and-pull hydraulic cylinder belongs to long stroke hydraulic cylinder, volume is longer, take up an area of greatlyyer, structure is compact inadequately, and long-stroke push-and-pull roll change hydraulic cylinder in use, when running into 950 and during above shape rolling mill, because working roll roller system is heavier, needed hydraulic cylinder is also bigger, when designed capacity is not enough, can't finish push pull maneuver, so need the bigger hydraulic cylinder of cylinder diameter, because roller system is heavier, stroke is longer, the cylinder bar is yielding, and replacement cost is higher.
Summary of the invention
The purpose of this utility model provides a kind of output interface resource that takes full advantage of existing PLC and realizes the node expansion, finishes the PLC output point expansion board of automatic control.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of formula hydraulic cylinder changing rig of moving one's steps, comprise fixed support, the hydraulic cylinder of advancing, vehicle frame, the vehicle frame track, wheel assembly one, lifting hydraulic cylinder, connecting rod, contiguous block, slide block, wheel assembly two, rack gear arrangement, base, get on the right track and the roll change hook, described susceptor surface is provided with the vehicle frame track and gets on the right track, rack gear arrangement by wheel assembly two and get on the right track be equipped with top in base, rack gear arrangement one end is provided with the roll change hook, vehicle frame is by the side in base of being equipped with of wheel assembly one and vehicle frame track, vehicle frame one end is connected with fixed support by the hydraulic cylinder of advancing, the vehicle frame other end is assembled together by slide block one end and rack gear arrangement, the slide block other end is connected with lifting hydraulic cylinder one end with contiguous block by connecting rod, and the lifting hydraulic cylinder other end is fixed on the vehicle frame.
Compared with prior art, the beneficial effects of the utility model are:
A kind of formula hydraulic cylinder changing rig of moving one's steps, have reasonable in design, compact conformation, simple and practical, change convenience, reliable operation, energy savings, the little characteristics in occupation of land space, replacing owing to the roller of finishing the work with step-by-step movement push-and-pull campaign, effectively shortened the stroke of roll change, avoided the deficiency in roll change space, make things convenient for the maintenance of changing rig, prevented the distortion of hydraulic cylinder cylinder bar and the leakage of hydraulic oil, saved equipment cost and maintenance cost greatly.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further specified:
As shown in Figure 1, a kind of formula hydraulic cylinder changing rig of moving one's steps of the utility model, comprise fixed support 1, the hydraulic cylinder 3 of advancing, vehicle frame 4, vehicle frame track 6, wheel assembly 1, lifting hydraulic cylinder 9, connecting rod 10, contiguous block 13, slide block 14, wheel assembly 2 16, rack gear arrangement 17, base 18, get on the right track 19 and roll change hook 20, described base 18 surfaces are provided with vehicle frame track 6 and get on the right track 19, rack gear arrangement 17 is by wheel assembly 2 16 and 19 be equipped with in the top of base 18 of getting on the right track, rack gear arrangement 17 1 ends are provided with roll change hook 20, vehicle frame 4 is equipped with in the side of base 18 by wheel assembly 1 and vehicle frame track 6, vehicle frame 4 one ends are connected with fixed support 1 by the hydraulic cylinder 3 of advancing, vehicle frame 4 other ends are assembled together by slide block 14 1 ends and rack gear arrangement 17, slide block 14 other ends are connected with lifting hydraulic cylinder 9 one ends with contiguous block 13 by connecting rod 10, and lifting hydraulic cylinder 9 other ends are fixed on the vehicle frame 4.
