Abstract
The utility model relates to a walking beam lift cylinder segment control structure, this structure adopt two independent control valves to control anterior segment lift cylinder and rear end lift cylinder respectively, and anterior segment lift cylinder and rear end lift cylinder adopt mechanical connection. By means of sectional control of the walking beam lifting cylinder, synchronous lifting can be guaranteed when loads borne by two sections of walking beams are different, the running period of the walking beams is guaranteed to be within a specified range, the conveying speed of steel coils is increased, and the bottleneck problem caused by the fact that the output is limited to increase is thoroughly solved.
Description
Technical field
The utility model relates to a kind of step rate hydraulic actuating cylinder segmentation control structure.
Background technology
In 2150 tandem rolling lines, batch regional coil of strip transportation and adopt step rate, because the coil of strip of transportation is more, adopt two sections step rates.Control system in the past adopts two control cock to control the scheme of two sections step rates simultaneously, and when promptly producing, two control cock only drop into one and can finish lifting action, and just rising or falling speed is slow.If coil of strip weight is approximately equal on two sections step rates, the step rate lifting can realize synchronously; If coil of strip weight is unequal on two sections step rates, then in the uphill process, after lightweight that section was raised to the position, another section just began action, and the decline process is just in time opposite.Because two sections step rate liftings are asynchronous, prolonged the lifting time of step rate, thereby influenced the travelling speed of coil of strip, become the bottleneck of restriction increase of production.
Summary of the invention
The purpose of this utility model provides a kind of step rate lift cylinders segmentation control structure, this structure adopt two independently control cock control leading portion lift cylinders and rear end lift cylinders respectively.By segmentation control to the step rate lift cylinders, guaranteeing simultaneously still can synchronization lifting two sections loads that step rate bears, guarantee that the step rate cycle of run in specialized range, improves the travelling speed of coil of strip, thoroughly solve the bottleneck problem of the restriction increase of production that causes thus.
The utility model is achieved through the following technical solutions:
Step rate lift cylinders segmentation control structure, adopt two independently control cock connect leading portion lift cylinders and back segment lift cylinders respectively, leading portion lift cylinders and back segment lift cylinders adopt mechanical connection.
Compared with prior art, the utility model has the advantages that:
By segmentation control to the step rate lift cylinders, guaranteeing simultaneously still can synchronization lifting two sections loads that step rate bears, guarantee that the step rate cycle of run in specialized range, improves the travelling speed of coil of strip, thoroughly solve the bottleneck problem of the restriction increase of production that causes thus.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-coil of strip
The specific embodiment
See Fig. 1, step rate lift cylinders segmentation control structure, comprise control cock one, control cock two, leading portion lift cylinders and back segment lift cylinders, control cock one control leading portion lift cylinders, control cock two control rear end lift cylinders, adopt mechanical connection between leading portion lift cylinders and the back segment lift cylinders, thereby realize the segmentation control of lifting hydraulic cylinder.
Claims (1)
1, step rate lift cylinders segmentation control structure is characterized in that, adopt two independently control cock connect leading portion lift cylinders and back segment lift cylinders respectively, leading portion lift cylinders and back segment lift cylinders adopt mechanical connection.
