Abstract
The utility model relates to an impact-free hydraulic cylinder guide board lifting device, which is composed of a chain, a hydraulic cylinder, a de-scaling guide device and a guide board. The chain replaces a connecting bar which is originally used, and the upper end of the chain is connected with the hydraulic cylinder on the upper portion of the chain through a pin. The hydraulic cylinder is fixed on the de-scaling guide device through the pin. The lower end of the chain is connected with the guide board through the pin. The hydraulic cylinder and the guide board are connected through adopting the chain, when the guide board is stricken by a belt head of a steel plate with a raised head which is transmitted by a working roller way, the guide board rotates upwards due to force, and the characteristics of the chain determine that the guide board can not transmit the acting force to the hydraulic cylinder due to rotation, which prevents the hydraulic cylinder from impacting. The utility model has the advantages of novel structure, safety, reliability, prolonged service life and the like, and thereby belonging to a novel device which integrates the economy and the practicability.
Description
Technical field
On the de-scaling guide and guards of exempting to impact roughing and finish rolling main mill in the hot rolled steel plate production line that hydraulic cylinder guide plate lifting device is applicable to iron and steel corporation described in the utility model, promote guide plate when being used for working roll and backing roll roll change.
Background technology
At present domestic hot rolled steel plate is produced unit main mill de-scaling guide and guards and is generally all used hydraulic cylinder as the guide plate lifting device, this version is comparatively simple, action is directly convenient, the lifting effect is better, what but the used this lifting device of present most equipment all adopted is hard connection, links to each other with connecting rod between hydraulic cylinder and the guide plate.As everyone knows, on the hot rolled steel plate production line slab take the lead and magnetic tape trailer owing to be subjected to generally all out-of-flatnesses of influence of plastic deformation force, promptly so-called nose phenomenon.This will cause steel plate to take the lead directly to enter roll gap but hit the guide plate of de-scaling guide and guards, its impact will act directly on the lifting device of guide plate by connecting rod---on the hydraulic cylinder, consequently, the bump guide plate that invar plate nose is frequent, make hydraulic cylinder also be subjected to frequent impact, reduce the service life of hydraulic cylinder, also can influence the valve group life-span and the pipeline safety of control hydraulic cylinder simultaneously.At existing problem in the above-mentioned prior art, hydraulic cylinder guide plate lifting device is impacted in a kind of novel exempting from of research and design, and existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is that hydraulic cylinder guide plate lifting device is impacted in a kind of novel exempting from of research and design, frequently clashes into guide plate thereby solve invar plate nose, makes hydraulic cylinder be subjected to the frequent impact problem.Described in the utility modelly exempt to impact hydraulic cylinder guide plate lifting device and formed by connecting rod, hydraulic cylinder, de-scaling guide and guards, guide plate.Its structure is that used connecting rod is substituted by chain.The chain upper end is connected with the hydraulic cylinder on its top by bearing pin.Hydraulic cylinder is fixed on the de-scaling guide and guards by bearing pin.The chain lower end is connected with guide plate by bearing pin.
The technical solution that the utility model proposes is: on original guide and guard structure and form basis of invariable, lifting device changed into by hard connection be flexible coupling, it more precisely is the connected mode that connecting rod is changed into chain, when guide plate be subjected to work roll table carry the steel plate that has nose come take the lead to clash into the time, owing to the stressed rotation that makes progress, the characteristic decision of chain can not given hydraulic cylinder with force transmission because of guide plate rotates, and hydraulic cylinder can be avoided impacting.Can eliminate the steel plate impulsive force of being transmitted by guide plate like this.This utility model major advantage is as follows:
1, simple and practical, conveniently existing equipment is undergone technological transformation, can utilize former guide and guards to undergo technological transformation, with low cost.
2,, making inclination that the guide and guard guide plate produces at the width range unbalance stress to lifting device because the flexibility of chain---the influence of hydraulic cylinder becomes and can ignore.
3, owing to avoid impacting, pipeline fittings working conditions such as hydraulic cylinder and valve group thereof are greatly improved.Naturally just can significantly improve its service life, thereby save cost.
Description of drawings
The utility model has an accompanying drawing, wherein
Accompanying drawing: 1, exempt to impact hydraulic cylinder guide plate lifting device structural representation.
Among the figure: 1, de-scaling guide and guards 2, hydraulic cylinder 3 chains 4, guide plate 5, steel plate 6, work roll table
The specific embodiment
Specific embodiment of the utility model as shown in Figure 1, be the rolling thick 20mm that is, wide be 2800mm by the hot rolled steel plate milling train de-scaling guide and guard guide plate lifting device of rolled steel plate 5 usefulness, its structure comprises hydraulic cylinder 2, chain 3, de-scaling guide and guards 1, guide plate 4.The upper end of chain 3 is connected with the hydraulic cylinder 2 on its top by bearing pin.Hydraulic cylinder 2 is fixed on the de-scaling guide and guards 1 by bearing pin.The lower end of chain 3 is connected with guide plate 4 by bearing pin.That is to say that hydraulic cylinder 2 adopts chain to be connected with guide plate 4, when guide plate 4 be subjected to work roll table 6 carry the steel plate that has nose 5 of coming take the lead to clash into the time, owing to the stressed rotation that makes progress, the characteristic decision guide plate of chain can not given hydraulic cylinder with force transmission because of rotation, makes hydraulic cylinder can avoid impacting.
