CN209411593U - Device for simply and conveniently replacing guard plates on line of rolling mill - Google Patents

Abstract

The utility model relates to a device of guard is portably changed on line to rolling mill, including wire rope, couple, the three extreme point that forms after the fifty percent discount of a wire rope all is connected with fixed couple, and the diameter of couple is not more than the wire rope diameter, and wire rope spanes on the deflector roof beam, and the couple hook is hung on guard. The advantages are that: overall structure is simple, and easily field operation utilizes the deflector roof beam can follow the function that the roller promoted on the rolling mill, draws out the guard from whole deflector roof beam through wire rope and couple, and the reuse is the same mode, targets in place the installation of new guard, has reduced manual intensity of labour and the potential safety hazard that uses the crowbar to dismantle the guard, has reduced the process that needs the crane hoist and mount guard, has improved production efficiency. Adopt supplementary hook, can make the removal of guard more stable, the hook is more firm.

Description

The device of plate is defended in a kind of online easy replacement of milling train

Technical field

The utility model relates to the devices that plate is defended in a kind of online easy replacement of milling train.

Background technique

BD2 milling train is in rolling process since the case where defending plate under top often occurs in tapping state labile, it is therefore desirable to Plate is defended in replacement in the case where (not extracting milling train out) online.It can not be set using liftings such as crane or hoists since working position is narrow It is standby, it is only capable of manually being pulled out manually with crowbar and defends plate and installed manually, it is time-consuming and laborious.

Summary of the invention

In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a kind of online easy replacements of milling train to defend plate Device can adapt to narrow working environment, can will defend plate and be installed to guide beam, and reduce labor intensity, and improve production efficiency.

To achieve the above object, the utility model is achieved through the following technical solutions:

The device of plate, including wirerope, hook are defended in a kind of online easy replacement of milling train, are formed after steel cable doubling Three endpoints are connect with fixed hook, and the diameter of hook is not more than wirerope diameter, and wirerope is linked up with across on guide plate beam It is hooked on and defends on plate.

It further include auxiliary hook, auxiliary steel cable, end positions and auxiliary steel cable both ends before wirerope doubling are fixed and connected It connects, assists being fixedly connected with auxiliary hook on steel cable.

The hook is U-shaped structure, and the end of U-shaped structure is crotch structure.

Compared with prior art, the utility model has the beneficial effects that

The device overall structure that plate is defended in the online easy replacement of milling train is simple, is easy to execute-in-place, can be with rolling using guide plate beam The function that machine upper roller is promoted will be defended plate from whole guide beam and be pulled out by wirerope and hook, then in a like fashion, will It newly defends plate to be installed in place, reduces the labor intensity and security risk for defending plate using crowbar disassembly by hand, reduce and need crane The process for defending plate is lifted, production efficiency is improved.Using auxiliary hook, the movement for defending plate can be made more stable, hook it is more firm Gu.

Fig. 2 is the side view of utility model works state.

Fig. 3 is the connection schematic diagram one of wirerope and hook.

Fig. 4 is the connection schematic diagram two of wirerope and hook.

In figure: 1- wirerope 2- hook 3- defends plate 4- guide plate beam 5- auxiliary hook.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings of the specification, it should be noted that the utility model Implement embodiment not limited to the following.

See Fig. 1-Fig. 4, the device of plate, including wirerope 1, hook 2, steel cable are defended in a kind of online easy replacement of milling train Three endpoints formed after 1 doubling are connect with fixed hook 2, and the diameter for linking up with 2 is not more than 1 diameter of wirerope, and wirerope 1 is horizontal Across on guide plate beam 4, hook 2, which is hooked on, to be defended on plate 3.

The device that plate is defended in the online easy replacement of milling train further includes auxiliary hook 5, auxiliary steel cable, before 1 doubling of wirerope End positions are fixedly connected with auxiliary steel cable both ends, assist being fixedly connected with auxiliary hook 5 on steel cable.It is hooked in hook 2 and defends plate 3 Afterwards, it will be hooked across the wirerope 1 of guide plate beam 4 using auxiliary hook 5, it is more firm to make to defend plate 3.Hook 2 is U-shaped structure, U-shaped The end of structure is crotch structure, and the both ends distance of U-shaped structure is identical as the pitch-row for defending plate 3.

Plate 3107kg is defended under existing 2 hole, plate 3167kg is defended under 3 holes, and when specific operation, the hook 2 of wirerope 1 is guided to On guide plate beam 4, hook 2 passes through the small gaps at 4 top of guide plate beam, and wirerope 1 is across guide plate beam 4, by three 2 difference of hook Hook need replacing defend plate 3, using milling train upper roller enhanced feature drive guide plate beam 4, plate 3 will be defended from entirety by equipment dynamic It is pulled out on guide beam.Again with hook 2 hook it is new defend plate 3, then decline roll and newly will defend plate 3 and be installed on whole guide beam. If plate 3 is defended under 2 holes, then the hook 2 of 4 two sides of guide plate beam is hooked on respectively on 2 holes.

It adopts present apparatus replacement and defends plate 3, reduce the labor intensity and security risk for defending plate 3 using crowbar disassembly by hand, subtract Lack the process for needing crane lifting to defend plate 3, improves production efficiency.Reduce the manually installed labor intensity for defending plate 3, reduces During security risk.3 time-consuming of plate is defended 5 minutes using present apparatus replacement, the time for defending plate 3 than replacement by hand saves 10- 15 minutes, improve production efficiency.Reduce crane and the use cost of craneman.
