Abstract
The utility model relates to a broken roll taking out device, which is especially suitable for taking out sectionally the broken mill rolls of the four-high mill of the closed type housing window. The utility model is mainly composed of a roll head, a carrier frame, a connecting plate, etc., the utility model is used by matching with a C-shaped hook and a crane, the broken upper Supporting roll and the broken lower Supporting roll can be taken out conveniently, the whole taking out process is not more than 20 minutes, the rolling mill can gain much production time, and the rolling mill can create much economic benefit.
Description
The utility model relates to a kind of roll breakage withdrawing device, and the roll that belongs to rolling mill is changed and repair apparatus.Segmentation after the four-high mill roll that is specially adapted to closed memorial archway disconnects is taken out.
The memorial archway of four-high mill mostly is enclosed, for the convenience of overhauling and safeguarding, needs to be provided with changing rig in the workshop.
Before the utility model was made, steel rolling mill's changing rig commonly used was the crane of a kind of having of " C " shape suspension hook.This apparatus features is that equipment is simple, and is easy to operate, and obtained using preferably in exchanging complete roll practice for.If but in a single day the roll of milling train fractures, then this device can only take out the half roll breakage of changing side, and the taking-up of remaining half roller is seemed at a loss what to do, generally manyly carries out askew skewing after tying up with steel cable and hangs, whole process need influence bigger to production with 10～20 hours sometimes.
The purpose of this utility model just provides a kind of roll breakage withdrawing device, can not only take out two sections rolls of disconnection fast, also can realize once taking out to the roll of not disconnected and cracking (may disconnect when taking out).
Roll breakage withdrawing device of the present utility model as shown in drawings.
Fig. 1, roll breakage withdrawing device structural representation.
Roll breakage withdrawing device of the present utility model is mainly by roller head (1), connecting plate (2), carriage formations such as (3), carriage wherein (3) termination is provided with a baffle plate (4), this roll breakage withdrawing device connects with " C " type suspension hook (5) fast by roller head (1), two sides respectively have block (7), prevent that the body of roll is crooked.The support roll of four-high mill is made up of last support roller and following support roller, when wherein last supporting axis fractures, need earlier depressing of transmission side to be compressed, changing side is depressed to lift again and is used " C " shape suspension hook to take out the changing side roll breakage, use " C " shape suspension hook then, connect roll breakage withdrawing device of the present utility model by roller head (1), and by crane its memorial archway window from changing side is put in another and block under the roller (6), slowly lift the roll breakage withdrawing device again till carriage (2) holds up the roll breakage (6) of band bearing housing and makes baffle plate (4) block the bearing housing of roll breakage, final level shifts out the roll breakage withdrawing device of holding roll breakage and gets final product.And when support roller fractures down, take out the changing side roll breakage with " C " shape suspension hook earlier, use " C " shape suspension hook to plug the off-axis withdrawing device then, and put in the top that another blocks roller from the changing side memorial archway window, again by manually roll breakage being bundled in the below of carriage (2), slowly mention again at last and level shifts out with steel cable.
Roll breakage withdrawing device of the present utility model is simple in structure, easy to operate, and the maximum duration of taking out two half rollers is no more than 20 minutes, can be steel rolling mill and wins the more production time, creates more economic benefit.
Claims (3)
1, a kind of roll breakage withdrawing device mainly by roller head (1), connecting plate (2), carriage formations such as (3), is characterized in that roller head (1) and carriage (3) connect by connecting plate (2).
2, roll breakage withdrawing device according to claim 1 is characterized in that there is a plate washer (4) termination of carriage (3).
