Description
Technical Field
The utility model relates to a roll changing device, more specifically relate to a seal box transition roller platform.
Background
The seal box and the transition roller are used as key equipment for connecting the tin bath and the annealing kiln and mainly comprise an upper box body, a lower box body, a roller body unit, an internal retaining curtain, a tin wiping device and the like. The transition roller is composed of 3 transition rollers, the main function of the transition roller is to convey a glass belt coming out from the tail end of the tin bath, the temperature of the glass belt is reduced to about 600 ℃ after passing through the transition roller and then the glass belt enters an annealing kiln, and meanwhile, a tin wiping device below the roller body unit clears away tin slag brought out from the tin bath on the lower surface of the glass. The graphite tin wiping device under the roller body can play a sealing role simultaneously except removing tin slag remained on the roller on the lower surface of glass, so that each roller body unit is in an independent space state, and further, the phenomenon that air enters a tin bath through a sealing box and is subjected to oxidation reaction with molten tin is avoided.
In the conventional seal box transition roller structure in China, the tin wiping device usually adopts a bridge structure to support a graphite block of the tin wiping device, and a plate spring is adopted to support the graphite block to realize that the lower part of the roller is in close contact with the graphite block. The plate spring gradually generates deflection in the environment of 600 ℃, generally about 20-25 mm; meanwhile, the bridge structure and the roller can generate deflection, and the deflection generated by the roller applies pressure to the graphite block, so that the graphite block structure is deformed, and therefore the tin wiping device is easy to generate a waist collapse phenomenon at high temperature, the tin wiping device cannot be completely and tightly contacted with the roller, and tin compound accumulations such as SnS, SnO and the like which are difficult to remove are generated on the surface of the steel roller in the long term. On the one hand, easily lead to glass lower surface fish tail, seriously influence the play roller quality of shaping glass, on the other hand, the tin thing can lead to the corruption of roll body self. Therefore, in the modern float glass process, the maintenance of the transition roller and the online roller change become more and more common, which puts higher requirements on the structure of the main equipment of the transition roller, and ensures how to realize the efficient, safe and stable online roller change under the condition of normal operation of the glass ribbon in a high-temperature environment.

After the water jacket 22 and the support 23 are fixed by the two first connecting pieces 24, the roller 2 is retained above the support 23 and between the two water jackets 22.
Referring to fig. 1, 2 and 3, the second connecting member 25 is an L-shaped structure and symmetrically fixed on the outer end surfaces of the two water jackets 22, the vertical plate of the second connecting member 25 is fixed on the outer end surfaces of the water jackets 22 through bolts, and the horizontal plate is provided with screw holes for bolting with the roll-changing trolley 26 and the auxiliary moving trolley 29.
Traditional online roll change needs to be taken out support piece 23 together, and intensity of labour is big, and work efficiency is low, and the factor of safety of operation is low under the high temperature, and improper operation easily causes heeling of whole roll body unit, and the direct economic loss who causes is great.
When using the utility model discloses during the embodiment, support piece 23 and water jacket 22 are connected to first connecting piece 24, when carrying out online roll change, demolish the screw of connecting first connecting piece 24, demolish first connecting piece 24, make support piece 23 and water jacket 22 separately, take water jacket 22 and roller 2 out the change, need not take support piece 23 out together, and is more convenient.
The fixing part of the first connecting piece 24 connected with the supporting piece 23 is provided with a kidney-shaped hole, and when the roller is replaced, the bolt is slowly loosened and falls along the kidney-shaped hole, so that the transition roller 21 falls slowly.
When removing the first connecting member 24, only the bolts connecting the first connecting member 24 and the water jacket 22 and the bolts connecting the first connecting member 24 and the support member 23 need to be removed.
The specific dismantling process is as follows: after the device for wiping tin by changing the roller is descended, the auxiliary supporting pieces 28 at the two sides of the transition roller 21 are adjusted to be 15-20mm lower than the lower surface of the shaft head, the clutch at the position where the roller needs to be changed is disconnected, the universal transmission shaft at the transmission side is disconnected, and the roller 2 is changed from mechanical rotation to manual rotation. Loosening the adjusting bolt of the first connecting piece 25 to enable the roller 2 to slowly fall, locking the bolt of the first connecting piece 24 after the shaft head of the roller 2 and the auxiliary supporting piece 28 absorb the force, detaching the first connecting piece 24 after the trolleys are connected through the roller changing trolley 26 and the auxiliary moving trolley 29 connected through the second connecting piece 25, detaching the auxiliary supporting piece 28 on the non-transmission side, dragging the roller changing trolley 26, enabling the auxiliary moving trolley 29 to enter the guide groove of the roller supporting piece, and slowly pulling out the roller 2. After the roller 2 is replaced, the auxiliary moving trolley 29 is pushed into the guide groove, the roller changing trolley 26 is pushed to enable the roller to enter the box body, after the shaft part of the transmission side is in place, the auxiliary supporting piece of the non-transmission side is installed, the first connecting piece 24 is connected, and the trolley and the second connecting piece 25 are detached; after the disassembly is finished, the roller 2 is adjusted to the position of the process elevation by adjusting the auxiliary supporting piece and the first connecting piece 24 simultaneously, the bolt of the first connecting piece 24 is locked, the auxiliary supporting pieces on the two sides are lowered simultaneously, and after the disassembly is finished, the transmission shaft on the transmission side and the clutch are connected, so that the whole roller replacement is finished.
Example 2

Referring to fig. 1, 2 and 3, the water jacket 22 of one end of the roller 2 is connected with the auxiliary moving trolley 26 through the second connecting piece 25, and the auxiliary moving trolley 26 is supported by the wheels to move. For moving the roller 2 when removing the roller 2.
The support 23 is provided with a guide groove (not shown) on its top surface facing the roller 2, the guide groove extending in the same direction as the direction of movement of the roller 2. The auxiliary moving cart 26 moves along the guide groove.
When the supporting piece 23 is installed, the deformation amount of the roller 2 below the hot table is reserved between the supporting piece and the roller 2, so that the roller 2 cannot damage the equipment when being deformed.
The water jacket 22 of the non-drive end of the roller 2 shown in fig. 2 is detachably mounted with a roll-changing trailer 29 through a second connecting member 25. When the roller 2 is detached, the roller-changing trailer 29 is connected to the water jacket 22 by a bolt and the second connecting member 25, and the roller 2 and the water jacket 22 are pulled out by moving the roller-changing trailer 29.
The support piece 23 is provided with a guide groove for the auxiliary moving trolley 26 to move, the support piece 23 reserves the deformation under the hot table for the roller 2 during installation, and when the roller is replaced on line, the auxiliary moving trolley 26 is installed on the water jacket 22 at the transmission end of the roller 2 by the second connecting piece 25 and is pulled out through the guide groove in a moving mode, so that the roller is replaced on line more conveniently.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
