Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of installation and disassembly of vertical roll mills for strip steel, and particularly relates to a new type of disassembly and assembly device for vertical roll mills. Background Art
[0002] A vertical roll mill is a key device for rolling metal plates such as steel and aluminum. It can roll metal plates longitudinally or transversely to achieve the required thickness and width. During maintenance and repair, the disassembly and assembly of a vertical roll mill is a complex and technically demanding task, especially when replacing core components such as rolls.
[0003] Currently, the vertical roll mills used in the newly built 2250 strip production line do not have a dedicated disassembly and assembly device. Only rely on operators to use a crane for hoisting. And during the alignment stage of the holes and shafts of the mill bearing housing and the roll, rely on the visual inspection of the operator for alignment, which is very unfavorable for the protection of the bearing and causes collision damage; every time the vertical roll is disassembled and assembled, it is necessary to first flip the bearing housing on the operation side, then vertically hoist the roll and insert it into the bearing of the bearing housing, and then hoist and insert the bearing housing on the drive side into the roll. During this process, it is very easy to drop and cause safety accidents; every operation requires at least 3 people to cooperate to ensure the smooth assembly of the bearing housing and the roll, which is time-consuming and laborious, and the operation efficiency is low.
[0004] Therefore, there is an urgent need to design a new type of disassembly and assembly device for vertical roll mills to solve the problems of no dedicated device, only using a crane for hoisting, very easy to drop and cause safety accidents, and low operation efficiency. Content of the Utility Model
[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a new type of disassembly and assembly device for vertical roll mills.
[0006] The technical solution adopted by the utility model to solve its technical problems is: a new type of disassembly and assembly device for vertical roll mills, including a roll stop and a roll stand. The roll stand is arranged inside the roll stop. The roll stop is provided with a roll baffle, and the roll stand is provided with a nylon stop block and a support plate.
[0007] Specifically, the roll stop is used to limit the vertical roll to be disassembled.
[0008] Specifically, the roll baffle is provided with a stop hole, and the stop hole is made into an arc shape according to the shape of the vertical roll to protect the vertical roll and prevent it from being bruised.
[0009] Specifically, the roll stand is located inside the roll stop, and the roll stand limits and protects the middle roll ring of the vertical roll.
[0010] Specifically, there are two nylon stoppers. The nylon stoppers are provided with inclined surfaces and are arranged inside the roll stand. The nylon stoppers and the inclined surfaces are used to stabilize and prevent slipping of the vertical rolls.
[0011] Specifically, the support plate is arranged at the bottom of the roll stand. The support plate is used for vertically installing on the roll stand, and the support plate supports the inside of the roll stand and the roll stopper.
[0012] The utility model has the following beneficial effects:
[0013] The novel vertical roll mill disassembly and assembly device designed by the utility model: 1. Through the designed and manufactured special disassembly and assembly device, the operation accuracy can be greatly improved, the collision accident during roll alignment can be avoided, and the assembly accuracy of the rolling mill can be improved.

[0022] The following will further clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1:
[0024] As shown Figures 1 - 5 in the figure, a disassembly and assembly device for a new type of vertical roll mill includes a roll stop 1 and a roll stand 2. The roll stand 2 is arranged inside the roll stop 1. A roll baffle 1.1 is provided on the roll stop 1, and a nylon block 2.2 and a support plate 2.1 are provided on the roll stand 2.
[0025] When the vertical roll mill needs to be disassembled and assembled, the roll stop 1 of the disassembly and assembly device for the new type of vertical roll mill is closely attached to the upper end of the vertical roll 3. The roll baffle 1.1 on the roll stop 1 is provided with a stop hole 1.2, and the stop hole 1.2 is an arc shape consistent with the upper part of the vertical roll 3. The stop hole 1.2 is used to protect the vertical roll 3 from being bruised, and the roll stop 1 and the roll baffle 1.1 are used to protect and limit the vertical roll 3.
[0026] The roll stand 2 is arranged inside the roll stop 1. The roll stand 2 is used to fix and limit the roll ring of the middle part of the vertical roll 3. A nylon block 2.2 is arranged inside the roll stand 2. The nylon block 2.2 is a structure with an inclined surface. The nylon block 2.2 is used to make the roll ring of the vertical roll 3 fit better and play an anti-slip and stabilizing role. A support plate 2.1 is further arranged at the lower part of the roll stand 2. The support plate 2.1 is used to support the roll stop 1 and the roll stand 2 to make the structure more stable.

[0029] 2. Then, according to the center line size of the roll ring of the vertical roll 3, determine the roll placement position and size of the disassembly and assembly device for the new type of vertical roll mill, so that it can be ensured that the vertical roll 3 will not roll after being placed, and will not cause the center line to shift and cannot ensure that the bearing hole of the bearing seat corresponds to the axis of the vertical roll 3 on the same left and right center line, and will not block the disassembly and assembly of the bearing seat.
[0030] 3. Finally, design the nylon block 2.2 according to the maximum diameter and minimum diameter of the vertical roll 3, so that it can be ensured that the vertical roll 3 can be firmly placed on the disassembly and assembly device both at the maximum diameter and the minimum diameter, and will not cause the center line to shift and cannot ensure that the bearing hole of the bearing seat corresponds to the axis of the vertical roll 3 on the same left and right center line, and will not block the disassembly and assembly of the bearing seat.
