Description

Technical Field

[0001] The utility model relates to the technical field of rolling mill auxiliary equipment, in particular to a vertical roller rolling mill guide installation device. Background Art

[0002] The production lines of steel rolling mills are mostly arranged in a horizontal and vertical alternating manner. For the vertical rolling mill, since the foundation of the mill reducer is directly above the rolling mill, a blind area for hoisting is formed under the foundation of the vertical rolling mill reducer, resulting in the crane hook being unable to approach the vertical rolling stand when replacing the guide guard. When the guide guard of the vertical rolling mill needs to be replaced, the mill must be removed and installed offline; at the same time, since the guide guard of the vertical rolling mill is large in size and heavy in weight, it is difficult to maintain balance, and it takes a long time to completely manually hoist it, which affects production.

[0003] To solve the above problems, Chinese patent document CN 220862357 U (application number 202321863458.0) discloses a device for replacing the guide of a vertical roller rolling mill for bars and wires, including a positioning plate, a counterweight, a hook and a handheld balance bar. During use, the handheld balance bar needs to be directly operated by an operator. The guide device and the positioning plate with the counterweight are both extremely heavy, so there is a great safety hazard in the use of the device.

[0004] Therefore, it is necessary to provide a device that is easy to install and replace the guides of the vertical roller mill without direct contact with personnel, so as to improve the working efficiency on the basis of ensuring construction safety. Utility Model Content

By setting a guide and guard hook, no operator operation is required, thereby ensuring construction safety and being able to bypass obstacles such as the rolling mill arch to achieve accurate movement of the guide and guard.

[0006] In order to achieve the above technical effects, the utility model adopts the following technical solutions:

[0007] A vertical roller mill guide installation device comprises a moving assembly and a guide hook, wherein the moving assembly is used to drive the guide hook to move in the horizontal direction and the vertical direction.

[0008] The guide hook comprises a first transverse portion, a vertical portion and a second transverse portion which are connected as one body, the first transverse portion is provided with a hoisting station connected to the moving assembly, the second transverse portion is located below the first transverse portion, and the second transverse portion extends outside the vertical projection area of ​​the first transverse portion;

[0009] The moving assembly includes a fixed guide rail, a moving guide rail and an electric hoist. The top surface of the fixed guide rail is provided with a first electric slide rail, the bottom surface of the moving guide rail is provided with a first slider matching the first electric slide rail, and the top surface of the moving guide rail is provided with a second electric slide rail. The electric hoist is slidably arranged on the moving guide rail through the second slider matching the second electric slide rail. The extension direction of the first electric slide rail and the extension direction of the second electric slide rail are perpendicular to each other. The electric hoist is connected to the guide hook through a hoisting station.

[0010] The utility model provides a vertical roller rolling mill guide and guard installation device. By setting the guide and guard hook, the operator only needs to control the various electric control components in the moving component, drive the guide and guard hook through the lifting station, and make the second transverse part extend into the guide and guard. The setting of the vertical part enables the guide and guard hook to avoid the obstruction caused by the existing vertical roller rolling mill structure, thereby realizing efficient lifting of the guide and guard on the basis of ensuring safety.

[0011] Preferably, the first transverse portion is provided with a plurality of lifting positions. Before using the device, the operator can select different lifting positions according to the specific weight of different guides, so that the guide hook is always in a balanced state.

[0012] Preferably, the fixed rails are provided with two parallel fixed rails, and the fixed rails are respectively provided at both ends of the movable rail, and a fixed rail connecting frame is provided between the two fixed rails. By providing fixed rails at both ends of the movable rails, the load-bearing capacity of the movable assembly is further improved to ensure safe operation.

[0013] Preferably, the two fixed guide rails are respectively fixed on the arch base and the reducer platform of the vertical roller mill.
