Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling mills, in particular to a novel working roll changing device for a cold rolling mill. Background Art

[0002] During the use of the cold rolling mill, the working rolls often need to be inspected and repaired. If the working rolls are offset or damaged, they need to be repaired or replaced in time. Due to the long length and heavy weight of the working rolls, a crane is often used to assist in the disassembly and installation of the working rolls during operation. However, since the working rolls are cylindrical, multiple straps need to be used to fix them when they are lifted by the crane. If you are not careful, the working rolls will slip off one end of the straps. In addition, since the working rolls need to be installed on the bearing boxes on both sides, the installation process takes a long time, so the crane needs to keep working for a long time to facilitate the installation of the working rolls. During the installation process, the working rolls need to adjust their posture so that they are installed with the bearings facing upward. However, the rising and falling distances of the crane are large and difficult to control when it is inched. During the installation process, the working rolls can only be debugged for a long time and adjusted manually, which makes the work intensity greater and has certain risks. In this regard, the present technical solution is specially proposed for improvement. Utility Model Content

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0017] See also Figures 1 to 3 The embodiment of the utility model discloses a novel cold rolling mill working roll changing device, comprising a stable base 1, at the bottom of which wheels 101 for easy movement are installed, the wheels 101 are directional wheels, so that the base 1 can only move along the rotation direction of the wheels 101, to ensure the control effect of the moving direction, to ensure stability, so that the entire device can be stably maintained at a specified position, a track 102 is laid along the length direction of the base 1 above the base 1, the length direction of the track 102 is perpendicular to the rotation direction of the wheels 101, and a support base 2 is firmly slidably connected to the track 102, this design not only ensures the stability of the support base 2 during movement, but also the moving directions of the support base 2 and the base 1 are perpendicular to each other, so that the operator can easily adjust its position according to the needs of use to adapt to the needs of different working environments.

[0018] A lifting device is arranged above the support seat 2. The adjusting rod in the center of the support seat 2 uses a worm gear 203 structure as the core component of the adjusting rod. This structure not only has a self-locking function and can remain stable at any position, but also facilitates the operator to use a wrench for precise adjustment through the design of the side connector. The specially arranged limit convex ridges on the connector are engaged with the wrench to prevent the wrench from accidentally sliding during the adjustment process, thereby ensuring the safety of the operation. A sleeve 201 is installed at the four corners of the support seat 2. Four slide bars 202 are arranged at the four corners of the top plate 3 above the support seat 2. The slide bars 202 are slidably arranged inside the sleeve 201. The bottom of the slide bars 202 and the adjusting rod protrude from the bottom of the support seat 2, providing space for the slide bars 202 and the adjusting rod when the top plate 3 is lifted up and down. The lifting of the support seat 2 is adjusted by the worm gear. The slide bars 202 ensure stability and improve safety during use. As the adjusting rod is lifted up and down, the top plate 3 also moves up and down, providing a stable platform for the hoisting and installation of the working roll.

[0019] A turntable 301 is provided on the upper part of the top plate 3, and a support plate 4 for supporting the roll to be replaced is installed on the surface of the turntable 301. The setting of the turntable 301 can make the working roll easily rotate 360 ​​degrees during the installation process, so as to easily adjust to the best installation posture, which greatly shortens the installation time and reduces the difficulty of operation.

[0020] A plurality of limit grooves facing the horizontal axis are provided on the upper surface of the support plate 4, and a limit block 401 is slidably installed inside the limit groove. A stop block 403 higher than the upper surface of the support plate 4 is provided on the top of the limit block 401, which is used to stop the side of the working roll to prevent it from shaking or sliding during installation. An adjusting bolt 402 is also provided on the side of the limit block 401, allowing the operator to make fine adjustments according to the actual size of the working roll to ensure the best fixing effect and improve the stability of the working roll during the replacement process. A positioning block 404 is provided in the middle position of the limit groove, and its top is designed to be arc-shaped. When replacing the working roll, a spare roll is placed on one side of the positioning block 404, and the replaced working roll can be placed on the other side of the positioning block 404. The limit blocks 401 and the stop block 403 on both sides maintain stability, which is convenient for improving the convenience and stability of the working roll during replacement. The arc-shaped top surface can facilitate the working roll or spare roll to enter the specified position, improve the use effect, greatly improve the work efficiency and safety, and reduce the labor intensity and safety risks of the operator.

[0021] When in use, the base 1 and the support seat 2 are moved perpendicularly to each other to meet the directional position requirements during the roll changing process. During the roll changing process, the direction of the working roll can be adjusted by rotating the support plate 4, and the up and down positions can be adjusted by the worm gear 203. The position of the working roll can be guaranteed for a long time and the adjustment is convenient. The contact area between the support plate 4 and the working roll is large to ensure stability, and the working roll can be supported for a long time, thereby reducing labor intensity and ensuring safe use.
