Description

Technical Field

[0001] The utility model relates to the technical field of rolling mills, in particular to a support roller replacement device. Background Art

[0002] A rolling mill is a machine used for metalworking. It compresses the cross-sectional area of a metal billet to make it more uniform and compact. Based on the mill's motion, rolling mills can be divided into two main categories: one uses the oscillating work rolls to achieve rolling, known as swing roll mills; the other uses the synchronous rotation of two work rolls, known as tandem mills. Rolling mills are widely used, particularly in the steel and other metal manufacturing industries.

[0003] The main components of a rolling mill include rolls, roll supports, roll adjustment mechanisms, and transmission mechanisms. Rolls are the most core components, and their surfaces must be smooth and clean to ensure the smoothness and precision of the rolled metal. Furthermore, after a period of use, the support rolls of a rolling mill need to be replaced and overhauled. When replacing existing support rolls, the roll-changing platform needs to be hoisted with hooks. This means hooking the four hook holes at the corners of the roll-changing platform before hoisting. Figure 7 In order to prevent the roller changing platform from tilting or the hook from falling off the roller changing platform, multiple workers are required to manually hold the hook, which is not only labor-intensive and time-consuming, but also poses certain safety risks and reduces the efficiency of supporting roller replacement.

[0004] Therefore, it is urgent to redesign a new support roller replacement device to solve the above problems. Utility Model Content

[0005] The utility model provides a supporting roller replacement device to solve the technical problems raised in the above background technology.

[0006] The utility model provides a support roller replacement device, which includes a roller replacement platform and a plurality of anchor hooks;

[0007] The roller changing platform is provided with a plurality of hook holes and engaging grooves, and the hook holes are connected with the engaging grooves;

[0008] Several anchor-type hooks are respectively connected to the engaging grooves. The anchor-type hooks include a vertical connecting rod. The vertical connecting rod is fixedly connected with a lifting ring, a horizontal load-bearing member and a horizontal shift rod. The horizontal shift rod is arranged between the lifting ring and the horizontal load-bearing member. The roller changing platform is engaged between the horizontal load-bearing member and the horizontal shift rod. A pair of anti-rotation mechanisms are symmetrically installed on the horizontal shift rod.

[0009] Optionally, there are four hook holes, which are respectively arranged at the four corners of the roller changing platform. By installing the anchor hooks in the engaging grooves, the roller changing platform can be lifted smoothly to replace the support rollers.

[0010] Optionally, the diameter of the hook hole is larger than the diameter of the horizontal load-bearing member, so as to facilitate the horizontal load-bearing member to pass through the hook hole;

[0011] The width of the engaging groove is greater than the diameter of the vertical connecting rod and less than the length of the horizontal lever. Before lifting the roller changing platform, place the vertical connecting rod in the engaging groove and then rotate the horizontal lever 90° to engage the roller changing platform between the horizontal load-bearing member and the horizontal lever. The roller changing platform can be lifted steadily without the need for multiple workers to hold the anchor hooks by hand, which not only reduces the burden on the workers, but also ensures their safety and improves the subsequent replacement efficiency of the support rollers.

[0012] Optionally, the vertical connecting rod, the lifting ring, the horizontal load-bearing member and the horizontal lever are integrally formed to ensure the overall strength of the anchor hook.

[0013] Optionally, the anti-rotation mechanism includes an anti-rotation rod, which is slidably connected to the horizontal lever, and one end of the anti-rotation rod passes through the horizontal lever. When the horizontal lever rotates 90°, the anti-rotation rod contacts the top surface of the roller changing platform, making it difficult for the horizontal lever to rotate in the engaging groove, thereby ensuring the stability of the roller changing platform when lifting;

[0014] A pair of first limiting grooves are provided in the horizontal shift rod, the pair of first limiting grooves respectively corresponding to the pair of anti-rotation rods, and the first limiting grooves are used to accommodate the limiting ring and the first spring.

[0015] Optionally, the anti-rotation rod is located on the side wall of the first limit groove and is connected to a limit ring. A first spring is provided in the first limit groove. The first spring is provided on the outside of the anti-rotation rod and corresponds to the limit ring, so that one end of the anti-rotation rod protrudes from the horizontal gear rod in a natural state. When the roller exchange platform is lifted, the anchor hook is not easy to rotate in the engaging groove.

[0016] Optionally, a movable groove is provided at one end of the anti-rotation rod close to the horizontal load-bearing member, and a reinforcement rod is slidably connected in the movable groove. The reinforcement rod can increase the contact effect between the anti-rotation rod and the top surface of the roller changing platform, further reducing the probability of rotation of the anchor hook.

[0017] Optionally, a second limiting groove is provided on the anti-rotation rod, the second limiting groove is connected to the movable groove, the side wall of the reinforcement rod is fixedly connected to the limiting rod, and the limiting rod is provided in the second limiting groove. By sliding the limiting rod in the second limiting groove, the reinforcement rod can be limited, so that the reinforcement rod is not easy to slide out of the anti-rotation rod completely.

[0018] Optionally, an anti-slip rod is fixedly connected to the reinforcement rod, and the anti-rotation rod is provided with an avoidance groove matching the anti-slip rod, and the avoidance groove is connected to the movable groove. The setting of the anti-slip rod facilitates the installation of the second spring, making it difficult for the second spring to separate from the movable groove.

[0019] Optionally, a second spring is provided in the movable groove, and the second spring is provided on the outside of the anti-slip rod and between the reinforcement rod and the side wall of the movable groove. The second spring is used to apply force to the reinforcement rod so that the reinforcement rod protrudes from the anti-rotation rod in a natural state, which is used to increase the contact effect between the anti-rotation rod and the top surface of the roller changing platform, and reduce the probability of the anchor hook rotating in the engaging groove.

[0020] The beneficial effects of the utility model are as follows:

[0021] This type of support roller replacement device can reduce the manual hand-held hooks through the setting of corresponding mechanisms, thereby reducing the burden on workers and ensuring their safety, while also improving the replacement efficiency of support rollers.

[0031] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0032] See also Figures 1 to 6 A support roller replacement device of the present invention includes a roller replacement platform 1 and a plurality of anchor hooks 2.

[0033] The roller changing platform 1 is used to support the support rollers and is provided with a plurality of hook holes 101 and engaging slots 102. The hook holes 101 communicate with the engaging slots 102. The hook holes 101 facilitate the horizontal load-bearing member 203 to pass through the roller changing platform 1, so that the vertical connecting rod 201 can engage with the engaging slots 102, thereby fixing the roller changing platform 1 between the horizontal load-bearing member 203 and the horizontal lever 204, and facilitating subsequent lifting of the roller changing platform 1.

[0034] Preferably, there are four hook holes 101, which are respectively provided at the four corners of the roller changing platform 1. By installing the anchor hook 2 in the engaging groove 102, the subsequent stable lifting of the roller changing platform 1 can be achieved, thereby facilitating the replacement of the support roller.

[0035] In addition, the diameter of the hook hole 101 is larger than the diameter of the horizontal load-bearing member 203, which facilitates the horizontal load-bearing member 203 to pass through the roller changing platform 1, so that the vertical connecting rod 201 enters the engaging groove 102 and engages the roller changing platform 1 between the horizontal load-bearing member 203 and the horizontal gear rod 204.

[0036] Specifically, the width of the engaging groove 102 is greater than the diameter of the vertical connecting rod 201 and less than the length of the horizontal lever 204. Before lifting the roller changing platform 1, the vertical connecting rod 201 is placed in the engaging groove 102, and the horizontal lever 204 is rotated 90 degrees. This allows the roller changing platform 1 to be engaged between the horizontal load-bearing member 203 and the horizontal lever 204. This eliminates the need for multiple workers to manually hold the anchor hook 2, allowing the roller changing platform 1 to be lifted smoothly. This not only reduces the burden on workers, but also ensures their safety and improves the efficiency of subsequent replacement of support rollers.

[0037] See also Figures 1 to 6 , several anchor hooks 2 are respectively connected to the engaging grooves 102. When the anchor hooks 2 are installed on the roller changing platform 1, the roller changing platform 1 can be lifted steadily without the need for multiple workers to hold it by hand, which not only reduces the burden on the workers, but also ensures the safety of the workers, and also improves the subsequent replacement efficiency of the support rollers.

[0038] The anchor hook 2 includes a vertical connecting rod 201, to which a lifting ring 202, a horizontal load-bearing member 203, and a horizontal shift rod 204 are fixedly connected. The horizontal shift rod 204 is disposed between the lifting ring 202 and the horizontal load-bearing member 203, and the roller changing platform 1 is engaged between the horizontal load-bearing member 203 and the horizontal shift rod 204. The vertical connecting rod 201, the lifting ring 202, the horizontal load-bearing member 203, and the horizontal shift rod 204 are integrally formed to ensure the overall strength of the anchor hook 2.

[0039] See also Figures 1 to 6 A pair of anti-rotation mechanisms are symmetrically installed on the horizontal lever 204. Through the setting of the anti-rotation mechanism, when the vertical connecting rod 201 is engaged in the engaging groove 102, the anchor hook 2 is not easy to rotate, thereby ensuring the fixing effect of the anchor hook 2 and the roller changing platform 1, so that the roller changing platform 1 can be lifted smoothly later.

[0040] The anti-rotation mechanism includes an anti-rotation rod 205, which is slidably connected to the horizontal lever 204, and one end of the anti-rotation rod 205 passes through the horizontal lever 204. When the horizontal lever 204 rotates 90 degrees, the anti-rotation rod 205 contacts the top surface of the roller changing platform 1, making it difficult for the horizontal lever 204 to rotate in the engaging groove 102, thereby ensuring the stability of the roller changing platform 1 during lifting.

[0041] In addition, a pair of first limiting grooves 206 are provided in the horizontal lever 204 . The pair of first limiting grooves 206 respectively correspond to the pair of anti-rotation rods 205 . The first limiting grooves 206 are used to accommodate the limiting ring 207 and the first spring 208 .

[0042] Specifically, the anti-rotation rod 205 is located at the side wall of the first limiting groove 206 and is connected to the limiting ring 207. A first spring 208 is provided in the first limiting groove 206. The first spring 208 is provided on the outside of the anti-rotation rod 205 and corresponds to the limiting ring 207, so that one end of the anti-rotation rod 205 protrudes from the horizontal lever 204 in a natural state, that is, Figure 3 When the roller-changing platform 1 is lifted, the anchor hook 2 is not easy to rotate in the engaging groove 102 .

[0043] See also Figures 1 to 6 The anti-rotation rod 205 is provided with a movable groove 209 at one end close to the horizontal load-bearing member 203, and a reinforcement rod 210 is slidably connected in the movable groove 209. The reinforcement rod 210 can increase the contact effect between the anti-rotation rod 205 and the top surface of the roller changing platform 1, further reducing the probability of the anchor hook 2 rotating.

[0044] The anti-rotation rod 205 is provided with a second limiting groove 211 extending therethrough, and the second limiting groove 211 is communicated with the movable groove 209. A limiting rod 212 is fixedly connected to the side wall of the reinforcement rod 210, and the limiting rod 212 is disposed in the second limiting groove 211. The limiting rod 212 slides in the second limiting groove 211, thereby limiting the reinforcement rod 210 and preventing it from completely sliding out of the anti-rotation rod 205.

[0045] In addition, an anti-slip rod 213 is fixedly connected to the reinforcement rod 210, and a position-avoiding groove 214 matching the anti-slip rod 213 is provided on the anti-rotation rod 205. The position-avoiding groove 214 is connected to the movable groove 209. The provision of the anti-slip rod 213 facilitates the installation of the second spring 215, making it difficult for the second spring 215 to escape from the movable groove 209.

[0046] Specifically, a second spring 215 is disposed within the movable groove 209. The second spring 215 is disposed outside the anti-slip rod 213 and between the reinforcement rod 210 and the sidewall of the movable groove 209. The second spring 215 is used to apply a force to the reinforcement rod 210, causing the reinforcement rod 210 to naturally protrude beyond the anti-rotation rod 205. This serves to increase the contact between the anti-rotation rod 205 and the top surface of the roller-changing platform 1, thereby reducing the probability of the anchor hook 2 rotating inwardly within the engaging groove 102.

[0047] During specific use, the horizontal load-bearing member 203 is passed through the hook hole 101 so that the horizontal load-bearing member 203 is located at the lower side of the roller changing platform 1, and then a pair of anti-rotation rods 205 are pulled to make the anti-rotation rods 205 and the horizontal gear rods 204 slide relative to each other, and the vertical connecting rod 201 is moved into the engaging groove 102. At this time, the roller changing platform 1 is arranged between the horizontal load-bearing member 203 and the horizontal gear rod 204.

[0048] Rotate the horizontal lever 204 90° and release the anti-rotation lever 205. The anti-rotation lever 205, under the cooperative action of the limiting ring 207 and the first spring 208, contacts the top surface of the roller-changing platform 1. Simultaneously, the reinforcing rod 210, under the action of the second spring 215, also contacts the top surface of the roller-changing platform 1, further increasing the friction effect. This prevents the horizontal lever 204 from rotating relative to the horizontal lever when in the engaging groove 102, thereby ensuring the subsequent lifting stability of the roller-changing platform 1. The anchor hook 2 of the present application does not require multiple staff members to manually support it during installation and use, which not only reduces the burden on the staff and ensures their safety, but also improves the efficiency of the support rollers, thereby improving the efficiency of subsequent support roller replacement.

[0049] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
