[0002] The descaling machine is composed of several upper and lower rows of roll systems installed in roll boxes. As one of the conventional equipment on the rolling, annealing, pickling, and stainless steel production line, the working rolls need to be periodically replaced due to the wear of the roll surface after every 10,000 tons of production.

[0003] As one of the conventional equipment on the rolling, annealing, pickling, and stainless steel production line, as the service time of the descaling machine becomes longer, the roll group inside it will be worn, affecting the subsequent working efficiency. Therefore, it is necessary to regularly replace the roll group, and a corresponding roll-changing vehicle is required for the replacement. However, when using the existing roll-changing vehicle for the descaling machine roll group, in the face of the descaling machine roll groups installed at different positions and heights, there is a lack of adjustment of the working height of the roll-changing vehicle, which is not convenient for replacing the roll group. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] A roll-changing vehicle for a descaling machine roll group includes a roll-changing vehicle frame 1 and a roll-changing vehicle base 2. The surface of the roll-changing vehicle base 2 is threadedly sleeved with a threaded rod 3, and the lifting of the roll-changing vehicle frame 1 is controlled by rotation. The surface of the threaded rod 3 is fixedly connected with a first gear 4, and the rotation of the threaded rod 3 is driven by rotation. The surface of the threaded rod 3 is fixedly connected with a limit disc 5 to limit the position of the threaded rod 3. The surface of the first gear 4 is rotatably connected with a second gear 6 for driving the first gear 4 to rotate. The surface of the second gear 6 is fixedly connected with a rotating handle 7 for rotating the second gear 6. The surface of the roll-changing vehicle frame 1 is fixedly connected with a fixed sleeve 8 for the threaded rod 3 to rotate. The surface of the roll-changing vehicle frame 1 is provided with a placing groove 9 for placing the support rod 11. The inside of the placing groove 9 is fixedly connected with a first connecting rod 10 to ensure that the support rod 11 can rotate. The surface of the first connecting rod 10 is rotatably connected with a support rod 11 for inserting into the insertion slot 15 to support the limit plate 14. The surface of the roll-changing vehicle frame 1 is fixedly connected with a fixed plate 12 for connecting the second connecting rod 13. The surface of the fixed plate 12 is fixedly connected with a second connecting rod 13 to ensure that the limit plate 14 can rotate. The surface of the second connecting rod 13 is rotatably connected with a limit plate 14 for protecting the roll placed on the surface of the roll-changing vehicle frame 1 to prevent it from rolling off the surface of the roll-changing vehicle frame 1. The surface of the limit plate 14 is provided with an insertion slot 15 for inserting the support rod 11.

[0024] Furthermore, the second gear 6 is rotationally connected to the inside of the speed controller 7 and the roll-changing cart base 2. The first gear 4 is rotationally connected to the inside of the roll-changing cart base 2 through the second gear 6. Rotating the speed controller 7 drives the second gear 6 to rotate, thereby driving the first gear 4 to rotate inside the roll-changing cart base 2.

[0025] Furthermore, the threaded rod 3 is rotationally connected to the surface of the roll-changing cart base 2 through the first gear 4. Rotating the first gear 4 drives the threaded rod 3 to rotate. The limiting disc 5 is rotationally connected to the inside of the roll-changing cart base 2 through the threaded rod 3. The diameter of the limiting disc 5 is larger than that of the threaded rod 3. The setting of the limiting disc 5 enables the threaded rod 3 not to change its position while rotating.

[0026] Furthermore, the threaded rod 3 is threadedly sleeved inside the fixed sleeve 8. The roll-changing cart frame 1 is movably connected to the surface of the roll-changing cart base 2 through the threaded rod 3. When the roll-changing cart base 2 rotates, the limiting disc 5 keeps the position of the roll-changing cart base 2 unchanged. Thereby, the roll-changing cart frame 1 moves on the surface of the threaded rod 3 to adjust the height of the roll-changing cart frame 1 for better removal and replacement of the roll set in the descaling machine.

[0027] Furthermore, the support rod 11 consists of two parts. One part of the support rod 11 is cylindrically sleeved on the surface of the first connecting rod 10 to ensure that the support rod 11 can rotate. The other part of the support rod 11 is rod-shaped and is used to be inserted into the surface of the slot 15. The support rod 11 is rotationally connected to the surface of the roll-changing cart frame 1 through the first connecting rod 10. Rotating the support rod 11 can insert the support rod 11 into the surface of the slot 15 to support the limiting plate 14, or it can be placed inside the placement groove 9 for storage.

[0028] Furthermore, the fixing plates 12 are symmetrically distributed in two groups on the surface of the second connecting rod 13. The limiting plate 14 is rotationally connected to the surface of the roll-changing cart frame 1 through the second connecting rod 13. According to the size of the roll set in the descaling machine, the limiting plate 14 can be rotated so that it can protect the roll placed on the surface of the roll-changing cart frame 1 and prevent it from falling.

[0029] Furthermore, the slots 15 are evenly opened on the surface of the limiting plate 14. The limiting plate 14 is in abutting connection with the surface of the support rod 11 through the slots 15. By inserting the support rod 11 into the slots 15 at different positions, the limiting plate 14 can be made to have different inclination angles to adapt to roll sets of different specifications and improve the protection of the roll placed on the surface of the roll-changing cart frame 1.

[0030] Working principle: When using the roll-changing carriage 1, first move the roll-changing vehicle base 2 to the side of the descaling machine where the roll set needs to be replaced. According to the distance between the surface of the roll-changing carriage 1 and the roll set, rotate the handle 7 to drive the second gear 6 to rotate, thereby driving the first gear 4 and the threaded rod 3 to rotate. The setting of the limit disc 5 ensures that the position of the threaded rod 3 does not change, so as to adjust the height of the roll-changing carriage 1. When the roll-changing carriage 1 is adjusted to the appropriate height, start the roll-changing carriage 1. The roll-changing carriage 1 automatically removes the roll set in the descaling machine. Then, according to the specifications of the roll set, rotate the limit plate 14 and make the limit plate 14 as close as possible to the surface of the roll. Then, rotate the support rod 11 out of the placement groove 9 and insert the support rod 11 into the slot 15 at the appropriate position to support the limit plate 14 and limit and protect the roll placed on the surface of the roll-changing carriage 1. After removing the roll set to be replaced and moving it to the appropriate position, bring a new roll set, and then install it into the descaling machine through the roll-changing carriage 1 to complete the replacement of the roll set of the descaling machine. Then, rotate the support rod 11 and put it back into the placement groove 9, rotate the limit plate 14 to make it fit the surface of the roll-changing carriage 1 for storage, and rotate the handle 7 to make the roll-changing carriage 1 fall back to the surface of the roll-changing vehicle base 2.
