Description
Technical Field
[0001] The utility model belongs to the field of steel rolling, and in particular relates to a sliding anti-collision heat-insulating cover device. Background Art
[0002] At present, the rolling line in the rough rolling area of conventional hot rolling production lines is long, and the temperature drop of slabs is large. To improve this situation, some production lines install insulation covers between two rough rolling mills. To improve the insulation effect, the insulation cover is close to the rolling mill and installed between the side guides of the two rolling mills. The height difference between the insulation cover and the roller is 300-700mm. If the height is too large, the insulation effect is not good. If the height is too small, not only the rolling specifications and varieties are limited, but also it is easy to be hit frequently, affecting the normal rolling. At the same time, it causes great damage to the upper cover and even the main body of the insulation cover. In severe cases, it will cause steel jamming accidents, causing huge losses to production and equipment costs. Normal intermediate billets can enter the insulation cover smoothly. Once the intermediate billet tilts, it will hit the insulation cover, affecting the stability of rolling.
[0003] In the prior art, patent application number: CN202111667161.2, discloses an insulation cover anti-collision buffer device, which suspends the slab at the transmission end between the rough rolling outlet and the insulation cover, reasonably adjusts the buffer inclination angle to ensure that the lowest point is lower than the height of the insulation cotton, and uses the warped head to hit the slab to change the height at which the head enters the insulation cover. The overall structure of the device is relatively complex, and it is installed in a suspended manner, which makes installation more difficult. There is a certain distance between the device and the insulation cover, and determining the lowest point of the slab requires a certain amount of measurement work, which increases the difficulty of installation. Summary of the invention
[0004] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a sliding anti-collision insulation cover device to prevent the heat preservation cover from being hit by the warping of the intermediate billet during rough rolling, reduce damage to the insulation cover, avoid equipment damage and accidents, ensure the insulation effect of the insulation cover, prevent heat loss, and improve rolling stability.
[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:
[0006] A sliding anti-collision heat-insulating cover device comprises a cover body, a frame, and an upper crossbeam. The upper crossbeam is fixed on the top of the frame. The cover body is connected to the upper crossbeam by a hinge. It also comprises an iron chain, a protection plate, an anti-impact slide plate, a slide plate slideway, and a reset spring. The end of the protection plate is hinged to the cover body, one end of the iron chain is fixedly connected to the upper crossbeam, and the other end is connected to the protection plate. The slide plate slideway is fixedly connected to the upper crossbeam, the anti-impact slide plate is slidably connected to the slide plate slideway, one end of the anti-impact slide plate can contact the protection plate, and the other end is connected to the reset spring. The reset spring is fixedly connected to the upper crossbeam.
[0007] It also includes a connecting shaft, which is fixedly connected to the cover body, and the protection plate and the cover body are hinged through the connecting shaft.
[0008] An anti-collision steel beam is fixedly connected to the top of the cover body.
[0009] The anti-collision steel beam is higher than the lowest point of the protection plate.
[0010] The protection plate is a flat plate or an arc-shaped steel plate.
[0011] The radius of the arc-shaped steel plate is 500-1000 mm.
[0012] The protection plate and the upper cross beam are both fixedly connected with fixing rings, and the two ends of the iron chain are respectively connected with the protection plate and the upper cross beam through the fixing rings.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The sliding anti-collision heat preservation cover device has a reasonable structure and is suitable for use in the actual on-site environment, so as to avoid damage to the heat preservation cover due to the excessive tilt of the intermediate billet. The crossbeam on the heat preservation cover uses an iron chain to hang the protection plate obliquely, so that the lowest point of the protection plate is lower than the lower surface of the heat preservation cover body. Once the tilt of the intermediate billet hits the protection plate, the protection plate rotates upward with the connecting shaft as the axis, and the anti-impact slide plate compresses the reset spring by sliding.

[0019] The present invention is described in detail below in conjunction with the accompanying drawings of the specification, but it should be noted that the implementation of the present invention is not limited to the following embodiments.
[0020] Example 1
[0021] See Figure 1-Figure 3A sliding anti-collision heat preservation cover device comprises a cover body 2, a frame 1, an upper crossbeam 4, an iron chain 6, a protection plate 7, an anti-impact slide plate 10, a slide plate slideway 11, and a reset spring 13. The upper crossbeam 4 is fixed to the top of the frame 1, and the frame 1 is fixed to the foundation on both sides of the roller 3. A hinge is fixed at the lower part of the upper crossbeam 4 for hanging the cover body 2. The cover body 2 is arranged above the roller 3. The end of the protection plate 7 is hinged to the cover body 2. One end of the iron chain 6 is fixedly connected to the upper crossbeam 4, and the other end is connected to the protection plate 7. The slide plate slideway 11 is fixedly connected to the upper crossbeam 4. The anti-impact slide plate 10 is slidably connected to the slide plate slideway 11. One end of the anti-impact slide plate 10 can contact the protection plate 7, and the other end is connected to the reset spring 13. The reset spring 13 is fixedly connected to the upper crossbeam 4.
[0022] Example 2
[0023] On the basis of Example 1, the sliding anti-collision heat preservation cover device further includes a connecting shaft 8, which is welded and fixed on the cover body 2, and the protection plate 7 is hinged to the cover body 2 through the connecting shaft 8, so that the protection plate 7 can rotate around the connecting shaft 8. An anti-collision steel beam is fixedly connected to the top of the cover body 2, and the anti-collision steel beam can be arranged on both sides of the protection plate 7 to further prevent the intermediate blank from damaging the cover body 2. The anti-collision steel beam is higher than the lowest point of the protection plate 7, and the height difference between the two is a=30-80mm.
[0024] In addition, the protective plate 7 can be a flat plate structure made of steel plate, and the protective plate 7 can also be an arc-shaped steel plate. In the actual production process, the arc-shaped steel plate is better than the protective plate 7 with a flat plate structure, and the radius of the arc-shaped steel plate is 500-1000mm. The upper half of the protective plate 7 and the upper crossbeam 4 are fixedly connected with a fixing ring 5, and the two ends of the iron chain 6 are respectively connected to the protective plate 7 and the upper crossbeam 4 through the fixing ring 5. The use of an arc-shaped steel plate for the protective plate 7 can reduce the impact force of the warping head. Since the intermediate blank is in line contact with the arc-shaped steel plate after the warping head, the arc-shaped steel plate is subjected to little force. After the protective plate 7 is subjected to force, it rotates upward and reduces part of the impact force, so that the damage to the protective plate 7 is very small; in addition, the protective plate 7 plays the role of guiding the intermediate blank into the heat preservation cover. After the intermediate blank warps and hits the protective plate 7, it can smoothly enter the heat preservation cover along the arc line at the lower end of the protective plate 7 without hitting the heat preservation cover 2, so that the heat preservation cover 2 is not damaged.
[0025] When the head of the intermediate billet is higher than the allowable height 9, it hits the protection plate 7. After the protection plate 7 is stressed, it is lifted up around the connecting shaft 8, and the anti-impact slide plate 10 slides to the right on the slide slideway 11. When the protective steel plate is not stressed, the anti-impact slide plate 10 slides to the left under the action of the reset spring 13 and returns to its original state under the restriction of the iron chain 6. Because the temperature of the head of the intermediate billet is high, it is easy to produce plastic deformation, and the thickness and weight of the intermediate billet are large. After the head is hit by the protection plate 7, the angle between the head and the intermediate billet is adjusted to a height that can enter the insulation cover, so that the intermediate billet can smoothly enter the insulation cover body without damaging the insulation cover.
[0026] The utility model has a reasonable structure. The crossbeam 4 on the heat preservation cover adopts an iron chain 6 to obliquely hang the protection plate 7, so that the lowest point of the protection plate 7 is lower than the lower surface of the heat preservation cover body 2, and the height difference between the two is a. Figure 3 Once the warped head of the intermediate billet hits the protection plate 7, the protection plate 7 rotates upward with the connecting shaft 8 as the axis, and the anti-impact slide plate 10 compresses the reset spring 13 by sliding, and the iron chain 6 and the anti-impact slide plate 10 can absorb part of the impact, reduce damage to the insulation cover, avoid equipment damage and accidents, ensure the insulation effect of the insulation cover, prevent heat loss, and improve rolling stability.
