Description

Technical Field

[0001] The utility model relates to the technical field of strip steel production, in particular to a lifting device for a strip steel inspection system and a strip steel inspection system. Background Art

[0002] The inspection station is a key equipment for cold rolling. It is mainly used to horizontally tension the steel strip after unwinding it, and then grind it with a grindstone to facilitate manual inspection of the surface of the steel strip for defects. In some solutions of the prior art, the steel strip unwinding by the uncoiler is conveyed along the surface of the inspection platform and spread out for grinding inspection. However, in this solution, since the lower surface of the steel strip is in contact with the inspection platform, only the upper surface of the steel strip can be grinded and inspected. In addition, due to the length limitation of the inspection platform, the length of the steel strip that can be inspected is insufficient, which easily leads to the problem that surface defects cannot be fully discovered.

[0003] Patent CN210907462U discloses an off-line strip steel inspection device. During use, the steel coil is first placed in the uncoiler, and the upper pressure roller presses the steel coil from the top of the uncoiler to prevent the steel coil from loosening naturally. Then, the strip head of the steel strip on the steel coil is extended to a certain length to press and fix the strip head to the clamp provided at the lower side of the uncoiler. The uncoiler is started to transport the steel strip on the steel coil outward to unfold the steel strip. Since the strip head is clamped and fixed by the clamp provided at the lower side of the uncoiler, and the top of the steel coil is pressed by the upper pressure roller, the steel strip unfolded from the uncoiler will form a U-shaped structure, and the U-shaped strip will be laid flat on the inspection platform provided at the bottom of the uncoiler to inspect the steel strip. Although this solution can inspect the upper and lower surfaces of the strip, the inspection length is limited. Only the upper half of the U-shaped structure can be inspected, and the lower half of the U-shaped structure is still in contact with the inspection platform, making it difficult to inspect its lower surface. In addition, although this solution can increase the inspection length of the strip to 10 meters, the inspection length is still not enough. In some cases, the inspection length of the strip is required to be no less than 15 meters.

[0004] Based on this, the existing technology still needs to be improved. Utility Model Content

[0038] In the embodiment of the utility model, the two ends of the support roller 30 are respectively connected to the guide rails 22 of the two brackets 20 by sliding blocks 32, and the support roller 30 is driven by the driving mechanism to slide upward to lift the strip steel 1 to form an arch, so that a strip steel area separated from the inspection platform can be formed on the upstream and downstream sides of the support roller 30, which is convenient for the upper and lower surface inspection of the strip steel area, and the lifting height can be set to achieve a sufficient strip steel inspection length on a limited inspection platform (the higher the lifting height, the longer the strip steel inspection length that can be achieved), thereby ensuring a comprehensive inspection of the strip steel and reducing or avoiding missed inspection accidents. When in use, the support roller 30 can be driven to the lowest position first, at which time the transmitted strip steel 1 passes over the support roller 30 from above the support roller 30, and the support roller 30 is located below the strip steel 1, and then the support roller 30 is driven to rise to a high position, so that the support roller 30 lifts the strip steel 1 to form an arch.

[0039] In some embodiments, the driving mechanism includes two first hydraulic cylinders 40, and the piston rods of the two first hydraulic cylinders 40 are respectively connected to the two sliders 32. The sliders 32 are driven by the telescopic movement of the piston rods to drive the support rollers 30 to move up and down. Of course, in other embodiments, the driving can also be achieved by other driving mechanisms such as a screw nut matching mechanism, a gear rack matching mechanism, etc.

[0040] In some embodiments, the lifting device 100 further includes a movable beam 50 extending in the transverse direction and located above the support roller 30, and the two ends of the movable beam 50 are respectively slidably connected to the two guide rails 22; the lifting device 100 further includes two second hydraulic cylinders 42 disposed on the base 10, and the piston rods of the two second hydraulic cylinders 42 are respectively connected to the two ends of the movable beam 50 to drive the movable beam 50 to slide; the first hydraulic cylinder 40 is disposed on the movable beam 50.

By providing the vertical extension members 14, the transverse extension members 16, and the longitudinal extension members 18 staggered in three directions, the strength and stability of the support base 12 are improved.

[0042] In some embodiments, the height of the support base 12 is adjustable, and the lifting height of the support roller 30 can be increased by raising the support base 12 .

[0043] In some embodiments, each bracket 20 includes two parallel columns 24, and the surfaces of the two columns 24 facing each other are provided with guide rails 22, and both sides of the slider 32 and both sides of the end of the movable beam 50 are respectively slidably connected to the guide rails 22 of the two columns 24. Thus, the stability of the sliding process can be improved, and the slider 32 and the end of the movable beam 50 can be protected to a certain extent by being arranged between the two columns 24, and it is also conducive to achieving a compact structure.

[0044] In some embodiments, the lifting device 100 further includes a crossbeam 26 connecting the upper parts of the two brackets 20 to firmly connect the two brackets 20.

The introduction plate 60 is used to guide the strip 1 to be horizontally transferred to pass over the support roller 30.

[0046] In some embodiments, the lifting device 100 further includes an export plate 62 located on the downstream side of the support roller 30 in the running direction of the steel strip. The export plate 62 is connected between the lower parts of the two brackets 20 and tilted downward from the downstream end to the upstream end. The upper surface of the export plate 62 at the highest end is flush with the upper surface of the import plate 60. The upstream end of the export plate 62 tilts downward to be lower than the highest point of the support roller 30 to avoid obstruction to the transmission of the steel strip 1. The highest end of the export plate 62 is flush with the import plate 60, further guiding the steel strip 1 to be transmitted downstream. The import plate 60 and the export plate 62 are arranged at intervals.

The characteristics of the device are: small footprint, convenient for operators to grind the surface of the steel strip without dead angles, simple design, and strong operability. After the device is put into use, it will establish sufficient tension for the steel strip to facilitate operators to grind without dead angles, and it is easier to find defects in the steel strip. Since the debris on the surface of the inspection platform interferes with the identification of surface defects of the steel strip, this device allows the steel strip to be suspended from the inspection platform, which is more conducive to the discovery and identification of surface defects of the steel strip.
