Description

Technical Field

[0001] The utility model relates to the technical field of rust removal and protection, in particular to a rust removal and protection device for angle steel. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel strip with two sides perpendicular to each other. There are equal-leg angle steel and unequal-leg angle steel. Angle steel is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.

[0003] Traditional rust removal and protection technology often uses a rust removal device for angle steel, such as the one disclosed in announcement number CN108015659B. During the grinding process, rust dust will spread disorderly and affect the surrounding air quality. Therefore, under the existing technical conditions, sandblasting technology is mostly used to achieve rust removal operations. However, the existing sandblasting and rust removal equipment lacks supporting limiting and driving measures for angle steels, which requires more manual participation to ensure that the angle steels can be fully sandblasted. At the same time, because the angle steels are large in size, sandblasting operations over a large range can easily cause the diffusion of abrasive agents, which not only fails to ensure the uniformity and comprehensiveness of the sandblasting operation, but is also more likely to cause pollution and waste.

[0023] The fixing mechanism includes a transmission cross bar 8 matched with the output end of the telescopic cylinder 2, a first connecting rod 9 is connected to the main body 1 by a pin shaft, a sliding sleeve 10 connected to the first connecting rod 9 by a pin shaft is slidably installed on the transmission cross bar 8, a second connecting rod 11 is connected to the bottom pin shaft of the sliding sleeve 10, a sliding column 12 connected to the free end pin shaft of the second connecting rod 11 is slidably installed in the main body 1, and a clamping plate 13 fixedly connected to the sliding column 12 is slidably installed on the upper end of the main body 1. When the transmission cross bar 8 is pushed forward, the sliding sleeve 10 will slide outward, and the second connecting rod 11 will pull the sliding column 12 to slide inward, thereby controlling the clamping plate 13 to clamp the angle steel;

[0024] A second drive motor 14 is fixedly installed on one side of the splint 13, and a turntable 15 driven by the second drive motor 14 is rotatably installed on the splint 13. A placement groove 16 for placing angle steel is opened on the turntable 15, and the placement groove 16 is 90° to fit the angle of the angle steel. The angle steel is a steel material with two sides perpendicular to each other. The placement groove 16 is set to 90°, so that the angle steel fits better to the turntable 15 and the fixation is also made more secure.
