Description

Technical Field

[0001] The utility model relates to a surface polishing device for a building steel structure, belonging to the technical field of building steel structures. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structure is easy to rust. Generally, steel structure needs to be rust-proofed, galvanized or painted, and regular maintenance is required.

[0003] The existing patent number is CN214603718U, which is a surface polishing device for building steel structures. The device places the building steel on the top of the base, starts the first hydraulic cylinder to drive the driving rack to descend, the driving rack drives two driving gears to rotate, the driving gear drives the rotating plate to rotate, the rotating plate pulls the two sliding rods and the clamping plate closer to each other, the clamping plate drives the rollers to fit on both sides of the building steel and clamp them, then starts the second hydraulic cylinder to drive the mounting seat to descend according to the height of the steel, so that the polishing wheel and the top of the steel fit together, starts the driving motor to drive the driving bevel gear to rotate, the driving bevel gear drives the bevel gear to rotate, and the bevel gear drives the driving The shaft rotates, and the driving shaft drives the polishing wheel to polish the surface of the steel. Although this device can position and clamp the steel structure when in use, it also imposes certain restrictions on the steel structure, making it difficult to automatically transport the steel structure and requiring manual pushing. However, this easily causes wear to the bottom, which is not conducive to the automatic grinding and feeding of the steel structure. Moreover, in the process of grinding the steel structure, only one side can be ground, and the angle cannot be converted after single-side grinding, so that the device needs to repeatedly clamp and push a single steel structure, making it time-consuming and labor-intensive to polish multiple sides of the steel structure, reducing the convenience of the overall polishing of the steel structure.
