Polishing device for flange plate edge opening of steel structure H-shaped component

Abstract

The invention discloses a polishing device for a flange plate edge opening of a steel structure H-shaped component, and relates to the technical field of steel structure machining polishing. The polishing device for the flange plate edge opening of the steel structure H-shaped component comprises driving equipment. The driving equipment comprises lower travelling wheels, lower telescopic rod pieces and lateral sliding wheels. The number of the lower travelling wheels is two and the lower travelling wheels are arranged under the driving equipment left and right. The two lower travelling wheelsare in driving connection with the driving equipment through driving rods respectively. The number of the lower telescopic rod pieces is two and the lower telescopic rod pieces are horizontally fixedto the left side and the right side of the driving equipment separately. The number of the lateral sliding wheels is two and the lateral sliding wheels are connected to the tail ends of the two lowertelescopic rod pieces in a rotating mode correspondingly. A lifting shaft is vertically fixed to the middle of the upper portion of the driving equipment. The polishing device has the beneficial effects that the rounded corner effect of the steel plate edge opening can be guaranteed, coating materials can also have rounded corners, the specified valve meeting the coating requirement is met, the coating quality of the steel structure is ensured, the problem that the coating quality of the steel plate edge opening is poor in the prior art is solved and the service life of the steel component isprolonged.

Description

technical field [0001] The invention relates to the technical field of steel structure processing and grinding, in particular to a grinding device for the edge of a flange plate of an H-shaped member of a steel structure. Background technique [0002] The main material for the manufacture of steel structures is steel plates of various shapes, and after the steel plates are cut into various shapes, sharp angles will be left on the cut surface. When the structural anti-corrosion coating is applied, the specified coating thickness cannot be achieved, so corrosion will occur quickly, resulting in a sharp decline in the anti-corrosion ability of the entire steel component, seriously affecting the appearance of the steel component, and significantly shortening the service life of the steel component. In the prior art, a portable angular grinding wheel is used to grind the sharp corners of steel structural members to make the sharp corners blunt, but workers need to work in a dusty...
