At the same time, the grinding tool system is fixed on the drive system, and the drive system drives the grinding tool system to move in the horizontal or vertical direction to realize the adjustment of the grinding tool according to the position of the workpiece. Sharpening tool system, more practical.

The invention relates to a civil engineering I-steel column cross section derusting construction method. A rotating shaft sequentially passes through a calibration plate, a frame block a, a crawler disk, a top plate, a frame block b, and a displacement plate; slots are opened in the middle positions of tops of the frame block a and the frame block b; a through rod penetrates through a top plate block, and the two ends of the through rod are respectively placed in the slots of the frame block a and the frame block b; a base block is hinged to one end of a pull rod, and a ball rod is fixed in the middle of the pull rod; the ball end of the ball bar is in contact with the vertical end surface of the displacement plate. The invention adopts the linkage of the top plate, the displacement plateand the clamping member to realize the automatic derusting of the iron brush plate on the I-shaped section steel according to the predetermined trajectory; the iron brush plate can be divided into five kinds of technical means according to the degree of grinding fineness of the cross section of the I-steel, and the welding surface of different types of shapes is polished according to different welding requirements;in addition, the design of the product is simple in structure and easy for the construction personnel to get started.

The invention relates to a derusting construction method for the cross section of a constructional steel I-column. A rotary shaft penetrates through a calibration disc, a frame block a, a track disc,a top disc, a frame block b and a deflection disc in sequence, and slots are formed in the middles of the tops of the frame blocks a and b respectively; a through rod penetrates through a top plate block, and the two tail ends of the through rod are arranged in the slots of the frame blocks a and b respectively; a base block is hinged to one end of a pull rod, a ball screw is fixed to the middle of the pull rod, and the ball end of the ball screw abuts against the vertical end face of the deflection disc. According to the derusting construction method, through linkage of the top disc, the deflection disc and a clamping piece, an iron brush plate can automatically derust the i-section steel according to a preset locus; the technological means that iron brush plates can be classified into five specifications according to different I-steel section grinding fineness degrees is adopted, and it is achieved that welding faces in different shapes can be ground according to different welding requirements; besides, the designed product is simple in structure, and constructors easily get started.

The invention relates to a rust removal construction method for road I-shaped steel foundation. A rotating shaft sequentially penetrates through a calibration disc, a frame block a, a crawler disc, atop disc, a frame block b and a displacement disc; seam slots are formed in the middles of the tops of the frame block a and frame block b respectively, a through rod penetrates through a top plate block, and the two tail ends of the through rod are placed in the seam slots of the frame block a and frame block b respectively; a base block is hinged to one end of a pull rod, a rolling ball rod is fixed in the middle of the pull rod, and a rolling ball end of the rolling ball rod abuts against the vertical end face of the displacement disc.
