The invention belongs to the technical field of machinery and relates to a positioning device for I-shaped steel parts of steel structure bridges. The present invention comprises two mounting frames, a roller mechanism is arranged between the bottoms of the two mounting frames, and an L-shaped placing plate is arranged on the mounting frame, and the L-shaped placing plate includes a bottom plate and a side plate, and there is a gap between the side plate and the mounting frame. There is a first driving mechanism that can drive the L-shaped placing plate to move up and down, a plurality of support wheels are arranged on the bottom plate, a plurality of first clamping wheels are arranged on the bottom plate, and an energy can be set between the first clamping wheel and the side plate. The second drive mechanism that drives the first clamping wheel to move left and right has a fixed plate on the bottom plate; and a top wheel mechanism that can position the connecting plate and the lower wing plate on the roller mechanism on the two mounting frames. The invention has the advantages that the connecting plate and the two wing plates are quickly pre-assembled into an I-shaped steel piece to facilitate welding and improve the production efficiency of the I-shaped steel piece.
Description
technical field [0001] The invention belongs to the technical field of machinery, and relates to a positioning device for an I-shaped steel piece of a steel structure bridge. Background technique [0002] Steel structure bridges are used more and more in modern bridge construction. Steel structure bridges often include many I-shaped steel parts. These I-shaped steel parts include two upper and lower wing plates and a connecting plate between the two wing plates. The width of the wing plate is about 0.5 meters and the length is more than ten meters; the width of the connecting plate is between 3 and 5 meters, and the length and the wing plate match. At present, in the production process of these I-shaped steel parts, a wing plate is placed horizontally by a crane, and the connecting plate is placed vertically on the wing plate, and then the welding machine welds the wing plate and the connecting plate together to form a T-shape artifact. Then, the crane places the other w...
