Polishing device for steel box girder T rib sliced mouth

Abstract

The invention relates to engineering equipment, in particular to a polishing device for a steel box girder T rib sliced mouth. The polishing device comprises a jig frame, a fixture, a travelling trolley, a grinder installation frame and a grinder; the jig frame comprises a stand column, a transverse beam and track beams; the track beams are connected with the upper end of the stand column; the transverse beam is transversally connected between the track beams and is provided with the fixture; the upper surfaces of the track beams are provided with slide rails; wheels of the travelling trolleyare matched with the slide rails and travel along the slide rail paths; and the travelling trolley is provided with the grinder installation frame which is provided with the grinder. The invention can be connected with multiple transverse beams to enable a bulk of T ribs to be arranged on the fixture, a regulating rod is pushed to drive a motor grinder to move straightly along a media axis of thetrack beams, and meanwhile, a sliced mouth angle of the T rib is polished; therefore, a bulk of T rib sliced mouths can be polished during the traveling of the travelling trolley with high productionefficiency. The invention has the advantages of simple structure, low construction cost, good rigidity, high planeness, simplified manual operation procedure, convenience and safety.

Description

technical field [0001] The invention relates to engineering equipment, in particular to a grinding device for T-rib cuts of steel box girders. Background technique [0002] Steel box girder, also known as steel plate box girder, is a commonly used structural form of long-span bridges, and its application is becoming more and more extensive. In order to strengthen the strength of the beam, there are many T-ribs on the steel box girder. Before assembly, the T-rib section needs to be polished to make the welding connection firm. If only manual grinding is required, the labor intensity will be greater and the production efficiency will be lower. lower. Therefore, it is necessary to improve the grinding method of the T-rib slit of the existing steel box girder, in order to be able to grind in batches, improve production efficiency and reduce labor intensity at the same time. Contents of the invention [0003] In view of the above problems, the object of the present invention ...
