Vehicle body steel structure section size control device

Vehicle body steel structure section size control device relates to railway vehicle vehicle body steel structure and makes technical field, its universal wheel that includes frame, drag link mechanism, pressure plate mechanism, hydraulic pressure conduction mechanism and the brake of a plurality of area, the frame includes rectangle base, four vertical roof beams and two stiffening beams. The utility model discloses a controlling means can be effectual outside through the pressure extrusion from vehicle body steel structure, combines flame to transfer and repair technical control vehicle bodysteel structure cross dimensions to the reduction construction degree of difficulty reduces work load and shortens construction cycle, improves the quality of steel construction. 车体钢结构断面尺寸控制装置涉及轨道客车车体钢结构制造技术领域，其包括框架、拉杆机构、压板机构、液压传导机构和多个带刹车的万向轮；框架包括矩形底座、四个垂向梁和两个加强梁。本实用新型的控制装置可以有效的从车体钢结构外部通过压力挤压，结合火焰调修技术控制车体钢结构断面尺寸，从而降低施工难度，减少工作量以及缩短施工周期，提高钢结构的质量。
