Adjusting and repairing device for corner post plates of end wall of open wagon

Abstract

The invention discloses an adjusting and repairing device for corner post plates of an end wall of an open wagon. The adjusting and repairing device comprises a main beam and two pairs of supports symmetrically welded to the two sides of the main beam, wherein universal wheels are fixedly installed at the bottoms of the supports respectively; a hydraulic oil cylinder is fixedly connected to one end of the main beam; a left adjusting and repairing ejector head is fixedly connected to a telescopic ejector rod of the hydraulic oil cylinder; and a right adjusting and repairing ejector head is welded to the other end of the main beam. According to the adjusting and repairing device, the corner post plates are adjusted and repaired in a segmented adjusting and repairing mode, and the adjusting and repairing radian of the corner post plates is controlled by controlling the output pressure of a pump station. The contact area between the hydraulic oil cylinder and the corner post plates is increased through the adjusting and repairing ejector heads, and the pressure of the adjusting and repairing ejector heads is consistent with that of the corner post plates on the two sides through the two rectangular adjusting and repairing ejector heads with the same area. The sliding resistance of the main beam and the end wall plates is reduced through the universal wheels below the main beam, andthe labor intensity in the adjusting and repairing process of the end wall is relieved.

Description

technical field [0001] The invention relates to a device for adjusting and repairing a corner column plate at the end wall of a gondola car, and belongs to the technical field of pairing installation of gondola cars. Background technique [0002] see image 3 , During the prefabrication process of the end wall of the C70E gondola car, there are two full-length welds 9 between the corner post plate 7 and the corner post 8. After the weld seams 9 are welded, the corner post plate 7 undergoes welding deformation, and the corner post plate 7 is sunken toward the inner side of the end wall. The concave radian is 5-8mm. The concavity of the corner post plate 7 will affect the concavity of the corner post reinforcement plate, which will indirectly cause the gap between the lower door panel and the corner post reinforcement plate to exceed the limit, increase the workload of the lower door panel adjustment and repair in the later stage, affect the overall appearance quality of the l...
