Abstract

The invention discloses a correcting machine for a van body of a large and medium van. The correcting machine comprises a platform, four axle positioning devices fixed to the platform, two to six columns capable of moving relatively along the platform and then being locked, and a hydraulic system, wherein each column comprises a vertical column body and a first chain guide wheel fixedly connected with the vertical column body. Different from the prior art, a heightening vertical column is fixedly connected with the upper end of each vertical column body and provided with pin holes at different heights, a third chain guide wheel, a hoisting arm and a supporting arm are inserted in the pin holes of each heightening vertical column from top to bottom, and each second tensioning chain is sequentially wound on the corresponding first chain guide wheel, the corresponding third chain guide wheel and a fourth chain guide wheel. Compared with the prior art, the correcting machine can not only carry out tensioning through the tensioning chains, but also carry out ejection and pressing on a deformed part, can carry out vertical and upward tensioning repair to correct deformation, has higher acting force on the deformed part and is good in repairing effect.

Description

technical field [0001] The invention relates to vehicle maintenance equipment, in particular to a correction device for the body of a large and medium-sized passenger and freight vehicle. Background technique [0002] Publication No. CN 102266879 B discloses a body correction device for a large passenger and freight vehicle, wherein the bottom end of the stretching oil cylinder is seated on the transverse arm of the tower and is located at the rear side of the longitudinal arm of the tower. A first chain guide wheel with a fixed position and a second chain guide wheel with a position that can move up and down are installed on the longitudinal arm of the tower column; A top pressure oil cylinder seat is installed on the front side wall of the tower column longitudinal arm, and a top pressure oil cylinder whose telescopic direction is perpendicular to the direction of the tower column longitudinal arm is installed in the top pressure oil cylinder seat. The tower can be stretc...
