The base 10 is an installation base of the whole device, and can be a formed steel structure base, a site base formed at a station, such as a reinforced concrete base, or a combined structure of the site base and a steel structure frame.

The turning bracket 30 has a certain supporting height, is fixed on the base 10, and is used for rotatably supporting the turning jig 40, so that the turning jig 40 can smoothly and stably rotate in a certain height space.

The overturning jig 40 is used for installing and fixing a wagon body 70 of a railway wagon to be welded, so that the wagon body 70 can rotate along with the overturning jig 40, and the whole space posture of the wagon body 70 can be adjusted, so that welding operation can be conveniently carried out by welding operators. The overturning jig 40 is internally provided with a fixing mechanism for contacting and fixing the vehicle body 70, such as a vehicle body clamp 90 matched with the vehicle body 70, or a similar clamping tool, so as to stably fix the vehicle body 70 and keep the state stable.

The operation platform 60 is used for welding operators to stand and move, and is arranged on the overturning jig frame 40; so that after the turning jig 40 and the vehicle body 70 fixed thereto are turned in place, an operator can stand and move on the operation platform 60 to perform a welding operation within a certain range; without standing on the vehicle body 70, the safety, convenience and efficiency of the welding operation are improved to some extent. In view of the large welding area in the longitudinal and width directions of the vehicle body 70, the operation platform 60 may be generally disposed on the sides of the top and bottom surfaces of the vehicle body 70, so that the requirement of the welding position of the entire vehicle body can be basically satisfied.

In some embodiments, in some pipelined welding lines, each station only performs welding in one plane, in each station, only one spatial placement posture of the vehicle body 70 is provided, the operation platform may be correspondingly disposed on one side of the vehicle body 70, after the vehicle body 70 moves to the current station, the operation platform 60 is in a posture that can stand stably after the vehicle body 70 is turned by the turning jig 40 to achieve spatial posture adjustment of the vehicle body 70, so as to facilitate welding operation and movement.
