Description

TECHNICAL FIELD

[0001] The utility model relates to the stainless steel rail vehicle manufacturing technical field especially relates to a rail vehicle adjustable car mounting device. BACKGROUND

[0002] In the stainless steel rail vehicle manufacturing process, after the stainless steel car body assembly welding is completed, it needs to be hoisted to the car mounting stool to carry out the detection of various sizes inside, and according to the detection result, cold adjustment and repair and flame adjustment and repair are carried out, and after the detection and assembly welding process, the welding of various small parts inside and outside is carried out.

[0003] The car body steel structure car mounting position is generally in the bolster beam area, supported on the lower surface of the side beam on both sides of the air spring support surface.
