In practice, the position limiting assembly may be disposed on top of the supporting frame 102, or on top of the supporting beam 101. For example, in the preferred embodiment, the support members are disposed on the top of two support frames 102 at both ends of the vehicle body 1, and the support members are two spacing posts 103 disposed on the top of the support frames 102 at intervals, as shown in fig. 1.

In the practical application process of this embodiment, the distance between two adjacent limiting columns 103 is 0.2m to 1.0 m.

In addition, when actually setting up, when the width of automobile body 1 is great, can set up a plurality of spacing posts 103 in the horizontal interval at automobile body 1 both ends for can realize placing side by side and spacing fixed of a plurality of thin roof beam bodies 3 simultaneously on the automobile body 1, and ensure that can not appear mutual extrusion, collision between each thin roof beam body 3 in the turnover in-process, fully guarantee the reliability of roof beam body turnover in-process.

In order to realize the adjustment of the spacing between the limiting columns 103, various forms can be adopted; the preferred embodiment is exemplified by the form of a spacing assembly comprising two spacing posts 103, as described in more detail below with respect to several embodiments.

In one embodiment, one of the posts 103 in the stop assembly is fixed, and a rotating screw is transversely disposed with respect to the other post 103, so that a spiral displacement mechanism is formed between the posts 103 and the rotating screw, and then the rotating screw is rotated to control the posts 103 to approach or separate from the fixed posts 103.

In another embodiment, two limiting columns 103 in the limiting assembly are matched at two ends of the same rotating screw rod at the same time, and two ends of the rotating screw rod are respectively provided with threads with opposite rotation directions, i.e. the rotating screw rod is a bidirectional rotating screw rod; at this time, the rotating screw rod is rotated forward or reversely, so that the opposite control or the back-away movement between the two limiting columns 103 can be realized, and the distance between the two limiting columns is changed.

In another embodiment, the limiting assembly includes at least one movable limiting column, and a plurality of mounting holes are formed in the support frame 102 at intervals for the movable limiting column, and the bottom of the movable limiting column can be correspondingly embedded in the corresponding mounting hole, and by changing the embedding position of the movable limiting column, the distance between the limiting columns 103 in the limiting assembly can be correspondingly changed, so as to adapt to the bearing requirements of different thin beam bodies 3.

In more detail, the universal wheel 201 is mounted to the bottom of the support frame 102 by a mount 202.

Obviously, in order to ensure the running reliability of the vehicle body 1, at least one running mechanism 2 can be correspondingly arranged in the middle of the vehicle body 1, so as to realize the reliable support of the middle of the vehicle body 1.

In addition, during actual installation, the number of the supporting frames 102 may be a plurality of supporting frames 102 arranged at a lateral interval, and in this case, two adjacent supporting frames 102 are connected by a plurality of supporting beams 101, and finally, an integral structure is formed. Certainly, in actual setting, when the length of the supporting beam 101 is large, a corresponding reinforcing rod can be welded in the middle of the supporting beam 101, and then a structure similar to the supporting frame 102 is formed in the middle of the vehicle body, at this time, the supporting beam 101 is of an integral structure, and the stress reliability of the supporting beam can be better guaranteed.

In a specific application scenario of the turnover device, it is used to achieve turnover of the thin beam 3 as shown in fig. 3, in this case, the thin beam 3 is formed by sequentially butt-welding three U-shaped beam units 301, and two U-shaped welds 302 are formed in the middle, during the preparation of the thin beam 3, it is necessary to perform multiple flaw detection of the welds 302, and repair-weld the defect positions according to the detection results. Meanwhile, the welded part is always required to be reshaped after being cooled, so that the flatness of the bottom surface is less than or equal to 1.5, the flatness of two side surfaces is less than or equal to 1.5, the straightness of the upper surface is less than or equal to 1, and the surface is not allowed to be scratched.

Due to the above processes, the thin beam body 3 needs to be transferred for many times. In actual transfer, the arrangement form of the thin beam body 3 on the vehicle body 1 is shown in fig. 3, and at this time, the two transverse sides of the thin beam body 3 are limited by two pairs of limiting columns 103, so that the limiting reliability in the turnover process of the beam body is ensured. In addition, when actually placing, the two welded joints of the thin beam body 3 are preferably placed right above the vehicle body 1, so as to avoid additional influence on the welded parts during the transfer process. In addition, in actual installation, the length of the vehicle body 1 is preferably 1.5m to 3m, and may be more preferably 2m, which may be preferable according to the actual product length of the thin beam body 3.

More specifically, in order to avoid collision and friction between the vehicle body 1 and the thin beam body 3, a rubber pad is provided on the inner wall surface of the stopper column 103 and/or the top surface of the vehicle body 1.
