Fig. 2 is a structural schematic diagram of the connecting rod releasing mechanism shown in Fig. 1 .

Detailed ways

As shown in Figures 1 and 2: 1 is a vehicle frame, and casters 2 are installed at the four corners below the vehicle frame 1 for walking.

Four corners above the vehicle frame 1 are equipped with a vertical connecting rod release mechanism 3, the connecting rod release mechanism 3 includes a bracket 10, the bottom end of the bracket 10 is welded with a connecting plate 18, and the connecting rod 18 and the bolt are connected The bracket 10 is fixedly connected to the vehicle frame 10 .

As shown in Figure 2: the first support plate 16 is connected to the lower part of the bracket 10 through the first support plate shaft 15; Axle 17, on the bracket 10, is positioned at the upper rear side of the first support plate shaft 15 and is provided with the first lower limit shaft 12, and the lower end of the first connecting rod 11 has a first connecting rod elongated hole 14, and the first connecting rod 11 Connect with the first support plate 16 through the first connecting rod pin 13 and the first connecting rod long hole 14;

On the support 10, the top of the first support plate 16 is connected with the second support plate 20 through the second support plate shaft 19. The upper limit shaft 24 is provided with the second lower limit shaft 23 on the upper rear side of the second support plate shaft 19 on the support 10, and the second connecting rod elongated hole 22 is arranged at the lower end of the second connecting rod 25, and the second connecting rod 25 is connected with the upper end of the second support plate 20 and the first connecting rod 11 through the second connecting rod pin shaft 21 and the second connecting rod long hole 22;

On the bracket 10, they are arranged sequentially according to the above-mentioned support plate structure from bottom to top, and there are at least two groups.

After the above-mentioned support plates are installed, the first support plate 16 located at the bottom is in an inclined state, that is, the front end is positioned at the outside of the support 10, and each support plate above is at the inside of the support 10, and the angle of each support plate It is determined by the positions of the support plate shafts, limit shafts and connecting rod pin shafts.

As shown in Figure 1, both sides of the connecting rod release mechanism 3 are provided with vertically arranged guide rods 4 connected with the vehicle frame 1.

When adorning the body-in-white workpiece, the workpiece is placed from top to bottom earlier, because each support plate on the top is positioned at the inner side of the support 10, the workpiece is not blocked. Since the bottom first support plate 16 is inclined to the outside of the support 10, the first workpiece is dropped thereon, and the first support plate 16 rotates along the first support plate axis 15 under the gravity of the workpiece. When the horizontal position is reached, the position is blocked by the first lower limit shaft 12, and the first support plates 16 at the four corners jointly support the first body-in-white workpiece. During the rotation of the first support plate 16, the first connecting rod pin 13 rotates upwards accordingly, and drives the first connecting rod 11 to move upward. When the first connecting rod 11 moves upward, the second connecting rod pin 21 The second connecting rod long hole 22 moves up, and at the same time, the second support plate 20 starts to rotate under the drive of the second connecting rod shaft 21, so that its front part is located on the outside of the bracket 10, and the second connecting rod pin 21 is in this process. Do not promote the second connecting rod 25 actions temporarily in the middle. At this time, the second workpiece can be placed, which is supported by the second support plate 20 during placement, and the second support plate 20 is rotated to a horizontal state by the gravity of the workpiece during placement. By analogy, according to the number of support plates, multiple body-in-white workpieces can be placed to ensure that the workpieces do not touch or collide, and one vehicle can transport multiple workpieces. When the workpiece is placed, it can be guided by the guide rod 4 to prevent deflection when falling.
