In this embodiment, the bearings 54 are fixed to the guards 51 at four corners of the partition frame 1 through the bearing seats 53, the outer rings of the bearings 54 are fixed to the bearing seats 53, the inner rings are fixed to the sprocket nuts 52, and the chain 43 is wound around the outer sides of the transmission teeth 521 of the sprocket nuts 52, so that the sprocket nuts 52 are driven to rotate when the chain 43 rotates, thereby achieving the lifting movement of the partition frame 3.

The turnover vehicle 100 is provided with the fixed partition board 1 and the plurality of lifting partition boards, so that the plurality of lifting partition boards are arranged on the upright post 2 at intervals, a plurality of temporary storage cavities 6 are formed, and more PCB boards can be conveniently stored.

In this embodiment, the bracket 41 of the driving assembly 4 may be fixed on the peripheral edge of the partition frame 3 as required, the peripheral edge of the partition frame 3 is grooved to facilitate leading out of the chain 43, the driving sprocket 421 is fixed on the bracket 41 through a bearing, the chain 43 wraps around the driving sprocket 421, the tensioning structures 44 are arranged on two sides of the driving sprocket 421, the tensioning wheels 442 of the tensioning structures 44 are fixed on the rotating grooves 4411 of the supporting frame 441 through a pin, the guide rods 4412 of the supporting frame 441 are sleeved with a spring 443, and the other side is pressed by the bracket 41 to realize constant-force tensioning of the chain 43. A power input shaft (i.e. the output shaft of the driving member 42) is coaxially fixed above the driving sprocket 421, and the power input side of the output shaft of the driving member 42 is square and can be driven by a manual or electric tool. When the clapboard frame 3 reaches the appointed position, the fixing of the position of the clapboard frame 3 can be realized by locking the clamping block.

When the transfer cart 100 of the present invention drives the chain 43 to rotate through the driving assembly 4, the chain 43 synchronously drives the sprocket nut 52 to rotate, and the screw nut pair composed of the sprocket nut 52 and the screw upright post 2 converts the rotation motion into a linear motion, so as to realize the synchronous rotation of the lifting clapboard frame 3. The turnover vehicle 100 realizes synchronous rotation of the chain wheel nuts 52 on the four corners of the lifting partition plate through power input, can quickly adjust the height of the temporary storage cavity 6 between two layers of the turnover vehicle 100, and achieves the purposes of improving labor efficiency and reducing labor cost.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
