During the conveying process, after the turnover conveying equipment is installed, the prefabricated panels enter the upper end face of the conveying face rack 21 from an assembly line at the upstream of the turnover conveying equipment, the front edges of the prefabricated panels are close to the conveying proximity switch, the conveying proximity switch conveys sensing signals to the control system 4, the control system 4 controls the motor 23 in the conveying driving mechanism to operate, the rotating shaft 22 rotates to drive the synchronous gears 24 of the rotating shaft 22 to rotate together, the synchronous belt 25 on the upper end face of the conveying face rack 21 drives the prefabricated panels to move along the assembly line direction (namely the length direction of the conveying face rack 21), when the front edges of the prefabricated panels are close to the stop proximity switch, all the prefabricated panels reach the proper positions on the upper end face of the conveying face rack 21 at the moment, the sensing of the proximity switch is stopped, corresponding signals are sent to the control system 4, and the control system 4 controls the, the prefabricated plate is stopped at the upper end face of the conveying face frame 21.

In the lifting process, after the prefabricated slab stops at the upper end face of the conveying face rack 21, four lifting power cylinders in the lifting driving mechanism are controlled to synchronously stretch out through the control system 4, the piston rod drives the lifting frame and the sliding block to upwards slide along the inclined plane on the inclined plane guide block to drive the lifting frame to upwards move until the roller is higher than the upper end face of the conveying face rack 21, and the roller lifts the prefabricated slab to be separated from the synchronous belt 25.

In the overturning process, after the precast slabs are lifted by the rollers, the piston rods of the overturning power cylinders 13 in the overturning device 1 are controlled to extend through the control system 4, the overturning face rack 12 is driven to rotate around the hinged shaft of the overturning face rack 12 and the foundation rack 11, the overturning face rack 12 is inclined, and the precast slabs slide downwards on the rollers in the overturning process until the precast slabs abut against the side edges of the limiting barrier strips; when the turnover face machine frame 12 inclines for a certain angle relative to the foundation frame 11, for example, when the turnover face machine frame is close to 90 degrees, the turnover proximity switch 6 senses and transmits a corresponding signal to the control system 4, the control system 4 controls the piston rod of the turnover power cylinder 13 in the turnover device 1 to stop moving, the turnover face machine frame 12 stops rotating, the turnover face machine frame 12 drives the precast slab to turn from the horizontal turnover state to the vertical state, and the turnover power cylinder 13 supports the turnover face machine frame 12.

Then, the plate product can be lifted off or processed, and after the completion, if the next process of plate product production needs to be carried out, the prefabricated plate can be laid flat from the vertical position by the turnover conveying equipment and then conveyed to a downstream production line.

By last, upset conveying equipment in this embodiment can link up on the assembly line of plate product, overturns and carries the plate product on line, upset conveying equipment easy operation, the upset and the transport of completion plate that can be automatic, degree of automation is high, manual operation has been reduced, can not influence the work of whole assembly line, work efficiency is high, safety and stability has reduced the emergence of production accident, can be less simultaneously to the wearing and tearing on plate product surface, has guaranteed product quality. In addition, the turnover conveying equipment is simple in structure.

In conclusion, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
