[0002] Bridge deck system components are important prefabricated components in railway construction. Due to the large weight and irregular structure of bridge deck system components, they need to be flipped after the demolding process to facilitate transportation and storage. However, in the existing production process of bridge decks, after the demolded bridge deck system components are transported to the flipping station of the bridge deck system components, they are usually flipped twice by 90° through the bridge deck flipping device, and then the flipped bridge deck system components are transported to the transfer line by a hoisting device. The existing demolding and flipping method of bridge deck system components has the disadvantages of cumbersome process, and is extremely easy to damage the demolded bridge deck system components, seriously affecting the qualified rate and production efficiency of bridge deck system component products. Therefore, it is necessary to develop a demolding and flipping device, a production line and a demolding and flipping method for bridge deck system components with simple process and high demolding and flipping efficiency.
