[0011] The usage method of the box girder steel bar processing system includes the following steps:

[0012] Step S1, the steel bar conveying system sends box girder steel bars of different specifications to the corresponding steel bar bending system, and the steel bar conveying system transfers the corresponding box girder steel bars into the bending component in the steel bar bending system;

[0013] Step S2, the bending component bends the received box girder steel bars. The processed box girder steel bars are transferred into the steel bar rack, and the box girder steel bars are arranged and temporarily stored in the steel bar rack in sequence;

[0014] Step S3, the transfer power unit grabs the steel bars processed by the bending component and temporarily stored on the steel bar rack. The grabbed steel bars are then transferred by the transfer power unit to the arrangement partitions. The box girder steel bars transferred to the arrangement partitions are supported by the arrangement partitions and maintain a fixed spacing;

[0015] In step S4, with the cooperation of the moving track and the moving part, the hook runs above the arranging partition where the steel bars are arranged. The pre-arranged steel bar transfer system is lowered into the outer frame along with the hook. The steel bar locking part in the pre-arranged steel bar transfer system is supported by the support frame and connected to the arranged steel bars. In the connected state, the steel bar locking part locks the steel bars.

[0016] In step S5, the hook lifts the support frame and the steel bar locking part. Under the restriction of the steel bar locking part, the arranged box girder steel bars are synchronously lifted out from above the outer frame in the pre-arranged order.

[0017] In step S6, after the hook drives the pre-arranged steel bar transfer system to move to a specified position above the box girder mold with the cooperation of the moving track and the moving part, the hook lowers the pre-arranged steel bar transfer system into the mold. Under the restriction of the pre-arranged steel bar transfer system, the relative positions of the box girder steel bars are fixed.

[0018] In step S7, the box girder steel bars are welded and fixed to the other steel bars in the mold. After the box girder steel bars are connected to the other steel bars in the mold, the steel bar locking part in the pre-arranged steel bar transfer system releases the locking of the steel bars. At this time, the hook drives the pre-arranged steel bar transfer system to move out of the mold with the cooperation of the moving track and the moving part.

[0019] In step S8, the removed pre-arranged steel bar transfer system is transferred into the box girder mold. The mold is partitioned according to the types of steel bars, and the transfer and positioning are carried out according to the layout partition of the existing steel bars in the box girder mold. The pre-arranged steel bar transfer system is transferred from the hoisting system to the positioned partition. The hoisting system lowers the pre-arranged steel bar transfer system to the partition position, and the pre-arranged steel bar transfer system releases the clamped steel bars.
