[0002] Precast box girders are concrete box beams prefabricated in factories or prefabrication sites. They are primarily used in large-scale construction projects such as bridges, offering advantages such as efficient construction, controlled quality, and accelerated project schedules. During the production process of the bottom web of a precast box girder, stirrups are laid onto a cradle, horizontal reinforcement is threaded through the top and bottom of the stirrups, and finally, the stirrups and horizontal reinforcement are welded together to form the bottom web skeleton.

[0003] In the existing technology, the horizontal reinforcement is usually threaded manually or with a simple pulley device. The horizontal reinforcement is placed on the pulley device and pushed to thread the horizontal reinforcement. This method is time-consuming, labor-intensive, and has low work efficiency and low intelligence and automation levels, which leads to a prolonged production cycle of prefabricated box girders.

The slide of the sleeve slide cylinder 414 moves backward, causing the receiving plate 416 to move below the side plate 412, allowing the plastic tube to fall into the receiving groove of the receiving plate 416, and then the slide of the sleeve slide cylinder 414 moves forward to move the plastic tube out of the side plate 412. During the movement, the baffle 417 blocks the plastic tube in the side plate 412 to prevent the remaining plastic tubes from falling.

[0067] The working mode of the present invention is:

[0068] When threading one of the horizontal bars that needs to be welded below the stirrups, the travel motor 115 of the travel mechanism 11 is started, driving the gear 116 to rotate on the rack 112, so that the frame 113 can move back and forth, thereby driving the straightening machine 12 to move to the position of the front lower support mechanism 21. The steel bars enter the straightening machine 12, are straightened and then sent out, and first enter the No. 1 lower support plate 212, and then enter the No. 2 lower support plate 214, so that the horizontal bars are lowered to the welding height of the stirrups; when the horizontal bars enter between the active conveying component 312 and the driven conveying component 313 of the first lower conveying mechanism 31, the piston rod of the clamping cylinder 3142 of the clamping component 314 is extended, driving the movable plate 3132 to move toward the active pressure wheel 3126, so that the driven pressure wheel 3135 presses the steel bars on the active pressure wheel 3126, and at the same time, the positioning component 316 and the guide component 317 simultaneously position and guide the horizontal bars to ensure the stability of the horizontal bar conveying, and then the conveying motor 3123 drives the active shaft 3125 and the active pressure wheel 3126 to rotate, so that the active pressure wheel 3126 and the driven pressure wheel 3135 convey the steel bars to the right. When the end of the horizontal bar can no longer be transported, the piston rod of the lifting cylinder 3151 extends, driving the lifting plate 3152 and the material-discharging cylinder 3153 to rise, so that the end of the horizontal bar enters the material-discharging piece 3155. Then the piston rod of the material-discharging cylinder 3153 extends, driving the material-discharging piece 3155 to move to the right, so that the left wall inside the material-discharging piece 3155 pushes the end of the steel bar to move to the right, sending the end of the horizontal bar out, and completing the threading of the horizontal bar.

[0069] When threading another horizontal reinforcement welded below the stirrup, the straightening machine 12 is moved to the position of the rear lower support mechanism 21 in the above manner, and the reinforcement is transported through the second lower conveying mechanism 32 to complete the threading.

[0070] When the horizontal reinforcement that needs to be welded above the stirrups is threaded, the straightening machine 12 moves to the position of the front upper support mechanism 22 through the walking mechanism 11. The steel bar enters the straightening machine 12 for straightening and is then sent out and enters the upper support plate 222. The height of the upper support mechanism 22 remains unchanged, so that the horizontal reinforcement meets the threading height requirement. When the horizontal reinforcement enters the first upper conveying mechanism 33, the first upper conveying mechanism 33 continues to convey the horizontal reinforcement to the right. At the same time, the sleeve slide cylinder 414 of the first sleeve mechanism 41 moves forward, and the plastic tube that falls into the receiving plate 416 is moved forward to the horizontal reinforcement position. The horizontal reinforcement is aligned with the plastic tube through the guide assembly 317. When the first upper conveying mechanism 33 conveys the horizontal reinforcement, the right end of the horizontal reinforcement is inserted into the plastic tube to achieve the sleeve of the horizontal reinforcement. After the sleeve of the horizontal reinforcement is completed, the first upper conveying mechanism 33 continues to convey and sends the end of the horizontal reinforcement out through the material diverting assembly 315, completing the threading of the horizontal reinforcement.

[0071] When threading another horizontal reinforcement welded above the stirrup, the straightening machine 12 is moved to the position of the rear upper support mechanism 22 in the above manner, transported by the second upper conveying mechanism 34, and sleeved by the second sleeve mechanism to complete the threading.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
