[0058] When high-performance concrete is discharged into the interior of the casting assembly 5, the staff can pre-adjust the inclination angle of the rotating rod 503 according to the amount of high-performance concrete. When the interior of the distribution box 501 is loaded with high-performance concrete, the stirring shaft 512 provided on the rotating rod 503 can stir it during rotation. Specifically, when the amount of high-performance concrete is small, the rotating rod 503 rotates downward under electric drive, thereby reducing the height of the stirring shaft 512 rotatably installed on the rotating rod 503. External electricity drives the stirring shaft 512 to rotate through the motor. When the stirring shaft 512 is lowered to contact with the high-performance concrete, the multiple stirring blades 505 fixedly installed on the outer wall of the stirring shaft 512 can still stir the high-performance concrete inside the distribution box 501. A partition structure 510 is provided at the inner center of the distribution box 501. The partition structure 510 separates the distribution box 50 1 is divided into two left and right chambers. By continuously stirring the high-performance concrete inside the chamber, the high-performance concrete can be prevented from caking inside the distribution box 501. The two rotating rods 503 are fixedly installed with a first gear 506 at one end close to the fixed block 502. The first gear 506 is fixedly connected to the output end of the servo motor fixedly installed on the outside of the distribution box 501. When the first gear 506 rotates, the rotating rod 503 fixedly connected to the first gear 506 tilts. At the same time, the first rack plate 507 located between the two first gears 506 and meshing with the first gear 506 moves upward under the action of the meshing transmission. The lower end of the first rack plate 507 is rotatably connected to the transmission rod 508. When the first rack plate 507 moves upward, it can first pull the auxiliary plate 509 to slide along the bottom surface of the distribution box 501 through the transmission rod 508 (as shown in FIG. Figure 7 As shown), when the first rack plate 507 continues to move upward, under the traction of the transmission rod 508, the end of the auxiliary plate 509 can be driven to lift upward, thereby causing the auxiliary plate 509 to have an inclined slope (as shown). Figure 14 As shown), the high-performance concrete inside the two chambers of the auxiliary distribution box 501 is discharged. The cooperation of the rotating rod 503 and the auxiliary plate 509 can assist the high-performance concrete inside the distribution box 501 to be stirred and discharged, and a scraper 504 is slidably installed at the end of the rotating rod 503. When the rotating rod 503 rotates, the scraper 504 can scrape and clean the side walls of the distribution box 501 at both ends. When the rotating rod 503 rotates, the other two sides of the inner wall of the distribution box 501 can also be cleaned, thereby reducing the residual high-performance concrete attached to the inner wall of the distribution box 501. The setting of the auxiliary plate 509 also reduces the concrete residue at the bottom of the distribution box 501. The setting of the internal structure of the distribution box 501 can, on the one hand, prevent the high-performance concrete from caking and solidifying inside the distribution box 501, and on the other hand, improve the utilization rate of the high-performance concrete during use.

[0059] When the high-performance concrete loaded in the cloth box 501 needs to be discharged, it can be controlled by the multiple rectangular plates 803 arranged inside the discharging cylinder 801. The ends of the multiple rectangular plates 803 are fixedly installed with rotating shafts 802, and the rotating shafts 802 are fixedly connected with the second gear 804 arranged outside the discharging cylinder 801. The second gear 804 can rotate under the action of the second rack plate 805. In the process of extension and retraction of the output end of the electric telescopic rod 806, the second rack plate 805 can be driven to slide. When the second rack plate 805 slides, it can drive multiple second gears 804 to rotate synchronously under the action of meshing transmission, thereby controlling the synchronous rotation of multiple rectangular plates 803. In the process of feeding in the inside of the cloth box 501, multiple rectangular plates 803 can be rotated to a horizontal state. At this time, the discharge port 511 opened at the lower end of the cloth box 501 can be plugged (as shown in Figure 11 When it is necessary to pour the precast box girder, the multiple rectangular plates 803 are controlled to rotate to be vertically downward (as shown in Figure 12 At this time, the high-performance concrete in the inside of the cloth box 501 can be discharged through the inside of the discharging cylinder 801. When the worker needs to vibrate and compact the high-performance concrete in the mold 6, the multiple rectangular plates 803 can be rotated to an inclined state (as shown in Figure 13 At this time, the high-performance concrete in the inside of the cloth box 501 can be discharged to the next pouring position in the mold 6 under the guidance of the multiple rectangular plates 803. When the high-performance concrete poured in the mold 6 is vibrated, it is not necessary to stop the pouring assembly 5, which can further improve the continuity of the precast box girder during pouring;

[0060] The box girder specifically includes a bottom plate 1, two side webs, and a top plate. When pouring the precast box girder, the bottom plate 1 is located below the core mold. Two discharge ports 511 are opened on the bottom surface of the cloth box 501 to simultaneously pour both sides of the mold 6. The two discharge ports 511 are respectively arranged on both sides of the core mold in the mold 6. Discharging through the two discharge ports 511 can uniformly feed the area below the core mold in the mold 6, so that the bottom plate 1 of the precast box girder can be quickly filled with high-performance concrete during pouring, and the vibration effect of the compacting assembly 7 on the bottom plate 1 is better in the subsequent process. The voids caused by insufficient filling of concrete do not affect the vibration effect of the compacting assembly 7 on the bottom plate 1 of the precast box girder.

[0061] In the process of vibrating the high-performance concrete by the compacting assembly 7, the mechanical arm 702 accommodated outside the mold 6 is unfolded, and the vibrating rod 705 arranged at the end of the mechanical arm 702 can be inserted into the high-performance concrete in the mold 6 obliquely downward under the control of the mechanical arm 702, and the adjusting frame 706 movably connected on the expansion block 704 can further finely control the position and the oblique angle of the vibrating rod 705, in the process of unfolding the mechanical arm 702, the mechanical arm 702 can move to the lower end of the control assembly 8 horizontally preferentially, and the convex block 703 is fixedly installed at the end of the mechanical arm 702, when the convex block 703 contacts the contact sensor 807 fixedly installed at the lower end of the discharging cylinder 801, the contact sensor 807 can transmit the signal to the controller (model), under the action of the controller, the rectangular plate 803 can be adjusted to the inclined state through the telescopic electric rod 806, and then the high-performance concrete in the cloth box 501 is discharged to the next pouring site, under the cooperation of the pouring assembly 5 and the compacting assembly 7, the pouring work of the precast box girder can be completed in layers and continuously.

Accordingly, such modifications and changes are intended to fall within the scope of the present application.
