[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0024] like Figures 1-4As shown in the figure, an embodiment of this utility model proposes a steel bar trailer for bridge construction, including a mobile chassis 1, a frame 2 fixedly connected to the upper surface of the mobile chassis 1, the frame 2 being used to place steel bars, a fixed seat 3 fixedly connected to the lower surface of the frame 2, the fixed seat 3 penetrating the mobile chassis 1, a square hole provided on one side of the fixed seat 3, a sliding rod 4 slidably connected in the square hole, a first support plate 5 fixedly connected to one end of the sliding rod 4, and multiple movable support components 6 provided on the sliding rod 4, each movable support component 6 including a sliding seat 61 and the sliding rod 4. A square through groove is provided on one side of the fixed seat 3, and the sliding seat 61 is located in the square through groove. The sliding seat 61 is slidably connected to the sliding rod 4. Support plates 62 are fixedly connected to both sides of the sliding seat 61. A second support plate 63 is fixedly connected to the upper surface of the two support plates 62. A circular through hole is provided on both the sliding seat 61 and the support plate 62. A bolt 7 is placed in the circular through hole and passes through the support plate 62 and the sliding seat 61. A fastening nut 8 is installed on the outside of the bolt 7. A threaded hole is provided on the lower surface of the fixed seat 3. The threaded hole communicates with the square hole and is tightly connected by threads in the threaded hole. When using the fastening screw 9, if the steel bar to be transported is too long, pull the sliding rod 4 to pull it out from the fixed seat 3, rotate the fastening screw 9 on the fixed seat 3 to squeeze the sliding rod 4 and fix it. Then, push the multiple movable support components 6 between the first support plate 5 and the frame 2 to distribute the movable support components 6 evenly. When the steel bar is placed on the frame 2, it is supported by the multiple movable support components 6 on the frame 2 and the sliding rod 4, increasing the length that can be supported. This allows for support of longer steel bars and prevents the steel bars from swaying up and down during movement, which could cause them to bend. When the steel bar is not being transported, the sliding rod 4 is located in the fixed seat 3. The overall length of the trailer is not large, making it convenient to place and carry. At the same time, when transporting steel bars, the length of the sliding rod 4 that can be pulled out can be controlled according to the length of the steel bar, so that the device can adapt to steel bars of different lengths and increase the range of use of the device. The movable support components 6 are driven to slide by the sliding seat 61 and supported by the second support plate 63. After moving, rotate the fastening nut 8 to fix the sliding seat 61.

[0025] like Figure 4 As shown, two baffles 10 are fixedly connected to the upper surface of the frame 2. Vertical plates 11 are fixedly connected to the upper surfaces of the two baffles 10. A servo motor 12 is fixedly connected to one side of the vertical plate 11. The main shaft of the servo motor 12 is fixedly connected to a winding wheel 13. A traction rope 14 is wound on the winding wheel 13. Two fixing blocks 15 are fixedly connected to the upper surface of the first support plate 5. The other end of the traction rope 14 is fixedly connected to the fixing block 15. The baffles 10 are located on both sides of the frame 2 to prevent the steel bars from rolling off the sides of the frame 2. When the sliding rod 4 is pulled out, the servo motor 12 drives the winding wheel 13 to rotate and release the traction rope 14. When the sliding rod 4 is fixed by the fastening screw 9, the servo motor 12 stops. At this time, the traction rope 14 pulls the first support plate 5 at one end of the sliding rod 4 to prevent the steel bars from pressing on the sliding rod 4. The large gravity will cause the sliding rod 4 to bend.

[0026] like Figure 4 As shown, multiple fixing plates 16 are fixedly connected to the upper surfaces of both baffles 10. Each fixing plate 16 has a through groove, and a sliding block 17 is slidably connected within the groove. The fixing plates 16 on the two baffles 10 face each other, and an elastic rope 18 is connected between the two opposing sliding blocks 17. Two horizontal plates 19 are fixedly connected to one side of all the fixing plates 16. A threaded rod 20 is rotatably connected between the two horizontal plates 19. The threaded rod 20 passes through the sliding block 17 and is threadedly connected to the sliding block 17. One end of the threaded rod 20 passes downward through the horizontal plate 19. When the device transports a small amount of steel bars, the threaded rod 20 is rotated to... As the sliding block 17 descends, the elastic rope 18 approaches the surface of the frame 2, pressing the reinforcing bars onto the elastic rope 18. The elastic rope 18 bends, promoting the gathering of the reinforcing bars towards the center of the frame 2. When transporting a large number of reinforcing bars, the bars accumulate on the frame 2 at a high height. Before placement, the sliding block 17 can be moved to a higher position. After the reinforcing bars are placed, the sliding block 17 is lowered, and the elastic rope 18 presses down on the topmost reinforcing bar from top to bottom, squeezing the reinforcing bars to prevent the pile of reinforcing bars from shaking and collapsing during transport. At the same time, when transporting the reinforcing cage, the elastic rope 18 prevents the reinforcing cage from rolling back and forth.

[0027] Working principle: Pull the sliding rod 4 to pull it out from the fixed seat 3. Rotate the fastening screw 9 on the fixed seat 3 to squeeze the sliding rod 4 and fix it. The servo motor 12 drives the winding wheel 13 to rotate, releasing the traction rope 14. The sliding seat 61 slides, driving the second support plate 63 to move and adjust its position to support the steel bars. When the device transports a small amount of steel bars, rotate the threaded rod 20 to lower the sliding block 17. The elastic rope 18 approaches the surface of the frame 2, pressing the steel bars onto the elastic rope 18. The elastic rope 18 bends, promoting the steel bars to gather towards the middle of the frame 2. When transporting a large amount of steel bars, the steel bars accumulate on the frame 2 to a high height. Before placing them, the sliding block 17 can be moved to a higher position. After the steel bars are placed, control the sliding block 17 to descend, and the elastic rope 18 presses down on the topmost steel bar from top to bottom, squeezing the steel bar.
