[0035] Traction bridges 10 are arranged on both sides of the finished product transportation line 20; the traction bridge 10 includes traction longitudinal beams 11; guide rail assemblies 12 are arranged on the traction longitudinal beams 11; bridge support columns are connected to the bottom of the traction longitudinal beams 11 for supporting the traction longitudinal beams 11.

[0036] Both ends of the finished product traction mechanism 30 are arranged on the traction longitudinal beams 11 on both sides of the finished product transportation line 20, and under the coordinated action of the finished product conveyor line, the finished product 40 of the steel bar skeleton is dragged along the traction longitudinal beams 11 as a whole to move forward to the front end of the traction longitudinal beams 11. As Figure 1 shown, the end of the traction longitudinal beam 11 where the finished product traction mechanism 30 is arranged is the front end of the traction longitudinal beam 11, and the end where the finished product traction mechanism 30 is not arranged is the rear end of the traction longitudinal beam 11. For the convenience of understanding, the end of the longitudinal bar used for connecting with the finished product traction mechanism 30 is also the front end of the longitudinal bar.

[0037] The finished product traction mechanism 30 includes a traction drive assembly 31, a traction crossbeam 32, and a longitudinal bar clamping tooling 33.

[0038] When producing the steel bar framework of precast box girders for highways, a stirrup magazine and a welding station are also provided at the rear end of the traction longitudinal beam 11. A plurality of stirrup frameworks arranged in sequence are hung on the stirrup magazine. The front ends of the longitudinal bars of the steel bar framework of the precast box girder for highways sequentially pass through the stirrup frameworks on the stirrup magazine and are connected to the longitudinal bar clamping tooling 33, so that the finished product traction mechanism 30 can traction the longitudinal bars and the finished steel bar framework 40 as a whole to move forward to the front end of the traction longitudinal beam 11.

The connecting frame plate 334 has a cross-sectional profile similar to that of the stirrup framework. The locking parts can be locking bolts or locking nuts. After the front ends of the longitudinal bars sequentially pass through the jacks 332 on the longitudinal bar fixing plate 331 and the connecting frame plate 334, they are connected to the locking parts, so as to fix the longitudinal bars to the longitudinal bar clamping tooling 33.

[0042] The connecting frame plate 334 is detachably connected to the longitudinal bar fixing plate 331; the cross beam transition plate 333 is detachably connected to the connecting frame plate 334. By disassembling the connecting frame plate 334, the cross beam transition plate 333 and the longitudinal bar fixing plate 331, different types of longitudinal bar fixing plates 331 can be replaced, so that the positions and numbers of the jacks 332 on the longitudinal bar fixing plate 331 are different to be applicable to the production of box girder steel bar frameworks of different sizes.

[0043] As Figures 4-8As shown, the traction drive assembly 31 includes a motor mounting base 311, a traction drive motor 312, a traction gear 313, and a traction rack 314; the motor mounting base 311 is connected to the traction crossbeam 32; the traction drive motor 312 is mounted on the motor mounting base 311, and the output shaft of the traction drive motor 312 is connected to the traction gear 313; the traction gear 313 meshes with the traction rack 314 fixed to one side of the traction longitudinal beam 11.

[0044] The guide rail assembly 12 includes an anti-overturning guide rail 121, anti-overturning rollers 122, a support guide rail 123, a roller box 124, and a roller assembly; the anti-overturning guide rail 121 is fixed to one side of the traction longitudinal beam 11; the anti-overturning rollers 122 cooperate with the anti-overturning guide rail 121 and are connected to the motor mounting base 311. The support guide rail 123 is arranged on the top of the traction longitudinal beam 11; the roller box 124 is connected to the traction crossbeam 32, and the roller box 124 is internally provided with a roller assembly, and the roller assembly cooperates with the support guide rail 123.

[0045] As Figure 7 shown, the anti-overturning guide rail 121 is arranged below the traction rack 314 and is arranged parallel to it. The anti-overturning rollers 122 are located below the anti-overturning guide rail 121.

[0046] The roller assembly includes a vertical roller 125 that rolls in a vertical plane and a horizontal roller 126 that rolls in a horizontal plane; the vertical roller 125 cooperates with the top of the support guide rail 123; the horizontal roller 126 cooperates with both sides of the support guide rail 123.

[0049] A drag chain groove 13 is also arranged on one side of the traction longitudinal beam 11.

[0050] The working process of the finished product feeding device for the production of highway precast box girder steel skeletons in this embodiment includes the following steps:

[0051] S1. Before welding the longitudinal bars and stirrup skeletons, move the finished product traction mechanism 30 to the rear end of the traction bridge 10, which is also the rear end of the production line, insert the front ends of all longitudinal bars into the jacks 332 of the longitudinal bar clamping tooling 33, and fix them through the locking parts.

[0052] S2. The previous process (i.e., the welding process) performs the welding operation of the first stirrup cage and the longitudinal bars. After completing the welding of the first stirrup cage and the longitudinal bars, driven by the traction drive motor 312, the traction cross beam 32 and the longitudinal bar clamping tooling 33 move forward along the traction longitudinal beam 11 by a stirrup spacing (this spacing is the designed spacing between adjacent stirrups of the finished steel bar cage 40 of the box girder) synchronously, thereby driving the entire semi-finished steel bar cage forward by a stirrup spacing. At this time, the front end of the semi-finished steel bar cage moves from the previous process to the finished product conveyor line.

[0053] S3. The previous process then performs the welding operation of the second stirrup cage and the longitudinal bars. After completing the welding of the second stirrup cage and the longitudinal bars, under the coordinated action of the finished product traction mechanism 30 and the finished product conveyor line, the entire semi-finished steel bar cage is driven forward by a stirrup spacing;

[0054] S4. Repeat the operation of step S3 for the welding of the next stirrup cage and the longitudinal bars until all the stirrup cages and the longitudinal bars are welded to form the finished steel bar cage 40. At this time, the entire finished steel bar cage 40 is located on the finished product conveyor line, and the finished product traction mechanism 30 is located at the rightmost end (i.e., the front end) of the traction bridge 10.

[0055] S5. The longitudinal bar clamping tooling 33 releases all the longitudinal bars and separates the finished product traction mechanism 30 from the finished steel bar cage 40. The finished steel bar cage 40 can be transported to the target position by using the finished product transportation line 20.

[0056] The finished product feeding device for the production of the steel bar cage of the highway precast box girder provided by the present utility model can realize the automatic feeding of the longitudinal bars according to the production rhythm of the previous process, thereby completing the production and transportation of the finished steel bar cage 40; compared with the manual operation mode, the automatic solution greatly improves the production efficiency.

[0057] The above is only the preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as the protection scope of the present utility model.
