[0035] Please refer to Figures 1 to 4 A precast beam hydraulic formwork conversion system includes a side formwork 1, several groups of formwork rails and several pedestals 2. The side formwork 1 can move along the formwork rails. Several of the formwork rails are arranged in parallel. Several of the pedestals 2 are distributed between the formwork rails. The formwork rails include a first rail 31. The first rail 31 is arranged between two adjacent pedestals 2. The first rail 31 is configured with three formwork monorails 311.

[0036] When arranging the same number of production lines, in order to reduce the width of the construction site, and the present invention can increase the number of pedestals 2 arranged horizontally in a roadbed prefabrication plant with limited width, thereby improving the utilization rate of the construction site, the present technical solution arranges a precast beam hydraulic formwork conversion system including a side formwork 1, several groups of formwork tracks and several pedestals 2, the side formwork 1 is equipped with a walking mechanism, the walking mechanism includes walking wheels, a motor and a transmission mechanism, the formwork monorail 311 is a steel rail, and the side formwork 1 travels along the formwork monorail 311 through the walking wheels. In the present technical solution, the mold transport track includes a first track 31 and a second track 32. The first track 31 is arranged between two adjacent pedestals 2. The first track 31 includes three mold transport monorails 311. The second track 32 is composed of two mold transport monorails 311. For a pedestal 2 having only one side adjacent to the adjacent pedestal 2, the present technical solution arranges a first track 31 including three mold transport monorails 311 on one side of the pedestal 2, and arranges a second track 32 including two mold transport monorails 311 on the other side of the pedestal 2. The track gauge of the two adjacent mold transport monorails 311 in the first track 31 is equal to the track gauge of the second track 32. The technical solution arranges a first track 31 including three mold transport monorails 311 between two adjacent pedestals 2, that is, the mold transport monorail 311 in the middle position of the three mold transport monorails 311 is a common monorail. Compared with the prior art, the spacing occupied by the tracks between two adjacent pedestals 2 is reduced. When the same number of production lines are arranged, the present invention can achieve the purpose of reducing the width of the construction site. Moreover, for a roadbed prefabrication plant with limited width, the present invention can increase the number of pedestals 2 arranged laterally in a limited area and improve the utilization rate of the construction site by reducing the spacing occupied by the tracks between two adjacent pedestals 2.

[0037] In some embodiments, a template transverse movement area 41 is further included. A template transverse movement device is disposed in the template transverse movement area 41 . The template transverse movement device is connected to the first track 31 . The template transverse movement device is used for changing the side template 1 between different first tracks 31 . In the technical solution, the distribution area of ​​the pedestal 2 is the production area 5, and a template transverse movement area 41 is provided at one end of the first track 31. A template transverse movement device is arranged in the template transverse movement area 41, and the template transverse movement device includes a transverse movement track 421 and a transverse conversion vehicle 423. The transverse movement track 421 is arranged vertically with the first track 31, and the transverse movement track 421 and the first track 31 are arranged in a grid. The transverse movement track 421 is composed of two steel rails. The track gauges of the transverse movement track 421 and the second track 32 are equal. Different first tracks 31 are connected through the transverse movement track 421, and the first track 31 and the second track 32 are also connected through the transverse movement track 421. The transverse conversion vehicle 423 is arranged on the transverse movement track 421, and the transverse conversion vehicle 423 is used to lift and transversely move the side template 1. The transverse conversion vehicle 423 is equipped with a lifting hydraulic cylinder, and after the lifting hydraulic cylinder is lifted, the lifting hydraulic cylinder abuts against the side template 1. When it is necessary to transfer the side formwork 1 from the current first track 31 to another first track 31, the side formwork 1 is moved along the current first track 31 from the production area 5 to the template transverse movement area 41, and then the transverse conversion vehicle 423 is moved to the bottom of the side formwork 1, and the lifting hydraulic cylinder is extended to lift the side formwork 1 as a whole, so that the side formwork 1 is separated from the current first track 31, and then the transverse transfer vehicle carries the side formwork 1 to the target first track 31, and then the lifting hydraulic cylinder is retracted to place the side formwork 1 as a whole on the target first track 31, and then the transverse transfer vehicle is separated from and moves away from the side formwork 1, and the side formwork 1 is moved along the target first track 31 from the template transverse movement area 41 to the production area 5. In the prior art, due to the large change in the beam type of prefabricated beams, the side beams and the middle beams need to be changed and prefabricated, and the number of pedestals 2 is small, which makes the cost of hydraulic formwork very uneconomical compared with large sites. In the prior art, if the beam type needs to be changed, the conventional practice is to add a side formwork 1 to the original production line, or to remove the hydraulic formwork and transfer it through a gantry crane, which leads to increased costs, and due to the process of adjusting the elevation of the line and the template, the removal process and installation are troublesome. In this technical solution, different beam types refer to side beams, middle beams, high side beams and bottom side beams. Changing the beam type in prefabrication production refers to the conversion from side beams to middle beams, high side beams or bottom side beams. This technical solution can convert the side formwork 1 for any production line by setting a template transverse movement device, so as to achieve a fast and dismantling-free line change combination without the need for gantry crane cooperation. In the production area 5, under the premise of meeting the production capacity, only the minimum number of side formworks 1 need to be arranged in the entire production area 5, and the side formworks 1 of different beam types also require the minimum number of side formworks 1. The side formworks 1 can be converted between any production lines through the template transport track and the template transverse movement device.

[0038] In some embodiments, a template turning device is further included, which is arranged in the template transverse movement area 41 and is used to rotate the side template 180°. The template turning device includes a central turntable 431, a circular track 432 and a turning conversion vehicle 433. The central turntable 431 is arranged at the center of the circular track 432, and the central turntable 431 abuts against the middle of the side template 1. The central turntable 431 is used to support the side template 1. The turning conversion vehicle 433 can move along the circular track 432. The turning conversion vehicle 433 is detachably connected to the side template 1 and is used to drive the side template 1 to rotate around the central disk. The central disk is equipped with a central lifting hydraulic cylinder. The template transverse shifting device can only realize the translational change of the side template 1 between different first tracks 31, and a set of side templates 1 includes two left and right side templates 1. When the left and right side templates 1 need to be interchanged, the technical solution sets a template turning device including a center turntable 431, a circular track 432 and a turning conversion vehicle 433 in the template transverse shifting area 41. The center turntable 431 is set as a center lifting hydraulic cylinder to realize the interchange of the left and right side templates 1. When it is necessary to replace the side template 1, taking the left side template 1 as an example, the left side template 1 is moved from the production area 5 to the template transverse movement area 41 along the current first track 31, and the transverse transfer vehicle moves the left side template 1 to the center disk, and the center lifting hydraulic cylinder of the center lifting hydraulic cylinder extends out, and the center lifting hydraulic cylinder abuts against the middle part of the left side template 1, lifts the left side template 1 as a whole, so that the left side template 1 is separated from the transverse transfer vehicle, and the transverse transfer vehicle is moved away. Two U-turn conversion vehicles 433 are respectively connected to the two ends of the left side template 1, and the two U-turn conversion vehicles 433 are used to drive the center disk to rotate 180°, and then the U-turn conversion vehicle 433 is separated from the left side template 1, and the center lifting hydraulic cylinder retracts, so that the original left side template 1 is put back on the track, and then the original left side template 1 is moved to the target first track 31 by the transverse transfer vehicle.

[0039] It should be noted that the U-turn conversion vehicle 433 has a similar structure to the lateral transfer vehicle. The U-turn conversion vehicle 433 is equipped with a lifting hydraulic cylinder. When it is necessary to be detachably connected to the side formwork 1, the hydraulic cylinder is lifted, and the hydraulic cylinder is used to realize the detachable connection between the U-turn conversion vehicle 433 and the side formwork 1. When it is necessary to release the connection with the side formwork 1, the hydraulic cylinder is retracted.

[0040] In some embodiments, the mold transport track also includes a return track 33, which is connected to the template transverse movement device. In order to increase, decrease or replace the template 1 inside the production area 5, the technical solution is provided with a return track 33, which is connected to the transverse movement track 421, and can be moved from the first track 31 to the return track 33 by a transverse transfer vehicle, or from the return track 33 to the first track 31 by a transverse transfer vehicle.
