Example (b):

as shown in fig. 1-3, a common rail and wrong rail combining device for a gantry crane tool in a large precast beam plant comprises an operation plane 1, wherein first travelling rails 2 are arranged on two sides of the operation plane 1, second travelling rails 3 are arranged on opposite sides of the two groups of first travelling rails 2, a plurality of groups of first pedestals 4 are sleeved in the first travelling rails 2, a plurality of groups of second pedestals 5 are sleeved in the second travelling rails 3, first gantry frames 6 are fixed at the top ends of the groups of first pedestals 4, second gantry frames 7 are fixed at the upper ends of the groups of second pedestals 5, movable bins 8 are arranged at the top ends of the second gantry frames 7 and the movable bins 8, and hoisting mechanisms 9 are movably arranged in the movable bins 8;

the first portal frame 6 which is out of the beam and has a large hoisting height is arranged on the outer side, and the second portal frame 7 which is used for prefabrication production and has a small hoisting height is arranged on the inner side, so that the hoisting weight can be strictly ensured when the portal cranes are in a common rail, and various hoisting modes are met; and the gantry crane can flexibly carry out cross construction in the rail-staggering process, hoisting tasks of all procedures are closely linked, and the gantry crane and the hoisting tasks are combined, so that the utilization rate of the gantry crane is greatly improved, and high-efficiency flow line production is formed.

In other embodiments, the span between the two first running rails 2 is 25.5 meters, the span between the two second running rails 3 is 20 meters, and the two first running rails 2 and the two second running rails 3 are both designed in parallel;

through the design, the safety of longitudinal movement of the gantry crane is improved, and the cross construction forms a flow process surface, so that the efficient connection of the prefabricating process is promoted, the beam making period is greatly shortened, and the yield is also improved.

In other embodiments, the lifting height of the plurality of groups of first portal frames 6 is 12 meters, and the lifting height of the plurality of groups of second portal frames 7 is 9 meters;

through the design, the hoisting gantry cranes with different hoisting heights of a plurality of groups do not influence the production of wrong rails when the gantry cranes are out of the beam, and the gantry cranes can conveniently install and disassemble the templates of the precast beams, insert the steel reinforcement frameworks into the mold and pour concrete.

In other embodiments, the sets of first gantries 6 are not in common with the sets of second gantries 7;

through the design, the gantry cranes in the first travelling crane track 2 and the second travelling crane track 3 can be subjected to cross construction, unnecessary avoidance time between the gantry cranes is effectively reduced, and the construction efficiency is improved.
