 Such as figure 1 A lifting device for moving beams and meeting cars on a bridge is shown, which includes two gantry structures 1, several connecting beams 2, and a lifting system 4 arranged inside the gantry structures 1; the gantry structures 1 It is arranged on the bridge along the longitudinal bridge direction; the connecting beam 2 is used to connect the two gantry structures 1, and the two ends of the connecting beam 2 are fixedly connected with the gantry structure 1 through flanges respectively; the two sets of lifting The lifting system 4 is respectively arranged in the two gantry structures 1, which can reduce the dead weight of the lifting device; the lifting system 4 is used for hoisting the empty beam carrier 300, and lifting the empty beam carrier to a high place or lowering it to bridge deck.
 In this embodiment, two gantry structures 1 are connected by three connecting beams 2, and the three connecting beams are weak connections, which are only u...
 see Figure 13 , Figure 14 as well as Figure 15 , this embodiment discloses a method for moving beams and meeting vehicles on a bridge, including the following steps:
 The meeting point on the bridge between the box girder prefabrication site and the bridge span to be erected is pre-installed with the meeting lifting device as described in Figure Embodiment 1. The vehicle lifting device lifts the empty beam transport vehicle 300 to a high place, and when the heavy beam transport vehicle 400 reaches the meeting point, passes under the empty beam transport vehicle 300 lifted by the meeting vehicle lifting device, and the empty beam transport vehicle 300 passes under the empty beam transport vehicle 300 The car 300 descends to the bridge deck, returns to the box girder precast yard to transport the girders, and completes the car meeting operation on the bridge.
