Problems solved by technology

The width of the high-speed rail line only allows beam-carrying vehicles to pass in one direction. It is a wrong-way traffic. A certain section of roadbed can be widened as a meeting point. The disadvantage is that the land acquisition and construction costs are high, and the meeting place cannot be changed.

Embodiment 1

[0043] 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.

[0044] 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...

Embodiment 2

[0055] 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:

[0056] 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.

Abstract

The invention relates to a lifting device for meeting of beam transport cars on a bridge and a meeting method. The lifting device comprises two gantry structures arranged on the bridge in the longitudinal bridge direction, a plurality of connecting beams used for connecting the two gantry structures, and two lifting systems respectively arranged in the two gantry structures and used for hoisting the no-load beam transport car. The meeting method comprises the steps that the lifting device is utilized to lift the no-load beam transport car to a high position, then the heavy-load beam transportcar passes below the no-load beam transport car, and accordingly meeting on the bridge is completed.

Description

technical field [0001] The invention relates to the technical field of railway bridge construction, in particular to a lifting device and a method for meeting vehicles on bridges. Background technique [0002] In high-speed rail lines, bridges account for a considerable proportion. High-speed rail bridges generally adopt the most economical construction mode of beam field prefabrication, beam truck transport, and bridge frame girders. The land acquisition, construction, recultivation, and equipment investment of the box girder prefabrication yard cost a lot of money. In order to save construction costs, the distance between the box girder prefabrication yards is relatively large, so that the time of beam transportation becomes the controlling factor of the construction work of the girder erection, reducing the cost. beam erection efficiency. In order to match the efficiency of beam transporting and beam erecting operations, two beam transporting vehicles can be used to supp...
