Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a box beam supporting moving device. Background Art

[0002] Box girder is a type of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box, hence the name. During the installation of the bridge, multiple box girders need to be spliced ​​together to form the frame of the bridge. When splicing the box girders, temporary brackets are usually installed at the bridge first, and rails are set on the temporary brackets. A box girder support moving device is set on the rails to transport the box girder and pull the box girder along the rails to the specified position; the position where the box girder support moving device is connected to the contact is the support surface of the box girder, and the support surface of the box girder is generally an inclined surface. In order to make the box girder support device and the box girder fit better, the top of the box girder support moving device is generally set to an inclined surface that matches the box girder, but the inclination angles of the support surfaces of different box girders are different, so it is necessary to make multiple types of box girder support moving devices to match different types of box girders. The increase in the specifications of the box girder support moving device will make the matching process cumbersome and complicated, resulting in an increase in construction costs.
