Problems solved by technology

[0003] In the prior art, the component installation unit transportation of steel truss girder bridges (including girder girder transportation, bridge deck transportation, and construction equipment transportation) is carried out on the steel truss and bridge decks that have been installed in place. Considering the wind load of the bridge area Considering various factors such as engineering investment, construction safety, etc., the bridge deck installed in advance is two independent bridge decks, which do not form a whole. Some unfavorable consequences, the single bridge deck of the installation unit has the risk of structural stability under the construction load of the steel truss member transportation, and there is also a risk of structural deformation, which will affect the transportation of the steel truss member and affect the installation accuracy of the bridge deck. Affect the installation quality of the bridge deck

Embodiment Construction

[0014] Embodiments of the invention. A kind of steel truss girder bridge transport beam flat car, such as figure 1 and 2 As shown, the running mechanism 2 is installed at the bottom of the vehicle frame 1, the bracket 4 for fixing the steel truss member is installed on the vehicle frame 1, and the rotating bracket 5 for stabilizing the steel truss member is installed on the surface of the vehicle frame 1.

[0015] like image 3 As shown, the rotating bracket 5 is connected to the supporting rod 6, and an arc-shaped plate 7 is installed between the rotating bracket 5 and the supporting rod 6. The arc-shaped plate 7 is in contact with the bottom of the steel truss member, and can always maintain a contact surface with the bottom of the steel truss member on the vehicle frame 1 when the bridge deck has a slope change and the bridge deck also has a knuckle.

[0016] A link mechanism 3 for adjusting the length of the vehicle frame 1 is installed between the running gear 2 to mat...

Abstract

The invention discloses a beam-transporting flatcar for a steel truss bridge. The beam-transporting flatcar is characterized in that a traveling mechanism (2) is arranged at the bottom of a vehicle frame (1); a support (4) for fixing a fixed steel truss component is arranged on the vehicle frame (1); and a rotation support (5) for stabilizing the steel truss component is arranged on the surface of the vehicle frame (1). By utilizing the beam-transporting flatcar, the following effects can be realized: various kinds of components are transported; the beam-transporting flatcar is used for transportation under various longitudinal slope and variable slope conditions; the components with various lengths can be transported by connecting two independent trolleys by a connecting rod; and long-distance transportation can be realized by an electric appliance system of the traveling mechanism without arranging cable lines along the line.
