Embodiment Construction
[0061] like figure 1 , figure 2 , image 3 and Figure 4 As shown, the reverse pulling device used for the pulling construction of large-span steel truss girder includes a temporary support and a hoist 1. The temporary support is provided with a slideway 2 whose cross section is in the shape of a groove. The crawler-type transporter 3 moved by the road 2, the steel truss girder 4 is set on the crawler-type transporter 3, the hoist 1 is set on the steel truss girder 4, the upper part of the front end of the temporary support is provided with a fixed pulley block 5, and the hoist 1 is wound on The traction rope 7 bypasses the fixed pulley block 5 and is connected to the front end of the steel truss beam 4 through a movable pulley block 6 .
[0062] The temporary support includes a steel pipe column 8, an I-beam distribution beam 9, a Bailey beam 10, a shaped steel sleeper 11 and a drag track beam 12, which are arranged in sequence from bottom to top. Bailey Beam 10 on.
