Embodiment 1
[0044] Such as Figure 1-6 , a folding emergency bridge, which includes a bridge main part, the bridge main part includes a base 1 supported on the ground, and a column 4 is hinged on the base 1; Drive the hydraulic cylinder 2 to rotate, and the other side wall of the column 4 is hinged with a pin shaft to have a foldable bridge deck surface 9, and the bridge deck surface 9 and the side wall of the column 4 are symmetrically arranged The lateral folding frame 6 is hingedly connected, and a wire rope system 5 for providing traction is symmetrically fixed on the top of the column 4, and one of the winding drums of the wire rope system 5 is fixed on the folding frame 6 through the first drum wire rope 8. A plurality of guide wheels 7 on the top are matched, and their ends are connected to the end of the bridge deck surface 9. The other winding drum of the wire rope system 5 is connected to the first section of the bridge deck surface 9 through the second drum wire rope 10. conne...
Embodiment 2
[0057] The using method of a kind of folding emergency bridge described in any one, it comprises the following steps:
[0058] Step1: The transport vehicle 11 carrying the folding bridge is driven to the side of the river where the bridge needs to be erected, and the rear of the car is parked facing the river;
[0059] Step2: Start the hydraulic cylinder 2, and erect the bridge body through the hydraulic cylinder 2. When the column 4 is perpendicular to the ground, the hydraulic cylinder stops working and maintains this state;
[0060] Step3: Unfold all four movable outriggers 3, and activate the outrigger hydraulic cylinder to prop up the entire slow bridge. One end of the bridge deck surface 901 lands;
[0061] Step3: Start the deceleration motor 508, and transmit the rotation movement to the first roller 502 and the second roller 503 through the gear, and slowly stretch the wire rope, and the folding bridge body will unfold forward by its own gravity until the entire bridg...
