Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, during high-order beam transportation vehicle transportation box beam, case beam is contained in and carries out fortune dress at front end buttress 5 with carrying on the back on beam dolly 6, but when crossing tunnel, catenary mast 13 can touch tunnel inner wall, therefore needs high-order beam transportation vehicle to be transformed into low level beam transportation vehicle.
A kind of method utilizing high-order beam transportation vehicle to transform low level beam transportation vehicle of the present invention, comprises the following steps: A, removed by beam transportation vehicle front end buttress 5, replaces with rubber pad 7; B, vehicle frame both sides install jacking cylinder 9; C, beam trolley track will be carried on the back extend to rear operator's compartment 4 place, and dodge and carry on the back on beam trolley track by carrying beam dolly 6 on the back to rear operator's compartment 4 place; D, on vehicle frame 1 carrying case beam, rubber pad 7 is set between case beam and vehicle frame; After E, shipment put in place, jacking cylinder 9 coordinates with hanging beam before Bridge Erector the case beam that hoists, and reaches after carrying beam dolly reset height on the back, carries beam dolly 6 reset on the back and starts program of normally setting a roof beam in place.
According to one embodiment of present invention, the method utilizing high-order beam transportation vehicle to transform is:
1, beam transportation vehicle front end buttress 5 is removed, replace with rubber pad 7;
2, install between 19 ~ 21 groups, 20 ~ 22 groups wheels when jacking cylinder 9(loads and transports 24m case beam and use); When loading and transporting 32m case beam, jacking cylinder 9 is installed between 27 ~ 29 groups, 28 ~ 30 groups wheels; This jacking cylinder coordinates with hanging beam before Bridge Erector the case beam that hoists, and reaches after carrying beam dolly reset height on the back, carries the reset of beam dolly on the back and starts program of normally setting a roof beam in place.
