Description

Technical Field

[0001] The utility model relates to the technical field of steel structure transportation, in particular to a transport vehicle for an ultra-wide and ultra-long truss. Background Art

[0002] Conventional hoisting operations for steel structures involve transporting components to the hoisting area, and then using lifting machinery to hoist a single component; or assembling components into trusses or frames for hoisting. When site conditions are limited, the assembly area and the hoisting area are far apart, and direct hoisting is not possible, so flatbed trucks are often required for transportation. Because the maximum plane size of a conventional flatbed truck is 17.5m*2.5m, trusses with larger plane sizes can only be assembled and transported in sections. For some large-span trusses, they need to be assembled and hoisted in multiple sections, and corresponding support measures and safety measures need to be added accordingly, which greatly increases construction costs and installation risks. How to solve the transportation problem of trusses with larger plane sizes to reduce construction costs and safety hazards has become a technical problem that needs to be solved urgently.

[0050] Step 2: Add a bracket beam to the front axle and rear axle of a 13m flatbed truck. Add two connecting plates at 1 / 3 of the width of the front axle of the flatbed truck and hinge them with the bracket beam through bolts, and do the same for the rear axle.

[0051] Step 3: Take another 13m flatbed truck, remove the front of the truck and keep only the 13m trailer at the rear. Add a bracket beam to the front and rear axles of the flatbed truck, add two connecting plates at 1 / 3 of the width of the front axle of the flatbed truck and hinge them with the bracket beam through bolts. The rear axle is processed synchronously.

[0052] Step 4: Place the truss transport vehicle at the designated location, move the flatbed vehicle in front of the truss transport vehicle, and flexibly adjust the distance between the two vehicles according to the length of the truss to realize the transportation of trusses of different plane sizes.

[0053] Step 5: Lift the truss onto the transport vehicle, place it in the center and secure it, then transport the truss to the next construction area.

[0054] Step 6: After the truss is hoisted, the connection between the bracket beam and the flatbed truck can be released. The flatbed truck can be used to transport the bulk components. It is simple to disassemble and easy to use.

[0055] From the above construction process, it can be seen that the transport vehicle of the utility model can flexibly adjust the distance between the front and rear flatbed vehicles according to the actual length of the truss, so as to realize the transportation of multi-specification trusses with larger plane sizes, thereby reducing construction costs and reducing safety hazards. The bracket beam on the flatbed vehicle is easy to disassemble, and the disassembly does not affect the secondary use of the flatbed vehicle.
