The invention provides a transportation device and a transportation method for loading and transporting heavy equipment. The transportation device comprises two modular self-traveling type flat cars, a portal frame and slings, wherein the slings are mounted on the portal frame; the portal frame comprises a transverse beam and supporting legs which are connected to two ends of the transverse beam; the supporting leg at one end of the transverse beam is detachably mounted on one of the modular self-traveling type flat cars, and the supporting leg at the other end of the transverse beam is detachably mounted on the other modular self-traveling type flat car. The transportation device and the transportation method have the beneficial effects that the modular self-traveling type flat cars are organically combined with the portal frame to form a set of practical construction devices and methods; the transportation device is short in assembly time, small in occupied space, high in loading capacity and high in loading and transporting efficiency for site transfer operation of a precast concrete box girder.
Description
technical field [0001] The invention relates to the field of heavy transport, in particular to a transport device and method for transporting heavy equipment. Background technique [0002] In the prior art, the commonly used methods for transporting heavy prefabricated concrete parts at port wharves include the airbag roll-on method, the special pulley sliding method, the jack+hydraulic flatbed truck shipment method, and the special equipment shipment method. For example: the prefabricated concrete box girder in the offshore bridge weighs 100t to 1000t and needs to be transferred from the prefabrication yard to the wharf for shipment. Currently, there are special transfer methods such as beam transport vehicles and beam lifting machines. [0003] For the on-site transfer operation of precast concrete box girders, a special beam lifting machine is currently used to lift the box girder off the ground, and the beam lifting machine will move the box girder to the designated posi...
