The precast concrete box girder has a large amount of application in bridge construction industry due to the advantages of high precast quality, high construction speed, good structural integrity, small influence on environment and traffic and the like. At present, a large-scale precast beam field for producing concrete box beams is built and operated by a plurality of domestic enterprises, and due to the large precast quantity of the box beams and the combination of a beam erecting construction organization plan, a large-scale beam storage area needs to be arranged in the field, and under the condition that the length direction of the field is limited, the precast box beams and the beam storage area can only be arranged in parallel and independently in the width direction, and after the precast box beams are finished, the precast box beams need to be transferred from the precast area to the beam storage area for storage.

The traditional box girder transferring process is that a gantry crane lifts the box girder to walk to a box girder traversing area, the box girder is placed on a traversing trolley to be transported to a gantry crane range of a girder storage area, and finally the gantry crane lifts the box girder to be transported to a girder storage pedestal. The traditional box girder transferring process has the following defects: (1) The door machine needs to lift the box girder to walk for a long distance, so that a great amount of operation time of the door machine is occupied by transportation, and meanwhile, the transportation safety risk is increased; (2) The portal crane track and the sideslip track of sideslip dolly carry out the cross arrangement, and sideslip track needs to increase the orbital connecting device of crossing portal crane in the handing-over department, need the manual work to dismantle during the use.

Detailed Description

The present utility model is described in further detail below with reference to the drawings to enable those skilled in the art to practice the utility model by referring to the description.

The following description is presented to enable one of ordinary skill in the art to make and use the utility model. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the utility model defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.

It will be appreciated by those skilled in the art that in the present disclosure, the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc. refer to an orientation or positional relationship based on that shown in the drawings, which is merely for convenience of description and to simplify the description, and do not indicate or imply that the apparatus or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore the above terms should not be construed as limiting the present utility model.
