What do you need to pay attention to when fixing the Bailey beam

The anchoring system of Bailey beam is divided into the anchoring system when the basket is under load and the anchoring system when no load is walking. When the basket is loaded, two rear anchor beams are set at the back end of each side of the main truss, the spacing is 30 ~ 40cm, and each one is set with two anchor points, the center distance of the anchor points is 135cm. The rear anchor boom is used to anchor the anchor beams on the top plate of the box beam and the flange plate. When walking with no load, the back anchor pole is removed, and all the overturning torque is borne by the two sets of reverse buckle wheels on the bottom surface of the top plate of the track.

Due to the different work content, the walking system can be divided into the main truss of the hanging basket and the bottom basket walking mechanism, the inner mold walking mechanism and the outer mold walking mechanism. The main components are track, slide seat, reverse buckle wheel group, suspension wheel, slide beam, the inner mold walking mechanism and traction system. Among them, the track is a steel box composed of steel plates, with sleeper and steel pillow underneath, and each section is anchored with 3 fine rolled thread steel bars embedded in the top surface of the box beam (opening in the belly of the track and anchoring the screw in the box); The sliding seat is made of steel plate, the sliding seat is connected with the main girder by bolts, and the front end is provided with a walking wheel; The reverse buckle wheel group is made of steel plate, cast steel No. 35 is used as the reverse buckle wheel, the top surface is equipped with 20mm thick connecting steel plate, and the main girder is connected with pins and bolts; The suspension wheel is made of steel plate, with No. 35 cast steel as a walking roller for the sliding beam to walk; The sliding beam and the walking mechanism are made of channel steel. Because the hanging basketball team adopts the rolling and moving way, the walking of the hanging basket uses 8t chain hoist traction.
