Longitudinal and transverse beam system for suspension type monorail hyperbolic curve track beam
The invention discloses a longitudinal and transverse beam system for a suspension type monorail double-curve track beam, which comprises track beams on two sides and is characterized in that a longitudinal beam is arranged between the track beams on the two sides along a central line, two ends of the longitudinal beam are connected with upright posts, and the track beams on the two sides are suspended on two sides of the upright posts, and a plurality of cross beams are arranged along the longitudinal direction to connect the longitudinal beams and the two side track beams into a whole. The cross beam can adopt an I-shaped or box-shaped cross section. The section of the suspension type track beam is of a thin-wall steel structure with an opening in the bottom, an inner cavity is reservedfor electromechanical equipment and a vehicle to walk, a stiffening structure cannot be arranged, and therefore torsional rigidity is small. The longitudinal and transverse beam system can restrain the bending deformation of the left and right track beams of the curve section, so that the structure is stressed uniformly and the deformation is coordinated, the vertical displacement and torsion angle of the track beams are greatly reduced, the applicable span of the curve track beams is increased, and the smoothness and comfort of a train running on the curve section are improved.
本发明公开一种用于悬挂式单轨双线曲线轨道梁的纵横梁体系，包括两侧轨道梁，其特征在于在两侧轨道梁之间，沿中心线设置一根纵梁，纵梁的两端与立柱相接，两侧轨道梁悬挂于所述立柱的两侧，沿纵向设多道横梁将纵梁与两侧轨道梁连接成整体。横梁可采用工字形或箱形截面。悬挂式轨道梁截面为底部开口的薄壁钢结构，内腔预留给机电设备及车辆走行，不能设置加劲结构，因此抗扭刚度较小。本发明的纵横梁体系可约束曲线段左、右线轨道梁的弯扭变形，使结构受力均匀，变形协调，从而大幅减小轨道梁的竖向位移和扭转角，增加曲线轨道梁的适用跨径，提高列车在曲线段行驶的平顺性和舒适性。
