The depressed center flatcar structure comprises a depressed center frame (1) and two walking parts (2), hollow structures (1a) are arranged at the two ends of the depressed center frame (1), and the lower ends of the hollow structures (1a) are open; each lifting device comprises a center plate component (3) and a driving component (4), the lower end of each center plate component (3) is supported on the corresponding walking part (2), the upper end of each center plate component (3) is longitudinally inserted into the corresponding hollow structure (1a) in a limiting manner, each driving component is fixed at the upper end of the concave bottom frame (1) and is provided with an output shaft, and the output shafts can penetrate through the concave bottom frame (1); therefore, the center plate component (3) abuts against the base plate component (2). According to the depressed center flatcar structure, the hollow structures are arranged at the two ends of the depressed center frame, and the upper end of the center plate component is longitudinally limited and inserted into the hollow structures, so that the center plate component bears longitudinal load, and driving safety is guaranteed.

    本发明公开一种凹底平车结构,包括凹底架(1)和两个走行部(2),凹底架(1)两端设置有中空结构(1a),中空结构(1a)下端开口;还包括两个升降装置,升降装置包括心盘部件(3)和驱动部件(4),心盘部件(3)的下端支撑于对应的走行部(2),心盘部件(3)的上端纵向限位插装于对应的中空结构(1a)内部,驱动部件固定于凹底架(1)上端,驱动部件具有输出轴,输出轴能够穿过凹底架(1),以与心盘部件(3)抵接。本发明凹底平车结构,在凹底架两端设置中空结构,并将心盘部件的上端纵向限位插装于中空结构内部,从而由心盘部件来承受纵向载荷,保证行车安全。
