The invention discloses a concave underframe and container transportation equipment, belongs to the technical field of transportation equipment, and aims to solve the technical problem that an existing concave underframe is poor in reliability. The depressed center frame comprises a connecting part and two side walls, the two side walls are oppositely arranged, each side wall comprises an upper side beam, a lower side beam and a stand column, the upper side beams and the lower side beams are oppositely arranged, the two ends of the stand columns are hinged to the upper side beams and the lower side beams respectively, and the two ends of the connecting part are connected with the lower side beams of the two side walls respectively. The upper side beam, the lower side beam and the stand column are connected in a hinged mode, so that a certain rotational degree of freedom exists between the lower side beam and the stand column, and a certain rotational degree of freedom also exists between the upper side beam and the stand column. The rotational degree of freedom among the upper side beam, the lower side beam and the stand column can release at least part of external force so as to prevent the joints of the upper side beam, the lower side beam and the stand column from being damaged due to long-term stress.
本申请公开了一种凹底架及集装箱运输设备,属于运输设备的技术领域,以解决目前的凹底架可靠性不佳的技术问题。其中,凹底架包括连接部和两个侧墙,两个侧墙相对设置,侧墙包括上侧梁、下侧梁和立柱,上侧梁和下侧梁相对设置,立柱的两端分别与上侧梁和下侧梁铰接,连接部的两端分别与两个侧墙的下侧梁连接。上侧梁、下侧梁和立柱均通过铰接的方式连接,使得下侧梁与立柱之间具有一定的转动自由度,并使得上侧梁与立柱之间也具有一定的转动自由度,这样当侧墙受到外力作用时,上侧梁、下侧梁和立柱之间的转动自由度可将至少部分外力释放,以防止上侧梁、下侧梁和立柱的连接处长期受力而损坏。
