The invention discloses a crawling ladder structure movably connected to a tank truck and a crawling ladder thereof. The crawling ladder structure comprises an upper support, wherein the upper supportcomprises an upper support base plate and an upper support vertical plate, the upper support base plate is connected to a tank assembly, and the upper portion of the upper support vertical plate is provided with a rotation shaft hole; and a movable support pipe, wherein the upper portion of the movable support pipe is connected with a crawling ladder pipe, the movable support pipe further comprises a lower installation hole formed in the lower portion of the movable support pipe, and the rotation shaft hole and the lower installation hole are connected in the mode that an upper support installation bolt penetrates into the rotation shaft hole to be matched with a rotation shaft. The crawling ladder structure and crawling ladder have the beneficial effects that rigid connection of the crawling ladder and the tank body is improved into movable connection, the assembly stress between the tank body and the lower vehicle body can be fully absorbed, the phenomenon that the crawling ladder is locally cracked due to stress generated by distortion of the vehicle body under complex road conditions is avoided, the use strength of the crawling ladder is improved, and the service life of the crawling ladder is prolonged.

    本发明公开了一种液罐车上活动联接的爬梯结构及其爬梯,包括上支座,其包括上支座底板和上支座竖板,所述上支座底板与罐体总成连接,所述上支座竖板的上方设置有转轴孔;活动支座管,其上方与爬梯管连接,所述活动支座管还包括设置于其下方的下安装孔,所述转轴孔与所述下安装孔间通过穿入上支座安装螺栓配合转轴连接。本发明的有益效果:通过将爬梯和罐体的刚性联接改进为活动联接,可以充分吸收罐体和下车体之间装配应力,避免复杂路况下的车身扭曲变形产生的应力造成爬梯局部开裂现象,增加爬梯的使用强度以及延续爬梯的使用寿命。
