The invention provides a semitrailer ladder stand, and relates to the field of semitrailers, the semitrailer ladder stand comprises a ladder plate and ladder feet, the front end of the ladder plate is rotatably connected with a carriage, the upper ends of the ladder feet are rotatably connected with the tail end of the ladder plate, the central axis of the ladder plate rotating relative to the carriage is parallel to the central axis of the ladder feet rotating relative to the ladder plate, and the lower surfaces of the ladder feet are perpendicular to the ladder plate. Front sharp corners are arranged on the front sides of the lower surfaces of the ladder feet, and rear sharp corners are arranged on the rear sides of the lower surfaces of the ladder feet. According to the ladder stand, when the ladder feet fall to the ground, no matter whether the ground of the landing position is in a horizontal state or not, the ladder feet can rotate relative to the ladder plates along with landing until the lower surfaces of the ladder feet are flush with and attached to the ground, and the problem that in the prior art, when the landing position of the tail end of the ladder stand is in an inclined state, the ladder feet cannot rotate is solved. And the tail end of the crawling ladder is easy to damage and hinders goods from going up to the ladder.
本申请提供了一种半挂车爬梯,涉及半挂车领域,其梯板、梯脚,梯板的前端与拖板转动连接,梯脚的上端与梯板的末端转动连接,梯板相对拖板旋转的中心轴线平行于梯脚相对梯板旋转的中心轴线,梯脚的下表面与梯板垂直,梯脚下表面的前边设有前尖角,梯脚的下表面后边设有后尖角。采用本申请的爬梯,梯脚落地时,无论落地位置的地面是否处于水平状态,梯脚也能够随着着地而相对梯板旋转至下表面与地面平齐贴合,解决了现有技术中爬梯末端落地位置处于倾斜状态时,爬梯末端容易发生损坏并对货物上梯构成阻碍的技术问题。
