The invention relates to the technical field of special vehicles for hot-line work, in particular to a crawling ladder for a vehicle and an insulating bucket arm vehicle. The vehicle ladder stand comprises a fixed ladder section and a movable ladder section, the fixed ladder section is used for being fixed to a vehicle body, the movable ladder section is hinged to the lower end of the fixed ladder section around the horizontal axis, the vehicle ladder stand further comprises an overturning driving mechanism used for driving the movable ladder section to conduct overturning action around the hinge axis, and the movable ladder section has an unfolding position and a folding position in the moving stroke of the movable ladder section. The movable ladder section is provided with a treading structure, the treading structure is located on the lower side of the hinge axis when the movable ladder section is located at the unfolding position, and the treading structure is located on the upper side of the hinge axis when the movable ladder section is located at the folding position. During getting on and off, the movable ladder section is driven by the turnover driving mechanism to turn downwards to the unfolding position, so that the treading structure of the movable ladder section is close to the ground, and getting on and off are facilitated; when the vehicle ladder stand is not used, the movable ladder section is driven by the overturning driving mechanism to be overturned upwards to a retracting position, so that the vehicle ladder stand is far away from the ground, and the vehicle trafficability is prevented from being influenced.
本发明涉及带电作业专用车辆技术领域,尤其涉及一种车用爬梯和绝缘斗臂车。车用爬梯包括固定梯段和活动梯段,固定梯段用于固定到车体上,活动梯段绕水平轴线铰接在固定梯段下端,车用爬梯还包括用于驱动活动梯段绕铰接轴线作翻转动作的翻转驱动机构,活动梯段在其活动行程内具有展开位和收起位,活动梯段具有踩踏结构,在活动梯段处于展开位时踩踏结构处于铰接轴线下侧,在活动梯段处于收起位时踩踏结构处于铰接轴线上侧。上下车时通过翻转驱动机构驱动活动梯段向下翻转至展开位,使活动梯段的踩踏结构离地较近,便于上下车;不使用时通过翻转驱动机构驱动活动梯段向上翻转至收起位,使车用爬梯离地较远,从而避免对车辆通过性造成影响。
