Movable crawling ladder and engineering vehicle
The invention relates to the technical field of crawling ladders, and discloses a movable crawling ladder and an engineering vehicle, the movable crawling ladder comprises a first crawling ladder section and a second crawling ladder section, and the second crawling ladder section and the first crawling ladder section are connected through a rotating structure; the rotating structure comprises a first stopping structure and a second stopping structure which are arranged between the first crawling ladder section and the second crawling ladder section, and the first stopping structure is used for limiting the second crawling ladder section to be in a use state that a first included angle is formed between the second crawling ladder section and the first crawling ladder section; the second stopping structure is used for limiting the second ladder stand section to be in a storage state in which a second included angle is formed between the second ladder stand section and the first ladder stand section. According to the ladder stand disclosed by the invention, the first stop structure is used for limiting when the second ladder stand section is lowered, and the second stop structure is used for limiting when the second ladder stand section is lifted, so that bidirectional limiting of lowering and lifting of the ladder stand is realized, the ladder stand can be stably taken, placed and used, and the problem that a movable ladder stand is inconvenient to use is solved.
本发明涉及爬梯技术领域，公开了活动爬梯及工程车辆，活动爬梯包括第一爬梯段和第二爬梯段，第二爬梯段和第一爬梯段之间通过转动结构连接；转动结构包括设于第一爬梯段和第二爬梯段之间的第一止挡结构和第二止挡结构，第一止挡结构用于将第二爬梯段限位于与第一爬梯段之间呈第一夹角的使用状态，第二止挡结构用于将第二爬梯段限位于与第一爬梯段呈第二夹角的收纳状态。本发明通过第一止挡结构，起到第二爬梯段下放时的限位，通过第二止挡结构，起到第二爬梯段抬起时的限位，从而实现爬梯的下放、抬起的双向限位，从而能够稳定取放和使用爬梯，解决了活动爬梯使用不便的问题。
