The invention discloses an extension ladder with a limiting and locking mechanism and engineering machinery. The extension ladder comprises a ladder frame, a slide and the limiting and locking mechanism, the ladder frame is mounted on a channel device of the engineering machinery; the slide is mounted in the ladder frame and can slide up and down in the ladder frame; the limiting and locking mechanism is installed between the ladder frame and the slide and can limit and lock the slide at the highest position. An extension ladder is arranged on a large engineering machine and used for a person to climb the vehicle, after the person enters a cab from the ground through the extension ladder, the person needs to lift a slide of the extension ladder to the position above the rotation face of the machine and then lock the slide, and after locking, the whole vehicle can run and work.

    本发明公开了一种具有限位锁止机构的伸缩梯及工程机械,包括梯子框架、滑梯和限位锁止机构;梯子框架安装在工程机械的通道装置上;滑梯安装在所述梯子框架中,该滑梯能够在梯子框架中上下滑动;限位锁止机构安装在所述梯子框架与滑梯之间,能够对滑梯在最高位置时进行限位和锁止。在大型工程机械上,设置有伸缩梯用于人员攀爬登车,人员通过伸缩梯从地面进入到驾驶室后,需把伸缩梯的滑梯升到机器回转面之上,然后把滑梯锁止,锁止后整车才能运行并进行作业。
