The invention discloses a three-stage extension platform, belongs to the lifting working platform technology, and aims to solve the problems that the existing extension platform can only extend by 1-2 stages, and is difficult to consider a smaller volume in a folded state and a larger activity range in an extended state. By arranging the fixed platform, the first-stage platform movably assembled on the fixed platform, the second-stage platform movably assembled on the first-stage platform and the third-stage platform movably assembled on the second-stage platform, the first-stage platform is dragged by the driving device through the steel wire rope to move at the same speed relative to the fixed platform and the second-stage platform relative to the first-stage platform; the third-stage platform moves relative to the second-stage platform through manual operation, three-stage extending and folding are achieved, and the use requirement is met. And when the first-stage platform, the second-stage platform and the third-stage platform are folded to the fixed platform, the occupied space is small, storage is facilitated, and meanwhile the large movement range of the extending state is taken into account.
本发明公开了一种三级延伸平台,属于升降工作平台技术,现有延伸平台仅能延伸1‑2级,难以兼顾收拢状态的较小体积和延伸状态的较大活动范围,本发明通过配置固定平台、移动装配于固定平台的一级平台、移动装配于一级平台的二级平台以及移动装配于二级平台的三级平台,由驱动装置经钢丝绳牵引着一级平台相对于固定平台及二级平台相对于一级平台以同样的速度移动,通过手动操作实现三级平台相对于二级平台的移动,实现三级延伸和收拢,满足使用要求。而且一级平台、二级平台和三级平台收拢至固定平台时占据空间小,利于储存,同时兼顾了延伸状态的较大活动范围。
