The invention discloses a lifting type stand. The lifting type stand is arranged in a hole formed in the ground; a cover plate is arranged at the top of the hole in a sliding manner; hydraulic cylinders are fixed to the periphery of the bottom of the hole; the top ends of the hydraulic cylinders are connected with a supporting plate; multiple steps and a lifting mechanism are arranged at the top of the supporting plate; the multiple steps have a first horizontal state and a second state that the multiple steps are unfolded to form steps; connecting rod assemblies are symmetrically arranged on the two sides of the multiple steps; the lifting mechanism comprises X-shaped shear fork connecting rods symmetrically arranged on the two sides of the supporting plate and a lifting drive mechanism; the lifting drive mechanism is in drive connection with the bottom ends of the shear fork connecting rods; and the shear fork connecting rods are driven to be opened or closed so that the multiple steps can ascend or descend. The lifting type stand is simple in structure and convenient to use, the stand ascends to the use height during use and descends to the lowest height when not used, the stand is stored in the hole in the ground, and the occupied area is saved.
本发明公开了一种升降式看台，设置在地面上开设的孔洞中，孔洞的顶部滑动设置有盖板，孔洞的底部四周固定有液压缸，液压缸的顶端连接有支撑板，支撑板的顶部安装有多级的台阶和升降机构；多级台阶具有呈水平的第一状态以及展开成为阶梯的第二状态；多级台阶的两侧对称设置有连杆组件，升降机构包括对称设置在支撑板两侧的X形的剪叉连杆和升降驱动机构，升降驱动机构与剪叉连杆的底端驱动连接，通过驱动剪叉连杆打开或闭合使多级台阶的上升或下降；本发明结构简单，使用方便，使用时上升至使用高度，不使用时下降至最低高度，并收纳在地面的孔洞中节省了占地面积。
