The invention provides a lifting trolley. The lifting trolley comprises a base, the first stand column is fixed to the base and provided with a containing cavity; at least part of the second stand column is located in the containing cavity and slidably assembled on the first stand column in the axial direction of the first stand column, and the second stand column is provided with a cavity; the sliding wheel assembly is arranged on at least one of the first stand column and the second stand column, and the sliding wheel assembly is used for conducting axial guiding and radial limiting on sliding of the second stand column; the fixed end of the gas spring is fixed in the containing cavity, and the movable end of the gas spring extends into the cavity and is fixedly connected with the second stand column; the supporting table is fixed to the end, away from the base, of the second stand column. The lifting control assembly is arranged on the supporting table and used for controlling the movable end of the air spring to stretch out and draw back. The lifting function of the trolley is directly achieved through the combination of the sliding wheel assemblies and the gas springs, the number of parts is greatly reduced, cost is low, meanwhile, the installation steps and the installation technology are simpler, and therefore the requirements of users are met.
本发明提供了一种升降台车,包括底座;第一立柱,固定于底座,第一立柱具有容纳腔;第二立柱,至少部分位于容纳腔内且沿第一立柱的轴向方向滑动装配于第一立柱,第二立柱具有空腔;滑动轮组件,设置于第一立柱和第二立柱中的至少一者,滑动轮组件用于对第二立柱的滑动进行轴向导向和径向限位;气弹簧,气弹簧的固定端固定于容纳腔内,活动端伸入空腔内并与第二立柱固定连接;支撑台,固定于第二立柱远离底座的一端;升降控制组件,设置于支撑台并用于控制气弹簧的活动端伸缩。通过滑动轮组件和气弹簧的组合直接实现台车的升降功能,极大地减少了零部件的数量,成本较低,同时使安装步骤和安装工艺更加简单,从而满足用户需求。
