The invention provides a lifting adjusting device and a trolley. The lifting adjusting device comprises a driving unit, a stepping unit, a connecting rod unit and a lifting body which is arranged on a base body and can move in the direction away from/close to the base body. When the lifting body is located at the position close to the base body, the base body is supported by the supporting body. When the lifting body is located at the position away from the base body, the base body is supported by the lifting body. The driving unit comprises a driving part and an output shaft; the stepping unit comprises a lead screw connected to the output shaft and a lead screw driven part; the connecting rod unit is connected with the lead screw driven part and the trundles. When the driving part moves in the driving direction, the driving output shaft drives the lead screw to rotate in the forward direction and pushes the lead screw driven part to translate by the corresponding step length, and the lead screw driven part drives the lifting body to move by the corresponding distance in the direction away from the base body through the connecting rod unit. And when the driving part is reset in the reverse direction, the driving part does not drive the output shaft. Therefore, through alternate supporting of the lifting body and the supporting body, switching of the trolley between the static state and the moving state is achieved.
本申请提供一种升降调节装置及台车,包含驱动单元、步进单元、连杆单元和设置于基体、可朝远离/靠近基体的方向移动的升降体;当升降体位于靠近基体的位置时,基体被支撑体支撑;当升降体位于远离基体的位置时,基体被升降体支撑;驱动单元包含驱动部和输出轴;步进单元包含连接于输出轴的丝杠及丝杠从动部;连杆单元分别与丝杠从动部和脚轮连接;当驱动部沿驱动方向运动时,驱动输出轴带动丝杠正向转动并推动丝杠从动部平移对应的步长,丝杠从动部经由连杆单元带动升降体朝远离基体的方向移动对应的距离;当驱动部反方向复位时,驱动部不驱动输出轴。据此,通过升降体和支撑体交替支撑,实现台车在静止状态和移动状态之间的切换。
