The invention relates to a stackable transportation tool. The stackable transportation tool comprises a frame, roller assemblies are arranged at the bottom of the frame, each roller assembly comprisesa mounting seat which is assembled on the frame in a sliding manner, rollers are assembled on the mounting seat, the roller assembly is provided with a walking position and a retracting position, a supporting surface is further arranged on the frame, a locking structure is arranged between the frame and the mounting seat, the locking structure comprises a movable limiting piece and a limiting piece matching part, and the limiting piece is separated from the corresponding limiting piece matching part when the roller assembly is in a switching state so as to unlock the roller assembly. Comparedwith like tools in the prior art, the tool of the invention does not need other independent parts, such as a ground brake, for supporting and fixing, only need to improve the rollers to a certain degree, enables the rollers to be assembled on the frame in a sliding mode and can be kept locked, is low in improvement cost, and solves the technical problem that in the prior art, the cost is high dueto the mode that a ground brake is lowered to lift a conveying material frame.

    本发明涉及一种可叠放的运输工装。一种可叠放的运输工装包括框架,框架底部设有滚轮组件,滚轮组件包括可滑动的装配在框架上的安装座,安装座上装配有滚轮,滚轮组件具有行走位和收回位,框架上还设有支撑面,框架和安装座之间设有锁止结构,锁止结构包括可活动的限位件和限位件配合部,限位件在滚轮组件切换状态时与相应限位件配合部相分离以解除对滚轮组件的锁止。相较于现有技术,本发明不需再设置其他单独的部件,例如地刹器进行支撑固定,仅需对滚轮进行一定改进,将其滑动装配在框架上并能够保持锁止即可,改造成本较低,解决了现有技术中下放地刹器抬起运输料架的方式所存在的成本较高的技术问题。
