The invention discloses a liftable roller device, which comprises a frame, a lifting assembly, a traction assembly and a transmission part, and is characterized in that the lifting assembly is rotatably mounted on the frame and is used for realizing the lifting of a roller; the traction assembly is arranged in the frame in a reciprocating motion mode, connected with the lifting assembly and used for driving the lifting assembly to rotate. The transmission part is rotatably installed at one end of the frame, and one end of the transmission part penetrates through the frame to be movably connected with the traction assembly and used for driving the traction assembly to move in a reciprocating mode. The lifting height of the roller is increased in a limited space, the space occupied by the roller device for meeting the lifting requirement is greatly saved, and the roller device has the advantages of being small in occupied space, simple in structure and convenient to operate.
本发明公开了一种可升降的滚轮装置,包括框架、升降组件、牵引组件和传动部件,所述升降组件可转动地安装在所述框架上,用于实现滚轮的升降;所述牵引组件可往复移动地设于所述框架内,与升降组件相连,用于带动升降组件转动;所述传动部件可旋转地安装在框架的一端,所述传动部件的一端穿过框架与牵引组件活动连接,用于带动牵引组件往复移动。本发明在有限的空间内提高了滚轮升降的高度,大大节省了滚轮装置为了满足升降所占用的空间,具有占用空间小、结构简单、方便操作的特点。
