The invention provides a scissor-fork type lifting machine, which belongs to the technical field of lifting equipment, and comprises a scissor-fork body, a horizontal guide rail and a driving device, the scissor-fork body is provided with a first support rod and a second support rod which are in cross rotation connection, and the horizontal guide rail is provided with a first sliding block and a second sliding block; the first sliding block is connected with the scissor fork body through a cam transmission piece. According to the device, the cam transmission part is arranged on the first sliding block, so that the driving device drives the first sliding block to move, the cam transmission part preliminarily lifts the first supporting rod and the second supporting rod in the horizontal state, and then the driving device drives the first sliding block to continue to abut against the second sliding block to move; therefore, the whole scissor fork body can be driven by one set of driving device to ascend or descend.
本发明提供一种剪叉式举升机,属于举升设备技术领域,包括:剪叉本体、水平导轨和驱动装置,剪叉本体具有交叉转动连接的第一支撑杆和第二支撑杆,水平导轨上设置有第一滑动块和第二滑动块,第一滑动块通过凸轮传动件与剪叉本体连接;本发明中,通过在第一滑动块上设置凸轮传动件,使得驱动装置驱动第一滑动块移动,使凸轮传动件将水平状态下的第一支撑杆和第二支撑杆进行初步抬升,再由驱动装置驱动第一滑动块继续抵接第二滑动块移动,即可实现由一套驱动装置驱动整个剪叉本体进行抬升或者降低。
