The invention relates to an ejection type lifting device, and solves the problems of complex structure and no lifting function of the existing device. The ejection type lifting device consists of an ejector, a circulating lifter and a magazine type tractor, wherein a motor is fixedly mounted on the circulating lifter; a guide head grabs a fixed object without loosening; a left lifting rope is wound around the rear lower portion of a left friction wheel and then penetrates through the position over a conveying wheel; a right lifting rope is wound around the front upper portion of a right friction wheel and penetrates to the rear lower portion of a rotary wheel; a crank screw on an opening and closing box is rotated; and the friction wheels at the two ends of an extrusion shaft simultaneously press down to respectively press lifting ropes together with a conveying wheel and a rotating wheel at the two ends of a transmission shaft. The motor is started to rotate anticlockwise in the forward direction, the conveying wheel and the left friction wheel rotate and extrude the lifting rope at the left end to move forwards and ascend, and the rotating wheel and the right friction wheel rotate and extrude the lifting rope at the right end to pull back and descend, so that a rope gripper fixed to the lifting rope at the left end synchronously ascends to the needed height.
本发明为弹射式升降装置,解决已有装置结构复杂,没有升降功能的问题,由弹射器,循环升降机,弹仓式牵引器组成。循环升降机上固定安装有电动机,导引头抓住固定物体不松动,将左侧升降绳从摩擦轮后下方绕过再穿过传送轮正上方,将右侧升降绳从摩擦轮前上方绕过穿到回旋轮后下方,旋转开合箱上的曲柄螺杆,挤压轴两端的摩擦轮同时下压分别与传动轴两端的传送轮,回施轮压紧升降绳。启动电动机作逆时针正向转动,传送轮和摩擦轮旋转挤压左端升降绳前送上升,回旋轮和摩擦轮旋转挤压右端升降绳回拉下降,固定在左端升降绳上的夹绳器就实现同步升到需要的高度。
