Movable double-rope hoisting device for hoisting prefabricated combined pipeline

The utility model discloses a movable double-rope hoisting device for hoisting a prefabricated combined pipeline. The hoisting mechanism comprises a hoisting mechanism body, a connecting block is installed on the outer side of the hoisting mechanism body, a connecting hook is fixed to the bottom of the connecting block, a hoisting sleeve is connected to the outer side of the connecting hook, auxiliary fixing mechanisms are installed on the two sides of the hoisting sleeve, and a hoisting rope is connected to the bottom of the hoisting sleeve; by pressing one side of the movable pad, the firstfastening sleeve and the second fastening sleeve can clamp the outer wall of the prefabricated combined pipeline body, and the effect that it is guaranteed that the prefabricated combined pipeline body is fixed stably and does not loosen is achieved; through the arrangement of the closing mechanism, after an operator arranges the hoisting sleeve on the outer side of the connecting hook, the connecting hook and the connect
