Steel structure roof truss hoisting device and using method

Abstract

This invention discloses a steel structure roof truss hoisting device and its usage method, relating to the field of steel structure roof truss technology. It includes a base plate, on which a rotary drive component is mounted. The output end of the rotary drive component is connected to a support column. A diagonal support arm is detachably mounted on the top of the support column. A hydraulic cylinder is mounted on the arm of the diagonal support arm. A multi-stage telescopic arm is rotatably connected to the top of the diagonal support arm, and the arm of the multi-stage telescopic arm is connected to the output end of the hydraulic cylinder. A second multi-stage telescopic arm is mounted outside the first multi-stage telescopic arm, and a connecting plate is fixedly mounted outside the second multi-stage telescopic arm. An adjusting hoisting device is installed under the connecting plate. This invention solves the technical problem that in the construction process of hoisting steel structure roof trusses, cranes are often used for hoisting, which is prone to detachment during actual construction, posing a safety hazard.
