Lifting mechanism

Abstract

The invention relates to a lifting mechanism. The lifting mechanism comprises a main frame, a wire guide mechanism and pull wires, wherein the main frame comprises an outer frame and a guide bent plate, and the wire guide mechanism comprises propelling oil cylinders, cylinder head movable pulley sets and steering fixed pulley sets; at least two propelling oil cylinders are provided, and the two propelling oil cylinders are oppositely arranged on the guide bent plate, the end of a piston rod of each propelling oil cylinder is connected with the corresponding cylinder head movable pulley set, and sliding assemblies are arranged at the bottoms of the cylinder head movable pulley sets; the steering fixed pulley sets at least comprise the first steering fixed pulley set, the second steering fixed pulley set and the third steering fixed pulley set, the two side edges in the length direction of the outer frame are taken as a first long side edge and a second long side edge, the first steeringfixed pulley set is arranged at one end of the first long side edge, and the second steering fixed pulley set and the third steering fixed pulley set are arranged at the other end of the first long side edge side by side; and the two ends of the first long side edge are each provided with a pull wire penetrating hole, and each pull wire is fixed to one end of the second long side edge and then penetrates out of the corresponding pull wire penetrating hole through the wire guide mechanism. According to the lifting mechanism, multi-point balance lifting can be carried out on a heavy object.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a lifting mechanism. Background technique [0002] Four-point balance lifting has always been a difficult problem in mechanical transmission. The contradiction between the synchronization, stability, size of the transmission mechanism, bearing capacity and safety issues in the four-point lifting device has always made this lever difficult to balance. Thereby it is difficult to meet the demands of various mechanical equipment for the four-point lifting device. [0003] Most of the hoisting mechanisms currently used have complex structures, large volumes, and slow hoisting speeds. During the hoisting process, many problems such as easy detachment of the hoisting steel wire and poor guiding of the propulsion mechanism will occur. Contents of the invention [0004] The present invention is proposed in view of the above problems, and its purpose is to provide a lifting mechanism...
