Abstract

The invention discloses a rotary lifting device, which belongs to the technical field of lifting opening and closing equipment, comprises a lifting appliance, and is characterized in that the lifting appliance comprises an upper lifting frame, a pulley shaft, a movable pulley block, a pin penetrating piece, a lifting head, a lower lifting frame, a lifting hook cross beam, a lifting hook nut, a rotary driving piece and a grabbing beam, the lifting head is fixed on the upper lifting frame through a pin penetrating piece, the lifting hook cross beam penetrates through the lifting hook nut and is arranged on the lower lifting frame, the lifting hook nut is connected with the lifting head, the rotary bearing is arranged between the lifting hook cross beam and the lifting hook nut, the rotary driving piece is arranged on the lower lifting frame, and the grabbing beam is connected with the lower lifting frame. The lifting appliance can synchronously and reversely rotate to ensure that the axis of a gate is always parallel to the axis of a gate groove, and the lifting appliance and the gate are prevented from shaking in the rotation process, so that the gate can be automatically and accurately positioned into the groove, the lifting precision and the lifting efficiency are improved, and the whole rotation lifting appliance is convenient to mount.

Description

technical field [0001] The invention relates to the technical field of lifting, restarting and closing equipment, in particular to a slewing hoisting device. Background technique [0002] Among the existing hoisting equipment, especially the hoisting and closing equipment that uses slewing hoist to hoist objects and needs to be accurately positioned, such as the hoist of a hydropower station to hoist the gate entry slot or entry storehouse. [0003] Since the operation mode of the slewing mechanism is rotary motion, the trajectory and the tangential angle of each door slot or door magazine are different during its operation, so that the axis of the door body cannot be kept with the axis of the door slot and door magazine to be placed during the lifting process. Parallel, even if the wire rope does not swing, it is difficult for the gate to enter the groove without other forces. Therefore, the existing lifting equipment needs manual auxiliary operation to realize the precise...
