Abstract

The invention discloses a movable lifting suspension lug mounting device. The device comprises a tray coaming plate, a tray bottom plate, a screw rod, a casing pipe, backing plates, a handle, ferrules, a force application rod, movable pulleys with brakes and a fixed pulley; a non-thread portion of the upper end of the screw rod is welded to the tray bottom plate, and the lower end of the screw rodis inserted into the casing pipe through a nut to achieve vertical ascending and descending; the handle is welded to the backing plates through second knee plates, and the whole device can be moved by pushing the handle; the ferrules are welded to the lower portion of the tray bottom plate, the force application rod is inserted into the ferrules, and therefore a whole tray is lifted and lowered by rotating the screw rod. By means of the movable lifting suspension lug mounting device, suspension lugs are transferred and mounted, the labor cost is reduced, the operation difficulty is small, andassembly positioning is more accurate.

Description

technical field [0001] The invention relates to the technical field of large ships and marine engineering, in particular to a movable lifting lug installation device. Background technique [0002] It is impossible for a ship to be built as a whole from the start of construction to the launch. We will divide the entire hull into several areas, and each area will be divided into several sections for construction. Finally, it will be hoisted and welded. A certain amount of lifting lugs will be required for the section hoisting , to realize segmental turning and carrying operations, the lifting lugs on the reverse side of the hull structure segmented tire frame need to be welded on the back of the upper tire plate, the number is large and the weight is heavy, and it has always been moved to the designated position and installed by manpower, which cost a lot of money manpower, materials, money. [0003] In order to improve the turnover rate of the segmented tire frame and ensure...
