Detailed Description

In fig. 1-3, the utility model discloses a spandrel girder 5 that the level set up, connecting plate 2 that the level set up, correction plate 4 of vertical setting, be used for can dismantle the connecting bolt subassembly 3 of connecting the support 11 of waiting to lift by crane work piece 1, spandrel girder 5 middle part has the hole for hoist 51 of being connected with lifting rope 6, and spandrel girder 5 one end is connected with connecting plate 2, and correction plate 4 is connected to the spandrel girder 5 other end, is equipped with regulation hole 21 on the connecting plate 2. The hoisting hole 51 is arranged on the bearing beam 5 and connected with a hoisting tool; the adjusting holes (also called connecting holes) 21 are arranged on the connecting plate 2 and are connected with the workpiece 1 to be hoisted. The correction plate 4 is vertically and tightly matched with the inner side surface of the workpiece 1 to be hoisted, so that the workpiece 1 to be hoisted is always in a vertical state after being hoisted. The connecting plate 2 is connected with the horizontal surface of a support 11 of the workpiece 1 to be hoisted, and the upper surface of the workpiece 1 to be hoisted is ensured to be horizontal. Under the assistance of adjusting hole 21, adjustable correcting plate 4 to with wait to hoist the interval L of 1 medial surface of work piece, when interval L =0mm, correcting plate 4 to with wait to hoist 1 medial surface tight fit, adjusting hole corresponds with the support 11 connecting hole 21 of waiting to hoist the 1 outside of work piece on connecting plate 2 and forms a bolt pilot hole, be used for connecting wait to hoist 1 connecting bolt subassembly 3 of work piece and wear to adorn in bolt pilot hole department, behind the assembly connecting bolt subassembly 3, the centre gripping frock with wait to hoist 1 tight fit of work piece, can lift by crane the operation.
