Problems solved by technology
Since the beam of the A-type gantry is a square box, there are machined guide rails around it, and the corners of the guide rails are sharp. If nylon slings are used directly, the force will change suddenly during the turning process of the A-type gantry, and the sharp edges of the beam guide rails may cut off the nylon slings. Bring uncontrollable safety hazards to the turning and hoisting process

The invention relates to the technical field of portal frame hoisting, and discloses an A-shaped portal frame protection device and a mounting method thereof. The A-type portal frame protection devicecomprises a plurality of protection corner structures, a locking assembly and a hoisting belt, wherein the plurality of protection corner structures wrap guide rails at corners of a cross beam of theA-shaped portal frame; the locking assembly is arranged on the outer sides of the plurality of protection corner structures so as to fix the plurality of protection corner structures on the cross beam of the A-shaped door frame; and the hoisting belt is arranged on the cross beam of the A-shaped portal frame in a sleeved mode and wraps the outer sides of the plurality of protection corner structures. According to the A-shaped portal frame protection device, the plurality of protection corner structures wrap the guide rails at the corners of the cross beam of the A-shaped portal frame, sharp edges of the guide rails are prevented from cutting off the hoisting belt in the turnover hoisting process of the A-shaped portal frame, so that the safety of turnover hoisting of the A-shaped portal frame is improved. According to the mounting method, the A-shaped portal frame protection device can be installed on the cross beam of the A-shaped portal frame, mounting is convenient, and the turnover hoisting of the A-shaped portal frame is facilitated.
Description
technical field [0001] The invention relates to the technical field of door frame hoisting, in particular to an A-type door frame protection device and an installation method thereof. Background technique [0002] The stern of some special ships is usually equipped with an A-type gantry for hoisting cargo. Usually the A-type gantry is in a flat state when it arrives. When the A-type gantry needs to be installed, the A-type gantry needs to be turned over by 90°. Present method is to adopt nylon sling and shackle to bind and lock the A-type gantry crossbeam usually to turn over and hoist. Since the beam of the A-type gantry is a square box, there are machined guide rails around it, and the corners of the guide rails are sharp. If nylon slings are used directly, the force will change suddenly during the turning process of the A-type gantry, and the sharp edges of the beam guide rails may cut off the nylon slings. Bring uncontrollable potential safety hazards to the lifting pr...
