Step 3 lays 2 channel-section steels as guide rail at the aisle platform on electric panel room doorway, and is laid on guide rail by 4 steel pipes, and mobile crane is in place, and is linked in mobile crane suspension hook by the hook of Chain block and 2 long wire rope;
Step 4 is carried out examination before lifting by crane and is hung, and heavy electrical cabinet maintenance level in hoisting process guaranteed by adjustment Chain block;
By the rope made of hemp, (at heavy electrical cashier's office in a shop, mobile crane formally lifts by crane step 5 in colligation, by the handling of heavy electrical cabinet to the aisle platform on electric panel room doorway;
Step 6 is under the prerequisite ensureing job safety, one end of the rope made of hemp is dragged on the platform of aisle by operating personnel, by the rope made of hemp, heavy electrical cabinet is drawn to Chain block side, the sling height of adjustment mobile crane simultaneously, heavy electrical cabinet is placed on the steel pipe that laid;
Step 7 is under the guiding of crane, relax the chain lock length of Chain block 200mm, slowly lift by crane again, the Chain block 200mm that relaxes first leaves ground by making the long wire rope side of heavy electrical cabinet, when ground 50mm ~ 80mm is left in long wire rope side, drawn heavy electrical cabinet toward layback in the platform of aisle by the rope made of hemp, after mobile crane hoist cable is in vertical position, now continue the chain lock length 200mm of lax Chain block, slowly lift by crane, the rope made of hemp draws heavy electrical cabinet toward layback in the platform of aisle again;
Step 8 relaxes the chain lock length 500mm of Chain block, slowly lift by crane again, when ground 50mm ~ 80mm is left in the side of the long wire rope of heavy electrical cabinet, the rope made of hemp draws heavy electrical cabinet toward layback in the platform of aisle, until whole heavy electrical cabinet is drawn into aisle platform, then 4 suspension ring are removed, then heavy electrical cabinet is pushed electric panel room install; Lift rear recovery and remove guardrail.
The length of described strap is not less than 500mm.The length of described long wire rope is not less than 1m.The length of described strap is 600mm.The length of described long wire rope is 1.2m.
The invention has the beneficial effects as follows: (1) is safe and reliable: compared with routine work method, do not need to set up, remove scaffold lifting operation platform, need operation on scaffold lifting operation platform, avoid the danger that work high above the ground brings, improve the safety of operation; (2) high financial profit: adopt this method can save the turnover trucking expenses that labour cost, cost of materials and the material torn open taken by scaffold; (3) accelerating construction progress: before operation, do not need to spend the plenty of time to carry out the carrying of the materials such as scaffold, the setting up of scaffold lifting operation platform, operation complete after the dismounting of scaffold, improve operating efficiency.
