The top rotating mechanism comprises rotating box, skirt backplanes support cambered plate, skirt housings support plate, positioning of rotating plate; Rotating box captive joint skirt backplanes support cambered plate; Skirt backplanes support cambered plate connects skirt housings support plate, and rotating box cambered surface both sides are provided with the positioning of rotating plate.
Rotating box is established a calibrated disc on one side, and calibrated disc is provided with pointer.
The present invention slips the tail method and comprises the following steps:
(1) rotation tail row installs: with crane two tails row lower support base is positioned over slide tail erect-position place respectively; The welding of lower support base is fixed on the pre-buried earth anchor on ground; Tail row connecting rod is installed; The flange that connects lower support base and connecting rod by stud; Make two tails row base for supporting become as a whole,, increase lubricated at lower support base surfaces of revolution coating butter; Face is put into respectively on the lower support base about then two top rotating box being distinguished, and tail row is installation;
(2) equipment dress row: a crane stands in the equipment afterbody; Suspension hook connects dress row hanger; Main crane stands in main lifting erect-position position; Connect main hanger; After the lifting rigging connect to be accomplished and inspection confirms, two cranes were coordinated to hoist equipment is lifted away from the transportation saddle, adjusts under top rotating box that two crane armed lever positions make tail row is positioned at bottom the skirt; Two cranes of coordinated manipulation fall on the rotating box of tail row top equipment after rise, accomplish the dress row work of equipment;
(3) slide tail process: the joint inspection before lifting after all lifting preparations are accomplished; Try lifting after confirming to reach the lifting condition; Main crane is stressed; The equipment head is lifted the back time-out to hoist; Once more main crane and rotation tail heat-extraction system are carried out joint inspection; After confirming no abnormal situation; Accomplishing examination hangs; Formally lift, remove in the commentaries on classics method hoisting process, give more sustained attention rotation tail row rotation mated condition; Gradually equipment is erected; When equipment and hoist lifting hook were in the nature erectility, when promptly tail row pointed 90 was spent, the tail work of slipping was promptly accomplished;
(4) rotation tail row dismounting:, respectively two top rotating box are lifted on the disassembled for transport car with a crane; Unclamp, unload bolt, pull down pipe link, and lift on the disassembled for transport car; With gas cutting two lower support bases and the cutting of earth anchor connecting portion are separated from, and lift on the disassembled for transport car.
The present invention is through slipping tail tail row and carried out comprehensive improvement existing, has simple in structurely, easy to make, economic and practical, and good stability not be used on the equipment barrel advantages such as welding hanger.Not enough to on-the-spot crane resources, under the unallowed situation of on-the-spot site condition, or, all can adopt the present invention from practicing thrift cost consideration.
