Abstract
The utility model discloses a special lifting appliance for hoisting large tower equipment by a side shifting method; the special lifting appliance is suitable for in-position hoisting construction of larger tower equipment which is less than 1200t in weight, less than 90m in total height of the equipment tower and is provided with main hoisting lugs at the position of 1/3-2/5 of the total height of the equipment. The special lifting appliance for hoisting large tower equipment comprises two hoisting plates, wherein each hoisting plate is formed by welding a hoisting hole plate, an inclined plate and an upper plate; the upper plate is positioned above the hoisting hole plate; the upper plate is connected with the hoisting hole plate through the inclined plate; a hoisting hole is arranged on the hoisting hole plate; a beam is connected between the two upper plates by bolts; a shaft is arranged between the two upper plates above the beam; the shaft is arranged on the two upper plates; two pulley wheels are arranged on the shaft; two wire ropes without rope heads are respectively arranged on two pulleys; a support beam is arranged on the wire ropes without rope heads between the two pulleys by bolts; and the wire ropes without rope heads are hung on a hook. By using the special lifting appliance for hoisting equipment by the side shifting method, the construction cost can be saved, and the construction efficiency can be improved.
Description
Technical field
The utility model be applicable to weight 1200 t with interior, equipment tower body bottom-to-top-height below 90 m; The height of main hanger is specifically related to lateral deviation method hoisting large-size tower kind equipment special hanger about the lifting construction in place of the Large Towers kind equipment at 1/3～2/5 place of equipment bottom-to-top-height.
Background technology
Main equipments such as methanol wash tower are Large Towers kind equipments more common in Coal Chemical Industry and the petrochemical complex construction project, and the common feature of this kind equipment is the setting of its equipment master hanger, and is very near apart from the equipment center of gravity; Hanger often has long distance apart from the equipment top; Usually adopt the center lift-on/lift-off system in the past, carried out hoisted in position, and just must use thick heaviness and very long rope rig; Thereby cause difficulty of construction to strengthen, executive cost increases.
Summary of the invention
The utility model provides lateral deviation method hoisting large-size tower kind equipment special hanger, its objective is in order to practice thrift construction cost, improves operating efficiency.
The utility model comprises two boatswain chairs, and each boatswain chair is made up of lifting hole(eyelet) plate, swash plate, upper plate welding, and upper plate is positioned at the top of lifting hole(eyelet) plate; Upper plate is connected through swash plate with the lifting hole(eyelet) plate; Through bolted connection crossbeam is arranged between two upper plates, be provided with axle between two upper plates of crossbeam top, axle mounting is on two upper plates; Axle is provided with two pulleys; Two no fag end steel ropes are separately positioned on two pulleys, through bolt support beam are installed on the no fag end steel rope between two pulleys, and no fag end steel rope hangs on the suspension hook.
Described lifting hole(eyelet) plate is provided with lifting hole(eyelet).
Described boatswain chair is provided with the reinforcement gusset.
Different with traditional center method lifting construction technology, utilize the utility model can adopt eccentric lift method, when equipment lifting behind predetermined altitude; The rectification of rectifying a deviation again utilizes the system balancing principle to make equipment be in vertical floating state, after carrying out equipment and basic centering and azimuth centering; Main suspension hook slowly lands, and equipment is in place, accomplishes lifting; Practice thrift construction cost, improved operating efficiency.
The method of application of the utility model is: for the ease of in suspender position in place, utilize the hauling rope traction tower body of bottom to arrive the upright position, tower body vertically is seated on the tower body basis, upper plate temporarily is connected for loosening with the tie bolt of axle.
1) two no fag end steel ropes is hung on two gib heads of hoisting crane anchor formula suspension hook, slowly promotes suspension hook, the utility model is placed the top of being hung the equipment hanger;
2) the lifting hole(eyelet) sleeve-board is gone into to be hung in the equipment hanger, promote suspension hook the tubular axis that is hung the equipment hanger is fallen in the following hole of lifting hole(eyelet) plate, and reliably connect;
3) tie bolt of all connecting portions of the utility model is all tightened;
4) in the space of being hung between equipment and the strut bar, fill hard sleeper and billet, and carry out colligation with the 8# iron wire and fix;
5) get into formal lifting program, along with the progressively lifting of being hung the equipment tower body, hung the equipment tower body and begin slippage, when the center of gravity of being hung equipment during near the plumb bob vertical of suspension hook, slipping end, quilt is hung the equipment tower body and is in the nature floating state thereupon;
6) apply level correction tractive force at the afterbody that is hung the equipment tower body; Make by the equipment tower body of hanging progressively to be in the state of standing vertically, when being hung after equipment skirt and basis align, suspension hook slowly lands; To be placed on the basis by the equipment of hanging, the suspension hook of this moment is still keeping 10～30% load;
7) will be hung equipment centering in place and after reliable the connection; The landing suspension hook; After relaxing appears in steel rope, stop hook, the minor crane of coordinating operation will be filled steel plate and sleeper earlier and removed, and the workmen unclamps the tie bolt of the utility model then; The lifting hole(eyelet) plate is taken out from hanging the equipment hanger, by the main heavy-duty machine of slinging the utility model is placed on the ground again.
