Description
Technical field
The present invention relates to a kind of hanging method, particularly relate to a kind of hanging method of Large Towers kind equipment.
Background technology
The Large Towers kind equipment is one of major equipment of land terminal, and like regenerating column, desulfurizer, scrubbing tower, deethanizer, the outstanding feature of these equipment is that body of the tower is uprightly tall and big, wall thin, body of the tower intensity is low, needs field fabrication and on-site hoisting in place.Because the particularity of these Large Towers kind equipments, accurate, safe Hoisting Program is a design-calculated difficult problem.
At present, the hanging method commonly used of Large Towers kind equipment is, makes the auxiliary reinforced frame of lifting body of the tower is strengthened, and adopts 4 groups of anchor ears to hold body of the tower tightly simultaneously, anchor ear is connected with the lifting reinforced frame fixes, and the suspension centre of top of tower is located on the framework and lifts.The method can solve the problem that body of the tower does not have hanger, simultaneously body of the tower is strengthened, and avoids body of the tower in the lifting process, to be out of shape.For preventing, weld safety stop on two groups of anchor ear top bodies of the tower therein because of the friction force between anchor ear and the body of the tower causes the lifting security risk inadequately.Every group of anchor ear position 16 backstops of weldering are guaranteed accident not occur in the lifting as safety control.Concrete lifting step is: one) on the reinforced frame of deethanizer, establish suspension ring, these suspension ring are positioned at the top of deethanizer, on the base of deethanizer, establish another suspension ring, from two suspension ring the deethanizer level are sling respectively with two loop wheel machines; Two) with top suspension ring bonded assembly loop wheel machine with the pull-up of cat head end, finally make tower be in vertical state, with deethanizer lifting to the desired location.Above-mentioned reinforced frame is manufactured complicacy, the time-consuming material that takes, and hoisting is complicated, and very difficulty is installed.
Summary of the invention
The present invention provides a kind of hanging method of Large Towers kind equipment for solving the technical matters that exists in the known technology, and this method easy construction can the reduction of erection time, practices thrift cost.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is: a kind of hanging method of Large Towers kind equipment may further comprise the steps:
One) two of welding connect shackle plate and a bottom lifting shackle plate on plant bottom case, and two connect the both sides that the shackle plate branch is located at plant bottom case, and lifting shackle plate in bottom connects between the shackle plate at two; The fixing pipe collar lifting structure at the top of equipment; Pipe collar lifting structure comprises the pipe collar that is fastened on the equipment tower tube; Pipe collar is connected with two top lifting shackle plates through ring flat-plate; Two tops lifting shackle plate branches are located at the both sides of equipment tower tube, and parallel with the line of centers of equipment tower tube, and respectively with two to be connected shackle plate relative; The top of two top lifting shackle plates is equipped with lifting hole(eyelet); Between relative connection shackle plate and top lifting shackle plate, be provided with tense wire rope, tense wire rope is parallel with the line of centers of equipment tower tube;
Two) first loop wheel machine with the lifting hole(eyelet) of two tops lifting shackle plates as suspension centre, the lifting appliance top; Second loop wheel machine with the lifting hole(eyelet) on the bottom lifting shackle plate as suspension centre, the lifting appliance bottom, two loop wheel machines are sling equipment level;
Three) first loop wheel machine finally makes equipment be in vertical state the pull-up of equipment top, and second loop wheel machine breaks off relations;
Four) first loop wheel machine with equipment hoisting to the desired location.
Said pipe collar comprises two up and down, and two pipe collars respectively are connected with two top lifting shackle plates through a ring flat-plate up and down.
Said top lifting shackle plate adopts from middle half I-beam section that blocks of web, and a part is respectively clipped in the web top and the bottom of half I-beam section, makes the remainder web as the lacing wire between two ring flat-plates, inboard and two the pipe collar welding up and down of remainder web.
Advantage and good effect that the present invention has are: 1) the suspension centre pattern is simple, is convenient to the field worker assembly and disassembly, has reduced the risk of workman's aloft work; 2) do not relate to the problem of anchor ear squeese pressure, therefore safer; 3) the auxiliary materials of lifting have reduced by 78% than traditional handicraft, greatly reduce hoisting cost; 4) can select suitable position that suspension centre is installed according to the intensity of tower kind equipment self, can damage equipment.
In sum; The top that the present invention is employed in equipment is collar-shaped lifting structure fixedly; And collar-shaped is lifted by crane structure to the employing steel rope and plant bottom case links together, and during lifting, passes to the higher plant bottom case of structural strength to the payload segment that is born on the more weak relatively tower tube of intensity; Thereby more reasonably distributed load has made full use of the structure bulk strength; Under the situation of not using large-scale holding clamp, large-scale crane, fully use the camp site limited resources, with two crane lifting Large Towers kind equipments; With respect to other lifting modes, the lifting holding clamp is simple in structure, and lifting construction is easy; Duration is short, convenient disassembly, and cost is low.With respect to the anchor ear hoisting, the present invention has reduced aloft work, has reduced construction risk.In a word, the present invention is safer, efficient, operation is easier, and has practiced thrift the auxiliary materials of lifting and prefabricated time and expense, has better economic property and practicality.
