The preparation method of passing through the person in charge in the step described in the utility model (3) mutually is: each is passed through to be responsible for mutually be regarded as whole, indicate before the processing that each passes through the person in charge's open position mutually, cut open after to be processed.
Because single barrel mast complex structure, constitute barrel mast the elongated person in charge, to pass through the person in charge mutually all be the bending steel pipe, intersect each other between the bending steel pipe, so the division of lifting segmentation is most important to the installation at the processing and fabricating of factory and scene.So follow following principle when cutting apart the lifting segmentation.
1, the bidirectional crossed elongated person in charge, for carrying out segmentation, that breaks off that other direction links to each other runs through persons in charge, directly supports and diagonal brace with the person in charge of one of them direction; Because after the elongated person in charge in the barrel mast forwards the back side to from the front; Its direction changes over crossing condition; Installation for the ease of the scene; Seen from the positive facade of barrel mast, the elongated person in charge that must guarantee inside and outside two faces with run through be responsible for consistent, the promptly positive elongated person in charge with run through be responsible for the elongated person in charge at the back side with to run through the person in charge symmetrical about the barrel mast center line.
Avoid the less position of bend radius when 2, elongated person in charge's segmentation is divided, sectionalizing joint is placed the bigger position of bend radius; Because of being made as greatly, the less position of person in charge's bend radius scoops out; Be easy to directly influence the quality of on-the-spot big joint butt joint because of mismachining tolerance; Avoiding the less zone of rear curved radius then can adopt the technology of medium frequency bending of pipe to process in factory; Guarantee its bend radius and appearance and size, thereby guarantee the quality of total.
3, according to the crane capacity of on-site hoisting machinery, each segmentation weight that barrel mast is divided is all at the scene within the crane capacity of lifting machine.
Occupy mentioned above principle, be as the criterion with a direction among the bidirectional crossed elongated person in charge when lifting segmentation is divided, the parallel division, after the division, divides intersegmentally be that the elongated person in charge is passed through persons in charge mutually with other, directly supportted, the welding between diagonal brace, help the lifting at scene;
Reasonably assemble method and assembling sequence can in time be repaired tolerance or cumulative limit that each component processing causes in the preparation method in the utility model; Thereby guarantee the total quality of structure; Therefore, adopt which kind of assemble method and assembling sequence particularly important to the quality of engineering.
The lifting segmentation of barrel mast also confirmed the elongated person in charge and passed through the person in charge mutually after dividing, no matter but be the elongated person in charge or pass through the person in charge mutually; All there is bend radius in its single steel pipe; Be the spatial warping shape,, adopt following method to process for the ease of processing these bending steel pipes.
The elongated person in charge after dividing for segmentation because banjo fixing butt jointing considers to be arranged at the big zone of bend radius, is convenient to the quality of field joint; Guarantee directly then during factory process that the processing of single steel pipe gets final product in the segmentation; The steel pipe of this kind form is adding man-hour, according to the quantity of self bend radius, its two or three bend radius is made as a processing sections processes respectively; Then dock shaping, also should follow when subsection is divided and avoid in the minimum zone of bend radius.
For passing through the person in charge mutually, this passes through mutually to be responsible for and is respectively the single short distortion steel pipe that has the intersection otch, as adopts single processing separately; Can't carry out the processing of bend radius because of its length than weak point, be difficult to guarantee its appearance and size, therefore; This part steel pipe adds the processing of man-hour with reference to the elongated person in charge in the segmentation, with a plurality of pass through mutually to be responsible for be regarded as whole, indicate the open position of each segmentation before the processing; Back cutting intersection otch to be processed; So both solved the difficult problem that single steel pipe can't be processed, also guaranteed simultaneously with elongated steel pipe pass through quality mutually, the more important thing is to pass through mutually to be responsible for to be connected afterwards with elongated steel pipe that its whole line style is guaranteed.
The time to adopt a face in the inside and outside curved surface in assembling be that benchmark carries out integral body and crouches and make to barrel mast in the utility model, and each bending steel pipe location is convenient, and the interior support of interior positive camber helps the control of total quality perpendicular to the earth.
The quality of the fabricating quality of the described barrel mast of the utility model directly embodies at two side direction arc-shaped curved surfaces, because this part bend radius is minimum; Have deviation then directly to influence the type quality of barrel mast slightly, and the bending curvature on inside and outside two curved surfaces is relatively large, makes also adjustment easily of error; So barrel mast at first carries out the location of moulding bed face curved surface steel pipe when assembling; Then locate arc-shaped transition place, both sides, carry out the location of support between interior outside subsequently, carry out the location of another curved surface at last.
The barrel mast end opening is connected with buried column in the utility model, and each person in charge, diagonal brace etc. are the intersection otch, in order to guarantee the quality of connection with buried column, sets up the frock steel pipe with the buried column same size during making, passes through kerf quality mutually with what this guaranteed the barrel mast end opening.
The principle of passing through the person in charge after all should the first elongated person in charge during each curved surface steel pipe location is mutually carried out, and guarantees the elongated person in charge's line style, guarantees integrally-built line style with this.Each bending steel pipe certainly exists the tolerance of processing; Influence assembling quality in when assembling because of each tolerance stack, thus when moulding bed face steel pipe, at first to guarantee with the location of two N-Side surf steel pipe interfaces accurate, strict its theoretical alignment quality of control during two N-Side surf steel pipes in the location; As locating because of the machining tolerance influence; Then should follow after guaranteeing two N-Side surf steel pipes, internal outerplanar steel pipe is done some and is trimmed to principle, because of interior positive camber more slow relatively; Such finishing is handled easily, and does not influence the monnolithic case and the quality of barrel mast.
Barrel mast part Guan Guanxiang passes through in the utility model, and the welding job amount is big, and reasonably the prevention and the finishing of welding sequence and distortion are the key points in the work progress.Barrel mast causes distortion easily because of the welding factor, thereby influences its structure and shape and divide intersegmental quality of connection, in order effectively to control it to effect on structure; The barrel mast overall package is the one side of control; After the assembling factory's inside weld that welds easily under the assembled state is being welded in advance in addition, then each segmentation partition is being stood up the welding of the surplus weld seam in laggard Xingqi, need suitably add support before standing up; Cause subsection deformation in case stand up; After the welding each segmentation is hung on the assembling moulding bed again and carry out integral body and close up, detect intersegmental butt joint quality of each minute, guarantee the total quality of barrel mast with this.
Beneficial effect: the utlity model has following advantage:
1, adopts the design of straight support and diagonal brace in the utility model, when having guaranteed the barrel mast bearing capacity, simplified the structure of barrel mast to greatest extent, practiced thrift raw material;
2, the utility model adopts segmentation to be welded, and the method for on-the-spot overall package has solved the problem that batch production is produced, and has accelerated the progress of making greatly, has shortened the duration, and simultaneously rational segment design has reduced the difficulty and the workload of welding;
3, adopt many in the utility model and pass through the method for being responsible for the combination making mutually, solved the difficult problem that single steel pipe can't be processed greatly because of torsion resistance, linear precision and quality after whole simultaneously the connection;
4, whole reasonably assembling sequence and welding sequence in the utility model, the quality of the barrel mast that has further guaranteed to produce.
