Abstract
The utility model aims at providing a special machine for assembling and welding an elbow pipe, consisting of a main beam, a supporting leg, a rotary supporting frame, a rotary driving mechanism, a radial and adjustable jack and a top beam, wherein the rotary central line of the rotary driving mechanism is coincided with the circumference central line of the abutting surface of the two elbow pipes; the adjusting quantity of the radial jack is larger than the maximum radial variable of the elbow pipe; and the bevels of the combined parts of the top beam and the elbow pipes are the same. The special machine can realize the mechanical assembly and automatic welding of the two elbow pipes, not only can be used for manufacture in a factory, but also can carry out manufacture or installation of special pipes directly on a steel pipe installation project, and save the transportation expenses of bulk pieces.
Description
Technical field
The utility model belongs to mechanical manufacturing field, has related to a kind of manufacturing or installed device of large-scale steel pipe, and its effect is the assembly welding of large-scale bend pipe.
Technical background
In order to solve large-scale steel pipe manufacturing installation technology problem under certain environmental conditions, the design of large-scale steel pipe mechanization construction technology and steel pipe pallet car is arisen at the historic moment, and it can be finished the scene of large-scale or ultra-large type steel pipe and make installation in the limited space of constructing.Chinese patent 200510020396.7 has proposed automatic manufacturing technique of large sized steel pipe, has simultaneously proposed corresponding mechanism at Chinese patent CN2917917 and CN1803567A and has made the steel pipe manufacturing of level and mechanization is installed and be achieved.Its advantage is to have improved mechanization degree and Automation of Welding level that large-scale steel pipe is made, can reduce simultaneously the difficulty of lifting steel pipes and transportation, reduce production costs, the large-scale steel pipe engineering that is particularly useful for level in tunnel is used, and can obtain stable welding quality and high efficiency production.
In some large-scale steel pipe engineerings, bend pipe is to manufacture the single-unit steel pipe in factory, because structural design needs, the length of bend pipe is shorter, so the relative straight length of the ratio of girth welding is bigger, assembles on common platform and can't weld automatically, aforesaid patented technology can not adapt to the specific (special) requirements that bend pipe is made, and bigger for the bend pipe length overall, the duration be subjected to making and installation influence bigger, traditional method will be difficult to improve engineering efficient.
The utility model content
The purpose of this utility model provides a kind of assembly welding chassis of large-scale bend pipe newly, can be a long tube joint with tile or tube coupling assembly welding directly, makes installation effectiveness and is enhanced about more than once, and engineering cost reduces.
The purpose of this utility model is achieved in that a kind of assembly welding chassis of large-scale bend pipe, described assembly welding chassis by girder, supporting leg, revolution bracing frame, rotary motion mechanism, radially can regulate jack and back timber is formed, the rotation centerline of described rotary motion mechanism overlaps with circle center's line of two bend pipe interfaces, the regulated quantity of described radially jack is greater than bend pipe maximum luffing radially, and described back timber is identical with the knuckle of bend pipe institute binding site.
Compared with prior art, the utility model can be realized the machinery assembling and the welding automatically of two bend pipes, shortened construction period, thereby the production efficiency of bend pipe improves.Its method can be used for the manufacturing in the factory, also can directly carry out shape tube manufacturing or installation in steel pipe installing engineering place, saves big part freight.
Description of drawings
Fig. 1 is a kind of structural plan of bend pipe assembly welding chassis.
The specific embodiment
Embodiment: the bend pipe assembly welding chassis of a large-scale water conveyance steel tube, as shown in Figure 1, carry out the bend pipe assembly welding on the bend pipe assembly welding chassis.Bend pipe assembly welding chassis by girder 11, front leg strut 12, middle supporting leg 13, rear support leg 14, revolution bracing frame 15, rotary motion mechanism 16, radially can regulate jack 17 and back timber 18 is formed, the rotation centerline of rotary motion mechanism 16 overlaps with circle center's line of two bend pipe interfaces, radially the regulated quantity of jack is greater than bend pipe maximum luffing radially, and back timber is identical with the knuckle of bend pipe institute binding site.The tile of bend pipe installs and fixes on the precalculated position of the revolution bracing frame 15 of assembly welding chassis, and the clamping utensil 19 on the usefulness back timber 18 is with tile and assembly welding chassis strong bonded.Tile is after front leg strut 12 outsides enter chassis girder 11 bottoms, front leg strut 12 supports, supporting leg 13 in the contraction, tile arrives the lower end of revolution bracing frame 15, with the fixing tile of the clamping utensil 19 on the back timber 18, drive revolution bracing frame 15, repeat said process, progressively a plurality of tiles are assembled into a single-unit steel pipe, again two single-unit pipe assembly weldings are become a big bend pipe, after welding and having inspected, bend pipe directly installs and fixes, turn round bracing frame at last and shrink, the assembly welding chassis moves axially the length of a big bend pipe joint, carries out the installation of next bend pipe.Because the revolution bracing frame 15 of assembly welding chassis can be along the circumferential weld center rotation of two bend pipe combinations, so all longitudinal joint and circumferential welds of assembly welding stage can weld under general welding equipment cooperates automatically.
It is elementary cell that bend pipe assembly welding chassis can adopt with the tile, on the assembly welding equipment of car-type, form the long tube joint that 2 bend pipes joint is formed, the bend pipe that also available 2 welding are finished is a big bend pipe at the chassis assembly welding, replace traditional large-scale bend pipe single-unit lifting transportation resources, the mechanization degree of making improves, and it is original more than 2 times that the manufacturing of bend pipe and installation efficiency can reach.This technology is applicable to the engineering construction The field, bend pipe can be made nearby at engineering site, and chassis moves, even there is not the problem of traffic condition restriction in big like this tube coupling yet.
Claims (4)
1. one kind large-scale bend pipe assembly welding chassis is characterized in that, the assembly welding chassis by girder, supporting leg, revolution bracing frame, rotary motion mechanism, radially can regulate jack and back timber is formed.
2. large-scale bend pipe assembly welding chassis as claimed in claim 1, the rotation centerline of described rotary motion mechanism overlaps with circle center's line of two bend pipe interfaces.
