Background technology
At present, in pipeline construction process, when butt welding of pipelines, mainly contain lifting machine and coordinate and manually regulate and the equipment of suiting one's training regulates two kinds of modes.For the method for artificial adjustment counterpart, efficiency is very low, and human factor impact is large, and concentricity is difficult to accurate control.Device for aligning pipeline is a kind of counterpart and weld seam adjusting device that is applied to the steel-pipe welding such as feedwater piping, sewage pressure pipe.It has two kinds of functions simultaneously: the one, in pipeline engineering construction, adjust the required weld gap of welding, and the 2nd, can Quick aligning welded pipe line.The all kinds device for aligning pipeline occurring in the market, has no extensive use, and main cause is utensil heaviness, and efficiency is low, operates loaded down with trivial detailsly, and the scope of application is narrow, and price is comparatively expensive.When engineering construction, traditional construction appliance is subject to space constraints not easy to operate, the technical problem that exists counterpart difficulty, weld seam adjustment difficulty etc. to be difficult to overcome when concrete operation.
Therefore, be necessary to research and develop a kind of simple to operate, efficiency is high, the plumbing steel-pipe welding contra-aperture device of concentricity accurate positioning, to meet the demand of middle-size and small-size pipeline butt construction.
Utility model content
The purpose of this utility model is to overcome the above-mentioned defect of mentioning and deficiency, and a kind of plumbing steel-pipe welding contra-aperture device is provided, simple to operate, efficiency is high, concentricity accurate positioning.
The technical scheme that the utility model is realized its object employing is as follows.
Plumbing steel-pipe welding contra-aperture device, comprise two groups of same axle center and spaced locating ring, every group of locating ring is made up of two Semicircular counterpart ring plates, described counterpart ring plate both sides are provided with chucking lug, are equipped with the high strength bolt connection pairs in order to fixing upper and lower two counterpart ring plates on adjacent chucking lug.
Plumbing steel-pipe welding contra-aperture device, also comprises jack-post, and described counterpart ring plate inner side is evenly laid with the groove of circular arc, and the axial line of described jack-post and locating ring is parallel to each other and is embedded at corresponding groove on two groups of locating rings.
The groove of all establishing in every counterpart ring plate has 3, and the degree of depth of described groove is less than 1/3rd of jack-post.
The junction of described chucking lug and counterpart ring plate is provided with ribs.
Described ribs has 3 roads.
Between adjacent chucking lug, be folded with anchor plate.
The width of described counterpart ring plate is not less than 5cm.
Plumbing steel-pipe welding contra-aperture device, simple in structure, intensity is high, rigidity is large and good stability, lightweight, it is convenient to install, and carry and hoist is convenient, has saved a large amount of artificial and turnover expenses, and has installed simply, and the rear dismounting of having constructed is safe, convenient.This device can complete weld seam adjustment and two functions of pipeline butt simultaneously, and time saving and energy saving, security performance is high, simple to operate.Maintenance of equipment cost is lower, does not need special corrective maintenance, is specially adapted to pipeline and arranges concentrated and the relatively little occasion in space, and the counterpart of waney two by-pass lines is suitable for too.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Plumbing steel-pipe welding contra-aperture device, comprises two groups of same axle center and spaced locating ring 1, is set in respectively pipeline stiff end and pipe movable end docks in order to pipeline.Described locating ring 1 is made up of two Semicircular counterpart ring plate 1a.Upper and lower two counterpart ring plate 1a close up, and form the space of accommodating pipeline.Described counterpart ring plate 1a both sides are provided with chucking lug 5, are connected and fixed the corresponding chucking lug 5 of upper and lower counterpart ring plate 1a with high strength bolt connection pairs 4.
As preferably, described chucking lug 5 is equidistantly provided with 3 road ribs 3 with the junction of counterpart ring plate 1a.Described chucking lug 5 comprises two-layer, and one deck is body layer, and another layer is enhancement Layer.Body layer is to bend and form with counterpart ring plate 1a one, and enhancement Layer is one steel plate being welded with in body layer, in order to strengthen the intensity of chucking lug 5.
Described counterpart ring plate 1a adopts the steel plate of 5mm to bend and forms, and the width of counterpart ring plate 1a is not less than 5cm.The arc length of monolithic counterpart ring plate 1a is about 3/4 of pipeline semicircle arc length.
As preferably, described counterpart ring plate 1a inner side is evenly laid with the groove 1a1 of 3 road circular arcs, on described groove 1a1, is embedded with jack-post 2, and the radian of the radian of groove 1a1 and jack-post 2 matches.Described jack-post 2 is parallel to each other with the axial line of locating ring 1 and is embedded at groove 1a1 corresponding on two groups of locating rings 1 simultaneously, in order to guarantee the concentricity of two groups of locating rings 1.Jack-post 2 is between locating ring 1 and pipeline, and locating ring 1 is exerted pressure to pipeline by jack-post 2, thus targeted duct.Directly act on pipeline than locating ring 1, jack-post 2 has applied linear force to pipeline, can adapt to better the shape of pipeline, has reduced the requirement to pipe shape, has increased the adaptability of equipment.
More specifically, the degree of depth of described groove 1a1 is less than 1/3rd of jack-post 2.
As shown in Figure 1,5 adjacent of chucking lugs are folded with anchor plate 6, can be according to the number of plies of the size adjustment anchor plate 6 of pipeline, thus make this equipment be applicable to the pipeline of different-diameter.
The use procedure of this equipment is as follows: in the time that pipeline docks, first a locating ring 1 is sheathed on to the end of a pipeline, the end that again another locating ring 1 is installed on to another root pipeline, installs jack-post 2 and anchor plate 6, determines that jack-post 2 is without bending and vertical with locating ring 1.Two pipelines are coaxial docking, and locating ring 1 gradation is carried out fastening, until all tighten.
In sum, this device structure is simple, easy to use, and to managing fast, applicability is wide, and practicality is good.
The utility model is illustrated according to embodiment, is not departing under the prerequisite of present principles, and this equipment can also be made some distortion and improvement.It should be pointed out that all employings are equal to the technical scheme that the modes such as replacement or equivalent transformation obtain, and all drop in protection domain of the present utility model.
