FIG. 2 is a schematic diagram of an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.
As shown in fig. 1-2, the present embodiment discloses a device for centering and fixing a pipe, which comprises two parts, namely a clamp and a kit. The clamp comprises an adjusting lug plate, a clamp frame and a clamp fixing bolt. Two sections of short pipes and straight ruler of the matching tool.
Go up to set up two regulation otic placodes on the clamp, two regulation otic placodes are in on two trisection points of clamp frame respectively, and adjust otic placode and clamp frame and fix by the electric welding, adjust the otic placode and be in the position placed in the middle on clamp frame width direction, adjust the otic placode body narrow strip section and need to grow out about clamp frame 50 mm. The straight plates at the left side and the right side of the upper clamping hoop frame are respectively provided with a light hole, and the light holes are positioned at the central positions of the straight plates at the left side and the right side of the upper clamping hoop. The clamp body is made by cold bending a strip plate, and can be formed by cold bending processing by selecting different dies according to different pipe diameters.
The upper clamping hoop frame and the lower clamping hoop frame of the lower clamping hoop are of the same type, the upper clamping hoop frame and the lower clamping hoop frame can be used interchangeably, the adjusting ear plates are of the same type and can be used interchangeably, but the installation directions of the adjusting ear plates are different, so that the upper clamping hoop and the lower clamping hoop are in a mirror image relationship and are not the same object.
The fixing bolt is divided into a bolt and a nut which are matched with each other and are matched with the unthreaded holes on the straight plates on the left side and the right side of the upper and lower clamping hoop frames, and the upper and the lower clamping hoops and the pipe are fixed through the unthreaded holes on the straight plates on the left side and the right side of the upper and the lower clamping hoop frames.
The narrow section of the adjusting lug plate body needs to be lengthened by about 50mm out of the upper clamp frame, sufficient space for subsequent welding seam electric welding is guaranteed, the end part of the narrow section of the adjusting lug plate is provided with a nut, the nut and the narrow section of the adjusting lug plate are fixed through electric welding, the plane of the nut and the plane of the narrow section are in the same horizontal plane, the nut needs to be provided with a bolt matched with the model of the nut, the length of the bolt needs to be guaranteed to be completely screwed into the nut and then lengthened by about 20mm out of the clamp frame, and pipes can be fully fixed.
The adjusting lug plate, the clamping hoop frame and the clamping hoop fixing bolt are all made of stainless steel materials.
The upper clamping hoop and the lower clamping hoop are fixed on a first section of pipe through fixing bolts, when the upper clamping hoop and the second section of pipe are centered, the upper clamping hoop and the lower clamping hoop are adjusted through adjusting the narrow strip section nuts of the lug plates to adjust the narrow strip section nuts, the upper clamping hoop and the lower clamping hoop are provided with four adjusting lug plates, the four adjusting lug plates are located at four quartering points of a 360-degree circular arc, the two sections of pipes are in butt joint, dislocation occurs in any direction, and the adjustment can be performed through adjusting the corresponding adjusting lug plate narrow strip section nuts to match the bolts.
After the centering is finished, the straight ruler is used for extending the direction of the central line of the pipe and leaning against the outer wall of the pipe, and whether the pipe is centered to meet the standard requirement is checked. After the pipes are tested to be qualified in centering, the four adjusting lug plates fix the two sections of pipes in four directions, so that welding seam electric welding operation can be directly carried out, after the electric welding is finished, the four adjusting lug plate narrow strip section nuts are loosened, the fixing bolts are loosened, and the operation is finished. The invention can be repeatedly used, and saves cost.
