Description

Technical Field

[0001] The utility model relates to the technical field of pipeline measurement, in particular to a measuring device for a prefabricated pipeline with a flange. Background Art

[0002] With the rapid development of modern construction, prefabricated pipes have been widely used in various construction projects. The installation quality of prefabricated pipes is directly related to the safety and service life of the entire project. However, in actual construction, large errors in the verticality and length measurement of prefabricated pipes often occur. This not only affects the construction progress, but also may lead to safety hazards and waste resources.

[0003] Prefabricated pipe error control is complex and challenging. Traditional methods for measuring verticality and length in prefabricated pipes rely primarily on manual labor, which has numerous drawbacks. These include low measurement accuracy, inefficiency, and significant susceptibility to human error. These issues severely hinder improvements in construction project quality.

[0004] As the instruction manual Figure 1 As shown, a common pipeline is provided with a flange 2 (flange surface) at the end of the pipe body 1, and a flange surface water stop ring 3, which is a circle of raised structure, is provided on the flange 2. The flange 2 is welded to the pipe body 1 and there is a weld 4; a right-angle ruler 5 is used to measure the verticality of the pipe body and the flange, but the presence of the weld makes the measurement inaccurate, and the right-angle ruler of this structure has a large error when verifying the verticality; when measuring the length of the pipeline, a tape measure is usually used to pull a line from the flange for measurement. Due to the presence of the flange surface water stop ring, the size of the flange surface water stop ring will be ignored when the end of the tape measure is overlapped at the edge of the flange for measurement, making the measurement structure inaccurate. If the measurement is overlapped from the inner circumference of the pipeline, although the size of the flange surface water stop ring can be taken into account, for longer pipelines, it is difficult to pull the tape measure from the inside of the pipeline, and the operation is inconvenient. Summary of the Invention

[0009] This measuring device has a good measurement correlation for pipes with bosses (flange surface water stop rings) on the flange surface. It can conveniently and accurately measure the length and judge the verticality with the end face of the flange surface water stop ring as the reference plane. The total length of the pipe obtained in this way is more accurate, and it also overcomes the problem that the end reference plane cannot be accurately positioned and effectively measured using a ruler or tape measure.

The leveling mounting plate is usually arranged parallel to the horizontal support plate; the leveling detection piece can detect the horizontality, assist in the judgment of verticality, and be used in the subsequent determination of the center line of the pipe body.

[0011] Furthermore, the abutting surface of the vertical support plate is a magnetic surface, which facilitates its connection and fixation.

[0012] Furthermore, the magnetic surface is a magnetic strip, a magnetic sheet or a magnetic frame provided on the vertical support plate.

[0013] Furthermore, the level detection component is a spherical level bubble, and the spherical level bubble is arranged in the middle of the level mounting plate. Such an arrangement can facilitate the determination of the center line of the pipeline.

[0014] Furthermore, the vertical connecting plate and the horizontal supporting plate are an integrated L-shaped structure, and the upper end of the vertical connecting plate is connected to the side edge of the horizontal mounting plate.

[0015] Alternatively, the upper end of the vertical connecting plate is further connected to a connecting short plate, and the connecting short plate is connected to the horizontal mounting plate; the connecting short plate, the vertical connecting plate and the horizontal supporting plate are connected into an integral Z-shaped structure.

[0016] Furthermore, the vertical support plate, the vertical connecting plate and the horizontal support plate are arranged in the same plane.

[0017] Furthermore, the spacing is greater than the thickness of the flange edge to ensure that the flange edge can be accommodated between the two. An outer notch is provided at the right-angle transition between the vertical connecting plate and the horizontal support plate to avoid the weld.

[0018] Furthermore, the distance measuring sensor is a laser rangefinder, and a light blocking plate is provided below the leveling mounting plate. One side of the light blocking plate is flush with the abutting surface of the vertical support plate, and the reference end of the distance measuring sensor is arranged against the surface of the light blocking plate.

DETAILED DESCRIPTION

[0028] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0030] like Figure 2 As shown, a measuring device for a prefabricated pipe with a flange includes a vertical support plate 6, on which a leveling mounting plate 7 is provided, and on which a leveling detection part 11 is provided; one side of the leveling mounting plate 7 is connected to a vertical connecting plate 9 parallel to the vertical support plate 6, and a spacing is provided between the vertical connecting plate 9 and the vertical support plate 6 to accommodate the flange edge on the pipe; the end of the vertical connecting plate 9 is provided with a horizontal support plate 10 perpendicular to the vertical support plate 6, and the leveling mounting plate 7 is also provided with a distance sensor 13.

[0031] Through the arrangement of the vertical support plate 6, the horizontal support plate 10 and the distance measuring sensor 13, this measuring device can effectively measure the size of the prefabricated pipe with flange, especially the distance between the flange end faces, that is, the total length of the pipe, and can determine or verify the verticality between the flange end face and the pipe body; it can not only improve the measurement accuracy and efficiency and reduce construction costs, but also effectively reduce safety hazards and improve the overall quality of the construction project.

[0032] This measuring device has a good measurement effect for pipes with a boss on the flange surface (flange surface water stop ring 3). It can conveniently and accurately measure the length and judge the verticality with the end face where the flange surface water stop ring is located as the reference plane. The total length of the pipe obtained in this way is more accurate, and it also overcomes the problem that the end reference plane cannot be accurately positioned and effectively measured using a ruler or tape measure.

[0033] The vertical support plate 6, the leveling mounting plate 7, the vertical connecting plate 9, and the horizontal support plate 10 are connected to form a vertical-horizontal-vertical-horizontal rule structure. The spacing between the vertical support plate 6 and the vertical connecting plate 9 is just enough to accommodate the flange 2, allowing the entire measuring device to be installed on the flange 2 for abutment, adjustment, and measurement. This arrangement is well suited for dimensional inspection of flanged pipes.

[0034] The vertical support plate 6 and the horizontal support plate 10 are arranged perpendicularly at 90 degrees to each other. When the vertical support plate 6 abuts the flange end face (or the flange face water stop ring), the horizontal support plate 10 should be parallel to the pipe body 1. If the perpendicularity between the pipe body 1 and the flange end face is not accurate, this deviation can be visually observed. Products with unqualified perpendicularity require rework and do not require subsequent measurement. Only when the perpendicularity is qualified can length measurement be accurate and meaningful.

[0035] The setting of the leveling mounting plate 7, on the one hand, is to facilitate the connection of the vertical support plate 6 and the vertical connecting plate 9 to form an integrated structure, and on the other hand, it can be used as a mounting component to install the leveling detection member 11 and the distance sensor 13 and other accessories. The leveling mounting plate 7 is usually arranged parallel to the horizontal support plate 10; the leveling detection member 11 can detect the horizontality, assist in the judgment of verticality, and be used in the subsequent determination of the center line of the pipe body.

[0036] Furthermore, the abutment surface of the vertical backrest 6 is a magnetic surface 12. By means of magnetic attraction, the vertical backrest can be easily abutted and adsorbed on the flange end surface, which is not easy to fall or shake. At the same time, it is also convenient for rotation adjustment and disassembly, and will not cause damage to the original structure of the pipeline due to connection and installation.

[0037] Furthermore, the magnetic surface 12 is a magnetic strip, magnetic sheet, or magnetic frame provided on the vertical backrest, or other types of magnetic materials. These magnetic components can be fixed to the vertical backrest by embedding, bonding, or snapping, and the surface of the magnetic flange of these magnetic components is the surface for abutment and connection.

[0038] Furthermore, the level detection member 11 is a spherical level bubble, which is arranged in the middle of the level mounting plate 7. Through the spherical level bubble, it is possible to visually observe whether the level mounting plate is level, and whether the level bubble therein is centered can be judged.

[0039] In some embodiments, a mounting groove is provided in the middle of the level mounting plate, and the spherical level bubble is installed in the mounting groove.

[0040] In some embodiments, the vertical connecting plate 9 and the horizontal support plate 10 are an integrated L-shaped structure, and the upper end of the vertical connecting plate 9 is directly connected to the side edge of the leveling mounting plate 7. The leveling mounting plate can be directly connected through the vertical connecting plate, and the size of the leveling mounting plate will be larger in this case.

[0041] In some embodiments, the upper end of the vertical connecting plate 9 is further connected to a connecting short plate 8, which is connected to the leveling mounting plate 7. The connecting short plate 8, the vertical connecting plate 9, and the horizontal support plate 10 form an integrated Z-shaped structure. This structure, in which the leveling mounting plate is connected by the connecting end plate, can reduce the size of the leveling mounting plate.

[0042] Furthermore, the vertical support plate 6, the vertical connecting plate 9 and the horizontal support plate 10 are arranged in the same plane, which is conducive to accurate measurement.

[0043] The vertical support plate, the vertical connecting plate and the horizontal support plate are all made of steel plate structures, and the side walls in the thickness direction are used as the support surfaces. This makes it more convenient to take these support plates and will not cause misjudgment due to excessive contact surface.

[0044] Furthermore, the spacing is greater than the thickness of the flange edge, and an outer notch 16 is provided at the right-angle transition between the vertical connecting plate 9 and the horizontal supporting plate 10 to provide space so that the horizontal supporting plate can abut against the pipe body.

[0045] For large pipelines, their flanges are usually welded to the end faces of the pipe bodies. There will be a circle of weld seams at the welding point between the pipe body and the flange. The cross section at this position is not a right angle. Therefore, the outer notch 16 is provided at the right angle between the horizontal support plate and the vertical connecting plate, which can effectively avoid the adverse effects of the weld seam.

[0046] Furthermore, the distance sensor 13 is a laser rangefinder, and a light blocking plate 14 is provided below the leveling mounting plate 7 . One side of the light blocking plate 14 is flush with the abutting surface of the vertical support plate 6 , and the reference end of the distance sensor is arranged against this surface of the light blocking plate 14 .

[0047] After the laser emitted by the laser rangefinder is blocked by the light blocking plate on the opposite side, the distance between the two can be measured. Since the light blocking plate is also flush with the flange end face (or the flange surface water stop ring), the distance between a pair of flange end faces can be obtained by adding the reference size of the laser rangefinder itself.

[0048] Furthermore, liftable legs 15 are provided on both sides of the vertical connecting plate below the leveling mounting plate 7 , and rolling elements are provided at the ends of the liftable legs 15 .

[0049] By setting the liftable legs 15 and the rolling elements, the device can be supported on the outer periphery of the flange and can move along the outer periphery of the flange, and the support height can be adjusted according to actual conditions. This setting can not only improve the stability of the installation of the measuring device on the pipeline, but also facilitate the determination of the center line of the pipe body.

[0050] In some embodiments, the liftable leg 15 is an adjustable screw, or an adjustable and lockable telescopic rod, and the rolling element is a ball embedded in the end or a roller installed at the end.

[0051] This measuring device can not only measure straight pipes, but also L-shaped pipes with flanges, T-shaped pipes with flanges, F-shaped pipes and π-shaped pipes. Short pipes, long pipes, thin pipes and thick pipes can all be measured. The following takes a straight pipe as an example, combined with Figures 3 to 6 Explain the measurement process.

[0052] First, measure the verticality of the flange surface water stop ring 3 and the pipe body 1, place the vertical support plate 6 against the end face of the flange surface water stop ring 3, place the horizontal support plate 10 on the pipe body 1, observe whether the horizontal support plate 10 fits the pipe body 1, rotate the vertical support plate 6 within 360 degrees, with each rotation not less than 90 degrees, and test it an average of 3 times. Proceed to the next step on the basis of ensuring that the flange 2 is perpendicular to the pipe body 1.

[0053] Secondly, after ensuring the verticality and the parallel fit of the horizontal support plate to the pipe body, adjust the liftable legs 15 so that the lengths supported by the liftable legs 15 on both sides are the same, and allow the measuring assembly to rotate back and forth around the outer periphery of the pipe body 1 and the flange 2 (as shown in the figure). Figure 4As shown in the figure, the leveling plate 7 is moved along the outer circumference of the flange to center the spherical level bubble. At this time, the line on which the horizontal support plate 10 is located is the center line of the tube body 1. The reason for determining the center line before measuring the distance is to ensure that the light emitted by the laser rangefinder is parallel to the center line of the tube body and not deviated.

[0054] The same steps are followed to install another measuring assembly on the flange 2 at the other end of the tube body 1. The pair of horizontal support plates 10 are both located on the centerline. The laser rangefinders below the two opposing leveling mounting plates 7 are positioned diagonally, that is, on either side. This allows one laser rangefinder to be used with the opposing light barrier, while the other laser rangefinder is used with the other opposing light barrier, thereby obtaining two length measurement data simultaneously. Theoretically, the two measurements are identical, with some acceptable error margin.

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
