[0035] Example 1

[0036] Reference Figure 1-Figure 4 The present embodiment provides an online detection device for the coaxiality of a pipeline connector, including a laser emitter 100, a transparent plate 300 and a display baffle 500. The laser emitter 100 is used to be installed on a first pipeline 200. The transparent plate 300 is used to be installed on a second pipeline 400 connected to the first pipeline 200. A light-transmitting slit 311 is provided on the transparent plate 300. The light-transmitting slit 311 is used to pass a laser beam emitted by the laser emitter 100. The display baffle 500 is used to be installed on the second pipeline 400. The transparent plate 300 is located between the display baffle 500 and the laser emitter 100. The display baffle 500 is used to display a light spot formed after the laser beam passes through the light-transmitting slit 311.

[0037] In this embodiment, when it is necessary to detect the coaxiality between two pipes located in a narrow space, the laser emitter 100, the transparent plate 300 and the display baffle 500 are first installed on the corresponding first pipe 200 and the second pipe 400 as required, that is, by setting the laser emitter 100 on the first pipe 200, and setting the transparent plate 300 and the display baffle 500 on the second pipe 400, when the laser emitter 100 emits a laser beam, if the laser beam can pass through the light-transmitting slit 311 of the transparent plate 300 and is displayed on the display baffle 500 to form a light spot, it means that the two pipes are assembled properly, thereby achieving the purpose of detecting the coaxiality. On the contrary, if no light spot is formed on the display baffle 500, it means that the coaxiality deviation of the two pipes is large and the assembly is unqualified. The device is small in size and can be flexibly used for coaxiality detection between pipes in various narrow spaces. The operation difficulty is also relatively low, and the detection result is intuitive and reliable.

[0038] As an optional embodiment, three groups of installation components 600 are further included. The laser emitter 100 is movably connected to the first pipe 200 through corresponding installation components 600, and the transparent plate 300 and the display baffle 500 are movably connected to the second pipe 400 through corresponding installation components 600.

[0039] In this embodiment, the laser emitter 100, the transparent plate 300 and the display baffle 500 can all be installed on the corresponding first pipe 200 or the second pipe 400 through the installation component 600, which is convenient for assembly and disassembly.

[0040] As an optional implementation, the light-transmitting slit 311 is a circular arc groove, and the center of the circular arc groove is located on the axis line of the second pipe 400 .

[0041] In this embodiment, based on the design of the light-transmitting slit 311 in the form of an arc groove, the passage detection of the laser beam can be performed in the area of ​​the light-transmitting slit 311. Therefore, during installation, it is not necessary for the laser emitter 100, the transparent plate 300 and the display baffle 500 to be completely aligned. The installation is quick and convenient, with low installation requirements, low operating difficulty, low professional requirements, high versatility, and the laser emitter 100 can be rotated around the first pipe 200 to detect the coaxiality of multiple points. During the detection process, the installation component 600 equipped with the laser emitter 100 can be rotated around the first pipe 200 for multiple corresponding angles, and it is observed with the naked eye whether there is a light spot on the display baffle 500 after each rotation, thereby realizing verification of whether the coaxiality meets the standard through multi-point detection, and having higher detection accuracy.

[0042] It should be noted that the width of the light-transmitting slit 311 is made according to the coaxiality tolerance requirement. As long as the laser can pass through the light-transmitting slit 311, it can be said that the coaxiality of the two pipes is within the tolerance range, that is, as long as the light spot can be observed on the display baffle, it can be said that the assembly is qualified, thereby achieving the design purpose of detecting coaxiality.

[0043] As an optional embodiment, the installation assembly 600 includes a connecting base 610, a bracket 620, a locking belt 630 and a limiting mechanism. The connecting base 610 is used to be set on the first pipe 200 or the second pipe 400, the top of the connecting base 610 is used to install the laser emitter 100 or the transparent plate 300 or the display baffle 500, the bracket 620 is set at one side end of the connecting base 610, one end of the locking belt 630 is connected to the bracket 620, and the limiting mechanism is used to fix the other end of the locking belt 630 to the other side end of the connecting base 610.

[0044] In this embodiment, during installation, the connecting base 610 is assembled on the top of the first pipe 200 or the second pipe 400 to support the laser emitter 100 or the transparent plate 300 or the display baffle 500, and the locking belt 630 is passed around the bottom of the first pipe 200 or the second pipe 400 and pulled to the other side of the connecting base 610, and then the other end of the locking belt 630 is fixed to the other side end of the connecting base 610 through the limiting mechanism, so as to achieve the effect of quick installation, simple installation and precise positioning. At the same time, after installation, the locking belt 630 can rotate around the first pipe 200 or the second pipe 400 to facilitate multi-point detection. Therefore, the installation component 600 not only has the function of installing and supporting the laser emitter 100 or the transparent plate 300 or the display baffle 500, but also should have the function of being flexible to rotate after installation, so as to meet the needs of multi-point detection.

[0045] It should be noted that, in addition to the structure of the mounting assembly 600 shown in this embodiment, other structures of the mounting assembly 600 that can simultaneously support the laser emitter 100 or the transparent plate 300 or the display baffle 500 and can be flexibly rotated are applicable. Here, the locking belt 630 is a belt, which has an elastic tightening effect and meets the use requirements.

[0046] As an optional implementation, the limiting mechanism includes a locking rod 640 , and a first positioning hole and a second positioning hole cooperating with the locking rod 640 are respectively provided on the side end of the connecting base 610 and the locking belt 630 .

[0047] In this embodiment, when the locking belt 630 needs to be fixed, the second positioning hole on the locking belt 630 and the first positioning hole at the side end of the connection base 610 are assembled in place, and the locking rod 640 is passed through the second positioning hole and the first positioning hole in sequence, so that fast fixing can be completed and disassembly is also convenient. Here, the locking rod 640 and the first positioning hole can form a threaded matching structure, and the locking is more secure and stable.

[0048] As an optional implementation, a plurality of second positioning holes are provided on the locking belt 630 , and the plurality of second positioning holes are arranged along the length direction of the locking belt 630 .

[0049] In this embodiment, by matching the second positioning holes at different positions on the locking belt 630 with the first positioning holes on the side end of the connecting base 610, it can be installed on pipes of different diameters, so that it can be suitable for coaxiality detection of various types of pipes, thereby improving versatility.

[0050] As an optional embodiment, the bottom surface of the connecting base 610 is an arc surface that can fit with the first pipe 200 or the second pipe 400, which has better fit and is not easy to slide and shift after being fixed. The bottom surface of the connecting base 610 can also be designed as an arc with a larger radius, so as to be compatible with pipes of various diameters and improve versatility.

[0051] As an optional embodiment, the transparent plate 300 includes a light-transmitting plate 310 and a connecting rod 320. The light-transmitting slit 311 is provided on the light-transmitting plate 310, and the light-transmitting plate 310 is connected to the top of the corresponding connecting base 610 through the connecting rod 320. The connecting rod 320 is detachably connected to the top of the connecting base 610; or, the connecting rod 320 is fixedly connected to the top of the connecting base 610, and the connecting rod 320 is a telescopic rod.

[0052] In this embodiment, the light-transmitting plate 310 is used to pass the laser beam of the laser emitter 100. Here, the light-transmitting plate 310 can be disassembled and connected to the top of the connecting base 610 through the connecting rod 320, or the connecting rod 320 is a telescopic rod. When the diameters of the conduits at both ends of the connecting piece to be detected are inconsistent, the device should be installed on the standard rod first, and then the height of the light-transmitting plate 310 should be adjusted by the telescopic rod or the light-transmitting plate 310 of the corresponding height should be replaced so that the laser path is aligned with the center of the light-transmitting slit 311 to ensure height consistency.

[0053] It should be noted that when the connecting rod 320 and the connecting base 610 are a detachable connection structure, a mounting hole can be opened at the top of the connecting base 610, and a mounting hole matching the connecting rod 320 is also opened at the bottom of the light-transmitting plate 310. When replacing the light-transmitting plates 310 of different heights, it is only necessary to replace the connecting rod 320 of the corresponding length each time and install it at the bottom of the light-transmitting plate 310, and then install it on the top of the connecting base 610, which is low in cost. When the connecting rod 320 is fixedly connected to the top of the connecting base 610, and the connecting rod 320 is a telescopic rod, the telescopic rod is an electric push rod or other device with a telescopic function, which is convenient for automatic adjustment and convenient operation.

[0054] As an optional implementation, the display baffle 500 is a fluorescent plate coated with fluorescent powder, which can improve the display effect of the laser beam. The staff only needs to observe the laser distribution on the fluorescent plate to determine whether the coaxiality is qualified. It is simple and fast and has low requirements for ambient light.

[0055] Example 2

[0056] Reference Figure 1-Figure 4This embodiment provides a detection method, based on an online detection device for coaxiality of a pipe connector described in the embodiment, comprising the following steps:

[0057] Install and debug the laser emitter 100, the transparent plate 300 and the display baffle 500 on the corresponding pipeline;

[0058] Start the laser transmitter 100 and observe whether a light spot appears on the display baffle 500;

[0059] Rotate the mounting assembly 600 connected to the laser emitter 100 and continue to observe whether a light spot appears on the display baffle 500;

[0060] Continue to rotate the mounting assembly 600 connected to the laser emitter 100 at least once, and observe whether a light spot appears on the display baffle 500;

[0061] If it is observed that a light spot appears on the display baffle 500 each time, it is judged that the coaxiality between the pipes is qualified; if it is observed that no light spot appears on the display baffle 500, it is judged that the coaxiality between the pipes is unqualified.

[0062] In this embodiment, based on the design of the light-transmitting slit 311 in the form of an arc groove, the laser beam can be detected in the area of ​​the light-transmitting slit 311. During the detection process, the mounting assembly 600 with the laser emitter 100 can be rotated around the first pipe 200 for multiple times at corresponding angles, and the naked eye can be observed to see whether there is a light spot on the display baffle 500 after each rotation. The operation is flexible, so that the coaxiality can be verified by multi-point detection to be up to standard, which is more accurate and scientific. During the detection process, as long as no light spot appears in one of the detections, the coaxiality is judged to be unqualified, and there is no need to perform the next detection.

[0063] It should be noted that during the inspection, generally at least three inspections are performed, that is, the laser emitter 100 is inspected once at different positions of the first pipeline 200. Depending on the coaxiality requirements between pipelines, the number of inspections may reach more than three times. Here, a comparison table of the number of inspections and the coaxiality requirements can be formulated based on experience to provide guidance for the operator's inspection.
