Description

Technical Field

[0001] This utility model relates to the field of equipment installation, and in particular to an auxiliary device for equipment installation parallelism. Background Technology

[0002] During equipment installation, it is crucial to control the parallelism between two components. For example, in the laying of pipelines in a nuclear power plant, due to the large diameter of the pipes, large flanges are required to connect the two pipes. The consistency of the tightening depth of multiple bolts on the flange circumference affects the quality of the flange connection. When the tightening depth of multiple bolts is inconsistent, the sealing surfaces of the two flanges are not parallel, resulting in uneven stress on the gasket between the two flanges. This can damage the gasket or cause seal failure, leading to reinstallation work.

[0003] In the existing technology, after each time a bolt is tightened around the flange circumference, the installer uses a vernier caliper to check multiple inspection points set around the flange and compares whether the spacing of the multiple inspection points is the same. If the spacing of the multiple inspection points is different, it is adjusted according to the actual situation. If the spacing of the multiple inspection points is the same, it indicates that the two flanges are parallel.

[0004] The existing inspection method cannot detect the distance between the two flanges in real time; an inspection must be performed after all the bolts on each turn have been tightened. Summary of the Invention

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] Reference Figures 1 to 4This utility model provides an auxiliary device for equipment installation parallelism, including a measuring panel 7, a data processing system, a display system, multiple connectors and multiple laser displacement sensors 1; the connectors are used to connect to the first flange 4, the connectors are used to connect to the first measuring surface, the first measuring surface is provided with multiple detection points, and each laser displacement sensor 1 is installed at one detection point.

[0037] The parallelism assist device for equipment installation in this embodiment is applied to pipeline installation, specifically during the flange docking process of two pipelines. One pipeline is designated as the first pipeline, and its flange as the first flange; the other pipeline is designated as the second pipeline, and its flange as the second flange. The first measuring surface is the surface of the first flange 4 closest to the second flange 5. The surface of the second flange 5 closest to the first flange forms the measuring panel 7, and the surface of the second flange closest to the first flange forms the second measuring surface.

[0038] Each laser displacement sensor 1 is connected to the first flange 4 via a connector. Multiple laser displacement sensors 1 are spaced apart around the axis of the first flange 4. Each laser displacement sensor 1 measures the distance between its location at the detection point and a point on the second measuring surface directly opposite the detection point. In other words, the laser displacement sensor is installed at the detection point, and the laser shines on the second measuring surface. The laser displacement sensor 1 is used to detect the distance between the detection point and the point where the laser is directly irradiated. The display system and the laser displacement sensors 1 are respectively connected to the data processing system.

[0039] In this embodiment, the data processing system is used to compare the value of each laser displacement sensor 1 with the preset value, and the display system is used to display the result of the comparison by the data processing system.

[0040] The first flange 4 is fixed to one end of the first pipe 2, and the second flange 5 is fixed to one end of the second pipe 3. The end faces of the first flange 4 and the second flange 5 are wiped clean. After aligning the first flange 4 with the second flange 5, a flange sealing gasket is added, and the bolts are tightened. Multiple laser displacement sensors 1 are then installed around the central axis of the first flange 4, and the multiple laser displacement sensors 1 are stably connected via connectors. Preset values ​​are pre-entered into the data processing system, and then the bolts are tightened. Each laser displacement sensor 1 detects the distance between the two flanges in real time and sends the detected value to the data processing system. The data processing system compares the preset values ​​with the detected values ​​of each laser displacement sensor 1 and sends the comparison result to the display system. The installer adjusts the tightness of the bolts based on the detection data displayed on the display system.

[0041] For example, the distance between two flanges needs to be 80mm. After the installer initially connects the first flange 4 and the second flange 5, the distance between the two flanges is obviously greater than 80mm. Multiple laser displacement sensors 1 are then installed. The preset value of 80mm is entered into the data processing system. The installer tightens each bolt on the flange. When the value of one of the laser displacement sensors 1 reaches the preset value, the tightening of the bolts near that laser displacement sensor 1 is stopped until all the values ​​of the laser displacement sensors 1 reach the preset value.

[0042] If the value of one of the laser displacement sensors 1 is greater than 80mm, it indicates that the bolt is not yet in place. The installer should observe the real-time data of the display system while tightening the bolts near the laser displacement sensor 1 until the value of the laser displacement sensor 1 equals the preset value.

[0043] If the value of one of the laser displacement sensors 1 is less than 80mm, it indicates that the bolt has been overtightened. The installer should observe the real-time data of the display system while loosening the bolts near the laser displacement sensor 1 until the value of the laser displacement sensor 1 is equal to the preset value.

[0044] When tightening bolts, personnel can observe the real-time values ​​on the display system to identify which laser displacement sensor 1 has not yet reached or exceeded the preset value, and thus tighten or loosen the corresponding bolts on the flange accordingly.

[0045] In some embodiments, after comparing the detection values ​​of each laser displacement sensor 1, the data processing system performs preliminary addition and subtraction calculations and displays the difference between the detection values ​​of the laser displacement sensor 1 and the preset values, thereby making it easier for installers to understand the magnitude of the difference, so that installers can apply force to tighten or loosen the bolts according to the magnitude of the difference. For example, if the preset value is 80mm, one laser detector (referred to as laser detector A) measures 85mm, and another laser detector (referred to as laser detector B) measures 75mm, the data processing system compares the measured value of laser detector A with the preset value and calculates that the measured value of laser detector A minus the preset value is +5mm. Based on this +5mm value, the installer determines that the distance between the two flanges at laser detector A exceeds the preset value, and the bolts near laser detector A need to be tightened by 5mm. Simultaneously, the data processing system compares the measured value of laser detector B with the preset value and calculates that the measured value of laser detector B minus the preset value is -5mm. Based on this -5mm value, the installer determines that the distance between the two flanges at laser detector B is less than the preset value, and the bolts near laser detector B need to be loosened by 5mm.

[0046] In this embodiment, the data processing system can be a PLC controller or an MCU controller, and the display system is a monitor. In some embodiments, the data processing system can also be a computer or other devices.

[0047] In other embodiments, after the laser displacement sensor is installed on the first measuring surface, the bolts are tightened, and the display interface of the display system will display the distance values ​​between the first and second measuring surfaces in real time. The display interface uses numerical and curve methods, and the distance and difference between different measuring points can be intuitively seen through numerical and curve changes. This allows for a very intuitive reading of the distance deviation between the first and second measuring surfaces, thereby guiding the operator to pre-tighten or loosen the bolts in a certain area for adjustment. For high-precision deviation requirements, a preset value for the distance deviation between any two points can also be set. When the actual deviation value reaches the preset value during operation, an alarm indication is triggered to alert the operator, thereby reducing equipment damage caused by error values.

[0048] As an example, the connector includes multiple magnetic elements, each corresponding to a multiple laser displacement sensor 1. The magnetic elements are fixed to their corresponding laser displacement sensor 1 and are adsorbed onto the surface of the first flange 4 near the second flange 5.

[0049] A typical flange consists of two regions: an inner ring and an outer ring. The outer ring region has multiple through holes for bolts to pass through. The inner ring region has a protruding end face that serves as a sealing surface. The sealing surfaces of the two flanges and the flange gasket sandwiched between them result in a distance between the two flanges that is larger than the size of the laser displacement sensor 1. In this case, to simplify the detection operation, the laser displacement sensor 1 is directly attached to the outer ring region of the first flange 4 using a magnet. The laser displacement sensor 1 is used to measure the distance between the outer ring region of the second flange 5 and the outer ring region of the first flange 4. This detection method can only be used when the distance between the two flanges is relatively large.

[0050] As an example, the laser displacement sensor 1 and the display system are connected to the data processing system via wires. Wired connections offer low latency, stable signal transmission, and improved installation efficiency.

[0051] Specifically, the wires include a first wire and a second wire. One end of the first wire is connected to the laser displacement sensor 1, and the other end is provided with an aviation male connector. One end of the second wire is connected to the display system, and the other end of the second wire is provided with an aviation male connector. The data processing system is provided with two aircraft female connectors. Through the connection between the aviation male connector and the aircraft female connector, the laser displacement sensor 1 and the data processing system, as well as the display system and the data processing system, can be quickly connected respectively.

[0052] As an example, the device installation parallelism aid also includes a first housing, within which a data processing system and a display system are housed. A display window is provided on the first housing, and the display system is installed within the display window. By integrating the data processing system and the display system into a single unit, it facilitates portability.

[0053] As an example, three laser displacement sensors 1 are provided, and the lines connecting the three laser displacement sensors 1 form a closed triangle when projected onto the first measuring surface. If only one laser displacement sensor 1 is used, only one detection point can be detected. To ensure that every point between the two flanges is equally spaced, the laser displacement sensor 1 needs to be moved multiple times after each bolt tightening to confirm that other detection points are equal to the preset value; otherwise, it is easy to cause misalignment, tilting, or even displacement. Even with two laser displacement sensors 1, it is still impossible to guarantee equal spacing between every detection point between the two flanges. Therefore, the presence of three laser displacement sensors 1 provides multi-point detection, ensuring equal spacing between the two flanges, and improving the accuracy and stability of installation and detection. Three laser displacement sensors 1 are the most suitable number, offering the advantage of controlling costs while ensuring measurement effectiveness.

[0054] As an example, the equipment installation parallelism auxiliary device also includes an alarm. The alarm signal is connected to the data processing system so that the alarm can sound after the values ​​of all laser displacement sensors 1 compared by the data processing system are the same as the preset values. When the values ​​of all laser displacement sensors 1 are equal to the preset values, the two flanges are parallel and the spacing between the facing surfaces of the two flanges is the same as the engineering requirements. After the data processing system compares the results, it transmits a signal to the alarm. After receiving the signal, the alarm sounds an alarm, at which point the installation workers stop their work and the installation is completed.

[0055] In one embodiment, a first measuring surface is disposed on a first flange, and a measuring panel is disposed on a second flange; the connecting member includes a mounting ring plate 6 and a plurality of magnets, the mounting ring plate 6 is ferromagnetic, the mounting ring plate 6 is disposed on the outer peripheral surface of the first flange 4, the plurality of magnets and the plurality of laser displacement sensors 1 correspond one-to-one, and each magnet is fixed on its corresponding laser displacement sensor 1; the measuring panel 7 is annular, the measuring panel 7 is disposed on the outer peripheral surface of the second flange 5, and the interval between the measuring panel 7 and the mounting ring plate 6 is greater than the length of the laser displacement sensor 1.

[0056] In engineering projects, it is common to encounter situations where, after connecting flanges on two pipelines, the distance between the two flanges is less than that of the laser displacement sensor 1. In this case, the laser displacement sensor 1 cannot be placed on the outer ring area of ​​the flange. Therefore, an additional mounting ring plate 6 is fixed to the first flange 4, and a measuring panel 7 is fixed to the second flange 5. This ensures that after the flanges on the two pipelines are connected, the distance between the mounting ring plate 6 and the measuring panel 7 is still greater than the size of the laser displacement sensor 1. Since the surface of the mounting ring plate 6 near the second flange 5 is parallel to the surface of the first flange 4 near the second flange 5, and the surface of the measuring panel 7 near the first flange 4 is parallel to the surface of the second flange 5 near the first flange 4, the parallelism between the first flange 4 and the second flange 5 can be determined by detecting whether the mounting ring plate 6 and the measuring panel 7 are parallel. Furthermore, the distance between the first flange 4 and the second flange 5 can be calculated using the distance between the mounting ring plate 6 and the measuring panel 7.

[0057] Reference Figure 3 As an example, the mounting ring plate 6 includes a first arc plate 601 and a second arc plate 602, which are detachably connected so that the first arc plate 601 and the second arc plate 602 are assembled into the mounting ring plate 6.

[0058] As an example, the measurement panel 7 includes a first sub-plate and a second sub-plate, which are detachably connected to form the measurement panel 7.

[0059] In this embodiment, the mounting ring plate 6 is installed as follows: a rotating seat 61 is fixed to the first end of the first arc plate 601, and a rotating shaft 62 is fixed to the first end of the second arc plate 602. The first ends of the first arc plate 601 and the first ends of the second arc plate 602 are pivotally connected through the rotating shaft 62 and the rotating seat 61. A first plate 63 is provided on the second end of the first arc plate 601, and the first plate 63 has a first through hole. A second plate 64 is provided on the second end of the second arc plate 602, and the second plate 64 has a second through hole. When the first arc plate 601 and the second arc plate 602 rotate around the rotating shaft 62 and are spliced ​​to form the mounting ring plate 6, the first plate 63 and the second plate 64 are parallel, and the first through hole and the second through hole are coaxial. Bolts are inserted and nuts are tightened, and the first plate 63 and the second plate 64 are connected through the bolts and nuts, so that the mounting ring plate 6 spliced ​​by the first arc plate 601 and the second arc plate 602 remains stable and can be continuously fitted onto the flange.

[0060] Reference Figure 4In other embodiments, a first fixing plate 65 is provided on the first end of the first arc plate 601, and a first through hole is provided on the first fixing plate 65; a second fixing plate 66 is provided on the second end of the second arc plate 602, and a second through hole is provided on the second fixing plate 66; a third fixing plate 67 is provided on the first end of the third arc plate, and a third through hole is provided on the third fixing plate 67; and a fourth fixing plate 68 is provided on the second end of the fourth arc plate, and a fourth through hole is provided on the fourth fixing plate 68. The first end of the first arc plate 601 and the first end of the second arc plate 602 are aligned, and the second end of the second arc plate 602 is aligned with the second arc plate 602, so that the first arc plate 601 and the second arc plate 602 are assembled to form the mounting ring plate 6. Then, bolts are inserted into the first and third through holes and connected with nuts to connect the first ends of the first arc plate 601 and the first ends of the second arc plate 602 into one unit. Another bolt is inserted into the second and fourth through holes and connected with nuts to connect the second ends of the second arc plate 602 into one unit, thus connecting the first arc plate 601 and the second arc plate 602 into one unit.

[0061] In this embodiment, the measuring panel can be detachably connected in the same way as the first measuring surface, which will not be described in detail here.

[0062] Reference Figure 5 and Figure 6 In one embodiment, the mounting ring plate includes a chain 8 and a locking mechanism. The chain 8 is linear, and the locking mechanism includes a base 95, a slider 93, and a screw 94. The base 95 is fixed to one end of the chain 8, and the slider 93 is adapted to connect to the other end of the chain 8. The slider 93 is slidably connected to the base 95, and the sliding direction of the slider 93 is parallel to the length direction of the chain 8. The slider 93 is provided with a threaded hole, and the screw 94 is threadedly connected to the slider 93. The chain 8 and the locking mechanism can form a closed ring structure.

[0063] In this embodiment, the chain 8 includes a plurality of first arc-shaped plates 81 and a plurality of second arc-shaped plates 82. The first arc-shaped plates 81 and the second arc-shaped plates 82 are alternately arranged. The two ends of the second arc-shaped plates 82 are rotatably connected to the adjacent first arc-shaped plates 81, so that the plurality of first arc-shaped plates 81 and the plurality of second arc-shaped plates 82 form the chain 8.

[0064] As an example, the locking mechanism also includes a locking plate and a lever plate 92. One end of the locking plate is bent toward the chain 8 and rotatably connected to the end of the chain 8 away from the base 95. The other end of the locking plate is bent toward the lever plate 92 and rotatably connected to the lever plate 92. The end of the lever plate 92 away from the locking plate rotates the slider 93.

[0065] The base 95 is fixed to one end of the chain 8 and rotatably connected to the first arc-shaped plate 81 at that end. The locking plate is fixed to the other end of the chain 8 and rotatably connected to the second arc-shaped plate 82 at that end. In this embodiment, the chain 8 is arranged around the first flange, and the tension of the chain 8 is adjusted by the screw 94 to ensure that the chain 8 and the locking mechanism are firmly fixed to the first flange. This method allows the mounting ring plate to be adapted to flanges of different diameters, enabling the mounting ring plate to be installed on the outer circumferential surface of flanges of different diameters. In this embodiment, both the chain 8 and the locking mechanism are made of ferromagnetic material, allowing the laser displacement sensor to be directly adsorbed onto the chain 8 or the locking mechanism via the connector.

[0066] In this embodiment, the structure of the measuring panel is the same as that of the mounting ring plate, so that the measuring panel can also be adapted to flanges of different diameters.

[0067] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
