Description
Technical Field
[0001] This invention relates to the field of pipeline installation technology, and specifically to an integrated device for guiding, positioning and stress monitoring during pipeline installation. Background Technology
[0002] In the construction of combined heat and power (CHP) projects, the installation of CHP pipelines is one of the core procedures, and its installation accuracy directly affects the subsequent operating efficiency and safety of the entire system.
[0003] Currently, traditional cogeneration pipeline installation mostly relies on manual construction methods. Simple tools such as rulers, levels, and theodolites are needed for positioning during construction. However, during pipeline installation, the pipeline will generate stress due to temperature changes and external forces, especially high-pressure steam pipelines. Existing technologies lack real-time monitoring methods for pipeline stress, making it impossible to monitor stress concentration during pipeline installation. As a result, the installed pipelines are prone to fatigue damage, shortening their service life and increasing maintenance costs and safety hazards in cogeneration projects.
[0004] Therefore, there is an urgent need for an integrated device for guiding and positioning and stress monitoring during pipeline installation to solve the problem of inconvenient stress monitoring during the installation of cogeneration pipelines. Summary of the Invention
[0005] This invention addresses the shortcomings of existing technologies by providing an integrated device for guiding and positioning and stress monitoring during pipeline installation, thereby solving the problem of inconvenient stress monitoring during the installation of cogeneration pipelines.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An integrated guide positioning and stress monitoring device for pipeline installation is characterized by comprising a base, legs, a positioning plate, a stress monitoring mechanism, and two sets of clamping mechanisms. The stress monitoring mechanism includes at least three strain gauge sensors and a display screen. Each set of clamping mechanisms includes a side plate, a lateral adjustment mechanism, and a vertical adjustment mechanism. Two vertical legs are installed at intervals on the base, with the tops of the two legs respectively connected to the front and rear sides of the bottom of the positioning plate. A lateral adjustment mechanism is installed on the base on the left and right sides of the positioning plate. A vertical adjustment mechanism is connected to the movable end of each lateral adjustment mechanism that can move left and right. A side plate that can move vertically is connected to the movable end of each vertical adjustment mechanism that is arranged along the front-rear direction and located on the side of the positioning plate. At least one strain gauge sensor is provided on the opposite side of the two side plates and on the upper surface of the positioning plate. A display screen is provided at one end of the positioning plate, and the display screen is connected to the strain gauge sensors.
[0008] To optimize the above technical solution, the specific measures also include: Furthermore, the lateral adjustment mechanism includes a mounting base, a mounting plate, a connecting block, and a second screw. The mounting base is vertically mounted on a base below the positioning plate, and the two sets of lateral adjustment mechanisms each have a second screw extending in a direction away from each other on opposite sides of the mounting base. The bottom of one end of the mounting plate is slidably connected to the top of the mounting base, and the other end of the mounting plate is threadedly connected to the second screw through the connecting block. The vertical adjustment mechanism is mounted on the top of the mounting plate.
[0009] Furthermore, the ends of the second screws of the lateral adjustment mechanisms on both sides that are close to each other can rotatably pass through the mounting base and be connected by a coupling. Either second screw is used to rotate and synchronously drive the mounting plates of the lateral adjustment mechanisms on both sides to move closer to or further away from each other.
[0010] Furthermore, the lateral adjustment mechanism also includes an adjustment handle, and the end of the second screw away from the mounting base is provided with an adjustment handle for driving the second screw to rotate.
[0011] Furthermore, the vertical adjustment mechanism includes a connecting plate, a guide rod, and a first screw. The connecting plate is installed on the side wall of the side plate away from the positioning plate. The guide rod and the rotatable first screw are vertically spaced at intervals on the moving end of the horizontal adjustment mechanism. The connecting plate is slidably connected to the guide rod and threadedly connected to the first screw.
[0012] Furthermore, the vertical adjustment mechanism also includes a rotating handle. A ring-shaped rotating handle is fixedly fitted onto the outer side of the first screw, and the rotating handle is used to drive the first screw to rotate.
[0013] Furthermore, the upper end face of the positioning plate is provided with a recessed arc-shaped groove, the axial direction of which is set along the front-back direction, and the arc-shaped groove can be used to connect with the bottom side wall of the pipe placed in the front-back direction.
[0014] Furthermore, the upper surface of the positioning plate is a raised arc-shaped surface, the axis of the arc-shaped surface is set along the left and right direction, and the highest point of the arc-shaped surface is located in the middle of the positioning plate.
[0015] Furthermore, it also includes four sets of positioning components. The four sets of positioning components are installed in a rectangular array at the four corners of the positioning plate by the mounting bracket, and are located on the front and rear sides of the two side plates respectively. Each set of positioning components includes a first laser pointer and a second laser pointer whose transmitter is set far away from the positioning plate. On the front and rear sides of the positioning plate, the two first laser pointers located on the same side are symmetrically arranged in the front-rear direction and are arranged in the vertical direction on the same horizontal plane. The second laser pointers are all arranged parallel in the front-rear direction.
[0016] Furthermore, it also includes at least four lockable casters arranged in a rectangular array at the bottom of the base.
[0017] The beneficial effects of this invention are: This invention, through the inclusion of a stress monitoring mechanism and two sets of clamping mechanisms, allows for the on-demand activation of two sets of lateral adjustment mechanisms to adjust the spacing between the two side plates according to the dimensions of the pipe to be installed. It also allows for the on-demand activation of two sets of vertical adjustment mechanisms to adjust the clamping height of the two side plates according to the dimensions of the pipe to be installed. This ensures that the two side plates are stably clamped on both radial sides of the pipe to be installed, facilitating the guidance and positioning of the pipe, effectively improving the positioning accuracy of pipe installation, reducing pipe axis deviation, and lowering the risk of sealing failure at pipe connections. Simultaneously, the stress monitoring mechanism enables continuous stress monitoring of the pipe sides during installation, which is displayed on a screen, thus solving the problem of inconvenient stress monitoring during pipe installation.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] As attached Figure 1 and attached Figure 2As shown in the figure, an integrated guide positioning and stress monitoring device for pipeline installation according to an embodiment of the present invention includes a base 1, support legs 2, positioning plate 4, stress monitoring mechanism and two sets of clamping mechanisms. The stress monitoring mechanism includes at least three strain gauge sensors 19 and a display screen 3. Each set of clamping mechanisms includes a side plate 8, a horizontal adjustment mechanism and a vertical adjustment mechanism. Two vertical support legs 2 are installed at intervals on the base 1. The tops of the two support legs 2 are respectively connected to the front and rear sides of the bottom of the positioning plate 4. A horizontal adjustment mechanism is installed on the base 1 on the left and right sides of the positioning plate 4. The movable end of each horizontal adjustment mechanism that can move left and right is connected to a vertical adjustment mechanism. The movable end of each vertical adjustment mechanism that can move vertically is connected to a side plate 8 that is arranged in the front and rear direction and located on the side of the positioning plate 4. At least one strain gauge sensor 19 is provided on the opposite side of the two side plates 8 and the upper surface of the positioning plate 4. A display screen 3 is provided at one end of the positioning plate 4, and the display screen 3 is connected to the strain gauge sensor 19.
[0022] This invention, through the inclusion of a stress monitoring mechanism and two sets of clamping mechanisms, allows for the on-demand activation of two sets of lateral adjustment mechanisms to adjust the spacing between the two side plates 8 according to the dimensions of the pipe to be installed. It also allows for the on-demand activation of two sets of vertical adjustment mechanisms to adjust the clamping height of the two side plates 8 according to the dimensions of the pipe to be installed. This ensures that the two side plates 8 are stably clamped on both radial sides of the pipe to be installed, facilitating the guidance and positioning of the pipe, effectively improving the positioning accuracy of pipe installation, reducing pipe axis deviation, and lowering the risk of sealing failure at pipe connections. Simultaneously, the stress monitoring mechanism enables continuous stress monitoring of the pipe sides during installation, which is displayed on the screen 3, thus solving the problem of inconvenient stress monitoring during pipe installation.
[0023] This invention provides a device capable of guiding and positioning cogeneration pipelines and monitoring stress, significantly improving production efficiency and ensuring pipeline installation quality and operational safety. The device has a simple overall structure, is easy to operate, and is suitable for installing cogeneration pipelines of different diameters, making it highly practical.
[0024] Specifically, in use, the changes in strain gauge sensor 19 can intuitively reflect the changes in pipeline stress, and the data is transmitted to the terminal device via the transmission module. The terminal device then transmits the processed data to the display screen for display. The transmission module can wirelessly transmit the collected stress data to the remote monitoring terminal device, realizing remote real-time monitoring of pipeline stress. This allows construction personnel to promptly grasp the pipeline stress situation, detect stress concentration phenomena in a timely manner, take corresponding measures, avoid pipeline fatigue damage, extend pipeline service life, and reduce project maintenance costs and safety hazards. In the above scheme, the stress monitoring element of strain gauge sensor 19 can have an arc-shaped structure.
[0025] Specifically, strain gauge sensor 19 can be a BX120-3AA type resistance strain gauge, connected to the data acquisition unit via wires. The data acquisition unit uses a NIcDAQ type data acquisition card and has a built-in 4G wireless transmission module. The data acquisition unit is electrically connected to display screen 3 via wires, and display screen 3 is an LCD screen. The wireless transmission module can wirelessly transmit the stress data acquired by the data acquisition unit to a remote monitoring terminal, which can be a computer or a smartphone.
[0026] As attached Figure 3 and attached Figure 4 As shown, in a specific embodiment based on the above, the lateral adjustment mechanism includes a mounting base 17, a mounting plate 13, a connecting block 14, and a second screw 16. The mounting base 17 is vertically mounted on the base 1 below the positioning plate 4, and the two sets of lateral adjustment mechanisms have a second screw 16 extending in a direction away from each other on opposite sides of the mounting base 17. The bottom of one end of the mounting plate 13 is slidably connected to the slot on the top of the mounting base 17 by a locking block. The other end of the mounting plate 13 is threadedly connected to the second screw 16 by the connecting block 14. The vertical adjustment mechanism is mounted on the top of the mounting plate 13.
[0027] In this embodiment, the mounting plate 13 is slidably connected to the mounting base 17, which restricts the mounting plate 13, as the moving end, to only slide left and right. It is driven by the rotated second screw 16, so that the mounting plate 13 and the vertical adjustment mechanism thereon can adjust the displacement in the left and right directions.
[0028] In a further specific embodiment based on the above, the adjacent ends of the second screws 16 of the two lateral adjustment mechanisms can rotatably pass through the mounting base 17 and be connected by a coupling. Either second screw 16 is used to rotate and synchronously drive the mounting plates 13 of the two lateral adjustment mechanisms to move closer to or further away from each other. This facilitates the synchronous driving of the second screws 16 on both sides.
[0029] In a further specific embodiment based on the above, the lateral adjustment mechanism further includes an adjustment handle 15, and the end of the second screw 16 away from the mounting base 17 is provided with an adjustment handle 15 for driving the second screw 16 to rotate.
[0030] In another specific embodiment based on the above, the vertical adjustment mechanism includes a connecting plate 9, a smooth rod 10 and a first screw 11. The connecting plate 9 is installed on the side wall of the side plate 8 away from the positioning plate 4. The smooth rod 10 and the rotatable first screw 11 are vertically spaced apart on the moving end of the horizontal adjustment mechanism. The connecting plate 9 is slidably connected to the smooth rod 10 and threadedly connected to the first screw 11.
[0031] In this embodiment, the connecting plate 9 can be driven to adjust its vertical height position along the light rod 10 under the constraint of the light rod 10 by rotating the first screw 11.
[0032] In a further specific embodiment based on the above, the vertical adjustment mechanism also includes a rotating handle 12. A ring-shaped rotating handle 12 is fixedly sleeved on the outer side of the first screw 11. The rotating handle 12 is used to drive the first screw 11 to rotate.
[0033] In another specific embodiment based on the above, the upper end face of the positioning plate 4 is provided with a recessed arc-shaped groove, the axial direction of which is set along the front-back direction, and the arc-shaped groove can be used to dock with the bottom side wall of the pipe placed along the front-back direction.
[0034] In another specific embodiment based on the above, the upper surface of the positioning plate 4 is a raised arc-shaped surface, the axis of the arc-shaped surface is set along the left and right direction, and the highest protrusion of the arc-shaped surface is located in the middle of the positioning plate 4.
[0035] As attached Figure 5 As shown, in another specific embodiment based on the above, four sets of positioning components are also included. The four sets of positioning components are respectively installed in a rectangular array at the four corners of the positioning plate 4 by the mounting bracket 5, and are respectively located on the front and rear sides of the two side plates 8. Each set of positioning components includes a first laser pointer 6 and a second laser pointer 7 whose transmitter is set far away from the positioning plate 4. On the front and rear sides of the positioning plate 4, the two first laser pointers 6 located on the same side are symmetrically arranged in the front and rear direction and are arranged in the vertical direction on the same horizontal plane. The second laser pointers 7 are all arranged parallel in the front and rear direction.
[0036] In this embodiment, there are two laser pointers, one perpendicular and one parallel. The first laser pointer 6, which is at a 45° angle to the second laser pointer 7, emits laser light from both ends and can work in conjunction with the laser light emitted by the second laser pointer 7, which is set in parallel. This allows the construction personnel to assist in positioning during the measurement process, which is beneficial for the measurement and guidance of pipelines.
[0037] In another specific embodiment based on the above, at least four lockable casters are also included, arranged in a rectangular array at the bottom of the base 1. This facilitates the overall movement and adjustment of the device as needed.
[0038] In another specific embodiment based on the above, an anti-slip pad can be provided at the bottom of the base 1. The anti-slip pad is made of rubber and has anti-slip texture on the bottom to enhance the stability of the base 1 on the construction surface and prevent the device from shifting during pipe installation. The anti-slip pad is connected to the base 1 by threads, and a nut adjustment hole is provided at the bottom. The base 1 can also be equipped with a gravity sensor as needed. The gravity sensor is fixed to the base 1 and can display real-time data on a display screen.
[0039] In another specific embodiment based on the above, an elastic buffer layer can be provided on the upper end surface of the positioning plate 4 and the side wall of the side plate 8, and the strain gauge sensor 19 can be attached to the elastic buffer layer. The elastic buffer layer can be made of polyurethane foam with a thickness of 5-8mm, which can both buffer and prevent the outer wall of the pipe from being scratched, and enable the strain gauge sensor 19 to better sense the stress changes in the pipe.
[0040] In the above scheme, the rotational connection between components can be achieved through bearing connection.
[0041] One specific embodiment of the present invention is as follows: During the installation of cogeneration pipelines, place this device on the ground below the pipeline installation location; adjust the two sets of horizontal adjustment mechanisms according to the size of the pipeline to be installed until the distance between the two side plates 8 is greater than the diameter of the pipeline, then place the pipeline to be installed on the upper surface of the positioning plate 4, and then adjust the vertical adjustment mechanism as needed until the two side plates 8 are respectively located at the specified height on the side of the pipeline to be installed, and then adjust the horizontal adjustment mechanism in the opposite direction so that the two side plates 8 complete the clamping and positioning of the pipeline to be installed; Then, the position of the entire device is adjusted as needed to connect the pipe openings of the two pipes before pipe installation. During pipe installation, strain gauge sensor 19 senses the stress changes in the pipe in real time and transmits the stress signal to display screen 3 to display stress data in real time. Construction personnel can monitor the stress of the pipe in real time through display screen 3. If the stress exceeds the preset threshold, adjustment measures can be taken in time.
