Description

Technical Field

[0001] The present invention relates to the field of steam-water pipeline supports in thermal power plants, and particularly to a steam-water pipeline support for thermal power plants that is convenient for installation and an installation method thereof. Background Art

[0002] The steam-water pipeline supports in thermal power plants are structural members used to support and fix steam-water pipelines. Their main functions include supporting the weight of the pipelines, balancing the reaction forces of the media, restricting displacements, and preventing vibrations. These supports ensure that the stresses in the pipeline system remain within the design range, thereby ensuring that the pipelines can reach the design life. The steam-water pipeline supports in thermal power plants are widely used in high-temperature and high-pressure environments such as boiler feedwater systems, steam systems, condensate systems, and heat transfer medium systems. The following technical parameters need to be considered during design: Design load: including the impact loads and temperature changes suffered by the pipelines during operation; Support materials: need to have characteristics such as corrosion resistance, wear resistance, and high temperature resistance; Maintenance and servicing suggestions: To ensure the normal operation and extend the service life of the steam-water pipeline supports in thermal power plants, it is recommended to conduct regular inspections and maintenance; Check the corrosion and wear conditions of the supports and replace damaged components in a timely manner; Ensure the installation quality of the supports to avoid potential safety hazards caused by improper installation; Monitor the thermal expansion and contraction of the pipelines and adjust the expansion and contraction amounts of the spring supports and hangers to maintain the stability of the pipeline system.

[0003] However, in the prior art, when the steam-water pipeline transports high-temperature and high-pressure steam, due to the increase in temperature, the pipeline material will expand, resulting in an increase in the pipeline length and generating thermal expansion and thermal displacement. At this time, when the steam-water pipeline expands, it will squeeze the pipeline support, easily causing the steam-water pipeline to be damaged due to excessive pressure. Summary of the Invention

[0004] The purpose of the present invention is to provide a steam-water pipeline support for thermal power plants that is convenient for installation and an installation method thereof to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: A steam-water pipeline support for thermal power plants that is convenient for installation includes a first main body and a second main body. Vertical grooves are provided on both side walls of the first main body and the second main body. Threaded rods are arranged inside the vertical grooves. Grooves are provided at the corner positions of the first main body and the second main body. Nuts are arranged at both ends of the threaded rods and inside the grooves. Buffer grooves are provided inside the first main body and the second main body, and a buffer mechanism is arranged inside the buffer grooves; The buffer mechanism includes four groups of clamping plates. Arc-shaped plates are arranged on the inner side walls of the clamping plates. A number of positioning grooves are provided on the arc-shaped plates, and buffer plates are clamped inside the positioning grooves.

[0006] A further improvement of the present invention is that fixing grooves are provided at the corner positions of the clamping plates, and telescopic rods are arranged between the inner side walls of the fixing grooves and the inner side walls of the buffer grooves.

[0007] A further improvement of the present invention is that a return spring is wound around the middle position of the telescopic rod, limiting grooves are provided on both side walls of the clamping plate, and limiting plates are arranged on both inner side walls of the buffer groove.

[0008] A further improvement of the present invention is that the top of the buffer plate is arranged in a T shape, several groups of the buffer plates are arranged on the inner side wall of the arc-shaped plate through positioning grooves, and the clamping plate is movably arranged inside the buffer groove along the limiting groove by means of the cooperation of the telescopic rod, the return spring and the limiting plate.

[0009] A further improvement of the present invention is that the buffer plate is made of rubber material.

[0010] A further improvement of the present invention is that a lifting mechanism is arranged at the bottom of the first main body, the lifting mechanism includes a base and a bearing plate, two groups of transverse grooves are provided on the surfaces of the base and the bearing plate, and lead screws are arranged inside the transverse grooves.

[0011] A further improvement of the present invention is that a first slider is arranged on the lead screw and inside the transverse groove, second sliders are arranged at the corner positions on the base and the bearing plate, a support frame is arranged between the first slider and the second slider, and a hydraulic push rod is arranged at the upper end of the base.

[0012] A further improvement of the present invention is that the upper end of the bearing plate is fixedly connected to the bottom end of the first main body, a motor connected to the end of the lead screw is arranged inside the base, and the first slider slides inside the base along the transverse groove by means of the cooperation of the motor and the lead screw.

[0013] A further improvement of the present invention is that the support frame is arranged in a rotatable X shape, the end parts of the support frame are respectively rotatably connected to the first slider and the second slider, and the top of the hydraulic push rod is fixedly connected to the bearing plate.

[0014] An installation method for a steam-water pipeline support in a thermal power plant that is convenient for installation includes: Adjust the first main body and the second main body to a height convenient for installing the steam-water pipeline. Then, place the steam-water pipeline on the upper ends of two groups of clamping plates on the first main body. Next, place the second main body on the upper end of the first main body along two groups of threaded rods. Then, sleeved the nuts on the ends of the threaded rods through the grooves, and rotate the nuts to push the second main body along the threaded rods to move towards the first main body to clamp and fix the steam-water pipeline. Since several groups of buffer plates are arranged on the arc-shaped plates on the inner side walls of the clamping plates through positioning grooves, and the buffer plates are in direct contact with the steam-water pipeline. When the steam-water pipeline vibrates during normal operation, since the buffer plates are made of rubber material with buffer and vibration reduction functions, it can play a buffer and vibration reduction effect at this time. When the steam-water pipeline expands, the clamping plates move into the buffer grooves along the limiting plates, making it have a movable range to prevent the steam-water pipeline from being damaged by being squeezed by the pipeline support when it expands. When the steam-water pipeline contracts after expansion, it exerts a thrust on the clamping plates, making the clamping plates closely adhere to the outer wall of the steam-water pipeline, and can continuously provide a supporting force to the steam-water pipeline.

[0015] Compared with the prior art, the present invention has at least the following beneficial technical effects: The present invention provides a steam-water pipeline support for a thermal power plant that is convenient for installation and an installation method. When the steam-water pipeline expands, the clamping plates move into the buffer grooves along the limiting plates through the limiting grooves, making it have a movable range to prevent the steam-water pipeline from being damaged by being squeezed by the pipeline support when it expands. When the steam-water pipeline contracts after expansion, since the return spring continuously exerts a thrust on the clamping plates through the telescopic rods, the clamping plates closely adhere to the outer wall of the steam-water pipeline, and can continuously provide a supporting force to the steam-water pipeline. That is, the pipeline support can effectively cope with the expansion and contraction states generated when the steam-water pipeline is in normal operation, effectively avoiding the steam-water pipeline from being damaged by being squeezed by the pipeline support when it expands and when the steam-water pipeline contracts after expansion, since the return spring continuously exerts a thrust on the clamping plates through the telescopic rods, and can continuously provide a supporting force to the steam-water pipeline, ensuring the stability of the steam-water pipeline.

[0016] Start the hydraulic push rod to push the bearing plate to move upward. The motor drives the first slider to move inside the horizontal groove through the rotation of the lead screw. When the first slider moves, it pushes the support frame to rotate. At this time, the support frame pushes the bearing plate to move upward. In order to maintain the smoothness of the up and down movement of the bearing plate, it is necessary to keep the lifting distances of the hydraulic push rod and the support frame consistent. When the bearing plate moves upward, it will push the first main body and the second main body of the steam-water pipeline support to move upward to adjust the height, so as to install steam-water pipelines of different heights.

[0028] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0029] Embodiment 1 Please refer to Figures 1 - 6 , the present invention provides a technical solution: a steam-water pipeline support for a thermal power plant that is easy to install, including a first main body 1 and a second main body 2. Vertical grooves 3 are provided on both side walls of the first main body 1 and the second main body 2. A threaded rod 4 is arranged inside the vertical groove 3. Grooves 5 are provided at the corner positions of the first main body 1 and the second main body 2. Nuts 6 are arranged at both ends of the threaded rod 4 and inside the grooves 5. Buffer grooves 14 are provided inside the first main body 1 and the second main body 2, and a buffer mechanism 7 is arranged inside the buffer groove 14; the buffer mechanism 7 includes four groups of clamping plates 8. An arc-shaped plate 11 is arranged on the inner side wall of the clamping plate 8. A number of positioning grooves 12 are provided on the arc-shaped plate 11, and a buffer plate 13 is clamped inside the positioning groove 12.

[0030] Fixing grooves 10 are provided at the corner positions of the clamping plate 8, and a telescopic rod 15 is arranged between the inner side wall of the fixing groove 10 and the inner side wall of the buffer groove 14.

[0031] A return spring 16 is wound around the middle position of the telescopic rod 15. Limiting grooves 9 are provided on both side walls of the clamping plate 8, and limiting plates 17 are provided on both inner side walls of the buffer groove 14.

[0032] The top of the buffer plate 13 is arranged in a T shape. A number of buffer plates 13 are arranged on the inner side wall of the arc-shaped plate 11 through the positioning grooves 12. The buffer plate 13 is made of rubber material. The clamping plate 8 is movably arranged inside the buffer groove 14 along the limiting groove 9 through the cooperation of the telescopic rod 15 and the return spring 16 with the limiting plate 17.

[0033] During use, the staff adjusts the first main body 1 and the second main body 2 to a height convenient for installing the steam-water pipeline through the lifting mechanism 18. Then, the steam-water pipeline is placed on the upper ends of the two groups of clamping plates 8 on the first main body 1. Next, the second main body 2 is placed on the upper end of the first main body 1 along the two groups of threaded rods 4. Then, the nut 6 is sleeved on the end of the threaded rod 4 through the groove 5, and the nut 6 is rotated to push the second main body 2 towards the first main body 1 along the threaded rod 4 to clamp and fix the steam-water pipeline. Through the above operations, the installation of this steam-water pipeline support is relatively simple and convenient for the staff to install; since a number of buffer plates 13 are arranged on the arc-shaped plate 11 on the inner side wall of the clamping plate 8 through the positioning grooves 12, and the buffer plates 13 are in direct contact with the steam-water pipeline. When the steam-water pipeline vibrates during normal operation, since the buffer plates 13 are made of rubber material with a buffer and vibration reduction effect, it can play an effective buffer and vibration reduction effect at this time, improving the stability of the steam-water pipeline during normal operation. When the steam-water pipeline expands, the clamping plate 8 moves into the buffer groove 14 along the limiting plate 17 through the limiting groove 9, giving it a movable range to prevent the steam-water pipeline from being damaged by being squeezed by the pipeline support when it expands. When the steam-water pipeline contracts after expansion, since the return spring 16 continuously exerts a thrust on the clamping plate 8 through the telescopic rod 15, the clamping plate 8 is closely attached to the outer wall of the steam-water pipeline, and can always provide a supporting force to the steam-water pipeline. That is, this pipeline support can effectively cope with the expansion and contraction states generated during the normal operation of the steam-water pipeline, effectively avoiding the damage of the steam-water pipeline being squeezed by the pipeline support when it expands, and when the steam-water pipeline contracts after expansion, since the return spring 16 continuously exerts a thrust on the clamping plate 8 through the telescopic rod 15, it can always provide a supporting force to the steam-water pipeline, ensuring the stability of the steam-water pipeline.

[0034] Embodiment 2 Please refer to Figures 1 - 6 , the present invention provides a technical solution: a steam-water pipeline support for a thermal power plant that is easy to install, including a first main body 1 and a second main body 2. Vertical grooves 3 are opened on both side walls of the first main body 1 and the second main body 2. Threaded rods 4 are arranged inside the vertical grooves 3. Grooves 5 are opened at the corner positions of the first main body 1 and the second main body 2. Nuts 6 are arranged at both ends of the threaded rod 4 and inside the grooves 5. Buffer grooves 14 are opened inside the first main body 1 and the second main body 2. A buffer mechanism 7 is arranged inside the buffer grooves 14; the buffer mechanism 7 includes four groups of clamping plates 8. An arc-shaped plate 11 is arranged on the inner side wall of the clamping plate 8. A number of positioning grooves 12 are opened on the arc-shaped plate 11. Buffer plates 13 are clamped inside the positioning grooves 12.

[0035] A lifting mechanism 18 is arranged at the bottom of the first main body 1. The lifting mechanism 18 includes a base 19 and a bearing plate 20. Two groups of transverse grooves 21 are opened on the surfaces of the base 19 and the bearing plate 20. Lead screws 22 are arranged inside the transverse grooves 21.

[0036] A first slider 23 is arranged on the lead screw 22 and inside the transverse groove 21, and second sliders 24 are arranged at the corner positions on the base 19 and the bearing plate 20. A support frame 25 is arranged between the first slider 23 and the second slider 24, and a hydraulic push rod 26 is arranged at the upper end of the base 19.

[0037] The upper end of the bearing plate 20 is fixedly connected to the bottom end of the first main body 1. A motor connected to the end of the lead screw 22 is arranged inside the base 19. The first slider 23 is slidably arranged inside the base 19 along the transverse groove 21 by the cooperation of the motor and the lead screw 22.

[0038] The support frame 25 is arranged in a rotatable X shape. The end parts of the support frame 25 are respectively rotatably connected to the first slider 23 and the second slider 24. The top of the hydraulic push rod 26 is fixedly connected to the bearing plate 20.

[0039] Specifically, when the hydraulic push rod 26 is started to push the bearing plate 20 to move upward, the motor drives the first slider 23 to move inside the transverse groove 21 through the rotation of the lead screw 22. When the first slider 23 moves, it pushes the support frame 25 to rotate. At this time, the support frame 25 pushes the bearing plate 20 to move upward. In order to keep the smoothness of the up and down movement of the bearing plate 20, it is necessary to keep the lifting distances of the hydraulic push rod 26 and the support frame 25 consistent. When the bearing plate 20 moves upward, it will push the first main body 1 and the second main body 2 to move upward, so as to install the steam-water pipes at different heights.

[0040] Working principle: The staff adjusts the first main body 1 and the second main body 2 to a height convenient for installing the steam-water pipeline through the lifting mechanism 18, starts the hydraulic push rod 26 to push the bearing plate 20 to move upward, and the motor drives the first slider 23 to move inside the transverse groove 21 by rotating the lead screw 22. When the first slider 23 moves, it pushes the support frame 25 to rotate. At this time, the support frame 25 pushes the bearing plate 20 to move upward. In order to maintain the smoothness of the up and down movement of the bearing plate 20, it is necessary to keep the lifting distances of the hydraulic push rod 26 and the support frame 25 consistent. When the bearing plate 20 moves upward, it will push the first main body 1 and the second main body 2 to move upward, so that the steam-water pipeline of different heights can be installed. Then, the steam-water pipeline is placed on the upper ends of the two groups of clamping plates 8 on the first main body 1, and the second main body 2 is placed on the upper end of the first main body 1 along the two groups of threaded rods 4. Then, the nut 6 is sleeved on the end of the threaded rod 4 through the groove 5, and the nut 6 is rotated to push the second main body 2 to move towards the first main body 1 along the threaded rod 4 to clamp and fix the steam-water pipeline. Through the above operations, the installation of the steam-water pipeline support is relatively simple and convenient for the staff to install; since a number of buffer plates 13 are arranged on the arc-shaped plate 11 on the inner side wall of the clamping plate 8 through the positioning groove 12, and the buffer plates 13 are in direct contact with the steam-water pipeline. When the steam-water pipeline vibrates during normal operation, since the buffer plates 13 are made of rubber material with buffer and vibration reduction functions, they can play an effective buffer and vibration reduction effect at this time, improving the stability of the steam-water pipeline during normal operation. When the steam-water pipeline expands, the clamping plate 8 moves into the buffer groove 14 along the limiting plate 17 through the limiting groove 9, making it have a movable range to prevent the steam-water pipeline from being damaged by being squeezed by the pipeline support when it expands. When the steam-water pipeline contracts after expansion, since the return spring 16 continuously applies a thrust to the clamping plate 8 through the telescopic rod 15, the clamping plate 8 is closely attached to the outer wall of the steam-water pipeline, and can always provide a supporting force to the steam-water pipeline. That is, the pipeline support can effectively cope with the expansion and contraction states generated during the normal operation of the steam-water pipeline, effectively avoiding the damage of the steam-water pipeline being squeezed by the pipeline support when it expands and the return spring 16 continuously applying a thrust to the clamping plate 8 through the telescopic rod 15 when the steam-water pipeline contracts after expansion, and can always provide a supporting force to the steam-water pipeline, ensuring the stability of the steam-water pipeline.

[0041] Embodiment 3 An installation method of a steam-water pipeline support for a thermal power plant that is convenient for installation provided by the present invention includes: Adjust the first main body 1 and the second main body 2 to a height convenient for installing the steam-water pipeline. Then, place the steam-water pipeline on the upper ends of two sets of clamping plates 8 on the first main body 1. Next, place the second main body 2 on the upper end of the first main body 1 along two sets of threaded rods 4. Then, sleuth the nut 6 on the end of the threaded rod 4 through the groove 5, and rotate the nut 6 to push the second main body 2 towards the first main body 1 along the threaded rod 4 to clamp and fix the steam-water pipeline. Since a number of buffer plates 13 are arranged on the arc-shaped plate 11 on the inner side wall of the clamping plate 8 through the positioning groove 12, and the buffer plates 13 are in direct contact with the steam-water pipeline. When the steam-water pipeline vibrates during normal operation, since the buffer plates 13 are made of rubber material with buffer and vibration reduction functions, they can play a buffer and vibration reduction effect at this time. When the steam-water pipeline expands, the clamping plate 8 moves into the buffer groove 14, giving it a movable range to prevent the steam-water pipeline from being damaged by being squeezed by the pipeline support when it expands. When the steam-water pipeline contracts after expansion, a thrust is applied to the clamping plate 8, making the clamping plate 8 closely adhere to the outer wall of the steam-water pipeline, and it can always provide a supporting force to the steam-water pipeline.

A method for installing a steam-water pipe support for a thermal power plant that is easy to install according to any one of claims 1 to 9, characterized in that: include: The first body (1) and the second body (2) are adjusted to a height convenient for installing the steam-water pipe, and then the steam-water pipe is placed on the upper end of the two groups of clamping plates (8) on the first body (1), and then the second body (2) is placed on the upper end of the first body (1) along the two groups of threaded rods (4), and then the nut (6) is sleeved on the end of the threaded rod (4) through the groove (5), and the nut (6) is rotated along the threaded rod (4) to push the second body (2) toward the position of the first body (1), so as to clamp and fix the steam-water pipe; since the arc plate (11) on the inner side wall of the clamping plate (8) is provided with a positioning groove (12), A plurality of groups of buffer plates (13) are provided, wherein the buffer plates (13) are in direct contact with the steam-water pipe. When the steam-water pipe vibrates during normal operation, the buffer plates (13) are made of a rubber material having a buffering and vibration-reducing effect, so that they can play a buffering and vibration-reducing effect at this time. When the steam-water pipe expands, the clamping plate (8) moves into the buffer groove (14) so ​​that it has a movable range, thereby preventing the steam-water pipe from being squeezed and damaged by the pipe support when it expands. When the steam-water pipe contracts after expansion, a thrust is applied to the clamping plate (8), so that the clamping plate (8) is closely attached to the outer wall of the steam-water pipe, thereby being able to provide support force to the steam-water pipe all the time.
