Description

Technical Field

[0001] This application relates to the field of high-pressure pipe fitting testing technology, and in particular to a high-pressure pipe testing device and testing method. Background Technology

[0002] In related technologies, pressure testing of high-pressure inner tubes usually relies on fixed testing devices, which are mostly single-function frame platforms with a lack of flexible modular design, resulting in difficulties in equipment handling and installation.

[0003] During pipe fitting testing, positioning deviations are prone to occur during clamping, making it difficult to guarantee the accuracy of the sealing fit and resulting in low work efficiency. During the filling of the test medium, residual gas or insufficient medium filling may occur inside the pipe fitting, thus affecting the accuracy of the pressure test results. Summary of the Invention

[0004] This application provides a high-pressure pipe testing device and testing method to solve the problems of fixed structure, low modularity, inconvenient installation, and poor sealing of high-pressure pipe testing devices.

[0005] The high-pressure pipe testing equipment and method provided in this application improve the installation efficiency of high-pressure pipes and enhance the sealing performance of high-pressure pipe tests by movably setting the first end of the mounting bracket on the main body and sealing the opening of the high-pressure pipe with a sealing component.

[0006] In a first aspect, embodiments of this application provide a high-pressure pipe testing device, including a main body, a mounting bracket, and a sealing element; the mounting bracket is used to install the high-pressure pipe to be tested; a first end of the mounting bracket is movably disposed on the main body, and a second end of the mounting bracket is configured to correspond to the opening of the high-pressure pipe.

[0007] When the mounting bracket is in the filling state, the second end of the mounting bracket is away from the main body, providing sufficient operating space for the filling of the test liquid. The sealing element is used to close at least the opening of the high-pressure pipe; this facilitates the sealing operation of the high-pressure pipe and helps to improve the installation efficiency of the high-pressure pipe.

[0008] When the mounting bracket is in the test state, the second end of the mounting bracket is close to the main body. The sealing element can be used to pressurize the high-pressure pipe. The sealing element is used to form a stable and reliable closed pressurization structure for the high-pressure pipe, ensuring tight sealing and uniform force during pressurization, and improving the sealing reliability and test safety of the high-pressure pipe during testing.

[0009] In one possible implementation, the mounting bracket includes a fixed component and a movable component; the fixed component is movably connected to the main body. This provides operational space for sealing the high-pressure pipe during assembly, improving assembly flexibility and maintenance convenience.

[0010] The movable component is detachably mounted on the fixed component, and the fixed component can be connected to the high-pressure pipe through the movable component; this facilitates the replacement or adjustment of the movable component according to the specifications, quantity, and layout requirements of the high-pressure pipe.

[0011] The fixing component can connect to and position the high-pressure pipe through the movable component, so as to reliably fix, limit and support the high-pressure pipe through the movable component, and avoid the high-pressure pipe from shaking or wearing during equipment operation.

[0012] By setting the mounting bracket as a combination of fixed and movable parts, on the one hand, the movable connection between the fixed parts and the main body enables the overall posture to be adjustable, meeting the pipeline layout requirements under different assembly scenarios; on the other hand, the detachable structure of the movable parts enables the adaptation and fixing of high-pressure pipes, improving the versatility and stability of pipeline installation, while simplifying the assembly process, reducing assembly difficulty, and helping to improve production efficiency and extend the service life of high-pressure pipes.

[0013] In one possible implementation, the fixing member is rotatably mounted on the main body, allowing the fixing member to rotate, swing, or flip relative to the main body, thereby enabling flexible adjustment of the installation angle and assembly position. This facilitates ensuring that the sealing surfaces between the high-pressure pipe and the sealing member can fully and evenly fit together when clamping the high-pressure pipe, providing a basic condition for achieving a reliable seal.

[0014] The movable component is equipped with a limiting structure and a locking structure; the limiting structure abuts against the movable component. By constraining and adjusting the assembly position of the movable component through the limiting structure, the installation posture and assembly position of the high-pressure pipe can be precisely limited, ensuring that the high-pressure pipe remains accurately positioned and stable in posture during clamping, ensuring reliable clamping, and preventing the high-pressure pipe from shifting, tilting, or loosening during assembly or operation.

[0015] The locking structure connects the movable part to the fixed part, and locks and fixes the movable part, further ensuring that the high-pressure pipe is firmly clamped and preventing displacement of the high-pressure pipe due to vibration during equipment operation, thereby continuously ensuring the stability of equipment operation.

[0016] In one possible implementation, the limiting structure includes a bracket and an adjusting bolt; the bracket is fixedly mounted on the fixing member to provide stable installation support and a force-bearing foundation for the adjusting bolt.

[0017] The adjusting bolt is threadedly connected to the bracket. By rotating the adjusting bolt, its extension length can be changed, so that the end of the adjusting bolt can reliably abut against the movable part, and the position of the movable part can be finely adjusted and positioned to achieve precise adjustment of the high-pressure pipe installation position, ensuring accurate and reliable clamping of the high-pressure pipe.

[0018] Optionally, the locking structure is configured as a locking bolt, which passes through the fixed member and is threadedly connected to the movable member. By tightening the locking bolt, a tight connection and locking fixation can be achieved between the fixed member and the movable member, preventing the movable member from loosening or shifting under external force, and further improving the stability and sealing of the high-pressure pipe clamping.

[0019] In one possible implementation, the movable component includes a first pressing part and a second pressing part that are movably connected; the first pressing part and the second pressing part can open and close relative to each other, thereby forming a clamping and releasing space for the high-pressure pipe, which facilitates the disassembly, positioning and replacement of the high-pressure pipe.

[0020] When the movable part is in the first state, the first pressing part and the second pressing part approach each other to clamp and fix the high-pressure pipe. This forms a circumferential wrap and radial compression around the high-pressure pipe, ensuring that the high-pressure pipe is stable in position, does not shake, and does not shift during assembly and operation, improving clamping reliability, and providing a stable clamping foundation for the high-pressure pipe sealing.

[0021] When the movable part is in the second state, the first pressing part and the second pressing part move away from each other to release the high-pressure pipe. This facilitates the smooth insertion of the high-pressure pipe into the clamping area or its removal from the movable part, simplifying the assembly and disassembly of the high-pressure pipe and improving maintenance convenience and assembly efficiency.

[0022] In one possible implementation, the first pressing part is provided with a first receiving groove, and the second pressing part is provided with a second receiving groove, with the first receiving groove and the second receiving groove being arranged opposite to each other. Together, they enclose a clamping space for accommodating the high-pressure pipe. The inner walls of the first and second receiving grooves can be adapted to the outer wall of the high-pressure pipe, increasing the contact area with the high-pressure pipe, so that the high-pressure pipe is stably clamped and avoiding local stress concentration that could cause pipeline damage.

[0023] A connecting part is provided between the first pressing part and the second pressing part, and the first pressing part and the second pressing part can be relatively fixed and pre-tightened through the connecting part.

[0024] After the high-pressure pipe is placed between the first and second receiving grooves, the first and second pressing parts are fixed by the connecting part, so that the two are kept in a closed state, thereby forming a continuous and stable clamping force on the high-pressure pipe, ensuring that the high-pressure pipe does not loosen, deviate, or move during operation, and improving the clamping reliability and sealing stability.

[0025] In one possible implementation, the main body includes a base plate and a support frame; the bottom end of the support frame is connected to the base plate, and the top end of the support frame extends along the height direction; forming a support structure with a certain support height, which facilitates providing support, limiting and guiding the movement of the mounting frame, making reasonable use of the space in the height direction, and making the overall layout more compact.

[0026] When the mounting bracket is in the filling state, the second end of the mounting bracket is close to the top of the support frame, and the extension direction of the mounting bracket is parallel to the height direction; this keeps the mounting bracket in a vertical position during the filling process, which facilitates the positioning and sealing of the high-pressure pipe in the vertical direction, ensures the stability of the pipeline position during the filling process, and helps to improve the filling accuracy and sealing effect.

[0027] Optionally, a drive device is also included, which is disposed on the main body. The output end of the drive device is connected to the mounting frame in a transmission manner. The drive device is at least used to drive the mounting frame to move relative to the main body. This enables the mounting frame to switch between different work positions and different states, improves the automation level of the device, reduces manual operation, and improves assembly and pouring efficiency.

[0028] In one possible implementation, the seal includes a first connecting portion, a second connecting portion, and a pressure testing structure; the first connecting portion is used to connect with the high-pressure pipe, providing a reliable sealing base for the high-pressure pipe and ensuring that there is no media leakage during the filling and operation of the high-pressure pipe.

[0029] The second connecting part is spaced apart from the first connecting part and is used to fix and cooperate with the first connecting part to form a stable and tight pipeline sealing structure.

[0030] The pressure testing structure is located between the first connecting part and the second connecting part. It can seal the port of the high-pressure pipe by means of the clamping action of the first connecting part and the second connecting part, so that the high-pressure pipe forms a closed pressurized cavity during the pressure testing or injection stage.

[0031] The pressure testing structure has a pressure testing channel inside, which is connected to the internal space of the high-pressure pipe. The pressure testing medium can be introduced into the high-pressure pipe through the pressure testing channel, which can be used to pressurize the high-pressure pipe to achieve pressure testing of the high-pressure pipe.

[0032] With the combination of the above structures, the sealing element can not only achieve the fixed sealing and connection of the high-pressure pipe, but also integrate the pressure testing function at the same time. There is no need to set up an additional independent pressure testing interface structure, which simplifies the overall structural layout of the device and improves the space utilization rate.

[0033] Meanwhile, the pressure testing channel allows for direct pressure testing of the high-pressure pipe under sealed connection conditions, quickly verifying the sealing performance, welding quality, and pipeline integrity of the high-pressure pipe. This effectively improves the efficiency and reliability of the pressure testing, ensuring the safe operation of the grouting process.

[0034] Secondly, embodiments of this application provide a high-voltage pipe testing method, applied to the high-voltage pipe testing equipment described in any of the above possible embodiments, the testing method comprising:

[0035] The mounting bracket is in the assembly state, with its second end close to the main body; the high-pressure pipe is installed on the mounting bracket so that the opening of the high-pressure pipe corresponds to the second end of the mounting bracket; this enables rapid and centered installation of the high-pressure pipe, improving assembly efficiency and positioning accuracy.

[0036] The mounting bracket is controlled to be in a filling state, with the second end of the mounting bracket away from the main body; test liquid is poured into the high-pressure pipe through the opening of the high-pressure pipe, and the opening of the high-pressure pipe is sealed by a sealing element; the liquid injection and sealing are completed in a space away from the main body, which facilitates operation and avoids test liquid overflow, and the sealing element provides a reliable sealing basis for subsequent pressurization operations.

[0037] The mounting bracket is controlled to be in a test state, with the second end of the mounting bracket close to the main body; pressure is applied to the high-pressure pipe through the sealing element to test the high-pressure pipe; the high-pressure pipe is reset to a stable test state, relying on the main body and the mounting bracket to provide rigid support, avoiding pipe shaking or displacement during pressurization, and improving the accuracy, repeatability and operational safety of test results.

[0038] In one possible implementation, the mounting bracket includes a fixed member and a movable member; mounting the high-pressure pipe to the mounting bracket includes:

[0039] Based on the specifications such as the outer diameter of the high-pressure pipe and the pipe shape, a movable component of a set specification is determined. The movable component includes a first pressing part and a second pressing part that are movably connected. By setting replaceable movable components, this application enables the mounting bracket to be adapted to high-pressure pipes of various specifications, improves the versatility of the high-pressure pipe testing equipment, and significantly reduces the testing cost.

[0040] The first pressing part is installed on the fixing member through the limiting structure and the locking structure. The high-pressure pipe is placed on the first pressing part, and the second pressing part is connected to the first pressing part, so as to clamp and fix the high-pressure pipe through the first pressing part and the second pressing part.

[0041] By utilizing the limiting and locking mechanism of the first pressing part and the fixing part, as well as the enveloping clamping of the pipeline by the upper and lower pressing parts, the stability of the high-pressure pipeline during the injection and pressurization stages is ensured. The entire installation process does not require complicated debugging tools and can quickly complete the clamping of the pipeline, significantly shortening the preparation time of a single pipeline and improving the overall work efficiency of the testing process.

[0042] The high-pressure pipe testing equipment provided in this application embodiment has a mounting bracket whose first end is movably mounted on the main body. By moving the mounting bracket, the two states of filling and testing can be switched. The overall layout is compact, enabling rapid and centered installation of the high-pressure pipe, improving assembly efficiency and positioning accuracy. The use of sealing components to pressurize and seal the opening of the high-pressure pipe further enhances installation efficiency and improves the sealing performance of the high-pressure pipe during testing.

[0043] When the mounting bracket is in the filling state, the second end of the mounting bracket is away from the main body, providing ample operating space for the filling of the test liquid. The seal is used to close at least the opening of the high-pressure pipe; this facilitates the sealing operation of the high-pressure pipe and helps improve the installation efficiency of the high-pressure pipe.

[0044] When the mounting bracket is in the testing state, the second end of the mounting bracket is close to the main body. The seal can be used to pressurize the high-pressure pipe. The seal is used to form a stable and reliable closed pressurization structure for the high-pressure pipe, ensuring tight sealing and uniform force during pressurization, and improving the sealing reliability and testing safety of the high-pressure pipe.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0064] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application.

[0065] Figure 1 This application provides a schematic diagram of a high-pressure pipe testing scenario. Figure 1 , Figure 2 This application provides a schematic diagram of a high-pressure pipe testing scenario. Figure 2 ,like Figure 1 , Figure 2 As shown, this application is specifically applied to the testing process of high-pressure pipes. In related technologies, pressure testing of high-pressure inner pipes usually relies on fixed testing devices, whose structures are mostly single-function frame platforms, lacking flexible modular design, resulting in difficulties in equipment transportation and installation, and inconvenience in on-site layout and commissioning.

[0066] During pipe fitting testing, positioning deviations are prone to occur during clamping, making it difficult to guarantee the accuracy of the sealing fit and resulting in low work efficiency. During the filling of the test liquid, residual gas or insufficient medium filling may occur inside the pipe fitting, thus affecting the accuracy of the pressure test results.

[0067] The high-pressure pipe testing equipment is located within pit 10, which is designed to be square or oblong and constructed of heavy-duty reinforced concrete, providing strong load-bearing capacity. Cameras 900 are installed within pit 10 and near the high-pressure pipe testing equipment to monitor the entire high-pressure pipe pressure test process, focusing on the seals 400 at both ends of the high-pressure pipe 500, pressure gauges 520, and pressure sensors 540. A remote monitoring control room 800 is located in a separate area at the edge of pit 10, equipped with an isolation wall 700 for protective isolation, enabling remote operation and full-process monitoring of the high-pressure pipe pressure test.

[0068] By movably setting the first end of the mounting bracket 20 of the high-pressure pipe testing equipment to the main body 100 and using the sealing component 400 to seal and pressurize the opening of the high-pressure pipe 500, the installation efficiency of the high-pressure pipe is improved and the sealing performance during the high-pressure pipe testing process is enhanced.

These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can be a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0073] In a first aspect, embodiments of this application provide a high-pressure pipe testing device, including a main body 100, a mounting bracket 20, and a sealing element 400; the mounting bracket 20 is used to install the high-pressure pipe 500 to be tested; the first end of the mounting bracket 20 is movably disposed on the main body 100, and the second end of the mounting bracket 20 is used to correspond to the opening of the high-pressure pipe 500.

[0074] When the mounting bracket 20 is in the filling state, the second end of the mounting bracket 20 is away from the main body 100, providing sufficient operating space for the filling of the test liquid. The seal 400 is used to close the opening of the high-pressure pipe 500; it facilitates the sealing operation of the high-pressure pipe 500 and helps to improve the installation efficiency of the high-pressure pipe 500.

[0075] When the mounting bracket 20 is in the test state, the second end of the mounting bracket 20 is close to the main body 100. The seal 400 can be used to pressurize the high-pressure pipe 500. The seal 400 is used to form a stable and reliable closed pressurization structure for the high-pressure pipe 500, ensuring tight sealing and uniform force during pressurization, and improving the sealing reliability and test safety of the high-pressure pipe 500 during testing.

[0076] In one possible implementation, the mounting bracket 20 includes a fixed member 200 and a movable member 300; the fixed member 200 is movably connected to the main body 100. This provides operational space for sealing the high-pressure pipe 500 during assembly, improving assembly flexibility and maintenance convenience.

[0077] The movable part 300 is detachably mounted on the fixed part 200, and the fixed part 200 can be connected to the high-pressure pipe 500 through the movable part 300; this facilitates the replacement or adjustment of the movable part 300 according to the specifications, quantity and layout requirements of the high-pressure pipe 500.

[0078] The fixed component 200 can be connected to and positioned by the movable component 300, so as to reliably fix, limit and support the high-pressure pipe 500 through the movable component 300, and prevent the high-pressure pipe 500 from shaking or wearing during equipment operation.

[0079] By setting the mounting bracket 20 as a combination structure of fixed part 200 and movable part 300, the overall posture can be adjusted by utilizing the movable connection between the fixed part 200 and the main body 100, so as to meet the pipeline layout requirements under different assembly scenarios.

[0080] On the other hand, the detachable structure of the movable part 300 is used to adapt and fix the high-pressure pipe 500, which improves the versatility and stability of pipeline installation, simplifies the assembly process, reduces assembly difficulty, and helps to improve production efficiency and extend the service life of the high-pressure pipe 500.

[0081] In one possible implementation, the fixing member 200 is rotatably disposed on the main body 100, so that the fixing member 200 can rotate, swing or flip relative to the main body 100, thereby realizing flexible adjustment of the installation angle and assembly position. This facilitates ensuring that the sealing surface between the high pressure pipe 500 and the sealing member 400 can be fully and evenly fitted when clamping the high pressure pipe 500, providing a basic condition for achieving a reliable seal.

[0082] The movable part 300 is provided with a limiting structure 210 and a locking structure 220; the limiting structure 210 abuts against the movable part 300.

[0083] By constraining and adjusting the assembly position of the movable part 300 through the limiting structure 210, the installation posture and assembly position of the high-pressure pipe 500 can be precisely limited, so that the high-pressure pipe 500 maintains accurate positioning and stable posture during the clamping process, ensuring reliable clamping and preventing the high-pressure pipe 500 from shifting, tilting or loosening during assembly or operation.

[0084] The locking structure 220 can connect the movable part 300 to the fixed part 200. By locking the movable part 300 through the locking structure 220, the high-pressure pipe 500 is further secured, preventing displacement of the high-pressure pipe 500 due to vibration during equipment operation, thereby continuously ensuring the stability of equipment operation.

[0085] Please refer to Figure 8 In one possible implementation, the limiting structure 210 includes a bracket 211 and an adjusting bolt 212; the bracket 211 is disposed on the fixing member 200 and is used to provide stable installation support and force-bearing foundation for the adjusting bolt 212.

[0086] Optionally, the adjusting bolt 212 is threadedly connected to the bracket 211. By rotating the adjusting bolt 212, its extension length can be changed, so that the end of the adjusting bolt 212 can reliably abut against the movable part 300, and the position of the movable part 300 can be finely adjusted and positioned to achieve precise adjustment of the installation position of the high-pressure pipe 500, ensuring that the high-pressure pipe 500 is clamped accurately and reliably.

[0087] Optionally, the locking structure 220 is configured as a locking bolt, which passes through the fixed part 200 and is threadedly connected to the movable part 300. By tightening the locking bolt, a tight connection and locking fixation can be achieved between the fixed part 200 and the movable part 300, preventing the movable part 300 from loosening or shifting under external force, and further improving the stability and sealing of the high-pressure pipe 500 clamping.

[0088] In one possible implementation, the movable part 300 includes a first pressing part 310 and a second pressing part 320 that are movably connected; the first pressing part 310 and the second pressing part 320 can open and close relative to each other, thereby forming a clamping and releasing space for the high-pressure pipe 500, which facilitates the disassembly, positioning and replacement of the high-pressure pipe 500.

[0089] When the movable part 300 is in the first state, the first pressing part 310 and the second pressing part 320 approach each other to clamp and fix the high-pressure pipe 500. This forms a circumferential wrapping and radial compression of the high-pressure pipe 500, ensuring that the high-pressure pipe 500 is stable in position, does not shake or shift during assembly and operation, improves clamping reliability, and provides a stable clamping foundation for sealing the high-pressure pipe 500.

[0090] When the movable part 300 is in the second state, the first pressing part 310 and the second pressing part 320 move away from each other to release the high-pressure pipe 500. This facilitates the smooth insertion of the high-pressure pipe 500 into the clamping area or its removal from the movable part 300, simplifies the assembly and disassembly of the high-pressure pipe 500, and improves maintenance convenience and assembly efficiency.

[0091] In one possible implementation, such as Figure 8 As shown, the first pressing part 310 is provided with a first receiving groove 311, and the second pressing part 320 is provided with a second receiving groove 321. The first receiving groove 311 and the second receiving groove 321 are arranged opposite to each other. Together, they enclose a clamping space for accommodating the high-pressure pipe 500. The inner walls of the first receiving groove 311 and the second receiving groove 321 can be adapted to the outer wall of the high-pressure pipe 500, increasing the contact area with the high-pressure pipe 500, so that the high-pressure pipe 500 is stably clamped and avoiding local stress concentration that could cause damage to the pipeline.

[0092] Optionally, flexible buffer layers can be provided inside the first receiving groove 311 and the second receiving groove 321 respectively, so as to avoid mechanical damage to the outer surface of the high-pressure pipe 500 caused by hard metal contact while clamping and fixing, and ensure the consistency of the physical state of the pipeline before and after the test.

[0093] A connecting portion 330 is provided between the first pressing portion 310 and the second pressing portion 320, and the first pressing portion 310 and the second pressing portion 320 can be fixed and pre-tightened relative to each other through the connecting portion 330. For example, the connecting portion 330 is fixedly connected by a fastening bolt 331.

[0094] After the high-pressure pipe 500 is placed between the first receiving groove 311 and the second receiving groove 321, the first pressing part 310 and the second pressing part 320 are fixed by the connecting part 330, so that the two are kept in a closed state, thereby forming a continuous and stable clamping force on the high-pressure pipe 500, ensuring that the high-pressure pipe 500 does not loosen, deviate or move during operation, and improving the clamping reliability and sealing stability.

[0095] Please refer to Figure 4 , Figure 5 In one possible implementation, the main body 100 includes a base plate 110 and a support frame 120; the bottom end of the support frame 120 is connected to the base plate 110, and the top end of the support frame 120 extends along the height direction; forming a support structure with a certain support height. Optionally, the support frame 120 is also provided with a diagonal brace 122 to improve the structural stability of the support frame 120.

[0096] This facilitates the provision of support, limiting, and motion guidance for the mounting bracket 20, making reasonable use of space in the height direction and resulting in a more compact overall layout.

[0097] When the mounting bracket 20 is in the pouring state, such as Figure 4 As shown, the second end of the mounting bracket 20 is close to the top of the support bracket 120, and the extension direction of the mounting bracket 20 is parallel to the height direction; this keeps the mounting bracket 20 in a vertical position during the grouting process, which facilitates the positioning and sealing of the high-pressure pipe 500 in the vertical direction, ensures the stability of the pipeline position during the grouting process, and helps to improve the grouting accuracy and sealing effect.

[0098] Optionally, a drive device 130 is also included. The drive device 130 is disposed on the main body 100, and its output end is connected to the mounting frame 20 for transmission. The drive device 130 is used at least to drive the mounting frame 20 to move relative to the main body 100. This enables the mounting frame 20 to switch between different work positions and different states, improves the automation level of the device, reduces manual operation, and improves assembly and pouring efficiency.

[0099] For example, such as Figure 4 , Figure 5 , Figure 6 As shown, the drive device 130 is configured as a hoisting system; the components of the hoisting system, such as the motor reducer, coupling, and wire roller 131, are installed and fixed on the base plate 110 with bolts and nuts.

[0100] Preferably, the motor reducer is positioned in the middle, and two sets of steel wire rollers 131 are respectively arranged on the left and right sides of the inclined support bracket 122 and connected by couplings and drive shafts.

[0101] Optionally, one end of the wire rope 132 is fixed to both sides of the fixing member 200, and after winding through the pulleys set on both sides of the support frame 120, it enters the wire drums on both sides of the hoisting system.

[0102] When it is necessary to switch the mounting bracket 20 to the pouring state, the hoisting system is started. The hoisting system pulls the mounting bracket 20 away from the main body 100, and the support frame 120 keeps the mounting bracket 20 in a vertical state.

[0103] In another possible implementation, the drive unit 130 is configured to switch the state of the crane or trolley lifting the mounting frame 20.

[0104] Furthermore, a locking buckle 121 is provided on the support frame 120 to fix the mounting bracket 20 and ensure that the mounting bracket 20 remains stable.

[0105] Please refer to Figure 7 In one possible implementation, the seal 400 includes a first connecting portion 410, a second connecting portion 420, and a pressure testing structure 430; the first connecting portion 410 is used to connect to the high-pressure pipe 500, providing a reliable sealing base for the high-pressure pipe 500 and ensuring that the high-pressure pipe 500 has no media leakage during filling and operation.

[0106] The second connecting part 420 is spaced apart from the first connecting part 410 and is used to fix and cooperate with the first connecting part 410 to form a stable and tight pipeline sealing structure.

[0107] The pressure testing structure 430 is disposed between the first connecting part 410 and the second connecting part 420. It can close the port of the high-pressure pipe 500 by means of the clamping action of the first connecting part 410 and the second connecting part 420, so that the high-pressure pipe 500 forms a closed pressurized cavity during the pressure testing or injection stage.

[0108] The pressure testing structure 430 has a pressure testing channel 431 inside, which is connected to the internal space of the high-pressure pipe 500. The pressure testing medium can be introduced into the high-pressure pipe 500 through the pressure testing channel 431. The pressure testing channel 431 can be used to pressurize the high-pressure pipe 500 to realize the pressure detection of the high-pressure pipe 500.

[0109] With the cooperation of the above structures, the seal 400 can not only achieve the fixed sealing and connection of the high-pressure pipe 500, but also integrate the pressure testing function at the same time. There is no need to set up an additional independent pressure testing interface structure, which simplifies the overall structural layout of the device and improves the space utilization.

[0110] Meanwhile, the pressure test channel 431 can be used to directly test the high-pressure pipe 500 under sealed connection conditions, quickly verifying the sealing performance, welding quality and pipeline integrity of the high-pressure pipe 500, effectively improving the pressure test efficiency and testing reliability, and providing a guarantee for the safe implementation of the injection process.

[0111] Secondly, this application provides a high-pressure pipe 500 testing method, which is applied to the high-pressure pipe 500 testing equipment in any of the above embodiments. It can complete the entire process of high-pressure pipe 500 assembly positioning, sealing and filling and pressure resistance testing while ensuring testing safety and accuracy. The specific testing method is as follows.

[0112] The control mounting bracket 20 is in the assembly state, and the high-pressure pipe 500 positioning assembly is completed:

[0113] The second end of the mounting bracket 20 is positioned close to the main body 100; the high-pressure pipe 500 to be tested is stably installed in the preset assembly position of the mounting bracket 20 so that the opening of the high-pressure pipe 500 corresponds to the second end of the mounting bracket 20; this enables the high-pressure pipe 500 to be installed quickly and centered, improving assembly efficiency and positioning accuracy.

[0114] Control mounting bracket 20 to switch to the filling state and perform test liquid filling and port sealing operations:

[0115] The second end of the mounting bracket 20 is controlled to move away from the main body 100 by the drive device 130; the test liquid is pre-filled into the opening of the high-pressure pipe 500 by the injection pump and hose.

[0116] The opening of the high-pressure pipe 500 is sealed by the sealing element 400: the first connecting part 410 is screwed into the threaded end of the high-pressure pipe 500, and the positioning tooling test pressure structure 430, the second connecting part 420, and the connecting element 440 are assembled using a special sealing joint and tightened. Preferably, the test pressure channel 431 at the end of the test pressure structure 430 is temporarily sealed with a plug. Further, a temporary plug is used to temporarily seal the test pressure channel 431.

[0117] In another possible implementation, the first connecting part 410 is configured as a high-pressure threaded flange, the second connecting part 420 is configured as a flange cover, and the connecting piece 440 is configured as a stud and nut connection. The pressure testing and assembly process of the high-pressure pipe 500 in this embodiment includes the following steps:

[0118] Step 1: Screw the high-pressure threaded flange into the end thread of the high-pressure pipe 500 to complete the initial assembly.

[0119] Step 2: Use a plug to temporarily seal the end connection joint of the pressure test structure 430 with handle to prevent the test liquid from flowing out during the assembly process.

[0120] Step 3: Use a special sealing joint to assemble the positioning fixture, and assemble the test pressure structure 430, flange cover, studs and nuts in one go to ensure that all components are coaxially aligned and accurately positioned.

[0121] Step 4: Use a torque wrench to pre-tighten the studs and nuts to create a preliminary clamping fit between the components.

[0122] Step 5: Remove the special sealing joint assembly positioning tooling, and use multiple sets of hydraulic wrenches to simultaneously pre-tighten the high-strength studs and nuts in stages, so that the pre-tightening force is gradually increased to the pre-tightening force range calculated in the design, so as to ensure the reliability and stability of the sealing structure under high pressure conditions.

[0123] The test liquid is filled and sealed in a space away from the main body 100, which facilitates operation and avoids test liquid overflow. The seal 400 provides a reliable sealing basis for subsequent pressurization operations.

[0124] With the control mounting bracket 20 in test mode, a high-voltage test is performed:

[0125] The control mounting bracket 20 is reset from the pouring state to the test state, so that the second end of the mounting bracket 20 is close to the main body 100 again.

[0126] Remove the temporary plug, connect one end of the high-pressure pipe 500 to the pump station system 600 through the high-pressure pipeline 510, and apply test liquid at a set pressure to the high-pressure pipe 500 through the pre-set pressurization channel inside the seal 400 to test the high-pressure pipe 500; maintain the pressure and observe whether there are any abnormalities such as leakage, deformation, or rupture in the high-pressure pipe 500 to complete the pressure resistance and sealing performance test of the high-pressure pipe 500.

[0127] Preferred, such as Figures 1-3 As shown, the other end of the high-pressure pipe 500 is connected to components such as pressure gauge 520, pressure sensor 540 and pressure relief valve 530 for real-time monitoring and system pressure relief.

[0128] The high-pressure pipe 500 is reset to a stable test state, and the main body 100 and the mounting bracket 20 provide rigid support to prevent the pipe from shaking or displacing during pressurization, thereby improving the accuracy, repeatability and safety of the test results.

[0129] For example, the specific control process during the testing of high-pressure pipe testing equipment can be referred to Figure 9 The pressure curve shown indicates that the pump station system 600 is started, and pressure is slowly applied to the high-pressure pipe 500 to the first gradient pressure, and then maintained. Optionally, the first gradient pressure is set to 10% of the test pressure, and the pressure holding time is usually 10 minutes.

[0130] During the process, the content displayed by the 900 camera is monitored simultaneously. After monitoring for any abnormalities or leaks, the inspection personnel can move to the work site of pit 10 for another visual inspection to check for any abnormalities or leaks. Once no abnormalities are found, the personnel will evacuate.

[0131] Once the gradient pressure is reached, the pump station system 600 automatically maintains the pressure. After the experiment reaches point C in the diagram, the next gradient start program has a "continue" button. The system automatically and gradually increases and maintains the pressure in the high-pressure pipe 500 according to the set program curve until the test pressure is reached and the required holding time is achieved.

[0132] After the test pressure holding period is completed, i.e. Figure 9 As shown at point D, the pump station system 600 automatically and slowly depressurizes to the design pressure and then maintains the pressure.

[0133] After the design pressure holding period is completed, that is, when the experiment continues until... Figure 9 After point E, the pump station system 600 automatically performs slow, gradual pressure relief until all pressure in the high-pressure pipe 500 is completely depressurized.

[0134] If any abnormality occurs, the pump station system 600 should be remotely operated and the pressure reduction program should be started to gradually reduce the pressure in stages until all pressure is released. Only then are operators allowed to go to the pit 10 work site to troubleshoot the problem. After the problem is resolved and the personnel have evacuated, the pump station system 600 should be restarted.

[0135] Throughout the entire test, the operators and inspectors monitored the process from the remote monitoring control room, while the remote monitoring system of Camera 900 automatically recorded and saved the video throughout the process.

[0136] If there is no leakage, no abnormal noise, and no abnormal visible deformation during the entire test, the pressure test is deemed qualified; the operators and inspectors shall go to the pit 10 work site again to check and confirm whether there is any leakage of test liquid.

[0137] After the test, the pressure gauge 520, pressure sensor 540, high-pressure pipeline 510, and seal 400 are removed sequentially. The fastening bolts 331, locking structure 220, and adjusting bolts 212 are loosened, and the first pressing part 310 is removed. Non-destructive testing, such as ultrasonic testing and surface magnetic particle or penetrant testing, is performed on the outer surface of the high-pressure pipe 500. The high-pressure pipe 500 is lifted off using a crane or gantry crane, and the next high-pressure pipe 500 is replaced with one undergoing pressure testing and non-destructive testing according to the above procedure. Data is recorded, and a test report is prepared.

[0138] In one possible implementation, the mounting bracket 20 serves as the core load-bearing and positioning component. Its specific structure includes a fixing component 200 and several adaptable and replaceable movable components 300. It is designed to flexibly replace high-pressure pipes 500 of different specifications, so as to achieve universal testing of various product models, improve the versatility of high-pressure pipe 500 testing equipment, and significantly reduce testing costs.

[0139] The high-pressure pipe 500 was installed onto the mounting bracket 20 using a modular rapid assembly process, the specific steps of which are as follows:

[0140] First, based on the specifications such as the outer diameter and shape of the high-pressure pipe 500, the movable component 300 with set specifications is determined. The movable component 300 includes a first pressing part 310 and a second pressing part 320 that are movably connected.

[0141] The first pressing part 310 is detachably mounted to the fixing member 200 via the limiting structure 210 and the locking structure 220. For example, please refer to Figure 8 The limiting structure 210 is configured as a bracket 211 and adjusting bolt 212 to achieve pre-connection of the moving part 300, but not yet tightened. A flexible buffer layer is laid on the first receiving groove 311, and the high-pressure pipe 500 is placed in the first receiving groove 311. During the process, the position of the first pressing part 310 is finely adjusted by adjusting bolt 212 so that the high-pressure pipe 500 is smoothly installed in the designated position. The adjusting bolt 212 and the locking structure 220 are then tightened. After installing the upper half of the flexible buffer layer or wrapping the upper half of the flexible buffer layer around the high-pressure pipe 500, the second pressing part 320 is connected to the first pressing part 310 through the connecting part 330.

[0142] Optionally, the first pressing part 310 and the second pressing part 320 are connected by a connecting part 330 and a fastening bolt, so as to clamp and fix the high-pressure pipe 500 by the first pressing part 310 and the second pressing part 320.

[0143] By utilizing the limiting and locking mechanism between the first pressing part 310 and the fixing member 200, and the enveloping clamping of the pipeline by the first pressing part 310 and the second pressing part 320, the stability of the high-pressure pipe 500 during the filling and pressurization stages is ensured. The entire installation process requires no complex debugging tools, allowing for rapid pipeline clamping, significantly shortening the preparation time for a single pipeline and improving the overall efficiency of the testing process.

[0144] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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 or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
