Description

Technical Field

[0001] The present invention relates to the technical field of cable testing, and in particular to a cable testing device for marine engineering equipment and a testing method thereof. Background Art

[0002] Marine engineering equipment cables play a vital role in the marine environment, and their particularity is mainly reflected in the need to cope with extreme environmental conditions and complex working requirements. The following are the main particularities of marine engineering equipment cables: Seawater contains a large amount of salt, which has a strong corrosive effect on metal materials. Therefore, marine cables usually use corrosion-resistant materials such as stainless steel sheaths, galvanized steel wires, or special coatings to prevent corrosion. Long-term exposure to humid environments requires that the insulation materials of the cables have moisture-proof properties to prevent degradation of the insulation layer or decrease in conductivity. During the installation and operation of marine equipment, the cables may be subjected to greater pulling and tension, so they need to have high tensile strength and elasticity. There may be sharp objects on the seabed or on the surface of the equipment, and the outer sheath of the cable needs to have high wear resistance to prevent surface damage and exposure of the internal conductor.

[0003] Cables must have excellent waterproof properties to prevent seawater intrusion from causing short circuits or conductor corrosion. Multi-layer sealing structures are often used, such as rubber sealing layers, plastic sheaths, etc. In deep-sea environments, cables need to withstand high pressures, and are usually designed with thickened sheaths or pressure-resistant materials to ensure that no structural damage occurs under high pressure. In complex marine environments, cables may be subject to external electromagnetic interference, and shielding layers (such as braided copper wire, aluminum foil, etc.) help reduce electromagnetic interference and improve signal transmission quality. In marine environments, cables may experience large temperature changes, especially in shallow and deep sea areas. Therefore, cable materials need to have good temperature resistance to ensure normal operation at both high and low temperatures. Marine equipment may have frequent movements and vibrations during operation, and cables need to have good flexibility to adapt to the dynamic changes of the equipment to avoid breakage or damage.

[0004] Mechanical testing equipment is used to evaluate the durability and stability of cables under physical stress. It is used to test the tensile strength and ductility of cables to ensure that the cables will not break due to excessive tension during use. It is used to test the wear resistance of cables under friction, scratches, etc., especially in applications that require frequent bending or movement. It tests the durability of cables in repeated bending, simulating the bending and twisting of cables in use. It is used to evaluate the structural stability of cables under torsional forces to ensure that they will not be damaged after multiple twists.

[0005] Existing cable testing equipment is generally used for cables used in normal industrial life. The diameter of such cables is small and can be fixed by clamping. However, the cables used in marine engineering not only have larger diameters, but also use tougher materials, making it more difficult to keep them fixed during the test.

[0006] In view of the above situation, in order to overcome the above technical problems, the present invention designs a marine engineering equipment cable testing device and a testing method thereof, which solves the above technical problems. Summary of the invention

[0007] The technical purpose to be achieved by the present invention is to invent a new marine engineering equipment cable testing device and a testing method thereof, which improves the fixation problem of large cables used in marine engineering equipment during the testing process, ensures the accuracy of the test and improves the success rate of the test.

[0008] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0009] The cable test device for offshore engineering equipment includes multiple components such as a bracket, a test machine, a test tool, a pad, a base and a drive motor. The structure and function of each component are carefully designed to ensure that the equipment can accurately test the performance of the cable under various conditions. The bracket is the basic structure of the test device and is responsible for firmly mounting the entire device on the ground. The material of the bracket is usually high-strength metal to ensure that the equipment does not shift or deform under high load or vibration. The test machine is the core component of the device, which is installed above the bracket to control and perform various test operations. The test tool is installed on the side of the test machine. This is a set of devices for applying stress such as friction, tension, and torsion to the cable. The test tool is usually composed of a variety of tool heads, which can be replaced according to different test requirements, such as wear tools for wear resistance testing, or tension tools for tensile testing. Above the test machine, there is also a pad, whose main function is to provide additional support and buffering. The pad can ensure that the cable is evenly stressed during the test and avoid unnecessary damage to the cable due to the movement of the test machine. The base is installed on both sides of the pad, responsible for bearing the weight of the entire test system and providing a stable installation platform for the drive motor. The drive motor is installed above the base to provide a power source for the test device. The drive motor achieves precise speed and torque output through the control system, and can drive the gear plate and the rotating toothed disc to rotate synchronously. The design of the power system is very critical because it determines the magnitude and stability of the force applied by the test tool to the cable, thereby affecting the accuracy of the test results. In addition, the device also includes a power assembly, a clamping mechanism and a fixing mechanism, which work together to ensure the stability of the cable during the test. The power assembly is installed at the output end of the drive motor to transfer the power of the motor to the gear plate and the rotating toothed disc. The clamping mechanism and the fixing mechanism are respectively installed on the inner side of the base to firmly lock the two ends of the cable in the test position to prevent the cable from moving or loosening during the test.

[0010] The power assembly is composed of a power shaft, a power roller, a mounting groove and a power tooth, and specifically includes the following structures and functions: the power shaft is located at one end of the drive motor and is directly connected to the drive motor to transmit the rotational force output by the motor. The power roller is installed at the other end of the power shaft and is fixedly connected to the power shaft as an intermediate transmission member. There are two mounting grooves, which are evenly distributed on the sides of the power roller. They are annular in shape and can accommodate and fix other components. The design of the mounting groove can not only ensure the stable installation of the power tooth, but also effectively reduce friction and improve transmission efficiency. The power tooth is installed in the mounting groove. As a key part of the transmission chain, it can achieve precise meshing with other mechanical components to ensure efficient transmission and stable operation of the entire power system, thereby improving the overall performance and work efficiency of the mechanical equipment.

[0011] The clamping mechanism consists of a mounting assembly, a clamping assembly and a rotating disk, and has a multi-point clamping function. Specifically, the mounting assembly is fixed to the upper part of the base to provide stable support. The number of clamping assemblies is 3 to 5, evenly distributed on the sides of the mounting assembly, and is used to clamp the objects to be processed or fixed to ensure their stability. The rotating disk is installed on the side of each clamping assembly. By rotating to adjust the opening and closing of the clamping assembly, the clamping force and angle can be adjusted quickly and conveniently, thereby achieving accurate and efficient clamping operations to meet the usage requirements in different scenarios.

[0012] The mounting assembly consists of a mounting plate, mounting holes, mounting blocks, limit blocks and fixing pins, with reasonable structural design and clear functions. The mounting plate is firmly mounted on the upper part of the base to provide basic support for the entire clamping mechanism. The mounting holes are arranged on the side of the mounting plate to facilitate connection and fixation with other components. The number of mounting blocks is consistent with the number of clamping assemblies to ensure that each clamping assembly can be firmly combined with the mounting plate. The limit block is located on the inner side of the mounting block to limit the movement range of the mounting block to prevent it from shifting, thereby ensuring the operating accuracy and safety of the device. The fixing pin is installed above the mounting block to play a locking and fixing role, further enhancing the stability and durability of the mounting assembly and ensuring that the entire device maintains a reliable mechanical connection during operation.

[0013] The clamping assembly consists of a clamping block, a clamping surface, anti-slip stripes, a rotating pin and a rotating sleeve. The clamping block is installed on the side of the mounting assembly. As the core part of the clamping device, it can firmly clamp the cable. The clamping surface is set as the side of the clamping block, and adopts a concave arc surface design to increase the contact area with the object, ensuring more stable and reliable clamping. The clamping surface is covered with anti-slip stripes, which are arranged in a herringbone shape and distributed in a rectangular array, increasing the friction and preventing the object from sliding during the clamping process. The rotating pin is located above the clamping block and is responsible for transmitting the rotational force. By rotating, the clamping block can flexibly adjust its position to adapt to objects of different shapes and sizes. The rotating sleeve is installed on the side of the clamping block and cooperates with the rotating pin to further optimize the flexibility of the clamping block, making the entire clamping operation more precise and efficient, ensuring the safety and stability of the clamped object.

[0014] The rotating disk is composed of a rotating plate, a connecting block, a gear plate and matching holes, and the overall structure is compact and the function is clear. The rotating plate is fixedly mounted on the side of the mounting assembly, serving as the basic component of the rotating disk and supporting the rotation function of the entire structure. The connecting block is mounted on the side of the rotating plate, which plays a role of connection and transmission, firmly connecting the rotating plate and the gear plate together to ensure effective transmission of power. The gear plate is mounted on the side of the connecting block, and is a key component in the entire rotating mechanism, realizing the rotation function through the meshing of gears. The matching holes are evenly distributed on the surface of the gear plate in a circular array, providing an interface for matching with other mechanical components, so that the entire rotating disk can accurately control the rotation angle and position, thereby ensuring the efficiency and reliability of the equipment operation.

[0015] The fixed component consists of four parts: a rotating gear disc, a limiting slide, a fixed disc and a fixed component, and has a precise functional design and a stable structure. The rotating gear disc is installed on the side of the power component and is an important part for realizing mechanical rotation. A limiting slide is provided on its surface to ensure precise control of the rotation process. The limiting slide is opened in an arc shape to meet the rotation requirements of the rotating gear disc and provide a stable motion trajectory to prevent the equipment from offset during operation. The fixed disc is installed on the side of the bottom to provide basic support and fixed position for the entire fixed component. The fixed component is installed inside the fixed disc to ensure the close combination and stable operation of each component. Through this design, the fixed component can effectively lock and adjust the position of the mechanical components, so that the entire system maintains a high degree of stability and reliability during operation, ensuring the normal operation and long-term use of the equipment.

[0016] The fixed plate is composed of three parts: a mounting gasket, a separator block and a positioning slide groove, with precise design and clear functions. The mounting gasket is firmly installed on the side of the base to provide stable support and foundation for the entire fixed plate. The separator block is set on the side of the mounting gasket, and its main function is to form an empty slot area to ensure the accurate installation and functional allocation of the fixed component. Positioning slide grooves are provided at the center axis position of the two sides of the separator block. These slide grooves can accurately cooperate with other mechanical components to ensure the precise positioning and stability of the components. Through this structural design, the fixed plate can effectively adjust and lock the position.

[0017] The fixing assembly is composed of a fixed slider, a sliding pin, a positioning block, a contact surface and a fixing head, and the overall design is used to provide precise fixing and adjustment functions. The fixed slider is installed in the middle position of the fixed disk. As the core component of the fixing assembly, it is responsible for carrying and stabilizing other accessories. The sliding pin is installed on one end of the fixed slider to provide sliding support so that the fixed slider can be moved and adjusted when needed. The positioning block is installed on the side of the fixed slider to help the fixed slider maintain an accurate position on the fixed disk to ensure that it will not shift during operation. The contact surface is set on the fixed slider, away from the side of the sliding pin, which is designed as a contact part, directly in contact with the object to be fixed, to ensure stable clamping. The fixing head is located in the middle of the contact surface and is a vital part of the entire fixing assembly. The fixing head is made of sharp hard material, which can generate efficient fixing force on the contact surface to ensure that the object is firmly clamped and fixed. Such a design enables the fixing assembly to provide reliable support and precise fixing functions in various mechanical operations.

[0018] A method for testing cables of marine engineering equipment, which is used in conjunction with the above-mentioned marine engineering equipment cable testing device; the steps of the method are as follows:

[0019] S1: Cut a sample (50-60cm) from the cable to be tested and ensure that the cable has no prior physical damage or defects.

[0020] S2: Use the clamping mechanism and the fixing mechanism to firmly fix both ends of the cable on the test platform, start the drive motor to clamp the cable, ensure that the cable does not move during the test, and keep the cable in a slightly taut state after being fixed to simulate the tension state in actual use;

[0021] S3: Set the friction frequency (e.g., the number of reciprocating strokes per minute) and friction stroke (the distance the wear tool moves along the cable surface) of the test tool. A force sensor can be used to ensure that the force of each friction remains constant. Set the number of frictions or test time (e.g., 100 reciprocating frictions or continuous testing for 10 minutes).

[0022] S4: Start the test tool and begin to scrape and rub the cable surface. During the test, keep observing to ensure that the contact between the test tool and the cable is uniform and without deviation;

[0023] S5: After the test, stop the test tool and remove the cable sample. Use a microscope or other testing instruments to check the wear on the cable surface, record the degree of scratches or wear (such as cracks, outer skin damage, etc.), measure the change in the outer diameter of the cable, and analyze the impact of wear on the outer diameter.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention improves the problem of fixing large cables used in marine engineering equipment during the test process by setting a clamping mechanism and a fixing mechanism. The position of the cable can be locked during the test process. Locking the position of the cable can prevent the cable from being displaced or twisted during the test process, thereby improving the accuracy and reliability of the test data. The stable cable position can ensure that the test results truly reflect the performance of the cable and avoid errors caused by cable movement. During the test process, if the cable is not properly fixed, it may cause accidental pulling or breaking, thereby causing equipment damage or safety hazards. Effective clamping and fixing can reduce these risks and ensure the safety of operators and equipment. The stable cable fixing method can reduce the adjustment time and complexity during the test process, making the test process more efficient. The frequency of readjustment due to cable displacement is reduced, thereby improving the overall work efficiency. By reducing unnecessary movement of the cable during the test process, the wear of the cable and the test equipment can be reduced, the service life of the equipment can be extended, and the frequency of maintenance and replacement can be reduced. Ensuring that the cable is in the same position in each test helps to improve the repeatability of the test and facilitates reliable comparative analysis and quality control.

[0026] 2. The present invention realizes the fixation and anti-rotation of the cable by setting a power component to drive the clamping mechanism and the fixing mechanism at the same time, optimizes the traditional fixing method, inserts the fixing head into the cable to ensure the fixing strength, and inserts the fixing head into the cable to provide a stronger clamping force to ensure the stability of the cable during the test. This close combination reduces the sliding or movement of the cable during operation and improves the reliability of the fixation. The design of the power component can effectively prevent the cable from rotating or twisting during the test. This helps to maintain the consistency of the test conditions and avoid test data errors caused by cable rotation. By driving the clamping mechanism and the fixing mechanism at the same time, the cable fixing process can be completed more quickly and efficiently. The time for manual adjustment and multiple inspections is reduced, thereby improving the overall work efficiency. The optimized fixing method reduces the friction and wear of the cable during the clamping process and extends the service life of the equipment and cable. The design of the fixing head ensures uniform pressure distribution during the clamping process and reduces the problem of excessive local pressure. Since the cable can maintain the same fixed state in each test, the consistency of the test results is significantly improved. This helps to conduct more accurate comparative analysis and quality control. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] like Figure 1-11As shown, the marine engineering equipment cable test device includes multiple components such as a bracket 1, a test machine 2, a test tool 3, a pad 4, a base 5 and a drive motor 6. The structure and function of each component are carefully designed to ensure that the equipment can perform accurate performance tests on the cable under various conditions. Bracket 1 is the basic structure of the test device, which is responsible for firmly mounting the entire device on the ground. The material of bracket 1 is usually high-strength metal to ensure that the equipment does not shift or deform under high load or vibration. The test machine 2 is the core component of the device, which is installed above the bracket 1 and is used to control and perform various test operations. The test tool 3 is installed on the side of the test machine 2. This is a set of devices for applying stress such as friction, tension, and torsion to the cable. The test tool 3 is usually composed of a variety of tool heads, which can be replaced according to different test requirements, such as a wear tool for wear resistance testing, or a tension tool for tensile testing. Above the test machine 2, there is also a pad 4, whose main function is to provide additional support and buffering. Pad 4 can ensure that the cable is evenly stressed during the test process to avoid unnecessary damage to the cable due to the movement of the test machine 2. The base 5 is installed on both sides of the pad 4, responsible for bearing the weight of the entire test system, and providing a stable installation platform for the drive motor 6. The drive motor 6 is installed above the base 5 to provide a power source for the test device. The drive motor 6 achieves precise speed and torque output through the control system, and can drive the gear plate 833 and the rotating toothed disc 91 to rotate synchronously. The design of the power system is very critical because it determines the size and stability of the force applied by the test tool 3 to the cable, thereby affecting the accuracy of the test results. In addition, the device also includes a power assembly 7, a clamping mechanism 8 and a fixing mechanism 9, which work together to ensure the stability of the cable during the test. The power assembly 7 is installed at the output end of the drive motor 6, and is used to transmit the power of the motor to the gear plate 833 and the rotating toothed disc 91. The clamping mechanism 8 and the fixing mechanism 9 are respectively installed on the inner side of the base 5, and are used to firmly lock the two ends of the cable in the test position to prevent the cable from moving or loosening during the test.

[0043] like Figure 3As shown, the power assembly 7 is composed of a power shaft 71, a power roller 72, a mounting groove 73 and a power tooth 74, and specifically includes the following structures and functions: the power shaft 71 is located at one end of the drive motor 6, and is directly connected to the drive motor 6, and is used to transmit the rotational force output by the motor. The power roller 72 is installed at the other end of the power shaft 71, and is fixedly connected to the power shaft 71, serving as an intermediate transmission member. The mounting grooves 73 are designed to be two and are evenly distributed on the side of the power roller 72. The shape of the mounting grooves 73 is annular and can accommodate and fix other components. The design of the mounting grooves 73 can not only ensure the stable installation of the power teeth 74, but also effectively reduce friction and improve transmission efficiency. The power teeth 74 are installed in the mounting grooves 73. As a key part of the transmission chain, they can achieve precise meshing with other mechanical components to ensure efficient transmission and stable operation of the entire power system, thereby improving the overall performance and work efficiency of the mechanical equipment.

The mounting plate 811 is firmly mounted on the upper part of the base 5 to provide basic support for the entire clamping mechanism 8. The mounting hole 812 is arranged on the side of the mounting plate 811, which is convenient for connection and fixing with other components. The number of mounting blocks 813 is consistent with the number of clamping assemblies 82, ensuring that each clamping assembly 82 can be firmly combined with the mounting plate 811. The limit block 814 is located on the inner side of the mounting block 813, which is used to limit the movement range of the mounting block 813 to prevent it from offset, thereby ensuring the operating accuracy and safety of the device.

[0048] like Figure 8-9As shown, the fixing mechanism 9 is composed of four parts: a rotating toothed disc 91, a limiting slide 92, a fixed disc 93 and a fixed assembly 94, and has a precise functional design and a stable structure. The rotating toothed disc 91 is installed on the side of the power assembly 7, and is an important part for realizing mechanical rotation.

[0049] like Fig.10 As shown, the fixed plate 93 is composed of three parts: a mounting gasket 931, a separator block 932 and a positioning slide groove 933, which are precisely designed and have clear functions. The mounting gasket 931 is firmly mounted on the side of the base 5 to provide a stable support and foundation for the entire fixed plate 93. The separator block 932 is arranged on the side of the mounting gasket 931, and its main function is to form an empty groove area to ensure the accurate installation and function allocation of the fixed component 94.

The contact surface 944 is set on the fixed slider 941, away from the sliding pin 942, and is designed as a contact part, which directly contacts the object to be fixed to ensure stable clamping. The fixing head 945 is located in the middle of the contact surface 944 and is a crucial part of the entire fixing assembly 94. The fixing head 945 is made of a sharp hard material, which can generate an efficient fixing force on the contact surface 944 to ensure that the object is firmly clamped and fixed. Such a design enables the fixing component 94 to provide reliable support and precise fixing functions in various mechanical operations.

[0052] S1: Cut a sample (50-60cm) from the cable to be tested and ensure that the cable has no prior physical damage or defects.

[0053] S2: Use the clamping mechanism 8 and the fixing mechanism 9 to firmly fix both ends of the cable on the test platform, start the drive motor 6 to clamp the cable, ensure that the cable does not move during the test, and keep the cable in a slightly tensioned state after being fixed to simulate the tension state in actual use;

[0054] S3: Set the friction frequency (e.g., the number of reciprocating strokes per minute) and friction stroke (the distance the wear tool moves along the cable surface) of the test tool 3. A force sensor can be used to ensure that the force of each friction remains constant. Set the number of frictions or the test time (e.g., 100 reciprocating frictions or a continuous test of 10 minutes).

[0055] S4: Start the test tool 3 and start to scrape and rub the cable surface. During the test, keep observing to ensure that the contact between the test tool 3 and the cable is uniform and without deviation;

[0056] S5: After the test is completed, stop the test tool 3, remove the cable sample, use a microscope or other testing instruments to check the wear of the cable surface, record the degree of scratches or wear (such as cracks, outer skin damage, etc.), measure the change in the outer diameter of the cable, and analyze the impact of wear on the outer diameter.

[0057] During the working process of the present invention, the staff cuts a 50-60cm long sample from the cable to be tested to ensure that the appearance of the cable has no prior physical damage or defects; uses the clamping mechanism 8 and the fixing mechanism 9 to firmly fix the two ends of the cable on the test platform, starts the driving motor 6 to clamp the cable, and ensures that the cable does not move during the test.

[0058] The driving motor 6 drives the power shaft 71 to rotate, and the power roller 72 rotates, and the power teeth 74 arranged on it respectively drive the clamping mechanism 8 and the fixing mechanism 9 to clamp and fix the cables placed in the middle;

[0059] Part of the clamping mechanism 8: The rotating disk 83 rotates to drive the clamping assembly 82 to rotate under the limit of the mounting assembly 81, so that the clamping surface 822 faces the cable and applies positive pressure to the cable, thereby forming a static friction force between the cable and the anti-slip pattern to resist the rotational force and sliding force generated during the test tool 3 to test the cable; the limit block 814 helps the rotating block to maintain its position during the rotation process;

[0060] Part of the fixing mechanism 9: the rotating toothed disc 91 rotates, and the fixing assembly 94 limited by the partition block 932, because the sliding pin 942 arranged on it is arranged inside the limiting slide groove 92, so that when the rotating toothed disc 91 rotates, the fixed slider 941 slides to the middle of the rotating toothed disc 91, and during this process, the positioning block 943 slides in the positioning slide groove 933 to provide stability, and multiple fixing assemblies 94 approach the cable, and the fixing head 945 arranged on it is vertically inserted into the inside of the cable, thereby further improving the torsion resistance of the cable during the test process, and ensuring the accuracy and success rate of the test;

[0061] Keep the cable in a slightly taut state after fixing to simulate the tension state in actual use; set the friction frequency (such as the number of reciprocating times per minute) and friction stroke of the test tool 3. You can use a force sensor to ensure that the force of each friction remains constant, set the number of frictions or test time; start the test tool 3 and start scraping and rubbing the cable surface. During the test, keep observing to ensure that the contact between the test tool 3 and the cable is uniform and without deviation; after the test, stop the test tool 3, remove the cable sample, use a microscope or other testing instruments to check the wear of the cable surface, record the degree of scratches or wear (such as cracks, outer skin damage, etc.), measure the change in the outer diameter of the cable, and analyze the impact of wear on the outer diameter.
