Description

Technical Field

[0001] The present invention relates to the technical field of elevator equipment detection, and particularly relates to a non-destructive detection device for elevator steel ropes and a detection method thereof. Background Art

[0002] Currently, common elevator steel rope detection methods include visual inspection, electromagnetic inspection, and ultrasonic inspection.

[0003] Visual inspection is the most basic detection method. By observing the surface condition of the steel rope with the naked eye of the inspector, it checks whether there are obvious defects such as broken wires, wear, and corrosion. This method is simple to operate and does not require complex equipment, but it can only detect relatively obvious defects on the surface of the steel rope and cannot detect hidden internal problems, having great limitations. The electromagnetic inspection method applies a magnetic field to the steel rope and analyzes the magnetic field changes to judge the defects of the steel rope. However, this method has high requirements for the detection environment, and surrounding electromagnetic interference may affect the accuracy of the detection results.

[0004] At the same time, oil stains, impurities, etc. on the surface of the steel rope will interfere with the magnetic field signal, resulting in detection errors. Especially when there are metal impurities dropped from other structures during the use of the steel rope, the problem is more prominent.

[0005] The ultrasonic inspection method uses the propagation characteristics of ultrasonic waves in the steel rope to detect internal defects, but this method has high requirements for the surface cleanliness of the steel rope. Surface impurities will interfere with the ultrasonic signal and affect the detection accuracy. In addition, ultrasonic inspection is greatly affected by temperature. In a high-temperature environment, the propagation speed and signal intensity of ultrasonic waves will change. When the steel rope operates for a long time and generates heat due to friction with the conducting parts, the steel rope itself generates a thermal effect, which will also have an adverse impact on the detection, resulting in deviation of the detection results.

[0006] In summary, the existing steel rope detection technologies have certain deficiencies in terms of detection range, environmental adaptability, and detection accuracy, and it is difficult to meet the requirements for comprehensive, efficient, and non-destructive detection of steel ropes. To solve the above problems, it is urgent to develop a device and method that can effectively clean the surface of the steel rope, overcome the detection environment and the temperature of the steel rope itself, and improve the ultrasonic detection accuracy, so as to achieve comprehensive and accurate detection of internal and external defects of elevator steel ropes and ensure the safe operation of elevators.

When rotating, the brush bristles 4011 rotate and contact the side of the steel wire rope 18 to comprehensively clean the surface of the steel wire rope 18.

[0041] III. Impurity treatment structure: Combining Figure 1 , Figure 2 , Figure 4 , a barrier ring member 5 is provided inside the detection tube 3, and a dust reduction chamber 301 is formed between the cleaning component 4 and the barrier ring member 5. A dust blocking conical surface 501 is provided on one side of the barrier ring member 5 facing the dust reduction chamber 301, and a first channel 503 for the steel wire rope 18 to pass through movably is opened at the central position. The dust blocking conical surface 501 can block the dust in the dust reduction chamber 301 from entering the air inlet chamber 302. A waste discharge port 8 located directly below the dust reduction chamber 301 is provided at the bottom of the detection tube 3. A collection tank 9 is assembled at the position of the waste discharge port 8. The collection tank 9 is configured with an electrostatic rod 10 inserted upward into the dust reduction chamber 301. The impurities falling into the dust reduction chamber 301 fall downward into the collection tank 9 under the action of gravity and static electricity.

[0042] IV. Airflow regulation structure: Combining Figure 1 , Figure 5 , an air inlet fan 12 is fixedly installed on the support platform 1. An air inlet filter cartridge 14 is configured at the air inlet end of the air inlet fan 12 for filtering impurities in the outside air. The air outlet end of the air inlet fan 12 is connected to a cooling tube 13. The cooling tube 13 is made of copper pipe and a water-cooled heat exchange module is installed inside. A temperature sensing module is configured at the air inlet end, and the air outlet end is communicated with the air inlet chamber 302 of the detection tube 3. The detection tube 3 is provided with an air inlet 304 located directly below the air inlet chamber 302. The air inlet 304 is connected to the air outlet end of the cooling tube 13 through a sealing gasket. An air flow converging cover 11 is located on the downstream side of the barrier ring member 5, in a horn shape, converging towards the detection chamber 303. A second channel 1101 for the steel wire rope 18 to pass through movably is opened at the central position. Its function is to converge the air flow in the air inlet chamber 302 towards the periphery of the steel wire rope 18, cool the steel wire rope 18, and introduce it into the detection chamber 303.

[0043] V. Detection and exhaust structure: Combining Figure 1 , Figure 3 , Figure 5, an ultrasonic detection module 15 is provided downstream of the air flow converging cover 11 inside the detection tube 3 for detecting the steel wire rope 18. A cover 16 is configured at the outlet end of the detection tube 3. The steel wire rope 18 movably passes through a third channel 1601 opened at the central position of the cover 16. The cover 16 is also provided with a plurality of curved exhaust holes 1602 surrounding the third channel 1601, and the detected air flow is discharged through the curved exhaust holes 1602. When the air flow velocity is low, the curved exhaust holes 1602 can prevent a large amount of external dust from entering the detection chamber 303.

[0044] Embodiment 2. The present invention designs a detection method for an elevator steel wire rope non-destructive detection device, and the specific content is as follows:

[0045] Step 1. Clean the surface of the steel wire rope: Start the drive motor 6, and the rotation of the motor drives the drive gear 7 on the output shaft to rotate. Since the drive gear 7 meshes with the external tooth opening 402 outside the cleaning component 4, the cleaning component 4 is driven to rotate around the bearing ring 403 at the inlet end of the detection tube 3. At this time, the elevator steel wire rope 18 is guided by the guide wheel 17 and horizontally movably passes through the axis position of the detection tube 3. The brush member 401 inside the cleaning component 4 rotates together with the cleaning component 4, and the bristles 4011 inside it make rotational contact with the side of the steel wire rope 18. During this high-speed rotational contact process, the bristles 4011 can effectively strip the oil stains, impurities, etc. attached to the surface of the steel wire rope 18. Some of the impurities generated during the cleaning process, under the action of gravity and the centrifugal force generated by the rotation of the bristles 4011, fall into the dust reduction chamber 301 formed between the cleaning component 4 and the barrier ring member 5. At the same time, the dust blocking conical surface 501 provided on the side of the barrier ring member 5 facing the dust reduction chamber 301 plays a key role, directly blocking the dust in the dust reduction chamber 301 from entering the air intake chamber 302 and preventing these impurities from interfering with the subsequent detection process.

[0046] Step 2. Impurity collection: The impurities falling into the dust reduction chamber 301 tend to fall downward under the continuous action of gravity. At the same time, the static electricity rod 10 configured in the collection tank 9 and inserted upward into the dust reduction chamber 301 plays a role. The static electricity rod 10 is periodically powered on and off. When the static electricity rod 10 is powered on, an electrostatic field will be formed around it, and the charged impurities will approach the static electricity rod 10 under the action of electrostatic attraction. The time interval of a single power-off is positively correlated with the moving speed of the steel wire rope 18. This is because the faster the moving speed of the steel wire rope 18, the more impurities may be generated per unit time. In order to ensure that the impurities can be fully adsorbed, it is necessary to shorten the power-off time interval of the static electricity rod 10 to make the electrostatic adsorption effect more frequent, so as to ensure that the impurities fall smoothly into the collection tank 9 under the dual action of gravity and static electricity.

[0047] Step 3. Adjust the air flow temperature: Start the intake fan 12. The operation of the fan generates suction, and the outside air is drawn into the intake filter cartridge 14. The intake filter cartridge 14 is made of a specific filtering material, which can effectively filter out impurities such as dust and particles carried in the outside air, ensuring that the air entering the subsequent system is relatively clean. The filtered air enters the cooling pipe 13. The cooling pipe 13 is made of copper pipe, which has good heat conduction performance, and a water-cooled heat exchange module is installed inside it. A temperature sensing module is configured at the intake end of the cooling pipe 13, and this module can monitor the air flow temperature entering the cooling pipe 13 in real time. According to the preset target temperature (this target temperature is set according to the optimal working temperature environment of the ultrasonic detection module 15) and the real-time air flow temperature detected by the temperature sensing module, the water-cooled heat exchange module will perform corresponding cooling operations. For example, if the real-time air flow temperature is higher than the target temperature, the water-cooled heat exchange module will increase the flow rate of the coolant or lower the temperature of the coolant to enhance the cooling effect; conversely, it will appropriately reduce the flow rate of the coolant or raise the temperature of the coolant, thereby precisely controlling the air flow temperature. The cooled air flow enters the intake cavity 302 through the intake port 304 located directly below the intake cavity 302 on the detection pipe 3. The intake port 304 is connected to the outlet end of the cooling pipe 13 through a sealing gasket, ensuring the tightness of the air flow transportation process and preventing air flow leakage.

[0048] Step 4. Form a stable detection environment: The cooled air flow entering the intake cavity 302 undergoes a flow change under the action of the air flow converging cover 11. The air flow converging cover 11 is in a horn shape and converges towards the detection cavity 303. A second channel 1101 is opened at its central position, and the steel wire rope 18 passes through this channel. The horn-shaped structure enables the air flow in the intake cavity 302 to gradually converge towards the periphery of the steel wire rope 18. During the convergence process, the air flow comes into full contact with the steel wire rope 18, cools the steel wire rope 18, and takes away the heat generated by the long-term operation of the steel wire rope 18 or the friction with other components. The cooled air flow continues to be introduced into the detection cavity 303, forming a stable and clean detection environment inside the detection cavity 303. This environment can effectively reduce the influence of temperature on the ultrasonic detection module 15, avoid the decrease in the detection accuracy of the ultrasonic detection module 15 caused by temperature changes, and ensure the accuracy of the detection results.

[0049] Step Five, Steel Wire Rope Detection: The steel wire rope 18 continuously moves within the detection chamber 303, and the ultrasonic detection module 15 located within the detection chamber 303 starts to operate. The ultrasonic detection module 15 emits ultrasonic waves, which propagate inside the steel wire rope 18. When there are defects inside the steel wire rope 18, such as broken wires, internal corrosion, etc., the ultrasonic waves will undergo reflection, refraction, or scattering during propagation. The ultrasonic detection module 15 can receive these ultrasonic signals that are reflected, refracted, or scattered back, and convert them into electrical signals. By analyzing and processing these electrical signals, combined with specific algorithms and models, the ultrasonic detection module 15 can determine whether there are defects inside the steel wire rope 18, as well as information such as the location and size of the defects. At the same time, the ultrasonic detection module 15 will transmit the detected information to the detection system in real time, and the detection system can store, display, and further analyze this information, facilitating the staff to timely understand the internal condition of the steel wire rope 18.

[0050] Step Six, Complete Detection and Remove the Steel Wire Rope: The steel wire rope 18 after being detected by the ultrasonic detection module 15 leaves the detection tube 3 through the third channel 1601 opened at the central position of the cover 16. A plurality of curved exhaust holes 1602 are opened around the third channel 1601 on the cover 16. The air flow within the detection chamber 303 is driven by the movement of the steel wire rope 18 and is discharged from the detection tube 3 through these curved exhaust holes 1602. The steel wire rope 18 that leaves the detection tube 3 is further guided by the downstream idler wheel 17 and moves out of the range of the support platform 1, completing the entire detection process.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.

The air flow converging hood (11) converges the air flow in the air intake cavity (302) towards the periphery of the steel wire rope (18), cools the steel wire rope (18), and guides it into the detection cavity (303), forming a stable and clean detection environment in the detection cavity (303) and reducing the influence of temperature on the ultrasonic detection module (15); S5. The steel wire rope (18) moves in the detection cavity (303), and the ultrasonic detection module (15) detects the steel wire rope (18) and transmits the detected information to the detection system in real time; S6. The steel wire rope (18) after the detection ends leaves the detection tube (3) from the central position of the cover (16) and moves out of the range of the support platform (1) through the guide wheel (17) on the downstream side.
