Description

Technical Field

[0001] This utility model relates to the field of steam turbine technology, specifically to an intelligent flaw detection and testing device for steam turbine cylinder block castings. Background Technology

[0002] Steam turbine cylinders primarily utilize the thermal energy of steam to convert it into mechanical energy. After entering the cylinder, the steam expands and accelerates in the nozzles, forming a high-speed airflow. This high-speed airflow impacts the turbine blades, causing them to drive the rotor and thus output mechanical work. Intelligent flaw detection equipment for steam turbine cylinder castings can detect common defects in these castings, such as cracks and porosity, ensuring the overall performance and quality of the steam turbine.

[0003] Chinese utility model patent CN220719247U discloses a processing device for steam turbine cylinder castings, including a worktable with an opening at its upper end, a mounting plate, a first vertical plate, and a second vertical plate at the upper end of the worktable, both with mounting holes in their middle sections; a fixing mechanism including a servo motor mounted on the right side of the first vertical plate, a limiting groove on the left side of the first vertical plate, and a slide rail on the right side of the second vertical plate; and a detection mechanism including an electric push rod mounted on the right side of the mounting plate, a sliding plate at the other end of the electric push rod, a load-bearing plate on the right side of the sliding plate, and a drive motor mounted on the upper end of the load-bearing plate. This utility model, through its fixed mechanism design, facilitates stable fixing of the cylinder position, allows for various processing of the cylinder's interior, and can accommodate cylinders of different sizes, increasing the device's practicality.

[0004] To detect whether the cylinder block is deformed or the inner wall is uneven, the aforementioned turbine cylinder casting processing device is equipped with a detector. However, the aforementioned turbine cylinder casting processing device cannot promptly alert to defects. When the detector detects a defect in the cylinder inner wall, if no alarm sounds, the operator may not be able to quickly locate the problem, resulting in a longer troubleshooting time and increased repair difficulty and cost.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent flaw detection and inspection device for turbine cylinder block castings, comprising a workbench, a first upright plate fixedly installed on one side of the top of the workbench, a second upright plate installed on one side of the first upright plate, mounting holes being provided in the middle of both the first and second upright plates, a mounting plate being installed on the side of the second upright plate away from the first upright plate, an electric push rod fixedly installed on the lower part of one side of the mounting plate, a sliding plate fixedly installed at the telescopic end of the electric push rod, a drive motor fixedly installed on the upper part of the sliding plate away from the electric push rod, a rotating rod fixedly installed on the output shaft of the drive motor, one end of the rotating rod penetrating one side of the mounting plate and extending to the other side of the mounting plate, a detector fixedly installed at one end of the rotating rod, a PLC controller fixedly installed at the front of one side of the top of the workbench, and an alarm fixedly installed on one side of the PLC controller.

[0007] Furthermore, the detector, PLC controller, and alarm are electrically connected to each other.

[0008] Furthermore, support columns are fixedly installed at the four corners of the bottom of the workbench.

[0009] Furthermore, grooves are provided on both sides of the bottom of the support column, and a connector is movably arranged in the groove. An anti-slip pad is fixedly provided at one end of the connector, and the anti-slip pad is made of rubber.

[0010] Furthermore, threaded holes are provided on both sides of the bottom of the support column, and fixing bolts are movably installed in the threaded holes. The connection between the fixing bolts and the connecting parts is a movable plug-in connection.

[0011] Furthermore, a T-shaped groove adapted to the sliding plate is provided on one side of the top of the workbench.

[0012] Compared with the prior art, this utility model provides an intelligent flaw detection and inspection device for turbine cylinder block castings, which has the following beneficial effects:

[0013] 1. This intelligent flaw detection equipment for turbine cylinder block castings, through the setting of a PLC controller and an alarm, allows the PLC controller to collect and store the detection data fed back by the detector in real time, and to determine the nature, location, and severity of defects. The alarm then issues an alert in a timely manner based on the analysis results of the PLC controller, reminding staff to handle the problematic castings. This greatly facilitates maintenance personnel in quickly locating fault points, helps improve maintenance efficiency, and reduces repair costs.

[0014] 2. This intelligent flaw detection equipment for turbine cylinder block castings, through the installation of connecting parts, anti-slip pads, and fixing bolts, utilizes rubber anti-slip pads with a high coefficient of friction. This effectively increases the friction between the support column and the ground, significantly reducing the risk of slippage or displacement due to vibration and other external forces. This ensures the equipment maintains a stable position during operation, guaranteeing the accuracy and reliability of the inspection work. Simultaneously, the rubber anti-slip pads also have excellent vibration damping properties, effectively absorbing and attenuating the energy generated by equipment vibration, helping to improve the working environment and increase work comfort. By turning the fixing bolts, one end is moved out of the connecting part, releasing the limiting effect on the connecting part. The anti-slip pad is then pulled out until the connecting part moves out of the groove, thus completing the disassembly of the anti-slip pad. The reverse operation allows for installation, enabling rapid disassembly and installation of the anti-slip pads. This facilitates replacement by personnel and prevents the anti-slip performance from decreasing due to wear, further ensuring the stability of the device. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model discloses an intelligent flaw detection and inspection device for turbine cylinder block castings, including a workbench 1. A first upright plate 201 is fixedly installed on one side of the top of the workbench 1, and a second upright plate 202 is installed on one side of the first upright plate 201. A mounting hole 203 is provided in the middle of both the first upright plate 201 and the second upright plate 202. A mounting plate 301 is installed on the side of the second upright plate 202 away from the first upright plate 201. An electric push rod 302 is fixedly installed on the lower part of one side of the mounting plate 301. The telescopic end of the electric push rod 302 is fixed... A sliding plate 303 is fixedly provided. A drive motor 304 is fixedly provided on the upper part of the sliding plate 303 away from the electric push rod 302. A rotating rod 305 is fixedly provided on the output shaft of the drive motor 304. One end of the rotating rod 305 passes through one side of the mounting plate 301 and extends to the other side of the mounting plate 301. A detector 306 is fixedly provided on one end of the rotating rod 305. A PLC controller 307 is fixedly provided on the front part of one side of the top of the workbench 1. An alarm 308 is fixedly provided on one side of the PLC controller 307.

[0021] Specifically, the detector 306, the PLC controller 307, and the alarm 308 are electrically connected to each other.

[0022] In this implementation scheme, by setting up a detector 306, a PLC controller 307, and an alarm 308, the detector 306 can detect the cylinder casting and transmit the detection results to the PLC controller 307. The PLC controller 307 analyzes the data according to preset parameters. If the data exceeds the preset range, it sends an electrical signal to the alarm 308 to remind the staff to find and repair the fault in time.

[0023] Specifically, support columns 401 are fixedly installed at the four corners of the bottom of the workbench 1.

[0024] In this implementation scheme, by setting up support columns 401, the support columns 401 can provide stable support for the equipment and ensure its stable operation.

[0025] Specifically, grooves are provided on both sides of the bottom of the support column 401, and a connector 402 is movably arranged in the groove. An anti-slip pad 403 is fixedly provided at one end of the connector 402. The anti-slip pad 403 is made of rubber.

[0026] In this embodiment, by setting up a support column 401, a connector 402, and an anti-slip pad 403, the movable connector 402 allows the equipment to flexibly adjust the installation position of the anti-slip pad 403, making it suitable for various ground conditions. The rubber anti-slip pad 403 can enhance the friction between the equipment and the ground, prevent the equipment from sliding, and at the same time buffer the impact of vibration on the detection accuracy.

[0027] Specifically, threaded holes are provided on both sides of the bottom of the support column 401, and a fixing bolt 404 is movably installed in the threaded hole. The connection between the fixing bolt 404 and the connector 402 is a movable insertion.

[0028] In this embodiment, by setting up a connector 402 and a fixing bolt 404, and by using the movable plug-in design of the fixing bolt 404 and the connector 402, the anti-slip pad 403 is easy to install and remove, thus improving the maintainability of the equipment.

[0029] Specifically, a T-shaped groove 405 adapted to the sliding plate 303 is provided on one side of the top of the workbench 1.

[0030] In this embodiment, by setting a sliding plate 303 and a T-shaped slide groove 405, the T-shaped slide groove 405 provides a sliding track for the sliding plate 303, and the two side flanges of the T-shaped slide groove 405 can limit the sliding plate 303 and prevent the sliding plate 303 from coming out of the T-shaped slide groove 405.

[0031] In use, the operator places the cylinder casting into the mounting holes 203 of the first vertical plate 201 and the second vertical plate 202, and then uses a fixing mechanism to fix the cylinder casting. The specific structure of the fixing mechanism has been described in detail in a processing device for turbine cylinder castings with patent number CN220719247U, and will not be repeated here. After the cylinder casting is fixed, the operator first sets the detection parameters through the PLC controller 307, and then starts the electric push rod 302. The telescopic end of the electric push rod 302 retracts inward, driving the sliding plate 303 to move. With the cooperation of the T-shaped slide groove 405, the sliding plate 303 slides horizontally and drives the detector 306 to move through the rotating rod 305, so that it can detect cylinder castings of different depths. At the same time, the drive motor 304 is started. The output shaft of the drive motor 304 drives the rotating rod 305 to rotate, thereby adjusting the angle of the detector 306 to achieve the purpose of fully detecting the inner wall of the cylinder casting. The detection result of the detector 306 is transmitted to the PLC control. The PLC controller 307 stores and analyzes this data. If it exceeds the preset range, it transmits an electrical signal to the alarm 308, causing the alarm 308 to sound an alarm and reminding the staff to promptly find and repair the fault point of the cylinder casting. During the operation of the device, the rubber anti-slip pad 403 can effectively increase the friction between the support column 401 and the ground, reducing the risk of the equipment sliding or displacing due to external forces such as vibration. At the same time, the rubber anti-slip pad 403 also has good vibration damping performance, which can effectively absorb and attenuate the energy generated by the vibration of the equipment. When the anti-slip pad 403 needs to be replaced, turn the knob to fix the bolt 404, so that one end moves out of the connector 402, release the limit on the connector 402, pull the anti-slip pad 403 until the connector 402 moves out of the groove, and then complete the disassembly of the anti-slip pad 403. The reverse operation can be used for installation, thus realizing the quick disassembly and installation of the anti-slip pad 403, which is convenient for the staff to replace the anti-slip pad 403 and prevents the anti-slip performance of the anti-slip pad 403 from decreasing due to wear.

[0032] In summary, this intelligent flaw detection equipment for turbine cylinder block castings, through the inclusion of a PLC controller 307 and an alarm 308, allows the PLC controller 307 to collect, store, and analyze the detection data fed back from the detector 306 in real time, determining the nature, location, and severity of defects. The alarm 308, based on the analysis results of the PLC controller 307, promptly issues an alarm to alert personnel to address problematic castings. This greatly facilitates maintenance personnel in quickly locating fault points, improving maintenance efficiency and reducing repair costs. Furthermore, the inclusion of a connector 402, anti-slip pad 403, and fixing bolts 404, along with the rubber anti-slip pad 403's high coefficient of friction, effectively increases the friction between the support column 401 and the ground, significantly reducing the risk of equipment failure due to friction. To mitigate the risk of slippage or displacement due to external forces such as vibration, this device ensures stable operation, guaranteeing the accuracy and reliability of testing. The rubber anti-slip pad 403 also possesses excellent vibration damping properties, effectively absorbing and attenuating the energy generated by equipment vibration, thus improving the working environment and enhancing comfort. By turning the knob to fix the bolt 404, one end is moved out of the connector 402, releasing the constraint on the connector 402. The anti-slip pad 403 is then pulled out until the connector 402 moves out of the groove, completing the disassembly of the anti-slip pad 403. The reverse operation allows for installation, enabling quick disassembly and installation of the anti-slip pad 403. This facilitates replacement by staff and prevents wear and tear on the anti-slip pad 403, further ensuring the stability of the device.
