Description

Technical Field

[0001] The present invention relates to the technical field of steam turbine installation and maintenance, and particularly to a processing system and a processing method for the anchor bolt holes of a steam turbine. Background Art

[0002] During the operation of a steam turbine, with the development of technology and the increase in production requirements, it is common for the power of the steam turbine to increase. Under the original design, the existing anchor bolt holes and supporting bolts of the steam turbine can only meet the fastening requirements within a certain power range. When the power of the steam turbine exceeds the original design standard, the fastening torque provided by the original anchor bolts is difficult to maintain the stable operation of the steam turbine, posing a safety hazard.

[0003] The traditional treatment method usually involves replacing the anchor bolts with longer or thicker specifications. However, due to the limitation of the original bolt hole size, it is often impossible to directly install them, and there is a lack of effective bolt hole modification methods. In actual operation, if the bolts are directly forced to be replaced or the bolt holes are simply processed, problems such as thread damage and hole position deviation are likely to occur, further affecting the installation accuracy and stability of the steam turbine.

[0022] The switch control module is used to control the switch action of the processing execution mechanism.

[0023] In this embodiment, a processing method for a steam turbine anchor bolt hole processing system is also constructed, which is based on the steam turbine anchor bolt hole processing system, and includes:

[0024] Step S1: Install the positioning mechanism on the steam turbine through bolts and gaskets, ensure that the positioning mechanism is parallel to the steam turbine platform, and install the processing execution mechanism on the positioning mechanism;

[0025] Step S2: Install the deepening drill bit on the drilling machine, input the drilling depth parameter and the drilling path in the parameter setting module, and use the switch control module to control the processing execution mechanism to perform drilling;

[0026] Step S3: If in step S2, the processing execution mechanism can complete the processing of the drilling depth parameter for the anchor bolt hole of the steam turbine, the processing is ended;

[0027] If the anchor bolt hole is damaged or the first drilling depth parameter cannot be completed during the processing of the anchor bolt hole of the steam turbine by the processing execution mechanism, step S4 is executed;

[0028] Step S4: Use a measuring tool to measure the size and position parameters of the original anchor bolt holes of the steam turbine and input them into the parameter setting module. Replace the deepening drill bit with a reaming drill bit, input the reaming parameters and the reaming path in the parameter setting module, and use the switch control module to control the processing execution mechanism to perform drilling.

When the preset effect cannot be achieved by the deepening drill bit, the diameter of the anchor bolt hole is enlarged using a reaming drill bit as an effective remedial measure to ensure the smooth completion of the processing work, improving the success rate and reliability of the processing.

Thus, the features defined with "first", "second", "third", etc. may explicitly or implicitly include one or more of such features. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Please refer to Figure 1 , which is a machining system for the anchor bolt holes of a steam turbine in some embodiments of the present invention. It includes a positioning mechanism 1, a machining execution mechanism 2, a calibration mechanism, a data acquisition mechanism, and a control mechanism; the positioning mechanism 1 is installed on the steam turbine 3; the machining execution mechanism 2 is installed on the positioning mechanism 1 and is used for machining the anchor bolt holes of the steam turbine 3; the calibration mechanism is used to calibrate the relative positions of the positioning mechanism 1 and the steam turbine 3 and the relative positions of the positioning mechanism 1 and the machining execution mechanism 2; the data acquisition mechanism is used to acquire the operating data parameters during the machining process of the machining execution mechanism 2; the control mechanism is communicatively connected to both the machining execution mechanism 2 and the data acquisition mechanism, and controls the actions of the machining execution mechanism 2 and processes and analyzes the operating data parameters.

[0045] Specifically, the positioning mechanism 1 can be a positioning mounting plate, which can be installed on the steam turbine 3. When installing, ensure that the positioning holes on the positioning mounting plate are accurately aligned with the positions of the anchor bolt holes to be machined on the steam turbine 3 and are firm and stable, and then install the machining execution mechanism 2 on the positioning mounting plate. The calibration mechanism calibrates the relative positions of the positioning mechanism 1 and the steam turbine 3 and the relative positions of the positioning mechanism 1 and the machining execution mechanism 2. The calibration mechanism can be a laser calibration module to ensure that the coaxiality error between the drill bit of the machining execution mechanism 2 and the anchor bolt hole to be machined is ≤0.1 mm.

[0046] In some embodiments, the processing execution mechanism 2 includes a drilling machine and a drill bit connected to the drilling machine. The drill bit is provided with a nano-titanium carbide coating, which can significantly improve the wear resistance and hardness of the drill bit, enhance the corrosion resistance of the drill bit, and reduce frictional heat. The drill bit is a deepening drill bit or a reaming drill bit. The deepening drill bit can be used to directly deepen the drilling of the anchor bolt holes of the steam turbine 3, and the reaming drill bit can be used to ream the anchor bolt holes of the steam turbine 3. Specifically, the reaming drill bit is a carbide reaming drill with adjustable diameter. The adjustable-diameter reaming drill is a reaming tool that can adjust the hole diameter. It usually consists of multiple drill bits with adjustable spacing, and the position and spacing of the drill bits can be flexibly adjusted according to needs, thereby changing the size of the hole diameter. This design makes the adjustable-diameter reaming drill suitable for a variety of different processing requirements and has high flexibility and applicability. The drilling machine can be a hydraulic drilling machine.

[0047] In addition, the data acquisition mechanism includes a temperature sensor, a pressure sensor, a torque sensor, and a vibration sensor. The temperature sensor is used to measure the temperature parameters during the processing of the processing execution mechanism 2; the pressure sensor is used to measure the output pressure during the processing of the processing execution mechanism 2; the torque sensor is used to measure the output torque during the processing of the processing execution mechanism 2; the vibration sensor is used to measure the vibration amplitude during the processing of the processing execution mechanism 2. The operating data parameters collected by the temperature sensor, pressure sensor, torque sensor, and vibration sensor can be transmitted to the control mechanism, which includes a PLC controller. If the collected operating data parameters are abnormal, the drilling can be paused and an alarm can be issued.

[0048] Furthermore, the control mechanism includes a parameter setting module, a data processing module, and a switch control module. The parameter setting module is used to input the start parameter information of the processing execution mechanism 2; the data processing module is used to process the operating data parameters collected by the data acquisition mechanism and the start parameter information of the parameter setting module; the switch control module is used to control the switch action of the processing execution mechanism 2. Specifically, the start parameter information can include other parameters such as drilling depth parameters, drilling path parameters, reaming diameter parameters, tapping torque parameters, etc. The drilling depth parameter is determined according to the calculated increase in torque demand to ensure that the new bolt hole depth can accommodate a longer anchor bolt, thereby increasing the tightening torque. For example, if the original depth of the anchor bolt hole of the steam turbine 3 is H1, and the bolt length increment corresponding to the increased torque calculated according to the power increase is ΔL, then the new depth of the anchor bolt hole of the steam turbine 3, H2 = H1 + ΔL.

[0049] In this embodiment, as Figure 2 shown, a processing method for a steam turbine anchor bolt hole processing system is also constructed. Based on the above steam turbine anchor bolt hole processing system, it includes:

[0050] Step S1: Install the positioning mechanism 1 on the steam turbine 3 through bolts and gaskets, ensure that the positioning mechanism 1 is parallel to the platform of the steam turbine 3, and install the processing actuator 2 on the positioning mechanism 1;

[0051] Step S2: Install the deepening drill bit on the drilling machine, input the drilling depth parameter and the drilling path in the parameter setting module, and use the switch control module to control the processing actuator 2 to drill;

[0052] Step S3: If in Step S2, the processing actuator 2 can complete the processing of the drilling depth parameter for the anchor bolt hole of the steam turbine 3, the processing is ended;

[0053] If the anchor bolt hole is damaged or the first drilling depth parameter cannot be completed during the processing of the anchor bolt hole of the steam turbine 3 by the processing actuator 2, then Step S4 is executed;

[0054] Step S4: Use a measuring tool to measure the size and position parameters of the original anchor bolt hole of the steam turbine 3 and input them into the parameter setting module, replace the deepening drill bit with a reaming drill bit, input the reaming parameter and the reaming path in the parameter setting module, and use the switch control module to control the processing actuator 2 to drill.

[0055] It can be understood that when the anchor bolt hole is damaged during the processing with the deepening drill bit, such as cracks occur, or in case of failure such as unable to reach the expected depth, the reaming drill bit can be used to ream the anchor bolt hole. First, use a measuring tool to accurately measure the size and position parameters of the original anchor bolt hole of the steam turbine 3 and input them into the parameter setting module, and adjust to a suitable initial diameter. Then start the reaming drill bit, rotate and advance slowly, and gradually expand the diameter of the anchor bolt hole. During the reaming process, it is necessary to closely monitor the change of the hole diameter and the quality of the hole wall, and operate according to the pre-designed reaming size requirements. For example, if the original diameter of the anchor bolt hole is D1, and it is determined according to calculations and actual situations that the diameter needs to be expanded to D2, then the reaming operation needs to uniformly expand the hole diameter from D1 to D2.

[0056] Furthermore, after processing the anchor bolt hole of the steam turbine 3 with the deepening drill bit or the reaming drill bit, use a tap to thread the anchor bolt hole of the steam turbine 3; during the threading process, adopt a segmented threading process, and inject high-strength thread glue after each segment of threading. It can be understood that use a suitable tap to re-thread the entire anchor bolt hole, and the threading process adopts a segmented and progressive method to ensure the accuracy and strength of the thread to fit the new anchor bolt. In this embodiment, the threading process adopts a two-stage threading process. First, use a tap to roughly thread 60% of the depth of the anchor bolt hole, and then finely thread the remaining depth of the anchor bolt hole. Inject high-strength thread glue after each segment of threading to improve the shear resistance of the thread.

[0057] After the tapping process is completed, an endoscope is used to detect the smoothness of the hole wall of the anchor bolt hole of the steam turbine 3, and a torque tester is used to verify the torque value of the anchor bolt hole of the steam turbine 3, so as to detect whether the processed anchor bolt hole meets the processing requirements.

[0058] During the process of the processing actuator 2 machining the anchor bolt hole of the steam turbine 3, a temperature sensor is used to measure the temperature parameters during the machining process of the processing actuator 2, a pressure sensor is used to measure the output pressure during the machining process of the processing actuator 2, a torque sensor is used to measure the output torque during the machining process of the processing actuator 2, and a vibration sensor is used to measure the vibration amplitude during the machining process of the processing actuator 2. If the actual temperature parameter exceeds the preset temperature parameter, the actual output pressure exceeds the preset output pressure, or the actual output torque exceeds the preset output torque, the machining is paused and an alarm is given. Among them, the preset temperature parameter is 150 °C. If the actual temperature parameter exceeds 150 °C, the drilling speed of the drill bit is increased and the coolant flow rate is increased. If the actual output pressure exceeds the preset output pressure, or the actual output torque exceeds the preset output torque, the machining is paused and an alarm is given. If the actual vibration amplitude exceeds the preset vibration amplitude, the feed speed of the drill bit is automatically adjusted, ensuring the safety and stability during the machining process.

[0059] In addition, during the process of the processing actuator 2 machining the anchor bolt hole of the steam turbine 3, coolant is continuously injected. The coolant after machining is recycled to the liquid storage tank through a filtering device, and the debris generated during the machining process is separated by a magnetic attraction device. It can be understood that coolant needs to be continuously injected during the drilling process to reduce the temperature of the drill bit, reduce wear and prevent overheating and deformation of the hole wall. And the steam turbine anchor bolt hole processing system adopts a closed cooling system. After machining, the coolant is recycled to the liquid storage tank through a filtering device, the debris is separated by a magnetic attraction device, and the debris generated by reaming is compressed into blocks by a crusher, which is convenient for transportation and recycling.

[0060] During the process of the processing actuator 2 machining the anchor bolt hole of the steam turbine 3, the data processing module processes the operation data parameters collected by the data acquisition mechanism and the start parameter information of the parameter setting module. At the same time, the start parameter information is uploaded to the cloud database of the data processing module, and the remaining life of the anchor bolt hole of the steam turbine 3 is predicted through the AI model of the data processing module and maintenance suggestions are generated. Specifically, the aperture parameter and tapping torque parameter of the anchor bolt hole can be uploaded to the cloud database. The remaining life of the anchor bolt hole is predicted through the AI model and maintenance suggestions are generated. A life prediction model is established based on the processing data to early warn of the maintenance requirements of the anchor bolt hole, facilitating future maintenance and management.

[0061] In summary, the beneficial effects of the steam turbine anchor bolt hole machining system and its machining method are as follows: The machining method of the steam turbine anchor bolt hole machining system provides two targeted solutions. When directly increasing the depth of the anchor bolt hole by deepening the drilling depth, the torque enhancement after the subsequent installation of the anchor bolt is relatively simply and directly achieved, reducing large-scale modifications to the original structure. When the preset effect cannot be achieved by the deepening drill bit, the diameter of the anchor bolt hole is increased using a reaming drill bit as an effective remedial measure to ensure the smooth completion of the machining work, improving the success rate and reliability of the machining. Combining the collaborative machining mode of "deepening + local diameter expansion" optimizes the structural strength of the anchor bolt hole. It reduces the downtime caused by problems with the steam turbine 3 anchor bolts, improves production efficiency, and reduces the economic losses of the enterprise. At the same time, through the setting of the calibration mechanism, the coaxiality error between the drill bit of the machining actuator 2 and the anchor bolt hole to be machined is ensured. Through the setting of the data acquisition mechanism and the control mechanism, intelligent control is achieved, improving the machining accuracy of the anchor bolt hole and ensuring the safety and stability during the machining process.

[0062] It can be understood that the above embodiments only represent the preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention patent; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can also be made, all of which belong to the protection scope of the present invention; therefore, all equivalent transformations and modifications made to the scope of the claims of the present invention should fall within the scope covered by the claims of the present invention.
