Description
Technical Field
[0001] This invention relates to the field of axial-flow propeller turbine technology, and in particular to an adjustment device and method for aligning and installing the runner's drain cone. Background Technology
[0002] Currently, during the docking and installation of the runner drain cone of the axial-flow propeller turbine unit with the upper connecting body (upper flow guide connecting seat of the unit), there are a large number of bolt holes in the connecting body, and there are certain requirements for the accuracy of the holes. Most of the existing tooling has a simple structure, only has a simple load-bearing function, a single adjustment method, and lacks a multi-dimensional coordinated adjustment structure.
[0003] In actual operation, bolt hole alignment is mainly achieved by manual prying and repeated calibration. Manual hole alignment is inconvenient, time-consuming, and labor-intensive. The tooling has a low degree of automation and poor alignment accuracy, which affects the maintenance and construction schedule of the unit. At the same time, traditional tooling lacks a dedicated working platform, making it inconvenient for operators to move up and down when performing hole alignment and tightening operations at high positions. Working at heights can easily lead to safety hazards such as collisions and falls. In addition, traditional tooling requires manual operation to achieve multi-directional adjustment of the drain cone in the horizontal, vertical, and rotational directions. During the alignment process, it is difficult to ensure the coaxiality of the drain cone and the connecting body and the overlap of the holes.
[0004] To address the aforementioned issues, an adjustment device and its usage method are now designed for the alignment and installation of the turbine runner's drain cone. Summary of the Invention

[0015] A method for using an adjustment device for aligning and installing the runner drain cone of a generator unit includes the following steps: S1: Use the load-bearing wheels at the bottom of the base to pull the device to the installation position, and use the hydraulic cylinder of the lifting mechanism to lift the main body of the frame so that the support plate is on the ground to support it, thus completing the leveling and fixing of the equipment. S2: Place the drain cone inside the receiving platform, insert and fix the bottom of the drain cone, adjust the four support arms so that the contact ends of the support rods are in contact with the side wall of the drain cone, and use the anti-tipping pressure sensor to detect the contact pressure to determine that the clamping is uniform and qualified. S3: The equipment is powered on and started. The control mechanism controls the zeroing of the origin sensors of each axis to complete the calibration and establish a mechanical reference coordinate system. The operator enters the reference coordinates, reference angle and deviation threshold of the upper connecting body through the touch screen, and at the same time presets the adjustment step and PID control parameters of each axis. S4: During operation, the X-axis displacement sensor, Y-axis displacement sensor, and rotation angle sensor collect horizontal and vertical position data and drainage cone rotation angle data in real time, and transmit the collected signals to the PLC main control module.

S6: When the X-axis deviation, Y-axis deviation and angle deviation all meet the preset thresholds and the data of multiple consecutive sampling cycles are stable without fluctuation, it is determined that the bolt holes are coaxially coincident, and the controller locks the lateral alignment mechanism, longitudinal docking mechanism and steering mechanism. S7: Workers climb the ladder to enter the work platform and complete the installation of the drain cone bolts; after installation, release the locks on each shaft, control the lifting mechanism to fall back, the hydraulic cylinder retracts, the support plate is lifted off the ground, the equipment returns to the transport state, and the drain cone alignment and installation work is completed.
[0016] This invention provides an adjustment device and method for aligning and installing the drain cone of a turbine runner, with the following advantages: By using the base, lateral alignment mechanism, longitudinal docking mechanism, steering mechanism and lifting mechanism in a coordinated manner, the overall height, base length and position can be adjusted simultaneously, as well as the circumferential angle of the drain cone. This forms a multi-dimensional and all-round adjustment, eliminating the need for repeated manual calibration, simplifying the alignment process, effectively improving the alignment efficiency between the drain cone and the bolt holes of the connecting body, and shortening the maintenance and construction period of the unit.
[0017] By using a work platform in conjunction with protective fences and access ladders, a standardized and safe high-altitude work area is constructed, replacing the unprotected work mode, effectively avoiding safety hazards such as personnel falling from heights and collisions, and improving the safety and standardization of on-site installation operations.
[0018] The lateral alignment mechanism, longitudinal docking mechanism, and steering mechanism all employ servo drives combined with sensor detection components. Together with the control mechanism, they achieve real-time acquisition and closed-loop calculation control of multiple data types, including displacement, pressure, and angle. Relying on incremental PID adjustment logic, automatic deviation correction is completed, which can control the adjustment stroke and adjustment speed of each axis, effectively improving the alignment and positioning accuracy of the drain cone and meeting the high-precision hole-fitting installation requirements of a large number of bolt holes.
[0019] By setting a slot positioning structure and a multi-directional support and limiting structure at the placement position of the drain cone, and in conjunction with pressure sensor detection, the workpiece clamping status can be determined in real time. This prevents the drain cone from shifting or shaking during multi-dimensional adjustment, ensuring both placement stability and avoiding damage to the workpiece surface, thus guaranteeing the quality of workpiece installation.
[0020] With its load-bearing wheels and traction structure, the equipment is flexible and convenient to transport, facilitating on-site relocation and deployment. It is highly adaptable to the changing construction environment of the unit maintenance site, with a reasonable and compact overall structure, smooth and stable transmission operation, strong equipment operation stability, and convenient subsequent maintenance.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] This application provides an adjustment device and method for aligning and installing the runner drain cone of a turbine unit. It can solve the problem that most existing tooling in the process of docking and installing the runner drain cone of a central axial flow propeller turbine unit with the upper connecting body has a simple structure, only has a simple load-bearing function, a single adjustment method, and lacks a multi-dimensional coordinated adjustment structure.
[0026] like Figure 1-2As shown, an adjustment device for aligning and installing a drain cone on a turbine runner includes a base 1, a transverse alignment mechanism 2 above the base 1, a longitudinal docking mechanism 3 above the transverse alignment mechanism 2, a working platform 4 around the longitudinal docking mechanism 3, a docking platform 5 above the longitudinal docking mechanism 3, and a receiving platform 6 rotatably mounted on the docking platform 5. The receiving platform 6 is used to place the drain cone. The transverse alignment mechanism 2 drives the longitudinal docking mechanism 3 to move along the length of the base 1, and the longitudinal docking mechanism 3 drives the docking platform 5 to move along the width of the base 1. A steering mechanism 7 is mounted on the longitudinal docking mechanism 3 and connected to the receiving platform 6 to drive the drain cone to rotate. A lifting mechanism 8 for adjusting the height of the base 1 is mounted at the bottom of the base 1. A control mechanism 9 is mounted on the working platform 4 to control the coordinated linkage of the transverse alignment mechanism 2, the longitudinal docking mechanism 3, the steering mechanism 7, and the lifting mechanism 8 to achieve docking between the drain cone and the connecting body.
[0027] The base 1 enables overall load-bearing and mobile deployment. During operation, the lifting mechanism 8 can be used to adjust the overall height of the base 1 to adapt to different installation height requirements.
[0028] After the drainage cone is stably placed inside the receiving platform 6 on the docking platform 5 and positioned, it can be operated on-site by the workers on the working platform 4. The control mechanism 9 installed on the working platform 4 issues control commands. The control mechanism 9 can drive the horizontal alignment mechanism 2 to move and adjust the position of the vertical docking mechanism 3 along the length of the base 1. At the same time, it can drive the vertical docking mechanism 3 to move and adjust the position of the docking platform 5 along the width of the base 1. It can also control the turning mechanism 7 on the vertical docking mechanism 3 to move and adjust the circumferential rotation angle of the receiving platform 6 and the drainage cone placed on it. Through the coordinated action of the horizontal alignment mechanism 2, the vertical docking mechanism 3, the turning mechanism 7 and the lifting mechanism 8, the drainage cone can be adjusted in multiple dimensions, including length, width, rotation angle and overall height, and finally the precise alignment and docking operation between the drainage cone and the upper connecting body can be completed.
[0029] See Figure 1 and Figure 6 As shown, in one embodiment, the base 1 includes a frame body 11, with multiple sets of load-bearing wheels 12 rotatably arranged on both sides of the frame body 11, and a traction hook provided on one side of the frame body 11; the frame body 11 has a cavity inside and an open bottom.
[0030] In actual use, the frame body 11 serves as the support of the base 1. Its internal cavity structure can reduce weight, while reserving space for the installation of the bottom lifting components. The bottom opening facilitates the lifting structure to extend downward to complete the support operation.
[0031] Multiple sets of load-bearing wheels 12 installed on both sides of the main frame 11 can support the whole unit. With the help of the traction hook, the whole unit can be moved and transported by external traction equipment to the designated installation position, meeting the needs of flexible on-site relocation and deployment.
[0032] See Figure 6 , Figure 7 and Figure 8 As shown, in one embodiment, the lateral alignment mechanism 2 includes: two slide rails 21 disposed on the top of the base 1, the two slide rails 21 being distributed along the length of the base 1; At least two sliders 22 are slidably disposed above slide rail 21, and a fixed seat 23 is disposed between two opposing sliders 22; a lead screw 24 is rotatably disposed on the top of the base 1, and a transmission cylinder 25 is threadedly connected to the outside of the lead screw 24; the lead screw 24 is located between two slide rails 21, and the transmission cylinder has a drive thread hole adapted to drive the lead screw 24; a drive motor 26 and a reducer 27 are disposed on one side of the base 1, the output shaft of the drive motor 26 is connected to the input shaft of the reducer 27, and the output shaft of the reducer 27 is connected to one end of the lead screw 24; two transmission plates 28 are disposed on the outside of the transmission cylinder 25, and the top of the transmission plate 28 is connected to either fixed seat 23.
[0033] It should be noted that positioning blocks are provided at both ends of slide rail 21. An opening is provided at the top of base 1, and two fixed plates are positioned opposite each other on the top of base 1. Bearing seats are provided on the fixed plates, and lead screw 24 is rotatably mounted between the two bearing seats. The output shaft of reducer 27 is connected to one end of lead screw 24 via a coupling. A fixed frame is provided on one side of base 1, and reducer 27 and drive motor 26 are sequentially mounted on the fixed frame from top to bottom.
[0034] In practical use, the power output by the drive motor 26 is reduced and increased in torque by the reducer 27, which drives the lead screw 24 to rotate in the bearing seat at the top of the base 1. The screw drive drives the transmission cylinder 25 to move axially along the lead screw 24. The transmission cylinder 25 drives the fixed seat 23 to move synchronously through the transmission plate 28. The fixed seat 23 slides smoothly along the slide rail 21 through the slider 22 to complete the length-to-position adjustment. The positioning blocks at both ends of the slide rail 21 can limit the sliding stroke of the slider 22 to prevent the mechanism from overtravel.
[0035] The drive motor 26 and the reducer 27 are installed in layers by a fixed bracket, which is compact and has a stable transmission connection, ensuring smooth power transmission.
[0036] The screw and nut transmission method provides smooth and high-precision transmission, enabling precise adjustment of the length displacement. Combined with slide rail 21 and slider 22 to form a sliding guide structure, the movement is smooth and the load-bearing capacity is good, effectively preventing deviation and jamming during the adjustment process. The addition of a stroke positioning structure can effectively protect the equipment structure and improve the safety of use.
[0037] The drive motor 26 is a high-precision servo motor from the Panasonic MSMF series. It has an absolute encoder inside to realize real-time feedback of speed and displacement. The reducer 27 is a planetary precision reducer with built-in speed sensing components, thereby accurately controlling the rotation stroke and operating speed of the lead screw 24. Omron mechanical travel limit sensor switches are installed at both ends of the slide rail 21 positioning block 1, which can determine the movement limit position of the slider 22 in real time, and cut off the power output in time with the electronic control signal, so as to realize precise speed control, precise limit and closed-loop position control of the length displacement.
[0038] See Figure 5 , Figure 6 and Figure 7 In one embodiment, the longitudinal docking mechanism 3 includes a support frame 31 disposed above two fixed seats 23. The support frame 31 has two slide rails 32 disposed opposite to each other. The slide rails 32 are disposed along the width of the base 1. Two sliders 33 slide opposite to each other above the slide rails 32. The docking platform 5 is disposed between the tops of the four sliders 33. Two racks 34 are disposed opposite to each other on the inner side of the support frame 31. Two drive motors 35 and reducers 36 are disposed opposite to each other on the docking platform 5. The output shaft of the drive motor 35 is connected to the input shaft of the corresponding reducer 36. The output shaft of the reducer 36 passes through and extends to the bottom of the docking platform 5. The output shaft of the reducer 36 is provided with a gear 37, which meshes with the corresponding rack 34.
[0039] The support frame 31 serves as the carrier of the longitudinal docking mechanism 3. The second drive motor 35 outputs power and after being reduced and increased in torque by the second reducer 36, it drives the first gear 37 to rotate. The meshing transmission between the first gear 37 and the rack 34 enables the docking platform 5 to generate a horizontal driving force. The docking platform 5 slides along the slide rail 32 arranged along the width of the base 1 via the slider 33, thereby realizing the linear displacement adjustment of the docking platform 5 in the width direction and completing the position adjustment of the drain cone in the Y-axis direction.
[0040] The gear and rack transmission has a large transmission stroke and fast movement speed, making it suitable for wide-range width adjustment operations. With the guide and limit of slide rail 2 32 and slider 2 33, the movement of docking platform 5 is guaranteed to be smooth, with strong load-bearing capacity and less prone to deflection. The dual motors and dual racks are symmetrically arranged, and the force is evenly distributed, effectively preventing the docking platform 5 from shifting or jamming on one side. The overall structure is simple and compact, with high rigidity and strength, and can quickly complete the width position correction.
[0041] The second drive motor (35) is a Huichuan MS1H series high-precision servo motor with a multi-turn absolute encoder that provides real-time feedback of running speed and walking displacement data. The second reducer (36) is a Zhuolan precision planetary reducer with a Hall-type speed sensor component inside, which can control the rotation speed and feed stroke of the first gear (37).
[0042] See Figure 9 In one embodiment, the work platform 4 is disposed outside the support frame 31; The work platform 4 includes a platform 41 located outside the support frame 31. The platform 41 is used for the operator to stand and walk. A fence 42 is provided around the platform 41. Two passages 43 are arranged opposite each other on the fence 42. A ladder 44 located in the passage 43 is provided on the side of the platform 41.
[0043] A chain is installed on one side of the passage 43, and a slot is installed on the other side. A pin is installed at the end of the chain away from the passage 43. The pin cooperates with the slot to block the passage 43 and prevent the operator from falling.
[0044] The platform 41 is installed on the outside of the support frame 31 to form a stable high-altitude working surface, allowing operators to stand and carry out alignment and bolt installation work.
[0045] Operators can enter and exit the platform 41 via ladder 44. Ladder 44 is set at the passage 43 of the fence 42. During daily operation, the pin at one end of the chain at passage 43 is inserted into the slot to close the passage. When personnel pass through, the pin is pulled out to open the passage and complete the personnel entry and exit control.
[0046] A dedicated work area is built using platform 41, which is suitable for high-altitude installation of drainage cones and allows personnel to operate at close range. The perimeter is enclosed by fence 42 to form a protective barrier, which greatly reduces the risk of falling from height. The ladder 44 enables convenient access up and down, effectively improving the overall safety of high-altitude operations.
[0047] See Figure 1 and Figure 2 In one embodiment, the docking platform 5 is further provided with four support arms 10 arranged in a rectangular shape, which are used to support the drainage cone. The support arm 10 includes a column 101 mounted on the docking platform 5, a support rod 102 mounted on the column 101, the support rod 102 being inclined, and a contact end 103 mounted on one end of the support rod 102. The drain cone is placed on the receiving platform 6, and the contact end 103 of the support rod 102 contacts the side wall of the drain cone, thus supporting the drain cone.
[0048] The receiving platform 6 has multiple slots on its upper surface that are adapted to the bottom of the drain cone, and the bottom of the drain cone is inserted into the upper surface of the receiving platform 6.
[0049] The receiving platform 6 uses a top slot to connect with the bottom of the drain cone, thus positioning and placing the bottom of the drain cone.
[0050] Four rectangular support arms 10 are fixed to the docking platform 5 by columns 101. The inclined support rods 102 are attached to the side wall of the drain cone by the end contact head 103, and the drain cone is laterally tightened and limited from all sides. Together with the bottom positioning structure of the receiving platform 6, the drain cone is stably placed as a whole.
[0051] The receiving platform 6 uses a slot-type positioning to limit the bottom of the drain cone, making placement convenient and secure. The support arm 10 provides lateral support and limit to the drain cone from multiple directions, ensuring strong placement stability and effectively preventing the drain cone from shifting or shaking during adjustment.
[0052] The inclined support rod 102 has good fit and uniform force distribution, which can not only ensure the stability of the support, but also avoid damage to the workpiece surface by clamping, and ensure the stability of the posture during the alignment and adjustment of the drain cone.
[0053] See Figure 2 , Figure 3 and Figure 4 In one embodiment, the steering mechanism 7 includes a slewing bearing 71 arranged above the docking platform 5. The inner ring of the slewing bearing 71 is fixed to the top of the docking platform 5, and the top of the outer ring of the slewing bearing 71 is provided with a mounting cylinder 72. The receiving platform 6 is provided on the top of the mounting cylinder 72. The steering mechanism 7 also includes a drive motor 73 and a reducer 74 disposed at the bottom of the docking platform 5. The output shaft of the drive motor 73 is connected to the input shaft of the reducer 74. The output shaft of the reducer 74 passes through and extends above the docking platform 5. The output shaft of the reducer 74 is provided with a gear 75, which meshes with the external gear ring on the outer ring sidewall of the slewing bearing 71.
[0054] The inner ring of the slewing bearing 71 is fixed to the top of the docking platform 5, so that the inner ring of the slewing bearing 71 remains stationary.
[0055] The drive motor 373 outputs power, which is reduced and increased in torque by the reducer 374, and drives the gear 375 to rotate. The gear 375 meshes with the outer ring gear of the slewing bearing 71, driving the outer ring of the slewing bearing 71 to rotate relative to the inner ring. The outer ring drives the receiving platform 6 to rotate synchronously through the mounting cylinder 72, thereby realizing the circumferential angle adjustment of the drain cone above the receiving platform 6 and completing the hole position angle calibration operation.
[0056] The slewing bearing 71 supports rotation and is adapted to the rotation adjustment of heavy-duty drain cone. The gear meshing transmission has high transmission accuracy and good self-locking, and can accurately control the rotation angle to meet the high-precision hole requirements of bolt holes.
[0057] The drive motor 373 is a Huichuan MS1H series servo motor with an absolute encoder to collect real-time operating angle and speed data. The reducer 374 is a precision planetary reducer with integrated angle detection element, which can adjust the rotation angle and start / stop speed of gear 375. The slewing bearing 71 is a single-row four-point contact ball-type external gear slewing bearing JB / T 2300-2011. The inner ring is fixed to the docking platform with 5 bolts, and the outer ring external teeth mesh with gear 3 at 75 degrees. It is suitable for medium-sized slewing loads and matches the requirements of servo drive and angle closed-loop control.
[0058] See Figure 7 and Figure 8 In one embodiment, the lifting mechanism 8 includes four hydraulic cylinders 81 disposed opposite to each other inside the frame body 11. The piston rod of the hydraulic cylinder 81 is provided with a support plate 82, which is at the same horizontal height as the load wheel. The hydraulic cylinders 81 are connected to an external hydraulic pump station through pipes to drive the frame body 11 to lift.
[0059] Four hydraulic cylinders 81 are installed inside the main frame 11. The hydraulic cylinders 81 are connected to a hydraulic pump station to obtain power, and drive the bottom support plate 82 to complete the lifting action through the extension and retraction of the piston rod.
[0060] During operation, the piston rod extends, the support plate 82 contacts the ground downwards and lifts the main body 11 of the frame, causing the load-bearing wheels to leave the ground, thus completing the overall height adjustment and stable support. During transport, the piston rod retracts, the support plate 82 retracts, the load-bearing wheels touch the ground, and the device returns to its moving state.
[0061] The machine is raised and lowered synchronously by four sets of hydraulic cylinders 81, which ensures uniform lifting force and convenient leveling. It can adapt to different installation heights. The support plate 82 increases the contact area, providing strong support stability and effectively preventing slippage and shaking during operation. The hydraulically driven lifting has sufficient power and runs smoothly. The lifting adjustment range is large, and the height can be quickly aligned. The structural layout is hidden inside the main frame 11, which maximizes space utilization and makes the overall structure simple and durable.
[0062] Hydraulic cylinder 81 is an Enpact HCL series heavy-duty cylinder. The cylinder is equipped with a VB series explosion-proof valve on the outside and has a mechanical locking nut to achieve heavy-duty anti-fall and rigid self-locking.
[0063] See Figure 1 and Figure 9 In one embodiment, the control mechanism 9 includes a housing, a sensor module, a main controller disposed inside the housing, a handheld operating terminal, and a communication module; The sensor module includes an X-axis displacement sensor, a Y-axis displacement sensor, a rotation angle sensor, a zeroing sensor, a height position sensor, and an anti-tipping pressure sensor; The X-axis displacement sensor is a magnetic grating displacement sensor, which is installed at the reference end of the slide rail 21 of the transverse alignment mechanism 2 to collect the transverse displacement in real time and prevent the mechanism from overtravel. The Y-axis displacement sensor is a magnetic grating displacement sensor, which is installed on the side of the rack 34 of the longitudinal docking mechanism 3. It works with the motor encoder to collect longitudinal travel displacement and complete the planar coordinate correction. The rotation angle sensor is an absolute encoder, coaxially mounted on the side of the slewing bearing 71 of the steering mechanism 7, and is used to collect the circumferential rotation angle of the drain cone in real time. The origin zeroing sensor is a photoelectric induction switch, which is installed on one side of slide rail 1 21 and slide rail 2 32 respectively, and is used to automatically return to zero when the machine is turned on and establish a unified mechanical coordinate system. The height position sensor is a magnetic switch, which is fixedly installed on the outside of the hydraulic cylinder 81 of the lifting mechanism 8. It is used to detect the high and low strokes of the cylinder to prevent hard collisions. An anti-tipping pressure sensor is installed inside the contact end 103 of the support arm 10 to collect the contact pressure of the support rod 102 and determine the uniformity of workpiece clamping. The main controller includes a PLC main control module, an analog signal acquisition module, a servo drive module, a hydraulic control module, a power supply module, and an emergency stop protection module; The PLC main control module is used to receive real-time signals from various sensors, calculate position and angle deviations, and output motion control commands. The analog signal acquisition module is used to acquire analog signals of displacement, angle, and pressure to achieve high-precision micro-adjustment; The servo drive module is electrically connected to the servo motors of the lateral alignment mechanism 2, the longitudinal docking mechanism 3, and the steering mechanism 7, respectively, and controls the motor start / stop, speed, and micro-feed. The hydraulic control module is a solenoid valve group that controls the hydraulic cylinder 81 of the lifting mechanism 8 to complete lifting, pressure holding, and buffering actions. The power supply module is a regulated switching power supply, which provides power to the sensors, controllers, and servo motors. The emergency stop protection module integrates hardware emergency stop, overtravel power cut-off, and overload protection functions; The handheld operating terminal consists of a touch screen and physical control buttons. The touch screen is used for human-computer interaction, parameter input, coordinate and angle display, and one-click automatic alignment. The physical control buttons include lifting buttons, shaft movement buttons, emergency stop buttons, and manual / automatic switching knobs; The communication module is used for data interaction, parameter storage, and real-time transmission between the touch screen and the PLC main control module; The control mechanism 9 has built-in incremental PID calculation logic. The equipment automatically resets to zero and establishes a reference coordinate system when it is turned on. By collecting real-time coordinate, angle and pressure signals, it automatically calculates the deviation and sequentially completes the Y-axis adjustment, X-axis PID adjustment and rotation axis angle closed-loop correction. When the position deviation and angle deviation meet the preset threshold at the same time, each axis is locked to achieve fully automatic alignment of the drain cone bolt holes.
[0064] Among them, the X-axis adjustment causes the lateral alignment mechanism 2 to move along the length of the base 1, and the Y-axis adjustment causes the longitudinal docking mechanism 3 to move along the width of the base 1.
[0065] The specific steps include: After the equipment is powered on and completes the initialization process, the sensors on each axis automatically complete the zeroing calibration, and the controller uses this to establish a unified mechanical reference coordinate system. After the drainage cone is placed on the receiving platform and the placement is completed, the pressure sensors on the inside of the four support rods detect the contact pressure in real time, and determine whether the drainage cone is clamped and fixed properly by the pressure value. The fixed reference parameters of the upper connector are entered into the touch screen as alignment and comparison references, including the theoretical center reference coordinates of the upper connector. Theoretical reference angle of bolt holes in the upper connecting body Maximum permissible deviation threshold for planar position Maximum allowable deviation threshold for angle Simultaneously preset the Y-axis adjustment step, X-axis adjustment step, rotary axis fine-tuning step, and PID adjustment parameters; Subsequently, the controller collects real-time operating data from each sensor. X and Y displacement sensors collect the real-time center coordinates of the discharge cone. The rotation angle sensor collects the real-time rotation angle of the drain cone.
[0066] The controller continuously collects real-time operating data from various sensors, uses X and Y displacement sensors to collect the real-time center coordinates of the drain cone, uses rotation angle sensors to collect the real-time rotation angle of the drain cone, and calculates the offset difference using a formula. The formula for calculating the X-axis position deviation is as follows: ; Formula for calculating Y-axis position deviation: ; The degree of overall coaxial offset between the center of the spillway cone and the center of the upper connecting body is evaluated by calculating the planar comprehensive radial deviation, which serves as the basis for switching the regulating section. The formula for calculating the planar comprehensive radial deviation is as follows: ; By calculating the angle deviation, the difference between the existing hole angle of the drainage cone and the standard hole angle of the upper connecting body is determined, providing a basis for rotation correction. The formula for calculating the angle deviation is as follows: ; By adjusting the Y-axis calculation logic, the center radial deviation can be quickly and significantly reduced, and the working condition can be quickly pulled into the adjustment range to improve alignment efficiency. To integrate radial deviation As a basis for judgment, if When the feed exceeds the set threshold, the controller outputs a control command with a fixed large step size, driving the Y-axis motor to continuously feed and gradually decrease the feed rate. Continue until the radial deviation enters the allowable adjustment range, thus completing the Y-axis adjustment.
[0067] By adjusting the PID closed-loop operation along the X-axis, the steady-state error in the X-axis position is eliminated with high precision, and overshoot and jitter are suppressed to ensure planar positioning accuracy. The controller uses the real-time acquired X-axis position deviation As the closed-loop input of the PID controller, it is substituted into the incremental PID formula for real-time calculation, and the calculation formula is as follows: ; in, This represents the current X-axis position deviation. As a proportional coefficient, it outputs an adjustment amount in real time according to the current X-axis deviation. The larger the deviation, the larger the output driving amount, which quickly moves the X-axis toward the reference coordinate and quickly reduces the position difference. This is the integral coefficient. Accumulates minute static deviations, gradually compensating for residual static errors in the proportional adjustment, ensuring the deviation approaches zero, and eliminating any fixed offset after positioning; The differential coefficient is used to predict the rate of change of the X-axis deviation. When the deviation decreases rapidly, the output driving force is weakened in advance to suppress overshoot and back-and-forth oscillation caused by the mechanism passing the reference position. The controller drives the X-axis micro-feed based on the PID calculation output, gradually converging the X-axis deviation to within the allowable range.
[0068] Specifically, the convergence process is as follows: The controller refreshes the X-axis coordinates every millisecond, updates the deviation in real time, and recalculates the PID output; when the deviation is large, the X-axis feeds rapidly with large steps; after the deviation decreases, the system automatically reduces the feed speed and the step size; it continues to converge slowly towards the reference coordinate; when the X-axis deviation falls within the allowable error range, and the deviation has no fluctuation and the rate of change approaches 0 for 5 consecutive sampling cycles, the X-axis convergence is determined to be complete, the controller locks the X-axis position, and eliminates jitter misjudgments.
[0069] Closed-loop correction of the rotation axis angle is used to precisely compensate for circumferential hole position angle differences, achieving circumferential alignment of bolt holes. With angular deviation As a closed-loop input, the controller compares the angle difference in real time and drives the rotating mechanism to make slight adjustments in forward and reverse rotation as needed, continuously reducing the angle deviation; Judgment stop condition formula: ; The alignment is completed by performing comprehensive judgment and calculation, and the position and angle are checked at the same time. Once all the error requirements are met, the automatic alignment is determined to be completed. Simultaneously satisfy Three threshold conditions are set up to lock the movement of each axis and confirm the precise alignment of the bolt holes: the stability judgment condition is that the deviation has no fluctuation for N consecutive sampling cycles and the motor speed approaches zero.
[0070] The system compares the hole positions of the upper connecting body in real time and performs three-axis linkage fine-tuning until the bolt holes are coaxially aligned. After alignment, the system locks the three axes, the platform remains stationary, and the worker installs the bolts.
[0071] The one-click automatic alignment function in this implementation plan completes parameter preset and command issuance based on the touch screen. After the equipment starts, it automatically completes the calibration of the origin of each axis to establish a unified mechanical coordinate system. The system collects the actual coordinates and rotation angle of the drain cone in real time through various sensors and automatically calculates the deviation value. According to the preset control logic, it first completes the width adjustment, then switches to incremental PID control to complete the length adjustment, and finally realizes the circumferential angle closed-loop fine adjustment. The adjustment mode and running speed are automatically switched throughout the process. When the position deviation and angle deviation reach the preset allowable range and the data status is stable, the system automatically locks each adjustment mechanism. The drain cone and the bolt holes of the upper connecting body can be automatically aligned without manual step-by-step operation.
[0072] A method for using an adjustment device for aligning and installing the runner drain cone of a generator unit includes the following steps: S1: Use the load-bearing wheels 12 at the bottom of the base 1 to pull the device to the installation position, and use the hydraulic cylinder 81 of the lifting mechanism 8 to lift the main body of the frame 11 so that the support plate 82 can be grounded and supported, thus completing the leveling and fixing of the equipment. S2: Place the drain cone inside the receiving platform 6, insert and fix the bottom of the drain cone, adjust the four support arms 10, so that the contact end 103 of the support rod 102 fits against the side wall of the drain cone, and detect the fitting pressure through the anti-tipping pressure sensor to determine that the clamping is uniform and qualified. S3: The equipment is powered on and started. The control mechanism 9 controls the origin zeroing of each axis sensor to complete the calibration and establish a mechanical reference coordinate system. The operator enters the reference coordinates, reference angle and deviation threshold of the upper connecting body through the touch screen, and at the same time presets the adjustment step and PID control parameters of each axis. S4: During operation, the X-axis displacement sensor, Y-axis displacement sensor, and rotation angle sensor collect horizontal and vertical position data and drainage cone rotation angle data in real time, and transmit the collected signals to the PLC main control module. S5: The controller calculates the deviation based on the collected data, and first controls the longitudinal docking mechanism 3 to complete the Y-axis adjustment joint, quickly correcting the radial deviation along the width of the base 1; then controls the transverse alignment mechanism 2 to complete the high-precision fine adjustment of the X-axis using PID closed-loop calculation, eliminating the static error along the length of the base 1; finally controls the steering mechanism 7 to drive the receiving platform 6 to rotate, completing the circumferential angle correction. S6: When the X-axis deviation, Y-axis deviation and angle deviation all meet the preset thresholds and the data of multiple consecutive sampling cycles are stable and without fluctuation, it is determined that the bolt holes are coaxially coincident, and the controller locks the lateral alignment mechanism 2, the longitudinal docking mechanism 3 and the steering mechanism 7. S7: The staff climbs ladder 44 to enter the work platform 4 and completes the installation of the drain cone bolts; after the installation is completed, the locking of each axis is released, the lifting mechanism 8 is controlled to fall back, the hydraulic cylinder 81 retracts, the support plate 82 is lifted off the ground, the equipment is restored to the transfer state, and the drain cone alignment and installation work is completed.
