Description

Technical Field

[0001] This invention relates to the field of water conservancy and hydropower engineering, and in particular to a safe operation method and system for a multi-functional platform for vertical shaft steel pipes. Background Technology

[0002] In water conservancy and hydropower projects, pressure steel pipes are the core component of the water conveyance system, undertaking the task of transporting high-pressure water. Their construction quality directly affects the safety and operational efficiency of the power station. However, traditional vertical shaft pressure steel pipe construction faces numerous challenges, such as high risks associated with high-altitude operations, low construction efficiency, and difficulty in guaranteeing welding quality. Based on this, a multi-functional installation platform for pressure steel pipes was developed (patent publication number: CN120844783A). Through the cooperation of a locking device and a lifting device, the platform can achieve stable locking and lifting. The roller arrangement of the seam-pressing device allows the steel pipe to rotate slightly around its axis during seam pressing, facilitating better alignment of the pipe ends. The platform enables construction personnel to efficiently and safely complete seam-pressing and welding operations inside the pressure steel pipe.

[0003] However, there are certain safety hazards when using the aforementioned multi-functional installation platform for pressure steel pipes in deep vertical shaft construction. Therefore, there is an urgent need to propose a safe operation method and system for a multi-functional platform for vertical shaft steel pipes. Summary of the Invention

The minimum working length L1 at which the locking device can still achieve locking under extreme operating condition 1 was calculated, and the minimum working length L2 at which the locking device can still achieve locking under extreme operating condition 2 was calculated. Determine the minimum working length L of the support mechanism min L min =min(L1, L2); S2: A laser rangefinder sensor is installed in the locking device to measure the working length of the support mechanism in real time. If it is less than the minimum working length L... min If the situation is not resolved, an alarm will be triggered in real time. At this time, the locking device will automatically lock and the self-climbing device will automatically stop working. Manually unlocking the locking device allows the support mechanism to continue extending. When the sensor measures in real-time that the working length of the support mechanism is greater than the minimum working length L... min When the alarm is triggered, the self-climbing device will automatically deactivate and resume normal operation. A weighing sensor is installed at each lifting cable of the self-climbing device to detect the working load of each lifting cable. Once the force difference exceeds the preset value, an alarm is triggered in real time, and the self-climbing device automatically stops working. The load distribution is adjusted manually. When the force difference is less than the preset value, the self-climbing device starts to work normally.

[0007] Preferably, in step S2, a laser rangefinder is provided at each support mechanism of the locking device to measure the working length of each support mechanism in real time.

[0011] Preferably, the method further includes: establishing a simulation model, analyzing the load of the self-climbing device under normal and extreme working conditions, and determining the preset value of the force difference of the self-climbing device based on the simulation results.

[0012] Preferably, a protective cover is provided on the top of the platform.

[0013] Preferably, the method further includes: setting an H-type clamp at the opening of the preceding steel pipe segment, using the H-type clamp to secure the following steel pipe segment, gradually switching the lifting cable hook to the opening of the following steel pipe segment, removing the H-type clamp, and then lowering the following steel pipe segment into place.

[0014] In a second aspect, the present invention provides a safety operating system for a multi-functional platform for vertical shaft steel pipes, comprising: A laser rangefinder sensor is installed on the locking device to measure the working length of the support mechanism in real time. Weighing sensors, installed on the self-climbing device, detect the working load of each lifting cable; The first alarm is triggered when the measured working length of the support mechanism is less than the minimum working length L. min When this happens, an alarm will be triggered; The second alarm will sound when the force difference of the lifting cable exceeds a preset value; The control system automatically locks the locking device and stops the self-climbing device when the first alarm sounds; it also automatically stops the self-climbing device when the second alarm sounds.

[0015] Preferably, once the locking device has locked, the control system prevents the retractable mechanism from extending or retracting.

[0016] Preferably, it also includes a human-machine interface for setting the lower limit length of the support structure, setting a preset value for the difference in cable stress, and operating to unlock.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a safe operation method and system for a multi-functional platform for vertical shaft steel pipes. By establishing a simulation model and determining the minimum working length of the support mechanism based on the simulation results, the locking device can still lock even after the two support mechanisms detach from the pipe wall, achieving a pre-emptive safety backup. By setting up laser rangefinders and weighing sensors for real-time measurement and alarms, combined with safety measures such as automatic locking and automatic stop interlocking, the stability of locking and climbing can be improved. Therefore, this invention can significantly improve the operational safety of the multi-functional platform for vertical shaft steel pipes. Attached Figure Description

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0033] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer," etc., used in the description of specific embodiments of the present invention to indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0034] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the solution of the present invention.

[0035] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0036] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0037] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to connection methods commonly used in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0038] Example 1 like Figure 7 As shown, a multi-functional platform for vertical shaft steel pipes mainly includes a locking device 1, a seam sealing device 2, a self-climbing device 3, an upper working platform 4, a lower working platform 5, a movable working platform 6, and a supporting body 7.

[0039] A safe operation method for a multi-functional platform for vertical shaft steel pipes includes the following steps: S1: Establish a simulation model to analyze the locking performance of locking device 1 under normal and extreme working conditions.

[0040] In normal operating conditions, all support mechanisms 11 of the locking device 1 abut against and lock to the steel pipe wall. For example, Figure 1 As shown, the four sets of wedge-shaped support mechanisms 11 all overlap by more than 15mm.

[0041] Extreme operating conditions include extreme operating condition 1 and extreme operating condition 2.

[0042] Extreme condition 1: The locking device 1 moves along a certain group of support mechanisms 11, and one support mechanism 11 detaches from the pipe wall. Under this condition, different working lengths are set for the support mechanisms, and the minimum working length L1 that the locking device can still achieve locking under extreme condition 1 is calculated.

[0043] Specifically, different working lengths are set for the support mechanisms, and the set of working lengths C1 that can still be locked after a support mechanism 11 is detached from the pipe wall is calculated. The minimum value is selected from C1 as the minimum working length L1.

[0044] For example, such as Figure 2 As shown, a certain working length is set. At this working length, the platform translates 30mm along a certain set of support mechanisms 11. At this time, the locking length of the opposite support mechanism 11 increases, while the locking length of the vertical support mechanism 11 remains unchanged. The simulation calculation only considers the locking forces of the two sets of support mechanisms 11 in the vertical direction. Figure 3As shown, the maximum stress calculated at this time is about 230 MPa, which is less than the material yield strength. Therefore, it is possible to achieve locking even after one support mechanism 11 is detached from the pipe wall.

[0045] Extreme condition 2: Locking device 1 tilts and moves horizontally, and the two support mechanisms 11 detach from the pipe wall. Under this condition, different working lengths are set for the support mechanisms, and the minimum working length L2 that the locking device can still achieve locking under extreme condition 2 is calculated.

[0046] For example, such as Figure 4 As shown, a certain working length is set. At this working length, the platform translates 30mm along a 45° direction along a certain set of support mechanisms. At this time, the locking length of the two adjacent sets of support mechanisms increases, and the other two sets of support mechanisms slide off the pipe wall. At this time, the platform is in a state of single-sided suspension with the upper support mechanism 11 bearing the weight and the lower part supported by the pipe wall. Figure 5 As shown, the calculated maximum stress is approximately 216 MPa, which is less than the material's yield strength. Therefore, the two support mechanisms 11 can still achieve locking after detaching from the pipe wall. Finally, based on the minimum working lengths L1 and L2, the minimum working length L of the support mechanism is determined. min L min =min(L1,L2), ensuring that the platform will not fall under any conditions.

[0047] For example, locking device 1 adopts a wedge-shaped design with a minimum locking area of ​​160mm × 15mm and a preset lower locking limit of 15mm, selected according to a safety factor of 1.5 or higher. Based on the bevel shape of the 34mm steel pipe, the lockable length is approximately 20mm. As the wall thickness of the steel pipe increases, the lower limit of the locking length can be increased accordingly, resulting in a higher safety factor.

[0048] S2: As Figure 6 As shown, a laser rangefinder 8 is installed in the locking device 1 to measure the working length of the support mechanism 11 in real time.

[0049] A laser rangefinder 8 is installed at each support mechanism 11 of the locking device 1, with a measurement accuracy of 0.5 mm, to measure the working length of each support mechanism 11 in real time. The sensors provide real-time feedback on the working length of the support mechanism 11, ensuring that the working length of the locking clamp is greater than the minimum working length L. min .

[0050] If the measured working length of the support mechanism 11 is less than the minimum working length L minIf the situation is triggered, an alarm will sound in real time. At this time, locking device 1 will automatically lock, and self-climbing device 3 will automatically stop working, so that the pipe hook will always be under tension and cannot be disengaged. At the same time, the pressing cylinder will also automatically lock, preventing subsequent pressing operations. At this time, manual operation can release the locking device 1, and the support mechanism 11 will continue to extend. When the sensor measures in real time that the working length of the support mechanism 11 is greater than the minimum working length L, the system will continue to extend. min When the alarm is automatically deactivated, the self-climbing device 3 will start working normally, allowing subsequent self-climbing or seam pressing operations to proceed.

[0051] Optionally, a laser rangefinder 8 is provided at each support mechanism 11 of the locking device 1 to measure the working length of each support mechanism 11 in real time.

[0052] Optionally, once the locking device 1 is locked, the retractable mechanism cannot be extended or retracted. The length of the retractable mechanism can only be adjusted after the lock is released on the human-machine interface.

[0053] like Figure 6 As shown, a load cell 9 is installed at each lifting cable 31 of the self-climbing device 3 to detect the working load of each lifting cable 31 and provide real-time feedback on the working load during lifting. If the force difference exceeds a preset value, an alarm is triggered, and the self-climbing device 3 automatically stops working. The load distribution is manually adjusted, and when the force difference is less than the preset value, the self-climbing device 3 resumes normal operation.

[0054] Optionally, the four electric hoists of the self-climbing device 3 can lift simultaneously or individually, and the two lifting modes are interlocked. When switching from one mode to another, it is necessary to select and switch on the operation interface.

[0055] Optionally, it also includes: establishing a simulation model, analyzing the load of the self-climbing device 3 under normal and extreme working conditions, and determining the preset value of the force difference of the self-climbing device based on the simulation results.

[0056] For example, the self-climbing device 3 includes four 7.5t electric chain hoists, hooks, cables, etc. By simulating and selecting a suitable preset value for the force difference, the lifting subsystem can climb even if one set of forces fails, and lock itself if two sets fail. Simultaneously, each subsystem can serve as a safety backup for the others during use, further enhancing safety.

[0057] Optionally, a protective cover can be installed on top of the platform as a protective layer to block potential risks such as falling objects and improve the safety of the platform during use.

[0058] By implementing the above steps, the safety and stability of the multi-functional platform for vertical shaft steel pipes can be improved during use, and safety accidents caused by the failure of locking device 1 and self-climbing device 3 can be effectively prevented.

[0059] Example 2 Based on Example 1, such as Figures 7-8 As shown, this embodiment also includes at least three sets of adjustable rollers 10 on each platform (including the upper working platform 4 and the lower working platform 5). These rollers 10 can roll along the wall of the steel pipe. For example, four sets of adjustable rollers 10 are provided on each platform, for a total of eight sets. These rollers 10 can adjust the gap between the platform and the inner wall of the steel pipe, preventing the platform from swaying during operation and lifting. The rollers 10 are designed to roll along the steel pipe wall, avoiding jamming during lifting and ensuring the stability of the platform during operation.

[0060] The potential failure scenarios of the guide wheel 10 were fully analyzed and demonstrated, mainly considering the following two extreme working conditions: Extreme working condition 1: The wheel 10 fails, the locking device 1 moves horizontally along a certain group of support mechanisms 11, and one support mechanism 11 is detached from the pipe wall; Extreme condition 2: The wheel 10 fails, the locking device 1 tilts and moves horizontally, and the two support mechanisms 11 detach from the pipe wall.

[0061] Based on the simulation results, the minimum working length L1 required for the locking device to achieve locking under extreme condition 1 and the minimum working length L2 required for locking under extreme condition 2 were calculated. Finally, based on the minimum working lengths L1 and L2, the minimum working length L of the support mechanism was determined. min L min =min(L1,L2), so that the two support mechanisms 11 of the locking device 1 can still be locked after they are detached from the pipe wall, ensuring that the platform will not fall under any conditions.

[0062] Example 3 Based on Embodiment 1, this embodiment further includes: setting an H-shaped clamp 12 at the opening of the preceding steel pipe segment 13; using the H-shaped clamp 12 to secure the following steel pipe segment 14; gradually shifting the lifting cable 31 hook to the opening of the following steel pipe segment 14; removing the H-shaped clamp 12; and then lowering the following steel pipe segment 14 into place. The specific structure of the H-shaped clamp 12 is as follows... Figure 13 As shown.

[0063] Specifically: Step 1: As Figure 9 As shown, an H-type clamp 12 is installed at the pipe opening of the previous section of steel pipe 13.

[0064] Specifically, during the installation of the vertical shaft steel pipe, after the previous section of steel pipe 13 has been positioned and fixed, an H-type clamp 12 needs to be installed at its top opening. The H-type clamp 12 is installed on the outer wall of the steel pipe to support the subsequent lowered steel pipe sections and ensure the safety and reliability of the installation process.

[0065] Step 2: Secure the next section of steel pipe 14 using H-type clamp 12.

[0066] The next section of steel pipe 14 is hoisted to the installation position using the steel pipe hoisting rope 15, and then slowly lowered to the joint with the previous section of steel pipe 13, so that its weight rests on the installed H-type clamp 12. The H-type clamp 12 then bears the entire weight of the next section of steel pipe 14, preventing the steel pipe from falling and ensuring the safety of the installation process.

[0067] Step 3: As Figures 10-11 As shown, the lifting cable 31 hook is gradually switched to the pipe opening of the next section of steel pipe 14.

[0068] Once the next section of steel pipe 14 is stably secured on the H-type clamp 12, the hook of the lifting cable 31 is gradually moved from its original position to the opening of the next section of steel pipe 14. During this process, it is crucial to ensure that the steel pipe lifting rope 15 maintains appropriate tension so that it can immediately bear the weight of the steel pipe after the H-type clamp 12 is removed. A load cell 9 is installed on the self-climbing device 3 to provide timely feedback on the working load during lifting. If uneven stress occurs, the system will issue an alarm.

[0069] Step Four: As Figure 12 As shown, remove the H-type clamp 12, and then lower the next section of steel pipe 14 into place.

[0070] Once the hook on the lifting cable 31 has been fully switched to the opening of the next section of steel pipe 14 and confirmed to be secure, the operator retreats to a safe position and removes the H-type clamp 12 from the outer wall of the steel pipe. Subsequently, by controlling the steel pipe hoisting rope 15, the next section of steel pipe 14 is slowly lowered to precisely align with the previous section of steel pipe 13.

[0071] The specific structural form of H-type clamp 12 is as follows: Figure 13 As shown, the steel pipe installation method using the H-type clamp 12 described above can effectively ensure the safety and reliability of the vertical shaft steel pipe installation process, reduce the risk of steel pipe falling during installation, and improve installation efficiency.

[0072] Example 4 A safety operating system for a multi-functional platform for vertical shaft steel pipes includes: A laser rangefinder 8 is installed on the locking device 1 to measure the working length of the support mechanism 11 in real time. The laser rangefinder 8 has a measurement accuracy of 0.5mm and can provide real-time feedback on the working length of the locking device 1, ensuring that the working length of the locking device 1 meets the minimum locking length preset by the system.

[0073] The load cell 9, installed on the self-climbing device 3, detects the working load of each lifting cable 31. For example, the load cell 9 can provide timely feedback on the working load during lifting and monitor the force on the four electric hoists.

[0074] The first alarm is connected to the laser rangefinder 8. When the measured working length of the support mechanism 11 is less than the minimum working length, the alarm will activate. Lmin The system will issue real-time alarms. For example, the system's preset minimum working length... Lmin The length is 15mm, when the clamp is less than the minimum working length L. min When this happens, the first alarm will immediately trigger an alarm signal.

[0075] The second alarm is connected to the load cell 9. When the force difference on the lifting cable 31 exceeds a preset value, an alarm is triggered. If uneven load distribution occurs during the lifting process, the second alarm will immediately issue an alarm signal to remind the operator to make adjustments.

[0076] The control system is connected to the first and second alarms. When the first alarm sounds, the locking device 1 automatically locks and the self-climbing device 3 automatically stops working. At this time, the electric hoist will automatically lock and stop working, and lowering operation is not allowed. This ensures that the pipe hook remains under tension and cannot be disengaged. The pressing cylinder will also automatically lock, preventing subsequent pressing operations. When the second alarm sounds, the control system will control the self-climbing device 3 to automatically stop working to prevent safety hazards caused by uneven force.

[0077] The human-computer interface is used to set the minimum working length L of the support structure. min The preset value of the force difference of cable 31 is increased, and the operation is unlocked.

[0078] In a preferred embodiment, when the locking length of the locking device 1 is less than the lower limit, the locking device 1 cylinder needs to be unlocked on the human-machine interface first, and the locking device 1 is manually operated to continue to extend. When the minimum locking length preset by the system is met, the alarm is automatically released, and the electric hoist and the pressing cylinder are automatically unlocked before subsequent self-climbing or pressing operations can be carried out.

[0079] In another preferred embodiment, when the lifting cable 31 experiences uneven stress, the operator can switch the lifting mode via the human-machine interface, from synchronized lifting to individual lifting. After adjusting the load distribution using single-action lifting, the operator can switch back to synchronized lifting mode. The four electric hoists can lift synchronously or individually, and the two lifting modes are interlocked. Switching from one mode to another requires selection on the operating interface; there are interlocks at both the electrical system program and operational levels.

[0080] Once the locking clamp is engaged, the hydraulic cylinder will automatically lock and cannot extend or retract. Operating the cylinder at this point will not cause it to move, thus not reducing the locking length. The length of the locking cylinder can only be adjusted after the locking mechanism is released via the human-machine interface. Therefore, there is actually no preset length in operation after locking.

[0081] Furthermore, the human-machine interface features a real-time dashboard: operators can view the overall operating status of all key equipment via the central HMI, covering: Lifting point load: Real-time display of the load sensor values ​​to monitor the load distribution on the platform.

[0082] Hydraulic system: Monitors key parameters such as hydraulic pressure, temperature, and oil level.

[0083] Device status: View real-time data of each functional unit, such as no-code seam pressing and pipe locking.

[0084] Full-cycle data traceability: The system automatically records all sensor data (including seam size, pressure, locking status, tension, etc.) once per second, and generates an independent data file every day.

[0085] One-click automatic control: Operators can set the target extension size, maximum working pressure, and safe retraction position for any or all support mechanisms 11 on the interface. By clicking "Automatic Extension," the system drives all hydraulic cylinders to work together to accurately complete the circumferential seam pressing; after the operation is completed, it can be "Automatically Retracted" with one click, greatly simplifying the operation process and completely replacing the traditional time-consuming and labor-intensive manual welding process. Data from the entire construction process is automatically recorded and visualized for monitoring, making the construction status clear at a glance in real time, successfully achieving the transformation from "experience-driven construction" to "data-supported construction."

[0086] The user-friendly human-computer interaction interface integrates complex multi-device control into one, supports one-click automated processes, and significantly reduces the skill requirements for operators.

[0087] Detailed alarm logs and historical data records can quickly pinpoint the root cause of faults, providing precise support for preventative maintenance.

[0088] This safety operating system effectively ensures the safe operation of the vertical shaft steel pipe multi-functional platform through real-time monitoring by the laser rangefinder 8 and the weighing sensor 9, combined with timely warnings from the first and second alarms, and intelligent control of the control system, preventing safety accidents caused by insufficient working length of the support mechanism 11 or uneven stress on the lifting cable 31.

[0089] This safety operating system, based on real-time data from multiple sensors (laser, weighing) and hard logic interlocks, constructs a multi-layered safety protection system integrating proactive early warning and mandatory intervention. Laser sensor-guided automatic seam alignment replaces manual judgment relying on eyesight and experience, eliminating the problems of subjective nature, inconsistent results, and fatigue-induced missed detections associated with manual inspection. Laser resolution reaches millimeter level, significantly improving seam alignment accuracy, and the standardized algorithm ensures consistent seam alignment. Simultaneously, it enables high-speed automated operation, allowing for continuous 24-hour work and doubling construction efficiency.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
