Description

Technical Field

[0001] The invention relates to the technical field of hydraulic lifting equipment, in particular to hydraulic jacking lifting equipment and a lifting method thereof. Background Art

[0002] In modern industry, with the widespread application of large equipment, the demand for transportation, installation and hoisting of heavy components such as large stators and rotors in power equipment, nuclear power equipment and petrochemical plants is increasing. Such equipment is usually large in size and extremely heavy, and the complexity and safety requirements of its hoisting and sliding operations are significantly increased. In actual projects, traditional hoisting equipment and methods often face technical challenges, including insufficient positioning accuracy, equipment tilting caused by uneven force, unstable tracks during sliding, and poor spatial adaptability. These problems not only increase the complexity and risk of operations, but may also lead to delays in construction progress and equipment damage, which has a significant impact on project quality and construction costs.

[0003] Existing hoisting technology mainly relies on single-function hoisting devices or lifting equipment. Although it can meet the needs of certain specific scenarios, it has obvious deficiencies in multi-scenario adaptability, synchronization control, and precise positioning capabilities. When the hydraulic jacking device is lifted in a large stroke and multiple stages, the equipment is prone to horizontal deflection; in the sliding system, the parallelism and horizontality of the hydraulic jacking tower track beam are not adequately controlled, resulting in unstable equipment operation. In addition, the modular design of traditional hoisting equipment is weak, and it is difficult to quickly adjust to adapt to complex construction environments. Summary of the invention

[0027] 3. When the hydraulic jacking device is operated, the static detection is performed at each stage of lifting to ensure that the self-locking function of the hoisting system and the sealing performance of the hydraulic system are normal. During the sliding process, the precise scale and synchronous adjustment system of the track beam monitors the sliding error in real time and quickly corrects the deviation through fine adjustment. This design ensures the safety and accuracy of the entire hoisting and sliding process.

[0028] 4.

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Please see attached Figure 1 -Attached Figure 4The embodiment of the present invention provides a hydraulic lifting equipment, including a frame body 1, a traveling beam 11 is arranged on the outer wall of the frame body 1, a hydraulic lifting tower body 2 is arranged on the upper surface of the frame body 1, a shoulder beam 3 is fixedly connected to the upper surface of the hydraulic lifting tower body 2, a sling 4 is arranged outside the shoulder beam 3, a stator 5 is slidably connected to the outer wall of the sling 4, a frame lower chord 6 is fixedly connected to the upper outer wall of the frame body 1, a first supporting steel pipe column 7 is arranged inside the frame body 1, and a stator 5 is arranged inside the frame body 1. There is a second supporting steel pipe column 8, and a hydraulic jacking tower track beam 14 is fixedly connected to the upper surface of the frame body 1. The outer wall of the hydraulic jacking tower body 2 is slidably connected to the outer wall of the hydraulic jacking tower track beam 14. A steering beater 12 is arranged in the middle of the frame body 1, a first phase shifter foundation 9 is arranged on the outer wall of the first supporting steel pipe column 7, and a second phase shifter foundation 10 is arranged on the outer wall of the second supporting steel pipe column 8.

[0039] Please see attached Figure 5 -Attached Figure 6 , a hydraulic lifting method, comprising the following steps:

[0040] S1, stator unloading, before unloading, first carry out replacement and compaction treatment according to the laying area of ​​the sliding hydraulic lifting tower track beam 14, and lay iron plates or roadbed boxes in the corresponding transport vehicle walking area and the layout area of ​​the hydraulic lifting tower track beam 14;

[0041] S2, the arrangement of the hydraulic lifting tower track beam 14, when the stator 5 is unloaded, the hydraulic lifting tower track beam 14 is arranged between the BC column and the 4-5 axis, and the arrangement is carried out by a crane, and the center line of the distance between the two hydraulic lifting tower track beams 14 overlaps with the center line of the stator 5;

[0042] S3, hydraulic jacking device arrangement, the hydraulic jacking device is evenly arranged on the hydraulic jacking tower track beam 14, and then the jacking device is arranged;

[0043] S4, stator unloading, stator 5 is transported by transport vehicle from 4-5 axle maintenance channel outside A column to the lifting system area, and lime is used to lay out the line in advance according to the unloading layout diagram to guide the transport vehicle to reverse; the hydraulic jacking device is operated to the designated area, the slings 4 are arranged for stator 5, and all fixed connections between stator 5 and the transport vehicle are removed; the hydraulic jacking device is operated to lift, and the changes in the lifting system, slings 4 and surrounding ground load are observed and confirmed. After the trial lifting is confirmed to be qualified, the transport vehicle is driven out to complete the unloading of stator 5;

[0044] S5, stator steering, using the factory crane to place the roadbed box, turntable and steering beater 12 from bottom to top in sequence on the steering position of the phase regulator stator 5 on the axial center line of the stator 5 in place; the hydraulic jacking device slides to the top of the steering position, and the jacking jack is lowered to place the stator 5 on the steering beater 12. The stator 5 is placed on the steering beater 12 and connected to the two ends of the steering beater 12 through the fall chain. The other end of the fall chain uses the pillar of the factory as an anchor point. The construction personnel pull the fall chains on both sides to rotate the stator 5;

[0045] S6, temporary support arrangement, after the phase regulator stator 5 is unloaded and turned, the hoisting system is dismantled, and when the stator 5 is formally hoisted, the hydraulic jacking tower track beam 14 is symmetrically distributed relative to the axial center line of the stator 5 in place;

[0046] S7 evenly arranges the hydraulic jacking device on the hydraulic jacking tower track beam 14, arranges two shoulder beams 3 above the jacking device, and then arranges the hoisting wire rope saddle. After the hydraulic jacking device and shoulder beam 3 are arranged, the two jacking devices on each track are connected and fixed with a special connecting rod to ensure that the jacking devices move synchronously

[0047] S8. After the hoisting system is assembled, the stator 5 is lifted for the first time. The construction personnel hook the stator 5 lifting lugs to confirm that the wire rope loop is firmly connected, and then test lift the stator 5. When the stator 5 starts to be tested, the hydraulic lifting device slowly lifts it, and observes whether it sinks, whether the metal structure has abnormal deformation, whether the sling 4 has abnormalities, whether the hydraulic system of the hydraulic lifting device has pressure relief, and whether the self-locking device works normally. After confirming that everything is normal, the hydraulic lifting device lifts the stator 5 up and down, confirming that the action is accurate, and the stator 5 is officially lifted after all systems work normally;

[0048] The stator 5 is lifted and slid into place for the second time. The position of the wire rope saddle above the shoulder beam 3 is changed by the crane. The steel sling 4 below the upper shackle of the first lift is removed. The two soft slings are connected to the shackle near the 1 / B column side. The other end is used to hold the inner stator 5 and connect it to the 3 / B column side shackle. After the change work is completed, the crane is driven to the 1-2 axis area, and the hydraulic jacking device is operated to lift the stator 5 for the second time. The current state is maintained. The operator locks the jacking part of the hydraulic jacking device and operates the drive device to move the stator 5 toward the foundation. During the movement, scale lines are drawn on the tracks on both sides, and a special person is assigned to monitor the moving speed of the hydraulic jacking devices on both sides. When there is a deviation in the movement of the jacking devices on both sides, the movement is stopped immediately, and the horizontal jacks on both sides are used for adjustment. After synchronization, the movement continues until the movement stops at the same time just above the foundation. The hydraulic jacking device is operated to slowly descend and the stator 5 falls on the lower half of the stator 5 base in place.

[0049] In S1, the ground elevation after compaction is -1m, and the ground bearing capacity is not less than 11t / m.

[0050] Specifically, after the ground is compacted, during the implementation process, it is necessary to excavate and clean the original foundation, remove the unstable surface soil, and use well-graded crushed stone, sand and gravel or other high-bearing capacity materials for layered filling. The thickness of each layer of filling should be strictly controlled within a reasonable range, such as not exceeding 30cm, and professional compaction equipment such as vibrating rollers or plate compactors should be used to compact the filling materials layer by layer to ensure that the density of the foundation meets the predetermined requirements. During the compaction process, the compaction and density of the foundation need to be monitored at multiple points, and the bearing capacity of the foundation should be tested using standard penetration tests or static load tests to ensure that the design requirements of the ground endurance of 11t / m are met. 2 The final elevation of the ground needs to be calibrated with a precision level or laser measuring instrument to -1m to ensure its flatness and elevation consistency. Through the above steps, the compacted foundation has sufficient bearing capacity and anti-settling ability, providing a stable and safe operating foundation for the subsequent layout of the hydraulic jacking tower track beam and the operation of the lifting equipment, significantly improving the safety and reliability of the entire lifting process.

[0051] In S2, in S2, the crane is arranged with 2 groups of hydraulic jacking tower track beams 14, with a length of 12 meters. When the stator 5 is unloaded, the spacing of the hydraulic jacking tower track beams 14 is 8605mm, the parallelism error of the hydraulic jacking tower track beams 14 on both sides is ≤5mm, and the horizontality error of the hydraulic jacking tower track beams 14 on both sides is ≤5mm.

[0052] Specifically, when using a crane to arrange the hydraulic jacking tower track beam 14, two sets of 12-meter-long hydraulic jacking tower track beams 14 are required to meet the requirements for equipment stability and accuracy during stator unloading and sliding. The spacing of the hydraulic jacking tower track beam 14 is strictly controlled to 8605mm to ensure that the center line of the track is aligned with the center line of the stator, providing accurate guidance for equipment sliding. During the arrangement process, high-precision measuring instruments such as total stations or laser rangefinders are required to monitor the position of the hydraulic jacking tower track beams in real time to ensure that the parallelism error of the hydraulic jacking tower track beams on both sides is controlled within 5mm to prevent guide deviation during sliding. The horizontality of the hydraulic jacking tower track beam must also be strictly calibrated, and the horizontality error is also controlled to ≤5mm to ensure that the hydraulic jacking device is evenly stressed during sliding or jacking, and to avoid equipment shaking or uneven stress due to track tilt. The layout of the hydraulic jacking tower track beam requires the use of precise installation tools and auxiliary support devices to adjust the height difference of the hydraulic jacking tower track beam section by section to ensure that the height difference at the track joint does not exceed the design specification, such as 1.5mm. After the hydraulic jacking tower track beam is arranged, load tests and system function tests are required to verify whether the bearing capacity and layout accuracy of the track meet the requirements of unloading and hoisting operations. This not only improves the installation accuracy of the hydraulic jacking tower track beam, but also provides reliable support and guidance for the slippage of the hydraulic jacking equipment and stator, ensuring the safety and efficiency of the entire hoisting operation.

[0053] The distance between the two jacks on the track beams 14 of the hydraulic jacking towers on both sides of S3 is 3810mm. Two 10-meter-long shoulder beams 3 and four lifting wire rope saddles are arranged above the jacking device. The distance between the saddles is 3600mm. Four Φ108×10.5m wire rope loops are selected for the front and rear lifting points. The wire rope loops are hung on the saddle seats of the shoulder beams 3 and the lifting ears of the phase regulator stator 5, and 8 strands are subjected to force.

[0054] Specifically, hydraulic jacking towers 2 are evenly arranged on the hydraulic jacking tower track beams 14 on both sides, and the spacing between the jacks is strictly controlled to be 3810 mm to optimize the force distribution and improve the stability of the jacking device. Two shoulder pole beams 3 with a length of 10 meters are arranged above the jacking device. The shoulder pole beams 3 serve as a transmission structure for the lifting force. Through their high strength and rigidity design, they effectively disperse the weight of the equipment and improve the overall lifting safety factor;

[0055] Four lifting wire rope saddles are set on the shoulder pole beam 3, and the spacing between the saddles is designed to be 3600mm to adapt to the position of the equipment lifting point and ensure that the wire rope is evenly stressed. Four high-strength wire rope loops of Φ108×10.5m are selected for the front and rear lifting points. The size and strength of the wire rope loops have been strictly calculated and verified to ensure that they can withstand all the loads required for equipment lifting. The wire rope loops are hung on the saddle seat of the shoulder pole beam 16 and the lifting lugs of the phase regulator stator through a special hanging method, forming an 8-strand evenly stressed lifting structure, which not only enhances the safety of the equipment lifting process, but also effectively reduces the risk of equipment shaking and lifting lug damage caused by uneven force in single-point lifting.

[0056] Before the formal operation, the entire lifting system needs to be pre-tightened and loaded to ensure that all connecting parts such as wire rope loops, saddles, shoulder pole beams 3 and lifting eye connection points are in the best working condition, and the force path of the lifting system is clear and free of abnormalities. During the jacking process, the connection between the hydraulic jacking device and the shoulder pole beam 3 is clamped with a special clamp and further fixed by welding blocks to prevent displacement or loosening during the lifting process. The safety, reliability and operability of large-scale equipment lifting are fully considered to ensure that the components are evenly stressed during the equipment lifting process, which significantly improves the efficiency and safety of the lifting operation.

[0057] In S4, in S4, operate the hydraulic lifting device to lift until the distance between the stator 5 and the transport vehicle is 200mm, keep it still for 15 minutes, and after the trial lifting is confirmed to be qualified, continue to lift until the distance between the stator 5 and the transport vehicle is 500mm.

[0058] Specifically, first, slowly operate the hydraulic jacking device to the jacking state, so that the stator is lifted from the transport vehicle plate to a height of 200mm, which can not only effectively release the connection pressure between the transport vehicle plate and the stator, but also ensure that the stator is in a stable and controlled state, which is convenient for subsequent lifting and sliding operations. After jacking to a height of 200mm, the equipment needs to be kept stationary for 15 minutes. During this period, the lifting system is fully inspected and monitored to confirm that the hydraulic system of the hydraulic jacking device has no pressure relief and the self-locking device is working normally. Check whether the lifting equipment and sling 4 are abnormal, such as looseness, slippage or structural deformation. The load-bearing state of the ground and the hydraulic jacking tower track beam area should be observed to ensure that it can withstand the actual load and there is no sinking or cracking.

[0059] After all inspections are qualified, continue to operate the hydraulic jacking device to slowly lift and increase the distance between the stator and the transport vehicle to 500mm. This lifting height is set to provide sufficient safety clearance when the transport vehicle leaves, to avoid collision or other safety hazards to the stator due to uneven ground or displacement caused by the transport vehicle leaving the site. The jacking process requires strict monitoring of the synchronization of the hydraulic jacking device to prevent the stator from tilting during the lifting process. If any horizontal deviation is found, the lifting must be stopped immediately, and the operation can only be continued after the working state of the hydraulic jacking tower 2 is adjusted to restore the horizontal state, which fully guarantees the safety and accuracy of the stator unloading process, and at the same time lays a reliable foundation for subsequent sliding and lifting operations. The step-by-step implementation and real-time monitoring method effectively avoids the risks of deflection, shaking, etc. that may occur during the unloading process, and significantly improves the safety and efficiency of the unloading operation.

[0060] In S5, the construction workers pull the fall chains on both sides to make the stator 5 rotate by 90°. Two fall chains are used with a bearing capacity of 10t.

[0061] Specifically, by arranging the steering device on the axial center line of the stator, including the steering saddle 12, the roadbed box and the turntable and other bearing structures, the stator is stably placed on the steering saddle 12, providing a reliable foundation for subsequent steering operations. In order to achieve a 90° rotation of the stator, the construction personnel connected two fall chains at both ends of the steering saddle 12. The bearing capacity of each fall chain is designed to be 10t, which can fully meet the tension requirements generated during the stator steering process;

[0062] During operation, one end of the fall chain is fixed to the column of the factory building or other stable anchor point, and the other end is connected to the end of the steering beater 12. The construction workers pull the fall chains on both sides synchronously, and gradually apply tension to drive the steering beater 12 and the stator 5 to rotate slowly. The pulling process of the fall chain needs to keep both sides synchronized to prevent the steering beater 12 from being unevenly stressed or the stator from tilting. During the steering process, the rotation angle of the stator needs to be monitored in real time through an angle measuring instrument or a marking line to ensure that the rotation angle reaches 90° and the position is accurate, in order to ensure the safety of the steering process;

[0063] In order to prevent the steering racket 12 from slipping or shifting during the rotation process, it is necessary to set limit devices at the starting and target positions to lock the trajectory range of the racket rotation. After the steering is completed, the supporting structure and connecting parts of the steering racket 12 need to be fully inspected to ensure that there is no deformation or damage during the rotation process before subsequent lifting or sliding operations are performed. During use, not only the precise steering of large equipment is achieved, but the bearing capacity of the fall chain and the synchronous control of the steering process greatly improve the safety and reliability of the operation. It also has the direction adjustment requirements for large stators or similar equipment. The operation is simple and efficient, providing accurate direction guarantee for subsequent lifting operations.

[0064] In S6, the location where the lifting system was dismantled was temporarily supported at the -1 meter layer and the roadbed box was rearranged. The center spacing of the hydraulic jacking tower track beam 14 was 7795mm, the parallelism error of the tracks on both sides was not more than 5mm, the horizontality error was not more than 5mm, the height difference of the track joints was not more than 1.5mm, and the track joint gap was not more than 1.5mm. The hydraulic jacking tower track beam 14 was composed of 2 groups of box beams, of which 1 group of box beams on both sides of the stator 5 base was arranged on the stator 5 base, and the other group of box beams was arranged on the support columns. The 2 groups of box beams at other positions were arranged on the support columns.

[0065] Specifically, the arrangement of the hydraulic jacking tower track beam 14 is a key link in this step, and the center spacing is designed to be 7795mm to ensure that the hydraulic jacking tower track beam 14 can accurately align the operating path required for stator sliding and lifting. During the arrangement process, the parallelism error of the hydraulic jacking tower track beams 14 on both sides is strictly controlled to not exceed 5mm, and the horizontality error is also controlled to not exceed 5mm to ensure that the hydraulic jacking device runs smoothly on the track with good synchronization. In addition, the height difference of the joints of the hydraulic jacking tower track beam 14 shall not exceed 1.5mm, and the joint gap must be strictly controlled to not exceed 1.5mm to ensure the continuity of the track and the smooth transition of the hydraulic jacking device during sliding;

[0066] The hydraulic lifting tower track beam 14 is composed of two groups of box beams, and each group of box beams is fixed by high-strength connectors to ensure that its load-bearing capacity meets the high-strength requirements required during equipment lifting and sliding. In the specific layout process, one group of box beams on both sides of the stator base is directly arranged on the stator base to bear the weight of the stator and provide stable support; the other group of box beams is arranged on the support columns to evenly distribute the load and enhance the overall rigidity of the track. For the layout of the hydraulic lifting tower track beam 14 in other locations, both groups of box beams need to be arranged on the support columns to ensure the overall stability and deformation resistance of the track system;

[0067] After the arrangement is completed, the hydraulic jacking tower track beam 14 and its supporting structure are comprehensively inspected, including the position, horizontality, parallelism and joint connection quality, to ensure that the hydraulic jacking tower track beam 14 system meets the design specifications and lifting operation requirements. Through the above arrangement, the hydraulic jacking tower track beam 14 system can provide precise guidance and stable support for stator sliding and lifting, avoiding the risk of equipment shaking or sliding deviation caused by uneven tracks or excessive errors, significantly improving the safety and efficiency of lifting operations, and laying a solid foundation for subsequent operations.

[0068] In S7, the distance between the two jacks on the track beam 14 of the hydraulic jacking tower is 3810mm, the length of the shoulder pole is 10 meters, and there are 4 lifting wire rope saddles, of which the distance between the saddles is 3600mm. The left shoulder pole beam 3 is equipped with 10.5-meter wire rope loop + 85t shackle + 5-meter Φ98×5-meter wire rope loop + 85t shackle + 5-meter Φ98×5-meter wire rope loop, and the right shoulder pole beam 3 is equipped with 10.5-meter wire rope loop + 85t shackle + 11.5-meter wire rope loop. In order to prevent the pull rod from being deformed by force during walking, two 5t fall chains are used to tighten it.

[0069] Specifically, the spacing between the hydraulic jacking towers 2 arranged on the hydraulic jacking tower track beam 14 is designed to be 3810 mm. This spacing has been verified by calculation and can effectively disperse the concentrated load during stator hoisting, avoid excessive local stress, and maintain the mechanical balance of the hydraulic jacking device during operation;

[0070] The length of the shoulder pole beam 3 is 10 meters. As an important load-bearing structure during the lifting process, four lifting wire rope saddles are evenly arranged on both sides, and the spacing between the saddles is 3600mm. The design of the saddle spacing not only matches the lifting point position of the equipment, but also ensures that the wire rope is evenly stressed during the lifting process, avoiding shaking or deviation of the lifting due to uneven stress. In order to meet the lifting requirements, the left shoulder pole beam 3 is equipped with a 10.5-meter wire rope loop, an 85t shackle, and two sets of 5-meter Φ98×5-meter wire rope loop combination connectors. These connectors are all of high strength and durability and can withstand the large loads generated during the lifting process. The right shoulder pole beam 3 is equipped with a 10.5-meter wire rope loop, an 85t shackle, and a set of 11.5-meter wire rope loops, which are suitable for situations where the weight distribution of the equipment is not completely symmetrical, and can maintain the horizontality during the lifting process by adjusting wire rope loops of different lengths;

[0071] In order to prevent the tie rod from being deformed due to stress during the walking process, the tie rods between the hydraulic jacking devices on the track beam of the hydraulic jacking tower are additionally reinforced, and two 5t fall chains are used to tighten the tie rods. The function of the fall chain is to provide additional restraint force to prevent the tie rods from being deformed due to the asynchrony of the hydraulic jacking device or external vibration, and further ensure the stability of the equipment during sliding or lifting operations;

[0072] The precise spacing of the hydraulic lifting devices, the optimized force design of the shoulder beam 3, and the multi-level reinforcement measures of the tie rods provide the hoisting system with sufficient rigidity and stability. The configuration and connection between each component have been strictly checked for strength to ensure that the equipment is evenly stressed and highly safe during the hoisting operation. At the same time, the use of chain reinforcement further enhances the risk resistance during hoisting and sliding operations, provides reliable technical support for the hoisting and operation of large equipment, and significantly improves the overall operation efficiency and accuracy.

[0073] In S8, the height of the hydraulic jacking device in the first stator 5 lifting is 4616mm. During the slow lifting of the hydraulic jacking device, the stator 5 stops lifting when it is about 200mm away from the steering beater 12 and stays still for 15 minutes. The stator 5 is raised and lowered twice, 100mm each time. The wire rope saddles are located on both sides of the center line of the stator 5 with a spacing of 3090mm. The length of the soft sling is 11 meters. The height of the hydraulic jacking device for the second lifting is 3886mm. When the lower edge of the stator 5 exceeds the 5m base platform by about 800mm, the jacking is stopped. At this time, the height of the hydraulic jacking device is 8858mm, the net space between the jacking device and the roof above is 1886mm, and the net space with the left and right sides is 2950mm. The stopping deviation of the jacking devices on both sides is 100mm, and the basic sliding distance of the stator 5 is 20000mm. Among them, the height of the hydraulic jacking device in the slow descent is 7268mm.

[0074] Specifically, the horizontality of the stator must be monitored during the jacking process. If any deviation is found, it must be stopped immediately. The jacking can be continued only after the stator is adjusted to the horizontal level by a single jacking device. Due to the difference in the length of the sling, the lifting height difference of the two shoulder beams 3 needs to be maintained at about 150mm. When the stator is lifted 1500mm, the jacking is stopped, and the steering racket 12 under the stator is pulled away by a loader. Four 1300mm high steel piers are placed at the stress position under the top and bottom rackets by manpower, and the hydraulic jacking device is operated to descend, and the stator is dropped on the steel piers;

[0075] During the first stator lifting, the initial height of the hydraulic jacking device is 4616mm, and the stator is gradually lifted from the steering beater 12 through a slow jacking operation. When the stator is about 200mm away from the steering beater 12, the jacking is stopped immediately and remains stationary for 15 minutes. During this period, a comprehensive inspection of the hydraulic jacking device, sling 4 and stator 5 is carried out, including the stability of the hydraulic system, the uniformity of the force of the lifting system and the deformation of the metal structural parts, to ensure that all components operate normally and there are no safety hazards. Subsequently, a trial lifting operation is performed, and the stator completes two lifts and lowerings, each time at a height of 100mm. This process verifies the motion accuracy of the hydraulic jacking device and the reliability of the lifting system, providing guarantees for the subsequent formal lifting;

[0076] The arrangement positions of the wire rope saddles are distributed on both sides of the center line of the stator, and the spacing is designed to be 3090mm to ensure uniform force during the hoisting process. The length of the soft sling used in the hoisting system is 11 meters, which matches the structural height of the hoisting system and equipment. It can effectively alleviate local stress concentration and further improve the safety and stability of the hoisting operation. During the second lifting process, the height of the hydraulic jacking device was adjusted to 3886mm, and then slowly lifted. When the lower edge of the stator exceeded the 5-meter base platform by about 800mm, the lifting was stopped. At this time, the height of the hydraulic jacking device reached 8858mm. In this state, the net space between the jack and the roof above is 1886mm, and the net space with the left and right sides is 2950mm, which fully meets the requirements of the hoisting operation for the net space and avoids equipment collision or operation risks caused by insufficient space.

[0077] During the lifting and sliding process, the synchronization of the hydraulic lifting devices on both sides is strictly controlled, and the deviation of the stop position does not exceed 100mm. If the deviation reaches the critical value, stop the operation immediately and restore the synchronization through fine-tuning measures to ensure that the stator is in a horizontal state. During the sliding process, the sliding distance of the stator foundation is designed to be 20000mm, and there are precise scale lines on the sliding track to facilitate real-time monitoring of the sliding distance and positioning accuracy. After sliding to the top of the stator foundation, slowly operate the hydraulic lifting device to descend, and the height is finally adjusted to 7268mm to ensure that the stator falls smoothly and safely on the foundation. The multi-stage precise lifting and sliding operation of the stator, the height adjustment of the hydraulic lifting device, the saddle arrangement and the reasonable selection of the soft sling ensure the reliability of the lifting system. The strict synchronization control and space reservation measures effectively reduce the risks that may occur during the lifting and sliding process, significantly improve the efficiency, accuracy and safety of the lifting of large equipment, and provide reliable technical support for the installation and positioning of complex equipment.
