Description

Technical Field

[0001] The invention relates to the technical field of hydropower engineering, in particular to an auxiliary lifting device for construction of a pumped storage power station. Background Art

[0002] During the construction of a pumped storage power station, the installation of pressure pipes is crucial. Pressure pipes are key hydraulic transmission channels connecting the upper and lower reservoirs and the power generation equipment. During the operation of a pumped storage power station, water needs to circulate between the upper and lower reservoirs to store and release electrical energy. Pressure pipes are responsible for stably transporting water at high pressure, and their transport efficiency and stability directly affect the power generation and operational reliability of the entire power station.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments 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.

[0020] Embodiment, a pumped storage power station construction auxiliary lifting device, please refer to the attached Figure 1 -Attached Figure 3The device includes a bottom column 1, which serves as the basic support structure of the entire lifting device. It provides a stable installation foundation for the support column 2 to ensure that the lifting device can stand reliably under different construction site conditions. The top of the bottom column 1 is rotatably connected to the support column 2. The push connection method allows the support column 2 to flexibly rotate relative to the bottom column 1. During the lifting operation, the lifting direction can be easily adjusted to meet the lifting requirements of pipes or heavy objects in different positions. An adjustment component is installed on the outer wall of the support column 2. The adjustment component can accurately control the rotation angle of the support column 2 to achieve fine-tuning of the lifting direction, avoid installation difficulties or collision accidents caused by deviation in the lifting direction, and ensure the smooth progress of the construction. The top of the support column 2 is fixedly connected to a support plate 4, which provides a stable installation platform for the upper structure of the lifting device. It can evenly disperse the weight and force from components such as the hydraulic cylinder 5, the fixed arm 6, and the take-up roller 8 to prevent local excessive force from causing structural damage. The bottom of the support plate 4 is rotatably connected with a hydraulic cylinder 5. The hydraulic cylinder 5 is one of the power sources of the lifting device. Its rotational connection mode enables it to adjust the direction of the force within a certain angle range. During the lifting process, according to different lifting heights and angle requirements, the hydraulic cylinder 5 can flexibly change the posture of the fixed arm 6 through its own extension and rotation, thereby realizing accurate control of the position of the hook 11. The output end of the hydraulic cylinder 5 is rotatably connected with the fixed arm 6. This rotational connection enables the fixed arm 6 to rotate relative to the hydraulic cylinder 5, further increasing the flexibility of the lifting device. The interior of the fixed arm 6 is slidably connected with an extension arm 7 along the length direction. The sliding connection mode of the extension arm 7 and the fixed arm 6 can realize the adjustment of the lifting radius. In different construction scenarios, according to the different distances between the pipe or heavy object to be lifted and the lifting device, the extension arm 7 can slide out or retract in the fixed arm 6 to flexibly adjust the lifting radius. The top of the support plate 4 is fixedly connected with a first motor 9. During the lifting operation, the reeling and unwinding actions of the reeling roller 8 are controlled by the forward and reverse rotation of the first motor 9, thereby realizing the rise and fall of the hook 11. The output end of the first motor 9 is fixedly connected to a take-up roller 8. During the lifting process, the take-up roller 8 converts the rotational motion of the motor into the linear motion of the steel cable through linkage with the first motor 9, thereby driving the hook 11 to rise or fall. The outer wall of the take-up roller 8 is sleeved with a steel cable, which can bear the weight of the pipe or heavy object and safely hang it on the hook 11. During the lifting process, the steel cable expands and contracts as the take-up roller 8 rotates, and the lifting force is evenly distributed on its own structure to ensure that it will not break due to excessive local force. The end of the steel cable away from the take-up roller 8 is fixedly connected to the hook 11. The hook 11 is a component directly connected to the lifting object. Its shape and structural design need to adapt to pipes or heavy objects of different shapes and sizes to ensure the firmness and reliability of the connection. An auxiliary component is provided at the bottom of the hook 11, which can provide multi-faceted protection and auxiliary operations for the pipeline during the lifting process; Please refer to the attached Figure 1 and attached Figure 3 The auxiliary components include a balance beam 12, which is connected to the hook 11 through a steel cable. The balance beam 12 plays a key balancing role in the lifting process. It evenly distributes the lifting force to different parts of the pipeline through the steel cable connected to the hook 11. Two sliding columns 13 are slidably connected to the middle of the balance beam 12. The sliding connection between the sliding column 13 and the balance beam 12 enables it to move up and down relative to the balance beam 12. A limit block 14 is fixedly connected to the top of the sliding column 13. The function of the limit block 14 is to prevent the sliding column 13 from escaping from the balance beam 12 during the sliding process. A mounting plate 15 is fixedly connected to the bottom of the sliding column 13. The mounting plate 15 is a component that directly contacts the pipeline and performs fixing and related operations. It provides an installation foundation for the fixing component, the transmission component and the cleaning component. A fixing component is arranged inside the mounting plate 15. The fixing component can firmly fix the pipeline on the mounting plate 15 to prevent the pipeline from slipping or displacement during the lifting process. A transmission component is arranged inside the mounting plate 15. The transmission component plays a role in force transmission and conversion in the lifting device. It can convert the linear motion of the slide plate 19 into the rotational motion of other parts, drive the third gear 29 in the cleaning assembly to rotate, thereby realizing the cleaning function of the pipeline. The outer walls on both sides of the mounting plate 15 are provided with cleaning assemblies, which can clean the outer wall of the pipeline during the lifting process. In the construction environment of a pumped storage power station, the pressure pipeline may be contaminated with dust, soil or other impurities. If these impurities are not cleaned in time, they may affect the installation quality and subsequent operation performance of the pipeline.

[0021] Please refer to the attached Figure 3 -Attached Figure 5The fixing assembly includes a slide bar 18, which is fixedly connected to the inside of the mounting plate 15. The slide bar 18 provides guidance and support for other components in the fixing assembly. It is fixed inside the mounting plate 15 to ensure that the slide plate 19 can slide stably along the slide bar 18, making the structure of the entire fixing assembly more stable. Two slide plates 19 are slidably connected to the outer wall of the slide bar 18. When the pipeline needs to be fixed, the two slide plates 19 can slide toward each other through external force or the drive of the transmission assembly, driving the arc plate 21 close to the outer wall of the pipeline to achieve clamping of the pipeline. The top of the slide plate 19 is rotatably connected to a connecting rod 20. When the balance beam 12 is slightly displaced by the gravity of the pipeline or other external forces, the connecting rod 20 will convert this displacement into the sliding movement of the slide plate 19 on the slide bar 18. The end of the connecting rod 20 away from the slide plate 19 is rotatably connected to the bottom of the balance beam 12. An arc plate 21 is fixedly connected to the bottom of 19, and the arc plate 21 directly contacts the outer wall of the pipe. Its arc shape design can better fit the surface of the circular pipe, increase the contact area, and improve the friction. A first spring 23 is sleeved on the outer wall of the slide bar 18. The first spring 23 plays a reset role in the fixing component. When the slide plate 19 slides along the slide bar 18, the first spring 23 is squeezed, so that the first spring 23 stores potential energy. When it is transferred to the specified position, the first spring 23 releases the potential energy, thereby no longer fixing the pipe.

[0022] Please refer to the attached Figure 5 and attached Figure 6 The transmission assembly includes a rotating shaft 24 and a rack plate 27. The outer wall of the rotating shaft 24 is rotatably connected to the inner wall of the mounting plate 15. The rotating shaft 24 is a key rotating component in the transmission assembly. The rotation connection method between the rotating shaft 24 and the inner wall of the mounting plate 15 ensures that it can rotate flexibly in the mounting plate 15. During the lifting process, the rotating shaft 24 receives the power from the movement of the slide plate 19 and transmits it to other gear components, thereby driving the cleaning assembly to work. A first gear 25 is fixedly connected to the middle of the outer wall of the rotating shaft 24. The first gear 25 plays the role of intermediate transmission in the transmission assembly. It meshes with the rack plate 27. When the rack plate 27 moves with the slide plate 19, it will drive the first gear 25 to rotate. The left and right ends of the outer wall of the rotating shaft 24 are fixedly connected to the second gear 26. The second gear 26 further transmits the rotational motion of the rotating shaft 24 to the third gear 29 in the cleaning assembly. The design of being fixedly connected to the left and right ends of the outer wall of the rotating shaft 24 enables the cleaning components on the left and right sides of the mounting plate 15 to be driven to work at the same time, thereby improving the cleaning efficiency. The rack plate 27 is fixedly connected to the outer wall of one of the slide plates 19. The rack plate 27 is a key component for converting the linear motion of the slide plate 19 into the rotational motion of the gear. The fixed connection between the rack plate 27 and the slide plate 19 ensures the synchronous motion of the two. When the slide plate 19 slides on the slide bar 18, the rack plate 27 will move accordingly, and through meshing with the first gear 25, the linear motion will be converted into the rotational motion of the first gear 25, thereby driving the entire transmission assembly to work.

[0023] Please refer to the attached Figure 7 and attached Figure 8 The cleaning assembly includes a fixed plate 28, which is fixedly connected to the outer walls on the left and right sides of the mounting plate 15. The fixed plate 28 provides an installation foundation and support for other components in the cleaning assembly. It is fixed to the outer walls on the left and right sides of the mounting plate 15 to ensure that the third gear 29, the limit column 30, the cleaning plate 31 and the brush 32 can be stably installed and work. The bottom of the two fixed plates 28 on the opposite side is rotatably connected with the third gear 29, and the third gear 29 plays a core transmission role in the cleaning assembly. It meshes with the second gear 26 and rotates by receiving power from the transmission assembly. The way in which it is rotatably connected to the bottom of the fixed plate 28 enables it to rotate flexibly in a relatively stable plane, effectively transmitting the incoming rotational power to the limit column 30 and the cleaning plate 31, driving the brush 32 on the cleaning plate 31 to wipe and clean the inner wall of the pipeline, and the inner wall of the third gear 29 is fixedly connected with a plurality of limit columns 30, and the limit columns 30 provide guidance and restriction for the movement of the cleaning plate 31. It is fixed on the inner wall of the third gear 29. When the third gear 29 rotates, the limiting column 30 moves in a circular motion. The cleaning plate 31 is slidably connected to the outer wall of the limiting column 30. Through the guidance of the limiting column 30, the cleaning plate 31 can only move in a specific direction and range to ensure that it will not deviate from the predetermined trajectory during the cleaning process. The outer wall of the limiting column 30 is slidably connected with the cleaning plate 31, and the cleaning plate 31 is a component that directly contacts the outer wall of the pipeline for cleaning. It can move in a circular motion with the third gear 29 when the third gear 29 rotates through a sliding connection with the limiting column 30. The top of the cleaning plate 31 away from the limiting column 30 is fixedly connected with a brush 32. The brush 32 is a key part for realizing the cleaning function, which can effectively absorb and remove dust and ensure that the outer wall of the pipeline is well cleaned during the lifting process. The outer wall of the limiting column 30 is provided with a second spring 33, and the second spring 33 plays a buffering and regulating role in the cleaning assembly. When the cleaning plate 31 slides on the limiting column 30, the second spring 33 will be compressed or stretched. During the cleaning process, it can buffer the impact force generated when the cleaning plate 31 contacts the outer wall of the pipeline, preventing the pipeline surface from being damaged or the cleaning components from being damaged due to rigid collision.

[0024] Please refer to the attached Figure 2The adjustment component includes a worm gear 3 and a second motor 34, which are both fixedly connected to the outer wall of the support column 2 to form a compact and stable structure. The second motor 34, as a power source, can output torque, and the worm gear 3 rotates under the action of the torque, thereby driving the support column 2 to achieve precise angle adjustment. The output end of the second motor 34 is fixedly connected to a worm 10, and the worm gear 3 and the worm 10 are meshed. Through the meshing transmission of the worm 10 and the worm gear 3, the support column 2 can achieve a corresponding small angle rotation, meeting the requirements for the position accuracy of the lifting position of heavy objects such as pressure pipes during the construction of pumped storage power stations.

[0025] Please refer to the attached Figure 1 The end of the fixed arm 6 away from the extension arm 7 is rotatably connected to the middle of the support plate 4. During the lifting process, the fixed arm 6 can adjust its angle within a certain range according to the position of the pipeline and the requirements of the lifting path, so that the hook 11 can reach the lifting point of the pipeline more accurately, which is convenient for the hook operation of the pipeline. A plurality of guide frames are fixedly connected to the top of the fixed arm 6. The function of the guide frame is to guide and limit the steel cable. During the lifting process, the steel cable retracts and contracts with the rotation of the take-up roller 8. The guide frame can ensure that the steel cable moves along the predetermined path to avoid the problem of the steel cable being entangled or jumping during the movement.

[0026] Please refer to the attached Figure 3 -Attached Figure 5 The inner wall of the arc plate 21 is fixedly connected with a corrugated plate 22, which can increase the friction and contact stability between the arc plate 21 and the outer wall of the pipe. Its corrugated structure can better adapt to the slight unevenness of the outer wall of the pipe, so that the arc plate 21 can fit the pipe surface more closely when clamping the pipe, thereby improving the fixing effect. One end of the first spring 23 is fixedly connected to the inner wall of the mounting plate 15, and the other end of the first spring 23 is fixedly connected to the outer wall of the slide bar 18. When the slide plate 19 drives the arc plate 21 to clamp or release the pipe, the first spring 23 is compressed or stretched between the slide bar 18 and the mounting plate 15. The fixed connection at both ends ensures that the spring force can effectively act on the entire fixing assembly.

[0027] Please refer to the attached Figure 5 -Attached Figure 7 , the rack plate 27 and the first gear 25 are meshed, and the second gear 26 and the third gear 29 are meshed. When the slide plate 19 moves, the rack plate 27 drives the first gear 25 to rotate, and the first gear 25 drives the second gear 26 to rotate through the rotating shaft 24, thereby driving the third gear 29 to rotate, and the gear ratio of the third gear 29 to the second gear 26 is 1:3, so that the rotation speed of the third gear 29 is relatively slow and the torque is relatively large. In the cleaning assembly, such a design can make the movement speed of the cleaning plate 31 on the limit column 30 moderate, which can not only ensure the cleaning effect, but also avoid damage to the outer wall of the pipeline due to excessive movement speed.

[0028] Please refer to the attached Figure 8 One end of the second spring 33 is fixedly connected to the outer wall of the cleaning plate 31, and the other end of the second spring 33 is fixedly connected to the inner wall of the third gear 29. When the third gear 29 rotates to drive the cleaning plate 31 to move, when the cleaning plate 31 encounters the unevenness or greater resistance of the outer wall of the pipeline, the second spring 33 will be compressed or stretched, thereby buffering the impact force between the cleaning plate 31 and the outer wall of the pipeline, protecting the pipeline surface and the cleaning components from damage. At the same time, the second spring 33 can automatically adjust the position and pressure of the cleaning plate 31 according to the actual situation of the outer wall of the pipeline, so that the brush 32 can always maintain a good contact state with the outer wall of the pipeline, improve the uniformity and thoroughness of cleaning, and ensure that the outer wall of the pipeline can be fully and effectively cleaned during the lifting process.

[0029] Please refer to the attached Figure 3 -Attached Figure 5 A plurality of connecting rods 16 are fixedly connected to the bottom of the mounting plate 15, and a bottom plate 17 is fixedly connected between the plurality of connecting rods 16. The connecting rods 16 and the bottom plate 17 cooperate with each other, so that during the transportation of the pipeline, the mounting plate 15 can be supported, so that the fixing components inside the mounting plate 15 can better fix the pipeline.

[0030] Working principle: During the construction of a pumped-storage power station, it is necessary to transfer the construction pipeline to a designated location. When the pipeline needs to be transferred, the second motor 34 is controlled to start. When the second motor 34 is started, it will rotate. The rotation generated by the second motor 34 will drive the worm 10 to rotate. The rotation of the worm 10 will drive the worm wheel 3 to rotate through engagement with the worm wheel 3, thereby driving the support column 2 to rotate, so that the position of the lifting device is adjusted to above the construction pipeline.

[0031] Subsequently, the second motor 34 is rotated and controls the first motor 9 to rotate. The first motor 9 rotates to rotate the take-up roller 8, lower the steel cable wrapped around the take-up roller 8, slide the hook 11 downward, and place the mounting plate 15 above the construction pipeline.

[0032] Furthermore, the lifting function is realized by controlling the start of the first motor 9 again. During the lifting process, the steel cable will pull the hook 11 to slide, and further drive the balance beam 12 to slide. When the balance beam 12 slides, it will slide along the surface of the sliding column 13. At the same time, it will also drive the connecting rod 20 to rotate under the action of the gravity of the mounting plate 15. When the connecting rod 20 rotates, it will drive the two slides 19 to slide in opposite directions, and further drive the arc plate 21 at the bottom of the slide 19 to slide, thereby achieving the effect of fixing the construction pipeline.

[0033] When the arc plate 21 slides, the rack plate 27 is also driven to slide. When the rack plate 27 slides, the meshing with the first gear 25 drives the first gear 25 to rotate, and further drives the rotating shaft 24 to rotate, so that the two second gears 26 rotate. When the second gear 26 rotates, it drives the third gear 29 to rotate through the meshing with the third gear 29, and further drives the limiting column 30 on the surface of the third gear 29 to rotate, so as to rotate and clean the construction pipeline connection.
