Description

[0002] In the construction process of a pumped storage power station, the installation of a pressure pipeline is crucial. The pressure pipeline is a key hydraulic transmission channel connecting an upper reservoir and a lower reservoir and a power generation device.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0029] Embodiment, a hoisting device for construction of pumped storage power station, please refer to the attached Figure 1 -attached Figure 3The device comprises a bottom column 1 as the basic support structure of the whole lifting device, which provides a stable mounting base for the support column 2, ensuring that the lifting device can stand reliably under different construction site conditions. The top of the bottom column 1 is rotatably connected with the support column 2, and the push connection mode enables the support column 2 to rotate flexibly relative to the bottom column 1, which can conveniently adjust the lifting direction during lifting operation, and adapt to the lifting requirements of pipes or heavy objects at different positions. The outer wall of the support column 2 is provided with an adjusting assembly, which can accurately control the rotation angle of the support column 2, realize the fine adjustment of the lifting direction, avoid the installation difficulty or collision accident caused by the deviation of the lifting direction, and ensure the smooth construction. The top of the support column 2 is fixedly connected with a support plate 4, which provides a stable mounting platform for the upper structure of the lifting device. It can uniformly distribute the weight and force from the hydraulic cylinder 5, fixed arm 6, take-up roller 8 and other components, preventing local overloading and structural damage. The bottom of the support plate 4 is rotatably connected with the hydraulic cylinder 5, which is one of the power sources of the lifting device, and the rotary connection mode enables it to adjust the force direction within a certain angle range. During lifting, according to different lifting height and angle requirements, the hydraulic cylinder 5 can change the posture of the fixed arm 6 flexibly through its own extension and rotation, so as to realize the 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, which can rotate relative to the hydraulic cylinder 5, further increasing the flexibility of the lifting device. The inside of the fixed arm 6 is slidably connected with an extension arm 7 along the length direction, and the sliding connection between the extension arm 7 and the fixed arm 6 can realize the adjustment of the lifting radius. In different construction scenes, according to the different distances between the pipes or heavy objects to be lifted and the lifting device, the extension arm 7 can slide out or retract in the fixed arm 6, flexibly adjusting the lifting radius. The top of the support plate 4 is fixedly connected with a first motor 9, which controls the take-up and pay-off actions of the take-up roller 8 through forward and reverse rotation during lifting, thereby realizing the rising and falling of the hook 11. The output end of the first motor 9 is fixedly connected with the take-up roller 8, which converts the rotary motion of the motor into the linear motion of the steel cable during lifting, thereby driving the hook 11 to rise or fall. The take-up roller 8 is sleeved with a steel cable outside the wall, which can bear the weight of the pipes or heavy objects and safely suspend them on the hook 11. During lifting, the steel cable stretches and contracts with the rotation of the take-up roller 8, evenly distributing the lifting force on its own structure, ensuring that it will not break due to local overloading. The end of the steel cable away from the take-up roller 8 is fixedly connected with the hook 11, which is directly connected with the lifting object. Its shape and structure design should adapt to pipes or heavy objects of different shapes and sizes to ensure the firmness and reliability of the connection. The bottom of the hook 11 is provided with an auxiliary assembly, which can protect and assist the pipe during lifting in multiple ways;

[0030] Please refer to the attached Figure 1 and the attached Figure 3 The auxiliary assembly includes a balance beam 12 connected with the hook 11 through a steel cable. The balance beam 12 plays a key balancing role in the lifting process. It distributes the lifting force evenly on different parts of the pipeline through the steel cable connected with the hook 11. The middle part of the balance beam 12 is slidingly connected with two slide columns 13. The sliding connection of the slide columns 13 with the balance beam 12 enables them to move up and down relative to the balance beam 12. The top of the slide column 13 is fixedly connected with a limiting block 14, which prevents the slide column 13 from falling out of the balance beam 12 during sliding. The bottom of the slide column 13 is fixedly connected with a mounting plate 15, which is the component that directly contacts and fixes the pipeline and performs related operations. It provides a mounting base for the fixing assembly, the transmission assembly and the cleaning assembly. The mounting plate 15 is internally provided with a fixing assembly, which can firmly fix the pipeline on the mounting plate 15, preventing the pipeline from falling or shifting during lifting. The mounting plate 15 is internally provided with a transmission assembly, which 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 components, drive the third gear 29 in the cleaning assembly to rotate, and thus realize the cleaning function of the pipeline. The left and right outer walls of the mounting plate 15 are both provided with a cleaning assembly, which can clean the outer wall of the pipeline during lifting. In the construction environment of pumped storage power stations, 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.

[0031] Please refer to the attached Figure 3 - the attached Figure 5The fixed assembly includes a sliding rod 18 fixedly connected inside the mounting plate 15, which provides guidance and support for other components in the fixed assembly. It is fixed inside the mounting plate 15 to ensure that the sliding plate 19 can slide stably along the sliding rod 18, making the structure of the entire fixed assembly more stable. The outer wall of the sliding rod 18 is slidingly connected with two sliding plates 19. When it is necessary to fix the pipeline, through external force or the driving of the transmission assembly, the two sliding plates 19 can slide towards each other, driving the arc-shaped plate 21 to approach the outer wall of the pipeline, realizing the clamping of the pipeline. The top of the sliding plate 19 is rotatably connected with a connecting rod 20. When the balance beam 12 is slightly displaced due to the gravity of the pipeline or other external forces, the connecting rod 20 will convert this displacement into sliding movement of the sliding plate 19 on the sliding rod 18. The end of the connecting rod 20 away from the sliding plate 19 is rotatably connected to the bottom of the balance beam 12. The bottom of the sliding plate 19 is fixedly connected with the arc-shaped plate 21, which directly contacts the outer wall of the pipeline. Its arc-shaped design can better fit the surface of the circular pipeline, increasing the contact area and improving the friction. The outer wall of the sliding rod 18 is sleeved with a first spring 23, which plays a resetting role in the fixed assembly. When the sliding plate 19 slides along the sliding rod 18, it will press the first spring 23, causing the first spring 23 to store potential energy. When the displacement is transferred to the designated position, the first spring 23 will release the potential energy, thus no longer fixing the pipeline.

[0032] 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, as a key rotating component in the transmission assembly, can rotate flexibly inside the mounting plate 15 due to its rotatable connection with the inner wall of the mounting plate 15. During the lifting process, the rotating shaft 24 receives power from the movement of the sliding plate 19 and transmits it to other gear components, thereby driving the cleaning assembly to work. The outer wall of the rotating shaft 24 is fixedly connected with a first gear 25, which plays an intermediate transmission role in the transmission assembly. It is engaged with the rack plate 27, and when the rack plate 27 moves with the sliding plate 19, it will drive the first gear 25 to rotate. The outer wall of the rotating shaft 24 is fixedly connected with a second gear 26 at both ends. The second gear 26 further transmits the rotating motion of the rotating shaft 24 to the third gear 29 in the cleaning assembly. Its design of being fixedly connected at both ends of the outer wall of the rotating shaft 24 allows it to drive the cleaning assemblies on both sides of the mounting plate 15 to work simultaneously, improving cleaning efficiency. The rack plate 27 is fixedly connected to the outer wall of one of the sliding plates 19. As a key component for converting linear motion of the sliding plate 19 into rotational motion of the gear, the rack plate 27 ensures synchronous movement with the sliding plate 19. When the sliding plate 19 slides on the sliding rod 18, the rack plate 27 will move with it, converting linear motion into rotational motion of the first gear 25 through engagement with the first gear 25, thereby driving the entire transmission assembly to work.

[0033] Please refer to the attached Figure 7 and attached Figure 8 The cleaning assembly includes a fixed plate 28 fixedly connected to the outer walls on both sides of the mounting plate 15, which provides a mounting base and support for other components in the cleaning assembly. It is fixed to the outer walls on both sides of the mounting plate 15 to ensure that components such as the third gear 29, the limiting column 30, the cleaning plate 31 and the brush 32 can be stably installed and work. The two fixed plates 28 are rotatably connected to the third gear 29 on the bottom of the opposite side, which plays a core transmission role in the cleaning assembly. It meshes with the second gear 26 to receive power from the transmission assembly and rotate. The way it is rotatably connected to the bottom of the fixed plate 28 allows it to rotate flexibly in a relatively stable plane, effectively transmitting the incoming rotational power to the limiting 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 pipe. The third gear 29 has a plurality of limiting columns 30 fixedly connected to the inner wall, which provides guidance and limitation for the movement of the cleaning plate 31. It is fixed to the inner wall of the third gear 29, and 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, and through the guidance of the limiting column 30, the cleaning plate 31 can only move in a specific direction and range, ensuring that it does not deviate from the predetermined trajectory during cleaning. The limiting column 30 has a cleaning plate 31 slidably connected to the outer wall, which is the component that directly contacts the outer wall of the pipe for cleaning. It can move in a circular motion with the third gear 29 through the sliding connection with the limiting column 30, and the cleaning plate 31 has a brush 32 fixedly connected to the top of the side away from the limiting column 30, which is the key part to realize the cleaning function and can effectively adsorb and remove dust, ensuring that the outer wall of the pipe is well cleaned during lifting. The limiting column 30 has a second spring 33 sleeved on the outer wall, which plays a buffering and adjusting 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 cleaning, it can buffer the impact force generated when the cleaning plate 31 contacts the outer wall of the pipe, preventing damage to the pipe surface or the cleaning assembly due to rigid impact.

[0034] Please refer to the attached Figure 2The adjusting assembly comprises a worm gear 3 and a second motor 34, both of which are fixedly connected to the outer wall of the support column 2, forming a compact and stable structure. The second motor 34 serves as a power source and can output torque, while the worm gear 3 rotates under the action of the torque, thereby driving the support column 2 to realize precise angle adjustment. The output end of the second motor 34 is fixedly connected with a worm 10, and the worm gear 3 and the worm 10 are engaged. Through the engagement transmission between the worm 10 and the worm gear 3, the support column 2 can realize corresponding small-angle rotation, meeting the requirements for the lifting position precision of heavy objects such as pressure pipes in the construction of pumped storage power stations.

[0035] Please refer to the accompanying drawings Figure 1 One end of the fixed arm 6 away from the extension arm 7 is rotatably connected to the middle part 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 pipe and the requirements of the lifting path, so that the hook 11 can more accurately reach above the lifting point of the pipe, facilitating the hooking operation of the pipe. The top of the fixed arm 6 is fixedly connected with multiple guide frames, which serve to guide and limit the steel cable. During the lifting process, the steel cable stretches and contracts with the rotation of the take-up roller 8, and the guide frame can ensure that the steel cable moves along the predetermined path, avoiding problems such as entanglement and jumping of the steel cable during movement.

[0036] Please refer to the accompanying drawings Figure 3 - the accompanying drawings Figure 5 The inner wall of the arc-shaped plate 21 is fixedly connected with a corrugated plate 22, which can increase the friction and contact stability between the arc-shaped plate 21 and the outer wall of the pipe. The corrugated structure can better adapt to the slight unevenness of the outer wall of the pipe, so that the arc-shaped plate 21 can be more tightly attached to the surface of the pipe during clamping, 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 is fixedly connected to the outer wall of the sliding rod 18. When the sliding plate 19 drives the arc-shaped plate 21 to clamp or loosen the pipe, the first spring 23 is compressed or stretched between the sliding rod 18 and the mounting plate 15, and the fixed connection at both ends ensures that the spring force can effectively act on the entire fixing assembly.

[0037] Please refer to the accompanying drawings Figure 5 - the accompanying drawings Figure 7 The rack plate 27 and the first gear 25 are engaged, and the second gear 26 and the third gear 29 are engaged. When the sliding plate 19 moves, the rack plate 27 drives the first gear 25 to rotate, the first gear 25 drives the second gear 26 to rotate through the rotating shaft 24, and then drives the third gear 29 to rotate. The gear ratio of the third gear 29 and the second gear 26 is 1:3, so that the rotating 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 limiting column 30 moderate, which can ensure the cleaning effect and avoid damage to the outer wall of the pipe due to excessive movement speed.

[0038] 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. During the rotation of the third gear 29 to drive the movement of the cleaning plate 31, when the cleaning plate 31 encounters unevenness or greater resistance on 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 surface of the pipeline and the cleaning assembly from being damaged. 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 good contact with the outer wall of the pipeline, improving the uniformity and thoroughness of cleaning, and ensuring that the outer wall of the pipeline can be fully and effectively cleaned during hoisting.

[0039] 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 cooperation between the connecting rods 16 and the bottom plate 17 allows the mounting plate 15 to be supported during the transfer of the pipeline, so that the fixed assembly inside the mounting plate 15 can better fix the pipeline.

[0040] Working principle: during the construction of the pumped storage power station, the construction pipeline needs to be transferred to the designated position. When the pipeline needs to be transferred, the second motor 34 is controlled to start. When the second motor 34 starts, it will rotate, and the rotation of the second motor 34 will drive the worm 10 to rotate, which will drive the worm gear 3 to rotate through meshing with the worm 10, and then drive the support column 2 to rotate, so that the position of the hoisting device is adjusted to above the construction pipeline.

[0041] Subsequently, the second motor 34 is rotated, and the first motor 9 is controlled to rotate. The rotation of the first motor 9 causes the winding roller 8 to rotate, the steel cable wound on the winding roller 8 is lowered, the hook 11 slides downward, and the mounting plate 15 is placed above the construction pipeline.

[0042] Further, the first motor 9 is controlled to start again to realize the hoisting function. During hoisting, the steel cable pulls the hook 11 to slide, further driving the balance beam 12 to slide. When the balance beam 12 slides, it slides along the surface of the slide column 13, and at the same time, it drives the connecting rod 20 to rotate under the action of the gravity of the mounting plate 15. When the connecting rod 20 rotates, it drives the two sliding plates 19 to slide in opposite directions, further driving the arc-shaped plate 21 at the bottom of the sliding plate 19 to slide, achieving the effect of fixing the construction pipeline.

[0043] While the arc-shaped plate 21 slides, the rack plate 27 also slides, when the rack plate 27 slides, the first gear 25 is driven to rotate by the meshing between the first gear 25 and the rack plate 27, further drives the rotating shaft 24 to rotate, so that the two second gears 26 rotate, when the second gear 26 rotates, the third gear 29 is driven to rotate by the meshing between the second gear 26 and the third gear 29, further drives the limiting column 30 on the surface of the third gear 29 to rotate, and the construction pipeline connecting port is rotated and cleaned.

[0044] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
