Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering equipment, in particular to a water guide mechanism turnover device and a turnover component thereof. Background Art

[0002] The cross-flow water guide mechanism is installed horizontally. During the installation and removal process, a crucial turning step must be experienced. In traditional operations, the main and auxiliary hooks of the bridge crane are usually used to cooperate with each other, and the jack is used as a turning tool to perform this operation. However, facing the water guide mechanism with a large volume and concentrated weight, the existing solution has certain limitations.

[0003] Specifically, when using a jack for flipping, since the contact area between the water-guiding mechanism and the jack is relatively limited, as the flipping angle gradually increases, the force point shifts and the torque changes, making the load on the jack more concentrated. There is a risk of instantaneous detachment due to insufficient carrying capacity, that is, the jack may pop out after flipping to a certain angle due to inability to effectively support it, which undoubtedly poses a potential threat to operational safety.

[0004] Therefore, there is an urgent need for a more scientific, safe and stable water guide mechanism flipping device to solve the difficulties encountered in the prior art in handling the flipping process of large-scale cross-flow water guide mechanisms and ensure the safety and efficiency of the entire flipping operation. Utility Model Content

[0005] The utility model aims to provide a water guide mechanism flipping device and a flipping assembly thereof, so as to solve the problem of potential threats in the flipping device of the cross-flow type water guide mechanism proposed in the background technology during use.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water guide mechanism flipping device comprises a flipping platform, wherein the flipping platform has a first supporting part and a second supporting part, the first supporting part has a first supporting surface, the second supporting part has a second supporting surface, the first supporting surface and the second supporting surface form a first angle surface; the center of gravity and the lifting point of the water guide mechanism are located within the angle range corresponding to the first angle surface.

[0008] Furthermore, a side surface of the first angled surface extends in a horizontal direction.

[0009] Furthermore, the first supporting portion and the second supporting portion have a transition section within the first angled surface, the transition section has an upper end, a middle end and a lower end, and the middle end is not in the same plane as the upper end and the lower end.

[0010] Furthermore, the upper end has a first arc portion, and the center of the first arc portion faces downward.

[0011] Furthermore, the first supporting portion has a third supporting surface, the second supporting portion has a fourth supporting surface, the third supporting surface and the fourth supporting surface form a second angled surface; and the first angled surface is always wrapped by the second angled surface.

[0012] Furthermore, two side surfaces of the first angled surface are parallel to two side surfaces of the second angled surface.

[0013] Furthermore, the second angled surface has a second arc portion, and the center of the second arc portion faces upward.

[0014] A flipping assembly comprises the above-mentioned water-guiding mechanism flipping device, wherein the water-guiding mechanism has a first side portion and a second side portion, and the center of gravity of the water-guiding mechanism is located between the first side portion and the second side portion; the first support portion and the second support portion of the flipping device are both installed on the first side portion, and the lifting point is formed on the second side portion.

[0015] Furthermore, the first side portion is located at the bottom of the water guiding mechanism, and the second side portion is located at the top of the water guiding mechanism.

[0016] Furthermore, the first side portion is formed at the junction of the runner chamber of the water guide mechanism and the surface where the outer water distribution ring handle is located, and the second side portion is formed on the surface where the outer water distribution ring handle of the water guide mechanism is located.

[0017] The advantages of the water guide mechanism flipping device described in the utility model over the prior art are:

[0018] By precisely covering the center of gravity and the lifting point of the water-conducting mechanism within the range formed by all rays on the first angled surface, the center of gravity of the turning platform can always be kept collinear or on a straight line with the center of gravity of the water-conducting mechanism and the lifting point during the turning process, regardless of the turning angle. Such a design ensures the stability and safety of the turning action, and avoids the risk of equipment imbalance, overturning, etc. caused by the shift of the center of gravity.

[0019] The advantages of the flip assembly described in the utility model over the prior art are:

[0020] By installing the first support part and the second support part of the flipping device on the first side part, this design enables the flipping device and the water guide mechanism to form a mechanically balanced and stable overall structure. During the flipping operation, the two support parts can provide uniform and strong support, effectively dispersing the weight load of the water guide mechanism, and ensuring that the flipping process is smooth.

[0021] Balance the force during the process to prevent the equipment from shaking, tilting or becoming unstable due to uneven force.

[0022] At the same time, the lifting point is set on the second side. This layout ensures that the center of gravity of the water-guiding mechanism remains within a controllable range during the lifting process, which helps to achieve precise angle control and position adjustment. The lifting point cooperates with the flipping device that has formed a mechanically balanced whole, further enhancing the stability and safety of the entire flipping system and improving the efficiency of the flipping operation.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not intended to be used for

[0030] Limit the utility model.

[0031] Example 1: Figure 1 As shown, a water guide mechanism flipping device and a flipping assembly thereof provided in this embodiment include a flipping platform 10. The main body of the flipping platform 10 is made of high-strength steel structure or cast steel material to ensure that it has excellent bearing capacity and sufficient rigidity.

[0032] The turning table 10 is composed of two key support components, namely the first support part 101 and the second support part 102. The two support parts can be independent structural units firmly combined with the main body of the turning table 10 by precision welding, integral casting or mechanical connection. The two turning tables 10 can be arranged at a certain angle, such as 90 degrees. The purpose of this angle setting is to better adapt to the shape and size of the water guide mechanism 20 and provide a better support effect.

[0033] Specifically, the first support portion 101 has a planar second support portion 1021011, and the second support portion 102 is provided with a second support surface 1021 matched therewith, and the two together form a first angled surface 103 for stably supporting the water guide mechanism 20. In the actual operation process, the center of gravity of the water guide mechanism 20 is first accurately calculated, and its center of gravity is ensured to be within the angle range corresponding to the first angled surface 103, that is, the center of gravity of the turning platform 10 can always be kept in line with the center of gravity of the water guide mechanism 20 and the lifting point 30 or on a straight line, so as to achieve the best mechanical balance and safety during the turning process. This design greatly reduces the risk of unstable turning or accidental sliding caused by the center of gravity offset, thereby ensuring that the water guide mechanism 20 will not overturn, be damaged, or other safety issues during the turning operation.

[0034] In addition, in order to improve the applicability and flexibility of the flip device, the angle between the first support portion 101 and the second support portion 102 can be adjusted according to the water guide mechanism of different specifications and shapes.

[0035] 20 is preset and adjusted to ensure that no matter what type of water guide mechanism 20 can be properly and stably supported. At the same time, the turning table 10 can also be equipped with a precision pressure monitoring system to monitor the state of each force point during the turning process in real time to ensure that the entire turning operation is always in a controllable state.

[0036] Embodiment 2: Based on the above embodiment, in order to further ensure stability during the flipping process, especially for the support requirement of the water guide mechanism 20 in the horizontal direction, one side surface of the above first angled surface 103 extends in the horizontal direction. Such a structural design can effectively increase the contact area with the water guide mechanism 20, effectively disperse the force, and reduce the risk of instability caused by excessive local pressure. , thereby improving the support force and stability, especially when the water guide mechanism 20 flips over to a nearly horizontal position, it can significantly reduce the risk of shaking or slipping caused by uneven force.

[0037] Specifically, the first angled surface 103 may be a V-shaped or trapezoidal structure with a specific angle, and the bottom edge of the V-shaped structure or one or more sides of the trapezoidal structure may be appropriately stretched in the horizontal direction. At the same time, in order to further enhance the friction and anti-slip performance between the support surface and the water guide mechanism 20, a wear-resistant, anti-slip material layer or other auxiliary fixing device may be added to the first angled surface 103 formed after stretching to ensure the safety and accuracy of the flipping process.

[0038] Example 3: Figure 2 As shown, based on the above embodiment, in order to ensure the stability in the vertical direction during the flipping process and adapt to the support of the water guide mechanism 20 at different flipping angles

[0039] Specifically, the first support portion 101 and the second support portion 102 are provided with a non-planar transition structure having an upper end, a middle end and a lower end in the region forming the first angled surface 103 .

[0040] The transition section can be designed in a curved or broken line shape, specifically a continuous arc surface or an inclined surface structure formed by splicing multiple planes. The design of this non-planar transition section cleverly constructs a dynamic adaptive support area within the first angled surface 103, and its upper end, middle end and lower end are optimized according to the distribution of the center of gravity of the water guide mechanism 20 and the force direction that may change during the flipping process.

[0041] When the water guide mechanism 20 is in the process of flipping, whether it is in a vertical state or a nearly horizontal state, the transition section can ensure that a uniform and continuous contact area and a stable supporting force are provided to the water guide mechanism 20. Especially when flipping to a nearly horizontal position, the appropriate bending or turning design in the middle of the transition section can effectively disperse the pressure in the vertical direction and prevent instability caused by excessive local stress.

[0042] In addition, the design of the three-dimensional transition section can also enhance the fit of the turning platform 10 to the contour of the water guide mechanism 20, reduce the shaking or friction loss during the turning process, and thus improve the safety and efficiency of the turning operation. At the same time, for the water guide mechanism 20 with a complex shape or a large size, this non-planar transition section structure can better adapt to its appearance characteristics and meet the needs of diversified turning conditions.

[0043] Embodiment 4: Based on the above embodiment, the upper end has a first arc portion, the center of which faces downward, and its design purpose is mainly to adjust the edge of the outer water distribution ring of the water guide mechanism 20.

[0044] Specifically, when the flip device is installed on the water guide mechanism 20, by adjusting the position and angle of the flip table 10, the first arc portion can be closely attached to and snapped into the protruding portion of the outer water distribution ring of the water guide mechanism 20, thereby achieving a stable connection.

[0045] When the water guide mechanism 20 needs to be flipped, the interlocking structure of the first arc portion can not only provide strong and uniform support during the flipping process, but also ensure that the water guide mechanism 20 always remains stable at different flipping angles, preventing sliding or shaking caused by uneven force. In addition, the design of the first arc portion also takes into account the convenience of disassembly and assembly, ensuring that when installing or removing the flipping device, it can be smoothly docked and separated with the outer water distribution ring of the water guide mechanism 20, effectively improving work efficiency and safety.

[0046] Example 5: Figure 3 As shown, based on the above embodiment, the first support portion 101 has a third support portion 1012, and the second support portion 102 has a fourth support surface 1022. By cleverly designing and combining the third support portion 1012 and the fourth support surface 1022, a second angle surface 104 that complements the first angle surface 103 is formed. The design of the second angle surface 104 is intended to achieve all-round wrapping and support for the first angle surface 103.

[0047] Specifically, the second angled surface 104 is used to form a more stable contact and support with the ground or other working areas, ensuring that the turning device can provide sufficient stability and safety no matter at what angle when the water guiding mechanism 20 is turned over. In particular, when the water guiding mechanism 20 needs to be turned over to a nearly horizontal position, the first angled surface 103 may not be able to completely fit the working area such as the ground or the supporting platform. At this time, the second angled surface 104 is

[0048] It can effectively fill this gap. Through its all-round wrapping and support design, there is always enough force-bearing area during the entire flipping process, avoiding instability caused by excessive local force.

[0049] Embodiment 6: Based on the above embodiment, the two side surfaces of the first angled surface 103 are parallel to the two side surfaces of the second angled surface 104. The parallel structure helps to ensure that the water guiding mechanism 20 always maintains good centering when flipped to different angles, preventing deviation during the flipping operation, thereby avoiding instability caused by the shift of the center of gravity and the safety risks that may be caused by it.

[0050] Specifically, when the flipping device is working, whether the water guide mechanism 20 is flipped from a vertical state to a horizontal state or at any other flipping angle, the water guide mechanism 20 can always fit the support structure and flip smoothly along the preset path because the two side surfaces of the second clamping surface and the second angled surface 104 remain parallel. This precise centering design not only enhances safety during the flipping process, but also improves work efficiency and reduces unnecessary wear and potential failures.

[0051] Embodiment 7: On the basis of the above embodiments, on the basis of the above embodiments, the second angled surface 104 has a second arc portion, and the center of the second arc portion faces upward. For example, the second arc portion can be a curved surface structure such as a semicircular, elliptical or parabolic shape. When the water guiding mechanism 20 is flipped to a nearly vertical state, the second arc portion can provide a more uniform and gradual supporting force, effectively avoiding local stress concentration, thereby ensuring safety during the flipping process.

[0052] At the same time, when the water-guiding mechanism 20 needs to flip from a vertical state to a horizontal state, the design of the second angled surface 104 further enhances the stability and reliability of the water-guiding mechanism 20 turning over. Specifically, the second angled surface 104 and the first angled surface 103 complement each other to form an all-round support structure. The design of the second angled surface 104 enables the water-guiding mechanism 20 to be in closer contact with the ground or other working areas during the turning process, providing more stable support. At the same time, the design of the second angled surface 104 also takes into account the characteristics of the center of gravity offset of the water-guiding mechanism 20, and through precise calculation and control, ensures that the water-guiding mechanism 20 can smoothly and reliably complete the turning action when the center of gravity offsets.

[0053] Example 8: Figure 4 As shown, a turnover assembly provided in this embodiment includes a water guide mechanism 20 and a water guide mechanism 20 turnover device. The water guide mechanism 20 may be a through-flow water guide mechanism 20, which has a cylindrical structure in appearance. The diameter of the cylinder is usually greater than its height. This design helps to achieve efficient guidance and conversion of water flow inside. A runner chamber is precisely installed at the center of the water guide mechanism 20 to accommodate the runner component of the turbine and ensure that the water flow drives the runner to rotate smoothly.

[0054] On the outer circumferential surface, the water guide mechanism 20 is evenly distributed with an outer water distribution ring structure. This design ensures that the water flow from the water inlet to the water outlet is evenly distributed and the direction is controllable, thereby optimizing the energy conversion efficiency of the entire hydropower station. At the same time, in order to facilitate the hoisting, flipping and maintenance operations of the water guide mechanism 20, the flipping device in this embodiment cleverly sets the first support part 101 and the second support part 102 on the appropriate side of the water guide mechanism 20, so that the water guide mechanism 20 always maintains a good mechanical balance during the flipping process.

[0055] The lifting point 30 is carefully arranged on the other side according to the center of gravity of the water guiding mechanism 20. Through effective cooperation with the flipping device, the water guiding mechanism 20 can be guaranteed to be safe and stable regardless of flipping from a vertical state to a horizontal state or at any flipping angle, thereby greatly improving the reliability and safety of the flipping operation.

[0056] Embodiment 9: Based on the above embodiment, the specific structural layout of the flip assembly is further described. The first side portion 201 is located at the bottom area of ​​the water guide mechanism 20, ensuring that the flip device can provide sufficient and uniform support force, so that the water guide mechanism 20 always remains stable during the flipping process, preventing the risk of equipment overturning due to the center of gravity shift.

[0057] The second side portion 202 is located at the top of the water guide mechanism 20, where a lifting point 30 is provided. When a flipping operation is required, a crane or other lifting equipment is connected to the lifting point 30, so that the flipping angle and speed of the water guide mechanism 20 can be accurately controlled. Since the lifting point 30 is located at the top of the water guide mechanism 20, such a design helps to effectively lift the water guide mechanism 20 and ensure that the entire flipping process is more stable and safe.

[0058] Combined with the design of the first side portion 201 and the second side portion 202, the flip assembly provided by the utility model can demonstrate excellent mechanical properties and stability in practical applications, which not only improves the safety and efficiency of the flipping operation, but also has good adaptability and is suitable for cross-flow water guiding mechanisms 20 of various specifications and shapes, meeting the installation, inspection and maintenance requirements in various occasions.

[0059] Embodiment 10: Based on the above embodiment, the layout design of the flip assembly further reflects

[0060] The first side portion 201 is cleverly formed at the key part of the water guide mechanism 20, that is, the joint of the runner chamber and the outer water distribution ring. This design ensures that the first support portion 101 and the second support portion 102 of the flipping device can directly act on the core force point of the water guide mechanism 20, providing strong support, and because they are located near the center of gravity, they are conducive to achieving mechanical balance during the flipping process.

[0061] At the same time, the second side portion 202 is formed on the surface where the outer water distribution ring of the water guide mechanism 20 is located. A lifting point 30 is provided here so that during the flipping operation, the flipping posture and speed of the water guide mechanism 20 can be accurately controlled by a crane or other lifting equipment. Since the lifting point 30 is located at the outer water distribution ring handle position on the water guide mechanism 20 with sufficient strength and stability, reliable traction and safe control of the water guide mechanism 20 during the flipping process is guaranteed.

[0062] To sum up, the flipping assembly provided by the utility model is precisely arranged according to the specific structural characteristics of the water guiding mechanism 20, which not only ensures the mechanical stability during the flipping process, but also realizes the efficient and safe flipping operation of the water guiding mechanism 20, greatly improving the work efficiency of on-site construction, maintenance and overhaul, and embodies good applicability and practicality.

[0063] Working principle: When the device is in use, the two supporting parts of the turning table 10 are first firmly connected to the first side part 201 and the second side part 202 of the water guide mechanism 20 by bolts, clamps or other fixing methods. Ensure that the first supporting part 101 and the second supporting part 102 can provide uniform and strong supporting force for the water guide mechanism 20, and make the lifting point 30 located at the preset second side part 202.

[0064] Then, the operator uses a crane or other lifting device to lift the

[0065] During the turning process, the first angled surface 103 ensures that the center of gravity of the water guiding mechanism 20 is always in the ray distribution area within its coverage range by its special design, so that at any turning angle, the turning device can provide effective support and balance for the water guiding mechanism 20.

[0066] Since a mechanically balanced overall structure has been formed between the flipping device and the water guiding mechanism 20, it can ensure that the water guiding mechanism 20 always remains stable when being lifted or flipped to different angles, thereby avoiding the risk of overturning due to uneven force.
