Description

Technical Field

[0001] This application relates to the technical field of equipment assembly for hydropower generating units, particularly to a transportation device for a water distribution ring pipe and a transportation method for the water distribution ring pipe. Background Art

[0002] With the development of the equipment assembly technology for water bucket type units in hydropower stations, water bucket type hydro-generator units are gradually evolving towards large-scale and giant-scale, thus giving rise to the modular construction technology for ultra-heavy water distribution ring pipes. This technology is characterized by extremely large structural dimensions, overweight per single section, and extremely high requirements for installation accuracy.

[0003] In related technologies, the installation of water distribution ring pipes mainly adopts the direct hoisting method using a truck crane: First, a truck crane is positioned at the outer edge of the unit pit, such as in the downstream tail water area or a temporary construction passage, and then the vertical transportation and installation positioning of single-section pipe fittings are carried out through the hoisting machinery.

[0004] However, the above traditional hoisting method has technical bottlenecks in practical applications. Firstly, with the increase in unit capacity, the maximum outer diameter of the water distribution ring pipe has exceeded 12 meters, and the weight per single section generally exceeds 50 tons. The rated lifting capacity of conventional truck cranes at a hoisting radius of 20 - 40 meters is seriously insufficient. Secondly, there are physical limitations in the effective working surface width at the construction sites of high mountain and canyon type power stations. Thirdly, there is a dynamic swing during the hoisting process of the water distribution ring pipe, resulting in a high rework rate in the subsequent welding process and seriously affecting the construction progress.

[0005] In summary, the traditional water distribution ring pipe for hydro-generators has problems such as difficult installation, long installation cycle, and potential construction safety hazards. Summary of the Invention

[0038] To make the above objects, features, and advantages of the present application more apparent and understandable, the following provides a detailed description of the specific implementation manners of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0039] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0040] In addition, if terms such as "first" and "second" appear, these terms are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0041] In the present application, unless otherwise clearly defined and limited, if terms such as "mounted", "connected", "coupled", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0042] In this application, unless otherwise clearly specified and defined, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0044] The increase in the capacity of the generator set results in a large outer diameter and a large single-section weight of the water distribution ring pipe. The rated lifting capacity of a conventional truck crane cannot meet the requirements; the effective working surface width of the construction site of a high mountain and canyon type power station is insufficient, restricting the operation space of large lifting equipment; the dynamic swing amplitude of the pipe fittings during the lifting process leads to a high rework rate of the welding process, which not only prolongs the installation period but also increases the potential safety hazards during construction.

[0045] Refer to Figure 1 、 Figure 3 、 Figure 5 , Figure 1 which shows the structural schematic diagram of the movable vehicle 20 in an embodiment of the present application. Figure 3 which shows the installation schematic diagram of the guide rail structure 10 in an embodiment of the present application. Figure 5 which shows the structural schematic diagram of the guide rail structure 10 in an embodiment of the present application.

[0046] To solve the above technical problems, a transportation device for a water distribution ring pipe 30 provided in an embodiment of the present application includes a guide rail structure 10, a movable vehicle 20 and a lifting mechanism. Each component cooperates with each other to jointly realize the transportation and lifting operations of the water distribution ring pipe 30 and achieve the assembly of the water distribution ring pipe 30.

[0047] In this embodiment, the guide rail structure 10 includes an annular track 11, and the annular track 11 is connected to the base layer 13 through an anchoring assembly 12. The movable vehicle 20 includes a load-bearing frame 21 and a steering wheel set 22. The load-bearing frame 21 is used to carry the water distribution ring pipe 30, and the steering wheel set 22 is used to travel on the annular track 11. A lifting mechanism is arranged on the movable vehicle 20, including a plurality of lifting units distributed outside the annular track 11, and the lifting units are used to lift the water distribution ring pipe 30.

[0048] The guide rail structure 10 includes an annular track 11, and the annular track 11 is tightly connected to the base layer 13 through an anchoring assembly 12. The annular track 11 is made of high-strength steel, and the outer diameter of the annular track 11 is larger than the outer diameter of the water distribution ring pipe 30, ensuring that the water distribution ring pipe 30 can move along the path of the annular track 11 driven by the movable vehicle 20 to achieve transportation. The outer diameter or inner diameter of the annular track 11 can be adaptively adjusted according to the size of the water distribution ring pipe 30 and the requirements of the transportation path to ensure the stable travel of the movable vehicle 20.

[0049] The base layer 13 is a concrete layer, and the anchoring assembly 12 is embedded in the concrete layer. The annular track 11 is connected to the anchoring assembly 12. During the construction of the base layer 13, the anchoring assembly 12 is embedded in the base layer 13 corresponding to the path of the annular track 11, and the annular track 11 is fixedly installed on the anchoring assembly 12 through a connecting piece to ensure the stability of the annular track 11.

[0050] The movable vehicle 20 includes a load-bearing frame 21 and a steering wheel set 22. The load-bearing frame 21 is welded by square steel and is a square structure as a whole. Multiple strengthening cross beams or longitudinal beams can be arranged inside the load-bearing frame 21 to improve the load-bearing capacity.

[0051] The steering wheel set 22 consists of four heavy-duty wheels arranged at the four corners of the load-bearing frame 21, and each wheel is installed at the bottom of the load-bearing frame 21. The wheels can be made of high-strength rubber material, and their outer diameter or size is adapted to the annular track 11.

[0052] The wheels are connected to the steering shaft through bearings, the steering shaft is connected to the load-bearing frame 21, the steering shaft is equipped with a steering drive device, and the wheels are equipped with independent drive devices. The steering drive device adopts an electro-hydraulic steering system, and the wheel drive device adopts a drive motor to realize driving the wheels to turn or move forward and backward, so that the movable vehicle 20 can travel smoothly on the annular track 11 to achieve the transportation of the water distribution ring pipe 30.

[0053] The lifting mechanism is arranged on the movable vehicle 20 and includes four lifting units distributed outside the annular track 11. Each lifting unit includes an electric hydraulic cylinder, a piston rod, and a support seat. The hydraulic cylinder is fixed outside the bearing frame 21. One end of the piston rod is connected to the hydraulic cylinder, and the other end is connected to the support seat. The support seat is used to abut against the water distribution ring pipe 30. The support seat is made of steel plate, and its surface is provided with anti-slip patterns to increase the contact friction with the movable vehicle 20 or the water distribution ring pipe 30 and improve the support stability.

[0054] The four lifting units are connected to the hydraulic pump station through hydraulic pipelines. The hydraulic pump station is equipped with a pressure regulating valve. By controlling the hydraulic pump station, the synchronous or independent lifting actions of the four lifting units can be realized to meet the lifting requirements of the water distribution ring pipes 30 with different heights or weights.

[0055] In the specific implementation process, the water distribution ring pipe 30 is placed on the bearing frame 21 of the movable vehicle 20; the steering wheel set 22 of the movable vehicle 20 is controlled to move along the annular track 11 to the designated installation position, and the movable vehicle 20 is fixed; the lifting units are controlled to rise synchronously. After the movable vehicle 20 and the water distribution ring pipe 30 are integrally lifted to the designated installation height, the water distribution ring pipe 30 is fixed using a support structure. Finally, the movable vehicle 20 is separated from the water distribution ring pipe 30, and the movable vehicle 20 is controlled to descend to the annular track 11. Repeat the above process until multiple sections of the water distribution ring pipes 30 are all transported to the designated installation positions for assembly, realizing the transportation and installation process of the water distribution ring pipes 30.

[0056] As described above, through the cooperation of the annular track 11 and the movable vehicle 20, the flexible transportation of the water distribution ring pipes 30 in a limited space is realized, greatly improving the transportation efficiency. At the same time, the setting of the lifting mechanism enables the installation height of the water distribution ring pipes 30 to be accurately adjusted, effectively ensuring the installation quality of the generator set. In addition, the transportation device is easy to operate, safe and reliable, reducing the safety hazards caused by manual operation, and providing a strong guarantee for the construction and maintenance of the generator set.

[0057] Combined with Figure 5 shown in Figure 5 This is a schematic structural diagram of the guide rail structure 10 provided in an embodiment of the present application.

[0058] In some embodiments, the guide rail structure 10 further includes at least two groups of extension tracks, and the extension tracks are connected to the annular track 11. The extension tracks include a first extension track 111 and a second extension track 112, and the extension direction of the first extension track 111 is perpendicular to the extension direction of the second extension track 112.

[0059] Specifically, the guide rail structure 10 further includes two sets of extended rails, namely the first extended rail 111 and the second extended rail 112. The first extended rail 111 is disposed on one side of the annular rail 11, and the second extended rail 112 is disposed on the other side of the annular rail 11. The first extended rail 111 and the second extended rail 112 are respectively connected to the annular rail 11. The first extended rail 111 or the second extended rail 112 extends horizontally, and its rail material and dimensional specifications are the same as those of the annular rail 11 to ensure the stable travel of the movable vehicle 20.

[0060] The extending direction of the second extended rail 112 is perpendicular to the extending direction of the first extended rail 111, forming a layout similar to an L shape, so that the movable vehicle 20 can enter and exit from the two extended rails respectively. For example, taking the first extended rail 111 and the second extended rail 112 as entrances respectively, and the multi-section water distribution ring pipes 30 enter the annular rail 11 from the two extended rails respectively, which is beneficial to complete the transportation of the water distribution ring pipes 30 in a narrow space, improve the flexibility of assembly, and improve the installation efficiency.

[0061] Combined Figure 2 、 Figure 3 shown, Figure 2 is a partial structural schematic diagram of the movable vehicle 20 provided in an embodiment of the present application. Figure 3 is an installation schematic diagram of the guide rail structure 10 provided in an embodiment of the present application.

[0062] In some embodiments, the anchoring assembly 12 includes a plurality of channel steels 121 embedded in the base layer 13, and there is a spacing between the plurality of channel steels 121. A track support plate is welded to the part of the plurality of channel steels 121 exposed from the base layer 13.

[0063] Specifically, the anchoring assembly 12 is the part where the guide rail structure 10 is connected to the base layer 13, and is composed of a plurality of channel steels 121 embedded in the base layer 13. In this embodiment, the anchoring assembly 12 uses 20a channel steels 121, and the plurality of channel steels 121 are evenly embedded in the base layer 13 along the trend of the annular rail 11. The spacing between the channel steels 121 is 0.5 m to ensure the uniform force and stability of the base layer 13.

[0064] The embedding depth of the channel steel 121 is determined according to the strength and thickness of the base layer 13. In this embodiment, the embedding depth is 1.2 m. The height of the part of the channel steel 121 exposed from the base layer 13 is 0.3 m, and the exposed part is firmly connected to the track support plate by welding technology. The track support plate uses high-quality steel plates with a thickness of 20 mm, and its width matches the width of the channel steel 121, and the length is determined according to the size of the annular rail 11 to ensure the effective support for the annular rail 11.

[0065] In one embodiment, the annular track 11 is an annular steel rail made by cold bending process, and the bottom end of the annular steel rail is fixedly connected to the track support plate through a track pressing plate.

[0066] Specifically, the annular track 11 is an annular steel rail made by cold bending process, and the rail grade is 48kg grade. The cold bending process can ensure that the steel rail maintains good mechanical properties and dimensional accuracy during the bending process, reduce the stress concentration inside the steel rail, and improve the service life of the steel rail.

[0067] The bottom end of the annular steel rail is fixedly connected to the track support plate through a track pressing plate. The track pressing plate is made of high-strength cast steel, and a track pressing plate is arranged every 0.8m. The annular steel rail and the track support plate are tightly fixed together by bolts to ensure the stability and safety of the steel rail during transportation.

[0068] In one embodiment, the carrying frame 21 is a square frame structure formed by welding I-beams; the steering wheel set 22 includes heavy-duty wheels distributed at the four corners of the carrying frame 21, and the heavy-duty wheels are slidably arranged on the top end of the annular steel rail.

[0069] Specifically, the carrying frame 21 is a square frame structure formed by welding 32a I-beams. The 32a I-beam has high strength and stiffness and can bear the weight of the water distribution ring pipe 30. Multiple strengthening cross beams and vertical beams are arranged inside the square frame structure to improve the overall stability of the carrying frame 21.

[0070] The steering wheel set 22 includes four heavy-duty wheels distributed at the four corners of the carrying frame 21. The heavy-duty wheels are made of alloy steel. The wheel diameter is 250mm, and the single-wheel load capacity is 15 tons, which can meet the total weight requirements of the carrying frame 21 and the water distribution ring pipe 30.

[0071] The heavy-duty wheels are slidably arranged on the top end of the annular steel rail. The wheels are equipped with independent steering mechanisms and can be steered by hydraulic or electric drive methods, which can adapt to the turning requirements of the annular track 11.

[0072] In one embodiment, the lifting unit includes electric hydraulic cylinders symmetrically arranged on both sides of the square frame structure.

[0073] Specifically, the lifting mechanism is arranged on the movable vehicle 20 and includes electric hydraulic cylinders symmetrically arranged on both sides of the square frame structure. The electric hydraulic cylinders are designed with high precision and large thrust. The cylinder diameter is 120mm, and the stroke is 500mm - 1000mm, which can be adjusted according to the actual installation height requirements.

[0074] Each electro-hydraulic cylinder is equipped with an independent hydraulic system, which can realize the synchronous or independent lifting action of the cylinder. The lifting force of each cylinder can reach 15 tons. When four cylinders work simultaneously, the maximum lifting weight can reach 60 tons, which can meet the lifting requirements of the water distribution ring pipe 30 with different weights and heights.

[0075] Combined with Figure 4 、 Figure 6 、 Figure 7 as shown, Figure 4 is a schematic transportation diagram of the water distribution ring pipe 30 provided in an embodiment of the present application. Figure 6 is a schematic flow chart of the transportation method of the water distribution ring pipe 30 provided in an embodiment of the present application Figure 1 . Figure 7 is a schematic flow chart of the transportation method of the water distribution ring pipe 30 provided in an embodiment of the present application Figure 2 .

[0076] In some embodiments, a transportation method of the water distribution ring pipe 30 is further provided. Using the above-mentioned transportation device and auxiliary equipment of the water distribution ring pipe 30, the method includes the following steps:

[0077] S1. Fix the annular track 11 in the base layer 13 through the anchoring component 12;

[0078] S2. Transport a single section of the water distribution ring pipe 30 along the path of the annular track 11 to the target position through the movable vehicle 20;

[0079] S3. Lift the movable vehicle 20 and the water distribution ring pipe 30 to a preset elevation and fix them through the lifting unit.

[0080] In this embodiment, the auxiliary equipment is a truck crane 40 with a load-bearing capacity of at least 400 tons, which is used for the hoisting operation of a single section of the water distribution ring pipe 30.

[0081] In step S1, a plurality of 20a channel steels 121 are sequentially embedded in the base layer 13. The spacing between the channel steels 121 is strictly controlled at 0.5 m, and the embedding depth is 1.2 m. High-strength concrete is used to pour and fix the periphery of the channel steel 121 to ensure the close combination of the channel steel 121 and the base layer 13.

[0082] Place the track support plate with a thickness of 20 mm on the exposed part of the channel steel 121, and perform preliminary fixing by spot welding, and then perform full welding.

[0083] Use the truck crane 40 to hoist the 48 kg-class cold-formed ring rail above the track support plate so that the bottom end of the rail is in preliminary contact with the track support plate. Fix the ring rail and the track support plate through the track pressing plate, and use high-strength bolts with a specification of M24 and a strength grade of 8.8 to tighten them. The tightening torque reaches 400 N·m to ensure the firm connection between the rail and the track support plate without looseness.

[0084] In step S2, the movable vehicle 20 is placed on the annular track 11. The single-section water distribution ring pipe 30 is lifted by the truck crane 40 above the bearing frame 21 of the movable vehicle 20. The water distribution ring pipe 30 is fixed to the bearing frame 21 through a fixture. The movable vehicle 20 is started to slowly travel along the annular track 11 to transport the water distribution ring pipe 30 to the target position.

[0085] In step S3, after the movable vehicle 20 travels to the installation target position of the water distribution ring pipe 30, the operation of the vehicle is stopped. The electric hydraulic cylinder is started to synchronously lift the four cylinders. When the water distribution ring pipe 30 is lifted to the preset elevation, bolts are used to connect and fix the water distribution ring pipe 30 to the corresponding parts of the generator set.

[0086] In one of the embodiments, in step S2 of transporting the single-section water distribution ring pipe 30 along the path of the annular track 11 by the movable vehicle 20 to the target position, the following steps are included:

[0087] S21. Move the first section of the water distribution ring pipe 30 from the first extension track 111 along the annular track 11 to the second extension track 112;

[0088] S22. Move the middle section of the water distribution ring pipe 30 from the first extension track 111 to the middle area of the annular track 11, with a spacing between the middle section and the first section;

[0089] S23. Move the other sections from the first section to the middle section or the other sections from the middle section to the last section of the water distribution ring pipe 30 to both sides of the middle section for assembly respectively.

[0090] Specifically, taking the water distribution ring pipe 30 having thirteen sections as an example. The movable vehicle 20 travels to the starting end of the first extension track 111. The first section of the water distribution ring pipe 30, that is, the first section, is lifted by the truck crane 40 onto the bearing frame 21 of the movable vehicle 20. The movable vehicle 20 is started and slowly travels along the first extension track 111 to the annular track 11, and then moves along the annular track 11 to the second extension track 112.

[0091] The movable vehicle 20 returns from the second extension track 112 to the starting end of the first extension track 111. The middle section of the water distribution ring pipe 30, that is, the seventh section, is lifted by the truck crane 40 onto the bearing frame 21. The vehicle is operated to travel along the first extension track 111 to the middle area of the annular track 11.

[0092] According to the above method, the other sections from the first section to the middle section of the water distribution ring pipe 30, that is, the sixth section, the fifth section, the fourth section, the third section, and the second section close to the middle section, are sequentially transported to the designated positions along the annular track 11 in the clockwise direction one by one.

[0093] Similarly, for the other sections from the middle section to the end section, namely the eighth section, ninth section, tenth section, eleventh section, twelfth section, and thirteenth section, they are successively transported to the designated positions along the annular track 11 in the counterclockwise direction one by one. After all the water distribution ring pipes 30 are transported to the designated positions, welding or bolt connection assembly is carried out one by one.

[0094] In one of the embodiments, in step S3 of lifting the movable vehicle 20 and the water distribution ring pipe 30 to a preset elevation and fixing them, it further includes the steps: S31. After lifting the movable vehicle 20 and the water distribution ring pipe 30 to the preset elevation, use a support structure to fix the water distribution ring pipe 30, and separate the movable vehicle 20 from the water distribution ring pipe 30.

[0095] Specifically, when the water distribution ring pipe 30 is lifted to the preset elevation, use a truck crane 40 to lift the support structure, and hoist a steel structure bracket with a load-bearing capacity of 50 tons to the lower part of the water distribution ring pipe 30 to make it in close contact with the water distribution ring pipe 30. Fix the support structure to the base layer 13 with bolts. After confirming that the support structure is firmly fixed, operate the electric hydraulic cylinder to slowly lower it to separate the movable vehicle 20 from the water distribution ring pipe 30.
