Description

Technical Field

[0001] This invention relates to the field of turbine guide vane assembly and disassembly technology, and in particular to a device and method for assembling and disassembling guide vanes on a turbine. Background Technology

[0002] In the maintenance and repair of water turbines, it is generally necessary to disassemble and reassemble the guide shoes. For example... Figure 1 As shown, the turbine 10 typically includes a first metal ring 101 disposed within and flush with the horizontal plane 20, and a second metal ring 102 disposed within the first metal ring 101 and extending upward. The first metal ring 101 and the second metal ring 102 together form a chamber 104 for accommodating the guide vane 103. Additionally, two threaded holes 1031 are provided on the guide vane 103.

[0003] In the prior art, when it is necessary to disassemble or assemble the guide shoe 103, workers typically use a connector (not shown in the figure) and threaded hole 1031 to fix it together, and then lift the connector. In this way, the guide shoe 103 located in the chamber 104 is removed from the turbine 10. When it is necessary to install the guide shoe 103, the opposite operation is performed.

[0004] While this setup allows for the assembly and disassembly of the guide vane 103, its lifting is typically done manually by workers, resulting in high labor intensity. Furthermore, the lack of direction-of-lifting guidance in this method easily leads to a non-linear upward trajectory for the guide vane 103. This makes the guide vane 103 prone to collisions with other components of the turbine 103, causing damage. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device and method for disassembling and assembling guide vanes on a water turbine. To achieve the above objectives, this invention employs the following technical solution: A device for assembling and disassembling guide vanes on a water turbine, the water turbine including a first metal ring disposed in and flush with a horizontal plane, and a second metal ring disposed within the first metal ring and extending upward, the first metal ring and the second metal ring together forming a chamber for accommodating the guide vanes. The device includes a lifting mechanism that is selectively fixed relative to the guide plate and allows the guide plate to move axially, and a support mechanism that abuts against a second metal ring and extends radially, the support mechanism supporting the lifting mechanism and allowing the lifting mechanism to move along the path it forms, so that the guide plate located on the lifting mechanism can move radially.

[0006] Furthermore, the support mechanism includes support rods arranged opposite each other, and a fixing part disposed at the end of the support rods for fixing the oppositely arranged support rods together. The lifting mechanism includes a limiting part that abuts against the support rods and is capable of moving along the path formed by the support rods, a flexible part that passes through the limiting part and extends axially for fixing the guide tile together, and a winding part disposed on the limiting part for winding the flexible part so that the guide tile located on the flexible part moves axially.

[0007] Furthermore, the limiting part includes a guide block disposed between the support rods, and a movable block disposed on the guide block and abutting against the support rods. The movable block and the guide block are provided with through holes that extend along the axial direction, and the through holes are used to form a channel through which the flexible part passes.

[0008] Furthermore, two threaded holes are provided on the guide plate, and a connecting part is provided at the free end of the flexible part. The connecting part includes a connecting rod that is fixed together with the free end of the flexible part, and a connecting post located on the connecting rod that allows it to cooperate with the threaded holes.

[0009] Furthermore, the winding section includes a drive section disposed on the moving block, and a winding wheel located at the force output end of the drive section for accommodating the flexible section.

[0010] Furthermore, the device also includes a telescopic mechanism connected to the support mechanism and extending axially, the free end of which is configured to abut against a horizontal surface to provide axially adjustable support for the support mechanism.

[0011] Furthermore, the telescopic mechanism includes a first rod for abutting against a horizontal surface, a second rod disposed within the first rod and capable of moving along a path formed by the first rod, and a locking part disposed on the first rod and capable of fixing the second rod relative to the first rod.

[0012] Furthermore, a receiving mechanism for receiving the telescopic mechanism is provided at the free end of the telescopic mechanism. The receiving mechanism is equipped with casters that abut against the horizontal plane, so that the receiving mechanism can move circumferentially along the first metal ring on the horizontal plane.

[0013] Furthermore, the turbine also includes a third metal ring that abuts against the radially inner side of the second metal ring and extends axially upward. A traveling wheel is also provided at the free end of the support mechanism. The side of the traveling wheel is configured to abut against the radially outer side of the third metal ring to position the movement path of the device during circumferential movement along the contour of the third metal ring.

[0014] According to a second aspect of the present invention, a method for assembling and disassembling guide tiles using the aforementioned device is provided, characterized by comprising the steps of: Step 1, arranging the device: Place the device on a horizontal surface, open the locking part, and apply an axial force to the second rod so that the axial length of the telescopic mechanism matches the axial height of the second metal ring. At the same time, apply a force to the device so that the device moves on the horizontal surface until the side of the traveling wheel on the support mechanism and the radial outer side of the third metal ring abut against each other. Step 2, Aligning the guide tiles: Apply a circumferential force to the device, so that the caster wheel moves circumferentially on the horizontal plane and the traveling wheel moves circumferentially along the path formed by the third metal ring, until the connecting part and the guide tile are aligned. Step 3, Connecting the guide plate: Insert the connecting post into the threaded hole and make the connecting post and the threaded hole engage with each other so that the connecting part and the guide plate are relatively fixed together; Step 4, Lifting the guide tile: Start the drive unit so that the drive unit drives the receiving wheel to rotate, thereby causing the receiving wheel to wind up the flexible part, and thus causing the guide tile to move axially upward. Step 5, moving the guide tile: Apply force to the limiting part, so that the limiting part moves along the path formed by the support rod until the guide tile is transferred to the preset placement position; Step 6, Moving device: Apply force to the device to make it move circumferentially until it reaches the position of the next guide tile. Then repeat steps 3 to 5 above until the disassembly of the guide tile is completed.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention includes a lifting mechanism that is selectively fixed to the guide vane and allows axial movement of the guide vane, and a support mechanism that abuts against a second metal ring and extends radially. The support mechanism carries the lifting mechanism and allows it to move along a path formed by the lifting mechanism, enabling radial movement of the guide vane located within the lifting mechanism. In this way, when the guide vane is lifted, the support mechanism can be aligned with the guide vane, thereby positioning the axial movement of the guide vane. This reduces workload and prevents collisions between the guide vane and other turbine components. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] To better understand the purpose, structure, and function of the present invention, the following detailed description, in conjunction with the accompanying drawings, provides an apparatus and method for disassembling and assembling guide vanes on a water turbine.

[0020] like Figure 1 , 2 As shown in Figure 3, the turbine 10 includes a first metal ring 101 disposed within and flush with the horizontal plane 20, and a second metal ring 102 disposed within the first metal ring 101 and extending upward. The first metal ring 101 and the second metal ring 102 together form a chamber 104 for accommodating the guide vane 103. It should be noted that the structure of the turbine 10 and the connections between its various components are well known to those skilled in the art. Therefore, they will not be described in detail here.

[0021] Figure 4 The schematic diagram illustrates the overall structure of a device according to the invention for disassembling and assembling guide vanes on a water turbine. In such a way... Figure 4In the illustrated embodiment, the device 100 for assembling and disassembling guide vanes on a water turbine includes a lifting mechanism 1. The lifting mechanism 1 is configured to allow selective fixing to the guide vane 103 and to apply an axial force to the guide vane 103, thereby driving the guide vane 103 to move axially. Specifically, the lifting mechanism 1 can raise and lower the guide vane 103 while applying force to it.

[0022] At the same time, such as Figure 4 As shown, the device 100 also includes a support mechanism 2. The support mechanism 2 abuts against the second metal ring 102 and extends radially to support the lifting mechanism 1 and allow the lifting mechanism 1 to move along the path it forms. In this way, the guide tile 103 located on the lifting mechanism 1 can move radially. Thus, the guide tile 103 located on the horizontal plane 20 can be transferred into the chamber 104, or the guide tile 103 located in the chamber 104 can be transferred to the horizontal plane.

[0023] In this configuration, when the guide tile 103 needs to be disassembled or assembled, firstly, the support mechanism 2 is mounted on the second metal ring 102, and the support mechanism 2 extends radially. Simultaneously, a lifting mechanism 1 is mounted on the support mechanism 2, and the end of the lifting mechanism 1 is aligned with the guide tile 103.

[0024] At this point, the lifting mechanism 1 is fixed together with the guide tile 103, and the lifting mechanism 1 applies an axial upward force to the guide tile 103. During this process, the force is transmitted to the guide tile 103 and drives the guide tile 103 to move axially upward until the guide tile 103 separates from the cavity 104.

[0025] Then, the force applied to the guide tile 103 is stopped, and a radial force is applied to the lifting mechanism 1, causing the lifting mechanism 1 to move along the path formed by the support mechanism 2 until the guide tile 103 is transferred to a suitable position on the horizontal plane 20. This completes the removal of the guide tile 103 from the chamber 104. However, when it is necessary to install the guide tile 103, which is located on the horizontal plane, into the chamber 104, the operation is performed in reverse order until the guide tile 103 is transferred to a suitable position in the chamber 104.

[0026] In one embodiment, such as Figure 5 As shown, the support mechanism 2 includes support rods 21 arranged opposite each other, and a fixing part 22 disposed at the end of the support rods 21 for fixing the oppositely arranged support rods 21 together. Meanwhile, the lifting mechanism 1 includes a limiting part 11, which is configured to abut against the support rods 21 and can move along the path formed by the support rods 21.

[0027] In addition, such as Figure 5 As shown, the lifting mechanism 1 also includes a flexible portion 12 that passes through the limiting portion 11 and extends axially, the flexible portion 12 being fixed together with the guide tile 103. Furthermore, the lifting mechanism 1 also includes a winding portion 13 disposed on the limiting portion 11, the winding portion 13 being configured to wind up the flexible portion 12 so that the guide tile 103 located on the flexible portion 12 can move axially.

[0028] According to a preferred embodiment of the present invention, such as Figure 5 As shown, the limiting part 11 includes a guide block 111 disposed between the support rods 21, and a movable block 112 disposed on the guide block 111 and abutting against the support rods 21. Specifically, the limiting part 11 is configured as a "T" shaped structure.

[0029] In this way, when the limiting part 11 moves along the support rod 21, the guide block 111 can guide the movement of the limiting part 11, while the moving block 112 can stably abut against the support rod 21, thereby preventing the limiting part 11 from disengaging from the support rod 21. Thus, the limiting part 11 can move stably along the path formed by the support rod 21. Simultaneously, through holes 113 are provided on the moving block 112 and the guide block 111, and the through holes 113 extend axially to form a channel through which the flexible part 12 passes.

[0030] In one embodiment, such as Figure 3 As shown, two threaded holes 1031 are also provided on the guide plate 103. Meanwhile, as... Figure 4 As shown, a connecting portion 14 is also provided at the free end of the flexible portion 12. The connecting portion 14 is configured to allow it to be fixed relative to the guide tile 103. In this embodiment, the connecting portion 14 includes a connecting rod 141 fixed relative to the free end of the flexible portion 12, and a connecting post 142 located on the connecting rod 141. Two connecting posts 142 are provided, and the relative distance between the two connecting posts 142 is approximately equal to the distance between the two threaded holes 1031.

[0031] It should be noted that, as Figure 4 As shown, the connecting post 142 is configured to allow it to engage with the threaded hole 1031. Specifically, the connecting post 142 has an external thread along its axial direction, such that the external thread can engage with the threaded hole 1031.

[0032] In one embodiment, such as Figure 4As shown, the winding section 13 includes a drive section 131 mounted on the moving block 112, and a receiving wheel 132 located at the force output end of the drive section 131 for receiving the flexible section 12. Specifically, the flexible section 12 is wound around the receiving wheel 132. In this way, the drive section 131 can drive the receiving wheel 132 to rotate, thereby achieving the winding or unwinding of the flexible section 12. This allows the guide tile 103 to move axially upwards or downwards.

[0033] In this configuration, when the guide plate 103 needs to be disassembled or assembled, firstly, the support rods 21 are positioned on the second metal ring 102 in a corresponding manner, and a fixing part 22 is provided at the end of the support rod 21 to fix the two corresponding support rods 21 together. At the same time, a limiting part 11 is provided on the support rod 21, so that the guide block 111 is located between the two support rods 21, and the moving block 112 abuts against the support rod 21.

[0034] At this time, the flexible portion 12 is inserted into the through hole 113, allowing it to extend axially. Furthermore, the end of the flexible portion 12 is wound around the take-up wheel 132, and a connecting portion 14 is provided at the free end of the flexible portion 12. Then, a drive unit 131 is mounted on the moving block 112, and the free end of the drive unit 131 is connected to the take-up wheel 132, enabling the drive unit 131 to drive the take-up wheel 132 to rotate, thereby winding up the flexible portion 12. This completes the installation of the device 100.

[0035] Next, a circumferential force is applied to the device 100, causing the support rod 21 to move circumferentially on the second metal ring 102 until the connecting portion 14 and the guide plate 103 on the support rod 21 are aligned with each other. At this time, the connecting post 142 is inserted into the threaded hole 1031, and the connecting post 142 and the threaded hole 1031 are fixed together.

[0036] Then, the drive unit 131 is activated. During this process, the drive unit 131 transmits force along its output end to the receiving wheel 132, thereby driving the receiving wheel 132 to rotate, so that the flexible part 12 located on the receiving wheel 132 continues to wind around the receiving wheel 132. During this process, as the axial length of the flexible part 12 gradually shortens, it will continuously apply force to the guide tile 103 located in the chamber 104, thereby driving the guide tile 103 to move axially upward until the guide tile 103 disengages from the chamber 104.

[0037] Finally, the drive unit 131 is closed, and a radial force is applied to the limiting unit 11, causing the limiting unit 11 to move along the path formed by the support rod 21 until the guide tile 103 is transferred to a suitable position on the horizontal plane 20. This completes the removal of the guide tile 103 from the chamber 104. However, when it is necessary to install the guide tile 103, which is located on the horizontal plane, into the chamber 104, the operation is performed in reverse order until the guide tile 103 is transferred to a suitable position in the chamber 104.

[0038] The flexible part 12 includes, but is not limited to, ropes such as steel wire rope and nylon rope. The drive part 131 is configured to either drive the collecting wheel 132 to rotate, or, when closed, restrict the movement of the collecting wheel 132. In this embodiment, the drive part 131 is a combination of a motor and a reducer, and the collecting wheel 132 is located at the force output end of the reducer. It should be noted that the connection method between the motor and the reducer, and their working principle, are well known to those skilled in the art. Therefore, they will not be described in detail here.

[0039] In one embodiment, such as Figure 4 As shown, the device 100 also includes a telescopic mechanism 3, which is configured to connect to the support mechanism 2 and extend axially. The free end of the telescopic mechanism 3 is configured to allow it to abut against the horizontal surface 20. In this way, the telescopic mechanism 3 can support the support mechanism 2. Furthermore, the axial length of the telescopic mechanism 3 can be adjusted directionally according to different support heights required. This improves the stability of the support mechanism 2.

[0040] In this embodiment, as Figure 4 As shown, the telescopic mechanism 3 includes a first rod 31 for abutting against the horizontal surface 20, and a second rod 32 disposed within the first rod 31. The second rod 32 is configured to move along the path formed by the first rod 31. In this way, the axial length of the support mechanism 3 can be adjusted by adjusting the length of the second rod 32 within the first rod 31.

[0041] At the same time, such as Figure 4 As shown, a locking part 33 is also provided on the first rod 31, the locking part 33 being configured to fix the second rod 32 relative to the first rod 31. In the illustrated embodiment, the locking part 33 includes a bolt 331 passing through the first rod 31 and perpendicular to the axis of the first rod 31. In this embodiment, the bolt 331 is configured to be threadedly connected to the first rod 31.

[0042] In this way, bolt 331 can move in a direction perpendicular to the axis of the first rod 31, and can abut against the second rod 32 during the movement. This allows bolt 331 to apply a radial force to the second rod 32. Consequently, bolt 331 can limit the movement of the second rod 32, thereby preventing continuous relative movement between the second rod 32 and the first rod 31.

[0043] In one embodiment, such as Figure 4 As shown, a receiving mechanism 4 is also provided at the free end of the telescopic mechanism 3 to support the telescopic mechanism 3. The receiving mechanism 4 is configured as a plate structure, with the telescopic mechanism 3 located at the center of the receiving mechanism 4. In this way, the centers of gravity of the telescopic mechanism 3 and the receiving mechanism 4 can be aligned with each other. This increases the stability of the telescopic mechanism 3, thereby preventing the device 100 from tipping over.

[0044] According to a preferred embodiment of the present invention, such as Figure 4 As shown, a caster wheel 41 is provided on the receiving mechanism 4. The caster wheel 41 is configured to allow contact with the horizontal surface to drive the receiving mechanism 4 to move along the horizontal surface. In this way, when the receiving mechanism 4 moves along the horizontal surface, the caster wheel 41 can change the sliding friction between the receiving mechanism 4 and the horizontal surface into rolling friction, thereby facilitating the movement of the receiving mechanism 4 on the horizontal surface.

[0045] In one embodiment, such as Figure 4 As shown, the turbine 10 also includes a third metal ring 105, which abuts against the radially inner side of the second metal ring 102 and extends axially upward. Simultaneously, a traveling wheel 23 is provided at the free end of the support mechanism 2, the side of which is configured to allow abutment against the radially outer side of the third metal ring 105. In this way, when the side of the traveling wheel 23 abuts against the radially outer side of the third metal ring 105, and the rim of the traveling wheel 23 abuts against the second metal ring 102, the second metal ring 102 and the third metal ring 105 can position the device 100 axially and radially.

[0046] Meanwhile, in this configuration, when a circumferential force is applied to the device 100, the caster wheel 41 can move circumferentially on the horizontal plane, while the traveling wheel 23 can move circumferentially by abutting against the second metal ring 102 and the third metal ring 105 respectively. This reduces the friction generated by the device 100 during circumferential movement, thus facilitating its movement.

[0047] The operation of the device 100 for disassembling and assembling guide vanes on a water turbine according to the present invention is as follows.

[0048] First, tighten bolt 331 to allow the second rod 32 to move along the path formed by the first rod 31 until the axial length of the telescopic mechanism 3 reaches a suitable value. Simultaneously, apply force to the device 100 until the side of the traveling wheel 23 at the end of the support mechanism 2 and the radially outer side of the third metal ring 105 abut against each other, while the wheel rim abuts against the second metal ring 102. This completes the installation of the device 100.

[0049] Next, a circumferential force is applied to the device 100 so that the support mechanism 2 moves circumferentially on the second metal ring 102 until the connecting part 14 and the guide plate 103 on the support rod 21 are aligned with each other. At this time, the connecting post 142 is inserted into the threaded hole 1031, and the connecting post 142 and the threaded hole 1031 are fixed together.

[0050] Then, the drive unit 131 is activated. During this process, the drive unit 131 transmits force along its output end to the receiving wheel 132, thereby driving the receiving wheel 132 to rotate, so that the flexible part 12 located on the receiving wheel 132 continues to wind around the receiving wheel 132. During this process, as the axial length of the flexible part 12 gradually shortens, it will continuously apply force to the guide tile 103 located in the chamber 104, thereby driving the guide tile 103 to move axially upward until the guide tile 103 disengages from the chamber 104.

[0051] Finally, the drive unit 131 is closed, and a radial force is applied to the limiting unit 11, causing the limiting unit 11 to move along the path formed by the support rod 21 until the guide tile 103 is transferred to a suitable position on the horizontal plane 20. This completes the removal of the guide tile 103 from the chamber 104. However, when it is necessary to install the guide tile 103, which is located on the horizontal plane, into the chamber 104, the operation is performed in reverse order until the guide tile 103 is transferred to a suitable position in the chamber 104. This completes the installation and removal of the guide tile 103.

[0052] Example 2 Figure 1-5 A second embodiment of the invention is also shown, in which a method for assembling and disassembling guide tiles using the device 100 is provided, characterized by comprising the steps of: Step 1, setting up device 100: Place device 100 on horizontal surface 20, open locking part 33, and apply force to second rod 32 along the axial direction so that the axial length of telescopic mechanism 3 matches the axial height of second metal ring 102. At the same time, apply force to device 100 so that device 100 moves on horizontal surface until the side of traveling wheel 23 on support mechanism 2 and the radial outer side of third metal ring 105 abut against each other, and the wheel rim abuts against second metal ring 102. Step 2, Aligning the guide tile 103: Apply a circumferential force to the device 100, so that the caster wheel 41 moves circumferentially on the horizontal plane and the traveling wheel 23 moves circumferentially along the path formed by the third metal ring 105 until the connecting part 14 and the guide tile 103 are aligned with each other. Step 3, connecting the guide plate 103: insert the connecting post 142 into the threaded hole 1031, and make the connecting post 142 and the threaded hole 1031 engage with each other, so that the connecting part 14 and the guide plate 103 are relatively fixed together. Step 4, lift the guide tile 103: start the drive unit 131 so that the drive unit 131 drives the receiving wheel 132 to rotate, thereby causing the receiving wheel 132 to wind up the flexible part 12, and thus causing the guide tile 103 to move upward axially. Step 5, moving guide tile 103: applying force to the limiting part 11, thereby causing the limiting part 11 to move along the path formed by the support rod 21 until the guide tile is transferred to the preset placement position. Step 6, Moving device 100: Apply force to the device 100 to make the device 100 move circumferentially until the device reaches the position of the next guide tile 103. Then repeat steps 3 to 5 above until the disassembly of the guide tile is completed.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
