Description

Technical Field

[0001] This utility model relates to the field of maintenance and repair equipment, and in particular to a maintenance and repair equipment for the turbine drive mechanism of a thermal power plant. Background Technology

[0002] A steam turbine, also known as a steam engine, is a rotary steam power unit. High-temperature, high-pressure steam passes through a fixed nozzle, becomes an accelerated airflow, and is then injected onto the blades, causing the rotor, which is equipped with rows of blades, to rotate and perform work. Steam turbines are the main equipment in modern thermal power plants and are also used in the metallurgical industry, chemical industry, and ship propulsion systems.

[0003] Existing maintenance equipment is difficult to adjust when inspecting drive mechanisms, making it difficult to clamp and fix drive mechanisms of different sizes. It is also difficult to adjust the drive mechanisms, making it difficult for operators to inspect different positions of the drive mechanisms, which in turn affects the inspection efficiency of the drive mechanisms.

[0004] The existing patent CN217055310U (a device for overhauling and repairing the drive mechanism of a steam turbine in a thermal power plant) uses an adjustable distance mechanism to adjust the distance between two mounting plates. After clamping and fixing the drive mechanism between the two mounting plates, the position of the mounting plates is fixed, thus clamping and fixing drive mechanisms of different sizes, which facilitates the inspection of the drive mechanism. By using a drive motor, when the motor shaft drives the drive gear to rotate, the drive gear and the mating gear ring drive the mounting plate to rotate, thereby making the drive mechanism clamped and fixed between the two mounting plates rotate synchronously. This facilitates the inspection of different positions of the drive mechanism and improves the inspection efficiency of the drive mechanism.

[0005] However, the aforementioned patents still have the following technical problems:

[0006] 1. The above-mentioned drive mechanism maintenance device cannot adjust the height. When the drive mechanism is being maintained, the fixed height causes the center height of a larger drive mechanism to rise when clamping it. As a result, the center line of the mounting plate clamping the drive mechanism is not on the same straight line as the axis of the drive mechanism, resulting in uneven force on the drive mechanism and affecting the stability of the clamping.

[0007] 2. The aforementioned drive mechanism maintenance device, which drives the drive gear to rotate through the motor shaft of the drive motor, drives the mounting plate to rotate through the meshing transmission between the drive gear and the mating gear ring. The entire structure is too complex, and the complex structure is prone to damage during use, affecting subsequent use.

[0008] Therefore, it is necessary to provide a device for overhauling and repairing the turbine drive mechanism of a thermal power plant to solve the above-mentioned technical problems. Utility Model Content

[0019] Compared with related technologies, the maintenance and repair device for the turbine drive mechanism of a thermal power plant provided by this utility model has the following advantages:

[0020] 1. This utility model, by setting a first lifting cylinder and a second lifting cylinder, allows for the adjustment of the height of the first and second support plates through the extension and retraction of the first and second lifting cylinders. This allows for adjustment of the height of the first and second support plates according to different sizes of drive mechanisms, facilitating adaptation to different sizes of drive mechanisms and improving the applicability of the device. Furthermore, by setting a first motor and a second motor, the first and second rotating plates can be driven to rotate, thereby rotating the drive mechanism clamped between the first and second rotating plates, changing the orientation of the drive mechanism, and facilitating the detection of different positions of the drive mechanism.

[0022] 3.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] refer to Figures 1 to 7This utility model provides a maintenance and repair device for the turbine drive mechanism of a thermal power plant, comprising: a base 1, the top of which is provided with a first moving groove 2 and a second moving groove 17, the first moving groove 2 and the second moving groove 17 respectively being installed with a first slide rail 3 and a second slide rail 18, the first slide rail 3 being connected to the bottom of a first support base 4 via a slider, the second slide rail 18 being connected to the bottom of a second support base 19 via a slider, the top of the first support base 4 and the second support base 19 respectively being provided with a first lifting groove 26 and a second lifting groove 29, the first lifting groove 26 being installed with a first lifting cylinder 27, the telescopic end of the first lifting cylinder 27 being connected to the bottom of a first support plate 5, the second lifting groove 29 being installed with a second lifting cylinder 30, the telescopic end of the second lifting cylinder 30 being connected to the bottom of a second support plate 20;

[0033] The side of the first support plate 5 is rotatably connected to the first rotating plate 6 via one end of the first rotating shaft 36. The other end of the first rotating shaft 36 passes through the side of the first support plate 5 and is connected to the drive end of the first motor 7. The first motor 7 is mounted on the first motor plate 8 connected to the first support plate 5. The side of the first rotating plate 6 is provided with a plurality of first clamping grooves 32. A first clamping slide rail 33 is installed inside the first clamping groove 32. The first clamping slide rail 33 is connected to the arc-shaped first clamping plate 34 via a slider. The side of the second support plate 20 is rotatably connected to the second rotating plate 13 via one end of the second rotating shaft 43. The other end of the second rotating shaft 43 passes through the side of the second support plate 20 and is connected to the drive end of the second motor 15. The second motor 15 is mounted on the second motor plate 16 connected to the second support plate 20. The side of the second rotating plate 13 is provided with a plurality of second clamping grooves 39. A second clamping slide rail 40 is installed inside the second clamping groove 39. The second clamping slide rail 40 is connected to the arc-shaped second clamping plate 41 via a slider.

[0034] It should be noted that the first slide rail 3, the second slide rail 18, the first clamping slide rail 33 and the second clamping slide rail 40 all adopt existing electric slide rails, and the first clamping groove 32 and the second clamping groove 39 are circumferentially distributed on the corresponding fixed plates.

[0035] During clamping, the drive mechanism can be placed between the first rotating plate 6 and the second rotating plate 13. Driven by the first slide rail 3 and the second slide rail 18, the first rotating plate 6 and the second rotating plate 13 are moved until the first and second moving plates are moved to contact the two ends of the drive mechanism, thus completing the clamping and fixing of the drive mechanism. Then, driven by the first clamping slide rail 33 and the second clamping slide rail 40, the first clamping plate 34 and the second clamping plate 41 are moved until the first clamping plate 34 contacts one end of the drive mechanism and the second clamping plate 41 contacts the other end of the drive mechanism, thereby achieving the clamping and fixing of the drive mechanism.

[0036] By setting up a first lifting cylinder 27 and a second lifting cylinder 30, the height of the first support plate 5 and the second support plate 20 can be adjusted by extending and retracting the first lifting cylinder 27 and the second lifting cylinder 30. The height of the first support plate 5 and the second support plate 20 can be adjusted according to different sizes of drive mechanisms, which is convenient to adapt to different sizes of drive mechanisms and improves the applicability of the device. By setting up a first motor 7 and a second motor 15, the first rotating plate 6 and the second rotating plate 13 can be rotated by the first motor 7 and the second motor 15, thereby realizing the rotation of the drive mechanism clamped between the first rotating plate 6 and the second rotating plate 13, changing the orientation of the drive mechanism, which is convenient for detecting different positions of the drive mechanism. Moreover, the drive by the first motor 7 and the second motor 15 is different from the drive motor driving the drive gear, driving the mating gear and the mounting plate. This reduces the complexity of the overall structure and can effectively improve the service life.

[0037] In the embodiments of this utility model, reference is made to Figure 2 , Figure 3 As shown, the first rotating plate 6 has a first rotating ring 25 on the side facing the first support plate 5. The first rotating ring 25 is rotatably connected to the first rotating groove 37, which is located on the side of the first support plate 5. The second rotating plate 13 has a second rotating ring 14 on the side facing the second support plate 20. The second rotating ring 14 is rotatably connected to the second rotating groove 44, which is located on the side of the second support plate 20.

[0038] It should be noted that by setting the first rotating ring 25, when the first rotating plate 6 rotates under the drive of the first motor 7, the stability of the first rotating plate 6 during rotation can be improved by the limiting guidance of the first rotating groove 37. Similarly, by setting the second rotating ring 14, the stability of the second rotating plate 13 during rotation can be improved by the limiting guidance of the second rotating groove 44.

[0039] In the embodiments of this utility model, reference is made to Figure 6 , Figure 7As shown, the bottom of the first support plate 5 is provided with a first drive groove 46, and the telescopic end of the first lifting cylinder 27 is connected to the top of the inside of the first drive groove 46. The bottom of the second support plate 20 is provided with a second drive groove 47, and the telescopic end of the second lifting cylinder 30 is connected to the top of the inside of the second drive groove 47.

[0040] In the embodiments of this utility model, reference is made to Figure 3 As shown, the number of the first lifting cylinder 27 is the same as the number of the first drive slot 46, and there are multiple first lifting cylinders 27. The number of the second lifting cylinder 30 is the same as the number of the second drive slot 47, and there are multiple second lifting cylinders 30.

[0041] It should be noted that by setting the first drive groove 46, the first lifting cylinder 27 can be located inside the first drive groove 46 during use. When it is at its lowest position, the bottom of the first support plate 5 can abut against the bottom of the first lifting groove 26. Without affecting the lifting, the external space occupied by the first support plate 5 is reduced, improving the convenience of the device during use. Similarly, by setting the second drive groove 47, the external space occupied by the second support plate 20 can be reduced without affecting the lifting. Furthermore, by setting multiple first lifting cylinders 27 and second lifting cylinders 30, the force on the first support plate 5 or the second support plate 20 is made uniform, improving the stability of the first support plate 5 and the second support plate 20 when moving up and down.

[0042] In the embodiments of this utility model, reference is made to Figure 4 , Figure 5 As shown, the outer surface of the first support plate 5 is provided with a plurality of first guide blocks 38, the first guide blocks 38 are slidably connected to the first guide groove 28, the first guide groove 28 is disposed on the inner surface of the first lifting groove 26, the outer surface of the second support plate 20 is provided with a plurality of second guide blocks 45, the second guide blocks 45 are slidably connected to the second guide groove 31, the second guide groove 31 is disposed on the inner surface of the second lifting groove 29.

[0043] It should be noted that by setting the first guide block 38, the stability of the first support plate 5 when it moves up and down can be improved by the limiting guidance of the first guide groove 28. Similarly, by setting the second guide block 45, the stability of the first and second support plates when they move up and down can be improved by the limiting guidance of the second guide groove 31.

[0044] In the embodiments of this utility model, reference is made to Figure 4 , Figure 5 As shown, a first buffer pad 35 and a second buffer pad 42 are respectively bonded to the inner sides of the first clamping plate 34 and the second clamping plate 41, and the first buffer pad 35 and the second buffer pad 42 are made of rubber.

[0045] It should be noted that by setting the first buffer pad 35 and the second buffer pad 42 made of rubber, when clamping the drive mechanism, the deformation of the first buffer pad 35 and the second buffer pad 42 can fit tightly against the outer wall of the two ends of the drive mechanism, thereby increasing the friction coefficient between the corresponding clamping plate and the end of the drive mechanism, and thus improving the stability of the clamping plate when clamping and fixing the end of the drive mechanism.

[0046] In the embodiments of this utility model, reference is made to Figure 1 As shown, the number of the first moving slot 2 and the second moving slot 17 are the same, and the number of the first moving slot 2 is multiple.

[0047] It should be noted that by setting multiple first moving slots 2 and second moving slots 17, and installing first slide rails 3 and second slide rails 18 therein, the force on the bottom of the first support base 4 and the second support base 19 can be increased through the multiple first slide rails 3 and second slide rails 18, thereby facilitating the movement of the first support base 4 and the second support base 19.

[0048] In the embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, the bottom ends of the first support base 4 are respectively provided with a first left limiting plate 10 and a first right limiting plate 12. The first left limiting plate 10 and the first right limiting plate 12 are respectively slidably connected to the first left limiting groove 9 and the first right limiting groove 11. The first left limiting groove 9 and the first right limiting groove 11 are located on the top of the base 1 on both sides of the first moving groove 2. The bottom ends of the second support base 19 are respectively provided with a second left limiting plate 22 and a second right limiting plate 24. The second left limiting plate 22 and the second right limiting plate 24 are respectively slidably connected to the second left limiting groove 21 and the second right limiting groove 23. The second left limiting groove 21 and the second right limiting groove 23 are located on the top of the base 1 on both sides of the second moving groove 17.

[0049] It should be noted that by setting the first left limiting plate 10 and the first right limiting plate 12, the stability of the first support base 4's forward and backward movement is improved by the guidance of the first left limiting groove 9 and the first right limiting groove 11. Similarly, by setting the second left limiting plate 22 and the second right limiting plate 24, the stability of the second support base 19's forward and backward movement is improved by the guidance of the second left limiting groove 21 and the second right limiting groove 23.

[0050] The working principle of the maintenance and repair device for the turbine drive mechanism of a thermal power plant provided by this utility model is as follows:

[0051] By setting up a first lifting cylinder 27 and a second lifting cylinder 30, the height of the first support plate 5 and the second support plate 20 can be adjusted by extending and retracting the first lifting cylinder 27 and the second lifting cylinder 30. The height of the first support plate 5 and the second support plate 20 can be adjusted according to different sizes of drive mechanisms, which is convenient to adapt to different sizes of drive mechanisms and improves the applicability of the device. By setting up a first motor 7 and a second motor 15, the first rotating plate 6 and the second rotating plate 13 can be rotated by the first motor 7 and the second motor 15, thereby realizing the rotation of the drive mechanism clamped between the first rotating plate 6 and the second rotating plate 13, changing the orientation of the drive mechanism, which is convenient for detecting different positions of the drive mechanism. Moreover, the drive by the first motor 7 and the second motor 15 is different from the drive motor driving the drive gear, driving the mating gear and the mounting plate. This reduces the complexity of the overall structure and can effectively improve the service life.

[0052] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
