[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 8As shown, an embodiment of the present invention provides a hydropower station weight side relay maintenance platform 100, which includes a maintenance frame 10 and a fixed assembly 20. The maintenance frame 10 has a multi-layer truss structure. The maintenance frame 10 includes a plurality of connecting rods 11 and a plurality of adjustable locking members 12. The plurality of connecting rods 11 are connected to each other through the adjustable locking members 12. The fixed assembly 20 includes a length-adjustable top rod 21 and a length-adjustable lateral support rod 22. The length-adjustable top rod 21 and the length-adjustable lateral support rod are provided in plurality. The plurality of length-adjustable top rods 21 are arranged at intervals on the top of the maintenance frame 10. One end of the length-adjustable top rod 21 is connected to the maintenance frame 10, and the other end of the length-adjustable top rod 21 abuts against the weight bracket 220. The plurality of length-adjustable lateral support rods 22 are respectively provided on opposite sides of the maintenance frame 10. One end of the length-adjustable lateral support rod 22 is connected to the maintenance frame 10, and the other end of the length-adjustable lateral support rod 22 abuts against the side wall of the weight chamber.

[0031] Specifically, the hydropower station relay 200 is a key executive component of the speed control system, which is used to accurately control the opening of the turbine guide vanes, thereby adjusting the unit output. The weight side specifically refers to the installation area of ​​the relay counterweight system, which is usually provided with a weight bracket 220. The weight 210 is suspended on one side of the relay 200 body through the bracket. The weight side can also be called a weight room. The weight side relay refers to the relay located on one side of the weight. During the maintenance process of the weight side relay 200, the maintenance frame 10 adopts a multi-layer truss structure, which can be freely built in the weight room, and is supported at multiple points by the fixing assembly 20 to complete the installation and positioning of the maintenance platform.

[0032] Among them, the fixing component 20 can realize a two-dimensional adjustment mechanism through the length-adjustable top rod 21 and the length-adjustable lateral support rod 22. That is, the length-adjustable top rod 21 is arranged at the top of the maintenance frame 10, and the length of the length-adjustable top rod 21 is adjusted so that it abuts the top of the weight bracket 220, which can ensure the positioning of the maintenance frame 10 in the height direction. The length-adjustable lateral support rods 22 can be relatively arranged in the front-to-back direction or the left-to-right direction of the maintenance frame 10, and are arranged at intervals along the height direction of the maintenance frame 10, so as to form a multi-level support network and an effective support force, which effectively resists the tilt or shaking that may be caused by external forces or the deadweight of the platform, and ensures the safe progress of the maintenance work. In this embodiment, the length-adjustable lateral support rods are extended along the front-to-back direction of the maintenance frame.

[0033] In summary, the hydropower station hammer side relay maintenance platform 100 provided by the present invention can quickly and flexibly build a stable maintenance operation platform in the hammer room through the cooperation of the maintenance frame 10 and the fixing assembly 20. The maintenance platform can not only achieve precise docking with the hammer bracket 220 to ensure accurate positioning during the maintenance process, but also provide solid and reliable support for the entire maintenance operation through its unique fixing mechanism, effectively preventing any unstable factors during the operation process.

[0034] like Figure 2 and Figure 3 As shown, in this embodiment, the connecting rod 11 may include a column 111, a transverse rod 112 and a longitudinal rod 113, the column 111 is extended along the height direction of the maintenance frame 10, the transverse rod 112 is extended along the left and right direction of the maintenance frame 10, and the longitudinal rod 113 is arranged along the front and back direction of the maintenance frame 10. The column 111, the transverse rod 112 and the longitudinal rod 113 are assembled by an adjustable locking member 12 to complete the multi-layer truss structure.

[0035] like Figure 3 and Figure 4 As shown, the length-adjustable lateral support rod and the length-adjustable mandrel can have the same structure. That is, the length-adjustable lateral support rod and the length-adjustable mandrel both include a first rod barrel 231, a second rod barrel 232 and a threaded rod 233, and a sliding cavity 2311 is provided in the first rod barrel. One end of the second rod barrel is slidably arranged in the sliding cavity, and the other end of the second rod barrel is provided with an abutment seat 2321, and a rubber pad 2322 is provided on the abutment seat. A threaded sleeve 2312 is provided on the first rod barrel, and the threaded sleeve cooperates with the threaded rod, and one end of the threaded rod is connected to the second rod barrel. During the rotation of the threaded rod in the threaded sleeve, the threaded rod drives the second rod barrel to move relative to the first rod barrel. Of course, in some embodiments, the length-adjustable lateral support rod and the length-adjustable mandrel can also be set as other components such as a hydraulic rod, which will not be repeated here. It should be noted that in some embodiments, the length-adjustable lateral support rod and the length-adjustable mandrel can also be set as different structures.

[0036] like Figure 4 As shown, in some embodiments, the adjustable locking member 12 includes a connecting body 121, a positioning rod 122 and a locking rod 123. The connecting body 121 is provided with a through hole 1211 and a slot 1212. The through hole 1211 and the slot 1212 are used for inserting the connecting rod 11, and the straight line in the through hole 1211 where the connecting rod 11 extends and the straight line in the slot 1212 where the connecting rod 11 extends are staggered. The positioning rod 122 is connected to the inner wall of the through hole 1211 by a thread, and the end of the positioning rod 122 abuts against the connecting rod 11. The locking rod 123 is rotatably arranged at the mouth of the slot 1212, and the locking rod 123 is used to fix the connecting rod 11 in the slot 1212.

[0037] Specifically, when assembling two connecting rods 11 to be connected, one of the two connecting rods 11 can be inserted into the through hole 1211, and the positioning rod 122 can be tightened toward the connecting rod 11 in the through hole 1211 to fix it in the through hole 1211; the other of the two connecting rods 11 is inserted into the slot 1212, and the locking rod 123 can rotate relative to the mouth of the slot 1212 to block the mouth of the slot 1212, thereby fixing the connecting rod 11 in the slot 1212 to the slot 1212. The entire assembly process does not require complex tools or cumbersome steps, and can achieve a stable connection and flexible adjustment between the connecting rods 11, providing a strong support and adjustment capability for the maintenance frame 10 structure of the heavy hammer side relay maintenance platform 100 of the hydropower station.

[0038] In addition, the locking rod 123 is rotatably arranged at the mouth of the slot 1212. By rotating the locking rod 123, it can be accurately inserted into a specific position of the connecting rod 11 in the slot 1212, thereby achieving a secure locking of the connecting rod 11, which not only ensures the stability of the connecting rod 11 in the slot 1212, but also allows easy operation when adjustment or disassembly is required.

[0039] Furthermore, the locking rod 123 includes a first rod 1231 and a second rod 1232, the connecting body 121 has a first mouth 1213 and a second mouth 1214, the first mouth 1213 and the second mouth 1214 are relatively arranged on both sides of the slot 1212, the first rod 1231 is rotatably connected to the first mouth 1213, the first rod 1231 is provided with a socket 1233, the first rod 1231 and the second rod 1232 can be rotated towards or away from each other, one end of the second rod 1232 is rotatably connected to the second mouth 1214, and the other end of the second rod 1232 is inserted into the socket 1233.

[0040] Specifically, the first rod 1231 is firmly mounted on the first opening 1213 by means of a rotational connection, so that the first rod 1231 can rotate freely within a certain range to meet the fixing requirements of different connecting rods 11. A plug hole 1233 is cleverly provided on the first rod 1231, which not only provides a position for the insertion of the second rod 1232 and realizes the locking of the second rod, but also ensures that the connection between the second rod 1232 and the first rod 1231 is firm and reliable through its precise size and shape design.

[0041] One end of the second rod 1232 is installed at the second opening 1214 by means of a rotational connection, so that the second rod 1232 can also rotate freely within a certain range, forming a rotational relationship with the first rod 1231 facing or facing away from each other. When it is necessary to fix the connecting rod 11 in the slot 1212, the operator only needs to rotate the first rod 1231 and the second rod 1232 to rotate them toward each other until the other end of the second rod 1232 is accurately inserted into the insertion hole 1233 on the first rod 1231. At this time, the first rod 1231 and the second rod 1232 form a stable locking structure to firmly fix the connecting rod 11 in the slot 1212.

[0042] On the contrary, when the connecting rod 11 needs to be adjusted or disassembled, the operator only needs to rotate the first rod 1231 and the second rod 1232 in the opposite direction to rotate them backwards until the second rod 1232 is disengaged from the insertion hole 1233. At this time, the locking rod 123 loses the locking effect on the connecting rod 11, and the connecting rod 11 can be freely taken out of the slot 1212 or adjusted.

[0043] like Figure 1 Figure 2 and Figure 3 As shown, in some embodiments, the maintenance platform 100 of the weight-side servomotor of the hydropower station includes a plurality of pedals 31, which are arranged at intervals along the height direction of the maintenance frame 10, and a ladder 32 is provided between two adjacent layers of pedals 31. During the maintenance process, maintenance personnel can easily move between pedals 31 at different heights through these ladders 32, thereby achieving comprehensive maintenance and maintenance of various parts of the weight-side servomotor 200. That is, a plurality of pedals are arranged at intervals along the height direction of the maintenance frame 10 to form a plurality of rotating platforms in the height direction of the maintenance frame, so as to facilitate maintenance personnel to climb the maintenance frame.

[0044] Furthermore, the inspection frame 10 further includes a plurality of floor height support rods 33 and a plurality of floor height positioners 34, and the plurality of floor height support rods 33 are respectively arranged at opposite sides of the inspection frame 10. One end of the pedal 31 is connected to one of the two floor height support rods 33, and the other end of the pedal 31 is connected to the other of the floor height support rods 33. The floor height positioner 34 is fixed to the connecting rod 11 below the floor height support rod 33.

[0045] Furthermore, if Figure 5 As shown, the floor height locator 34 includes a fixing ring 341 and a positioning screw 342. A fixing cavity 343 is provided in the fixing ring 341. The connecting rod 11 is passed through the fixing cavity 343. The positioning screw 342 is rotatably passed through the side wall of the fixing cavity 343. The positioning screw 342 is used to abut the connecting rod 11 in the fixing cavity 343.

[0046] Specifically, a plurality of floor height support rods 33 are arranged on opposite sides of the maintenance frame 10, and they are grouped in pairs to form a stable support frame. These floor height support rods 33 not only support the pedal 31, but also cooperate with the floor height positioner 34 to achieve accurate and stable positioning of the pedal 31 in the height direction, thereby improving the safety during the maintenance process.

[0047] In addition, the hydropower station hammer side relay maintenance platform 100 provided by the present invention is safer than the fixing method of the pedal 31 straddling two longitudinal rods or transverse rods, and the adjustment of the spacing of the pedal 31 in the height direction is more convenient. In other words, when the height of the pedal 31 needs to be adjusted, the maintenance personnel need to operate the layer height support rod 33 and the layer height positioner 34 to achieve the lifting and fixing of the pedal 31, which not only ensures the safety of the maintenance platform, but also improves the flexibility and avoids the safety risks that may be caused by improper height adjustment.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the hydropower station hammer side relay maintenance platform 100 further includes at least one work platform 41, on which an extension plate 42 and a pressure rod 43 are provided, the extension plate 42 is arranged across the maintenance frame 10, and the length of the extension plate 42 is greater than the length or width of the maintenance frame 10, and both ends of the pressure rod 43 are connected to the connecting rod 11, and the pressure rod 43 is pressed on the extension plate 42. In this embodiment, two work platforms 41 are provided.

[0049] The extension plate 42 is arranged across the maintenance rack 10, which not only effectively expands the use area of ​​the workbench 41, but also provides a more flexible operating platform for maintenance personnel. It is worth noting that the length of the extension plate 42 is carefully calculated and specially designed to be greater than the length or width of the maintenance rack 10. Such a design allows the extension plate 42 to extend beyond the edge of the maintenance rack 10, providing great convenience for maintenance personnel when handling some components located at the edge of the maintenance rack 10 or at special positions.

[0050] When the maintenance personnel are working on the workbench 41, the pressure rod 43 can effectively prevent the extension plate 42 from shaking or shifting due to uneven force, thereby ensuring the smooth progress of the maintenance work. At the same time, the pressure rod 43 can also be fine-tuned according to the needs of the maintenance work to adapt to the extension plates 42 of different shapes and sizes, further enhancing the versatility and adaptability of the workbench 41.

[0051] Furthermore, if Figure 7As shown, the pressure rod 43 includes a rod body 431 and two locking members 432. The two locking members 432 are relatively arranged at the two ends of the rod body 431. The locking member 432 includes a locking ring 4321 and a locking rod 4322. The locking ring 4321 is provided with a locking cavity. The connecting rod 11 is inserted into the locking cavity. The locking rod 4322 is connected to the side wall of the locking cavity by a thread, and the locking rod 4322 abuts against the connecting rod 11 in the locking cavity.

[0052] Specifically, when the connecting rod 11 is inserted into the locking cavity, the locking rod 4322 plays its key locking role. The locking rod 4322 is firmly fixed to the side wall of the locking cavity by threaded connection, and one end of the locking rod 4322 can be tightly abutted against the connecting rod 11 in the locking cavity. By rotating the locking rod 4322, the position of the locking rod 4322 in the locking cavity can be fine-tuned, thereby achieving a stable locking of the connecting rod 11. This design not only ensures that the connection between the pressure rod 43 and the connecting rod 11 is stable and reliable, but also makes it easy to operate when the pressure rod 43 needs to be adjusted or disassembled.

[0053] In addition, it should be noted that in this embodiment, the floor height support rod 33 can have the same structure as the pressure rod 43, thereby simplifying the structural complexity of the entire maintenance platform and improving the versatility and interchangeability of components. The structure of the floor height support rod 33 will not be described in detail here.

[0054] like Figure 8 As shown, in some embodiments, the fixing assembly 20 also includes an adjustable cable 50, which includes a rope 51, a first cable rod 52, a second cable rod 53 and a tightening rod 54. The first cable rod 52 is connected to the maintenance frame 10 through the rope 51, and the second cable rod 53 is connected to the inner wall of the weight chamber through the rope 51. The first cable rod 52 and the second cable rod 53 are provided with external threads, and the tightening rod 54 is provided with an internal thread matching the external thread.

[0055] That is, when the maintenance platform needs to be built in the weight room, the operator can fine-tune the tension of the rope 51 by adjusting the position of the tightening rod 54, so that the adjustable cable 50 can fit tightly between the maintenance frame 10 and the inner wall of the weight room. This design not only enhances the stability of the maintenance platform in the weight room, but also allows the platform to be flexibly adjusted according to different space layouts and force requirements.

[0056] In addition, an embodiment of the present invention further provides a maintenance device for a weight-side servomotor 200 of a hydropower station, which includes a maintenance platform 100 for a weight-side servomotor of a hydropower station provided in any of the above embodiments. Among them, the maintenance device for a weight-side servomotor 200 of a hydropower station provided in the embodiment of the present application has the same implementation principle and technical effects as those of the above-mentioned maintenance platform 100 for a weight-side servomotor of a hydropower station. For the sake of brief description, for matters not mentioned in the device embodiment, reference may be made to the corresponding contents in the above-mentioned maintenance platform 100 for a weight-side servomotor of a hydropower station.

[0057] In some embodiments, the maintenance equipment of the heavy hammer side relay 200 of the hydropower station may also include components such as lighting and power supply, and the lighting and power supply may be arranged on the workbench 41 of the maintenance platform. Among them, the lighting can illuminate the maintenance area, provide sufficient light for the maintenance personnel, and avoid misoperation or safety hazards caused by insufficient light. The power supply provides stable power support for the lighting and other maintenance equipment that may be needed.
