Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of generator turning gear, specifically relating to generator turning gear device. Background Technology
[0002] In recent years, generator turning gears have become core auxiliary equipment in the installation, inspection and maintenance of generator sets.

With the assistance of operators, they can help the generator to operate normally.
[0003] Currently, the combination of the turning device and the drive equipment can help the generator rotor to perform operations such as calibration. Before the gear drives the rotor, the staff usually fills the lubricating oil at the meshing position of the gear and the rotor. If the staff forgets to perform the lubrication operation, the friction coefficient between the gear and the rotor will increase, which will cause abnormal wear or cylinder scoring after long-term use.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Example 1
[0027] Reference Figures 1-5This is the first embodiment of the present invention. This embodiment provides a generator turning device, including an oil injection component, including a turning device 10. A rotating shaft 11 is rotatably connected to the surface of the turning device 10. A gear 12 is fixedly connected to the surface of the rotating shaft 11. A liquid storage tank 13 is fixedly connected to the surface of the turning device 10. A baffle 14 is rotatably connected to the upper side of the liquid storage tank 13. An oil injection pipe 15 is fixedly connected to the lower side of the liquid storage tank 13. A stamping assembly 16 is provided between the rotating shaft 11 and the liquid storage tank 13. A telescopic assembly 17 is provided in the stamping assembly 16.
[0028] The rotating gear 10 has a groove on its surface, which helps to connect the rotating gear 10 to the drive device. The drive device makes the rotating shaft 11 rotate, which in turn drives the generator rotor to rotate in conjunction with the gear 12. At the same time, the liquid storage tank 13 can be filled with lubricating oil, and in conjunction with the stamping assembly 16, it can automatically realize the lubricating oil application operation in the meshing area.
[0029] Furthermore, the stamping assembly 16 includes a telescopic sleeve 161 fixedly connected to the upper side of the liquid storage tank 13. A top plate 162 is fixedly connected to the upper side of the telescopic sleeve 161. A drive ring 163 is fixedly connected to the surface of the rotating shaft 11. A slide plate 164 is slidably connected to the surface of the drive ring 163. An inclined plate 165 is fixedly connected to the side of the slide plate 164 away from the drive ring 163. The inclined surface of the inclined plate 165 is adapted to the inclined surface of the top plate 162. The telescopic assembly 17 includes two circular grooves 171 formed on the surface of the drive ring 163. A round rod 172 is fixedly connected to the inner wall of each of the two circular grooves 171. The end of the round rod 172 away from the circular groove 171 is fixedly connected to the inclined plate 165. A first spring 173 is sleeved on the surface of the round rod 172. The two ends of the first spring 173 are fixedly connected to the drive ring 163 and the inclined plate 165, respectively.
[0030] When the rotating shaft 11 rotates, it can work with the drive ring 163 to drive the inclined block closer to the top plate 162, thereby compressing the telescopic sleeve 161. This allows air pressure to be applied to help the lubricating oil be sprayed through the oil injection pipe 15 to the gear 12 and the generator meshing position, automatically completing the oil injection operation. The round rod 172, in conjunction with the spring, can improve the tightness of the inclined plate 165 close to the top plate 162, thereby improving the compression effect. At the same time, when pressing, the first spring 173 is compressed and enters the inner wall of the circular groove 171. At this time, dirt will not enter the position of the first spring 173, thus preventing jamming and facilitating the smooth pressing use of the first spring 173.
[0031] Preferably, the surface of the baffle 14 is provided with a circular hole, which is adapted to the feeding hole on the upper side of the liquid storage tank 13. A conical nozzle 151 is fixedly connected to the upper end of the fuel injection pipe 15, and five segmented plates 152 are linearly arranged on the inner wall of the fuel injection pipe 15. The surface of the segmented plates 152 is provided with a cross groove.
[0032] It should be noted that when the round hole and the feeding hole are on the same vertical line, the feeding operation can be performed. When the round hole is far away from the feeding hole, the feeding hole position can be sealed to prevent dust from entering and will not affect the use of the stamping assembly 16. The conical nozzle 151 can limit the lubricating oil so that the lubricating oil will not be discharged from the oil spray pipe 15 when it is not under pressure. When the lubricating oil is sprayed out from the inside of the oil spray pipe 15 by the segment plate 152, the lubricating oil can be sprayed out in segments, which can apply lubricating oil to multiple positions of the gear teeth 12 and improve the oiling effect.
[0033] In use, the drive device connects to the slot on the surface of the turning gear 10 to the rotating shaft 11 to achieve a driving effect, thereby driving the gear 12 to mesh and rotate with the generator shaft 11. At this time, the operator needs to rotate the baffle 14 in advance so that the opening on the surface of the baffle 14 aligns with the feeding hole, and then feed the lubricating oil into the liquid storage tank 13. Then rotate the opening away from the feeding hole and start the drive device. The drive device drives the rotating shaft 11 and the gear 12 to rotate. When the rotating shaft 11 drives the drive ring 163 and the inclined plate 165 on the surface to abut against the inclined surface of the top plate 162, the first spring 173 will press against the inclined block, improving the tightness of the inclined block and the top plate 162. As the drive ring 163 continues to rotate, it can compress the telescopic sleeve 161, which then affects the liquid storage tank. The internal pressure of the housing 13 helps open the conical nozzle 151 on the upper side of the oil injection pipe 15, allowing lubricating oil to flow into the oil injection pipe 15. At the same time, it drives the lubricating oil through the segmented plate 152. The segmented plate 152 opens under pressure and the impact of the lubricating oil to help the lubricating oil flow. Through the effect of the five segmented plates 152, the sprayed lubricating oil can be segmented, so that the lubricating oil can be sprayed to the tooth area of the gear 12 at different positions, improving the coating effect and reducing the waste of lubricating oil. By rotating the shaft 11 and cooperating with the stamping assembly 16, the lubricating oil spraying effect can be automatically completed when the turning device is working, without the need for manual spraying by the operator. This improves the smoothness of rotation between the gear 12 and the generator rotor, thereby improving the service life of the parts.
[0034] Example 2
[0035] Reference Figures 1-6This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a reminder component, including a central rod 20 fixedly connected to the inner wall of the liquid storage tank 13. A pusher frame 21 is slidably connected to the surface of the central rod 20, and a rotating block 22 is slidably connected to the surface of the central rod 20. Four guide plates 23 are fixedly connected to the arc surface of the rotating block 22. Pull ropes 24 are fixedly connected to the lower side of each of the four guide plates 23. A float ball 25 is fixedly connected to the lower end of the pull rope 24. A reset component 27 is provided between the rotating block 22 and the central rod 20. The reset component 27 includes a bottom frame 271 rotatably connected to the lower end of the central rod 20. A top frame 272 is slidably connected to the inner wall of the bottom frame 271. The upper end of the top frame 272 is rotatably connected to the lower end of the rotating block 22. A second spring 273 is sleeved on the surface of the central rod 20. The two ends of the second spring 273 are fixedly connected to the bottom frame 271 and the top frame 272, respectively.
[0036] Specifically, when the inclined plate 165, together with the top plate 162, compresses the telescopic sleeve 161, it can push the push frame 21, which in turn drives the rotating block 22 to slide down. When the lubricating oil is lower than the position of the float 25, it will drive the float 25 to slide up, which will produce a knocking effect and thus emit a warning sound to alert the operator.
[0037] Preferably, the upper side of the pusher frame 21 is L-shaped, and the upper end of the pusher frame 21 is fixedly connected to the lower side of the top plate 162. The surface of the center rod 20 is provided with a threaded groove 26, the inner wall of the rotating block 22 has a protrusion, and the protrusion is located inside the threaded groove 26. All four guide plates 23 are inclined.
[0038] It should be noted that the push frame 21 is connected in series with the top plate 162 and, together with the center rod 20, can limit the sliding direction of the push frame 21, so that the push frame 21 can slide smoothly vertically. The protrusion of the rotating block 22 is located inside the threaded groove 26. When the rotating block 22 slides down, it can drive the rotating block 22 to rotate. At this time, the inclined guide plate 23 can generate a downward guiding vortex, which improves the guiding effect of lubricating oil and facilitates the flow of lubricating oil from the oil injection pipe 15. Moreover, when the lubricating oil is lower than the float 25, it can work with the pull rope 24 to swing the float 25, which improves the knocking effect and increases the knocking prompt sound.
[0039] In use, when the telescopic sleeve 161 is pressed down to help the lubricating oil flow from the inside of the reservoir 13 through the injection pipe 15, it will drive the pusher 21 to slide down synchronously. In turn, the pusher 21 can push the rotating block 22 down. At this time, the rotating block 22, in conjunction with the protrusion on the inner wall, can move along the threaded groove 26, thereby producing a rotational effect. With the inclined guide plate 23, a central spiral can be generated, which can help the lubricating oil concentrate in the middle position and flow towards the conical nozzle 151. If the lubricating oil inside the reservoir 13 is higher than the float 25, the float 25 will float with the height of the lubricating oil. At this time, the float 25 will not impact or collide with the inside of the reservoir 13. If the lubricating oil level is below the float 25, when the rotating block 22 rotates, it will work with the pull rope 24 to cause the float 25 to swing, which will then collide with the inner wall of the reservoir 13, thus making a sound to alert the operator. The operator can then understand the remaining lubricating oil level and replenish it. During the turning operation, the lubrication spraying operation can be continuously performed on the meshing area. When the inclined block moves away from the pressure on the top plate 162, the second spring 273 will drive the rotating block 22 to slide up and reset, and drive the push frame 21 to slide up, which can assist the telescopic sleeve 161 to reset, making it convenient to perform the lubricating oil spraying operation again.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
