Description

Technical Field

[0001] This utility model relates to the field of pitch gear maintenance technology, and in particular to a waste oil cleaning shovel for yaw pitch gears. Background Technology

[0002] The yaw and pitch transmission gears of wind turbines use both automatic and manual lubrication methods. With automatic lubrication, if waste oil is not cleaned in time, it will accumulate and cause switch malfunctions. Moreover, long-term accumulation will cause waste oil to overflow and contaminate the nacelle and tower. Manual lubrication requires regular manual application of lubricating oil, and the oil applied last time needs to be cleaned up before each application. Therefore, both lubrication methods require cleaning of waste oil on the gears.

[0003] Currently, cleaning is done manually. However, the waste oil applied manually dries and hardens over time, making it difficult to remove. Furthermore, the workspace is small, requiring workers to squat, and the work environment is harsh in winter due to the low temperature at the air vents at the bottom of the engine room. The lack of specialized tools further complicates the process, resulting in slow cleaning efficiency. Additionally, after cleaning, manual application of grease is still required on the pitch gear ring, which is inefficient and time-consuming. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] Please refer to Figure 1-5 The technical solution of this utility model is a waste oil cleaning shovel for yaw and pitch gears, comprising:

[0028] Handle 1;

[0029] The shovel head 2 is detachably and fixedly connected to the handle 1, and includes multiple shovel teeth 20. The side 200 of the shovel teeth 20 is provided with multiple oil outlet channels 25.

[0030] The connecting pipe 21 is disposed on the shovel head 2 and is connected to the oil outlet channel 25 on the plurality of shovel heads 2.

[0031] Specifically, this application provides a waste oil cleaning shovel for yaw and pitch gears, the specific structure of which includes: a handle 1, as shown in the reference. Figure 9The handle 1 has two parallel and spaced connecting plates 10 integrally formed at its end. The shovel head 2 has a plate-shaped structure. One end of the shovel head 2 has shovel teeth 20, which are adapted to the size and module of the transmission teeth of the gear ring. Different shovel heads are adapted to different gear rings. At the end away from the shovel teeth 20, the shovel head 2 has a stepped groove that mates with the two connecting plates 10. Two through holes are drilled in the stepped groove. The connecting plate 10 is fitted with the two through holes to form a second through hole. When connecting the handle 1 and the shovel head 2, the connecting plate 10 is aligned with the stepped groove, and then the screw 11 is passed through the through hole and the second through hole in sequence to lock it, thereby realizing the connection between the handle 1 and the shovel head 2. Since the shovel head 2 is a consumable, this setting method facilitates the replacement of the shovel head 2, and also facilitates the replacement of the shovel head 2 when cleaning gear rings with different parameters. It should be noted that the screw 11 used in this application is a female screw 11.

[0032] Furthermore, the side 200 of the shovel tooth 20 is drilled with an oil outlet channel 25, and the shovel head 2 is equipped with a connecting pipe 21. With this arrangement, the connecting pipe 21 can be connected to the oil outlet of the electric grease gun. The connecting pipe 21 is a flexible pipe and is cut to an appropriate length as needed. Since the shovel tooth 20 is designed to match the tooth shape of the gear ring, when cleaning the yaw and pitch gear ring, the operator can hold the cleaning shovel in one hand and the electric grease gun in the other hand. The shovel head 2 is inserted into the transmission tooth gap of the gear ring to scrape and clean the waste oil on the gear ring from top to bottom or from bottom to top. After scraping and cleaning, the electric grease gun can be controlled to pump grease. The grease can flow out through the oil outlet channel 25 and adhere to the cleaned gear ring, thus performing the greaseing operation. Using a dedicated cleaning shovel can improve cleaning efficiency and greaseing efficiency, reduce operation time, and reduce the labor intensity of the operator.

[0033] It should be noted that electric grease guns are commonly used devices in this field, and for the sake of brevity, they will not be described in detail here, but those skilled in the art should be aware of them.

[0034] Furthermore, as a specific implementation method, refer to Figure 5 , Figure 7 , Figure 8The shovel head 2 has multiple first blind holes 22 corresponding to the teeth 20 on its side away from the teeth 20. Each first blind hole 22 communicates with an oil outlet channel 25, and all of the first blind holes 22 are interconnected. The connecting pipe 21 is connected to one of the first blind holes 22. Specifically, the shovel head 2 can be made of materials such as plastic, stainless steel, or aluminum alloy, with plastic and aluminum alloy being preferred. Plastic and aluminum alloy have low density, which can reduce the weight of the shovel head 2 and reduce the workload during use. This application drills a first blind hole 22 corresponding to each tooth 20 on the end face of the shovel head 2. Each first blind hole 22 communicates with multiple oil outlet channels 25 on the side 200 of each tooth 20. Then, a path connecting the multiple first blind holes 22 is set on the shovel head 2. This method only requires connecting the connecting pipe 21 to the end of one blind hole to achieve communication with the oil outlet channels 25 on all teeth 20. As a specific implementation method, refer to... Figure 1 , Figure 2 In use, a connector 23 is provided at the end of one of the first blind holes 22. The connecting pipe 21 is detachably connected to the connector 23. The oil pipe can be pressed and fixed to the handle 1 by the clamping plate 26. The ends of the other two first blind holes 22 can be blocked by the plug 24. The clamping plate 26 is detachably fixed to the handle by the screw 11.

[0035] Furthermore, as a specific implementation method, refer to Figure 2 , Figure 8 The side 200 of the shovel head 2 is provided with a second blind hole 240, which is intersected and connected with a plurality of first blind holes 22. The end of the second blind hole 240 is threadedly connected with a plug 24.

[0036] Furthermore, as a preferred embodiment, refer to Figures 5-7 The shovel head 2 has a plate-like structure. A recess 201 is provided on the first surface near the shovel head 2 and the side surface 200 of the shovel teeth 20. The oil outlet channel 25 is located in the recess 201. Specifically, the shovel head 2 is a plate-like component with two plate surfaces, namely the first surface and the second surface. By providing a recess 201 on the side surface 200 near the first surface, the shovel plate is moved from the first surface to the second surface during the scraping and cleaning of the gear ring. This reduces the contact area between the side surface 200 of the shovel teeth 20 and the transmission tooth surface during cleaning of the gear ring. Furthermore, when the grease flows out from the oil outlet channel 25, it can stay in the recess 201, forming a grease cavity. This method ensures the uniformity of oiling the gear ring.

[0037] Furthermore, as a preferred embodiment, the recessed portion 201 intersects with the first surface. By hinged the recessed portion 201 to the first surface, the contact area between the side surface 200 and the gear ring is further reduced, ensuring better contact between the remaining side surface 200 of the shovel tooth 20 and the transmission tooth surface, thereby achieving a better shoveling and cleaning effect.

[0038] Furthermore, a surrounding plate 203 is provided on the bottom surface of the recess 201 around the end of the oil outlet channel 25. The end face of the surrounding plate 203 is flush with the side surface 200, and a notch 204 is provided at the end of the surrounding plate 203. Specifically, refer to... Figure 5 , Figure 6 , Figure 8 Based on the intersection of the recessed portion 201 and the first surface, a surrounding plate 203 is set around the oil outlet channel 25 on the bottom surface of the recessed portion 201. The surrounding plate 203 is set in the middle area of ​​the side 200, and each side 200 of the scraper tooth 20 is provided with a recessed portion 201, a surrounding plate 203 and an oil outlet channel 25. During the scraping and cleaning operation, the end of the surrounding plate 203 is in contact with the transmission teeth of the tooth ring, and an oil storage cavity can be formed through the bottom surface of the surrounding plate 203 and the recessed portion 201 and the tooth surface of the transmission teeth. The grease is flowed out through the notch 204. The scraper head 2 moves while the grease is flowing out, thereby evenly applying the grease to the tooth surface of the transmission teeth. This method can further improve the uniformity of grease application.

[0039] Further, refer to Figure 6 The notch 204 can be set on both sides of the enclosure 203 near the first and second sides. Preferably, the notch 204 is set on the side of the enclosure 203 near the first side.

[0040] Furthermore, as a preferred embodiment, a plunger 12 is provided at the end of the handle 1, and the plunger 12 is inserted into and sealed with the end of the first blind hole 22. Specifically, the plunger 12 is integrally formed with the handle 1, and the handle 1 can be made of plastic. With this embodiment, after the handle 1 is installed on the shovel head 2, the plunger 12 can seal the end of the first blind hole 22 in the middle, reducing the number of times the blockage 24 is used, and the insertion of the plunger 12 and the first blind hole 22 can also form a positioning fit.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
