Description

Technical Field

[0001] This utility model relates to the field of excavator maintenance technology, specifically to an oil draining device for the electric shovel's disc. Background Technology

[0002] During production operations of the WK-20 electric shovel, the central pivot is automatically lubricated every 15 minutes. The waste oil from lubrication is discharged and accumulates in the shovel's center plate, requiring manual cleaning. During maintenance time, it takes 3-4 people about 2 hours to manually clean this area. This presents technical problems such as limited space, inconvenience for workers to move around in the center plate, and time-consuming and labor-intensive tasks. Utility Model Content

[0003] The purpose of this utility model is to provide an oil draining device for the electric shovel's disc to solve at least one of the above-mentioned technical problems.

[0004] This utility model embodiment provides an oil draining device for the electric shovel's central plate, including: an oil draining ramp, a closed enclosure structure, and an oil tank. The oil draining ramp is disposed at the bottom of the central pivot of the electric shovel's central plate. The closed enclosure structure is arranged around the outer diameter of the central pivot of the electric shovel's central plate. The bottom of the closed enclosure structure is sealed to the oil draining ramp. The front end of the closed enclosure structure forms an oil drain hole with the through hole of the electric shovel's central plate. The oil tank is disposed at the bottom of the electric shovel's central plate, directly below the oil drain hole.

[0005] Optionally, the enclosed enclosure structure is composed of multiple baffles connected end to end.

[0006] Optionally, the baffle includes an iron plate, and the baffle is connected to the oil drainage slope by welding.

[0007] Optionally, the oil draining ramp forms a frustum-shaped ramp structure at the bottom of the central pivot of the electric shovel's disc.

[0008] This utility model provides an oil draining device for the electric shovel's central disc. By adding an oil draining track at the bottom of the central pivot of the electric shovel's central disc, the waste oil generated by the electric shovel is discharged into the oil tank through the oil draining hole by utilizing the fluidity of lithium-based grease. This can significantly improve the oil draining efficiency, reduce manual operation time, and alleviate the technical problems of inconvenience and time-consuming and laborious manual cleaning in the prior art. Attached Figure Description

[0009] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the specific embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this application. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0010] Figure 1 This is a schematic diagram of the structure of an oil draining device for an electric shovel, provided as an embodiment of the present invention.

[0011] In the diagram: 1. Oil drain slope, 2. Enclosed enclosure structure, 3. Oil drum, 4. Electric shovel center plate, 5. Central pivot, 6. Through hole, 7. Oil drain hole. Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Figure 1 This is a structural schematic diagram of an oil draining device for an electric shovel according to an embodiment of the present utility model. Figure 1 As shown, it includes: an oil draining ramp 1, a closed enclosure structure 2, and an oil drum 3. The oil draining ramp 1 is located at the bottom of the central pivot 5 of the electric shovel's middle plate 4. The closed enclosure structure 2 is arranged around the outer diameter of the central pivot 5 of the electric shovel's middle plate 4. The bottom of the closed enclosure structure 2 is sealed to the oil draining ramp 1. The front end of the closed enclosure structure 2 forms an oil drain hole 7 with the through hole 6 of the electric shovel's middle plate 4. The oil drum 3 is located at the bottom of the electric shovel's middle plate 4, directly below the oil drain hole 7.

[0014] Specifically, the enclosed enclosure structure 2 is composed of multiple baffles connected end to end. Optionally, the baffles include iron plates, and the baffles are connected to the oil drainage slope 1 by welding.

[0015] Optionally, the baffle is made of iron plate with a length of 3000mm, a height of 250mm, and a thickness of 8mm.

[0016] Specifically, such as Figure 1 As shown, the oil draining slope 1 forms a frustum-shaped slope structure at the bottom of the central pivot 5 of the electric shovel's disc 4.

[0017] This utility model provides an oil draining device for the electric shovel's central disc. Utilizing the fluidity of lithium-based grease, the waste oil from lubrication of the central pivot 5 flows freely on the drain slope 1, and then flows into the drain hole 7 under the constraint of the enclosed enclosure structure 2, ultimately being collected in the bottom oil tank 3. This achieves both cleaning of the electric shovel's central disc and ensures effective oil draining. Compared with the prior art, this utility model has the following technical advantages: 1. Significantly improved oil removal efficiency; 2. Achieve automatic oil draining, reducing manual intervention; 3. The sealed structure prevents leakage, enhancing safety and environmental protection while reducing manual labor.

[0018] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0019] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
