Abstract
Description
Technical Field
[0001] This utility model relates to the field of diesel engine technology, specifically to an oil pan that is easy to inspect and maintain. Background Technology
[0002] The existing mine car road conditions are poor, with many gravel and mud pits in the mining area, which easily leads to accidents such as flying stone impacts, causing damage or wear to various parts of the mine car and requiring frequent repairs or maintenance. When inspecting the internal components of the diesel engine, it is necessary to completely disassemble the oil pan, but the oil pan is too large, which is not conducive to complete disassembly, and the disassembly and reassembly time is long, increasing time costs. Utility Model Content
[0003] The technical problem this invention aims to solve is the difficulty in disassembling and maintaining the oil pan of existing mine car diesel engines.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is to provide an oil pan that is easy to inspect and maintain, including an oil pan and a pull rod. The oil pan includes a shallow section and a deep section, and an elastically deformable corrugated section is provided between the shallow section and the deep section. A rotating shaft is provided on the outer side of the deep section near the corrugated section, and a fixing bolt is provided on the outer side of the shallow section near the corrugated section. The rotating shaft and the fixing bolt are located on the same side. One end of the pull rod is fixed to the side of the shallow section by the fixing bolt. A pull rod hole is provided in the middle of the pull rod, and the pull rod hole is sleeved on the rotating shaft.
[0005] Optionally, an impact-resistant plate is provided on the outer surface of the deep section of the oil pan.
[0006] Optionally, the bottom of the oil pan is provided with an oil drain port, and the oil drain port is provided with a plug.
[0007] Optionally, the oil pan has a protrusion on its side, and the protrusion has a plug.
[0008] In summary, this utility model features a corrugated section on the oil pan. During inspection and maintenance, it is only necessary to remove the fixing screws of the shallow section and then pull the lever to open the shallow section, which facilitates internal maintenance and inspection. The operation is convenient and quick, saving time and costs. Furthermore, the anti-impact plate on the side of the oil pan can reduce the impact of flying stones on the oil pan and extend its service life. Attached Figure Description

[0012] The following combination Figure 1-2 The present invention will be described in further detail below.
[0013] This utility model discloses an oil pan that is easy to inspect and maintain, referring to... Figure 1 The oil pan 1 includes an oil pan 1 and a pull rod 7. The oil pan 1 includes a shallow section 2 and a deep section 3. A corrugated section 4 is provided between the shallow section 2 and the deep section 3. The corrugated section 4 is made of copper alloy and can be elastically deformed. A rotating shaft 5 is provided on the outer side of the deep section 3 near the corrugated section 4. A fixing bolt 6 is provided on the outer side of the shallow section 2 near the corrugated section 4. The rotating shaft 5 and the fixing bolt 6 are located on the same side. One end of the pull rod 7 is fixed to the side of the shallow section 2 by the fixing bolt 6. A pull rod hole is provided in the middle of the pull rod 7. The pull rod hole is fitted onto the rotating shaft 5. The pull rod 7 can rotate around the rotating shaft 5. An anti-impact plate 8 is provided on the outer side of the deep section 3 of the oil pan 1.
[0014] Specifically, the tie rod 7 can be a straight rod or an angled V-shaped rod. The position of the fixing bolt 6 can be higher than or flush with the rotating shaft 5, as long as the tie rod 7 can drive the shallow section 2 to open. The anti-impact plate 8 is mainly set on one side of the mine car in the direction of travel, but it can also be set on other sides to avoid the impact of flying stones caused by other vehicles.
[0015] In a further embodiment, the oil pan 1 has an oil drain port 9 at the bottom, and a plug 10 is provided on the oil drain port 9. The oil pan 1 has a protrusion on the side, and a plug 10 is provided on the protrusion, so as to facilitate the replacement of the plug 10 on the oil drain port 9.
[0016] When using this utility model, refer to Figure 2 Remove the bolts connecting the shallow section 2 to the mine car diesel engine, then pull the lever 7 upwards. The shallow section 2 of the oil pan 1 will open downwards, allowing for internal inspection or maintenance. After inspection, pull the lever 7 downwards to close the shallow section 2, and tighten the bolts to complete the installation. The operation is simple and quick.
[0017] 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.
