Description

Technical Field

[0001] This utility model relates to engines, and in particular to a protective cover device for a railway passenger car engine. Background Technology

[0002] Currently, most railway passenger cars use diesel engines as their power source, which drive generators to produce electricity. Diesel engines operate under harsh conditions and require regular maintenance. Faults during operation necessitate repairs. The diesel engine's fuel system has a relatively high failure rate. This system includes a high-pressure pump, high-pressure fuel lines, and fuel injectors. The plunger valves of the high-pressure pump and the components of the fuel injectors are precision parts. After prolonged operation, railway passenger cars accumulate a large amount of dust on their bodies. This dust is difficult to clean completely during maintenance and disassembly of the fuel system, and it easily enters the fuel system, affecting its normal operation and causing malfunctions. During major overhauls, the diesel engine needs to be removed from the passenger car. During hoisting, the components of the fuel system are easily damaged by impacts, increasing repair costs. Utility Model Content

[0003] The present invention aims to solve the above-mentioned technical problems, thereby providing a protective cover device for railway passenger car engines, improving the service life of the oil circuit system and reducing maintenance costs.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A protective cover for a railway passenger car engine includes a frame and a protective door. The protective door and the frame are hinged together by a hinge assembly. The protective door includes a door frame and a transparent panel, with the transparent panel embedded within the door frame.

[0006] The frame has an L-shaped cross-section. A first notch structure is provided on one vertical part of one end of the frame, and a second notch structure is provided on both vertical parts of the other end of the frame. A pipeline protection component is provided on the outer plate of the second notch structure, and an installation component for connecting to the engine is provided at each of the four corners inside the frame.

[0007] The protective door is a double-leaf structure, and a fixing component is provided between the two protective doors.

[0008] Compared with the prior art, the present invention, which adopts the above technical solution, has the following beneficial effects:

[0009] 1) The protective cover is installed on the top of the diesel engine to effectively protect the high-pressure pump, high-pressure fuel line and fuel injector of the fuel system, and prevent the components of the fuel system from being bumped or knocked.

[0010] 2) The protective cover device prevents dust from accumulating on the components of the oil circuit system. When the oil circuit system is being repaired, it prevents dust from entering the oil circuit system, thereby improving the service life of the oil circuit system and reducing the failure rate.

[0011] 3) During maintenance, the components of the oil circuit system can be disassembled by opening the protective door, making it convenient to use.

[0012] Furthermore, the optimized solution of this utility model is:

[0013] The frame is rectangular.

[0014] The first gap structure is rectangular.

[0015] The corners of the frame are chamfered.

[0016] The pipeline protection assembly includes a cylinder and a cap. The cylinder is semi-circular, and a semi-circular cap is provided at the upper end of the cylinder. A third circumferential notch structure is provided on one side of the cylinder wall.

[0017] The mounting assembly includes a fastener and a connector. The fastener is L-shaped and inclined inward. The inner end of the fastener is fixed to the inner plate surface of the chamfered structure. The inner end of the connector is detachably connected to the outer end of the fastener. The outer end of the connector has a fourth notch structure, which is bolted to the engine block.

[0018] The fastening component is a hook and loop fastener.

[0019] The transparent panel is made of glass or plexiglass. Attached Figure Description
