[0002] Various types of electrical control cabinets for locomotives are essential key equipment during the operation of locomotives, which contain a large number of complex electrical components and control circuits inside. During daily maintenance and repair, operators need to frequently disassemble and install the protection cover plates (doors) of various types of electrical control cabinets for locomotives in order to detect and repair the internal electrical equipment.

[0003] However, the existing protection cover plates are usually fixed by fasteners such as bolts and nuts, and have the following disadvantages: First, the operation process is cumbersome. When disassembling and assembling, it is necessary to use tools to remove multiple screws fixing the protection cover plate, and there are many operation steps. Each disassembly and assembly inspection takes about 3 hours, and the workload is large. Second, the working space is narrow. Since various types of electrical control cabinets for locomotives are usually installed in the locomotive machinery room, and the space in the locomotive machinery room is relatively narrow. It is difficult to disassemble and assemble the protection cover plate with cumbersome steps in a narrow space, especially the protection cover plate at the bottommost end, where the space is even narrower and it is not easy to disassemble and assemble. Especially in winter, due to wearing heavy clothes, the operation difficulty is even greater, which increases the difficulty of overhauling the internal electrical equipment of various types of electrical control cabinets for locomotives.

[0021] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0022] As Figures 1-4 shown, a detection and protection cover plate for various types of electrical control cabinets of the locomotive includes a frame 1 of various types of electrical control cabinets of the locomotive fixedly connected to the locomotive. Preferably, four protection cover plates are fixedly connected to one electrical control cabinet of the locomotive as a group, and its fixing method is preferably screw connection. Inside the frame 1 of various types of electrical control cabinets of the locomotive, there is installed a cabinet door 3 of various types of electrical control cabinets of the locomotive. One side of the cabinet door 3 of various types of electrical control cabinets of the locomotive is movably connected to the frame 1 of various types of electrical control cabinets of the locomotive, and its rotational connection method can be hinge connection, plug connection or rotating rod connection. A cabinet door lock 6 is installed on the cabinet door 3 of various types of electrical control cabinets of the locomotive. At this time, when the cabinet door 3 of various types of electrical control cabinets of the locomotive is closed, the cabinet door 3 of various types of electrical control cabinets of the locomotive is locked by the cabinet door lock 6, so that the electrical control cabinets of various types of locomotives can be hermetically protected. When it is necessary to repair the inside of the electrical control cabinets of various types of locomotives, unlock the cabinet door lock 6, and then open the cabinet door 3 of various types of electrical control cabinets of the locomotive to repair the inside of the electrical control cabinets of various types of locomotives. Since its opening method is relatively simple, it simplifies the operation steps of the operator in the narrow locomotive mechanical room, and can facilitate the operator to repair the electrical equipment inside the electrical control cabinets of various types of locomotives in a narrow space, improving the repair efficiency and reducing the discomfort brought to the operator by long-term repair work in the narrow locomotive mechanical room.

[0023] Among them, as Figures 2-3As shown in the figure, on the upper side of the door frame 1 of each type of locomotive electrical control cabinet, an additional door frame 2 of each type of locomotive electrical control cabinet is fixedly connected. The additional door frame 2 of each type of locomotive electrical control cabinet faces the instrument of each type of locomotive electrical control cabinet. Inside the additional door frame 2 of each type of locomotive electrical control cabinet, an additional cabinet door 4 of each type of locomotive electrical control cabinet is installed. One side of the additional cabinet door 4 of each type of locomotive electrical control cabinet is movably connected to the additional door frame 2 of each type of locomotive electrical control cabinet, and the rotational connection method can be hinge connection, plug-in connection or rotating rod connection. A cabinet door lock 6 is installed on the additional cabinet door 4 of each type of locomotive electrical control cabinet. At this time, when the additional cabinet door 4 of each type of locomotive electrical control cabinet is closed, the additional cabinet door 4 of each type of locomotive electrical control cabinet is locked through the cabinet door lock 6. When performing maintenance on the instrument of each type of locomotive electrical control cabinet, unlock the cabinet door lock 6, and then open the additional cabinet door 4 of each type of locomotive electrical control cabinet to perform maintenance on the instrument of each type of locomotive electrical control cabinet. Thus, when only performing maintenance on the instrument, only the relatively small-sized additional cabinet door 4 of each type of locomotive electrical control cabinet needs to be opened, reducing the occupation of the narrow space inside the locomotive electrical control room by the cabinet door, and thus enabling the operator to more conveniently perform maintenance operations on each type of locomotive electrical control cabinet inside the narrow locomotive mechanical room.

[0024] Among them, the connection method between the door frame 1 of each type of locomotive electrical control cabinet and the cabinet door 3 of each type of locomotive electrical control cabinet is preferably plug-in connection, and the connection method between the additional door frame 2 of each type of locomotive electrical control cabinet and the additional cabinet door 4 of each type of locomotive electrical control cabinet is also preferably plug-in connection;

[0025] Plug-in connection means that a U-shaped card is fixedly connected to the door frame 1 of each type of locomotive electrical control cabinet or the additional door frame 2 of each type of locomotive electrical control cabinet, and an L-shaped plug board is fixedly connected to the cabinet door 3 of each type of locomotive electrical control cabinet or the additional cabinet door 4 of each type of locomotive electrical control cabinet. The L-shaped plug board can be directly plugged into the inside of the U-shaped card to complete the plug-in connection. At this time, the cabinet door 3 of each type of locomotive electrical control cabinet or the additional cabinet door 4 of each type of locomotive electrical control cabinet can be directly horizontally moved, and the L-shaped plug board is pulled out from the inside of the U-shaped card to complete the disassembly of the cabinet door, so that the disassembly inside the narrow space of the cabinet door can be relatively simply completed.

[0026] Specifically, rotating rods are fixedly connected to one side of the upper and lower sides of the cabinet door 3 of each type of locomotive electrical control cabinet and the additional cabinet door 4 of each type of locomotive electrical control cabinet. The hinge, plug-in connection or rotating rod connection on the cabinet door 3 of each type of locomotive electrical control cabinet is inside the door frame 1 of each type of locomotive electrical control cabinet, and the hinge, plug-in connection or rotating rod of the additional cabinet door 4 of each type of locomotive electrical control cabinet is rotatably connected inside the additional door frame 2 of each type of locomotive electrical control cabinet.

[0027] Such as Figures 2-3As shown, the additional door frame 2 of various types of electrical control cabinets for locomotives is fixedly connected to one side of the upper side of the door frame 1 of various types of electrical control cabinets for locomotives, so that an empty area is provided on the upper side of the door frame 1 of various types of electrical control cabinets for locomotives and on one side of the additional door frame 2 of various types of electrical control cabinets for locomotives, and the empty area is opposite to the cables of various types of electrical control cabinets for locomotives, so that the protective cover (door) can be displaced from the cable after installation, so that the cable is directly exposed, which is convenient for operators to inspect and repair the cable.

[0028] Among them, Figures 2-3 As shown, the cabinet door 3 of the locomotive electrical control cabinet and the additional cabinet door 4 of the locomotive electrical control cabinet are both provided with an installation slot 7, and a mounting shell 5 is installed inside the mounting slot 7, and an edge plate is fixedly connected to the peripheral side of the mounting shell 5, and the edge plate is fixedly connected to the outer side of the cabinet door 3 of the locomotive electrical control cabinet or the additional cabinet door 4 of the locomotive electrical control cabinet, and the fixing method can be screw connection, and the cabinet door lock 6 is assembled on the mounting shell 5. At this time, when the cabinet door lock 6 is damaged, the cabinet door lock 6 can be replaced by disassembling the mounting shell 5, so that after the cabinet door lock 6 is damaged, there is no need to replace the cabinet door 3 of the locomotive electrical control cabinet or the additional cabinet door 4 of the locomotive electrical control cabinet, which is convenient for replacing the cabinet door lock 6 in a narrow locomotive machinery room.

[0029] Among them, Figures 2-4 As shown, the cabinet door lock 6 includes a lock core 9 installed on the mounting shell 5, and a lock tongue 10 is installed at one end of the lock core 9 located on the inner side of the mounting shell 5, and a handle 8 is installed at one end of the lock core 9 located on the outer side of the mounting shell 5. At this time, when the handle 8 is rotated, the lock tongue 10 can be driven to rotate through the lock core 9, so that the lock tongue 10 and the door frame 1 of the locomotive electrical control cabinet or the additional door frame 2 of the locomotive electrical control cabinet are opposite to each other, and locking can be completed. When the lock tongue 10 is rotated to be offset from the door frame 1 of the locomotive electrical control cabinet or the additional door frame 2 of the locomotive electrical control cabinet, unlocking can be completed.

[0030] The handle 8 is preferably rotatably connected to the lock cylinder 9. At this time, by rotating the handle 8, the handle 8 is rotated to the inside of the mounting shell 5 for placement, which can reduce the phenomenon that the operator accidentally touches the handle 8 when moving in the locomotive machinery room.

[0031] The door frames 1 of various types of electrical control cabinets for locomotives, the additional door frames 2 of various types of electrical control cabinets for locomotives, the cabinet doors 3 of various types of electrical control cabinets for locomotives and the additional cabinet doors 4 of various types of electrical control cabinets for locomotives are all made of a plate with a thickness of 1.5mm. The door frames 1 of various types of electrical control cabinets for locomotives are 850mm high, 510mm wide and 22.2mm thick. The cabinet doors 3 of various types of electrical control cabinets for locomotives are 765mm high and 452mm wide.

[0032] The height of the additional door frame 2 of each type of locomotive electrical control cabinet is 220 mm, the width is 285 mm, and the thickness is 22.2 mm. The height of the additional cabinet door 4 of each type of locomotive electrical control cabinet is 168 mm, and the width is 223.2 mm.

[0033] The working principle of the present utility model is as follows: When it is necessary to repair the inside of each type of locomotive electrical control cabinet, unlock the cabinet door lock 6, and then open the cabinet door 3 of each type of locomotive electrical control cabinet to repair the inside of each type of locomotive electrical control cabinet. After the repair is completed, close the cabinet door 3 of each type of locomotive electrical control cabinet, and then lock the cabinet door 3 of each type of locomotive electrical control cabinet through the cabinet door lock 6 to provide sealing protection for each type of locomotive electrical control cabinet;

[0034] In summary, by simplifying the disassembly and assembly method of the protective cover plate, this technical solution can simplify the operation steps of the operator inside the narrow locomotive electrical control room of each type, facilitate the operator to repair the electrical equipment inside the locomotive electrical control cabinet of each type in a narrow space, improve the repair efficiency, reduce the discomfort caused by the operator's long-term repair work in the narrow locomotive machinery room, reduce the workload, and has received favorable comments from front-line workers.

[0035] The above are only the preferred embodiments of the present utility model.
