Description

Technical Field

[0001] This application relates to the field of locomotive technology, and in particular to locomotive frames and locomotives. Background Technology

[0002] In terms of spatial structure, a locomotive mainly consists of two parts: the locomotive frame and the engine room. The locomotive frame is used for the activity space of the driver and passengers. It is generally a closed structure with doors and windows. The equipment inside needs to be moved in manually, and large equipment cannot be placed inside. The engine room is full of equipment. In order to facilitate the hoisting of equipment, the top cover is generally set as a detachable movable cover. The movable cover has a relatively weak load-bearing capacity.

[0003] As traction vehicles for rail transit, locomotives require the installation of a large amount of equipment both inside and outside the vehicle, resulting in extremely limited space. Current technology typically involves exposing some equipment on the locomotive frame or above the engine room roof. However, due to clearance requirements, the height of the rooftop equipment must be as low as possible, making it impossible to install large equipment. Furthermore, equipment exposed on the roof not only affects the overall shape of the locomotive and increases air resistance, but also requires high levels of waterproofing and dustproofing. Summary of the Invention

[0004] Based on this, this application provides a locomotive frame and a locomotive to solve the problem in the related art that locomotives cannot install large equipment.

[0005] This application provides a locomotive frame, which includes: a top cover having a recessed platform; a cover plate covering the platform, with the outer edge of the cover plate located on the outer periphery of the platform to cover the platform, the cover plate and the platform together forming a cavity for placing equipment; and a first drainage structure including a first drainage trough disposed between the top cover and the cover plate.

[0006] In one embodiment, the locomotive frame further includes a second drainage structure, which includes a second drainage trough and a first drainage pipe. The second drainage trough is disposed within the platform and communicates with the first drainage pipe to drain water from the platform.

[0007] In one embodiment, the locomotive frame includes an annular retaining wall surrounding the outer periphery of the roof. The outer edge of the roof is connected to the upper edge of the annular retaining wall and together they form the cab. A first drain pipe is disposed on the annular retaining wall.

[0008] In one embodiment, the second drainage structure further includes a junction box, which is embedded in an annular retaining wall. The second drainage channel is connected to the junction box, and the junction box is connected to the first drainage pipe. The junction box includes a first drainage chamber and a second drainage chamber that are spaced apart. The second drainage channel is connected to the first drainage chamber. The second drainage structure also includes a second drainage pipe, which is connected to the second drainage chamber, and the second drainage chamber is connected to the equipment.

[0009] In one embodiment, the locomotive frame also includes a machinery compartment located on one side of the cab and attached to an annular retaining wall, the top surface of which is not higher than the bottom wall of the first drainage trough.

[0010] In one embodiment, the locomotive frame also includes a side panel surrounding the platform, the lower edge of the side panel being connected to the top cover, a cover plate covering the outer perimeter of the side panel, a partial annular retaining wall protruding from the top cover, and a first drainage ditch disposed between the side panel and the annular retaining wall.

[0011] In one embodiment, the top cover includes a connecting plate, a bottom plate, and a support frame. Connecting plates are provided on both sides of the bottom plate, and the bottom plate is recessed within the connecting plates. The outer edge of the connecting plates and the bottom plate are respectively connected to the inner wall of the annular retaining wall. The support frame is provided on the bottom plate and connected to the annular retaining wall.

[0012] In one embodiment, there are two second drainage channels and two first drainage pipes. The two second drainage channels are located on both sides of the settling platform, and the two second drainage channels and the two first drainage pipes are connected in a one-to-one correspondence.

[0013] In one embodiment, the top cover is further provided with a mounting base, which is located inside the recessed platform, and the top wall of the mounting base is higher than the bottom wall of the recessed platform.

[0014] In another aspect, this application provides a locomotive, which includes the locomotive frame provided above.

[0015] By applying the technical solution of this application, a recessed platform is provided on the top cover of the locomotive frame, and a cover plate is placed on the platform. The cover plate and the platform together form a cavity for placing the equipment, thus enabling the equipment to be placed within the cavity. The platform reduces the height of the equipment on the top cover.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] Figure 1 A partial structural schematic diagram of the locomotive frame provided in an embodiment of this application is shown. Figure 2 A schematic diagram of the locomotive frame provided in an embodiment of this application is shown. Figure 9 A top view of the locomotive frame provided in an embodiment of this application is shown. (In conjunction with...) Figure 1 , Figure 2 as well as Figure 9 As shown, one embodiment of this application provides a locomotive frame, which includes a top cover 10, a cover plate 20, and a first drainage structure 30. The top cover 10 has a recessed platform 11. The cover plate 20 covers the platform 11, with its outer edge located around the platform 11 to cover it. The cover plate 20 and the platform 11 together form a cavity for housing equipment. The first drainage structure 30 includes a first drainage channel 31, which is disposed between the top cover 10 and the cover plate 20.

[0040] By applying the technical solution of this application, a recessed platform 11 is provided in the top cover 10 of the locomotive frame, and a cover plate 20 is placed on the platform 11, so that the cover plate 20 and the platform 11 together form a cavity for placing equipment, thereby enabling the equipment to be placed in the cavity. The platform 11 reduces the height of the equipment on the top cover 10. At the same time, the cover plate 20 protects the equipment from damage by external substances, rainwater, and dust pollution, improving waterproof and dustproof performance and reducing air resistance during locomotive operation.

[0041] By covering the equipment with the cover plate 20, a relatively flat structure is formed on the top of the locomotive frame, reducing air resistance during locomotive movement and improving the overall appearance of the locomotive.

[0042] It should be noted that the cover plate 20 can be of different types depending on the type of equipment. In some embodiments, if the equipment does not require ventilation, the cover plate 20 can be set as a closed structure. In some embodiments, if the equipment requires ventilation, such as air conditioning, the cover plate 20 can be set as a structure with ventilation holes. Alternatively, the cover plate 20 can be set as a louver structure. In this case, in order to minimize rainwater and dust pollution, a flow guiding structure should be designed at the corresponding position of the ventilation hole to guide rainwater. The flow guiding structure is located above the ventilation hole to achieve a dustproof function.

[0043] In the embodiments of this application, the top cover 10 is used to block rainwater, and the rainwater can flow along the surface of the top cover 10 to the first drainage channel 31, and then the rainwater is discharged by the first drainage channel 31.

[0044] In some embodiments, the cover plate 20 may be attached to the device by adhesive bonding, or the cover plate 20 may be attached to the device by bolting.

[0045] In order to facilitate the smooth drainage of water, the cover plate 20 should adopt an arched design, that is, the middle of the cover plate 20 is higher and the surrounding area is lower, so as to guide rainwater to the first drainage channel 31. In addition, the cover plate 20 can prevent debris such as dead branches and leaves from entering the settling platform 11.

[0046] In some embodiments, the cover plate 20 can be designed as an integral part of the top of the equipment and cover the entire platform 11. In this case, the platform 11 and the cover plate 20 form an independent and enclosed compartment that can be used to install multiple devices.

[0047] It should be noted that the first drainage ditch 31 should have sufficient depth. When the locomotive is on a slope, the depth of the first drainage ditch 31 should be greater than the horizontal height difference between the rear wall position and the front wall position so that the rainwater of the platform 11 can be discharged smoothly.

[0048] Figure 3 A front view of the locomotive frame provided in an embodiment of this application is shown. Figure 4 It shows Figure 3 A magnified view of a portion of point A in the middle. Figure 5 A side view of the locomotive frame provided in an embodiment of this application is shown. (In conjunction with...) Figures 3 to 5 As shown, the locomotive frame also includes a second drainage structure 40, which includes a second drainage trough 41 and a first drainage pipe 42. The second drainage trough 41 is disposed within the platform 11 and communicates with the first drainage pipe 42 to drain water from the platform 11. With the above design, the second drainage trough 41 can guide water from the platform 11 to the first drainage pipe 42, and then the first drainage pipe 42 can drain the water.

[0049] The specific location of the first drainage pipe 42 can be determined according to actual needs.

[0050] Combination Figure 2 and Figure 3 As shown, the locomotive frame includes an annular retaining wall 51, which surrounds the outer perimeter of the top cover 10. The outer edge of the top cover 10 is connected to the upper edge of the annular retaining wall 51, together forming the cab 50. The first drain pipe 42 is disposed on the annular retaining wall 51. By disposing of the first drain pipe 42 on the annular retaining wall 51, the existing structure can be used to support the first drain pipe 42, avoiding the need for additional support structures.

[0051] In some embodiments, depending on the locomotive's direction of travel, the annular retaining wall 51 includes a front wall 512, a rear wall 513, and two side walls 511 located between the front wall 512 and the rear wall 513. The front wall 512, the rear wall 513, and the two side walls 511 are respectively located around the top cover 10. The first drain pipe 42 can be installed within the interlayer of the rear wall 513. The first drain pipe 42 has a vertically downward straight structure with five bends for easy unblocking.

[0052] Combination Figure 4 As shown, the second drainage structure 40 also includes an adapter box 43, which is embedded in the annular retaining wall 51. The second drainage channel 41 is connected to the adapter box 43, and the adapter box 43 is connected to the first drainage pipe 42. The adapter box 43 facilitates the connection between the second drainage channel 41 and the first drainage pipe 42, simplifying the installation structure and process.

[0053] The adapter box 43 is embedded in the rear wall 513 of the driver's cab. The side of the adapter box 43 facing the platform 11 is flush with the rear wall 513. The bottom of the adapter box 43 is not higher than the bottom wall of the first drainage trough 31 to avoid water accumulation in the first drainage trough 31.

[0054] Figure 6 A schematic diagram of the structure of the adapter box for a locomotive frame provided in an embodiment of this application is shown. (In conjunction with...) Figure 6 As shown, the adapter box 43 includes a first drainage chamber 431 and a second drainage chamber 432 spaced apart. The second drainage channel 41 is connected to the first drainage chamber 431. The second drainage structure 40 also includes a second drainage pipe 44, which is connected to the second drainage chamber 432. The second drainage chamber 432 is connected to the equipment. With the above design, water generated by the equipment can be discharged to the second drainage pipe 44 through the second drainage chamber 432, and then discharged using the second drainage pipe 44.

[0055] The adapter box 43 is equipped with a middle partition, which divides the inner cavity of the adapter box 43 into a first drainage chamber 431 and a second drainage chamber 432 that are isolated from each other. The second drainage chamber 432 and the second drainage pipe 44 can form a closed drainage path, thereby preventing blockage by foreign objects. Even if the first drainage trough 31 or the first drainage pipe 42 is blocked, the water inside the equipment can still be drained through the second drainage pipe 44.

[0056] Of course, the second drain pipe 44 can also serve as a channel for discharging liquids from certain devices, such as air conditioning condensate.

[0057] In some embodiments, the first drain pipe 42 and the second drain pipe 44 are arranged in parallel and are both disposed in the interlayer of the rear wall 513. Depending on the drainage requirements of the equipment, one or more second drain pipes 44 may be provided. When multiple second drain pipes 44 are provided, the multiple second drain pipes 44 are spaced apart within the rear wall 513.

[0058] The side of the adapter box 43 facing the recessed platform 11 is flush with the rear wall 513. The adapter box 43 is provided with a square hole and a round hole. The first drainage chamber 431 is connected to the first drainage channel 31 through the square hole, and the second drainage chamber 432 is connected to the second drainage channel 41 through the round hole.

[0059] Combination Figure 1 and Figure 2 As shown, the locomotive frame also includes a machinery compartment 60, which is located on one side of the cab 50 and is attached to the annular retaining wall 51. The top surface of the machinery compartment 60 is not higher than the bottom wall of the first drainage trough 31. By adopting the above design, and ensuring that the top surface of the machinery compartment 60 is not higher than the bottom wall of the first drainage trough 31, the machinery compartment 60 will not affect the drainage of the first drainage trough 31, allowing the first drainage trough 31 to drain water smoothly.

[0060] Figure 7 A partial structural schematic diagram of the railing of a locomotive frame provided in an embodiment of this application is shown. (In conjunction with...) Figure 1 and Figure 7 As shown, the locomotive frame also includes a side panel 70, which surrounds the platform 11. The lower edge of the side panel 70 is connected to the top cover 10, and a cover plate 20 covers the outer perimeter of the side panel 70. A portion of the annular retaining wall 51 protrudes from the top cover 10, and a first drainage channel 31 is disposed between the side panel 70 and the annular retaining wall 51. With the above design, the side panel 70 and the cover plate 20, in cooperation, can seal the platform 11, preventing foreign objects or water from entering the platform 11.

[0061] In some embodiments, when the equipment inside the sinking platform 11 does not need to exchange gases with the outside, a sealing strip can be provided between the enclosure 70 and the cover plate 20 to seal the equipment and further improve the sealing performance, preventing rainwater from entering the sinking platform 11.

[0062] Among them, at the position of the enclosure 70 near the front wall 512, the enclosure 70 is set as an L-shaped structure. The L-shaped structure fits into the side wall of the front wall 512 and forms an L-shaped drainage channel 71. The two ends of the L-shaped drainage channel 71 are connected to the first drainage channel 31. Water flows through the two ends of the L-shaped drainage channel 71 to the first drainage channel 31 and then discharges the water.

[0063] For some large equipment, which requires a large installation space, the sides of the enclosure 70 can also be designed to be close to the two side walls 511. That is to say, the sides of the enclosure 70 also adopt an L-shaped structure design to form an L-shaped drainage channel 71. Furthermore, the L-shaped drainage channels 71 are interconnected, so that water can flow between them.

[0064] Figure 8 A partial structural schematic diagram of the platform for a locomotive frame provided in an embodiment of this application is shown. (In conjunction with...) Figure 4 and Figure 8 As shown, the top cover 10 includes a connecting plate 12, a bottom plate 13, and a support frame 14. Connecting plates 12 are provided on both sides of the bottom plate 13, with the bottom plate 13 recessed within the connecting plates 12. The outer edge of the connecting plates 12 and the bottom plate 13 are respectively connected to the inner wall of the annular retaining wall 51. The support frame 14 is disposed on the bottom plate 13 and connected to the annular retaining wall 51. Using the above-described top cover 10, a recessed platform 11 is formed by the recessed bottom plate 13, and the support frame 14 provides support for the bottom plate 13, making the structure of the recessed platform 11 more stable and conducive to supporting heavier equipment. The connection between the connecting plates 12 and the annular retaining wall 51 further enhances the stability of the recessed platform 11 structure.

[0065] In some embodiments, the support frame 14 is designed as a crisscrossing frame structure, comprising staggered longitudinal beams and transverse beams. The front of the support frame 14 is connected to the front wall 512, the rear of the support frame 14 is connected to the rear wall 513, and both sides of the support frame 14 are connected to the side walls 511. The number and position of the longitudinal and transverse beams are adjusted according to the installation point and weight of the equipment, ensuring sufficient strength to withstand the weight of large equipment.

[0066] In some embodiments, there are two second drainage channels 41 and two first drainage pipes 42. The two second drainage channels 41 are located on both sides of the recessed platform 11, and the two second drainage channels 41 and the two first drainage pipes 42 are connected in a one-to-one correspondence. With the above design, the drainage capacity of the second drainage channels 41 can be improved, so that the water accumulated in the recessed platform 11 can be drained quickly.

[0067] In some embodiments, the base plate 13 is designed as a convex-shaped structure with a raised center and recessed sides, so that the second drainage channel 41 is formed on both sides of the recessed platform 11, and the raised center structure allows accumulated water to flow quickly to the second drainage channel 41, thereby improving drainage capacity.

[0068] Combination Figure 1 As shown, the top cover 10 is also provided with a mounting base 15, which is located inside the recessed platform 11. The top wall of the mounting base 15 is higher than the bottom wall of the recessed platform 11. The mounting base 15 can support the equipment, allowing the equipment to be separated from the base plate 13, preventing the equipment from being soaked by water accumulation in the recessed platform 11, thereby improving the safety of the equipment.

[0069] In some embodiments, the mounting base 15 may be a protrusion provided on the base plate 13, which supports the device and raises the device away from the base plate 13.

[0070] The locomotive frame provided in this application embodiment enables the equipment to be installed under the roof of the driver's cab without protruding from the vehicle surface. The appearance is coordinated and unified, reducing air resistance and increasing the space for locomotive equipment layout. The platform frame is connected to the main structure of the driver's cab and has excellent load-bearing capacity. The platform can be used for the installation of large equipment or as an equipment compartment to install multiple pieces of equipment. The triple drainage structure provides excellent waterproof and drainage performance.

[0071] Another embodiment of this application provides a locomotive, which includes the locomotive frame described above. Using the locomotive described above, a recessed platform 11 is provided in the top cover 10 of the locomotive frame, and a cover plate 20 is disposed at the platform 11, so that the platform 11 and the cover plate 20 together form a cavity for placing equipment. This allows the equipment to be placed within the cavity, and the platform 11 reduces the height of the equipment on the top cover 10. Simultaneously, the cover plate 20 protects the equipment from damage by external substances, rainwater, and dust contamination, improving waterproof and dustproof performance and reducing air resistance during locomotive operation.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
