Description

Technical Field

[0001] The utility model belongs to the technical field of rail locomotive parts and relates to a grille component, in particular to a grille component used for a rail locomotive roof. Background Art

[0002] A locomotive is a type of traction equipment used in rail transport. Its power is generated by a traction motor that drives the wheels, which in turn are driven by friction between the wheels and the rail surface. The locomotive roof is a crucial component of the locomotive, and its structural design is crucial to the locomotive's sealing, heat dissipation, and other performance characteristics.

[0003] Chinese utility model patent application number 201220048018.5 discloses a locomotive roof and locomotive. The locomotive roof comprises a frame, an outer cover, and an inspection window. The outer cover is fixed to the frame, and a window is formed in the outer cover, wherein the inspection window is located in the window. By providing the window in the outer cover and the inspection window in the window, operators can conveniently perform installation and maintenance on the locomotive through the inspection window. Furthermore, the locomotive roof is fixed to the locomotive body via the frame, allowing for easy connection to the body and facilitating overall assembly of the locomotive. This locomotive roof structure lacks a heat dissipation structure, which can easily lead to problems such as excessively high cabin temperatures, environmental monitoring system alarms, and sensor failures. Adding an air convection grille structure to the cabin roof can effectively reduce the problem of high cabin temperatures during locomotive operation, keeping the cabin ambient temperature below the alarm threshold of 52°C. Conventional air convection grilles, due to their simple structure and lack of a diversion mechanism, can easily allow rainwater to enter the cabin. Summary of the Invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 2 to 7The grid assembly 5 for the roof of a railway locomotive (referred to as the grid assembly 5 for short) is fixed on the roof of a railway locomotive 1 (the fixing method can be conventional, such as welding, etc.; the same applies below). Figure 1 As shown, the locomotive roof 1 generally includes an upper roof panel 11, two side slanted panels 12 formed on either side of the upper roof panel 11 and extending outwardly, and connecting panels 13 connecting the upper roof panel 11 and the corresponding side slanted panels 12 (the number of connecting panels 13 is the same as the number of side slanted panels 12, and the upper roof panel 11, side slanted panels 12, and connecting panels 13 are generally integral). Grille assemblies 5 are correspondingly fixed to the side slanted panels 12. A grille assembly 5 can be fixed to one side slanted panel 12, or more preferably, to both side slanted panels 12. The number of grille assemblies 5 fixed to each side slanted panel 12 can be determined based on actual needs and can be one, two, or more. The locomotive roof 1 can also be provided with at least one rectangular rain shield 3, at least one circular rain shield 4, and multiple sets of lifting rings 2 (typically three or more) on the upper roof panel 11, depending on actual needs. Each lifting ring set 2 includes a lifting ring seat 21 and a lifting ring 22 mounted on the lifting ring seat 21.

[0029] The grille assembly 5 comprises a matching outer baffle mechanism 51 , an inner baffle mechanism 52 , a grille plate group 53 and a liquid guide mechanism 54 .

[0030] Among them, the outer baffle mechanism 51 is as follows Figure 3 As shown, the outer baffle body 511 includes a first vent 512 provided on the outer baffle body 511, and a liquid guide port 513 provided on the outer baffle body 511 and located below the first vent 512. The outer baffle body 511 is a flat plate; the first vent 512 occupies a relatively large area, with its area typically being ≥50% of the area (one surface area) of the outer baffle body 511, preferably 60-90%; the liquid guide port 513 is an elongated strip, generally having the same length as the first vent 512, but a much smaller width.

[0031] The inner baffle mechanism 52 at least includes an inner baffle frame mounted on the surface of the outer baffle body 511 (when the grille assembly 5 is fixed to the railway locomotive roof 1, this surface faces the interior of the railway locomotive roof 1; therefore, this surface is defined as the inner surface) and forms a housing space with the outer baffle body 511. The inner baffle frame is provided with a second ventilation opening that matches the first ventilation opening 512. It can be seen that the inner baffle mechanism 52 as a whole is not a flat plate-shaped structure, but rather a three-dimensional structure. In this embodiment, the inner baffle frame includes an inner baffle 521 arranged on one side of the outer baffle body 511 (the inner surface mentioned above can be defined as the inner side) and parallel thereto, and inner baffle connecting plates 522 formed at both ends of the inner baffle 521 and connecting the inner baffle 521 and the outer baffle body 511 (the inner baffle connecting plates 522 have two pieces, which are integrally connected to the inner baffle 521 and extend to connect to the outer baffle body 511; the connection with the outer baffle body 511 here is usually a fixed connection , which can be achieved using conventional welding (the same applies below), and an inner guard upper connecting plate 523, which connects between the inner baffle 521 and the outer baffle body 511 and connects the two inner guard connecting plates 522 (the inner guard upper connecting plate 523 is typically integral with the inner baffle 521 and the two inner guard connecting plates 522 and also extends to connect to the outer baffle body 511). Thus, the outer baffle body 511, inner baffle 521, inner guard connecting plates 522, and inner guard upper connecting plate 523 define the aforementioned accommodation space. The inner baffle 521 is provided with a second vent; similarly, this second vent occupies a relatively large area, with its area typically being ≥50% of the area (one surface area) of the inner baffle 521, preferably 60-90%.

[0032] The grille plate group 53 is the core component of the grille assembly 5, which is installed in the accommodating space and cooperates with the first vent 512 and the second vent; Figure 3 and Figure 4 In the embodiment, the grille assembly 53 is arranged vertically. The grille assembly 53 includes a plurality of first guide grilles 532 installed within the inner baffle frame and spaced apart, and a plurality of second guide grilles 531 installed on the surface of the outer baffle body 511 and facing and staggered with the first guide grilles 532. Thus, each first guide grille 532 and each second guide grille 531 are also arranged vertically. In this embodiment, the first guide grilles 532 are typically fixed (usually using conventional welding, the same applies hereinafter) to the surface of the inner baffle 521, while the second guide grilles 531 are fixed to the surface of the outer baffle body 511, such that the first guide grilles 532 and the second guide grilles 531 are arranged facing each other. It should be noted that each first guide grille 532 typically has a portion that blocks the second vent, and each second guide grille 531 typically has a portion that blocks the first vent 512, to ensure effective air diversion.

[0033] In this embodiment, the first guide grid plate 532 and the second guide grid plate 531 have the same structure. Figure 8 As shown, the first guide grid plate 532 and the second guide grid plate 531 independently include a connecting portion 5300 (the connecting portion 5300 is used to be fixedly connected to the inner baffle 521 or the inner baffle 521) and two guide portions 5301 formed on the side of the connecting portion 5300 and extending outwardly (that is, the two guide portions 5301 and the connecting portion 5300 are usually integrated), and the angle formed between the guide portion 5301 and the connecting portion 5300 is an obtuse angle. In addition, as shown in FIG. Figure 6 As shown, the projections of the adjacent first guide grid plate 532 and the second guide grid plate 531 on the horizontal plane are partially overlapped, which not only improves the effect of isolating rainwater, but also helps to improve the heat dissipation effect (such as Figure 9 The grille plate assembly 53 further includes guide side plates 533 (also arranged vertically) installed in the inner frame and located on both sides of the plurality of first guide grille plates 532. These two guide side plates 533 are located on both sides of the second vent, which helps to reduce the occupied area and ensure the diversion effect at the edge.

[0034] The liquid guide mechanism 54 extends from one side (ie, the inner side) of the inner baffle mechanism 52 through the liquid guide port 513 to protrude from or be flush with the outer surface of the outer baffle body 511 , and is used to block the accumulated external rainwater and guide it to the outside. Specifically, the liquid guide mechanism 54 includes a mounting plate 541 fixed to the outer surface of the inner baffle mechanism 52, a first liquid guide plate 542 formed on the upper side of the mounting plate 541 and extending obliquely upward, and a second liquid guide plate 543 formed on the lower side of the mounting plate 541 and extending obliquely downward (the mounting plate 541, the first liquid guide plate 542, and the second liquid guide plate 543 are typically integrated). The second liquid guide plate 543 extends to or through the liquid guide opening 513. In this case, the first liquid guide plate 542 and the second liquid guide plate 543 are located on either side of the plane of the mounting plate 541, with the first liquid guide plate 542 extending obliquely away from the inner baffle 521, and the second liquid guide plate 543 extending obliquely toward the outer baffle body 511. The liquid guide mechanism 54 also includes a plurality of waist-shaped holes 540 formed on the mounting plate 541 and arranged at equal intervals.

[0035] The above-mentioned grille assembly 5 adopts a maze-shaped grille plate group 53, which, on the one hand, isolates rainwater from entering the engine compartment, and on the other hand, connects the engine compartment with the external environment, reduces the temperature in the compartment, and acts as a respirator; it can also block external rainwater and divert it to the outside; in addition, the outer baffle mechanism 51, the inner baffle mechanism 52, the grille plate group 53 and the liquid guide mechanism 54 can be easily positioned and welded together to form an assembly, which can reduce the difficulty of welding and reduce manufacturing costs; it is also easy to weld on the roof cover of a rail locomotive, which is convenient and quick.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
