Description

Technical Field

[0001] This utility model relates to the field of vehicle equipment technology, and in particular to a funnel car end wall and a funnel car. Background Technology

[0002] Hopper car transportation has advantages such as high unloading efficiency, low overall investment, low daily operating costs, and good working conditions. Using hopper cars to transport bulk cargo such as coal is a relatively economical transportation method, which has become a consensus among foreign railway transportation companies. Especially on lines that are close to mining areas, have large transport volumes, and have fixed coal transport sections, the overall transportation benefits are even more obvious.

[0003] The hopper car has a loading hopper at the bottom of the car body between the two bogies. After the loading hopper is opened, the bulk cargo loaded inside the car falls under its own weight and flows through the loading hopper to be discharged. Since loading hoppers cannot be installed above the bogies at both ends of the vehicle, the end walls of the hopper car above them need to be designed with a certain angle to the horizontal plane. This angle should be greater than the angle of repose of the bulk cargo, so that the cargo can be discharged by gravity. The end walls of the hopper car not only need to bear the pressure load of the bulk cargo inside the car, but also need to withstand the inertial impact load generated during the operation of the vehicle due to the train starting, braking, curves, slopes, acceleration, and deceleration.

[0004] Currently, the end walls of funnel carts generally adopt a steel plate-column structure, which consists of metal components such as end wall plates, upper beams, inclined end plates, crossbars, and end columns. This structure is heavy, complex, and difficult to manufacture. Furthermore, the structural reliability of the end wall plates under impact loads is difficult to meet requirements. Increasing the number of crossbars or adding diagonal bracing structures that run through the crossbars could improve the structural reliability of the end wall plates, but this would undoubtedly further increase the weight and structural complexity.

[0005] Therefore, how to reduce weight while ensuring structural reliability is a problem that urgently needs to be solved by those in this technical field. Utility Model Content

[0044] This utility model discloses an end wall for a funnel cart to reduce weight and ensure structural reliability. This utility model also provides a funnel cart.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] like Figures 1-5 As shown, this utility model embodiment provides a funnel cart end wall, including an end wall plate 100, a support component 200, and a connecting seat 300. The end wall plate 100 includes a first structural layer 101 and a second structural layer 102 stacked together. The first structural layer 101 and the second structural layer 102 are made of composite materials. The side of the first structural layer 101 facing away from the second structural layer 102 is the inner side of the end wall plate 100, and the side of the second structural layer 102 facing away from the first structural layer 101 is the outer side of the end wall plate 100. The connecting seat 300 is connected to the end wall plate 100, and the support component 200 is connected to the outer side.

[0047] The end wall panel 100 has a first region 110 and a second region 120. A filling interlayer 103 is provided between the first structural layer 101 and the second structural layer 102 in the first region 110. The first structural layer 101 and the second structural layer 102 in the second region 120 are connected. The support component 200 and the connecting seat 300 are connected to the second region 120.

[0048] The funnel cart end wall provided in this embodiment of the invention effectively reduces the weight of the end wall plate 100 by using composite materials to make the first structural layer 101 and the second structural layer 102, thereby reducing the overall weight of the funnel cart end wall. This facilitates the lightweight design of the funnel cart using the end wall provided in this embodiment of the invention, improving transportation economic efficiency. Furthermore, the end wall plate 100 has a first region 110 and a second region 120. A filling interlayer 103 is provided between the first structural layer 101 and the second structural layer 102 in the first region 110. The first structural layer 101 and the second structural layer 102 in the second region 120 are interconnected, forming a closed box structure in the first region 110. From a structural mechanics perspective, compared with the single-layer structure end wall plate in the prior art, the structure of the first region 110 has a higher load-bearing capacity. Compared with the second region 120, the first region 110 is similar to a reinforcing beam on the end wall plate 100, avoiding the need for additional horizontal or diagonal bracing structures, thus meeting the reliability requirements of the end wall plate 100 under impact loads.

[0049] Furthermore, in the second region 120, the first structural layer 101 and the second structural layer 102 are connected, making the second region 120 a solid laminate structure. The connection between the support component 200 and the connecting seat 300 and the second region 120 ensures the reliability of the structural connection.

[0050] In this embodiment, the first structural layer 101 and the second structural layer 102 are made of carbon fiber composite material or fiber reinforced resin matrix composite material, that is, the end wall plate 100 is a sandwich structure made of carbon fiber composite material.

[0051] The first structural layer 101 and the second structural layer 102 can be constructed from 2-4 mm thick carbon fiber reinforced resin matrix composite materials using a laminated layup design. Specifically, at least one of the first structural layer 101 and the second structural layer 102 is formed by laminating multiple composite material layers using a laminated layup method. Multiple fiber layers are laid up along the thickness direction of the first structural layer 101 and the second structural layer 102 at specific angles (e.g., 0°, ±45°, 90°, etc.) and in a specific sequence, and then bonded together by resin curing to form a composite material laminate (first structural layer 101 or second structural layer 102). Combined with the thickness of the filling interlayer 103, the thickness of the first region 110 of the end wall panel 100 can range from 40 to 70 mm. The thickness of the second region 120 is the sum of the thicknesses of the first structural layer 101 and the second structural layer 102. Taking carbon fiber composites as an example, the tensile strength of carbon fiber composites can generally reach over 1000 MPa, while the existing end walls of hopper cars generally use Q450NQR1 high-strength steel (tensile strength of 550 MPa) or 6061-T6 aluminum alloy (tensile strength of 265 MPa). Therefore, using carbon fiber composites can achieve both lightweighting of the car body and increased strength reserves. Furthermore, the density of carbon fiber composites is only 1 / 4 that of steel and 2 / 3 that of aluminum alloy, thus adapting to the increasing load trends in railway freight cars, especially heavy-haul freight cars.

[0052] The filling interlayer 103 can be formed of a foam material, i.e., by filling the space between the first structural layer 101 and the second structural layer 102 in the first region 110 with rigid closed-cell foam (rigid closed-cell PMI (polymethacrylimide) foam) or other types of foam to form the filling interlayer 103. This is to withstand pressure loads (such as lateral pressure loads exerted on the end wall panel 100 by bulk cargo such as coal inside a vehicle).

[0053] The second region 120 can be located on the outer periphery of the first region 110. Since there is a filling interlayer 103 between the first structural layer 101 and the second structural layer 102 in the first region 110, and the first structural layer 101 and the second structural layer 102 in the second region 120 are interconnected, a cavity capable of accommodating the filling interlayer 103 is formed between the first structural layer 101 and the second structural layer 102 in the first region 110. Because the edge of the first structural layer 101 and the second structural layer 102 in the first region 110 is the second region 120, the connection between the first structural layer 101 and the second structural layer 102 located outside the first region 110 (second region 120) forms a closed structure (such as a closed box structure).

[0054] In some embodiments, the number of first regions 110 is at least two and arranged along the height direction of the funnel end wall, and the second region 120 includes an intermediate connecting region 121 located between two adjacent first regions 110, and the support component 200 is connected to the intermediate connecting region 121.

[0055] like Figure 2 and Figure 5 As shown, there can be two first regions 110, namely an upper interlayer region 111 and a lower interlayer region 112. An intermediate connecting region 121 is formed between the upper interlayer region 111 and the lower interlayer region 112 to facilitate connection with the support component 200. That is, the intermediate connecting region 121 is located in the middle region of the end wall plate 100 along the height direction of the funnel end wall. The intermediate connecting region 121 is connected to the support component 200 so as to form a support point in the middle part of the length direction of the end wall plate 100 (which can be the exact center position or not the exact center position, but between the two sides of the length direction of the end wall plate 100), thereby effectively improving the support effect of the end wall plate 100 and reducing the bending deformation of the end wall plate 100 along the length direction.

[0056] Furthermore, the second region 120 also includes at least one of the following:

[0057] Side connection areas 122 are located on both sides of the end wall plate 100, and a first area 110 is located between the two side connection areas 122. The side connection areas 122 of the end wall plate 100 can be connected to the side wall of the vehicle body by means of riveting or other methods to achieve the effect of fixing the two sides of the end wall plate 100.

[0058] The upper connecting area 123 is located at the upper edge of the end wall plate 100, and the connecting seat 300 is connected to the top edge of the upper connecting area 123. Since the connecting seat 300 is connected to the top edge of the upper connecting area 123, the connecting seat 300 can be higher than the end wall plate 100. When the end wall plate 100 is assembled with the vehicle body, the side beams on the vehicle body that are connected to the side walls of the vehicle body can be connected to the connecting seat 300 to achieve connection and fixation at the top of the end wall plate 100. This allows the height of the side walls of the vehicle body to be higher than the height of the end wall plate 100. That is, the side walls of the vehicle body and the end walls of the hopper car are not of equal height, and the height of the side walls of the vehicle body is higher than that of the end walls of the hopper car. This allows for adaptation to the loading height requirements of the hopper car when the height of the vehicle body is increased (the height of the side walls of the vehicle body is increased) without changing the height of the end walls of the hopper car. When the height of the upper side beam of the vehicle body (located between two side walls of the vehicle body or on the side wall of the vehicle body, etc.) is higher than that of the end wall plate 100, the end wall plate 100 can be connected to the upper side beam of the vehicle body by means of riveting or welding through the connecting seat 300 to achieve the effect of fixing the top of the end wall plate 100.

[0059] The number of connecting seats 300 can be two, and they are located at both ends of the top edge of the upper connecting area 123, that is, the two connecting seats 300 are located at the two corners above the end wall plate 100.

[0060] The lower connecting area 124, located at the lower edge of the end wall plate 100, is connected to the upper connecting area 123 via the connecting seat 300. The end wall plate 100 can be connected to the vehicle chassis via the lower connecting area 124 through riveting or other means to achieve a fixed effect on the bottom of the end wall plate 100.

[0061] The inner surface of the end wall panel 100 is flat; the portion of the first structural layer 101 located in the first region 110 protrudes beyond the portion of the first structural layer 101 located in the second region 120. Since the first region 110 has a filling interlayer 103, the thickness of the first region 110 is different from the thickness of the second region 120. In order to meet the unloading effect of bulk cargo inside the vehicle, the first structural layer 101 can be set as a concave-convex structural layer, and the second structural layer 102 can be a flat structural layer, so that the inner surface of the end wall panel 100 is flat, which facilitates the movement and unloading of bulk cargo along the inner surface of the end wall panel 100 under the action of gravity.

[0062] To reduce stress concentration, a transition region 130 is provided between the first region 110 and the second region 120. A transition filler layer 104 is located between the first structural layer 101 and the second structural layer 102 in the transition region 130, and the thickness of the transition filler layer 104 decreases along the direction closer to the second region 120. The thickness direction of the transition filler layer 104 is the same as the arrangement direction of the first structural layer 101 and the second structural layer 102. That is, the cross-section of the portion of the first structural layer 101 corresponding to the first region 110 and the transition region 130 can be a trapezoidal structure, and the transition filler layer 104 and the filler interlayer 103 can be an integral structure, so that a structural transition is formed from the first region 110 to the second region 120, avoiding stress concentration. Specifically, from the first region 110 to the second region 120, the filler interlayer 103 and the transition filler layer 104 form a sloping structure, and the first region 110 with the interlayer gradually and uniformly transitions to the second region 120, which is a solid laminate.

[0063] In this embodiment, the end wall plate 100 is an integral hot-pressed structure, where the first structural layer 101 and the second structural layer 102 located in the second region 120 are connected by hot pressing. That is, the end wall plate 100 can be formed into a composite material sandwich structure by integral molding, which improves the bending strength in all directions. Furthermore, by setting the end wall plate 100 as an integral hot-pressed structure, the number of parts of the funnel car end wall is significantly reduced, and the manufacturing processes such as welding or riveting connections during the processing of the end wall plate 100 are reduced, effectively simplifying the manufacturing process of the funnel car end wall and shortening the production cycle of the funnel car end wall.

[0064] Taking the first structural layer 101 and the second structural layer 102 as using 2-4 mm thick carbon fiber reinforced resin matrix composite prepreg, and the filling interlayer 103 as using rigid closed-cell PMI foam as an example, in the process of integrally hot-pressing the end wall panel 100, firstly, the prepreg of the second structural layer 102 is laid layer by layer on the pre-made mold surface to a specified thickness. Then, a foam layer of a specified shape is applied to the laid second structural layer 102. Next, the prepreg of the first structural layer 101 is laid on the foam layer and the second structural layer 102 to a specified thickness. Then, the completed end wall panel assembly, together with the mold, is placed in a hot autoclave or oven. The hot autoclave is heated and pressurized for a certain period of time until the resin matrix material completes the chemical curing reaction, and the composite sandwich structure end wall panel forms an integral structure. The foam layer forms the filling interlayer 103. Finally, the cured end wall panel blank undergoes demolding, grinding, and hole-opening post-processing steps, thus completing the processing and manufacturing of the end wall panel 100 as a composite sandwich structure.

[0065] In some embodiments, to ensure support effectiveness, the support assembly 200 includes an end plate 210 and an end post 220. The end plate 210 has a connecting end connected to the end wall plate 100 and a supporting end for connecting to the vehicle chassis frame. The end plate 210 can form a certain angle with the end wall plate 100. The end post 220 is connected to the end plate 210 and extends along the height direction of the end plate 210. The length direction of the end plate 210 is the arrangement direction of the connecting end and the supporting end.

[0066] The side edges of the end plate 210 can be aligned with the side edges of the end wall plate 100. That is, the two side edges of the end plate 210 are arranged in the width direction of the end plate 210, and the two side edges of the end wall plate 100 are arranged in the width direction of the end wall plate 100. Therefore, the width of the end plate 210 is the same as the width of the end wall plate 100. This arrangement increases the area of ​​the end plate 210 supporting the end wall plate 100, thereby improving support stability.

[0067] The number of end posts 220 can be multiple (such as two, three, or four), and the multiple end posts 220 are evenly arranged along the arrangement direction of each of the two side edges of the end plate 210. That is, the multiple end posts 220 are arranged along the width direction of the end plate 210.

[0068] The height of the end post 220 can be the same as the height of the end plate 210, so that the two ends of the end post 220 are aligned with the upper edge and the lower edge of the end plate 210, respectively.

[0069] To ensure support and facilitate connection, the end plate 210 is a metal profiled structure, and the end column 220 is a metal column. The end plate 210 and end column 220 can be welded to the vehicle body underframe. Specifically, the end plate is a steel plate profiled structure, and the end column is a channel-shaped cold-formed steel section.

[0070] Furthermore, the connecting seat 300 is connected to the upper edge of the end wall plate 100. This arrangement allows the connecting seat 300 to be higher than the end wall plate 100. When the end wall plate 100 is assembled with the vehicle body, the connecting seat 300 can be connected to the upper side beam of the vehicle body, which is higher than the end wall plate 100, thereby increasing the load capacity.

[0071] Furthermore, the number of connecting seats 300 is at least two and they are symmetrically arranged relative to the end wall plate 100. In this embodiment, the number of connecting seats 300 is two and they are located at two corners above the end wall plate 100.

[0072] This utility model embodiment also provides a hopper cart, including a cart body and a hopper cart end wall disposed on the cart body, wherein the hopper cart end wall is any of the hopper cart end walls described above. Since the hopper cart end walls described above have the above-mentioned technical effects, the hopper cart having the above-mentioned hopper cart end walls should also have the same technical effects, and no specific limitations are made here.

[0073] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0074] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
