DETAILED DESCRIPTION

[0034] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] As one of the main types of railway transportation vehicles, railway open wagons are mainly used to transport bulk goods such as coal, ore, and steel coils. With the supply-side structural reform of railway transportation, my country's railway wagons continue to carry out lightweight design to reduce vehicle weight and increase vehicle load; on the other hand, by expanding the types of goods transported by railway wagons, the utilization rate of vehicles is improved, thereby effectively reducing the energy consumption and carbon emission intensity of railway freight transportation and reducing the logistics costs of the whole society.

[0039] The larger the volume of a vehicle, the more goods it can transport, which improves economic efficiency and reduces vehicle transportation losses. However, in related technologies, since railway vehicles are limited by the limits of railway locomotives and vehicles, the height and width of the vehicles cannot exceed the specified area. At the same time, the height and width of railway open cars are also limited by existing ground loading and unloading facilities such as dumpers, loaders, and hopper bins, which makes it difficult to increase the volume of the vehicle.

[0040] In order to improve the above technical problems to a certain extent, the embodiments of the present application provide an open car carriage and a railway open car, which can expand the volume of the accommodating space in the width direction, so that the accommodating space can transport more goods, improve economic efficiency, and reduce vehicle transportation losses.

[0041] The following describes the embodiments of the present application in conjunction with the accompanying drawings:

[0042] See also Figure 1 The embodiment of the present application provides an open wagon carriage 10, which is applied to a railway open wagon 1. The open wagon carriage 10 provided in the embodiment of the present application can expand the volume of the accommodation space 11 in the width direction, so that the accommodation space 11 can transport more goods, improve economic benefits, and reduce vehicle transportation losses.

[0043] See also Figure 1-Figure 3 In the embodiment of the present application, the open car compartment 10 includes a base frame 100, two side walls 200 and two end walls 300. The two side walls 200 are relatively arranged along the width direction of the base frame 100, and the two end walls 300 are relatively arranged along the length direction of the base frame 100. The base frame 100, the two side walls 200 and the two end walls 300 together enclose a receiving space 11 with an open top.

[0044] Among them, the side wall 200 includes a side wall panel 210 and a plurality of side columns 220. The plurality of side columns 220 are spaced apart along the length direction of the base frame 100 on the side of the side wall panel 210 facing the accommodating space 11, and along the direction from the base frame 100 to the opening, the thickness of the side columns 220 in the width direction changes from wide to narrow.

[0045] The open car compartment 10 is roughly a rectangular parallelepiped. For the convenience of description, the height direction Z, length direction X and width direction Y are defined respectively. Among them, when the open car compartment 1010 is in use, the vertical direction is the height direction Z, the projection of the compartment in the vertical direction is a rectangle, the direction of the long side is the length direction X, and the direction of the wide side is the width direction Y.

[0046] Similarly, for the convenience of description, six directions are defined, namely, up, down, left, right, front, and back. In the height direction Z, the direction close to the opening is up, and the direction far from the opening is down. The two directions in the length direction X are front and back, respectively. The travel direction of the railway open car 1 is from back to front. The two directions in the width direction Y are left and right, respectively.

[0047] Furthermore, the side close to the accommodating space 11 is the inner side, and the side away from the accommodating space 11 is the outer side. The plurality of side pillars 220 are disposed on the side of the side wall plate 210 facing the accommodating space 11 , that is, the plurality of side pillars 220 are disposed on the inner side of the side wall plate 210 .

[0048] The storage space 11 is used to load goods, and the width of the open car compartment 10 is limited. In the related art, the side pillars 220 are arranged on the outside of the side wall plate 210, that is, the side pillars 220 are arranged outside the storage space 11, and the side pillars 220 will occupy a certain space in the width direction, so the width dimension of the storage space 11 needs to be reduced to leave space for the arrangement of the side pillars 220. In the embodiment of the present application, since the side pillars 220 are arranged on the inside of the side wall plate 210, that is, the side pillars 220 are arranged in the storage space 11, the side pillars 220 will not occupy the space outside the storage space 11 in the width direction, so that the volume of the storage space 11 can be expanded without changing the overall width dimension of the open car compartment 10, so that the storage space 11 can transport more goods, improve economic efficiency, and reduce vehicle transportation loss tons.

[0049] Along the direction from the bottom frame 100 to the opening, the thickness of the side column 220 in the width direction changes from wide to narrow, that is, the thickness of the side column 220 in the width direction changes from wide to narrow from bottom to top. It should be noted that the thickness of the side column 220 in the width direction changes from wide to narrow, that is, the thickness of the side column 220 in the width direction may change from wide to narrow gradually, or may change from wide to narrow in sections, that is, the thickness of a certain section of the side column 220 may be wider than the thickness of a certain section below it, but the overall change trend is from wide to narrow from bottom to top.

[0050] Specifically, since the thickness of the side column 220 in the width direction tends to change from wide to narrow along the direction from the base frame 100 to the opening, and the side wall panel 210 is perpendicular to the base frame 100, and the side of the side column 220 close to the side wall panel 210 is roughly in a vertical direction, the change in the thickness of the side column 220 in the width direction can be achieved by setting a slope on the side of the side column 220 away from the side wall panel 210, that is, the side column 220 can be roughly in a right-angled trapezoid, and the right-angled side is in contact with the side wall panel 210.

[0051] It is understandable that when the storage space 11 is loaded with goods, the bottom pressure of the storage space 11 is the largest, and the lateral pressure on the lower part of the side wall plate 210 is also relatively large, while the lateral pressure on the upper part of the side wall plate 210 is relatively small, so the lower part of the side column 220 is thicker, so that the bearing capacity is stronger, and the upper part can be designed to be thinner, so that the manufacturing material of the side column 220 can be reduced, saving costs. In addition, since railway vehicles have restrictions on the total weight of the vehicle after loading, after the manufacturing material of the side column 220 is reduced, the dead weight of the open car carriage 10 is also reduced, so that the load of the railway open car 1 is increased, and then the volume of the storage space 11 can be expanded to transport more goods.

[0052] See also Figure 3 and Figure 4 In some embodiments, the upper portion of the side wall plate 210 has an inclined portion 211 inclined toward the accommodating space 11 , and the upper portion of the side column 220 is provided with an inclined surface 221 , which is in contact with the inclined portion 211 .

[0053] Draw a center line extending along the length direction on the side wall plate 210, the portion above the center line is the upper portion of the side wall plate 210, and the portion below the center line is the lower portion of the side wall plate 210. The entire upper portion may be inclined toward the accommodation space 11, or a portion of the upper portion may be inclined toward the accommodation space 11, and there is no limitation on this.

[0054] The inclined portion 211 is inclined toward the accommodation space 11. In other words, the inclined portion 211 is bent toward the accommodation space 11, thereby increasing the rigidity of the side wall plate 210. Since the side column 220 is connected to the side wall plate 210, the side column 220 also needs to be provided with an inclined surface 221 to match the inclined portion 211, thereby making the connection between the side column 220 and the side wall plate 210 stable.

[0055] See also Figure 3 and Figure 4 In some embodiments, the side wall 200 further includes an upper beam 230 and a reinforcement beam 240. The upper beam 230 is disposed at the top of the inclined portion 211, and the upper beam 230 and the inclined portion 211 are disposed at an angle. The reinforcement beam 240 is disposed between the upper beam 230 and the inclined portion 211, and connects the upper beam 230 and the side wall panel 210.

[0056] Since the inclined portion 211 is inclined toward the accommodating space 11 and the upper beam 230 is arranged horizontally, an angle is formed between the upper beam 230 and the inclined portion 211. The reinforcing beam 240 is arranged outside the predicted wall panel, and is used to connect the upper beam 230 and the side wall panel 210, so that the upper beam 230 and the side wall panel 210 form a whole, so as to improve the structural strength of the side wall panel 210. The reinforcing beam 240 is arranged between the upper beam 230 and the inclined portion 211, that is, the reinforcing beam 240 is arranged within the angle formed by the upper beam 230 and the inclined portion 211, so as to reduce the additional space occupied by the reinforcing beam 240 outside the side wall panel 210 in the width direction, and further ensure the volume of the accommodating space 11.

[0057] Specifically, the side of the reinforcement beam 240 away from the accommodating space 11 is flush with the side of the side wall panel 210 away from the accommodating space 11, that is, the reinforcement beam 240 does not occupy additional space in the width direction, thereby ensuring the volume of the accommodating space 11 and improving the aesthetics of the open car compartment 10.

[0058] See also Figure 3 and Figure 4 In some embodiments, the side wall plate 210 further has a bending portion 212 , which is bent toward the accommodating space 11 , and the side column 220 has a bending opening 222 , in which the bending portion 212 is fitted.

[0059] The bending portion 212 is bent into the accommodating space 11, so as to further improve the rigidity of the side wall panel 210. Since the upper portion of the side wall panel 210 is provided with the inclined portion 211 to improve the rigidity, the bending portion 212 can be provided at the lower portion of the side wall panel 210. The bending portion 212 can be regarded as the outer side of the side wall panel 210 being recessed inward, so that the inner side of the side wall panel 210 has a bulge. Since the side column 220 is connected to the inner side of the side wall panel 210, a bending opening 222 is correspondingly provided on the side column 220 to adapt to the bending portion 212, so that the bending portion 212 can fit into the bending opening 222, so that the connection between the side column 220 and the side wall panel 210 is stable.

[0060] It needs to be explained that since the bending portion 212 is arranged at the lower part of the side wall panel 210, the bending mouth 222 is also arranged at the lower part of the side column 220, that is, the thickness of the area where the bending mouth 222 is arranged on the side column 220 will be smaller than the thickness of the area above the bending mouth 222, but since the size of the bending mouth 222 is small, the overall change trend of the thickness of the side column 220 in the width direction is still from wide to narrow.

[0061] It is understandable that the intersection of the bent portions 212 forms a corner. Since the corner is sharp, it is easy to damage the goods in the accommodating space 11. Therefore, the intersection of the bent portions 212 is transitioned through a plane.

[0062] See also Figure 3 and Figure 4 In some embodiments, a first transition plate 240 is disposed at the lower portion of the side wall plate 210 . The first transition plate 240 is arc-shaped and is connected to the base frame 100 .

[0063] Since the lower part of the side wall plate 210 is connected to the bottom frame 100 through the first transition plate 240, and the first transition plate 240 is arc-shaped, when the goods in the storage space 11 contact the first transition plate 240, they will slide down to the bottom frame 100 under the effect of the arc, thereby improving the accumulation of goods at the intersection of the side wall plate 210 and the bottom frame 100. Of course, in order not to affect the volume of the storage space 11, the opening of the first transition plate 240 is set toward the storage space 11.

[0064] Similarly, the lower part of the side column 220 has a second transition plate 260, the second transition plate 260 is arc-shaped, and the second transition plate 260 is connected to the bottom frame 100. Since the lower part of the side column 220 is connected to the bottom frame 100 through the second transition plate 260, and the second transition plate 260 is arc-shaped, when the goods in the storage space 11 contact the second transition plate 260, under the effect of the arc, they will slide to the bottom frame 100, thereby improving the accumulation of goods at the intersection of the side column 220 and the bottom frame 100. Of course, in order not to affect the volume of the storage space 11, the opening of the second transition plate 260 is set toward the storage space 11.

[0065] See also Figure 3 and Figure 4 In some embodiments, the storage space 11 is used to load containers, and the containers can be installed into the storage space 11 through the opening. A guide slope 223 is provided on the side of the side column 220 away from the side wall plate 210 to provide guidance for the installation of the container.

[0066] As described above, the side column 220 can be roughly in the shape of a right-angled trapezoid, with the right-angled side being in contact with the side wall panel 210, and the inclined surface 221 can be configured as a guide slope 223. When loading a container, in order to accurately install the container into the accommodating space 11 and avoid a large number of collisions between the container and the open car compartment 10, the operator needs to climb up to observe and visually locate to assist the loading driver in loading. In the embodiment of the present application, since the side column 220 is arranged in the accommodating cavity, the structure of the side column 220 can be utilized to set a guide slope 223 on the side of the side column 220 away from the side wall panel 210, so that when loading the container, the guide slope 223 can provide guidance for the installation of the container, so as to reduce the shaking of the container during the loading process, which may cause collision with the side wall panel 210 and damage the side wall panel 210.

[0067] See also Figure 1 In some embodiments, the side wall 200 further includes two support assemblies 270, which are respectively disposed at the upper and lower portions of the side wall 200. The support assemblies 270 protrude from the side of the side wall panel 210 away from the accommodating space 11, and are used to contact the backrest plate of the tipping machine.

[0068] When the railway open car 1 is unloaded by using a tipping machine, the tipping machine needs to clamp the entire open car compartment 10, and then flip the entire open car compartment 10 165 degrees for unloading. The tipping machine clamps the open car, that is, a large car-resting plate is used to gradually close the outer side of the railway open car 1 to the outer plane of the side wall plate 210 to implement the clamping, that is, the car-resting plate needs to contact the outer side of the side wall plate 210. Since the side wall 200 also includes two support assemblies 270, the two support assemblies 270 are protrudingly arranged on the side of the side wall plate 210 away from the accommodating space 11, that is, the support assemblies 270 are protrudingly arranged on the outer side of the side wall plate 210, so when the tipping machine clamps the open car compartment 10, the support assemblies 270 are in contact with the car-resting plate. Since the two support assemblies 270 are respectively arranged at the upper and lower parts of the side wall 200, the force on the outer side of the side wall plate 210 can be balanced, thereby effectively improving the force on the vehicle when the tipping machine is operating.

[0069] Specifically, the support assembly 270 includes a plurality of support plates 271, and the plurality of support plates 271 are arranged at intervals along the length direction of the bottom frame 100. The plurality of support plates 271 can be arranged at equal intervals, thereby further improving the force uniformity of the outer side of the side wall plate 210.

[0070] See also Figure 5 In some embodiments, the storage space 11 is used to install a container, and the container includes a side surface and an end surface set at an angle. The carriage also includes a positioning assembly 400 installed in the storage space 11, and the positioning assembly 400 includes a first positioning member 410 and a second positioning member 420. The first positioning member 410 has a first positioning surface, and the second positioning member 420 has a second positioning surface; wherein, when the container is installed in the storage space 11, the first positioning surface contacts the side surface, and the second positioning surface contacts the end surface, so that the container is fixedly set in the storage space 11.

[0071] In the related art, after the container is loaded into an open truck, it is necessary to manually fill the gap between the container and the truck body with fillers such as wood or sandbags to prevent the container from moving inside the truck body during transportation, resulting in high labor costs, low efficiency, and large waste of auxiliary materials when loading containers on open trucks.

[0072] The container is also roughly rectangular, and the side faces are arranged along the length direction, and the end faces are arranged along the width direction. When the container is installed in the storage space 11, the bottom wall of the storage space 11 supports the container, thereby limiting the container in the height direction. Since the first positioning surface contacts the side face and the second positioning surface contacts the end face to position the container, that is, the first positioning surface limits the container in the width direction, and the second positioning surface limits the container in the length direction, so that under the common limitation of the first positioning surface and the second positioning surface, the container can be fixed in the storage space 11.

[0073] That is, the open car body 10 provided in the embodiment of the present application is provided with a positioning assembly 400 in the body to position the container, thereby eliminating the need to manually fill the gap between the container and the body with fillers such as wood blocks or sandbags, thereby greatly reducing labor costs, improving work efficiency, and saving filling materials.

[0074] Based on the same inventive concept, the present embodiment also provides a railway open wagon 1, including the above-mentioned open wagon compartment 10. The beneficial effects of the railway open wagon 1 provided by the present embodiment are the same as those of the open wagon compartment 10, which will not be described in detail.

[0075] See also Figure 6 and Figure 7Specifically, the chassis 100 mainly includes a middle beam 110, a bolster 120, a cross beam 130, a central cross beam 140, a water leakage device 150, a reinforcement beam 160 and a floor 170. Among them, the middle beam 110, the bolster 120, the cross beam 130, the central cross beam 140, the reinforcement beam 160, the floor 170 and other components are combined by a fixed connection method to provide the main bearing function for the vehicle cargo transportation, and a number of water leakage devices 150 are arranged on both sides of the floor 170 to provide drainage function for the vehicle water accumulation. Among them, the beam 110 is arranged along the width direction, in the shape of a small fish belly, which can effectively improve the vertical stiffness of the vehicle; the water leakage device 150 mainly includes a cover plate 151 and a diversion pipe 152. The cover plate 151 can prevent the leakage of bulk cargo, and the diversion pipe 152 can prevent the water from spreading to the lower plane of the floor 170 to aggravate the corrosion of the floor 170.

[0076] See also Figure 8 and Fig. 9 The railway open car 1 also includes a safety climbing device 30.
