[0023] 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.

[0024] Hereinafter, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] Railway transportation is characterized by its large transport capacity, high speed, and low cost, making it the mainstay of coal energy transportation.

[0026] During coal transportation in low-temperature environments, the high moisture content of the coal can cause it to freeze and stick to the truck's side panels. Currently, coal stuck to the side panels is usually removed manually, such as by knocking or scraping with a pickaxe. However, manual cleaning is labor-intensive, inefficient, and causes significant damage to the vehicle.

[0027] Based on the above-mentioned technical problems, this application discloses a truck body that integrates a circulation channel. By filling the circulation channel with hot air, the truck body is heated, thereby separating the material frozen on the truck body from the truck body.

[0028] like Figure 1 As shown, the truck body of this embodiment includes: side wall 100, end wall 200 and underframe 300.

[0029] The side wall 100 extends along a first direction, and the end wall 200 extends along a second direction. Both the side wall 100 and the end wall 200 are mounted on the base frame 300. The first and second directions are intersecting directions. Optionally, the first and second directions are perpendicular, and both are parallel to the plane of the base frame 300. Optionally, the third direction in this document is a direction perpendicular to the base frame 300.

[0030] In some embodiments, there are two side walls 100 and two end walls 200, with the two side walls 100 arranged opposite each other along a second direction and the two end walls 200 arranged opposite each other along a first direction. The side walls 100 and end walls 200 are arranged face-to-face and sequentially fixedly connected to form a closed structure. The side walls 100, end walls 200, and underframe 300 enclose a cargo space for the truck body, which is used to place the goods transported by the truck.

[0031] The connection between the side wall 100, the end wall 200 and the base frame 300 can be welded or threaded, and the connection between the side wall 100, the end wall 200 and the base frame 300 is not limited to these.

[0032] At least one of the side wall 100 and end wall 200 in this embodiment has a circulation channel (not shown in the figure). One end of the circulation channel has an inlet communicating with the circulation channel, and the other end of the circulation channel has an outlet communicating with the circulation channel.

[0033] During the de-icing or material removal process of trucks using this vehicle body, the steam source (e.g., high-temperature steam or hot air) at the unloading site can be connected to the inlet to introduce high-temperature steam or hot air into the circulation channel. The high-temperature heat will heat the vehicle body, causing the frozen coal on the inner surface of the vehicle body to thaw quickly. This method does not require manual cleaning, thereby reducing the labor intensity of manual coal cleaning operations, improving cleaning efficiency, and reducing damage to the vehicle.

[0034] In some embodiments, the outlet may be connected to a piping system at the unloading site to recover low-calorific-value steam or condensate.

[0035] In some embodiments, the circulation channels of the side wall 100 and the end wall 200 may be pipes attached to the side wall 100 and the end wall 200. The pipes attached to the side wall 100 or the end wall 200 may cause damage to the pipes by the cargo contained in the truck.

[0036] In some other embodiments, the circulation channel may also be formed by the sidewall 100 and the endwall 200 themselves, as described below. Figure 2 and Figure 3 The structure of side wall 100 is described, in conjunction with Figure 4 and Figure 5 The structure of end wall 200 is described.

[0037] like Figure 2 As shown, the side wall 100 includes: a first hollow profile 101, a first sealing plate 102, and a first pipe joint 103.

[0038] The first hollow profile 101 has a first hollow cavity. It can be understood that the first hollow profile 101 is a hollow structure, and the hollow structure of the first hollow profile 101 forms the first hollow cavity. Optionally, the first hollow cavity of the first hollow profile 101 extends along a first direction.

[0039] In some embodiments, the first hollow profile 101 is a hollow profile obtained by extrusion. Using extrusion molding to form the first hollow profile 101 can ensure its strength, reduce the number of connection points in the first hollow profile 101, and improve the processing efficiency of the first hollow profile.

[0040] The first hollow profile 101 has a hollow structure, making the ends of the first hollow profile 101 along the first direction open. Based on this, the side wall 100 of this application embodiment is provided with a first sealing plate 102 at the end of the first hollow profile 101 along the first direction. The first sealing plate 102 is used to seal the end of the first hollow profile 101, so that the first hollow profile 101 and the first sealing plates 102 at both ends form a sealed first hollow cavity, which serves as a circulation channel for the side wall 100.

[0041] The first hollow cavity of the first hollow profile 101 of the side wall 100 serves as the circulation channel of the side wall 100, that is, the hollow cavity of the vehicle body itself is used as the channel for steam source heating, which has the characteristics of integrated structure and function, reducing the cost of additional circulation channels.

[0042] The shape of the first sealing plate 102 can be set according to the shape of the first hollow cavity cross section of the first hollow profile 101. It is understood that the shape of the first sealing plate 102 is adapted to the shape of the end face of the first hollow profile 101. The adaptation in this article includes the same size and the same shape.

[0043] A first pipe joint 103 is provided on the first sealing plate 102. It is known that the first hollow profile 101 has a first sealing plate 102 at both ends along the first direction, and a first pipe joint 103 is provided on each of the first sealing plates 102. The first pipe joint 103 at one end of the first hollow profile 101 along the first direction can be connected to the steam source at the unloading site, and the first pipe joint 103 at the other end of the first hollow profile 101 along the first direction can be connected to the pipeline system at the unloading site for the purpose of recovering low-calorific-value steam or condensate.

[0044] like Figure 3 As shown, the side wall 100 is provided with a plurality of first hollow profiles 101 along a third direction, and adjacent first hollow profiles 101 are fixedly connected.

[0045] In this embodiment, the sidewall 100 is arranged with multiple first hollow profiles 101 along a third direction, which increases the area of ​​the sidewall 100. This can be understood as the sidewall 100 being composed of multiple connected first hollow profiles 101. Dividing the sidewall 100 into multiple first hollow profiles 101 divides the overall first hollow cavity into multiple smaller first hollow cavities, which is beneficial for guiding the air source using these smaller cavities. Furthermore, the smaller volume of the first hollow profile 101 results in higher strength, thus increasing the overall strength of the sidewall 100.

[0046] The dimensions of the first hollow profile 101 along the first direction, the second direction, and the third direction can be set according to different needs, and are not specifically limited here.

[0047] In some embodiments, the first hollow profiles 101 arranged adjacent to each other along a third direction can be connected by welding or by threaded connectors. The connection method of adjacent first hollow profiles 101 is not limited to the above-described connection methods.

[0048] In some embodiments, the first hollow profiles 101 arranged adjacent to each other along a third direction may be connected or isolated from each other (i.e., not connected).

[0049] If the first hollow profiles 101 arranged adjacent to each other along the third direction are connected, openings can be made on the opposite sidewalls of the adjacent first hollow profiles 101 along the third direction, and the openings of the adjacent first hollow profiles 101 are sealed and connected.

[0050] By connecting adjacent first hollow profiles 101 along a third direction, the steam source flowing within adjacent first hollow profiles 101 can flow between them. In some embodiments, the first hollow profiles 101 arranged adjacently along a third direction are connected sequentially, so that the first hollow cavities of the sidewall 100 are connected as a circulation channel. This method can reduce the number of inlets and outlets on the sidewall 100 and reduce costs.

[0051] The first hollow profiles 101 arranged adjacent to each other along a third direction are not interconnected. Steam can be injected into each first hollow profile 101, resulting in a high steam injection rate per unit time and improving the heat exchange effect of the sidewall 100. This avoids the problem of uneven temperature distribution on the sidewall 100 caused by the steam source cooling down after heat exchange during its long-path circulation along the sidewall 101. It should be noted that in the configuration where all the first hollow cavities of the first hollow profiles 101 are connected as a single circulation channel, the area covered by the circulation channel on the sidewall 100 is the same as the area covered by the circulation channel on the sidewall 100 in the configuration where the first hollow cavities of the first hollow profiles 101 are individually arranged.

[0052] like Figure 4 and Figure 5 As shown, the end wall 200 includes: a second hollow profile 201, a second sealing plate 202, a second pipe joint 203, a support plate 204, and a connecting plate 205.

[0053] The second hollow profile 201 is arranged vertically or inclined to the base frame 300, and the relationship between the second hollow profile 201 and the base frame 300 can be set according to the needs of the truck. The second hollow profile 201 being arranged vertically to the base frame 300 increases the volume of the accommodating space. The second hollow profile 201 being inclined to the base frame 300, under the action of the support plate 204, allows the end wall 200 to be arranged in a herringbone shape, which helps to improve the strength of the end wall 200.

[0054] The second hollow profile 201 has a second hollow cavity, which extends along the setting direction of the second hollow profile 201, that is, the second hollow cavity extends along the direction inclined to the base frame 300.

[0055] The second hollow profile 201 has a hollow structure, making its ends along the extension direction of the second hollow profile 201 open. Based on this, the end wall 200 of this embodiment of the application is provided with a second sealing plate 202 at the end of the second hollow profile 201. The second sealing plate 202 is used to seal the end of the second hollow profile 201, so that the second hollow profile 201 and the second sealing plates 202 at both ends form a sealed second hollow cavity, which serves as a circulation channel for the end wall 200.

[0056] The second hollow cavity of the second hollow profile 201 of the end wall 200 serves as the circulation channel of the end wall 200. That is, the hollow cavity of the vehicle body itself is used as the channel for steam source heating, which has the characteristics of integrated structure and function and reduces the cost of additional circulation channels.

[0057] It should be noted that the first hollow profile 101 and the second hollow profile 201 are hollow aluminum profiles for the vehicle body. The hollow structure helps to reduce the heat conduction of coal to a certain extent and has a certain effect on the heat insulation of the truck.

[0058] The shape of the second sealing plate 202 can be set according to the shape of the cross-section of the second hollow cavity of the second hollow profile 201. It is understood that the shape of the second sealing plate 202 is adapted to the shape of the end face of the second hollow profile 201. The adaptation in this article includes the same size and the same shape.

[0059] The second sealing plate 202 is provided with a second pipe joint 203. It can be seen that both ends of the second hollow profile 201 along the extension direction of the second hollow profile 201 have a second sealing plate 202, and the second sealing plate 202 is provided with a second pipe joint 203. Among them, the second pipe joint 203 at one end of the second hollow profile 201 can be connected to the steam source at the unloading site, and the second pipe joint 203 at the other end of the second hollow profile 201 can be connected to the pipeline system at the unloading site for the purpose of recovering low calorific value steam or condensate.

[0060] The support plate 204 is located outside the accommodating space, and the first end of the support plate 204 is connected to the second hollow profile 201. The second end of the support plate 204 is fixedly connected to the base frame 300. The support plate 204 is arranged at an angle to the base frame 300, and the angle of the support plate 204 relative to the base frame 300 is opposite to the angle of the second hollow profile 201 relative to the base frame 300.

[0061] For example, the end of the second hollow profile 201 extending away from the base frame 300 along its extension direction is inclined away from the accommodating space relative to the end of the second hollow profile 201 extending closer to the base frame 300 along its extension direction. The first end of the support plate 204 is inclined closer to the accommodating space relative to the second end. The inclined second hollow profile 201 and the inclined support plate 204 are connected to the base frame 300, forming a stable triangular structure, which helps to improve the strength of the end wall 200.

[0062] The shape and size of the support plate 204 can be set according to different needs, and all are within the protection range. Optionally, the first end of the support plate 204 is fixedly connected to the middle position of the second hollow profile 201 along the extension direction.

[0063] The connection between the support plate 204 and the second hollow profile 201, and between the support plate 204 and the base frame 300, can be, but is not limited to, welding or threaded connection.

[0064] See Figure 4 As shown, the end wall 200 is provided with a plurality of second hollow profiles 201 along the second direction, and adjacent second hollow profiles 201 are fixedly connected.

[0065] In this embodiment, the end wall 200 is arranged with multiple second hollow profiles 201 along a second direction, which increases the area of ​​the end wall 200. This can be understood as the end wall 200 being composed of multiple connected second hollow profiles 201. Dividing the end wall 200 into multiple second hollow profiles 201 divides the overall second hollow cavity into multiple smaller second hollow cavities, which is beneficial for guiding the direction of the air source using these smaller cavities. Furthermore, the smaller volume of the second hollow profiles 201 results in higher strength, thus increasing the overall strength of the end wall 200.

[0066] The dimensions of the second hollow profile 201 along the first direction, the second direction, and the third direction can be set according to different needs, and are not specifically limited here.

[0067] In some embodiments, the second hollow profiles 201 arranged adjacent to each other along the second direction can be connected by welding or by threaded connectors. The connection method of adjacent second hollow profiles 201 is not limited to the above-described connection methods.

[0068] In some embodiments, adjacent second hollow profiles 201 may be connected or isolated from each other (i.e., not connected).

[0069] If adjacent second hollow profiles 201 are connected, openings can be made on the opposite sidewalls of the adjacent second hollow profiles 201 along the second direction, and the openings of the adjacent second hollow profiles 201 can be sealed and connected.

[0070] The adjacent second hollow profiles 201 are connected, allowing the steam source flowing within the adjacent second hollow profiles 201 to flow between them. In some embodiments, the adjacent first hollow profiles 101 are sequentially connected, so that the second hollow cavities of the end wall 200 are connected as a circulation channel. This method can reduce the number of inlets and outlets on the end wall 200 and reduce costs.

[0071] The adjacent second hollow profiles 201 are not interconnected, allowing steam to be injected into each second hollow profile 201. This results in a high steam injection rate per unit time, improving the heat exchange efficiency of the end wall 200. This avoids the problem of uneven temperature distribution in the end wall 200 caused by the steam temperature decreasing after heat exchange during its long-path circulation along the end wall 201. It should be noted that in the configuration where all the second hollow cavities of the second hollow profiles 201 are connected as a single circulation channel, the area of ​​the circulation channel on the end wall 200 is the same as in the configuration where the second hollow cavities of the second hollow profiles 201 are individually arranged.

[0072] In this embodiment of the application, the connecting plate 205 is connected to the end of the second hollow profile that is away from the base frame 300 along the extension direction.

[0073] The connecting plate 205 has an air inlet and an air outlet. Optionally, there is one air inlet and multiple air outlets. For example, the number of air outlets is the same as the number of second hollow profiles 201, and the air outlets are connected to the inlets of the second hollow profiles 201 one by one.

[0074] During the heating process of the vehicle body, the air inlet and the air source can be connected. The hot air entering the air inlet will be distributed to the corresponding second hollow profile 201 through the air outlet to heat the second hollow profile 201.

[0075] Since the connecting plate 205 in this embodiment of the application has only one air inlet, when the end wall 200 needs to be heated, only the air inlet and the air source need to be connected, which helps to reduce the operation steps and improve the efficiency of connecting the vehicle body and the air source.

[0076] In some embodiments, the connecting plate 205 is perpendicular to the base frame 300 to limit the material at the top of the vehicle body, which helps to prevent the material inside the vehicle body from falling out of the containment space.

[0077] In the embodiments of this application, the cross-sectional width of the first hollow profile 101 and the second hollow profile 201 can be 40mm to 70mm, and the wall thickness of the profile can be 2mm to 5mm.

[0078] In addition, this application also discloses a truck, including a vehicle body, wherein the vehicle body is the vehicle body disclosed in the above embodiments. Therefore, the truck with this vehicle body also has all the above-mentioned technical effects, which will not be repeated here.

[0079] 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.

[0080] 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.
