[0039] In the related art, the powder tank truck includes a vehicle body and a tank body arranged on the vehicle body, the tank body is fixed on the vehicle body through a plurality of saddles, the tank body and the vehicle body are integrated, after the delivery arrives at the destination, the tank truck can only wait until the tank body unloads the material before leaving, which leads to low transportation efficiency and turnover efficiency, and there are many limitations for railway, sea transportation and combined transportation of the tank truck, which leads to inflexible transportation mode. To solve this problem, the present application embodiment provides a tank container and a powder tank truck.

[0040] Referring to Figures 1 to 4 The present embodiment provides a tank container, which includes a tank body 1, a frame 2, two skirts 3 and saddles 4. The tank body 1 serves as a container and has an internal cavity for storing the material to be transported. The two ends of the tank body 1 in the longitudinal direction are respectively set as a first end and a second end, the first end of the tank body 1 is provided with a discharge port 12 for discharging material outward, the material in the cavity is discharged outward through the discharge port 12, and a discharge valve can be arranged at the discharge port 12 to open and close the discharge port 12.

[0041] In some embodiments, the frame 2 is used to support the tank body 1, and the tank body 1 and the frame 2 are fixedly connected as a whole to form a tank container. The frame 2 comprises two end frames 20 arranged at intervals in the longitudinal direction, a bottom beam 21 and a top beam 22 connecting the two end frames 20, and the frame 2 as a whole can form a rectangular frame structure, thereby facilitating hoisting and stacking for railway or sea transportation, and the transportation mode of the tank container is more flexible. By reasonably setting the size of the frame 2, the tank container can be a standard tank container of 20 feet, of course, it can also be a standard tank container of other volumes.

[0042] Specifically, the end frame 20 comprises two vertical columns 200 arranged in parallel at intervals, a top cross beam 201 connecting the two vertical columns 200, and a bottom cross beam 202 connecting the two vertical columns 200. The top cross beam 201 and the bottom cross beam 202 are arranged in parallel, the top cross beam 201 connects the top ends of the two vertical columns 200, and the bottom cross beam 202 connects the bottom ends of the two vertical columns 200, so that the end frame 20 as a whole has a rectangular structure.

[0043] In some embodiments, the end frame 20 further comprises an inclined brace arranged obliquely, which is used to connect the vertical column 200, the top cross beam 201 and the bottom cross beam 202, and can enhance the structural strength of the end frame 20. The inclined brace comprises a first inclined brace 203 connecting the middle part of the top cross beam 201 and the vertical column 200, and a second inclined brace 204 connecting the middle part of the bottom cross beam 202 and the vertical column 200. Connecting the first inclined brace 203 to the middle part of the top cross beam 201 and the vertical column 200 can make the force on the top cross beam 201 and the vertical column 200 more balanced, and similarly, connecting the second inclined brace 204 to the middle part of the bottom cross beam 202 and the vertical column 200 can make the force on the bottom cross beam 202 and the vertical column 200 more balanced, thereby enhancing the structural strength of the end frame 20. Of course, in other embodiments, the first inclined brace 203 and the second inclined brace 204 can also be connected to other positions of the top cross beam 201 and the bottom cross beam 202, such as 1 / 3, 2 / 3 of the length direction, etc.

[0044] Since the end frame 20 is provided with two vertical columns 200, each vertical column 200 corresponds to a first inclined brace 203 and a second inclined brace 204, and each vertical column 200, the top cross beam 201, the bottom cross beam 202, the first inclined brace 203 and the second inclined brace 204 form a multi-deformation structure. In this embodiment, the positions where the two first inclined braces 203 are connected to the top cross beam 201 can be arranged on both sides of the center of the top cross beam 201, i.e. on the middle part of the top cross beam 201, the positions where the two second inclined braces 204 are connected to the bottom cross beam 202 can be arranged on both sides of the center of the bottom cross beam 202, i.e. on the middle part of the bottom cross beam 202, and the positions where the first inclined brace 203 and the second inclined brace 204 corresponding to the same vertical column 200 are connected to the vertical column 200 can be arranged on both sides of the center of the vertical column 200, i.e. on the middle part of the vertical column 200.

[0045] In some embodiments, the first diagonal brace 203 and the top crossbeam 201 and the column 200 can be fixed by welding, and the second diagonal brace 204 and the bottom crossbeam 202 and the column 200 can be fixed by welding, so as to improve the connection stability of the diagonal brace, the top crossbeam 201, the bottom crossbeam 202 and the column 200. Of course, the first diagonal brace 203 and the top crossbeam 201 and the column 200 can also be connected by bolts, and the second diagonal brace 204 and the bottom crossbeam 202 and the column 200 can also be connected by bolts, so as to facilitate installation and disassembly.

[0046] In some embodiments, the bottom beam 21 is connected to the bottom end of the end frame 20. The bottom beam 21 can be arranged at intervals in the transverse direction, and is connected to the connection between the two ends of the bottom crossbeam 202 and the column 200 in the end frame 20. The bottom beam 21, the bottom crossbeam 202 and the column 200 can be connected by an angle piece, so that the three are firmly connected. Similarly, the top beam 22 can be arranged at intervals in the transverse direction, and the top beam 22 and the bottom beam 21 are arranged in parallel at intervals in the vertical direction, so as to be connected to the connection between the two ends of the top crossbeam 201 and the column 200 in the end frame 20. The top beam 22 and the top crossbeam 201 and the column 200 can also be connected by an angle piece, so that the three are firmly connected. By arranging the top beam 22 and the bottom beam 21 to connect the two end frames 20, the frame 2 is a whole structure, so as to facilitate overall hoisting and stacking of the frame 2.

[0047] In some embodiments, a space is formed between the top beam 22 and the bottom beam 21 for accommodating the tank body 1. The tank body 1 is arranged between the top beam 22 and the bottom beam 21, so as to avoid extending out of the frame 2 and affecting the installation between the frame 2 and the vehicle body 5 and the stacking of the tank containers.

[0048] In some embodiments, two skirts 3 are fixed respectively at the two longitudinal ends of the tank body 1, and are arranged in one-to-one correspondence with the two end frames 20, so as to connect the end frame 20 and the tank body 1 as a whole in the longitudinal direction, and provide support for the tank body 1. The skirt 3 is at least partially connected to the outer periphery of the tank body 1, so as to improve the connection strength between the skirt 3 and the tank body 1.

[0049] In some embodiments, the saddle 4 is fixed on the bottom beam 21, and the saddle 4 has a concave bearing surface 40 which is adapted to the circumferential contour shape of the bottom of the tank body 1 to bear the tank body 1, so as to support the tank body 1 in the vertical direction, improve the stress area of the bottom of the tank body 1, and avoid stress concentration. It should be noted that when the tank body 1 is a whole cylinder, the bearing surface 40 is generally arc-shaped, so as to better wrap the bottom of the tank body 1.

[0050] In the embodiment, the tank body 1 is fixed in the frame 2 to form a tank container by arranging the frame 2 for supporting the tank body 1, fixing the tank body 1 at both ends to the two end frames 20 of the frame 2 through the two skirts 3, and fixing the bottom of the tank body 1 to the bottom beam 21 of the frame 2 through the saddle 4. The tank container can be arranged on the vehicle body 5 of the powder tank vehicle, and the tank container and the vehicle body 5 can be arranged separately, thereby improving the transportation efficiency and turnover efficiency of the powder tank vehicle. Meanwhile, the separated tank container can be used as a container to participate in various transportation modes such as railway transportation, sea transportation and combined transportation, thereby improving the transportation flexibility.

[0051] In some embodiments, the saddle 4 includes a ring-shaped support plate 41, a bottom plate 42 and a plurality of reinforcing rib plates 43. The ring-shaped support plate 41 is used to support the bottom of the tank body 1, and the top surface of the ring-shaped support plate 41 is provided with the abutment surface 40. The two ends of the ring-shaped support plate 41 can extend to the outer peripheral wall in the width direction of the tank body 1, so as to cover the tank body 1 as much as possible and improve the contact area with the tank body 1.

[0052] In some embodiments, the bottom plate 42 extends along the width direction of the tank body 1, and the two ends of the bottom plate 42 are fixedly connected to the two bottom beams 21, respectively. The bottom plate 42 is arranged in the frame 2, and the bottom plate 42 and the ring-shaped support plate 41 correspond to each other in the up-down direction. The plurality of reinforcing rib plates 43 are arranged in the width direction of the tank body 1 at intervals, and the two ends of the reinforcing rib plate 43 are fixedly connected to the bottom surface of the ring-shaped support plate 41 and the top surface of the bottom plate 42, respectively. Thus, in the up-down direction, the ring-shaped support plate 41 transmits the force to the bottom plate 42 through the reinforcing rib plate 43, and then the bottom plate 42 transmits the force to the frame 2, so as to support the tank body 1. The reinforcing rib plate 43, the ring-shaped support plate 41 and the bottom plate 42 can be fixed by welding or by bolts. Since the distance between the ring-shaped support plate 41 and the bottom plate 42 in the width direction of the tank body 1 is not the same, the height between the plurality of reinforcing rib plates 43 is also different, as long as the reinforcing rib plate 43 can be connected to the corresponding position of the ring-shaped support plate 41 and the bottom plate 42.

[0053] In some embodiments, the saddle 4 further includes two connecting plates 44 arranged in the width direction of the tank body 1 at intervals. The two connecting plates 44 are arranged at opposite ends of the ring-shaped support plate 41, which can be the two ends of the ring-shaped support plate 41 in the length direction of the tank body 1. The connecting plate 44 connects the bottom surface of the ring-shaped support plate 41 and the top surface of the bottom plate 42, so as to further improve the structural strength of the saddle 4 in cooperation with the plurality of reinforcing rib plates 43, so as to more stably support the tank body 1. The two connecting plates 44, the ring-shaped support plate 41 and the bottom plate 42 can enclose a closed space, and the plurality of reinforcing rib plates 43 are arranged in the space, so as to avoid the reinforcing rib plate 43 from being exposed, and improve the integrity and aesthetic appearance of the saddle 4.

[0054] In some embodiments, the connecting plate 44 can also be provided only one, connected to the same end of the annular support plate 41 and the bottom plate 42.

[0055] In the present embodiment, since the tank body 1 is fixedly connected with the two end frames 20 through the two skirts 3 at both ends, the saddle 4 can be provided one, of course, to ensure that the tank body 1 and the frame 2 are connected stably, the saddle 4 can also be provided multiple, which are arranged along the length direction of the tank body 1.

[0056] In some embodiments, the longitudinal end of the tank body 1 is conical, so that the bottom of the longitudinal end of the tank body 1 is the lowest end, and the discharge port 12 is arranged at the lowest end. When discharging, the material in the cavity can be collected at the lowest end, thereby facilitating discharging.

[0057] In some embodiments, the tank body 1 includes a cylinder body 10 and two end covers 11 arranged at both ends of the cylinder body 10. The end covers 11 are used to seal both ends of the cylinder body 10, so that the internal space of the cylinder body 10 is sealed, and the cavity is formed inside the cylinder body 10. The discharge port 12 is arranged on one of the two end covers 11. The two end covers 11 are fixedly connected with the two end frames 20 through the two skirts 3, so as to fixedly connect the tank body 1 and the end frame 20. Among them, the end cover 11 where the discharge port 12 is arranged is conical and irregular, and the end cover 11 away from the discharge port 12 is regular hemispherical or cylindrical. The saddle 4 and the bottom of the cylinder body 10 are fixedly connected to support the cylinder body 10.

[0058] In some embodiments, of the two skirts 3, the one close to the discharge port 12 is the first skirt 30, and the one away from the discharge port 12 is the second skirt 31. The first skirt 30 is arc-shaped and along the vertical direction. The first skirt 30 is arranged above the discharge port 12 in the vertical direction, so that the first skirt 30 and the corresponding end cover 11 have more contact area, and the connection between the first skirt 30 and the end cover 11 is more stable. The first skirt 30 is fixedly connected with the end frame 20 and the tank body 1 at both longitudinal ends of the tank body 1. Specifically, the first skirt 30 is fixedly connected with the inclined support and the outer wall of the end cover 11 where the discharge port 12 is arranged at both longitudinal ends of the tank body 1. The fixed connection can be achieved by welding. Since the first skirt 30 is arc-shaped, the first skirt 30 can be fixedly connected with the first inclined support 203 and the second inclined support 204 connected with the top cross beam 201.

[0059] In some embodiments, the angle of the arc of the first skirt 30 can be obtuse or acute, which is as close as possible to the outer periphery of the end cover 11, which can improve the connection strength and stability of the first skirt 30 and the end cover 11.

[0060] In some embodiments, the second skirt 31 is in the shape of a closed ring, is sleeved on the outer periphery of the tank body 1, can have a supporting effect on one end of the tank body 1 in the longitudinal direction, and can be fixedly connected with the outer periphery of the tank body 1 by welding or bolt connection or the like. Specifically, the second skirt 31 is sleeved on the outer peripheral wall of the head 11 away from the discharge port 12, and one end of the second skirt 31 away from the first skirt 30 is fixedly connected with the inclined support of the corresponding end frame 20. Since the second skirt 31 is in the shape of a ring, it can be fixedly connected with all the first inclined supports 203 and the second inclined supports 204 in the inclined support, so as to improve the connection stability.

[0061] In the present embodiment, since the first skirt 30 is in the shape of an arc, the contact area of the first skirt 30 with the head 11 is smaller than the contact area of the second skirt 31 with the head 11, so that the connection strength of the first skirt 30 to the tank body 1 is smaller than the connection strength of the second skirt 31 to the tank body 1. The saddle 4 can be arranged close to the discharge port 12, so that the saddle 4 can support one end of the tank body 1 in cooperation with the first skirt 30, and both ends of the tank body 1 are stably connected with the frame 2.

[0062] In some embodiments, the longitudinal dimension of the second skirt 31 is not greater than the longitudinal dimension of the first skirt 30. The longitudinal dimension of the second skirt 31 can be equal to or smaller than the longitudinal dimension of the first skirt 30. Since the first skirt 30 is in the shape of an arc, and the head 11 connected with the first skirt 30 is in the shape of a cone, in order to avoid the bottom end of the head 11 protruding outward of the end frame 20, the distance between the outer periphery of the head 11 connected with the first skirt 30 and the end frame 20 is greater than or equal to the distance between the head 11 connected with the second skirt 31 and the corresponding end frame 20. By making the longitudinal dimension of the first skirt 30 greater than or equal to the longitudinal dimension of the second skirt 31, both ends of the first skirt 30 can be fixedly connected with the end frame 20 and the corresponding head 11.

[0063] In some embodiments, the radius of the circle on which the first skirt 30 is located is not greater than the inner diameter of the tank body 1. The radius of the circle on which the first skirt 30 is located can be smaller than or equal to the inner diameter of the tank body 1. Since the first skirt 30 is in the shape of an arc, and the head 11 connected with the first skirt 30 is in the shape of a cone, by making the radius of the circle on which the first skirt 30 is located smaller than or equal to the inner diameter of the tank body 1, the first skirt 30 can have more connection areas with the head 11, so as to make the connection between the first skirt 30 and the head 11 more stable, and improve the connection strength of the tank body 1 and the end frame 20.

[0064] Referring to Figure 5 and Figure 6In the embodiment, the powder tank truck further comprises a tank container arranged on the vehicle body 5, and the tank container is detachably arranged on the vehicle body 5, so that after the powder tank truck is transported to a destination, the tank container can be separated from the vehicle body 5, the vehicle body 5 can transport other tank containers alone, the transportation efficiency and turnover efficiency of the powder tank truck are improved, and meanwhile, the separated tank container can be used in the form of a container to participate in various transportation modes such as railway transportation, sea transportation and combined transportation, and the transportation flexibility is improved.

[0065] In some embodiments, when the tank container is arranged on the vehicle body 5, one end of the tank container can be jacked by a driving device, so that the tank container is inclined relative to the vehicle body 5, thereby facilitating unloading. When the tank container is arranged on the vehicle body 5, the first end of the tank body 1 faces the rear side direction of the vehicle body 5, and the second end of the tank body 1 faces the front side direction of the vehicle body 5, according to the cab of the vehicle body 5 as the front side direction reference. During unloading, the second end of the tank body 1 is inclined upward relative to the first end.

[0066] Although the present application has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. Since the present application can be embodied in various forms without departing from the spirit or essential characteristics thereof, it is understood that the embodiments are not limited to any particular combinations of the specified details.
