[0046] The present disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted here that the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation of the present disclosure.

[0047] As shown Figures 1 to 2 in the figure, an embodiment of the present disclosure provides a semi-trailer, including a frame, a tank body 1 and a discharge valve 2.

[0048] In the present disclosure, the upper surface of the frame slopes downward from front to back.

[0049] The tank body 1 is arranged on the upper surface of the frame. Under the action of the upper surface of the frame, the tank body 1 also presents a form that slopes downward from front to back.

[0050] It should be noted that Figure 1 the upper surface of the frame in Figure 1 slopes downward from right to left, that is, Figure 2 the direction from right to left of the frame in Figure 2 is the direction from front to back of the frame.

[0051] Wherein, a containing space for loading a liquid medium is provided in the tank body 1. When the tank body 1 is arranged on the frame, the tank body 1 slopes downward from front to back, so that the liquid medium in the tank body 1 can flow towards the rear end of the tank body 1 under the action of gravity.

[0052] The discharge valve 2 is arranged at the bottom of the rear end of the tank body 1. By controlling the opening of the discharge valve 2, the liquid medium in the tank body 1 can be discharged, so as to complete the discharging of the tank body 1.

[0053] In the embodiment of the present disclosure, while making the upper surface of the frame slope downward from front to back, the discharge valve 2 is arranged at the rear end of the tank body 1. Thus, whether the frame is in a coupled state or a decoupled state, it can be ensured that the whole tank body 1 on the frame is in a state of sloping downward from front to back. When the discharge valve 2 is opened, the liquid medium in the tank body 1 flows towards the rear end of the tank body 1 under the action of gravity and is discharged from the inside of the tank body 1 through the discharge valve 2. Furthermore, the difficulty of cleaning the tank body 1 can be reduced to reduce the residual liquid medium in the tank body 1. At the same time, through the cooperation of the frame and the discharge valve 2, the present disclosure makes the discharging of the tank body 1 as complete as possible, so as to reduce the waste of the liquid medium and then save costs.

[0054] It should be noted that the front end and the rear end of the tank body 1 correspond to the front end and the rear end of the frame respectively, that is: the direction from front to back of the tank body 1 is the same as the direction from front to back of the frame.

[0055] Further, the vehicle frame in the present disclosure may include two vehicle longitudinal beams 31 that are parallel and spaced apart, and the vehicle longitudinal beams 31 extend along the longitudinal direction Y. Among them, the lower surface of the vehicle longitudinal beam 31 extends horizontally, that is, the lower surface of the vehicle longitudinal beam 31 is parallel to the horizontal direction. The upper surface of the vehicle longitudinal beam 31 slopes downward from front to back, so that the tank body 1 located on the upper surface of the vehicle longitudinal beam 31 can present a state of sloping downward from front to back.

[0056] Exemplarily, the included angle between the upper surface of the vehicle longitudinal beam 31 and the horizontal plane in the present disclosure may be 1°. While ensuring that the tank body 1 presents a state of sloping downward from front to back to cooperate with the discharge valve 2 located at the bottom of the rear end of the tank body 1 to discharge the liquid medium from the tank body 1 as completely as possible and reduce the residue of the liquid medium in the tank body 1, it can also avoid the problem of unstable center of gravity caused by too large an inclination angle of the tank body 1, and then can reduce or avoid the risk of the semi-trailer tipping backward.

[0057] As Figure 3 shown, in the embodiment of the present disclosure, the vehicle frame may include a plurality of brackets 32. The brackets 32 are arranged on the upper surfaces of the two vehicle longitudinal beams 31 and are connected to the two vehicle longitudinal beams 31. The upper surface of the bracket 32 is a curved arc surface for receiving the tank body 1. By providing the brackets 32 in the present disclosure, the load of the tank body 1 can be evenly transmitted to the vehicle frame, thereby improving the stability of the semi-trailer.

[0058] Among them, the shape of the upper surface of the bracket 32 can be adapted to the shape of the lower surface of the tank body 1, so that at least the upper surface of the bracket 32 can be completely attached to the lower surface of the tank body 1, increasing the contact area between the tank body 1 and the bracket 32, avoiding the phenomenon of stress concentration on the tank body 1 and the bracket 32, and reducing the risk of damage to the tank body 1 and the bracket 32. Both relatively two ends of the tank body 1 in the transverse direction X are in contact with the brackets 32, thereby restricting the lateral movement of the tank body 1 and improving the stability during the driving of the semi-trailer.

[0059] It should be noted that the connection and fixation between the bracket 32 and the tank body 1 can be achieved by welding.

[0060] The plurality of brackets 32 are arranged at intervals along the extending direction of the vehicle longitudinal beam 31, and in the front-to-back direction of the vehicle frame, the height of the top surface of each bracket 32 decreases, so that the tank body 1 arranged on the upper surface of the bracket 32 can present a state of sloping downward from front to back.

[0061] In addition, the bracket 32 can also extend upward so that the bracket 32 contacts a part of the upper surface of the tank body 1. While increasing the contact surface between the bracket 32 and the tank body 1 to reduce the contact stress, it can also enhance the limiting effect of the bracket 32 on the tank body 1.

[0062] It should be noted that the upper surface and the lower surface of the tank body 1 mentioned above refer to: the outer surface of the tank body 1 is divided into the upper surface and the lower surface with the horizontal plane where the long axis of the tank body 1 is located as the boundary.

[0063] Further, such as Figures 2 to 4 As shown, the vehicle frame may further include multiple sets of mounting parts, each corresponding one to a bracket 32. Each set of mounting parts may include two mounting angles 33, and the two mounting angles 33 in each set of mounting parts are symmetrically arranged on the two vehicle longitudinal beams 31. The lower ends of the mounting angles 33 are connected to the vehicle longitudinal beams 31, and the upper ends of the mounting angles 33 are embedded in the bracket 32 and fixedly connected to the bracket 32.

[0064] For example, the mounting angle 33 may include a first mounting plate parallel to the upper surface of the longitudinal beam 31 and a second mounting plate located on the side of the first mounting plate facing away from the longitudinal beam 31. The first mounting plate is placed on the upper surface of the longitudinal beam 31 and is fixedly connected to the longitudinal beam 31. The first mounting plate and the longitudinal beam 31 may be connected and fixed by bolts. The second mounting plate is perpendicular to the first mounting plate and is fixedly connected to the first mounting plate. Mounting holes may be provided at positions corresponding to the bracket 32 and the second mounting plate. The second mounting plate is embedded in the interior of the tank body 1 through the mounting holes and is welded to the bracket 32.

[0065] The present disclosure provides a mounting angle 33, thereby achieving a connection between the bracket 32 and the vehicle longitudinal beam 31 while also achieving a certain buffering performance between the bracket 32 and the vehicle longitudinal beam 31. Compared with the solution of directly welding the bracket 32 to the vehicle longitudinal beam 31, the present disclosure provides a mounting angle 33 between the bracket 32 and the vehicle longitudinal beam 31, which can reduce the impact force between the bracket 32 and the vehicle longitudinal beam 31 when impacted, thereby reducing the risk of damage to the bracket 32 and the vehicle longitudinal beam 31 and extending the service life of the bracket 32 and the vehicle longitudinal beam 31.

[0066] In addition, the vehicle frame may further include a plurality of vehicle cross beams connected between the two vehicle longitudinal beams 31 , and the plurality of vehicle cross beams are arranged at intervals along the extending direction of the vehicle longitudinal beams 31 .

[0067] In the present disclosure, the cross beam can correspond to the bracket 32 one by one, and in this case, the upper surface of the cross beam contacts the lower surface of the corresponding bracket 32. By providing the cross beam, the structural strength of the frame can be strengthened, thereby strengthening the support performance of the frame for the tank body 1 and reducing the risk of frame damage.

[0068] However, the present invention is not limited thereto. In the present invention, the number of cross beams may be greater than the number of brackets 32 , or the number of cross beams may be less than the number of brackets 32 , depending on the actual situation.

[0069] In the embodiment of the present disclosure, the cross-section of the tank body 1 may be elliptical, and the diameter of the tank body 1 in the left-right direction is greater than the diameter in the up-down direction.

[0070] In the above, the left - right direction of the middle tank body 1 refers to the transverse direction X, and the up - down direction refers to the vertical direction Z.

[0071] It should be noted that the ellipse in the present disclosure can be either a standard ellipse or an approximate ellipse with a major axis and a minor axis.

[0072] Compared with the tank body 1 whose diameter in the up - down direction is the same and the cross - section is circular, in the present application, the diameter of the elliptical tank body 1 in the left - right direction is larger, so that the volume of the entire tank body 1 can be increased. In addition, by making the diameter of the tank body 1 in the left - right direction larger than that in the up - down direction, the center of gravity of the tank body 1 can be lowered, thereby improving the stability of the tank body 1 and reducing the risk of the tank body 1 tilting during transportation, so as to improve the safety of semi - trailer transportation.

[0073] In the embodiment of the present disclosure, the tank body 1 may include a cylindrical body 11 and a front head and a rear head 12 arranged at the front and rear ends of the cylindrical body 11 respectively. The cylindrical body 11 can be a hollow elliptical cylinder, and both ends of the cylindrical body 11 have openings. The front head and the rear head 12 respectively cover the openings at the front and rear ends of the cylindrical body 11 and are fixedly connected to the cylindrical body 11, thereby forming a receiving space for carrying liquid medium.

[0074] Among them, the discharge valve 2 can be arranged at the bottom of the rear head 12. Thus, when the discharge valve 2 is opened, the liquid medium in the tank body 1 can flow to the rear end of the tank body 1 and be discharged from the tank body 1 through the discharge valve 2.

[0075] However, not limited thereto, the discharge valve 2 in the present disclosure can also be arranged on the cylindrical body 11.

[0076] Exemplarily, the discharge valve 2 can be arranged at the bottom of one end of the cylindrical body 11 close to the rear head 12.

[0077] Such as Figure 1 、 Figures 5 to 8 As shown, in the embodiment of the present disclosure, a plurality of anti - wave plates can be arranged inside the tank body 1. The plurality of anti - wave plates are arranged at equal intervals along the axial direction of the tank body 1, and the anti - wave plates are fixedly connected to the inner side wall of the tank body 1. By arranging the anti - wave plates in the tank body 1, the present disclosure can reduce the fluctuation and impact of the liquid medium in the tank body 1, thereby improving the stability during the driving of the semi - trailer.

[0078] Specifically, the plurality of anti - wave plates in the present disclosure can include: at least one V - type anti - wave plate 4 and at least two bulge - type anti - wave plates 5.

[0079] Among them, the bulge - type anti - wave plate 5 has an arc - shaped structure with the convex surface facing the front end of the tank body 1, and the bulge - type anti - wave plates 5 are arranged on the opposite sides of the V - type anti - wave plate 4.

[0080] It should be noted that the structural strength of the expansion type wave baffle 5 is greater than that of the V type wave baffle 4. In the present disclosure, by arranging the expansion type wave baffle 5 on the opposite sides of the V type wave baffle 4, the impact of the liquid medium on the V type wave baffle 4 can be reduced, so as to reduce the risk of damage to the V type wave baffle 4, thereby ensuring the overall impact resistance of the wave baffle.

[0081] A circular manhole 51 can be provided on the expansion type wave baffle 5, and the staff can freely walk inside the tank body 1 through the circular manhole 51, so as to facilitate the cleaning and maintenance of the inside of the tank body 1 by the staff.

[0082] Both the front and back sides of the V type wave baffle 4 have a plurality of V-shaped concave and convex surfaces, which can strengthen the structural strength of the V type wave baffle 4 and reduce the risk of damage to the V type wave baffle 4. In addition, except for the part welded to the inner wall of the tank body 1, there are no dead corners in other places of the V type wave baffle 4, so as to reduce the cleaning difficulty of the wave baffle and reduce the residue of the liquid medium inside the tank body 1.

[0083] It should be noted that the mass of the V type wave baffle 4 in the present disclosure is less than that of the expansion type wave baffle 5. Therefore, in the present disclosure, by arranging the expansion type wave baffle 5 and the V type wave baffle 4 in the tank body 1, while ensuring the overall structural strength of the wave baffle to reduce the impact force of the liquid medium inside the tank body 1, the overall mass of the tank body 1 can also be reduced, thereby saving the energy consumption of transporting the tank body 1 by the semi-trailer and saving the transportation cost.

[0084] The V type wave baffle 4 can also include a V-shaped manhole 41, and the staff can freely walk inside the tank body 1 through the V-shaped manhole 41, so as to facilitate the cleaning and maintenance of the inside of the tank body 1 by the staff.

[0085] Among them, the shape of the V-shaped manhole 41 can be a regular V shape, but it is not limited thereto. The open end of the V-shaped manhole 41 can also be slightly inclined in the direction of the opposite ends of the long axis of the tank body 1.

[0086] In some embodiments of the present disclosure, four wave baffles can be provided inside the tank body 1. At this time, the four wave baffles can include one V type wave baffle 4 and three expansion type wave baffles 5, wherein the expansion type wave baffles 5 are located on the opposite sides of the V type wave baffle 4 in the longitudinal direction Y. However, it is not limited thereto. The four wave baffles can also include two V type wave baffles 4 and two expansion type wave baffles 5, which can be determined according to the actual situation.

[0087] It should be noted that the number of wave baffles inside the tank body 1 is not limited to four. The number of wave baffles provided inside the tank body 1 in the present disclosure can also be three, five, six, etc., which can be set according to the shape of the tank body 1 specifically.

[0088] Such as Figure 9As shown, in the embodiments of the present disclosure, at least two top manholes 6 may be provided at the top of the tank body 1.

[0089] Specifically, two top manholes 6 may be provided at the top of the tank body 1. The two top manholes 6 may be provided at opposite ends of the tank body 1. However, this is not limited thereto, and the two top manholes 6 may also be provided at any position on the top of the tank body 1, and may be specifically set according to the actual situation.

[0090] In addition, the number of top manholes 6 provided at the top of the tank body 1 in the present disclosure may also be three, four, five, etc., and no specific limitation is made here.

[0091] Furthermore, at least two internal ladders 7 may be provided inside the tank body 1, and the internal ladders 7 extend from the bottom of the tank body 1 to the manholes.

[0092] The number of internal ladders 7 and top manholes 6 in the present disclosure may correspond one by one, that is, one top manhole 6 is correspondingly provided with one internal ladder 7. Staff can observe the situation inside the tank body 1 from the top manhole 6, and can also climb onto the internal ladder 7 through the top manhole 6 to enter the tank body 1 and perform maintenance and cleaning on the inside of the tank body 1.

[0093] It should be noted that the internal ladder 7 in the present disclosure may be an integral ladder. The integral ladder has a stable structure, is easy to install, and has no dead corners except at the connection with the inside of the tank body 1, which can thus be beneficial to the cleaning of the inside of the tank body 1 and can reduce the residue of the liquid medium inside the tank body 1.

[0094] It should be noted that the liquid medium carried inside the tank body 1 in the present disclosure may be edible oil. At this time, the tank body 1 may be made of food-grade austenitic stainless steel material. While improving the structural strength of the tank body 1 to enhance the safety of transportation, it can also reduce the food safety risk of the edible oil. However, this is not limited thereto. The tank body 1 may also be used to carry other liquid media other than edible oil, and the tank body 1 may also be made of other materials with good structural strength other than austenitic stainless steel material.
