Description

Technical Field

[0001] This utility model relates to the field of cryogenic storage and transportation equipment technology, and in particular to a tank truck and its reinforcing structure. Background Technology

[0002] For tank trucks used for storing and transporting cryogenic liquids, reinforcing rings are an indispensable strengthening structure, which can increase the axial moment of inertia of the tank sections to meet stability requirements.

[0003] Currently, tanks composed of two cylindrical sections generally lack external reinforcement in the front section or only reinforce the lower half of it. Where reinforcement is present on the exterior of the front section, it typically employs a U-shaped or semi-circular reinforcing ring, which is a regular annular shape, meaning the spacing between its inner and outer diameters is consistent throughout the axial direction. However, for conical front sections, the axial width of the reinforcing ring creates gaps when it fits snugly against the front section, thus hindering its effective reinforcement. Utility Model Content

[0004] The purpose of this utility model is to provide a tank truck and its reinforcing structure. By improving the reinforcing structure, the reinforcing structure can be completely fitted to the outer periphery of the front cylindrical section of the tank truck body, thereby eliminating the gap between the reinforcing structure and the front cylindrical section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: According to one aspect of this application, a reinforcing structure is provided for the tank body of a tank truck, the reinforcing structure comprising: A reinforcing body has two opposite ends that are through along the axial direction, and the inner sidewall of the reinforcing body is inclined inward from one end to the other along the axial direction. The bending portion is provided at least one end of the inner circumferential side of the reinforcing body along the axial direction; The inner circumference of the reinforcing body and the inner circumference of the bent portion are both used to fit and fix to the outer circumference of the front cylindrical section of the tank.

[0006] In some embodiments, the outer sidewall of the reinforcing body has an intersection line with any plane extending along its axial direction, the intersection line extending along the axial direction of the reinforcing body.

[0007] In some embodiments, the reinforcing body has an inner peripheral opening; The reinforcing body includes a main body and two reinforcing parts, with the two reinforcing parts located at both axial ends on the inner circumferential side of the main body; one of the reinforcing parts protrudes inward from the other reinforcing part.

[0008] In some embodiments, the two reinforcing portions are parallel; each reinforcing portion is perpendicular to the main body portion; One of the reinforcing parts has a dimension range of less than or equal to 55 mm along the inward and outward directions; the other reinforcing part has a dimension range of less than or equal to 60 mm along the inward and outward directions.

[0009] In some embodiments, the bent portion is disposed on the inner side of the reinforcing portion and protrudes outward from the reinforcing portion along the axial direction; The bent portion and the reinforcing portion have a rounded transition; each reinforcing portion and the main body portion have a rounded transition; The bent portion and the reinforcing portion are integrally formed.

[0010] In some embodiments, the two axial ends of the reinforcing body are a first end and a second end, respectively, with the first end protruding inward from the second end; The bending portion is provided at the first or second end of the reinforcing body. The bending portion at the first end is inclined inward in a direction away from the reinforcing body, and the bending portion at the second end is inclined outward in a direction away from the reinforcing body.

[0011] In some embodiments, the reinforcing body has bending portions at both axial ends, and the two bending portions are arranged collinearly.

[0012] In some embodiments, the reinforcing structure is arc-shaped; The central angle of the reinforcing structure ranges from 120° to 360°.

[0013] In some embodiments, when the central angle of the reinforcing structure is less than 360°, the reinforcing structure has two free ends, which are spaced apart in the circumferential direction of the reinforcing structure; the outer side of each free end is inclined from the outside to the inside toward the interval between the two free ends.

[0014] According to another aspect of this application, this application also provides a tank truck, comprising: Transport vehicle; A tank body is mounted on the transport vehicle; the tank body includes a front cylindrical section and a rear cylindrical section connected along its axial direction; at least the lower part of the front cylindrical section is inclined from rear to front toward its axis; At least one of the reinforcing structures described above is fitted and fixed to the outer periphery of the front cylinder section, and the inner sidewall of the reinforcing body of the reinforcing structure is inclined toward the front cylinder section from back to front.

[0015] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this application, the inner wall of the reinforcing body is inclined inward from one end to the other along the axial direction. That is, the diameter of the shape formed by the inner peripheral wall of the reinforcing body gradually decreases. This makes it easier for the inner peripheral side of the reinforcing body to adapt to the shape of the front cylinder section, thereby eliminating the gap between the reinforcing body and the front cylinder section. This facilitates the complete fit and fixation of the inner peripheral side of the reinforcing body to the outer peripheral side of the front cylinder section, increasing the contact area and connection area between the reinforcing body and the front cylinder section. At the same time, since the inner peripheral side of the reinforcing body has a bent portion at least at one end along the axial direction, and the bent portion is used to fit and fix to the outer peripheral side of the front cylinder section, the setting of the bent portion strengthens the structural strength of the reinforcing structure, increases the contact area and connection area between the reinforcing structure and the outer peripheral side of the front cylinder section, thereby improving the connection strength between the reinforcing structure and the front cylinder section. Moreover, after the reinforcing structure is fixed to the top surface of the support seat of the tank truck, the above design can also improve the support stability of the front cylinder section.

[0027] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0028] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0029] Furthermore, 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 the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] This application provides a tank truck, including a transport vehicle, a tank body mounted on the transport vehicle, and a reinforcing structure that is fitted and fixed to the outer periphery of the tank body.

[0031] The transport vehicle can be a semi-trailer, and the transport vehicle includes a chassis.

[0032] The tank body is mounted on a chassis. Optionally, the tank truck also includes multiple support seats, which are spaced apart along the axial direction of the tank body on the chassis, and the tank body is fixed to the multiple support seats. Specifically, the top surface of the support seat is concave downwards, forming an arc shape with a certain length (set according to actual needs) along the axial direction of the tank body. The top surface of the support seat intersects with any plane extending along the axial direction of the tank body, and this intersection line extends along the axial direction of the tank body.

[0033] Figure 1 This is a schematic diagram of the tank structure in this embodiment.

[0034] refer to Figure 1 The tank body 200 includes a front cylindrical section 210 and a rear cylindrical section 220 connected along its axial direction. The tank body 200 is mounted on the frame with the front cylindrical section 210 in front and the rear cylindrical section 220 in the rear.

[0035] It should be noted that the front-back direction in this article is the same as the axial direction of the tank 200, while the front-back direction refers to the front-back direction in the conventional sense of a transport vehicle. Furthermore, for ease of description, the direction perpendicular to the axial direction of the tank 200 within the same horizontal plane is considered the left-right direction, which is actually the left-right direction in the conventional sense of a transport vehicle.

[0036] The front cylindrical section 210 has at least its lower part inclined toward its axis from back to front. That is, the diameter of the front cylindrical section 210 gradually decreases from back to front, making the front cylindrical section 210 conical. This results in a gap between the outer periphery of the front cylindrical section 210 and the top surface of the support when the tank 200 is placed on the support, and the gap gradually increases from back to front.

[0037] Optionally, the rear cylinder section 220 is provided with multiple reinforcing rings spaced axially along its outer periphery to enhance its strength. The rear cylinder section 220 is fixed to the support base via these reinforcing rings. Specifically, each support base corresponding to the rear cylinder section 220 is associated with a reinforcing ring, and the outer periphery of the reinforcing ring is bonded to and welded to the top surface of the support base.

[0038] The reinforcing structure 100 is fitted and fixed to the outer periphery of the front cylinder section 210, wherein the front cylinder section 210 is fixed to the support base through the reinforcing structure 100.

[0039] The following detailed description of specific embodiments of the reinforcing structure 100 of this application, in conjunction with the accompanying drawings, provides a comprehensive overview.

[0040] Figure 2 This is a schematic diagram of the reinforcing structure 100 in this embodiment. Figure 3 This is a side view of the reinforcing structure 100 in this embodiment. Figure 4 This is a cross-sectional view of the reinforcing structure 100 in this embodiment.

[0041] refer to Figures 2-4 In this embodiment, the reinforcing structure 100 is arc-shaped. The central angle of the reinforcing structure 100 ranges from 120° to 360°.

[0042] In this embodiment, the reinforcing structure 100 can be a complete circle with a central angle of 360°.

[0043] Figure 5 This is a schematic diagram of the reinforcing structure 100 in some embodiments. Figure 6 for Figure 5 Installation effect diagram of reinforced structure 100. Figure 7 This is a schematic diagram of the reinforcing structure 100 in some other embodiments. Figure 8 for Figure 7 Installation effect diagram of the reinforced structure 100.

[0044] exist Figures 5-8In the illustrated embodiment, the reinforcing structure 100 is fan-shaped with a central angle less than 360°. The reinforcing structure 100 has two free ends 110. Optionally, the two free ends 110 are spaced apart circumferentially from the reinforcing structure 100. The outer sides of each free end 110 slope inwards towards the gap between the two free ends 110. This design makes the outer sides of the free ends 110 sloped, which helps to disperse the stress in the reinforcing structure 100 between the free ends 110 and the front cylinder section 210, reducing local stress concentration and making stress transmission more uniform. Furthermore, the sloped surface design avoids sharp edges on the free ends 110, reducing the risk of scratches during on-site installation and improving aesthetics.

[0045] refer to Figures 5-8 When the central angle of the reinforcing structure 100 is less than 360°, the reinforcing structure 100 is arranged in a ring around the front cylindrical section 210 from bottom to top. Furthermore, the axis of symmetry of the reinforcing structure 100 (extending along its axial direction) and the axis of the front cylindrical section 210 are located in the same vertical plane. This ensures that the reinforcing structure 100 is symmetrically distributed about the vertical plane containing the axis of the front cylindrical section 210, thus providing uniform support on both sides of the front cylindrical section 210. This balances the forces on both sides of the front cylindrical section 210 and improves its stability. At this time, the outer side of the free end 110 of the reinforcing structure 100 slopes inward from bottom to top.

[0046] refer to Figures 2-4 The reinforcing structure 100 includes a reinforcing body 1 and a bending part 2.

[0047] The reinforcing body 1 extends through both ends along the axial direction, meaning it is arc-shaped. Specifically, the reinforcing body 1 is a complete circular ring with a central angle of 360°. Figures 5-8 In the embodiment shown, the reinforcing body 1 is fan-shaped with a central angle of less than 360°. At this time, the outer side of the free end 110 of the reinforcing body 1 is an inclined surface.

[0048] The inner circumferential side of the reinforcing body 1 is used to fit and fix to the outer circumference of the front cylindrical section 210 of the tank body 200. The inner wall of the reinforcing body 1 slopes inward from one end to the other along the axial direction, meaning the diameter of the shape formed by the inner circumferential wall of the reinforcing body 1 gradually decreases. This facilitates the fitting of the inner circumferential side of the reinforcing body 1 to the shape of the front cylindrical section 210, eliminating the gap between the reinforcing body 1 and the front cylindrical section 210. This allows the inner circumferential side of the reinforcing body 1 to be completely fitted and fixed to the outer circumference of the front cylindrical section 210, increasing the contact area and connection area between the reinforcing body 1 and the front cylindrical section 210. This improves the connection strength between the reinforcing structure 100 and the front cylindrical section 210. Furthermore, after the reinforcing structure 100 is fixed to the top surface of the support base, this design also improves the support stability of the front cylindrical section 210. In practical applications, the reinforcing body 1 is arranged around the outer periphery of the front cylindrical section 210 with its inner sidewall inclined from back to front, so that the inner periphery of the reinforcing body 1 can completely fit the outer periphery of the front cylindrical section 210.

[0049] Furthermore, the outer sidewall of the reinforcing body 1 intersects with any plane extending along its axial direction, and this intersecting line extends along the axial direction of the reinforcing body 1. This facilitates the adaptation to the shape of the top surface of the support seat, allowing the outer sidewall of the reinforcing body 1 to fit completely against the top surface of the support seat. Since the inner sidewall of the reinforcing body 1 can fit completely against the outer periphery of the front cylinder section 210, the design of the reinforcing body 1 can eliminate the gap between the front cylinder section 210 and the top surface of the support seat, thereby improving the support stability and strength of the front cylinder section 210.

[0050] The inner circumferential opening of the reinforcing body 1, i.e., the cross-section of the reinforcing body 1 is U-shaped, effectively resists bending stress and provides bidirectional torsional resistance, significantly enhancing the overall stability of the reinforcing body 1. Specifically, the two axial ends of the reinforcing body 1 are a first end 13 and a second end 14, with the first end 13 protruding inward from the second end 14. In practical applications, the reinforcing structure 100 is arranged around the outside of the front cylindrical section 210 with the first end 13 in front and the second end 14 behind, to adapt to the shape of the front cylindrical section 210.

[0051] In this embodiment, the reinforcing body 1 includes a body part 11 and two reinforcing parts 12.

[0052] The outer wall of the body portion 11 is used to fit and fix it to the top surface of the support base. The body portion 11 is cylindrical and has an intersection line with any plane extending along its axial direction.

[0053] Two reinforcing portions 12 are located at the two axial ends of the inner circumference of the main body portion 11, with one reinforcing portion 12 protruding inward from the other reinforcing portion 12. That is, one reinforcing portion 12 is located inside the first end 13 of the main body portion 11, and the other reinforcing portion 12 is located inside the second end 14 of the main body portion 11. Each reinforcing portion 12 is arranged circumferentially along the main body portion 11 and is annular in shape, with the center of the reinforcing portion 12 located on the axis of the main body portion 11.

[0054] Specifically, one of the reinforcing parts 12 has a dimension range of less than or equal to 55 mm in the inward and outward directions, and the other reinforcing part 12 has a dimension range of less than or equal to 60 mm in the inward and outward directions.

[0055] The two reinforcing parts 12 are parallel and each reinforcing part 12 is perpendicular to the main body part 11. This can disperse the stress at the connection between the reinforcing body 1 and the front cylinder section 210 in two perpendicular directions, reduce the stress concentration at the connection, provide bidirectional torsional resistance, effectively resist bending stress, and significantly enhance overall stability.

[0056] Optionally, each reinforcing part 12 and the main body part 11 are connected by a rounded transition. This design can effectively disperse the local stress at the connection between the reinforcing part 12 and the main body part 11, avoid stress concentration caused by sharp corners, and significantly improve the fatigue life of the structure. In addition, too many rounded arcs can make the stress flow lines smoother and avoid the initiation of microcracks caused by stress abrupt changes.

[0057] The two reinforcing parts 12 and the main body part 11 are integrally bent and formed, which makes the reinforcing body 1 have high structural strength and easy to manufacture.

[0058] In this embodiment, the inner circumferential side of the reinforcing body 1 is provided with a bent portion 2 at at least one end along the axial direction. The inner circumferential side of the bent portion 2 is used to fit and fix to the outer circumference of the front cylindrical section 210 of the tank body 200. The provision of the bent portion 2 enhances the structural strength of the reinforcing structure 100, increases the contact area and connection area between the reinforcing structure 100 and the outer circumference of the front cylindrical section 210, thereby improving the connection strength between the reinforcing structure 100 and the front cylindrical section 210. Furthermore, after the reinforcing structure 100 is fixed to the top surface of the support base, the above design can also improve the support stability of the front cylindrical section 210.

[0059] In this embodiment, both ends of the reinforcing body 1 are provided with bent portions 2. That is, both the first end 13 and the second end 14 of the reinforcing body 1 are provided with bent portions 2. Specifically, the two bent portions 2 are provided in a one-to-one correspondence with the two reinforcing portions 12, and the bent portions 2 are correspondingly provided on the inner side of the reinforcing portions 12 and protrude outward from the reinforcing portions 12 along the axial direction.

[0060] The cross-section of the bent portion 2 is circular. Specifically, the bent portion 2 located at the first end 13 of the reinforcing body 1 is inclined inwards in a direction away from the reinforcing body 1, and the bent portion 2 located at the second end 14 is inclined outwards in a direction away from the reinforcing body 1. Furthermore, the two bent portions 2 are arranged collinearly. In practical applications, since the reinforcing body 1 is positioned with the first end 13 in front and the second end 14 behind on the outer periphery of the front cylindrical section 210, the above design facilitates the adaptation of the two bent portions 2 to the shape of the front cylindrical section 210, ensuring that the inner walls of both bent portions 2 can completely conform to the outer periphery of the front cylindrical section 210.

[0061] Figure 9 This is a cross-sectional view of the reinforcing structure 100 in some modified embodiments. Figure 10 This is a cross-sectional view of the reinforcing structure 100 in some other modified embodiments.

[0062] exist Figure 9 , Figure 10 In the embodiment shown, the first end 13 or the second end 14 of the reinforcing body 1 is provided with a bending portion 2.

[0063] refer to Figures 2-4 , Figure 9 , Figure 10 The curved section 2 and the reinforcing section 12 are connected by a rounded arc. This design can effectively disperse the local stress at the connection between the reinforcing section 12 and the curved section 2, avoid stress concentration caused by sharp corners, and significantly improve the fatigue life of the structure. In addition, the rounded arc can make the stress flow line smoother and avoid the initiation of microcracks caused by stress abrupt changes.

[0064] The bending part 2 and the reinforcing part 12 are integrally formed. Since the reinforcing part 12 and the main body part 11 are integrally formed, that is, the reinforcing structure 100 is integrally bent from a single plate, the reinforcing structure 100 has high structural strength and is easy to manufacture.

[0065] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this application, the inner wall of the reinforcing body is inclined inward from one end to the other along the axial direction. That is, the diameter of the shape formed by the inner peripheral wall of the reinforcing body gradually decreases. This makes it easier for the inner peripheral side of the reinforcing body to adapt to the shape of the front cylinder section, thereby eliminating the gap between the reinforcing body and the front cylinder section. This facilitates the complete fit and fixation of the inner peripheral side of the reinforcing body to the outer peripheral side of the front cylinder section, increasing the contact area and connection area between the reinforcing body and the front cylinder section. At the same time, since the inner peripheral side of the reinforcing body has a bent portion at least at one end along the axial direction, and the bent portion is used to fit and fix to the outer peripheral side of the front cylinder section, the setting of the bent portion strengthens the structural strength of the reinforcing structure, increases the contact area and connection area between the reinforcing structure and the outer peripheral side of the front cylinder section, thereby improving the connection strength between the reinforcing structure and the front cylinder section. Moreover, after the reinforcing structure is fixed to the top surface of the support seat of the tank truck, the above design can also improve the support stability of the front cylinder section.

[0066] Furthermore, the outer wall of the reinforcing body intersects with any plane extending along its axial direction, and this intersection line extends along the axial direction of the reinforcing body. This facilitates the adaptation to the shape of the top surface of the tank truck's support seat, allowing the outer wall of the reinforcing body to fit completely against the top surface of the support seat. Since the inner wall of the reinforcing body can fit completely against the outer periphery of the front cylinder section, that is, the design of the inner and outer walls of the reinforcing body can help eliminate the gap between the front cylinder section and the top surface of the support seat, thereby improving the support stability and strength of the front cylinder section.

[0067] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
