The specific embodiment
In order to further illustrate principle of the present invention and structure, existing by reference to the accompanying drawings to a preferred embodiment of the present invention will be described in detail.
Refer to Fig. 1, Fig. 1 is tank container front view of the present invention.Tank container of the present invention comprises framework 1, be arranged at tank body 2 in described framework and the supporting construction 3 for fixing tank body 2 and framework 1, described supporting construction 3 is along the longitudinal direction setting of described tank body 1 the front end frame 11 of connecting frame 1 and back-end box 12, wherein, the width of described framework 1 is 2501mm ~ 2550mm.
Described framework 1 is the rectangular box being formed by connecting by corner fittings 6 by front end frame 11, back-end box 12 and curb girder 13, holds the tank body 2 suitable with its size therein.In the time of the width widen of described framework 1, the diameter of described tank body 2 can suitably strengthen, and to maximize the volume of tank body 2, and then improves tank packing list time transportation cargo capacity, reduces traffic cost.
Tank body 2 entirety is cylindrical, can splendid attire in it poisonous, nontoxic, corrosion, free from corrosion gaseous state, hydraulic cargo or solid-state granular goods.
In the periphery of described tank body 2, along multiple reinforcing pads 5 are set on the length direction of tank body 2, for strengthening the intensity of described tank body 2, better to resist external pressure.Described reinforcing pad 5 disconnects at the position of center line place of the side of described tank body 2, makes it not exceed the scope of framework 1.
At the each welding in the two ends of described tank body 2 one clamping ring 4, described clamping ring 4 is welded on described framework 1, and tank body 2 and framework 1 are connected and fixed.
Near zone in the close bottom of described tank body 2 sides is provided with a supporting construction 3, described supporting construction 3 is for strengthening being connected and fixed of tank body 2 and framework 1, even to guarantee that framework 1 is widened, tank body 2 volumes become in large situation, still can firmly be connected between tank body 2 and framework 1.
Described supporting construction 3 comprises along the rectangular connection structure 31 of described tank body 1 length direction setting and connects described connection structure 31 and front end frame 11(or back-end box 12) pillar 32.Wherein, described connection structure 31 is sectional material connection structure.The two ends of described connection structure 31 are welded on the side of described tank body 1 by backing plate 33.Described pillar 32 becomes a leaning angle with the longitudinal vertical plane of crossing tank body 2 centers, for example, miter angle, the front end frame 11(of its one end and framework 1 or back-end box 12) weld together, its other end is by backing plate 33 and connection structure 31 weld togethers.
As shown in Figure 2 a, its front end frame one embodiment schematic diagram that is tank container frame of the present invention.Front end frame 11 comprises head piece 111, is parallel to head piece 111 bottom cross beams 112, connects left longeron 113 and the right vertical beam 114 of head piece 111 and bottom cross beam 112, and wherein, top, bottom cross beam 111,112 and left and right longeron are all connected and fixed by large corner fittings 61.
As shown in Figure 2 b, its back-end box one embodiment schematic diagram that is tank container frame of the present invention.Back-end box 12 is identical with the structure of front end frame 11, is not just repeating one by one at this.But for tank body 2, the ladder 22 that the end of the tank body 2 corresponding with back-end box 12 is provided with liquid valve 21 and leads to top from tank body 2 bottoms for people.
Wherein, head piece 111 and the large corner fittings 61 overall length W in its two ends are 2501mm ~ 2550mm.Although the width of ISO freight container Shipping is defined as 2438mm, if but tank container of the present invention does not participate in Shipping, only for highway, railway transportation, can suitably the width of framework 1 be lengthened, thereby the diameter of tank body 2 is lengthened, make in meeting transportation request, expand as much as possible volume, improve tank packing list time transportation cargo capacity, reduce traffic cost.
Widening on the basis of framework 1 width, the volume of tank body 1 is extended, and maximum volume can reach 28.3 cubic meters.
In addition, for example, in the case of guaranteeing that the distance L (2260 mm, 2259mm) between left and right longeron 113,114 both sides corner fittings centre holes meets standard handling requirement, can select dissimilar corner fittings to connect left and right longeron 113,114, for example, as shown in Figure 3 a and Figure 3 b shows, the equal selection standard corner fittings 62 in two ends of head piece 111 and bottom cross beam 112 is connected left and right longeron 113,114, wherein, in the time that left and right longeron 113,114 is connected with standard corner fitting 62, pruned a part and be wedge shape in its one end near standard corner fitting 62; Again for example, as shown in Fig. 4 a and Fig. 4 b, head piece 111 two ends selection standard corner fittings 62 connect left and right longeron 113,114, and bottom cross beam 112 two ends select large corner fittings 61 to connect left and right longeron 113,114; Certainly, also can be, head piece two ends select large corner fittings to connect left and right longeron, bottom cross beam two ends selection standard corner fittings connects left and right longeron (not shown), in a word, in the case of guaranteeing that distance L between left and right longeron 113,114 both sides corner fittings centre holes meets standard handling requires, can select dissimilar corner fittings to connect, make the length of frame width reach required size 2501mm ~ 2550mm.Wherein, frame width can be arbitrary value between 2501mm and 2550mm, as 2502mm, and 2503mm etc.
Preferably, the width of framework 1 is 2510mm.
Preferably, the width of framework 1 is 2520mm.
Preferably, the width of framework 1 is 2530mm.
In sum, tank container of the present invention expands the volume of tank body by lengthening the width of framework, in the situation that meeting transportation request, improves tank packing list time transportation cargo capacity, reduces traffic cost.
The foregoing is only better possible embodiments of the present invention, not limit the scope of the invention.Every equivalent structure or conversion of equivalent flow process that utilizes specification sheets of the present invention and accompanying drawing content to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
