Description

Tank container and frame structure thereof

Technical field

The present invention relates to a tank container, and more particularly to a tank container having a novel frame structure. Background technique

A tank container for transporting liquids has been commonly used. Figure 1 shows a prior art tank container 1 in which the tank body 2 and the frame 3 are joined by a skirt 4, while the two ends of the frame 3 pass between the two upper side rails 5 and the two lower side beams. 6 to connect. This prior art tank container 1 requires the addition of reinforcing beams 7 to the end frame 3 and the lower side rail 6, and a plurality of reinforcing beams 8 and 9 are provided on each of the end frames 3 to ensure the rigidity of the casing.

Therefore, the frame structure of the prior art tank container is relatively complicated and its own weight is relatively heavy. Moreover, when the conventional frame structure tank container has special requirements, such as loading plastic pellets, it is necessary to disconnect the end frame bottom beam because it needs to be discharged from the head end. Therefore, it is necessary to add some auxiliary support to meet the strength of the frame. Requirements, but this leads to a more complex framework structure and increased self-weight. Summary of the invention

The technical problem to be solved by the present invention is to provide a tank container having a good mechanical property, a simple structure and a light weight, and a frame structure thereof.

In order to achieve the above object, the present invention provides a tank container including a tank body and a first end frame and a second end frame disposed at right and left ends of the tank body, the tank body including a cylinder body and a connection provided with a reinforcing ring The first head and the second head at the two ends of the barrel, wherein the first end frame and the second end frame are respectively connected to the can body through a plurality of single plates.

Preferably, the plurality of single boards are respectively disposed on the four corners of the first end frame and the second end frame. Preferably, the single board disposed on the corner of the first end frame is connected to the first head and further extends to the barrel; the single board connection disposed on the corner of the second end frame To the second head and further to the barrel.

Preferably, the single board has a flange. And, the veneer and the can body are connected together through a slot structure. The channel-shaped structural member is further forwardly attached to the reinforcing ring position of the can body.

Preferably, the first end frame and the second end frame are respectively provided with a plurality of end diagonal braces, which are connected to the On the first head and the second head. The end braces are disposed at four corners of each end frame and are disposed along a diagonal of the first end frame and the second end frame. Further, the end braces are inclined at an angle inward. Moreover, the end gusset is connected with the first head or the second head, and a reinforcing plate is arranged to avoid the problem of sharp corner fatigue.

In order to achieve the above object, the present invention also provides a frame structure for supporting a can body of a can container, comprising: a first end frame and a second end frame disposed at two ends of the can body, wherein The first and second end frames are provided with a plurality of veneers connected to the can body.

Preferably, the single boards are respectively disposed on the four corners of the first end frame and the second end frame. Preferably, the veneer has a hem. And the veneer and the can body are connected by a slot structure.

Preferably, the first end frame and the second end frame are respectively provided with four end supports connected to the can body along the diagonal direction thereof. The end braces are angled inwardly to accommodate tanks of different lengths and diameters. A reinforcing plate is disposed at the joint of the end bracing and the can body to avoid the problem of sharp corner fatigue. The end bracing is a steel piece or a thick-walled flat steel piece.

According to an aspect of the invention, the present invention uses eight veneers with hem to join the end frame to the sleek body, so that the entire tank has better mechanical properties and can be applied to various liquid stainless steel tanks, Three types of pressure vessels are liquefied gas tanks, powdered cargo tanks, etc.

According to another aspect of the invention, the can container of the present invention can also meet the need for greater strength by further incorporating the end braces on the end frame. For example, the tank container of the present invention can be applied to some tanks having special requirements, such as tanks for carrying plastic pellets, in the case where the end frame bottom beam is broken to facilitate discharge from the head end, the present invention is employed. The frame structure of the tank container is not affected by the disconnection of the end frame bottom beam. For those large-capacity tanks, for example, designed with a total weight of 45 tons (international standard, including 40 tons and 5 tons of dead weight), the frame structure of the present invention can still meet the strength requirements.

The invention is described in detail below with reference to the accompanying drawings and specific embodiments. DRAWINGS

As shown in Fig. 2, the can container 100 of the present invention includes a can body 10 and a first end frame 20 and a second end frame 30 disposed at both ends of the can body 10. The can body 10 is formed by sealingly connecting the intermediate cylinder 11 and the first head 12 and the second head 13 at both ends. On the outer surface of the can body 10, reinforcing rings 14, 15 are provided outside the cylindrical body 11. Of course, the reinforcing rings 14, 15 can also be arranged in the tank. In particular, the frame structure of the present invention is referred to as a "single-plate eight-claw type" frame structure, that is, a single plate 40 is disposed on the four corners of the first end frame 20 and the second end frame 30, Used to connect with the can body 10. Further, the veneers 40 are attached to the first head 12 and the second head 13, respectively, and further extended to the both ends of the barrel 11, thereby stably supporting the can body 10 as a whole. Preferably, the veneer 40 has a hem 41 to enhance the strength of the frame structure.

Moreover, the first end frame 20 and the second end frame 30 are further provided with a plurality of end braces 50 connected to the can body 10. As shown in FIG. 3, taking the first end frame 20 as an example, on the first end frame 20, four end braces 50 are provided on the first end frame 12 in the direction of the diagonal A. These end braces 50 can be steel or thick-walled flat steel.

As shown in Fig. 4, the end braces 50 can also be inclined inwardly by an angle D to accommodate tanks of different lengths and diameters, such that the length tolerance of the can body is not critical. Further, preferably, the present invention transitions when the veneer 40 is joined to the barrel 11, especially for the thin-walled container, and the trough-type structural member 16 is further advanced to the reinforcing ring 14 Location.

As shown in Fig. 5, the structure of the channel-shaped structural member 16 is shown.

As shown in FIG. 6, in combination with FIG. 3, preferably, a U-shaped reinforcing plate 51 is provided at the joint of the end bracing 50 and the head, which can effectively avoid the problem of sharp-angle fatigue and does not affect the inclination. Support and head normal Welding.

The "single-plate eight-claw type" frame structure of the invention not only has good mechanical properties, but also has a simple structure and a light weight. Moreover, for some tank containers with special requirements, such as tank containers carrying plastic pellets that need to be disconnected from the bottom frame of the end frame, the bottom beam can be directly disconnected to meet the strength requirements. Even for large-load tank containers, the strength requirements can be met. Therefore, it has better applicability.

The invention may, of course, be embodied in a variety of other embodiments without departing from the spirit and scope of the invention. Changes and modifications are intended to be included within the scope of the appended claims.
