Description
Technical field
This utility model is related to a kind of tank container frame, in particular for shipping the pot type of liquefied natural gas (LNG)
Container framework, the framework can make tank container pass through railway, highway, water-borne transport LNG.
Background technology
LNG tank formula container quickly grows in recent years, is especially adapted for use in the LNG tank formula container of railway transportation.In order to
Tank container is enable to bear larger railway impact of collision load, or existing railway LNG tank formula container framework knot
Structure is complicated, local stress is high, from great；Though stress is good, structure design is unfavorable for that tank container adds the conjunction of heat-extraction system
Removing the work is put.
Fig. 1～Fig. 5 is a kind of existing railway LNG tank formula container frame structure, its mainly by tank body 1a, skirt 2a,
The compositions such as longeron composition 3a, end frame 4a, longeron backing plate 5a.Skirt 2a one end passes through casing 21a, rear shrouding 22a and tank body 1a is welded
Connect in succession, the other end is welded to connect with end frame 4a.Longeron constitutes 3a one end by symmetrical one group of longeron 32a and longeron pad
Plate 5a, tank body 1a are integrally welded, two base angles of the other end by symmetrical one group of raker beam 31a respectively with end frame 4a
Part group is welded, and longeron 32a is linked into an integrated entity by a bolster 33a.End frame 4a by corner fittings 41a, upper diagonal brace 42a, column 43a,
Top end transverse member 44a and bottom end rail 45a compositions.The advantage of the frame structure is that skirt 2a also serves as valve box, and its structure space is spacious,
Tank case is conducive to add the reasonable Arrangement of heat-extraction system.The shortcoming of presence mainly has：First, the longitudinal impact force that container bears is main
The bottom of end frame 4a is concentrated on, then shrouding 22a is skirt 2a bottoms to be linked into an integrated entity with tank body 1a by angle welding.Pot type
Container is born larger shear stress and bending stress, the longitudinal direction that container end frame 4a bears by impact of collision hour angle commissure
Impulsive force can not be transferred to tank body 1a by skirt 2a well.Second, the longitudinal force that tank container bears need to be led to successively
Cross the bottom corner piece of end frame 4a, raker beam 31a, longeron 32a, longeron backing plate 5a and can just be transferred to tank body 1a, the bang path of power is multiple
It is miscellaneous changeable, frame structure many places stress concentration.When longitudinal force is larger, the corner of raker beam 31a can also be larger attached because bearing
Plus moment of flexure and the even fracture that occurs bending and deformation, cause longeron composition 3a to weaken or lose the effect of transmission longitudinal force.3rd, frame
Frame complex structure, conducts oneself with dignity larger.
Fig. 6～Figure 10 is existing another kind of railway LNG tank formula container frame structure, and which is mainly by tank body 1b, skirt
The compositions such as 2b, longeron composition 3b, end frame 4b, longeron backing plate 5b.Skirt 2b is straight tubular construction, the external diameter phase of external diameter and tank body 1b
Together, its one end is welded to connect with tank body 1b, and the other end is welded to connect with end frame 4b.Longeron backing plate 5b is welded on tank body 1b and skirt
The bottom of 2b.Longeron composition 3b is made up of raker beam 31b, longeron 32b and bolster 33b, one end and the end frame 4b welderings of longeron 32b
One is connected into, two stiles are integrally welded with longeron backing plate 5b.Symmetrical one group of raker beam 31b one end respectively with end frame 4b
The welding of left and right bottom corner piece, the other end welded with longeron 32b.End frame 4b is by corner fittings 41b, upper diagonal brace 42b, column 43b, top end transverse member
44b, bottom end rail 45b and lower diagonal brace 46b compositions.The advantage of the frame structure is：First, skirt 2b simple structures, its section
Shape is consistent with tank body 1b, and the two junction will not form larger stress concentration.Secondth, the longitudinal force for holding frame 4b to bear
Tank body 1b can be transferred to by a plurality of approach is homodisperse, and every bang path is simple, direct.The shortcoming of presence is main
It is：LNG tank case adds the pipeline of heat-extraction system, valve, supports more, and main centralized arrangement, in valve lower box part, skirt 2b is also served as
Because its structure space is narrow and small and bottom out-of-flatness during valve box, cause plus heat-extraction system is difficult to accomplish reasonable Arrangement.
The design of above two LNG railway tank case frame structure comes with some shortcomings, it is impossible to while it is larger to take into account carrying
Longitudinal impact force and reasonable Arrangement add heat-extraction system.
Utility model content
Larger longitudinal impact force can not be carried and reasonable Arrangement adds row system while taking into account to solve available frame structure
The technical problem of system, the technical problems to be solved in the utility model are to provide one kind and can meet railway transportation operating mode, can make again
Plus the pipeline in heat-extraction system, valve, support etc. obtain the LNG tank formula container skirt and framework of reasonable Arrangement.
This utility model solves the technical scheme that adopted of above-mentioned technical problem：
Shrouding after tank container skirt provided by the utility model, including casing and two, which is characterized in that：
The casing includes top straight tube arc section, bottom straight tube arc section, the first linkage section and the second linkage section, the top straight tube
One end of arc section is connected with one end of bottom straight tube arc section by the first linkage section, the top straight tube arc section it is another
End is connected with the other end of bottom straight tube arc section by the second linkage section；
First linkage section and the second linkage section along the direction of top straight tube arc section to bottom straight tube arc section according to
It is secondary including vertical section, changeover portion and horizontal segment；
The external diameter of the top straight tube arc section and bottom straight tube arc section is identical with tank body external diameter.
It is basic structure of the present utility model above, based on the basic structure, this utility model also makes following optimization limit
