Abstract
The utility model relates to a rear support structure of a horizontal type low-temperature gas cylinder. The rear support structure is arranged between an inner container rear end socket and a shell rear end socket of the gas cylinder and comprises a supporting shaft which passes through a center hole of the inner container rear end socket, and one end of the supporting shaft stretches into the inner container rear end socket and is fixed on an inner supporting ring of the inner container rear end socket; a supporting frame is arranged on the inner side of the shell rear end socket and consists of a fixed lateral supporting plate and a fixed longitudinal supporting plate; the left end and the right end of the lateral supporting plate are respectively provided with an arc gap; the junction of the lateral supporting plate and the longitudinal supporting plate is provided with a fixed ring coaxial with a center hole of the inner container rear end socket, and the other end of the supporting shaft is inserted into the fixed ring. The rear support structure provided by the utility model has the advantages that the supporting intensity is improved, and the heat transfer is effectively reduced, so that the whole property of a product is improved, and the transport efficiency of low-temperature liquid is improved.
Description
Technical field
The utility model relates to a kind of supporting structure, the back support structure of a kind of horizontal low temperature gas cylinder of concrete finger.
Background technique
Automobile is used for the supply of car liquefied petroleum gas fuel with liquefied natural gas bottle.Known automobile is equipped with the double layer construction that comprises inner bag and shell with liquefied natural gas bottle, there is winding layer the inner bag outside, and vacuumizes between inner bag and the shell; Connect by supporting structure between the rear head of inner bag and shell and inner bag is fixed in the shell.Because this supporting structure will be born certain external force and oscillating load in transportation and using process, so require supporting structure not only to have enough intensity, also should have enough rigidity and fatigue resistance; In addition, because the interior loading of inner bag is cryogenic liquide, the evaporation loss that causes for reducing heat transmission also requires supporting structure must possess the little performance of conducting heat.
At present, mostly this supporting structure is to adopt the dunnage of two intersections to form with the back shaft that is connected inside and outside cylindrical shell.Though this supporting structure can guarantee support stiffness and less heat transfer, rigidity is relatively poor, and in actual use, the risk of fatigue failure may appear in supporting frame under the alternate load effect.
Therefore, need to improve automobile with the inner bag rear support structure of liquefied natural gas bottle, with further raising support stiffness and fatigue resistance, guarantee gas cylinder reliability in use.
Summary of the invention
The purpose of this utility model is exactly the back support structure that a kind of horizontal low temperature gas cylinder will be provided, and to improve support strength, reduces the heat transmission, thereby improves the overall performance of product, improves the conveying efficiency of cryogenic liquide.
For achieving the above object, the back support structure of the horizontal low temperature gas cylinder that the utility model is designed, be arranged between the inner bag rear head and shell rear head of this gas cylinder, it is characterized in that: it comprises back shaft, described back shaft passes the center hole of inner bag rear head, and described back shaft one end stretches in the inner bag rear head and is fixed on the inner bag rear head medial branch pushing out ring; Described shell rear head inboard is provided with supporting frame, support frame as described above is made of fixing cross-brace plate and longitudinal supporting plate, two ends, the described cross-brace plate left and right sides are respectively equipped with arc notch, described cross-brace plate and longitudinal supporting plate intersection are provided with the retaining ring coaxial with the center hole of inner bag rear head, and the described back shaft the other end is inserted in the retaining ring.
Further, described longitudinal supporting plate is the sheet metal with U-shaped flanging, is in order to increase the rigidity of dunnage.
Further, two ends, the described cross-brace plate left and right sides respectively are provided with two arc notch, and two arc notch of every end are arranged symmetrically with up and down, and design is in order to reduce heat transfer area like this.
The utility model has the advantage of: the cross-brace plate is designed with arc notch, has reduced heat transfer area; Longitudinal supporting plate adopts the sheet metal of U-shaped flanging, in the situation that guaranteed the constant rigidity that increases dunnage of minimum sectional area.This supporting structure in the situation that guarantee to conduct heat does not increase, can not only Effective Raise support stiffness and fatigue resistance, can also improve gas cylinder reliability in use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1 housing rear head.
Among the figure: inner bag rear head 1(wherein, center hole B), support ring 2, back shaft 3, shell rear head 4, cross-brace plate 5, retaining ring 6, longitudinal supporting plate 7, supporting frame 8, arc notch 9.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The back support structure of the horizontal low temperature gas cylinder shown in the figure, be arranged between the inner bag rear head 1 and shell rear head 4 of this gas cylinder, it comprises back shaft 3, back shaft 3 passes the hole B at inner bag rear head 1 center, the one end stretches into inner bag rear head 1, and is fixed on the inner bag rear head 1 medial branch pushing out ring 2; Shell rear head 4 inboards are provided with supporting frame 8, supporting frame 8 is made of fixing cross-brace plate 5 and longitudinal supporting plate 7, two ends, cross-brace plate 5 left and right sides respectively are provided with two arc notch 9, two arc notch 9 of every end are arranged symmetrically with up and down, longitudinal supporting plate 7 is the sheet metal of U-shaped flanging, cross-brace plate 5 and longitudinal supporting plate 7 intersections are provided with the retaining ring 6 coaxial with the hole B at inner bag rear head 1 center, and back shaft 3 the other ends are inserted in the retaining ring 6.
The utility model adopts the girth plate mode that combines, and longitudinal supporting plate 7 adopts band flanging sheet metals to make, and can play effective supporting effect to inner bag.Gas cylinder bears the oscillating load of Vertical direction usually under actual conditions, compared with prior art, with the longitudinal supporting plate 7 of flanging in the situation that the constant rigidity that increases dunnage of proof strength and heat transfer area, can prevent effectively that dunnage lost efficacy because of oscillating load, improve gas cylinder reliability in use.
