Abstract
The utility model relates to a rear end supporting structure for a gas bottle of automobile liquefied natural gas. The utility model provides the rear end supporting structure for the gas bottle of the automobile liquefied natural gas, and the rear end supporting structure can be used for effectively reducing heat leakage. The rear end supporting structure comprises an inner rear end socket, an outer rear end socket, a supporting shaft, a supporting pipe cap, a supporting shaft sleeve and a vertical supporting plate, wherein the supporting pipe cap is in welded connection with the inner rear end socket and the supporting shaft; the vertical supporting plate is in the welded connection with the outer rear end socket; the rear end supporting structure further comprises a first sleeve ring and a second sleeve ring; a lug boss is formed at the bottom of the supporting shaft sleeve; the outer wall of the supporting shaft sleeve is sleeved with the first sleeve ring and the first sleeve ring is abutted against the lug boss; the outer wall of the first sleeve ring is sleeved with the second sleeve ring and the second sleeve ring is connected with the vertical supporting plate. Preferably, connection holes are formed in the outer walls of the supporting shaft sleeve, the first sleeve ring and the second sleeve ring; a bolt penetrates through the connection holes so as to connect the supporting shaft sleeve, the first sleeve ring and the second sleeve ring together.
Description
Technical field
The utility model relates to a kind of supporting structure, particularly a kind of Vehicular liquefied natural gas cylinder rear end supporting structure.
Background technique
Existing Vehicular liquefied natural gas cylinder comprises inner bag and outer courage, and front end support device and rear end support device between inner-outer tube two ends, plays and connects and the effect of heat conduction.Conventionally, this liquefied natural gas bottle rear end supporting structure is made up of interior rear head, outer rear head, support pipe cap, back shaft, support sleeve and longitudinal supporting plate, and support sleeve is directly connected with longitudinal supporting plate.Because all component materials of supporting structure are stainless steel, thermal conductivity is large, hot gas is directly flowed through after support sleeve, back shaft and is delivered to support device inside via longitudinal supporting plate, the thermal resistance of this kind of structure is little, thereby make the leakage heat of Vehicular liquefied natural gas cylinder larger, cause static evaporation rate large, and static evaporation rate is an important operation parameter of Vehicular liquefied natural gas cylinder, the technology content of cryogenic insulated cylinder is often embodied in this index, is the concentrated expression of project organization, vaccum thermal insulation technique.
Model utility content
For deficiency of the prior art, the utility model provides a kind of can effectively reduce the Vehicular liquefied natural gas cylinder rear end supporting structure of leaking heat.
In order to address the above problem, this kind of Vehicular liquefied natural gas cylinder rear end supporting structure, comprise: interior rear head, outer rear head, back shaft, support pipe cap, support sleeve, longitudinal supporting plate, supporting pipe cap and interior rear head and back shaft is welded to connect, longitudinal supporting plate and outer rear head are welded to connect, also comprise first collar and second collar, the bottom of described support sleeve is formed with boss, and this first set ring set is located on the outer wall of support sleeve and offsets with boss; This second collar is set on the outer wall of first collar and is connected with longitudinal supporting plate.
Preferably, on the outer wall of described support sleeve, first collar and second collar, be respectively equipped with attachment hole, bolt links together support sleeve, first collar and second collar through this attachment hole.
Preferably, Spielpassung between described support sleeve and back shaft; Described support sleeve, second collar are stainless steel, and described first collar is fiber glass epoxy.The outer wall of described support pipe cap is provided with topping up through hole.
The beneficial effects of the utility model are: because the first collar material is fiber glass epoxy, thermal conductivity is little, thereby raising thermal resistance, between support sleeve and second collar, increase the thermal resistance that first collar can improve rear end support conduction process, thereby effectively reduce the leakage heat of Vehicular liquefied natural gas cylinder, reduce the static evaporation rate of gas cylinder.
Brief description of the drawings
