Abstract

The utility model discloses a liquefied gas tank truck with an annular V-shaped reinforced structure, belonging to the technical field of carrying equipment. The improved key points of the common liquefied gas tank truck with the structure of an annular reinforced ring are as follows: the common structure of the annular reinforced ring is improved into the annular V-shaped structure, namely a V-shaped structure is connected in an annular ring; and two endpoints and one top points of the V-shaped structure are arranged on the annular ring. Compared with the annular reinforced ring, the annular V-shaped reinforced structure has the following beneficial effects: under the premise that the requirements of strength and stability are met, after the annular V-shaped reinforced structure is adopted, the total weight and volume of the reinforced structure are obviously reduced; therefore, the carrying capacity of the tank truck is improved.

Description

A kind of annulus V-arrangement reinforced structure Liquefied gas tanker

Technical field

The utility model relates to Liquefied gas tanker, relates in particular to annulus V-arrangement reinforced structure Liquefied gas tanker, under the prerequisite of proof strength and stability requirement, has reduced material, has reduced manufacture cost, has improved the tank car bearing capacity, belongs to the vehicle equipment technical field.

Background technique

Liquefied gas tanker is the main vehicle equipment of the present liquid gas of China; Because liquid gas is often inflammable and explosive; And tank car bears unsettled loading in transportation process, guarantee transportation safety, and tank car must strictness satisfy demand of technical standard in design, manufacture process.The global design of tank car at present can be carried out according to pressurized container conventional design standard GB150-1998 " GB150-1998 ", perhaps adopts Finite Element Method that tank car is carried out stress analysis, carries out strength check according to relevant criterion again.LPG tank truck in use bears loadings such as interior pressure, gravity, inertial force, also possibly bear the external pressure effect sometimes, and therefore, operated by rotary motion has stiffening ring on the tank body.

The common ring stiffening ring of the many employings of Liquefied gas tanker at present; At this moment; Liquefied gas tanker often can not satisfy the requirement of strength in the relevant criterion under the load working condition effect that side direction or inertial force participation are downwards arranged, if the simple stiffening ring thickness that increases; Not only manufacture cost improves, and the more important thing is that weight increases.For the certain tank car of carrying capacity, the increase of weight of equipment means the minimizing of splendid attire medium, so increasing thickness solution strength problem merely is not to be good way.In fact, because transportation inertial load and medium-weight load are to act on the specific direction, the ring stiffening ring structurally is not very appropriate.

The model utility content

The purpose of the utility model is to the existing problem of Liquefied gas tanker that adopts at present common ring stiffening ring structure, and a kind of Liquefied gas tanker of new stiffening ring structure is provided.

The utility model annulus V-arrangement reinforced structure Liquefied gas tanker is the improvement to common ring stiffening ring structure Liquefied gas tanker; Improved key is; With common ring stiffening ring architecture advances is annulus " V " shape structure, that is annulus V-arrangement reinforced structure shown in Figure 1.

The utility model Liquefied gas tanker comprises: be placed in the cylindrical shell 2 on the V-type bearing 10; Cylindrical shell 2 two ends are connected with end socket 1 and 8, and relief valve port 3, manhole 6 are arranged at cylindrical shell 2 tops, and gas phase mouth 13, liquid phase mouth 14, thermometer mouth 15 and sewage draining exit 12 are arranged at cylindrical shell 2 bottoms; The level meter mouth 9 at end socket center; Swash plate 7, stiffening ring 5 and the fixing dunnage 4 of gas phase pipe are arranged in the cylindrical shell 2, it is characterized in that described stiffening ring is annulus " V " shape structure stiffening ring; Promptly consubstantiality is connected with " V " shape structure in the annulus circle, and two end points of " V " shape structure and a summit are all on the annulus circle.The summit angle of " V " shape structure is 90-150 °.The thickness of " V " shape thickness of structure and annulus can be identical, also can be different.

Compare with the ring stiffening ring, under the prerequisite that satisfies intensity and stability requirement, behind the employing annulus V-arrangement reinforced structure, the gross weight and the volume of reinforced structure obviously descend, and have therefore also just improved the bearing capacity of tank car.

Embodiment:

With embodiment the utility model is further specified below.But the utility model is not limited to following examples.

As shown in Figures 2 and 3, the present embodiment Liquefied gas tanker comprises: be placed in the cylindrical shell 2 on the V-type bearing 10, adopt the V-type bearing can reduce the height of C.G. of cylindrical shell than common saddle support; Cylindrical shell 2 two ends are connected with dome head 1 and ellipse head 8; Cylindrical shell 2 is provided with relief valve port 3 and (is arranged on the cylindrical shell top front; When the jar internal pressure increases suddenly, open be installed in relief valve port the safety valve exhaust in order to avoid the tank body blast), (inlet is arranged on the cylindrical shell bottom, in jar, rises to the tank body top with the form of long tube, is used for discharging and is written into gas for manhole 6 (be arranged on rear, cylindrical shell top and pass in and out the check tank interior in order to make things convenient for personnel), gas phase mouth 13; At tank deck; Fixing with dunnage 4), liquid phase mouth 14 (be arranged on the cylindrical shell bottom, be used for discharging and be written into liquid), thermometer mouth 15 (be arranged on the cylindrical shell bottom, be used to insert the thermometer that has thermometer boss 11 with a medium temperature in measuring jar), level meter mouth 9 (be arranged on the center of ellipse head; Be used to place level meter; The liquid level of observation jar interior medium), sewage draining exit 12 a plurality of interfaces such as (are arranged on tank base, in the middle of the V-arrangement bearing, are used for the dirt of deposition in the drain tank); Swash plate 7 is housed in the cylindrical shell 2 (to be evenly distributed in the jar along the tank body axial direction; Rocking of medium produced barrier effect) and stiffening ring 5 (arrange 3 along the tank body axial direction, improve the ability of tank body opposing external pressure, and under the inertial force effect, improve tank intensity).In addition, the stiffening ring 5 on the tank body adopts annulus V-arrangement reinforced structure shown in Figure 1, and " V " shape structure summit angle is 120 °.

In the present embodiment, former stiffening ring volume is about 0.111m ³, need 42mm thickness could satisfy requirement of strength, improve back reinforced structure volume and be about 0.0626m ³, desired thickness is 22mm, calculates thus, improves the back reinforced structure and can save material 43.9%.Under the prerequisite of proof strength and stability requirement, reduced material, reduced manufacture cost, improved the tank car bearing capacity.
