Description

The big volume tank car of low center of gravity

The utility model relates to the tank car of multiple goods such as can delivering powder, a material class, oils, is meant that especially a kind of axletree is designed to the big volume tank car of 21 tons of weights by national standard.

At present, serial its center of gravity of goods tank car that 21 tons of axles that put into effect on the China railways line are heavy is all higher, about about 2200mm.Trace it to its cause mainly is that tank body is the cylinder horizontal type structure, the cylinder nadir is positioned on the floor underframe for vehicle on the plane, its shortcoming is mainly reflected in: along with the increasing of stowage, the car load center of gravity increases, the vehicle dynamics degradation, can't adapt to railway speed increase, heavily stressed requirement, also fail fully to effectively utilize vehicle gauge with interior space.Existing in the world low center of gravity tank car then is the structure with elongated curb girder, its corresponding increase of conducting oneself with dignity.

The purpose of this utility model is exactly to provide a kind of under the heavy prerequisite of 21 tons of axles of standard, can reduce the big volume tank car of low center of gravity of car load center of gravity significantly.

For realizing this purpose, the big volume tank car of low center of gravity that the utility model is designed, comprise a horizontally-arranged tank body, this tank body unit design is ingot type structure, its middle part is a cylindrical structure, two ends are conical structure, and the Up Highway UHW of this cylindrical structure and conical structure is in the same vertical cross-section, and with longitudinal center's line parallel of cylindrical structure; Angle α=10～15 of the Down Highway of conical structure and horizontal surface °.The cone position of this tank body closely is connected as one by the draw beam extendible portion on pillow pulling device and the little underframe, make the Down Highway of cylindrical structure be lower than plane on the draw beam, car load drops on the bogie truck, becomes the monocoque structure of no central sill, no elongated curb girder.

Advantage of the present utility model is: tank structure is the ingot type, stick up at middle low two, the taper position of its perk links to each other with the draw beam extendible portion, make the Down Highway of intermediate cylindrical body structure be lower than the last plane of draw beam, thereby reduced the center of gravity of car load effectively, make full use of vehicle gauge with interior space increase-volume, improved the dynamic performance of vehicle, more can adapt to railway speed increase, heavily stressed requirement.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is the integral structure scheme drawing of the heavy big volume tank car of low center of gravity of a kind of 21 tons of axles;

Fig. 2 is the tank body contour structures scheme drawing among Fig. 1;

Fig. 3 is the part cross-sectional schematic of tank body shown in Figure 2;

Fig. 4 is the A-A cross-sectional schematic of Fig. 3;

Fig. 5 is tank body and handle frame point of attachment structural representation;

Fig. 6 is the B-B cross-sectional schematic of Fig. 5;

Fig. 7 is annular shaped steel reinforcing rib structure scheme drawing.

The heavy big volume railway of the low center of gravity jar of 21 tons of axles shown in the figure, has a horizontally-arranged tank body 1, tank body 1 combines as a whole by separate pillow pulling device 4a and the handle frame 4b of two covers, car load drops on the bogie truck 49, constitutes the lighter no elongated curb girder of deadweight and the integrated carrying all steel welded structure of central sill.Its special character is: tank body 1 design is ingot type structure.Be that tank body 1 middle part is cylindrical structure 1a, two ends are conical structure 1b.The Up Highway UHW 2a of cylindrical structure 1a and conical structure 1b is in the same vertical cross-section, and parallel with the longitudinal centerline 2b of cylindrical structure 1a.Angle α=10～15 of the Down Highway of conical structure 1b and horizontal surface °, its tapering part links to each other with draw beam extendible portion 4c on the handle frame 4b, this makes the Down Highway 4d of cylindrical structure 1a be lower than plane 4f on the draw beam, thereby reduced the center of gravity of tank car effectively, vehicle's center of gravity can be controlled between 1975～1980mm.

Be provided with a waling plate structure 2c below the inside of above-mentioned tank body 1, the cross-sectional plane of this waling plate 2c is П type 3a, constitutes box girder structure with tank body 1 welding, which is provided with ventilation, draining, oil through.This waling plate 2c plays and tank body 1 common effect of transmitting longitudinal force on the one hand, also can improve the rigidity of tank body 1 on the other hand, improves the intensity of car load.

Between the taper position of above-mentioned tank body 1 and draw beam extendible portion 4c, also be provided with a rebound 4e.This is will produce very big moment of flexure vertical when being delivered to herein because of the suffered longitudinal force of vehicle, and the force-bearing situation that rebound 4e can improve this place is set, and makes the weld seam more reasonable stress at this place.Simultaneously, in the girth joint joint portion of the cylindrical structure 1a and the conical structure 1b at this place, along its circumferencial direction some of well-distributeds are installed and strengthen gusset 5a.When needs load more goods, then the integral ring-shaped reinforced rib 6a that is made of I-beam section or channel-section steel is installed,, further improves vehicle intensity to substitute above-mentioned reinforcement gusset 5a along its circumferencial direction.According to the variation of load-carrying, the diameter of the cylindrical structure 1a of tank body 1 can be designed to φ 2900～3200mm, and the diameter of continuous conical structure 1b is also done corresponding variation.

Structure of the present utility model is equally applicable to axletree is designed to 25 tons of weights by national standard tank car.
