Abstract
The invention relates to a middle beam-free railway tank truck body, which comprises a tank body and a sleeper beam web plate, wherein the tank body is arranged on the sleeper beam web plate; and a reinforcing device is arranged on the inner lower part of the tank body right above the sleeper beam web plate. Compared with the conventional structure, the middle beam-free railway tank truck body provided with the reinforcing device greatly reduces the stress of vertical seams, greatly improves the stress condition of a pulled pillow, solves the problem of low reliability of the vertical seams, and solves the contradiction between urgent requirement of tank body diameter enlargement and over high stress of the vertical seams.
Description
Technical field
The present invention relates to a kind of no central sill tank car car body.
Background technology
No central sill tank car is topmost tank car form.The car body of no central sill tank car mainly is made up of tank body and pillow pulling.Calculation of strength and test show that in existing structure, draw beam in the pillow pulling structure and the cross joint stress between the body bolster diaphragm are higher, and the big more tank body rigidity that causes of tank diameter is low more, and this cross joint stress is high more.
This cross joint had once in batches that the situation of cracking occurs in utilization, because pillow pulling is the important carrying structure of tank car, the cracking of this cross joint can cause a significant threat railway operation safety, even tank car occurred and topple oil leak, burning, blast.The stress that reduces cross joint can adopt two kinds of methods usually at present, and the one, do not use very large diameter tank body, but this has limited the heavy lifting of the every linear meter(lin.m.) of tank car, has directly influenced the raising of capacity; Another kind method is to strengthen the tank body wall thickness, but this need consume more steel, and has increased dead weight of vehicle, has also influenced the lifting of capacity.In the existing tank car body construction, body bolster diaphragm is a weakest link in the height minimum at cross joint place.This is owing at the cross joint place, limited by cartridge, limited by tank body, can't adopt bigger height.
Along with the development of railway truck technology, the contradiction between an urgent demand that the tank diameter of tank car strengthens and cross joint stress are excessive has become the major issue that restriction tank car capacity promotes.
Summary of the invention
The object of the present invention is to provide a kind of no central sill tank car car body, increased a kind of reinforcing device, significantly reduce the stress of cross joint than existing structure, greatly improve the pillow pulling force-bearing situation, solve the not high difficult problem of cross joint reliability, also solved an urgent demand that tank diameter strengthens and the cross joint stress contradiction between excessive.
Technical solution of the present invention is: the present invention is a kind of no central sill tank car car body, comprise tank body and body bolster diaphragm, tank body is arranged on the body bolster diaphragm, and its special character is: the place, bottom is provided with reinforcing device in the tank body directly over the described body bolster diaphragm.
Be provided with backing plate between above-mentioned reinforcing device and the tank body.
Be provided with oil discharge outlet between above-mentioned reinforcing device and the tank body.
Above-mentioned oil discharge outlet is semicircle or rectangle.
Above-mentioned reinforcing device is stiffening plate, finishing strips or reinforcing block.
The connection mode of above-mentioned reinforcing device and tank body is welding, riveted joint or clamping.
When above-mentioned reinforcing device was stiffening plate, described stiffening plate was arc or crescent.
The reinforcing device that the present invention proposes, i.e. weld reinforcement plate in the plane of tank interior body bolster diaphragm has been equivalent to increase the height of body bolster diaphragm, has greatly improved the force-bearing situation of cross joint.Finite element analysis shows, under railway truck examination loading, the maximum stress of a kind of typical tank car car body at the cross joint place of no reinforcing device reached 309MPa, after having increased the reinforcing device of the present invention's proposition, the stress at this place has been reduced to 160MPa, decreases by 48%, can greatly improve the reliability of cross joint, avoid occurring fracture, guarantee vehicle operating safety.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A view of Fig. 1 of the embodiment of the invention one;
Fig. 3 is the A-A view of Fig. 2 of the embodiment of the invention two.
The specific embodiment
Referring to Fig. 1,2, the car body of the no central sill tank car that the embodiment of the invention one is provided mainly is made up of tank body 1 and pillow pulling 2, pillow pulling 2 comprises draw beam 3 and sleeper beam 4, be welded in below, tank body two ends, draw beam 3 is along the length of tank direction, and sleeper beam 4 is vertical with draw beam 3.Sleeper beam 4 comprises body bolster diaphragm 7.Body bolster diaphragm 7 is connected by cross joint 8 with draw beam 3.Stiffening plate 5 constitutes reinforcing device, under the effect of load, and the middle part of sleeper beam 4, just cross joint 8 place's force-bearing situations are the most abominable, and body bolster diaphragm 7 is weakest links in the height minimum at cross joint 8 places.Owing to, be subjected to cartridge 9 restrictions downwards at cross joint 8 places, upwards be subjected to tank body 1 restriction, can't adopt bigger height.
In the embodiment of the invention one, stiffening plate 5 is arc, is welded on the interior bottom of tank body 1, matches with tank body 1 inner surface configuration with body bolster diaphragm 7 its lower surface in same plane.Oil discharge outlet 6 is breach opening between stiffening plate 5 and tank body 1, and the shape of oil discharge outlet 6 can be semicircle or rectangle, and welding end and the suitable pipe of its shape on oil discharge outlet 6 is used for oil extraction.Also can add backing plate between stiffening plate 5 and the tank body 1, welding with backing is connected on the tank body 1, and stiffening plate 5 is welded on the backing plate, when increasing stiffening plate, can protect tank body by actv. by such mode.Between stiffening plate 5 and the tank body 1, also can adopt the captive joint mode of riveted joint between backing plate and tank body 1 and stiffening plate 5 and the backing plate.
The reinforcing device that the present invention proposes, weld reinforcement plate 5 in the plane of tank body 1 inner body bolster diaphragm 7 has been equivalent to increase the height of body bolster diaphragm 7, has greatly improved the force-bearing situation of cross joint 8.Finite element analysis shows, under railway truck examination loading, the maximum stress of a kind of typical tank car car body at the cross joint place of no reinforcing device reached 309MPa, after having increased the reinforcing device of the present invention's proposition, the stress at this place has been reduced to 160MPa, decreases by 48%, can greatly improve the reliability of cross joint, avoid occurring fracture, guarantee vehicle operating safety.
Referring to Fig. 3, the stiffening plate 5 in the embodiment of the invention two can also adopt crescent, guarantee lower surface can with tank body 1 inner adaptive and rigidly connected prerequisite under, stiffening plate can also adopt multiple shape.
