Description
Technical field
The present invention relates to the tank car field, relate in particular to a kind of without central sill rail road tank car traction and bolster structure.
Background technology
Be topmost tank car form without the central sill tank car, pillow pulling is the main carrying structure without the central sill tank car, plays a part to support tank body and transmits the train longitudinal force.Pillow pulling is mainly by forming along the draw beam of longitudinal direction of car with along the sleeper beam of lateral direction of car.In utilization, pillow pulling cross joint and sleeper beam lower cover all once had the situation of cracking to occur, and railway operation safety is caused a significant threat, even tank car may occur and topple oil leak, burning, blast.
Along with technical development, the tank car load-carrying is increasing, and the load that pillow pulling bears heavily increases with carrying further, and the performance of the antifatigue cracking of pillow pulling structure has become and improved the major issue that needs to be resolved hurrily in tank car load-carrying and the capacity process.The pillow pulling structure of modal a kind of tank car is at present: pillow pulling comprises draw beam and sleeper beam, and the draw beam web is connected fillet weld with body bolster diaphragm and connects, and this fillet weld is called cross joint, and the sleeper beam gusset is shaped as trapezoidal, and sideline, the outside is straight line.The shortcoming of this structure is:
1, body bolster diaphragm directly is connected by cross joint with the draw beam web, and the stress that cross joint bears is very high, and anti-fatigue performance is poor, to having relatively high expectations of welding.Finite element analysis computation and tank car commissioning test have proved that all the stress that cross joint bears is higher.The situation of cross joint cracking also once appearred in this structure in utilization, the transporting safely of serious threat tank car dangerous material.
2, the sleeper beam gusset is shaped as trapezoidally, and sideline, the outside is straight line, and place, the summit support stiffness that this sideline and gusset base are intersected is large, simultaneously because summit stress is concentrated, cause this place weld seam fatiguability cracking, this problem once appearred in existing tank car, the transporting safely of serious threat tank car dangerous material.
3, the sleeper beam outside is side pipe pillar or with the rectangular steel plates of bending.The summit support stiffness that side pipe pillar or rectangular side cover plate are connected with tank body is large, because summit stress is concentrated, makes this place's weld seam become potential endurance crack source simultaneously, threatens transporting safely of tank car dangerous material.
Summary of the invention
In order to solve existing technical matters in the background technology, the present invention proposes a kind ofly without central sill rail road tank car traction and bolster structure, the circular arc attaching parts is adopted in the commissure, has solved high, the poor problem of anti-fatigue performance of stress that cross joint bears.
Technical solution of the present invention is: without central sill rail road tank car traction and bolster structure, comprise sleeper beam, draw beam, described sleeper beam is symmetricly set in the draw beam both sides, and sleeper beam comprises side cover plate under the sleeper beam, sleeper beam gusset and body bolster diaphragm, and described body bolster diaphragm is arranged under the sleeper beam on the side cover plate; Described draw beam comprises draw beam web and the draw beam lower aerofoil vertical with the draw beam web; Described sleeper beam gusset is arranged on vertical gusset of the bending region of the close draw beam of side cover plate under the sleeper beam, between described body bolster diaphragm and the draw beam web stiffener is set, and its special character is: described stiffener is the cambered surface stiffening plate.
Above-mentioned sleeper beam gusset is the right-angled trapezium gusset, and the side of described right-angled trapezium gusset is arc.
Above-mentioned sleeper beam two ends arrange the sleeper beam side cover plate that is positioned at mutual vertical plane surface with sleeper beam, and described sleeper beam side cover plate comprises the side cover plate matrix, and described side cover plate matrix upper end arranges convex shoulder, and described convex shoulder and side cover plate matrix are L-shaped.
Above-mentioned arc stiffening plate is two, and the two ends of two arc stiffening plates are connected with the draw beam web with body bolster diaphragm respectively, forms triangular structure with the draw beam web.
Above-mentioned convex shoulder is connected with side cover plate matrix arc-shaped transition.
Two arc-shaped side edges of above-mentioned trapezoidal gusset are the indent arc-shaped side edges.
Advantage of the present invention is:
1, the cross joint place of body bolster diaphragm and draw beam web arranges watt shape stiffener, and actv. has been shared the stress of pillow pulling cross joint, and cross joint stress is significantly reduced, and has greatly improved the anti-fatigue ability of cross joint;
2, be arranged on the sleeper beam gusset of the bending region of the close draw beam of side cover plate under the sleeper beam, adopt the right-angled trapezium plate, because circular arc has been adopted at middle part, sideline, the outside, reduced the support stiffness of outer side edges, the stress of side cover plate junction under outer side edges two summits and tank body and the sleeper beam is significantly reduced, improved anti-fatigue ability.
3, sleeper beam side cover plate upper end arranges convex shoulder, and the existence of convex shoulder has reduced the support stiffness on two summits, sleeper beam side cover plate 1 top, has reduced stress and has concentrated, and the stress maxim significantly reduces, and has improved the fatigue life of the sleeper beam outside and tank body junction.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to view;
The specific embodiment
Referring to Fig. 1, Fig. 2, of the present invention without central sill rail road tank car traction and bolster structure, comprise side cover plate 3, sleeper beam gusset 4, stiffener 5, draw beam web 6 and draw beam lower aerofoil 7 under sleeper beam side cover plate 1, body bolster diaphragm 2, the sleeper beam; Body bolster diaphragm 2 is arranged under the sleeper beam on the side cover plate 3; Draw beam web 6 is vertical with draw beam lower aerofoil 7; Sleeper beam gusset 4 is arranged on vertical gusset of the bending region of side cover plate 3 close draw beams under the sleeper beam.
Stiffener 5 is for curving the steel plate of circular arc, similar and the tile shape of shape, body bolster diaphragm 2 is connected with the draw beam web and is adopted cross joint to connect, two watts of shape stiffeners 5 are connected to the cross joint both sides, two straight flanges of each watt shape stiffener are connected with the draw beam web with body bolster diaphragm 2 respectively and are connected, upside arc limit is connected with tank body of tank car, and downside arc limit is connected or does not connect with draw beam lower aerofoil 7.Watt shape stiffener 5 actvies have been shared the stress of pillow pulling cross joint, and cross joint stress is significantly reduced, and have greatly improved the anti-fatigue ability of cross joint.
