Abstract
The invention relates to a railway concave-bottomed flatcar chassis comprising a middle beam, side beams, transverse beams, and a floor plate. The side beams arranged on two sides of the middle beam are parallel to the middle beam. The middle beam and the side beams are fixedly connected through the transverse beams. The floor plate is arranged above the middle beam, the side beams and the transverse beams. Each of the middle beam and the side beams is in a concave-middle structure, with slope transitions between the middle and ends. Two locking channels are fixedly connected to the floor plate on two sides of the middle concave bottom of the middle beam respectively. The lower end of the middle concave bottom of the middle beam and the lower ends of the middle concave bottoms of the side beams are both fixedly connected with lower cover plates. Each of the middle beam and the side beams comprises an upper cover plate, webs vertically fixedly connected to the lower end of the upper cover plate, and one lower cover plate fixedly connected to the lower ends of the webs. Partitions are arranged between the webs of each of the middle beam and side beams for reinforcement. The outer side of the middle concave bottom of the upper cover of each side beam is provided with a row of holes, and each corresponding part of the floor plate above the side beams is also provided with a row of holes. The inner web of each side beam is shorter than the outer web of the corresponding side beam. The inner sides of two ends of the lower cover plate of each side beam are both provided with notches used for avoiding interference between the side beams and a bogie.
Description
Technical field
The present invention relates to a kind of rail wagon base frame, particularly about a kind of for transporting the railroad well car underframe of wheeled car.
Background technology
Railroad well car is generally used for the higher goods of transportation.The middle part concave bottom of the railroad well car such as D10 type and end adopt the transient mode of approximate right angle, exist to be inconvenient to roll fill to roll the shortcoming of unloading Wheel type goods.The railroad well car such as D11 type can realize rolling voluntarily to fill to roll and unload, but because its concave bottom place adopts without center sill structure, therefore underframe vertical stiffness is less, and load-carrying capacity is lower.In addition existing railroad well car generally adopts steel floor structure, loads after wheeled car and can not adopt the modes such as nail triangle crosspiece to fix Wheel type goods, conventionally needs more rope etc. to bundle reinforcing, therefore has the shortcomings such as loading and reinforcing inconvenience.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of facilitate wheeled car roll dress roll unload, rigidity is large and be convenient to the railroad well car underframe of loading and reinforcing.
For achieving the above object, the present invention takes following technical scheme: a kind of railroad well car underframe, it comprises a central sill, one is parallel with described central sill and be arranged on the curb girder of its both sides, and some transverse beams and that are fastenedly connected described central sill and curb girder are laid on the floor of described central sill, curb girder and transverse beam top; It is characterized in that: described central sill and curb girder are the recessed structure in middle part, middle part and two ends all adopt slope transition, on the described floor of the both sides of the middle part concave bottom of described central sill, be all fastenedly connected a draw-in groove, the lower end of the middle part concave bottom of described central sill and curb girder is fastenedly connected a lower cover; Described central sill and curb girder include a upper cover plate, and two are vertically fastenedly connected at the web and of described upper cover plate lower end and are fastenedly connected the lower cover in web lower end; Between two webs of described central sill and curb girder, all adopt some dividing plates to reinforce; On the concave bottom outside, upper cover plate middle part of described curb girder and the described floor on it, opposite position all offers a row for embedding the hole of stiffener, the web length of described curb girder inner side is less than the web length in outside, be the web of described inner side by the end of approaching roller bearing adapter stabilizer bar place, a gap for avoiding described curb girder and bogie truck to interfere is all offered in inner side, the two ends of the lower cover of described curb girder.
The ramp angles of described central sill and curb girder is 10 ゜～15 ゜.
The upper plane of described curb girder is lower than the upper plane of described central sill, and diff-H is 100mm～250mm.
Described transverse beam comprises that the second upper cover plate, two is fastenedly connected the second web below described the second upper cover plate and is fastenedly connected the second lower cover in described the second web lower end, described the second upper cover plate and the second web are stepped, high one end is fastenedly connected described central sill, and the other end is fastenedly connected described curb girder.
Described floor is that steel plate splicing forms, and is close to the top that covers described central sill, curb girder and transverse beam by welding.
Described draw-in groove is that steel and cross section are oblong or trapezoidal strip structure.
The present invention is owing to taking above technical scheme, and it has the following advantages: 1, because the concave bottom of central sill of the present invention and curb girder adopts the slope of 10 ゜～15 ゜ to be connected with end, therefore facilitate rolling voluntarily of wheeled car to fill to roll and unload.2, be fastenedly connected curb girder because the present invention adopts central sill both sides by transverse beam, and top arranges floor, the below of central sill and curb girder concave bottom arranges lower cover, and therefore rigidity is large.3, on the floor due to central sill concave bottom of the present invention both sides, be provided with draw-in groove, and on two curb girder concave bottoms outsides and the floor on it, offer porosely, therefore facilitate the fastening wheeled car of the reinforcing members such as triangle crosspiece.4, because the concave bottom place of curb girder of the present invention adopts two web structure, two ends only adopt outer coxostermum and lower cover one end to offer gap, therefore not only can improve concave bottom place rigidity, but also can avoid interfering with the bogie of car.5, use time of the present invention, the vehicle transporting is generally carried on curb girder, curb girder upper surface of the present invention is than the low about 100mm～250mm of central sill upper surface, has therefore increased the altitude range that the present invention can carrier.
