Abstract
The invention belongs to the field of container flat cars, specifically relates to a low-center-of-gravity container flat car and aims at solving the problems of relatively high center, poor running stability and high car deadweight of the existing container flat cars. The Low-center-of-gravity container flat car comprises a car body. The car body is of a plate welded structure and comprises a towing beam, a middle beam, an end beam, a sleeper beam, a large cross beam and a small cross beam; the middle beam is of a dual-web welded box-type structure, and also of a fish belly-shaped structure high in middle and low in both ends; the towing beam, the end beam, the sleeper beam, the large cross beam and the small cross beam all are of the dual-web welded box-type structures; the webs of the middle beams have the upward deflection of 25mm; impact baffle plates are arranged at the two end portions of the car body; the webs of the towing beams are bent outwards at the end beam. The height of the container bearing surface of the container flat car away from a track surface is reduced, the center of gravity of the vehicle is reduced, and the running stability and the running quality of the vehicle are improved; the car body is welded only by use of plates, so that the manufacturing cost can be reduced, the deadweight of the car can be reduced and the carrying capacity of the car can be improved; in short, remarkable economic benefit and social benefit can be produced.
Description
Technical field
The invention belongs to the technical field of container flat car, be specifically related to a kind of low center of gravity container flat car.
Background technology
The freight container carrying surface height to the top of rail of existing container flat car, (empty wagons) is general at more than 1140mm, and vehicle's center of gravity is higher, and operation stability is poor; Existing container flat car car body except adopting sheet material assembly welding, the shaped steel part of employing and steel casting more, the production cycle is longer, and dead weight of vehicle is bigger than normal.
Summary of the invention
The present invention is higher in order to solve existing container flat car center, and operation stability is poor, and the production cycle is longer, the problem that dead weight of vehicle is bigger than normal, provides a kind of low center of gravity container flat car.
The present invention adopts following technical scheme to realize: low center of gravity container flat car, comprise car body, container locking device, hitch and coupler and draft gear and bogie truck, car body adopts sheet material assembly welding structure, comprise draw beam, central sill, end carriage, sleeper beam, cross bearer, needle beam, draw beam is positioned at car body two ends, central sill is positioned in the middle part of car body, end carriage is positioned at both sides, draw beam end, sleeper beam is positioned at draw beam and both sides, central sill junction, two cross bearers are between two sleeper beams, and two needle beams are between cross bearer and sleeper beam; Wherein central sill adopts two web assembly welding box-structure, and be the low fish belly shape structures in high two ends, middle part, draw beam, end carriage, sleeper beam, cross bearer, needle beam all adopt two web assembly welding box-structure, and middle web and draw beam web dock at body bolster diaphragm place.
In order to optimize the structure of this flatcar further, improve its function, the present invention has also carried out following improvement:
Described middle web adopts the amount of deflection of upwards 25mm, and after can effectively avoiding freight container entrucking, maximum arch place of central sill touches container base, and the fully loaded rear central sill of vehicle produces sagging.
Described car body both ends are provided with impact baffle plate, and existing vehicle end adopts the striker of cast steel material, heavier, and the impact baffle plate that the present invention adopts steel plate to make replaces striker, and structure is simple, light.
Described draw beam web, in the outside bending in end carriage place, can rotate along certain drift angle after hitch is assembled, be convenient to vehicle and pass through small-curve railway.
For making hitch still remain on 880mm or more apart from the height of rail level, described hitch adopts upwards eccentric type structure, and gib head center upwards offset by 35mm than coupler body center.
By adopting new body construction and Novel eccentric hitch, freight container carrying surface is no more than 1040mm apart from the height of rail level, 100mm more than lower than general container flat car, reduce the height of freight container carrying surface apart from rail level of container flat car, vehicle's center of gravity reduces, and improves vehicle operating stability and riding quality; Car body only adopts sheet material assembly welding, improves production efficiency, reduces manufacturing cost, reduce dead weight of vehicle, improve vehicle load, dead weight of vehicle is less than 19t, lighter than container flat car of the same type more than 3 tons, load-carrying is maximum reaches 73t, economic benefit and social benefit remarkable.
