Abstract

The utility model belongs to the field of a container flat car, particularly relates to a low-gravity center container flat car and solves the problems of higher center, poor operation stability and large self weight of the existing container flat car. The low-gravity center container flat car comprises a flat car adopting a panel installed and welded structure; the flat car comprise a traction beam, a middle beam, an end beam, a sleeper beam, large crossbeams and small crossbeams; the middle beam adopts a dual-web installed and welded box structure and has a fish belly structure with two high end parts and a low middle part; the traction beam, the end beam, the sleeper beam, the large crossbeams and the small crossbeams all adopt thea dual-web installed and welded box structure; a web of the middle beam adopts an upward deflection of 25mm; impact baffles are arranged at two end parts of the car body; a web of the traction beam is outwards bent at the end beam. The height from a container carrying surface of the container flat car to a rail surface is reduced, the car gravity center is reduced, and the operation stability and operation quality of the car are improved; the car body is only installed and welded by panels, so the manufacturing cost is reduced, the self weight of the car is reduced, the car load is improved and the social and economic benefits are obviousremarkable.

Description

Low center of gravity container flat car

Technical field

The utility model belongs to the technical field of container flat car, is 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), generally more than 1140mm, vehicle's center of gravity is higher, and operation stability is poor; Existing container flat car car body is except adopting sheet material assembly welding, and shaped steel part and the steel casting of employing are more, and the production cycle is longer, and dead weight of vehicle is bigger than normal.

Summary of the invention

The utility model is higher in order to solve existing container flat car center, and operation stability is poor, and the production cycle is longer, and the problem that dead weight of vehicle is bigger than normal provides a kind of low center of gravity container flat car.

The utility model 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 at car body middle part, 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-structures, 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-structures, and middle web and draw beam web dock at body bolster diaphragm place.

In order further to optimize the structure of this flatcar, improve its function, the utility model has also carried out following improvement:

Described middle web adopts the upwards amount of deflection of 25mm, can effectively avoid after freight container entrucking, and 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 utility model adopts the impact baffle plate that steel plate is made to replace striker, simple in structure, light.

Described draw beam web, in the outside bending in end carriage place, makes can, along the rotation of certain drift angle, to be convenient to vehicle and to pass through small-curve railway after hitch assembling.

For make hitch apart from the height of rail level still remain on 880mm or more than, described hitch adopts upwards eccentric type structure, gib head center has upwards been offset 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, more than the low 100mm of general container flat car, reduce the freight container carrying surface of container flat car apart from the height of rail level, vehicle's center of gravity reduces, and has improved vehicle operating stability and riding quality; Car body only adopts sheet material assembly welding, has improved production efficiency, has reduced manufacturing cost, reduce dead weight of vehicle, improve vehicle load, dead weight of vehicle deficiency 19t, lighter more than 3 tons than container flat car of the same type, load-carrying maximum can reach 73t, and economic benefit and social benefit are remarkable.
