Because the railway freight flatcar is based on the transportation standard container, keystone configurations such as its body construction, locking device are all similar.In order to load and transport spare parts of goods and mechanized equipment, improve its commonality, on flat car special used for container, add structures such as installed floor and floor stringer thereof and developed dual-purpose flatcar.Two serial flatcars of the dual-purpose flatcar of flat car special used for container and flatcar-freight container are general flatcar, and domestic to have quantity maximum.Double-deck container flat car is a flatcar newly developed in recent years with carrying two serial flatcars of the back of the body-container lorry on the back, is subjected to the restriction of railway clearance and China's actual conditions, and its application space is difficult to enlarge.
The technical development of railway freight flatcar largely relies on the development of bogie technique and develops.At present, the maximum heavy bogie truck of 40t macro-axis that adopts of China is subjected to the restriction of its load-carrying capacity, and the load limit of railway freight flatcar is in 70t level and following level.This especially is restricted transporting the complete machine equipment that can not disassemble more than the 70t for loading the above goods of 70t, can only transport by the extremely low special-use vehicle with multi axle truck of specific limited and Occupation coefficient is arranged, and the traffic cost height, conveying efficiency is low.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of load-carrying big and be applicable to the Heavy-Haul Railway shipping flatcar underframe of heavy engineering equipment, the combination of multiple freight container and spare parts of goods transportation.
For achieving the above object, the designed Heavy-Haul Railway shipping flatcar underframe of the utility model comprises central sill, is positioned at the curb girder of central sill both sides, is fixed on the end carriage at central sill and the vertical two ends of curb girder, and it is inboard and be fixed on sleeper beam between central sill and the curb girder to be arranged at two end carriages.Described central sill by central sill lower cover, central sill upper cover plate and vertically be arranged in the central sill lower cover and the central sill upper cover plate between two middle webs constitute, be fish belly deformation cross section box-structure; Be furnished with the central sill dividing plate in the described box-structure inner chamber at interval.
Further, in order to improve the load-carrying capacity of underframe, make things convenient for the freight container locking, four jiaos of places of the framework that described central sill and curb girder surrounded are provided with the longitudinal beam that two ends are welded in end carriage and sleeper beam respectively admittedly; Between the curb girder of described central sill and both sides and the clear width that is positioned at the two ends sleeper beam be furnished with lock crossbeam and supporting traverse; The framework top that described central sill and curb girder surround is provided with the floor.
Described lock crossbeam by crossbeam lower cover, crossbeam upper cover plate and vertically be arranged in the crossbeam lower cover and the crossbeam upper cover plate between two cantilever diaphragms constitute, be box-structure; Described lock crossbeam is furnished with cross member dash near between two cantilever diaphragms of curb girder one end; Described cross member dash top is provided with the freight container lock, and the freight container lock is affixed as crossbeam upper cover plate extendible portion and lock crossbeam.
Again further, alleviate dead weight of vehicle in the time of for proof strength, described central sill upper cover plate, central sill lower cover and middle web are by the welding of different-thickness steel plate and form.
Further, for the ease of when loading and transporting loose mail goods being fixed, the curb girder outside of described both sides is vertically arranged with the binding pole socket; The end carriage arranged outside at described two ends has the binding ring seat.
Advantage of the present utility model is: the central sill of designed Heavy-Haul Railway shipping flatcar underframe is for to be made of central sill lower cover, central sill upper cover plate and two middle webs, be fish belly deformation cross section box-structure, and central sill upper cover plate, central sill lower cover and middle web are by the welding of different-thickness steel plate and form, the equal strength design has improved the load-carrying capacity of underframe effectively, has reduced dead weight of vehicle simultaneously.
Be arranged at the load-carrying capacity that lock crossbeam between central sill and the curb girder and supporting traverse have improved underframe.The freight container lock is set on the lock crossbeam can lock to it when the delivery freight container.The binding pole socket that the curb girder outside vertically is provided with and the binding ring seat of end carriage arranged outside can fix goods when the shipment loose mail, and the binding position are unfixing, has alerting ability.The heavy bogie truck of the utility model Heavy-Haul Railway shipping flatcar underframe assembling 40t macro-axis can make the car load design load reach 100t, is applicable to heavy engineering equipment, the combination of multiple freight container and spare parts of goods transportation.
