Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, the two end beams 11 of each vehicle underframe unit 10 of the railway freight car are fixedly connected with an end steel floor 20 respectively, and several middle steel floors 30 and several wooden floors 40 are arranged in the middle. Wherein, both ends of each central steel floor 30 are respectively fixedly connected with two side beams 12 of the vehicle underframe unit 10 , and the middle part is fixedly connected with the middle beam 13 of the vehicle underframe unit 10 . Some wooden floors 40 are arranged between every two steel floors 30 in the middle, and the number of them can be adjusted according to the size of the goods loaded on the vehicle. Both ends of each wooden floor 40 are fixedly connected to the two side beams 12 of the vehicle chassis unit 10 . Since the wooden floor 40 will be squeezed and de...

Abstract

The invention relates to a composite floor for a rail wagon, which is characterized in that two end beams of each automotive chassis unit of the rail wagon are respectively and fixedly connected with an end part steel floor, and the middle of each automotive chassis unit is provided with a plurality of middle steel floors and wood floors, wherein two ends of each middle steel floor are respectively and fixedly connected with two side beams of the automotive chassis unit, and the middle of each middle steel floor is fixedly connected with the middle beam of the automotive chassis unit; a plurality of wood floors are arranged between every two middle steel floors, and the number of the wood floors can be adjusted based on the size of goods loaded by a vehicle; two ends of each wood floor are fixedly connected with the two side beams of the automotive chassis unit; and the upper plane of each wood floor is higher than the upper plane of each middle steel floor. The composite floor for the rail wagon has high rolling compaction resistance and rust resistance, is convenient in maintenance and can be widely paved on various rail wagons.

Description

technical field [0001] The present invention relates to a floor, and more particularly to a composite floor for use on railway wagons. Background technique [0002] Flat cars and shared flat cars in railway wagons are mainly used to transport wheeled equipment, crawler equipment, mechanical equipment and other goods, and sometimes they can also be used to transport special long goods such as steel rails and prefabricated beams, as well as super long goods that need to be straddled. goods. At present, the floor of the flat car in the railway freight car and the shared flat car generally use wooden floor as the structural unit. The use of wooden floor can increase the friction between the loaded goods and the floor, which is conducive to the fastening safety of the loaded goods. At the same time It can also reduce the time and cost of loading and reinforcing goods. However, there are also some problems in this pure wooden floor structure, such as: the wooden floor structure ...
