Double-layer top layer of shunting locomotive

Abstract

The invention relates to a double-layer top layer of a shunting locomotive, belonging to the technical field of steel structures of shunting locomotives. The double-layer top layer of the shunting locomotive is of a frame structure characterized in that two basin type longitudinal beams and multiple slot type transverse beams are connected; longitudinal waterproof eaves are arranged in the lowermost positions of the two longitudinal sides of the frame structure, and the two transverse sides the frame structure are provided with transverse waterproof eaves; the outer side of the tilted part ofthe frame structure is provided with outer skin, and the inner side of the tilted part of the frame structure is provided with inner skin with an inner air inlet, thereby forming a hollow double-layer structure; a side air outlet is arranged in the lowermost position of the hollow double-layer structure; the top layer plate of the frame structure is provided with an upper air inlet; and an air ventilation unit is arranged at the upper part of the upper air inlet. The double-layer top layer provided by the invention has the effects of radiation prevention and heat insulation, thereby delivering the outside heat to each mechanical room as less as possible; and the top layer structure has the function of the heat dissipation of indoor equipment, thereby strengthening the rigidity of the top layer.

Description

technical field [0001] The invention relates to a double-layer top layer of a shunting locomotive, belonging to the technical field of steel structures of shunting locomotives. Background technique [0002] The top floor of each mechanical room of the existing shunting locomotive is a single-layer structure. First, there are many basin-shaped longitudinal beams and transverse beams and angle steel bottom beams welded together to form a frame structure on the top floor. become. After the assembly and welding of the product structure is completed, a layer of mud-resistance is sprayed on the inner surface of the top layer. The mud-resistance has the function of heat insulation, but the effect is not very obvious. At the same time, the single-layer top layer has no heat dissipation function, and the rigidity of the single-layer top layer steel structure is also insufficient. [0003] The single-layer roof structure has no effect of radiation protection and heat insulation. Met...

AI Technical Summary

Problems solved by technology

Through analysis and research, it is found that: the existing top layer has no radiation protection and heat insulation effect on the external environment, and at the same time, the cooling function of each room of the locomotive is insufficient, so that the temperature in each room is relatively high
