Embodiment Construction

[0019] Now in conjunction with accompanying drawing, the present invention will be further described:

[0020] figure 1 , 2 , 3 shows the frame structure of the double-layer top layer of the shunting locomotive. In the figure, the frame structure of the double-layer top layer of the shunting locomotive is connected together by two pot-shaped longitudinal beams 1 and 12 groove-shaped cross-beams 2 . There is a flat top slab 10, and a downward sloping structure is adopted on both sides of the top slab 10, and a longitudinal waterproof eaves 5a are arranged at the lowest point on both longitudinal sides of the frame structure, and horizontal waterproof eaves 5 are arranged on both lateral sides; the frame structure The outer side of the inclined part is provided with an outer skin 3, and the inner side is provided with an inner skin 4 with an inner air inlet 6 to form a hollow double-layer structure 12, and a side air outlet 6b is provided at the lowest point of the hollow doub...

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...
