Abstract

The invention provides a top cover device and a silencer overhead system. The top cover device comprises a concave top cover and a sewage draining pipeline system. A downwards-concave installation groove is formed in the concave top cover, at least one funnel communicated with the installation groove is formed below the bottom face of the installation groove, and the funnel is connected with the sewage draining pipeline system. The silencer overhead system comprises a silencer and the top cover device. The silencer is arranged in the installation groove in the concave top cover in the top cover device. The silencer is arranged on the top cover of a locomotive, the problem that the installation space below the locomotive is compact is solved, the heat dissipating problem of the silencer is solved, and the arrangement difficulty of a silencer pipeline is lowered. Meanwhile, the top cover device is arranged for the silencer in a targeted mode and used for fixation and sewage drainage, the problem that the overhead silencer is more likely to be corroded by dirt such as rain and snow is solved, and the service life of the silencer is prolonged.

Description

technical field [0001] The invention relates to heat dissipation of a muffler of a diesel locomotive, in particular to a top cover device and a muffler overhead system. Background technique [0002] The muffler is an important part of a diesel locomotive, and its main function is to discharge the exhaust of the diesel locomotive and eliminate noise. The existing muffler layout structure generally adopts the form of suspension at the bottom of the vehicle frame. [0003] However, the form of bottom suspension occupies a large amount of installation space under the vehicle frame, thereby reducing the installation space of other components, making installation difficult, increasing the difficulty of component maintenance, and also increasing the difficulty of the arrangement of the muffler pipeline. At the same time, when the muffler emits exhaust gas, it will generate a lot of heat. Due to heat conduction, the layout of the suspension installation at the bottom of the frame w...
