The detachable top cover of the locomotive is suitable for a rail flaw detection locomotive and a line measurement locomotive, and facilitates sealing and blocking operations of locomotive ceiling hoisting equipment passage of the rail flaw detection locomotive and the line measurement locomotive, the top cover is connected with the locomotive ceiling through the edge beam, the load of the top cover is uniformly distributed on the locomotive ceiling due to the edge beam, so that the stress concentration defect is prevented; the detachable top cover is convenient to dismount, so that equipment in the topcover can be maintained conveniently; the wind guide cylinder is arranged in the middle of the top cover, the wind inlet channel is reserved between the rainproof plate and the wind guide cylinder, and the wind guide cylinder on the top cover can improve efficiency of the wind inlet system and prevents rain water from entering the locomotive through the channel.

Description

technical field [0001] The invention belongs to the field of locomotive equipment, and more specifically relates to a detachable top cover of a locomotive. Background technique [0002] With the development of my country's railways, the requirements for rails are getting higher and higher, and the requirements for vehicle functions will be higher and higher. At this time, large-scale equipment in the vehicle needs to enter the vehicle through the channel reserved on the roof In the car, the air intake motor in the car is installed on the top cover, and the requirements for the top cover are getting higher and higher. The current structure of the top cover cannot accommodate a heavy motor, and the sealing performance between the top cover and the roof is poor. , The problem of inconvenient disassembly and assembly. [0003] Therefore, in order to solve this problem, a kind of locomotive detachable top cover is proposed. Contents of the invention [0004] The purpose of the ...
