Description

Anti-drop inspection hole cover of traction motor of diesel locomotive Technical Field The utility model relates to the technical field of railway crossings, in particular to an anti-drop inspection hole cover of a traction motor of an internal combustion locomotive. Background The structure of the direct current traction motor is provided with a commutator and carbon brushes, and after the motor runs for a period of time, the carbon brushes need to be replaced, so that an observation hole is arranged on the base of the direct current traction motor. Typically, these view ports are used for the sealing of the view port cover, which is opened when it is desired to view the inside of the motor or to replace the carbon brushes. At present, the internal combustion locomotive happens when the fault that the inspection hole cover of the traction motor falls down in the running process, and in the application process, the reasons that the upper part of the inspection hole cover is cracked, detached and the spring clip fails are found, so that the motor cover is easy to fall off, the traction motor cover falls off, on one hand, moisture, dust, running foreign matters and the like can be caused to enter the motor, the insulation of the motor is reduced, and serious mechanical accidents such as motor burning and the like are caused, and on the other hand, if the motor cover falls off on a steel rail, serious potential safety hazards of train subversion are possibly caused. Disclosure of utility model The utility model aims to solve the problems that in the prior art, the motor cover is easy to fall off due to the reasons of cracks, welding off and failure of a spring clamp at the upper part of the inspection hole cover, and the traction motor cover falls off, and provides an anti-falling inspection hole cover of a traction motor of a diesel locomotive, which is fixed through the existing hasp and has secondary protection of an anti-falling connection structure, so that the anti-falling reliability of the inspection hole cover is greatly improved, and the falling risk of the inspection hole cover is effectively reduced.
