Description

Technical Field

[0001] The utility model relates to the technical field of railway locomotives, in particular to rain test equipment for railway locomotive accessories. Background Art

[0002] Locomotives are generally driven directly or through transmission devices by power machinery such as steam engines, diesel engines, gas turbines, and traction motors. The power machinery causes the locomotive's driving wheels to generate torque, and at the same time the road gives the driving wheels an equal and opposite reaction force. The sum of the reaction forces of each driving wheel is called the locomotive traction force. This traction force is a tangential external force generated by the force acting on the driving wheel circumference, so it is also called wheel circumferential traction. When testing locomotive accessories, the existing rain test box only simulates the rain environment, without the coordinated simulation state of wind force, and the experimental simulation effect is not good; and using tap water to simulate the rain environment, in the long-term experiment, a large amount of water resources is wasted, and it is not suitable for long-term continuous simulation, and the overall usability is low. Application No. 201921715386.9 discloses a rain test device based on railway locomotive accessories. The rain test box based on railway locomotive accessories is used for testing locomotive accessories. The test device comprises: a test box; a mounting frame, one side of the two mounting frames are fixed to the right side of the inner wall of the test box, and the side of the mounting frame away from the test box is fixedly connected to a power box, and the right side of the power box is fixedly connected to a connecting frame; a rotating rod, the bottom end of the rotating rod is rotatably connected to the bottom of the inner wall of the power box, and the top end of the rotating rod is fixedly connected to a rotating frame. The utility model provides a rain test device for railway locomotive accessories, which has the advantages of being able to spray by providing a spray component, being able to spray at multiple angles, being able to simulate the natural state of rain spraying, having diversified simulation states and good simulation effects; and being able to achieve a wind force coordination simulation state for the spraying by providing a fan, thereby improving the experimental effect.

[0003] The test device of the above structure can only simulate the equipment condition during normal rain. However, in special weather conditions, the rainwater is often acidic and will cause strong corrosion to the equipment, so it is necessary to simulate this spraying condition. Utility Model Content
