Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to coal car auxiliary equipment field, concretely relates to a coal car anti-abrasion device. BACKGROUND
[0002] The coke oven front area travelling crane is an important step to ensure that coke is transported to the elevator, and the power supply equipment is indispensable for the five coke oven locomotives. The coal car works when the grinding brush is pressed on the upper surface of the coke oven grinding slide and connected with the locomotive through the brush connecting frame. The main function is to guide the electric energy from the grinding brush to the locomotive through the contact with the grinding slide. The running track of the collecting electrode on the grinding slide is stable and straight in production. The collecting electrode is in full contact with the grinding slide during power supply operation, which ensures stable voltage. In production, the grinding slide will expand and contract due to the influence of the environment and temperature. When the stress cannot be released, the grinding slide will bow up. In severe cases, it will break the pressure plate screw and cause its own fracture, which will cause the collecting electrode to not run normally on the slide in a straight and stable manner, ground or short-circuit, which not only affects production but also has great safety hazards, and has great improvement space.
