The invention discloses a guide wheel protective cover and a protective frame, and relates to the technical field of rail transit. The guide wheel protective cover comprises a movable protective cover and a fixing piece. The movable protective cover is used for being rotatably arranged on the side, away from the ground, of the framework through the supporting base, the opening direction of the movable protective cover faces a rim, close to one end of the power receiving rail, of the guide wheel, and the fixing piece is used for being arranged on the framework. When the movable protective cover rotates to the first limit position, the movable protective cover is opened, the rim of the guide wheel is exposed, an operator can maintain the guide wheel, when the movable protective cover rotates to the second limit position, the movable protective cover is closed and located above the guide wheel, and the rim, close to one end of the power receiving rail, of the guide wheel is shielded by the movable protective cover. And when the movable protective cover rotates to the second limit position, the movable protective cover is connected with the fixing piece, and the movable protective cover is made of an insulating material, so that the situation that the rim of the guide wheel is affected by the powered rail to generate electric corrosion can be avoided.

    本发明公开的导向轮防护罩和防护架涉及轨道交通技术领域,包括活动防护罩和固定件。活动防护罩用于通过支撑座可转动的设置于构架远离地面的一侧,且活动防护罩的开口方向朝向导向轮靠近受电轨一端的轮辋,固定件用于设置于构架上。当活动防护罩转动至第一极限位置,活动防护罩打开,导向轮的轮辋外露,可供作业人员对导向轮进行维护,当活动防护罩转动至第二极限位置,活动防护罩闭合并位于导向轮的上方,导向轮靠近受电轨一端的轮辋被活动防护罩遮挡,实现对导向轮轮辋的防护,且当活动防护罩转动至第二极限位置,活动防护罩与固定件连接,其中,活动防护罩由绝缘材料制备,可以避免导向轮的轮辋受到受电轨的影响发生电蚀。
