Assistant vehicle light-reflecting warning flag for open-pit mining area

Abstract

The invention discloses an assistant vehicle light-reflecting warning flag for an open-pit mining area. The assistant vehicle light-reflecting warning flag comprises a bottom plate, a frame and a warning picture are fixed on the side face of the bottom plate, a cavity is formed inside the frame, a magnet block is fixed inside the cavity, a cylindrical barrel and a retaining plate are fixed on theside face of the bottom plate, a rotating rod is movably mounted inside the cylindrical barrel, a moving rod is fixed at one end, away from the cylindrical barrel, of the rotating rod, a magnet strippenetrates the side face of the moving rod, a sponge strip is fixed at the bottom of the moving rod and contacts with the warning picture, and a groove is formed in the bottom of the rotating rod andmovably connected with the retaining plate in a clamped manner. Dust on the surface of a warning picture of the sponge strip is cleaned timely by utilizing homopolar repellence of magnets and vibration of an assistant vehicle during moving; a fixing step is simplified, and the light-reflecting warning flag is fixed more firmly, thereby having high practicability.

Description

technical field [0001] The invention relates to the technical field of warning devices, in particular to a reflective warning flag for auxiliary vehicles used in open-pit mining areas. Background technique [0002] The warning flag is usually composed of a traction rope, a flag surface and a flagpole. It mainly serves as a warning to people. The auxiliary vehicle in the open-pit mining area often hangs a reflective warning flag. However, due to the large dust in the open-pit mining area, after a long time, A large amount of dust is often attached to the surface of the reflective warning flag, which affects the warning effect of the reflective warning flag. In addition, due to the large vibration when the auxiliary vehicle moves, the reflective warning flag often falls off easily and is not easy to fix. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a reflective warning flag for auxiliary ve...
