Description

Technical Field

[0001] The utility model relates to a rock drill protection device, belonging to the technical field of blast furnace production equipment in the metallurgical industry. Background Art

[0002] The rock drill is a commonly used equipment for the blast furnace taphole. During the blast furnace production process, the taphole is chiseled open by an opening machine rock drill. The front end of the rock drill frame directly faces the high-temperature molten iron sprayed from the taphole. In order to protect the blast furnace rock drill frame from being damaged by the high-temperature molten iron, a protective plate is set at the front end of the frame. The protective plate is an integral structure. When a local part of the protective plate is damaged, the entire protective plate needs to be replaced, which undoubtedly causes waste, and the protective plate is troublesome to disassemble and difficult to repair; in addition, the part of the rock drill located at the main ditch also lacks protection and is easily damaged by high temperature. Utility Model Content

[0003] The utility model aims to provide a rock drill protection device which adopts a combined structure, is easy to assemble and disassemble, has a good protection effect, avoids the damage of high-temperature molten iron to the rock drill, and solves the problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A rock drill protection device comprises a rock drill, a rock drill bottom plate, a front baffle and a U-shaped guard plate, wherein the front baffle and the U-shaped guard plate are respectively fixed on the rock drill bottom plate, the U-shaped guard plate is a U-shaped frame structure, the rock drill is located in the U-shaped guard plate, and the front baffle is located in front of the rock drill.

[0006] The U-shaped guard plate is a U-shaped structure formed by connecting a guard plate bottom plate and two vertical plates, and the two vertical plates are respectively fixed to the rock drill bottom plate through guard plate fixing bolts.

[0007] The guard plate bottom plate in the U-shaped guard plate is a double-layer plate, and rock wool is arranged between the double-layer plates.

[0008] The thickness of the rock wool between the double-layer boards is 50-80 mm.

[0009] The front baffle is provided with an anchor hook and spray material on the side facing the blast furnace.

[0010] The front baffle is provided with an arc-shaped groove matched with the drill rod of the rock drill.

[0011] The utility model has the beneficial effects of: adopting a combined structure, being easy to assemble and disassemble, and having a good protective effect, thus preventing the rock drill from being damaged by high-temperature molten iron. BRIEF DESCRIPTION OF THE DRAWINGS
