The utility model relates to a device for installing steel bricks and protecting plates at a blast furnace throat, which is composed of a machine frame, a lifting mechanism and an ejector mechanism, wherein, the machine frame can rotate 360 DEG, and the lifting mechanism can drive the ejector mechanism to rise and fall. The four telescopic arms of the ejector mechanism are driven by hydraulic power, and can extend forward and retract backward, so that the steel bricks and the protective plates clamped on a chuck of one ejector arm at the front end of the ejector mechanism can be successfully arranged on any position of the circumferential direction of a blast furnace. Compared with manual chain fall installation at present, using the device can increase efficiency by three times, and quality and safety are ensured. The utility model relieves workers' burdensome labor, and thus is suitable for the large and the medium maintenance of the blast furnace.
