The utility model discloses a blast furnace air duct maintenance device, which comprises a car chassis, a transmission mechanism, a driving mechanism and a braking mechanism, and can drive on a platform under the blast furnace air duct; The power system is set on the vehicle chassis to provide power for vehicle driving; Platform, set above the vehicle chassis; Platform lifting device, installed on the vehicle chassis and connected with the platform, is used to control the movement of the platform in the direction perpendicular to the vehicle chassis; The air duct holder is placed directly above the platform to place the air duct; One end is connected with the air duct holder and the other is connected with the platform to make the air duct holder move laterally relative to the platform. With the above structure, the chassis of the car can control the device to move under the blast furnace air duct. When loading and unloading the air duct, the platform can move to the appropriate position through the control of the lifting device. The left and right positions of the air duct holder can be adjusted by adjusting the lateral movement device of the air duct holder, without manual replacement, which improves the production efficiency.
The blast furnace duct maintenance device (see the attached figure) is a new device invented by our company in 2009, including the chassis, transmission mechanism, traveling mechanism and manufacturing mechanism, which can drive on the platform under the blast furnace duct; The power system is set on the vehicle panel to provide power for vehicle driving; Platform, set above the vehicle chassis; Platform lifting device, installed on the vehicle chassis and connected with the platform, is used to control the movement of the platform in the direction perpendicular to the vehicle chassis; The air duct holder is placed directly above the platform to place the air duct; One end of the air duct holder is connected with the lateral moving device of the air duct holder, and the other end is connected with the platform to make the air duct holder move laterally relative to the platform. With the above structure, the chassis of the car can control the device to move under the blast furnace air duct. When loading and unloading the air duct, the platform can move to a proper position through the control of the lifting device, and the left and right positions of the air duct holder can be adjusted by adjusting the lateral movement device of the air duct holder, without manual replacement, providing production efficiency.
