Problems solved by technology
At present, when domestic blast furnaces are repairing and replacing the middle section of the air supply device, they all adopt the chain-down hoisting method for replacement. Due to the heavy weight of the middle section, during the replacement process, workers pull the air supply device from the ground to the installation position, which is labor-intensive and requires maintenance. It takes a long time, and at the same time, there is a safety hazard of the chain or the breakage of the rope buckle when using the inverted chain hoisting

The invention provides a middle joint replacing device used for replacing a middle joint in a blast furnace air supply system. The device comprises a forklift base, a supporting plate, a left clampingbase, a right clamping base, a left protection arm and a right protection arm. The supporting plate is perpendicular to the forklift base, one side of the supporting plate is fixed to the forklift base, the left clamping base is arranged on the side, away from the supporting plate, of the forklift base, the right clamping base is parallel to the left clamping base and arranged on the side, away from the supporting plate, of the forklift base, one end of the left protection arm is fixedly connected with the end, away from the forklift base, of the supporting plate, one end of the right protection arm is fixedly connected with the end, away from the forklift base, of the supporting plate, a preset angle is formed between the left clamping base and the forklift base, the left clamping base is in clamped connection with a first flange, and the distance between the left protection arm and the right protection arm is not smaller than the outer diameter of the middle joint. By means of the technical scheme, the middle joint replacing device is used in cooperation with a forklift, 3-4 h of overhaul time can be saved, the labor intensity of workers is greatly lowered, and the problem thatsafety accidents happen in the up-down lifting process when a chain block is used is avoided.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a middle section replacement device. Background technique [0002] The middle section of the air supply device is the channel connecting the hot blast surrounding pipe and the blast furnace body, consisting of connecting pipes and expansion joints, with built-in refractory materials. The main function is to send the hot air sent by the hot air surrounding pipe into the hearth of the blast furnace through the air supply device. At present, when domestic blast furnaces are repairing and replacing the middle section of the air supply device, they all adopt the chain-down hoisting method for replacement. Due to the heavy weight of the middle section, during the replacement process, workers pull the air supply device from the ground to the installation position, which is labor-intensive and requires maintenance. It takes a long time, and at the same time, there is a pote...
