Problems solved by technology

[0003] The traditional method of chute replacement requires the use of tools such as counterweight frame, hoist crane, wire rope, and crown block, and is realized by manual command and coordination. The replacement process is complicated, poor in repeatability, and difficult to adjust. It requires a large number of workers and requires a high level of proficiency in the operation. High, generally takes more than 6 hours
Because the whole process of replacement requires the blast furnace to shut down, it causes economic losses

Abstract

The invention relates to a rapid mounting and dismounting mechanism used for a distribution chute replacing device. A fixed support of the distribution chute replacing device is blocked and hung on an access door by arranging a blocking and hanging structure, then the fixed support is locked on the access door by virtue of a locking structure, and the fixed support can be rapidly unlocked, so that rapid mounting and dismounting of the distribution chute replacing device are realized. The invention also relates to a distribution chute replacing system. The distribution chute replacing system comprises the distribution chute replacing device and the rapid mounting and dismounting mechanism, wherein the distribution chute replacing device is used for clamping a distribution chute by virtue of a clamping mechanism and a driving mechanism, and rapid dismounting and mounting of the distribution chute can be realized. By combining the distribution chute replacing device with the rapid mounting and dismounting mechanism, time for replacing the distribution chute can be obviously shortened, so that damping-down time of a blast furnace is shortened, and production efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of blast furnace ironmaking, and in particular relates to a quick assembly and disassembly mechanism of a distribution chute replacement device and a distribution chute replacement system. Background technique [0002] The distribution chute is an important part of the bellless top equipment of the blast furnace, and its function is to cooperate with the distributor to put the charge into the furnace. Due to the long-term resistance to strong impact and friction of ore and coke, as well as exposure to high-temperature working environments, the distribution chute is prone to wear or deformation and affects use, and must be replaced in time. Generally, the average service life of the distribution chute is 3-6 months. [0003] The traditional chute replacement method needs to use tools such as counterweight frame, hoist crane, wire rope and crown block, and is realized by manual command and coordination. The r...
