Method for manually replacing bucket type elevator belt

Abstract

The invention discloses a method for manually replacing a bucket type elevator belt, which comprises the following steps that: firstly, a new belt is conveyed to the tail part of a bucket type elevator, tail observing openings arranged at both sides of the bucket type elevator are opened, and an old belt is disconnected at the tail wheel part of the bucket type elevator from one tail observing opening; then, the prepared new belt is connected with the corresponding broken end of the old belt through the tail observing opening; and workers carry out turning at the head wheel part of the bucket type elevator until the old belt is completely output from the other tail observing opening, the connecting part of the new belt and the old belt is disconnected, and finally, two disconnected ends of the new belt are connected. The method has the beneficial effects that the bucket type elevator belt is replaced by a manual turning method, the work procedure of removing a protecting cover arranged at the head wheel part of the bucket type elevator is omitted, the whole process is simple and is easy to operate, the safety factor is high, the replacement time is short, and the normal production is not influenced.

Description

technical field [0001] The invention relates to a method for manually replacing belts of a bucket elevator, which is suitable for the technical field of blast furnace ironmaking. Background technique [0002] The normal operation of the coal-injection bucket elevator is a decisive factor for the coal volume of the medium-speed mill, and it is the key equipment for whether a blast furnace can normally and stably inject coal powder. In the actual production process, the bucket elevator The belt needs to be replaced every three months. The current replacement method is only one. When replacing, you must contact a 70-ton crane in advance. When replacing, it takes 60 minutes for the crane’s in-and-out legs, pad sleepers, and in-and-out rods; the replacement procedure is complicated and cumbersome. First, remove the head and tail of the bucket elevator Wheel guard, disconnect the old belt from the tail wheel, then hoist the old belt from the first wheel with a 70-ton crane and pu...

The current replacement method is only one. When replacing, you must contact a 70-ton crane in advance. When replacing, it takes 60 minutes for the crane’s in-and-out legs, pad sleepers, and in-and-out rods; the replacement procedure is complicated and cumbersome. First, remove the head and tail of the bucket elevator Wheel guard, disconnect the old belt from the tail wheel, then hoist the old belt from the first wheel with a 70-ton crane and put it on the ground, then hoist the new belt from the ground and place it on the bucket elevator At the first round, finally connect the new belt

This replacement method needs to use a 70-ton crane, which has a low safety factor, complicated replacement procedures, and takes a long time. It takes about 210 minutes each time, and the amount of coal stored in the coal storage bunker is only enough for the medium-speed mill to produce for 90 minutes. Every time a bucket elevator belt is replaced, a production-affecting condition arises
