Description

Return roller replacement device {RETURN ROLLER CHANGE APPARATUS}

The present invention relates to a return roller replacement device, and more particularly to a return roller replacement device that can replace the return roller safely and conveniently while the belt conveyor is operating.

In general, a belt conveyor is a facility used to transport goods (such as raw materials and fuel) to a designated place in a steel mill or a power plant.

As shown in FIG. 1, the belt conveyor A includes a frame 1, a plurality of carrier rollers 2 installed on the frame 1 to be spaced at a predetermined distance in the longitudinal direction, and the frame 1. It is composed of a plurality of return rollers (3) provided to be spaced apart at a predetermined interval in the longitudinal direction at the bottom of the), and the belt (A) connected to circulate the carrier roller (2) and the return roller (3).

In particular, in the above-described configuration, the return roller 3 has a limitation in use that must be replaced after a certain time because the load is concentrated on the rotating shaft and the bearing formed on both sides due to the property of supporting the tension and the load of the belt 5.

However, in order to replace the return roller 3, it is necessary to stop the belt conveyor A in operation, and as a result, it delays the work process, thereby providing a cause of enormous economic loss.

In addition, in order to replace the return roller 3, the operator has to work on the lower part of the belt conveyor (A), thereby reducing the work efficiency and providing a cause of a safety accident.

In addition, since the weight of the return roller (3) is considerable, a number of workers have to replace the work at the same time is difficult to work quickly and there is a problem of providing a cause of a safety accident.

Therefore, as a way to solve the above problems, an apparatus for replacing the return roller on behalf of the operator has been proposed and the related technology is Republic of Korea Patent Publication No. 2002-0052392 belt conveyor return roller exchange device (hereinafter referred to as the prior art) Is disclosed.
