Description

Reverse meandering device of transport conveyor {APPARATUS FOR ADJUSTING SERPE NTINE MOVING OF TRANSFER CONVEYOR}

The present invention relates to a transport conveyor for transporting raw materials, such as ore and coal, in a steel mill, and more particularly, to prevent SERPENTINE MOVING of the conveyor belt, and in particular, by overloading the transport conveyor. In order to effectively prevent damage to the equipment caused by over-rolling of the belt, it is installed above a certain height in the reverse direction from the top to the bottom of the transport conveyor, so as to avoid difficulty in adjusting the meandering due to dropping of the transport. It relates to a reverse meandering device.

In general, ores and coals used as raw and fuel in blast furnace operations in steel mills are transported through transport conveyors from the unloading place of the ship to the yard of the factory. This phenomenon is caused by being transported to one side instead of being transported, which is caused by a piece of transport material loaded on the belt of the transport conveyor, that is, ore or coal is not loaded on the center portion of the transport conveyor belt. An adjusting device for adjusting the meandering of such a conventional transport conveyor is shown.

That is, as shown in Figure 1, when the transport object 130 is loaded through the chute on the belt 120 is orbitally transferred to the transfer line (P1) and the return line (P2) as the pulley 110, the belt The transport is transported by 120.

At this time, the U-shaped guide rolls for forming the conveying line (P1) of the belt is installed on the upper portion of the frame 140, the installation of the transport conveyor 100, the return line (P2) as the guide roll below The retainer belt 120 'is transferred, and the conventional meander adjusting device 150 is installed below the frame 140.

That is, the base 152 is installed so as to rotate left and right under the frame 140, and guide rolls 154 are installed at both sides of the base 152 to guide both edge portions when the return belt 120 ′ is meandered. In the center of the base 152, a feed roll 156 supporting the transfer of the belt 120 'is installed.

Accordingly, when meandering of the return belt 120 'occurs, the base 152 rotates in contact with one of the guide rolls 154 on both sides, and the feed roll 156 installed on the base 152 is inclined. The meandering of the belt 120 'is adjusted by supporting the return belt 120'.

However, as shown in Figure 2a, due to the moisture state of the transport material or the malfunction of the upper transport conveyor (P ') ore or coal as the transport is over-loaded on the aqueous line (P1) of the lower transport conveyor (100). The belt 120 and the return belt 120 'are meandered severely, and thus, a considerable amount of the transport object 130 dropped from the belt 120 falls to the meander adjusting device 1 on the lower side.

Therefore, as shown in FIG. 2B, the dropped transport object 130 meanders the return belt 120 ′ while interfering with the operation of the guide roll 154 and the feed roll 156 of the meander adjusting device 150. In the end, the return belt 120 'continuously meanders severely, but causes a safety accident to damage the base 152 and the guide roll 154 of the meander adjusting device 150.

However, the conventional meander adjusting device 150 has a base 152 on which the guide roll 154 is installed, which is installed under the frame 140 so that the guide roll 154 is pushed as the return belt 120 '. When the guide roll 154 cannot be afforded to one side, there are various problems such as the base 152 as well as being easily broken while colliding with the frame 140.

The present invention has been made in order to improve the various problems as described above, the object of the present invention is to install the meander adjustment device installed on the transport conveyor in the reverse direction from the upper side to the lower side of the frame, even if the belt overrun occurs In order to provide a free space of the guide roll for guiding the corner portion of the to provide a reverse conveyor meandering device of the transport conveyor to prevent the guide roll from being damaged while being pushed along with the transport.

In addition, another object of the present invention is that the meander adjusting device is installed on the frame in a reverse direction even if the overly stacked transport drops, thereby operating the transport of the guide roll and the conveying roll to substantially adjust the meandering of the return belt. An object of the present invention is to provide a reverse meandering device for a transport conveyor that can smoothly perform meandering by avoiding interference.
