Referring to the operation of the present invention made in the above configuration in detail as follows.

2 to 6, the chute 110 is installed in a section for changing the transport path between the conveyor (100, 120) for transporting the transport (M), such as ore and coal in the steel mill The opening and closing device 1 of the conveyor shuttle chute opening of the present invention, which opens and closes the opening tool 112 according to the movement of the adjacent shuttle and prevents safety accidents such as a worker's falling accident and the like, increases the safety of the equipment.

On the other hand, Figure 6 shows the operation step of the chute opening and closing device 1 of the present invention will be described the operation of the present invention based on Figures 2 and 6.

First, as shown in FIG. 6A, when the shuttle 130 adjacent to the chute 110 moves forward, that is, toward the chute side, the shuttle frame 134 is in contact with the contact arm 52 of the device 1. When the contact arm 52 is rotated counterclockwise, the operating shaft 50 through which the contact arm 52 is connected and passes through the fixed block 30 on the opening and closing plate 10 is fixed block opening 30a (Fig. 3) a second working piece (90), which is rotated within and is connected to the other end of the protruding piece (56), while being caught by the second fixing jaw (34) of the fixing block (30) while pulling the spring (54). The second operating piece 90 is lifted while contacting the contact member 92 of

Therefore, as soon as the second operating piece 90 is separated from the fixing block 30, the shuttle frame 134 moves forward and pushes the opening and closing plate 10, as shown in FIG. 6B, to open the chute opening 112. The opening and closing plate 10 in the sealed state is moved to one side of the chute 110.

As shown in FIG. 1, in the state where the shuttle 130 pushes the opening / closing plate 10, the feeding roll 104 is driven to rotate through the chute opening 112 to chute through the conveyor belt 100. The transport object M dropped in the 110 is transported through the lower conveyor 120 while the transport path is changed.

Next, as shown in FIG. 6C, when the chute drop of the consignment is completed and the shuttle 130 returns to its initial position (for example, the shuttle 130 moves due to maintenance work of the conveyor 100). When the shuttle 130 is moved and the chute 110 opening 112 is open due to a factor, the first operation piece 70 installed on the frame 134 side of the shuttle 130 is caused by its own weight. The shuttle 130 moving backward while being fixed to the fixed block first fixing jaw 32 on the opening and closing plate 10 moves the opening and closing plate 10 integrally.

Next, as shown in Figure 6d, the shuttle 130 is moved to the lower side of the first operating piece 70 is caught on the first fixing jaw 32 of the fixed block 30 on the installation frame 12 When the second operating piece 90 enters therebetween, the first operating piece 70 is lifted by the second operating piece 90 and is separated from the first fixing jaw 32 of the fixing block 30. As a result, only the shuttle 130 is moved.

At this time, the shuttle frame 134 which was in contact with the contact arm 52 is spaced apart, so that the protruding piece 56 rotates with the elastic force of the spring 54, and eventually the contact member 92 of the second operating piece 90. Since the protruding piece 56 is not in contact with the second working piece 90, the second working piece 90 stops the movement of the opening and closing plate 10 while being fixed by being caught by the second fixing jaw 34 of the fixing block 30 by its own weight. When the shuttle 130 moves again, the forward and backward movements of the opening and closing plate 10 are repeated, and the chute opening 10 is always opened only when the package drops to the opening and closing plate 10, and when there is no chute falling of the transportation object. The chute opening 112 is sealed to prevent safety accidents such as falling of the operator.

Accordingly, according to the present invention, the conveyor shuttle chute opening / closing device 1 opens the chute only when the cargo is dropped through the chute, and the chute opening 112 is completely opened by the movement of the shuttle 130. It is sealed by the opening and closing plate 10 to completely prevent the accident of the worker.

As described above, according to the present invention, the conveyor shuttle chute opening and closing device is adjacent to the chute for changing the transportation path in the conveyor facility for transporting ore and coal, which are raw materials and fuels used in the blast furnace operation in the steel mill, to the factory. By opening and closing the chute opening automatically according to the movement of the installed conveyor shuttle, it is to provide an excellent effect to improve the safety of the facility by preventing the accident of falling through the chute opening in advance.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of this can easily know.
