Description

Central suit damper adjuster of belt conveyor {AN APPARATUS FOR ADJUSTING THE DAMPER OF CETRAL CHUTE IN BELT-CONVEYOR}

The present invention relates to a device for adjusting the damper of the central chute provided in the belt conveyor, and more specifically, to the light attached to the transport in the central chute connecting the upper and lower belt conveyors, which are transport facilities for transporting soft and raw materials. The present invention relates to a central chute damper adjusting device for a belt conveyor that can prevent malfunction and failure of the damper.

In general, a facility for transporting soft and raw materials (hereinafter, referred to as "transport") used in steel mills is a belt conveyor that circulates the belt member in an endless track by a driving source (not shown) as shown in FIG. 120a) (120b) 120c is used to transfer to the destination. In the long and short distance transfer, several belt conveyors (120a) (120b) (120c) are combined with each other to form a single transport line.

On the other hand, the upper belt conveyor (120a) and the lower belt conveyor (120b, 120c) can be connected from a straight line 90 ° or other various angles, the upper chute 110 is a medium of the upper belt conveyor (120a) The lower belt conveyor (120b) (120c) is provided with a lower damper 113 that is movable by the screw member (113a) so as to smoothly drop the supply to the lower side belt conveyor (120b) ( It rests on 120c) to prevent knitting and meandering.

Then, between the upper chute 110 and the lower side belt conveyor (120b) (120c), as shown in Figures 2 and 3, the lower side is provided with a transport falling from the upper side belt conveyor (120a) The central chute 140 is configured by a branch chute 141 of the "Ｙ" shape so as to selectively fall to one of the two belt conveyors (120b, 120c).

In addition, the central chute 140 is connected to the rotating shaft 143 which is rotated in the forward and reverse directions by the rotational driving force of the motor member 145 through a power transmission means such as a belt 148 to determine the drop flow path. The rotary shaft 143 includes a central damper 142 which is pivotally operated to selectively open and close the flow path of the branch chute 141.

In the branch chute 141 of the conventional central chute 140, the attachment light is mainly fixed to the inner wall of the intersection point where the upper and lower flow paths meet each other due to the moisture content of the transport object falling therethrough and the component characteristics thereof, as shown in FIG. As described above, even when the motor member 145 is driven to select one of the lower side belt conveyors 120b and 120c, the central damper may be formed by the attachment light fixed to the branch chute 141. It was difficult to turn the cargo of 142 so that the change of the line of the cargo could not be performed in a timely manner.

The pivoting operation of the central damper 142 is performed by remotely controlling the rotational driving of the motor member 145. Even if the sensor of the motor member 145 is tripped or a trouble occurs due to fixing, the central chute 140 The driver who is hard to grasp the internal situation of the) operates several times after the release of the trouble, which may cause damage to the equipment such as the motor member, and thus the equipment operator maintains the situation inside the upper chute 110 to the field worker when selecting the line. After requesting confirmation via wireless, it was operated.

However, it is difficult for one worker to check several central suits 140 and must move a large area, thereby causing a large work load of the worker and reducing work efficiency. In particular, when attachment light is generated on the wall surface of the central chute 140 to make it difficult to turn the central damper 142, the worker stops the transport operation to drop the attachment light in the dark and narrow height area. Since it has to be carried out over a long period of time in one state, there is a problem that the risk of safety accidents is very high, and the facility operation time is long and the facility operation rate is lowered.

In FIG. 1, reference numeral 129 denotes a lower chute, 146 denotes a protruding jaw that protects the front end of the central damper 142 from a dropping supply, and 145a denotes a driving pulley of the motor member 145.

Therefore, the present invention has been proposed to solve the conventional problems as described above, the object of which is to turn the integral light with the damper to the part where the attachment light is attached to the wall surface of the central chute for switching the transport path of the upper and lower conveyor belt. It is to provide a central chute damper adjustment device of the belt conveyor that can be adjusted to prevent the fixing of the attachment light, to eliminate the removal of the attachment light to improve the equipment operation rate, and to prevent safety accidents.
