Description

{Carrier-car collision avoidance apparatus}

The present invention relates to a conveyor collision avoidance apparatus, and more particularly, to a conveyor collision avoidance apparatus capable of preventing a collision between conveyors sliding on a path.

In general, a loading / unloading crane (hereinafter referred to as a conveyor) is used to unload a raw material (fuel) to a desired position while moving along a rail installed on a ceiling in a steelworks or a power plant. Various types of raw materials In order to shorten the operating time, each of the plurality of conveyors is driven by the operator and the raw material (fuel) is transported by sliding on the same rail.

In this case, if the movement distance of the conveyors due to the abnormal weather occurs due to lack of attention during operation of the operator and drowsy operation of the operator, or if the operator does not make a mistake, There arises a problem that they collide with each other.

In other words, when the driver can not look back the conveyors when controlling the conveyors and can not predict the close state between the conveyors sharing the same path, the collision with the conveyor disposed forward or rearward of the conveyor in operation Can occur.

In this way, when the collision of the conveyors on the rails occurs due to the external factors, there occurs a problem that the conveyors fall off the rail and fall down to the ground, and the worker on the conveyor falls due to the fall of the conveyor, It can cause accidents.

In addition, the conveyors that collide with each other are damaged due to the collision impact, so that it takes time and cost to repair them. In addition, since the raw material (fuel) being conveyed through the conveyor keeps the state during normal conveyance In the worst case, it is difficult and can cause the earth workers to fall into the ground and cause human casualties.

If such a problem can not prevent the collision of the conveyors, the efficiency of the operation and the productivity will be reduced because the operation of the feeder conveying the raw materials (fuel) must be stopped.
