Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coke oven address detection device that can reliably detect the address of a coke oven oven.

Generally, in the operation of a coke oven, there is a furnace kiln desorption device, an extruder equipped with a coke pushing ram, a charging coal leveling device, etc., a raw material coal charging car, a fire extinguishing truck loaded with red-hot coke, and a fire extinguishing truck. Coke oven moving machinery, such as a coke guide car that guides the red-hot coke, travels and stops in close communication along the furnace bank. The operation of these mobile machines is extremely complicated, which is why automatic operation is performed.

By the way, these mobile machines usually travel in oven clusters that are tens to hundreds of meters long, and they must stop at a predetermined position in front of the coke oven, but it is ensured that they stop in front of the coke oven at a predetermined location. It is necessary to accurately detect the address of the coke oven.

Conventionally, as shown in FIG. 1, address display code plates A1, A2, A3 have been used in which addresses 49, 50, 51, etc. are appropriately set in a coke oven, and numerical values corresponding to these addresses are displayed by a combination of number code plates. ,A4,
Sensors 2 installed on the side wall 1 of the coke oven and detecting the address display code plates A1, A2, A3, and A4 are installed on the coke oven moving machine 4 via the holding member 3 as shown in FIG. As the coke oven moving machine 4 moves, the sensor 2 detects the address display code plates A1, A2, A3, A4.
The address of a predetermined coke oven is detected by detecting the presence or absence of the coke oven.

However, if sensor 2 makes a detection error, it will detect a different address from the address of the coke oven it is passing through, and the coke oven moving machine will be stopped before a coke oven other than the designated one. There was a drawback.
