2. Description of the Related Art Red-hot coke made by carbonization of coal is
It is necessary to cool to a temperature that does not hinder handling. As equipment for cooling such red hot coke to a low temperature, there is coke dry fire extinguishing equipment. When the red hot coke is cooled by this coke dry fire extinguishing equipment, the red hot coke is received from the coke oven via the guide car to the coke bucket on the bucket carrier.

Then, the bucket carrier is moved in the same direction as that of the guide car and moved to a position where the hoisting machine stands by, and the coke bucket on the bucket carrier is guided along the guide rail by the hoisting machine. Wind up vertically. Next, move the hoist with the coke bucket suspended horizontally, position the coke bucket above the fire extinguisher tower of the coke dry fire extinguisher, and open the discharge port at the bottom of the coke bucket to extinguish the red hot coke. Charge the fire extinguisher from the tower entrance.

By the way, with the increase in the size of coke dry fire extinguishing equipment, it is required to shorten the cycle of red hot coke transportation from the coke oven to the coke dry fire extinguishing equipment and to improve the bucket lifting speed. Positioning the guide rail for hoisting the coke bucket in the middle portion of the coke oven cluster is an effective means for satisfying these requirements.

However, with such an arrangement,
There is a problem that the guide rails for hoisting the coke bucket hinder the travel of the guide vehicle. In order to solve the above-mentioned problems, conventionally, the following method of retracting the lower guide rail of the guide rail has been adopted.

(1) Guide Rail Flipping-Up Method As shown in FIG. 3, the guide rails used when hoisting the coke bucket 22 mounted on the bucket carrier 21 are a lower guide rail 24a and an upper guide rail 24b. A wire 27 connected to the lower guide rail 24a via a pulley 25 by using a winch 26.
Then, while lowering the lower guide rail 24a even turning in a direction orthogonal to the traveling direction of the guide wheel 28,
Make sure that it does not interfere with the travel of the guide vehicle 28.

(2) Horizontal guide rail movement system As shown in FIG. 4, the guide rails used when hoisting the coke bucket 22 mounted on the bucket carrier 21 are the lower guide rail 34a and the upper guide rail 34b. In the guide rail carriage 29, the lower guide rail 34a is horizontally moved in a direction orthogonal to the traveling direction of the guide vehicle 28 so as not to interfere with the traveling of the guide vehicle 28.

(3) Vertical guide rail movement system As shown in FIG. 5, the guide rails used when the coke bucket 22 mounted on the bucket carrier 21 is hoisted by the hoist 23 are a lower guide rail 44a and an upper guide rail 44b. Use winch 30 and pulley 31
32 connected to the lower guide rail 44a via
Then, vertically move the lower guide rail 44a upward,
Make sure that it does not interfere with the travel of the guide vehicle 28. In addition, the code | symbol 33 in FIGS. 2-5 is a coke oven.

[0009]

However, the conventional lower guide rail retracting method described above has the following problems. (1) Guide rail splash-up method The stroke is large and it takes time to retract. The drive is expensive. It lacks stability as a guide rail because there is no support at the lower end of the guide rail.

(2) Horizontal guide rail movement system: Equipment and power costs are high. It lacks stability as a guide rail because there is no support at the lower end of the guide rail. There is a need for a device that prevents the guide rails from moving horizontally when a horizontal force is applied.

(3) Vertical guide rail movement system In addition to the same problems as the guide rail flip-up system, dust may be trapped in the slide portion.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and the guide rails can be easily retracted without the need for large-scale equipment, and the coke dry fire extinguishing which is becoming larger in size in recent years. It is an object of the present invention to provide a hoisting tower guide rail for coke dry fire extinguishing equipment that can shorten the cycle time required for the equipment and improve the bucket lifting speed.

[0013]

According to the present invention, in a hoisting tower guide rail for coke dry fire extinguishing equipment, the guide rail is moved away from the coke oven in a direction orthogonal to the traveling direction of the guide car with the upper portion of the guide rail as a fulcrum. A hoisting tower guide rail for a coke dry fire extinguishing facility, which is configured to swivel in any direction, and includes a hydraulic cylinder that swivels the guide rail, and a hydraulic cylinder that fixes the lower end of the guide rail. .

[0014]

According to the present invention, the guide rail is rotated from the use position to the retracted position and vice versa by revolving the guide rail around the upper part of the guide rail in the direction orthogonal to the traveling direction of the guide car. Or you can move. For this reason,
The travel stroke of the guide rail is short, and
The time required for this operation is also small and the coke transportation time can be greatly shortened. At the same time, since the retreat or movement is performed by turning, the mechanism is simple and the equipment cost can be greatly reduced. Then, the fixing hydraulic cylinder can surely fix the lower portion of the guide rail so as not to move.
