      The present invention relates to an apparatus for preventing the chain of the reversing winch to sag downward in the coke oven installation, and more particularly is to be pulled by the cylinder of the reversing winch to open and close the air supply box and the waste stool. Prevents the lower chain deflection of the gel chain (Gall Chain) to prevent uneven wear of the gel chain and the sprocket wheels, thereby increasing the durability and increase the life of the equipment, as well as the stable operation of the coke oven equipment combustion efficiency A chain guide for a reversing winch of a coke oven that has been improved to significantly increase the work load and significantly improve work productivity.

      In general, a coke oven equipped in an ironworks is provided with 75 individual combustion chambers 112 per battery of the coke oven 100, as illustrated in FIG. (Not shown) and the air supply box 120, and the waste stool 130, the waste gas burned in the combustion chamber 112 is discharged to the outside is formed in pairs.

     In the coke oven 100, the combustion chambers 112 are arranged in an even and even direction in the longitudinal direction of the coke oven 100, and alternately every 20 minutes with the even-numbered combustion chambers 112 and even-numbered combustion chambers ( 112 are alternately combusted, and fuel gas and air are used as heat sources in the combustion chamber.

      In addition, the coke oven 100 has a reversing winch 140 for opening and closing the air supply box 120 and the waste valve 130 every 20 minutes so that air is smoothly supplied to the combustion chamber 112 and exhaust gas is exhausted. The reversing winch 140 is a hydraulically operated cylinder 145 is located in the middle of the first floor of the coke oven (100).

      The reversing winch 140 is connected to the pull rods 150 through the gel chain 147 to the left and right of the cylinder 145, and a separate connection chain 155 to the pull rod 150. ) As the air supply box 120 and the waste side 130 is connected to each of the 75 is moving.

      A hydraulic device (not shown) for operating the cylinder 145 is composed of a conventional hydraulic tank, a hydraulic pump, a motor, various valves, and an electric device for control, and they operate the cylinder 145 at regular intervals. To supply fuel and air to the combustion chamber 112 of the coke oven 100 and to discharge the waste gas.

      The air supply for combustion in the coke oven 100 is made by opening and closing a plurality of air supply box 120 provided on one side of the coke oven 100, the waste gas after combustion is discharged to the outside through the waste stool 130. .

      The coke oven 100 alternately replaces the air supply box 120 and the waste valve 130 with odd numbers 1,3,5 to 71,73 and even numbers 2,4,6 to 72,74. 20 minutes by changing the operation, the cylinder 145 of the reversing winch 140 is operated to pull or push the pull rods 150 through the gel chain 147, respectively connected to the pull rod 150 The air supply box 120 and the waste valve 130 are opened and closed through chains 155.

     The reversing winch 140 is a gel chain 147 connecting the cylinder 145 and the pull rod 150 is disposed on the four corners of the coke oven 100, respectively, sprocket wheel (Sprocket Wheel) (160) It is supported by the rotatable by the operation of the cylinder 145 is to pull or push the pull rod 150.

      However, since the gel chain 147 is a heavy object and the pull rod 150 connected thereto is also a heavy object, deflection to the lower side is caused by the weight of the sprocket wheel 160 and the gel chain 147. Local wear occurs, and uneven wear occurs in the fastener 152 connecting the gel chain 147 and the pull rod 150.                         

      Such uneven wear shortens the life of the gel chain 147 and the fasteners 152 more than their normal life, leading to premature failure, and thus, stops the operation of the coke oven 100 and requires rapid maintenance. It is.

      In addition, this conventional problem also affects the operation rate of the coke oven equipment, resulting in a decrease in work productivity.

      Therefore, in order to solve this problem, it is required that the gel chain 147 is kept horizontal and does not cause sag, and does not generate uneven wear to the sprocket wheel 160.

      The present invention is to solve the conventional problems as described above, the purpose is to prevent the wear of the sprocket wheel or gel chain by moving the gel chain always horizontally to prevent the wear of the gel chain and gel chain fasteners, etc. It is to provide a chain guide device for the reversing winch of the coke oven so as to minimize maintenance work in the combustion control system of the coke oven.

In addition, the present invention provides a smooth access to the air supplied to the combustion chamber of the coke oven and the waste gas discharged from the combustion chamber, thereby improving the efficiency of the coke oven and the improvement of the work productivity of the coke oven reversing To provide a chain guide device for the winch.

In order to achieve the above object, the present invention, in the guide device of the chain used in the reversing winch for achieving the exhaust operation of the air supplied to the combustion chamber in the coke oven equipment, and the exhaust gas discharged from the combustion chamber,
