    WHEEL APPARATUS WITH MEANS FOR MOVING IN BENT RAIL}
    [15] The present invention relates to a wheel device capable of traveling on a rail curved surface, and more particularly, to obtain a coke product, a high temperature by burning a fire from the bottom of the underjet system and transferring the radiant heat from the window to the carbonization chamber. The present invention relates to a wheel device capable of traveling on rail curved surfaces for repairing aged equipment generated in the process of producing high-strength coke after the air is cut off and the gas is burned with a heat source for a considerable time.
    [16] In general, as shown in Figure 2, the wheel device running on the rail is a running rail 80 to move the maintenance facility, the rail wheels (60a, 60b) inserted and rotated therein, the rail wheel (60a, 60b) attached to the door car 33 is moved, the wheel device 50 is attached to the lower portion of the door car 33 is moved along the running rail 80, and connected to the door car 33 Connection structure 51, the battery 20 is located on the side thereof to supply power, the lower panel 130 is provided with a built-in hydraulic motor on one side of the battery 20, and the lower panel 130 The driving lever mechanism 40 installed on one side of the upper side, the guide wheel 73 installed on both lower sides of the battery 20 and movable, and the guide rail 70 for preventing the door car 33 from being separated. ), And the limit switch 30 to prevent the upward of the door car 33.
    [17] The wheel device that runs on the rail configured as described above is supplied with power by the battery 20, and accordingly, when the hydraulic motor built in the lower panel 130 is operated, the drive attached to the upper portion of the connection structure 51 is performed. The wheel device 50 is moved.
    [18] As the travel wheel device 50 moves, the door car 33 and the rail wheels 60a and 60b attached thereto move along the travel rail 80.
    [19] By the way, the wheel device traveling in the conventional rail is a driving wheel made of a round urethane material installed on the top of the door Serbiscar because the height of the running rail is changed due to the shrinkage and expansion of the running rail installed on the aged equipment by the temperature difference of the coke oven The door car does not run because it is not rubbing, and thus, the operation of the coke carbonization chamber has been stopped, and problems of production stoppage have occurred. Also, the outflow of gas caused by the inability to quickly maintain the open door causes the maximum pollution of the coke oven. As a result, many problems have arisen in pleasant coke operation.
    [20] In order to solve the above problems, the present invention is a running rail of the urethane material in the running rail installed in the upper front of the carbonization chamber to maintain a constant pressure under any conditions with the running rail is friction with the running rail is made left and right driving The work table is raised by the hydraulic motor installed inside the panel to solve the conventional inefficient work factors, and the operator directly rides on the door car to move up, down, left and right on the work table more quickly and safely so that aging By repairing the facility and repairing the open door, it prevents the outflow of gas beforehand and provides a comfortable coke operation, and also provides a wheel device that can run on a rail curved surface that can prevent a collision with a moving vehicle. There is a purpose.
