Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a method for removing the furnace lid - coke guide - in the stopped state after stopping the running operation with the door lifter aligned with one kiln mouth. This invention relates to a coke guide vehicle that can complete a series of coke guide operations on a furnace lid.

(Problems of the Prior Art to be Solved by the Invention) In most conventional coke guide cars, during one coke guide operation, the entire coke guide car must be run twice to align the door lifter and guide cage with the kiln mouth. It becomes necessary. In this case, the weight of the coke guide wheel was extremely large as will be described later, and it was not possible to easily and quickly perform the above-mentioned centering of the furnace lid and cage alignment. In addition, the dust collection hood is fixed to the coke guide car so that it can be connected to the dust collection duct along the guide car rail connected to the dust collector in a cage-aligned state, and the coke guide car is connected to the coke guide car for centering the furnace lid. When the vehicle was running, it could not be connected to the dust collection duct, making it impossible to collect dust when removing the furnace lid. Furthermore, 1
The guide cage, door lifter, and other coke guiding work equipment, their power source, and control device are mounted on one truck, and the dust collection hood is fixed on the two trucks.Although the weight of the guide truck is extremely large, it is difficult to overcome wheel pressure limitations. Since the weight of the guide vehicle had to be the same or less than the weight of the existing guide vehicle, there was a limit to how many different types of vacuum cleaners could be installed.

Currently, there are fixed-position coke guide cars, but they still only have one trolley, and the weight of the guide car is extremely large, making it impossible to use them in existing furnaces.

(Objective of the Invention) The present invention was devised to solve the above-mentioned conventional problems, and the truck is divided into two parts, a main truck and a driver truck, and the equipment necessary for coke guiding work is mounted on the main truck. However, by mounting the driving power source and control device of the equipment on the driving truck, the wheel pressure limit can be dealt with by dispersing the weight of the guide car, and coke guiding work can be done easily and quickly by running only the main truck. The purpose of the present invention is to provide a coke guide vehicle which is capable of collecting dust from the time of removing the furnace lid to the completion of coke guide work by connecting a dust collection hood to the driving vehicle side. .
