Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:

in the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As shown in fig. 1, in the conventional technology, a power rod 1 is driven to rotate by manpower, so as to drive a power shaft 2 to move, and a furnace door is driven to rotate by the movement of the power shaft 2;

as shown in fig. 2, the technical solution of the present invention is:

a transmission mechanism for repairing a furnace door of a coke furnace door repair station comprises a power shaft 2 for driving the furnace door to realize rotary motion and a power rod 1 for providing torque force for the power shaft 2; the power lever 1 includes:

a small chain wheel 1-1 fixed at the end of the power shaft 2;
