IQ] The present invention has been made in view of the above problems, and allows accurate running even when the running rail inside a bit formed underground is not completely exposed on the ground surface. [Function] In the fixed position stopping device for a coke oven working machine according to the present invention, the body frame is stopped running with respect to the running rail, and then a trolley is used to adjust the relative position with the oven opening. In order to fix the vehicle to the running rail, a brake magnet such as an electromagnet is used. Therefore, since the braking force can be applied to the top of the running rail, the braking function can be reliably exerted even if the running rail is disposed inside the bit.

Furthermore, when the brake function is not required, the brake magnet can be separated from the travel rail by an elastic member such as a compression coil spring, thereby allowing the body frame to travel.

[Embodiment] Next, a fixed-position stopping device 10 for a coke oven working machine according to an embodiment of the present invention will be described based on FIGS. 1 to 3. However, the same parts as in FIGS. 4 and 5 are given the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 is a perspective view of a fixed position stopping device 10 for a coke oven working machine, in which a pair of running errands 112 and a fixed position stopping device 10 are respectively attached to a pair of transverse frames 11 of a body frame 2.

The body frame 2 runs along the coke oven by running wheels 12 on a first running rail R1 and a second running rail R2.

Since the fixed position stop devices 10 on the left and right running rails R1 and R2 (hereinafter referred to as running rails R) are the same, only one will be described below.

FIG. 2 is a side view of the fixed position stop device 10 for a coke oven working machine seen from a position perpendicular to the running direction, and FIG. 3 is a front view of the same as seen from the running direction, showing the lower part of the machine frame 2 A truck 3 is attached to the body frame 2 so as to be movable relative to the body frame 2.
