  There is a demand for weight reduction in a coke oven guide car that guides coke pushed out from the furnace opening of the carbonization chamber. For example, the guide wheel is often provided movably on a rail extending along a plurality of coking chambers arranged side by side. Guide cars can be subjected to horizontal loads during strong winds and earthquakes. Since the guide wheel has a hollow structure that forms a coke guide path, the guide wheel may be deformed particularly when a large load is applied in the rail extending direction.

  If a reinforcing member is added to suppress deformation due to a load in the horizontal direction, the guide wheel becomes heavier, which is against the demand for weight reduction. When the guide car becomes heavy, there is a problem that the manufacturing cost increases. Such a problem may occur not only in the guide wheel that moves on the rail but also in the guide wheel of the coke oven that moves by other means. For these reasons, the conventional coke oven guide car has a problem to be improved from the viewpoint of achieving both weight reduction and strength.

  An object of the present invention is to provide a guide car for a coke oven that can achieve both weight reduction and strength.

  In order to solve the above-described problems, a guide wheel according to an aspect of the present invention includes a cage that guides coke extruded by an extrusion ram from a carbonization chamber of a coke oven, in a first direction that intersects the movable direction of the extrusion ram.

In particular, since the beam member set 34 forms a lateral V-shaped structure, the beam member set 34 exhibits a high strength against a load input to the support frame 20 without blocking an opening for the guide path 14b.

[Second Embodiment]
Hereinafter, another example of the support frame 20 according to the second embodiment will be described with reference to FIG. 3. FIG. 3 is a side view schematically showing another example of the support frame 20 of the guide wheel 10 and corresponds to FIG. 2. This example is different from the second embodiment in that the third beam member 32 is provided, and the other configurations are the same. Therefore, the redundant description will be omitted, and the configuration different from the first embodiment will be mainly described.

  The support frame 20 according to the second embodiment further includes a third beam member 32 that connects the first beam member 28 and the second beam member 30 and extends in the Y-axis direction.

That is, the 3rd beam member 32c comprises the 1st beam member 28c, the 2nd beam member 30c, and the triangular structure 20q. The third beam member 32 may be formed of a shape steel such as H-shaped steel, and may be connected by a known connection means such as bolt fastening or welding.

  As shown in FIG. 3, the third beam member 32 forms a triangular structure 20p, 20q with the first beam member 28 and the second beam member 30, whereby the strength of the beam member set 34 can be further increased. Since the third beam member 32 forms a lateral A-shaped structure with the beam member set 34, the deflection of the upper frame 22 can be suppressed.

  Next, an overview of one embodiment of the present invention will be described. A guide wheel according to an aspect of the present invention is a guide wheel that includes a cage that guides coke extruded from a coking chamber of a coke oven by an extrusion ram, and is movable in a first direction that intersects the moving direction of the extrusion ram. The cage includes a support frame that supports a guide member that surrounds the movable extension of the extrusion ram and forms a guide path for the coke. The support frame includes an upper frame extending in the first direction on the upper side of the guide path, a lower frame extending in the first direction on the lower side of the guide path, a vertical frame connecting the upper frame and the lower frame, and an upper frame and a vertical frame. And a second beam member that connects the lower frame and the vertical frame. The first beam member and the second beam member are provided to be inclined with respect to the first direction and the vertical direction.

  According to this aspect, since the first beam member and the second beam member are included in the support frame, each frame forms a triangular structure, and the strength against a horizontal load in the event of strong wind or earthquake is improved.

  The first beam member and the second beam member may be connected to each other. In this case, since the first beam member and the second beam member form a laterally V-shaped structure, high strength is exhibited against a load in the horizontal direction.

  The connection region between the first beam member and the second beam member may be provided in the vicinity of the middle point in the vertical direction of the vertical frame. In this case, compared to the case where the connection region is close to one of the upper and lower sides, the triangular structure formed on the upper and lower sides can be made smaller, so that the strength against the load is improved as a whole.

  The support frame may further include a third beam member that connects the first beam member and the second beam member and extends in the vertical direction. In this case, since the third beam member constitutes a beam member set and a lateral A-shaped structure, the deflection of the upper frame 22 is suppressed.

  The support frame may include a plurality of beam member sets including a first beam member and a second beam member connected to each other. The plurality of beam member sets include a pair of beam member sets that are spaced apart from each other in the first direction across the guide path. In this case, compared with the case where only one beam member set is provided, the strength against a horizontal load in the event of strong wind or earthquake is improved.

  The pair of beam member sets may be arranged symmetrically. In this case, it is less likely to cause an imbalance in load bearing performance than in the case of asymmetric arrangement.

  In the above, it demonstrated based on each embodiment of this invention. Those skilled in the art will understand that these embodiments are illustrative, and that various modifications and changes are possible within the scope of the claims of the present invention, and that such modifications and changes are also within the scope of the claims of the present invention.
