Description

  The present invention relates to an extruder for extruding coke in a carbonization chamber of a coke oven.

  An extruder for extruding coke in a carbonization chamber of a coke oven is known. For example, Patent Document 1 describes an extruder that extrudes coke by pushing an extrusion ram into a carbonization chamber.

And extrude coke.

JP 2014-051609 A

There is a demand for weight reduction in the extruder. In order to extrude coke efficiently, a strong pushing force may be applied to the extrusion ram that extrudes coke in the carbonization chamber. When the extrusion ram is extruded, the support structure that supports the extrusion ram receives a large reaction force in the direction opposite to the pushing force. When receiving a large reaction force, the support structure may be deformed. Further, it is desirable that the support structure has a strength that can withstand a horizontal force in a strong wind or an earthquake. If a reinforcing member is added to the support structure in order to suppress deformation due to this reaction force or horizontal force in the event of an earthquake, the extruder becomes heavy, contrary to the demand for weight reduction. Moreover, when an extruder becomes heavy, there also exists a problem of manufacturing cost increasing.
Therefore, the conventional extruder has a problem to be improved from the viewpoint of achieving both weight reduction and strength.

  An object of the present invention has been made in view of such problems, and is to provide an extruder capable of achieving both weight reduction and strength.

  In order to solve the above-described problems, an extruder according to an aspect of the present invention supports an extrusion ram that is taken in and out in a first direction with respect to a coking chamber of a coke oven, and moves in a second direction that intersects the first direction. A possible extruder is provided with a first support structure for supporting an extrusion ram so as to be movable in a first direction. The first support structure includes an inclined beam member provided to be inclined with respect to the first direction and the second direction in plan view.

In the example of FIG. 3, the third inclined beam member 46 includes two types of third inclined beam members 46 b having different inclination directions. These third inclined beam members 46b constitute a V-shaped structure upside down.

  Next, the mechanism by which the extruder 10 exhibits high strength will be described with reference to FIGS. When the power source rotates, power is transmitted to the extrusion ram 54 via the pinion gear of the power source and the rack teeth of the extrusion ram 54, and the push ram 54 receives a pushing force in the X-axis direction. When the pushing ram 54 receives the pushing force, the pushing force reaction force F is inputted to the first support structure 20. In the example of FIGS. 2 and 3, a reaction force F in a direction away from the carbonization chamber 52 is input to the first support structure 20 in the region indicated by the symbol E. The region indicated by the symbol E is a region where the pedestal that receives the extrusion reaction force is fixed to the first support structure. The pedestal that receives the extrusion reaction force is, for example, a pinion frame. In the example of FIG. 2, the reaction force F is in the vicinity of the apexes of the first beam member 22 and the inclined beam member 28 having a triangular structure composed of the first beam member 22, the erected beam member 26 c and the inclined beam member 28. Is input. In this case, the stress applied to these beam members is mainly compressive stress or tensile stress, and these beam members exhibit high strength against the extrusion reaction force.

  In the example of FIG. 3, the reaction force F is a triangular structure composed of the second beam member 24, the leg member 12, and the second inclined beam member 42b, and the second beam member 24 and the second inclined beam member 42b. Input in the vicinity of the vertex in the X-axis direction. In this case, the stress applied to these beam members is mainly compressive stress or tensile stress, and these beam members exhibit high strength against the extrusion reaction force. These beam members exhibit high strength by a similar mechanism against strong winds and horizontal forces in the event of an earthquake. In the example of FIG. 3, the third inclined beam member 46 b forms a triangular structure with the leg member 12 and the second floor structure 32, and can increase the strength against the horizontal force during strong winds and earthquakes.

  Next, an overview of one embodiment of the present invention will be described. An extruder according to an aspect of the present invention is an extruder that supports an extrusion ram that is taken in and out in a first direction with respect to a coking chamber of a coke oven and is movable in a second direction that intersects the first direction. A first support structure is provided that supports the extrusion ram so as to be movable in the first direction. The first support structure includes an inclined beam member provided to be inclined with respect to the first direction and the second direction in plan view.

  According to this aspect, compared to the case where the first support structure does not include an inclined beam member, the inclined beam member resists the extrusion reaction force of the extrusion ram, strong wind, and horizontal force during an earthquake, thereby suppressing the deformation of the extruder. can do. For this reason, weight reduction is realizable, ensuring the intensity | strength of an extruder.

  The inclined beam member may include a pair of inclined beam members that are spaced apart in the second direction across the extrusion ram, and the distance between the pair of inclined beam members may be configured to increase as the distance from the carbonization chamber increases. In this case, when receiving the extrusion reaction force of the extrusion ram, the force can be smoothly transmitted from the inclined beam member 28 to the leg member 12 and from the leg member 12 to the ground.

  A leg member that extends in the vertical direction and is connected to the first support structure, and a second slope that is inclined with respect to the first direction and the vertical direction in a side view and connects the first support structure and the leg member. And a beam member. In this case, since the second inclined beam member forms a triangular structure with the first support structure and the leg member, the strength of the side surface of the apparatus against the extrusion reaction force of the extrusion ram is improved.

And may be further provided. In this case, since the third inclined beam member constitutes a floor structure, a first support structure, and a triangular structure, the strength of the side surface of the extruder against the extrusion reaction force of the extrusion ram is improved.

  A plurality of first support structures may be provided. In this case, since the extrusion reaction force of the extrusion ram can be divided and supported by the plurality of first support structures, the strength is further improved.

  The plurality of first support structures may include a pair of first support structures arranged symmetrically with the extrusion ram interposed therebetween. In this case, since the pair of first support structures support the extrusion ram symmetrically, generation of unnecessary moments can be suppressed as compared to the case of asymmetric support.
