JP, 2014-051609, A

There is a demand for weight reduction of the extruder. In order to extrude coke efficiently, strong pushing power may be applied to the extrusion ram which 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 its pushing power. If a large reaction force is received, the support structure may be deformed. In addition, it is desirable that the support structure has a strength that can withstand horizontal forces in high winds and earthquakes. If a reinforcing member is added to the support structure in order to suppress the deformation due to the reaction force or the horizontal force at the time of an earthquake, the extruder becomes heavy, which is contrary to the demand for weight reduction. In addition, when the extruder becomes heavy, there are problems such as an increase in manufacturing cost.
From these reasons, the conventional extruder has a problem to be improved in terms of achieving both weight reduction and strength.

  The object of the present invention is made in view of such a subject, and is providing an extruder which can aim at coexistence of weight reduction and intensity.

A possible extruder comprising a first support structure for movably supporting an extrusion ram 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 a plan view.

These third inclined beam members 46 b constitute a V-shaped structure upside down.

  Next, with reference to FIG. 2 and FIG. 3, the mechanism by which the extruder 10 exhibits high strength will be described. When the power source rotates, power is transmitted to the extrusion ram 54 through the pinion gear of the power source and the rack teeth of the extrusion ram 54, and receives push output in the X-axis direction. When the pushing ram 54 receives the pushing output, the reaction force F of the pushing output is input to the first support structure 20. In the example of FIG. 2 and FIG. 3, the reaction force F in the direction away from the carbonization chamber 52 is input to the first support structure 20 in the region indicated by the symbol E. An area indicated by a symbol E is an area where the pedestal receiving the pushing reaction force is fixed to the first support structure. The pedestal that receives the pushing reaction force is, for example, a pinion mount. In the example of FIG. 2, the reaction force F is in the vicinity of the vertex of the first beam member 22 and the inclined beam member 28 in a triangular structure configured by the first beam member 22, the bridge beam 26 c and the inclined beam member 28. Is input to In this case, 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 constituted by the second beam member 24, the leg member 12 and the second inclined beam member 42b, and the reaction force F is the same as that of the second beam member 24 and the second inclined beam member 42b. It is input near the vertex in the X-axis direction. In this case, 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 also exhibit high strength by the same mechanism against horizontal force in high winds and earthquakes. Moreover, in the example of FIG. 3, the 3rd inclination beam member 46b can comprise the leg member 12 and the 2nd floor structure 32 and a triangular structure, and can raise the intensity | strength with respect to the horizontal force in the case of a strong wind or an earthquake.

The first support structure includes an inclined beam member provided to be inclined with respect to the first direction and the second direction in a plan view.

  According to this aspect, compared with the case where the first support structure does not include the inclined beam member, the inclined beam member resists the extrusion reaction force of the extrusion ram, the strong wind, the horizontal force at the time of earthquake, and suppresses the deformation of the extruder. can do. For this reason, weight reduction can be realized while securing the strength of the extruder.

It may be connected to any of the beam members. In this case, since the inclined beam member forms a triangular structure with the first beam member, the second beam member, and the bridge beam member, the strength against the extrusion reaction force of the extrusion ram is improved.

  The inclined beam member may include a pair of inclined beam members spaced apart from each other in the second direction with the extrusion ram interposed therebetween, 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 the extrusion reaction force of the extrusion ram is received, the force can be smoothly transmitted in the order from the inclined beam member 28 to the leg member 12 and from the leg member 12 to the ground.

  A leg member extended in the vertical direction and connected to the first support structure, and a second inclination that is provided to be 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, the second inclined beam member forms a triangular structure with the first support structure and the leg members, so that the strength of the side surface of the apparatus against the extrusion reaction force of the extrusion ram is improved.

In this case, since the third inclined beam member constitutes a triangular structure with the floor structure and the first support structure, the strength of the side surface of the extruder with respect to the extrusion reaction force of the extrusion ram is improved.

  A plurality of first support structures may be provided. In this case, since the pushing reaction force of the pushing ram can be separately 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 about the extrusion ram. In this case, since the pair of first support structures support the extrusion ram in a symmetrical manner, generation of unnecessary moment can be suppressed as compared with the case of asymmetric support.
