AI Technical Summary
Technical Problem
The existing support structures for stokers, as described in Patent Document 1, are not optimized to handle the reaction forces from the driving units, leading to an overly complex and heavy structure due to the need for a large number of members.
Method used
A stoker support structure comprising a first frame, a support column, a second frame with reaction force receiving portions, and width-direction diagonal members that efficiently transmit and distribute loads, reducing the number of members required while maintaining strength.
Benefits of technology
The stoker support structure achieves weight reduction while effectively managing complex three-dimensional load fields, ensuring stability and strength through optimized load transmission.

Abstract
To provide stoker support structure which adapts to a three-dimensional complicated load field and furthermore can be reduced in the weight of the structure.SOLUTION: Stoker support structure is provided, supporting on a plurality of pedestals, a stoker having: a stoker main body having a fire grate combusting a combustion object while horizontally transporting it; and a drive portion which extends in a transportation direction of the combustion-object, and connected at one end of the drive portion to the fire grate, the stoker support structure comprises: a first frame extending in a horizontal direction, and supporting the stoker main body; a columnar support extending upward from a lower end arranged on the pedestal, and supporting the first frame; a second frame connected to the first frame in the transportation direction, and having a reaction force receiving portion supporting the other ends of a plurality of drive portions which are arranged in parallel in a width direction intersecting with the transportation direction; and a plurality of width-direction oblique materials extending while being inclined in such a manner that intervals between the oblique materials expand in a width direction as progressing upward from the lower end which is arranged on the pedestal.SELECTED DRAWING: Figure 2
