本考案は、ウオーキングビーム式加熱炉において、固定
ビームを固定炉床上に支持する固定ポストの据付構造に
関するものである。[Detailed Description of the Invention] The present invention relates to an installation structure for a fixed post that supports a fixed beam on a fixed hearth in a walking beam heating furnace.
図面に従い本考案の一実施例を説明すると、第１図にお

している固定ポストを示す。An embodiment of the present invention will be described with reference to the drawings. In Fig. 1, 1 is a fixed hearth, and 2 is a burner mounted in the form of a gate on the fixed hearth for blowing out the flame of the burner 3 into the furnace. wall, 4
indicates a fixed beam, and 5a to 5d indicate fixed posts that horizontally support the fixed beam.

つき説明するようにコロを介して固定ビーム４の長手方
向に摺動自在にバーナ取付壁２の上面に支持されている
。A fixed post 5a supporting the middle part of the fixed beam 4,
The lower end of 5b is fixed on the fixed hearth 1 by bolts or welding, and the lower ends of the fixed bosses 5C and 5d that support both ends of the fixed beam 4 will be explained below with reference to FIGS. 2 to 4. It is supported on the upper surface of the burner mounting wall 2 via rollers so as to be slidable in the longitudinal direction of the fixed beam 4.
即ち、バーナ取付壁２の上面に平板６をボルト又は溶接

れた座板９を該コロ７上に摺動自在に乗載支持する。That is, a flat plate 6 is horizontally fixed on the upper surface of the burner mounting wall 2 by bolts or welding, and a plurality of rollers 7 are arranged on the flat plate 6 so as to be rotatable in a frame-shaped spacer 8, and fixed. A seat plate 9 fixed to the lower ends of the bosses 5C and 5d by welding is slidably supported on the roller 7.

中に冷却水を循環供給するための通水管である。10 is a stopper welded on the flat plate 6 to limit the amount of movement of the seat plate 9, and 11 is a fixed post (5C, 5d) that supports both side edges of the seat plate 9 so as to be able to slide from its upper surface to prevent falling. The side rails 12 are water pipes for circulating cooling water into the fixed posts and fixed beams.
このように構或された固定ポストの据付では、固定ビー
ム４が炉内の高温度によって熱膨張した場合その長手方
向の伸縮をコロ７が転動することによって吸収すること
ができる。In the installation of the fixed post constructed in this manner, when the fixed beam 4 thermally expands due to the high temperature inside the furnace, the expansion and contraction in the longitudinal direction can be absorbed by the rolling of the rollers 7.
従来ウオーキングビーム式加熱炉の固定ポストは熱膨張
により曲がりと反対向の冷間曲げを施して固定ビームの
熱膨張による変形を逃がすようにしていたが、これは加
工費が高く、特に固定ポストの直径が大きい場合とか、
実施例に示したようにバーナ取付壁の上面に支持させる
ことで固定ポストの長さが短かい場合には、固定ビーム
の伸びを吸収しきれない欠点があって固定ポストに過大
な熱応力が繰り返し負荷すると被熱物の衝撃的荷重によ
って破損をまねく惧れもあった。Conventionally, the fixed post of a walking beam heating furnace was cold bent in the opposite direction to the bending due to thermal expansion to release the deformation caused by the thermal expansion of the fixed beam, but this was expensive, especially for the fixed post. If the diameter is large,
As shown in the example, if the length of the fixed post is short by supporting it on the top surface of the burner mounting wall, there is a drawback that it cannot absorb the elongation of the fixed beam, and excessive thermal stress is applied to the fixed post. There was also a fear that repeated loading could lead to damage due to the impact load of the heated object.
しかるに本考案によれば、コロを介して固定ポストを支
持したことによってこのようは応力は完全に解消される
ので熱膨張を原因とする破損事故の発生は抑れられ安全
性が高いため、固定ポストに従来より直径の細いものを
使用することも可能となるなど非常に有益なものである
。However, according to the present invention, by supporting the fixed post through rollers, such stress is completely eliminated, so damage accidents caused by thermal expansion are suppressed, and the safety is high. This is very beneficial as it allows the use of posts with a smaller diameter than before.
なお本案ではコロを介在させたものについて説明したが
、これはコロに替えて他に車輪を使用するとか或いはス
ライド式にするなど変更することが可能である。Although this proposal has been described using rollers, it is possible to modify the structure by using other wheels instead of the rollers or using a sliding type.
