Abstract

本发明涉及一种用于玻璃板加热炉中电阻元件的支承架，该支承架具有基本上为连续延伸的，细长的支承表面，以便支承电阻元件。支承架零件用槽状铸件组成，彼此以铰接的方式固定。这种短支承架零件容易浇铸，并能组装成用于电阻元件之长而连续的支承架。上述支承架的热应力不会传给铰接点。一种长而连续的支承架结构就可相应地采用长而连续的电阻元件，因此能够迅速地更换电阻元件。

Description

本发明涉及一种用于玻璃板加热炉中电阻元件的支承架，该支承架具有基本上为连续、细长的支承表面，以便支承电阻元件。现有的电阻元件支承架是为某种预先确定了长度的电阻元件而制造的，加热炉沿纵向装有一排排分立的带支承架的电阻元件。只有等炉子冷却以后才能更换电阻，这就意味着停工时间长。所要求的分立的电阻元件也是很多的。
本发明之目的是提供一种新型的电阻元件支承架，以便克服上述缺点。
按照本发明，用一些铰接头将分立的支承架零件彼此固定，便可实现此目的。这种支承架零件最好是一些槽状铸件。
这种解决方法具有若干明显的优点：
可以浇铸成短的支承架零件，从而使浇铸工作较简便;
可以将这些短支承架零件组装成一些长的连续支承架;
在支承架内部可形成连续的管或槽，得以从管或槽的端部插入电阻元件;
更换电阻元件方便，不需等加热炉冷却;
分立的电阻元件的数量显著减少（例如，在热处理炉中所用之分立的电阻元件数仅为现用电阻元件数的1/3）。
下面参照附图来更详细地描述本发明的一个实施例，附图中：
图1为本发明的支承架零件的侧视图。
图2为上述零件的平面图。
图3为图1和图2中所示零件的横剖面。
图4为支承架零件之间连接部件的剖面图。
图5示出了通向炉壁，安装在支承架端部的支承架零件。
图6和图7分别为支承架尾端部件的侧视图和前视图。
图8为玻璃热处理炉端部截面的侧视图，在该炉中，本发明的电阻元件支承架用来支承安装在玻璃板支承辊上方的电阻元件。
图9为图8所示的热处理炉的端视图，该图更详细地表示出炉顶上按横向平行设置的支承架的安置情况。
支承电阻元件（图中未示出）的支承架包括一些分立的支承架零件1，这些零件内部构成槽状或管状空间2。每个支承架零件1的一端有一滑槽3同支承架零件另一端上的托架4相配合。滑槽3和托架4的重叠部分钻有跟销6相配的孔5。依次连接所需个数的支承架零件1，可得到长度合乎要求的支承架。
将这些支承架沿加热炉的横向并排地放置，使之基本上覆盖住炉子的全长（参见图8和9）。借助于固定在活节销6端部的轴承架7，使这些支承架得以安装在吊架上。轴承架7由铰接件8固定，铰接件8在炉子内部，对着穿过炉顶的吊杆9。这样，支承架可以自由地实现热膨胀运动，而不会在吊架引入端产生机械应力或引起热流失。
图5给出了用于支承架引入端以便有效地穿过炉子端壁的端部零件10为管状，并跟固定到加热炉端墙的连接法兰11相配合。此外，该零件10还跟具有孔5的插销套12相配合，而为下一个支承架零件1提供孔/活节销连接5、6。
支承架的尾部，也就是加热炉的相对端，通过孔/销铰接头14，5，6跟端板13相配合，端板13用作为插入支承架管状空间2的电阻元件（未画出）的终点挡板。借助于伸出部分15可 以防止端板13摆动，伸出部分15的上表面16靠在支承架1的底部表面上。
选择支承架零件的长度使之同铰接头和支承点之间的距离相匹配，该支承点处于上述支承架支承的电阻元件的陶瓷部件之间，这就能确保由热膨胀引起的变形不会明显地改变电阻丝和支承架之间的距离。因此本发明的铰接零件结构还有助于安全运行。
本发明不只限于上述实施例，在本工艺的技术领域内还可对其细节作种种修改，这些修改仍然包括在本发明的从属权利要求中。例如，可以采用任一已知的铰接方式或应用-已知的铰接头来设计出上述活接结合。在某些情况中，支承架零件的固定端最好做成彼此相同，而就其固定端而言，这就需要两种类型的支承架零件。
在所描述的例子中，本发明的支承架零件已用在沿着一加热炉纵向延伸的架空电阻上。此外，图8和图9还示出了加热炉的横向顶部和底部电阻1a以及纵向底部电阻1b。本发明的支承架零件则未曾在后一情况使用过。
