门型密封装置 35通过吊式安装机构 40吊装在环冷机台车 11的台车支撑 梁 37上， 使门型密封装置 35的重力作用在台车支撑梁 37上。 门型密封装置 35整体为环状回转体， 通过多个吊式安装机构 40分别吊装在各个台车支撑梁 37上。 台车支撑梁 37具有较强的支撑能力， 完全可以承受门型密封装置 35 的重量，避免因门型密封装置 35的重力和重力矩通过台车进风管 36作用在台 车内侧密封板 14上， 引起台车内侧密封板 14变形， 导致门型密封装置 35下 垂， 可保证环冷机 10正常工作。
一个环冷机台车 11的前置端 （相对于环冷机运行方向）通过铰接座（图 中未示出）与前置台车支撑梁 37的后置端相联接， 所述环冷机台车 11的后置 端与后一个台车支撑梁 37的前置端相抵接， 沿环冷机周向首尾相接， 组成环 冷机台车回转体 30的主要部分。每个台车支撑梁 37沿环冷机径向的两端分别 与内环梁 51 (相对于环冷机中心）和外环梁 52联接， 然后将周向相邻的内环 梁 51之间、相邻的外环梁 52之间各自分别联接， 形成一个多边形的环冷机台 车回转体 30。
环冷机台车回转体 30的内侧设置一定数量的水平的侧辊挡轮 53 , 侧辊挡 轮 53与台车支撑梁 37的内环梁 51的内侧 （相对于环冷机中心）联接， 侧辊 挡轮 53起着环冷机台车回转体 30的中心定位作用， 保证环冷机台车回转体 30沿轨道周向运行。 环冷机台车回转体 30的外侧水平设置一圓环形的驱动用 摩擦板 54, 驱动用摩擦板 54与台车支撑梁 37的外环梁 52的外侧联接。 环冷 机驱动装置（图中未示出）通过对驱动摩擦板 54施以水平切向力， 推动环冷 机台车回转体 30作圓周运动， 组成环冷机台车回转体 30的环冷机台车 11、 台车支撑梁 37同步作回转运动， 环冷机台车 11的内侧密封板 14带动台车进 风管 36同步作回转运动， 台车进风管 36和吊式安装机构 40同步带动门型密 封装置 35—起运转。
参见图 6,为本发明吊式安装机构 40第一实施例在图 4中的 A-A剖视图， 吊式安装机构 40上部为可调整吊式安装机构 40长度的螺栓结构 42, 螺栓结 构 42的螺栓套 421套在台车支撑梁 37的外围， 吊式安装机构 40的下部为吊 板 43 , 吊板 43为上宽下窄结构， 吊板 43下端设有销孔 44。 见图 4, 门型密 封装置 35的密封盖板 351的上端面设有两个孔板座 354。
安装时， 吊式安装机构 40的螺栓结构 42的螺栓套 421套在台车支撑梁 37的外围， 穿过台车支撑梁 37上的安装座， 并锁固。 使吊式安装机构 40联 接在台车支撑梁 37上； 使用销轴 45穿过吊板 43上的销孔 44和密封盖板 351 上端面的两个孔板座 354, 再旋转螺栓结构 42上的螺母， 调整吊式安装机构 40的长度， 吊起门型密封装置 35 , 将门型密封装置 35的重力作用到台车支撑 梁 37上，并将密封盖板 351上的各个与台车进风管 36联接的法兰面调节到同 一水平高度。
参见图 7,为本发明吊式安装机构 40第二实施例在图 4中的 A-A剖视图， 吊式安装机构 40上部为可调整吊式安装机构 40长度的螺栓结构 42, 下部为 吊板 43 , 吊板 43为上宽下窄结构， 吊板 43下端设有销孔 44。
安装时，吊式安装机构 40的螺栓结构 42穿过台车支撑梁 37上的安装座， 并锁固， 使吊式安装机构 40联接在台车支撑梁 37上； 使用销轴 45穿过吊板 43上的销孔 44和密封盖板 351上端面的两个孔板座 354, 再旋转螺栓结构 42 上的螺母， 调整吊式安装机构 40的长度， 吊起门型密封装置 35 , 将门型密封 装置 35的重力作用到台车支撑梁 37上，并将密封盖板 351上的各个与台车进 风管 36联接的法兰面调节到同一水平高度。 由于吊式安装机构 40的吊板 43下端的销孔 44与穿过孔板座 354的销轴 45沿轴向不固定， 可以相对滑移， 销轴 45的轴向与环冷机径向一致， 可以避 免由于环冷机台车回转体的圓度偏差与门型密封装置 35的圓度偏差所产生的 相互安装干涉； 避免环冷机台车在高温作用下的变形对门型密封装置 35产生 的挤压和拉扯。
环冷机 10运行一定时间后， 由于环冷机台车 11不停地运转， 环冷机台车 11 下方的车轮（图中未示出） 与支承轨（图中未示出）之间就会有磨损， 环 冷机 10运行时间越长， 磨损就约大， 使环冷机台车 11的车轮直径变小， 支承 轨的轨面下落， 这可导致环冷机台车 11车体下降 10 - 20毫米， 导致门型密封 装置 35同步下降， 严重时可能与环形液槽 34相接触， 影响环冷机 10正常运 行。 本发明可调整吊式安装机构 40的螺栓结构 42, 可适度缩短吊式安装机构 40的长度， 使门型密封装置 35适度上升， 避免因环冷机台车 11车体下降导 致门型密封装置 35与环形液槽 34相接触， 保证环冷机 10正常运行。
本发明吊式安装机构 40的吊板 43下端可设置为吊钩， 安装时，使用销轴 45穿过密封盖板 351上端面的两个孔板座 354, 再使用吊板 43下端的吊钩勾 住销轴 45 , 吊起门型密封装置 35。
一般情况下， 环冷机台车回转体存在不圓度， 环冷机台车 11在生产过程 中会有高温热变形， 这样， 门型密封装置 35就会受到挤压和拉扯， 就可能产 生形变， 影响环形风道 33的密封效果。 本发明密封盖板 351上端面的两个孔 板座 354的距离远大于吊板 43的厚度， 吊式安装机构 40的吊板 43可以沿销 轴 45作径向滑移， 可避免门型密封装置 35受到扭转和挤压，避免门型密封装 置与固定的环形液槽之间的干涉， 保证环形风道 33的密封效果和环冷机的工 作稳定性。
