Description

一种壁行式起重机结构
技术领域
本发明涉及一种壁行式起重机，特别适用于借助车间立柱焊接使用。
背景技术
目前，市场上存在的壁行式起重机，以国家专利局授权的专利号2011203523898和2011800564738为例，其特点是由两个水平端和一个垂直端梁组成，需要在车间立柱上焊接两只牛腿，两个行车梁分别与两只牛腿固定，需铺设三根道轨，以上结构和制作使得壁行式起重机显得复杂和笨重，尤其是在车间的立柱上要焊接两只牛腿，车间的制作成本相应增加，更为重要的是，如果电动葫芦突然卸载或钢丝绳突然断裂时，悬臂梁会受到很大向上的弹力，这时下边的垂直端梁和水平端梁受到冲击后就会立即脱槽，使起重机掉落下来，后果不堪设想。
发明内容
本发明的任务是提出一种在工作时起重机脱轨后不会掉落，结构紧凑，成本低的一种壁行式起重机。
本发明的任务是这样完成的，它包括车间立柱上焊接的牛腿，其特征在于：起重机的上承重梁位于牛腿的上侧安装，牛腿的上面铺设有上轨道，上端梁的两端各安装有大车运行机构，大车运行机构上设置有上水平轮组并通过螺栓固定，所述上水平轮组沿着上轨道运行，上支撑用螺栓固定在上端梁上，所述上支撑和下支撑之间用调节法兰连接，下支撑的上部与上支撑连接，下部的上侧通过螺栓与下端梁连接，下支撑的中部安装有下水平轮组，所述下水平轮组上的车轮与下端梁上铺设的下道轨呈立面接触，所述下水平轮组型状为7字其端部用螺栓固定在下支撑上，下端梁的侧面安装两个安全反钩。调节法兰的作用是调节上端梁和下端梁车轮踏面的距离，所述下支撑形状呈J型。
本发明具有以下效果：本技术方案结构紧凑、节约材料、方便运输，特别是在起重机在工作时如出现脱轨时，由安全反钩保护不会掉落，安全有保障，并且杜绝事故的发生。
附图说明
图1是本发明的主视图；图2是图1的右视图；图3是端梁的结构示意图；图4是上支撑结构示意图；图5是下支撑结构示意图；图6是上水平轮结构示意图；图7是图6的侧视图；图8是下水平轮结构示意图；图9是图7的侧视图。
图面说明：1、车间立柱，2、牛腿，3、上水平轮，4、上端梁，5、上道轨，6、大车运行机构，7、上支撑，8、调节法兰，9、下支撑，10、悬臂梁，11、电动葫芦，12、下水平轮组，13、下轨道，14、下端梁，15、安全反钩。
具体实施方式
结合以上附图详细描述实施例，如图1和图2所示，牛腿2的一端焊接在车间的立柱1上，起重机的上承重梁位于牛腿的上侧安装，牛腿的上面铺设有上轨道5，上端梁4的两端各安装有大车运行机构6，大车运行机构上设置有上水平轮组3并通过螺栓固定（如图6所示），所述上水平轮组3沿着上轨道运行，上支撑7用螺栓固定在上端梁上（如图4所示），所述上支撑和下支撑9之间用调节法兰8连接，调节法兰的作用是调节上端梁和下端梁车轮踏面的距离，使上下端梁的车轮都有效接触到道轨，所述下支撑形状呈J型，下支撑的上部与上支撑连接，下部的上侧通过螺栓与下端梁14连接，并且安装有调节法兰便于调整下端梁14的高度，下支撑的中部安装有下水平轮组12，所述下水平轮组上的车轮与下端梁上铺设的下轨道13呈立面接触，所述下水平轮组型状为7字，型其端部用螺栓固定在下支撑上（如图8和图9所示）。
所述下端梁14的侧面安装两个安全反钩15，如图1和图2所示，其目的是图果悬臂梁10受到向上的张力，安全反钩会挂在下行端梁上，防止起重机脱轨。
为方便运输，该起重机上的悬臂梁和下支撑也用法兰螺栓连接，到安装现场再组装。为了节约原材料，将悬臂梁现有的形状箱型改为截面梁，与法兰处连接时截面积大，端部梁截面小，这样的设计是因为悬臂梁的最大弯矩位于梁的根部，符合力学特性，电动葫芦11挂在悬臂梁的下方，可左右无障碍自动运动。壁行式起重机按照上述所描述的各部件之间组装好后，上端梁在上轨道的上方，下端梁位于下道轨的下方，由于悬臂梁和电动葫芦的自重及吊重，会使上端梁受到一个向右的分力，下端梁受到一个向左的分力，这时上水平轮组就会碰到上轨道的侧面，防止上端梁向右运行而脱轨，同时下端梁也会受到一个向左的分力，这时下支撑上的水平轮组也会碰到下行车梁的立板，下端梁的车轮也会碰到下轨道，防止下端梁向左运动。为了增加车轮的踏面宽度和活动范围，该起重机的上端梁和下端梁的车轮均为无缘轮。这样，起重机的上端梁和下端梁就不会左右运动，起重机的悬臂就固定了。起重机运行机构安装在上端梁上，来带动起重机只能沿着行车梁的方向运动。当出现电动葫芦突然卸载或钢丝绳突然断裂时，悬臂梁受到向上的弹性力，这时上水平轮组的右侧水平车轮会碰到上轨道的右侧，下边安全反钩的右侧面会碰到下行车梁的下盖板处，同时下端梁的车轮也会阻止起重机向上跳动，这样就阻止了起重机脱轨，防止安全事故的发生。
