Description
一种型材专用移动式龙门起重机
技术领域
[0001]本实用新型涉及起重机技术领域，特别是涉及一种型材吊运用的龙门式起重机。
背景技术
[0002]铝型材在原料氧化处理前和处理完成后、水泥电杆在成型干燥后、塑料水管等型 材的转运，都需要通过起重机进行吊运，但是现有的通用桥式起重机采用钢丝绳连接吊钩 吊运重物，运行平稳性差，检修、更换配件也非常不便;且同步作业和精确定位的精度也差； 型材在吊运时容易摆动，安全性、稳定性都很差。因此，有必要对现有的通用桥式起重机进 行改进和优化。 实用新型内容
[0003]为解决现有技术的不足，本实用新型提供一种稳定性高、安全性好的型材专用的 移动式龙门起重机。
[0004]本实用新型解决其技术问题所采用的技术方案是：
[0005] —种型材专用移动式龙门起重机，包括两个由大车运行机构驱动分别在型材氧化 池或存放处两侧水平移动的下横梁，下横梁上设有支承柱，两支承柱顶端连接有主梁，主梁 两端上部设有提升机构，所述主梁采用箱形实腹梁结构，其两端下侧设有垂直臂，两垂直臂 上固定有相对的槽形起升架，槽形起升架内设置有由提升机构链轮链条式驱动上下滑行的 滑动小车，滑动小车上装有固定吊钩或吊钩开合机构;提升机构包括由起重机专用的YZ绕 线式电动机驱动的起升减速机，起升减速机输出端通过链轮联轴器连接有提升链轮，提升 链轮与滑动小车之间通过链条连接，两提升机构同步同速运行;两垂直臂上均装有配重块， 其中一垂直臂上还装有驾驶室。
[0006] 进一步，每一所述槽形起升架上设有滑槽，滑动小车可上下移动的装在滑槽内，YZ 绕线式电动机连接有变频器。
[0007] 进一步，所述提升链轮的传动轴端部连接有提升制动轮，提升制动轮外装有YWZ型 液压推杆常闭式的提升制动器。
[0008] 进一步，所述大车运行机构包括立式驱动装置和与之相连的车轮，立式驱动装置 采用锥形制动电动机，并连接有变频器。
[0009] 进一步，所述车轮采用有轨钢轮或橡胶轮。
[0010] 进一步，所述下横梁采用钢板压延成U型槽状，其槽口采用钢板封闭，焊接成箱型 结构。
[0011] 进一步，每一所述支承柱包括两根相向倾斜固定在下横梁上的支腿，主梁的两端 两侧分别通过高强螺栓固定在支腿顶端。
[0012] 进一步，所述主梁两端上侧固定有驱动架，提升机构安装在驱动架上，驱动架通过 螺栓安装或焊接在主梁两端上侧。
[0013] 本实用新型的有益效果是:通过采用链轮联轴器连接起升减速机和提升链轮，连 接性能好，运行更加平稳，检修、更换也更加方便;两提升机构同步同速运行所提供的集中 驱动可实现高精度的同步作业和精确定位;通过吊钩开合机构控制挂钩自动勾住承载型材 的特制排架两端吊钩位，或通过固定吊钩勾住排架两端吊钩位，并在链轮链条式的提升机 构驱动下，于槽形起升架上平稳的上下运行，可有效的克服钢丝绳吊钩吊运型材时摆动大、 安全性差的问题，且在配重块的平衡下，整机运行时稳定性更强。
附图说明
[0014] 下面结合附图和实施例对本实用新型做进一步说明。
[0015] 图1是本实用新型的结构示意图；
[0016] 图2是图1的侧视结构示意图；
[0017]图3是图2中A部分的放大图；
[0018]图4是本实用新型中支腿的结构示意图。
具体实施方式
[0019] 参照图1至图4, 一种型材专用移动式龙门起重机，包括两个由大车运行机构驱动 分别在型材氧化池或存放处两侧水平移动的下横梁1，下横梁1上设有支承柱2,两支承柱2 顶端连接有主梁3，主梁3上部两端设有提升机构4，所述主梁3采用箱形实腹梁结构，其两端 下侧设有垂直臂5,两垂直臂5上固定有相对的槽形起升架6,槽形起升架6内设置有由提升 机构4链轮链条式驱动上下滑行的滑动小车，滑动小车上装有固定吊钩或吊钩开合机构7， 两侧的固定吊钩或两侧的吊钩开合机构7的挂钩8相向设置;提升机构4包括由起重机专用 的YZ绕线式电动机驱动的起升减速机9,起升减速机9输出端通过链轮联轴器10连接有提升 链轮11，提升链轮11与滑动小车之间通过链条连接，两提升机构4同步同速运行;垂直臂5上 还装有配重块12,一垂直臂5上装有驾驶室13。通过采用链轮联轴器10连接起升减速机和提 升链轮，连接性能好，运行更加平稳，检修、更换也更加方便;两提升机构4同步同速运行所 提供的集中驱动可实现高精度的同步作业和精确定位;通过吊钩开合机构7控制挂钩8自动 勾住用于承载氧化铝型材、塑料水管、水泥电杆或其他型材的特制排架两端吊钩位，或通过 固定吊钩勾住排架两端吊钩位，并在链轮链条式的提升机构驱动下，于槽形起升架6上平稳 的上下运行，可有效的克服钢丝绳吊钩吊运型材时摆动大、安全性差的问题，且在配重块12 的平衡下，稳定性更强。而通过驾驶室13操作，位置较地面高，视野更清晰，看得更清楚，操 作更加精准，从而提高了工作效率，同时也可提高吊运作业的安全性。
[0020] 作为上述技术方案的进一步改进，每一所述槽形起升架6上设有滑槽，滑动小车可 上下移动的装在滑槽内，每一滑动小车上均装有固定吊钩或吊钩开合机构7,提升链轮11通 过链条连接滑动小车，并通过YZ绕线式电动机驱动起升减速机9带动滑动小车在滑槽内上 下移动，YZ绕线式电动机连接有变频器。通过两边的提升链轮11同步提升两端的固定吊钩 或吊钩开合机构，固定吊钩或吊钩开合机构上的挂钩勾住装有氧化铝型材、塑料水管、水泥 电杆或其他型材的特制排架两端，从而达到提升和移动氧化铝型材、塑料水管、水泥电杆或 其他型材的要求，且提升速度可通过变频器进行调整，适应性强。
[0021] 作为上述技术方案的进一步改进，所述提升链轮11的传动轴端部连接有提升制动 轮，提升制动轮外装有YWZ型液压推杆常闭式的提升制动器14。通过YWZ型液压推杆常闭式 的提升制动器14可快速制动，精准刹车，快速、准确的将氧化铝型材、塑枓水官、水泥电种现 其他型材提升、下放至指定高度，提高了工作效率。 _
[0022]作为上述技术方案的进一步改进，所述大车运行机构包括立式驱动装置15和与之 相连的车轮16,立式驱动装置15采用锥形制动电动机，并连接有变频器。通过锥形制动电动 机制动，制动快速，车轮直接与立式驱动装置相连，从而保证了定位的准确性，可准确的运 行至指定位置，且运行速度可通过变频器进行调整，适应性强。
[0023]作为上述技术方案的进一步改进，所述车轮16采用有轨钢轮或橡胶轮，采用有轨 钢轮可使整个机器在轨道上前、后运行，较为平稳，但噪声稍大;而采用橡胶轮，则可在任何 平整的路面运行，不需要铺设路轨，大车运行场地灵活机动，可节省基础建设的投入成本。 [W)24]作为上述技术方案的进一步改进，所述下横梁1采用钢板压延成U型槽状，其槽口 采用钢板封闭，焊接成箱型结构。箱型结构强度高，能够满足下横梁1的承载要求，又可以节 省大量的材料，从而降低制造成本。
[0025]作为上述技术方案的进一步改进，每一所述支承柱2包括两根相向倾斜固定在下 横梁1上的支腿I7,主梁3的两端两侧分别通过高强螺栓固定在支腿17顶端。由于三角形的 稳定性高，两相向倾斜的支腿17可承受很高的压力，不仅节省了材料，也使得整体结构更加 稳定，不容易倾倒。
[00^6]作为上述技术方案的进一步改进，所述主梁3两端上侧固定有驱动架18,驱动架18 的尚度方式米用通过螺栓安装固定或采用焊接的方式固定，提升机构4安装在驱动架18上， 使得检修工作更加方便。
[0027]以上所述，只是本实用新型的较佳实施方式，但本实用新型并不限于上述实施例， 只要其以任何相同或相似手段达到本实用新型的技术效果，都应包含在本实用新型的保护 范围之内。
