Description

软管卷绕装置及其所应用的工程机械
本申请要求于 2008 年 5 月 14 日提交中国专利局、 申请号为 200810106538.5、 发明名称为"软管卷绕装置及其所应用的工程机械"的中 国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及一种软管卷绕装置， 特别涉及一种用于液压连续墙抓斗机 等工程机械的软管卷绕装置。 本发明还涉及一种应用上述软管卷绕装置的 工程机械。 背景技术
工程机械领域通常会应用软管卷绕装置， 特别是在液压动力执行机构 在工作过程中需要产生较大位移的设备（比如液压连续墙抓斗机） 中， 软 管卷绕装置得到了广泛的应用。
软管卷绕装置的基本作用是随着液压动力执行机构位移的变化而释放 或者收紧液压油软管， 从而持续地向液压动力执行机构提供液压动力， 并 且避免液压油软管出现缠绕等不利情况， 保证整个系统可靠地运行。
请参考图 1以及图 2 , 图 1为设有软管卷绕装置的工程机械的结构示 意图； 图 2为现有技术中一种典型软管卷绕装置的剖视示意图。 为了便于 观察软管卷绕装置的整体结构， 图 2中的软管卷盘 15以及马达减速机 16 用双点划线示意性地表示。
图 1中的工程机械具体为液压连续墙抓斗机 4, 其液压抓斗 3在工作 过程中需要在竖直方向上产生数十米的位移， 因此，液压油软管 17的长度 必须足够长、 软管卷绕装置 1的尺寸规格也必须足够大。
如图 2所示， 现有技术中一种典型的软管卷绕装置 1包括支座 11 , 支 座 11固定地设置于工程机械适当的位置。
支座 11具有中心腔体， 其中设置主轴管 12。 主轴管 12与支座 11之 间设置有轴承， 因此主轴管 12 可以在马达减速机 16 的带动下在支座 11 的支撑下转动。 支座 11与主轴管 12之间还应当设置高压油封 13 , 以避免 液压油泄露。
软管卷绕装置 1还包括外轴盘 14 , 外轴盘 14以常规的方式固定地套 装于主轴管 12的外侧， 且能够在主轴管 12的带动下与之同步转动。 外轴 盘 14的位置由主轴管 12支撑。
外轴盘 14可以同轴地固定连接软管卷盘 15 ,软管卷盘 15中可以盘绕 液压油软管 17。
马达减速机 16可以带动主轴管 12以适当的速度转动， 后者进而带动 外轴盘 14以及软管卷盘 15转动，这样盘绕于软管卷盘 15中的液压油软管 17即可以被释放或者被收紧， 从而可以稳定地为液压执行机构供油。
但是， 上述现有技术中的软管卷绕装置 1存在检修不方便的缺陷。 长期的磨损以及油压突然增大引起的高压冲击等意外情况都会导致支 座 11与主轴管 12之间的高压油封 13受损； 一旦受损， 必须及时更换高压 油封 13 , 以确保为液压执行机构提供压力符合要求的液压油。
更换高压油封 13需要将主轴管 12从支座 11中拆下；然而，如前所述， 软管卷盘 15通过外轴盘 14固定连接于主轴管 12的外侧，因此上述现有技 术的软管卷绕装置 1必须将软管卷盘 15、外轴盘 14与主轴管 12—同拆下。
如前所述， 很多工程机械在工作过程中， 其液压执行机构需要产生较 大的位移， 比如上述液压连续墙抓斗机 4, 其液压抓斗 3有时需要深入地 下五十多米； 因此， 很多工程机械都需要有较长的液压油软管 17 , 以及较 大较重的软管卷盘 15。 仍以上述液压连续墙抓斗机 4为例， 其所釆用的软 管卷盘 15的质量可达一吨左右。
由于软管卷盘 15的质量较重，往往需要动用起重设备以及较多的操作 人员才能顺利地更换高压油封 13 , 这显然费时费力、 将增加使用维护成本 并降低工程机械的工作效率， 而且有时作业现场难以满足起重设备的工作 要求， 高压油封 13的更换就更为困难。
当然， 发生其他故障时也可能需要将主轴管 12从支座 11中拆下， 此 时将存在相同的问题。
因此， 如何简单、 有效地完成对软管卷绕装置的维修操作， 进而降低 维护成本、 提供工程机械的工作效率， 是本领域技术人员目前需要解决的 技术问题。 发明内容
本发明的目的是提供一种软管卷绕装置，其维修操作较为简单、方便, 维护成本较低。 本发明的另一目的是提供一种应用上述软管卷绕装置的工 程机械。

本发明核心是提供一种软管卷绕装置， 其维修操作较为简单、 方便， 维护成本较低。 本发明的另一核心是提供一种应用上述软管卷绕装置的工 程机械。
为了使本技术领域的人员更好地理解本发明方案， 下面结合附图和实 施方式对本发明作进一步的详细说明。
请参考图 3 , 图 3为本发明所提供的软管卷绕装置一种具体实施方式 的剖视示意图。 为了便于观察软管卷绕装置的整体结构， 图 3中的软管卷 盘 25以及马达减速机 28用双点划线示意性地表示。
在一种具体实施方式中， 本发明所提供的软管卷绕装置 2包括固定连 接于工程机械上的支座 21。
支座 21具有内环壁 214, 内环壁 214之中具有中心腔体 211 , 中心腔 体 211中设置主轴管 22。 主轴管 22与内环壁 214之间可以设置若干轴承， 从而使主轴管 22可以由支座 21可旋转地支撑。 主轴管 22与内环壁 214 之间还设有高压油封 23 ,主轴管 22、支座 21以及高压油封 23因此可以形 成回转接头。
主轴管 22可以由内环壁 214支撑， 并可以在马达减速机 28的带动下 在支座 21的中心腔体 211中转动； 高压油封 23可以避免液压油的泄露。 支座 21进一步具有与内环壁 214大体同心的外环壁 212 , 外环壁 212 的内径应适当地大于内环壁 214的外径， 从而在外环壁 212与内环壁 214 之间形成环形腔体 213; 显然， 环形腔体 213的中心轴线应当与中心腔体 211 的中心轴线相重合。 外环壁 212可以通过螺栓或者其他常规的方式与 支座 21的主体部分固定连接。
请同时参考图 6和图 7 , 图 6为本发明所提供的外轴盘一种具体实施 方式的剖视示意图； 图 7为图 6所示外轴盘的侧视示意图。
软管卷绕装置 2进一步包括外轴盘 24。 外轴盘 24套装于主轴管 22的 外侧， 且与软管卷盘 25固定连接； 软管卷盘 25种缠绕有液压油软管 26。 外轴盘 24由支座 21可旋转地支撑。
具体地，外轴盘 24可以包括与支座 21的中心腔体 211同轴的轴套 241 , 轴套 241中具有内腔 243。轴套 241的内径可以略大于支座 21的内环壁 214 的外径， 且轴套 241的外径可以适当地小于外环壁 212的内径， 以便轴套 241可以设置于环形腔体 213之中， 且能够在轴套 241与内环壁 214或者 外环壁 212之间设置若干轴承。轴套 241的轴向长度应当大于环形腔体 213 的轴向长度， 以便轴套 241的末端位于环形腔体 213之外。
外轴盘 24还包括法兰盘 242 , 法兰盘 242固定连接于轴套 241伸出环 形腔体 213的端部外侧。可以通过常规的方式将法兰盘 242与软管卷盘 25 固定连接。
因此， 外轴盘 24可以通过其轴套 241可以可旋转地设置于支座 21的 环形腔体 213中，并可以通过其法兰盘 242与软管卷盘 25固定连接； 软管 卷盘 25以及液压油软管 26由此可以由支座 21可旋转地支撑。
为了使软管卷盘 25能够与主轴管 22同步转动，可以在外轴盘 24与主 轴管 22之间设置联轴器 27。
可以进一步将联轴器 27设为挠性联轴器，这样，可以补偿软管卷绕装 置 2由制造工艺精度、使用过程中的受力等因素所造成的微小的尺寸误差、 变形以及运动偏移， 从而消除上述制造精度、 变形对软管卷绕装置 2造成 的应力； 此外，将联轴器 27设为挠性联轴器还可以在一定程度上降低各部 件的加工精度要求， 方便了加工操作、 降低了制造成本。
联轴器 27中最好还具有弹性元件， 这样， 联轴器 27不但可以能够补 偿位移， 还可以起到减震的作用。
具体地， 如图 3所示， 联轴器 27可以包括外轴套 271、 弹性柱销 272 以及内轴套 273。
外轴套 271与外轴盘 24可拆卸地固定连接，例如， 两者可以通过螺栓 连接；恰当地选择外轴套 271的外径，可以将其插装入轴套 241的内腔 243 中。
内轴套 273与外轴套 271同心设置，且内轴套 273与主轴管 22可以通 过平键 29连接， 以传递扭矩。
内轴套 273与外轴套 271相对的表面之间具有柱销孔， 所述柱销孔之 中设置弹性柱销 272。 所述柱销孔与弹性柱销 272之间应当具有适当的间 隙。 弹性柱销 272用来传递扭矩， 并对主轴管 22与软管卷盘 24的微小相 对偏移进行一定的补偿， 同时起到减振作用。
当主轴管 22在马达减速机 28的带动下转动时，可以通过平键 29带动 内轴套 273 , 内轴套 273通过弹性柱销 272带动外轴套 271 ; 由于外轴套 271与外轴盘 24固定连接， 因此， 外轴盘 24将随着主轴管 22同步转动， 与外轴盘 24固定连接的软管卷盘 25也将随着主轴管 22同步转动。
当然， 联轴器 27也可以釆用其他的具体形式， 在此不再赘述。
拧开联轴器 27的外轴套 271与外轴盘 24之间的联接螺栓， 就可拆除 外轴套 271 ,并移除弹性柱销 272。软管卷盘 25与主轴管 22的联接因此断 开。 由于软管卷盘 25通过外轴盘 24独立地支承在支座 21上， 主轴管 22 因此可被单独拆下， 以进行更换高压油封 23等维修操作。
本发明所提供的软管卷绕装置 2的外轴盘 24以及主轴管 22均相互独 立地由支座 21可旋转地支撑， 外轴盘 24以及主轴管 22通过联轴器 27连 接， 以便传递扭矩。 当软管卷绕装置 2发生高压油封受损以及其他故障时， 可以仅将主轴管 22拆下，而不必同时拆卸外轴盘 24以及与外轴盘 24固定 连接的软管卷盘 25。
相对于重量可达一吨的软管卷盘 25 , 主轴管 22通常仅重十几公斤， 因此， 本发明所提供的软管卷绕装置 2在维修操作时不需要起重设备， 一 个操作人员即可顺利完成。 本发明所提供的软管卷绕装置 2可以显著地减 小维修操作的工作量， 省时省力、 降低维护成本， 并显著提高工程机械的 工作效率。
请参考图 8 , 图 8为本发明所提供的外轴盘另一种具体实施方式的剖 视示意图。
在另一种具体实施方式中， 本发明所提供的外轴盘 24包括与支座 21 的中心腔体 211同轴的轴套 241 ,轴套 241中具有内腔 243。轴套 241的内 径可以略大于支座 21的内环壁 214的外径，且轴套 241的外径可以适当地 小于外环壁 212的内径， 以便轴套 241可以设置于环形腔体 213之中， 且 能够在轴套 241与内环壁 214或者外环壁 212之间设置轴承。 轴套 241的 轴向长度应当大于环形腔体 213的轴向长度， 以便轴套 241的末端位于环 形腔体 213之外。
外轴盘 24还包括法兰盘 242 ,法兰盘 242可拆装地固定连接于轴套 241 伸出环形腔体 213的端部外侧；比如可以通过螺栓将轴套 241与法兰盘 242 固定连接， 拆下螺栓即可将两者分离。 这进一步方便了维修操作。
本发明所提供的工程机械包括上述软管卷绕装置 2 , 其他结构不再赘 述。 所述工程机械具体可以是液压连续墙抓斗机。
以上对本发明所提供的软管卷绕装置及其所应用的工程机械进行了详 以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。 应当指 出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下， 还可以对本发明进行若干改进和修饰， 这些改进和修饰也落入本发明权利 要求的保护范围内。
