Description

[根据细则26改正27.12.2017]　一种绝缘复合式接触网支持装置 技术领域
本发明属于电气化轨道交通技术领域，涉及沿轨道交通线路上空架设的向电力机车供电的输电线路即接触网，尤其涉及接触网的绝缘悬挂装置。
背景技术
接触网是沿电气化铁路架设的，专门用于向电力机车或动车组提供电能的电能传输结构，主要由接触悬挂、定位与支持装置、支柱与基础构成，在电气化铁路上运行的电力机车或动车组靠安装在其车顶的受电弓与接触悬挂滑动接触，从而完成电能从电力系统向机车的传输，进而驱动列车前进。
其中，定位与支持装置是用来确定接触悬挂整体空间位置的关键部件，现有定位与支持装置包括平腕臂及及与其相连的绝缘子、斜腕臂及与其相连的绝缘子、斜腕臂支撑、定位管、定位管支撑或拉线、定位支座、定位器等构成，其中各零件之间的连接靠各类连接件相连，包括套管双耳、套管单耳、螺纹套管等，并通过若干螺栓螺母加以紧固。
现有定位与支持装置主要存在以下缺点：
1、由零部件失效导致的接触网故障风险高。接触网在电气化铁路中无备用，支持与定位装置相对接触网也无备用，任何一个零部件的失效均可能引发接触网结构改变、功能失效，即接触网故障，一旦接触网故障，以电能为唯一动力来源的列车或动车组将停运，会导致经济损失和恶劣社会影响。
2、绝缘子易闪络且安装维护成本高。现有定位与支持装置包含两套绝缘子，材料一般为陶瓷，重量大，施工过程费事费力。另外，在重污染地区绝缘子易出现污染物附着，并导致绝缘强度下降，实际运营维护中一般靠人力擦拭，费事费力、维护效率低下。
3、安装工艺复杂。现有定位于支持装置的安装步骤中的重要一步是腕臂预配，即在车间里集中定制全线每一套接触网支持与定位装置，然后才运送至现场安装，工序繁多。
4、常出现因鸟类筑巢而引发短路事故。在现有技术情况下，当鸟类在绝缘子上筑巢时，容易短接绝缘子两侧，使高压侧与接地侧短路，进而引发线路跳闸。
发明内容
本发明的目的在于改进现有技术的不足，提供一种新型绝缘复合材料接触网支持装置，减少支撑装置的零部件，从而降低了故障风险，安装简便，且无需置入绝缘子。
为达到上述目的，本发明采用的技术方案是：
一种绝缘复合式接触网支持装置，包括平腕臂、斜腕臂、斜腕臂支撑杆、定位管、对定 位管进行支撑的硬支撑杆和连接管，所述平腕臂、斜腕臂、斜腕臂支撑杆、定位管、硬支撑杆和连接管由绝缘材料一体压制成整体结构；；
所述平腕臂的后端与斜腕臂的后端连接形成V型结构，所述平腕臂的前端与斜腕臂支撑杆的前端连接；所述斜腕臂支撑杆的后端与斜腕臂连接，在斜腕臂支撑杆与斜腕臂的连接点处还连接所述硬支撑杆的前端，由斜腕臂、斜腕臂支撑杆和硬支撑杆形成X型结构；
所述硬支撑杆的后端与定位管的前端连接，所述连接管的两端分别连接至所述定位管的后端和平腕臂的后端，所述定位管与平腕臂相平行；
在所述平腕臂与斜腕臂支撑杆的连接处设置有用于固定支柱的固定件Ⅰ，在斜腕臂的前端设置有用于固定支柱的固定件Ⅱ，所述平腕臂与斜腕臂的连接处设置有用于固定承力索的支座固定件Ⅰ，所述定位管上设置有用于固定定位器的支座固定件Ⅱ。
进一步的是，绝缘复合式接触网支持装置支撑接触悬挂安装在直线、曲线内或者曲线外的电气化铁路轨道上方，并包括接触网正定位或者反定位的布置和安装，以及弹性吊索的安装；因为曲线内、直线或者曲线外的正定位和反定位囊括了绝大多数接触悬挂布置条件；本装置用更少的接触网支持装置型号满足接触悬挂各种空间位置布置的要求。
进一步的是，定位器支座安装在支座固定件Ⅱ上，且所述定位器支座采用正定位或反定位安装；定位器支座安装点在接触线正上方的形式且采用连续大小规格，使承力索与接触线空间的安装位置调整范围能完全覆盖原有调整范围。
正定位或者反定位安装是接触网的固有要求接触网一般每50m一处支持装置，一般是相邻两个支持装置一个正定位一个反定位，从而实现接触线“之”字型布置。
进一步的是，在所述支座固定件Ⅰ上设置有承力索滑轨，在所述承力索滑轨上设置有承力索的定位装置；实现承力索支座安装的局部调整。
进一步的是，在所述支座固定件Ⅱ上设置有滑轨，在所述滑轨上设置有定位器的定位装置；实现定位器支座安装的局部调整。
进一步的是，所述绝缘材料为环氧树脂或聚苯硫醚树脂与玻璃纤维复合材料，实现支撑装置的绝缘效果；采用这种复合材料的原因是其强度高、耐腐蚀、绝缘性好、成本较低。
进一步的是，在所述绝缘材料外表面附着聚酰亚胺涂层，用于防止紫外线对内部非金属材料的破坏。
聚酰亚胺涂层可以阻挡紫外线，防止紫外线对环氧树脂与玻璃纤维复合材料的破坏；聚酰亚胺涂层有很好的憎水性，很难在其表面形成水膜而导致绝缘强度下降；聚酰亚胺涂层不易附着空气污染物，在雾霾较严重的地区也不易发生因污染物附着而导致的闪络现象。
为了满足接触网支持装置的绝缘要求，并且不使用绝缘子，接触网支持装置应采用绝缘材料，为了满足接触网支持装置对于接触悬挂的支持与定位要求，需要接触网支持装置具有足够的机械载荷承载能力，经过比选，树脂基绝缘复合材料最为合适，树脂基绝缘复合材料中，环氧树脂与玻璃纤维复合材料具有成本低的优势，聚苯硫醚树脂与玻璃纤维复合材料具有在紫外线照射条件下抗老化能力强的优势，两种方案均可以用于制造接触网支持装置。
进一步的是，所述平腕臂、斜腕臂、斜腕臂支撑杆、定位管、硬支撑杆和连接管均为空心管、实心棒或有填充材料的空心管，平腕臂、斜腕臂、斜腕臂支撑杆、定位管、硬支撑杆和连接管的连接处均为一体式结构。
采用本技术方案的有益效果：
1、大量减少零部件；该新型绝缘复合材料接触网支持装置采用整体成型工艺，在一套接触网支持与定位装置中作为单个零件使用，省去了中间多个连接件及其配套紧固件。
2、绝缘可靠性高；由于该新型绝缘复合材料接触网支持装置采用绝缘复合材料，且两端金属部件连接的中间爬距满足绝缘要求，故新的结构取消了传统的瓷绝缘子，大幅提升了安装和后期维护效率，降低了维护成本。
3、安装工艺简单；该新型绝缘复合材料接触网支持装置整体成型，成品的规格统一，不存在逐套定制的现场预配工序，安装简单，大量节省安装施工时间和人力成本。
4、有效降低鸟类筑巢引发短路事故风险；该新型绝缘复合材料接触网支持装置高压侧与接地侧空间距离远大于现有技术的相应距离，鸟类即使在接触网支持装置上筑巢，也很难搭接高压侧与接地侧，即有效降低因鸟类筑巢引发短路跳闸事故风险。

作为上述实施方案的优化方案，在所述支座固定件Ⅰ9上设置有承力索滑轨，在所述承力索滑轨上设置有承力索的定位装置，通过滑动支座固定件Ⅰ9调节本装置在承力索上的位置，并通过承力索定位装置固定；在所述支座固定件Ⅱ10上设置有滑轨，在所述滑轨上设置有定位器的定位装置，通过滑动支座固定件Ⅱ10调节本装置在定位器上的位置，并通过定位器定位装置固定。
上述的固定件Ⅰ7、固定件Ⅱ8、支座固定件Ⅰ9和支座固定件Ⅱ10，均可采用本领域中用于固定的各种常规结构的固定件，例如螺丝或卡扣等。
一种绝缘复合式接触网支持装置，该装置主要由绝缘复合材料材料制成，仅在该装置与外部零部件的接口部位有局部的金属构件。
所述该装置与外部零部件的接口部位包括：平腕臂1根部、斜腕臂2根部、支座固定件Ⅰ9和支座固定件Ⅱ10。
本发明提供的绝缘复合材料接触网支持装置的功能替换了现有装置中平腕臂、与平腕臂相连的绝缘子、斜腕臂、与斜腕臂相连的绝缘子、平腕臂与斜腕臂间的连接件、斜腕臂支撑、斜腕臂支撑与平腕臂间的连接件、斜腕臂支撑与斜腕臂间的连接件、定位管、定位管硬支撑或连接管、定位管与斜腕臂间的连接件所组成的部件的整体功能。
所述绝缘材料为环氧树脂或聚苯硫醚树脂与玻璃纤维复合材料，实现支撑装置的绝缘效果；采用这种复合材料的原因是其强度高、耐腐蚀、绝缘性好、成本较低。
在所述绝缘材料外表面附着聚酰亚胺涂层，用于防止紫外线对内部非金属材料的破坏以及增加环境污染下的绝缘强度。
本发明提供的绝缘复合材料接触网支持装置为一个经过固化的零件，其内部不可拆分，不可调整，而考虑到工程中接触网承力索和接触线架设于支持装置上的位置是变化的，且需要调整，所以本发明在承力索支座安装位置附近预留了可调范围，在定位器支座11位置也预留了可调范围。
所述平腕臂1、斜腕臂2、斜腕臂支撑杆3、定位管4、硬支撑杆5和连接管6均为空心管、实心棒或有填充材料的空心管，平腕臂1、斜腕臂2、斜腕臂支撑杆3、定位管4、硬支撑杆5和连接管6的连接处均为一体式结构。
为解决固化结构情况下接触悬挂可调范围有限的问题，本发明通过设计多种尺寸的绝缘复合材料接触网支持装置来实现，通过不同规格绝缘复合材料接触网支持装置的可调范围衔接，确保接触悬挂可调节范围与当前技术下接触悬挂可调节范围一致。
为在有限的活动范围内满足曲线内、直线和曲线外的接触线安装要求，且能同时满足正定位和反定位的定位器支座11固定位置，本发明提出一种新的定位器支座11形式，即正定位和反定位的定位器支座11固定位置位于接触线正上方。
本发明提供的一种绝缘复合式接触网支持装置，固定件Ⅰ7、固定件Ⅱ8分别通过旋转双耳与支柱相连，承力索支座固定于支座固定件Ⅰ9上，且可以在靠近支柱或远离支柱方向调整安装位置，定位器支座11固定于支座固定件Ⅱ10上，且可以在靠近支柱或远离支柱方向调整安装位置。
上述实施例是本发明方案的基本结构，在实施例一的基础上，本发明还可以有如下拓展结构：
在本实施例二中，如图4所示，提出另一种结构的绝缘复合式接触网支持装置，在实施例一的基础上，所述定位管4和硬支撑杆5在同一水平线上。
在本实施例三中，如图5所示，提出另一种结构的绝缘复合式接触网支持装置，在实施例一的基础上，所述连接管6采用多边形结构。
在本实施例四中，如图6所示，提出另一种结构的绝缘复合式接触网支持装置，在实施例一的基础上，所述定位管4和连接管6构成矩形结构。
在本实施例五中，如图7所示，提出另一种结构的绝缘复合式接触网支持装置，在实施例一的基础上，所述定位管4和连接管6构成矩形结构且在矩形结构对角线上设置有连接杆。
在本实施例六中，如图8所示，提出另一种结构的绝缘复合式接触网支持装置，在实施例一的基础上，所述定位管4和连接管6构成矩形结构且在矩形结构对角线上设置有连接杆，且在固定件Ⅰ7和固定件Ⅱ8件设置有固定杆12。
在本实施例七中，如图9所示，提出另一种结构的绝缘复合式接触网支持装置，在实施例一的基础上，所述连接管6采用倾斜直线型结构。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
