Description

一种用于转辙机的锁闭机构
本申请要求在2019年1月3日提交中国专利局、申请号为201910005651.2的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本发明属于轨道交通技术领域，具体涉及一种用于转辙机的锁闭机构。
背景技术
转辙机是一种重要的铁路道岔转换设备，其作用为转换和锁闭道岔，改变道岔开通方向，并对道岔的位置进行监督检查。转辙机是保障铁路行车安全，提高运输效率的重要保证。
锁闭机构是转辙机内的关键部件，转辙机通过锁闭机构实现对道岔的锁定，对比文件CN104494647A描述了国内常用的转辙机锁闭机构，其动作杆上通过销轴安装有两个锁块，该锁闭方式，锁块围绕销轴旋转，转辙机在转换道岔过程中锁闭铁、动作杆及锁块之间的受力不断发生变化，受力不均衡，转辙机在锁闭过程中会产生逐渐增大的锁闭增力，转辙机转换和锁闭过程中受力状态不好，影响转辙机转换平稳性，尤其是在转辙机动作杆受到外部冲击时，会影响转辙机对道岔的锁闭。
发明内容
为提升转辙机用锁闭机构的稳定性及可靠性，本发明提供一种用于转辙机的锁闭机构，所述锁闭机构包括锁闭铁、动作杆、动作块、锁块组、油缸组成、阻尼机构和壳体；所述锁闭铁的一侧设置有形状相同的第一凹槽和第二凹槽；所述锁块组包括第一锁块和第二锁块，所述动作块上设置有两个滑槽，所述的第一锁块和第二锁块分别安装在两个所述滑槽内，所述的动作杆与动作块固定连接；所述锁闭铁的一侧和所述动作块的一侧滑动贴合，所述动作块的另一侧和所述油缸组成的外缸套的一端滑动贴合，所述外缸套的一端对称中心设置有斜面突起结构；所述阻尼机构设置在所述锁闭铁和所述外缸套之间。
进一步地，所述第一锁块和第二锁块的结构大小相同且均为菱形结构。
进一步地，所述的油缸组成还包括活塞杆、油缸缸体，所述活塞杆固定在 所述壳体内，所述外缸套套接在所述油缸缸体上。
进一步地，所述阻尼机构包括摩擦块、弹簧和芯轴，所述弹簧的一端和所述芯轴的一端均与所述锁闭铁的一侧固定连接，所述弹簧的另一端和所述摩擦块的一端固定连接，所述摩擦块的另一端和所述外缸套的一端贴合，所述芯轴套接在所述弹簧内。
进一步地，所述锁闭铁固定安装在所述壳体内；所述外缸套和动作杆分别与所述壳体滑动连接，所述动作杆的两端与道岔连接。
本发明的技术效果和优点：
1、本发明通过锁闭铁、锁块、动作杆、动作块以及外缸套共同作用，实现了转辙机的锁闭功能，使得道岔完成转换后，锁闭机构能够提供可靠稳定的锁闭支撑力，将道岔锁定在终端位置，提高了转辙机的安全稳定性；
2、本发明在转辙机转换过程中，锁闭铁、动作杆、外缸套及锁块之间的力保持恒定，各部件受力状态好，运行平稳；
3、本发明的两个锁块与动作杆不是通过销轴连接，锁块在锁闭过程中，锁闭增力很小，且锁闭增力保持恒定，锁闭更可靠；
4、本发明的两个锁块结构简单，体积小，便于拆装维护。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所指出的结构来实现和获得。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作以简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例的锁闭机构左侧终端位置锁闭图；
图2为本发明实施例的锁闭机构中间转换位置图；
图3为本发明实施例的锁闭机构右侧终端位置锁闭图；
图4为本发明实施例的阻尼机构结构示意图。
图中：1锁闭铁、1-1第一凹槽、1-2第二凹槽、2动作杆、3动作块、4-1第一锁块、4-2第二锁块、5-1外缸套、6-1摩擦块、6-2弹簧、6-3芯轴。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地说明，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
此处以液压转辙机为例进行示例说明，但是本发明所述的锁闭机构还适用于其它转辙机。
本发明具体的工作原理为：油缸组成的活塞杆固定在壳体内，油缸缸体带动外缸套5-1动作，外缸套5-1推动锁块组动作；进一步的，带动动作杆2及动作块3移动，动作杆2与道岔连接，从而带动道岔运动；进一步的，在一侧终端位置时，外缸套5-1、锁闭铁1和锁块组共同作用完成转辙机的锁闭功能，实现对道岔的转换及锁闭。
图1、图2及图3分别为本发明锁闭机构左侧终端位置锁闭图、中间转换位置图及右侧终端位置锁闭图，即转辙机的主锁闭机构的动作示意图。示例性的，以锁闭铁1左侧终端锁闭位开始，油缸组成的外缸套5-1向右移动，外缸套5-1上的斜面突起结构的右侧斜面与第二锁块4-2的斜面接触，外缸套5-1继续向右移动，推动第二锁块4-2并带动动作块3一起动作，动作块3与动作杆2连接并同步运动，此时第一锁块4-1从锁闭铁1的第一凹槽1-1内退出解锁，外缸套5-1继续动作，直到第二锁块4-2滑至锁闭铁1的第二凹槽1-2处，此时，第二锁块4-2被外缸套5-1上的斜面突起结构推动进入第二凹槽1-2内，完成右侧锁闭，外缸套5-1继续动作，使第二锁块4-2达到一定的锁闭深度，防止第二锁块4-2退出第二凹槽1-2解锁，即完成左侧终端位置锁闭到右侧终端位置锁闭的转换。外缸套5-1从右侧终端锁闭位向左侧终端位置锁闭位转换时与上述动作原理相同。
为避免在完成锁闭功能动作后，外缸套5-1发生反向移动，导致锁闭功能失效，在锁闭铁1和外缸套5-1之间设置阻尼机构。图4为本发明的阻尼机构结构示意图。阻尼机构包括摩擦块6-1、弹簧6-2和芯轴6-3。转辙机到终端位置后，摩擦块6-1通过弹簧6-2施加一定的保持力，从而和外缸套5-1产生一定的摩擦力，使外缸套5-1保持在锁闭位置，当外缸套5-1反向运动时需要克服和摩擦块 6-1产生的摩擦力才能运动，以保证转辙机到位后保持在锁闭位置。
尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
