Description

自走式轨道除沙车 技术领域
本发明属于铁路轨道维护设备技术领域，尤其涉及一种自走式轨道除沙车。
背景技术
众所周知，铁路运输是交通体系中不可取代的运输方式之一。由于铁路铺设遍布全国各地，受到各种地理环境的影响，而处于风沙多发地带的交通线路由于受到风沙的危害，经常导致列车晚点，严重的甚至会发生列车侧翻。风沙的危害一方面堆积在线路的基础设施内阻碍列车的正常运行；另一方面风沙常年磨损铁路基础设施，还增加了列车脱轨的危险，存在极大的安全隐患。
目前，巡视、清沙等维护铁路基础设施的工作主要依靠人力来完成，由于人工清沙工作量大，导致工作效率低下。
发明内容
本发明的目的是提供一种自走式轨道除沙车，旨在解决上述现有技术中依靠人工清理轨道内积沙劳动强度大、工作效率低的技术问题。
为解决上述技术问题，本发明所采取的技术方案是：
一种自走式轨道除沙车，包括驾驶室、行走装置和集沙排沙装置，所述驾驶室内设有控制行走装置和集沙排沙装置的控制台，所述集沙排沙装置设置于驾驶室的前方，所述行走装置设置于驾驶室的下方；所述行走装置设置于驾驶室底部的底盘上，所述行走装置包括与轨道配合的行走轮、工作轮和从动轮，所述行走轮、工作轮和从动轮均设置于底盘上，快速行走的行走轮由动力部件驱动，低速行进的工作轮由驱动部件驱动，所述动力部件及驱动部件均由控制台控制，所述行走轮和工作轮通过升降部件交替与轨道配合。
优选的，所述行走轮、工作轮和从动轮均为两个，所述行走轮设置于工作轮的前方，所述从动轮设置于工作轮的后方；两个行走轮之间设有驱动桥，所述动力部件通过传动轴与驱动桥相连，所述驱动桥通过升降部件与底盘相连。
优选的，所述传动轴的两端通过联轴器分别与动力部件及驱动桥相连。
优选的，所述驱动部件设置于底盘内部，所述动力部件设置于底盘的底部。
优选的，所述动力部件为液压马达，所述液压马达与控制台电连接。
优选的，所述升降部件为液压缸，所述液压缸的两端分别与底盘及驱动桥转动连接。
优选的，所述底盘上设有安装座，所述液压缸的缸体与安装座转动连接，所述驱动桥上设有连接座，所述液压缸的活塞杆末端与连接座转动连接。
采用上述技术方案所产生的有益效果在于：与现有技术相比，本发明通过升降部件实现行走轮与工作轮交替与轨道配合，驾驶人员在驾驶室通过控制台即可操纵驱动部件和动力部件，来适应清沙工作状态时的低速行驶和转场时的高速行驶，满足低速行驶清理轨道内积沙、高速行驶快速转场的需求。利用本发明能够降低工作人员的劳动强度，提高清沙工作效率，保证了列车的行车安全。

图2是图1中行走装置在清沙时的工作状态图；
图3是图1中行走装置在快速行走时的状态图；

具体实施方式
下面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、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，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。
如图1-3所述的一种自走式轨道除沙车，包括驾驶室1、行走装置和集沙排沙装置00，所述驾驶室1内设有控制行走装置和集沙排沙装置00的控制台，所述集沙排沙装置00设置于驾驶室1的前方，所述行走装置设置于驾驶室1 的下方；所述行走装置设置于驾驶室1底部的底盘2上，所述行走装置包括与轨道3配合的行走轮4、工作轮5和从动轮6，所述行走轮4、工作轮5和从动轮6均设置于底盘2上，快速行走的行走轮4由动力部件10驱动，低速行进的工作轮5由驱动部件驱动，所述动力部件10及驱动部件均由控制台控制，所述行走轮4和工作轮5通过升降部件7交替与轨道3配合。驾驶人员在驾驶室通过控制台控制升降部件实现行走轮与工作轮交替与轨道配合，满足低速行驶清理轨道内积沙及高速行驶快速转场的需求。其中，集沙排沙装置的具体结构在专利《斗轮式轨道除沙车》(申请号2019102166201)中有详细描述，在此不再赘述。
作为一种优选结构，所述行走轮4、工作轮5和从动轮6均为两个，所述行走轮4设置于工作轮5的前方，所述从动轮6设置于工作轮5的后方；两个行走轮4之间设有驱动桥8，所述动力部件通过传动轴9与驱动桥8相连，所述驱动桥8通过升降部件7与底盘2相连。其中，驱动桥与现有技术中汽车后桥的结构相同，驱动桥包括主减速器、桥壳和与行走轮相连的半轴，动力部件通过传动轴将动力传递至驱动桥，首先经主减速器主动轴上的主动锥齿轮传送至从动锥齿轮，将动力转换90°，同时降低转速、增大扭矩；然后依次将动力传递至差速器壳、十字轴、行星齿轮、半轴齿轮和半轴，最后由两半轴传递至两侧的行走轮，进而驱动行走轮沿轨道快速行驶。同时，驱动桥也方便驱动行走轮在地面上直行或拐弯，当两侧行走轮所受地面阻力不同时，行星齿轮在公转运动的同时还绕十字轴轴线转动(自传)，两侧行走轮将以不同的转速旋转，差速器起差速作用，方便驱动整体设备在不同路面上行驶。
为了有效传递扭矩，所述传动轴9的两端通过联轴器11分别与动力部件10及驱动桥8相连。其中，联轴器11选用万向节联轴器。
在本发明的一个具体实施例中，如图1所示，所述驱动部件设置于底盘2内部，所述动力部件10设置于底盘2的底部。该方案中的驱动部件与挖掘机底盘中的驱动装置结构相同，驱动部件由低速大扭矩液压马达、制动器、阀组等组成，由于在清理积沙时所需行驶速度较慢，低速大扭矩液压马达驱动工作轮 低速转动，进而驱动工作轮沿轨道低速行驶，满足清沙过程中的慢速行走。
由于驾驶室底部设有挖掘机驱动装置，具有完整的液压系统，所述动力部件10选用液压马达，所述液压马达与控制台电连接。以驾驶室的液压系统作为动力源，通过控制台驱动液压马达转动，进而驱动行走轮快速转动。
同理，所述升降部件7选用液压缸，以驾驶室的液压系统作为动力源，所述液压缸的两端分别与底盘2及驱动桥8转动连接。在底盘2上设有安装座12，所述液压缸的缸体与安装座12转动连接，所述驱动桥8上设有连接座13，所述液压缸的活塞杆末端与连接座13转动连接。当处于清沙工作状态时，液压缸的活塞杆回缩将行走轮抬起，使工作轮与轨道轨面接触，进入工作状态；当清沙完毕，快速转场时，液压缸的活塞杆伸出，将行走轮落下顶起工作轮，使行走轮与轨道轨面接触，进入快速转场状态。
综上所述，本发明具有结构可靠、方便维护、行驶速度可调的优点，利用液压马达及传动轴将动力传递至驱动桥，进而能够驱动行走轮方便快速转场；借助底盘上的驱动部件实现工作轮的低速转动，方便沿着轨道缓慢清理积沙。驾驶人在驾驶室内通过控制液压缸实现工作轮与行走轮的交替与轨道接触，实现慢速清沙及快速转场的两个需求；利用集沙排沙装置将沙子铲起并倾倒至传送带上，排至轨道左侧或右侧。利用本发明无需人工除沙，工作人员仅需坐在驾驶室内即可完成清沙工作及转场要求，极大降低了工作人员的劳动强度，提高了清沙的工作效率，保证了列车的行车安全。
在上面的描述中阐述了很多具体细节以便于充分理解本发明，但是本发明还可以采用其他不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似推广，因此本发明不受上面公开的具体实施例的限制。
