Description

一种具有防失稳功能的桥梁检查车转向架 技术领域
本发明涉及桥梁检查车技术领域，尤其是一种具有防失稳功能的桥梁检查车转向架。
 背景技术
桥梁检查车由于转向架上部的车体上安装有桥梁检查设备，当桥梁检查车在桥梁上进行桥梁检查作业时，桥梁检查设备中装有检查人员的吊篮会伸至桥梁下方，在伸出过程中桥梁检查设备需经历伸缩垂直臂、旋转/伸缩吊篮臂、提升/降低/旋转主臂等一系列的动作，当发生这些动作时，转向架上方承载的重量再次分配，承载重心发生偏移，转向架轮重产生不均匀，检查设备伸出侧产生轮重增载、另一侧产生轮重减载现象。现有转向架二系采用橡胶堆，转向架与车体之间相对较灵活，当转向架上部承载重量发生偏心时，转向架与车体间容易发生失稳，尤其在行车作业时，这种失稳现象将加剧，导致整个车辆容易发生倾覆翻车，存在较大的安全隐患。

 本发明的实施方式
如图1至3是本发明的结构示意图，一种具有防失稳功能的桥梁检查车转向架，包含构架1，所述构架1底部安装有轮对2，所述构架1呈H型，包含侧梁一1-1、侧梁二1-2和横梁1-3，所述横梁1-3上安装有动力装置3，所述动力装置3与轮对2的车轴相连，所述构架1底部安装有制动装置4，所述制动装置4与轮对2的车轮相连，所述侧梁一1-1和侧梁二1-2设置有支撑车体的旁承5，所述横梁1-3中部固定有牵引装置6，所述构架1和车体间固定有锁紧装置7，所述锁紧装置7包含挂钩结构8和使挂钩结构8锁紧的顶升油缸9。
具体结构分析如下：构架1为本申请的承载结构，构架1通过旁承5与车体相连，构架1下方安装有轮对2，构架1上安装动力装置3、制动装置4、牵引装置6和锁紧装置7；动力装置3为轮对2提供动力，驱动轮对2在钢轨上前行；制动装置4与车轮相连，提供基础的制动动作；旁承5通过上定位销与车体上的旁承座连接，通过下定位销与构架1侧梁的上盖板连接，起到支撑车体，缓冲转向架与车体间的冲击的作用；牵引装置6上端通过螺栓与车体连接，下端与构架1相连，从而将转向架上产生的纵向力（牵引力和制动力）传递到车体上部；锁紧装置7是将车体与转向架之间形成刚性连接的结构，在桥梁检察车作业前，顶升油缸9的活塞杆端部伸出，顶至构架1上盖板，由于锁紧装置7的挂钩结构8与车体连接，顶升油缸9承载车体上升的同时使锁紧装置7锁紧，转向架与车体间处于刚性联接，由此平衡由于转向架承载重量的重心发生偏移而引起的偏转力矩，避免了转向架与车体间失稳现象的发生。当桥梁检查车在正常行驶的非检查作业工况下，顶升油缸9的活塞杆不会伸出，顶升油缸9不起作用，锁紧装置7不起作用。
根据本发明的另一个实施例，进一步包括，所述动力装置3包含电机3-1和齿轮箱3-2，所述电机3-1和齿轮箱3-2通过挠性齿式联轴节3-3相连，所述齿轮箱3-2通过轴承与轮对2的车轴相连。
如图1和图4所示，当桥梁检查车处于牵引工况时，电机3-1将电能转变为驱动扭矩，通过齿轮箱3-2驱动轮对2在钢轨上行进，从而推动桥梁检查车前进，挠性齿式联轴节3-3，由于桥梁检查车在运行时，电机3-1和齿轮箱3-2之间有相对浮动，而挠性齿式联轴节3-3包含两个半联轴节和一组连接法兰组，具有扭转刚性，齿连接使用自动定心轮齿，扭矩传递通过一对具有渐开线齿形的外齿（鼓形齿）和内齿（内齿筒）进行联锁实现，因此，挠性浮动齿式联轴节3-3能很好地完成动力传递。
根据本发明的另一个实施例，进一步包括，所述动力装置3通过架悬结构10固定在构架1的横梁1-3上，所述架悬结构10包含电机吊座10-1和齿轮箱座10-2，所述电机3-1通过螺栓固定在电机吊座10-1，所述齿轮箱3-2通过螺栓固定在齿轮箱座10-2。
如图1、3和4所示，与传统滚抱电机悬挂结构的电机部分重量要由车轴承担不同，通过架悬结构10可以将动力装置3的重量全部施加在构架1上，架悬结构10具有结构简单、灵活性大、传递效率高、减少安装空间等特点，传统的架悬结构，电机输出端与齿轮箱必须相对固定才能传递动力，不能适应电机与齿轮箱存在相对位移的结构，且传统的架悬结构在结构组成上相对复杂，需有空心轴套等铸件组成，对安装精度及制造质量要求高。
根据本发明的另一个实施例，进一步包括，所述构架1与轮对2之间通过轴箱悬挂装置11相连，所述轴箱悬挂装置11包含轴箱11-1、浮动弹簧11-2和减振器11-3，所述浮动弹簧11-2和减振器11-3的一端分别固定在轴箱11-1上部，另一端与构架1侧梁的下盖板相连，所述轮对2的车轴端部转动连接于轴箱11-1中。
如图1和图5所示，轴箱悬挂装置11是联系轮对2与构架1的活动关节，起传递载荷、固定轴距的作用，当桥梁检查车牵引时，还起到传递牵引力、制动力以及垂向载荷和横向载荷的作用；轴箱11-1上固定的浮动弹簧11-2，在桥梁检查车运行时能允许轴箱11-1相对于构架1有适当的上下浮动，桥梁检查车运行时，电机3-1和齿轮箱3-2之间有相对浮动，而构架1相对轮对2通过浮动弹簧11-2上下浮动加以适应，因此能更好地完成动力的传递，同时，浮动弹簧11-2与架悬结构10的设计相应，架悬结构10将动力装置3的重量施加在构架1上，相对传统的结构（动力装置安装在车轴上），减轻浮动弹簧11-2下部的重量，避免由于簧下太重而导致对轮轨的冲击过大，使得转向架获得良好的动力学性能，而减振器11-3能够减轻轮对2与构架1的振动，保证运行的平稳性。
根据本发明的另一个实施例，进一步包括，所述制动装置4包含两组带停放功能的单元制动器4-1和两组常用单元制动器4-2，所述带停放功能的单元制动器4-1和常用单元制动器4-2间通过制动管路4-3相连。如图1和图6所示，带停放功能的单元制动器4-1使桥梁检查车获得在一定的距离内速度减慢或停放的功能。
根据本发明的另一个实施例，进一步包括，所述构架1上固定有拉杆制动组合座12，所述单元制动器通过螺栓与拉杆制动组合座12相连，所述拉杆制动组合座12与轴箱11-1的侧部相连。
根据本发明的另一个实施例，进一步包括，所述牵引装置6包含中心销6-1、牵引块6-2和两个牵引杆6-3，其中，中心销6-1和牵引块6-2转动连接，牵引块6-2的两端分别与两个牵引杆6-3相连而呈Z型，所述中心销6-1通过螺栓与车体相连，所述牵引杆6-3与设置在横梁1-3下盖板的牵引座6-4相连。
如图1、7、8和9所示，“Z”字形牵引装置结构最大可能地降低了牵引点高度，牵引点与轨面的高度降至342mm，以最大程度地减少桥梁检查车的轴重转移，避免了由于轴重转移过大而对桥梁检查车黏着重量利用的影响，桥梁检查车的牵引力能够得到充分的发挥。牵引装置6简单紧凑，且在同一平面，在牵引过程中，一侧牵引杆6-3受拉，另一侧牵引杆6-3受压，牵引位置6具有很好的对中性，有利于牵引力的传递。中心销6-1和牵引块6-2的连接处的衬套6-5采用尼龙衬套6-6过渡，便于后期维护便利。
根据本发明的另一个实施例，进一步包括，所述构架1横梁1-3上固定横向减振器13，所述横向减振器13的另一端与车体相连。进一步缓解转向架与车体间的振动。
根据本发明的另一个实施例，进一步包括，所述挂钩结构8包含安装在侧梁上的吊钩座8-1和安装在车体上的吊钩8-2，所述吊钩8-2挂在吊钩座8-1上。
如图10所示，当顶升油缸9活塞杆伸出使车体上升时，吊钩8-2也跟随上升，直至吊钩8-2与构架1上的吊钩座8-1锁紧刚性连接，从而达到车体与转向架的连接为刚性连接的目的。由于桥梁检查车在检查作业时产生偏转力矩，此结构可以避免原有车体与转向架橡胶堆连接的过于灵活现象，使得桥梁检查车在检查作业时更加稳定，不会产生倾覆危险。
根据本发明的另一个实施例，进一步包括，所述吊钩8-2具有两个对称布置的钩部8-3，所述吊钩座8-1有两个，分别和两个钩部8-3相连。进一步保证锁紧装置7的稳定性。
以上说明对本发明而言只是说明性的，而非限制性的，本领域普通技术人员理解，在不脱离所附权利要求所限定的精神和范围的情况下，可做出许多修改、变化或等效，但都将落入本发明的保护范围内。
