如图2所示,所述液压驱动机构21包括柴油发动机211、分动箱、液压泵212及液压管。所述液压管分别与所述第一动力机构22和所述第二动力机
构23连通。
如图8和图9所示,所述第一轨道24包括并列且间隔设置的两条钢轨,即普通的双轨结构。
如图5、图8和图9所示,所述第二轨道25为一条工字轨,包括沿竖直方向设置的第一板体252,和分别设于所述第一板体252上、下表面的第二板体251和第三板体253,所述第二板体251和所述第三板体253分别与所述第一板体252垂直设置。所述第二轨道设置在两条所述钢轨之间。
所述轨枕26的铺设方向和隧道的长度方向垂直设置,平行且间隔设置于所述第一轨道24和第二轨道25的下方,包括位于所述轨枕26两端附近的第一轨道安装部261和位于所述轨枕26中部的第二轨道安装部262,所述第二轨道安装部262的高度高于所述第一轨道安装部261的高度。所述第一轨道安装部261上设有固定卡板263和活动卡板264,所述固定卡板263和所述轨枕26固定连接,比如可以采用焊接的方式固定,而所述活动卡板264则与所述轨枕26可拆卸连接,比如可采用螺栓等连接方式。第一轨道24卡接于所述固定卡板263和活动卡板264之间。
如图8至图10所示,所述第二轨道25底部固定连接有第二轨道固定板254,所述第二轨道固定板254与所述轨枕26可拆卸连接。所述第二轨道25由多根工字轨拼接而成,两根相邻的工字轨的底部分别设有互相配合的连接部255,所述连接部255一端与所述工字轨的底部固定连接,另一端则通过连接件与相邻工字轨的连接部255固定连接。两个连接部255倾斜设置,两个连接部255连接的一端互相靠近。
如图1所示,所述第一动力机构22用于平地运输,包括安装于所述轨道运输车底部的车轮221及车轮马达222。所述液压驱动机构21驱动车轮马达222旋转,车轮马达222带动车轮221旋转,从而提供平地运输所需的动力,驱动车轮221沿所述第一轨道24走行。。
如图5所示,所述第二动力机构23用于爬坡运输,包括固定架233、夹紧结构驱动装置236、两组夹紧结构231、支撑轮234、导向轮组件235、及制动结构232。
所述固定架233设于所述第二轨道25上方并与所述轨道运输车底部固定连接。
如图6所示,两组所述夹紧结构231分别设于所述第一板体252的两侧,每组所述夹紧结构231均包括安装臂2311、设于所述安装臂2311上的摩擦轮驱动装置2312、及与所述摩擦轮驱动装置2312的驱动端固定连接的摩擦轮2313。所述安装臂2311一端与所述固定架233铰接,另一端与所述夹紧结构驱动装置236铰接。所述夹紧结构驱动装置236穿设并凸出于所述固定架233设置,当所述夹紧结构驱动装置236伸长时能够使两组夹紧结构231的摩擦轮2313朝互相远离的方向移动,从而松开所述第一板体252,即第二动力机构23关闭;而当夹紧结构驱动装置236缩回时能够使两组夹紧机构的摩擦轮2313朝互相靠近的方向移动,从而夹紧所述第一板体252,即第二动力机构23开启。所述摩擦轮2313为钢轮外包裹聚氨酯结构,钢轮可以使摩擦轮的整个结构更为稳固,而包裹聚氨酯材料后则可以增加摩擦力,以为轨道运输车提供充足的爬坡动力。
具体地,在本实施例中所述夹紧结构驱动装置236为液压油缸,所述摩擦轮驱动装置2312为液压马达,所述摩擦轮驱动装置2312用于驱动摩擦轮2313转动。所述摩擦轮驱动装置2312和所述夹紧结构驱动装置236均由所述液压驱动机构21提供驱动力。
两个支撑轮234分别设于所述摩擦轮2313两侧的第二板体251的上方,通过轴承与固定架233底部连接。所述支撑轮234为钢轮,所述支撑轮234沿所述第二板体251的上表面走行,在轨道运输车运行时可为整个编组提供支撑力,使整个编组的运行更加平稳。
每组导向轮组件235分别设于所述支撑轮234附近的固定架233上。每组所述导向轮组件235均包括两个导向轮支架板2351和分别设于所述导向轮支架板2351侧壁上的导向轮2352,所述导向轮支架板2351与固定架233固定连接,每组所述导向轮组件235中的所述导向轮2352对应设置在所述第一板体252的两侧,且能够沿所述第三板体253的上表面走行。所述导向轮2352为钢轮,设置在所述导向轮支架板2351和所述第一板体252之间。所述导向轮2352通过轴承与所述导向轮支架板2351连接。导向轮组件235的设置限
制了固定架233的下缘与第三板体253之间的距离,防止摩擦轮2313与第二轨道25的第二板体251和第三板体253发生碰撞。
如图7所示,所述制动结构232包括制动结构驱动装置2321、弹性件2322、及两组刹车组件。所述弹性件2322套设于所述制动结构驱动装置2321外。所述刹车组件包括制动臂2323、支杆2324、及制动闸瓦2325。所述制动臂2323的两端分别与所述制动结构驱动装置2321和制动闸瓦2325的一端铰接,所述支杆2324与所述制动臂2323的中部铰接;所述两组刹车组件分别位于所述第一板体252的两侧;所述制动结构驱动装置2321伸长或缩回时能够使所述制动闸瓦2325夹紧或松开所述第一板体252。在本实施例中,所述制动结构驱动装置2321为液压油缸,由液压驱动机构21提供驱动力。所述制动结构232与所述导向轮组件235配套设置,共有两组。所述制动结构232的支杆2324一端与所述制动臂2323铰接,另一端则固定于所述导向轮支架板2351上。所述制动结构驱动装置2321穿设并凸出于所述固定架233设置。所述制动闸瓦2325穿设并凸出于所述导向轮支架板2351设置,所述导向轮支架板2351可以为制动闸瓦2325的运动提供导向。
本实施例的动力***适用于平地运输,同时也适用于爬坡运输。当在平地上运输时,第一运输机构提供牵引力。当爬坡运输时,则第一动力机构22和第二动力机构23同时提供牵引力。第二轨道25的第一板体252的表面作为提供摩擦动力的接触面,两个摩擦轮2313将第一板体252夹紧,可以有效增大摩擦力,防止爬坡失败。而第二轨道25的第二板体251则可用来提供支撑力,使轨道运输车运行得更加平稳。且该动力***整体结构简单、可靠,有效降低了生产制造成本及维护保养成本,有效减小了设备故障发生的几率,确保轨道运输车安全、有效地运行。
如图1至图3所示,本发明一些实施例的轨道运输车编组包括运输车辆及上述的动力***。
具体地,在本实施例中,所述运输车辆包括依次连挂的人员车、机车11、第一动力平板车12、第一动力车13、第二动力车、第二动力平板车、第一渣土车、第二渣土车、第三渣土车、砂浆车、平板车、第一管片车、第二管片车和第三管片车。
所述第一动力车13和第二动力车上设有所述液压驱动机构21,第一动力车13和第二动力车结构相同,设置两台动力车能够有效提高整个编组的运动速度。
所述机车11上设有所述第一动力机构22.
所述机车11、第一动力平板车12和第二动力平板车上分别设有两套所述第二动力机构23,两套第二动力机构23依次设于对应车辆的前后轮之间。
此编组设置为本实施例的最优方案,可以在保证整体性能的基础上进行任意调整。在本实施例中,增设第一动力车13和第二动力车的目的首先是为了避免将液压驱动机构21设置在机车11上导致机车11整体高度过高,适用于隧道整体高度受限的轨道运输车编组,如不受高度限制,则可将液压驱动机构21设置于机车11上,减少成本的同时,也减少了连挂的整体长度。再者,两台动力车能够有效提高整个编组的运行速度,适用于对运动速度要求较高的编组,如对运动速度无具体要求,则也可以设置一台动力车。
如图1和图4所示,本发明另一些实施例的轨道运输车编组与上述的轨道运输车编组类似,不同的是,本实施例的运输车辆包括依次连挂的人员车、机车11、动力车、渣土动力车14、第一渣土车、第二渣土车、砂浆车、平板动力车、第一管片车、第二管片车和第三管片车。
所述动力车上设有所述液压驱动机构21。
所述机车11、动力平板车和渣土动力车14上分别设有所述第二动力机构23,所述机车11上还设有第一动力机构22。
本发明的轨道运输车编组设计合理,其中一个实施例的轨道运输车的动力***较为集中,能够有效减少接线的长度,同时为整个编组提供充足的动力和较高的爬坡速度。而另一个实施例的轨道运输车的动力***相对较为分散,接线长度较长,但其动力输出更为平稳,更有利于轨道运输车的平稳运输,其动力更为缓和,速度较低。
虽然本公开披露如上,但本公开的保护范围并非仅限于此。本领域技术人员在不脱离本公开的精神和范围的前提下,可进行各种变更与修改,这些变更与修改均将落入本发明的保护范围。
