其中，如图2和3所示，基座1上安装固定有安装座5，安装座5包括固定部51、第一安装部52和第二安装部53，固定部51为方形块状结构，固定部51的中部具有第一通孔，相应地，基座1上具有与第一通孔相对的第二通孔，通过螺栓或螺钉依次贯穿第二通孔、第一通孔，并通过螺母紧固，实现基座1与安装座5之间的固定。另外，螺母与安装座的固定部51之间还可以设有压紧套54，压紧套54的中部具有第三通孔，用于螺栓或螺钉的贯穿，压紧套54的下端面的尺寸大于上端面的尺寸，压紧套54的下端面抵靠在安装座的固定部51上，压紧套54的上端面直接与螺母接触，提高基座与安装座之间固定的稳定性。固定部51朝向基座的缺口11的一侧向竖直方向延伸构成第一安装部52，第一安装部52为平面结构；另外，固定部51与第一安装部52之间弧形过渡，避免应力集中。固定部51上与朝向基座的缺口11的一侧相邻的另一侧向竖直方向延伸构成第二安装部53，第二安装部53也为平面结构；另外，固定部51与第二安装部53之间弧形过渡，避免应力集中。第一安装部52所处的平面与第二安装部53所处的平面垂直，以便装配第一摆臂3和第二摆臂 4。第一摆臂3的摆动面与第一滚轮所在平面、第一安装部52的平面平行，第二摆臂4的摆动面与第三滚轮所在平面、第二安装部53的平面平行。
具体地，如图3所示，第一摆臂3为凹形结构，包括摆动连接部31以及位于摆动连接部两侧的第一滚轮连接部32、第二滚轮连接部33，安装座的第一安装部52的中部具有第一穿孔521，相应地，第一摆臂的摆动连接部31的中部具有与第一穿孔相对的第二穿孔311，第一轮轴6依次贯穿第一摆臂上的第二穿孔311、安装座上的第一穿孔521后，垫入第一大平垫7、第一弹垫，再旋入第一螺钉9，使得第一摆臂3能绕第一轮轴6摆动，即第一摆臂3与第一安装部52摆动连接。第一摆臂的第一滚轮连接部32和第二滚轮连接部33的顶端分别安装第一滚轮21和第二滚轮22，具体地，第一摆臂的第一滚轮连接部32的顶端具有第一装配孔321，第二滚轮连接部33的顶端具有第二装配孔331，一轴承压入第一滚轮21的轴承孔内，再装入弹性挡圈，然后压入销轴，销轴穿过弹性挡圈、轴承后，伸出第一滚轮之外后，再穿过隔套及第一摆臂的第一装配孔321，垫入大平垫、弹垫，旋入螺钉，即完成第一滚轮21安装在第一摆臂3上；其中，隔套的两端面分别顶于第一滚轮和第一摆臂的外侧面。相类似的，一轴承压入第二滚轮22的轴承孔内，再装入弹性挡圈，然后压入销轴，销轴穿过弹性挡圈、轴承后，伸出第二滚轮之外后，再穿过隔套及第一摆臂的第二装配孔331，垫入大平垫、弹垫，旋入螺钉，即完成第二滚轮22安装在第一摆臂3上；其中，隔套的两端面分别顶于第二滚轮和第一摆臂的外侧面。第一滚轮21、第二滚轮22以及第一摆臂3安装完成后，第一摆臂3的摆动面与第一滚轮21所处平面平行，即也与第二滚轮22所处平面平行。另外，第一摆臂3的底部为弧形结构，即摆动连接部、第一滚轮连接部、第二滚轮连接部三者呈现两侧高、中间低的弧形结构，弧形结构的弧心所在的方向朝向凹形结构的第一摆臂1的凹口，使得第一摆臂3的摆动行程扩大，使得第一滚轮21和第二滚轮22与电梯导轨的适配性更佳。
如图2所示，第二摆臂4为L形结构，包括竖直部41和水平部42，水平 部与竖直部之间的连接处弧形过渡，且水平部与竖直部之间的连接位置具有第三穿孔，安装座的第二安装部具有与第三穿孔相对的第四穿孔，第二轮轴60依次贯穿第二摆臂上的第三穿孔、安装座上的第四穿孔后，垫入第二大平垫、第二弹垫，再旋入第二螺钉，使得第二摆臂4能绕第二轮轴60摆动，即第二摆臂4与第二安装部53摆动连接。第二摆臂4安装完成后，其水平部42朝向背离第一安装部52所处的方向。第二摆臂的竖直部41的顶端具有第三装配孔，一轴承压入第三滚轮23的轴承孔内，再装入弹性挡圈，然后压入销轴，销轴穿过弹性挡圈、轴承后，伸出第三滚轮之外后，再穿过隔套及第二摆臂的第三装配孔，垫入大平垫、弹垫，旋入螺钉，即完成第三滚轮23安装在第二摆臂4上，且第三滚轮23处于安装座5的正上方，第二摆臂4的摆动面与第三滚轮23所处平面平行；其中，隔套的两端面分别顶于第三滚轮和第二摆臂的内侧面。
另外，第二摆臂4及第一摆臂的第二滚轮连接部33位于安装座5的同一侧。第一摆臂的第一滚轮连接部32还具有安装孔322，安装孔322位于第一装配孔321的正下方，安装孔322用于安装第一弹性调节机构a，第一弹性调节机构a用于调节第一摆臂的位置以实现找平。具体地，第一弹性调节机构a包括第一垫块a1、第一螺杆a2、第一弹簧a3、第二弹簧a4、弹簧座a5和第一螺母a6，第一垫块a1与第一摆臂的安装孔322通过螺栓或螺钉连接，第一垫块a1具有竖向穿孔a11，第一螺杆a2依次贯穿基座1、第一弹簧a3、第一垫块的竖向穿孔a11、第二弹簧a4、弹簧座a5和第一螺母a6，并通过第一螺母a6压紧，且第一螺杆a2的底端与基座1的底面齐平；其中，弹簧座a5和第一螺母a6之间还可以设置大平垫和弹垫；第一弹簧a3和第二弹簧a4分别用于对第一摆臂3朝两个摆动方向的摆动提供回复力。
如图2、4和5所示，第二摆臂4朝向第一摆臂的第一滚轮连接部的一侧安装有第二弹性调节机构b，第二弹性调节机构b用于对第二摆臂4的摆动提供回复力。具体地，第二摆臂的水平部42具有安装孔，该安装孔用于安装第 二弹性调节机构b；第二弹性调节机构b包括第二垫块b1、第二螺杆b2、第三弹簧b3和第二螺母b4，第二垫块b1与第二摆臂的安装孔通过螺栓或螺钉连接，第二垫块具有竖向穿孔b11，第二螺杆b2依次贯穿基座1、第三弹簧b3、第二垫块的竖向穿孔b11和第二螺母b4，并通过第二螺母b4压紧，且第二螺杆b2的底端与基座1的底面齐平。其中，第二垫块b1和第二螺母b4之间还可以设置大平垫和弹垫；第三弹簧b3用于对第二摆臂4的摆动提供回复力。
为了便于将滚轮导靴安装固定在电梯的相应位置处，基座1具有多个安装孔，包括腰型孔、圆孔等。
另外，上述第一弹簧、第二弹簧和第三弹簧还可以为弹性橡胶等其它弹性件。
本实施例的滚轮导靴，将第一滚轮和第二滚轮的摆臂合二为一，使得第一滚轮与第二滚轮联动；且只需设置一个弹性调节结构，即可对第一滚轮、第二滚轮与电梯导轨之间的压紧力进行调节；即使电梯处于超重或偏载状态时，滚轮导靴两侧的第一滚轮和第二滚轮均能与导轨接触，降低滚轮脱轨的概率，电梯运行更加稳定。
实施例二：
本实施例的滚轮导靴与实施例一的不同之处在于：
第一摆臂的左、右两侧分别通过第一弹性调节机构安装在基座之上，即第一摆臂能够通过两侧的第一弹性调节机构调节第一摆臂的位置，实现滚轮导靴结构的多样化。
其它结构可以参考实施例一。
实施例三：
本实施例的滚轮导靴与实施例一的不同之处在于：
第一摆臂的左、右两侧均不安装第一弹性调节机构，仅通过第一摆臂联动第一滚轮和第二滚轮，也能使得滚轮导靴两侧的第一滚轮和第二滚轮均能与导轨接触，使得滚轮导靴的结构简化，实现滚轮导靴结构的多样化。
其它结构可以参考实施例一。
以上所述仅是对本发明的优选实施例及原理进行了详细说明，对本领域的普通技术人员而言，依据本发明提供的思想，在具体实施方式上会有改变之处，而这些改变也应视为本发明的保护范围。
