如图3所示，本发明的一种辊筒1000，包括：杆轴1010、安装端1020、中空筒体1030、第一凸块1040、第二凸块1050、弹簧1060；安装端1020为第一安装端1120和第二安装端1220，分别设置在杆轴1010两端；中空筒体1030套合在安装端1020的外表面，第一安装端1120、第二安装端1220分别与中空筒体1030的两端挤压固定；第一凸块1040和第二凸块1050，分别为两个，第一凸块1040设置在紧挨第一安装端1120内侧的杆轴上，第二凸块1050设置在离第二安装端1220具有预定距离的杆轴上；弹簧1060套装在第二凸块1050和第二安装端1220之间的杆轴上，或第一凸块1040和第一安装端1120之间的杆轴上。使用凸块将杆轴卡在第一安装端1120和第二安装端1220之间，有效地防止杆轴从辊筒中脱落。安装端1020包括：圆筒形端体1021以及位于端体内表面的轴承1022，轴承可通过位于端体内壁上的环形凹槽安装在安装端上，杆轴1010穿过轴承1022的中心与中空筒体1030滚动安装，杆轴1010与安装端1020通过轴承可转动连接。
如图4所示，为了减少了凸块与轴承之间和弹簧与轴承之间的摩擦磨损，第一凸块1040和所述第一安装端1120的轴承1022之间以及弹簧1060与第二安装端1220的轴承1022之间设置有环状挡圈1070，该环状挡圈1070可活动的安装在所述凸块与轴承1022之间的杆轴1010上或固定安装在轴承1022面对凸块的一侧。轴承1022为角接触球轴承，杆轴1010与该轴承1022的内壁固定配合。圆筒形端体1021为尼龙套，具有弹性，可将第一安装端、 第二安装端挤压进入中空筒体内。
为了便于辊筒的安装，在杆轴的两端可设置用于使杆轴固定安装并阻止杆轴转动的安装部，该安装部可以是供螺钉穿过的通孔或可卡入安装槽的卡条、卡块或其它形式的卡入部件。
本发明的一种地滚装置分为前轮地滚装置2和后轮地滚装置4；前轮地滚装置2设置在安装平台1上车辆前轮停靠处；后轮地滚装置4设置在安装平台1上车辆后轮停靠处。
限位装置6分别设置在前轮地滚装置2与后轮地滚装置4之间，定位器3与后轮地滚装置4之间，且分别安装在安装平台1和移动平台7上，移动平台可以设置在换电移动平台上。此外，安装平台1上铺设有底板8，以使安装平台1表面平整。底板8可以为整体一块，但为了方便安装最好分为多块分别安装。本实施例中底板8为花纹钢板。
地滚装置包括：地滚安装板、辊筒1000和拆卸板25；地滚安装板具有用于安装辊筒1000的安装槽，安装槽内的相对两侧开设有安装孔，安装时，先将具有弹簧的位于第二安装端的杆轴插入安装槽内的安装孔中，再挤压位于第一安装端的杆轴，使杆轴向第二安装端方向移动，从而使第一安装端的杆轴插入位于安装槽内的另一个安装孔内，从而使辊筒1000安装在地滚安装板内；如图2所示，辊筒1000安装完毕后，在第一安装端的安装孔的上方设置拆卸板25，可拆卸地盖合在地滚安装板安装孔上方，并且与底板8保持平整密封，需要拆卸辊筒1000时，先拆卸该拆卸板25，再挤压位于安装孔内的杆轴，使杆轴从安装孔内移出。安装孔开设在所述地滚安装板顶端的横条或安装片上。
如图5所示，前轮地滚装置2为辊筒1000安装在前轮地滚安装板21上，车辆定位时，一个前轮在前轮地滚装置2上处于浮动状态，随着定位器3上的前轮定位调整，前轮地滚装置2上的前轮同步自我调整。本实施例中，在前轮地滚安装板21上安装有四个辊筒1000，都为弹簧压入式，安装时辊筒 1000直接压入在前轮地滚安装板21内即可。如图2所示，前轮地滚安装板21通过第一螺栓安装在第一支架111上。
如图6所示，后轮地滚装置4包括：后轮地滚安装板平行部41、后轮地滚安装板敞开部42和辊筒1000；后轮地滚安装板平行部41与车辆行驶方向平行，后轮地滚安装板敞开部42与车辆行驶方向按预定角度敞开。辊筒1000分别设置在后轮地滚安装板平行部41、后轮地滚安装板敞开部42上。本实施例中，后轮地滚安装板平行部41和后轮地滚安装板敞开部42分别安装有4个和6个辊筒1000，并且都为弹簧压入式。后轮地滚安装板敞开部42安装的辊筒1000比前轮地滚安装板平行部41多，是因为后轮地滚安装板敞开部42用于车辆前期引导定位，引导定位时，车轮在上面滑动，更多的辊筒1000提供更大的面积有利于车轮定位。如图2所示，后轮地滚安装板平行部41和后轮地滚安装板敞开部42为一整体，通过第一螺栓安装在第三支架113上。
如图7所示，地滚安装板安装上辊筒1000后的剖面图。弹簧压入式的辊筒1000压入地滚安装板后，辊筒1000的杆轴1010会露出安装孔，按下杆轴1010的露出端可拆下辊筒1000。因此在拆卸板25的设置即保证了底板8的平整防止灰尘，又方便了辊筒1000的拆除。
如图8所示，本发明的一种限位装置6包括：限位安装板61和辊筒1000，限位安装板61为L型安装板，包括底板和竖直板，竖直板上设有辊筒1000安装孔，辊筒1000通过该安装孔安装在限位安装板61的竖直板上，安装在竖直板上的辊筒1000可沿杆轴自由滚动。限位安装板61的底板上开设有腰形孔611上，限位安装板61通过穿过腰形孔611的螺钉安装在安装平台上。限位装置6分别设置在位于同一侧的前轮地滚装置2与后轮地滚装置4之间，以及位于另一侧的定位器3与后轮地滚装置4之间。
在本实施例中，限位装置6为两组，一组安装在安装平台1上，另一组安装在移动平台7上，限位安装板61通过穿过腰形孔611的螺钉安装在安 装平台1上，有利于微调这两组限位装置6之间的距离，该限位安装板上设有供辊筒的杆轴插入的安装孔。辊筒1000为图3或4所示辊轮。如图3或4所示，辊筒1000内设置有弹簧1060使得辊轮具有弹性，最优每个限位安装板61上安装有两个辊筒1000，安装时两个辊筒1000的压入端依次插入限位安装板上的安装孔，且两个辊筒头尾相邻，朝同一方向方便拆卸，即相邻的两个辊筒1000的端点，一个为离弹簧1060近的端点一个不是。腰形孔的采用使得限位装置安装方便，并且通过腰形孔调节减小制造过程中产生的距离误差。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
