quickly-replaced runner wheel type road roller

QI MINGZHU / ZHAO ZHIZHONG

The invention discloses a quickly-replaced runner wheel type road roller, and relates to the technical field of road rollers. A rolling wheel of the road roller is rotationally connected to a machine body through a connecting arm, the rolling wheel comprises a wheel body and a connecting shaft rotationally arranged on the central axis of the wheel body, the connecting arm comprises a connecting frame, the connecting frame comprises a transverse arm, the transverse arm is connected with the machine body, longitudinal arms perpendicular to the transverse arm are arranged at the two ends of the transverse arm, and movably-connected positioning rods are arranged at the tail ends of the longitudinal arms. The connecting shaft is connected with the cross arm through a fastening mechanism, the fastening mechanism comprises a connecting groove which is formed in the cross arm and matched with the height of the connecting shaft, and a transverse positioning assembly and a longitudinal positioning assembly are arranged in the connecting groove. According to the road roller, an operator can conveniently disassemble and assemble the runner wheel on the road roller, on one hand, the operation difficulty of the operator during maintenance of the runner wheel is reduced, on the other hand, the operation efficiency is improved, and the situation that the use efficiency is reduced due to the fact that the road roller is idle for a long time is avoided.

本发明公开了一种快换碾轮式压路机，涉及压路机技术领域。该压路机的碾轮通过连接臂转动连接在机体上，碾轮包括轮体和转动设置在轮体中轴线上的连接轴，连接臂包括连接框架，连接框架包括横臂，横臂与机体连接，横臂两端设有与横臂垂直设置的纵臂，纵臂末端设有活动连接的定位杆，连接轴与横臂之间通过紧固机构连接，紧固机构包括开设于横臂上匹配连接轴高度的连接槽，连接槽内设有横向定位组件和纵向定位组件，本发明能够在需要对碾轮进行更换检修或打磨时将碾轮快速更换，方便操作人员对其压路机上的碾轮进行拆卸和安装，一方面降低了操作人员对碾轮检修时的操作难度，另一方面也提升了操作效率，避免压路机长时间闲置而导致的使用效率降低。
