Snow sweeper hanger lifting limiting device
The invention discloses a snow sweeper hanger lifting limiting device which comprises a hanger with a rolling brush, the hanger is connected with a connecting frame through an upper lifting arm, a lower lifting arm and an oil cylinder, a lifting arm connecting plate is hinged between the upper lifting arm and the lower lifting arm, and an upper limiting plate and a lower limiting plate are arranged at the hinged position for limiting. One end of an oil cylinder is connected to the connecting frame, the other end of the oil cylinder is hinged to the upper lifting arm, a limiting plate pin hole is formed in the lower limiting plate, and a hanging frame pin hole is formed in the position, coinciding with the limiting plate pin hole, of the hanging frame when the oil cylinder stretches out and draws back to the maximum degree; the quick-release steel ball pin is used for connecting and fixing the limiting plate pin hole and the hanger pin hole when the oil cylinder stretches to the maximum extent; and the quick-release steel ball pin is provided with a hook which is convenient to take and place. Compared with the prior art, the problems that an existing snow sweeper hanging frame lifting limiting device is insufficient in supporting force on a rolling brush, the lifting reliability of the rolling brush is low, and potential safety hazards exist can be solved.
本发明公开了一种除雪车挂架提升限位装置，包括带有滚刷的挂架通过上提升臂和下提升臂及油缸连接连接架，所述上提升臂和所述下提升臂之间铰接有提升臂连接板，并在铰接处分别设有上下限位板限位，油缸一端连接在所述连接架上，另一端铰接在所述上提升臂上，所述下限位板设有限位板销孔，在所述油缸伸缩到最大时所述挂架上与所述限位板销孔重合位置设有挂架销孔；还包括在所述油缸伸缩到最大时将所述限位板销孔和所述挂架销孔连接固定的快拆钢珠销；所述快拆钢珠销设有方便取放的挂钩。本发明与现有技术相比，可以解决现有除雪车挂架提升限位装置对滚刷的支撑力度不够，滚刷升降的可靠性较低，存在安全隐患的问题。
