A car washing machine and a top brush lifting device and a lifting counting mechanism thereof, the car washing machine comprises the top brush lifting device, the top brush lifting device comprises the lifting counting mechanism, and the lifting counting mechanism comprises a counting disc which is arranged at one end of a tape winding shaft of the top brush lifting device and synchronously rotates along with a tape winding wheel installed at the end of the tape winding shaft; a plurality of counting holes are uniformly formed in the counting disc at equal intervals in the circumferential direction of the counting disc; the counting sensor corresponds to the counting disc, is mounted on a top brush cross beam of the top brush lifting device and is connected with a controller, the counting disc synchronously rotates forwards or backwards along with the tape winding wheel, and the counting sensor senses hole position changes of counting holes in the counting disc and correspondingly outputs ascending or descending counting pulses; and the controller calculates the instant height of the top brush of the car washer through the ascending or descending counting pulse. The top brush height detection device is simple in structure and convenient to install, the top brush height detection accuracy is further improved, and top brush height control is more stable and reliable.
一种洗车机及其顶刷升降装置和升降计数机构,该洗车机包括顶刷升降装置,该顶刷升降装置包括升降计数机构,该升降计数机构包括:计数盘,设置在顶刷升降装置的卷带轴的一端,并随安装在该卷带轴该端的卷带轮同步转动,该计数盘沿其圆周方向上均匀等间隔设置多个计数孔;以及计数传感器,对应于该计数盘安装在该顶刷升降装置的顶刷横梁上,并与控制器连接,该计数盘随该卷带轮同步正转或反转,该计数传感器感应该计数盘上的计数孔的孔位变化,并对应输出上升或下降计数脉冲,该控制器通过该上升或下降计数脉冲计算得到洗车机顶刷的即时高度。本发明结构简单,便于安装,进一步提高了顶刷高度检测的精确性,使得顶刷高度控制更稳定可靠。
