Sweeper anti-falling structure and motor sweeper
The sweeper anti-falling structure comprises a lock hook and a tension spring, the first end of the tension spring is fixedly arranged, and the second end of the tension spring is connected with the lock hook and tensions the lock hook through first tension; the locking cylinder is communicated with the chassis gas circuit and is in transmission connection with the latch hook, when the driving force applied to the latch hook by the locking cylinder is larger than the first pulling force, the latch hook is located at the unlocking position, and when the driving force applied to the latch hook by the locking cylinder is smaller than the first pulling force, the latch hook is located at the locking position; and the limiting shaft is fixedly arranged on a shaft body of the sweeping brush assembly, when the lock hook is located at the locking position, the lock hook is clamped with the limiting shaft so as to limit the falling motion of the sweeping brush assembly, and when the lock hook is located at the unlocking position, the lock hook avoids the motion path of the limiting shaft. Under the action of the lock hook and the tension spring, the locking position is switched in advance when the gas path leaks so as to clamp and limit the limiting rod, so that the sweeping assembly is prevented from falling off due to insufficient driving action of the air cylinder. The invention further discloses a motor sweeper.
本发明公开了一种扫刷防脱落结构，包括：锁钩和拉簧，拉簧的第一端固定设置，第二端与锁钩连接并以第一拉力拉紧锁钩；锁紧气缸，连通底盘气路并与锁钩传动连接，锁紧气缸对锁钩施加驱动力大于第一拉力时，锁钩位于解锁位置，锁紧气缸对锁钩施加驱动力小于第一拉力时，锁钩位于锁紧位置；限位轴，固定设置于扫刷组件的轴体上，锁钩位于锁紧位置时与限位轴卡接以限位扫刷组件的下落运动，锁钩位于解锁位置时避开限位轴的运动路径。本发明通过锁钩和拉簧作用，在气路泄漏时提前切换至锁紧位置以对限位杆进行卡接限位，从而避免扫刷组件由于气缸驱动作用不足而掉落。本发明还公开了一种清扫车。
