The invention discloses an electric pallet truck. The electric pallet truck comprises a front frame, a rear frame, and a telescopic driving cylinder used for driving the rear frame to move relative tothe front frame and further comprises a microswitch and a starting piece. One of the microswitch and the starting piece is fixed to a cylinder body of the telescopic driving cylinder, and the other one of the microswitch and the starting piece is fixed to a telescopic rod of the telescopic driving cylinder. The starting piece is in sliding fit with one, which is provided with the microswitch, ofthe cylinder body and the telescopic rod in the telescopic direction of the telescopic driving cylinder, and when the telescopic rod extends out and moves to the starting piece to trigger the microswitch, the microswitch responds to enable the telescopic rod to stop extending out. The microswitch and the starting piece are installed on the telescopic driving cylinder and thus can be protected along with the telescopic driving cylinder, the deviation of the starting part relative to the microswitch is very small, and therefore the electric pallet truck can effectively solve the problem that thestopping detection effect of the rear frame of the electric pallet truck is poor.
本发明公开了一种电动托盘搬运车,包括前车架、后车架和用于驱动后车架相对前车架移动的伸缩驱动缸,还包括微动开关和发动件,微动开关和发动件中,一个固定在伸缩驱动缸的缸体上、另一个固定在伸缩驱动缸的伸缩杆上,发动件与缸体和伸缩杆中安装有微动开关的一个沿伸缩驱动缸伸缩方向滑动配合,以在伸缩杆伸出移动到发动件激发微动开关时,微动开关响应以使伸缩杆停止伸出。将该微动开关和活动件安装在伸缩驱动缸上,有利于跟随伸缩驱动缸一起被保护,同时发动件相对于微动开关的偏差特别小,所以该电动托盘搬运车能够有效地解决电动托盘搬运车后车架停止检测效果不好的问题。
