The invention relates to the technical field of battery mounting and dismounting, in particular to a replaceable battery mounting and dismounting system which comprises an electric forklift, a battery mounting and dismounting device, a battery mounting and dismounting device and a battery mounting and dismounting device. A lifting rod is arranged at the end of the battery pack, a limiting rod is arranged at the end of the lifting rod, a fixing plate is arranged on the surface of the battery pack, and a second screwing plate is installed at the end of the electric forklift; the top clamping groove is formed in the surface of the fixing plate; the electric forklift has the beneficial effects that a fixing plate and a lifting plate are arranged at the end of the electric forklift, a loading and unloading oil cylinder is arranged on the surface of the lifting plate and drives the lifting plate to ascend and descend, so that a limiting rod is located in a limiting groove, the position of a battery pack is limited, the lifting plate extends to the bottom of a lifting rod, and a bottom clamping groove is clamped to the bottom of the lifting rod; after the lifting plate ascends, the battery pack is lifted, when the lifting plate ascends to the highest position, the top of the lifting rod is clamped in the top clamping groove, and the lifting rod is fixed through the bottom clamping groove and the top clamping groove.

本发明涉及电池安装和拆卸技术领域，具体为一种用于可更换电池安装和拆卸系统，包括：电动铲运车，电动铲运车的端部设置有固定板；电池组，电池组的端部设置有提升杆，提升杆的端部设置有限位杆，电池组的表面设置有固定板，电动铲运车的端部安装有第二螺接板；及顶部卡槽，设于固定板的表面；有益效果为：本发明提出的电动铲运车的端部设置有固定板和升降板，升降板的表面设置有装卸油缸，装卸油缸带动升降板进行升降，使得限位杆位于限位槽中，限定电池组的位置，升降板伸到提升杆的底部，使得底部卡槽卡在提升杆的底部，升降板上升后将电池组抬升，当升降板上升至最高处时，提升杆的顶部卡在顶部卡槽中，底部卡槽和顶部卡槽将提升杆固定住。
