[0035] Working principle: This embodiment provides a lifting electric tractor. First, when the electric tractor body 1 lifts the bottom beam of the cargo trolley, the position of the L-shaped mounting plate 402 on the coarse adjustment column 4 is adjusted in advance, and the position of the L-shaped lifting seat 5 is roughly adjusted. Then, the electric tractor body 1 is moved to make the L-shaped lifting seat 5 correspond to the bottom beam of the cargo trolley. Then, the L-shaped lifting seat 5 is driven to rise by the oil cylinder 3, and the position of the L-shaped lifting seat 5 is finely adjusted so that the L-shaped lifting seat 5 is pressed against the bottom beam of the cargo trolley. In the process of the L-shaped lifting seat 5 being pressed against the bottom beam of the cargo trolley, the mounting rod 6 is rotated and the mounting rod 6 is rotated toward the opening groove 5. 01, the limit plate 7 will flip upwards at this time, and when the L-shaped lifting seat 5 is completely pressed against the bottom beam of the cargo trolley, the limit plate 7 will rotate to a vertical state, and the electric push rod 8 will be controlled to extend and insert into the fixing hole 601 of the mounting rod 6, so as to fix the limit plate 7, and the limit plate 7 and the L-shaped lifting seat 5 form a concave structure, which is engaged on the bottom beam of the cargo trolley, so that the front and rear sides of the bottom beam of the cargo trolley can be blocked and limited, which can effectively prevent the L-shaped lifting seat 5 from being separated from the bottom beam of the cargo trolley when the electric tractor body 1 drives the cargo trolley to move, and ensure that the electric tractor body 1 can stably drive the cargo trolley to move;
[0036] Secondly, in the process of the limit plate 7 rotating to a vertical state, the combination bar 901 in the limit structure 9 on the opposite side of the limit plate 7 and the L-shaped lifting seat 5 will undergo adaptive telescopic displacement. Therefore, when the bottom beam of the cargo trolley is a rectangular rod, the corresponding combination bar 901 on the limit structure 9 will be displaced to form a rectangular clamping groove to buckle the bottom beam of the cargo trolley. When the bottom beam of the cargo trolley is a circular rod, the corresponding combination bar 901 on the limit structure 9 will be displaced to form an arc-shaped clamping groove to buckle the bottom beam of the cargo trolley. Therefore, with the cooperation of the limit structure 9, the bottom beam of the cargo trolley will not slide out from the top of the concave structure formed by the combination of the L-shaped lifting seat 5 and the limit plate 7, which can further improve the stability of the connection between the L-shaped lifting seat 5 and the bottom beam of the cargo trolley.
