[0033] The lifting device is installed at the rear end of the carriage 21 of the transport vehicle 2, and livestock enter and exit the carriage through the lifting device; the lifting warehouse 1 moves up and down to a suitable height, and the lifting warehouse 1 adapts to the height of the carriage. Livestock can be safely transferred between the lifting warehouse 1 and the carriage through the front door 14.

[0034] The lifting platform 11 is folded upward by the flip hinge 15, and the lifting compartment 1 is stored at the rear end of the carriage to ensure transportation safety; the lifting platform 11 is laid flat by the flip hinge 15, and the lifting compartment 1 is released, so that livestock can safely enter and exit the carriage through the lifting compartment 1.

[0035] The connecting door 16 is arranged between the front warehouse door 14 and the side rail 13, and a storage space is formed between the front end of the side rail 13 and the front warehouse door 14. When the lifting platform 11 is folded upward, the storage space can store the folded side rail 13, and the lifting platform 11 can be folded upward to a vertical direction to ensure safety and reliability after storage; after the lifting platform 11 is laid flat and the lifting warehouse 1 is released, the connecting hinge 161 is arranged between the connecting door 16 and the side rail 13, and the connecting door lock 162 is arranged between the connecting door 16 and the front warehouse door 14, which ensures the strength of the connection between the front warehouse door 14 and the side rail 13.

[0036] The connecting door lock 162 is provided with a connecting latch 1621 and a connecting lock sleeve 1622. The connecting lock sleeve 1622 is provided with a connecting lock hole 1623, and the connecting latch 1621 can be inserted into the connecting lock hole 1623; the connecting latch 1621 is movably provided on the connecting door 16, and the connecting lock sleeve 1622 is provided on the front compartment door 14.

The connecting latch 1621 is provided with a compression portion 1626. The front end of the compression spring 1625 is abutted against the rear end of the compression portion 1626 and is compressed by the compression portion 1626, which can prevent the connecting latch 1621 from sliding backward out of the connecting lock hole 1623, thereby ensuring the reliability of the connecting door lock 162.

[0043] The lift 1 also has a rear door 18 hinged to the side rails. The lift 1 is adapted to the height of the area outside the vehicle, allowing livestock to be safely transferred between the lift 1 and the area outside the vehicle through the rear door 18. In this embodiment, two rear doors 18 are also provided, each hinged to a corresponding side rail.

[0044] The side rails 13 are hinged to the lifting platform 11 , and the side rails 13 on both sides are folded inwards to be close to the upper end surface of the lifting platform 11 so as to be conveniently stored.

[0045] The lifting device is also provided with a lifting mechanism 3, which is provided with a support frame 31 and a lifting slide 32, and the lifting slide 32 is movably arranged in the support frame 31; the support frame 31 is arranged at the rear end of the carriage 21 along the vertical direction, and the connecting frame 12 is linked to the lifting slide 32.
