[0033] The technical solution of the folding door device of the gantry side milling head of the present invention has the following advantages:

[0034] 1. The opening speed is faster, improving work efficiency;

[0035] 2. There is no need to reserve a space for the folding door to move on the right side of the milling head entrance and exit 2, so that the folding door saves half of the occupied space compared with the traditional sliding door. Furthermore, the overall space of the folding door device is more reasonable and compact, without affecting the operator's observation;

[0036] 3. The moving range of the folding door is outside the operator, and it will not block the safe area where the operator stands, with higher safety and avoiding machine accidental injury;
