Airport underpass construction trolley with automatic demolding function

The invention discloses an automatic demolding airport underpass construction trolley, and belongs to the technical field of airport building equipment and equipment.The outer side face of an inner formwork frame is longitudinally provided with a plurality of longitudinal U-shaped grooves, a plurality of longitudinal partition plates are arranged in the longitudinal U-shaped grooves at intervals, and transverse kidney-shaped holes are formed in the longitudinal partition plates; the template demolding rotating shaft is inserted into a transverse kidney-shaped hole in the longitudinal U-shaped groove, a demolding gear is arranged on the template demolding rotating shaft in a sleeving manner, and strip teeth are arranged in the longitudinal U-shaped groove corresponding to the demolding gear; due to the fact that the spatial position of the formwork demoulding rotating shaft is fixed, when the formwork demoulding rotating shaft is rotated, the inner formwork frame can be controlled to move inwards and outwards,
