The invention relates to a portal crane fixing device and belongs to the technical field of fixing devices. The technical scheme is that the portal crane fixing device comprises a stationary wedge block, a hinge pin, a movable wedge block, an adjusting bolt, an adjusting handwheel, a positioning nut, a spring, a lifting handle, a connecting rod and a positioning plate. The stationary wedge block is connected to the bottom of a protecting cover through the hinge pin and can rotate at a certain angle; the adjusting bolt penetrates the side surface of a shell of the protecting cover through a thread, and the adjusting bolt is provided with the positioning nut and the handwheel. The movable wedge block is connected to the lifting handle through the connecting rod, and the lifting handle is fixed to the upper part of the shell of the protecting cover. The spring is mounted on the connecting rod in a sleeving manner. A groove is formed in the shell of the protecting cover below the lifting handle. The portal crane fixing device has the advantages of being safe and reliable to fix, strong in locking force, free of sliding, simple in structure, convenient to operate, time-saving and labor-saving and the like.
